Description

[Detailed description of the invention]

The present invention relates to a copying apparatus, and more specifically, to a copying apparatus called an enlarge printer that copies enlarged images at a plurality of magnifications from a microfilm held on an aperture card onto copy paper of a plurality of sizes. . More specifically, the present invention relates to a copying apparatus that is capable of enlarging and copying onto larger copy sheets by setting an aperture card as an information piece to an exposure position in two ways. A conventionally known enlargement printer is a device that enlarges and projects an image on a microfilm and copies it onto copy paper.It is an optical device that appropriately enlarges and projects an image on a microfilm and forms the image on a photoreceptor of a copying device. It consists of a combination of a photocopier and a copying device using an electrophotographic device, etc. As a copying device, a slit exposure method using a photoreceptor drum is desired due to the need for faster copying speed. . In a slit exposure type copying apparatus using such a photoreceptor drum, an optical image obtained by scanning and projecting a microfilm image is formed on the photoreceptor drum so that it moves synchronously with the movement of the photoreceptor drum. , an enlarged image of the microfilm image is formed as a latent image on a photosensitive drum, and the latent image is developed and then transferred and fixed onto copy paper by a process of a conventionally known electrophotographic apparatus. By the way, the manuscript to be photographed on microfilm is
There are many industrial drawings, etc., and the standard size is A0 to A4 according to the Japanese Industrial Standards. Furthermore, the reduction ratios for photographing these originals have been standardized according to their respective sizes. Furthermore, although specific numerical values will be discussed in the explanation of the examples, the center position of the image of the microfilm held on the aperture card is determined by the dimensions from the long and short sides of the aperture card. are different from each other. Therefore, in a copying machine that automatically feeds an aperture card to obtain a copy, even if you try to make a copy larger than the maximum size that can be obtained with the machine, the difference between the card and the microfilm will result. Because the positions are standardized, it is impossible or only half-finished copies can be obtained. For example, if the copying machine automatically feeds aperture cards and is loaded with a 594 mm wide (long side of A2 size, short side of A1 size) copying roll paper, the card will be placed horizontally. Assuming that it is sent, you will only be able to obtain copies of the maximum size of A2. Therefore, if the aperture card is fed vertically, an A1-sized copy can be obtained, but feeding the card in both the long and short sides only unnecessarily complicates the mechanism. It is. Additionally, the relative position of the microfilm to the exposure device must be maintained strictly, but if the aperture card can be fed vertically or horizontally,
There is a problem that positioning the card is extremely complicated. Furthermore, in order to obtain large-sized copies,
It would be sufficient to prepare the photosensitive drum, equipment necessary for the copying process arranged around it, and copy paper of the desired size, but this would only increase the bulk of the apparatus. The present invention has been made in view of the above, and includes:
To provide a copying device capable of producing large-sized copies without increasing the length of a photosensitive drum. This also means that the function of enlarged copying from microfilm can be expanded by selectively combining a plurality of enlargement copy magnifications and a plurality of sizes of copy paper. The object of the present invention is to provide a copying apparatus that obtains a copy by exposing a microfilm image of an aperture card illuminated by an illumination device to a photoreceptor.
a carriage that holds the aperture card with a transparent glass pressure bonding plate provided at a predetermined position and scans and moves the exposure optical axis between the illumination device and the photoreceptor in a direction in which the microfilm of the card crosses; card feeding means for feeding an aperture card to a predetermined position on the carriage along the long side direction and in a direction perpendicular to the scanning movement direction of the carriage; A guide groove that guides the lower part of the aperture card, and a card rear end stopper that positions the aperture card fed by the feeding means at a predetermined position in the long side direction. a first positioning means configured to be movable between a retracted position and a retracted position; a positioning means provided in the carriage for pressing the upper part of the aperture card; and a retracted position retracted from the positioning position; a horizontal card positioning device having a card upper guide movable between positions and a second positioning means for positioning the aperture card at a predetermined position in the short side direction thereof by the guide groove; and a horizontal card positioning device held in the carriage. a card ejecting device for ejecting the aperture card from the cartridge along the exposure scanning direction; and a card ejecting device for ejecting the aperture card from the cartridge along the exposure scanning direction; When manually inserting the card into the guide groove of the above-mentioned carriage, there is a card abutting part that positions the manually inserted card in the long side direction; a vertical card positioning device having a card guide member that is movable between the card guide members, and when the card contact portion is positioned at the positioning position by the card guide member, the rear end of the card is This is achieved by a copying apparatus characterized in that the stopper and the card upper guide are respectively retracted from each positioning position. According to the present invention, since the aperture card is selectively positioned in the vertical position and the horizontal position, it is possible to obtain copies of two sizes from copy paper having one size width. . For example, enlarged copies of A2 size (420 x 594) and A1 size (594 x 841) can be obtained from a roll paper for copying with a width of 594 mm. According to a detailed feature of the present invention, the means for positioning the long side of the information piece in the feeding direction cancels the positioning operation of the means for positioning the long side of the information piece in the scanning movement direction, so that the aperture card When the card is placed in the vertical position, the scanning movement direction positioning means when horizontally feeding the card does not get in the way. Furthermore, since the means for positioning the long side of the information piece in the feeding direction cancels the positioning operation of the means for positioning the short side of the information piece in the feeding direction, when placing the aperture card in the vertical position, the micro The center of the image on the film is made to coincide with the center of the light beam of the exposure system. More specific features of the invention will be described in detail in the description of the embodiments. The details of the present invention will be explained below with reference to embodiments shown in the drawings. FIG. 1 is an external view of an embodiment of a microfilm enlargement printer to which the present invention is applied, and FIG. 2 is a sectional view schematically showing its internal configuration, in which the microfilm image enlargement projection device 46 is an electrophotographic copying device. It is placed on top of a copying device 47 that uses a copying machine. In the enlarged projection device 46, the micro film 61 attached to the rectangular window of the aperture card 2 (see FIG. 3) is held in a vertical position on a flat surface by glass pressure bonding plates 93, 93a made of transparent glass plates. There is a carriage 111 which scans and moves upward in FIG. It is enlarged and projected by the lens 8, reflected by the first mirror 20 and the second mirror 21,
The microfilm 61 is scanned and moved so that the optical image formed on the photosensitive drum 31 moves synchronously with the moving speed of the photosensitive drum 31. The photosensitive drum 31 rotates in the direction of the arrow, is uniformly charged by a charging device 32, and forms a latent image of an enlarged image of the microfilm 61 in the exposure slit section 28. The enlarged image developed by the developing device 33 is transferred by a transfer charging device 34 to a copy sheet 43a that is fed a predetermined copy sheet, for example 43, by a paper feed device 42 and cut into a predetermined length by a cutter 50. The copy paper 43a, which has been transferred from the photoreceptor drum 31 and separated from the photoreceptor drum 31 by the separation and charging device 35, has the transferred image fixed by the fixing device 38, and is transferred to the copy paper 43a by the conveying device 39 and the paper ejection roller 40.
The paper is discharged to the paper discharge tray 41. On the other hand, the cleaning device 36 removes the residual toner on the surface of the photoreceptor drum 31 that has residual toner after the transfer, the residual charge is removed by the static eliminator 37, and the photosensitive drum 31 is uniformly charged again by the charging device 32. , and then repeat the above operations. The copying operation performed by the photosensitive drum 31 and its related devices is no different from that in conventionally known electrophotographic apparatuses, so a detailed explanation will be omitted. Hereinafter, the device of the present invention will be explained in detail for each specific operation and device. Aperture Card Feeding As shown in FIG. 14, the aperture cards 2b loaded into the card hopper 82 are
The pressing plate 83 gives it a tendency to move in the direction of the arrow by the urging of a spring (not shown). A separation roller 85 is disposed at the card outlet 82a of the card hopper 82, and a separation knife 81 is connected to the leading edge of the separation roller 85 at a position substantially opposite to the separation roller 85.
5, with a gap sufficient to allow only one aperture card to pass through. In response to an operation signal from the copy start switch 561 (see FIGS. 1 and 40), the separation roller 85
The drive motor 103 rotates the aperture card 2b in the card hopper 82 in a counterclockwise direction through a transmission pulley, a belt, and an electromagnetic clutch 85c (not shown), and cooperates with the separation knife 81 to The aperture cards 2 are fed one by one to the card feeding path 101 in the long side direction from the side closer to the separation roller 85. The aperture card 2 sent out from the card hopper 82 is transferred to two-sheet feed detection rollers 86 and 1.
02, but when two or more aperture cards 2 are fed simultaneously, this is detected and the detection signal micro switch is activated so that the feeding of the aperture cards 2 is stopped. The position of the detection roller 86 is adjusted so that the detection roller 87 is activated. The aperture card 2 that has passed the two-sheet feed detection rollers 86 and 102 is rotated by a drive motor 103 via a pulley and a belt (not shown), and is driven by a first feed roller 88 and a solenoid 90. , the card is fed in the card feeding direction (to the right in the figure) along the feeding path 101 by the first pinch roller 89 in contact with this. After passing through the first detection element 91, the carriage 1 shown in FIG.
The aperture card 2, which has its lower edge tip entered into the guide groove 114 of No.
While rotating the card counterclockwise around the
Card upper guide 1 forming part of the positioning means of

15 clockwise around the shaft 115a (see FIG. 16), the first feeding roller 88
and the first pinch roller 89, the carriage 1
11 guide grooves 114. This card 2 is attached to the glass pressure bonding plate 9 which is placed in the open position by the operation of the solenoid 141 (see FIG. 16).
3 and 93a, and is rotatably driven by the drive motor 103 via a pulley and belt (not shown), and a second feed roller 94 that comes into contact with the solenoid 96 by urging the solenoid 96. The tip of the aperture-your-card 2 passes through the third detection element 97 and comes into contact with the card positioning lever 98, and the spring 9
The card positioning lever 98, which has been given a counterclockwise rotational habit by 8a, is rotated clockwise, but an activation signal from the third detection element 97 caused by the passage of the tip of the aperture card 2 causes the first pinch roller to rotate. The solenoid 90 that energizes the feed roller 89 and the solenoid 96 that energizes the second pinch roller 95 are de-energized, and the first feed roller 88 and the second
The feeding roller 94 loses its ability to feed the aperture card 2. At the same time, the power to the drive motor 103 that rotationally drives the separation roller 85, first feed roller 88, and second feed roller 94 that constitute the card feeding means is cut off, and the drive motor 103 rotates. stop. When the second pinch roller 95 comes out of contact with the second feeding roller 94, the aperture card 2 is moved in the feeding direction due to the counterclockwise rotational behavior of the positioning lever 98 that comes into contact with the tip of the aperture card 2. However, when the aperture-your-card 2 contacts the positioning lever 98 and rotates it clockwise, the aperture-your-card 2 is pushed back in the opposite direction, that is, to the left in FIG. The rear end is already the card rear end stopper 92
The rear end stopper 92 of the card passes through the tip of the card abutting surface 92b (see FIG. 31), and the card rear end stopper 92 is biased by a spring (not shown) to the shaft 92a (see FIG. 31).
The aperture-your-card 2 rotates clockwise around the guide groove 114, and its tip enters the guide groove 114 and comes into contact with the wall recess 114a (see Fig. 31), and the rear end of the aperture-your-card 2 reaches the card rear end stopper. 92, the aperture card 2 is held between the positioning lever 98 and the card rear end stopper 92, as shown in FIG. By doing so, the long side direction is positioned at a predetermined position. That is, as shown in FIG. 31, the card rear end stopper 92 has a positioning position in which the long side of the card is positioned at a predetermined position by abutting the rear ends of the aperture cards, and a position centered on the axis 92a. It is rotatably provided to be movable between a retracted position in which the card contact surface 92b is retracted from the guide groove 114, and constitutes a first positioning means. At this predetermined position, the center of the rectangular window for attaching the microfilm of the aperture card 2 in the long side direction is aligned with the optical axis position of the projection lens 8 (see FIG. 15). On the other hand, in the short side direction of the aperture card 2, as shown in FIGS. 15 and 16, the card upper guide 115
is pivotally attached to the upper part of the carriage 111, and the shaft 1 is rotated by the bias of a spring (not shown).
The aperture card 2 fed to the carriage 111 is rotated counterclockwise around the aperture card 15a (see FIG. 16).
It always acts to press against the guide groove 114 of No. 1. However, the pressing force of the card upper guide 115 is
Aperture your card 2 is the card positioning lever 9
Due to the rotational behavior of 8, the aperture card 2 acts in a state that does not prevent its position from being moved in the long side direction.
With its lower long side in contact with the guide groove 114 of No. 1, its position in the short side direction is determined. Therefore, the card upper guide 115 has a positioning position (FIG. 15) where the upper part of the card is pressed and a retracted position (16th position) where it is retracted from this positioning position.
(Fig.), and constitutes a second positioning means for pressing the aperture card against the guide groove 114 that guides the lower part of the card and positioning it in the direction of its short side. . This second positioning means and the card rear end stopper 92 constitute a lateral card positioning device that positions an aperture card fed along its long side at a predetermined position. As described above, the tip of the aperture card 2 passes through the third detection element 97, which generates an activation signal, thereby rotating the holder 93b around the shaft 93c against the compression spring 142. By cutting off the power to the solenoid 141 via the delay circuit, the aperture card 2 is positioned at a predetermined position in the carriage 111.
The microfilm 6 is attached to the rectangular window of the aperture card 2 by the glass pressure bonding plate 93a fixed at a predetermined position of the carriage 111 and the glass pressure bonding plate 93 held by the holder 93b.
1 is held flat so that it is perpendicular to the optical axis of the projection lens 8 (see FIG. 15). The aperture card 2b in the hopper 82 that follows the aperture card 2 fed and positioned by the carriage 111 is pressed by the pressing plate 83 so that the aperture card 2a on the side closer to the separation roller 85 is moved to the separation roller. 85 and separation knife 81
The aperture card 2 is sent out from the delivery port 82a to the feeding path 101 so that the leading end of the aperture card 2 is almost in contact with the rear end of the aperture card 2. detection element 91
The generated signal cuts off the power to the transmission electromagnetic clutch 85c from the drive motor 103 to the separation roller 85 via the delay circuit of the control circuit, so that the subsequent aperture card 2a has two leading edges. The feeding by the separating roller 85 is stopped before reaching the feeding detection rollers 86, 102,
The system enters a waiting mode at the position shown in FIG. As will be described later, the subsequent aperture card 2a has undergone exposure scanning for enlarging copying from the preceding aperture card 2, and is then transferred to the card stocker 16 by the card ejection device 163 shown in FIG.
After the cartridge 111 returns to a position where it can feed an aperture card (described later), the card is fed to the carriage 111 in the same way as the preceding aperture card 2 by an activation signal from a predetermined control circuit. Positioned and held. Thereafter, subsequent aperture cards 2b are sequentially fed and positioned and held in the carriage 111 in the same manner, but the last aperture card 2b is fed and the fifth detection element 8
4 detects that there is no aperture card in the hopper 82, the electromagnetic clutch 8 transmits driving force to the drive motor 103 for feeding the aperture card and the separation roller 85.
The signal energizing 5c is cut off. Similarly, when no aperture card is loaded in the card hopper 82, the drive for sending out and feeding the aperture card from the hopper 82 is cut off by the no-card signal from the fifth detection element 84. A similar control circuit is configured. The above is the operation for normal feeding positioning of the aperture your card 2 and the following aperture your cards 2a and 2b, but if for some reason, for example the aperture your card 2 is deformed, the normal feeding is not performed. In consideration of the case where the feeding position is not determined, in this embodiment, damage to the aperture card 2 is prevented, and the aperture card 2 stagnant in the feeding path 101 or the carriage 111 is removed.
can be easily connected to the feed path 101 or the carriage 111.
It has a function of ejecting the aperture card 2 from the feed path 101 to the card stacker 162 (see FIG. 16), and is also designed to allow the aperture card 2 on the feeding path 101 to be fed back to the card hopper 82. The details will be explained below. Jam Card Automatic Ejection At the position where the aperture card 2 is held on the carriage 111 by the card rear end stopper 92 and the card positioning lever 98,
If the carriage 111 does not start the exposure scan due to a jam detection signal due to an abnormality in the feeding of the copy paper 43 in the copying device 47 for some reason, or if the exposure scan is interrupted during the exposure scan, the second Since the detection element 104 and the third detection element 97 detect that the aperture card 2 is positioned in the carriage 111, the carriage 111 is manually operated by the reset switch 564 (see FIG. 40), which will be described later. Main drive motor 305 and electromagnetic clutch 313 shown in FIG.
Or, by the rotation of the pulley 171 which is rotationally driven by the biasing force applied to 317 and 322, the carriage 111 is slid in the direction of the arrow UP shown in FIG.
At the same time as the movement in the UP direction is released, the ejector motor 344, solenoid 153, and solenoid 141 are energized and the aperture card 2
is ejected from the carriage 111 by the card ejecting device 163 from the separated glass pressure bonding plates 93, 93a and placed on the card stacker 162. Further, the solenoid 99 is energized immediately before the carriage 111 moves, thereby avoiding the card positioning lever 98. If feeding is stopped for some reason while the aperture card 2 is in a position where only the second detection element 104 is activated,
As described above, the drive motor 1 is moved so that the aperture card 2 is positioned at a predetermined position on the carriage 111 by manual operation of the reset switch 564.
03, Solenoid 90, 96 and Solenoid 1
41 is energized and the tip of the aperture card 2 activates the third sensing element 97, which causes the carriage 111 to be positioned at a predetermined position. Electromagnetic clutch 313 or 3
17 and 322, the arrow in FIG.
The pulley 171 is slid in the UP direction, and the pulley 171 is rotated in the direction of the arrow for a predetermined period of time by the operation of the timer, and as described above, the aperture card 2 is transferred from the carriage 111 to the card stacker 162 by the operation of the card ejection device 163. is discharged.
It is unnecessary to explain that at this time, the electromagnetic clutch 85c that transmits the rotational drive of the separation roller 85 is not energized. If feeding is stopped while the aperture card 2 is in a position where both the second detection element 104 and the first detection element 91 are activated, the aperture your card 2 operates only the second detection element 104. As in the case where the aperture card 2 is stopped at the operating position, the aperture card 2 is positioned and fed to the predetermined position of the carriage 111 by manual operation of the reset switch 564, and then the card ejection device 163 automatically feeds the aperture card 2 to the card stacker 162. is discharged. Even when the aperture card 2 is in a state where only the first detection element 91 is activated and the rear end is stopped at a position away from the opposing part of the separation roller 85 and the separation knife 81, the above-mentioned case also applies. Similarly, aperture card 2 is temporarily transferred to carriage 11.
1, the carriage 111 is moved in the UP direction in FIG. 17, and after a predetermined movement according to the timer, the reset switch 564 is operated so that the card is ejected to the card stacker 162 by the card ejecting device 163. be able to. When the aperture card 2 is in a state where only the first detection element 91 is activated and the rear end is stopped at a position where it is held between the separation roller 85 and the separation knife 81, the above-mentioned operation is performed. Similarly, by operating the reset switch 564, the aperture card 2 can of course be ejected to the card stacker 162. In addition, this device has a separating roller 85 as shown in FIG. A manual knob 85b is attached to one end of the shaft 85a so as to be exposed at the top of the device so that the separation roller 85 can be rotated clockwise or counterclockwise by manual operation. Therefore, by manually rotating the manual knob 85b in the clockwise direction in FIG. can. When the manual knob 85b is rotated to return the aperture card to the card hopper 82, the two-card feed detection rollers 86, 102 detect that two or more aperture cards are being fed in an overlapped manner. Needless to say, it is effective even when the feeding is automatically stopped upon detection. In this way, when the aperture-your-card 2 stops operating for some reason during its feeding positioning,
The reason why the card can be automatically, reliably and safely ejected to the card stacker 162 by operating the reset switch 564, or returned to the card hopper 82 by manual operation is because this device has the following features. It's only because it's being done. That is, the card hopper 82, separation roller 85, two-sheet feed detection rollers 86, 102 are arranged so that automatic ejection and manual return as described above are possible at any position in the feeding path 101 and the carriage 111 of the aperture card 2. , 1st
This is because the sensing element 91, the second sensing element 104, the third sensing element 97, the glass pressure bonding plates 93, 93a, the first feeding roller 88, and the second feeding roller 94 are arranged. First, since the two-sheet feed detection rollers 86 and 102 are between the first detection element 91 and the separation roller 85, the preceding aperture card 2 is separated from the separation roller 85, and the subsequent aperture card 2a is separated from the separation roller 85. Even when it is detected that these two aperture cards are being fed in an overlapping manner while being held between the separation roller 85 and the separation knife 81, and the feeding is automatically stopped, Only the succeeding aperture card 2b can be returned to the card hopper 82 by rotating the automatic knob 85b, and the preceding aperture card 2b can be automatically ejected as described above by operating the reset switch 564. Ru. That is, the first sensing element 91
The above function is satisfied by being arranged at a distance shorter than the length of the aperture card 2 in the feeding direction from the opposing position of the separation knife 81. Next, the first sensing element 91 and the second sensing element 104
is shorter than the length of the aperture card 2 in the feeding direction, and the glass pressure bonding plates 93, 93a
is arranged between them, and when the presence of the aperture card 2 is detected by either the first detection element 91 or the second detection element 104, the aperture card 2 is separated from the separation roller 85. Separation knife 81 or first feed roller 88 and first pinch roller 89 or second feed roller 9
The above-mentioned function is satisfied by arranging the first feeding roller 88 and the second feeding roller 94 so that the first feeding roller 88 and the second feeding roller 94 can be pinched and fed by either the second pinch roller 95 or the second pinch roller 95. . That is, the first feeding roller 88 and the separation roller 8
5. The distance between the separation knife 81 and the opposing point is shorter than the length of the aperture card 2 in the feeding direction;
Further, the distance between the first feeding roller 88 and the second feeding roller 94 is also shorter than the length of the aperture card 2 in the feeding direction. Thirdly, the third sensing element 97 and the second sensing element 10
The fact that the distance 4 is also shorter than the length of the aperture card 2 in the feeding direction also satisfies the above-mentioned function. That is, as described above, the first feeding roller 88, the second
Solenoids 90 and 96 that control the operation of the feed roller 94 and the first pinch roller 89 and second pinch roller 95 that face them are controlled to be deenergized by a signal from the third detection element 97. It is. Also, a card positioning lever 98 for positioning the aperture card 2.
As described above, the avoidance control is also activated by energizing the solenoid 99 in response to a signal from the third detection element 97. Furthermore, the third detection element 97 also has a function of detecting an abnormality in the feeding of the aperture card 2 and stopping the feeding operation. That is, from the time when the aperture card 2 begins to be fed from the card hopper 82 at a normal speed,
Since the time required for the third detection element 97 to detect the arrival of the leading end of the aperture card 2 is almost constant, the third detection element 97 detects the arrival of the aperture card 2 from the card hopper 82 within a predetermined time. When the aperture card 2 is not activated, a so-called jam detection is performed by operating a time comparison circuit that determines that there is some abnormality in the feeding of the aperture card 2. It is controlled to stop the transmission. After eliminating the cause of the abnormality, the aperture card can be automatically ejected or returned to the card hopper 82 by operating the reset switch 564 or the manual knob 85b as described above. In addition, this device has an initial clear signal generated by turning on the main switch 521 to clear the feed path 10 before feeding the aperture card 2.
1. Carriage 111 and card ejection device 16
Even if there is a remaining aperture card in No. 3, the control circuit is configured so that the above-mentioned automatic ejection operation is also activated to eject the remaining aperture card. Registration The aperture card 2 is positioned at a predetermined position in the carriage 111, and the microfilm 6
1 is pressed and held by the glass pressure bonding plates 93, 93a, the carriage 111 moves the aperture card 2 to expose and scan the microfilm 61.
However, depending on the combination of the selected enlargement projection magnification and the selected copy paper size, the size of the image on the microfilm that can be enlarged and copied onto the copy paper is limited. Ru. Therefore, before scanning the exposure of the microfilm 61, the carriage 111 must be moved upward (in the direction of the arrow UP in FIG. 15) until the predetermined exposure scanning start position and one end of the above-mentioned restriction image coincide. It won't happen. In this example, the enlargement copying magnification is ^10x ,
Three types, 14.5 ^x and 20 ^x, are available, and the enlarged copy magnification can be selectively changed by operating the enlarged copy magnification selection key 542 (see FIG. 39). On the other hand, regarding the microfilm images, many of the microfilm photographic manuscripts in this example are industrial drawings, etc., and their dimensions are A4 or A4 according to the Japanese Industrial Standards.
Standard sizes are A3, A2, A1, and A0. The reduction ratio used to photograph these manuscripts has also recently been standardized.
A4 size uses a reduction ratio of 1/15, A3 size uses a reduction ratio of 1/15 or 1/21.2, A2 size uses a reduction ratio of 1/15 or 1/21.2, A1 size uses a reduction ratio of 1/21.2, and A0 size uses a reduction ratio of 1/30. There is. Furthermore, these microfilm images are not only enlarged to approximately the original size, but also reduced-scale copies (reused-size copies or half-size copies) are often made. In this embodiment, in order to respond to the variety of enlarged copies described above, the microfilm exposure scan start position and scan end position can be automatically set by the enlargement copy magnification and copy paper selection operation. There is. As mentioned above, the exposure scan start position and the exposure scan end position of the microfilm 61 are automatically controlled by the selected enlargement copying magnification and the selected copy paper size, so there are three types in this embodiment. The enlarged copy magnifications are an extremely reasonable combination of enlarged copy magnifications not only for the purpose of obtaining an enlarged copy of the original size from the microfilm 61 on the aperture card, but also for the purpose of obtaining a scaled copy thereof. That is, for the purpose of obtaining an enlarged copy of the original size, enlarged copy magnifications of ^14.5x and ^20x are prepared, corresponding to the standard reduction ratios of 1/15 and 1/21.2 for photographing originals. To obtain a scaled copy (half-size copy), an enlarged copying magnification of 10x is required for a microfilm image with a reduction ratio of ^1/15 , and an enlarged copying magnification of ^14.5x is required for a microfilm image with a reduction ratio of 1/21.2. , and an enlarged copying magnification for a microfilm image with a reduction ratio of 1/30.
20 ^x are available, making it possible to obtain an enlarged copy that is approximately half the size of the original size copy. Before detailed explanation of the enlargement copying magnification and the adjustment of the exposure scanning start position of the microfilm 61 and the control method of the scanning end position according to the combination of the copy paper and the enlargement copying magnification in this embodiment, the microfilm image 64, the exposure slit section 28, and the slit control device are explained below. 23. The relationship among the enlargement copying magnification, the exposure scan start position, the scan end position, etc. will be explained. FIG. 3 shows the relationship between the aperture card 2 and the microfilm 61 attached to its rectangular window. The intersection point O between the approximate center line in the short side direction of the aperture card, that is, a straight line at a distance d (41.3 mm) from the top edge of the card, and the straight line at a distance c (40 mm) from the right edge in the long side direction is the aperture point. The micro film 6 is aligned with the center of the rectangular window of Your Card 2 and is attached to the rectangular window.
The center position of 1 is also pasted so as to coincide with point O. As shown in FIG. 4, the attached microfilm 61 has external dimensions of 35 mm in the short side direction a ₁ and 48 mm in the long side direction b ₁ , which corresponds to the shooting frame size when photographing the original, that is, a ₂ × b ₂ 63 has short side a ₂ of 32 mm and long side b ₂ of
The standard is 45mm. As for the maximum image area a ₃ ×b ₃ 64 on the microfilm, it is standard that the short side a ₃ is 30.4 mm and the long side b ₃ is 41 mm. Also, since most of the microfilms that are attached to aperture cards and enlarged and copied as necessary are negative films, the inside of the photographic frame size a ₂ × b ₂ 63 on the microfilm mentioned above is from the illumination device 4. It has such a density that almost no irradiation light passes through it, and only the image area corresponding to the image area of the document passes the irradiation light. FIG. 4 shows an example of a microfilm 61 attached to an aperture card. For example, the range shown by T ₂ × Y ₂ 65, T ₃ × Y ₃ 66, and T ₄ × Y ₄ 67 is the image range when an A2, A3, or A4 size document is photographed at a reduction ratio of 1/15. If so, the dimensions are 28mm x 39.6mm, 19.8mm x 28mm, 14mm x
It becomes 19.8mm. Figure 8 shows the above-mentioned microfilm 61 at 14.5 ^x
FIG. 3 is a schematic diagram showing the relationship between an enlarged projected image of a microfilm image 64 onto the photosensitive drum 31 at the exposure scanning start point, an exposure slit unit 28, and a slit control device 23 when enlarging and copying a microfilm image 64; In FIG. 8, X7 is the exposure start point on the photoreceptor drum 31, and the light shielding edge 29a protruding into the projection light beam 22 of the upper slit plate 29 provided close to the surface of the photoreceptor drum 31 allows this point to be exposed. The projection light beam outside the point X7 is blocked so that it does not reach the photosensitive drum 31. The position on the microfilm corresponding to point X7 is indicated by S7, and this S
7 becomes the exposure start point of the microfilm image 64. Further, the slit control device 23 provided near the photoreceptor drum 31 has a blade 25 for a projection magnification of ^14.5x protruding into the projection light beam 22.
5, the point X on the photoreceptor drum 31
The projection light flux outside of 8 is controlled so as not to reach the photosensitive drum 31. Point X8 on the photosensitive drum 31 is the photosensitive drum 3 when the projection magnification is ^14.5x .
1, and this position corresponds to point S8 on the microfilm 61 at the time of starting the exposure scan. Area a ₃ on the microfilm 61 shown in FIG.
For example, convert an A1 size document to 1/21.2, or A2
This corresponds to the length of one side of the maximum image area when photographing a 1/15th size original, and the length in each case is 28 mm. Further, area _a2 corresponds to one side of the photographing frame size, and its length is 32 mm. Therefore, point S
The part from 7 to point S9 is microfilm 61
is outside the image area of the illumination device 4 (second
(Fig.) does not pass the irradiated light. Furthermore, although the microfilm 61 is positioned at the position shown in FIG. 8 by a registration adjustment device, which will be described later, before the start of exposure scanning, even if the light source lamp 5 of the illumination device 4 is energized and turned on before then,
Since the shutter 19 (FIGS. 2 and 14) is in a closed state so as to block the projection light beam 22 from the projection lens 8, the light emitted from the illumination device 4 does not reach the photoreceptor drum 31. As will be described later, the copy paper to be selected and used is controlled via a delay circuit from a signal to start feeding from the paper feeder 42 so that the exposure scanning movement of the microfilm 61 and the opening of the shutter 19 are started simultaneously. Therefore, the photosensitive drum 31 is not irradiated with light due to exposure other than the microfilm image area _a3 , so there is no toner adhesion due to the developing process, and there is no black band-shaped area other than the enlarged image of the microfilm image 64 on the copy paper. This eliminates the possibility of contamination of the photoreceptor drum 31, and also prevents the formation of band-like toner adhesion on the photoreceptor drum 31, which would place an extra load on the cleaning device 36. FIG. 9 is a similar diagram showing the relationship between the enlarged projected image on the photosensitive drum 31 at the position where the microfilm 61 shown in FIG. FIG. At the end of the exposure scan, as shown in FIG. 9, the lower end S10 of the image area _a3 of the microfilm
is scanned to position S8 in FIG. 8, and as will be described later, the drive for the scanning movement is interrupted via a delay circuit from an activation signal for the cutter 50 that cuts the selected copy sheet into a predetermined length. At the same time, the shutter 19, which blocks the projection light beam 22, rotates to the closed position and blocks exposure to the photoreceptor drum 31. At this point, as shown in FIG. 9, the part that does not pass the irradiation light from the illumination device 4, that is, the lower end of the photographic frame size _a2 is at the position S11,
Predetermined exposure areas X7 to X1 on the photosensitive drum 31
No irradiation light is projected that would cause toner to adhere to the zero. An example of specific dimensions that satisfy the above conditions is that the microfilm image area a ₃ is 28 mm, the shooting frame size a ₂ is 32 mm, and the enlargement projection magnification is
^14.5x , the exposure areas X7 to X8 of the photosensitive drum 31 are determined as follows. (32 mm - 28 mm) ÷ 2 x 14.5 = 29 mm That is, the exposure areas X7 to X8 only need to be 29 mm or less. If the microfilm image area _a3 has the aforementioned maximum image area size of 30.4 mm, the exposure areas X7 to X8 are similarly calculated to be 11.6 mm or less. In this embodiment, as described above, when the upper end of the microfilm image area a ₃ in the exposure scanning direction is at the exposure scanning start position, troubles due to exposure of parts other than the microfilm image area to the photoreceptor drum 31 are avoided. In order to prevent this, as shown in FIG. 8, a position X7 on the photoreceptor drum 31 corresponding to one end S7 on the exposure scanning start side of the microfilm image area is set as the exposure start point on the photoreceptor drum 31, as shown in FIG. When the exposure end point on the photoreceptor drum 31 is set to the position X10 on the photoreceptor drum 31 corresponding to the end S10 on the exposure scan end side of the microfilm image area of , the one end S9 of the photographing frame size _a2 in FIG. A point X9 on the photoreceptor drum 31 corresponding to is located outside the exposure end point X8 of the photoreceptor drum 31 regulated by the slit control device 23, and similarly, the point X9 on the photoreceptor drum ₃₁ corresponding to End S1
The point X11 on the photosensitive drum 31 corresponding to 1 is located outside the exposure start point (X7) of the exposure drum 31, which is regulated by the light-shielding edge 29a on the exposure scanning start side of the exposure slit section 28. It has means for regulating at least the size of the exposure area with respect to the body drum 31 in accordance with the enlargement projection magnification. ^FIG . 10 is a schematic diagram showing the relationship between the enlarged projected image of the microfilm image 64 onto the photosensitive drum 31 at the exposure scanning start position, the exposure slit section 28, and the slit control device 23 when the enlarged copying magnification is 10x. It is. In this case as well, the exposure start point X1 on the photosensitive drum 31 is at the same position as in the case of ^14.5x described above. Therefore, the exposure start point on the microfilm 61 corresponding to the point X1 on the photosensitive drum 31, that is, one end S1 of the microfilm image area _a3 ,
With respect to the optical axis position S ₀ -X ₀ of , it is located below the exposure scan start point S7 at ^14.5x described above. Therefore, at the time of starting the exposure scan of the upper end S3 of the photographing frame size area _a2 of the microfilm 61,
The corresponding point _X3 on the photosensitive drum 31 is
The irradiation light that is closer to _the optical axis position S ₀ −X ₀ than the similar point X ₉ in FIG. The cleaning device 36 (second
(see figure). In this embodiment, in order to prevent the above-mentioned inconvenience, a slit control device 23 is provided which acts to block a part of the projection light beam 22, and the enlargement copying magnification is 10 ^x .
Blades 24, 25, and 26 having shapes corresponding to 14.5 ^x and 20 ^x are installed radially on the rotating shaft 27, and are rotated in the direction of the arrow in FIG. 10 in response to an operation signal from the copy magnification selection key 542. is driven and positioned at a predetermined position. FIG. 10 shows a state in which the blade 24 for a copying magnification of ^10.times. is positioned so as to block a portion of the projection light beam 22. In this state, the projected image of the upper end _S3 of the photographing frame size _a2 on the microfilm is blocked by the blade 24 for a magnification of ^10x ,
The part on the microfilm 61 from _S2 to the outside, that is, the part from _S2 in the photographic frame size _a2 to the upper end _S3 of the photographic frame size _a2 , not only does not transmit the irradiation light, but also transmits the irradiation light. The projection light beam also does not reach the photosensitive drum 31 due to the shielding of the blade 24. Furthermore, the outer part of the shooting frame size _A2 ,
That is, the portion from the point S ₃ to the edge S ₄ of the microfilm 61 passes the irradiated light from the illumination device 4, but the projected light beam is blocked by the blade 24 and does not reach the photosensitive drum 31. Therefore, it is possible to prevent the inconvenience of toner adhering to the photosensitive drum 31 as described above in areas other than the enlarged image of the microfilm image 64. In this case as well, as in the case of the enlarged copying magnification of 14.5 ^x , when position X ₁ on the photosensitive drum 31 corresponding to the upper end S ₁ of the microfilm image area is set as the exposure start point of the photosensitive drum 31, The exposure end point S ₂ on the microfilm 61 corresponding to the exposure end point X ₂ on the body drum 31 is the microfilm 6
The exposure area on the photoreceptor drum ₃₁ is regulated in accordance with the enlargement projection magnification by the blade 24 of the slit control device 23, which blocks a part of the projection light beam 22 so that the photographic frame size is within the photographic frame size a2 of 1. are doing. An example of specific dimensions that satisfy the above conditions is that the microfilm image area _a3 is 28 mm, the photographing frame size _a2 is 32 mm, and the enlargement projection magnification is ^10x . The exposure areas X ₁ to X ₂ are determined as follows. (32mm−28mm)÷2×10=20mm In other words, the exposure areas X ₁ to X ₂ only need to be 20 mm or less.
If the microfilm image area _a3 has a maximum image area size of 30.4 mm as described above, the exposed areas _X1 to _X2 will similarly be 8 mm or less. FIG. 11 shows the microfilm 61 in FIG.
FIG. 3 is a schematic diagram showing the relationship between the enlarged projected image on the photosensitive drum 31, the exposure slit section 28, and the slit control device 23 at a position where the exposure scanning end position has been scanned. In this case as well, as in the case of the enlarged copying magnification of ^14.5x , at the end of the exposure scan, the lower end _S5 of the image area _a3 of the microfilm is at the point _S2 in FIG. 10, as shown in FIG. The shutter 19 cuts off the projection light beam 22 at the same time when the driving of the scanning movement is cut off via a delay circuit in response to an activation signal of the cutter 50 which is scanned to a position and cuts the selected copy paper into a predetermined length.
rotates to the closed position to cut off exposure to the photoreceptor drum 31. At this point, as shown in FIG. 11, the corresponding position on the photoreceptor drum 31 corresponding to the part that does not pass the irradiation light from the illumination device 4, that is, the lower end S6 of the photographing frame size _a2 , is X6, and the corresponding position on the photosensitive drum 31 is X6. Since the light flux passing outside the frame size a ₂ is not dropped onto the photoreceptor drum 31 at all, the predetermined exposure areas X1 to X of the photoreceptor drum 31 are
No irradiation light that would cause toner to adhere to the surface of the image forming apparatus 5 is projected. In the present invention, the aperture cards 2 are automatically transferred sequentially from the card hopper 82 to the carriage 1.
In addition to the function of positioning the aperture card 2 to be fed to the cartridge 111 and performing exposure scanning in the direction of its short side, the aperture card 2 is manually inserted and loaded into the carriage 111 so that its long side is in the same direction as the exposure scanning direction. It has a positioning function, and by using 594 mm wide roll paper as the copy paper, it is possible to easily obtain enlarged copies of A1 size, that is, 594 mm wide x 841 mm long. Enlarged projection magnification
^20x , and the length of the copy paper is also set to be cut to 841 mm. In this case as well, the aforementioned enlarged copy magnification
As in the case of ^14.5x , toner is prevented from adhering to a portion of the photosensitive drum 31 other than the enlarged image area due to enlarged projection outside the microfilm image area 64. ^FIG . 12 is a schematic diagram showing the relationship between the enlarged projected image of the microfilm image 64 onto the photosensitive drum 31 at the exposure scanning start position, the exposure slit section 28, and the slit control device 23 when the enlarged copying magnification is 20x. FIG. 13 shows the relationship between the enlarged projected image on the photosensitive drum 31, the exposure slit section 28, and the slit control device 23 at the position where the microfilm 61 shown in FIG. 12 has been scanned and moved to the exposure scan end position. FIG. In FIG. 12, the exposure start point X15 on the photosensitive drum 31 is at the same position as at ^14.5x described above. Therefore, the exposure start point on the microfilm 61 corresponding to the point X15 on the photoreceptor drum 31
S ₁₅ is the image area a ₃ on the microfilm in combination of enlargement projection magnification 20 ^x and copy paper size A1
A point _{S16 on the microfilm 61, which corresponds to one end and corresponds to the exposure end point X16 on the photosensitive drum 31 due to light shielding by the blade 26 of the slit control device 23 selected and set for a magnification of 20x} ^, is the shooting frame size. By being within the area _a2 , toner does not adhere to the photoreceptor drum 31 due to exposure of areas other than the microfilm image area _a3 , as described above.
In addition, as shown in Figure 13, the enlargement projection magnification
Due to the light shielding effect of the ^20x blade 26 of the ^slit control device 23, which operates in conjunction with the switching to 20x, the photoreceptor drum 31 is protected even at the exposure scan end position.
As described above, the shutter 19 is rotated to the closed position and blocks the projection light beam 22 while the portion of the microfilm 61 outside the shooting frame size _a2 is not exposed within the exposure area X15 to X18 of the photoreceptor. Toner does not adhere to the drum 31 due to enlarged projection of images other than the microfilm image. An example of specific dimensions that satisfy the above conditions is that the microfilm image area _a3 is 39.6 mm, the photographic frame size _a2 is 45 mm, and the enlarged projection magnification is ^20x . The exposure area X15 to X16 on 31 is the same as above (45mm-
39.6mm)÷2×20=54mm. That is, the exposure areas X15 to X16 only need to be 54 mm or less.
Also, if the maximum image area size is 41mm, do the same.
It will be less than 40mm. As described above, the microfilm 6 in this embodiment

The relationship between the blades 24, 25, 26, the enlargement copy magnification, the exposure scan start position, the exposure scan end position, the illumination device 4, the shutter 19, and the exposure to the photoreceptor drum 31 has been explained. The relationship with the copy paper onto which the enlarged image on the drum 31 is transferred will be specifically explained. As shown in FIG. 2, the copying apparatus 47 in this embodiment uses roll-shaped copy sheets 43, 44, and 45, which are mounted on a paper feeder 42 in three stages. The copy paper 43 is, for example, 297 mm wide, the copy paper 44 is, for example, 420 mm wide, and the copy paper 45 is, for example, 594 mm wide. When A4 size copy paper is selected, the copy paper 43 is fed to have a length of 210 mm. , When A3 size copy paper is selected, feed the copy paper 44 and adjust its length to 297 mm. When A2 size copy paper is selected, feed the copy paper 45 and adjust its length. When copy paper of 420 mm or A1 size is selected, the copy paper 45 is fed, and the cutter 50 is operated at a predetermined timing to cut the roll of copy paper to a length of 841 mm. Also,
Depending on the conditions of the microfilm image 64, the width
It is also possible to use a 210 mm roll copy paper, and the cutting length is also set to 297 mm. The above-mentioned copy paper is fed, and the photosensitive drum 31
The relationship between the copy paper and the enlarged image when the enlarged image of the above microfilm image is transferred by the transfer charging device 34 will be briefly explained. For example, when ^14.5x is selected as the enlargement copy magnification and A2 size is selected as the copy paper, the microfilm 61 held at a predetermined position in the carriage 111 is moved by the operation of the registration adjustment device 110, which will be described later. Microfilm image 64
is moved to a predetermined exposure scanning start position.
8, 49, and 52 rotate to feed the copy paper 45, and the leading edge of the copy paper 45 is rotated by the cutter 50, which is activated by a signal that activates the detection element 51 at a predetermined timing by a counting device and a comparator circuit (not shown). , the copy paper 45 is 420 mm from its leading edge.
Cut into lengths of mm. Then, the transfer charging device 3
4, from the leading edge of the copy paper to the photosensitive drum 3.
1. The contact point between the leading edge of the copy paper and the photosensitive drum 31 is the upper edge S of the microfilm image 64 in FIG.
Since the scanning start point of the microfilm image 64 is controlled in relation to the copy paper feeding start point so as to coincide with the enlarged projection position X7 on the photosensitive drum 31 of No. 7, the microfilm image 64
The enlarged image of the leading edge of the image does not protrude from the copy paper. Also, the enlarged projection position X1 on the photosensitive drum 31 of the lower end S10 of the microfilm image 64 in FIG.
Similarly, the microfilm image 64 is placed on the photoreceptor drum 3 so that it is aligned with the trailing edge of the copy paper.
Since the exposure scanning movement is controlled in relation to the moving speed of the circumferential surface of No. 1 and the enlargement projection magnification,
The enlarged image at the rear end of the microfilm image 64 also does not protrude from the copy paper. That is, this means that the exposure scan end signal of the microfilm image 64 is generated when the cutter 50 of the copy paper 45 generates a predetermined length cutting signal, that is, the enlarged projection of the lower end _S10 of the microfilm image 64 onto the photosensitive drum 31. From the time when the position reaches X ₇ , the signal is emitted after being delayed by the timer circuit by the time required to move it to X ₁₀ , that is, by the time corresponding to the exposure area on the photosensitive drum 31 corresponding to the projection magnification. It is from. Since the enlarged image of the microfilm image on the photosensitive drum 31 and the copy paper to which it is transferred are controlled in the above-described relationship, enlarged copies can be made with the selected enlargement copy magnification and the selected copy paper. The maximum image size on microfilm is determined. Therefore, the exposure scan range of the microfilm image, that is, the exposure scan start position and the exposure scan end position are automatically controlled. Table 1 shows specific combinations of enlargement copying magnifications and copy paper selections, and corresponding document sizes and photographic reduction ratios of microfilm images in this embodiment.

Furthermore, when copying roll paper is not loaded in any of the upper, middle, and lower stages of the paper feeder 42, or there is no roll paper loaded, the position indication is displayed on the display 525b,
This is clearly indicated by blinking either 525c or 525d. An arrow 524 is an indicator light indicating that the above-mentioned abnormal condition exists, and it blinks until the abnormality is corrected. The display 523 blinks until the temperature inside the fixing device 38 reaches a predetermined set temperature, and turns off when the temperature reaches the predetermined set temperature. Also this display 5
The copy start switch 561 shown in FIG. 40 is controlled so as not to operate until 23 goes out. In FIG. 38, the display 533 consists of a left and right two-digit digital display, and when enlarging multiple copies from the same aperture card, the number of copies can be set from 1 to 99 using a numeric keypad type number key 534. The set value is displayed on a two-digit digital display 533a. When correcting a wrong number, clear the number using the clear key 534a and perform the operation again. This device has a counter 5 that counts at the end of exposure.

The contents are not cleared until they pass through the device 38 even if there is a momentary interruption or power outage. If a jam occurs during enlarged copying, the contents of the counter 533c are transferred to the counter 533b at that moment and displayed on the display 533b. counter 533
For c, the number of enlarged copies that have passed through the fixing device (usable) is considered valid, and the rest are considered as unfixed, untransferred, etc. If there is a momentary interruption or power outage, the contents of the set counter 533c will be displayed 533 after recovery.

The number of times the same aperture card has been exposed and scanned is displayed according to the exposure scan end signal of 1, and display 5
The repeat signal is canceled by a signal in which 33a and 533b match. The contents of the counter 533a to be displayed will not be cleared even if there is a momentary power outage or power outage unless the enlarged copying work is completed.
A circuit (not shown) that determines whether the numeric keypad has been pressed clears the number set before the numeric key was pressed, and sets the number that was pressed. Furthermore, after the copying operation is completed, the clear key 534a can be used immediately to clear the set number. If you wish to interrupt copying from the aperture card for some reason while copying in repeat mode, the repeat signal is canceled by the operation signal of the stop key 535 and the exposure scan end signal that follows after the signal is generated, and the aperture card is Your card is ejected to the card stacker, and feeding of subsequent aperture cards is also interrupted. copy counter 531
is a 4-digit mechanical counter that is activated by a signal from a switch 59 (see Figure 2) that detects when an enlarged copy from an aperture card has passed through the fixing device 38, and can be reset to 0 using a reset button 531a. It's getting old. The card counter 532 is activated by a signal that activates the fourth detection element 157 when the aperture card that has completed exposure scanning is ejected by the card ejection device 163 (see FIG. 16).
The number of enlarged aperture cards is displayed and can be reset to zero by operating a reset button 532a. In FIG. 39, card feed selection key 541
The aperture card loaded in the card hopper 82 (see FIGS. 1 and 14) is transferred to one aperture card in the card hopper 82 by one operation signal of the copy start switch 561 shown in FIG. The card is fed to the carriage 111, exposed and scanned, and ejected, and the subsequent aperture card is
When selecting a mode in which only one card is fed to the carriage 111 by a new operation signal from the copy start switch 561, the one-sheet feed key 541b is pressed, and by a single operation signal from the copy start switch 561, the card hopper 82 is fed. When selecting a mode in which the subsequent aperture cards are sequentially fed to the carriage 111 and exposed and scanned after exposure scanning and ejection of the preceding aperture card, press the continuous feed keys 541a respectively. All you have to do is select. The selected key is displayed by lighting. When a plurality of aperture cards are loaded in the card hopper 82 and the continuous feed key 541a is selected, the fifth detection element 8 in FIG.

In addition, if you wish to interrupt copying in continuous feeding mode for some reason, press the stop key 535 mentioned above.
The feeding of the subsequent aperture card is interrupted by the operation signal and the exposure scan end signal that follows after this signal is generated, and the card feeding selection key 541 is automatically switched to the single card feeding mode, and the continuous feeding key 541 is switched to the single card feeding mode. 541a goes out. Furthermore, when the main switch 521 is turned on, the single-sheet feeding mode is automatically selected with priority, and when no aperture card is loaded in the card hopper 82, the continuous feeding mode is selected as the continuous feeding mode.
It seems that it is not working. The copy magnification selection key 542 is a ^10x key 542
Consists of a, 542b for 14.5 ^x , 542c for 20 ^x ,
The aforementioned projection magnification switching device 20

When the ^20x key 542c is selected, the carriage 111 is moved to a predetermined position for vertical card loading and stopped, and the card feed selection key 541 is turned off, as described above.
When changing the magnification from ^20x to another magnification, if the aperture card is still loaded in the carriage 111 in the vertical position, the projection magnification cannot be changed even if the other magnification selection keys 542a and 542b are operated. The vertical card detection element 509 is activated by the aperture card so that the device 200 and the slit control device 23 are not activated, and after the aperture card is removed from the carriage 111, it is possible to switch to another magnification. . Further, when the magnification is selected to be ^20x , the control circuit is operated so that the aperture card is not fed from the card hopper 82. The copy paper selection key 543 is a key for selecting which of the three roll papers loaded in the upper, middle, and lower stages of the paper feeder 42 is to be fed.
3a, middle roll key 543b, lower roll key 54
Consists of 3c. The paper type display 544, which displays whether the upper, middle, and lower roll paper is plain paper or tracing paper, displays the paper type with pictograms,
Plain paper is displayed with a solid line pictogram 544a, and tracing paper is displayed with a broken line pictogram 544b, which correspond to the top, middle, and bottom roll paper. The paper type is determined by the roll paper detection element 5 in Figure 2.
6, 56a, 56b, 56c are for the upper roll, 5
3, 53a, 53b, 53c are used for the middle roll, and 54, 54a, 54b, 54c are used for the lower roll, and the roll paper width is 210 mm, 297 mm, respectively.
They are arranged to correspond to 420mm and 594mm. The signal from this roll paper detection element is displayed on the copy paper size display 545 to display the copy size that can be enlarged and copied on the roll paper corresponding to the loaded roll paper.
5a, and when only the roll paper detection elements 56, 53, and 54 of each of the upper, middle, and lower rolls detect the presence of roll paper, the 210 mm width roll paper is detected. It emits a loaded signal and the A4 vertical (A4T) indicator light lights up. In addition, roll paper detection elements 56 and 56a, 53
When 53a, 54 and 54a respectively detect the presence of roll paper, they will issue a signal indicating that a 297mm wide roll paper is loaded, and the A4 landscape (A4Y)
The indicator light lights up. Furthermore, roll paper detection elements 56, 56a, 5
6b, 53, 53a, 53b, 54, 54
When each of a and 54b detects that roll paper is present, it issues a signal indicating that a 420 mm wide roll paper is loaded, and the A2 horizontal (A2Y) display lights up. Similarly, 54, 54a, 54b.5 for the upper roll
4c, for medium rolls 53, 53a, 53b, 53
c, 54, 54a, 54b, 54c for the lower roll
When each of the detection elements detects the presence of roll paper, it emits a signal indicating that a 594 mm wide roll paper is loaded, and the A1 vertical (A1T) indicator light lights up. When the roll paper is not loaded or is empty, the indicator light 525b, 525c, or 525d of the roll position in the position display section 525 in FIG. 37 lights up, as described above. In this device, the registration adjustment of the enlarged projected image from the microfilm is automatically performed by a combination of the enlargement copying magnification and the copy paper size, and the imaging reduction ratio on the microfilm is adjusted in accordance with the document size. Since this has been standardized, the control circuit is configured to prohibit combinations of enlargement magnification and copy paper that would cause the enlarged image to protrude from the copy paper. In other words, when copying magnification is ^20x , the copy paper size is A2 landscape and A1 portrait; when copying magnification is ^14.5x , it is A1 portrait; and when copying magnification is ^20x , it is A2 landscape, A3 landscape, A4 landscape, and A4 portrait. If you accidentally select an inappropriate copying magnification or copying paper size, the copying paper size indicator light for the relevant roll will blink, indicating that the combination is prohibited, and copying will not be possible. The start switch 561 (see FIG. 40) is also controlled so as not to operate. For example, the upper roll 43 (see Figure 2) has a diameter of 297 mm.
When the middle roll 44 is loaded with a 420 mm wide roll paper, and the bottom roll 45 is loaded with a 594 mm wide roll paper, the copy paper size display will be (A4Y), (A3Y), (A2Y), respectively. is lit. At this time, when a copy magnification of ^10x is selected, the A2 horizontal (A2Y) indicator light of the relevant roll flashes depending on the lower roll selection, and when a copy magnification of ^14.5x is selected, the copy paper is When the size indicator does not blink and the copy magnification is ^20x ,
Depending on the selection of top roll and middle roll, each A4
The copy paper size display for landscape, (A4Y) and A3 landscape (A3Y) blinks. Also, at this time, by selecting the lower roll, the copy size of the roll concerned will be displayed as A2.
Horizontal (A2Y) turns off and A1 vertical (A1T) lights up. The copy paper selection key lights up to indicate that only one of the top, middle, and bottom paper sheets has been selected by the selection operation. In the middle operation panel 540, an operation section for adjusting the amount of exposure to the photoreceptor drum 31 by enlarged projection from the microfilm and a display section are further arranged in the middle thereof. The exposure amount adjustment knob 547 controls the voltage applied to the light source lamp 5 for exposure, and by rotating clockwise, the voltage applied to the light source lamp 5 increases.
Therefore, the density of the copied image is increased. Rotation counterclockwise lowers the applied voltage and therefore lowers the image density. The exposure amount display 546 is composed of a three-digit display element, and is digitally displayed in numbers from 1.0 to 10.0 in response to changes in the voltage applied to the light source lamp 5 from 8 volts to 24 volts. Then, the voltage applied to the light source lamp 5 at this time is set to 14 volts, with the standard density of the microfilm, that is, the appropriate exposure amount when enlarging and copying a microfilm whose background density is 1.0, as the standard. The value on the exposure amount display 546 at this time is
4.5, and the voltage applied to the light source lamp 5 corresponding to the display around this value, that is, from 3 to 6, is:
It is controlled so that the voltage changes almost linearly from 12.5 volts to 15.5 volts. This makes it easy to fine-tune the voltage applied to the light source lamp 5 so that good enlarged copies can always be obtained in response to slight density changes in commonly used microfilm, and the appropriate exposure amount can always be maintained. This makes it easy to feed the body drum 31. FIG. 42 shows a circuit that controls the voltage applied to the light source lamp 5 and the numerical value of the exposure amount display 546. The exposure adjustment knob 547 includes variable resistors 631a and 63.
Three linked variable resistors 63 of 1b and 631c
1 is directly connected. The variable resistor 631a has an inverse characteristic where the resistance value decreases when rotated clockwise, and the variable resistor 631b has a positive characteristic where the resistance value increases when rotated clockwise. By combining 631b and 631b, an opposite characteristic is obtained in which the resistance value decreases when the exposure adjustment knob 547 is rotated clockwise. The lamp regulator 632 is a power source for applying voltage to the light source lamp 5, and controls the applied voltage by feeding back the applied voltage to the lamp regulator 632. lamp regulator 632
When the feedback voltage is small, the voltage applied to the light source lamp 5 becomes small, and when the feedback voltage is large, the voltage applied to the light source lamp 5 becomes small.
The voltage applied to is increasing. The feedback voltage to the lamp regulator 632 is from the light source lamp 5 to the variable resistors VR3, VR4, 6.
31a and 631b, the exposure amount adjustment knob 54 is supplied to the lamp regulator 632.
When 7 is rotated clockwise, these resistance values become larger, so that the feedback voltage becomes smaller and the voltage applied to the light source lamp 5 becomes smaller. In addition, when rotating counterclockwise, the resistance value decreases, so the feedback voltage increases, and the light source lamp 5
The applied voltage increases. Variable resistor VR3
adjusts the feedback voltage to the lamp regulator 632 to control the voltage applied to the light source lamp 5 when the exposure adjustment knob 547 is fully rotated clockwise.
This is a variable resistor for adjusting to 24 volts. The variable resistor VR4 adjusts the feedback voltage to the lamp regulator 632 so that the voltage applied to the light source lamp 5 is 8 volts when the exposure adjustment knob 547 is fully rotated counterclockwise. This is a variable resistor for adjustment. In FIGS. 39 and 42, the exposure amount display 546 is displayed by a panel meter 633, and the variable resistor VR1, 631
By supplying voltage to the panel meter 633 via VR2, the numerical value changes. The variable resistor 631c has a negative characteristic in which the resistance value decreases when rotated clockwise. Variable resistor VR1
is a variable resistor for adjustment so that the voltage supplied to the panel meter 633 is 10 volts, that is, the value on the exposure display 546 is 10.0 when the exposure adjustment knob 547 is fully rotated clockwise. . The variable resistor VR2 is a variable resistor for adjusting the voltage supplied to the panel meter 633 so that when the exposure amount adjustment knob 547 is fully rotated counterclockwise, the value on the exposure amount display 546 becomes 1 volt, that is, the value on the exposure amount display 546 becomes 1.0. It is a resistor. Each time the exposure amount adjustment knob 547 is rotated, the resistance value of the variable resistor 631c changes, so the voltage supplied to the panel meter 633 changes, so the value on the exposure amount display 546 changes from 1.0 to 10.0.
are displayed digitally. That is, since the variable resistors 631a, 631b, and 631c are linked to the exposure amount adjustment knob 547, the numerical value on the exposure amount display 546 and the voltage applied to the light source lamp 4 correspond to each other. FIG. 43 shows the numerical value of the exposure amount display 546 and the light source lamp 5 obtained by the lamp regulator 632.
This is a graph showing the relationship between the voltage applied to the light source lamp 5 and the voltage applied to the light source lamp 5 from 12.5 volts to 15.5 volts by combining variable resistors 631a and 631b.
It is now possible to control the applied voltage almost linearly. The voltage applied to the light source lamp 5 is from 12.5 volts.
It is linearly controlled up to 15.5 volts, and the value on the exposure display 546 at this time is
Since the display is from 3.0 to 6.0, the voltage applied to the light source lamp 5 is 14 volts, and by rotating the exposure adjustment knob 547 around the value 4.5 on the exposure display 546, the exposure can be adjusted. Amount display 54
Corresponding to increasing or decreasing the value of 6 by 0.1, the voltage applied to the light source lamp 5 increases or decreases by 0.1 volt, so
Fine adjustments can be easily made in response to slight density changes in commonly used microfilms. In addition, when it is desired to change the range in which the value of the exposure amount display 546 and the range in which the voltage applied to the light source lamp 5 changes, that is, the value obtained by changing the value of the exposure amount display 546 and the lamp regulator 632 shown in FIG. If you want to change the relationship between the voltage applied to the light source lamp 5 and the voltage applied to the light source lamp 5, use variable resistors VR1, VR2,
It can be easily changed by adjusting VR3 and VR4. FIG. 44 is a graph showing the relationship between the value of the exposure amount display 546 and the voltage applied to the light source lamp 5, in which the voltage applied to the light source lamp 5 is corrected by adjusting the variable resistors VR3 and VR4. Line b in FIG. 44 is a reference graph and is the same as in FIG. 43. Line a in FIG. 44 shows that when the exposure amount is low due to variations in the light source lamp 5, the variable resistor VR
3. This is a graph obtained by correcting the voltage applied to the light source lamp 5 using VR4 and shifting the graph of line b in FIG. 44. Line c in FIG. 44 indicates that when the exposure amount is high due to variations in the light source lamp, the variable resistor VR3,
This is a graph obtained by correcting the voltage applied to the light source lamp 5 using VR4 and shifting the graph of line b in FIG. 44. Returning to FIG. 39, the lower part of the middle operation panel 540 includes a fixing temperature display 548, a paper registration switch key 549, a cut length switch key 550, a paper discharge direction switch key 551, and an alarm buzzer key 5.
52 are arranged. Display 549a, 550
a, 551a, 552a are for each corresponding key.
Turns the light on and off by turning it on and off. The fixing temperature display 548 is displayed by selection keys 571a and 5 of the fixing temperature selection key 571 (see FIG. 41) arranged on the right operation panel, ranging from low to high temperature.
In response to the selection operation of 71b, 571c, 571d, indicator lights 548a, 548b, 548c, 54
8d lights up. After turning on the main switch 521, when the fusing temperature selection key 571 is selected and switched, the indicator light corresponding to the selection key on the fusing temperature display 548 is displayed until a predetermined part of the fusing device 38 reaches the selected temperature. will flash and turn on when the signal reaches a predetermined temperature. By operating the paper registration switch key 549, the indicator light 549a lights up, which delays the start timing of the scanning movement of the carriage 111, which starts the scanning drive via the delay circuit in response to the copy paper feeding start signal, and enlarges from the microfilm. By shifting the copy image by a predetermined amount toward the rear end of the copy paper, a larger margin than usual can be created at the leading edge of the copy paper. The predetermined amount for creating the margin can be adjusted by a timer circuit that delays the start of scanning movement of the carriage 111. The cut length switching key 550 is controlled to make the cut length of the copy sheet longer than the standard size by a predetermined amount in response to an operation signal thereof. That is, as described above, in this apparatus, the selected roll paper is fed, and the pulse signal generated in synchronization with the feeding of the roll paper is counted from the signal that activates the detection element 51 shown in FIG. The cutter 50 is activated to cut the roll paper to a predetermined length in response to an activation signal from a comparator circuit that detects that the number of pulses has started and a predetermined number of pulses has been reached.
The operation signal 0 controls the circuit to delay the start of pulse signal counting mentioned above, so the cut length of the roll paper is the length corresponding to the predetermined number of pulses and the length corresponding to the delay time of the start of counting mentioned above. The length will be the sum of This counting start delay time can be adjusted by a timer circuit. This apparatus includes a fixing device 38 as shown in FIG.
There is a guide plate 575 for ejecting the copy paper to the rear of the apparatus before it is ejected to the paper ejection tray 41.
In response to the operation signal from 51, the guide plate 575 is rotated clockwise around the shaft 575a by the urging of a solenoid (not shown), and the leading end of the guide plate 575 enters the copy paper conveyance path, so that the copy paper is The paper sheets are guided by the guide plate 575 and discharged to the rear of the apparatus, and then stacked on a paper discharge tray (not shown). Needless to say, when the paper ejection direction switching key 551 is released, the copy paper is ejected to the paper ejection tray 41 at the front of the apparatus. This device is configured so that a large number of aperture cards are loaded into the card hopper 82 and predetermined enlarged copies are automatically continued one after another. There are many things. However, if the roll paper runs out during enlarged copying, or if some trouble occurs with the feeding and transportation of copy paper, aperture cards, etc., in order to prevent time loss due to machine stoppage, the operation is performed remotely from the machine. It is necessary to inform the person concerned of these situations.
Therefore, in addition to the visual display means using the lighting display as described above, this device also includes an acoustic display means using the auditory senses. That is, when this is turned ON by operating the alarm buzzer key 552, when the copy paper that is being selectively fed runs out, the aperture card feeding/transmission is activated when there is a jam in the copy paper feeding/conveying path. When a jam is ejected, when a predetermined number of copies have been copied from the last loaded aperture card, and when the paper feed device 4

When 32f turns on SW4, when the lower end 132e of the supporting arm turns on SW3, and when pressing piece 181 of pulley 171 turns on micro switch 180 or 180a, the buzzer sounds as shown in FIG. The operator who is away from the emitting device can be notified through the open window 552b, allowing the operator to take immediate action. Furthermore, when a predetermined number of copies have been made from the last loaded aperture card, the buzzer sound is interrupted by turning on the reset switch 564. On the table 58 of this device, as shown in FIG. 1, a table operation panel 560 is arranged below the above-mentioned lower operation panel 540. The details of the operation surface are as shown in FIG.
3a, an intermediate position jam detection display 563b, an end position jam detection display 563c, and a discharge position jam detection display 563d.
4 and a copy start switch 561 are arranged. If the aperture card fed from the card hopper 82 stops being fed on the feeding path 101 before reaching the first detection element 91 or does not reach the first detection element 91 within a predetermined time, , the aperture card feeding drive is stopped by the jam detection timer circuit, and the reset switch 5 is activated.

In the unlikely event that two aperture cards fed from the card hopper 82 overlap and are detected by the two-card detection rollers 86, 102 and the micro switch 87 is actuated, the aperture card feed will be stopped. The drive is stopped, and the card double feed detection display 563a, card jam display 562a, and reset switch 564 are lit. In this case as well, as described above, the manual knob 85b allows the separating roller 8 to

If the jam stops before reaching the first feeding roller 88, the intermediate position jam detection display 5 will be displayed.
63b, the reset switch 564 is displayed lit. In this case as well, when the aperture card is returned to the card hopper 82 by turning the manual knob 85b, the intermediate position jam detection display 563b is turned off, and the reset switch 564 is also turned off by the ON operation. The tip of the aperture card is the first detection element 91
Passing the first feeding roller 88, the second sensing element 10
If the machine stops before reaching 4, the intermediate position jam detection display 563b and reset switch 564
is displayed and lit. In this case, by turning on the reset switch 564, the aperture card is automatically placed in the card stacker 162 as described above.
is discharged, and the display also turns off. The aperture card is connected to the first sensing element 91 and the second sensing element 91.
When the card is stopped while straddling the detection element 104, the display lighting mode is the same as that described above, and the automatic ejection function is also activated.
The same applies when only the detection element 104 is activated and stopped. When the aperture card remains stopped at the position where both the second detection element 104 and the third detection element 97 are activated, the end position jam detection display 563c and the reset switch 564 are lit, and in this case as well, the automatic The ejection function automatically ejects the aperture card to the card stacker 162, and the display turns off. In addition, if an aperture card is left in the card ejection device 163 at a position where it can be detected by the fourth detection element 157, the ejection position jam detection display 5
63d and the reset switch 564 are displayed lit. In this case as well, turn on the reset switch 564.
In operation, the aperture card is ejected to the card stacker 162 and the display is also turned off in the same way as the operation by the initial clear signal described above. As shown in FIG. 15, it is already known that the aperture card positioned to be fed into the carriage 111 is moved to a predetermined exposure start position before the exposure starts, depending on the combination of the selected magnification and copy paper size. explained. In this case, the drive control of the pulse motor 136 that moves the carriage 111 does not work properly for some reason, and one of the support arms of the push-up member 132
The upper end 132f of 32d is the micro switch SW.
By pressing 4, the pulse motor 136
When the drive circuit is cut off and the movement of the push-up member 132 is stopped, the reset switch 564 is lit. When this happens, turn on the reset switch 564 to turn on the pulse motor 13.
6 is rotationally driven to move the push-up member 132 in the DN direction, and the carriage 111 also moves in the DN direction.As described above, the reference positioning device 116 is operated, and the ON signal of the switch SW ₁ turns on the pulse motor 136. The rotation drive is cut off, and the carriage 1
11 is also positioned at the reference position. However, for some reason, the carriage 11
1 does not move in the DN direction, only the push-up member 132 moves in the DN direction, and the lower end 132 of its support arm
If the rotational drive of the pulse motor 136 remains cut off by pressing the micro switch SW ₃ , the timer starts operating by turning on the reset switch 564 mentioned above. Due to the function of the circuit, if the ON signal of switch SW ₁ is not generated by pressing the carriage 111 within a predetermined time, the serviceman call display 562b is lit and the reset switch 56 is turned on.
4 also maintains the lighting display mode. Needless to say, after the trouble is repaired by the service person, the display will go out and the normal state will return. Referring to FIG. 17, the carriage 111 positioned at the exposure scan start position is scanned in the UP direction by a scan start signal. Regardless of the generation of the scanning movement end signal, the scanning movement drive is not cut off and the pressing piece 181
operates the micro switch 180,
In response to the ON signal of the micro switch 180, the control circuit operates to cut off the scanning movement drive of the carriage 111, and at the same time, the aperture card in the carriage 111 is also ejected to the card stacker 162 by the operation of the card ejection device 163, and the aperture card in the carriage 111 is ejected to the card stacker 162 by the operation of the card ejection device 163.
11 moves in the DN direction to the reference position. However, if the scanning movement drive of the carriage 111 is still not cut off due to a malfunction of this control circuit, the pressing piece 181 is pressed against the micro switch 180.
By pressing a and directly cutting off the energizing circuit of the electromagnetic clutch 322 (see FIG. 18),
The scanning movement of the carriage 111 is stopped, and at the same time, the electromagnetic brake 346 is energized and the carriage 111
When the reset switch 5 is held in the position of
64 is displayed lit. When this happens, turn on the reset switch 564.
Upon operation, the electromagnetic brake 346 is deenergized, and at the same time the eject motor 343 is rotationally driven for a predetermined period of time, the carriage 111 is moved to the reference position, and the switch of the reference positioning device 116 is turned on.
The reset switch 564 is turned off by the ON signal of SW ₁ . In this case as well, the aperture cards in the carriage 111 are ejected to the card stacker 162 by the operation of the card ejecting device 163, as described above. However, if for some reason the carriage 111 does not return to the reference position within a predetermined time after turning on the reset switch 564, the serviceman call indicator 562b lights up and the reset switch 564 does not turn off. After the trouble is repaired by the service person, the display will turn off and the device will return to normal condition. When the light source lamp 5 is on, the circuit is configured to detect the current flowing through the light source lamp 5 for a predetermined period of time from the exposure scanning movement start signal of the carriage 111, and in the unlikely event that the predetermined current is not flowing. When detected, the service man call display 562b lights up. In response to this detection signal, the aperture card in the carriage 111 is ejected from the carriage 111, which is driven to a predetermined scanning movement end position, to the card stacker 162 by the operation of the ejecting device 163.
1 is returned to the reference position and stopped, and the feeding of subsequent aperture cards is also interrupted. Disconnection of the light source lamp 5 or failure of the lighting circuit, etc.
If the cause of current not flowing through the light source lamp 5 is removed and repaired, the serviceman call display 526b returns to the off state. In addition, this device is provided with a temperature fuse near the light source lamp 5 in order to prevent the lighting device 4 from overheating due to failure of a light source lamp cooling fan (not shown).
It works to turn off the lighting circuit of the light source lamp 5.
In this case as well, the serviceman call 562b display lights up and the carriage 111 and
The aperture card in No. 1 operates in the same manner as described above. The copy start switch 561 has built-in indicator lights in two colors, red and green, and lights up in red when each part of this device detects that a problem has occurred in the normal copying operation as described above. Even if the copy start switch 561 is operated, no copying operation is performed. That is, Γ From the time when the heater of the fixing device 38 starts to be heated by electricity until it reaches a predetermined selected temperature, Γ When there is no roll paper in any stage of the paper feeder 42, Γ The roll in the stage where no roll paper is loaded Γ When a prohibited combination of enlarged copy magnification and copy paper size is selected, Γ When a jam occurs in the copy paper feed path, Γ When an aperture-your-card feed jam occurs , Γ When the aperture card feeding mode is one-sheet feeding mode, Γ When the aperture-card feeding mode is one-sheet feeding mode, the carriage 111 returns to the reference position after scanning movement from the start of aperture card feeding. When the aperture card feeding is in a continuous feeding mode, from the start of aperture card feeding to the end of scanning feed of the last aperture card, the carriage 111
Until it returns to the reference position, Γ When the push-up member 132 of the registration adjustment device 110 operates SW ₄ and stops, the push-up member 132 of the registration adjustment device 110 operates switch SW ₃ and stops. When Γ the pulley 171 that drives the carriage 111
When the machine stops at the position where the micro switch 180a is activated, Γ When the device's housing door, paper feed, developing, separation conveyance, fixing, separation claw, etc. are not set properly, etc., copying starts. The switch 561 lights up in red, and even if it is operated at this time, no new activation signal will be issued. When each part of this device is in a state where normal copying operations can be performed, the copy start switch 561 is lit in green. When an aperture card is loaded into the card hopper 82, the copy start switch 561 is operated. , a signal to start the enlarged copying operation is issued from the aperture card. In FIG. 41, the fixing temperature selection key 571
There are selection keys 571a, 571b, 571c, and 571d for selecting the temperature at which the toner transferred to the copy paper by the fixing device 38 is fused in four steps from high temperature to low temperature depending on the type of copy paper. The temperature range is selected when film or tracing paper is used as copy paper, and the high temperature range is selected when plain paper or thick copy paper is used. Fixing temperature selection keys 571a, 571
b, 571c, and 571d are each equipped with an indicator light, which is turned on and displayed by a selection operation. The key switch 573 prevents dew condensation on the surface of the photoreceptor drum 31 due to changes in the temperature and humidity of the atmosphere around the photoreceptor drum 31.
This is an ON/OFF switch for the heater that heats the photoreceptor drum 31, and is lockable to prevent the characteristics of the photoreceptor drum 31 from deteriorating due to careless ON/OFF operation. Display 572 indicates key switch 57
This is an indicator light that indicates whether 3 is ON or OFF. Next, various operations related to card feeding will be explained based on the flowcharts shown in FIGS. 45 and 46, the circuit examples shown in FIGS. 47 to 55, and FIG. 14. Aperture-your-card feeding In response to the operation signal of the copy start switch (see Fig. 40), a card feeding signal is sent to the electromagnetic clutch 85c, the control F/
It is input to the clock terminal of F1, F/F1 is set, and the output is sent to the electromagnetic clutch 8 by driver 1.
5c is energized and driven. At the same time, the card feeding signal is input to OR6-, the output of OR6 is input to the clock terminal of card drive control F/F2, F/F2 is set, and the outputs are sent to the drive motors by driver 2. 103, the driver 3 energizes the solenoid 90, and the driver 4 energizes the solenoid 96. Furthermore, the output of OR6 is OR4−
The output of OR4 is input to the clock terminal of F/F4 for controlling the opening and closing of the glass crimp plate.
F/F4 is set, and its output is energized and driven by the solenoid 141 by the driver 6, and the glass pressure bonding plate 9 is
3 and 93a are opened. The aperture cards in the card hopper 82 are sent out one by one in the direction of the feeding path 101 by the separation roller 85 which is rotated counterclockwise by the drive motor 103 and the electromagnetic clutch 85c. The aperture card has two detection rollers 86,1
02, and is further fed to the right by the first pinch roller 89 which is brought into contact with the first feeding roller 88 by the urging force of the solenoid 90. An electromagnetic clutch OFF timer is set in response to an activation signal generated when the tip of the fed aperture card passes through the first detection element 91. The setup time of the timer is such that the subsequent aperture card 2a is transferred from the card hopper 82 to the feeding path 101.
The electromagnetic clutch 85c is adjusted so that the electromagnetic clutch 85c is de-energized when the leading edge of the aperture card is in front of the two-sheet feed detection rollers 86, 102. When the electromagnetic clutch OFF timer is set up, its output is input to OR1-, and the output of OR1 resets the electromagnetic clutch control F/F1. As a result of the reset, the electromagnetic clutch 85c, which had been energized and driven by the driver 1, is de-energized. The aperture card is transferred to the second feeding roller 94
By energizing the solenoid 95, the second pinch roller 95 that comes into contact with the solenoid 95 further feeds the aperture card 2, and the tip of the aperture card 2 reaches the third detection element 97.
passes through and comes into contact with the card positioning lever 98,
A spring 98a provides a counterclockwise rotational habit;
Rotate the card positioning lever 98 clockwise. At this time, the tip of Aperture Your Card 2 is
The activation signal due to passing through the detection element 97 is
It is input to OR2-, and the output of OR2 resets the card drive control F/F2. Due to the reset, the drive motor 103, solenoid 90, and solenoid 96, which were energized and driven by the respective drivers 2, 3, and 4, are de-energized. As a result, the first feeding roller 88 and the second feeding roller 9
4 loses the ability to feed the aperture card, the card positioning lever 98 is pushed back counterclockwise, and the aperture card is positioned. The activation signal generated by passing through the third detection element 97 also sets the solenoid 104 and the OFF timer. The set time of the timer is the time from when an activation signal is generated when the tip of the aperture card passes the third detection element 97 until the aperture card is positioned. Once set up, its output is OR5-
The output of OR5 is used to control the opening/closing of the pressure plate.
Reset F4. Due to the reset,
Solenoid 14 that was energized and driven by driver 6
1 is cut off, and the space between the glass pressure bonding plates 93 and 93a is closed. The output of the above timer is solenoid 99
Also set the ON timer. The set time of the timer is the time until the glass pressure bonding plates 93, 93a are completely closed. When the solenoid 99 timer is set up, its output is input to OR8-, the output of OR8 is input to the clock terminal of solenoid 99 control F/F3, and F/F3 is set. The output is energized and driven by the driver 5, and the aperture card 2 is positioned. Jam detection system in card feeding There are various positions where cards can jam.
Each will be explained assuming various cases. If two or more Aperture Your Cards are fed at the same time, the Aperture Your Card 2 will be sent to the Card Hopper by the operation signal of the copy start switch (see Figure 40) and the card feed signal that has passed through a condition determination circuit (not shown). 82 and passes between the two detection rollers 86 and 102. However, if two or more aperture cards 2 are fed simultaneously, the next aperture card that overlaps with the aperture card 2 The detection roller 8b operates the detection signal micro switch 87 depending on the thickness of the card 2a. This detection signal is input to OR16- in FIG. 52, and the output of OR16 is input to the set terminal of jam detection F/F8, and F/F8 is set.
The output of F/F8 is differentiated, and only the differentiation time T is OR1
9- is input. The output of OR19 is used as a JAM circuit output to control each circuit. The JAM circuit output is OR1-, OR in Figure 47.
2-, OR5-, the output of OR1 resets the electromagnetic clutch 85c control F/F1,
The output of OR2 resets the card drive F/F2, and the output of OR5 resets the crimp plate opening/closing control F/F4. By resetting F/F1, F/F2, and F/F4, the electromagnetic clutch 85c, drive motor 103, solenoid 90, solenoid 96, and solenoid 141, which were energized and driven by each driver, are de-energized. The system waits for manual operation of the reset switch (see FIG. 40), which will be described later. After operating the copy start switch, the tip of the aperture card reaches the first detection element 97 within a predetermined time.
If the aperture card 2 does not pass through the card hopper 82, the aperture card 2 is sent out from the card hopper 82 by the operation signal of the copy start switch and the card feed signal that passes through a condition determination circuit (not shown).
If the aperture card 2 becomes stagnant due to the burr 1, the aperture card 2 may be damaged. To prevent this, the card supply signal will
Set the JAM detection timer shown in Fig. 47, input its output to AND1-, and connect the aperture card 2.
The tip of the signal is ANDed by inverting the signal passed through the first detection element 91. In other words, it is output when the aperture card 2 does not pass before the timer is set up. Further, when the electromagnetic clutch 85c and the drive motor 103 are not energized, or when the electromagnetic clutch 85c and the drive motor 103 are out of order, the drive is not transmitted to the aperture card 2. AND1 is also output at this time. The output signal is OR16- in Figure 52.
Similarly to the operation of the two-sheet detection signal micro SW 87, the electromagnetic clutch 85c and drive motor 10
The power supply to the three solenoids 90, 96, and 141 is cut off, and the state waits for manual operation of the reset switch, which will be described later. The tip of the aperture card is the first detection element 97
If the tip of the aperture card does not pass the second detection element 104 within a predetermined time after passing through the card hopper 82
The leading edge of the aperture card 2 is sent out in the direction of the feeding path 101, passes through the first detection element 91, and is brought into contact with the feeding roller 88 and the first pinch roller 89 by the urging force of the solenoid 90. Although the card is fed in the right direction, if the solenoid 90 is not driven for some reason, the aperture card loses drive and stops immediately after passing the separation knife 81 and separation roller 85. Unable to position Aperture Your Card 2. In other words, it is not possible to move on to the next operation. In addition, if the card rear end stopper 92 is locked or the crimp plate does not open and close normally, the aperture card will be stopped at the abnormal area and driven. It may damage the card. In order to prevent this, a JAM detection timer is set based on the passing signal when the tip of the aperture card passes through the first detection element 91, and its output is input to AND2-, so that the tip of the aperture card 2 is detected within a predetermined time. It is checked whether the second detection element 104 passes. The output is inputted to OR16- in FIG. 52, and the electromagnetic clutch 85c, drive motor 103, and solenoids 90, 96, and 141 are de-energized as before, waiting for manual operation of the reset switch, which will be described later. The tip of the aperture card is the second sensing element 1.
If the tip of the aperture card does not pass the third detection element 97 within a predetermined time after passing through 04; The aperture card is fed rightward by the first pinch roller 89, and after the tip of the aperture card passes the second detection element 104, the feeding roller 94 and the solenoid 96
However, if the solenoid 96 is not driven for some reason, the aperture-your-card is fed further to the right by the second pinch roller 95 that is brought into contact by the biasing force of the first pinch roller 89 and the feeding roller 88. The moment you leave it, the drive is cut off and the aperture card stops. In other words, you cannot move on to the next action. In addition, if there is a scratch on the feed path 114 and the tip of the aperture card 2 hits the scratch, the aperture card 2 may be damaged because the drive is applied while it is stopped at the abnormal part. there's a possibility that. In order to prevent this, a JAM detection timer is set based on the passing signal when the tip of the aperture card passes through the second detection element 104, and its output is input to AND3-.
It is checked whether the tip of the sensor has passed the third sensing element 97 within a predetermined time. The output is input to OR16- in FIG. 52, and the drive motor 103 solenoid 9
0, 96 and solenoid 141 (see FIG. 16) are de-energized, and the state waits for manual operation of a reset switch, which will be described later. If the next aperture card 2a is fed for some reason after the tip of the aperture card 2 passes the third detection element, the next aperture card 2a is fed as described above and the first detection element Aperture your card 2 on element 91
When the tip of a passes, check with AND4,
The output is input to OR16- in Fig. 52,
Reset each control F/F 1, 2, and 4. The drive F/F2 is reset by the third detection element 97, but it is a double safety device in case the OR2- input is not output to OR2 for some reason.

is input, and jam detection F/F8 is set. The JAM signal is input to a condition determining circuit (not shown). When the reset switch (see FIG. 40) is pressed in this state, the reset F/F9 is set and its output is input to AND10-. The output of OR16 remains in the "H" state until the jam detection signal is released. Input the inverted signal of that signal to AND10-, input the initial state determination signal of the enlarger to AND10-,
When the enlarger returns to the initial state and the jam detection signal is released, AND16 is outputted and inputted to OR17-, and the output of OR17 resets the jam detection F/F8. As a result, the condition discrimination circuit
The operation signal of the copy start switch (FIG. 40) becomes valid, and the copying operation resumes as described later (see FIG. 45e). At this time, the output of reset F/F9 and jam detection F/F8 (Fig. 53) receive the reset signal.
Take AND11, set the forced ejection timer,

A stop output is output at 0-, which is input to AND6a- of the card automatic ejection signal (Fig. 49).
There is no next aperture card at the position of the first detection element 91, and the second detection element 104 and the third detection element 9
It is detected that the aperture card 2 is present between the card 7 and the card 7, and an automatic ejection signal is output. (Position where ejection is possible) The automatic ejection signal is input to the set terminal of the scan control F/F 5 shown in FIG. 51, and the driver 7 energizes and drives the electromagnetic clutch 313 (see FIG. 18). The carriage 111 is connected to a main drive motor 305 and an electromagnetic clutch 313 or 317 in FIG.

Output. Invert this signal and use AND7a.
AND (output of AND7a) outputs an automatic discharge signal. The automatic discharge signal is input to OR4- in Fig. 47, and the output of OR4 is used to control F/F4 for opening/closing the crimp plate.
is set, the solenoid 141 is energized, and the glass pressure bonding plates 93 and 93a are opened. The automatic discharge signal is input to OR11- in FIG. 51, and the output of OR11 sets F/F6 for controlling the solenoid 153, so that the solenoid 153 is energized and driven. The automatic eject signal is input to OR13- in Fig. 51, and the output of OR13 sets the eject motor control F/F7, and the eject motor

If for some reason the aperture card 2 stops feeding at a position where only the second detection element 104 is operating, press the reset switch (Fig. 40) and the reset output shown in Fig. 52 will be activated as described above. The JAM circuit output is output, and the reset output is the AND of Figure 48.
6-, and it is determined whether or not automatic ejection is possible. If the two-card detection micro switch 87 is not turned on and the tip of the aperture card has not reached the third detection element 97, AND6 is output. The output automatic discharge signal is input to OR6-, and the output of OR6 sends a set signal to F/F1 for controlling electromagnetic clutch 85c, F/F2 for drive control, and F/F4 for controlling the opening and closing of the crimping plate. However, F/F1 is not set because a reset signal is output due to the condition of AND4. In FIG. 14, the stopped aperture card 2 is moved by a first pinch roller 89 that is brought into contact with the roller 88 and the solenoid 90, and a second pinch roller 95 that is brought into contact with the roller 94 and the solenoid 96.
is fed to the right by Aperture Your Card 2
The F/F2 is reset by the passing signal when the tip of the solenoid 90 passes the third detection element 97, and the solenoid 90,
96, the power supply to the drive motor 103 is cut off, and then positioning is performed. (Refer to the above-mentioned positioning operation) After positioning, the operation moves to automatic ejection or copy operation restart depending on the condition of the above-mentioned stop key operation (stop output in Fig. 53). When the aperture-your-card 2 stops at a position where both the first detection element 91 and the second detection element 104 are activated, automatic ejection or copying operation resumes in the same manner as when the aperture card 2 stops with only the second detection element 104 activated. I do. When feeding stops at a position where only the aperture-your-card 2 or the first detection element 11 is operating.The difference from the automatic ejection described above is that the aperture-your-card 2 only operates the first detection element 91. When the card is stopped at the position where the rear end is held by the separation roller 85 and the separation knife 81, the card can be returned to the card hopper 82 using the manual knob 85b, and the reset switch 56
4 (Figure 40), AND1 in Figure 52
When the condition 0 is satisfied, the jam detection F/F 8 is reset by the OR 17, and the reset F/F 8 is reset by the reset signal via the OR 18-, and the next copying operation is ready. In the case of automatic ejection, the electromagnetic clutch 85c operates until the leading end of the aperture card 2 passes the second detection element 104 to assist in feeding. Other operations are the same as those described above. Two aperture cards 2 are sent by the roller 86,
Even if the card 102 is fed in duplicate, only the succeeding aperture card 2a can be returned to the card hopper 82 by rotating the manual knob 85b, and furthermore, after the preceding aperture card is automatically ejected, the copy card 2a can be returned to the card hopper 82 by rotating the manual knob 85b. We can move on to restart work. Furthermore, this device has the following functions.
In FIG. 14, mark detection elements 75, 76, 77 and 78 are installed in the feed path 101 of the aperture card 2, facing a reflector 79, and are applied to the aperture card 2 as shown in FIG. Marks 72, 73, 74 that record information on the micro-image
And the mark 71 for taking these timings is read from the aperture card fed. The relationship between the information marks 72, 73, 74 and the mark detection elements 75, 76, 77 will be explained later. There is a problem if an aperture card whose left and right sides are reversed or whose top and bottom are reversed is mixed in among the large number of aperture cards set in the card hopper 82. Therefore, the mark detection element 78 that detects the timing mark 71 of the aperture card 2 controls the F/F 10 for detecting normal card feeding. AND12 shown in FIG. 54 is an example. The conditions include the contents of the information marks 72, 73, and 74 (which become "H" when the conditions such as magnification and enlarged copy size are met), which will be described later, and it is assumed that these conditions are met. The aperture card 2 is fed from the hopper 82 and the leading edge passes the mark detection 78.F/F10 is set by the passing signal (condition is taken with AND12). However, if Aperture Your Card 2 is upside down left/right or upside down, F/F10
is not set. The F/F11 is an F/F for controlling a light source lamp, and is outputted in synchronization with a copy start operation signal by a condition determining circuit (not shown). After passing through the mark detection element 78, the aperture card 2 is further fed to the right in FIG. F/F11 (AND
output and OR23 output). In other words, if the aperture card 2 is upside down horizontally or upside down, it will not be exposed. Furthermore, the aperture card 2 is fed in the right direction, and the passing signal from the tip of the card passing through the third detection element 97 is inputted to OR16- via AND14, and the jam detection F/F8 (Fig. 52) is inputted to OR16-. Set. Aperture card reset switch 56
With the 4ON operation, the fluid is automatically discharged as described above through the forced discharge circuit shown in FIG. 53. A mark release switch also allows you to enlarge and copy cards without marks. This device clears the carriage 1 by the initial clear signal generated by turning on the main switch.
11 feeding path 101 has means for detecting the presence or absence of a remaining aperture card. In Fig. 52, when the power is turned on by the main switch,
The POWER, ON timer outputs an initial clear signal (hereinafter referred to as I.C.) for a predetermined period of time, setting each control F/F, register, etc. to the initial state. When the I/C signal falls, the OR16 determines whether it is a jam signal from the copying machine or an operation signal from the two-sheet detection micro switch 87. If the signal is output, set the jam detection F/F8. do. In addition to the above signals, the detection signals of the first to fourth detection elements are checked. If there is a signal, the output of AND8 becomes "H", and if it is determined by the check signal obtained by differentiating the I/C signal falling signal, it is output from AND9 and F/F8 is set. In other words, the aperture card remains in the carriage 111 and the feeding path 101. This detection is performed because the distance between the first detection element 91 and the second detection element 104 is shorter than the feeding direction of the aperture card 2, and therefore, the position of the aperture card 2 on the carriage 111 and the feeding path 101 is determined. Even if there is a problem, it can always be detected by the first to third detection elements.
Furthermore, by making it possible to maintain the state of F/F10 even when the power is turned off, it is possible to detect whether a left-right card is set upside down or upside down, and automatically eject the card. In addition, the copy restart operation can be interrupted by the forced ejection switch. Here, I would like to briefly explain the display when the aperture card is jammed. If there is an abnormality in the enlarge device, the jam detection F/
F8 is set, and its output passes through the driver 12 and illuminates the table 522d shown in FIG. Further, the flash circuit causes the display 525a to blink, and if the alarm key is set, a buzzer sounds. To make an intermittent sound, connect it to the flash cycle to make an intermittent sound. The reset switch display shown in FIG. 40 is lit in the same way. Depending on the content of the jam, the display 562 lights up or blinks as described below (see FIG. 55). First, when the two-sheet detection switch 87 is in the ON state, When the switch 87 is turned ON, its output is sent to the display 5 shown in FIG. 40 through the driver 14.
62a is lit, and its output and F/F8
The condition is determined using (JAM) (AND16) and the output is used to flash the display 523d using the flash circuit. When only the first sensing element 91 is in the sensing state,
It is output by AND17 and only the display 563d blinks. When the first detection element 91 and the second detection element 104 are in the detection state, the display 563a blinks with AND17, and the display 536b blinks with AND18. Second
In the case of only the detection element 104, only the display 536b blinks in AND18, and the aperture card is fed by automatic card ejection, and the blinking is turned off in response to a passing signal that the leading end passes the third detection element. When the aperture card is in the automatic ejection position, the display 536c blinks due to AND19. If the aperture card is upside down or left and right, the driver 11 lights up the display 562d.
