Description

[Detailed description of the invention]

The present invention relates to a recording device having a folding device. For example, when a sheet-like recording material with image information recorded and discharged from a recording device such as a copying machine is large in size, it is preferable to manage the recorded sheet-like recording material by folding it in two. Conventionally, a sheet of recording material ejected from a recording device was folded in two by a person and then collated again in the order of copying. In recent years, in order to alleviate such troubles, a recording apparatus which has a folding means and which folds and discharges recorded recording material has been proposed, for example, in Japanese Patent Publication No. 49-44416. In order to select the folding operation in such a device, the large-sized recording material is selected by key input, and then the folding mode or non-folding mode is selected by key input. The selection, mode selection, etc. were troublesome and were not easy to use. The present invention has been made in view of the above points, and an object thereof is to provide a recording device that reduces the troublesomeness of the operator and has improved usability. That is, the present invention includes first detection means 123, 124 for detecting the size of a document, a plurality of storage means 4 ₁ , 4 ₂ for storing recording materials, and detecting the size of the recording materials stored in the plurality of storage means. Second detection means 12
6. In accordance with the detection outputs of the first detection means 123, 124 and the second detection means 126, a storage means storing a recording material of a size corresponding to the document size is placed among the plurality of storage means 4 ₁ , 4 ₂ A first selection means 140, 142, 153 to 158 selected from among the above, and recording of copying an original image to a recording material fed from a storage means selected by the first selection means 140, 142, 153 to 158. Means 17, 18, 2
6 to 29, 32, 34, the recording means 17, 1
Processing means 106 to 110, 118 that can operate in a first mode in which the recorded recording material conveyed from 8, 26 to 29, 32, and 34 is folded and discharged, and a second mode in which the recording material is discharged without folding. , the first detection means 123, 1 for each series of recording operations for the set number of sheets.
The present invention provides a recording apparatus characterized in that it has second selection means 141, 147 to 149 for selecting either the first mode or the second mode according to the document size signal output from . According to the present invention, since the document size is detected and both the recording material selection and the folding selection are automatically performed according to the detected size, it is possible to significantly reduce the annoyance of the operator and improve usability. becomes possible. First, an example of a copying machine to which the present invention is applied will be explained. This copying machine is a powder development transfer type copying machine.
The originals to be copied include sheet-like documents, thick originals such as books, etc., and the structure is such that all kinds of things can be easily copied. In FIG. 1, 1 is a machine box, 2 is a document table on which a document is placed, and a document auto feeder 3 covers the document table. 4 ₁ , 4 ₂ are transfer sheets of different sizes 5 ₁ ,
5 is a cassette that stores ₂ , and 6 is a tray on which transfer paper that has been transferred and is discharged from the machine is placed. 7 is the main switch, 8 is the warning display section, 10
1 is a paper size display section, 11 is a copy density adjustment dial, 12 is a continuous copy number selection key, 13 is a continuous copy button that is linked to it, and 14 is a non-linked 1
The copy button 15 indicates a stop button for canceling continuous copying. A hopper is located at the front right where the door is opened to store replenishment developer and send it out as needed. The operation of this copying machine will be explained with reference to FIG. The document glass 16 is moved by the document auto feeder 3.
Place the original to be copied on top of the glass with the tip 1
6 Place it according to ₁ . Next, when the copy button 13 or 14 is pressed, the photosensitive drum 17 starts rotating clockwise in the figure. When the photosensitive drum 17 reaches a predetermined position and a signal to start exposure is issued, the illumination lamp 18 and first mirror 19, which are the movable parts of the optical system,
starts moving rightward in the figure at the same speed as the circumferential speed of the photosensitive drum 17, and the second mirror 20 also starts moving rightward in the figure at half the speed. The image of the document illuminated from below by the illumination lamp 18 is transferred onto the photosensitive drum 17 at the exposure section 24 by an optical system consisting of a first mirror 19, a second mirror 20, a lens 21, a third mirror 22, and a fourth mirror 23. Form an image. When the exposure is completed, the movable part of the optical system detects its position, stops moving to the right, and immediately returns to the opposite direction, that is, to the left. This return speed is made faster than the forward speed to increase copying efficiency. and,
When it returns to the initial position, the drive to the optical system movable part is cut off and it stops. When copying a large number of copies continuously from the same document, it is sufficient to specify an arbitrary number of copies using the continuous copy number selection key 12 and start the copying using the continuous copy button 13. Furthermore, by starting with the single copy button 14, only one copy can be made regardless of the number of copies specified by the copy number selection key 12. The photosensitive drum 17 has a three-layer structure in which a photosensitive layer on a conductive substrate is covered with a transparent insulating layer.
Rotate clockwise as shown. The drum 17 is first charged by a positive charger 26 that is supplied with a high voltage current from a high voltage power source. Subsequently, when it reaches the exposure section 24, the image of the document described above is subjected to slit exposure and at the same time is AC charged (discharged) by an AC charger 27 supplied with AC high voltage current from a high voltage power supply. Then, an electrostatic latent image is formed on the surface of the photosensitive drum 17 by the next full-face exposure using the full-face exposure lamp 28 and enters the developing device 29 . In the developing device 29, the carrier on the sleeve 31 rotating around the magnet 30 comes into contact with a magnetic brush made of toner, so that the electrostatic latent image on the photosensitive drum 17 is developed and visualized. Next, the transfer paper 5 sent from the paper feed section is brought into close contact with the photosensitive drum 17, and the transfer charger 32 charges the photosensitive drum 17 with a high voltage current from a high voltage power supply, so that the developed image on the photosensitive drum 17 is transferred onto the transfer paper 5. transcribed. After the transfer, the transfer paper 5 is separated from the photosensitive drum 17 by being restrained at one end by a separation belt and guided to the fixing device 34. The edge portion 35 ₁ of the cleaning blade 35 is pressed against the photosensitive drum.
The remaining toner is wiped away and the next cycle is repeated. The toner wiped by the cleaning blade 35 rises onto the cleaning blade 35 and is removed by the screw 36 from the photosensitive drum 17 on the front side in the figure.
The developing unit 2
9 and used again for development. Transfer paper 5 ₁
is stored in the cassette ₄₁ , and the transfer paper ₅₂ is stored in the cassette _{42 .}
It is removably attached to 38 ₂ . Various cassettes are available for different sizes of transfer paper, and can be easily replaced as needed. The selection of paper feed from the paper feed section 38 ₁ or 38 ₂ is performed by an automatic cassette selection device, which will be described later. When the photosensitive drum 17 reaches a predetermined position and issues a paper feed signal, the constantly rotating paper feed roller 39 ₁ or 39 ₂ is pressed onto the transfer paper 5 ₁ or 5 ₂ by an electromagnetic drive device (not shown). Transfer paper 5 ₁ or 5 ₂
is sent out to the right in the figure. Next, the first register rollers 40 ₁ , 41 ₁ or 40 ₂ , 41 ₂ prevent skewing and send the paper in the correct direction. Subsequently, the second register rollers 42 and 43 synchronize with the image on the photosensitive drum 17 using signals from the movable part of the optical system, and then the transfer paper 5 is brought into close contact with the photosensitive drum 17 as described above, and the image is transferred thereto. . After the transfer is completed, the transfer paper is peeled off from the photosensitive drum 17 by the separation belt.
Next, it enters the fixing device 34. In the fixing device 34, a transfer paper 5 having an unfixed image on its surface is passed between a peelable elastic fixing roller 46 heated by a heating roller 45 having a heater 44 inside and a facing roller 48 also having a heater 47 inside. As the toner passes through and is heated, the toner is thermally fused and the image is fixed on the transfer paper 5. After the transfer paper 5 leaves the fixing device 34, the charge remaining on the surface is finally removed by the static eliminator 49, and then the transfer paper 5 is transferred to the discharge rollers 50, 51.
The paper is discharged onto the guide plate 103 of the folding device. The photosensitive drum 17 of this copying machine is capable of copying up to the width of A3, and its outer circumference is somewhat longer than the length of A3. On the other hand, after the forward movement (exposure stroke) of the optical system movable part, the backward movement requires approximately the same time as the forward movement. Therefore, in the case of A3 copying, one sheet is printed for every two revolutions of the photosensitive drum, and in the case of A4 copying,
The transfer paper is fed horizontally (in a direction perpendicular to the longitudinal direction) so that one copy can be made per rotation of the photosensitive drum. The above-mentioned difference in cycle due to paper size is determined by a signal from the cassette 4 ₁ or 4 ₂ selected by an automatic cassette selection device to be described later, and the amount of movement of the movable part of the optical system is controlled. After the copying operation is completed, the trailing edge of the transfer paper 5 is
After passing through the discharge rollers 50 and 51, the photosensitive drum 17 stops. At this time, in order to prevent the cleaning blade 35 from constantly being in pressure contact with the surface of the photosensitive drum 17, which may affect the image, the edge portion ₃₅₁ of the cleaning blade 35 should be placed near the seam of the photosensitive layer, that is, the area where the image does not appear. The photosensitive drum 17 stops at this position. In addition, 52 and 53 are transfer paper 5, cassette 4,
This is a storage space for developer and other consumables. Referring to FIG. 3, the document auto feeder 3 will be described in further detail. A remaining amount switch 121 made of a detection element such as a micro switch is provided in a part of the document table 2 of the ADF, and detects whether or not there is a document 202 on the document table 2. The manuscript must be full size (e.g. A3, B4 size),
Or half size (e.g. A4, B5 size)
However, when placing the original on the original platen 2, the original must be fed horizontally (the width direction of the original matches the direction of transport of the original) for full-size originals. As can be seen, half-size originals are placed so that the originals are fed vertically (the longitudinal direction of the original matches the direction in which the original is transported). The document 202 placed on the document table 2 is moved by the rotor 2.
04, is held between rollers 205, and fed onto the belt 211. The timing of feeding the document is determined by moving the timing roller 206 downward from the state shown in the figure.
The document sent out onto 11 passes through a light emitting element 20.
8 and a light receiving element 209. This switch is arranged at a position where either a full-size or a half-size original always passes, and is shown as an original detection switch 123 in FIG. 8. A switch having a similar structure is arranged in parallel with the switch 123 (shifted in a direction perpendicular to the plane of FIG. However, it is arranged at a position where half-size originals do not pass through, and is shown as an original size detection switch 124 in FIG. Of course, if half-size originals are fed horizontally and full-sized originals are fed vertically, the size of the original can be detected by the time it takes for the original to pass, and the presence of the original can also be detected. It's good. Presser rollers 210 and 212 are placed on the belt 211.
Therefore, the document on the belt 211 is transferred to the right in FIG.
17 and 218, and a guide 219, the document is sent onto a glass table 220 that constitutes the document table of the copying machine. A belt 221 is further wound around the space between the rollers 217 and 223, and the roller 223 moves up and down as shown by arrow F, so that by moving the roller 223 downward, the glass table 220 is fed. The original can be further moved to the left in the figure. Since a stopper 225 is provided at the left end of the glass table 220, the document hits the stopper 225, and at the same time, a motor (not shown) is stopped by the document selection detection output of the document switch 122, and the document transport belt and rollers are stopped. Stops driving. After the predetermined copying of the original is completed, the stopper 225 is retracted from the original transport path, and the roller 22
3 moves downward and rotates, moving the original to the left in the figure, and ejecting the document onto an ejection tray 228 by an ejection roller 226. Next, the folding device will be further explained with reference to FIG. 2 and FIGS. 4 to 6. The transfer paper 5 discharged by the rollers 50 and 51 is guided by a guide plate 103, sent upward by a feed roller 102 and a conveyor belt 104, and guided to a folding part by a presser roller part 105. This folding portion is formed by a pair of rollers 107, 108 and a plunger 1, as shown in FIGS.
19, a roller 106 controlled as shown in FIG. 5 or FIG.
18, etc. To explain the operation of the folding section, when the transfer paper 5 transported upward by the conveyance belt 104 and the presser roller 105 is half size, the "folding signal" shown in FIG. 8 is not derived. Therefore, the guide plate 118 is held at the position shown in FIG. 6 by a spring (not shown), and the roller 106 is moved to the position shown in dotted line in FIG. As shown in FIG. 6, the arm 113 and the stopper 116 are in contact with each other (the position shown in FIG. 6). Therefore, as shown in FIG. 6, the transfer paper 5 coming up from below is guided by the guide plate 118 between the rollers 107 and 108 and is discharged onto the tray 6 as it is. On the other hand, when the transfer paper 5 is full size, a "folding signal" is derived from the circuit shown in FIG. When this folding signal is derived, an electromagnetic drive device (not shown) moves the guide plate 118 to the position shown in FIG.
arm 113 and stopper 117
is held in the position where it stops. Therefore, the transfer paper 5 that has come up from below is held between the rollers 106 and 107 and enters the storage section 109. As shown in FIG. 5, the end portion 11 of the storage portion 109
After the leading edge of the transfer paper 5 hits the roller 10
When the transfer paper 5 is further transported upward by the rollers 6 and 107, a portion 53 of the transfer paper 5 is bent, caught between the rollers 107 and 108, bent, and discharged onto the tray 6. . FIG. 7 shows a timing chart when the apparatus of the present invention makes two copies of each document sent from the ADF to the document table. First, at timing 1, the operator presses the "copy button" 13, but since the original is not set in the ADF,
Indicates that nothing is working. At timing 2,
This indicates that the operator noticed this and set the manuscript. Timing 4 indicates that the operator has pressed the "copy button" again. As a result, the copy conditions are met, so “ADF
This indicates that the document feed motor is activated, one document is taken out, and the document is sent onto the document table. At timing 5, a full-size document is fed, and the document detection switch 1 and document size detection switch 2 are driven. Indicates that the size memory element has been set.
Timing 6 indicates that the document has passed through the switch. Timing 7 indicates that the leading edge of the document sent to the document table has reached the proper position and the "document home position" switch is activated. Therefore, as a result, the "ADF document feed motor" is stopped and the document is stopped on the glass table. Furthermore, based on the result of this stop, the "copy signal" is turned on to drive the main body of the copying apparatus. Simultaneously with this drive, the "folding solenoid 111" is excited in response to the operation of the document size storage element at timing 5. At timing 8, the post-rotation cycle is entered and a "coincidence signal" indicating that the number of copies set by the operator matches the number of copies is generated. Timing 9 indicates that the photosensitive drum in the copying device has reached the home position when the "coincidence signal" is generated, and when these two conditions are met, the copying device is stopped, so " copy signal”
Turn it off. Furthermore, due to this stop, “ADF
The document feed motor is driven to eject the document on the document table and send a new document to the document table.Furthermore, the document size memory element set at timing 5 is cleared, and the size of the subsequent document is stored. Prepared for memory.Timing 1
At 0, it detects that a full-size document has arrived again and remembers that it is full-size. Timing 11 indicates that the original that has been on the original table has been completely discharged from the original table. Furthermore, a "timer" is set by this ejection signal, and this is activated in order to turn off the "ADF document feed motor" at the fall of this timer signal when there is no subsequent document after the timer time elapses. ing. Timing 12 indicates that the original has passed through the original size detection switches 1 and 2. At timing 13, the second document reaches the appropriate position on the document table within the time that this "timer" does not turn off, and the "document home position" is reached.
Indicates that the switch was activated. Furthermore, as in the case of timing 7, the "ADF document feed motor" is turned off, and the "copy signal" that drives the main body of the copying apparatus is turned on. Also, the document size storage element is set again and remembers that the document is full size, so the "folding solenoid 111" continues to be energized. Then, the copy cycle is repeated in the same way. At timing 14, the same operation as at timing 4 is performed. At timing 15, only the original detection switch 1 is set, indicating that a half-size original is being sent, and therefore the original size storage element is not set and the half-size original is memorized. Timing 16 indicates that the document has passed through the switch. At timing 17, the second document is ejected from the document table, and
The third and final document is fed from the ADF's document tray, and the "remaining document amount detection" switch is turned off, indicating that there are no more documents in the document tray. At timing 18, the movement is similar to timings 7 and 13, but at timing 15
Then, in response to remembering that it is half size, the "folding solenoid 111" is turned OFF. At timing 19, after the third and final document is ejected, the document does not appear even after the timer time elapses, so the "ADF document feed motor" is turned on.
Turn it OFF to indicate that all operations have stopped. Now, consider the relationship between the operation of the original size storage element and the time the copy paper takes to reach the folding section. In the circuit according to the present invention, at the rising edge of the copy signal,
That is, the copying machine is designed to respond only when the copying operation begins, and as is clear from the timing chart, the time b' when the last copy sheet for each document reaches the folding section is
Since this is the time when the ADF is sending the next document to the document table, the "folding solenoid 111"
It is unlikely that an inconvenience such as switching occurs. Next, FIG. 8 shows a circuit that embodies the timing shown in FIG. 7 based on the above explanation. The control circuit shown in FIG. 8 includes a copy button switch 120 (its output waveform is the seventh
(Figure A), the remaining amount switch 121 (its output waveform is shown in Figure 7B) that detects whether or not there is a document remaining, and the document switch 122 (its output) that detects whether or not the document is at the home position. The waveform is the 7th
(D), the document detection switch 123 that detects the presence of a document (its output waveform is shown in FIG. 7), the document size detection switch 124 that detects the size of the document (its output waveform is shown in FIG. 7), and the photosensitive drum By installing the drum detection switch 125 (its output waveform is shown in Fig. 7), which detects whether or not the drum is in the position, and the cassette containing the transfer paper into the copying machine, the transfer paper stored in the cassette can be detected. An input signal is obtained by a cassette switch 126 which is driven according to the size. As mentioned above, each switch outputs a high level signal to the contact when the contact is in contact with the "present" or "ON" side contact in the diagram, and outputs a low level signal in other states. This is what we have derived. (However, the cassette switch 126 is the opposite.) Each of the above-mentioned switches is a switch that has already been explained or is a well-known switch, so a detailed explanation thereof will be omitted here. The control circuit shown in FIG. 8 uses the switches as described above as input signals, and receives an "ADF signal" (waveform C in FIG. 7) that commands the drive of the ADF document feed motor, and a "copy signal" that commands the execution of a copy cycle. ” (its waveform is shown in Figure 7), a “solenoid signal” that instructs the driving of the folding solenoid mentioned above, and a “folding signal” (that The waveform is the "upper paper feed signal" or "upper paper feed signal" which commands the drive of the paper feed roller 39 ₁ or the paper feed roller 39 ₂ to feed the transfer paper stored in the upper cassette or the transfer paper stored in the lower cassette. “Lower paper feed signal”
is derived. The ADF signal mentioned above is the RS flip-flop 127
There are two possible timings at which this ADF signal is derived. This is the case represented by timings 4 and 9 in FIG. The case represented by timing 4 is the AND gate 128 in FIG. 8 (however, this AND gate derives a low level output when a low level signal is applied to either input 1 or input 2, The case represented by timing 9 is the case where a low level signal is input to the input 2 of the AND gate 128. In the case represented by timing 4 above, the logic is assembled in the NAND gate 129, so the copy button switch is pressed while the remaining amount switch 121 is in the "present" state and the original switch 122 is in the "absent" state.
When turned on, input 1 of NAND gate 129,
2 and 3 all go high, causing the output to go low, setting flip-flop 127. In the case represented by timing 9 above, the output Q of the RS flip-flop 130 that derives the "copy signal" drives the differentiating circuit 131, and inputs a low level corresponding to the falling edge of the flip-flop 130 to the input 2 of the AND gate 128. The flip-flop 127 is set by inputting the differential pulse. The flip-flop 127 is reset.
There are two possible cases in which the derivation of the ADF signal stops. This is the case represented by timings 7 and 19 in FIG. The case represented by timing 7 is a case where a low level signal is applied to input 1 of the AND gate 132 in FIG.
The case represented by 9 is a case where a low level signal is applied to the input 2 of the AND gate 132. AND gate 132 has a logic structure that outputs a low level signal when a low level signal is input to either input 1 or 2, and resets flip-flop 127. In the case represented by timing 7 above, at the moment when the original switch 122 is switched to "ON", that is, when the output of the inverter 133 changes from high level to low level, the differentiating circuit 134 is driven by the inverter output. , the low level pulse signal generated by the differentiating circuit 134 is applied to input 1 of the AND gate 132 to reset the flip-flop 127. In the case represented by timing 19 above, when the original switch 122 changes from "present" to "absent", a timer 135 is set, and a high level signal is derived from the timer 135 for a predetermined time. . When the timer 135 passes a predetermined time and its output changes from a high level to a low level, the differentiating circuit 136 is driven to apply a low level pulse signal to the input 2 of the AND gate 132 to drive the flip-flop 127. This is for resetting. The above-mentioned "copy signal" is constituted by the set output signal of the RS flip-flop 130, and the case where the flip-flop 130 is set is typified by timing 7 in FIG. The output of the NAND gate 137 is applied to the set terminal of the flip-flop 130, and the output of the original switch 122 is applied to the input 1 of the NAND gate 137. The output of the original switch 122 is applied in this way only when the original switch 122 is on.
This is to allow the flip-flop 130 to set, and to prevent the flip-flop 130 from setting at timing 19 in FIG. 7, for example. At the input 2 of the NAND gate 137, a differentiation circuit 138 differentiates the fall of the output Q of the flip-flop 127, and generates a low-level differential pulse at the moment the output Q changes from a high level to a low level; This differential pulse is inverted by an inverter 139 and then applied. The output of the matching circuit 140 is applied to the input 3 of the NAND gate 137;
The output of an RS flip-flop 141, which is a document size storage element, is applied to input 1 of 40, and the output size signal of the cassette selected by selector 142 is applied to input 2. Therefore, the size of the transfer paper stored in the cassette selected by the original size signal applied to input 1 and the selector 142 (the size referred to here means full size or half size)
Only when they match, a high level signal is derived from the output of the matching circuit 140, and this high level signal is applied to the input 3 of the NAND gate 137. Therefore, the flip-flop 130 has the original switch 122, the original size signal and the transfer paper size match, and the flip-flop 127
It is the one that is set when changes from set to reset. The case at timing 9 in FIG. 7 is representative of the case where the flip-flop 130 is reset and the derivation of the copy signal is stopped. That is, the flip-flop 130 is reset by the output of the NAND gate 143, but the output of the drum detection switch 125 is applied to the input 1, and the contents of the counters 144 and 145 are compared to the input 2. A high level signal is derived when the contents of the two match. The output of the matching circuit 146 is applied. Note that the counter 144 is a counter that stores the number of sheets set by the sheet number setting key 12, and the counter 145 is a counter that counts the number of copies made from the same original. The fold signal is composed of the Q output of the JK flip-flop 147, and this flip-flop 1
The Q output of the flip-flop 141 is applied to the J terminal of the flip-flop 47, and the Q output of the flip-flop 130 is applied to the CP terminal. The flip-flop 141 applies the output of the NAND gate 148 to the set terminal, and the output of the document detection switch 123 is applied to the input 1 of the NAND gate 148, and the output of the document size detection switch 124 is applied to the input 2, so that As mentioned above, switch 12
It is set only when both 3 and 124 outputs are present. In other words, when the flip-flop 141 is deriving the Q output, it indicates that the document size is full size (needs to be folded and ejected), and when the flip-flop 141 is not deriving the Q output (the document detection switch 123 is in the ON state and the switch 124 is in the OFF state), the Q output is not derived and the document size is half size (there is no need to fold and eject the document). As is clear from the above description, the fold signal is derived when the flip-flop 141 derives the full-size signal and the flip-flop 130 derives the copy signal. The output of the differential circuit 131 is applied to the reset input of the flip-flop 141, and the Q output of the flip-flop 141 is applied to the reset input of the flip-flop 141 through an inverter 149.
7, the flip-flop 147 is applied to the K terminal of FIG.
When the copy signal changes from a low level to a high level in a state where it is detected that the document size is half size as shown at 8, the derivation of the Q output (derivation of the solenoid signal) is stopped. The size signal is applied to the matching circuit 140 through the signal line 150, and the derivation of the upper and lower paper feed signals will be explained in more detail below. As mentioned above, the cassette switch 126 is the three switches MS1 to MS3 that are activated when the cassette 41 is inserted into the upper tier, and the three switches MS1 to MS3 that are activated when the cassette 42 is inserted into the lower tier. Three switches MS4 to be driven
Each switch is controlled according to the size of the transfer paper stored in the inserted cassette (cassette size) as shown in the table below.
