Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying apparatus for obtaining copies of originals such as documents, films, etc.

As a manuscript for copying, for example, microfilm has a first
As shown in Figures Λ, B, and C, there are various types such as a roll film F1, a fish film F2, and an aperture card F3.

Roll film F1 has a large number of image frames a on a long film.
1 to a4, bl... are arranged in a line, and a search or positioning mark M is provided on the side of each frame. Fish film F2 is a rectangular film with a large number of image frames. a1 to a4, bl, . A reader printer is used to obtain copies from such microfilm. The reader printer projects the image of the desired frame on the microfilm onto the screen, observes the image, positions the part of the frame that requires copying at a predetermined position on the screen, and then presses the copy button to print the image to the printer. is activated to obtain a copy. Normally, a plurality of image frames with related information contents are arranged consecutively on a microfilm. For example, in the roll film F1 and fish film F2 shown in FIG. 1, four consecutive frames al, a2, a3, The image a4 constitutes one unit of related information, and in the aperture card F3, a plurality of aperture cards constitute one unit of related information.

When copying multiple related image frames in succession, the operator must feed the film or insert the aperture card while the printer finishes one copying operation and moves on to the next copying operation. It is necessary to replace it, project the next image on the screen, observe it, position it in a predetermined position, and then operate the copy button. Therefore, when one unit of information is composed of many image frames or aperture cards, the operator must perform image exchange/positioning operations and copy button operations many times, making the operations complicated and inconvenient. It was hot. In addition, there is a known device in which when the number of continuous copies is set using a dial and the copy button is pressed, the copying operation is started and the set number of copies are automatically made continuously, but it is not necessary to replace the original. The user has to operate the copy button each time, which is troublesome and takes a long time to complete the copying process.Furthermore, the operator cannot leave the apparatus while copying.

The object of the present invention is to eliminate the above-mentioned disadvantages and provide a copying apparatus that can automatically obtain a predetermined number of copies for each document. This figure shows a reader printer that uses the applied rolled film, and the entire device is composed of a printer device 1, an operating device 2, and an observation device 3. The printer device 1 includes an electrophotographic photoreceptor, an exposure means, It is composed of a charging means, a developing means, a transfer means, a copying material feeding means, a drying and fixing means, etc. o Such a printer device is known from, for example, Japanese Patent Application Laid-Open No. 8247/1999, so the explanation will be omitted. The microfilm F is stretched between two reels 4 and 5, and feed rollers 6 and 7
0 transferred from the left reel 4 to the right reel 5 by the rotation of
The microfilm F is illuminated by a lamp in an exposure area formed on the upper part of the printer device 1. The image of the image is selectively projected by a projection lens 8 onto either the photoreceptor of the printer device 1 or the screen 9 of the observation device 3.

This selection is performed by rotating a mirror (not shown) placed on the optical axis of the projection lens 8.The screen 9 is a transmission type screen, and has a copy frame that serves as an index for positioning the film image at a predetermined position. The observation device 3 provided with the observation device 10 is composed of optical means such as a mirror.
The front panel 11 of the 0 operating device 2, which is well known in Japanese Patent Laid-open No. 174 and Japanese Patent Application Laid-Open No. 50-80124, and will not be described here, includes:
a power switch 12 that supplies power to a printer device, etc.;
Copy density adjustment dial 13, copy cycle adjustment dial 14, repeat/manual mode selection switch 15
, copy skip button 16, repeat stop button 17, copy button 18, and copy number setting dial 1
9 are arranged. FIG. 3 shows a printer control unit for controlling the operation of the printer device 1.
In Figure 3, 20, 21 are OR gates, 22, 23
, 24, 25 are AND gates, 26 is an inverter, 27
As shown in FIG. 4, the printer control circuit 27 includes a printer drive control circuit 80 that operates the various processing means of the printer device 1 in a predetermined time order according to a predetermined sequence, and a copy control circuit 27. The printer drive circuit 81 is composed of a counter 81 that counts the number of operations, and a comparison circuit 82 that compares the counted value of the counter 81 and the set value of the copy number setting dial 19. A high-level end signal is output from the output terminal a1 every time one copy material is discharged.

This end signal is output when exposure scanning of a frame in the exposure section is completed. For example, in the case of a scanning method in which the document table that holds the microfilm is moved to scan the document, when the document table is moved and the image has been scanned and the document table returns to its home position, or when the document table is fixed and the microfilm is fixed, the mirror In the case of a scanning method in which the document is scanned by moving the mirror, the scanning of the image is completed by moving the mirror, and when the mirror returns to its home position, the position of the movable document table or the movable mirror is detected by a micro switch, etc. The configuration is such that a termination signal is obtained from this microswitch. Note that this end signal may be obtained in conjunction with the operation of the developing means, transfer means, copying material feeding means, etc. The counter 81 sequentially adds and counts this end signal. counter
When the counted value of 81 matches the number of copies set by the number of copies setting dial 19, a high level match signal is output from the output terminal a2, and this match signal makes the printer drive control circuit 80 inactive and the counter 81 is reset. Therefore, when a high-level copy start signal is sent from the OR gate 20, the printer drive control circuit 80 continuously operates the printer device until the set number of copies is obtained. In FIG. 3, numeral 40 indicates a feed control circuit that controls the feed of the film F. The feed control circuit 40 operates to feed the film when it receives a high level signal from the OR gate 21. , as shown in FIG. 5, a light source 41 that illuminates the mark M on the film F, and a light receiving element 42 that detects the mark M.
, a mark detection circuit 43, and a motor 44 that rotates the feed rollers 6 and 7.

When the feeding control circuit 40 receives a high-level signal from the OR gate 21, it drives the motor 44 to rotate the feeding rollers 6 and 7 to feed the microfilm F, and sends the microfilm F to the light receiving element 42.
When detects the mark of the next frame, the motor 44 is stopped and a high level film stop signal is output from the output terminal b.

As a result, the image frames of the film are exchanged dynamically in the exposure section. In FIG. 3, reference numeral 28 indicates a timer circuit, which is activated when it receives a film stop signal from the feed control circuit 40 and starts measuring time, and when a set time has elapsed, a high level copy is sent from the output terminal c. Generates a start signal, completes time measurement, and becomes inactive. Figure 6 shows a specific example of a timer circuit, in which 50 is a flip-flop circuit, 51 is a variable resistor, and the copy cycle adjustment dial 14 By operating this dial, the resistance value of the variable resistor 51 changes and the setting time is adjusted. 052 and 53 are diodes, 54
55 is a resistor, 55 is a capacitor, and 56 and 57 are inverters.

FIG. 7 shows the waveforms at each point A1 to A4 of the timer circuit. Waveform lines A1, A2, A3, and A4 in FIG. The set time of the circuit, t2, indicates the pulse width of the copy start signal. In addition, as a timer, a combination of cams and microswitches with different set times may be used to adjust the set time, Various other known devices can be applied. In FIG. 3, 29 is a delay circuit;
0 indicates a skip circuit, and the skip circuit 30 is composed of a flip-flop circuit, and its set input terminal d is connected to the copy skip button 16, and its reset input terminal e is connected to the copy skip button 16 through a delay circuit 29. It is connected to the output terminal of the AND gate 24, and the set output terminal f is connected to the input terminal of the inverter 26.

Next, the operation of the reader printer described above will be explained with reference to the time chart shown in Fig. 8. First, turn on the power switch 12, and switch the repeat/manual mode switch 15 to repeat mode in order to obtain copies of a large number of images. .

As a result, a high level signal is input to one of the human input terminals g of the AND gate 22. On the other hand, the copy skip button 16 and the repeat stop button 17 are kept off. At this time, a low level signal is output from the output terminal f of the skip circuit 30 (FIG. 8F), and a high level signal is output from the output terminal of the repeat stop button 17 (FIG. 8B). 〇Next, the first frame of a desired unit of information is placed in the exposure section using an automatic search device or the like. 〇The operator positions the frame correctly in the copy frame 10 while observing the image of this frame on the screen. .

Next, set the required number of copies of the positioned image using the setting dial 19, and then press the copy button 18. When the copy button 18 is turned on, the image on the screen disappears.
The device shifts from the observation state to the printer state. When the copy button 18 is turned on, a high-level copy start signal (
8A) is output, and this signal activates the printer drive control circuit 80 via the rear gate 20, whereby the image of the frame placed in the exposure section is exposed to the photoreceptor and the first copy is made. The operation is performed (FIG. 8C).

The printer drive control circuit 80 repeatedly operates the printer device until a set number of copies are obtained, and stops operating when a match signal is sent from the comparison circuit 82. After a set number of copying operations have been performed, a high-level match signal (D in Figure 8) is output from the comparator circuit 82. When this match signal is output, the image is projected onto the screen again and becomes observable. At the same time, this coincidence signal activates the feed control circuit 40 via the OR gate 21 to drive the motor 44. As a result, the film F is fed, and when the mark detector detects the mark of the next frame, the film stops. , a high level film stop signal from the feed control circuit 40 (Fig. 8E)
) appears 0 This film stop signal causes timer circuit 2.
8 is activated, the o timer circuit 28 generates a copy start signal (FIG. 8G) after a set time t1.

After replacing the image frame in the exposure section, the operator performs work such as positioning the second frame placed in the exposure section until the copy start signal is output, that is, within the set time t1.

When the set time is reached, the repeat stop switch 17 and the skip button 16 are turned off, and the mode changeover switch 1 is turned off.
5 is switched to the repeat mode, the copy start signal output from the timer circuit 28 causes the AND gate 25,
23 and 22 are opened, the printer drive control circuit 80 is activated again via the OR gate 20, and the copying operation of the second frame is performed.0 When a predetermined number of copies of the second frame are obtained in the same manner as described above, the printer drive control circuit 80 is activated again via the OR gate 20. The third frame is automatically placed in the exposure area in place of the frame.Observing the third image,
If it is not necessary to copy the th frame, the operator presses the copy skip button 16 before the timer circuit operates for the set time t1.0 By turning on the skip button 16, the output terminal f of the skip circuit 30 goes to a high level. (Figure 8F). After the third frame is placed in the exposure area, when the skip button 16 is turned on, a copy start signal is generated from the timer circuit 28, but since the AND gate 23 is closed due to the skip button 16 being turned on, the printer drive control circuit 80 does not operate, and continuous copying is temporarily interrupted. On the other hand, when the skip button is turned on, the skip circuit 3
Since the output terminal f of 0 is at high level, the copy start signal opens the AND gate 24 and the OR gate 21
The feed control circuit 40 is operated via the motor 44, the film is transferred, the frame in the exposure section is exchanged, and the fourth frame is placed in the exposure section.After the 0 frame exchange is completed, a film stop signal is sent. Then, by turning on the skip button 16, the feeding control circuit is activated without performing the next copying operation, and the mode is switched to a mode in which the document is exchanged.

When the AND gate 24 is opened, the skip circuit 30 is reset after a predetermined period of time via the delay circuit 29, and the output terminal f becomes low level (FIG. 7F), thereby causing the signal output from the timer circuit to perform the copying operation. Automatically switches to the original mode 〇Therefore, after the operator replaces the third piece with the fourth piece without copying it, the operator needs to copy the next piece, that is, the fourth piece, within the set time t1. 〇If you do not want to copy several frames after the fourth frame, you can press the skip button 16 repeatedly at appropriate intervals for the number of frames that do not need to be copied.〇After resetting the skip circuit 30, the timer circuit 28 When the copy start signal is generated again, the AND gates 25, 23, and 22 are opened, the printer drive control circuit 80 is activated via the OR gate 20, and the copying operation for the fourth frame is performed.

After that, the operator confirms the image position and image content, and can automatically copy each image at preset time intervals without pressing the copy button. (referred to as "repeat copy").
To stop repeat copying, press the repeat stop switch 17 to close the AND gate 25. Therefore, the copy start signal from the timer circuit 28 is not sent to the printer drive control circuit, and the next copying operation and image exchange are performed. is not performed and the repeat copy ends 〇Please note that the repeat/
Repeat copying can be similarly stopped by switching the manual mode changeover switch 15 to manual mode.

When the mode selector switch 15 is switched to manual mode, each time the operator presses the copy button 18, a copying operation is performed and the printer can be used in the same way as a normal printer. According to experiments, it is possible to examine the content of the image and copy the image. The time required for positioning etc. varies depending on the ability and experience of the operator, the content of the image, etc., but is generally about 2 seconds.

Therefore, the set time t1 can be changed to an appropriate time by operating the copy cycle adjustment dial 14 according to the skill level of the operator. If the operator is an experienced operator, the copying process can be done in a short time by shortening the setting time and shortening the copy cycle; if the operator is inexperienced, the setting time can be lengthened. According to the present invention, when a plurality of originals are automatically and continuously copied, if there is an original that does not need to be copied, the repeat copying is interrupted by the selection means, and the next original is automatically copied without copying this original. You can replace the original with the original and perform automatic continuous copying again from the next original.
The copying operation is simplified and the copying work can be completed in a short time.In addition, the operator does not need to press the copy button every time the original is replaced or every time the copying operation is restarted after interrupting repeat copying. The automatic copying cycle can be set arbitrarily, taking into account the time required to examine the contents of the original, correct the bending of the original, or adjust the position of the original, which eliminates the hassle of operation. It can reduce the burden on the operator when making copies of documents, etc. It is also possible to proceed with the copying work as the set time of the copying cycle has elapsed, and the copying operation can be started while the content of the original is being considered or the positioning is being determined. It is possible to prevent the accident of making a mistake by copying, and even an operator who is not familiar with the machine can perform copying work with peace of mind.

Note that the present invention is not limited to microfilm reader printers, but can also be applied to copying machines that use manuscripts such as documents and drawings, and the copying method is not limited to electronic photography, but can also be applied to methods such as silver halide photography and heat development photography. You can also do it 〇
