Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying apparatus that can automatically and continuously copy a plurality of original documents.

For example, when a microfilm is used as a manuscript for copying, a roll of film F7 is used as the microfilm on which the original image is recorded, as shown in Figure 1 A, B, and C.
3 fish film F23 aperture card F3 etc.

Roll film F is a long film with many frames a1~
A4, bv゜゜゛゜'0 are arranged in parallel, and a search or positioning mark M is provided on the side of each piece. The fish film F2 is a rectangular film in which a large number of pieces a1 to a4, b, . . . are arranged in a grid pattern. The aperture card F3 has a film having one frame or a plurality of frames attached to five apertures of the card. A reader printer is used to copy such an original image on a microfilm onto a copying material. With a reader printer, the image of the desired frame on the microfilm is projected onto the screen, the image is observed, the part of the frame to be copied is positioned at a predetermined position on the screen, and then the copy button is pressed to turn on the printer. I activated it and got a copy. Normally, a plurality of frames with related information contents are arranged consecutively on a microfilm. For example, in the roll film F03 fish film F shown in Fig. 1, four consecutive frames a0, a
Images 2, a3, and a constitute one piece of related information.

In addition, in the aperture card F3, multiple aperture cards constitute one piece of related information, and when a plurality of such related image frames are continuously copied, the printer device makes one copy. After finishing the operation and moving on to the next copying operation, the operator advances the film, replaces the aperture card, projects the next image on the screen 5, and observes it. It is necessary to position it in a predetermined position and then operate the copy button. Therefore, if one piece of information is composed of many image frames or many Apatya cards. The operator has to perform image exchange/positioning operations and operations to press the cobby button many times, which has the disadvantage that operations are complicated and copying operations take time. In order to eliminate such shortcomings. It is known that a rebeat mechanism for automatic copying is provided, and the automatic copying cycle can be set arbitrarily. People who are not familiar with the copying machine they use may not know when to start automatic copying, and may have to replace and position the original. Alternatively, there was a problem in which automatic copying started while reviewing the contents of the manuscript, resulting in copy errors. There was also the inconvenience of not being able to leave the copying machine even if I was able to do other work while I was at work. SUMMARY OF THE INVENTION An object of the present invention is to provide a copying machine that eliminates such inconveniences, eliminates miscopy, and allows copying work to be carried out with peace of mind.

The present invention will be explained below with reference to the drawings. Figure 2 shows a reader printer to which the present invention is applied. It 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, a charging means, a developing means. Transfer means. It consists of copying material feeding means, drying and fixing means, etc. The details of these are given in
It is described in Publication No.-8247, etc. Since this is well known, the explanation will be omitted.

The microfilm F is stretched between two reels 4 and 5, and can be moved from the left reel to the right reel or from the right reel to the left reel by rotating the handles 6 and 7 provided on each reel 4 and 5. Hefilm can be sent. The microfilm F is illuminated by a lamp in an exposure section formed at the top of the printer device 1. The illuminated film image is selectively enlarged and 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 made by rotating a mirror (not shown). Screen 9 consists of a transparent type screen,
A copy frame 10 is provided for positioning the image to be copied on the film. It is configured so that only the image projected within this copy frame 10 is copied. The observation device 3 is composed of optical means such as mirrors. For details, see Japanese Patent Publication No. 51-23174, Japanese Patent Application Publication No. 1983-
Since it is publicly known from Publication No. 80124, etc., the explanation will be omitted. On the front panel 11 of the operating device 2. A power switch 12 for supplying power to a printer device, etc., a Coby density adjustment dial 13, a copy cycle adjustment dial 14, a repeat/manual mode selection switch 15, a Coby skip button 16, a repeat stop button 17, a copy button 18.
, and a display unit 19 that displays the time elapse of the coby cycle.
are arranged respectively.

FIG. 3 shows a printer control circuit for controlling the operation of the printer device 1.0 In FIG. 3, 2
0, 21 are or gates, 22, 23, 24, 25 are and gates. 26 indicates an inverter.

Reference numeral 27 denotes a printer operation circuit that operates various processing means of the printer device 1 in a predetermined time order, and outputs a completion signal from an output terminal a when a predetermined copying operation is performed.

This end signal is output when a predetermined step of the copying operation is completed. For example, in the case of a scanning method in which the document table holding the microfilm is moved to scan the document, the document is scanned when the document table finishes moving and returns to the home position, or by moving a mirror with the microfilm fixed. In the case of the scanning method, when the mirror has finished moving and returned to its home position. The configuration is such that the position of the document table or mirror is detected by a microswitch or the like and a termination signal is obtained from this microswitch. Note that this end signal may be transmitted depending on the operation of the developing process, transfer process, copying material feeding process, or mirror movement process that selectively projects the microfilm image onto either the printer device or the observation device. Preferably, this occurs when the exposure scanning process is completed and the original can be replaced. Reference numeral 40 denotes a transfer control circuit for controlling the film transfer device that feeds the film F, and is activated when receiving an end signal from the printer operating circuit 27 via the OR gate 21.

FIG. 4 shows a film transport device, in which numeral 41 is a light source that illuminates the mark M on the microfilm F arranged in the exposure section, and 42 is a light receiving element that detects the optical signal of the mark M. 43 is a mark detection circuit. Reference numeral 44 indicates a motor that drives the feed rollers 6 and 7. It is controlled by a transfer control circuit 40.

When the transfer control circuit 40 receives the end signal from the printer operation circuit 27, it drives the motor 44 to rotate the feed rollers 6 and 7 to feed the microfilm F, and the mark of the next frame is detected by the light receiving element 42. Then, the motor 44 is stopped and a film stop signal is output from the output terminal b, thereby completing the exchange of image frames on the exposure section. In Figure 3, 28 indicates a timer circuit. When a film stop signal is received from the transfer control circuit 40, it is activated and starts measuring time, and when a set time has elapsed, a high level copy start signal is generated from output terminal c, and when the time measurement is finished, it stops. It becomes activated. 29 is a delay circuit, and 30 is a skip circuit. The skip circuit 30 is composed of a flip-flop circuit, and a copy skip button 16 consisting of a self-recovery switch is connected to its set input terminal d. The output terminal of an AND gate 24 is connected to the reset input terminal e via a delay circuit 29.

In addition, an inverter 26 is connected to the output terminal f of the skip circuit 30.
The input terminal of the AND gate 24 is connected to the input terminal of the AND gate 24, respectively. 99 indicates that the timer circuit 28 is operating. A display device that displays the elapse of the set time of the timer circuit 28.
The display contents of this display circuit are displayed on the display section 19 shown in FIG.

The display device 99 is. As shown in FIGS. 8 and 9, a flip-flop circuit 100, an oscillator 101 . Counting circuit 1
It consists of 02.

The flip-flop circuit 100 is . The set input terminal s
is connected to the output terminal b of the transfer control circuit 40. Its reset input terminal R is connected to the output terminal c of the timer circuit 28. The oscillator 101 is a flip-flop circuit 10
It is connected to the set output terminal of 0 and generates a pulse signal at regular time intervals. This pulse signal is transmitted to the counting circuit 10
It counts as 2.

The counting circuit 102 displays the display unit 1 every time a pulse signal is sent.
9 light emitting diodes LED1, LED2...L
EDn is sequentially turned on and reset by the copy start signal output from the timer circuit 28 to return to the initial state. Therefore, it is possible to know from the number of light-emitting diodes on the display section 19 how the set time has elapsed from when the image frames in the exposure section are replaced until the timer circuit 28 issues a copy start signal for the next copying operation. I can do it. Therefore, the operator must wait until the predetermined display corresponding to the set time is displayed. Consider the position of the new image placed in the exposure area, the content of the image, etc. All you have to do is prepare for the next copy. You can work with peace of mind. Note that the display device is not limited to one that displays the passage of time in an analog manner, but may also display the passage of time numerically.

FIG. 5 shows a specific example of a timer circuit, in which 50 is a flip-flop circuit, 51 is a variable resistor. It is connected to the copy cycle adjustment dial 14. Rotation of the dial 14 changes the resistance value of the variable resistor 51 and adjusts the set time of the timer circuit.

52 and 53 are diodes, 54 is a resistor, 55 is a capacitor, and 56 and 57 are inverters.

The operating time may be set as a timer circuit by a combination of a cam and a microswitch having different set times.

Also. Various known timers can be used. Figure 6 shows the signal waveforms at each point A, ~A4 of the timer circuit, and the waveform lines A1, A2, A,
, A4 represents the signal waveform at each point with the same sign. t1 indicates the setting time of the timer circuit, and t2 indicates the pulse width time of the copy start signal.

The set time t1 of the timer circuit 28 is set to an appropriate time by operating the copy cycle adjustment dial 14, taking into account the time required for the operator to perform observation and positioning of the original. Next, the operation of the reader-printer will be explained with reference to the time chart shown in FIG.

First, turn on the power switch 12, and then turn on the repeat/manual mode switch 1 to obtain multiple copies of images.
5 to rebeat mode. By switching to the repeat mode, a high level signal is input to one input terminal g of the AND gate 22. on the other hand. The copy skip button 16 and rebeat stop button 17 are turned off. At this time, a low level signal is output from the output terminal f of the skip circuit 30 (FIG. 7F), and a high level signal is output from the output terminal of the rebeat stop button 17 (FIG. 7B). Next, the first frame of the desired pattern is placed in the exposure section using an automatic search device or the like.

The operator correctly positions the frame in the copy frame 10 while observing the image of this frame on the screen, and presses the copy button 18 after completing the positioning. Command to start copying. When the copy button 18 is turned on, the image on the screen disappears.
The device transitions from the viewing state to the printer state. When the copy button 18 is turned on, a high-level copy command signal (
A) in FIG. 7 is output, and this signal activates the printer operation circuit 27 via the OR gate 20, whereby the image of the frame placed in the exposure section is exposed to the photoreceptor and the first copying operation is performed. be exposed. After exposure. The image is projected onto the screen again. Upon returning to the observation state, the printer operation circuit 27 outputs a high level termination signal (FIG. 7D), and this signal activates the transfer control circuit 40 via the OR gate 21. As a result, the film F is fed, and when the mark detector detects the mark of the second frame, the film feeding is stopped and a high level film stop signal (FIG. 7E) is output from this circuit 40. The timer circuit 28 is activated by this film stop signal. The timer circuit 28 generates a copy start signal (FIG. 7G) after a set time t1 after starting its operation. After replacing the image frame in the exposure section. The operator checks the display on the display section 19 until this copy start signal is issued, that is, within the set time t1, and confirms that the set time has elapsed.
Perform the positioning work of the th piece. The above-mentioned work is completed before the display on the display unit 19 reaches the set time. When the set time is displayed, the repeat stop switch 17 and the skip button 16 are off. Mode changeover switch 15
has been switched to repeat mode, the copy start signal from the timer circuit 28 causes AND gates 25 and 2 to be activated.
3 and 22 are opened, and the printer operating circuit 27 is activated again via the OR gate 20. A second copying operation is performed. After the second exposure, the film is fed again and the second
The third frame is automatically placed in the exposure section in place of the third frame.

Observe the image of the third piece on the screen. If it is not necessary to copy this third frame, the user looks at the display on the display section 19 and presses the copy skip button 16 before the timer circuit operates for the set time t1.

When the skip button 16 is turned on, the output terminal f of the skip circuit 30 becomes high level (FIG. 7 F'): When the skip button 16 is turned on after the third frame is placed in the exposure area, the timer circuit 28 is turned on. A copy start signal is generated, but since the AND gate 23 is closed due to the ON of the copy skip button 16, the printer operating circuit 27 does not operate, and continuous copying is temporarily interrupted. on the other hand.
Since the output terminal f of the skip circuit 30 is at a high level when the skip button is turned on, the AND gate 24 is opened by the copy start signal. The transfer control circuit 40 is operated via the OR gate 21, the motor 44 is driven, the film is transferred, the frame in the exposure section is replaced, and the fourth frame is placed in the exposure section.

After the piece exchange is completed. Retimer circuit 2 based on film stop signal
8 is activated. Therefore, by turning on the skip button 16, the transfer control circuit is activated and the mode is switched to a mode in which the original is exchanged without performing the next copying operation. When the AND gate 24 is opened, the skip circuit 30 is reset after a predetermined period of time via the delay circuit 29. Output terminal f becomes low level (Fig. 7F). As a result, the signal output from the timer circuit automatically switches to the original mode in which the copying operation is performed. Therefore, the operator is. After replacing the third piece with the fourth piece without copying it. It is only necessary to perform the necessary work for the next piece, that is, the fourth piece, within the set time t1 while watching the display on the display unit 19.

Furthermore, 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 unnecessary frames. After resetting the skip circuit 30. When the copy start signal is generated again from the timer circuit 28.
AND gates 25, 23, 22 open, or gate 2
The printer operation circuit 27 is activated via 0, and the third copying operation is performed.

From then on. The operator confirms the position of the image and the content of the image while looking at the display on the display unit 19. You can automatically copy each image at preset time intervals without pressing the copy button. (Hereinafter, this copying style will be referred to as "repeat copy") To stop rebeat copying, press the rebeat stop switch 17. AND gate 25 closes. Therefore, the copy start signal from the timer circuit 28 is not sent to the printer operation circuit, the next copying operation and image exchange are not performed, and the repeat copy ends.

Note that repeat copying can be similarly stopped by switching the repeat/manual mode changeover switch 15 to manual mode. When the mode changeover switch 15 is switched to manual mode, a copying operation is performed each time the operator presses the copy button 18. It can be used like a normal printer device. Experiments have shown that the time required to consider image content and position the image depends on the ability of the operator. It depends on your experience, the content of the image, etc. Generally, it is about 2 seconds.

Therefore, the set time t may be changed to an appropriate time by operating the copy cycle adjustment dial 14, depending on the skill level of the operator. If the operator is an experienced operator, the copying operation can be done in a short time by shortening the setting time to shorten the copying cycle, whereas if the operator is inexperienced, the setting time may be lengthened. As described above, according to the present invention, when multiple originals are automatically and continuously copied. When there is a document that does not need to be copied, repeat copying can be interrupted using the selection means, the document can be automatically replaced with the next document without being copied, and automatic continuous copying can be performed again from the next document. This simplifies the copying operation and allows the copying work to be done in a short time.

In addition, the operator does not have to press the Copy button every time a document is exchanged or every time copying is resumed after interrupting repeat copying. Operational hassles are eliminated.

Also, review the content of the manuscript and correct any bends in the manuscript. Alternatively, the automatic copying cycle can be arbitrarily set in consideration of the time required for adjusting the position of the original, etc., and the burden on the operator caused when making copies of a large number of originals can be reduced. Additionally, the copying process can be carried out in accordance with the elapse of the set time of the copying cycle, which prevents the accident of copying being started while the manuscript is being examined or positioned, thereby making a mistake in copying. Even operators who are not familiar with the system can perform copying operations with peace of mind. Also. It is also possible to easily decide whether or not it is okay to leave the copying machine when other errands are available. In addition. The present invention is applicable not only to microfilm reader printers but also to copying machines that use manuscripts such as documents and drawings. In addition, copying methods are not limited to electrophotography;
Methods such as silver halide photography and heat development photography can be applied.
