If the 3rd picture image is unnecessary to copy, the operator skips the image by depressing a skip button.

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 1 song.
As shown in Figures (A), (B), and (C), there are various types of roll-shaped films, such as Fleshish Film F and Aperture Card F. Roll~a4. bl
. . . are arranged in a - column, and a search or positioning mark M is provided on the side of each piece. The Fish Island film F is a rectangular film in which a large number of image frames a, ~&4*t)1... are arranged in a grid pattern, and the aperture card F is a part of the aperture of the card. A film with one or more frames is attached to the top. 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 microfilm.For example, in the roll film Fly Fic2 film F shown in tdg1 figure,
4 pieces in a row 'l e at s as # JL
The images of No. 4 are related and constitute information for each friend, and the images of 4 are related and constitute information for one unit of information. When copying a plurality of related image frames in succession, while the printer finishes one copying operation and moves on to the next copying operation, the operator needs to change the location where the film was fed and the aperture card. 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. was there.

Also, there is a known device in which when you set the number of continuous copies by setting the dial and press the copy button, the copying operation starts and the set number of copies are automatically made continuously. The copy button has to be operated every time the copy is changed, which is troublesome and takes a long time to complete the copying process.Furthermore, the operator cannot leave the apparatus while copying.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a copying apparatus which eliminates the above-mentioned disadvantages and can automatically make a predetermined number of copies of each document.

The present invention will be explained below with reference to the drawings.

FIG. 2 shows a reader printer using a rolled film to which the present invention is applied, and the entire device is composed of a printer device 1, an operating device 2, and an observation device 3.

The printer device 1 is composed of an electrophotographic photoreceptor, an exposure means, a charging means, a developing means, a transfer means, a copying material feeding means, a drying and fixing means, and the like. Such a printer device is well known, for example, from TF41, 1982-8247, and so a description thereof will be omitted.

A roll-shaped microfilm F is stretched between two reels 4.5, and is transferred from the left reel V to the right reel 5 by rotation of the feed roller 6.7. The microfilm F is illuminated by a lamp in an exposure section formed at the top of the printer device I. The image of the illuminated film is selectively projected by the projection lens 8 onto either the photoreceptor of the printer device 1 or the screen 9 of the viewing device 3. This selection is performed by rotating a mirror (not shown) placed on the optical axis of the projection lens 80. The screen 9 is not a transmissive type screen, and is provided with a frame 1G that serves as an index for positioning the image on the film at a predetermined position. The observation device 3 is composed of optical means such as a mirror. Such an observation device was developed, for example, by the
1-23174, 41) JP-A-50-80124, etc., and therefore the explanation thereof will be omitted. The front panel 11 of the operating device 2 includes a power switch 12 for supplying power to the printer device, etc., a copy density adjustment dial 13, a copy cycle adjustment dial 14, a repeat/- mode selection switch 15, and a copy skip button 16. , a repeat stop button 17, a copy button 18, and a copy number setting dial 19 are provided.

FIG. 3 shows a printer control section for controlling the operation of the printer device 1. As shown in FIG. In Figure 3, 20
．． 21 is an OR gate, 22, 23, 24, 25 is an AND gate, 26 is an inverter, and 27 is a printer control circuit.

As shown in FIG. 4, the printer control circuit 27 includes a printer drive control circuit 80 that operates various processing means of the printer device l in a predetermined time order according to a predetermined sequence, and a counter 81 that counts the number of copying operations.
Counter 81 count value and number of copies setting dial 19
and a comparison circuit 82 that compares the set value of .

The printer drive circuit 81 outputs a high-level end signal from the output terminal a every time one copy material is ejected from the printer device 1. This end signal is output as a signal indicating that the exposure scanning of the frame in the exposure section has been completed. For example, in the case of a scanning method in which the original is scanned by moving the original table holding the microfilm, when the scanning of the image is finished by moving the original table and the original is returned to the home position 1, or when the microfilm is fixed. In the case of a scanning method in which the document is scanned by moving a mirror, when the image is scanned by moving the mirror and the mirror returns to the home position, the position of the movable document table or exciter mirror is set using a micro switch. etc., and the end signal is obtained from this microswitch. It should be noted that this command may be obtained in conjunction with the operation of the developing means, the IIi&'4 means, the copying material feeding means, or the like.

The counter 81 calculates the number of additional stitches of the end signal V. When the number of needles on the counter 81 matches the number of copies set by the number of copies setting dial 19, the comparison circuit 82 outputs a high level match signal from the output terminal a.
The IC signal disables the shibinter drive wJ control circuit 80, and the p1 counter 81 is reset to return to its original state. Therefore, the printer drive control circuit 80 is connected to the OR gate 2.
When a high-level copy start signal is sent, the printer operates continuously until the set number of copies is obtained.

In Figure 3, reference numeral 40 indicates a feed mtnetg1 path that controls the feed of the film F, and operates to feed the film when it receives a high level signal from the OR gate 21.

As shown in FIG. 5, the feed control circuit 40 includes a light source 41 that illuminates the mark M on the film F, a light receiving element 42 that detects the mark M, a mark detection circuit 43, a feed roller 6,
It is composed of a motor 44 that rotates the motor 7.

When a high level signal is received from the feed control circuit 40F1 (or game) 21, the motor 44 is driven and the feed rollers 6, 7 are driven.
The microfilm F is fed by rotating the light receiving element 4.
When the mark of the next frame is detected, the motor 44 is stopped and a film stop signal of noi level is outputted from the output terminal. 'This allows the film frames to be replaced automatically in the exposure section.

In FIG. 3, numeral 28 indicates a timer circuit, which operates 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 signal is sent from the output terminal C. Generates a start signal, finishes measuring time and becomes inactive.

Figure 6 shows a specific example of a timer circuit, 50 is a flip-flop circuit, 51 is a variable resistor, which is connected to the copy cycle adjustment dial 14, and by operating this dial, the variable resistance can be adjusted. The resistance value of the device 51 changes to adjust the set time. 52 and 53 are diodes, 54 are resistors, 55 are capacitors, and 56 and 57 are inverters.

FIG. 7 shows waveforms at each point A1 to A40 of the timer circuit, and the waveform lines AI, At, AH, A4 in FIG.
represents the waveform of each point with the same sign as this! l and 's indicate the set time of the timer circuit, and t and #i indicate the pulse width of the microcopy start signal.

As a timer, a combination of a cam and a microswitch with different set times may be used to adjust the set time, or various other known timers may be used.

In FIG. 3, 29 is a delay circuit, and 30 is a skip circuit. The skip circuit 30 is composed of a tree block flop circuit, and its set input terminal d is connected to the copy skip button 16, and its reset input terminal is connected to the copy skip button 16.・
is connected to the output terminal of the AND gate 24 via the slow arc circuit 29, and the set output terminal fKfi inverter 241
It is connected to the L1 input cursor.oo Next, check the operation of the above reader-printer according to the time chart in figure -8 and 111! - to do.

First, the power switch 12' is turned on, and the repeat/Mayu Island mode selector switch 15 is set to the repeat mode in order to obtain multiple copies of v-1.

Due to this, a high level signal is input to the AND gate 22 (Q one input 1,000 g).Meanwhile, the copy skip button 16 and repeat stop button/17 are turned off.At this time, the output terminal of the skip circuit 30 The configuration is such that a low level signal is output from the output terminal (Fig. 8F), and a high level signal is output from the output terminal of the repeat stop button 17 (Fig. 8B).

Next, the first frame of one unit of desired information is placed in the exposure section using an automatic @ placement device or the like. In operation t, observe the image of this frame on the screen and then position it correctly in the copy frame 1G.

Then make the necessary copies of the positioned images! Set L using the setting dial 19 and press the 7J island et al. copy button 18. i on the screen by turning on the copy button 18
l! li 葎 disappears, and 4 lines appear in the printer state.

When the copy button 71B is turned on, a high-level copy start signal (stripes 8-m) is output, and this signal causes the OR gate 2 to be activated.
Printer drive via 0 kIJi111111gl road 8
0 is activated, mm of the piece placed in Mugenfu due to revenge
is exposed to the photoreceptor, and the first copying operation is performed (stripes 8 and C). The burr/tor drive side control 41l-80 is set.
The printer device is operated repeatedly in the trench where a copy of the fca is obtained, and when a signal is sent from the comparator circuit 82, it stops operating.

After the set number of times (4m Q multiplications) have been performed, a high-level stroke signal (D in Fig. 8) is output from the comparator circuit 82.

When this signal is output, the image is projected on the screen again and the image becomes ``11 towns''.At the same time, the feed control circuit 4G is activated by the signal 21 (or game by the g number) and the motor is activated. 44 is running. Film F or forward # due to sharpness
When the mark detector detects the mark L of the frame O, the film stops and the feed control circuit 40 outputs a high level refilm stop signal (eighth frame E). The Eta timer circuit 28 or hlJ8 is made to stop this ID film. The timer circuit 28 generates a copy start signal (FIG. 8G) after a set time (t,).

After exchanging the drawing pieces in the exposure section, the maintenance 41 performs the positioning of the second inspection piece, etc., on the exposure S, at the threshold before the start of copying, that is, within the time t. Made by MJ
Do k. When the set time VC is reached, the repeat stop switch 17 and the skip button 16 are off, and the mode changeover switch 15 is set to repeat mode, so the timer circuit 28ph is output and the AND gate 25° 23 is output from the timer circuit 28ph. .22 is one piece, splitter drive control 1m via OR gate 20! 80 is entered and the copying movement f'' of the second piece is performed.Similarly to the above, when a copy of the second piece is obtained, 3 is placed in place of the second piece Q.
The second - is automatically placed in the exposed area.

If there is no need to copy the third piece, use a timer circuit or set time t.

Before actuation, the operator presses the copy skip button 16. Skip button 160 is turned on & (-2 output terminal 1μ of skip circuit 30) becomes level (No. 81F).

After the third frame is placed in the 4-light section and the skip button 16 is turned on, the copy-#I scratch signal is generated from the timer circuit 28, or the AND gate 23 is closed due to the skip circuit 716 being turned on. Therefore, the printer drive and control circuit 801 does not operate, and continuous copying is temporarily interrupted.

On the other hand, when the subbutton is turned on, the output of the skip circuit 30 becomes high level, so the copy start signal opens the cyan gate 24, and the OR gate 211!
The compression-tit 11-path 40 is operated via the motor 4.
4 is *1lkil and Ful (rum is a transfer stone and 1ljt,
The pieces in the section are exchanged, and the 4th O- or tilit is placed in the exposed section.
I can get stoned. -55 The timer circuit 28 is activated by the film stop number 11. Therefore, when the skip button 16 is turned on, the subject is not photographed for 19 days, the feed ItIIJ #1 path is activated, and the mode is switched to the seventh mode for exchanging the original.

The output terminal f becomes low level (No. 7-F), and as a result, the mode is automatically switched to the original mode in which the copying operation is performed using the No. 01 output from the timer circuit.

Therefore, in operation 4, it is sufficient to replace the 311th piece with the 4th piece without copying it, and after π, perform the necessary work on the -1 piece, that is, the 4th piece, within the fixed time C8.

Furthermore, if you do not copy the 4th one or more dC) several pieces, you cannot copy! All you have to do is press the skip button x 6 km repeatedly at appropriate intervals.

After the skip time wI30 is reset, when the copy 1 start signal is generated again from the timer circuit 28, the AND gate 25
, 23, and 22 are activated, the printer drive control 141 circuit 80 is activated via the OR game 20, and a 6-input operation is performed for the 4th scan Q piece. Thereafter, the operator can confirm the position of the image and the content of the image, and then automatically copy the image for each iron within a preset period of time without pressing the copy button (hereinafter referred to as "copy"). This is called a ``repeat copy''.

To stop repeat copying, when the repeat stop switch 17 is pressed, the AND gate 25 closes and the copy start signal is not sent to the printer drive circuit 28t), and the next copying operation and - Repeat copy ends without image exchange.

Note that repeat copying can be similarly stopped by switching the repeat/manual mode changeover switch 15 to the manual mode 19.

Mode changeover switch 15! When switching to the digital mode, the copying operation is performed immediately after pressing the copy button 18, and the IIC can be used in the same way as a normal printer.

In the experiment, Jb time 1-, which is based on the sameness examination of the meme and the 1st arm and the positioning of the ll1il image, differs depending on the operator's total effort, the rope, or the contents of the m image, but in general, it is possible to do it in 2 seconds. be.

Therefore, adjust the subject cycle adjustment dial 14 according to the skill level of each work and check the prescribed time.

It is necessary to change the ML for an appropriate amount of time. Shusaku Ministry is II! &
If you are using embroidery, you can shorten the setting time and shorten the capture cycle to make the copy work 1 or short poem 1-; if you are an inexperienced operator, you can lengthen the copy time 14. .

As described above, according to the present invention, when a plurality of originals are automatically and continuously copied, if there is a JIA error due to poor copying, the repeat copying is interrupted by the appropriate translation means, and this original is...
It is possible to self-excitedly change the original to the next manuscript and perform automatic continuous copying again from the next manuscript, and the number of copies is 1114L.
Therefore, copying can be done in a short time. l
Did the operator perform a copy operation after an interruption, such as a repeat copy, each time a copy is performed? There is no need to press the copy button on the 4th page, which eliminates operational hassles. In addition, the self-excited copying cycle can be arbitrarily set by considering the content of the manuscript, the curvature of the manuscript, the position of the manuscript, 1llIiIIE, etc., and the self-excited copying cycle can be set arbitrarily. @
can be destroyed.

If you set up a copying cycle and proceed with the copying work in time with the passing of time 1-1, the copying operation will start during the examination or positioning of the silkworms in pregnancy, Mi, and 4, resulting in mistakes being made.
Therefore, even operators who are not familiar with the machine can perform copying operations with peace of mind.

Incident #4 can be applied not only to microfilm reader printers but also to copying machines that use documents and single-sided originals, and the subject method is not limited to electronic photography, but can also be applied to steel ingot photography, thermal ingot photography, etc. The method described above can also be applied.
