Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control mechanism in a copying machine having a manual paper feed mechanism for manually feeding copy paper, and more specifically, the present invention relates to a control mechanism in a copying machine having a manual paper feed mechanism for manually feeding copy paper, and more specifically, the present invention relates to a control mechanism in a copying machine having a manual paper feeding mechanism for manually feeding copy paper. Conventional technology relates to a control mechanism and mechanism that links and controls the manual feeding of copy paper, the document feeder, and the sorter when operating in a linked operation mode.In general, electrophotographic copying machines, etc. When copying by supplying copy paper, in addition to replacing the original on the document placement glass, it is necessary to insert the copy paper from the insertion slot each time a copy is made, so it is necessary to replace the original and press the print key. The operation is more complicated than in the case of automatic paper feeding, where copying can be performed simply by pressing . In addition, in most copying machines, the working positions for exchanging originals and manually inserting copy paper are different, and copying by hand is actually inefficient, making the above-mentioned sense of cumbersomeness even stronger for workers. It has become a thing.

On the other hand, a document conveying device for automating the operation of replacing the document on the document placement glass is disclosed in Japanese Patent Laid-Open No. 57-20126.
A number of methods have been proposed, such as Publication No. 0 and Japanese Unexamined Patent Publication No. 59-43755, but none of them provide any control to eliminate the above-mentioned complicated operations during manual copying. Not yet.

Further, when a large number of copies are to be made by manual paper feeding, it may be desirable to sort the copies after copying using a sorter. However, in conventional copying machines, there is no link between the manual paper feeding operation and the sorter operation, and even on copying machines equipped with a sorter, when manually feeding paper, the sorter mode is set to a non-sort mode in which no sorting or processing is performed. It was common to do so.

Therefore, copying by manual feeding, which involves sorting and processing,
Traditionally, this has been extremely troublesome.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems, namely, the troublesomeness of manual copying which involves sorting and processing.

Means for Solving the Problems As a means for solving the above-mentioned problems, the present invention provides a document transport device that transports a document to an exposure position and also discharges the document at the exposure position, and a document feeding device that feeds copy paper by hand. control of a copying machine equipped with a manual paper feeding mechanism for storing copies, and a sorter having a plurality of copy paper storage bins and sorting the copies by sequentially storing the copies after copying from a predetermined bin to other bins. The mechanism includes a paper feeding mode switching means for switching the copying machine to a manual paper feeding mode in which paper can be fed by the manual paper feeding mechanism, and a sorting process by the sorter in connection with the copying operation in the manual paper feeding mode. a signal output means for outputting a signal for operating the document feeder in the manual feed mode; and a signal output device for operating the document feeder when the signal is output to eject the document at the exposure position. and a second control means for setting a new document at the exposure position and for returning the sorter to a state in which sorting from the predetermined bins can be performed.

Operation In the above configuration, when performing manual feed copying for multiple originals, the paper feed mode switching means selects manual feed mode 1, sets the originals on the document feeder, and manually feeds the copy paper. The copy operation is executed by After copying, the copy sheets are sorted by a sorter. When you want to replace the original, or when the preset number of manual copies have been completed, the signal output means outputs a signal to operate the original transport device, a new original is automatically set at the exposure position, and the sorter returns to the home position. Return to position.

Example Embodiments of the present invention will be described below with reference to the drawings.

First, as shown in FIG.
Its configuration and operation will be schematically explained.

A photoreceptor drum ([) having a photoreceptor layer on its surface is supported at approximately the center of the main body of the copying machine (100) so as to be rotatable in the counterclockwise direction in the figure. Around the photoreceptor drum; [),
Main eraser lamp (2), sub charger (3)
), a sub-eraser lamp (4), a main charger (5), a developing device (6), a transfer charger (7), a separation charger (8), and a cleaning device (9) are arranged in this order. The photosensitive drum ([) is sensitized and charged by passing through the eraser lamps (2) and (4) and the chargers (3) and (5), and receives image exposure from the scanning optical system (10). An electrostatic latent image is formed on the surface.

The optical system (10) is installed below the original glass (16i) so that the original image can be scanned. The light source (1η), the movable mirror (11) has a circumferential velocity (V) of the photoreceptor drum ([)
(constant regardless of the same magnification or variable magnification) versus v/n (however, n
: copy magnification) to the left, and the movable mirror t1z
-ua is driven to move to the left at a speed of v/2n.

Copy paper is fed into the machine by an automatic paper feed mechanism or manual paper feed mechanism (30) provided on the left side of the main body of the copier (100) in the figure, and is temporarily stopped by a timing roller (21). The image formed on the photoreceptor drum ([) is sent to the transfer section in synchronization with the image formed on the photoreceptor drum ([), and transferred to the transfer charger (
7) receives the toner image transfer, and the separation charger (8)
The image is separated from the surface of the photoreceptor drum ([), and sent to the fixing device (2) by the conveyor belt (2), where the image is fixed and conveyed to the sorter (to). After the i-transfer, the photosensitive drum ([) is cleaned of residual toner and electric charge by a cleaning device (9) and an eraser (2), and is ready for the next copying process.

Either the automatic paper feed mechanism (20) or the manual paper feed mechanism (2) is selectively used. The switching is performed, for example, by detecting opening/closing of a manual feed table (31) that also serves as a guide for manually fed copy paper using a sensor (SEL). Another method is to use a sensor (sE2) to detect when a copy paper is inserted from the manual insertion slot (■) in a state where paper can be fed, and to drive the paper feed roller (2) of the manual copy paper and copy the paper. It is also possible to start the operation.

In the case of automatic paper feeding, the image forming system including the photosensitive drum ([) and the scanning optical system 00) are activated by operating the print key (71) (see Figure 2) that starts the copying operation of the copying machine (100). and start. A paper feed signal is output as the scanning optical system (10) moves, and the paper feed roller a) is driven by this paper feed signal to feed copy paper in synchronization with the image forming operation.

On the other hand, in the case of manual paper feeding, when a copy paper is inserted from the manual insertion slot (2) and a sensor (SE2) detects this, the manual paper feed roller (2) rotates and feeds the copy paper into the machine. At the same time or with a slight delay, the photosensitive drum ([) and the scanning optical system (10) start in the same manner as when the print key is operated as described above.

Then, the manually fed copy paper is temporarily stopped and waiting at the conveyance roller (351), and the conveyance roller (g) is rotated by the output of the above-mentioned paper feed signal, thereby being fed into the machine.

The switch (SW) provided near the manual feed door (3D) is a document exchange switch for operating the automatic document feeder (200) and exchanging documents, as described later. It is preferable that SW) be located at the back of the manual feed table (31) when it is stored so that it can be operated by the user only in the manual feed mode.

On the other hand, automatic document feeder (hereinafter referred to as ADF) (2
00) is removably installed on the top surface of the main body of the copying machine (100). When the ADF (200) is electrically connected to the copy @ (100) main unit and installed in the specified position, the
The controls of the DF (200) and the copier (100) are associated with each other, and the operation mode of the copier (100) or the ADF mode is switched. What is ADF mode? Copy machine (100)
When the print key c71) provided on the ADF (
The document feed roller (201) and document transport belt of 200) start operating, and feed the document placed on the document tray (203) along the top surface of the document placement glass of the copying machine (1,00). , after the leading edge passes the document sensor (SEO), it is stopped at a predetermined position after a predetermined time, and the AD
A start signal is output from F (200) to the copying machine (100) to start the above-described copying operation. In addition, when the final scanning movement for the original is completed in ADF mode, copy fi (100) is moved to ADF (20).
0), the ADF (200) discharges the original onto the paper discharge tray (204). At this time, if the next original is on the original tray (203), the next original is also conveyed to a predetermined position at the same time as the paper is ejected.

In addition, in the case of copying by manual paper feeding, even before the final scanning movement for the original is completed, if the original replacement request switch (SW) is operated, the original on the original glass is ejected. , and the next original is set in the normal position. The operation of the ADF (200) when the original exchange request switch (SW) is operated is performed after the end of scanning if scanning is in progress, or immediately if scanning is not in progress.

The example sorter is installed in a paper discharge section of a copying machine (100).

When the example sorter is electrically connected to the main body of the copier (100), the controls of the example sorter and the copier (100) are associated with each other. Specifically, when multi-copy is executed when the mode of the sorter (to) is the sort mode, the deflection unit (241) sequentially descends from the position facing the topmost bin (242a) to the bin (242). Insert the copy paper one sheet at a time. When the multi-copying of the original is completed, the deflection unit (241) moves the topmost bin (242) again.
It is moved to the position corresponding to a) and waits until copying of the next original starts.

FIG. 9 is a flowchart generally showing the operation control of the sorter. In step s1, initial settings of the CPU (not shown) which controls the operation of the sorter are performed, and the deflection unit (241) is set at the position relative to the topmost bin (242a). In step S2, the copying machine (10
This is a sort mode control subroutine that executes control for storing copy sheets ejected from 0) into a sorter in a sort mode, and the details thereof will be explained with reference to FIG. Step S3 executes control of modes other than sort mode, such as stack mode and grouping mode.

In step S4, it is determined whether a timer for making the processing time of the l routine constant is terminated.

FIG. 10 is a flowchart showing details of the sort mode control subroutine. The sort mode is a mode in which, when multi-copying is executed, successively ejected copy sheets are accommodated one by one in each bin (242).

In steps 5201-5202, the copy paper is transferred to the copy machine (1
The bin number is incremented at the timing when the bin is discharged from 00). That is, the deflection unit (241) has bin number "1".
When the copy paper is in the position corresponding to the bin in the copier (
100), the bin number is set to "2", and after ejecting the copy paper into the bin with the bin number "1", the deflection unit (241) is set to the incremented bin number "2". Move one bottle to the corresponding position.

In step 5203, it is determined whether the ADF start signal is rlJ, and if it is "1", the step knob 520
The process proceeds to step 5204 where the bin number is set to "1", while if it is "0", the process proceeds to step 5204. ADF start signal is A
When the document exchange request switch (SW) is pressed in the manual feeding mode using the DF (200), or when the AD
When the multi-copy using F(200) is completed, "

In step 5204, it is determined whether or not the number of copies set in advance using the numeric keypad has been ejected. If the set number of sheets has been ejected, the process advances to step 5205 and the bin number is set to "
1”. On the other hand, if the set number of sheets have not been ejected, the process advances to step 5206, where it is determined whether the bin number is one greater than the maximum number of bins, and if it is less than the maximum number of bins, the process returns and the maximum number of bins is If the number is one greater than , the process advances to step 5205.

That is, in the above mode, by moving the deflection unit (241), the set number of continuously ejected copy sheets are stored one by one from the topmost bin (242a), and the set number of sheets are stored one by one. When accommodated, the deflection unit (241)
is returned to the position corresponding to the top bin (2423).Also, when the set number of sheets is greater than the number of bins in the sorter (to), the sheets are stored in the bottom bin (242b) and then returned to the top bin (242b). 242a) and repeat until the set number of copy sheets has been stored.Then,
When the set number of copy sheets has been stored, the deflection unit (241
) is returned to the position corresponding to the topmost bin (242a).

Note that such control can be executed when multi-copy is set using the numeric keypad, regardless of whether the mode is manual paper feeding mode or automatic paper feeding mode. Furthermore, ADF (
200), when the document exchange request switch (SW) is pressed, the deflection section (241) of the sorter example is returned to the position corresponding to the topmost bin (242a), and the next The document is now ready for sorting.

In the above embodiment, when performing manual feed multi-copy for multiple originals, the manual feed door is used! 31J and set the copying machine (100) to manual paper feed mode, then
Place the original on the original tray (203) of F (200) and set the number of copies using the numeric keys on the operation panel. When the first copy sheet in the manual feed mode is inserted, the ADF (200) operates and the original is set in a fixed position on the original glass, and the 72nd sheet is set in advance using the numeric keypad when manual feeding starts. Copying is performed without operating the ADF (200) for up to the number of sheets manually fed. When manual copying of the number of sheets set in advance using the numeric keypad is completed, the ADF (200) operates to change the original, and a state is reached in which manual multi-copying of a new original is possible.

If you want to change the document currently being copied when manual multi-copying is in progress and the number of copies set in advance using the numeric keypad has not been completed, press the document exchange request switch (S
By pressing W), manual multi-copying can be interrupted and the document can be changed by operating the ADF (200).

Further, manual multi-copy paper can be sorted in sort mode using a sorter.

Furthermore, by pressing the document exchange request switch (SW) during manual multi-copying using the AD F (200) and when the sorter is in sort mode, the document is changed and the deflection unit (241) of the sorter is pressed. can be returned to the position corresponding to the topmost bin (242a) to prepare for sorting the next document.

''■■ Round ball As is clear from the above description, the control mechanism of the copying machine according to the present invention can facilitate the operation of setting a document at the exposure position during manual copying. Furthermore, by manually inputting the number of multi-copy sheets in manual copying using the numeric keypad and automatically operating the document feeder when the number of copies has been completed, the user is completely free from the operation of exchanging documents. In addition, by providing a document exchange request switch, manual multi-copying can be stopped at any time and the document can be replaced, and the flexibility of multi-copying can be expanded.
