〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an embodiment of a document handling apparatus (hereinafter referred to as a DF) among copying apparatuses to which the present invention can be applied. In the drawing, reference numeral 1 denotes an entrance tray for stacking sheet documents, and a sheet document 2 on the entrance tray 1 is placed with its lower side in the figure facing up. The DF entrance sensor 3 for detecting the first document is a reflection type sensor for detecting the front and rear ends of the sheet document, and the feed rollers 4 and 5 are pressed against each other to pinch and convey the sheet document. Reference numeral 6 denotes a stop for preventing the original from being fed onto the platen glass 10, which is released by the operation of the DF inlet stop solenoid 21 to enable feeding. The full-surface belt 7 is an endless belt having a width large enough to cover the entire surface of the sheet document, and has a sufficient friction coefficient such that the document can be conveyed by sliding the document on the document glass 10 by frictional force. The belt 7 is wrapped around the driving roller 8 and the turn roller 9 so that the entire belt 7 and the driving roller 8 do not slip. Further, the discharge roller 11 is in pressure contact with the entire surface of the belt, and the document discharged from the document glass 10 is sandwiched and conveyed. The DF exit sensor 13 for detecting the document detects the leading edge of the document with a reflection type sensor. Is stopped and then reversely driven. When the DF exit sensor 13 detects the trailing edge of the document, the document is stopped at a predetermined position.

On the other hand, a well-known digitizer is provided above the DF according to the embodiment of the present invention.
26, and a digitizer cover 27 that covers the entire surface of the digitizer is mounted on the upper part. And an open / close detection sensor that detects the open / close of this cover
28 is attached, and plays an effective role in mode switching and the like described later. In the upper right part of the DF, there is a digitizer feed port for feeding the original on the digitizer. When the cover is closed, it is hidden, but appears when the cover is opened. The digitizer feed port has a digitizer entrance detection sensor 22 for detecting a document stacked on the digitizer surface, and a reflection type sensor is used. Then, the feed rollers 23 and 24 are pressed against each other to pinch and convey the sheet document. Reference numeral 25 denotes a stop for preventing the original from being fed from the digitizer feed port onto the platen glass. The stop is released by the operation of the digitizer inlet stop solenoid 29 to enable the feed. The document sent out from the digitizer sheet feeding port by the conveying rollers 23 and 24 is sent along the guide plate, and is sent onto the platen glass from the right end of the above-mentioned entire belt.

All the rollers and the entire belt are driven by motors.
A clock disk, which is driven by 19 and generates a clock pulse at the time of rotation, and a sensor 20 are provided, and the operation of the DF is controlled by the clock. After the exposure operation is completed, the document sent out by the discharge roller 11 and the entire surface belt 7 is switched in discharge direction by a discharge flapper 30, and is discharged to a discharge tray 32 provided on the left side of the DF by turning on a flapper SL31 for moving the original. And loaded sequentially. Fratzpa SL31
Is turned off, the delivery rollers 1
The sheets are discharged by 5, 16 and sequentially loaded on the digitizer cover.

FIG. 2-1 is a schematic view of a digitizer section according to the embodiment of the present invention. This is constituted by one sheet-like resistor 50 for reading the position in the horizontal direction (X direction) and the position in the vertical direction (Y direction), respectively, and a lead pen switch (SW) 51. And the sheet-like resistor 50 is placed not only under the sheet, but also under the keys such as the clear key 52, the registration key 53, the continuous designation key 54, etc., and set by the pen SW 51 as described later. A voltage is output depending on the position, and the voltage is read as the set value of the area or the key.

The operator places the manuscript face up on the low antibody 50 and sets the manuscript to the upper right corner. By pressing two points of the area specified by the pen SW 51, for example, the points A, A 'or B, B', the area of ABA-B'-A is specified, and the registration key 53 described later is pressed. By pressing with pen SW51, the area designation is set,
For example, a trimming function and an image conversion function operate at the time of copying, and a copy as shown in FIG. 2-2 is output.

FIG. 3 is a block diagram showing the control unit of the DF and the copying machine. In the figure, a controller is a well-known micro computer (hereinafter referred to as a microcomputer), and accesses a RAM I / O by a program stored in an internal ROM. The output signal to the DF section is turned on / off (on / off) through the driver through the above-mentioned respective loads, that is, the normal rotation and reverse rotation signals of the drive motor, the DF entrance stop SL, the digitizer entrance stop SL and the discharge flapper SL. As input signals, the aforementioned sensors, that is, the DF entrance sensor, DF exit sensor, digitizer entrance sensor, digitizer open / close sensor, and clock pulse signal are inputted via buffers. Further, as an output signal to the digitizer, there is an X / Y application switching signal for switching the applied voltage to the digitizer electrode, and when "L", X-axis application "H" switches to Y-axis application. As input signals, a lead pen signal that is turned on when the lead pen is pressed against the digitizer electrode surface, and an X-axis input voltage signal and a Y-axis input voltage signal that input analog signals output according to the pressed position in the X / Y-axis directions, respectively. is there.
Further, an input / output signal is output to each control unit of the copying machine.

FIG. 4 is a detailed flowchart for setting the digitizer in the embodiment of the present invention. As described above, when the user presses the lead pen against the electrode surface of the digitizer to specify an area, the system waits for the lead pen signal for detecting the pressing of the lead pen 51 to be turned on (step 101). As soon as the ON signal is input, the voltage applied to the electrode is specified on the X axis, and the voltage generated according to the pressed position, that is, the X axis input voltage is AD
The data is converted and stored in (X-BuF) in the RAM (step 102).
Next, the applied voltage is switched to the Y-axis designation, and the input voltage is similarly stored in (Y-BuF) (step 103). And (Y-Bu
The data of F) is compared with the value of MAX in a predetermined area to determine whether the data is in or outside the area (step 104). If it is within the area, the area designation data address (X-2
nd) The contents of (X-1st) and (Y-1st) are shifted to (Y-2nd), and the data (X-BuF) and (Y-BuF) captured this time are converted to (X-1st) and (Y-1st). , The coordinates of the designated area are refreshed, and two points of data are always stored. In this way, even if coordinates are sequentially designated, the latest data is always available. If it is out of the area in the above-mentioned step 104, a search is performed to determine whether or not the key is a mode setting key. In step 106, it is checked whether or not the (X-BuF) data at that time is a predetermined clear key voltage value, and a registration flag and a continuous flag described later are cleared. In step 107, (Y-BuF) is compared with the registration key voltage value, and if they are equal, the registration flag is set. The digitizer area setting is completed by pressing the registration key. At the time of starting copying, it is determined whether or not the digitizer area designation is set.

Further, in step 108, the data of (X-BuF) is compared with the continuous designated key voltage value, and if they are equal, a continuous flag and a registration flag as described later are set.

FIG. 5 is a detailed flowchart of the operation of the DF according to the embodiment of the present invention. In the flow, first, the opening / closing of the DF digitizer cover is detected, and it is determined whether the mode is the digitizer mode or the DF mode (step 201). In the open state, the digitizer mode is set, and the process proceeds to step 202. At this time, the digitizer setting is accepted for the first time, and the process stands by while processing the digitizer setting Sub until the registration flag for judging the completion of the setting is set. When the setting is completed, it is checked whether or not the original is set in the digitizer entrance sensor, so that the feeding operation of the original is prohibited unless the digitizer is set (step 203).

On the other hand, when the digitizer cover is closed in step 201, the normal DF mode is set, and the process proceeds to step 204, where the above-described registration flag and a continuous flag described later are cleared. This means that a clear function for canceling the setting of the digitizer equivalent to pressing the clear key in the cover closed state is provided. And
In step 205, the document feeding operation is started by checking whether a document is set in the DF entrance sensor. The determination in step 201 is that only the digitizer paper feed port is selected if the document feed port is in the digitizer cover open state, and if the cover is closed, only the DF paper feed port is selected. With these functions, for example, if the user wants to use a digitizer, there is an effect that the operation of opening the cover → digitizer setting → feeding can be smoothly performed.

In the digitizer mode, digitizer feed processing and resist processing in step 206 are performed, and the digitizer is stopped at a predetermined position on the platen glass from the digitizer opening. Process and stop on platen glass from DF mouth.

After the stop, the copying operation is started. Naturally, in the digitizer mode, the area specifying copying operation is performed (step 20).
8) In the DF mode, a normal copy operation is performed (step 212). Particularly, in the digitizer mode, the registration flag is cleared once (step 207), and then the area designation copy operation is started. Since the registration flag is set in the above-described step 202, the feeding of the next original is permitted. In other words, it is normal usage to set the digitizer once for one document, and if the user overwhelms the setting of the next document, it will not feed it, preventing mistakes effective. And step208
In step 209, the digitizer setting SuB for the next document is processed until the registration flag is set, and the setting of the area designation is permitted while waiting for the end during the copying operation. This means that the next area specification is permitted during the copy, and the function is greatly improved from the conventional state where the area specification is accepted only in the standby state, and the total efficiency of the area specification copy is improved. Leads to. When the continuation flag is set by the continuation designation key, the designated area is continuously set for the continuous originals. That is, in step 207, if there is a continuous flag, the registration flag is not cleared.
9 prohibits new digitizer settings during copying and ste
Since the setting of the digitizer at the time of standby is also prohibited in p202, the above operation is performed. The clearing of the continuous flag is performed by closing the digitizer cover (stpe 204) or pressing the clear key (stpe 106).

[Effect] As described above, according to the present invention, the first control means for registering an area by executing a program for causing the storage means to store the area data representing the area specified by the area specifying means is provided. If a first mode for performing area designation copying according to common area data is specified for a plurality of documents sequentially fed, the program of the first control means is applied to the fed documents. After performing the area designation copy corresponding to the area registered by the execution, the area designation corresponding to the same area as the previous document is made for the next fed document without executing the program of the first control means. Since the copying is performed, if the first mode is set, the area specification is performed every time one original is copied when the area specification copy according to the common area is performed for a plurality of originals. Waiting It is not that become a state in the process would stop, thus improving the operability. When the second mode for performing the area designation copy corresponding to the area data corresponding to each of the documents sequentially fed is designated, the fed document is registered by executing the program of the first control means. After the area designation copy corresponding to the set area is performed, the program of the first control means is executed to register a new area, and the next fed document is set according to the newly registered area. The specified area is copied.
If you set the mode, when you try to perform area designated copy according to the area corresponding to each document, it will be in the area designation waiting state every time one document is copied,
It is possible to surely specify the area for each document and to specify the area.
