Detailed Description of the Invention 3. Detailed Description of the Invention [Technical Field] The present invention relates to a document handling device that feeds a document to a predetermined position.

[Prior Art] Generally, an image forming apparatus such as a copying machine is sometimes used with an additional document handling device that feeds the document to a predetermined position such as an exposure position.

In recent years, R
A system has been added that specifies a certain area of a document and extracts or extracts only the specified area to create a copy. At that time, when specifying the area, there are methods in which the XY coordinates are entered manually, and methods in which the region is specified manually using a well-known digitizer device.

However, conventionally, the above-mentioned digitizer device is known to be set above a presser plate on the platen glass of a copying machine, but in this case, the operator manually opens the presser plate after using the digitizer and removes the document. It was necessary to take the trouble of re-placing the platen on the platen glass.

Furthermore, when the above-mentioned document handling device is installed in a copying machine, there is no need to install a digitizer device, and the operator is required to place the document on an external stand or the like, and the operator has to replace the document each time. However, there was also the problem that the configuration was large-scale.

[Objective] The present invention has been made in view of the above points, and its object is to provide a document handling device having a simple configuration, improved operability, and a function of specifying an arbitrary area of a document. It is in.

〔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 device (hereinafter referred to as DF) among copying apparatuses to which the present invention can be applied. In the figure, reference numeral 1 denotes an entrance tray on which sheet originals are loaded, and sheet originals 2 are placed on the artificial tray 1 with the lower side in the figure facing up. The first document detection DF input sensor 3 is a reflective sensor that detects the leading and trailing edges of the sheet document, and the feed rollers 4 and 5 press against each other to sandwich and convey the sheet document. 6 is a stopper that prevents the document from being fed onto the platen gas lO, and is a lost flange solenoid 2 that enters the DF.
It is released by the action of step 1 and feeding is enabled. The full-surface belt 7 is an endless belt with a width that is large enough to cover the entire surface of the sheet document, and the surface of the belt is attached to the document glass IO using frictional force.
It has a sufficient coefficient of friction so that it can be conveyed by sliding on it, and is wrapped around the drive roller 8 and turn roller 9, and is configured to prevent the entire surface belt 7 and the drive roller 8 from slipping. Further, the ejection roller 11 is in pressure contact with the entire belt, and conveys the original ejected from the original glass IO by sandwiching it, and once the DF output sensor 13 for detecting the original detects the leading edge of the original with a reflective sensor, once the original is □ The full-surface belt is stopped and run in reverse, and when the DF output sensor 13 detects the trailing edge of the document, it is stopped at a predetermined position.

On the other hand, a well-known digitizer 26 is mounted on the top of the DF of the present invention, and a digitizer cover 27 covering the entire surface of the digitizer is placed on top. Opening/closing detection sensor 2 detects opening/closing of this cover.
8 is attached, and plays an effective role in mode switching, etc., which will be described later. In addition, there is a digitizer paper feed port in the upper right corner of this DF that feeds the document on the digitizer.It is hidden when the cover is closed, but is exposed when the cover is opened. This digitizer paper feed port has a digitizer entrance detection sensor 22 that detects the document stacked on the digitizer surface, and uses a reflective sensor. and feed roller 23. 24 press against each other to sandwich and convey the sheet original.

A stopper 25 prevents the document from being fed from the digitizer paper feed port onto the platen gas, and is released by the operation of the digitizer inlet stopper solenoid 29 to enable feeding. From the digitizer paper feed port to the transport roller 23. 24
The document sent out is sent along the guide plate and is sent onto the platen glass from the right end of the above-mentioned full-surface belt.

Motor 1 drives all the rollers and the entire belt.
A clock disk and a sensor 20 are provided which are driven by a clock disk 9 and which generate clock pulses when rotating, and which control the operation of the DF. After the exposure operation is completed, the discharge roller 11. The document sent out by the full-surface belt 7 has its discharge direction switched by a paper discharge flapper 30, and when a flapper 5L31 that moves it is turned on, the document is discharged to a discharge tray 32 provided on the left side of the DF, and is sequentially loaded. When the flapper 5L31 is off, the paper ejection rollers 15. are reversed and pressed against each other. 16, and are sequentially stacked on the digitizer cover described above.

FIG. 2-1 is a schematic diagram of the digitizer section of the present invention.

This is composed of one each of planar resistors 50 for reading positions in the horizontal direction (X direction) and the vertical direction (Y direction), and a lead pen switch (SW) 51.

The planar resistor 50 is placed not only under the sheet where the original is placed, but also under the clear key 52. Registration key 53. It is also located under keys such as the continuous designation key 54, and as described later, the pen switch
Voltage is output according to the position set by , and read as the area setting value or the above key.

The operator places the document face up on the resistor 50 and sets it so that it is aligned with the upper right corner. Then, two points in the area specified with the pen 5W51, for example, A, A'□ point or B.

By pressing point B', the area A-B'-A'-B'-A is specified, and by pressing the registration key 53 (described later) with the pen SW, the area specification is set.For example, the trimming function or the The image conversion function works and a copy as shown in Figure 2-2 is output.

FIG. 3 is a block diagram showing the control section of the DF and copying machine. The controller in the figure is a well-known microcomputer (
The microcomputer (hereinafter referred to as a microcomputer) accesses the RAM 110 by a program stored in an internal ROM.

Output signals to the DF section are sent via the driver to each of the loads mentioned above, namely the forward rotation and reverse rotation signals of the drive motor, the DF input lost collar SL, the digitizer entrance stop collar SL, and the discharge flapper S.
0N10FF L. Input signals include the aforementioned sensors, ie, DF occupancy sensor, DFh output sensor, digitizer occupancy sensor, digitizer opening/closing sensor, and clock pulse signals, which are input via a buffer. In addition, the output signal from the digitizer section is an X/Y application switching signal that switches the voltage applied to the digitizer electrode, with X-axis application at °L' and Y-axis application at °H''.The input signal is the digitizer electrode surface of the lead pen. A lead pen signal that turns on when pressed,
The analog signal output depending on the pressed position is
There are an X-axis input voltage signal and a Y-axis input voltage signal that are respectively input in the Y-axis direction. Furthermore, it is configured to output input/output signals to each control section of the copying machine.

FIG. 4 is a detailed flow chart of the digitizer settings 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 to be turned on to detect the press of the lead pen (step).

When the ON signal is input, the voltage applied to the electrode is immediately changed to
Specify the axis, convert the voltage generated depending on the pressed position, that is, the X-axis input voltage, and convert it to (X-BuF) in the RAM.
(step 102). Next, the applied voltage is switched to Y-axis designation, and the input voltage is similarly stored in (Y-BuF) (step 103). Then, the data of (Y-BuF) is compared with the value of MAX within a predetermined area, and it is determined whether it is within or outside the area (s'tep 104). If it is within the area, the area specification data address in RAM (
X-2nd) (Y-2nd) (X-1st) (Y-
1st) and shifted the contents of the data imported this time (X-
BuF) (Y-BuF) (X-1st) (Y-1s
t), the coordinates of the specified area are refreshed and data of two points are always stored.

This way, even if the coordinates are specified sequentially, the latest data will always be available. Then, in step 104 described above, if the key is outside the area, a search is made to see if it is a mode setting key.

In 5tep 106, it is checked whether the data of (X-BuF) at that time is a predetermined clear key voltage value, and flags up to the registration flag to be described later are directly cleared. Also, in 5tep 107, (Y-BuF) is compared with the registered key voltage value, and if they are equal, a registration flag is set. Digitizer area designation is completed by pressing this registration key, and this registration flag allows the copying machine to Determine whether digitizer area specification is set when copying starts.

Furthermore, in 5tep 108, the data of (X-BuF) is compared with the continuous specified 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 of the present invention. In particular, the * mark first detects the opening/closing of the DF digitizer cover in the flow described later, and then determines whether it is in digitizer mode or DF mode (step
p201) In the open state, it becomes dentizer mode, and 5te
Proceed to p202. At this point, the digitizer setting is accepted for the first time, and the process waits while processing the digitizer setting sub described above until a registration flag is set to determine completion of the setting. Then, by checking whether a document is set on the digitizer population sensor only after the settings are completed, the document feeding operation is prohibited unless the digitizer settings are performed (step 203).
.

On the other hand, when the digitizer cover is closed at step 5201, the normal DF mode is entered, and the process proceeds to step 5204, where the registration flag described above and the continuity flag described below are cleared.

This provides a clear function that cancels the digitizer settings when the cover is closed, which is equivalent to pressing the clear key described above. Then, in step 205, a document feeding operation is started by checking whether a document is set on the DF human sensor. In other words, the determination in step 201 is such that the original paper feed port is selected with the digitizer cover open, only the digitizer paper feed port is selected, and the cover is closed, and only the DF paper feed port is selected. With these functions, if a user wants to use a digitizer, for example, the user can smoothly perform the operations of opening the cover, setting the digitizer, and feeding paper.

Then, paper feeding in each mode is started, and in the digitizer mode, the digitizer paper feeding process and registration process are performed in 5 steps 206, and the paper is stopped at a predetermined position on the platen glass from the digitizer opening, while in the DF mode, the paper is stopped in a predetermined position on the platen glass in 5 steps 211.
F Paper feed processing and registration processing are performed, and the paper is stopped on the platen glass from the DF opening.

After this stop, the copy operation begins, and of course in the digitizer mode, the area specified copy operation is performed (step
208) Perform normal copy operation in DF mode (ste
p212). Especially in the digitizer mode, the registration flag is cleared once (step 207) and then the area specified copy operation is started.
Since feeding of the next document is permitted after waiting for the registration flag to be set in ep202, in other words, the normal usage is to set the digitizer once for one document, and the user can then set the digitizer once for each document. By not allowing paper to be fed even if the setting is incorrect, it is effective in preventing mistakes. Then, in step 5208, while waiting for the end of the copy operation, in step 209, the digitizer setting SuB for the next document is processed until the registration flag is set, and setting of area designation is permitted. This means that the next area specification is allowed during copying, and the functionality has been greatly improved from the previous one, where area specification could only be accepted in standby mode. This will lead to an increase in the total efficiency of area-specific copying.

Furthermore, if the continuous flag is set by the continuous designation key, the area designation that has been set will continue to be performed for consecutive documents. That is, in 5tep 207, if there is a continuous flag, the registration flag is not blown, and therefore, in 5tep 209, new digitizer setting during copying is prohibited, and in 5tep 202, digitizer setting during standby is also prohibited, so the above-mentioned operation is performed. To clear the continuous flag, close the digitizer cover (step 204) or press the clear key (step 10).
6).

[Effects] As described above, according to the present invention, an arbitrary area on a document can be specified, the document can be fed, and copies can be made without causing unnecessary trouble to the operator with a simple configuration and without causing any malfunction. becomes possible.
