Description

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.

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, a new function has been added to image forming apparatuses such as copying machines that allows users to specify a certain area of a document and extract or extract only that specified area to form a copy11. ing. At that time, when specifying the area,
There are known methods in which the coordinates are manually determined, and methods in which the coordinates are determined 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 put it back on the platen glass.

Additionally, when the above-mentioned document handling device is installed in a copying machine, there is no need to install a digitizer device. For example, an external stand or the like is provided and the operator is required to replace the document each time. Moreover, there was a problem that the configuration was large-scale.

[Purpose] The present invention has been made in view of the above points, and its purpose is to provide a document handling system having a function of specifying an arbitrary area of a document with a simple configuration and improved operability. 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 stacked, and the sheet originals 2 on the entrance tray 1 are laid out with the lower side in the figure facing up. The first document detection DF human 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. A stopper 6 prevents the document from being fed onto the platen glass 10, and is released by the operation of the DF input lost flange solenoid 21 to enable feeding. 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 7 is an endless belt with a width that covers the entire surface of the sheet document.
It has a sufficient coefficient of friction so that it can be conveyed by sliding on the belt, and is wrapped around a drive roller 8 and a turn roller 9, and is configured to prevent the entire surface belt 7 and drive roller 8 from slipping. . Further, the ejection roller 11 is in pressure contact with the entire surface of the belt, and conveys the original ejected from the original glass 10 by sandwiching it, and when the DF output sensor 13 for detecting the original detects the leading edge of the original using a reflective sensor,
The entire belt is once stopped, then run in reverse, and when the DF output processor 13 detects the trailing edge of the document, it is stopped at a predetermined position.

Second, a well-known digitizer 26 is mounted on the top of the DF of the present invention, and a digitizer cover 27 that covers 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. Further, there is a digitizer paper feed port in the upper right corner of the DF that feeds the document on the digitizer, and although it is hidden when the cover is closed, it 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 is a stopper that prevents the document from being fed from the digitizer paper feed port onto the platen gas, and the digitizer inlet stopper solenoid 29
It is released by the operation of and enables feeding. The document sent out from the digitizer paper feed port by the conveyance rollers 23, 24 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, point A, point A', or point 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 0N10FF for each of the loads described above, namely the forward rotation and reverse rotation signals of the drive motor, the DF input lost collar SL, the digitizer section [1 stopper SL and the discharge flapper SL. The human power signals are inputted from the aforementioned sensors, ie, the DF human sensor, the DFh output sensor, the digitizer input sensor 2, the digitizer opening/closing sensor, and the clock pulse signal via a buffer. Additionally, the output signal from the digitizer section is an X/Y application switching signal that switches the voltage applied to the digitizer section pole.

Switching is performed by applying the X-axis at ゛H° and applying the Y-axis. As input signals, the lead pen signal that turns on when the lead pen is pressed against the digitizer electrode surface, and the X-axis input voltage signal and Y-axis input voltage signal that input analog signals output depending on the pressed position in the X/Y axis directions, respectively. be. Furthermore, it is configured to output input/output signals to each control section of the copying machine.

FIG. 4 is a detailed flowchart of the digitizer configuration 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 press of the lead pen is detected and the lead pen signal is turned on (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 terminal, 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 (step 104). If it is within the area, the area specification data address (X
-2nd) (Y-2nd) to (X-1st) (Y-1
Shift the contents of the data (,X-
BuF) (Y-BuF) (X-1st) (Y-1st
) to refresh the coordinates of the specified area and always store two points of data.

They will be all together. 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 5tep107, (Y-BuF) is compared with the registered key voltage value, and if they are equal, a registration flag is set.The digitizer area specification is completed by pressing this registration key, and this registration flag is used to set the registration flag. determines whether digitizer area specification is set when copying starts.

Furthermore, in step 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 mode in the flow described later, and thereby determines whether it is the digitizer mode or the DF mode (step
201) In the open state, it becomes dentizer mode, 5 steps
Proceed to 202. 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 or not 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 the above-mentioned clear key suppression. 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, he or she can smoothly perform the operations of opening the cover, setting the digitizer, and picking up paper.

Then, paper feeding in each mode is started, and in the digitizer mode, the digitizer paper feeding process and the registration process are performed in step 206, and the paper is stopped at a predetermined position on the platen glass from the digitizer opening, while in the DF mode, the DF paper feeding process and the registration process are performed in step 211. Perform resist processing and stop on the platen glass from the DF port.

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 is required to set the digitizer for the next document. If you forget the settings,
By not allowing paper to be fed, it is effective to prevent 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, which only accepted area specification in standby mode, and the total area specification copy. Leads to increased efficiency.

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 suppress the clear key (step 10).

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