As a point, a first paper transport path 113 and a second paper transport path 114 are formed. Specifically, the former conveying path 113 extends from the position of the roller pair 14 obliquely upward to the left in the drawing and is formed up to the discharge roller pair 142. On the other hand, the latter conveyance path 114 extends to the lower right and conversely, and is formed up to the intermediate tray 15.

  Further, four paper carry-in mechanisms 151 are arranged in the second paper transport path 114, and the paper P is guided onto the paper tray 152 of the intermediate tray 15 via different paths for each size. The cradle 152 is disposed between the pressing roller 153 and the endless belt 155, and the belt 155 is located near the upper end of the conveyance path 114, that is, a driving pulley 154 a installed at the uppermost position of the cradle 152. And a driven pulley 154b installed at the lowest position of the cradle 152. Further, the belt 155 is provided with a receiving member 154.

The cradle 152 is set to a capacity capable of holding a plurality of sheets (for example, about 20 plain paper sheets), and the stapler 16 performs a stapling process on the sheet bundle P1 formed by the cradle 152. Has been given.
This stapling process is performed in a state where the discharge mode of the post-processing device 4 is set to the stapling mode, and the stapler 16 binds the sheet bundle P1 temporarily stored in the receiving tray 152.

The discharge device 20 is provided on the side surface of the housing 11 opposite to the paper inlet 111.
Specifically, the apparatus 20 has two trays arranged in two upper and lower stages. In this embodiment, the main tray 30 is arranged on the lower side, and the sub-tray 40 is arranged on the upper side. Each of these trays 30 and 40 is inclined and extended so as to rise obliquely upward and leftward from the housing 11 in FIG. An alignment member 50 is provided between the trays 30 and 40 to align the leading ends of the sheet bundle P1.

The belt 155 conveys the sheet bundle P1 subjected to the stapling process by driving upward, and the discharge roller pair 156 sequentially discharges the sheet bundle P1 onto the main tray 30. On the other hand, the discharge roller pair 142 described above discharges the paper P, which is not subjected to stapling processing, to the sub-tray 40 one by one.

  By the way, whether or not to execute the above-described double-sided printing, punching processing, stapling processing, or the like is determined by the user touching the operation button on the operation / display unit 110. The processing determined by the operation / display unit 110 is controlled by the image formation control unit 120, and the set data is stored in the storage unit 130.

  Specifically, as shown in FIG. 3, the operation / display unit 110 of the present embodiment includes a liquid crystal display (LCD) 110a as a screen display unit, a touch panel (touch input unit) 110b, a touch control unit 110c, and An LCD control unit 110d is provided. The display 110a is provided on the outer cover surface of the image forming apparatus 2 at a position that is easily visible to the user, and is driven by the LCD control unit 110d.

The display 110a displays operation information to be performed by the user, for example, paper size, enlargement / reduction, double-sided printing, punch punching, stapling, sorting, and the like in the form of operation buttons using characters and pictograms. The operation information is displayed as an effective area of the touch operation.
The touch panel 110b is provided at a position covering the display screen of the display 110a, and is configured to accept a user's touch operation. In addition, two-dimensional coordinates (XY coordinates) are virtually arranged on the surface of the panel 110b.

When the user touches a predetermined effective area of the display 110a via the panel 110b (touch operation), the touch position is detected by the touch control unit 110c, and processing according to the position can be executed.
Specifically, the control unit 110c includes a touch position detection unit (touch position detection unit) 110e, a touch count storage unit (touch count storage unit) 110f, and a touch processing execution unit 110g. The touch position detection unit 110e includes: A detection operation according to a detection method (for example, an ultrasonic method, an infrared method, a contact method, etc.) of the panel 110b is performed, and the coordinates of the touch position with respect to the effective area are detected and output to the touch frequency storage unit 110f.

The number storage unit 110f measures the number of touch operations at this coordinate. Specifically, the counter is incremented when the user touches a predetermined effective area, and then the counter is cleared when the user leaves the effective area. It outputs to the execution part 110g.
The process execution unit 110g analyzes a function corresponding to the touch operation based on the coordinates of the touch position and the determined operation, and executes a process based on the function.

Here, the processing execution unit 110g of the present embodiment has various functions for stabilizing the user's touch operation and preventing the user from getting tired.
Specifically, first, it has a function of letting the user know that the processing corresponding to the first touch position on the operation button is invalid (first invalidity informing means). In other words, this function does not let the user know the effective area, but makes the invalid area aware.

More specifically, in this embodiment, a “first-time process invalid” button described later is displayed on the display 110a, and the user does not execute a process corresponding to the first touch position after pressing the button. The fact is informed.
Then, a function that “does not respond to all areas of the screen” is registered for this button, and when the user touches the button via the touch panel 110b, the process execution unit 110g Processing that does not react to all areas of the display 110a is executed.

Next, it has a function of invalidating the process according to the first touch position with respect to the effective area (first-time process prohibiting means).
The function is specified based on the position and the number of times detected and stored by the position detection unit 110e and the number storage unit 110f, and is counted after the user touches the “Initial processing invalid” button. The touch position, that is, each operation button displayed on the display 110a, and all the processing in the effective area surrounding the button and causing some reaction are not executed.

  However, this function is canceled when the first touch operation is moved away from the position, that is, at the moment when the user's finger, the wrist, or the like moves away from the panel 110b. The touch panel 110b may be released at the moment when the operation button touched for the first time moves to another effective area while touching the panel 110b.

  And it has a function which performs the process according to the touch position after the 1st time with respect to an effective field (for example, the 2nd time) (process execution means). The function is also specified based on the position and the number of times detected and stored in the position detection unit 110e and the number storage unit 110f, and the second touch position is counted after the user touches the “Initial processing invalid” button. That is, the processing of each operation button displayed on the display 110a is executed.

Referring to FIGS. 4 and 5, flowcharts of the stabilization control of the touch operation executed by the operation / display unit 110 are shown, and the operation according to the present invention of the image forming apparatus configured as described above will be described below. To do.
First, in the present embodiment, a description will be given on the assumption that a document set on the tray 140 is copied on a sheet by reducing the vertical and horizontal directions at the same rate.

  First, if the current state of the image forming apparatus 2 is “standby”, the display 110a displays an initial screen having various operation buttons B1 to B6 in a predetermined layout (FIG. 6). In the display frames of these buttons B1 to B6, characters and pictograms are displayed in the order of “paper size”, “enlarge / reduce”, “double-sided printing”, “punching”, “staple stitching”, and “sort”. Is displayed.

  Among these, a function “set to the same ratio” is registered for the “enlarge / reduce” button B2, and when the user touches the button B2 via the touch panel 110b, the coordinates thereof are displayed by the position detection unit 110e. Detected and counted up for the button B2 in the number storage unit 110f. In response to this, the process execution unit 110g executes a process of simultaneously changing the magnification in the vertical direction and the horizontal direction on the display 110a, and switches the display content from the initial screen of FIG. 6 (FIG. 7).

  On the screen shown in FIG. 7, for example, a display frame C1 of “currently displayed numerical value” is displayed at the upper left, and a display frame C2 of “message” is displayed at the lower left, and these display frames C1 and C2 are displayed. In between, a “registration” button C3 and a “reset” button C4 are displayed along the vertical direction. Further, an “increase / decrease in numerical value by 1%” button C5 is displayed immediately on the right side of the “registration” button C3, and immediately to the right of the “reset” button C4 and below the “increase / decrease in numerical value by 1%” button C5. An “Numeric key input” button C6 is displayed. The right half of the display 110a is occupied by twelve buttons C7 of “Numeric keypad”, and the “Initial processing invalid” button C8 is displayed on the upper right.

  In step S401 in FIG. 4, it is determined whether or not the “initial process invalidation” button C8 has been pressed by the user, and if the pressing of the button C8 is detected by the position detection unit 110e and the number storage unit 110f (initial invalidation). If it is determined YES, that is, YES, the process proceeds to step S402, and the process execution unit 110g shifts to a mode in which the process corresponding to the first touch position is invalidated, and the image formation control unit 120 and the like. Output.

In the invalid mode in step S402, as shown in FIG. 5, in step S501, all areas of the display 110a are shifted to invalid areas.
Next, in step S502, the position detection unit 110e and the frequency storage unit 110f detect and store the first touch operation and proceed to step S503, and any processing according to the position of the first touch operation is invalidated. (First processing prohibition means).

  That is, as shown in FIG. 8, the middle finger (third finger) of this user has touched the left center part of the “ten-key” button C7, which is after touching the “Initial processing invalid” button C8. Since this is the first touch operation, the processing by this operation is invalidated, and the numerical value of this button C7 is not displayed in the display frame C1 of “currently displayed numerical value”.

  The invalid mode is continued until the position detection unit 110e performs the first touch operation, that is, until the middle finger of the user leaves the “tenkey” button C7. If the middle finger is separated from the button C7, That is, if YES is determined in step S504, the process proceeds to step S505, and the process execution unit 110g cancels the invalid mode. As a result, the series of invalid mode routines are exited, and the cancellation is output to the image forming control unit 120 and the like.

On the other hand, in the state shown in FIG. 8 described above, the middle finger of this user touches the “tenkey” button C7, and the index finger (second finger) touches the lower half of the “increase / decrease by 1%” button C5. In the case (step S403, FIG. 9), the vertical direction and the horizontal direction are reduced at the same rate.
More specifically, a function of “change the displayed numerical value in 1% increments” is registered for the “increase / decrease in numerical value 1%” button C5. In this case, the user's finger indicates the touch panel 110b. When the area of the button C5 is touched via the position, the coordinates are detected by the position detection unit 110e.

  At the same time, the count storage unit 110f counts after touching the “Initial process invalid” button C8 and measures that the touch operation is the second time, and the process execution unit 110g executes the process according to the touch position. (Processing execution means, step S404). Specifically, in the display frame C1 of “currently displayed numerical value”, a value that decreases from the numerical value by 1% is displayed in response to pressing of the button C5, and this index indicates the magnification desired by the user. When it is done, it is released from the panel 110b, and the above-described series of routines are exited.

If it is not detected in step S401 that the “Initial process invalidation” button C8 is pressed, the process immediately proceeds to step S403, and the process corresponding to the first touch position is executed.
Then, when the user presses the “Register” button C3, the numerical value of the display frame C1 is fixed and the screen is switched to the initial screen. These data are stored in the storage unit 103 via the image formation control unit 120.

By the way, the touch operation by the user described above may be performed with the user's thumb (first finger) and the index finger.
Specifically, in the touch operation shown in FIG. 10, the thumb is the first touch operation described above, and the processing according to the position is invalidated (first-time process prohibiting unit). Subsequently, the operation of drawing an arc with the index finger is the second touch operation, and processing corresponding to this position is executed (processing execution means).

  On the other hand, the touch operation by the user may be performed with the palm and the finger. In other words, in the user's palm, the wrist portion that is in the vicinity of the boundary with the wrist becomes the first touch operation and the processing corresponding to the position is invalidated (first-time processing prohibiting means), For example, the user's finger may be the second touch operation, and a process corresponding to this position may be executed (process execution means).

  As described above, in the image forming apparatus 2 according to the present exemplary embodiment, when various settings such as the magnification and the punching process are performed by the user's touch operation on the operation / display unit 110, the image forming process is performed by copying the document. . That is, when the user places a document on the tray 140 and presses a start button (not shown) of the operation / display unit 110, the document is sent one by one from the feeder 400 toward the scanner 144 and then discharged. .

  The scanner 144 scans an original image, and the read image data is stored in the storage unit 130 in units of one job via the control unit 120. The control unit 120 performs preprocessing such as image noise removal on the image data, performs image processing according to various settings, and outputs the data to the print engine 150 for each page. . As a result, an electrostatic latent image is formed on the surface of the photosensitive drum of the engine 150 and is developed with toner.

  On the other hand, the paper in the paper supply unit 160 is sent to the registration roller 170 and is waited by this roller 170. Next, at the timing when the photosensitive drum reaches a predetermined rotation angle, the sheet is conveyed from the roller 170 toward the engine 150, and the toner image is transferred. Subsequently, the sheet is heated and pressurized through the fixing device 180 to fix the toner image to become a transfer sheet. In the case of single-sided printing, the sheet passes between the discharge roller pair 191 to the post-processing device 4. Delivered.

  On the other hand, in the case of duplex printing, the sheet conveyance path on the downstream side of the fixing device 180 is switched downward in front of the discharge roller pair 191, and the sheet printed on one side is conveyed so as to sink underneath. . Next, the sheet conveyed downward is conveyed by the roller pair 182 in the opposite direction, that is, upward. Subsequently, the sheet is conveyed rightward in FIG. 1 below the fixing unit 180 and is sent toward the registration roller 170 via the roller pair 184. Then, the toner image is transferred to the surface where the toner image has not yet been transferred, and is transferred to the post-processing device 4 after fixing.

  2 delivered to the apparatus 4 is subjected to punching processing and stapling processing, and then discharged to the main tray 30 and the sub-tray 40. That is, the sheet P is guided by the guide plate 112 and conveyed to the punching machine 12. In this machine 12, when the leading end position of the paper P is brought into contact with a stopper (not shown) and the rod 121 penetrates the paper P, a punching hole is formed at a predetermined position of the paper P.

Subsequently, when the stopper of the machine 12 is retracted, the sheet P is sent to the curl removing device 13 by driving the roller pair 191 and then reaches the roller pair 14.
Here, when the branching claw 141 closes the conveyance path 114, the first sheet conveyance path 113 is opened, and the paper P delivered from the roller pair 14 is guided to the branching claw 141 and the conveyance path 113, and is discharged to the discharge roller. The paper is discharged to the sub-tray 40 through the pair 142.

  On the other hand, when the branching pawl 141 closes the transport path 113, the second paper transport path 114 is opened, and the paper P sent from the roller pair 14 is guided to the branch pawl 141 and the transport path 114, and the intermediate tray 15 It reaches the cradle 152 via The paper P on the cradle 152 is further moved downward by the rollers 153 and stopped by the receiving member 154.

Thereafter, the other paper P guided to the transport path 114 is positioned on the receiving member 154 with its transfer surface superimposed on the back surface of the previous paper P, for example, in the case of single-sided printing. When a plurality of sheets P are aligned on the receiving tray 152 and the sheet bundle P1 is formed, the stapler 16 performs the stapling process.
Next, when the drive pulley 154 a rotates, the sheet bundle P <b> 1 is conveyed upward and discharged to the main tray 30 via the discharge roller pair 156. After that, the other sheet bundle P1 subjected to the stapling process is discharged to the upper side of the previous sheet bundle P1 when the tray 30 is lowered.

  As described above, according to the present embodiment, the display 110a displays a plurality of operation buttons for executing processing according to the user's operation, and the position detection unit 110e accepts the buttons received by the touch panel 110b. The touch position is detected, and the number of touch operations is measured in the number storage unit 110f.

  And the process execution part 110g has made the user know that the process according to the 1st touch position becomes invalid (initial invalidity recognition means). Therefore, this user can perform the first touch operation without much compared with the case where the process according to the touch position is simply invalidated as in the prior art. In other words, as a result of being able to draw out the user's positive touch operation, the process desired by the user can be completed in a short period of time.

In addition, in the first touch operation by the user, the process according to the position is invalidated by the process execution unit 110g, and no process is apparently performed (first-time process prohibiting unit).
Then, the second touch operation can be performed using the first touch operation as a fulcrum, and the process according to the second touch position at which the fulcrum is obtained is executed by the process execution unit 110g (process Execution means). That is, the second touch position at which this fulcrum is obtained can be specified more quickly than in the case of conventional long press.

Further, even when the touch operation is repeated, the position is stabilized, so that mistouch can be reliably prevented. Moreover, according to the second touch operation that obtains this fulcrum, fatigue associated with the operation can be reduced.
Further, when the user leaves the first touch position, the process execution unit 110g cancels the invalidation of the process according to the first touch position. Accordingly, since it is not necessary to wait for a certain period of time until release as in the prior art, the subsequent touch operation can be performed quickly, which also contributes to the completion of processing in a short period.

Furthermore, if the user's middle finger is used as a fulcrum, and the touch operation is performed with the finger of the same hand that is close to this fulcrum and can be moved more dexterously than other fingers, an accurate touch can be achieved even if the touch operation to be aimed at is narrow. It can be done, and continuous touch operation becomes easy.
Further, if the user's wrist is used as a fulcrum and touch operation is performed with the index finger, the touch operation can be performed without lifting the hand holding the finger, so that the hand and the finger are hardly fatigued.

Furthermore, if the user's thumb is a fulcrum and the touch operation is performed with the same finger that can be moved most dexterously compared to the other fingers, for example, the finger can be placed on the panel 110b in an arc shape centered on the thumb. It becomes possible to deal with various operations such as tracing.
The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims.

  For example, in the above-described embodiment, the user is notified by pressing the “Initial processing invalid” button C8, but the present invention is not necessarily limited to this form. In other words, the display 110a may display a message indicating that the initial process is in the invalid mode, and notify the user. In this case, the process execution unit 110g shifts to the invalid mode immediately after switching from the initial screen, or You may make it transfer to invalid mode, when several seconds pass, touching the panel 110b.

The image forming apparatus 2 described above is an example of an electronic device, and the present invention can be employed in various electronic devices.
Specifically, as long as it is an electronic device that accepts operations using a touch panel, it accepts only operations such as a remote control in addition to a personal computer, automatic ticket vending machine, vending machine, or automatic teller machine (ATM). The present invention can also be applied to a device that sends an operation signal to cause the main body to execute an operation, and is particularly suitable for a touch-type panel that performs numerical value setting, time change, and the like. In these cases as well, it is possible to reliably prevent mistouch and to complete the processing desired by the user in a short period of time.

  In addition, the various members and driving parts mentioned in this embodiment are all preferable examples, and these can be appropriately modified and implemented.
