Further, the image input unit 20 forms a reflected light image from a document placed at a predetermined reading position on the image sensor, and converts RGB (R: Red, G: Green, B: Blue) analog data. Output.

  For example, the image processing unit 30 generates digital image data based on analog data input from the image input unit 20, or reads out image data stored in the storage unit 70, and outputs After performing the corresponding processing, image data to be output (printed) is generated. The output image data generated by the image processing unit 30 is output to the image output unit 40.

  The image output unit 40 prints an image based on the image data output from the image processing unit 30 on a recording medium such as a recording sheet or an OHP film. The image output unit 40 generates a latent image on the photosensitive drum by emitting a laser beam in accordance with a photosensitive drum, a charger for charging the photosensitive drum to a predetermined potential, and image data received from the outside. A laser writing device, a developing device that supplies toner to an electrostatic latent image formed on the surface of the photosensitive drum to develop the electrostatic latent image, a transfer device that transfers a toner image formed on the surface of the photosensitive drum onto a recording medium, and the like. For example, an image is output on a recording medium by an electrophotographic method.

  The transmission / reception unit 50 includes a network card, a modem, and the like for transmitting the document data to the outside.

  The operation panel 60 is a function button for switching functions such as “fax”, “copy”, “print”, and “mail” in the multifunction peripheral 100, a ten-key, a start key, a cancel key, and a button for confirming a received instruction. It has an enter key and the like. The operation panel 60 has a touch panel 61, a pressure sensor 62 (detection means), and a display 63.

  The touch panel unit 61 has a touch panel (not shown), and the touch panel (contact surface) is provided so as to cover the display screen of the display unit 63. For example, the touch panel 61 is of a multi-touch resistive type. In the multi-touch resistive touch panel, a spacer (5 to 10 μm) is sandwiched on a base glass surface, and a film (a PET sheet having a thickness of about 200 μm) is attached to the surface thereof. On the mutually facing surfaces, a transparent electrode grid of ITO is provided. The resistive touch panel is configured to detect a touched position by measuring a voltage division ratio by a resistance of the transparent electrode on each of the glass surface and the film surface.

  Therefore, the touch panel unit 61 can receive designation of a predetermined position on the display screen of the display unit 63 by a user's touch operation on the touch panel. The touch panel unit 61 detects coordinates on the display screen of the display unit 63 corresponding to the position of the contact, and generates a signal for specifying the coordinates. Further, the touch panel unit 61 is not limited to this, and may be configured to use a pointing device (for example, a stylus pen) or the like.

  The display unit 63 includes, for example, an LCD or an EL (Electroluminescence) panel, and displays an image to be output (printed) on a predetermined recording sheet via the image output unit 40. The display unit 63 displays information to be notified to the user, such as the state of the multifunction peripheral 100, the status of job processing, the image of the document read by the image input unit 20, and the operation details of the operation panel 60. I do. The display screen of the display unit 63 is covered with the touch panel unit 61.

  The pressure sensor unit 62 is interposed between the touch panel unit 61 and the display unit 63. The pressure sensor unit 62 detects the pressure applied to the touch panel unit 61. The pressure sensor 62 can detect the pressure applied to the touch panel 61 (touch panel) in the entire range of the touch panel. The pressure sensor unit 62 detects the pressure applied to the touch panel, and outputs a pressure value corresponding to the magnitude of the pressure as an electric signal. The electric signal output from the pressure sensor unit 62 is sent to the control unit 10. For example, a known piezoresistive sensor is used for the pressure sensor unit 62.

  The storage unit 70 is configured by a nonvolatile storage medium such as a flash memory, an EEPROM (registered trademark), an HDD, an MRAM (a magnetoresistive memory), an FeRAM (a ferroelectric memory), or an OUM.

  FIG. 2 is a functional block diagram illustrating a main configuration of the control unit 10 in the multifunction peripheral 100 according to the first embodiment of the present invention. The control unit 10 includes a CPU 11, a ROM 12, a RAM 13, a display control unit 14, a direction determination unit 15, and a speed determination unit 16.

  The ROM 12 stores in advance various control programs and basically fixed data and the like among the parameters for calculation, and the RAM 13 temporarily stores the data and reads out the data regardless of the storage order and the storage position. Is possible. Further, the RAM 13 stores, for example, a program read from the ROM 12, various data generated by executing the program, parameters which are appropriately changed at the time of the execution, and the like.

  The CPU 11 controls the above-described various hardware by loading a control program stored in the ROM 12 in advance on the RAM 13 and executing the control program, and causes the entire apparatus to operate as the multifunction peripheral 100 of the present invention. Further, the CPU 11 receives an instruction of a predetermined process from the user via the touch panel unit 61.

  The display control unit 14 controls image display on the display unit 63. For example, the image displayed on the display unit 63 is scroll-displayed in the direction determined by the direction determining unit 15 at the speed determined by the speed determining unit 16.

  The direction determining unit 15 determines a direction related to scroll display of an image displayed on the display unit 63. More specifically, when the touch panel 61 receives designation of a plurality of positions by a user's touch operation, the direction determination unit 15 determines the direction of the scroll display based on the positions related to the designation of the plurality of positions.

  For example, in the case of a so-called drag operation in which the position of the contact is changed while the user's fingertip is in contact with the touch panel, the pressure sensor unit 62 performs the detection a plurality of times during the drag. More specifically, during such a drag, the pressure sensor unit 62 performs detection at a detection timing of a regular or irregular interval, and the direction determination unit 15 determines a direction based on a position related to any two timings. I do. That is, the direction determining unit 15 determines a direction connecting a position related to any two timings in a straight line as the scroll display direction.

  When the user's fingertip contacts the touch panel a plurality of times at predetermined intervals, the direction is determined based on the position of any two of the plurality of contacts. For example, a direction connecting a position related to the first contact and a position related to any of the second and subsequent contacts in a straight line is determined as the direction of the scroll display.

  The speed determining unit 16 determines the speed of the scroll display based on the detection result of the pressure sensor unit 62. That is, the speed determining unit 16 increases or decreases the speed of the scroll display according to the magnitude of the pressure value detected by the pressure sensor unit 62. For example, the speed determination unit 16 determines the corresponding speed by comparing the pressure value detected by the pressure sensor unit 62 with the threshold value table of the pressure value.

  In the multifunction peripheral 100 having the above-described configuration according to the first embodiment of the present invention, the direction and speed of the scroll display of the image on the display unit 63 can be easily adjusted according to the touch operation of the user. .

  FIG. 3 is a flowchart illustrating a process of adjusting the direction and speed of the scroll display in the multifunction peripheral 100 according to the first embodiment of the present invention. For convenience of explanation, a case where the user performs a so-called drag operation to scroll and display an image displayed on the display unit 63 will be described as an example. During the drag, the pressure sensor unit 62 performs detection at regular detection timing, and the direction determination unit 15 determines the direction of the scroll display based on the position related to the first contact and the position related to the first timing. Shall be determined. The RAM 13 stores the timing at which the pressure sensor 62 detects the pressure.

  For example, when the user touches the display screen (touch panel) of the display unit 63 with a fingertip, the touch panel unit 61 detects the touched position and sends a signal specifying the coordinates of the position to the CPU 11.

  The CPU 11 determines whether there is a touch (touch) on the touch panel based on a signal from the touch panel unit 61 (step S101). When the CPU 11 determines that the touch panel has not been touched (step S101: NO), the CPU 11 repeats the determination.

  When determining that there is a touch on the touch panel (step S101: YES), the CPU 11 detects a position (coordinate) on the display screen of the display unit 63 related to the touch based on a signal from the touch panel unit 61. (Step S102).

  At this time, the CPU 11 substitutes 1 for “N” and stores it in the RAM 13 (step S103).

  The CPU 11 determines whether or not it is time to detect the pressure by the pressure sensor 62 based on the timing result of the timing unit (not shown) and the detection timing of the RAM 13 (step S104).

  If the CPU 11 determines that it is not time to detect the pressure by the pressure sensor unit 62 (step S104: NO), it repeatedly performs such determination.

  On the other hand, if the CPU 11 determines that it is time to detect the pressure by the pressure sensor unit 62 (step S104: YES), the CPU 11 substitutes “N + 1” as “N” and stores it in the RAM 13 (step S105). ). That is, “2” is stored in the RAM 13 as the value of “N”. In other words, the contact in the first step S101 is treated as the first detection timing in the subsequent processing.

  Next, the CPU 11 determines whether “N” is “2” by referring to the storage content of the RAM 13 (step S106). If the CPU 11 determines that “N” is not “2” (step S106: NO), that is, if it is the third or subsequent detection timing, the process proceeds to step S108.

  On the other hand, since it is the timing of the second detection, “N” is “2”, and the CPU 11 determines that “N” is “2” (step S106: YES). At this time, the direction determining unit 15 determines the direction related to the scroll display of the image based on the contact positions detected at the first and second detection timings (step S107). In other words, during the dragging, the direction determining unit 15 determines the direction connecting the positions related to the first and second detection timings in a straight line as the scroll display direction.

  Next, the pressure sensor unit 62 detects a pressure value applied to the touch panel by the contact at the timing of the second detection (Step S108). Further, the speed determining unit 16 compares the pressure value detected by the pressure sensor unit 62 with the threshold value table of the pressure value, and determines a corresponding speed as the speed of the scroll display of the image (step S109).

  Further, the display control unit 14 scrolls the image displayed on the display unit 63 in the direction determined by the direction determination unit 15 at the speed determined by the speed determination unit 16 (step S110).

  Next, the CPU 11 determines whether contact with the touch panel has been released based on a signal from the touch panel unit 61 (step S111).

  When determining that the touch on the touch panel has not been released (step S111: NO), that is, when the drag operation is continuously performed, the CPU 11 returns the process to step S104.

  Thereafter, the processing from step S108 to step S110 is repeatedly performed until the user's drag operation ends. In other words, as shown in FIG. 4, during the drag operation of the user, the speed at which the image displayed on the display unit 63 is scrolled is sequentially changed according to the change in the pressure at which the fingertip presses the touch panel. .

  On the other hand, if the CPU 11 determines that the touch on the touch panel has been released (step S111: YES), the process ends.

  As described above, in the multifunction peripheral 100 according to the first embodiment of the present invention, the direction and speed in the scroll display of such an image are determined only by the operation of the user pressing the fingertip on the touch panel, so that the operability is improved. be able to. Further, the user can change the speed of the scroll display of the image each time only by appropriately adjusting the degree of the pressing (pressure).

(Embodiment 2)
FIG. 5 is a flowchart illustrating a process of adjusting the direction and speed of scroll display in the multifunction peripheral 100 according to the second embodiment of the present invention. For convenience of explanation, a case where the user performs a so-called drag operation to scroll and display the image displayed on the display unit 63 will be described as an example. During the drag, the pressure sensor unit 62 performs detection at regular detection timing, and the direction determination unit 15 determines the direction of the scroll display based on the position related to the first contact and the position related to the first timing. Shall be determined. The RAM 13 stores the timing at which the pressure sensor 62 detects the pressure.

  For example, when the user touches the display screen (touch panel) of the display unit 63 with a fingertip, the touch panel unit 61 detects the touched position and sends a signal specifying the coordinates of the position to the CPU 11.

  The CPU 11 determines whether or not the touch panel has been touched based on a signal from the touch panel unit 61 (step S201). When it is determined that the touch panel has not been touched (step S201: NO), the CPU 11 repeats such determination.

  When determining that there is a touch on the touch panel (step S201: YES), the CPU 11 detects a position (coordinate) on the display screen of the display unit 63 related to the touch based on a signal from the touch panel unit 61. (Step S202).

  At this time, the pressure sensor unit 62 detects a pressure value applied to the touch panel by the contact and stores the pressure value in the RAM 13 (step S203).

  Thereafter, the processing from step S204 to step S209 is the same as the processing from step S103 to step S108 in FIG. 3, and a detailed description will be omitted.

  In step S208, when the pressure sensor unit 62 detects the pressure value applied to the touch panel by the contact at the timing of the second detection, the speed determination unit 16 determines the pressure value detected by the pressure sensor unit 62 (hereinafter referred to as the pressure value). , The detected pressure value), a weight value is added to the speed according to the threshold value table for the pressure value, and the speed is determined as the scroll display speed of the image (step S210).

  That is, the speed determination unit 16 determines a predetermined weight value according to the detected pressure value, and adds the determined weight value to the speed according to the threshold value table of the pressure value corresponding to the detected pressure value, The speed of scroll display of the image is determined.

  Thereafter, the processing in steps S211 and S212 is the same as the processing in steps S110 and S111 in FIG. 3, and a detailed description is omitted.

  As described above, in the multifunction peripheral 100 according to the second embodiment of the present invention, at the time of the drag operation by the user, depending on the pressure value at the time of the first touch (contact), the speed of the subsequent scroll display of the image is changed. Add weight to decision.

  FIG. 6 is a graph showing the relationship between the detected pressure and the scroll display of an image in the multifunction peripheral 100 according to the second embodiment of the present invention. In FIG. 6, the drag operation indicated by the thick solid line, the dotted line, and the solid line has different initial pressure values, but subsequent pressure values are the same.

  That is, in the multifunction peripheral 100 according to the second embodiment of the present invention, the speed of the scroll display of the image is different depending on the pressure value at the time of the first contact even if the subsequent detected pressure values are the same.

  Thus, in the multifunction peripheral 100 according to the second embodiment of the present invention, it is possible to more quickly reach the scroll display speed of the image desired by the user.

(Embodiment 3)
In the above description, the case where the user performs a drag operation has been described as an example, but the MFP 100 according to the present invention is not limited to this, and the user performs a plurality of touches (contacts) at predetermined intervals. It is configured to be able to cope with such cases.

  FIG. 7 is a flowchart illustrating a process of adjusting the direction and speed of scroll display in the multifunction peripheral 100 according to the third embodiment of the present invention. For convenience of description, a case where the user performs a drag operation together with a second touch operation at a predetermined time interval after the first touch operation will be described as an example. The direction determining unit 15 determines the direction of the scroll display based on the positions of the first and second touch operations.

  Further, the multifunction peripheral 100 according to the third embodiment of the present invention includes a counting unit (not shown) for counting the number of touches (contacts) by the user. For example, when the user touches the display screen (touch panel) of the display unit 63 with a fingertip, the touch panel unit 61 detects the touched position, sends a signal specifying the coordinates of the position to the CPU 11, and sends the signal to the counting unit. Counts the number of contacts.

  The CPU 11 determines whether or not there has been contact with the touch panel based on a signal from the touch panel unit 61 (step S301). When it is determined that the touch panel has not been touched (step S301: NO), the CPU 11 repeatedly performs such determination.

  When determining that there is a touch on the touch panel (step S301: YES), the CPU 11 determines whether the touch is the first touch based on the count result of the counting unit (step S301). S302).

  When determining that the contact is the first contact (step S302: YES), the CPU 11 detects a position (coordinate) on the display screen of the display unit 63 related to the contact based on a signal from the touch panel unit 61. (Step S309). Thereafter, the process returns to step S301.

  When the CPU 11 determines that the contact is not the first contact (step S302: NO), that is, in the present embodiment, when the contact is the second contact, the direction determining unit 15 performs the first and second contacts. The direction related to the scroll display of the image is determined based on the position of the contact (step S303). That is, the direction determining unit 15 determines the direction connecting the positions related to the first and second contacts in a straight line as the direction of the scroll display.

  Next, the pressure sensor unit 62 detects a pressure value applied to the touch panel by the first contact (step S304). Further, the speed determining unit 16 compares the pressure value detected by the pressure sensor unit 62 with the threshold value table of the pressure value, and determines a corresponding speed as the speed of the scroll display of the image (step S305).

  At this time, the display control unit 14 scrolls and displays the image displayed on the display unit 63 in the direction determined by the direction determination unit 15 at the speed determined by the speed determination unit 16 (step S306).

  As described above, in the present embodiment, the user performs the drag operation at the time of the second touch (contact), and thus the CPU 11 determines whether or not it is time to detect the pressure by the pressure sensor unit 62. (Step S307). On the other hand, the timing at which the pressure is detected by the pressure sensor unit 62 is stored in the RAM 13.

  When determining that it is time to perform pressure detection by the pressure sensor unit 62 (step S307: YES), the CPU 11 returns the process to step S304.

  On the other hand, if the CPU 11 determines that it is not the time to detect the pressure by the pressure sensor unit 62 (step S307: NO), it determines based on the signal from the touch panel unit 61 whether the touch on the touch panel has been released (step S307). Step S308).

  If the CPU 11 determines that the touch on the touch panel has not been released (step S308: NO), that is, if the drag operation is continuously performed, the process returns to step S307.

  Thereafter, the processing from step S304 to step S306 is repeatedly performed until the user's drag operation ends. Therefore, as shown in FIG. 8, during the drag operation of the user, the speed at which the image displayed on the display unit 63 is scrolled is sequentially changed according to the change in the pressure at which the fingertip presses the touch panel.

  On the other hand, when determining that the touch on the touch panel has been released (step S308: YES), the CPU 11 ends the process.

  As described above, the multifunction peripheral 100 according to the third embodiment of the present invention can cope with a case where the user performs a plurality of touches (contacts) at predetermined intervals.

The multifunction peripheral 100 according to the fourth embodiment of the present invention is also configured to cope with a case where a user performs a plurality of touches (contacts) at predetermined intervals.

FIG. 9 is a flowchart illustrating a process for adjusting the scroll display direction and speed in the multifunction peripheral 100 according to the fourth embodiment of the present invention. For convenience of explanation, a case where the user performs a touch operation a plurality of times at predetermined time intervals will be described as an example. The direction determining unit 15 determines the direction of the scroll display based on the positions of the first and second touch operations. Further, the multifunction peripheral 100 according to the fourth embodiment of the present invention includes the counting unit (not shown) and a time measuring unit (not shown) that measures the time elapsed from the start of the contact.

  For example, when the user touches the display screen (touch panel) of the display unit 63 with a fingertip, the touch panel unit 61 detects the touched position and sends a signal specifying the coordinates of the position to the CPU 11. Further, the counting section counts the number of times of contact, and the timing section starts timing.

  The CPU 11 determines whether there has been a touch (touch) on the touch panel based on a signal from the touch panel unit 61 (step S401). When the CPU 11 determines that the touch panel has not been touched (step S401: NO), the CPU 11 repeats the determination.

  When determining that the touch panel has been touched (step S401: YES), the CPU 11 determines whether or not the operation related to the touch has continued for a predetermined time or more based on the result of the clocking of the clocking unit. . That is, the CPU 11 determines whether or not the operation related to the contact is a long press (step S402).

  If the CPU 11 determines that the operation related to the contact is a long press (step S402: YES), the process ends.

  On the other hand, when the CPU 11 determines that the operation related to the contact is not a long press (step S402: NO), the CPU 11 determines whether the contact is the first contact based on the count result of the counting unit ( Step S403).

  When determining that the contact is the first contact (step S403: YES), the CPU 11 detects a position (coordinate) on the display screen of the display unit 63 related to the contact based on a signal from the touch panel unit 61. (Step S410).

  At this time, the pressure sensor unit 62 detects a pressure value applied to the touch panel by the contact and stores the pressure value in the RAM 13 (Step S411). Thereafter, the process returns to step S401.

  On the other hand, if the CPU 11 determines that the contact is not the first contact (step S403: NO), the CPU 11 determines again whether it is the third or more contact based on the count result of the counting unit (step S403). S404).

  If the CPU 11 determines that the contact is the third or more contact (step S404: YES), the CPU 11 shifts the processing to step S406.

  If the CPU 11 determines that the contact is not the third or more contact (step S404: NO), that is, if it is the second contact, the direction determining unit 15 sets the position of the first and second contacts. Then, the direction related to the scroll display of the image is determined (step S405).

  Next, the pressure sensor unit 62 detects a pressure value applied to the touch panel by the second or third or more contact (step S406). Further, the speed determination unit 16 determines a scroll display speed of the image by adding a weight value to the speed according to the threshold value table of the pressure value corresponding to the detected pressure value detected by the pressure sensor unit 62 (step S407).

  That is, the speed determining unit 16 determines a predetermined weight value according to the detected pressure value related to the first contact, and determines the determined weight value according to the speed according to the threshold value table of the pressure value corresponding to the detected pressure value. To determine the speed of the scroll display of the image.

  At this time, the display control unit 14 scrolls and displays the image displayed on the display unit 63 in the direction determined by the direction determining unit 15 at the speed determined by the speed determining unit 16 (step S408).

  Next, the CPU 11 determines whether contact with the touch panel has been released based on a signal from the touch panel unit 61 (step S409).

  When determining that the touch on the touch panel has not been released (step S409: NO), the CPU 11 returns the process to step S408.

  On the other hand, if the CPU 11 determines that the contact with the touch panel has been released (step S409: YES), the process returns to step S401.

  As described above, in the multifunction peripheral 100 according to the fourth embodiment of the present invention, when the user performs a plurality of touches (contacts) at predetermined intervals, the fingertip presses the touch panel each time the touch is performed. As shown in FIG. 10, the speed at which the images displayed on the display unit 63 are scrolled and displayed is changed according to the change in the pressure.

  Further, in the multifunction peripheral 100 according to the fourth embodiment of the present invention, a weight value is added to the determination of the speed in the scroll display of the subsequent image according to the pressure value at the time of the first touch (contact). Therefore, as shown in FIG. 10, the speed of the scroll display of the image is different depending on the pressure value at the time of the first contact, even if the detected pressure value for the subsequent touch operation is the same.

  Thus, in the multifunction peripheral 100 according to the fourth embodiment of the present invention, it is possible to more quickly reach the scroll display speed of the image desired by the user.

  Therefore, in the multifunction peripheral 100 according to the fifth embodiment of the present invention, the speed determining unit 16 compares the pressure value detected by the pressure sensor unit 62 with the threshold value table of the pressure value, and includes the detected pressure value. The speed associated with the pressure value range to be displayed is determined as the speed of the scroll display of the image.

  Thus, in the multifunction peripheral 100 according to the fifth embodiment of the present invention, the scroll display speed can be stably adjusted.

  That is, when the user presses the touch panel with a fingertip, the pressure applied to the touch panel is not constant but slightly changes. Therefore, if the speed of the scroll display is sequentially changed according to such a subtle change, it is difficult to perform the scroll display at a stable speed.

  However, in the multifunction peripheral 100 according to the fifth embodiment of the present invention, in the pressure value threshold table, the speed is associated with each pressure value range.
