<Image Forming Apparatus Provided with Operation Unit>
FIG. 1 is a conceptual diagram of an image forming apparatus including an operation unit according to an embodiment of the present invention. However, details of each part not directly related to the present invention are omitted.

  Note that the image forming apparatus including the operation unit of the present invention corresponds to, for example, a printer, a scanner alone, or a multifunction machine including a printer, a copy, a scanner, a fax, and the like, and includes a copy function, a scanner function, a facsimile function, and a printer. It functions as an image forming apparatus having functions and the like.

  The operation of the MFP 100 (MFP: Multi Function Peripheral) when using the copy function will be briefly described below.

  First, when the user uses the multifunction machine 100, the document is placed on the document table 101 provided on the upper surface of the casing. Subsequently, the user uses the operation unit 102 (operation panel) provided in the vicinity of the document table 101 to input setting conditions related to image formation from the operation screen of the operation unit 102. When the user presses a start key provided on the operation unit 102, the multifunction peripheral 100 starts image formation (print processing).

  Next, in the image reading unit 103, the light emitted from the light source 104 is reflected by the document placed on the document table 101. The reflected light is guided to the image sensor 108 by the mirrors 105, 106, and 107. The guided light is photoelectrically converted by the image sensor 108, and image data corresponding to the original is generated.

  An image forming unit 109 forms a toner image based on the image data. The image forming unit 109 is provided with a photosensitive drum 110. The photosensitive drum 110 rotates in a predetermined direction at a constant speed, and around the charger drum, the exposure unit 112, the developing unit 113, the transfer unit 114, the cleaning unit 115, and the like, in that order from the upstream side in the rotation direction. Is arranged.

  The charger 111 uniformly charges the surface of the photosensitive drum 110. The exposure unit 112 irradiates the charged surface of the photosensitive drum 110 with a laser based on the image data to form an electrostatic latent image. The developer 114 forms a toner image by attaching toner to the formed electrostatic latent image. The formed toner image is transferred to a recording medium (for example, paper, sheet) by the transfer device 114. The cleaning unit 115 removes excess toner left on the surface of the photosensitive drum 110. A series of these processes is executed by rotating the photosensitive drum 110.

  The paper is transported from a plurality of paper feed cassettes 116 provided in the multifunction peripheral 100. When transported, the paper is pulled out from any one of the paper feed cassettes 116 to the transport path by a pickup roller 117. Each sheet cassette 116 stores sheets of different paper types, and the sheets are fed based on setting conditions relating to image formation.

  The sheet pulled out to the conveyance path is sent between the photosensitive drum 110 and the transfer device 114 by the conveyance roller 118 and the registration roller 119. When the paper is fed, the toner image is transferred to the paper by the transfer device 114 and conveyed to the fixing device 120.

  When the paper on which the toner image has been transferred passes between a heating roller and a pressure roller provided in the fixing device 120, heat and pressure are applied to the toner image, and the visible image is fixed on the paper. The The amount of heat of the heating roller is optimally set according to the paper type, and the fixing is performed appropriately. The visible image is fixed on the paper and the image formation is completed, and the paper is guided to the path switching unit 121 by the transport roller 118.

  In the path switching unit 121, the sheet is guided to a sheet discharge tray 122 provided on a side surface of the casing unit or the casing through the sheet discharge port 123 according to a switching instruction from the multifunction peripheral 100. To the in-body tray 124 provided in the body cylinder. The sheets are stacked and stored on the paper discharge tray 122 or the in-body tray 124. Through the above procedure, the multifunction peripheral 100 provides a copy function to the user.

  Next, FIG. 2 is a conceptual diagram showing the overall configuration of the operation unit according to the embodiment of the present invention. The user uses the operation unit 102 to input setting conditions for image formation as described above, and to confirm the input setting conditions. When the setting conditions are input, a touch panel 201 (operation panel), a touch pen 202, and operation keys 203 provided in the operation unit 102 are used.

  The touch panel 201 has both a function for inputting setting conditions and a function for displaying the setting conditions. That is, by pressing a key in the screen displayed on the touch panel 201, a setting condition corresponding to the pressed key is input.

  A display unit such as an LCD (Liquid Crystal Display) is provided on the rear surface of the touch panel 201, and the display unit displays an operation screen such as the initial screen, for example. A touch pen 202 is provided in the vicinity of the touch panel 201. When the user brings the tip of the touch pen 202 into contact with the touch panel 201, a sensor provided under the touch panel 201 detects the touch destination.

  In addition, a piezoelectric element (not shown) is built in an end of the back surface of the touch panel 201, and the piezoelectric element is configured to vibrate appropriately in response to a user's touch on the touch panel 201 (described later).

  Further, a predetermined number of operation keys 203 are provided in the vicinity of the touch panel 201, and for example, a ten key 204, a start key 205, a clear key 206, a stop key 207, a reset key 208, and a power key 209 are provided.

  Next, the configuration of the control system hardware of the multifunction peripheral 100 will be described with reference to FIG. FIG. 3 is a diagram showing the configuration of the control system hardware of the multifunction peripheral 100 according to the present invention. However, details of each part not directly related to the present invention are omitted.

  The control circuit of the MFP 100 includes a CPU (Central Processing Unit) 301, a ROM (Read Only Memory) 302, a RAM (Random Access Memory) 303, a HDD (Hard Disk Drive) 304, a driver 305 corresponding to each driving unit, and an operation. The units 102 are connected by an internal bus 306.

  The CPU 301 uses, for example, the RAM 303 as a work area, executes a program stored in the ROM 302, the HDD 304, and the like, and based on the execution result, data and instructions from the driver 306 and the operation unit 102, keys, and the like 1 is transmitted and received, and the operation of each drive unit shown in FIG. 1 is controlled. Note that the control circuit of the operation unit 102 is also equivalent to the control circuit of the multi-function device 100, and thus the display and description thereof are omitted.

  Also, each means (shown in FIG. 4) to be described later other than the drive unit is realized by the CPU of the multifunction peripheral 100 and the operation unit 102 executing the program. The ROM, HDD, and the like store programs and data that realize each means described below.

<Embodiment of the present invention>
Next, the configuration and execution procedure according to the embodiment of the present invention will be described with reference to FIGS. 4 and 5. FIG. 4 is a functional block diagram of the multifunction machine according to the embodiment of the present invention. FIG. 5 is a flowchart for showing the execution procedure of the embodiment of the present invention.

  First, when the user turns on the power of the multifunction device 100, the multifunction device 100 is activated, and the display means 401 of the operation unit 102 of the multifunction device 100 displays an operation screen (initial screen) on the touch panel 201 (FIG. 5: S101).

  Here, when the user presses down (contacts or touches) a predetermined key displayed on the operation screen while looking at the operation screen, the detection unit 402 of the operation unit 102 detects the press of the key. (FIG. 5: S102 YES), the user's touch position is detected (FIG. 5: S103).

  Any method may be used for the detection unit 402 to detect the touch position of the user. For example, the detection unit 402 is configured as follows. That is, as shown in FIG. 6A, a predetermined corner (for example, the lower left corner) of the touch panel 201 is the origin, the right direction is the X direction, and the upper direction is the Y direction. A reference is set in advance. Next, when the detection unit 402 detects that the user has pressed the key, the touch position T of the user is compared with the reference, and the coordinate value TX in the X direction and the coordinate value TY in the Y direction of the touch position T are determined. Is calculated. Thereby, a user's touch position can be detected.

  When the detection unit 402 detects the touch position T of the user, the determination unit 403 notifies the determination unit 403, and the determination unit 403 that has received the notification notifies the piezoelectric element (vibrator) at a position close to the touch position of the user. The vibration parameters of each piezoelectric element are determined so that the vibration of the piezoelectric element located far from the touch position is weakened (FIG. 5: S104).

  Any method may be used as the method by which the determining unit 403 determines the vibration parameter of each piezoelectric element. For example, the method is as follows. That is, first, the determination unit 403 refers to a table stored in advance in a predetermined memory.

  Here, since the piezoelectric element provided on the touch panel 201 cannot normally vibrate the entire touch panel 201, the touch panel 201 is divided into a plurality of regions 600 as shown in FIG. The piezoelectric elements 601 are provided at predetermined positions in the divided areas.

  In the embodiment of the present invention, the touch panel 201 is divided into three regions 600 along the left-right direction (the left region is an A region 600a, the central region is a B region 600b, and the right region is a C region 600c), Two piezoelectric elements 601a and 601b are respectively provided at both ends of the predetermined region 600 in the vertical direction. The piezoelectric element 601 corresponding to one region 600 is connected to an IC (integrated circuit) 602 that controls the vibration, and this IC 602 is controlled by one master CPU 603.

  Corresponding to such a touch panel 201, as shown in FIG. 6B, the table 604 includes the divided area 605 and each area 600 when a touch position is detected in the area 605. Is stored in association with vibration information 606 indicating the strength of the vibration parameter. Here, any one of the A region 600a, the B region 600b, and the C region 600c is stored in the region 605, and the vibration information 606 includes vibration parameter strength, for example, when the vibration parameter is a frequency. Either a high frequency or a low frequency (a frequency smaller than the high frequency) is stored for each region 600. In the vibration information 606 corresponding to the area 605 (for example, the A area 600a) where the touch position is detected, information having a strong vibration parameter (for example, high frequency, several hundred Hz, etc.) is stored, and the touch position In the vibration information 606 corresponding to the region 605 other than the region 605 where the noise is detected (for example, the B and C regions 600b and 600c), information with weak vibration parameters (for example, low frequency, several tens of Hz, etc.) is stored. Yes. Accordingly, it is possible to increase the vibration parameter in a region close to this corresponding to the touch position of the user and weaken the vibration parameter in a region far from this.

  The determining unit 403 referring to the table 604 determines which of the divided areas 605 is included based on the coordinate value of the touch position of the user. In FIG. 6A, the determination unit 403 determines that the user's touch position T is included in the A area 600a. Then, the determination unit 403 determines vibration parameters of the piezoelectric element 601 for each area 600 with reference to the vibration information 606 of the table corresponding to the determined area. Here, a high frequency having a strong vibration parameter is determined for the piezoelectric elements 601a and 601b in the A region 600a, and a low frequency having a weak vibration parameter is determined for the piezoelectric elements 601a and 601b in the B and C regions 600b and 600c. The

  Then, when the determining unit 403 determines the vibration parameter, the vibration unit 404 is notified to that effect, and the vibration unit 404 that has received the notification vibrates each piezoelectric element 601 based on the determined vibration parameter (see FIG. 5: S105).

  Any method may be used as the method by which the vibration means 404 vibrates each piezoelectric element 601. For example, the method is as follows. That is, the vibration unit 404 transmits vibration parameters (high frequency, low frequency) for each IC 602 to the above-described master CPU 603, and the master CPU 603 vibrates the piezoelectric element 601 for each IC 602 based on the vibration parameters. Instruct them to do so. The IC 602 vibrates the piezoelectric element 601 based on the vibration parameter, but the IC 602 corresponding to the A region 600a vibrates the piezoelectric elements 601a and 601b at a high frequency as shown in FIG. The IC 602 corresponding to the regions 600b and 600c vibrates the piezoelectric elements 601a and 601b at a low frequency.

  Then, since the piezoelectric element 601 vibrates greatly in the vicinity of the user's touch position, the user can surely obtain a click feeling. On the other hand, since the piezoelectric element 601 vibrates slightly at a position far away from the touch position of the user, vibration cancellation due to vibration interference that has conventionally occurred is less likely to occur, and a click feeling is obtained regardless of where the user touches the touch panel 201. It becomes possible.

  That is, conventionally, all the piezoelectric elements provided on the touch panel 201 are uniformly vibrated with a predetermined vibration parameter regardless of the position of the user's touch position. In this case, vibration cancellation due to vibration interference occurred, and a portion that did not vibrate at all occurred.

  In the present invention, the piezoelectric element 601 in the vicinity of the position is vibrated strongly and the distant piezoelectric element 601 in the position is vibrated weakly in response to the touch position T of the user, so that the above-described vibration cancellation is difficult to occur. It is possible to obtain a click feeling no matter where the user touches.

  In the above description, the user's touch position T is the A area 600a, but the same applies to other areas. For example, as shown in FIG. 7B, when the touch position T of the user is the C area 600c, the detection unit 402 detects the touch position T included in the C area 600c, and the determination unit 403 Vibration parameters of each piezoelectric element 601 are determined so as to increase the vibration of the piezoelectric element 601 corresponding to 600c and weaken the vibration of the piezoelectric element 601 corresponding to the A and B regions 600a and 600b other than the C region 600c, The vibration means 404 vibrates each piezoelectric element 601 based on the determined vibration parameter. Accordingly, a click feeling can be obtained regardless of the position on the touch panel 201 that the user touches.

  By the way, when the detection unit 402 detects the touch position of the user, the detection unit 402 notifies the display unit 401 of the fact, and the display unit 401 that has received the notification receives an input of a key operation corresponding to the touch position of the user. The screen display is switched and the input of predetermined setting conditions is accepted.

  If the user presses the start key 205 after completing the input of the setting conditions, the display unit 401 accepts the press of the start key 205 and notifies the image forming unit 405 of the multi-function peripheral 100 to that effect. Upon receiving the notification, the image forming unit 405 executes image formation based on the input setting conditions.

  As described above, according to the present invention, when the touch panel is touched by the user, the detection unit 402 that detects the touch position of the user, and when the touch position is detected, the piezoelectric at a position close to the touch position of the user. Determining means 403 for determining the vibration parameter of each piezoelectric element so as to increase the vibration of the element and weaken the vibration of the piezoelectric element located far from the touch position, and each piezoelectric element based on the determined vibration parameter And a vibration means 404 for vibrating the element.

  This makes it possible to obtain a click feeling when touching any position on the touch panel. In particular, in the present invention, a touch panel having a large size (for example, 7 inches to 10 inches), and a single piezoelectric element cannot vibrate the entire touch panel, and the touch panel needs to be provided with a plurality of piezoelectric elements. When applied to, it is effective.

  In the embodiment of the present invention, the frequency corresponding to the frequency of the piezoelectric element is adopted as the vibration parameter. However, other vibration parameters may be used.

  For example, a duty ratio corresponding to the vibration time of the piezoelectric element may be employed. When the duty is adopted, in the table 604, the vibration information 606 corresponding to the area 605 in which the touch position is detected stores a duty ratio close to 1 (long) as strong vibration parameter information, In the vibration information 606 corresponding to the region 605 other than the region 605 where the touch position is detected, a duty ratio close to (short) 0 is stored as information with weak vibration parameters. Since the time during which the piezoelectric element is vibrated varies depending on the magnitude of the duty ratio, it is possible to prevent vibration cancellation due to vibration interference as much as possible.

  Moreover, you may employ | adopt the input voltage intensity | strength corresponding to the amplitude of a piezoelectric element. When the input voltage intensity is adopted, the vibration information 606 corresponding to the area 605 in which the touch position is detected in the table 604 has a high input voltage intensity (for example, several tens of volts) as information having a strong vibration parameter. In the vibration information 606 corresponding to the region 605 other than the region 605 where the touch position is detected, low input voltage intensity (for example, ten and several V or several V) is stored as information with weak vibration parameters. The Since the magnitude of the amplitude of the piezoelectric element is caused by the magnitude of the input voltage intensity, it is possible to prevent the occurrence of vibration cancellation due to vibration interference as much as possible as described above.

  Note that the number of various vibration parameters may be one, or two or three may be combined. For example, a high frequency, a long duty ratio, and a high input voltage intensity may be stored as information with a strong vibration parameter, and a low frequency, a short duty ratio, and a low input voltage intensity may be stored as information with a weak vibration parameter. Absent.

  In the embodiment of the present invention, the touch panel 201 is divided into three regions 600, two piezoelectric elements 601 a and 601 b are provided at both ends of each region 600, and the piezoelectric element 601 corresponding to one region 600 is combined into one IC. (Integrated circuit) Although configured to be controlled by 602, other configurations may be used. For example, the touch panel 201 may be subdivided into a plurality of regions 600, and one piezoelectric element and one IC may be assigned to each subdivided region. In such a configuration, although the number of members such as piezoelectric elements is increased, the vibration parameters can be finely adjusted for each piezoelectric element, so that occurrence of vibration cancellation due to vibration interference can be further suppressed. .

  In the embodiment of the present invention, the table 604 is provided with vibration parameters set in advance. However, the reference vibration parameter used as a reference for each operation unit 102 and the reference vibration used as the reference for the vibration corresponding thereto. A vibration detection sensor that detects the number and vibration on the touch panel 201 may be newly provided to correct the vibration parameters of the table 604 for each operation unit 102. That is, when the user performs a predetermined operation, the vibration unit 404 vibrates each piezoelectric element 600 based on the reference vibration parameter, and detects the vibration frequency of each piezoelectric element 600 by the vibration detection sensor. Then, the vibration unit 404 compares the detected frequency with the reference frequency to determine whether or not the two are equal. If the result of the determination is that they are not equal (for example, the detected vibration When the difference between the number and the reference frequency is larger than a predetermined value), the vibration unit 404 corrects the vibration parameter of the table 604 corresponding to the difference between the two. When the vibration means 404 corrects, for example, when the vibration frequency is larger than the reference frequency, the vibration parameter of the table 604 is decreased by the difference between the two, and the vibration frequency is smaller than the reference frequency. The vibration parameter of the table 604 is increased by the difference between the two. By providing such a correction function, it is possible to eliminate individual differences in the operation unit 102, eliminate variations in the mounting position and mounting method of the piezoelectric element 600, and reliably provide the user with a click feeling.

  In the embodiment of the present invention, the image forming process has been described. However, any process such as facsimile transmission may be used as long as the user needs to touch the touch panel 201.

  The present invention has been described with respect to the case where the operation unit 102 is applied to the multifunction peripheral 100. However, any device may be used as long as it is a touch panel operation device provided with a piezoelectric element. For example, the operation unit 102 (operation Even when applied to various image forming apparatuses, various image processing apparatuses, various image processing apparatuses, various image display apparatuses, and the like provided with the apparatus), the same effects can be obtained.

  In the embodiment of the present invention, the MFP 100 (operation unit 102) is configured to include each unit, but a program that realizes each unit is stored in a storage medium, and the storage medium is provided. It doesn't matter. In this configuration, the multi-function device 100 (operation unit 102) reads the program, and the multi-function device 100 (operation unit 102) realizes each of the means. In that case, the program itself read from the recording medium exhibits the effects of the present invention. Furthermore, it is possible to provide a method for storing the steps executed by each means in a hard disk.

  As described above, the operation device and the operation method according to the present invention are useful not only for an operation unit but also for a multifunction machine, a copier, a printer, and the like equipped with the operation unit. It is effective as an operating device and operating method that can be obtained.
