  According to a second aspect of the present invention, in the input device according to the first aspect, the reaction region set by the setting unit in association with the display information reduced by the reduction unit is changed to the display information displayed by the reduction unit. The image processing apparatus includes an area reduction unit that reduces the image based on a reduction rate smaller than the reduction rate. Here, in the present invention, it is assumed that the reduction ratio is “0” or more, and the reduction ratio “0” means equal magnification.

  According to a third aspect of the present invention, in the input device according to the first or second aspect, as the distance between the center of the display information detected by the display detection unit and the contact position becomes longer, the reduction unit The reduction ratio is set so that the reduction ratio of the detected display information is increased, and the detected display information is reduced at the reduction ratio.

  According to a fourth aspect of the present invention, in the input device according to any one of the first to third aspects, the display information includes a region image indicating a region where the display information is displayed on a display surface, and the display information. Processing information indicating the processing content associated with the corresponding reaction area, and the reduction means can reduce the area image and the processing information at different reduction ratios, and the reduction means The display information is reduced so that the reduction rate of the area image is equal to or higher than the reduction rate of the processing information.

  According to a fifth aspect of the present invention, in the input device according to any one of the first to fourth aspects, a plurality of the display information is displayed on the display surface, and the reduction means is controlled by the display detection means. All the display information displayed on the display surface is reduced based on the distance between one point in the detected display information and the contact position.

  According to a sixth aspect of the present invention, in the input device according to the fifth aspect, when the reaction region corresponding to one display information is touched on the first screen on which a plurality of the display information is displayed, the first While switching from one screen to a second screen on which display information related to the process associated with the contacted reaction area is displayed, a process for switching to the first screen in a state where the second screen is displayed is associated Display control means for switching from the second screen to the first screen when the reaction area is touched, and a contact position storage for storing the touch position when the reaction area corresponding to the one display information is touched And the display detection means switches to the first screen when the second screen switched from the first screen by the display control means is displayed. Among the plurality of display information displayed on the first screen switched by the display control means, from the contact position stored by the contact position storage means. Display information displayed at a close position is detected, and the reduction unit is associated with a process of switching to the first screen in a state where the second screen switched from the first screen is displayed by the display control unit. When the selected reaction area is touched, the display control means switches the distance based on the distance between one point in the display information detected by the display detection means and the contact position stored by the contact position storage means. All display information displayed on the first screen is reduced.

  The invention according to claim 7 is the input device according to any one of claims 1 to 6, wherein the reduction means is detected by the display detection means when the contact position is outside the reaction region. The detected display information is reduced based on a distance between one point in the display information and the contact position.

  The invention according to claim 8 is the input device according to any one of claims 1 to 7, further comprising size storage means for storing the size of the display information that has not been reduced by the reduction means. In the state where the display information detected by the display detection means is reduced, when the contact by the input medium is not detected for a predetermined time, the reduced display information is displayed in the size stored in the size storage means. It is characterized by that.

  The input control program according to claim 9, when the inside of the detection area is touched by an input medium, the touch panel for detecting the touch position, a display unit for displaying display information on a display surface on which the touch panel is superimposed, Within the detection area, a setting means for setting a plurality of reaction areas in association with each of a plurality of display information displayed on the display surface, and any one of the reaction areas set by the setting means Execution means for executing processing associated with the reaction area when contact with the input medium is detected, the plurality of reaction areas and the display information corresponding to each of the plurality of reaction areas An input control program that can be executed by a computer of an input device that displays the display information on the display surface so as to overlap, the computer being in contact with the input medium If detected, display detection means for detecting display information displayed at a position closest to the contact position among the plurality of display information, and one point in the display information detected by the display detection means, And reducing means for reducing the detected display information based on the distance to the contact position.

  According to the first and ninth aspects of the present invention, when the contact of the input medium is detected, the display information displayed at the position closest to the contact position is detected among the plurality of display information. . Then, the detected display information is reduced based on the distance between the one point in the detected display information and the contact position. In general, when the display information displayed on the display surface is small, the variation in the contact position in the display information is small, and when the display information is large, the variation in the contact position in the display information is large. Therefore, the display information is reduced based on the distance between one point and the contact position in the display information displayed at the position closest to the contact position, which is likely to be the display information desired by the user. Thus, the variation in the contact position can be reduced without being restricted by the display range of the display information, and as a result, erroneous operations can be reduced.

  According to the second aspect of the present invention, the reaction area set in association with the reduced display information is reduced based on a reduction rate smaller than the reduction rate of the display information. Thereby, for example, even when a plurality of display information is displayed adjacent to each other, the reaction area is reduced, so that the interval between the reaction areas corresponding to the plurality of display information is increased, resulting in an erroneous operation. Can be reduced. In addition, since the reduction ratio of the reaction area is smaller than that of the display information, the possibility of being in contact with the reaction area can be increased, and erroneous operations can be further reduced.

  According to the third aspect of the present invention, the longer the distance between the center of the display information displayed at the position closest to the contact position and the contact position among the plurality of display information, the closest to the contact position. The reduction rate is set so that the reduction rate of the display information displayed at the position is increased, and the display information is reduced at the reduction rate. As a result, the larger the variation in the contact position with respect to the center of the display information, the greater the reduction ratio. Therefore, the variation in the contact position with respect to the center of the display information becomes smaller regardless of the distance between the center of the display information and the contact position. Incorrect operation can be reduced.

  According to the fourth aspect of the present invention, the reduction rate of the area image indicating the area where the display information is displayed on the display surface is reduced in the processing information indicating the processing content associated with the reaction area corresponding to the display information. The display information is reduced so as to be equal to or greater than the rate. Thereby, since the change in the size of the processing information is smaller than that of the region image, a reduction in the visibility of the processing information by the user is suppressed, and erroneous operations can be reduced.

  According to the invention described in claim 5, all display information displayed on the display surface based on the distance between one point in the display information displayed at the position closest to the contact position and the contact position. Is reduced. Thereby, without being limited by the display range of the display information, the variation of the contact position is reduced with respect to all the display information, and erroneous operations can be further reduced.

  According to the sixth aspect of the present invention, when a reaction region corresponding to one display information on the first screen on which a plurality of display information is displayed is touched, the contact position is stored. When a reaction area associated with a process of switching to the first screen is touched in a state where the second screen switched from the first screen is displayed, among a plurality of display information displayed on the switched first screen The display information displayed at the position closest to the stored contact position is detected. Then, based on the distance between the one point in the detected display information and the stored contact position, all the display information displayed on the switched first screen is reduced. In general, when the reaction area associated with the process of switching to the first screen is touched while the second screen switched from the first screen is displayed, there is a high possibility that the user has made a mistake in the operation. The display information to be operated next is often different from that operated last time. Further, the distance between the contact position and one point in the display information often depends on the user's personal habit or the like. Therefore, among the plurality of display information displayed on the switched first screen, the distance between the one point in the display information displayed at the position closest to the stored contact position and the stored contact position. Based on this, all the display information displayed on the switched first screen is reduced, so that the variation of the contact position by the user is reduced, and erroneous operations in subsequent operations can be efficiently reduced.

  According to the seventh aspect of the present invention, when the contact position by the input medium is outside the reaction region, the distance between the one point in the display information displayed at the position closest to the contact position and the contact position is set. Based on this, the display information is reduced. As a result, when the contact position is outside the reaction area, that is, when the process desired by the user is not executed, the display information is reduced. And the number of erroneous operations can be reduced more efficiently. In particular, it is suitable when, for example, the user accidentally touches the outside of the reaction area due to a user's wrinkle or the like, despite the user trying to select a desired display button.

  According to the eighth aspect of the present invention, when the display information displayed at the position closest to the contact position is reduced and the contact by the input medium is not detected for a predetermined time, the reduced display information is stored in advance. It is displayed in the size of the stored display information that has not been reduced. Generally, when contact with an input medium is not detected for a predetermined time in a state where display information is reduced, there is a high possibility that a user who has used the input device has stopped using the input device. As a result, for example, when the input device is used by a plurality of people, when a user other than the user who was used when the display information was reduced, the display information that has not been reduced is displayed. Therefore, the convenience when the input device is used by a plurality of users is increased without being fixed to the variation in the contact position by one user.

(Input control processing)
Input control processing executed by the CPU 10 of the MFP 1 will be described with reference to FIGS. This input control process is repeatedly executed until the main power is turned off after the main power of the MFP 1 is turned on.

  In FIG. 2, rectangles 35 to 38 indicated by broken lines indicate reaction areas set in the detection area 171 of the touch panel 17 as in FIG. 1B, and are indicated by solid lines in the reaction areas 35 to 38. The rectangles 31 to 34 indicate display buttons corresponding to the reaction regions 35 to 38. In FIG. 2, as in FIG. 1B, the reaction areas 35 to 38 are illustrated for convenience of explanation, and are not displayed on the display surface 161.

  First, in S300 shown in FIG. 3, a plurality of reaction areas 35 to 38 are set in the detection area 171 in accordance with the coordinate information of the reaction area stored in advance in the coordinate management memory 112 (see FIG. 1A). Display buttons 31 to 34 corresponding to the set reaction regions 35 to 38 are displayed on the display surface 161 (S302).

  Specifically, first, in S300, it is stored in the coordinate management memory 112 in association with identification information of an operation screen (hereinafter referred to as “initial operation screen”) displayed when the main power is turned on. A plurality of reaction areas 35 to 38 are set in the detection area 171 in accordance with the coordinate information of the reaction areas 35 to 38. In step S <b> 302, the display buttons 31 to 34 stored in the ROM 11 in association with the set reaction areas 35 to 38 are displayed on the display surface 161 according to the coordinate information of the display buttons 31 to 34 stored in the coordinate management memory 112. Is displayed.

  Next, in S304, it is determined whether or not there is a contact. That is, in S304, it is determined whether or not contact within the detection area 171 by the input medium has been detected. When it is determined that there is no contact (S304: NO), the process of S304 is repeated until it is determined that there is a contact. When it is determined that there is a contact (S304: YES), the contact position where the contact by the input medium is detected is stored in the contact position memory 121 (S306). In S306, the contact position where the touch is detected by the touch panel 17 and the identification information of the operation screen displayed on the display surface 161 when the contact is detected are associated with each other and stored in the contact position memory 121.

  The shortest distance between the centers 210 to 240 of the plurality of display buttons 31 to 34 displayed on the display surface 161 and the position on the display surface 161 corresponding to the contact position stored in S306 is calculated (S308).

The shortest distance between 240 and the position on the display surface 161 corresponding to the contact position stored in S306 is calculated.

  Among the plurality of display buttons 31 to 34 displayed on the display surface 161, the display button displayed at the position closest to the contact position stored in S306 is detected (S310). In S310, among the shortest distances between the centers 210 to 240 of the display buttons 31 to 34 calculated in S308 and the position on the display surface 161 corresponding to the contact position, the display button having the shortest shortest distance is detected. In the present embodiment, in S310, detection is performed based on the shortest distance between the centers 210 to 240 of the display buttons 31 to 34 and the position on the display surface 161 corresponding to the contact position, but the present invention is not limited to this. First, for example, the shortest point between an arbitrary point in the area where the display buttons 31 to 34 are displayed, such as the vertices of the display buttons 31 to 34 stored in the coordinate management memory 121, and the position on the display surface 161 corresponding to the contact position. If it is a distance, various forms can be taken. The shortest distance between the center of the display button detected in S310 and the position on the display surface 161 corresponding to the contact position is associated with the identification information of the operation screen displayed on the display surface 161 when contact is detected in S304. And stored in the contact distance memory 122.

  In S312, it is determined whether or not the contact position where the contact in the detection area 171 is detected in S304 is in the reaction area. In S312, according to the coordinate information of the reaction areas 35 to 38 stored in the coordinate management memory 112, the contact position stored in S306 is one of the reaction areas 35 to 38 set in S300. It is determined whether it is located within 35-38. If it is determined that the contact position is not within the reaction region (S312: NO), the step process proceeds to S318.

  When it is determined that the contact position is within the reaction region (S312: YES), processing associated with the reaction region is executed (S314). In S314, the process associated with the reaction area including the contact position determined in S312 is read from the ROM 11 and executed. For example, in the initial operation screen shown in FIG. 2A, when the reaction area 38 corresponding to the copy button 34 is touched by the user, the copy function is executed. Here, execution of the copy function means that an operation screen (hereinafter referred to as “copy operation screen”) showing the detailed settings of the copy function shown in FIG. 2B is displayed on the display surface 161. Specifically, a plurality of reaction areas (not shown) stored in the coordinate management memory 112 in association with the identification information on the copy operation screen are set in the detection area 171, and the ROM 11 is associated with each of the reaction areas. Are displayed on the display surface 161. That is, a plurality of reaction areas stored in the coordinate management memory 112 in association with the identification information on the copy operation screen are set in the detection area 171, and display buttons stored in the ROM 11 are associated with the respective reaction areas. Processing to be displayed on the display surface 161 is stored in the ROM 11 in association with the reaction area 38.

  In S316 shown in FIG. 3, it is determined whether or not the return button 40 is touched. In the present embodiment, the plurality of operation screens stored in the ROM 11 include a screen in which a return button 40 is displayed as in the copy operation screen shown in FIG. 2B, for example. In S316, it is determined whether or not contact within the reaction region corresponding to the return button 40 has been detected.

  In the present embodiment, when a reaction region corresponding to any display button is touched on an operation screen (hereinafter referred to as “first screen”) on which a plurality of display buttons are displayed, the contact is started from the first screen. The screen is switched to an operation screen (hereinafter referred to as “second screen”) on which a display button related to the process associated with the reaction region is displayed. Then, when the reaction area associated with the process of switching to the first screen is touched in the state where the second screen is displayed, the second screen is switched to the first screen (corresponding to the display control means of the present invention). . The return button 40 is a display button corresponding to a reaction area associated with a process of switching to the first screen in a state where the second screen is displayed. For example, in the initial operation screen shown in FIG. 2A, when the reaction area 38 corresponding to the copy button 34 is touched, the initial operation screen is switched to the copy operation screen (see FIG. 2B). Then, when a reaction area (not shown) corresponding to the return button 40 is touched in a state where the copy operation screen is displayed, the copy operation screen is switched to the initial operation screen.

  As a result of the determination in S316 of FIG. 3, if it is determined that the return button 40 is not touched (S316: NO), the step process proceeds to S304. When it is determined that the back button 40 is touched (S316: YES), the display buttons 31 to 34 are reduced and displayed on the display surface 161 based on the distance stored in the contact distance memory 122 in S310 ( S318). In S318, on the operation screen displayed on the display surface 161 when contact is detected in S304, the display buttons 31 to 34 displayed on the operation screen are set to the distance stored in the contact distance memory 122 in S310. Based on this, it is displayed in a reduced size. For example, the reaction area 38 corresponding to the copy button 34 is touched on the initial operation screen shown in FIG. 2A, and the copy operation screen (see FIG. 2B) is displayed. When the reaction area (not shown) corresponding to the return button 40 is touched in the state where the copy operation screen is displayed (S316: YES), the copy operation screen is switched to the initial operation screen, and the initial operation screen is displayed. Are displayed in a reduced state (see FIG. 2C).

  In S318, first, the distance stored in S310 and the operation screen identification information stored in association with the distance are read from the contact distance memory 122. Based on the read identification information of the operation screen, the vertex and center coordinate information of the display buttons 31 to 34 is read from the coordinate management memory 112. Based on the distance read from the contact distance memory 122, the reduction ratios of all the display buttons 31 to 34 displayed on the operation screen corresponding to the read identification information are calculated. Specifically, the reduction rate is calculated so that the reduction rate of the display buttons 31 to 34 increases as the distance read from the contact distance memory 122 increases. For example, the reduction rate of the display buttons 31 to 34 is calculated to increase in direct proportion as the distance read from the contact distance memory 122 increases.

  The button images 45 to 48 can be reduced at different reduction rates from the processing images 41 to 44 of the display buttons 31 to 34 (see FIG. 1B), and the reduction rates of the button images 45 to 48 are the processing images. The reduction ratios are calculated so that the reduction ratios are 41 to 44 or more. Specifically, for example, based on a calculation method in which the reduction rate increases as the distance read from the contact distance memory 122 increases, the reduction rate of the processed images 41 to 44 and the reduction rate of the button images 45 to 48 are determined. Is calculated. Each reduction ratio is adjusted so that the calculated reduction ratio of the button images 45 to 48 is equal to or higher than the calculated reduction ratio of the processed images 41 to 44. As a method for adjusting the reduction ratio of the processed images 41 to 44 and the button images 45 to 48, it is preferable to reduce the calculated reduction ratio of the processed images 41 to 44 based on the calculated reduction ratios of the button images 45 to 48. It is. When the reduction rate of the processed images 41 to 44 is increased, it becomes difficult for the user to recognize the processed images 41 to 44. Therefore, it is preferable to calculate the reduction rate of the processed images 41 to 44 as small as possible.

  The coordinate information of the reduced processed images 41 to 44 and the button images 45 to 48 is calculated based on the calculated reduction ratio, and the display buttons 31 to 31 reduced on the display surface 161 based on the calculated coordinate information. 34 is displayed. In this embodiment, the reduction rate of the display buttons 31 to 34, that is, the reduction rate of the processed images 41 to 44 and the button images 45 to 48 is calculated as the distance read from the contact distance memory 122 is longer. As long as it is calculated so as to increase, various forms can be adopted.

  In S320, the reaction regions 35 to 38 are reduced. In S320, based on the identification information of the operation screen read from the contact distance memory 122 in S318, the coordinate information of the reaction areas 35 to 38 stored in association with the identification information is read from the coordinate management memory 112. A value smaller than the reduction ratio of the processed images 41 to 44 (see FIG. 1B) calculated in S318 is a reduction ratio of all the reaction areas 35 to 38 corresponding to the display buttons 31 to 34 reduced and displayed in S318. As determined. Then, the coordinate information of the reduced reaction areas 35 to 38 is calculated based on the determined reduction ratio. Based on the calculated coordinate information, the reduced reaction areas 35 to 38 are set in the detection area 171.

  In the present embodiment, various forms can be adopted as long as the reduction ratio of the reaction regions 35 to 38 is at least larger than 0 and smaller than the reduction ratio of the processed images 41 to 44 calculated in S318. For example, as illustrated in FIG. 2C, the display buttons 31 to 34 are reduced and displayed on the display surface 161. Further, the reaction areas 35 to 38 are reduced by a value smaller than the reduction ratio of the processed images 41 to 44 in the display buttons 31 to 34 and set to the detection area 171.

  In S322 shown in FIG. 3, it is determined whether or not there is a contact as in S304. If it is determined that there is a contact (S322: YES), the step process proceeds to S306. When it is determined that there is no contact (S322: NO), it is determined whether or not a predetermined time has elapsed since the process of S320 was executed (S324). If it is determined that the predetermined time has not elapsed (S324: NO), the step process proceeds to S322.

  When it is determined that the predetermined time has elapsed (S324: YES), the contact position and distance stored in the contact position memory 121 and the contact distance memory 122 are deleted (S326), the process returns to S300, and the step process is repeated.

  Here, the input control process shown in FIG. 3 will be specifically described using the operation screen shown in FIG. 2 as an example. FIG. 2A is a display example of an initial operation screen displayed on the display surface 161. FIG. 2B is a display example of a copy operation screen displayed on the display surface 161. FIG. 2C is a display example of the initial operation screen in which the display buttons 31 to 34 and the reaction areas 35 to 38 are reduced by executing the input control process. Note that the initial operation screen illustrated in FIG. 2A is the same as the operation screen illustrated in FIG.

  First, in the initial operation screen shown in FIG. 2A, the contact position 200 is touched by the input medium, the copy operation screen (see FIG. 2B) is displayed, and the return button 40 is displayed with the copy operation screen displayed. A case where a reaction region corresponding to the above is contacted (hereinafter referred to as “Example 1”) will be described.

  In accordance with the coordinate information of the reaction areas 35 to 38 and the display buttons 31 to 34 stored in the coordinate management memory 112 in association with the identification information on the initial operation screen, the reaction areas 35 to 38 are set in the detection area 171 and the display button 31 is displayed. To 34 are displayed on the display surface 161 (S300 to S302). Since the contact at the contact position 200 is detected (S304: YES), the coordinate information of the contact position 200 is associated with the identification information on the initial operation screen and stored in the contact position memory 121 (S306).

  The shortest distance between the centers 210 to 240 of the display buttons 31 to 34 and the position on the display surface 161 corresponding to the contact position 200 is calculated, and the copy button 34 having the shortest shortest distance is detected (S308 to S310). . In S <b> 310, the calculated shortest distance corresponding to the copy button 34 is stored in the contact distance memory 122.

  Since the contact position 200 is located inside the reaction area 38 (S312: YES), the copy function, which is a process associated with the reaction area 38, is executed, and the copy operation screen shown in FIG. Is displayed (S314).

  Since the reaction region corresponding to the return button 40 has been touched (S316: YES), the display buttons 31 to 34 are reduced and displayed on the display surface 161 as shown in FIG. 2C (S318).

  For example, in Example 1, the reduction ratio of the processed images 41 to 44 and the button images 45 to 48 is 40% based on the shortest distance between the center 240 of the copy button 34 and the position on the display surface 161 corresponding to the contact position 200. Suppose that it is calculated. The reduction rate of 40% indicates that the size is reduced to 60% of the size displayed on the display surface 161. Then, the reduction rate of the processed images 41 to 44 is adjusted to 35%, for example, so as to be smaller than the reduction rate of the button images 45 to 48. Therefore, the display buttons 31 to 34 in which the processed images 41 to 44 are reduced at a reduction rate of 38% and the button images 45 to 48 are reduced at a reduction rate of 40% are displayed on the display surface 161 (see FIG. 2C). ). That is, in S318, the processing images 41 to 44 reduced to 65% of the processing images 41 to 44 shown in FIG. 2A and the button images 45 to 48 shown in FIG. Display buttons 31 to 34 including button images 45 to 48 reduced to a size of 60% are displayed on the display surface 161.

  In S320, the reaction regions 35 to 38 are reduced (see FIG. 2C). For example, in Example 1, assuming that the reduction ratio of all the reaction regions 35 to 38 is determined to be 10% as a value that is at least greater than 0 and smaller than the reduction ratio 35% of the processed images 41 to 44 calculated in S318. As indicated by a broken line in FIG. 2 (C), reaction areas 35 to 38 reduced at a reduction rate of 10% are set as detection areas 171. That is, reaction regions 35 to 38 that are reduced to 90% of the size of reaction regions 35 to 38 shown in FIG.

  When contact in the detection area 171 by the input medium is detected (S322: YES), the step process is shifted to S306, and the processes after S306 are executed again. At this time, when the inside of the reaction region corresponding to the return button 40 is touched (S316: YES), the display buttons 31 to 34 are further reduced and displayed by the processing of S318 to S320, and the reaction corresponding to the display buttons 31 to 34 is performed. The areas 35 to 38 are reduced and set as the detection area 171. That is, when the contact by the input medium is detected in S322 (S322: YES) and the contact of the return button 40 is detected in S316 (S316: YES), the processes of S306 to S322 are repeated, and the display surface 161 is displayed. The displayed display buttons 31 to 34 and the corresponding reaction areas 35 to 38 are reduced as the processing is repeated.

  In such a case, it is highly likely that the touch of the return button 40 has been repeatedly detected because the user has made a mistake. Further, as one of the causes that the user makes a mistake in operation, there is a variation in the contact position with respect to the display button. Therefore, as the contact of the return button 40 is repeatedly detected, the display buttons 31 to 34 and the reaction areas 35 to 38 are reduced, so that the contact position with respect to the display buttons 31 to 34 is stopped until the user does not touch the return button 40. The variation in the gradual decrease gradually reduces the number of erroneous operations. Further, even when the user makes a mistake and operates another display button in the next operation, all the display buttons 31 to 34 displayed on the display surface 161 and all set in the detection area 171 are displayed. Since the reaction regions 35 to 38 are reduced, it is possible to further reduce erroneous operations in subsequent operations.

  In addition, even when contact by the input medium is detected (S322: YES) and the contact position is not included in any of the reaction regions 35 to 38 set in the initial operation screen (S312: NO), The processes of S306 to S322 are repeated, and the display buttons 31 to 34 displayed on the display surface 161 are reduced and displayed (S318). The reaction areas 35 to 38 corresponding to the display buttons 31 to 34 are also reduced and set to the detection area 171 (S320).

  On the other hand, when a predetermined time has elapsed since the process of S320 was executed (S322: NO, S324: YES), the contact position and distance stored in the contact position memory 121 and the contact distance memory 122 are deleted (S326). Returning to S300, the step process is repeated. That is, as shown in FIG. 2C, the reduced reaction areas 35 to 38 and the display buttons 31 to 34 are shown in FIG. 2A based on the coordinate information stored in the coordinate management memory 112. Thus, the size of the operation screen before the reduction is in the initial state (S302 to S304). Then, in the state where the initial operation screen shown in FIG. 2A is displayed on the display surface 161, the processes of S304 to S326 are executed again.

  Next, a case where the contact position 202 is touched by the input medium on the initial operation screen shown in FIG. 2A (hereinafter referred to as “example 2”) will be described. The contact position 202 is a position that is not included in any of the reaction areas 35 to 38 corresponding to the display buttons 31 to 34 shown in FIG. That is, when the contact position 202 is touched by the input medium, the operation desired by the user is not executed and an erroneous operation is performed.

  As in the case of Example 1, the reaction areas 35 to 38 are set in the detection area 171 according to the coordinate information stored in the coordinate management memory 112 in association with the identification information on the initial operation screen, and the display buttons 31 to 34 are displayed. The surface 161 is set (S300 to S302). Since contact by the input medium is detected at the contact position 202 (S304: YES), the coordinate information of the contact position 202 is associated with the identification information on the initial operation screen and stored in the contact position memory 121 (S306).

  The shortest distance between the centers 210 to 240 of the display buttons 31 to 34 and the position on the display surface 161 corresponding to the contact position 202 is calculated, and the copy button 34 having the shortest shortest distance is detected (S308 to 310). . Similar to Example 1, in S 310, the calculated shortest distance corresponding to the copy button 34 is stored in the contact distance memory 122.

  Since the contact position 202 is not included in any of the reaction areas 35 to 38 set on the initial operation screen (S312: NO), as shown in FIG. 2C, the display buttons 31 to 34 are displayed. Is reduced and displayed on the display surface 161 (S318).

  For example, the shortest distance between the center 240 of the copy button 34 in Example 2 and the position on the display surface 161 corresponding to the contact position 202 is the position on the display surface 161 corresponding to the center 240 of the copy button 34 and the contact position 200 in Example 1. Is 1.5 times the shortest distance between the processed images 41 to 44 and the button images 45 to 48 in Example 2, the reduction rate of the button images 45 to 48 in Example 1 is directly proportional to 40%. , 60%. Then, the reduction rate of the processed images 41 to 44 is adjusted to 55%, for example, so as to be smaller than the reduction rate of the button images 45 to 48. Therefore, the display buttons 31 to 34 in which the processed images 41 to 44 are reduced at a reduction rate of 55% and the button images 45 to 48 are reduced at a reduction rate of 60% are displayed on the display surface 161 (see FIG. 2C). ). That is, in S318, the processing images 41 to 44 reduced to 45% of the processing images 41 to 44 shown in FIG. 2A and the button images 45 to 48 shown in FIG. Display buttons 31 to 34 including button images 45 to 48 reduced to a size of 40% are displayed on the display surface 161.

  In S320, the reaction regions 35 to 38 are reduced (see FIG. 2C). For example, in Example 1, assuming that the reduction ratio of all the reaction regions 35 to 38 is determined to be 20% as a value that is greater than at least 0 and smaller than the reduction ratio 55% of the processed images 41 to 44 calculated in S318. As indicated by a broken line in FIG. 2 (C), reaction areas 35 to 38 reduced at a reduction rate of 20% are set in the detection area 171. That is, reaction regions 35 to 38 that are reduced to 80% of the size of reaction regions 35 to 38 shown in FIG.

  Note that FIG. 2C is an example of reduced display in Example 1 and Example 2. For convenience of explanation, Example 1 and Example 2 have been described with reference to FIG. 2C, and FIG. 2C shows the reduction ratios of the display buttons 31 to 34 and reaction regions 35 to 38 calculated in Example 1 and Example 2. It is not directly reflected. Further, the present invention is not limited to the reduction rate calculation method as in Example 1 and Example 2, and can take various forms. For example, the reduction rate of the display buttons 31 to 34 is calculated so that the reduction rate increases as the distance read from the contact distance memory 122 increases, and the reduction rate of the button images 45 to 48 is the processed image 41. Display buttons 31 to 34 displayed in a reduced manner in the case of Example 1 and reduced display in the case of Example 2 as long as the reduction is performed based on the reduction rate adjusted to be equal to or higher than the reduction rate of .about.44. The display buttons 31 to 34 may be the same size. Further, if the reduction ratio of the reaction areas 35 to 38 is reduced based on a reduction ratio that is at least greater than 0 and smaller than the reduction ratio of the processed images 41 to 44 calculated in S318, for example, The reaction areas 35 to 38 reduced in the case of Example 1 and the reaction areas 35 to 38 reduced in the case of Example 2 may have the same size.

  Similarly to Example 1, when contact in the detection area 171 by the input medium is detected (S322: YES), the step process proceeds to S306, and the processes of S306 to S312 are executed again. When the contact position detected in S322 is not included in any of the reaction areas 35 to 38 set on the initial operation screen like the contact position 202 (S312: NO), S318 to S320. Through the process, the display buttons 31 to 34 are further reduced and displayed, and the reaction areas 35 to 38 corresponding to the display buttons 31 to 34 are reduced and set to the detection area 171. That is, when the contact by the input medium is detected in S322 (S322: YES) and the contact position is not included in any of the reaction areas 35 to 38 set in the initial operation screen (S312: NO), The processes of S306 to S322 are repeated, and the display buttons 31 to 34 displayed on the display surface 161 and the corresponding reaction areas 35 to 38 are reduced as the process is repeated.

  In this case, as the positions not included in the reaction areas 35 to 38 are touched, the display buttons 31 to 34 and the reaction areas 35 to 38 are reduced. Until it is executed, the display buttons 31 to 34 and the reaction areas 35 to 38 are reduced. Therefore, since the display buttons 31 to 34 are displayed at the maximum size among the sizes of the display buttons 31 to 34 that can surely execute the operation desired by the user, it is possible to suppress a decrease in the visibility of the display buttons 31 to 34. Meanwhile, the operability of the MFP 1 can be improved.

  In addition, when contact with the input medium is detected (S322: YES) and contact with the return button 40 is detected (S316: YES), the processing of S306 to S322 is repeated and displayed on the display surface 161. The displayed buttons 31 to 34 and the corresponding reaction areas 35 to 38 are reduced.

  On the other hand, as in Example 1, when the predetermined time has elapsed since the process of S320 was executed (S322: NO, S324: YES), the contact position and distance stored in the contact position memory 121 and the contact distance memory 122 are After being erased (S326), the process returns to S300 and the step process is repeated.

  As described above, according to the present embodiment, when contact with an input medium is detected (S304: YES shown in FIG. 3), the display buttons 31 to 34 are positioned closest to the contact position. The displayed display buttons 31 to 34 are detected (see S310 shown in FIG. 3). Then, the detected display button is reduced based on the distance between the one point on the detected display button and the contact position (see S318 shown in FIG. 3). In general, when the display buttons 31 to 34 displayed on the display surface 161 are small, the variation in the contact position of the display buttons 31 to 34 is small. When the display buttons 31 to 34 are large, the display buttons 31 to 34 are large. The variation of the contact position becomes large. Therefore, based on the distance between one point and the contact position in the display buttons 31 to 34 displayed at the position closest to the contact position, which is likely to be the display buttons 31 to 34 desired by the user, the display button By reducing 31 to 34, the variation in the contact position can be reduced without being limited by the display range of the display buttons 31 to 34, and as a result, erroneous operations can be reduced.

  Here, all the display buttons 31 to 34 displayed on the display surface 161 are based on the distance between one point on the display buttons 31 to 34 displayed closest to the contact position and the contact position. More preferably, it is reduced. In such a case, since the variation in the contact position is reduced with respect to all the display buttons 31 to 34 without being limited by the display range of the display buttons 31 to 34, the erroneous operation can be further reduced in the subsequent operations. it can.

  Moreover, it is more preferable that one point in the display buttons 31 to 34 is the centers 210 to 240 of the display buttons 31 to 34. In such a case, the display buttons 31 to 34 are reduced based on the distance between the centers 210 to 240 of the display buttons 31 to 34 and the contact positions, so that the variation in the contact positions with respect to the display buttons 31 to 34 desired by the user is further increased. It can be uniformly reduced.

  The reaction areas 35 to 38 set in association with the reduced display buttons 31 to 34 are reduced based on a reduction ratio larger than at least 0 and smaller than the reduction ratio of the display buttons 31 to 34 (shown in FIG. 3). (See S320). Thereby, for example, as shown in FIG. 2A, even when the plurality of display buttons 31 to 34 are displayed adjacent to each other, the reaction regions 35 to 38 are reduced, so that FIG. As shown in C), the interval between the reaction areas 35 to 38 corresponding to the plurality of display buttons 31 to 34 is increased, and erroneous operations can be reduced. In addition, since the reduction ratio of the reaction areas 35 to 38 is smaller than that of the display buttons 31 to 34, the possibility of being in contact with the reaction areas 35 to 38 can be increased, and erroneous operations can be further reduced.

  Of the plurality of display buttons 31 to 34, the longer the distance between the center of the display buttons 31 to 34 displayed at the position closest to the contact position and the contact position, the closer to the contact position, the more the display button 31 to 34 is displayed. The reduction rate is set so that the reduction rate of the displayed button is increased, and the display button is reduced at the reduction rate (see S318 shown in FIG. 3). As a result, the larger the variation in the contact position with respect to the centers of the display buttons 31 to 34, the greater the reduction ratio. Therefore, the variation in the contact position with respect to the center of the display information regardless of the distance between the center of the display information and the contact position. Can be reduced.

  The display buttons 31 to 34 are based on the reduction rates of the button images 45 to 48 and the processed images 41 to 44 that are determined so that the reduction rates of the button images 45 to 48 are equal to or higher than the reduced rates of the processed images 41 to 44. The image is reduced (see S318 shown in FIG. 3). Thereby, since the change of the magnitude | size of the process images 41-44 becomes small compared with the button images 45-48, the fall of the visibility of the process images 41-44 by a user is suppressed, and an erroneous operation can be reduced.

  When the reaction areas 35 to 38 corresponding to one display button on the first screen on which the plurality of display buttons 31 to 34 are displayed are touched, the contact positions are stored in the contact position memory 121 (shown in FIG. 3). (See S306). The return button 40 is a display button corresponding to a reaction area associated with a process of switching to the first screen in a state where the second screen is displayed. When the reaction region corresponding to the return button 40 is touched in a state where the second screen switched from the first screen is displayed (S316: YES shown in FIG. 3), a plurality of displayed on the switched first screen Among the display buttons 31 to 34, the display button displayed at the position closest to the stored contact position is detected. All the display buttons 31 to 34 displayed on the switched first screen are reduced based on the distance between the detected point on the display buttons 31 to 34 and the stored contact position. In general, when the reaction area corresponding to the return button 40 is touched while the second screen switched from the first screen is displayed, it is highly likely that the user has made a mistake in the operation, and the next operation The displayed button is often different from the last operated button. In addition, the distance between the contact position and one point on the display buttons 31 to 34 often depends on the user's personal habit or the like. Therefore, among the plurality of display buttons 31 to 34 displayed on the switched first screen, one point on the display button displayed at the position closest to the stored contact position, and the stored contact position All the display buttons 31 to 34 displayed on the switched first screen are reduced based on the distance, thereby reducing the variation in the contact position by the user and efficiently reducing erroneous operations in subsequent operations. Can be made.

  When the contact position by the input medium is located outside the reaction regions 35 to 38 (S312: NO shown in FIG. 3), one point on the display buttons 31 to 34 displayed closest to the contact position and the contact Based on the distance to the position, the display buttons 31 to 34 are reduced (see S318 shown in FIG. 3). Thereby, when the contact position is located outside the reaction areas 35 to 38, the variation of the contact position in the display buttons 31 to 34 is reduced. For example, even though the user tries to select a desired display button. First, erroneous operations can be reduced particularly effectively when the outside of the reaction area is accidentally touched by a user's habit or the like.

  In a state where the display buttons 31 to 34 displayed at positions closest to the contact position are reduced, when contact by the input medium is not detected for a predetermined time (S324 shown in FIG. 3: YES), the reduced display buttons 31 to 31 are displayed. 34 is displayed in the size of the display buttons 31 to 34 that have not been reduced based on the coordinate information stored in the coordinate management memory 112. In general, when contact with an input medium is not detected for a predetermined time in a state where the display buttons 31 to 34 are reduced, it is highly likely that a user who has used the MFP 1 has stopped using the MFP 1. As a result, for example, when the MFP 1 is used by a plurality of people, when the user who is different from the user who is used when the display buttons 31 to 34 are reduced, the display buttons 31 to 31 that are not reduced are used. 34 is displayed, the convenience when the MFP is used by a plurality of users is increased without being fixed to the variation in the contact position by one user.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various aspect can be taken in the range which does not deviate from the summary of this invention.

  In the present embodiment, the MFP 1 has been described as an example of the input device and the input control program of the present invention. However, the present invention is not limited to this, and various modes can be adopted as long as it has a touch panel.

  In this embodiment, the reaction regions 35 to 38 are reduced in S320 shown in FIG. 3, but the present invention is not limited to this, and for example, the size of the reaction regions 35 to 38 is not changed. Alternatively, the reaction regions 35 to 38 set in the detection region 171 may be enlarged so as not to overlap each other.

  In this embodiment, in S318 shown in FIG. 3, all the display buttons 31 to 34 displayed on the operation screen on the operation screen displayed on the display surface 161 when contact is detected in S304 are reduced and displayed. However, the present invention is not limited to this, and at least one of the display buttons 31 to 34 displayed on the operation screen displayed on the display surface 161 when contact is detected in S304. It suffices if one of them is reduced. For example, only the display button closest to the contact position touched in S304 may be reduced and displayed. In such a case, for a user who has many erroneous operations with respect to a specific display button, since only the display button is displayed in a reduced size, variation in the contact position with respect to the display button is reduced, thereby efficiently reducing erroneous operations. Can be made.

  In the present embodiment, when the outside of the reaction regions 35 to 38 is contacted (S312: NO shown in FIG. 3), or the inside of the reaction regions 35 to 38 is contacted by an input medium (S312: YES shown in FIG. 3), When the process associated with the contacted reaction area is executed (see S314 shown in FIG. 3) and the inside of the reaction area corresponding to the return button 40 is touched (S316: YES shown in FIG. 3), display Buttons 31-34 and reaction areas 35-38 were reduced. However, the present invention is not limited to this, and the reaction regions 35 to 38 are contacted (S312: YES shown in FIG. 3), and the process associated with the contacted reaction region is executed (FIG. 3). The display buttons 31 to 34 and the reaction areas 35 to 38 may be reduced even when the reaction area corresponding to the return button 40 is not touched.

  In such a case, when the operation screen (see S312 shown in FIG. 3) displayed on the display surface 161 when contact in the reaction areas 35 to 38 is detected is displayed again on the display surface 161, the display button and The reaction area may be reduced, or the display button and the reaction area displayed on the display surface 161 in a state where the execution of the process associated with the contacted reaction area is completed may be reduced.

  In the latter case, the contact is made based on the shortest distance between the contact position and one of the display buttons 31 to 34 displayed on the display surface 161 when the contact is made. The display button and the reaction area displayed on the display surface 161 are reduced in a state where the execution of the process associated with the reaction area is completed. In general, since the displacement of the contact position with respect to the display buttons 31 to 34 often depends on the user's eyelid, the execution of the process associated with the contacted reaction region is completed based on the detected displacement of the contact position. By reducing the display button and the reaction area displayed on the display surface 161 in a state where the operation has been performed, erroneous operations in subsequent operations can be effectively reduced. Note that the state in which execution of the process associated with the contacted reaction area is completed means, for example, that the contact position 200 is touched by the input medium on the initial operation screen shown in FIG. 2 (B)) is displayed.

  In the present embodiment, the processed images 41 to 44 are indicated by character strings “print”, “FAX”, “scan”, and “copy” as shown in FIG. As long as it shows the contents of the processing associated with the reaction areas 35 to 38 corresponding to .about.34, various forms such as images and marks can be adopted. In the present embodiment, the button images 45 to 48 are shown as rectangular figures that are the outer shapes of the display buttons 31 to 34 as shown in FIG. 1B, but show the outer shape of the display buttons. If it is a thing, various forms, such as a polygon and a circle, can be taken, for example.

  In the flowchart of FIG. 3, S306 corresponds to the contact position storage means of the present invention, S310 corresponds to the display detection means of the present invention, S318 corresponds to the reduction means of the present invention, and S320 corresponds to the area reduction means of the present invention.
