  However, the conventional technique described above has the following problems. For example, by providing an invalid input unit that invalidates input to the input unit by contact between adjacent input units, when the user touches the adjacent input unit and the invalid input unit simultaneously, the adjacent input unit Simultaneous input to the part can be disabled. However, even if the user is in contact with the invalid input unit, the user may desire simultaneous input to adjacent input units. In other words, for example, when a user touches an individual input unit with two fingers but accidentally touches an invalid input unit, it is problematic to invalidate simultaneous input to adjacent input units. It becomes. This problem becomes more prominent as the interval between adjacent input units is narrower.

  The present invention has been made to solve the above-described problems of the prior art. That is, an object of the present invention is to provide a technology that is an input device having a plurality of input units, and that achieves both suppression of erroneous input and ease of simultaneous input to the plurality of input units. .

  An input device made to solve this problem includes a first input having a first surface and a first electrode that is an electrode that outputs a first output value in response to contact of an object with the first surface. A second electrode that is disposed in a first direction from the first input unit and that outputs a second output value in response to contact of an object with the second surface. A second input unit having a first intermediate output value according to contact of an object with the first intermediate surface and the first intermediate surface, the second intermediate unit being disposed between the first input unit and the second input unit. A first intermediate input unit having a first intermediate electrode that is an output electrode; and a control unit, wherein the control unit has a first detection value that is a detection value based on the first output value, A first input determination process for determining whether or not the threshold value is greater than a threshold value, and a second detection value that is a detection value based on the second output value. Second input determination processing for determining whether or not the second threshold value is greater than the second threshold value, and whether or not a first intermediate detection value that is a detection value based on the first intermediate output value is greater than the first intermediate threshold value A first intermediate input determination process, a determination that the first detection value is greater than the first threshold, a determination that the second detection value is greater than the second threshold, and the first Detection value determination for determining whether or not both of the first detection value and the second detection value are larger than the first intermediate detection value when it is determined that the intermediate detection value is larger than the first intermediate threshold value When it is determined that both the first detection value and the second detection value are larger than the first intermediate detection value, the input due to the contact of an object is applied to both the first surface and the second surface. The first simultaneous input signal that is a signal indicating that there was A first simultaneous input signal output process that does not output the first simultaneous input signal when it is not determined that at least one of the first detection value and the second detection value is greater than the first intermediate detection value; It is characterized by performing.

  In the input device disclosed in this specification, when there is input on all of the first surface, the second surface, and the first intermediate surface, the two surfaces of the first surface and the second surface And the detected value of the first intermediate surface are compared. When the detection values on the two surfaces are larger than the detection values on the first intermediate surface, the objects are in contact with the first surface and the second surface, respectively, and a part of the objects protrudes to the first surface. 1 is assumed to be in contact with the intermediate surface. Therefore, the input device outputs the first simultaneous input signal as the simultaneous input. On the other hand, when the detected value on the first intermediate surface is larger, one object contacts the first surface, the first intermediate surface, and the second surface, and the first intermediate surface is the center of the three surfaces. It is assumed that the detection value at is the highest. Therefore, the input device does not perform simultaneous input and does not output the first simultaneous input signal. That is, the input device disclosed in the present specification can preferably determine whether or not there is simultaneous input to the first surface and the second surface when detecting input by contact of an object on all three surfaces.

  In addition, the control unit determines that the first detection value is greater than the first threshold value, determines that the second detection value is not greater than the second threshold value, and the first intermediate value. When it is determined that the detected value is not larger than the first intermediate threshold value, a first input signal that is a signal indicating that there is an input due to contact with an object on the first surface is output, and the first detection is performed. It is determined that the value is greater than the first threshold, the second detection value is determined not to be greater than the second threshold, and the first intermediate detection value is greater than the first intermediate threshold. If it is determined, the first input signal output process that does not output the first input signal may be executed. When there is an input due to an object contact on the first surface and no input due to an object contact on the second surface, there is no need to determine simultaneous input. Therefore, based on the presence / absence of input due to contact of the object with the first intermediate surface, it is determined that there is input due to contact of the object with the first surface. It can be judged with higher accuracy.

  The first direction may be a direction from the front to the back of the input device. When the user inputs a finger to the input device, an erroneous input is more likely to occur in the direction from the front to the back than in the direction from the left to the right. Therefore, it is preferable to increase the detection accuracy particularly in the direction from the front to the back.

  The input device disclosed in the present specification is arranged in a second direction orthogonal to the first direction from the first electrode, and responds to contact of an object with the third surface and the third surface. A third input portion having a third electrode which is an electrode for outputting a third output value, and is disposed between the first input portion and the third input portion, a second intermediate surface, A second intermediate input unit having a second intermediate electrode that is an electrode that outputs a second intermediate output value in response to the contact of the object with the second intermediate surface, and the control unit includes the third output value. A third input determination process for determining whether a third detection value that is a detection value based on the second detection value is greater than a third threshold; and a second intermediate detection value that is a detection value based on the second intermediate output value, A second intermediate input determination process for determining whether or not the second intermediate threshold value is greater than the second intermediate threshold value; and the first detection value is greater than the first threshold value. When it is determined that the third detection value is greater than the third threshold value and the second intermediate detection value is determined not to be greater than the second intermediate threshold value, A second simultaneous input signal, which is a signal indicating that there has been an input due to contact with an object on both the first surface and the third surface, is output, and it is determined that the first detection value is greater than the first threshold value. And the second simultaneous input when it is determined that the third detection value is greater than the third threshold value and the second intermediate detection value is greater than the second intermediate threshold value. A second simultaneous input signal output process that does not output a signal may be performed. On the surface arranged in the left-right direction, it is easier to place fingers for simultaneous input than in the direction from the front to the back. Therefore, in the left-right direction, when there is an input on the second intermediate surface between the first surface and the third surface, the detected value is in a magnitude relationship with the detected values on the first surface and the third surface. Regardless, it is better not to use simultaneous input.

  In addition, the input device disclosed in the present specification is arranged in the first direction from the third electrode, and outputs a fourth output value according to the fourth surface and the contact of the object with the fourth surface. A fourth input portion having a fourth electrode that is an electrode to be operated; and a third input portion disposed between the third input portion and the fourth input portion. A third intermediate input portion having a third intermediate electrode which is an electrode for outputting a third intermediate output value in response to the contact, and the first intermediate electrode is electrically connected to the third intermediate electrode. It is good to be. By using the first intermediate electrode in common with the third intermediate electrode, the configuration is simplified.

  The first intermediate threshold value may be larger than the second intermediate threshold value. The first intermediate threshold value used for input detection of the first intermediate surface in the direction from the front side to the back side is made larger than the second intermediate threshold value used for input detection of the second intermediate surface in the left-right direction, thereby moving from the front side to the back side. In the direction, since it is determined that there is an input when there is stronger contact on the first intermediate surface, it is possible to further reduce false detection due to contact of an object with the first intermediate surface.

  The first ratio that is the ratio of the first detection value to the first output value and the second ratio that is the ratio of the second detection value to the second output value are the first intermediate value. The detection value may be smaller than a first intermediate ratio that is a ratio of the detected value to the first intermediate output value. By making the output ratio of the first intermediate electrode larger than the output ratio of the first electrode and the second electrode, it is possible to detect the input to the first intermediate electrode with high accuracy, and thus it is possible to detect erroneous input with high accuracy.

  The input device disclosed in the present specification is disposed on the opposite side of the first input portion in the first direction with the first input portion interposed therebetween, and includes a fourth intermediate surface, and the fourth intermediate surface. A fourth intermediate input portion having a fourth intermediate electrode that is an electrode that outputs a fourth intermediate output value in response to the contact of the object with the surface; and the first direction in the first direction across the second input portion A fifth intermediate electrode disposed on the opposite side of the first intermediate input portion and having a fifth intermediate surface and an electrode that outputs a fifth intermediate output value in response to the contact of the object with the fifth intermediate surface; A third intermediate input unit, wherein the control unit determines whether a fourth intermediate detection value that is a detection value based on the fourth intermediate output value is greater than a fourth intermediate threshold value. The fifth intermediate detection value that is a detection value based on the input determination process and the fifth intermediate output value is less than the fifth intermediate threshold value. A fourth intermediate input determination process for determining whether or not the output signal is satisfied; and a determination result of the third intermediate input determination process and a detection result of the fourth intermediate input determination process when the output condition of the first simultaneous input signal is satisfied It is recommended to execute invalidation processing for invalidating. When performing simultaneous input, the user tends to input his / her finger apart, and there is a high possibility that the finger protrudes outside the two surfaces to be simultaneously input. Particularly in the first direction, the finger tends to protrude outward. Therefore, when the output condition of the first simultaneous input signal is satisfied, it is preferable to invalidate the detection results of the fourth intermediate surface and the fifth intermediate surface outside the two surfaces to be simultaneously input.

  In addition, the first input unit and the second input unit are configured in a laminated structure in the order of at least an electrode, an intermediate, a cover having the first surface and the second surface, and the first intermediate input unit includes: It is preferable that at least an electrode, an object or air layer having a dielectric constant lower than that of the intermediate, and a cover having the first intermediate surface are stacked in this order. If the first input unit and the second input unit have the same structure as the first intermediate input unit, for example, input to the first surface tends to affect detection of input to the second electrode. Therefore, in order to reduce the influence of the input between the adjacent surfaces, an object or air layer having a low dielectric constant is disposed between the first intermediate surface and the first intermediate electrode, and the first surface and the second It is preferable to increase the detection accuracy of the input to the surface.

  A control method for realizing the functions of the image forming apparatus, a computer program, and a computer-readable storage medium storing the computer program are also novel and useful.

  According to the present invention, it is an input device having a plurality of input units, and a technique that achieves both suppression of erroneous input and easy simultaneous input to the plurality of input units is realized.

  In the present embodiment, the vertical direction in FIG. 2, that is, the direction from the front to the back of the operation panel 40 is defined as the first direction, and the horizontal direction in FIG. 2, that is, the direction orthogonal to the first direction, The second direction is assumed. For convenience of explanation, when the input units 50A, 50B, 50C, 50D, 50E, and 50F are not specified, they are simply referred to as “input unit 50”. The input unit 50 is an example of a first input unit, a second input unit, a third input unit, and a fourth input unit. When the input surfaces 45A, 45B, 45C, 45D, 45E, and 45F are not specified, they are simply referred to as “input surface 45”. The input surface 45 is an example of a first surface, a second surface, a third surface, and a fourth surface.

  The input units 50A, 50B, 50C, 50D, 50E, and 50F are arranged in the first direction or the second direction. Specifically, in the operation panel 40, the input unit 50A, the input unit 50B, and the input unit 50C have the same position in the second direction. In the first direction, the input unit 50A, the input unit 50B, and the input unit 50C are arranged in this order. Further, the input unit 50D, the input unit 50E, and the input unit 50F have the same position in the second direction. In the first direction, the input unit 50D, the input unit 50E, and the input unit 50F are arranged in this order. Further, the input unit 50A and the input unit 50D have the same position in the first direction. The input unit 50B and the input unit 50E have the same position in the first direction. The input unit 50C and the input unit 50F have the same position in the first direction.

  Each of the input units 50 is assigned as a selection button for various functions. On the input surface 45 of the input unit 50, symbols and symbols indicating functions assigned to the input units 50 are printed. Although this embodiment includes six input units 50, the number of input units 50 is not limited to six, and may be more or less than six.

  FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2 and shows the configuration of the input units 50A and 50B and their surroundings. In the present embodiment, the vertical direction in FIG. 3, that is, the thickness direction of the operation panel 40 is defined as the third direction.

  The operation panel 40 includes a substrate 42 and a cover 49. In the range corresponding to the input unit 50A in the operation panel 40, an electrode 43A located on the substrate 42 and a lens 44A located between the electrode 43A and the cover 49 are disposed. The lens 44A is provided to allow light from a backlight (not shown) provided on the substrate 42 to pass through and to emit the input surface 45A. In the range corresponding to the input unit 50B in the operation panel 40, an electrode 43B located on the substrate 42 and a lens 44B located between the electrode 43B and the cover 49 are disposed. Other input units 50C, 50D, 50E, and 50F (not shown) have the same configuration as the input units 50A and 50B. The electrodes and lenses included in the input unit 50 are also referred to as “electrode 43” and “lens 44”, respectively, when the individual input units are not specified. The electrode 43 is an example of a first electrode, a second electrode, a third electrode, and a fourth electrode.

  The input unit 50 is a capacitance type switch, and outputs a voltage value based on the capacitance of the capacitor constituted by the cover 49, the lens 44, and a contact object in contact with the input surface 45A from the electrode 43. To do. Specifically, the input unit 50 includes a cover 49, a lens 44, and an electrode 43 in the third direction from the input surface 45, and the input surface 45, which is a part of the surface of the cover 49, has a user's surface. Different voltage values are output from the electrode 43 depending on whether an object such as a finger is in contact with the object or not. The MFP 100 determines whether or not there is an input to the input unit 50 based on whether or not the output value from the electrode 43 exceeds a threshold value.

  In addition, the operation panel 40 includes an intermediate input unit 51X between the input unit 50A and the input unit 50B. Similarly to the input unit 50, the intermediate input unit 51X is a capacitive switch, and includes an intermediate electrode 46X on the substrate 42. The intermediate input unit 51X outputs different voltage values from the intermediate electrode 46X depending on whether or not an object is in contact with the intermediate input surface 48X that is a part of the surface of the cover 49.

  Unlike the input unit 50, the intermediate input unit 51X does not include a lens between the cover 49 and the intermediate electrode 46X. Therefore, the intermediate input unit 51X outputs, from the intermediate electrode 46X, a voltage value based on the capacitance of a capacitor constituted by the cover 49, the air layer 47, and a contact object that contacts the intermediate input surface 48X. . In the intermediate input unit 51X, by providing the air layer 47 having a dielectric constant lower than that of the lens, interference of electrostatic capacitance between the input unit 50A and the input unit 50B is suppressed, and the input unit 50A and the input unit 50B are connected. Increase the detection accuracy of input. It should be noted that any object other than the air layer 47 can be applied as long as it has a lower dielectric constant than the lens 44 of the input unit 50.

  In the operation panel 40, an intermediate input unit is disposed between the input units in addition to the input unit 50A and the input unit 50B. Specifically, as shown in FIG. 4, in the operation panel 40, the intermediate input unit 51X is disposed between the input unit 50A and the input unit 50B, and is also disposed between the input unit 50D and the input unit 50E. . That is, the intermediate electrode 46X of the intermediate input unit 51X disposed between the input unit 50A and the input unit 50B, the intermediate electrode 46X of the intermediate input unit 51X disposed between the input unit 50D and the input unit 50E, Are integral and electrically connected.

  Moreover, the operation panel 40 arranges the intermediate input unit 51Y between the input unit 50B and the input unit 50C and between the input unit 50E and the input unit 50F. Further, the intermediate input unit 51Z is disposed between the input unit 50A and the input unit 50D, between the input unit 50B and the input unit 50E, and between the input unit 50C and the input unit 50F. The intermediate input unit 51Y and the intermediate input unit 51Z have the same configuration as the intermediate input unit 51X.

  For convenience of explanation, when the intermediate input units 51X, 51Y, and 51Z are not specified, they are simply referred to as “intermediate input unit 51”. The intermediate input unit 51 is an example of a first intermediate input unit, a second intermediate input unit, a third intermediate input unit, a fourth intermediate input unit, and a fifth intermediate input unit. If the intermediate input surface and the intermediate electrode included in the intermediate input unit 51 are not specified individually, they are referred to as “intermediate input surface 48” and “intermediate electrode 46”, respectively. The intermediate input surface 48 is an example of a first intermediate surface, a second intermediate surface, a third intermediate surface, a fourth intermediate surface, and a fifth intermediate surface. The intermediate electrode 46 is an example of a first intermediate electrode, a second intermediate electrode, a third intermediate electrode, a fourth intermediate electrode, and a fifth intermediate electrode.

  In addition, the operation panel 40 includes an input control unit 60 that controls input to the input unit 50 and the intermediate input unit 51, as shown in FIG. The input control unit 60 includes electrodes 43A, 43B, 43C, 43D, 43E, and 43F included in the input units 50A, 50B, 50C, 50D, 50E, and 50F, and intermediate electrodes 46X, 46Y, and 46Z included in the intermediate input units 51. It detects the change in the output value from each electrode. The input control unit 60 corresponds to an IC (Integrated Circuit) for a capacitance type switch.

  In FIG. 4, the intermediate electrode 46X of the intermediate input portion 51X and the intermediate electrode 46Z of the intermediate input portion 51Z are overlapped, but at the overlapping position, the intermediate electrode 46X and the intermediate electrode 46Z The positions of the directions are different, and the two are not electrically connected. The positional relationship between the intermediate electrode 46Y and the intermediate electrode 46Z is the same.

  Next, an electrical configuration of the MFP 100 according to the present embodiment will be described. As shown in FIG. 5, the MFP 100 of this embodiment includes a controller 30 having a CPU 31, a ROM 32, a RAM 33, and an NVRAM (Non Volatile RAM) 34. The MFP 100 includes an image forming unit 1, an image reading unit 2, an operation panel 40, and a communication interface 37, which are controlled by the CPU 31. Note that the controller 30 in FIG. 5 is a collective term for the hardware used to control the MFP 100, such as the CPU 31, and does not necessarily represent a single piece of hardware that actually exists in the MFP 100.

  The ROM 32 stores firmware, which is a control program for controlling the MFP 100, various settings, initial values, and the like. The RAM 33 is used as a work area from which various control programs are read or as a storage area for temporarily storing image data. The NVRAM 34 is also used as a storage area for storing various information used in the MFP 100.

  The CPU 31 controls each component of the MFP 100 while storing the processing result in the RAM 33 or the NVRAM 34 according to a control program read from the ROM 32 and signals sent from various sensors.

  The communication interface 37 is hardware that enables communication with an external device. Specific examples of the communication interface 37 include a wired LAN interface, a wireless LAN interface, and a serial communication interface. Further, it may be a telephone line interface for enabling facsimile communication.

  The MFP 100 can transmit image data of a document read by the image reading unit 2 to an external device via the communication interface 37. Further, the MFP 100 receives a print job that causes the image forming unit 1 to form an image, a reading job that causes the image reading unit 2 to read an image, or a copy job that performs both from the external device via the communication interface 37. it can.

  The operation panel 40 is hardware that allows a message and various settings to be displayed and various information from the user to be input, and is provided on the exterior of the MFP 100 as shown in FIG. As described above, the operation panel 40 includes the display unit 41, the input unit 50, the intermediate input unit 51, and the input control unit 60. The input control unit 60 is an example of a control unit. Note that the CPU 31 or the controller 30 may be an example of a control unit.

[Operation panel overview]
Next, an operation when the operation panel 40 detects an input with the input unit 50 will be described. In particular, an operation when a plurality of input units 50 detect inputs simultaneously will be described.

  FIG. 6 shows a state in which the user's finger 91 is in contact with the input surface 45B of the input unit 50B, and the user's finger 92 is in contact with the input surface 45C of the input unit 50C. In this state, it can be estimated that the two fingers 91 and 92 are in contact with the input surface 45B and the input surface 45C of the cover 49, respectively, and the user has performed simultaneous input.

  In this case, the capacitances of the input unit 50B and the input unit 50C change, and the output values of the electrodes 43B and 43C change. On the other hand, since the user's fingers 91 and 92 are not in contact with the input surface 45A of the input unit 50A and the intermediate input surfaces 48X and 48Y of the intermediate input units 51X and 51Y, the capacitance does not change, and the electrodes 43A, The output values of the intermediate electrode 46X and the intermediate electrode 46Y do not change. Or even if it changes, the amount of change is small. Therefore, the input control unit 60 electrically connected to each electrode can determine that there has been simultaneous input to the input unit 50B and the input unit 50C.

  On the other hand, FIG. 7 shows a state in which the user's finger 91 makes contact with each of the input surface 45B of the input unit 50B, the intermediate input surface 48Y of the intermediate input unit 51Y, and the input surface 45C of the input unit 50C. . In this state, one finger 91 is in contact with the input surface 45B, the intermediate input surface 48Y and the input surface 45C of the cover 49, that is, one finger 91 is in contact with the input surface 45 or the intermediate input unit of the input unit 50. 51, the user is in contact across the intermediate input surface 48 and cannot guess whether the user has input to the input unit 50B or input to the input unit 50C. At least in this case, the user does not perform simultaneous input.

  In this case, as in the case of FIG. 6, the capacitances of the input unit 50B and the input unit 50C change and the output values of the electrodes 43B and 43C change. However, unlike the case of FIG. The capacitance of the intermediate input unit 51Y also changes, and the output value of the intermediate electrode 46Y also changes. Therefore, in MFP 100 of the present embodiment, when input control unit 60 that acquires output values from electrode 43 and intermediate electrode 46 detects simultaneous input at adjacent input units 50, intermediate input unit 51 positioned therebetween. It is judged whether there was simultaneous input by the presence or absence of input to.

[Signal output processing]
Next, a signal output processing procedure for realizing the above-described input determination on the operation panel 40 in the MFP 100 will be described with reference to a flowchart of FIG. The signal output processing is executed by the input control unit 60 at predetermined intervals such as 100 ms intervals.

  In the signal output process, the input control unit 60 first executes an input determination process for determining the presence / absence of input from each input unit 50 and each intermediate input unit 51 (S101). Details of the input determination process will be described with reference to the flowchart of FIG.

  In the input determination process, the input control unit 60 first acquires a detection value that is a value obtained by amplifying the output value from the electrode 43A in the input unit 50A (S201). In the input determination process, the input control unit 60 acquires a threshold value for determining whether or not there is an input to the input unit 50A (S202). S201 and S202 may be in reverse order or simultaneously. Note that an amplification factor and a threshold for amplifying an output value from the electrode 43 in the input unit 50 are stored in the input control unit 60 in advance.

  After S202, the input control unit 60 determines whether or not the detection value acquired in S201 is larger than the threshold acquired in S202 (S203). S203 is an example of a first input determination process, a second input determination process, and a third input determination process. In this embodiment, when the object is in contact with the input surface 45A of the input unit 50, the output value from the electrode 43A is larger than when the object is not in contact. Therefore, when the detected value is larger than the threshold value (S203: YES), the input control unit 60 determines that there is an input in the input unit 50A (S204), and when the detected value is not larger than the threshold value (S203: NO), it is determined that there is no input in the input unit 50A (S205).

  After S204 or S205, the input control unit 60 determines whether there is an undetermined input unit 50 for which the presence / absence of input has not been determined (S206). When there is an undetermined input unit 50 (S206: YES), the process proceeds to S201, and the input control unit 60 determines whether there is an input for one of the undetermined input units 50. The determination of the input of the input unit 50 may be performed from any input unit 50, or may be performed simultaneously for a plurality of input units 50. The threshold for each input unit 50 may be different for each input unit 50 or may be the same. In this embodiment, one common threshold value is used.

  When there is no undetermined input unit 50 (S206: NO), the input control unit 60 acquires an intermediate detection value that is an amplified value of the output value from the intermediate electrode 46X in the intermediate input unit 51X (S221). The amplification factor of the output value of the intermediate input unit 51 is different from the amplification factor of the output value of the input unit 50. Since the MFP 100 uses the air layer 47 between the cover 49 of the intermediate input unit 51 and the intermediate electrode 46, the output value when the user's finger contacts the intermediate input surface 48X is compared with the input unit 50. Small. Further, since the intermediate input unit 51 is used for detecting an erroneous input, it is desirable that the intermediate input unit 51 has high sensitivity. Therefore, the output ratio of the intermediate input unit 51 is made larger than the output ratio of the input unit 50. The output ratio is the ratio of the detected value to the output value. The amplification factor of the output value of the intermediate input unit 51 is also stored in the input control unit 60 in advance.

  In the input determination process, the input control unit 60 acquires an intermediate threshold value for determining whether or not there is an input to the intermediate input unit 51X (S222). S221 and S222 may be in reverse order or simultaneously. The intermediate threshold value is also stored in the input control unit 60 in advance.

  After S222, the input control unit 60 determines whether or not the intermediate detection value acquired in S221 is larger than the intermediate threshold acquired in S222 (S223). S223 is an example of a first intermediate input determination process, a second intermediate input determination process, a third intermediate input determination process, and a fourth intermediate input determination process. Even in the intermediate input unit 51X, when the object is in contact with the intermediate input surface 48X, the output value from the intermediate electrode 46X is larger than when the object is not in contact. Therefore, if the intermediate detection value is greater than the intermediate threshold value (S223: YES), the input control unit 60 determines that there is an input to the intermediate input unit 51X (S224), and the intermediate detection value is not greater than the intermediate threshold value. In this case (S203: NO), it is determined that there is no input in the intermediate input unit 51X (S225).

  After S224 or S225, the input control unit 60 determines whether there is an undetermined intermediate input unit 51 in which the presence / absence of input is not determined (S226). When there is an undetermined intermediate input unit 51 (S226: YES), the process proceeds to S221, and the input control unit 60 determines whether or not there is an input for one of the undetermined intermediate input units 51. Note that the input of the intermediate input unit 51 may be determined from any of the intermediate input units 51, or the presence / absence of inputs from a plurality of intermediate input units 51 may be determined simultaneously. Further, the intermediate threshold value for each intermediate input unit 51 may be different for each intermediate input unit 51 or may be the same. In this embodiment, one common intermediate threshold is used. Further, the threshold value of the input unit 50 and the intermediate threshold value of the intermediate input unit 51 may be the same or different.

  If there is no undetermined intermediate input unit 51 (S226: NO), the input control unit 60 ends the input determination process and returns to the signal output process. Thereby, the input control unit 60 grasps the presence / absence of input from each input unit 50 and each intermediate input unit 51. Note that the determination regarding the input unit 50 (S201 to S206) and the determination regarding the intermediate input unit 51 (S221 to S226) may be in reverse order or at the same time.

  Returning to the description of FIG. 8, after S101, the input control unit 60 determines whether or not there is an input unit 50 that is determined to have an input (S102). If there is no input unit 50 that is determined to have an input (S102: NO), the input control unit 60 ends the signal output process. A signal indicating that there is no input to the input unit 50 may be output. A signal output from the input control unit 60 is input to the controller 30 or the CPU 31 and used for various controls of the MFP 100.

  When there is even one input unit 50 that is determined to have an input (S102: YES), the input control unit 60 determines whether there is a combination in which there is an input in the adjacent input units 50 (S111). ).

  When there is no combination in which there is an input in the adjacent input units 50 (S111: NO), that is, when there is one input unit 50 with inputs, or even when there are a plurality of input units 50 with inputs, they are adjacent to each other. If not, the input control unit 60 determines whether there is an intermediate input unit 51 that is determined to have an input among the intermediate input units 51 adjacent to the input unit 50 that has an input (S112). Referring to FIG. 4, for example, if the input unit 50 having an input is the input unit 50A, the intermediate input units 51X and 51Z become the adjacent intermediate input units 51. If the input unit 50 having an input is the input unit 50B, the intermediate input units 51X, 51Y, and 51Z become the adjacent intermediate input unit 51.

  When there is no intermediate input unit 51 that is determined to have an input among the intermediate input units 51 that are adjacent to the input unit 50 that has an input (S112: NO), the object contacts only the input surface 45 of the input unit 50. Therefore, it can be assumed that accurate input has been made. Therefore, the input control unit 60 outputs a first input signal that is a signal indicating that there is an input for the input unit 50 that has been determined to have an input (S113). S113 executed when NO is obtained in S112 is an example of the first input signal output process. After S113, the signal output process is terminated.

  When there is an intermediate input unit 51 that is determined to have an input among the intermediate input units 51 that are adjacent to the input unit 50 that has an input (S112: YES), the object is intermediate in addition to the input surface 45 of the input unit 50 There is a high possibility that an accurate input is not performed because it protrudes and contacts the intermediate input surface 48 of the input unit 51. Therefore, the input control unit 60 invalidates the input (S151). A signal indicating that there is no input to the input unit 50 or a signal indicating that the input to the input unit 50 is invalid may be output. The procedure of not executing S113 when S112 is YES is an example of a first input signal output process. After S151, the signal output process is terminated.

  When there is a combination in which there is an input in the adjacent input units 50 (S111: YES), the input control unit 60 determines that the adjacent input units 50 are in the first direction, that is, the direction from the front to the back of the operation panel 40 for the user. It is determined whether or not they are adjacent to each other (S121).

  When performing simultaneous input in the first direction, as shown in FIG. 10, the user must place two fingers on the front and back, and accurate input to each input unit 50 is difficult. Therefore, erroneous input such as contact with the intermediate input surface 48 of the intermediate input unit 51 is likely to occur. On the other hand, when performing simultaneous input in the second direction, as shown in FIG. 11, the user can place two fingers apart left and right, and accurate input to each input unit 50 is expected. it can. In other words, since the ease of input varies depending on the direction of the combination of simultaneous inputs, it is preferable that the determination of the simultaneous input of the combination in the second direction is performed more strictly than the combination in the first direction.

  Therefore, when the direction is not the first direction (S121: NO), the input direction is the second direction, so the input control unit 60 applies the same processing as when the input units 50 are not adjacent to each other. That is, the input control unit 60 determines whether or not there is an intermediate input unit 51 that is determined to have an input among the intermediate input units 51 adjacent to the input unit 50 that has an input (S122).

  When there is no intermediate input unit 51 that is determined to have an input among the intermediate input units 51 adjacent to the input unit 50 that has an input (S122: NO), the input control unit 60 is determined to have an input. A simultaneous input signal that is a signal indicating that there is simultaneous input to the two input units 50 is output (S123). S123 executed when NO is obtained in S122 is an example of the second simultaneous input signal output process. After S123, the signal output process is terminated.

  When there is an intermediate input unit 51 that is determined to have an input among the intermediate input units 51 that are adjacent to the input unit 50 that has an input (S122: YES), there is a possibility that the input unit 50 is not correctly input. high. Therefore, the input control unit 60 invalidates the input (S151). The procedure in which S123 is not executed when YES is obtained in S122 is an example of a second simultaneous input signal output process. After S151, the signal output process is terminated.

  On the other hand, when the direction is the first direction (S121: YES), the input control unit 60 determines whether or not there is an input in the intermediate input unit 51 located between the adjacent input units 50 determined to have an input. Is determined (S131).

  When there is no input in the intermediate input unit 51 located between the adjacent input units 50 (S131: NO), it can be considered that two fingers are separated and input between the adjacent input units 50. That is, it can be considered that the user desires simultaneous input. On the other hand, even if the fingers are separated between the adjacent input units 50, there is a possibility that the intermediate input surface 48 of the intermediate input unit on the opposite side in the first direction may come into contact therewith. Therefore, the input control unit 60 invalidates the input of the intermediate input unit 51 adjacent in the first direction to the adjacent input unit 50 determined to have an input (S132). S132 is an example of invalidation processing. After S132, a simultaneous input signal is output (S123). After S123, the signal output process is terminated.

  Referring to FIG. 4, for example, if the adjacent input units 50 are the input units 50A and 50B, the intermediate input unit 51 located between the adjacent input units 50A and 50B is the intermediate input unit 51X, and is adjacent. The intermediate input unit 51 adjacent to the input units 50A and 50B in the first direction becomes the intermediate input unit 51Y. For example, if the adjacent input units 50 are the input units 50E and 50F, the intermediate input unit 51 located between the adjacent input units 50E and 50F is the intermediate input unit 51Y, and the adjacent input units 50E and 50F. The intermediate input unit 51 adjacent to the first direction becomes the intermediate input unit 51X. In S132, only the intermediate input unit 51 adjacent in the first direction is disabled, but the intermediate input unit 51 adjacent in the second direction may also be disabled.

  When there is an input in the intermediate input unit 51 located between the adjacent input units 50 (S131: YES), the input control unit 60 determines that there are two inputs determined in S111 that are input in the adjacent input units 50. It is determined whether or not both detection values of the input unit 50 are larger than the intermediate detection value of the intermediate input unit 51 located between the two input units 50 determined to have input in S131 (S141). . S141 is an example of a detection value determination process.

  When the detection values of the two input units 50 are both larger than the intermediate detection value of the intermediate input unit 51 located between the two input units 50 (S141: YES), the input surface 45 of the two input units 50 The user's finger is in contact with each other, a part of the finger is protruding and in contact with the intermediate input surface 48 of the intermediate input unit 51, and the intermediate detection value may be lower than the detection values of the two input units. Is expensive. That is, it can be considered that the user desires simultaneous input. Therefore, the input control unit 60 invalidates the input of the intermediate input unit 51 adjacent in the first direction to the adjacent input unit 50 determined to have an input (S132), and outputs a simultaneous input signal (S123). . S123 executed when YES is obtained in S141 is an example of the first simultaneous input signal output process. After S123, the signal output process is terminated.

  On the other hand, when at least one of the detection values of the two input units 50 is not larger than the intermediate detection value of the intermediate input unit 51 located between the two input units 50 (S141: NO), the user's finger is adjacent. There is a high possibility that the input unit 50 and the intermediate input unit 51 are in contact with each other, and therefore, the detection value at the intermediate input unit 51 which is the center of the three input units is the highest. There is a high possibility. That is, it is unlikely that the user wants simultaneous input. For this reason, the input control unit 60 invalidates the input instead of simultaneous input (S151). The procedure of not executing S123 when NO in S141 is an example of a first simultaneous input signal output process. After S151, the signal output process is terminated.

  As described above in detail, in the operation panel 40 of the MFP 100, when there is an input to all of the adjacent input units 50 and the intermediate input unit 51 located in the middle thereof, Each detection value is compared with the intermediate detection value of the intermediate input unit 51 located in the middle thereof. When the detected values of the two input units 50 are both larger than the detected value of the intermediate input unit 51, the input control unit 60 outputs a simultaneous input signal. On the other hand, when the intermediate detection value of the intermediate input unit 51 is larger, the input control unit 60 does not perform simultaneous input and does not output a simultaneous input signal. That is, the operation panel 40 of the MFP 100 compares the detected values when the adjacent input units 50 and the intermediate input unit 51 located between them detect an input of an object, thereby simultaneously inputting the detected values. The presence or absence of can be suitably determined.

Therefore, the present invention can naturally be improved and modified in various ways without departing from the gist thereof. For example, the input device to which the present invention is applied is not limited to the operation panel included in the image processing apparatus, but can be applied as long as it includes an input device such as an operation panel.

  In the embodiment, the intermediate input unit 51 and the input unit 50 have different configurations depending on whether the air layer 47 or the lens 44 is used, but may have the same configuration. For example, the intermediate input unit 51 may include the same lens as the input unit 50 and may include an air layer in a slight gap between the intermediate input unit 51 and the input unit 50. Further, for example, the intermediate input unit 51 may include a lens made of a material having a dielectric constant lower than that of the input unit 50.

  In the embodiment, the intermediate input unit 51 is disposed between both the input unit 50 adjacent in the first direction and the input unit 50 adjacent in the second direction. It may be only. Further, in the embodiment, the intermediate input unit 51 between the input units 50 adjacent in the first direction and the intermediate input unit 51 between the input units 50 adjacent in the second direction are separate bodies. The intermediate input unit 51 may be connected and integrated.

  In the embodiment, the direction from the front to the back of the operation panel 40 is the first direction, but the present invention is not limited to this.
