The angle (β−α) 1211a is an angle calculated based on the angle α detected by the sensor α171 and the angle β detected by the sensor β172 of the angle detection unit 17 shown in FIG. In the present embodiment, the angle β is the angle obtained by subtracting the angle α detected by the sensor α 171 from the angle β detected by the sensor β 172 of the angle detection unit 17 shown in FIG. 1, and as shown in FIG. The angle formed by the bottom surface of the document reading unit 40 and the touch panel 131 (operation surface) of the input device 10 in a state of being closed with respect to 30 is set.

  The correction amount D1211b is a numerical value for correcting the input detection area of the touch panel 131 of the input device 10 shown in FIG. 1 corresponding to the angle (β−α) 1211a. In this embodiment, the angle (β−α) 1211a is an angle in a range from −45 degrees to 135 degrees. For example, the numerical value ((+6) mm to (−2) of the correction amount D1211b for each degree. mm).

The numerical value which correct | amends the input detection area | region of the touch panel 131 corresponding to is stored.

In the present embodiment, the correction table 1211 has a larger value of the correction amount D1211b that moves the position of the input detection area of the touch panel 131 as the angle (β−α) 1211a moves away from the median with 90 ° as the median. It is comprised so that it may become.

As shown in FIG. 9A, the input detection area 111a of the “Yes” operation button coincides with the display area of the “Yes” operation button, and the input detection area before correction is the “No” operation button. The input detection area 111b matches the display area of the “No” operation button.

  As shown in FIG. 9B, the input detection area 111c of the “Yes” operation button holds the display area of the “Yes” operation button and the correction amount D, as shown in FIG. B is corrected so as to move downward in the rotation direction of the input device 10 indicated by B, and the input detection area 111d of the “No” operation button holds the display area of the “No” operation button and the correction amount D. Correction is made so as to move downward in the rotational direction of the input device 10 indicated by the middle arrow B.

  The correction amount D for correcting the position of the input detection area is the correction amount of the correction table 1211 shown in FIG. 7 based on the angle α detected by the sensor α 171 and the angle β detected by the sensor β 172 of the angle detection unit 17 shown in FIG. Determined by D1211b. At this time, when the correction amount D1211b is positive, the position of the input detection region is corrected in the + direction of the arrow B in FIGS. 8 and 9B, and when the correction amount D1211b is negative, FIGS. The position of the input detection area is corrected in the minus direction of the arrow B in FIG.

Although the corrected input detection area is not displayed on the LCD 111, it is detected that the operation button has been selected by detecting that the corrected input detection area is touched by the operator.
As described above, in this embodiment, the position of the input detection area of the touch panel 131 is determined based on the angle α detected by the sensor α171 of the angle detection unit 17 and the angle β detected by the sensor β172 shown in FIG. It correct | amends so that it may move to the downward direction or upward direction in the rotation direction of the input device 10 which the arrow B in 9 (b) shows.

The operation of the above configuration will be described.
First, an input detection area correction process performed by the input device will be described with reference to FIG. 1 according to a step indicated by S in the flowchart showing the flow of the input detection area correction process in the first embodiment of FIG. This input detection area correction process is started when the sensor α171 or the sensor β172 detects a change in the angle α or the angle β.

S101: The angle detection unit 17 of the input device 10 detects an angle α formed by the printing unit 30 and the document reading unit 40 by the sensor α171 according to an instruction from the panel processing control unit 14, and inputs the document reading unit 40 by the sensor β172. An angle β formed by the apparatus 10 is detected.
The panel processing control unit 14 compares the angle α or angle β detected by the angle detection unit 17 with the angle α or angle β detected by the previous processing, and sets the angle α or angle β detected by the angle detection unit 17. It is determined whether or not there is a change. If it is determined that there is a change, the process proceeds to S102, and if it is determined that there is no change, the process ends.

S102: The panel processing control unit 14 that has determined that the angle α or the angle β detected by the angle detection unit 17 has changed is based on the angle α detected by the sensor α171 of the angle detection unit 17 and the angle β detected by the sensor β172. The correction amount of the input detection area of the touch panel 131 is acquired.
Specifically, the panel processing control unit 14 subtracts the angle β from the angle α by the detection area correction unit 121 of the input information processing unit 12, and based on the obtained angle, the angle of the correction table 1211 shown in FIG. (Β−α) 1211a is searched, and the value of the correction amount D1211b corresponding to the obtained angle is acquired.

S103: The panel processing control unit 14 corrects the position of the input detection area of the LCD 111 (touch panel 131) of the input device 10 by the detection area correction unit 121 based on the acquired correction amount, and ends this process.
Next, an input detection process performed by the input device will be described with reference to FIG. 1 in accordance with a step represented by S in the flowchart showing the flow of the input detection process in the first embodiment of FIG.

S201: When the input receiving unit 13 of the input device 10 detects that the touch panel 131 is touched by an instruction from the panel processing control unit 14, the input receiving unit 13 acquires the X coordinate and the Y coordinate of the touched touch panel 131.
S202: The input reception unit 13 determines whether or not the acquired X coordinate and Y coordinate are within the input detection area after being corrected by the above-described input detection area correction processing. If the input receiving unit 13 determines that the acquired X coordinate and Y coordinate are within the input detection area, the process proceeds to S203.

S203: The input receiving unit 13 that has determined that the acquired X coordinate and Y coordinate are within the input detection region notifies the panel processing control unit 14 that an operation button corresponding to the input detection region has been touched. The panel processing control unit 14 performs processing according to the notified operation button, and ends this processing.
As shown in FIG. 12A, when the angle (β−α) is 90 degrees, when the operator touches the touch panel 131, the position where the operator tries to touch with the fingers and the touch panel 131 touches the fingers. The position for detecting is an area 81, which is substantially coincident. Therefore, the touch panel 131 can detect that an operator's finger touches the input detection area.

  On the other hand, as shown in FIG. 12B, when the angle (β−α) is 45 degrees or the like, when the operator touches the touch panel 131, the position where the touch panel 131 detects a finger contact is, for example, a region 82. Thus, a deviation from a position where the operator tries to touch with a finger occurs. This is because not the tip of the operator's finger but the abdomen touches the touch panel 131. For this reason, the touch panel 131 may not be able to detect that the operator's finger has touched the input detection area.

  In order to solve such a problem, as shown in FIG. 13, when the position of the input detection area is corrected based on the rotation angle γ with respect to the document reading unit 40 of the input device 10, FIG. As shown in FIG. 13B, the operator can touch the position of the desired input detection area, but the document reading unit 40 is rotated with respect to the printing unit 30 as shown in FIG. When the angle of the touch panel 131 of the input device 10 changes for the operator, it becomes difficult for the operator to touch the position of the desired input detection area.

  Therefore, in this embodiment, as shown in FIG. 14, the position of the input detection area of the touch panel 131 is determined based on the angle α detected by the sensor α 171 and the angle β detected by the sensor β 172 of FIG. By making correction so as to move downward or upward in the rotation direction of the input device 10 indicated by the arrow B in FIG. 9B, the rotation is performed with respect to the printing unit 30 and the document reading unit 40. The input detection area of the touch panel 131 of the movable input device 10 can be correctly touched, and the convenience for the user can be improved.

  As described above, in the first embodiment, the position of the input detection area of the input device is corrected according to the angle of the document reading unit with respect to the printing unit and the angle of the input device with respect to the document reading unit. The user can correctly touch the input detection area, and the convenience of the user can be improved.

  In the configuration of the second embodiment, a correction table for correcting the position of the input detection area according to the height of the input device is added to the configuration of the input device of the MFP of the first embodiment. The configuration of the second embodiment will be described based on the block diagram showing the configuration of the MFP in the second embodiment of FIG. Note that parts similar to those of the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.

  In FIG. 15, the detection area correction unit 121 corrects the position of the input detection area according to the correction table 1211 described in the first embodiment and the height of the input device 10 and the eye of the operator. A correction table 1212. Details of the height correction table 1212 will be described later.

As shown in FIG. 16, for example, even when the angle (β−α) is 90 degrees, the height of the input device 10 is higher as shown in FIG. 16B than in FIG. Since the abdomen may contact the touch panel 131 instead of the tip of the operator's finger, the touch panel 131 cannot detect the contact of the operator's finger in the input detection area. Sometimes.
Therefore, in this embodiment, the position of the input detection area is corrected according to the height of the input device 10.

FIG. 17 is an explanatory diagram of the height of the input device in the second embodiment.
In FIG. 17, the height hm of the touch panel 131 of the input device 10 is the height hb of the base on which the MFP 1 is placed, the height hp of the printing unit 30, and the height from the printing unit 30 of the touch panel 131 of the input device 10. The height is obtained by adding the height ht.
The height ht can be calculated from the length ls in the direction orthogonal to the rotation axis of the document reading unit 40 and the angle α, and can be calculated as length ls × sin α. In the present embodiment, the height ht is described as the height from the upper surface of the printing unit 30 to the rotation fulcrum of the input device 10, but the height of the central portion of the touch panel 131 of the input device 10 from the upper surface of the printing unit 30 is described. And so on.

  As shown in FIG. 18, when a height hs is provided as a space between the printing unit 30 and the document reading unit 40 of the MFP 1, the height hm of the touch panel 131 of the input device 10 is set to mount the MFP 1. The height hb of the table to be placed, the height hp of the printing unit 30, the height hs between the printing unit 30 and the document reading unit 40, and the height ht from the printing unit 30 of the touch panel 131 are added. Become height.

  Furthermore, in this embodiment, the height hb of the table on which the MFP 1 is placed, the height hp of the printing unit 30, the length ls in the direction perpendicular to the rotation axis of the document reading unit 40, and the eyes of the operator It is assumed that the height th is stored in advance in the storage unit. The height hb of the table on which the MFP 1 is placed, the height hp of the printing unit 30, the length ls in the direction perpendicular to the rotation axis of the document reading unit 40, and the eye height th are set by the operator. It is assumed that an input operation is accepted on the touch panel 131 of the input device 10 and set in the storage unit.

FIG. 19 is an explanatory diagram of a height correction table in the second embodiment.
In FIG. 19, a height correction table 1212 is information held by the detection area correction unit 121 shown in FIG. 15 and stored in the ROM 15 or the like, and includes a height (hm-th) 1212a and a correction amount E1212b. Has been.
The height (hm-th) 1212a is a height calculated based on the height th of the operator's eyes from the height hm shown in FIGS. In this embodiment, the height is obtained by subtracting the height th of the operator's eyes from the height hm shown in FIGS.

  The correction amount E1212b is a numerical value for correcting the input detection area of the touch panel 131 of the input device 10 shown in FIG. 15 corresponding to the height (hm-th) 1212a. In this embodiment, the height (hm-th) 1212a is assumed to be a height in the range from +50 cm to −50 cm. For example, the numerical value ((+2) mm to (−2) mm of the correction amount E1212b for each 1 cm. ).

As described above, the height correction table 1212 corrects the input detection area of the touch panel 131 in accordance with the height calculated based on the height th of the operator's eyes from the height hm shown in FIGS. 17 and 18. The numerical value to be remembered.
In this embodiment, the height correction table 1212 is input to the touch panel 131 as the absolute value of the height (hm−th) 1212a (the difference between the height hm and the height th of the operator's eyes) increases. The numerical value of the correction amount E1212b for moving the position of the detection region is configured to be large.

Further, the correction amount E1212b of the height correction table 1212 moves the position of the input detection area of the touch panel 131 downward when the height hm is higher than the eye height th of the operator, and the height hm Is lower than the eye height th of the operator, the position of the input detection area of the touch panel 131 is configured to move upward in the touch panel 131.
The sign of the numerical value of the correction amount E1212b indicates that the input detection area is moved below the touch panel 131 and minus above the touch panel 131, as shown in FIG. That is, the sign of the numerical value of the correction amount E1212b moves the input detection area to the printing unit 30 side of the touch panel 131 and minus to the opposite side of the printing unit 30 of the touch panel 131, as shown in FIG. It is shown that.

  In the present embodiment, as shown in FIG. 20A, when the height hm <the eye height th of the operator, the touch panel 131 is positioned below the eye height of the operator, so that the operator touches the touch panel. Operate to look down at 131. Therefore, the position of the input detection area of the touch panel 131 is corrected so as to move upward in the rotation direction of the input device 10 indicated by the arrow B in FIGS. 8 and 9B.

  As shown in FIG. 20B, when the height hm> the eye height th of the operator, the touch panel 131 is positioned above the eye height of the operator, so the operator looks up at the touch panel 131. Operate as follows. Therefore, the position of the input detection area of the touch panel 131 is corrected so as to move downward in the rotation direction of the input device 10 indicated by the arrow B in FIGS. 8 and 9B.
