Hereinafter, the display input device according to the present embodiment of the present invention will be described by taking as an example a multi-function peripheral equipped with a plurality of functions such as a printer function, a copy function, and a transmission function (fax function).

<Overall configuration of MFP>
As shown in FIG. 1, the multifunction peripheral 100 (corresponding to a “display input device”) includes an image reading unit 1 and a printing unit 2. The image reading unit 1 reads a document and generates image data. The printing unit 2 transports the paper along the paper transport path 21 and forms a toner image based on the image data. Then, the printing unit 2 prints the toner image on the paper being conveyed, and discharges the printed paper to the discharge tray 22.

The printing unit 2 includes a paper feed unit 3, a paper transport unit 4, an image forming unit 5, and a fixing unit 6. The paper feed unit 3 includes a pickup roller 31 and a paper feed roller pair 32, and supplies the paper stored in the paper cassette 33 to the paper transport path 21. The paper transport unit 4 includes a plurality of transport roller pairs 41 and transports the paper along the paper transport path 21.

The image forming unit 5 includes a photosensitive drum 51, a charging device 52, an exposure device 53, a developing device 54, a transfer roller 55, and a cleaning device 56. The image forming unit 5 forms a toner image based on the image data, and transfers the toner image to a sheet. The fixing unit 6 includes a heating roller 61 and a pressure roller 62, and fixes the toner image transferred onto the sheet by heating and pressing.

Here, the multifunction device 100 is provided with an operation display unit 7 for performing various settings. The operation display unit 7 is disposed, for example, on the front side of the multi-function device 100 (location indicated by a broken line in FIG. 1).

<Operation panel configuration>
As shown in FIG. 2, the operation display unit 7 is an abbreviation whose longitudinal direction is the left-right direction as viewed from the user who uses the multifunction machine 100 (as viewed from the normal direction of the operation surface OS and the display surface DS described later). It has a rectangular planar shape. Hereinafter, the longitudinal direction of the operation display unit 7 in plan view is referred to as an LD direction.

In addition, the operation display unit 7 includes a touch panel display 71. The touch panel display 71 includes a touch panel unit 72 and a display unit 73. The touch panel unit 72 and the display unit 73 are disposed in a resin casing 70 that forms an outline of the operation display unit 7. The housing 70 is formed with a display opening DO for exposing a portion of the operation surface OS described later that overlaps the display surface DS.

The touch panel unit 72 has an operation surface OS for accepting various input operations from the user. The input operation refers to an operation (touch operation) in which an operating body such as a finger or a touch pen is brought into contact with the operation surface OS. And touch panel part 72 will output the value which shows the position (coordinate) which the operation body contacted as operation information, if input operation is received.

The display unit 73 is a display panel such as a liquid crystal display panel (including a backlight) or an organic EL display panel. The display unit 73 is disposed on the side opposite to the operation surface OS side (the lower side of the touch panel unit 72). That is, the display unit 73 is covered with the touch panel unit 72. The display unit 73 displays an operation reception screen (not shown) for receiving various input operations on the display surface DS. For example, various soft keys and messages are arranged in the operation reception screen.

The control of the operation display unit 7 is performed by a control unit 110 (see FIG. 1) provided in the multifunction machine 100. Note that a main control unit for performing overall control of the multifunction peripheral 100 may be configured to control the operation display unit 7, and an operation display control unit for performing control of the operation display unit 7 is controlled by the main control unit. You may provide separately from a part.

For example, the control unit 110 causes the display unit 73 to display an operation reception screen. Then, when a touch operation on the soft key in the operation reception screen is performed via the touch panel unit 72 (when the operating body contacts the operation surface OS), the control unit 110 outputs a value output as operation information from the touch panel unit 73. Based on (a value indicating the contact position of the operating body), the soft key that received the touch operation is detected. In addition, when detecting a soft key that has received a touch operation, the control unit 110 causes the display unit 73 to display a screen associated with the soft key. That is, the control unit 110 executes processing assigned to the soft key that has received the touch operation.

In addition, the operation display unit 7 includes a plurality of hard keys 74. The plurality of hard keys 74 are pushed into the housing 70 when pressed by the user. For example, the operation panel 7 includes a plurality of hard keys 74 for receiving various instructions such as a job execution start instruction, a job execution stop instruction, an input setting value reset instruction, and a function selection instruction to be used. Is provided. A numeric keypad (character key) for inputting numbers (characters representing numbers), symbols, and the like is also provided as a hard key 74 on the operation display unit 7.

The plurality of hard keys 74 are arranged in a predetermined area other than the display part arrangement area DA (formation area of the display opening DO), which is an area in which the display part 73 is arranged in a plan view. For example, the display unit arrangement area DA is a substantially central area in the LD direction. Each area of the one area KA1 outside the LD direction with respect to the display area DA and the other area KA2 on the opposite side of the one area KA1 across the display area DA is a hard key. 74 arrangement regions. In other words, a pair of areas adjacent to the display unit arrangement area DA in the LD direction (areas on both sides of the display unit arrangement area DA) are the arrangement areas of the hard keys 74, respectively.

Here, detection of whether or not the hard key 74 has been pressed (which of the plurality of hard keys 74 has been pressed) is performed based on the output value of the touch panel unit 72. Details will be described below with reference to FIGS.

In the following description, the one area KA1 and the other area KA2 may be referred to as key arrangement areas KA1 and KA2, respectively. Further, the key arrangement areas KA1 and KA2 may be collectively referred to as a key arrangement area KA. 3 to 8 referred to in the following description schematically show the configuration of the operation display unit 7, and do not show actual dimensions and shapes as they are.

First, as shown in FIG. 3, the touch panel display 71 is connected to a control board 75 for controlling the operation of the touch panel unit 72 and the display unit 73. The touch panel display 71 and the control board 75 are connected via a flexible flat cable 76 or the like. The control board 75 is connected to the control unit 110 (see FIG. 1). For example, an output value (operation information) of the touch panel unit 72 that is output when the operating body comes into contact with the operation surface OS is transmitted to the control unit 110 via the control board 75.

Further, as shown in FIG. 4, the touch panel portion 72 is formed so that the operation surface OS has a substantially rectangular shape in plan view. Further, the display unit 73 (indicated by a dotted line in FIG. 4) is also formed so that the shape of the display surface DS in a plan view is substantially rectangular. However, the planar size of the touch panel unit 72 is larger than the planar size of the display unit 73. For this reason, when the touch panel part 72 and the display part 73 are arranged so as to overlap each other, a part of the touch panel part 72 protrudes outside the display part arrangement area DA (area where the display part 73 is arranged). The portion of the touch panel portion 72 that protrudes outside is a portion that does not overlap the display portion 73. Accordingly, the operation surface OS includes an overlapping portion OP that overlaps the display surface DS and a non-overlapping portion NP that does not overlap the display surface DS.

For example, the touch panel unit 72 extends from the display unit arrangement area DA to each of the key arrangement areas KA1 and KA2. In this case, the operation surface OS has non-overlapping portions NP in the key arrangement areas KA1 and KA2. That is, the hard key 74 is arranged in an area corresponding to the non-overlapping portion NP. In FIG. 4, the hard keys 74 arranged in the key arrangement area KA are indicated by a one-dot chain line.

Here, as shown in FIG. 3, there is no switch member such as a tactile switch that is turned on and off by being pressed by the hard key 74 below the hard key 74 (in the direction in which the hard key 74 is pressed). . For this reason, the hard key 74 and the operation surface OS (non-overlapping portion NP) are arranged to face each other with a space therebetween.

The operation display unit 7 is provided with a plurality of hard keys 74, and all of the plurality of hard keys 74 are arranged to face the operation surface OS (non-overlapping portion NP) with a space therebetween.

Although not shown, for example, the hard key 74 is urged upward (in a direction away from the operation surface OS) by the urging member. Thus, the hard key 74 is held at a predetermined position separated from the operation surface OS when not pressed. When the hard key 74 is pressed, the hard key 74 is pushed into the housing 70. That is, the hard key 74 moves downward (in the direction approaching the operation surface OS) against the urging force of the urging member. In order to prevent the hard key 74 from falling off the housing 70, a holding portion that holds the hard key 74 in a predetermined position (for example, an engaging portion that engages the hard key 74 in the predetermined position) is provided in the housing 70. Provided.

As a result, as shown in FIG. 5, when the hard key 74 is not pressed, an interval is generated between the hard key 74 and the operation surface OS (see the upper diagram of FIG. 5). That is, an input operation is not performed on the non-overlapping portion NP of the operation surface OS.

When the hard key 74 is pressed from this state, the hard key 74 is pushed toward the non-overlapping portion NP of the operation surface OS, and as a result, the hard key 74 enters the non-overlapping portion NP of the operation surface OS. Contact (see the lower figure of FIG. 5). That is, an input operation is performed on the non-overlapping portion NP of the operation surface OS.

When the hard key 74 touches the non-overlapping portion NP of the operation surface OS, the touch panel unit 72 touches the hard key 74 in the same manner as when the operating body (such as a finger or a touch pen) contacts the overlapping portion OP of the operation surface OS. A value indicating the position is output as operation information. Further, based on the output value (operation information) of the touch panel unit 72, the control unit 110 (see FIG. 1) detects the pressed hard key 74. That is, the touch panel unit 72 functions as a detection member for detecting whether or not the hard key 74 is pressed (which of the plurality of hard keys 74 is pressed). In other words, an area facing the hard key 74 in the non-overlapping portion NP of the operation surface OS functions as an area for receiving an instruction to execute a process assigned to the hard key 74. Therefore, it is not necessary to install a switch member such as a tactile switch (the touch panel unit 72 can be used instead of the switch member).

For example, when the hard key 74 is pressed, the tip of the hard key 74 directly contacts the operation surface OS of the touch panel unit 72 (see FIG. 5). Alternatively, as illustrated in FIG. 6, a sheet member 8 (for example, a resin sheet) may be disposed between the tip portion of the hard key 74 and the operation surface OS of the touch panel unit 72. In this case, when the hard key 74 is pressed, the front end portion of the hard key 74 and the operation surface OS of the touch panel unit 72 come into contact with each other via the sheet member 8. That is, the hard key 74 indirectly contacts the operation surface OS. For example, the sheet member 8 is affixed to the inner surface of the housing 70 (the surface facing the operation surface OS). When such a sheet member 8 is arranged between the hard key 74 and the touch panel portion 72, it is possible to suppress the operation surface OS from being damaged.

Although not shown, one sheet member 76 may be commonly used for a plurality of hard keys 74. For example, the sheet member 76 may be attached to the entire inner surface of the housing 70 (however, a portion corresponding to the display opening DO is opened). Or you may affix the sheet | seat member 76 to each front-end | tip part of the some hard key 74 separately.

When the control unit 110 detects the hard key 74 pressed by the user, the control unit 110 executes processing assigned to the hard key 74. For example, if the pressed hard key 74 is a start key, the control unit 110 starts execution of the job, and if the pressed hard key 74 is a stop key, the control unit 110 stops the job being executed. When the hard key 74 pressed by the user is a numeric keypad (when the numeric keypad 74 touches the operation surface OS), the control unit 110 detects the character assigned to the pressed numeric keypad as an input character, and The detected input character is displayed on the display unit 73.

Here, as shown in FIGS. 7 and 8, the casing 70 of the operation display unit 7 includes a first casing 701 and a second casing 702. The first housing 701 is a main body housing for holding the touch panel unit 72 and the display unit 73 that form the touch panel display 71, and is attached to the apparatus main body of the multifunction peripheral 100. Note that the first housing 701 may be detachable from the main body of the multifunction peripheral 100. That is, the operation display unit 7 may be detachable from the main body of the multi-function device 100.

The second casing 702 is a casing having a display opening DO. The hard key 74 is held in the second housing 702. The second housing 702 is detachable from the first housing 701. For example, the first housing 701 holds the second housing 702 so as to be slidable. Although not particularly limited, a rail-like protrusion 711 extending in a direction orthogonal to the longitudinal direction (LD direction) in plan view of the operation display unit 7 is provided on the outer surface of the first housing 701. A groove portion 712 extending in a direction orthogonal to the LD direction is provided on the inner surface of the second housing 702 (the surface facing the outer surface of the first housing 701).

The mounting of the second housing 702 to the first housing 701 can be performed by fitting the groove 712 into the projecting portion 711 and sliding the second housing 702 in the A direction (one direction) toward the apparatus main body in this state. For example, although not shown, the first housing 701 and the second housing 702 have a first engagement portion and a second engagement portion, respectively. Then, the second housing 702 is slid in the A direction with respect to the first housing 701, and the positional relationship between the touch panel display 71 and the hard keys 74 in a plan view is in the state shown in FIG. 2 (second housing 702). Is mounted at a standard mounting position, which is one of the predetermined mounting positions), the first engaging portion and the second engaging portion engage with each other. Thereby, it is possible to suppress the second housing 702 from falling off from the first housing 701. When removing the second housing 702 from the first housing 701, the second housing 702 is separated from the apparatus main body in the B direction in a state where the engagement between the first engaging portion and the second engaging portion is released. Slide in the other direction.

For example, the first casing 701 is provided with a mounting detection unit for detecting that the second casing 702 is mounted (the second casing 702 is at a predetermined mounting position). Although not particularly limited, the attachment detection unit includes a transmission type optical sensor having a light emitting unit and a light receiving unit, and an actuator to be detected by the optical sensor. The actuator is pivotally attached. And when the 2nd housing | casing 702 is not in a predetermined mounting position, an actuator open | releases or shields the detection area | region (optical path between a light emission part and a light-receiving part) of an optical sensor. On the other hand, when the second housing 702 is slid relative to the first housing 701 and the second housing 702 reaches a predetermined mounting position, the actuator rotates by contacting the second housing 702, The detection area of the optical sensor is shielded or opened. As a result, the output value of the mounting detection unit (light sensor) changes depending on whether the second housing 702 is at the predetermined mounting position or not.

The output of the mounting detection unit is received by the control unit 110 (see FIG. 1). The control unit 110 determines whether the second housing 702 is at a predetermined mounting position based on the output value of the mounting detection unit (whether the second housing 702 is mounted on the first housing 701). ). When the second housing 702 changes from a state where it is not at the predetermined mounting position, the control unit 110 causes the touch panel unit 72 to receive an instruction to execute the process assigned to the hard key 74. In other words, the control unit 110 changes the area facing the hard key 74 in the operation surface OS to an area for receiving a process execution instruction assigned to the hard key 74. Hereinafter, an area of the operation surface OS that changes to an area for receiving an instruction to execute a process assigned to the hard key 74 may be referred to as a hard key corresponding area. Note that when the second housing 702 is not attached to the first housing 701, the control unit 110 invalidates the operation on the non-overlapping region NP of the operation surface OS.

Here, although not shown, when the second casing 702 is not attached to the first casing 701, a key image simulating the hard key 74 (an image showing a software key) is displayed on the display unit 73, and the key image is displayed. The touch operation (operation for touching one area of the touch panel unit 72 corresponding to the display area of the key image) may be accepted as an instruction to execute the process assigned to the hard key 74. That is, when a touch operation on a key image simulating the hard key 74 is performed, the process assigned to the hard key 74 may be executed.

In the case of such a configuration, for example, the operation surface OS and the display surface DS are overlapped in an area covered by the second housing 702 when the second housing 702 is attached to the first housing 701. That is, when the second casing 702 is attached to the first casing 701, the hard key corresponding area of the operation surface OS that is to face the hard key 74 (to receive an instruction to execute the process assigned to the hard key 74). Until the display surface DS and the display surface DS overlap, the plane size of the display unit 73 is increased. Then, when the second housing 702 is not attached to the first housing 701, a key image simulating the hard key 74 is displayed in an area overlapping the hard key corresponding area of the operation surface OS in the display surface DS.

Note that when the second casing 702 is not attached to the first casing 701, a plurality of key images respectively corresponding to the plurality of hard keys 74 provided in the second casing 702 may be displayed. Alternatively, only a key image corresponding to a predetermined hard key 74 among the plurality of hard keys 74 may be displayed. In addition, a key image for receiving an instruction to execute a process different from the process assigned to the hard key 74 may be displayed.

For example, there are a plurality of mounting positions (predetermined mounting positions) of the second casing 702 with respect to the first casing 701. One of the plurality of predetermined mounting positions is a standard mounting position, and the other predetermined mounting positions are set to positions shifted from the standard mounting position by a predetermined amount in the sliding direction (B direction) of the second housing 702. That is, when the second housing 702 is mounted at a predetermined mounting position other than the standard mounting position, the second housing 702 is displaced in the B direction with respect to the first housing 701. When the second housing 702 is mounted at any one of a plurality of predetermined mounting positions (including the standard mounting position), one area of the operation surface OS facing the hard key 72 at that time is a hard key. The area changes to an area for receiving an instruction to execute the process assigned to 72.

As described above, the operation display unit 7 of the multifunction peripheral 100 (display input device) of the present embodiment has the operation surface OS for accepting an input operation, and when the operation body comes into contact with the operation surface OS, the operation body 7 A touch panel unit 72 that outputs a value indicating the touch position as operation information, and a display unit that is disposed on the opposite side of the touch panel unit 72 from the operation surface OS side and has a display surface DS that displays a screen for receiving input operations 73 and a hard key 74 that is depressed by being depressed. The hard key 74 is disposed so as to face the operation surface OS, and comes into direct or indirect contact with the operation surface OS when pressed.

In the configuration of the present embodiment, when the hard key 74 is pressed, the pressed hard key 74 comes into contact with the operation surface OS, and thus the value (operation information) indicating the contact position of the pressed hard key 74 is a touch panel unit. 72. For this reason, the pressed hard key 74 can be detected based on the output value of the touch panel unit 72. Therefore, it is not necessary to provide a hard key board (switch board) on which a switch or the like is mounted. As a result, it is possible to suppress the configuration of the operation panel 7 from becoming complicated (leading to cost reduction).

Further, in the present embodiment, as described above, the one area KA1 located outside the display section arrangement area DA (the arrangement area of the display section 73) and the display section arrangement area DA are arranged on the opposite side to the one area KA1. A certain other area KA2 is an area where the hard keys 74 are arranged. The touch panel unit 72 extends from the display unit arrangement area DA to the one area KA1 and the other area KA2. That is, the touch panel portion 72 integrally includes portions (non-overlapping portions NP) respectively disposed in the one region KA1 and the other region KA2, and is not divided into a plurality of portions. If comprised in this way, it can be made the state arrange | positioned so that the hard key 74 may oppose the operation surface OS easily. That is, the pressed hard key 74 can be easily brought into contact with the operation surface OS.

Although not shown, a support member for supporting the non-overlapping portion NP of the touch panel portion 72 may be provided on the opposite side of the non-overlapping portion NP of the touch panel portion 72 from the operation surface OS side. If comprised in this way, when the non-overlapping part NP of the touch panel part 72 is pressed down by the hard key 74, it can suppress that the non-overlapping part NP of the touch panel part 72 deform | transforms largely.

Further, in the present embodiment, as described above, all of the plurality of hard keys 74 provided in the operation display unit 7 are arranged to face the operation surface OS. With this configuration, even in the configuration in which the operation display unit 7 is provided with a plurality of hard keys 74, it is not necessary to provide a hard key board (switch board) on which switches and the like are mounted.
