  The transmission mode key 26 is a key for setting the operation mode of the MFP 1 to the transmission mode. The transmission mode means a mode in which the image reading apparatus 2 reads an image of a document and transmits the read document image to the outside. Note that the transmission mode includes a fax mode in which an image is transmitted to an external device by FAX, and an image transmission mode in which an image is transmitted to a terminal device connected to the MFP 1 via a network.

  The copy mode key 27 is a key for setting the operation mode of the MFP 1 to the copy mode. The copy mode means a mode in which the image reading apparatus 2 reads an image of a document and the printer 3 prints (copies) the image on paper.

  The job status key 28 is a key for displaying a job list image showing a list of unprocessed job files on the touch screen 30 for each of the various modes described above.

  Next, the touch screen 30 will be described. The touch screen 30 displays various images that prompt the user to input various commands in the MFP 1. When the user touches the touch screen 30, the various commands are input.

  As shown in FIG. 5, the touch screen 30 is configured by covering a touch panel 30b on a liquid crystal display panel 30a.

  The liquid crystal display panel 30a is a liquid crystal display having a dual view function. Therefore, as shown in FIG. 4, the touch screen 30 displays the first image from the screen in the first direction, and at the same time, differs from the first image in the second direction different from the first direction from the screen. It has a function of displaying the second image, that is, a function of simultaneously displaying two different images.

  The touch panel 30b is a capacitively coupled touch panel made of a transparent material that changes the surface charge when the user touches it.

  Next, the open / close panel 31 will be described. The open / close panel 31 is a cover member of the touch screen 30. As shown in FIG. 4, a hinge 33 is formed on one side of the opening / closing panel 31, and the hinge 33 is attached to the operation panel 5 in the vicinity of the touch screen 30.

  The open / close panel 31 is configured to be rotatable about a hinge 33 as a rotation axis. Further, when the user rotates the open / close panel 31, the open / close panel 31 covers the touch screen 30, and the open state where the touch screen 30 is exposed to the outside (the state shown in FIGS. 4 and 5). And can be switched.

  Further, as shown in FIGS. 4 and 5, a mirror 32 is formed on the open / close panel 31 on the surface on the touch screen 30 side. As shown in FIG. 5, the mirror 32 is covered with a touch panel 34. Similar to the touch panel 30b, the touch panel 34 is a capacitively coupled touch panel made of a transparent material that changes the surface charge when the user touches it.

  Then, as shown in FIG. 5, in the open state of the open / close panel 31, the mirror 32 enters the second image displayed on the touch screen 30, and reflects the second image toward the visual position α. It is like that. The visual position α is a position at which the first image displayed on the touch screen 30 can be visually recognized and a position at which the mirror surface of the mirror 32 can be visually recognized.

  Therefore, the user who has the viewpoint at the visual position α can visually recognize the first image displayed on the touch screen 30 and at the same time, the second image reflected by the mirror 32 (that is, the second image reflected on the mirror 32). (Image) is also visible.

  Next, the internal configuration of the operation panel 5 will be described in detail. FIG. 6 is a block diagram showing the internal configuration of the operation panel 5.

  As shown in FIG. 6, the operation panel 5 includes a touch position detection circuit 60 in addition to the above-described hard key group 10, the touch screen 30 including the liquid crystal display panel 30a and the touch panel 30b, the mirror 32, and the touch panel 34 covering the mirror 32. The display control unit 50 is included.

  The touch position detection circuit 60 calculates a coordinate value indicating the touch position of the user on the touch panel 30b (that is, the touch position of the user on the touch screen 30) by detecting a change in the surface charge of the touch panel 30b. This is a circuit for inputting the calculated coordinate value to the display control unit 50. Further, the touch position detection circuit 60 detects a change in the surface charge of the touch panel 34 to calculate a coordinate value indicating the user's touch position on the touch panel 34 (that is, the user's touch position on the mirror 32). The calculated coordinate value is input to the display control unit 50.

  The display control unit 50 is a computer that controls the display operation of the liquid crystal display panel 30a, that is, the display operation of the touch screen 30, and includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. Composed. In particular, the display control unit 50 detects the touch position based on the coordinate value input from the touch position detection circuit 60, and the contents of the first image displayed on the touch screen 30 according to the detected touch position, Control for switching the content of the second image is performed. Below, the control content of the display control part 50 is demonstrated in detail.

  First, the display control unit 50 controls the touch screen 30 to display the input standby image in the operation mode currently set in the MFP 1 as the first image in the standby state where the MFP 1 is waiting for an instruction input from the user. I do. For example, when the copy mode is set in the MFP 1, as shown in FIG. 3, the input standby image 70 in the copy mode is displayed on the touch screen 30 as the first image.

  Here, when the user viewing the input standby image 70 displayed as the first image at the visual position α in FIG. 5 touches the touch screen 30, the display control unit 50 displays the touched position. Accordingly, the content of the second image displayed in the second direction is determined, and the image of the determined content is displayed as the second image.

  For example, as shown in FIG. 3, the input standby image 70 displayed as the first image is displayed to the user such as the special function button A, the double-sided copy button B, the copy density button C, the paper button D, and the magnification button E. Although it is a menu image including items for selection, it is assumed that the user touches the touch screen 30 so that the position where the special function button A is indicated is covered with a finger. In this case, the display control unit 50 detects the position indicated by the special function button A as the touch position based on the coordinate value input from the touch position detection circuit 60. Then, the display control unit 50 displays a special function setting image 71 (FIG. 7) corresponding to the special function button A, which is an image in a lower hierarchy with respect to the input standby image 70 while displaying the input standby image 70 as the first image. The operation of the touch screen 30 is controlled so as to display (see (a)) as the second image.

  Here, for the second image, the display control unit 50 performs control to display a mirror image of the image that should be originally shown to the user from the touch screen 30. Accordingly, as shown in FIG. 9A, when the touch screen 30 is viewed from the first direction side, the input standby image 70 as the first image is displayed on the touch screen 30, and the touch is performed from the second direction side. When the screen 30 is viewed, a mirror image of the special function setting image 71 as the second image is displayed on the touch screen 30. In FIG. 9A and FIG. 10A, FIG. 11 and FIG. 12, which will be described later, two touch screens 30 are shown, but only two are shown for convenience of explanation. There is actually only one touch screen 30. Specifically, in FIG. 9A, FIG. 10A, FIG. 11, and FIG. 12, the upper touch screen 30 shows the state of the screen viewed from the second direction side (see FIG. 5). The lower touch screen 30 shows the state of the screen viewed from the first direction side.

  The mirror image of the special function setting image 71 displayed on the touch screen 30 is guided to the mirror 32, and the mirror 32 reflects the mirror image toward the visual position α. Therefore, the image projected on the mirror 32 is an inversion of the mirror image, and the special function setting image 71 is projected on the mirror 32 in a form that should originally be shown to the user.

  As a result, the user whose viewpoint is located at the visual position α in FIG. 5 visually recognizes the input standby image (first image) 70 displayed on the touch screen 30, as shown in FIG. 9B. At the same time, the special function setting image (second image) 71 displayed on the mirror 32 in a form that should be originally shown to the user can be visually recognized. FIG. 9B shows the touch screen 30 and the mirror 32 as viewed from the visual position α in FIG.

  Further, as shown in FIG. 9B, the special function setting image 71 as the second image displayed on the mirror 32 is a user such as a binding margin button F, a saddle stitching button G, a multi-shot button H, or the like. For example, it is assumed that the user touches the touch panel 34 on the mirror 32 so that the position where the binding margin button F is indicated is covered with a finger. In this case, the display control unit 50 detects the position indicated by the binding margin button F as the touch position based on the coordinate value input from the touch position detection circuit 60. Then, the display control unit 50 displays the mirror image of the special function setting image 71 as the second image, and is a binding layer setting corresponding to the binding margin button F which is an image in a lower hierarchy with respect to the special function setting image 71. The operation of the touch screen 30 is controlled so that the work image 72 (see FIG. 7B) is displayed as the first image.

  10A, when the touch screen 30 is viewed from the first direction side, the binding margin setting image 72 as the first image is displayed on the touch screen 30, and the second direction. When the touch screen 30 is viewed from the side, the mirror image of the special function setting image 71 as the second image is displayed on the touch screen 30.

  Therefore, for the user at the visual position α in FIG. 5, the binding margin setting image 72 can be visually recognized as the first image displayed on the touch screen 30 as shown in FIG. 10B. The special function setting image 71 can be visually recognized as the second image displayed on the mirror 32. FIG. 10B shows the touch screen 30 and the mirror 32 as viewed from the visual position α in FIG.

  As described above, in the operation panel 5 of this embodiment, the liquid crystal display panel 30a is covered with the touch panel 30b to configure the touch screen 30, and the mirror 32 is also covered with the touch panel 34. A user whose viewpoint is positioned at the visual position α can visually recognize the first image displayed on the touch screen 30 and can visually recognize the second image displayed on the mirror 32. Here, when the user touches the touch screen 30 so that any button (selection item) shown in the first image is covered with a finger, the first image is displayed on the touch screen 30 while this is being displayed. An image corresponding to the button, which is an image in a lower hierarchy with respect to the first image, can be displayed on the mirror 32 as a second image. Further, when the user touches the mirror 32 (that is, the touch panel 34) so as to cover any button shown in the second image displayed on the mirror 32, the second image is displayed on the mirror 32. The image corresponding to the button that is a lower layer image with respect to the second image can be displayed from the touch screen 30 as the first image. In other words, according to the above configuration, the user can simultaneously view the upper layer menu image and the lower layer menu image corresponding to the item selected by the user from the upper layer menu image. .

  In the above, when the input standby image 70 shown in FIG. 3 is displayed as the first image, when the user touches the position indicated by the special function button A, the special function button A is displayed. The mode in which the mirror image of the function setting image 71 (see FIG. 7A) is displayed as the second image from the touch screen 30 has been described. For example, the user shows the duplex copy button B in the input standby image 70. When the touched position is touched, a mirror image of the double-sided copy setting image 78 shown in FIG. 8D is displayed as the second image. Further, when the input standby image 70 shown in FIG. 3 is displayed as the first image, when the user touches the position indicated by the copy density button C in the input standby image 70, FIG. A mirror image of the copy density setting image 75 shown in FIG. 8 is displayed as the second image, and when the user touches the position indicated by the paper button D in the input standby image 70, the paper shown in FIG. When the mirror image of the setting image 77 is displayed as the second image and the user touches the position indicated by the magnification button E in the input standby image 70, the magnification setting image 76 shown in FIG. A mirror image is displayed as the second image.

  In the above, as shown in FIG. 9B, when the special function setting image 71 as the second image is displayed on the mirror 32, the position at which the user indicates the binding margin button F is displayed. The touch margin setting image 72 (see FIG. 7B) corresponding to the binding margin button F is displayed on the touch screen 30 as the first image when touching. When the position indicated by the saddle stitch button G is touched, the saddle stitch setting image 73 (see FIG. 7C) corresponding to the saddle stitch button G is displayed on the touch screen 30 as the first image. When the user touches the position indicated by the multi-shot button H in FIG. 9B, the multi-shot setting image 74 (see FIG. 7D) corresponding to the multi-shot button H is the first image. T It will be displayed on the screen 30.

  In the present embodiment, the job list image can be displayed on the touch screen 30 by pressing the job status key 28 in FIG. 3, and this will be described below. When the display control unit 50 in FIG. 6 detects that the job status key 28 in the hard key group 10 is pressed, the first job list image (first image) 85 is directed from the touch screen 30 in the first direction. Is displayed and a mirror image of the second job list image (second image) 86 is displayed from the touch screen 30 in the second direction.

  Accordingly, as shown in FIG. 12, when the touch screen 30 is viewed from the first direction side, the first job list image 85 is displayed on the touch screen 30, and the touch screen 30 is viewed from the second direction side. In this case, a mirror image of the second job list image 86 is displayed on the touch screen 30. From the viewpoint of the user whose viewpoint is located at the visual position α, the first job list image 85 displayed on the touch screen 30 can be viewed at the same time as shown in FIG. 2 The job list image 86 can be visually recognized.

  Here, as shown in FIG. 12, in the first job list image 85, three job file names are shown, and in the second job list image 86, the relationship with the size of the first job list image 85 is shown. Thus, the other five job file names not shown in the first job list image 85 are shown supplementarily, and the user can confirm the eight job file names at the same time. That is, in the second image (second job list image 86), information to be supplemented with respect to the information shown in the first image (first job list image 85) is shown.

  On the other hand, if the first job list image 85 and the second job list image 86 are displayed simultaneously on a normal display panel that does not have a dual view function, both images must be reduced and displayed. It becomes difficult to visually recognize each job file name. In addition, when the first job list image 85 and the second job list image 86 are displayed in order, the user can confirm at most five job file names at the same time, as in the present embodiment. The eight job file names cannot be confirmed at the same time.

  In the configuration described above, the operation panel 5 having the touch screen 30 and the mirror 32 corresponds to one mode of the display device of the present invention. The touch screen 30 functions as a display unit that displays the first image in the first direction and simultaneously displays the second image different from the first image in the second direction different from the first direction. The mirror 32 has a function as reflecting means for reflecting the second image displayed on the touch screen 30 toward the visual position α where the first image can be visually recognized. Thereby, at the visual position α, the first image displayed on the touch screen 30 can be visually recognized, and at the same time, the second image reflected from the mirror 32 can be visually recognized.

  The reflecting means for reflecting the second image displayed on the touch screen 30 toward the visual position α is not limited to the mirror 32. Instead of the mirror 32, a translucent glass or a translucent resin is used. A glossy resin, a glossy metal, or the like may be used as the reflecting means. This is because even with such a reflection means, it is possible to reflect the second image.

  In the present embodiment, the dual-view liquid crystal display panel 30a is used in the touch screen 30, but the first image is displayed in the first direction and the second image is displayed in the second direction at the same time. The present invention is not limited to the dual-view liquid crystal display panel 30a as long as it has a display function, and the present invention can be realized using a multi-view liquid crystal display. Further, as described in [0076] of Patent Document 1 and [0137] of Patent Document 2, the dual-view method or the multi-view method can be realized other than the liquid crystal display panel. Instead, the present invention can be realized by using, for example, an organic EL panel or CRT.

  Furthermore, it is not limited to the form which comprises the said reflection means with the single mirror 32 like this embodiment, You may comprise the said reflection means with a some mirror. For example, the mirror f that reflects the second image displayed on the touch screen 30 in a direction different from the first and second directions, and the second image reflected from the mirror f is further reflected toward the visual position α. The reflecting means may be constituted by the mirror g to be operated.

  Further, as shown in FIG. 9A or 10A, the second image displayed on the touch screen 30 is a mirror image of the image to be shown to the viewer. Therefore, the second image reflected from the mirror 32 is an image to be shown to the viewer, and allows the viewer at the visual position α to visually recognize the image to be shown instead of the mirror image. it can.

  Furthermore, in this embodiment, as shown in FIG. 4, the open / close panel 31 on which the mirror 32 is formed is configured to be rotatable, and by this rotation, the screen of the touch screen 30 and the mirror surface of the mirror 32 are The angle between the two is adjustable. Thereby, the reflection angle of the mirror 32 can be adjusted to an angle suitable for the viewpoint (eye position) of the viewer at the visual position α.

  In the present embodiment, the mirror surface of the mirror 32 is preferably the same area as the screen of the touch screen 30 and a larger area than the screen of the touch screen 30. Accordingly, the entire second image displayed from the touch screen 30 can be reflected by the mirror 32, and the inconvenience that only a part of the second image displayed from the touch screen 30 is reflected by the mirror 32 can be suppressed.

  Furthermore, in the present embodiment, each of the first and second images is a menu image in which a plurality of buttons (selection items) that are to be selected by the user are shown. Thereby, it is possible to make the user visually recognize two types of images showing a menu showing selection items.

  In the present embodiment, the mirror 32 is covered with the touch panel 34, and the first image displayed on the touch screen 30 is a button (selection item) that allows the user to select by the user's touch operation on the touch screen 30. Are displayed, and the second image displayed on the mirror 32 includes a plurality of buttons (selection items) that are selected by the user by the user's touch operation on the touch panel 34. Further, the user touches the touch screen 30 and selects a button shown in the first image displayed on the touch screen 30 to select the first image while displaying the first image on the touch screen 30. The lower layer image corresponding to the selected button can be displayed on the mirror 32 as the second image. Further, by touching the touch panel 34 covered with the mirror 32 and selecting the button shown in the second image displayed on the mirror 32, the second image is displayed on the mirror 32 and selected. The lower layer image corresponding to the selected button can be displayed on the touch screen 30 as the first image.

  In the operation panel 5 of the present embodiment, the mirror 32 that projects the second image is covered with the touch panel 34, and various buttons shown in the second image can be selected by a touch operation on the touch panel 34. Even if the mirror 32 is not covered with the touch panel 34, the various buttons shown in the second image can be selected by a touch operation. Specifically, only the touch screen 30 accepts touch operations for various buttons shown in the first image and the second image.

  For example, as shown in FIG. 11, a first area 81 and a second area 82 are set on the touch screen 30, and only the touch operation for various buttons (selection items) shown in the first image is performed for the first area 81. The acceptance and the second area are configured to accept only touch operations on various buttons (selection items) shown in the second image.

The user can select various buttons shown in the binding margin setting image 72 as the first image by performing a touch operation on the first area of the touch screen 30. On the other hand, by performing a touch operation, various buttons shown in the mirror image of the special function setting image 71 as the second image can be selected. This
By the touch operation on the touch screen 30, not only the various buttons shown in the first image but also the various buttons shown in the second image can be selected.

  However, for the user at the visual position α shown in FIG. 5, the mirror image of the special function setting image 71 as the second image displayed on the touch screen 30 cannot be viewed. Therefore, as shown in FIG. 11, the user refers to the special function setting image 71 as the second image displayed on the mirror 32, and displays the special function setting image displayed on the touch screen 30. The position of various buttons in the mirror image of the (second image) 71 is predicted, and the touch operation is performed on the second region 82 of the touch screen 30.

  As shown in FIG. 11, when the touch screen 30 is viewed from the first direction side, a binding margin setting image 72 as a first image is displayed. In the binding margin setting image 72, the binding margin setting image 72 is displayed. Various buttons are shown only in a range overlapping the first area 81. Further, when the touch screen 30 is viewed from the second direction side, a mirror image of the special function setting image 71 as the second image is displayed. In the mirror image of the special function setting image 71, the second image Various buttons are shown only in a range that overlaps the area 82.
