A display 4 with a touch panel on the front
The display 4 shows a perspective view 55 in which four push keys are viewed from the left side.

When the operator touches, for example, the second push key from the right in the perspective view 55, as shown in FIG. 9, the black and white of the push key is reversed to display to the operator that the touch operation has been accepted. Has become.

[Problem to be Solved by the Invention] In the above-described conventional device, when the operator touches the push key displayed on the display 4, the black and white of the push key is reversed.

However, it is unnatural that the operator pushes the push key but does not move back and forth, but simply reverses the black and white.

Further, as shown in FIG. 10, when the electronic device 51 is installed at a position where the light L strikes from the upper left side, a shadow can be formed on the right side and the lower side with the real push key 3, so that it protrudes slightly toward the left side. Looks like

However, even in this case, the perspective view 55 of the push key displayed on the display 4 is a perspective view as viewed from the left side and protrudes toward the right side, so that both are unified and give an uncomfortable feeling to the operator.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a touch panel type input device that displays push keys without giving an uncomfortable feeling to an operator.

[Means for Solving the Problems] According to a first aspect, a touch panel type input device of the present invention displays an icon on a screen of a display having a touch panel mounted on a front surface, and touches the icon to display a predetermined icon. In a touch panel type input device for performing input, key pattern storage means for storing at least a perspective view of a state where a push key protrudes forward and a perspective view of a state where a push key is pressed backward, and one of the perspective views as an icon And a display pattern switching means for displaying the other of the perspective views when the icon is touched.

According to the second aspect, an icon is displayed on a screen of a display in which a touch panel is mounted on a front surface, and in a touch panel type input device that performs a predetermined input by touching the icon, the inclination of a light beam hitting the screen is determined. Optical sensor means for detecting, a key pattern storage means for storing at least a right perspective view of the push key viewed from the right and a left perspective view viewed from the left side, and the inclination of the light beam detected by the optical sensor means A display pattern switching means for displaying the right perspective view at the time and displaying the left perspective view when viewed from the right is provided.

[Operation] In the touch panel input device according to the first aspect of the present invention, when a push key displayed on the screen is touched, the push key changes to a display projecting forward or to a display pressed backward. Or Since this is a change in which the push key moves back and forth according to the operation of the operator, the operator does not feel uncomfortable.

Further, in the touch panel type input device according to the second aspect, since the push key automatically becomes the right perspective view or the left perspective view according to the inclination of the light beam, the push key can be unified with the real push key, and the operator can feel uncomfortable. I do not receive.

[Example] Hereinafter, the present invention will be described in more detail with reference to an example shown in the drawings. It should be noted that the present invention is not limited by this.

FIG. 1 shows an electronic apparatus 1 incorporating a touch panel type input device (10 in FIG. 3) according to one embodiment of the present invention.

A push key 3 is installed on the operation unit 2 of the electronic device 1, and light L strikes from the upper right side, so that shadows are formed on the left side and the lower side.

In addition, a display 4 having a touch panel (16 in FIG. 3) mounted on the front is installed.
5 shows a perspective view 5 in which four push keys are viewed from the left side.

Further, a light receiving window 6 is provided near the display 4, and inside the light receiving window 6, as shown in FIG. 2, a light receiving element 9A such as CdS directed to the left and a light receiving element 9A to the right. The directed light receiving element 9B is attached.

FIG. 3 shows a main part of the touch panel type input device 10 incorporated in the electronic device 1.

The light receiving elements 9A and 9B are connected in series, and the voltage at the connection is input to the direction discriminating unit 12 via the A / D converter 11. The voltage at the connection portion approaches the GND voltage when the light L strikes from the right side, and approaches the + V voltage when the light L strikes from the left side. Therefore, the direction determining unit 12 determines the inclination of the light L from the input voltage, and outputs a result of the determination to the pattern extracting unit 13.

The pattern extracting unit 13 extracts the pattern of the perspective view of the push key stored in the pattern storage unit 14 and outputs the pattern to the display control unit 15.

The pattern storage section 14 stores perspective views of push keys in various states as shown in FIG. (A) is a state in which all four push keys protrude forward as viewed from the left, and (d) is a state in which the second from the right is pushed down rearward. (B) is a state in which all four push keys protrude forward as viewed from the front, and (e) is a state in which the second from the right is pushed down rearward. (C) shows a state where all four push keys protrude forward as viewed from the right side, and (f) shows a state where the second from the right is pushed down rearward. Of course, other states are also stored.

The pattern extracting unit 13 selects a perspective view viewed from the left side, a perspective view viewed from the front side, or a perspective view viewed from the right side according to the determination result of the direction determining unit 12. Then, at first, the one in a state where all the push keys protrude forward is selected.

The display control unit 15 displays the perspective view selected and taken out by the pattern taking out unit 13 on the display 4.

Therefore, for example, if the light L is incident from the right side, (a) in FIG. 4 is selected at first, and the display state is as shown in FIG.

Here, when the operator touches the second push key displayed on the display from the right, the touch panel reading unit 17 detects the touch and notifies the pattern extracting unit 13. Then, the pattern extracting unit 13 selects (d) in FIG. 4, and as a result, the display state is as shown in FIG.

As described above, the display of the push key on the display 4 indicates a change corresponding to the operation of the operator, so that the operator does not feel uncomfortable.

When the electronic device is installed in a place where the light L strikes from the front, the pattern extracting unit 13 selects the perspective view of the push key as viewed from the front, and the display state is as shown in FIG.

When the light L is set at a place where the light L strikes from the left side, the pattern extracting unit 13 selects a perspective view of the push key viewed from the right side, and thus the display state is as shown in FIG.

As can be understood from FIGS. 5 to 7, the shadow produced by the real push key gives the impression that the key protrudes in either direction. Since the displayed direction of the push key always matches, the operator does not feel uncomfortable.

The perspective view may be stored in the form of graphic data, or may be stored in the form of an operation for generating a perspective view corresponding to the viewing direction based on the basic three-dimensional shape of the push key.

In addition to the above configuration, a conventional black-and-white inverted display may be performed.

[Effects of the Invention] According to the touch panel input device of the present invention, it is possible to eliminate an uncomfortable feeling of the operator with respect to the touch panel. For this reason, a secondary effect that can suppress occurrence of erroneous input also occurs.
