In FIG. 1, the touch input device includes a touch input panel 11, a touch input panel control mechanism 12, and a function display device 3, and the touch input panel 11 is provided on the front side of the function display device 3. The structure is arranged at a position facing the function display surface 4.

In the touch-type input device having such a configuration, the operator is notified of the function region of the touch-type input panel 11 by displaying the function region on the function display surface 4 of the function display device 3. The operator has adopted a control method of inputting by touching the touch-type input panel 11 in the portion where the desired function is displayed.

[0004]

In the conventional control system of the touch input device, the touch input panel 1 is used.
If 1 is touched, it is determined that the touched position has been selected and input immediately. Therefore, there is a parallax that the apparent functional area generated when the touch input device is viewed obliquely differs from the actual functional area. As a result, if functional areas having different meanings were defined adjacent to each other, they could be erroneously input.

Further, since the operator of the functional area of the touch input panel 11 is notified only by the function display, when the visually impaired person tries to operate this input device, which one on the touch input panel 11 is to be operated? I couldn't know what kind of function the part corresponds to, and I couldn't touch it to check, so I couldn't operate it at all.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and an object thereof is to prevent erroneous input and also to enable touch operation by a visually impaired person. To provide a device.

[0007]

In order to achieve the above object, the touch type input device according to the present invention has a function of determining an input position on the touch type input panel and determines that the determined input position is input. It has a two-layer structure with functions. Further, another touch type input device according to the present invention further includes a voice generation unit.

[0008]

In the touch-type input panel of the touch-type input device according to the present invention, when the first layer of the touch-type input panel is activated by being touched by the operator, which part is currently in contact is the functional position. An input control for notifying the operator by the function display device that the operator further pushes the touch-type input panel to determine that the functional portion selected in the first layer has been input when the second layer becomes effective. In this method, the operator knows the function to be input in advance before the input is fixed, and if the function is not the desired one, the operator can change the position and touch it again, thereby reducing erroneous input.

The voice generating means in the touch input device according to the present invention uses voice to notify the operator of which functional position the currently touched portion on the touch input panel is. Even if the operator is visually impaired, he / she can search for a functional position and make an input while touching the touch input panel.

Embodiments of the present invention will be described in detail below with reference to the drawings. 1A and 1B are views showing a configuration of an embodiment of a touch type input device according to the present invention. FIG. 1A is a perspective view and FIG. 1B is a sectional view taken along the line AA '. In FIG. 1, the touch type input device has a touch type input panel 1, a touch type input panel control mechanism 2 and a function display device 3, and a touch type input device is provided on the front side of a function display surface 4 of the function display device 3. The input panel 1 is configured to be located. As shown in FIG. 1B, the touch input panel 1 includes a function determining touch detection layer 6, a touch detection layer intermediate film 8, a function selection touch detection layer 5, and a touch on a touch input panel base 9. The touch panel has a laminated structure in which the formula input panel surface film 7 is stacked, that is, the touch detection layer is composed of two layers.

In such a configuration, when the touch input panel 1 is lightly touched, the function selection touch detection layer 5 which is the first touch detection layer becomes effective, and when the touch input panel 1 is pushed further, The function-determining touch detection layer 6 which is the touch detection layer of is effective.

The function area is presented to the operator by displaying it on the function display surface 4. When the operator touches a point on the touch-type input panel 1 with a fingertip or the like and the function selection touch detection layer 5 becomes effective and is within the effective function area,
The display form of the corresponding function area display on the function display surface 4 is changed, and the function to be input when the touch input panel 1 is pushed forward is presented to the operator. At this point, the input is not yet validated, and when the operator releases the touch-type input panel 1, the functional area display form is restored.

When the operator desires to input a function indicated by the functional area currently touched and pushes the touch-type input panel 1 further to activate the function-determining touch detection layer 6, the function-selection touch detection layer 5 is selected. The function selected by the input of is input. This makes it possible to give the operator an opportunity to correct even if he touches an adjacent functional area due to parallax,
It is possible to prevent erroneous input due to parallax.
