Abstract

An input device includes a touch panel which recognizes a press on each touch area and outputs press information and a controller which receives the press information output from the touch panel and transmits corresponding data to a main apparatus. The controller registers pressed regions of the touch panel and regions surrounding the pressed regions as touch areas in a touch area registration process performed prior to execution of data input operation. Upon receiving particular press information, the controller switches the kind of data to be input by pressing the touch areas and annunciates switching of the kind of input data by producing an audible message.

Claims

1. An input device comprising:

a touch panel which recognizes a press on a touch area and outputs press information; and

a controller which receives the press information output from said touch panel and transmits corresponding data to a main apparatus;

wherein said controller registers a pressed region of said touch panel and regions surrounding the pressed region as the touch area in a touch area registration process performed prior to execution of data input operation.

2. The input device according to claim 1, wherein said controller switches the kind of data to be input by pressing the touch area upon receiving particular press information.

3. The input device according to claim 1, wherein said controller switches the kind of data to be input by pressing the touch area if no press information is received within a specific period of time.

4. The input device according to claim 2, wherein said input device audibly annunciates switching of the kind of input data.

5. The input device according to claim 1, wherein said controller determines the value of input data from the number of successive presses on the touch area.

6. The input device according to claim 1, wherein more than one touch area is registered and said controller determines the value of input data according to a combination of touch areas from which press information has been received.

7. The input device according to claim 1, wherein said controller determines the value of input data by adding data corresponding to the number of successive presses on the touch area to existing data.

8. The input device according to claim 1, wherein said touch panel recognizes a sliding action along the touch area and transmits corresponding information to said controller, and said controller transmits corresponding data to said main apparatus.

9. A touch area registration method comprising the steps of:

receiving press information output from a touch panel;

transmitting data corresponding to the received press information; and

registering a pressed region of the touch panel and regions surrounding the pressed region as the touch area prior to execution of data input operation.
