<p>PURPOSE:To validate the least number of keys to an input instruction and to increase the number of input instructions on a single screen by recognizing a parallax error between a key input means and a display means via a parallax error amount instruction means and enabling an operator himself/herself to easily correct the error caused by parallax via a parallax error correction means. CONSTITUTION:An input device 1 consists of a liquid crystal display 2, a touch panel 3 provided on the surface of the display 2, and a cover 4 of the panel 3. The display screen of the panel 3 can be freely slid up and down via the guiding members 5 and 6 provided on both sides of the panel 3. In addition, the guiding members 7 which can fix the panel 3 at an optional position with friction are provided on the upper and lower edge parts of the panel 3. Then a message 25a for the input of number, for example, is displayed together with the display of the ten keys 25b in an input operation mode. Then the touch keys 13 provided on the upper surfaces of the displayed keys 25b are pushed and the key signals corresponding to the number of the keys 25b are inputted. Thus the contents and the display are changed every time the mechanical operation and the step state are changed to input them sequentially.</p> |
