PURPOSE:To execute the input operation by means of a blind touch, by constituting the apparatus so that it has different input functions in accordance with the operating direction of plural respective lever switches. CONSTITUTION:This small-sized electronic apparatus 1 is equipped with a register lever 2 and an operation lever 3. The lever 2 is guided by the cross guide groove 4 and can be switched up and down, to the right and left, and in depressed direction, and it is set so that it can be input of 5, input of 1, left shift, right shift and input of decimal point by laying down upward, laying down downward, laying down to the left, laying down to the right and depressing it, respectively. On the other hand, when the lever 3 is laid down upward, downward, to the left and to the right, the apparatus becomes an operation state of +, -, X and divided by , respectively, and also it becomes an operation state of=by depressing the lever. For instance, registering of 7 is executed by switching 5 once and 1 twice, that is to say, operating the lever 2 upward once, and downward twice. As a result, the input operation can be executed by means of a blind touch, and if the display is possible, the workability of the apparatus in a dark place and a vibrating place can be elevated remarkably. |
