<p>PURPOSE:To unnecessitate the moving of a cursor and to improve the operability at the time of performing various kinds of instructions and setting by simultaneously turning on plural push buttons for frequent indication or instruction. CONSTITUTION:An operator turns on push buttons 81,82 of a mouse simultaneously. Further, at this time, the position of the cursor on a display screen has nothing to do with the operation, so that the cursor can be at any position. A control circuit 83 outputs a signal indicating the state where both push buttons are turned on against a signal output circuit 85, and the circuit 85 converts this signal into the one for external output to be sent to a CPU34. When recognizing this signal, the CPU34 takes the contents of instruction or setting or the like indicated by the operator so far in a main memory, judges whether or not all the screen is finished, and switches the display of a CRT display device to the next display contents at the time of NO. Thus, the instruction, setting, etc., to an electronic filing device can be performed with simple operation.</p> |
