CONSTITUTION:A floppy disk has such structure that a recording medium where a program is recorded is replaced freely, and the program recorded on a recording medium set to the disk 6 is executed by a processor 2. A picture responding to this program is displayed on a display device 1. A coordinate reading device 3 is connected to the processor 2 and transmits coordinates of the contacting position of an input pen 5 in response to the processor 2. A sheet 4 is provided on or under the device 3 at least attachably and detachably. The sheet 4 is provided with plural areas corresponding to operation items, which are required for the control of the execution of the program, so that they are discriminated visually. |
