PURPOSE:To execute easily read-out by only an electric power source turn-on operation without using a grammer for read-out by storing one program in one micro-floppy disk drive (memory capacity : 16K bytes). CONSTITUTION:When a power source is turned on, a CPU 5 is reset, and thereafter, a memory I/O, etc. 7 are initialized, and an input from a keyboard 8 is awaited. In this case, a monostable multivibrator 10 is operated by a reset signal from the CPU 5, and stimulates the keyboard 8. As a result, a program set to a micro-floppy disk drive 2 is read out and executed automatically. In this way, it is unnecessary for a user to input anything from the keyboard 8 by only turning on the power source, therefore, the operability is very good. This system is constituted so that an input from a full keyboard 3 is reduced as little as possible, and it will do by inputting only a ten key 4 or so. |
