Filed: 1986-04-09
Abstract: PURPOSE:To lock a device without a key and the like by registering a key input following a specific key input as a password in a password table when the depression of a specific key is detected and stopping the signal transmission from an input device. CONSTITUTION:When a lock direction key 5 is depressed, its code is detected by a CPU1. Then a register PAD is specified at a top address SAD in the password table provided in the RAM area 2 of the CPU1 (PAD=SAD), and the code of the lock direction key is written at the top address SAD. When a next key is keyed in, the register PAD is incremented, and a code signal corresponding to the pressed key is written at the incremented address. If the written code is the one of the lock direction key, the registration of a password ends. Where PAD=EAD is satisfied, only the code of the lock direction key is written in the password table. With the password registered in a RAM2, the transmission of the code signal to a host device from the input device is inhibited to attain a locked state.
