PURPOSE:To omit the labor and time of loading by loading a password code automatically at the time of applying a power source, and collating password numbers, by providing an accessing means which judges the code of the personal identification code other than a keyboard input means. CONSTITUTION:By applying the power source 7, a CPU4 is initialized. Next, the personal identification code stored and held in a second-order memory device is drawn out by the CPU4, and is loaded on a work area in a memory 2. However, in this state, an input from a keyboard 5 cannot be accepted. The fact is informed to a control part 3 via a line l3. When the password code is inputted from a panel 1, the control part 3 accumulates it in the memory 2 as an input data, and compares it with the personal identification code loaded already. When coincidence is obtained between them, the control part 3 informs the coincidence to the CPU4 via the line l3, and sets a flag 4B, and a state is set at an operation possible state possible to accept the input from the keyboard 5.
