PURPOSE:To call passenger's attention with a reporting means a prescribed time before departure by providing a guide device incorporating a register, a timer means, a counted-up value comparing means, and the signal output reporting means. CONSTITUTION:A register A incorporates a clock 11 which counts the present time, and numerical information indicating the present time from this clock is applied to an arithmetic processing circuit 12, and numerical information related to a predeterminate departure time is inputted. The circuit 12 compares numerical information related to the determinate departure time and that indicating the present time from the clock 11 with each other and outputs numerical information X corresponding to the time to departure. A guide device B incorporates a register 15, and information X is inputted to the register 15, and a timer start signal Y is applied to a timer circuit 16 from the register A to start counting. This counted value is compared with the timer to departure, and a control output is generated and is sent to an oscillator 18 when a comparing circuit 17 detects coincidence between information X and numerical information of the elapsed time from the circuit 16. |
