PURPOSE:To make automatic guidance broadcast possible by sequentially storing a memory unit with count values of a counter every broadcast spot in trial operation and by driving a tape recorder on the basis of those stored values. CONSTITUTION:At the 1st stop A, trial operation starts and at an adequate place before display change stop B, switch 22 is operated. With switch 22 operated, a shift pulse is supplied to memory unit 13 to read the count value of counter 2. On arrival at stop B, switch 21 is operated to supply memory unit 6 with a shift pulse and the count value of counter 2 is stored. On arrival at the next guidance broadcast spot, the contents of unit 13 are shifted into the next memory area by operating switch 22 and the count value of counter 2 is remembered by unit 13. At every time of arrival at a stop and guidance broadcast spot, the above-mentioned operation is repeated. In service started at stop A, proper guidance is broadcasted from the tape recorder on arrival at every guidance broadcast spot. |
