Abstract

PURPOSE: To reproduce a designated segment at a desired time and perform head positioning of the next designated segment, by providing a timer mechanism to set the address and the time corresponding to the desired segment.
CONSTITUTION: The time for operation start is stored in each odd-numbered address of the timer memory of RAM13, and data of segments to be reproduced are stored in a program memory. At an operation time, head positioning of the first segment is performed to set the stop state. Simultaneously, timer data in the first address of the timer memory is read out; and when this data agrees with the clock signal count value, reproducing is started. Further, this reproducing reaches the end of the segment, head positioning of the second segment is performed to set the stop state. Simultaneously, the third timer data of the timer memory is read out, and then, these operations are repeated prescribed-number times. Programs for these operations are stored in ROM12.
