<p>PURPOSE:To perform recording at a desired time and record the count value of control pulses at the start and the end of this recording, by providing a timer mechanism to store the start time and the end time of the timer operation. CONSTITUTION:RAM13 is provided with a timer memory, and every two addresses are paired to store the start time and the end time of the time operation. First, timer data in the first address of the timer memory is read out; and when this data agrees with the count value of a clock signal, the recording state is set. Simultaneously, the count value of control pulses at this time is stored in the program memory of RAM13. When the recording state is set, timer data in the second address of the timer memory is read out; and when this data agrees with the count value of the clock signal, the stop state is set. Simultaneously, the count value of control pulses at this time is stored in the program memory. These operations are repeated prescribed-number times. Programs for these operations are stored in ROM12.</p> |
