<p>PURPOSE:To achieve program search for a plurality of recorders at the same time, by changing the duty of rewinding pulses and fast feed within a prescribed period through the use of a microprocessor and independently excercising control over each recorder. CONSTITUTION:A program search device and n sets of recorders 16 and 17 are connected to tape address input ports 10 and 12 via FF/RWD pulse outut rate control ports 11 and 13. When an interrupting signal from an nf0 oscillator 14 is received by a CPU9, the CPU9 reads an interrution vector address data outputted from an interruption vector output port 15 via a data bus. The CPU9 reads a tape address of a designated recorder with a read-in interruption vector address data and outputs the FF/RWD pulse for the read-in and program search to the said recorder. The interruption vector address sequentially designates the recorders from 1, 2..., n sequentially, and each recorder can independently receive the program search control in a time interval of 1/f0.</p> |
