<p>PURPOSE:To use plural tape recorders simultaneously and to control their tape runs by controlling tape runs by instructions through interface circuits for the tape recorders. CONSTITUTION:A cassette magnetic tape (CMT) interface circuit 69 modulates a serial signal inputted from a CMT output signal line 67 to output the resulting signal to the microphone jack 76 of a tape recorder 69, and also demodulates a signal from an earphone jack 77 to output the demodulated signal to a CMT input signal line 66. Relays 73 and 74 control remote signals of tape recorders 68 and 78 respectively and are controlled by relay drivers 71 and 72 according to a signal outputted from an I/O port 70. Thus, one tape recorder is used as an external storage device, and the other is used for normal sound recording and reproduction.</p> |
