CONTROL CIRCUIT OF TAPE RECORDERS

摘要

PURPOSE:To obtain a tape recorder having flexibility that multiple kind and intricate operations are done by the tape recorder itself by adding a microcomputer, a time generator and a plunger to a control circuit. CONSTITUTION:The control circuit is constituted by a voltile memory (RAM) 4 which regists instructions for causing certain operations to be effected and the time data of said operations, an input-output unit (I/O) 5 which detects the coincidence of the contents of the RAM of a microcomputer part 1 and the time data being inputted from a time generator 8 and outputs the sigual and an interface circuit 10 which drives a liquid crystal panel 12 for display and a plunger circuit 11 by the I/O port outputs. Such constitution enables the tape recorder itself to perform multiple kind and intricate operations, thus the tape recorder having flexibility such as automatic answering, etc. may be obtained.
