<p>PURPOSE:To improve the operability of a tape recorder, by setting the address of the desired music at a microcomputer and then pushing an automatic music selection button to secure the automatic rewinding back to the head of a tape and to perform the selection of music. CONSTITUTION:The signal recorded on a magnetic tape 101 is reproduced by a reproducing head 102 and delivered to a terminal 104 via an amplifier 3. The reproduced signal is also supplied to a microcomputer 300 via a rectifier 105. The computer 300 contains a storage part 301, an arithmetic part 302, a control part 303, an input part 304 and an output part 305. for an operation for the automatic selection of music, a storage button 601 is pushed to set the address of the desired music and then an automatic music selection button 605 is pushed. The information is stored at the part 301 and then rewound by a driving part 200. The pulse of a tape end detecting circuit 501 is detected, and the tape is rewound back to the head. Then the selection of music is started, and the inter- music signals supplied from the rectifier 501 are counted. Then the reproduction is started when the tape reaches the desired music address.</p> |
