PURPOSE:To improve the operability and to enrich a control system of a search function for a disk record reproducer by detecting that a pickup is stopped temporarily at a position opposite to the start part of the first data to be reproduced and then detecting that a down-operation element is operated in an effective period of the 1st detection signal to retrieve the start part of the final data to be reproduced. CONSTITUTION:A pickup feed motor is stopped and a pickup is in pause at the start address of the 1st music number. This state is detected by a head pause detecting circuit 313 for the 1st music number, and the circuit 313 delivers a detection signal. If a down-key 134 is operated in the output effective period of said detection signal, the 2nd flip-flop circuit 315 is set. Then the final music number search control signal is supplied to the input terminal of the final music number searching circuit 318 as well as to the 1st flip-flop circuit 314. As a result, a control circuit 201 transmits a signal necessary for search of the final music to a disk reproduction system via an external control circuit 203 for a searching action. |
