PURPOSE:To simplify the operation of a disk record reproducer, by performing program searching for the desired music with a composite operation of numerical switches and a pause switch and a setting a pause state immediately after the end of said program searching. CONSTITUTION:If (0)-(9) numerical switches 311-320 are operated independently of each other, a numerical key input control signal is supplied to a numerical key input control signal input terminal T2 of a control circuit 201 via an AND gate 327 by a set output Q given from the 2nd flip-flop circuit 323 which is set via an OR gate 326 and a reset output Q of the 1st flip-flop circuit 322. As a result, only a digit key process (in memory operation state) is carried out as if the numerical key input data were fetched to a numerical key input data bus T3 of the circuit 201 without having a searching operation. That is, a pickup 207 is shifted to a corresponding curved part on a disk 206 by transmitting a signal necessary for searching of a desired address to a disk reproduction system 202 from the circuit 201 via an external control circuit 203. |
