PURPOSE:To easily detects an initiation point of songs. CONSTITUTION:A reproducing signal of CD-G software 1 is supplied to a signal processor 3 from a signal reading means 2. A time code data TCD is supplied to both system control means 7 and a backsearch control means 20a from the signal processor 3. A subcode signal SCA is supplied to a decoder 4 from the signal processor 3.2 When a detector 40 detects continuously an 'EXCLUSIVE-0RFONTWITH2C0L0URS' instruction, a time data obtained by subtracting the predetermined value from the time data of data TCD is stored in the backsearch control means 20a. A signal BSCD is supplied to the control means 7 from the control means 20a by manipulating a switch 9 and a control signal RPC is supplied to a reading means 2 for the returning operation. When the data TCD matches with the data stored in the control means 20a during the reproducing operation after the returning operation, count-down is started in the control means 41 for displaying count-down on the display 42. |
