PURPOSE:To feed stored data in response to the time data, by measuring the time elate read out from a storage means with a clock pulse having a shorter period than that at automatic playing. CONSTITUTION:In pressing a fast feed switch of an operation section 20, a CPU11 outputs a repetitive data to a control signal generating circuit 18. Then, a clock pulse phi2 from the circuit 18 is applied to the CPU11. Every time the clock pulse phi2 is given to the CPU11, ''1'' is subtracted from a data in a timer area and the result of subtraction is written in a timer area TE again. When the content of the timer area is ''0'', the timer data of the next event frame and the 1st word number data are read out from an RAM14 and written in the timer area and a temporary storage area respectively. Then, every time the pulse phi2 is outputted, the operations above are repeated. |
