<p>PURPOSE:To facilitate section selecting operation, by performing initial setting, setting of the number of jump sound reproduction/recording sections, and section detecting operation relationally, and selecting a sound reproduction/recording section. CONSTITUTION:The number of jump sections is set by pressing a switch 34 in order and applying a voltage Vcc to a set input terminal 10, and this signal input is supplied as a resetting control input for initial setting to the 2nd initial setting circuit 6. On the basis of a rapid traverse reproduced input signal S, a sound unrecorded-section detecting circuit 8 detects a sound unrecorded section to detect the passed number of sound recorded parts, thereby detecting a detection signal. The detecting circuit 8 is applied with said voltage Vcc as an operation control input through switches 22 and 32. A display circuit 36 is provided with a driving circuit 38 driven by the output of a storage circuit 2 and to three output terminals 40, 42, and 44 formed corresponding to the number of storage of this driving circuit 38, light emitting diodes 46, 48, and 50 are connected as display elements.</p> |
