<p>PURPOSE:To ensure the selection and the repetitive reproduction of the desired music in case both the music name and the music No. are unknown, by securing the automatic reproduction for a fixed time for each head part of several pieces of music recorded. CONSTITUTION:In case the quick reproduction is desired for the head part of next recording bands B and C each when magnetic head 111 is at recording band A of magnetic tape 101, both mode change-over switch 121 and reproduction switch 122 are turned on simultaneously. Thus transistors TR401 and 402 of plunger control unit 400 are turned on to secure the quick sending reproduction, i.g., the cue mode. Then inter-music detector 200 detects the silent band to give switching to the reproduction mode after a fixed time, and then reproduces the heat part of recording band B. When the pulse signal of monostable multivibrator 302 does not exist after another fixed time, TR401 is turned on. And plunger 131 is rest to the cue mode again. This action is repeated to know the contents of recording bands A, B and C each of tape 101. At the same time, the desired recording band can be selected for the music in a short time.</p> |
