<p>PURPOSE:To select music in a short time, by prolonging reproduction time through the operation of a user when the user can not recognize the contents of music. CONSTITUTION:When an SW botton SCAN is pressed, an automatic music selecting device starts operating and a microcomputer 7 turns on an SEARCH soleniod SS and a motor M to hold intermusic gap detection in readiness. When an L potential output is obtained continuously at an intermusic gap, a decision on the intermusic gap is made and after a mechanism is stopped, reproduction mode is made effective. At this time, the user know the contents of music, but when a playback button is pressed after the music is reproduced for a prescribed time, the reproduction is carried on and when not, intermusic gap detection is performed after the mechanism is stopped temporarily. Therefore, the music selection is carried out in a short time.</p> |
