Title: Reproducing device of disk record
Inventor: KATAYAMA YOSHITAKA
IPC: G11B19/02
Filed: 1983-08-31
Abstract: PURPOSE:To easily grasp the whole aspect of music even if it starts at a low level by starting play when a reproduced tone rises above a set level in music scan play mode, and reproducing the next music after specific-time play. CONSTITUTION:Read music data is sent to a comparing means, and its amplitude level is compared with the preset level; when the reproduced data is higher than the set level, the play mode is entered to drive a speaker and a time-limit means starts specific-time clocking at the same time. The time limit means sends a driving signal to a pickup driving signal generating means a specific time later. This signal generating means generates a driving signal for moving a pickup signal to the next address with the driving signal from the time-limit means, thereby moving the pickup at a high speed. When the music is lower than the set level, on the other hand, the next music is compared similarly. This operation is repeated to grasp the all states of all pieces of music easily.
