Abstract

PURPOSE: To execute always good random access operation by disabling reject function at the random access reproduction mode thereby inhibiting the forceful pause of a reproduction element.
CONSTITUTION: When an automatic resetting action starting micro-switch MSW2 is turned On instantaneously while an operating function change switch SW is OFF, a transistor TrQ3 does not go ON and therefore the intrinsic reject function in an information signal reproducer is disabled and TrQ2 is turned OFF and TrQ1 OFF by the TrQ5 which goes ON over the set time determined by the charging time constant of a time constant circuit to which the switch MSW2 is connected from the time when this switch is instantaneously turned ON, then changing-over of a driving circuit by a relay RL1 which is driven only during this time causes the carriage to rapidly transfer the reproducing element to the information signal recording side of the disc. Thereby, always good random access operation may be executed.
