Abstract

PURPOSE: To enable to ensure the program search of designated recordings in any case, by constituting that the detection signal between recordings is not passed through for a given period when the record disc size detection signal is obtained.
CONSTITUTION: The masking circuit 13 is triggered with the 1st recording detection signal m11 via the sensor 11 between recordings, and the masking output is produced so that the signal m11 is not passed through for the specified period T. From the record disc size sensor 12, an output is given under the condition that no reflected light is obtained from the reflected section provided on the turn-table, and it is given as the set signal for R-S.FF15 via the record discrimination circuit. Thus, the record disc size detecting signal accompanying slight delay from FF15 is fed to the masking circuit 13, it is triggered again and the masking output is caused for a given period again with retrigger. Thus, with the constitution like this, sure program search can be made for the designated recording, since the 2nd detection signal m12 between recordings can not be passed.
