Filed: 1983-02-07
Abstract: PURPOSE:To obtain a control circuit suitable for automatically repeated operation by performing a halting of count and a zero setting with a timing control signal for a stop watch for first draw play. CONSTITUTION:When the timing signal Ts gets to a high level by the operation of a manual switch or the like, an output start-stop signal S-s moves to a high level at an output terminal Q of an FF17 by a setting pulse Tc-1. At the same time, a gate signal Tc-2 turns to a high level and the output counting signal Cs of an AND circuit 18 also gets to a high level, causing a time section to start counting. A signal lamp lights with the signal Cs as start signal SAs to make a player start playing. In case a sensor pulse Sp fails to be generated due to a trouble of the player, a timing signal Ts returns to a low level with the expiration of the period of setting the automatic operation and by manual operation or the like and making the gate signal Tc-2 return to a low level and the signal Cs also to a low level to stop the counting with the time section. At the same time, a zero setting signal Zs becomes effective to zero-set the time section.
