PURPOSE: To provide a means that enables to sound a fanfare or light up a display lamp when a ball hit with a stick passes through a gate.
CONSTITUTION: A light-emitting element 11 and light-receiving element 12 are attached to legs 1a and 1b of a gate, and the elements detect a ball 2 which passes through between the legs 1a and 1b. When the ball 2 fully passes through, the light-receiving element 12 outputs a signal which is detected by a detection circuit 13. A signal from the detection circuit 13 actuates a solenoid driving circuit 14, and a plunger 5b of a solenoid 5 is raised to press and turn on a lever 15a of a microswitch 15. A control block 4 drives a sound element 16 to sound a fanfare and to light up a display lamp 8.
