| Abstract: |
An optoelectronic amusement device has a transmitter that emits pulses of a controlled pulse train duration, pulse rate and pulse width, and at a frequency of at least about 1800 hertz. A receiver is employed which is sensitive to the pulse rate and frequency of the transmitter. The transmitter is incorporated into a firearm replica for a shooting gallery and the receiver is a target displaying a visible light source which is extinguished for a predetermined time period when energy from the transmitter strikes the target.

I claim:
1. An optoelectronic transmitter means for use in an amusement park shooting gallery, said transmitter means emitting infrared energy and being mounted in a firearm replica, said transmitter means including:
- transducer means for converting electrical input energy into infrared energy, said transducer means being mounted in said replica to emit said infrared energy along a barrel of said replica;
- lens means mounted in said barrel for focusing said infrared energy into a narrow beam which emanates from said barrel;
- pulse generating means for generating electrical input energy including frequency gating means for gating pulses at a predetermined pulse rate of at least about 1800 hertz frequency to said transducer means, said pulse generating means being selectively enabled by a manual trigger signal, said pulse generating means including a monostable multivibrator triggered by an oscillator; and
- pulse train duration control means connected to said pulse generator means for operating said pulse generator means only for a predetermined time duration, said pulse train duration control means including a resistor-capacitor timing circuit with its output connected to the inputs of a NOR gate, the output of the NOR gate being connected to said pulse generator means whereby the charging of said capacitor to a predetermined voltage causes said NOR gate to change state.
