2,16 pin, 17 pin join.

The purpose of this utility model can also reach by following other measures: the wireless hit teller of described laser shooting, it is characterized in that the laser gun circuit by laser tube LD, pulse emission ic chip 1, triode T1, diode D1～D4, resistance R 1～R2, capacitor C 1～C5, K switch 1 and gunlock button AN constitute.Indication of shots score circuit is by laser pick-off assembly JS1～JS10, single-chip microcomputer ic chip 2, voice ic chip 3, triode T2～T4, resistance R 3～R15, capacitor C 6～C10, and quartz crystal X1, charactron LED1～LED3, loudspeaker Y1 and socket CZ constitute.Radio transmitter circuit is made of triode T5, T6, resistance R 16～R20, capacitor C 11～C20, coil L1, L2 and plug CT.Radio receiver circuit is made of FM reception ic chip 4, triode T7, T8, resistance R 21, R22, capacitor C 21～C38, coil L3, potentiometer W1 and loudspeaker Y2.

The utility model has following advantage compared to existing technology:

1. indication of shots score circuit etc. can directly be contained in the target plate back, and volume is little, little power consumption, use

Flexibly, not limited by the place.

2. line need not be set during long-range shooting, adopt radio transmission and receiving circuit to report

Target is particularly suitable for the moving target shooting.

3. cost is low, is convenient to popularize to use, can be widely used in military affairs, physical culture gunnery training and

Aspects such as amusement game.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the laser gun circuit theory diagrams.

Fig. 2 is indication of shots score circuit theory diagrams.

Fig. 3 is the radio transmitter circuit schematic diagram.

Fig. 4 is the radio receiver circuit schematic diagram.

The integrated package model is respectively among each figure: IC1 is that LC2190, IC2 are that AT89C51, IC3 are that ISD1420, IC4 are TDA7010.

As shown in Figure 1, the laser gun circuit is made of laser tube LD, pulse emission ic chip 1, triode T1, diode D1～D4, resistance R 1～R2, capacitor C 1～C5, K switch 1 and gunlock button AN, the colelctor electrode of the negative pole of laser tube LD and triode T1 joins, the base stage of triode T1 is joined by 1 pin of resistance R 1 with ic chip 1,2 pin of ic chip 1 join with resistance R 2,

capacitor C
