Abstract
The utility model relates to a photoelectric induction device for table games. The utility model is provided with an optical coupling control circuit. The utility model is characterized in that the utility model is provided with at least one set of optical couplers; each optical coupler is composed of an infrared photoluminescence diode and an infrared receiving photoelectric crystal; the high and the low potential of the output terminal can be controlled according to the on and off signals of the infrared photoluminescence diode and the infrared receiving photoelectric crystal. Because of the photoelectric induced structure, the failure rate is decreased, the operating sensitivity is increased, the utility model is suitable for machine tables with two holes, six holes or the other machine table for the simple circuit, the production is convenient, and the cost can be reduced.
Description
The utility model relates to a kind of photoelectric induction device of Board Game, particularly relates to a kind of input structure with optically-coupled control circuit, is suitable for being applied in the photoelectric induction device of the Board Game board of two holes, six holes or other classes.
Commonly use the table of game player of desktop Hockey (hockey) and Foot ball (football), its induction mode uses microswitch to come control signal, but this microswitch is in regular pushing in the process, quite easy fault, once fault must be changed microswitch voluntarily, thereby cause user's puzzlement.Especially when six hole boards, microswitch quantity is many, fault rate is high, so quite undesirable.
Main purpose of the present utility model is to provide the photoelectric induction device that a kind of fault rate is low, control sensitive Board Game; Secondary objective of the present utility model is to provide a kind of circuit design simple and applicable to the photoelectric induction device of the Board Game of two, six holes or other boards; Another purpose of the present utility model is to provide one to produce conveniently and the photoelectric induction device of the Board Game that can reduce production costs.
The purpose of this utility model is achieved in that a kind of photoelectric induction device of Board Game, wherein include an optically-coupled control circuit, be provided with one group in the described optically-coupled control circuit at least and look the photo-coupler whether its two signal interrupting comes the high electronegative potential of control output end.
The photoelectric induction device of Board Game of the present utility model, wherein this photo-coupler is that infrared light-emitting diode and infrared ray receive photoelectric crystal.
The photoelectric induction device of the Board Game that the utility model provides, with the optically-coupled control circuit, whether detect its signal interrupting, the height of control output end (high), low (low) current potential, utilize the structure of optoelectronic induction to reduce fault rate, promote the sensitivity of controlling, and circuit simply is applicable to the Board Game board of two holes, six holes or other classes, and not only convenient side produces and can reduce production cost, has reached purpose of design fully.
Below sincerely by the explanation of preferred embodiment conjunction with figs. so that structure of the present utility model and characteristics are done a detailed elaboration.
Fig. 1 shows the first preferred embodiment circuit diagram of the present utility model.
Fig. 2 shows the second preferred embodiment circuit diagram of the present utility model.
Fig. 1 shows the first preferred embodiment circuit diagram of the present utility model.As shown in Figure 1, optically-coupled control circuit 1 of the present utility model, mainly by R1, R2, three resistance 10 of R3,11,12, photo-couplers (D1 infrared light-emitting diode 13 (IRLED) and a Q1 infrared ray receive photoelectric crystal 14), D2 diode 15, Q2 triode 16 and a P11 (P12) output 17 are formed; After connecting system voltage, D1 infrared light-emitting diode 13 is launched infrared ray through R1 current-limiting resistance 10, this moment, the Q1 infrared ray received photoelectric crystal 14 at the photoelectric current that is being hidden reception D1 infrared light-emitting diode 13 under the worn-out situation, Q2 triode 16 is blocked, and P11 (p12) output 17 is filled to height (high) current potential of 4V, otherwise, be subjected to hiding worn-out if D1 infrared light-emitting diode 13 and Q1 infrared ray receive 14 of photoelectric crystals, 16 conductings of Q2 triode, 17 of P11 (P12) outputs are the saturation voltage 0.2V (low current potential) of Q2.
Fig. 2 shows the second preferred embodiment circuit diagram of the present utility model.As shown in Figure 2, by three R4, R5,20,21,22, three groups of photo-coupler (three D3 of R6 resistance, D4, D5) infrared light-emitting diode 23,24,25 and three Q3, Q4, the Q5 infrared ray receives photoelectric crystal 26,27,28), D6 diode 29, Q6 triode 30 and a P13 (P14) output 17 form; It increases to three groups with photo-coupler, and be applicable to six hole boards, this D3 wherein, D4, D5 infrared light-emitting diode 23,24,25 and Q3, Q4, the Q5 infrared ray receives photoelectric crystal 26,27,28 are of a pair, work as D3, D4, D5 infrared light-emitting diode 23,24,25 light is incident upon Q3, Q4, the Q5 infrared ray receives photoelectric crystal 26,27,28 o'clock, P13 (P14) is filled to 3～4V and (looks D3, Q3, D4, Q4 and D5, whether the angle of Q5 aims at variant slightly), otherwise, as long as three pairs of emissions receive any a pair of blocking arranged, P13 (P14) output 31 is at once to about the 1.5V.Therefore when six hole boards, the high and low voltage of output is 3V and 1.5V, outputs to when VCC voltage is 5V, and the micro computer of Vtb (thresh hold)=2V just can meet its standard.
In sum, the photoelectric induction device of Board Game of the present utility model, whether signal interrupting by photo-coupler, come the height (high) of control output end, low (low) current potential, thereby reduce fault rate, promote the sensitivity of controlling, and circuit simply is applicable to the Board Game board of two holes, six holes or other classes, and convenience is produced and can be reduced production costs.
