Embodiment
Device of the present utility model can be that game machine, telephone set, multifunction timepiece and other have the device of LCD.
Extremely shown in Figure 6 as Fig. 1 is the principle and the structural representation of a game machine preferred embodiment of the present utility model.Its principle as shown in Figure 1, the right is the circuit board 1 that is contained in the casing among the figure, the left side is external liquid crystal display card 2.
Introduce the assembly on the circuit board below earlier, on circuit board, be provided with microprocessor 12, the IC11 that is connected with microprocessor, button 13, show contact (golden finger) 14, conductive rubber strip 15, mate switch 16, loudspeaker 17, supplying cell 18 and external power supply jack 19.Wherein can store dozens or even hundreds of game shows in the IC11; Conductive rubber 15 and coupling switch 16 are formed interface circuit, can realize being electrically connected with the plurality of liquid crystals display card 2 of different display effects.
After liquid crystal display card 2 being inserted in the display window of casing, show that signal that contact 14 is exported can output to the pin of LCD21 by conductive rubber strip 15; Simultaneously the triggering part 25 of liquid crystal display card cooperates with coupling switch 16, selects signal to the corresponding Display Category of microprocessor 12 outputs, with among the selection activation IC with the corresponding game shows of this liquid crystal display Card Type.Suppose to have among the IC 100 game shows, and wherein 10 needed display effects of program are corresponding with this liquid crystal display card, then these 10 programs are activated, and this moment, the user can select in these 10 programs any to play by button 13.That is to say, the liquid crystal display card of different display effects can activate different game shows, because the LCD cost difference of different display effects is bigger, when the user will play low-grade the recreation, only need the lower liquid crystal display card of purchase cost, when playing high-grade the recreation, then need the higher liquid crystal display card of purchase cost.
In an embodiment of the present utility model, the structure of game machine is shown in Fig. 2,3,4.As can be seen from Figure 4, wherein LCD21 is contained in the plastics housing 22, forms liquid crystal display card 2, is provided with buckle 23 on the top of housing, the bottom is provided with two bayonet locks 24.As can be seen from Figure 3, the bottom of casing is control button 13, top is the display window that is used for the plug-in mounting liquid crystal display card, circuit board 1 is fixedly mounted in the casing 3, from being installed, window can see the part of circuit board 1, comprise conductive rubber strip 15 and contact formula switch 16, install window above be provided with snap seats 31, below be provided with bayonet lock slot 32.As can be seen from Figure 2, after liquid crystal display card is inserted on the main frame, snap seats 31 on the casing, bayonet socket 32 cooperate with buckle 23 and bayonet lock 24 on the liquid crystal display card housing respectively, liquid crystal display card can be fixed, when needs are changed, liquid crystal display card can be taken off by stirring snap seats 31.
Shown in Fig. 5,6, adopt contact formula switch to finish the display type coupling in the present embodiment, as can be seen from Figure 3, wherein circuit board is provided with 5 contact formula switches, and 25 powers totally 32 kinds of assembled state can be arranged; The housing back of liquid crystal display card is provided with one or more salient points that cooperate with these contact formula switches, and these salient points are just formed the triggering part 25 of liquid crystal display card.With one of them contact switches is example, and as can be seen from Figure 5, when not packing liquid crystal display card into, contact switches 16 is in normally off; After loading onto liquid crystal display card, the salient point 25 on the housing is depressed contact and is made it transfer off-state to by normally off, thereby imports a coded signal.By different salient points is set, can import different coded signals.In the utility model, the implementation of coupling switch 16 is not limited to the foregoing description, and for example wherein contact can be made as normally open, just becomes closure state when being depressed by salient point; Concave point also can be set on housing make it to cooperate, can also be designed to alternate manner certainly with contact.
The foregoing description is by selecting the different liquid crystal display card of pegging graft on a main frame, each liquid crystal display card can activate one or more game shows of same Display Category, make low-grade game machine accomplish that really a multi-function device can be equipped with Different L CD card according to program, realize Polymera recreation cheaply or multi-functional.
When the utility model was implemented on device such as telephone set or multifunction timepiece, it realized that principle is identical with game machine in the foregoing description, was that aspects such as device on content displayed, the circuit board are distinguished to some extent, illustrated no longer one by one herein.
