Described signal input mechanism 2 comprises: the first induction lever 21, the second induction lever 22, elastic reset spare 23, signal contact head 221 and five metals shell fragment 222, the end of the described first induction lever 21 and the second induction lever 22 is hinged, and elastic reset spare 23 is arranged on both hinged places, described signal contact head 221 is arranged on the second induction lever, 22 other ends, and 222 on described five metals shell fragment is arranged on the signal contact head 221; Described identification circuit 3 comprises the plurality of touch points 31 that distributes on a pcb board 32 and the pcb board 32; Described automatic coin-feeding mechanism 4 comprises a rotation coin dish 41, drives the propulsion system 42 of described rotation coin dish 41 rotations, supports the leakage coin dish 43 that described rotation coin dish 41 rotates, and forms between described rotation coin dish 41 and the described leakage coin dish 43 and the passage of going into 1 perforation of coin mouth.Described rotation coin dish 41 bottoms are provided with at least one coin dropping hole 411, on the bottom surface of described rotation coin dish 41, a side of described coin dropping hole 411 also is provided with the corresponding projection 412 of quantity and described coin dropping hole 411.

Like this, because having with described, the automatic coin-feeding mechanism 4 of present embodiment goes into the passage that coin mouth 1 connects, in the time of on a plurality of coins to be identified being placed rotation coin dish 41, rotation coin dish 41 rotates under the driving of propulsion system 42, coin to be identified can spill one by one from coin dropping hole 411, and under the promotion of projection 412, enter into into coin mouth 1, the coin to be identified of different size is being gone into coin mouth 1 place by 2 identifications of signal input mechanism, produce different signals and pass to identification circuit 3, can finish identification coin value.

In conjunction with the accompanying drawings 1 and accompanying drawing 2, quantity the best of described coin dropping hole 411 and projection 412 is 5, and distributes around the center equal angles of described rotation coin dish 41.Certainly, the quantity of coin dropping hole 411 and projection 412 can also be for a plurality of.Coin enters coin dropping hole 411 for convenience, is provided with a ring-type inclined-plane 413 around each coin dropping hole 411.In order to prevent that two coins from overlaping, enter into described coin dropping hole 411 simultaneously, the thickness at described coin dropping hole 411 edges is less than the thickness for the treatment of ungenerously the identification coin most.In like manner, enter into coin dropping hole 411 side by side together in order to prevent two coins, the diameter of described coin dropping hole 411 greater than the diameter of maximum coin to be identified less than the twice of the diameter of minimum coin to be identified.

In the present embodiment, described leakage coin dish 43 middle parts are provided with annular recess 431, the annular projection 414 that the position is provided with and it coincide of rotation coin dish 41 corresponding described annular recess 431, rotation coin dish 41 and leakage coin dish 43 are articulated by annular recess 431 and annular projection 414.Described leakage coin dish 43 at the circumferential position of the described rotation coin of correspondence dish 41 around being provided with surrounding edge 432.

Break away from rotation coin dish 41 when rotated for fear of coin, coin-feeding mechanism 4 comprises that also one fixedlys connected with described surrounding edge 432 and is covered in the shell 5 of described rotation coin dish 41 tops automatically, and described shell 5 middle parts are provided with opening 51.

Described rotation coin dish 41 and leak between the coin dish 43 distance near the position of going into coin mouth 1 greater than both distances between other positions, for rotation coin dish 41 on projection 412 adaptive, described leakage coin dish 43 corresponding described protruding 412 positions are provided with chute 433.Like this, if coin has promptly entered in the coin dropping hole 411 in the position that does not move near going into coin mouth 1, coin can continue to move ahead under the promotion of coin dropping hole 411, when coin moves to when going into the position of coin mouth 1, enter into the passage between described rotation coin dish 41 and the leakage coin dish 43, because rotation coin dish 41 is rotated further under the driving of propulsion system 42, projection 412 can continue the coin that enters into passage to carry out, and it is entered into into coin mouth 1.

Described leakage coin dish 43 comprises master 434 and the support plate 435 that is fixed together; The input end of signal input mechanism 2 extends to the side into coin mouth 1, and it comprises being arranged on into first of coin mouth 1 end responds to lever 21 and the second induction lever 22 hinged with its hinge, is provided with an elastic reset spare 23 in both hinged places; Be provided with induction contact 211 in the first induction lever, 21 ends, described induction contact 211 directly contacts the coin at coin mouth 1 place, when coin passes through from going into coin mouth 1, extruding induction contact 211, driving the first induction lever 21 rotates, the elastic reset member 23 that is fixed on the first induction lever 21 and the second induction lever, 22 hinge junctions is subjected to 21 twistings of the first induction lever, drive the second induction lever 22 and rotate the transmission rotation displacement to the second induction lever 22, the second induction lever, 22 1 ends are provided with signal contact head 221, five metals shell fragment 222 is being set on the signal contact head 221 and is turning round the torsion spring 223 that is pressed on the five metals shell fragment 222, the effect of torsion spring 223 is to compress five metals shell fragment 222, avoid the elastic break-down of five metals shell fragment 222, five metals shell fragment 222 moves under the drive of the second induction lever 22, contact with the contact point 31 of diverse location on the pcb board 32, finish the conversion transmission from the displacement signal to the electric signal.

Because the difference in size of the diameter of some different denominations coin is small, in order to differentiate these fine distinctions more accurately, the described second induction lever, 22 length are greater than the length of the first induction lever 21, the former length is approximately 3-4 times of the latter, and signal input mechanism 2 just can well detect the result that coin diameter to be measured and amplification detection arrive.

With reference to Fig. 3 as seen, identification circuit 3 comprise be fixed in a plurality of on the pcb board 32 along line spread contact point 31 and prestore coin dimensions information (coin that can be any country or area also can be other non-currency but game money etc.) and judge the IC of coin currency value according to this with coin profile, the quantity of contact point 31 is many more, and its coin that can discern different-diameter is just many more.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
