Embodiment

The utility model specific embodiment includes the rotary case in the foundation mass 10 of the lower section of hopper 9, it is characterised in that：（1) rotary case with several coin capture plates 12 and affixed coin whereabouts stop bit bearing plate 13 thereunder for capturing hole 11 along the uniform coin of rotary case circumferencial direction by constituting；（2) there is the coin-out gap 14 led on the outside of rotary case between the bottom surface of coin capture plate and the upper surface of bearing plate and coin guide way 15 is pushed away;(3) rotary case described in is located above foundation mass, offered on the bearing plate of described rotating disk position hard provided with the bottommost that the convex body 17 of annular port moved with rotary case to block in coin capture hole is passed down through at annular port 16, foundation mass correspondence coin discharge Coin makes it along coin-out gap 14 and pushes away the guiding work of coin guide way 15 and discharged towards coin discharge.

Above-mentioned pushes away coin guide way 15 between two adjacent coins capture bottom hole end, and the guiding working face that this pushes away coin guide way is curved, and rotary case outer circumference face is extended to rotary case outer rim against rotation direction from close to rotary case medium position.

5 above-mentioned rotary case centers are connected with the motor-driven mechanism 18 on foundation mass, and the described Jian on coin guide way that pushes away is provided with opening towards the conduit 19 of the annular port of bearing plate, passes through when being rotated with sharp rotary case from the convex body on foundation mass.

In order that coin can be smoothly discharged out, above-mentioned coin-out gap and the thickness of a coin is adapted.During coin-out, when coin does not fall into coin capture bottom hole portion correctly and can not skidded off from coin-out gap, rotary case is blocked in meeting 10, therefore above-mentioned convex body bottom side is hinged in the vallecular cavity 20 of foundation mass, and vallecular cavity bottom is provided with the back-moving spring 21 for acting on convex body following side.When there is clogging in coin-out gap, convex body compression reseting spring 21 under the promotion of coin reaction force, its own rotates resigning around with the pin joint of foundation mass, releases the barrier effect of the coin captured to the coin in hole, rotary case is rotated further（As shown in figure 8, arrow show rotary case traffic direction in figure, 22 is fail the coin fallen on completely on coin capture bottom hole portion bearing plate,）So as to avoid the phenomenon of rotary case stuck 15.

In work, in order that diameter differs the larger reliable coin-out of different denominations coin energy, the resistance coin working face of convex body should be wider, but this convex body operation conduit 19 for causing to push away on coin guide way simultaneously again is also wider, it is also easy to produce phenomenon of the minor diameter coin card in conduit, groove 23 is thus provided with the top of above-mentioned convex body, the opening for pushing away coin guide way is provided with the anti-sticking coin block 24 being located above convex body groove towards the conduit of the annular port of bearing plate.

Z0 reduces coin capture hole plug probability to improve coin capture rate, and the upper surface of above-mentioned rotary case is high in outer rim, the low inverted cone surface of central part, so as to solve the contradiction of rotary case inclination angle and coin capture rate（Inclination angle is small, is conducive to the sixth of the twelve Earthly Branches to fall into coin capture hole through the coin on rotary case working face that lies low, but is unfavorable for upright coin change posture, and inclination angle is big, then on the contrary）.In order that coin is easier to by coin capture hole capture, hole top edge is captured towards the front side of rotation direction provided with coin capture importing skewed slot 25 in coin, rear side overflows skewed slot 26 provided with coin, enable to fail ^5 and correctly lie low to capture the coin in hole in coin and overflows in rotary case rotary course, in case blocking coin captures hole.
