The present invention relates to a coin motorized selector for sorting by rolling the input coin. In particular, the present invention relates to coin operated selectors used in game machines such as pachinko slots, ie pinball-style slot machines. Moreover, of course, the term "coin" of this specification includes hardening of the small disk shape which is currency. In addition, the term "coin" of this specification includes, of course, a disk-shaped medal or a token used in a game or the like.

Various coin electric selectors are used in medal game machines and pinball style slot machines. For example, said selector is disclosed by Unexamined-Japanese-Patent No. 6-25963 (real element 4-23240) by this applicant. 7 schematically shows a coin powered selector disclosed in Japanese Patent Application Laid-Open No. 6-25963. In addition, Patent Application No. 4-23240 adds that constitutes US Patent No. 5,293,981.

Fig. 13A is a schematic perspective view of the entire selector from almost the upper left. Fig. 13B is a schematic cross-sectional view of the selector viewed from the side. The selector in Fig. 13A has a long and large main body frame 4 laterally. Attached pieces 19 and 18 are formed at each end of the main body frame 4, respectively. By means of these attachment pieces 19 and 18, the body frame 4 is fixed to the whole in a pinball-style slot machine. That is, the main body frame 4 is inclined in the longitudinal direction with respect to the horizontal plane, and is also fixed inclined in the width direction (see FIG. 13 (B)).

A slightly larger rectangular window 9 is opened below the central portion of the main body frame 4. On the upper edge of this window 9, a horizontally long rectangular thin coin guide 10 is fixed (see Fig. 13 (B)). In addition, a pivot shaft 8 is attached to the main body frame 4 above the coin guide 10. A curved small plate arm 11 is rotatably attached to this pivot shaft 8. That is, the lower half of the plate arm 11 is made accessible in the window 9. The pistol-shaped thing shown in the left half part of FIG. 13 (A) is the door plate 5.

The door plate 5 is rotatably attached to the pivot shaft 8 above the main body frame 4 via a spring (not shown). That is, the door plate 5 and the plate arm 11 can be integrally rotated using the pivot shaft 8 and the spring (not shown). Therefore, the door plate 5 also moves only by moving the plate arm 11. The upper ends of the main body frame 4 and the door plate 5 are each bent outward and are formed in the coin inlet 1 (see Fig. 13A). The substantially rectangular one shown in the right half of Fig. 13A is the cover plate 17. A small columnar solenoid 16 is disposed on the cover plate 17.

The solenoid 16 is supported on the pivot shaft 14 from above by a cover plate 15 curved in an L shape. Accordingly, the drop hole 12 of the thin and long coin is opened and closed by turning the solenoid 16 on and off. In addition, the code | symbol 13 shown at the right end part of FIG. 13A is a lid part, and is formed by a part of cover plate 17. As shown in FIG. By the lid 13 and the main body frame 4, an elongated coin outlet 2 is formed. By the way, in the conventional coin-operated selector described above, coins are injected into the inlet 1.

The coin entered falls while rolling the rail 7 formed in the lower edge of the main body frame 4 (refer FIG. 13 (B)). When the coin A which drives the rail 7 is genuine, the coin guide 10 and the door board 5 are guided, and the rolling can continue further. When the coin which drives the rail 7 is not genuine and its diameter is small, it will fall out of the coin guide 10 or the door board 5, and fall. When the coin which drives the rail 7 is not real and its diameter is large, it stops by the attachment plate 101 of the coin guide 10, etc. In this case, for example, when the door plate 5 moves against a spring (not shown), the plate arm 11 also moves.

As a result, the coins stopped by the attachment plate 101 or the like fall by the plate arms 11. However, there is a problem that the coin-operated selector described above is large in the lateral direction. Moreover, when attaching, there existed a problem that attachment space was large in order to obliquely whole the selector. Moreover, when changing the size of the coins to be sorted, there is a problem that the selector must be completely modified.

The present invention was developed from the object of solving the above problems. That is, the present invention was developed from the object of making the size of the entire selector as small as possible. In other words, the present invention has been developed from the object of making it possible to attach the entire selector vertically without obliquely. In addition, the present invention was developed from the object of making it easy to change the diameter size of the sorting coin. In addition, the present invention has been developed from the object of adding a function of a coin electric selector.

The present invention is characterized by comprising at least an arc-shaped passage means for driving the coin input by the peripheral edge and a groove means having a substantially cross-section for guiding the upper edge of the coin for driving the passage means. It is a coin powered selector.

The present invention is also a coin powered selector, wherein the groove means is formed by a pair of rotatable rollers.

In addition, the present invention is a coin powered selector, characterized in that the roller means is driven to rotate.

In addition, the present invention is a coin electric selector, characterized in that the groove means is movable to a position corresponding to the passage means.

Moreover, this invention is a coin electric selector characterized by the said groove means comprised by the rotatable roller.

(First Embodiment of the Invention)

EMBODIMENT OF THE INVENTION Below, this invention is demonstrated, referring an accompanying drawing about 1st Example.

1 is a perspective view from below schematically showing a first embodiment according to the present invention. 2 is a front view of FIG. 1. 3 is a schematic perspective view of a portion of FIG. 1. 4 is a front view of FIG. 3. FIG. 5 is a schematic cross-sectional view of FIG. 2 viewed from the line A-A. FIG. In addition, the coin C of FIG. 5 is added for description. 6 is a schematic cross-sectional view of FIG. 2 from below;

The coin motorized selector of the first embodiment of the present invention has a transversely long, almost right triangle with a whole thickness (see Fig. 1). The selector of this embodiment is installed such that the longest side of the right triangle is next to the longest side (see FIG. 2).

In the selector, coins are injected from the upper acute portion and driven toward the lower acute portion. That is, coins are injected from the opening 21 formed at the top of the selector. The coin injected from the opening 21 is guided by the circular arc path 22 which becomes a circle of about 1/4. The arc passage 22 is formed of a slightly thick plate 23 having a bird-like shape. Each side of the plate 23 of the new shape is sandwiched by a large body frame 25 and a slightly smaller door 31. The door 31 is attached to the main body frame 25 so as to be openable and closeable by a pair of pivot shafts 32 located above.

Near the top of the main body frame 25, a doll-shaped slightly larger window 27 is opened. And the shielding piece 28 of the outward direction is formed in the edge of the window 27 near the arc path 22. As shown in FIG. The arm piece 51 is formed in the lower half part of the long side part of the main body frame 25 at the outer side. This arm piece 51 is bent further downward and the pivot shaft 52 is fixed to the upper end part. The pivot shaft 52 protrudes toward the door 31. First, the pivot shaft 52 is rotatably enclosed with a roller 53 having a groove in the center of the front circumference circumferential surface (see FIGS. 5 and 6). Further, a roller 55 having a taper on the side surface is rotatably mounted on the pivot shaft 52. In this case, the tapered surface of the roller 55 is faced against the grooved roller 53.

Therefore, the pair of rollers 53 and 55 form a small hole 56 having a V-shaped cross section (see FIGS. 5 and 6). Moreover, the roller 55 is lightly pressed by the spring 57 external to the pivot shaft 52. The spring 57 is for example supported by a plug 58 in the cylindrical portion 59 of the door 31. The small rectangular body in the arm 51 is the solenoid 61. The plunger of the solenoid 61 is pivotally supported by the long L-shaped operation piece 63 via the elliptical small link 62 (refer FIG. 6). And a slightly long rod 65 is fixed to the lower surface of the front end of the operation piece 63. The tip of the rod 65 is slidably inserted into the groove of the roller 53.

Therefore, for example, when solenoid 61 of normally on is turned off, it rotates about the pivot axis of the center of L-shaped operation piece 63. FIG. As a result, the tip of the rod 65 falls from the roller 55. In other words, the roller 53 falls from the roller 55 through the groove. Further, under the arc passage 22, a long roller rail 20 is rotatably arranged.

(First embodiment)

The coin motorized selector of this embodiment which consists of the above structure is used in the state shown in FIG. 5 and FIG. In other words, the pair of rollers 53 and 55 are used in a state where a small groove 56 having a V-shaped cross section is formed.

In this state, when the coin C to be sorted is put into the opening 21, the coin C is guided by the arc passage 22 to be driven (see Fig. 4). In the case where the coin C is genuine, in other words, when the coin C is selected, the coin C passes through the arc passage 22. That is, the lower edge of the coin C is guided by the circular arc passage 22, and the upper edge of the coin C is guided by the small grooves 56 of the pair of rollers 53 and 55. Therefore, when the coin C is genuine, that is, when the coin is sorted, the coin C smoothly passes through the arc passage 22 and is driven further downward. In this case, since the pair of rollers 53 and 55 are rotatable, the real coins C pass smoothly and quickly.

Therefore, it is a matter of course that the spring 57 has a weak elastic force. It goes without saying that the roller may be rotated by, for example, a small electric motor (not shown). In this case, it is necessary to make the pivot shaft 52 rotatable, for example. In addition, when the rollers 53 and 55 are rotated, the passage speed of the coin C is of course high. If the coin put into the opening 21 is not genuine, for example, if the coin has a small diameter, it does not pass through the arc passage 22. That is, the lower edge of the coin is guided by the arc passage 22, but the upper edge of the coin is not guided by the small grooves 56 of the pair of rollers 53 and 55.

In addition, if a small coin is vibrated, the outer diameter becomes large and becomes like a real coin. In this case, the spring 57 acts, in other words, the spring 57 absorbs the vibration of the coin. Thus, when the diameter of a coin is small, it will fall out of a pair of rollers 53 and 55 and fall downward. If the coin put into the opening 21 is not genuine, for example, even if the coin is large in diameter, it does not pass through the arc passage 22. That is, the lower edge of the coin is guided by the arc passage 22, but the upper edge of the coin is brought into contact with the pair of rollers 53 and 55 to be stopped.

In other words, when the diameter of the coin is large, the coin is interposed between the arc passage 22 and the pair of rollers 53 and 55 and cannot move. In this case, by opening and closing the door 31 to the pivot axis center, it is possible to simply drop a large coin downward. In addition, when the solenoid 61 is operated, the roller 53 is moved, so that a coin having a large diameter falls downward. In addition, in the present embodiment, a small groove 56 having a V-shaped cross section is formed by the pair of rollers 53 and 55. However, as seen from the arc passage 22, the small groove 56 is of course U-shaped in cross section.

Further, since the cross-sectional shape may be a U-shaped small groove 56, of course, the small groove 56 may be formed in another member, for example, one roller or semi-circular plate shape. Furthermore, the cross-sectional shape of the small grooves 56 is exactly one inclined surface in the present embodiment, but of course two are good. In addition, in the case of changing the diameter of the real coin (C) of the present embodiment, it is a matter of course that only the roller 53 or the roller 55 or a pair of rollers can be replaced. Moreover, the narrow connection part of the pair of rollers 53 and 55 is circumferential in order to prevent a pass other than a genuine coin even if the pair of rollers 53 and 55 fall.

(2nd embodiment of invention)

EMBODIMENT OF THE INVENTION Below, this invention is demonstrated, referring an accompanying drawing about 2nd Example.

7 is a perspective view schematically showing a second embodiment according to the present invention. 8 is a front view of FIG. 7. FIG. 9 is a schematic perspective view of FIG. 7 viewed from above the inclination. 10 is a rear view of FIG. 7. FIG. 11 is a partial view showing a part where main parts of FIG. 10 are removed. FIG. 12 is a front view showing a portion of FIG. 8 removed. FIG. In the coin-operated selector of the second embodiment of the present invention, the entire outline is formed in a laterally long box shape (see FIG. 7). In addition, the selector of this embodiment is formed in the shape in which the whole box was inclined downward (refer FIG. 8).

At the time of use of the selector, coins are introduced from the upper acute angle portion and driven toward the lower acute angle portion (see FIG. 12). First, coins are introduced from the opening 221 formed at the top of the selector. The coin injected from the opening 221 is guided by the arc path 222 which becomes about 1/4 round. The arc passage 222 is formed by a slightly thick plate 223 having a crane-like shape (see FIG. 12). And the crane shaped plate 223 is fixed to the large main body frame 225 (refer FIG. 12). Furthermore, the crane-shaped plate 223 is covered by a slightly smaller door body 231 (see Fig. 11).

The door body 231 is formed of a substantially pentagram-shaped resin molded article and an L-shaped metal plate 231M. In addition, the door body 231 is attached to the main body frame 225 so that it can be opened and closed by the pivot shaft 232 in the upper center. Near the top of the main frame 225, an ax-shaped slightly larger window 227 is opened (see FIG. 12). The crescent-shaped opening and closing plate 226 is supported by the pivot shaft 228 via an approximately Y-shaped arm plate 229 at the edge of the window 227 near the arc passage 222 (Fig. 10). Reference). The opening and closing plate 226 and the arm plate 229 is for canceling by removing coins accumulated in the passage as described later.

Moreover, the operation piece 224 for opening and closing the door body 231 is formed in the outer end part of which the arm plate 229 is long (refer FIG. 10). It goes without saying that the operation piece 224 can penetrate the body frame 225. A slightly larger arm 251 is formed on the outside in the center of the upper edge of the body frame 225. The arm 251 is bent further downward, and a protruding shaft 252 is fixed to the tip portion thereof (see FIG. 10). The protruding shaft 252 protrudes toward the door 231. The roller 253 is rotatably mounted on the protruding shaft 252 via a spacer. Grooves 255 are formed in the entire base end of the roller 253 (see FIG. 9).

The groove 255 is for sliding the roller 253 in the protruding axis 252 direction as described later. Furthermore, the groove 256 is formed in the front circumference of the roller 253. This groove 256 is for guiding the upper edge of the coin to be driven as described later. One of the side surfaces of the groove 256 is formed as an inclined surface. In other words, the roller 253 is formed with a groove 256 having a substantially V-shaped cross section. As shown in the right part of FIG. 11, the J-shaped pressing piece 233 is supported by the pivot shaft 235 and suspended on the upper part of the door body 231. As shown in FIG.

In addition, the pressing piece 233 penetrates the door body 231 so as to oscillate, and presses the coin passing through the main body frame 225. Therefore, the small spring 236 is arrange | positioned between the door body 231 and the pressing piece 233 (refer FIG. 11). Furthermore, a g-shaped stopper piece 237 is supported and suspended on the upper portion of the door body 231 by the pivot shaft 235. The stopper piece 237 penetrates the door body 231 so as to be able to swing. And the passage of the coin coming from the circular arc path 222 is prevented by the lower end part of the stopper piece 237 (refer FIG. 12). The small rectangle shown in the upper left of FIG. 10 is the solenoid 261 in the arm 251.

An elliptical small link (not shown) is pivotally supported by the plunger (not shown) of the solenoid 261. Furthermore, L-shaped links (not shown) are pivotally supported on the small links. And the long spring piece 263 is supported by the L-shaped link by the pivot shaft 262 (refer FIG. 9). A slightly longer rod 265 is fixed to the lower surface of the front end of the spring piece 263. The tip of the rod 265 is slidably inserted into the groove 256 of the roller 253 described above (see FIG. 9). Therefore, when solenoid 261 is turned on, spring piece 263 is rotated about pivot axis 262.

As a result, the rod 265 moves and the roller 253 approaches the door 231 as shown by the arrow of FIG. In other words, the groove 256 of the roller 253 for guiding the coin corresponds to the arc passage 222. On the other hand, when the roller 253 approaches the door body 231, the protrusion 239 of the stopper piece 237 is pressed by the roller 253 (refer FIG. 8). Therefore, since the lower end part of the stopper piece 237 is pulled in, the coin from the circular arc path 222 is made to roll further (refer FIG. 12). In other words, the coin from the arc passage 222 drives the fixed rail 271 of the main frame 225.

In addition, three sensors S for counting are arranged near the fixed rail 271. The sensor S detects, for example, magnetically or optically the coin passing through the fixed rail 271. In addition, the number of the sensors S is set to three in order to prevent the malfunction by the mischief. The slightly larger rectangle shown on the left side of FIG. 10 is also a solenoid 272. The plunger of the solenoid 272 is arrange | positioned rotatably by the U-shaped movable rail 273 via the shaft 279 (refer FIG. 10). That is, the upper end of each of the U-shaped movable rails 273 is supported by the pivot shaft 277 by the main body frame 225.

A pair of inclined holes are opened in the central portion of the movable rail 273 to penetrate the shaft 279 (see FIG. 9). Moreover, the stopper 275 is formed in the movable rail 273 via the arm piece. When the solenoid 272 is off, the movable rail 273 is located outside the main frame 225. The stopper 275 is located inside the main body frame 225. That is, when the solenoid 272 is off, the coin coming from the fixed rail 271 is blocked by the stopper 275 and falls in the safe (not shown) (refer FIG. 12). When the solenoid 272 is turned on, the movable rail 273 is located inside the body frame 225.

The stopper 275 is located outside the main body frame 225. Therefore, when the solenoid 272 is turned on, the coin is guided to the main body frame 225 by falling on the movable rail 273 (see Fig. 7). Coins guided to the main frame 225 and falling down are stored in, for example, a tank (not shown) of the hopper. In addition, the small circle shown in the substantially center of FIG. 11 is the steel sphere 291 for coin passage adjustment. The steel ball 291 is rotatable and is arranged to be accessible to the body frame 225. That is, the steel ball 291 is for adjusting the width of the arc passage 222 in accordance with the thickness of the coin injected into the opening 221.

(Second embodiment)

The coin motorized selector of the second embodiment having the above-described configuration is usually used with solenoids 261 and 272 on. In other words, the groove 256 of the roller 253 corresponds to the position of the arc passage 222. And the movable rail 273 is located inside the main body frame 225. Moreover, of course, the stopper piece 237 is located outside the door body 231, and the stopper 275 is located outside the main body frame 225. As shown in FIG. In this state, when a coin is thrown into the opening 221, the coin is guided by the arc passage 222 and falls electrically.

In other words, if the coin is real, in other words, if the coin is a selected coin, it exits the arc passage 222. That is, the lower edge of the coin is guided by the arc passage 222 and the upper edge of the coin is guided by the groove 256. Therefore, if the coin is genuine, it passes smoothly through the circular arc path 222 and is to be transmitted further downward. In this case, since the roller 253 is rotatable, the real coins pass smoothly and quickly. Therefore, it is a matter of course that the spring 236 has a weak elastic force.

It goes without saying that the roller 253 may be rotated by, for example, a small electric motor (not shown). In this case, for example, the pivot shaft 252 needs to have a rotatable attachment structure. In addition, when the roller 253 is driven to rotate, of course, the passage speed of the coin is increased. If the coin put into the opening 221 is not genuine and has a small diameter, the coin has not passed through the arc passage 222. In this case, the lower edge of the coin is guided by the arc passage 222, but the upper edge of the coin is not guided by the groove 256.

Therefore, the coin having a smaller diameter is inclined, for example, to fall inside the door body 231 and be canceled. In addition, even if the coin is small in diameter, if it oscillates, it is apparent that the diameter is large and becomes like a real coin. In this case, the spring 236 acts to absorb the vibration of the coin. Therefore, when the diameter of a coin is small, it will be canceled away from the groove | channel 256 of the roller 253. FIG. Even if the coin put into the opening 221 is not genuine and has a large diameter, the coin has not passed through the arc passage 222.

The lower edge of the coin is guided by the arc passage 222, but the upper edge of the coin is in contact with the roller 253. In other words, when the diameter of the coin is large, it is held between the circular arc path 222 and the roller 253 and cannot move. In this case, by opening and closing the arm plate 229 at the pivot axis 228 center, a coin with a large diameter can be easily dropped and canceled. In other words, the door 231 is opened and closed through the operation piece 224 at the same time as the opening and closing plate 226 moves by the operation of the arm plate 229. In the present embodiment, the grooves 256 having a substantially V-shaped cross section are formed in the roller 253. In other words, when viewed from the arc passage 222, the groove 256 is U-shaped in cross section.

Furthermore, since the groove 256 having a U-shaped cross section may be used, it is a matter of course that the groove 256 may be formed by, for example, two rollers. It is a matter of course that the groove 256 may be formed in another member, for example, a semi-circular plate shape. Furthermore, the cross-sectional shape of the grooves 256 is exactly one inclined surface in the present embodiment, but of course, may be two. In addition, when changing a selection coin in this Example, it can carry out only by replacing the roller 253. FIG. For example, when changing the diameter of a selection coin, of course, it can carry out by replacement of the roller 253.

Moreover, of course, even when changing the thickness of a selection coin, it can be performed by replacing the roller 253. In this embodiment, the solenoids 261 and 272 are usually turned on and used respectively. However, as is apparent from the above description, the solenoid 261 can be turned on and the solenoid 272 can be turned off. For example, the solenoids 261 and 272 are turned on respectively to use a first safe (not shown). And when the 1st vault becomes full, the solenoid 272 can be turned off and a 2nd vault (not shown) can be used.

In addition, the solenoid 261 is normally turned on and can be turned off if there is a problem in the device used by the selector. In this case, of course, even if the coin put into the opening 221 is genuine, it is cancelled. In addition, while the position of the solenoid 261 is near the roller 253, the operating mechanism of the rod 265 is changed. Then, the solenoid 272 is removed and the main body frame 225, the arm 251, the metal plate 231M, and the like are removed. As a result, although not shown, the collector of the present embodiment shown in FIGS. 8 and 10 can be about half the size.

As described above, according to the present invention, the size of the entire collector can be reduced by only adding a simple configuration. That is, according to the present invention, the size of the entire collector can be reduced by employing an arc-shaped passage means. Moreover, according to this invention, the size of a sorting coin can be changed simply by replacing the roller for coin guides. Further, according to the present invention, there is an advantage that the selector can be vertically attached by employing an arc-shaped passage means and a coin guide roller. In addition, since the present invention makes the coin guide roller moveable, a great effect is obtained that the coin can be selected at an early stage.
