Note that the coin selector according to the present invention can be used for a coin-type game machine, a vending machine, and the like in addition to a pachislot machine.
In this specification, a coin is a general term for disk-shaped coins, medals, tokens, and the like.

As a first prior art, a so-called 3.5 inch coin selector is known.
This coin selector has a coin passage that extends vertically downward from the medal slot on the ceiling and then bends laterally to form a downward inclined passage. A small diameter medal sorting portion is provided in the middle of the slope. A passage sensor is arranged downstream of the sorting section, and the passage sensor is configured by a contact sensor (see, for example, Patent Document 1).

JP 2006-109934 A (FIGS. 7-13, pages 2-4)

In the first prior art, by detecting the output order of signals from the contact sensor, the detection signal output time, etc., it is detected that the coin is rolling normally or an improper instrument is inserted. it can.
However, since the contact sensor is configured separately from the parts that make up the coin selector, the coin resistance increases, the speed of coin selection cannot be increased, and the number of parts increases, increasing costs. There is a problem of becoming.

A first object of the present invention is to provide a coin selector that can detect a coin rolling state without increasing the coin rolling resistance.
A second object of the present invention is to provide a coin selector that can detect an illegal act on the coin selector without increasing the rolling resistance of the coin.
A third object of the present invention is to provide a coin selector that can detect a coin rolling situation and fraud without increasing the number of coin selector parts.

In order to achieve this object, the coin selector according to the present invention is configured as follows.
According to a first aspect of the present invention, there is provided a coin selector that detects passage of the coin based on a signal from a coin sensor disposed downstream of a true / false discrimination means formed along a coin path along which a coin moves. A coin detection passage (coin that the coin rolls) is provided downstream with respect to the coin passage, and the coin that rolls through the coin passage after passing the authenticity determination means is disposed offset. In order to guide to the coin detecting device, a coin moving direction changing means is provided at an upper end portion of the coin detecting passage, and the moving direction changing means is disposed on an extension of a guide rail defining a lower surface of the coin passage. Including a guide body, and the guide body is inclined downward toward the coin detection path when the coin is placed, and the coin is moved to the coin detection path. Guiding , arranging the coin sensor in the coin detection passage downstream of the moving direction changing means , and further disposing a shutter body to be displaced by the coin rolling in the coin detection passage and to prevent fraud The coin selector is provided with a first displacement sensor for detecting the displacement of the guide body and a second displacement sensor for detecting the displacement of the shutter body .
According to a first preferred embodiment of the present invention, in the coin selector according to claim 1, an illegal feature discriminating means for outputting from the displacement sensor is further provided so that when an illegal feature is discriminated, an illegal signal is output. It is characterized by that.
According to a second preferred embodiment of the present invention, in the coin selector according to the first preferred embodiment of the present invention or the first preferred embodiment of the present invention, the driven piece is disposed in a path between the authenticity determination means and the passage sensor. It is a guide body for preventing fraud arranged.
According to a third preferred embodiment of the present invention, in the coin selector according to the first preferred embodiment of the present invention or the first preferred embodiment of the present invention, the driven piece is placed in the coin path disposed downstream of the passage sensor. It is a shutter means for preventing fraud that allows passage in the rolling direction but does not allow passage in the reverse direction.
According to a fourth preferred embodiment of the present invention, in the coin selector according to the third preferred embodiment of the present invention, the shutter means is a plate-like body that can rotate around a support shaft, The coin passage is held at a shielding position, is pushed by a coin rolling on the coin passage and moved to an open position, and is held at the shielding position when pushed in the reverse direction. .

In this configuration, the coin rolls in the coin passage and reaches the authenticity determination means.
In the authenticity determination means, the false coins are excluded, and only the genuine coins roll further down the coin passage and are detected by the coin sensor and then flow out from the outlet.
The driven piece is displaced by a coin rolling in the coin passage, and this displacement is detected by a displacement sensor.
When normal, the output of signals from the coin sensor and the displacement sensor has a predetermined correlation.
However, when fraud is performed, the correlation between signals output from the coin sensor and the displacement sensor is different from that in the normal state.
As described above, when a signal correlation different from that in the normal state is detected based on the outputs from the displacement sensor and the coin sensor, an abnormal signal can be output.
Furthermore, the displacement sensor in the present invention detects the displacement of the driven piece for preventing fraud.
Therefore, in the present invention, since the dedicated contact piece is not used, the coin can be smoothly rolled without increasing the resistance against the coin rolling.

In the first preferred embodiment of the present invention, the coin selector of the present invention comprises fraudulent feature discrimination means.
As a result, the unauthorized feature determination means can determine abnormality based on the signals from the coin sensor and the displacement sensor.
Therefore, the coin selector according to the first preferred embodiment of the present invention has an advantage that an abnormal signal can be output when fraud is made.

In a third preferred embodiment of the present invention, the driven piece allows passage of the coin in the rolling direction in the coin passage disposed downstream of the coin sensor, but does not allow passage in the reverse direction. Since it is a shutter means, when the instrument is inserted from the coin exit, the shutter means is held at the shield position of the coin passage.
Therefore, there is an advantage that it is possible to prevent a fraud in which a fraudulent instrument is inserted from the coin outlet.

In a fourth preferred embodiment of the present invention, the shutter means is a plate-like body that can rotate around a support shaft, is held at the shield position of the coin passage by self-moment, and rolls the coin passage. It is pushed by the moving coin and moved to the open position, and is held at the shielding position when pushed in the reverse direction.
Then, when an instrument is inserted from the outlet for fraud, the tip of the shutter pushes the shutter means, so the tip of the shutter means is pushed to block the coin path and shields the coin path.
Therefore, there is an advantage that it is extremely difficult to perform fraud by inserting a fraudulent instrument from the outlet.

  The best mode of the present invention is a coin selector configured to detect the passage of the coin based on a signal from a coin sensor disposed downstream of a true / false determination means formed along a coin path along which the coin moves. A guide body that is displaced by a coin is provided in a coin passage downstream of the authenticity determination means and upstream of the coin sensor, and the coin rolls in the coin passage disposed downstream of the coin sensor and upstream of the outlet.

  The coin selector 100 according to the embodiment includes a main body 102, a guide rail 104, a coin passage f path 106, a diameter selection means 110 that is a true / false determination means 108 disposed in the middle of the coin path 106, a movement direction changing means 112, a movement direction. A coin detection path 114 that is a part of the coin path 106 located downstream of the changing means 112, a second main body 118 that defines the coin detection path 114, a coin sensor 116 disposed in the coin detection path 114, and a coin in the coin path 106 , The canceling means 122 for preventing the movement from the coin passage 106 to the coin detection passage 114, the shutter means 124, and the interlocking means 125 of the coin removing means 120 and the canceling means 122.

First, the main body 102 will be described with reference to FIGS. 1 to 3 and FIG.
The main body 102 is attached with components constituting the coin selector 100 and has a function of guiding one side of the coin C.
The main body 102 includes a guide wall 126 that suspends, and a left wall 127 and a right wall 130 that are bent at right angles from the left and right ends of the guide wall 126, respectively, and the suspending direction is determined by the guide wall 126, the left wall 127, and the right wall 130. A concave groove 132 extending in the direction is formed.
The width and height of the main body 102 are 3.5 inches, which is a so-called de facto standard size.
The coin selector 100 is attached to the game machine by hooking projections 134 projecting outward from the left side wall 127 and the right side wall 130 into an attachment groove (not shown) of the game machine.

Next, the guide rail 104 will be described with reference to FIGS.
The guide rail 104 has a function of guiding the coin C inserted into the insertion slot 136 in a predetermined direction while rolling.
The guide rail 104 protrudes slightly more than the thickness of the coin C from the guide surface 128 of the third main body 134, which is rotatably attached to the guide wall 126 of the main body 102, toward the guide wall 126 of the main body 102. The upper rail 104U stands up and a curved portion 104C that bends obliquely rightward in FIGS. 2 and 3 and obliquely leftward in FIG.
The guide rail 104 can be formed integrally with the third main body 134 from a material having wear resistance, but it is preferable that the guide rail 104 is formed of the metal plate guide rail 130 as in the embodiment to improve the wear resistance.

Next, the third main body 134 will be described with reference to FIGS.
The third main body 134 defines one surface of the coin passage 106, is provided with a guide rail 104, and has a function of enabling the coin C jammed in the coin passage 106 to be canceled.
The third main body 134 has a bearing 136 that protrudes in the lateral direction at the upper end of the guide wall 126, and a first shaft 138 and a second shaft 142 that protrude in parallel with the guide wall 126 from the right side wall 130. The first shaft hole 144 and the second shaft hole 146 are inserted respectively.
The first shaft 138 and the second shaft 142 are formed on the same axis L1 that inclines to the left in FIG.
Thus, as shown in FIG. 11, the third main body 134 is rotatably attached between a guide position GP parallel to the guide wall 126 and a cancel position CP in which the lower end portion is rotated from the guide wall 126 by a predetermined angle. ing.

When the third main body 134 is attached to the main body 102, the third main body 134 is held obliquely with respect to the main body 102 along the inclined edge 131 at the upper end of the left side wall 127, and the first shaft 138 is formed in the first shaft hole 144. Then, the second shaft 142 is inserted into the second shaft hole 146, shifted in the lateral direction (right direction in FIG. 8) and attached to each shaft, and then rotated toward the guide wall 126.
Thereby, the fitting part (not shown) formed in the 1st axis | shaft 138 and the shaft hole 144 fits in the 3rd main body 134, and the said fitting cannot be cancelled | released.
Further, the third main body 134 is driven by a pusher (not shown) pushed by a spring (not shown) disposed in a cylinder 148 projecting from the back surface of the guide wall 126 to the side of the second shaft hole 146. 150 receives a moment around the axis and receives a predetermined biasing force toward guide wall 126.
In other words, the third main body 134 is elastically powered so as to approach the guide wall 126.
In the center of the third main body 134, an arc-shaped drop opening 152 is formed along the coin passage 106.
The third main body 134 is provided with a driven piece 153 that extends laterally from the lower end portion on the left side wall 127 side and protrudes from the through hole 151 of the guide wall 126, and will be described later from the back side of the guide wall 126 to the guide wall 126 side. By being pushed by the exclusion means 120, the first shaft 138 and the second shaft 142 are pivoted about the fulcrum and can be moved to the cancel position CP (clockwise in FIG. 11).
As a result, the end surface of the guide rail 104 is separated from the guide wall 126 by the thickness of the coin C or more, and the guide rail 104 is inclined downward, so that the coin C that cannot roll in the coin path 106 falls from the guide rail 104. , Rejected.
The rejected coin C falls in a vertically downward direction in a reject passage 185 described later in the concave groove 132 and is rejected.

Next, the coin passage 106 will be described with reference to FIG.
The coin passage 106 has a function in which the coin C inserted into the insertion slot 136 rolls on the guide rail 104 and is guided to the moving direction changing means 112.
The coin passage 106 has a rectangular cross section defined by the guide surface 154 on the surface of the guide wall 126, the guide rail 104, the guide surface 128 of the third body 134, and the diameter selector 156, and is directed to the right in FIGS. The curved path is located in the first plane P1 (FIGS. 11 and 12).
The diameter selector 156 constitutes a so-called diameter gauge.
The guide surface 154 has a function of guiding one surface of the coin C, and is formed on the upper left side of the guide wall 126 along the guide rail 104. After slightly hanging down, the guide surface 154 curves rightward in FIG. A plurality of protrusions extending in the rolling direction are formed.
As shown in FIG. 9, the diameter selecting member 156 is fixed to the third main body 134 with a screw 165 by fitting the positioning hole 162 to the positioning pin 163 protruding from the third main body 134.
A mounting base 159 is formed so as to protrude from the upper end portion of the guide wall 126 toward the inside of the concave groove 132 relative to the third main body 134 (see FIG. 3).
The diameter selector 156 has a guide surface 160 located in the same plane as the guide surface 128 of the third main body 134 parallel to the guide wall 126, and an arcuate guide edge 164 similar to the guide rail 104. The guide rail 104 is formed at a predetermined interval.
In other words, when the genuine coin C rolls on the guide rail 104, the upper end side surface of the genuine coin C is guided to the guide surface 160 of the diameter selector 156, and the small-diameter fake coin SC is guided to the guide surface 160. Instead, it can fall from the drop opening 152 between the end of the guide surface 128 and the arcuate guide edge 164.
Therefore, the guide surface 128 and the guide surface 160 constitute a movable guide wall.

The guide surface 154 is preferably formed with a plurality of protrusions extending in the closing direction in the moving direction of the coin C to reduce the movement resistance of the coin C.
On the guide surface 128 and the guide surface 160, protrusions extending in the coin moving direction can be formed.
When coins C of different diameters are used, the distance between the arcuate guide edge 164 of the diameter selector 156 and the guide rail 104 is replaced with a different diameter selector 156.
The diameter sorter 156 is preferably made of a wear-resistant material such as a metal plate because coins rub.

Next, the diameter selecting means 110 will be described with reference to FIGS.
The diameter selecting means 110 has a function of rejecting a small-diameter fake coin SC that rolls in the coin passage 106.
The diameter selecting means 110 includes a deflecting body 172 that is a deflecting means 170 and a first biasing means 174.
The deflecting body 172 is rotatably attached to the third bearing 176L and the fourth bearing 176R provided at the upper end of the back surface of the guide wall 126 at both ends of the shaft 178 at the upper end (see FIG. 7).
The deflecting body 172 is plate-shaped and can advance and retreat into the coin passage 106 that is slightly closer to the guide rail 104 than the arc-shaped guide edge 164 of the diameter selecting body 156 through the arc-shaped opening 180 of the guide wall 126. Curved according to the curvature of the passage 106.
As shown in FIG. 2, by pushing the upper end side surface of the small-diameter false coin SC close to the diameter selecting body 156 in the horizontal direction by the deflecting body 172, the false small-diameter coin SC can be quickly removed from the coin passage 106.
Since the tip 172T (see FIG. 6) of the deflecting body 172 is inclined with respect to the coin path 106, when the deflecting body 172 is positioned in the coin path 106, the coin C inserted from the insertion port 136 is laterally moved. It is guided and receives a force pushed out from the coin passage 106.
A first weight 182 as first urging means 174 is attached to the back surface side of the guide wall 126 of the deflecting body 172, and the deflecting body 172 is clockwise with a predetermined force in FIG. Receive a moment.

As a result, the deflecting body 172 normally protrudes into the coin passage 106 with a predetermined moment.
Therefore, when the genuine coin C rolls along the guide rail 104, the upper end side surface thereof is guided by the guide surface 160 of the diameter selecting body 156 and the guide surface 128 of the third main body 134, and therefore moves in the coin path 106. .
When the small-diameter fake coin SC rolls on the guide rail 104, its upper end side surface is not guided by the guide surface 160 of the diameter selector 156, so it is brought down to the drop opening 152, dropped from the guide rail 104, and rejected. Rejected through 185.
Since the first biasing body 174 only needs to apply a biasing force to the deflecting body 172, a spring can be used instead of the weight.
However, the use of a weight is preferable because the individual variations are small and the quality is stable.

Next, the moving direction changing means 112 will be described with reference to FIG. 1, FIG. 3, and FIG.
The movement direction changing means 112 is disposed downstream of the coin passage 106 and has a function of changing the movement direction of the coin C in a different direction with respect to the coin passage 106.
In this embodiment, the coin C is guided by the moving direction changing means 112 to the coin detection path 114 that is offset with respect to the coin path 106 (see FIG. 15).
As will be described later, the coin detection passage 114 is offset behind the coin passage 106 (on the back side of the guide wall 126), and is further inclined in the second plane P2 (see FIG. 12) inclined obliquely with respect to the coin passage 106. Is located.

The moving direction changing means 112 includes a guide body 186.
As shown in FIG. 15, the guide body 186 is formed in an L-shaped cross section by a substantially horizontal elongated rectangular guide plate 186T and a substantially vertical passive piece 186P, and the guide plate 186T is inclined on the extension line of the guide rail 104. In FIG. 2, it tilts downward to the right, and one end of the front side end is rotatably attached to a support shaft 192, which is a pivot shaft, via a bearing (not shown).
The support shaft 192 is attached to a fifth bearing 194 projecting laterally from the guide wall 126 and a sixth bearing 196 projecting from the vicinity of the right side wall 130 (see FIG. 3).
As shown in FIG. 12, the support shaft 192 forms an obtuse angle with respect to the coin passage 106 in plan view.
A second weight 202, which is a second urging body 198, is fixed to a passive piece 186P that extends downward on the opposite side of the support shaft 192 of the guide body 186.
As a result, the guide body 186 receives a counterclockwise moment around the support shaft 192 in FIG. 15B, and the back surface of the passive piece 186P is prevented from rotating by the stopper 197 formed on the second body 118, whereby the guide plate 186T Is held at the standby position SP1 located on the extension of the guide rail 104.
The second urging body 198 can also be changed to other urging means such as a spring, but it is preferable to use a weight because there are few variations.
As shown in FIG. 15, the front end of the guide plate 186T is rounded downward, formed into a square sawtooth 204, and when located at the standby position SP1, it is smaller than the thickness of the genuine coin C between the guide wall 126 and the guide wall 186T. It is set to form a gap.
Therefore, when the guide plate 186t is positioned at the standby position SP1, the coin C cannot pass to the coin detection path 114.
By forming this gap, the guide body 186 is smoothly rotated.

When the coin C rolled in the coin passage 106 is placed on the guide plate 186T, the guide body 186 is rotated clockwise in FIG. 15 by the weight of the coin C and tilted downward.
When the guide body 186 is inclined downward, the distance between the front end of the guide plate 186T and the guide wall 126 can be larger than the thickness of the genuine coin C.
As a result, the coin C slides on the guide plate 186T and falls into the coin detection path 114.
Further, since the guide plate 186T forms an obtuse angle with respect to the coin passage 106, the coin C collides with the guide plate 186T at an obtuse angle.
Therefore, since the guide plate 186T is inclined downward to exhibit a toe-up inclination with respect to the coin C, the guide plate 186T is inclined not only by the weight of the coin C but also by the movement of the coin C.
As a result, the coin C can move smoothly to the coin detection path 114.
Further, the coin C is slid toward the guide wall 126 by the inclined guide plate 186T, in other words, in the lateral direction.
As a result, even if subsequent coins C are consecutive, the movement direction changing means 112 can move without jamming.

Next, the coin detection passage 114 will be described with reference to FIGS.
The coin detection passage 114 has a function of guiding the genuine coin C whose movement direction has been changed by the movement direction changing means 112 in a predetermined direction, and further, a coin sensor 116 for detecting the coin is arranged.
The coin detection passage 114 is disposed downstream of the coin passage 106 and is disposed on a substantially vertical plane different from the coin passage 106.
In other words, the coin detection passage 114 is arranged in a substantially flat second plane P2 that is offset toward the guide wall 126 with respect to the coin passage 106 (see FIG. 12).
However, the coin detection passage 114 constitutes a part of the coin passage 106.
In the present embodiment, as shown in FIG. 12, the coin detection passage 114 is arranged in a second plane P2 that is substantially vertically inclined with respect to the coin passage 106.
The moving direction changing means 112 is disposed at the upper end portion of the coin detection passage 114.
The coin detection passage 114 is defined by a detection passage guide wall 210, an arc-shaped detection portion guide rail 212 projecting laterally from the detection passage guide wall 210, and an inner surface 213 of the second main body 118, as shown in FIG. Curved downward, the downstream end is a vertically slit-shaped outlet 214 that opens substantially perpendicularly to the right side wall 130.
The detection path guide wall 210 is positioned in a second plane P2 that is inclined with respect to the coin path 106 until it passes a coin sensor 116, which will be described later, and the guide surface 154 of the coin path 106 immediately before the shutter means 124, which will be described later. It is formed so as to be located in the same plane.
Note that the coin detection passage 114 may be parallel to the coin passage 106 without being inclined.

Next, the coin sensor 116 will be described with reference to FIGS.
The coin sensor 116 has a function of detecting the genuine coin C that rolls in the coin detection path 114.
As the coin sensor 116, a transmissive photoelectric sensor, a reflective photoelectric sensor, a magnetic sensor, a contact sensor, or the like can be used, and a plurality of coin sensors are preferably arranged.
This is because by determining the output order of the detection signals, etc., it is possible to determine fraud due to insertion of a fraudulent instrument inserted from the insertion port 136 or the reject passage 185.
The coin sensor 116 is composed of a plurality of sensors of different types, that is, a transmissive photoelectric sensor 216 and a magnetic sensor 218.
In the case of using different types of sensors, in order to perform fraud, there is an advantage that fraud is made more difficult because false detection must be performed corresponding to different sensors.
In the transmissive photoelectric sensor 216 disposed on the upstream side, a light projecting unit and a light receiving unit are disposed with the coin detection passage 114 interposed therebetween.
The magnetic sensor 218 disposed adjacent to the downstream side has a coil disposed with the coin detection passage 114 interposed therebetween.
When the coin C passes through the coin detection passage 114 of the coin sensor 116, the photoelectric sensor 216 outputs the detection signal D1 for a time corresponding to the string of the coin C that blocks the transmitted light.
The magnetic sensor 218 outputs the detection signal D2 for a time corresponding to the string of the coin C that faces it.
When the guide plate 186T is pulled up by the threaded coin C, the passive piece 186P is locked by the stopper 197, and the progress is stopped at the standby position SP1 on the extension of the guide rail 104, the transmission photoelectric sensor 216 and The magnetic sensor 218 is arranged in a positional relationship for maintaining the coin C detection state.
Thereby, when the photoelectric sensor 216 and the magnetic sensor 218 simultaneously output detection signals for a predetermined time or more, it can be detected that there is an abnormality.

Next, the canceling means 122 will be described with reference to FIGS.
The cancel unit 122 has a function of guiding the genuine coin C that has passed through the authenticity determination unit 108 to advance to the cancel path 230 instead of the coin detection path 114.
The cancel passage 230 is an open passage that extends in the vertical direction on the left side of the guide body 186 in FIG.
The cancel means 122 includes a cancel piece 222 and an electromagnetic actuator 224.
The cancel piece 222 is reciprocated in a substantially horizontal plane, can be moved back and forth in the coin passage 106 above the guide body 186, and is fixed to the output shaft 228 as a vertical axis of the rotary solenoid 226 which is an electromagnetic actuator 224 that is appropriately excited. Has been.
As shown in FIG. 7, the output shaft 228 is inclined with respect to the vertical line. In the present invention, this level is a vertical range.
In this embodiment, the cancel piece 222 is formed separately into an upper cancel piece 222A and a lower cancel piece 222B, but only one of them can be used.
When the rotary solenoid 226 is demagnetized, the cancel piece 222 is rotated clockwise in FIG.
As a result, the protrusion 252 formed integrally with the cancel piece 222 abuts against the back surface of the guide wall 126 and the guide edges 254A and 254B of the cancel pieces 222A and 222B cross the coin path 106 (see FIG. 12B). Retained.
Therefore, the coin C rolling on the guide rail 104 is deflected in the lateral direction by the guide edges 254A and 254B, and dropped from the guide body 186 to the cancel path 230.
At this time, the coin C is placed on the guide body 186, but the coin C is deflected to the support shaft 192 side of the guide body 186 by the guide edge 254 before it gets on the guide body 186, so that the guide body 186 is against the moment. The guide plate 186T holds the standby position SP1.
Therefore, the coin C falls from the guide body 186 to the cancel path 230 and is cancelled.

Next, the moving direction changing portion guide 260 will be described with reference to FIGS.
The moving direction changing portion guide body 260 has a function of preventing the coin C from becoming unstable and falling to the cancel passage 230 when the coin C slides laterally on the guide plate 186T.
In this embodiment, the horizontal end portion of the inverted L-shaped member 259 is rotatably attached to the shaft 258 at the upper end of the step 257 that extends vertically upward from the middle of the cancel piece 222, and extends downward from the horizontal portion. The upright portion is a moving direction changing portion guide body 260.
The moving direction changing portion guide body 260 is disposed so as to be opposed to the most upstream portion of the cancel piece 222 on the side sandwiching the coin passage 106 with respect to the cancel piece 222 above the guide body 186.
The inverted L-shaped member 259 has a counterclockwise self-moment in FIG. 10A, and the rotation in the direction approaching the cancel piece 222 is prevented by the integral first stopper 259A contacting the surface of the step 257. Then, the second stopper 259B is held in a position parallel to the coin path 106, and the rotation in the direction away from the cancel piece 222 is prevented by the second stopper 259B coming into contact with the back surface of the step 257.
This is because the coin C can be easily dropped from the guide body 186 when the moving direction changing portion guide body 260 moves away from the cancel piece 222.
When the cancel piece 222 is positioned at the standby position SP2 that is the non-cancel position, the moving direction changing portion guide body 260 is positioned on the adjacent side of the coin path 106 and guides the coin C not to fall from the guide body 186 ( (See Figure 12 (A)).
The standby position SP2 is held when the back surface of the cancel piece 222 is locked to the interlocking means 125.
When the cancel piece 222 is located at the cancel position CP2, the moving direction changing portion guide body 260 is separated from the coin passage 106 and does not disturb the coin C falling from the guide body 186 (see FIG. 12B).

Next, the shutter means 124 will be described with reference to FIGS. 2, 3, 8, 13, and 14. FIG.
The shutter means 124 has a function of preventing insertion of a fraudulent instrument from the outlet 214 into the coin detection passage 114.
The shutter means 124 of this embodiment includes a shutter body 262.
The shutter body 262 is a plate-like plate having a crank shape in plan view (see FIG. 14), and can move forward and backward in the coin detection path 114 between the coin sensor 116 and the outlet 214.
As shown in FIG. 13, the shutter body 262 is rotatably attached to a seventh bearing 264 and an eighth bearing 266 that protrude to the front side of the second main body 118.
The seventh bearing 264 is a downward conical hole, and a conical shaft 272 formed at the upper end of the end of the shutter body 262 is rotatably inserted.
The eighth bearing 266 is a conical hole, and a conical shaft formed at the lower end of the end of the shutter body 262 is rotatably fitted.
The conical angle of the conical hole of the eighth bearing 268 is formed to be larger than the conical angle of the conical shaft, and the rotational resistance of the shutter body 262 is formed to be smaller.
The axes of the seventh bearing 264 and the eighth bearing 286 are arranged on the same axis as shown in FIG. 2 and are perpendicular to the extending direction of the coin detection passage 114 in front view, in other words, the rolling direction of the coin C. It is arranged to make.

Therefore, the shutter body 262 is attached obliquely to the main body 102 as shown in FIG. 2, and receives a moment around the axis line by the position of its center of gravity.
The shutter body 262 is set to rotate counterclockwise in FIG. 14 by the self-moment.
In other words, the front end 262T of the shutter body 262 normally rotates toward the coin detection passage wall 210 and is in contact with the bottom of the receiving groove 268 formed in the coin detection passage wall 210 with a predetermined force.
At this time, the tip 262T is inclined toward the downstream side in the coin movement direction in the coin detection passage 114.
Thereby, when the coin C rolls in the coin detection passage 114, the tip 262T of the shutter body 262 is pushed by the rolling coin C and rotated clockwise in FIG. 14, and the coin C moves to the exit 214. be able to.
At this time, since the shutter body 262 receives the rotational force from the direction orthogonal to the rotation axis by the coin C, it can rotate smoothly.
Therefore, the coin C passes through the shutter body 262 without jamming in the coin detection path 114.
When a fraudulent instrument is inserted from the outlet 214, the shutter body 262 is pushed on the inclined surface and is pushed counterclockwise in FIG. 14, so that the tip 262T of the shutter body 262 is pressed against the receiving groove 268 with a greater force, The above progress is prevented.
In other words, the shutter body 262 continues the shielding position of the coin detection path 114.
Therefore, the coin sensor 116 is not cheated by the instrument inserted from the outlet 214.

Next, the coin exclusion means 120 will be described with reference to FIGS.
The coin removing means 120 has a function of removing coins jammed in the coin passage 106 from the coin passage 106, extends adjacent to the guide wall 126, and has bearings 272A and 272B on the lower surface on a shaft 178 which is a pivot shaft. It comprises a plate-like driven lever 274 that is rotatably attached, a pushing lever 276 that extends downward from the driven lever 274, and a diameter selector 156, and has a function of moving the third main body 134 to the cancel position CP.
In order to more reliably remove the coin C from the coin passage 106, it is preferable to include a moving hook 278 which is a coin locking body formed integrally with the diameter selecting body 156.
The lower end of the driven lever 274 is opposed to the tip of the driven piece 153, and in a standby state, the driven lever 274 is rotated counterclockwise in the vertical direction in FIG. It is held at the standby position SP3 in the horizontal state.
When a cancel lever (not shown) of the game machine is canceled, the end of the driven lever 274 is pushed down, rotated counterclockwise in FIG. 5, and rotated to the state of FIG. 17 (B). .
As a result, the pushing lever 276 pushes the driven piece 153, so that the third main body 134 is rotated as shown in FIGS. 17B and 17C to the cancel position CP.

The moving hook 278 has an inverted channel shape and has a coin passage groove 282, and is positioned so as to surround the upper end portion of the coin passage 106 when the third main body 134 is located at the standby position SP3.
The upper end portion of the genuine coin C rolling on the coin passage 106 reaches the guide plate 186 through the coin passage groove 282.
When the coin C jams in the coin passage 106 and stops rolling, the third main body 134 is rotated as shown in FIGS. 17B and 17C, and when the coin C is positioned at the cancel position CP, the upper end of the coin C is The moving hook 278 is forcibly separated from the guide surface 154 and, as a result, is dropped from the guide rail 104.

Next, the interlocking means 125 will be described.
When the coin removing means 120 is operated to remove a coin, the interlocking means 125 is linked to the canceling operation 122, and therefore, even if the cancel piece 222 is located at the standby position SP2, the cancel position CP2 It has a function to move to.
The interlocking means 125 is an interlocking lever 284 that extends downward from the driven lever 274 and has a lower end located on the side of the driven protrusion 282 on the back surface of the cancel piece 222.
The interlocking lever 284 is formed of resin integrally with the driven lever 274 and is configured to be elastically deformable.
This is to avoid breakage or the like due to elastic deformation even if an excessive force is applied.
When the driven lever 274 is positioned at the standby position SP3, the lower end portion of the interlocking lever 284 is opposed to the driven protrusion 282.
When the rotary solenoid 226 is excited, the cancel piece 222 is rotated counterclockwise in FIG. 12, and the protrusion 252 is blocked by the back surface of the guide wall 126 at the position where the guide edges 254A and 254B are retracted from the coin path 106. The rotation is stopped.
In the case where the cancel piece 222 is located at this retracted position, if the coin removing means 120 is operated for exclusion, in other words, the driven lever 274 is rotated counterclockwise in FIG. 5, and the position shown in FIG. , The lower end of the interlocking lever 274 pushes the driven projection 282, so that the cancel piece 222 is rotated toward the guide wall 126 against the rotational power of the rotary solenoid 226 and moved to the cancel position CP2.
After the protrusion 252 is prevented from moving to the back surface of the guide wall 126, the interlocking lever 274 is elastically deformed, and the cancel piece 222 is not overloaded.

Next, a displacement sensor 300 according to the present invention will be described with reference to FIG.
The displacement sensor 300 in this embodiment uses a guide body 186 and a shutter body 262 as a driven piece 302 that is displaced by a coin C rolling in the coin path 106 and prevents fraud.
In this embodiment, a first displacement sensor 304 and a second displacement sensor 306 are used.
However, the displacement sensor 300 may be either one, but can be further increased.
First, the first displacement sensor 304 will be described.

The first displacement sensor 304 detects the displacement of the guide body 186 of the moving direction changing unit 112.
In this embodiment, the displacement of the guide body 186 indirectly detects the position of the second weight 202 fixed integrally with the guide body 186 by the second photoelectric sensor 308.
However, the position of the guide body 186 can be directly detected.
The guide body 186 has a function that makes it difficult to insert the instrument into the coin detection passage 114 as described above.
The second photoelectric sensor 308 is a transmissive photoelectric sensor including a projector 310 and a light receiver 312.
When the guide body 186 is positioned at the standby position SP1, the second weight 202 is disposed in a positional relationship where the projection light from the projector 310 is blocked.
Therefore, when the guide body 186 is rotated by the coin C, the light receiver 312 receives the light from the projector 310 by the movement of the second weight 202 interlocked therewith.
When the light receiver 312 receives light, the first displacement sensor 304 outputs a detection signal D3.
Note that the second weight 202 may block the projection light from the projector 310 by the movement of the second weight 202.

Next, the second displacement sensor 306 will be described.
Similar to the first sensor 304, the second displacement sensor 306 is a transmissive photoelectric sensor including a projector 314 and a light receiver 316.
The projection light from the projector 314 is blocked by the movement of the shutter body 262 constituting the shutter unit 124.
When the light receiver 316 does not receive the projection light, the second displacement sensor 306 outputs a detection signal D4.
Note that the blocking of the projection light may be released by the movement of the shutter body 262, and the light receiver 316 may receive the light.
Output signals of the photoelectric sensor 216 and the magnetic sensor 218 constituting the first displacement sensor 304, the second displacement sensor 306, and the coin sensor 116 are supplied to a microcomputer 320 serving as an illegal feature discrimination means 318.
The microcomputer 320 performs predetermined processing based on a program stored in the ROM, determines whether the coin selector 100 is abnormal, and outputs an abnormality signal ES when there is an abnormality.

Next, the operation of this embodiment will be described.
When the game machine or the like equipped with the coin selector 100 is not in a state of accepting the coin C, the rotary solenoid 226 is demagnetized, so that the cancel piece 222 is rotated by the spring 229, as shown in FIG. The cancel position CP2 advanced into the coin passage 106 is held.

When the genuine coin C is inserted into the insertion slot 136, the coin C rolls on the guide rail 104 while being guided on both sides by the guide surface 154, the guide surface 128 of the third main body 134, and the guide surface 160 of the diameter selector 156. To reach the cancellation piece 222.
The coin C is guided by the guide edges 254A and 254B of the cancel pieces 222A and 222B crossing the coin passage 106 before getting on the guide plate 186T, is deflected to the support shaft 192 side of the guide plate 186T, and is dropped to the cancel passage 230. It is done.

Next, a case where the coin selector 100 is in the coin C acceptance state will be described.
In other words, as shown in FIG. 12A, the rotary solenoid 226 is excited and the cancel piece 222 is retracted from the coin path 106.
First, a case where a genuine coin C is inserted will be described.
The genuine coin C rolls on the guide rail 104 and reaches the authenticity determination unit 110.
In the diameter selecting means 110 that is the authenticity determination unit 108, the genuine coin C is deflected in the lateral direction by the tip 172T of the deflecting body 172 that crosses the coin passage 106.
However, since the upper end side surface of the genuine coin C is guided by the guide surface 160 of the diameter selector 156 and the lower end side surface is guided by the guide surface 128 of the third main body 134, the coin C falls down the authenticity determination unit 110. Pass through without reaching the guide 186.
The guide body 186 receives a moment in the clockwise direction of the support shaft 192 in FIG. 15 by the genuine coin C riding on the guide plate 186T, and rotates.
Accordingly, the guide plate 186T is rotated clockwise in FIG. 15 by the weight of the genuine coin C and the moment generated by the collision of the coin C.
Therefore, the genuine coin C slides on the guide body 186 and moves to the coin detection passage 114 offset in the lateral direction with respect to the coin passage 106, and rolls on the detection unit guide rail 212.
The projection light from the projector 310 is received by the light receiver 312 by the rotation of the guide plate 186T. Therefore, the first displacement sensor 304 outputs the detection signal D3 while receiving light.
Since the coin C rolling on the detection unit guide rail 212 blocks the light transmitted through the photoelectric sensor 216, the photoelectric sensor 216 outputs the detection signal D1, and immediately after that, the magnetic sensor 218 also detects the metal coin and detects the detection signal. D2 is output.
These detection signals D1 and D2 are also used for counting genuine coins C and the like.
Further, the genuine coin C pushes the shutter body 262, rotates it clockwise in FIG. 14, passes through the shutter means 124, and is taken into the game machine from the outlet 214.
Since the projection light from the projector 314 is blocked by the shutter body 262 by the rotation of the shutter body 262, the second displacement sensor 306 outputs the detection signal D4.

Next, a case where a small-diameter fake coin SC is inserted will be described.
In the authenticity determination unit 110, the upper end side surface of the small-diameter fake coin SC is not guided by the diameter selector 156.
Therefore, since the upper end portion of the small-diameter false coin C is pushed out to the drop opening 152 by the pushing force from the lateral direction of the deflecting body 172, the coin C turns over and falls from the guide rail 104 to the reject passage 185, and is rejected. Is done.

Next, a case where a large-diameter fake coin is inserted will be described.
The large-diameter fake coin is sandwiched between the peripheral edge of the mounting base 159 and the guide rail 104 and cannot roll on the coin path 106.
In this case, the exclusion means 120 is excluded.
That is, the driven lever 274 is rotated clockwise in FIG. 15 by the operation of the cancel lever of the game machine, and is rotated to the position of FIG.
As a result, the lower end of the pushing lever 276 pushes the driven piece 153 and turns the third main body 134 about the axis L1 to turn to the cancel position CP (see FIGS. 11 and 16 (B and C)).
As a result, an interval equal to or greater than the thickness of the coin C is formed between the end surface of the guide rail 104 of the third main body 134 and the guide surface 154, and the upper surface of the guide rail 104 is inclined downward. Since 278 separates the upper part of the coin C from the guide surface 154, the coin C that has become unable to move falls from the guide rail 104 to the reject passage 185 and is rejected.
At this time, even if the rotary solenoid 226 is continuously excited, the interlocking lever 284 pushes the driven projection 282 by the rotation of the driven lever, and the cancel piece 222 is forcibly moved to the cancel position CP2.
As a result, the coin C that has reached the guide body 186 is pushed from the guide body 186 by the cancel piece 222 and dropped into the cancel path 230.
Therefore, when the exclusion means 120 is operated, the coin C does not move to the coin detection path 114.

Next, a case where an illegal instrument is inserted into the insertion port 136 will be described.
Even when the fraudulent instrument is inserted along the coin path 106, it is necessary to advance to the coin detection path 114 located on a different plane P2 that is offset from the coin path 106.
However, in order to advance the fraudulent instrument in a narrow range to the offset coin detection path 114, the fraudulent instrument must have great flexibility, and it is extremely difficult. You cannot proceed to
Even if the fraudulent instrument is inserted into the coin detection passage 114, the guide body 186 is displaced for a longer time than the passage of the coin C. Therefore, the first displacement sensor 304 continuously detects the detection signal D3 over a predetermined time. Output.
When the detection signal D3 continues for a predetermined time or more, it can be determined that some abnormality has occurred, and the abnormality signal ES can be output.
Therefore, the coin sensor 116 cannot be cheated by the cheating tool inserted from the insertion port 136.
Further, even if the coin C is tied to the genuine coin C and the coin sensor 116 is turned ON / OFF, when the coin C is pulled up, the coin C is locked to the guide body 186, and the guide body 186 is rotated counterclockwise in FIG. Turn to.
As a result, the guide body 186 can rotate to the standby position SP1 on the extension of the guide rail 104.
Therefore, since the coin C is continuously detected for a predetermined time or more by the photoelectric sensor 216 and the magnetic sensor 218 as described above, the hanging of the coin C can be detected and an alarm can be issued. I can not.

Next, a case where a fraudulent instrument is inserted into the outlet 214 will be described.
When a fraudulent instrument is inserted into the outlet 214, the tip 262T of the shutter body 262 is moved counterclockwise in FIG. 14 by the instrument, so that the tip is pressed against the bottom of the receiving groove 268 and the coin detection passage 114 is shielded. Will continue.
Therefore, the fraudulent instrument inserted into the outlet 214 cannot be used to cheat the coin sensor 116.

Next, abnormality determination based on signals from the first displacement sensor 304, the second displacement sensor 306, and the coin sensor 116 will be described with reference to FIG.
First, a normal case will be described.
The guide body 186, and hence the second weight 202 is rotated clockwise in FIG. 15B until the coin C rests on the guide body 186 and passes by the side of the guide body 186, so that the projection from the projector 310 is performed. The light is received by the light receiver 312 without being blocked by the second weight 202.
Thereby, the first displacement sensor 304 outputs a detection signal D3 having a time length T1 substantially corresponding to the diameter of the coin C when the guide body 186 is rotated by the coin C.

Next, the coin C rolling on the coin detection path 114 passes through the coin sensor 116.
Thus, after a time T2 from the start of output of the detection signal D3, the photoelectric sensor 216 outputs a detection signal D1 of a time length T3 corresponding to the chord length of the coin C, and after a time T4 from the start of output of the detection signal D3, the magnetic The sensor 218 outputs a detection signal D2 having a time length T5 corresponding to the string length of the coin C.
Further, the coin C rolls by rotating the shutter plate 262.

The second displacement sensor 306 outputs the detection signal D4 for a time T7 corresponding to the diameter of the coin C in which the shutter plate 262 is rotated by the coin C after a time T6 from the output start of the detection signal D1.
As a result, by detecting that the detection signals D3, D1, D2, and D4 are output in this order by the information processing in the microcomputer 318 and that they are output with a predetermined time difference, it is possible to pass normal coins. It can be determined.
When the output order of the detection signals D1 to D4 and their temporal correlation do not have a predetermined relationship, it can be determined that there is an abnormality.
For example, when only the detection signal D1 is output and the detection signals D3, D2, and D4 are not output, it can be determined that the fraud is caused by infrared rays.

In addition, if the detection signal D3 is continuously output over the T1 time and the detection signals D1, D2, and D4 are output at regular timing, fraud is performed by the instrument inserted in the detection passage 114. Can be determined.
Furthermore, when the detection signal T1 of the first displacement sensor 304 is output for a predetermined time T8 or more, an abnormality in the first shaft 194 and the second shaft 196 of the guide body 186 can be estimated.
Similarly, when the detection signal D4 is output beyond the predetermined time T9, it can be estimated that the bearings 272 and 272 are abnormal.
Therefore, in these cases, the unauthorized feature determination means 318 outputs a bearing abnormality signal ES.

Furthermore, when the signal D4 is continuously output, it can be estimated that an unauthorized device has been inserted from the outlet 214, and thus the determination means 316 outputs an abnormal signal ES.
In the present invention, since the abnormal signal ES can be output using the guide body 186 and the shutter plate 262 for preventing fraud, no new contact piece with the coin is provided.
Therefore, since the thing which becomes rolling resistance of the coin C does not increase, it has an advantage which does not increase coin jam.
