  The cassette body 201 is formed with a hole 205 that opens in the front side and in the up-down direction substantially at the center in the width direction, and is provided with a recess 206 that opens in the front side and is recessed in the rear direction inside the hole. Further, the upper surface plate 2011 and the lower surface plate 2012 of the cassette body 201 are formed with a recess 206 and a hole 207 communicating in the vertical direction. The concave portion 206 and the upper and lower holes 207 constitute a concave groove that is open in the front direction and the vertical direction. A pair of left and right flappers 208 and 208 are provided in the concave groove so as to be continuous in the vertical direction and disposed on opposite sides of the concave portion 206. The inner wall 209 forming the recess 206 is extended to the left and right sides at the closest position inside the front wall of the cassette body 201, and both ends thereof will be described later in cooperation with the front wall 210 or the side wall 211 of the cassette body 201. An abrasive inlet 212 and outlet 213 are formed. A pair of gears 204a and 204b that mesh with each other is provided at a position near the inlet 212 of the abrasive material accommodation space 201, and one gear 204a is urged to the other gear 204b by a pressing member 204c having elasticity. The pair of gears 204a and 204b and the pressing member 204c constitute an abrasive feed means 204.

  The flappers 208, 208 are arranged in a C shape on the extension of the ball passage forming portion 108a of the upper and lower covers 108 of the ball lifting unit 100. That is, the pair of flappers 208 and 208 is also a member that forms a spherical passage, like the upper and lower covers 108 and 112. Further, the flappers 208, 208 are U-shaped mounting plates in which upper and lower ends are fixed to the upper surface plate 2011 and the lower surface plate 2012 of the cassette body 201 by supporting shafts 208a projecting in the vertical direction at the proximal end portions on the approaching side. It is inserted into a hole (not shown) provided in 214 and supported so as to be swingable about its support shaft 208a.

  In the vicinity of the upper and lower ends of the pair of flappers 208, 208, an urging member 215 such as a leaf spring formed by bending a thin steel plate so that the planar shape is a shallow bowl shape is placed outside the side of the mounting plate 214. The free ends of the pair of flappers 208 and 208 are fixedly attached to each other, and the free ends of the pair of flappers 208 and 208 are urged toward each other. The free ends of the pair of flappers 208 and 208 exist in the vicinity of the hole 205 in the center on the front side of the cassette body 201.

An abrasive passage 216 is formed between the front wall 210 and the inner wall 209 of the cassette body 201, and is on the outer side of a straight line connecting the free ends of the flappers 208 and 208 in the abrasive passage 216, and includes an inlet 212 and an outlet. Guide rollers 217 and 218 are provided at positions close to 213.
In addition, a guide roller 219 having a diameter slightly smaller than the diameter of the game ball BC at the center on the back side of the flaps 208 and 208 in the recess 206 is rotatably supported on a shaft fixed to the upper and lower mounting plates 214. Yes.

  Then, the abrasive 203 drawn out from the outlet 213 of the cassette body 201 into the abrasive passage 216 is half-turned to the guide roller 218 on one side, and then is hung on the guide roller 219 through the free end of one flapper 208. Then, after passing through the free end of the other flapper 208 and again through the abrasive passage 216 and half-turned to the guide roller 217 on the other side, it is drawn into the inlet 212 from the abrasive passage 216. . As a result, a polishing region is formed between the facing surfaces of the pair of flappers 208 and 208 so as to face each other in a divergent shape toward the hole 205 by a part of the abrasive 203. The interval between the polishing regions changes with the opening and closing of the free ends of the flappers 208 and 208, and is set so as to be larger than the diameter of the game ball C when fully opened and smaller than the diameter of the game ball C when fully closed. Has been.

  A drive shaft (not shown) fixed to the gear 204b of the abrasive material feeding means 204 passes through a hole provided in the upper surface plate 2011 of the cassette body 201 and extends to the upper side thereof. It is fixed (see FIG. 5).

  The cassette body 201 is divided into upper and lower box bodies 201a and 201b at substantially the middle position in the height direction, and the peripheral edges of the upper and lower box bodies are abutted and joined by screws 221 as shown in FIG. Can be united. Then, the abrasive 203 can be exchanged in the two-divided state. Therefore, the abrasive can be easily replaced.

  The abrasive material cassette 200 having the shape and configuration described above has a back surface shape substantially the same as the back surface shape of the cassette body 201 of the abrasive material cassette 200 formed at an intermediate position of the unit body 101 of the ball lifting unit 100. The abrasive cassette housing space 101R can be tightly fitted and housed.

  When the abrasive cassette 200 is fitted in the abrasive cassette housing space 101R, the lifting guide 102 and the conveyor 104 of the ball lifting unit 100 enter the recess 206 of the cassette body 201 of the abrasive cassette 200, and the conveyor 104 Between the upper and lower covers 108 and 112, a portion protruding from the open surface of the lifting guide 102 enters the hole 207 in the bottom wall of the cassette body 201 of the abrasive cassette 200 and enters the hole 207. A ball communicating with upper and lower ball feeding paths p1 and p3 formed between the upper and lower covers 108 and 112 of the ball lifting unit 100 and the conveyor 104 between the conveyor 104 portion and the pair of flappers 208 and 208. A lifting path p2 is formed.

  The abrasive material cassette 200 accommodated in a predetermined position in the ball lifting unit 100 has a plurality of protrusions 222 provided on the front side of the cassette body 201 so that the front plate of the unit body 101 of the ball lifting unit 100 is It fits into a plurality of holes 117 formed at corresponding positions, and the outer peripheral surface of the cassette main body 201 of the abrasive cassette 200 is in contact with the inner peripheral surface of the accommodation space 101R of the unit main body 101 of the ball lifting unit 100. It is fixed in contact and stable.

  At that time, the transmission gear 220 of the abrasive cassette 200 is dynamically coupled with the transmission means of the cloth feed drive motor 107 of the ball lifting unit 100. The transmission means is not limited to this, but can be constituted by, for example, a bevel gear (not shown) fixed to the rotating shaft of the motor 107, and a spur gear 118 that meshes with the bevel gear and the transmission gear 220.

  Thus, when the lifting and polishing apparatus A is installed in the pachinko machine, the ball inlet 111 is provided at the end of the joining passage 12 connected to the out ball path 10 and the winning ball path 11 of the pachinko machine. 13 and the ball discharge port 114 is connected to the start end of the launch ball passage 14 connected to the ball launch position.

  Then, the effect | action by the said structure is demonstrated. When a command to supply a game ball to the firing ball passage 14 is given from a management device (not shown) to a control device (not shown) of a specific pachinko machine, the control device rotates the drive motor 105 in a predetermined direction. As a result, the conveyor 104 is rotated in a predetermined direction (counterclockwise in FIG. 12) via the gears 116 and 115, which are transmission means, so that the ball inlet 111 shown in FIG. The game ball C1 that has entered the ball introduction path 110 that is inclined downward rolls into the ball transport path p1 of the lower cover 108, and the game ball C2 that rolls into the ball transport path p1 Is conveyed by the conveyor 104. As shown in FIG. 11, the game ball C3 to be transported is continuously connected to a ball transport path p1 formed between a pair of flappers 208 and 208 existing above the lower cover 108. The ball transport path p2 is transported by the conveyor 104. As shown in FIG. 13 (a), the game ball C4 which is transported along the ball transport path p2 is supported by the flappers 208 and 208 and is urged in a direction approaching each other by the urging member 215. Polished by 203.

  In this case, as a preferred embodiment, as shown in FIG. 13 (b), the pair of flappers 208, 208 are configured so that one of a pair of flappers having the same shape with both front and back surfaces formed in a waveform having a constant period is placed above and below the other. A meandering ball feed path p2 is formed by arranging them in a symmetrical manner. Thereby, since the game ball C meanders while being transported through the ball transport path p2, the effect that the game ball C is uniformly polished by the abrasive 203 can be obtained.

  11 and 13, 208 b is a protrusion provided at the free ends of the flappers 208 and 208. If the projection 208b is not provided, the biasing force of the biasing member 215 causes the free ends of the pair of flappers 208, 208 to approach too much, narrowing the ball lifting path p2, and the game ball C to move to the ball lifting path p2. However, if this projection 208b is provided, the projection hits the edge of the hole 207 of the abrasive cassette 200 and is stopped. Therefore, narrowing of the ball transport path p2 and an excessive load on the abrasive are prevented.

  Then, the game balls polished and transported in the ball transport path p2 of the abrasive cassette 200 are further transported by the conveyor 104 along the ball transport path p3 of the upper cover 112, and the upper end portion of the ball transport path p3. Is discharged from the ball discharge port 114 through the ball outlet path 113. The number of game balls supplied from the ball discharge port 114 to the launch ball passage 14 is counted based on a detection signal supplied from the rotation detection sensor 106 to the control device. When the count value reaches a predetermined value, the control device stops the rotation of the drive motor 105.

  The number of acquisitions when the game balls that have been won win, the integration of the number of winning ball acquisitions, and the display process on the display unit 7 are performed in the same manner as in the prior art.

  In the above embodiment, the lifting guide 102, the conveyor 104, and the upper and lower covers 108, 112 constitute a lifting means for lifting the game ball introduced from the ball inlet to the ball outlet along a predetermined ball path. The drive motor 105 and the transmission gears 115 and 116 constitute a first drive means for driving the lifting means, and the abrasive material feed drive motor 107 and the transmission gear 220 constitute a second drive means for driving the abrasive material feed means. . Further, abrasives feeding means for conveying the abrasives in a predetermined direction is constituted by gears 204a, 204b sandwiching the abrasive 203 in the cassette body 201 and a transmission gear 220 fixed to the rotating shaft of the gear 204b.

  As for the abrasive transfer timing by the abrasive supply means, the frequency and degree of dirt on the game balls in the non-open pachinko machine is relatively low, so it is not necessary to frequently transfer the abrasive. Therefore, the rotational speed of the second drive means (cloth drive motor 107) may be decelerated by the speed reduction means and continuously transferred little by little, or the second drive means may be driven at regular intervals and intermittently. It may be transferred.

  For the gears 204a and 204b constituting the abrasive material feeding means of the cassette body 201, for example, an involute gear or the like in which the pitch and the groove depth are appropriately set in consideration of the strength of the waist of the abrasive material is used. By appropriately setting the elasticity of the urging member 204c, permanent deformation (tooth profile) does not occur in the abrasive bitten between the gears 204a and 204b, and a reliable feeding force is applied.

  When permanent deformation (biting mark) occurs in the abrasive 203 bited between the gears 204a and 204b, the abrasive 203 fed into the abrasive accommodating space 202 from between the gears 204a and 204b is at a short distance along the tooth profile. Since it will meander, it will be difficult to orderly accommodate in the abrasive accommodating space 202, and the serpentine abrasive will fall in the abrasive accommodating space 202, or it will be easily clogged when pulled out from the outlet 213, This is not preferable because the abrasive load is increased.

  On the other hand, when gears 204a and 204b meshing with a force that does not cause permanent deformation (tooth profile) in the abrasive material are used, the abrasive material can be reliably pulled into the abrasive material accommodation space 202 without sliding. At the same time, since the abrasive drawn from the inlet 212 moves in the direction of the outlet 213 while meandering to the left and right accurately, the abrasive is stored in an orderly manner. Accordingly, the stored abrasive is smoothly pulled out from the outlet 213. Further, the meshing of the pair of gears ensures that the abrasive is pulled into the cassette body in a tensioned state, so that the abrasive is prevented from being scraped in the polishing region.

  In the present invention, by appropriately setting the length of the abrasive material, an idle space in which the abrasive material is not packed is provided at a position near the outlet 213 of the abrasive material accommodation space 202. Therefore, the abrasive drawn from the outlet 213 can be moved to the polishing area more smoothly without being loaded at the outlet.

  Further, the game ball C is lifted upward by the lifting means, and the abrasive 203 is moved in a direction perpendicular to the lifting direction, that is, in the horizontal direction at a slow speed or intermittently, so that high polishing performance is exhibited. The Further, since the abrasive 203 has a width equal to the height of the portion excluding the range shielded by the upper and lower covers 108 and 112 of the ball lifting guide, the abrasive is used with high efficiency.

  The installation position of the lifting and polishing apparatus B with respect to the pachinko machine 1 is not limited to the back side of the pachinko machine (see FIG. 2) as in the above example, but the upper or lower part of the pachinko machine or the upper side of the pachinko machine or The lower side (see FIG. 1) is optional.

  When the lifting / polishing apparatus A is installed on the back side, upper or lower side of the pachinko machine, the abrasive cassette 200 is mounted, taken out, and the abrasive is replaced by placing the rear side of the ball lifting unit 100 on the front side of the pachinko machine (customer service). The front (customer service) door of the pachinko machine can be opened when it is attached to the side of the pachinko machine, and when the rear side of the ball lifting unit 100 is attached to the back side of the pachinko machine The entire pachinko machine can be pulled out.
