JP-A-9-293155 (FIGS. 1 to 5, paragraphs 0004 to 0020) Patent No. 370967 (FIGS. 1 to 5, paragraphs 0004 to 0026) JP-A-5-45104 (FIGS. 1 to 3, paragraphs 0006 to 0035) JP 2007-178235 (FIGS. 1 to 6, paragraphs 0006 to 0020)

In the first related art, the diameter of a disc is measured based on the number of pulses from when a pulse signal is output from a movement detecting unit to when the rotating body rotates to a predetermined angular position in the normal rotation. In this kind of diameter measuring apparatus for a disk, when the disk is clogged, the rotating body is reversed and an automatic solution is attempted. In the first prior art, when the rotating body is reversed just after the disk body has moved the movement detecting means, in other words, in order to send out the disk body in a state where the disk body has not been released yet. When the rotating body is reversed, the disc body is returned but a pulse for diameter determination is output and counting continues, or a pulse signal is output because the movement is in the opposite direction. Not done. Thereafter, the rotating body is rotated forward again, a pulse is output, and the disc body is determined. This situation will be described with reference to FIG. In the description of the related art, it is assumed that the encoder of the rotating body does not output a pulse signal when the rotating body rotates in the reverse direction. When the pulse signal is output from the movement detecting means, the signal processing means counts a high-frequency pulse signal accompanying the rotation of the rotating body from the encoder (displayed in a stepwise manner). After the rotation of the rotating body is stopped on this way, if the rotation is reversed, the pulse signal is not output during the reverse rotation, so the count value does not change. The diameter of the disc body is measured based on the count value E of the pulse signal at the time when the predetermined angular position signal is output from the rotating body. However, if the measurement is performed normally without the reversal, the pulse signal (shown by a dashed line in the figure) output during the time when the reversal is reached is also counted. N becomes larger than the count value at the time of reverse rotation. In other words, when the rotating body is reversed, there is a problem that the disc body is determined to have a smaller diameter than the actual one. When a pulse signal is output even when the rotating body rotates in the reverse direction, the count value becomes larger than in the normal case, so that there is a problem that the disc body is determined to be larger in diameter than the actual one.
According to a second related art, in a disk-body discharging device that discharges disk bodies one by one by rotating means, movement of a moving portion moved by the disk body as a means for detecting the diameter of the discharged disk body. The amount is detected by each of the first and second encoders, the number of rising edges of the pulse signal emitted from the first encoder is counted, and the counting at the conversion point of the phase of the pulse signal output from the first and second encoders is performed. It is configured to determine the diameter of the disc body based on the edge count value obtained.
In the second conventional technique, when the rotating means is reversed just after the disc body has moved the moving part, in other words, in a state where the disc body has not yet been released, the first and second encoders have not yet released the disc body. Since a conversion point of the phase of the output pulse signal occurs, the diameter of the disc is determined based on the count value of the number of edges of the pulse at the time when the conversion point occurs. In this case, since the disc is in the process of being dispensed, the count value is smaller than the actual diameter, so that the abnormal disc is treated as being dispensed, that is, despite being normal, There is a problem that is determined to be abnormal.
In the third conventional technique, a peripheral surface of a coin is pressed against a reference side surface by a measuring piece, the rotation of the measuring piece is enlarged by a gear and converted into resistance by a potentiometer, and a change pattern of the resistance is defined as a reference pattern. Since the diameter of the coin is determined by comparison, when the coin returns in the middle as described above, the difference in the resistance pattern is different from that in the normal case. There are problems that arise.
A fourth prior art is an optical rotary encoder including a rotating rim having a light projecting portion and a light blocking portion, and a pair of a light emitting element and a light receiving element arranged with the rim interposed therebetween. Since a pulse signal having a phase difference can be output by using the light emitting element and the light receiving element, it is conceivable to change the encoder in the first or second conventional technique to a rotary encoder in the fourth conventional technique. However, even in this case, in the first prior art, since the diameter of the disc body is determined based on the count value of the pulse output at the time of reverse rotation, it is practically the same as in the first prior art. There is a problem that the diameter is determined to be larger than that. In the second prior art, since the diameter of the disc is determined based on the count value at the conversion point in the rotation direction of the rim, there is a problem similar to the second prior art.

In consideration of durability, a metal flat plate made of stainless steel or the like is formed in a size that can be closely fitted into the rotating body hole 124. Further, a roughly rectangular advance / retreat hole 148 through which a later-described regulating plate 118 can advance / retreat is formed.

Next, the regulating plate hole 126 will be described.

When the slide plate 144 is formed and assembled, the hole is formed so as to be substantially entirely surrounded.

Next, the locking portion 128 will be described.
The locking portion 128 has a function of detachably attaching a base portion of a disk storage container 114 described later to the substrate 112, and has a locking hole 140 formed in the disk storage container 114 and a protrusion formed on the substrate 112. The disk holding container 114 is removably attached to the substrate 112 in cooperation with the locking portion 128.

Next, the curved portion rotary disc hole 134A will be described.
The curved portion rotating disk hole 134A has a function of rotatably mounting a curved portion rotating disk 132F, which will be described later. In this embodiment, a predetermined portion formed near the disc opening 142 of the rotating body hole 124 is provided. It is formed by a ring-shaped hole having a diameter.

Next, the disk holding container 114 will be described mainly with reference to FIG.
The disc holding container 114 has a function of holding the discs 102 in a bulk state, and in the present embodiment, is a vertical cylindrical body, and the upper end portion 114U is a roughly rectangular shape in plan view, The lower end portion 114B extends substantially in the shape of a cylinder on the extension of the rotary body hole 124, and is detachably attached to the substrate 112 as described above.

Next, the rotating body 116 will be described mainly with reference to FIG.
The rotating body 116 has a function of separating the disc bodies 102 held in a bulk state in the disc holding container 114 one by one and pushing the disc bodies 102 in a radial direction of the rotating body 116 at the disc body opening 142. In the embodiment, the speed reducer 154 is constituted by a circular plate having a predetermined thickness, and is arranged at the bottom of the disc body storage container 114 in parallel with the substrate 112 and by an electric motor 152 disposed on the back side of the substrate 112. At a predetermined speed. In addition, the rotating body 116 penetrates the rotating body 116 from the upper side to the lower side at an interval of 120 degrees on the same radius around the rotation axis, and the rotating body 116 Also, a through hole 146 having a slightly larger diameter is formed. Specifically, three through holes 146 are formed. With this configuration, when the rotating body 116 is rotated at a predetermined speed in the counterclockwise direction indicated by the arrow in FIG. 3A, the retained disc 102 is stirred by the rotation of the rotating body 116. While being changed to various postures, it falls into the through hole 146, and the front surface or the back surface comes into surface contact with the substrate 112. Therefore, between the substrate 112 and the lower surface of the rotating body 116, a moving passage 150 (FIG. 6) of the ring-shaped disk body 102 whose outer periphery is surrounded by the circular wall 138 is formed. On the back surface of the rotating body 116, a pushing portion 156, a pushing portion 158 at the time of reverse rotation, a ridge 162, and a pressing slope 164 at the time of reverse rotation are formed corresponding to each through hole 146. Therefore, the pushing portion 156, the pushing portion 158 at the time of reverse rotation, the ridge 162, and the pressing slope 164 at the time of reverse rotation move in the moving passage 150. In the present embodiment, the outer peripheral edge of the rotating body 116 is formed in a narrow ring-shaped portion 166 whose upper edge is slightly raised to a position in contact with the through hole 146. The narrow ring-shaped portion 166 is inserted into a circular hole of the lower end portion 114B of the disk holding container 114, and is arranged in a concave portion (not shown) in which the diameter of the circular hole is enlarged, so that the inner wall of the circular hole is formed. Since the disc 102 is located so as to be hidden, the disc 102 is prevented from being bitten between the rotating body 116 and the disc holding container 114. Further, a shaft hole 168 into which an output shaft (not shown) of the speed reducer 154 is fitted is formed in a central portion, and a driving portion 171 is formed around the shaft hole 168. In the present embodiment, a driving cam 172 is formed. Have been.

Next, the pushing portion 156 will be described. In the present embodiment, three pushing portions 156 are formed, but since the configurations are all the same, the same reference numerals are given and only one portion is described as a representative.
The pushing portion 156 has a function of pushing the disc body 102 in contact with the substrate 112 and sliding on the substrate 112 (sliding plate 144). It is formed to extend in the radial direction of the rotating body 116 approximately, and includes a pushing portion 176 and a pushing portion 178.

Next, the pushing portion 176 will be described.
The pushing portion 176 has a function of pushing the disc 102 in a region where the disc 102 is guided by the circular wall 138 and causing the disc 102 to be rotated by the rotating body 116. This is a portion formed in an inward arc shape protruding downward by a predetermined width along the periphery of the through hole 146 located at the rear side in the rotation direction when the 116 rotates forward. Therefore, at the time of operation, a small gap is formed between the pushing portion lower surface 182 and the circular bottom surface 136 such that they do not rub against each other, and the disc 102 can move in the radial direction of the rotating body 116. A gap is formed between the outer peripheral edge lower surface 184 and the disk 102 having the maximum thickness. Inward means toward the through hole 146. Therefore, the pushing portion 176 forms an elongated continuous surface having a predetermined width. As described above, the pushing portion 176 has an uninterrupted narrow surface shape, so that there is an advantage that the pushing can smoothly be performed when pushing the disc 102. Further, by making the pushing portion 176 in an inwardly arcuate shape, even when the pushing portion 176 pushes the largest-diameter disc body 102L or the smallest-diameter disc body 102S, the disc body 102 has a circular wall. 138, the first contact point P1 of the disc 102 and the pushing portion 176 is located outside the center CC of the disc 102, and the center of the rotating body 116 is moved from the first contact point P1. Side force acts to generate a component force in the direction of canceling the centrifugal force acting on the disc 102, so that the pressure contact force on the inner surface of the disc holding container 114 is reduced, and the durability of the apparatus is improved. This has the effect of preventing damage to the disk 102.

Next, the pushing section 178 will be described.
When the disc 102 pushed by the pushing portion 176 is located in the disc opening 142 and guided by the regulating plate 118 in the radial direction of the rotating body 116, the pushing portion 178 pushes the disc 102. Has a function of pushing the peripheral surface of the rotary member 116 toward the curved portion rotating plate 132C. It is configured. That is, the pushing portion 178 has an arcuate shape connected to the pushing portion 176, and faces the outer peripheral edge lower surface 184 and faces outward at an angle of about 10 degrees with respect to a straight line L1 passing through the center of the rotating body 116. Is formed.

Next, the boundary portion 180 will be described.
The boundary part 180 is a part formed at the boundary between the pushing part 176 and the pushing part 178, and the second contact point P2 between the straight line L1 and the pushing part 156 is formed The pushing portion 176 and the pushing portion 178 are formed by smooth curved surfaces. The first contact point P1 is located closer to the rotation axis RS of the rotating body 116 than the second contact point P2. Therefore, the boundary between the pushing portion 176 of the inward arc portion and the pushing portion 178 of the outward portion becomes the boundary portion 180. However, since the pushing portion 176 and the pushing portion 178 are connected by a smooth curve, the boundary portion 180 actually has a planar shape having a predetermined width.

Next, the driving unit 171 will be described with reference to FIG.
The drive unit 171 has a function of causing the regulating plate 118 to move in and out of the movement passage 150 at a predetermined timing, specifically, a function of moving the regulating plate 118 so as not to interfere with the pushing portion 156 formed on the back surface of the rotating body 116. In this embodiment, the driving cam 172 is provided.

Next, the drive cam 172 will be described.
The driving cam 172 has a function of cooperating with the regulating plate 118 and causing the regulating plate 118 to protrude and retract in the moving passage 150 at a predetermined timing. In the present embodiment, the driving cam 172 is arranged at three locations corresponding to the through holes 146. Are the same in configuration, and only one will be described as a representative. The drive cam 172 is formed in an arc-shaped groove 170 having a predetermined radius around the rotation axis RS of the rotator 116, formed at one end of the arc-shaped groove 170, and configured to rotate the rotator 116 forward (disc 102 A downward slope 172D which becomes a downhill at the time of pressing by the pushing part 176), an uphill slope 172U formed at the other end, and a downhill slope 172D formed between the downhill slope 172D and the uphill slope 172U. Is connected to the deepest part of the ascending slope 172U at the same depth. In other words, the drive cam 172 is formed in a groove shape whose cross section in the circumferential direction is inclined.

Next, the regulating plate 118 will be described mainly with reference to FIG.
The regulating plate 118 has a function of guiding the disc 102 pushed by the pushing portion 176 and the pushing portion 178 in the radial direction of the rotating body 116 by the rotation of the rotating body 116, and in this embodiment, The regulating body 186 is formed in the regulating plate hole 126. The restricting body 186 is formed in an inverted L-shape as shown in FIGS. 5 and 6, and extends from the main body 188 to the rotation center side of the rotating body 116. And the driven part 192 which is provided.
One end 188E of the main body 188 is provided with a support portion 194 formed in a frog crotch shape, the other end 188O is provided with a regulating plate 118, and the intermediate portion 188M is provided with a guide portion 196.

Next, the support portion 194 will be described.
The support portion 194 has a function of receiving the force acting on the regulating plate 118 and holding the body portion 188 so that the posture can be changed within a predetermined range. In this embodiment, the support portion 194 is fixed to the sliding plate 144 in an inverted state. The self-aligning bearing 198 is fitted in the frog crotch.

Next, the guide section 196 will be described.
The guide portion 196 has a function of regulating the movement of the regulation plate 118 within a predetermined range. In this embodiment, the guide portion 196 is fixed downward to the elongated hole 202 formed in the intermediate portion 188M and the sliding plate 144, The distal end is constituted by a fixing pin 203 inserted into the elongated hole 202. With this configuration, the restricting body 186 can move three-dimensionally with respect to the sliding plate 144 within a range in which the movement of the support portion 194 is not restricted by the fixing pin 203.

  The regulating plate 118 has a function of preventing the disk body 102 pushed by the pushing portion 176 from rotating together and guiding the disc body 102 in the radial direction of the rotating body 116. In the present embodiment, the regulating body 186 is formed. The other end portion 188O of the main body portion 188 is formed so as to project upward at right angles to the main body portion 188. In this embodiment, the restricting plate 118 is divided into an inner restricting plate 118I and an outer restricting plate 118O close to the rotation center of the rotating body 116 by a receiving groove 206 formed in the middle to receive an outer ridge 162O described later. . An end surface of the restriction plate 118 on the side opposite to the support portion 194 is a restriction surface 208. Therefore, the regulating surface 208 is also divided into an inner regulating surface 208I and an outer regulating surface 208O. The restricting body 186 can protrude and retract above the sliding plate 144 through an advance / retreat hole 148 formed in the sliding plate 144. Usually, the lower surface of the main body 188 of the restricting body 186 and the bottom surface of the restricting plate hole 126 The spring 214 as the urging portion 204 disposed between the two protrudes above the sliding plate 144 and is urged to be located at the regulation position CP (FIG. 8) located in the moving passage 150. When the restricting body 186 protrudes above the sliding plate 144, the upper end protrudes into the moving passage 150, and thus the moving surface of the pressing part 176, but the driven cam 212 causes the pressing part 176 to move to the restricting body 186. In accordance with the movement so as not to collide, the slide plate 144 is moved to a retreat position PP (FIG. 6B) that has withdrawn from the surface of the slide plate 144. As shown in FIG. 8, when the sliding plate 144 is located below the through hole 146, the total length thereof, that is, the total length of the inner regulating plate 118I, the receiving groove 206 and the outer regulating plate 118O is smaller than the diameter of the through hole 146. Are also formed slightly shorter. The term “slightly shorter” is used as a guide when it is 70% or more of the diameter of the through hole 146. In the case where the length of the regulating surface 208 is short, for example, in the case of 10 yen, 50 yen, 100 yen and 500 yen coins in Japanese yen, when sending out the 50 yen coin which is the disc 102 having the minimum diameter, This is because a 50-yen coin may not be guided smoothly and may not be smoothly sent out.

Next, the regulating surface 208 will be described.
The regulating surface 208 has a function of guiding the disk body 102 in the radial direction of the rotating body 116. In this embodiment, in order to prevent wear due to sliding with the disk body 102, the restriction surface 208 is made of metal, or , And the resin is covered with a metal plate.

  In this embodiment, a reverse rotation driven portion 210 is further formed on the regulating plate 118. The reverse rotation driven portion 210 is retracted from the movement path of the pushing portion 156 when the rotating body 116 rotates in the reverse direction, and thus has a function of being pushed down by the reverse rotation pressing slope 164 of the rotating body 116. The regulating plate 118 is formed on the opposite side of the regulating surface 208 from the regulating surface 208, and is formed on a slope that rises forward toward the regulating surface 208 and has a planar shape. Specifically, a driven portion 210I at the time of inner reverse rotation is formed relative to the inner regulating surface 208I, and a driven portion 210O at the time of outer reverse rotation is formed relative to the outer regulating surface 208O. Further, when the driven portion 210 at the time of reverse rotation in the present embodiment is a climbing slope, it is also the climbing slope 220 of the disc 102. When the rotating body 116 is reversed, the disc body 102 pushed by the pushing unit 158 at the time of reverse rotation can be passed over the climbing slope 220 by being guided by the climbing slope 220. However, the inner reverse rotation driven portion 210I and the outer reverse rotation driven portion 210O only need to be able to exhibit their functions, and therefore may have a shape other than a slope.

Next, the driven cam 212 will be described.
The driven cam 212 cooperates with the drive cam 172 to prevent the restricting body 186 from interfering with the rotating body 116. In other words, during the process in which the pushing portion 156 moves through the moving passage 150, the restricting body 186 In the present embodiment, the driven cam 212 is pushed by the driving cam 172 to move the regulating body 186 below the sliding plate 144, and has a function of preventing the collision with the pushing portion 156. The body 186 is configured to move up and down with respect to the slide plate 144. Specifically, the driven cam 212 has an ascending portion 212U, a retreat continuation portion 212H, and a descending portion 212D, and is fitted into the arc-shaped groove 170. Accordingly, since the driven cam 212 exhibits a stationary state with respect to the rotating body 116, when the rotating body 116 rotates, the ascending slope 172 </ b> U comes into contact with the descending part 212 </ b> D immediately before the pushing portion 176 reaches the regulating surface 208. As a result, the restricting body 186 is moved downward with respect to the slide plate 144, and thus the restricting surface 208 is retracted into the advance / retreat hole 148 and is located at the retracted position PP. The advancing part 156 does not collide with the regulating surface 208. This state continues while the rotating body 116 further rotates and the retreat continuation portion 212H faces the lower surface of the pushing portion 176. However, when the ascending portion 212U comes into contact with the descending slope 172D, the regulating body 186 is moved upward with respect to the sliding plate 144 by the elastic force of the spring 214, and the regulating surface 208 is moved above the sliding passage 144 above the sliding plate 144. , And is moved to the regulation position CP of the disc 102, so that the entire length of the regulation plate 118 is located in the movement passage 150. This state is performed before the regulating plate 118 is opposed to the through hole 146, and while the retreat continuation portion 212H is opposed to the maintaining portion 172H, and therefore does not interfere with the next moving pushing portion 156. Will be continued.

Next, the reverse-direction pushing portion 158 will be described.
When the rotating body 116 is rotated in the reverse direction, the pushing portion 158 has a function of pushing the disc body 102 located in the through hole 146 and causing the disk body 102 to rotate together with the rotating body 116 in the reverse direction. It is formed on the end face, and in the present embodiment, is constituted by two protrusions formed on the lower surface of the rotating body 116, specifically, an inner reverse rotation pushing portion 158I and an outer reverse rotation pushing portion 158O. . The inner reverse rotation pushing portion 158I is formed by the inner projection 162I, and the outer reverse rotation pushing portion 158O is formed by the rear end surface of the outer projection 162O.
Therefore, the disc body 102 that has fallen into the through hole 146 has the lower surface supported by the substrate 112 (sliding plate 144), the pushing portion 176 at the rear, the pushing portion 158 at the time of reverse rotation at the front, and a circular wall at the outer periphery. While being held by the holding part 160 located just below the through hole 146 and surrounded by the through hole 138, it is rotated by the rotation of the rotating body 116.

Next, the ridge 162 will be described mainly with reference to FIGS.
The ridge 162 has a function of forming a reverse rotation pushing portion 158 that mainly pushes the disc body 102 when the rotating body 116 rotates in the reverse direction, and has a function of reinforcing the rotating body 116 as a secondary function. In the present embodiment, the protrusion 162 includes the inner protrusion 162I and the outer protrusion 162O, and is formed on the lower surface of the rotating body 116 between the three through holes 146, and both have the same configuration. The description will be made on behalf of the first inner ridge 162I and the outer ridge 162O.

First, the inner ridge 162I will be described.
The inner ridge 162I is an arc-shaped ridge having a predetermined width centered on the rotation axis RS of the rotating body 116 and having a center at an inner virtual circle CRI having a radius RI. After the inner concave portion 218I and the outer concave portion 218O are formed, a narrow arc shape is formed, and the rear end at the time of normal rotation is formed to the vicinity of the through hole 146, and the rear end surface is formed. It is a pushing portion 158I at the time of inward reverse rotation. The inner ridge 162I is arranged in the receiving groove 206. Therefore, when the inner ridge 162I is in a positional relationship to the receiving groove 206, the regulating body 186, and thus the regulating surface 208, can be located at the regulating position CP in the moving passage 150.

Next, the outer ridge 162O will be described.
The outer ridge 162O is an arc-shaped ridge having a predetermined width centered on the rotation axis RS of the rotary body 116 and having a radius RO as a center, and the pushing portion 176 has a predetermined width in the forward rotation direction. After that, a narrow arc is formed outside the outer concave portion 218O up to the vicinity of the through hole 146, and the rear end surface is the outer reverse rotation pushing portion 158O. The outer pushing portion 158O and the boundary portion 180 form an outlet opening 218, and the distance between them is slightly larger than the maximum diameter disc 102L (FIG. 4). The outer ridge 162O faces the outer side of the outer regulating surface 208O, and the pushing portion 156 is not formed at this portion.

Next, the depression slope 164 during reverse rotation will be described.
The reverse pressing down slope 164 has a function of retracting the regulating body 186, and thus the regulating surface 208, to the retracted position PP in the advance / retreat hole 148 of the sliding plate 144 when the rotating body 116 is reversed, and in the present embodiment. , The inner concave portion 218I and the outer concave portion 218O are formed by an inner reverse pressing slope 164I and an outer reverse rotating pressing slope 164O formed on end surfaces of the pushing portion 156 side. In other words, the inner-side reverse pressing slope 164I and the outer-side reverse pressing slope 164O are slopes that incline straight from the bottom surfaces of the inner concave portion 218I and the outer concave portion 218O toward the lower surface of the pushing portion 156. With this configuration, when the pushing portion 156 is not opposed to the regulating plate 118, the regulating body 186 is not moved by the driving cam 172, so that the inward reverse pressing slope 164I is located in the inner concave portion 218I, and the outer reverse pressing slope 164O is It is located in the outer recess 218O. In this state, when the rotating body 116 is rotated in the reverse direction, the depressed inclined surface 164I at the time of the inner reverse rotation comes into contact with the inner inclined surface on the back surface of the regulating plate 118, and the depressed inclined surface 164O at the time of the outer reversed rotation contacts the outer inclined surface. The regulating body 186 is pushed down against the force. As a result, the regulating plate 118 is moved to the retreat position PP, so that the rotating body 116 can rotate in the reverse direction without interfering with the pushing portion 156.

Next, the operation of the disc delivery device 100 of the embodiment will be described.
First, a predetermined disk 102, for example, one type of disk 102 or a plurality of types of disk 102, is stored in a disk storage container 114 in a bulk state.
The electric motor 152 is rotated by the dispensing command of the disc 102, and the rotating body 116 is rotated through the speed reducer 154 in the normal rotation direction at the bottom of the disc holding container 114, and in the counterclockwise direction in FIGS. Is done. As a result, the disk body 102 placed on the rotating body 116 is agitated, falls into the through hole 146 in the process of changing its posture variously, and comes into surface contact with the sliding plate 144. In other words, the disk body 102 is located in the movement passage 150. As a result, the disc 102 is pushed by the pushing portion 176 by the continuous rotation of the rotating body 116, and is rotated by the rotating body 116 in the moving passage 150. When the pushing portion 176 is pushed by the pushing portion 176, the pushing portion 176 is formed in an inward arc shape, so that the first contact point P1 of the disc body 102 and the pushing portion 176 is a disc body having a minimum diameter. 102S, which is on the outer peripheral side of the center CC (FIG. 8). As a result, a vector directed from the first contact point P1 toward the rotation axis RS of the rotating body 116 is generated as a component force of the pressing force F1 acting on the disk body 102, so that the sliding pressure against the circular wall 138 can be reduced. This has the effect of suppressing damage to the peripheral surface of the disk body 102 and wear of the circular wall 138.
When the disc 102 is pressed against the inner regulating surface 208I of the regulating plate 118 by the further rotation of the rotating body 116, as shown in FIG. Since the resultant force F3 of the force F2 from the three contact points P3 and the reaction force F2 from the fourth contact point P4 between the inner regulating surface 208I and the disc body 102 goes to the disc body opening 142, the disc body 102 This relationship does not change even when the rotary member 116 is pushed toward the disk body opening 142 and moves to the outer regulating surface 2080, and finally the radial direction of the rotating body 116 passes through the disk body opening 142 by the outwardly extruded portion 178. Is pushed out to the disc guide passage 232 located at the position indicated by. After the disc body 102 is pushed out to the disc body guide passage 232, the rotating body 116 rotates counterclockwise, but before the pushing portion 156 reaches the regulating plate 118, the downward slope 172D of the drive cam 172 is turned off. After pushing down the ascending portion 212U of the driven cam 212, the position is continued by the drive cam retreat continuation portion 172C, so that the regulating plate 118 is moved downward with respect to the sliding plate 144, and the regulating surface 208 is moved to the retreat position PP. While being moved, the retreat position PP is continued while the drive cam retreat continuation part 172C and the maintenance part 172H face each other, so that the regulating plate 118 does not collide with the pushing part 156. Thereafter, when the descending slope 172D faces the evacuation continuation portion 212H from the ascending portion 212U, the regulating plate 118 is pushed up by the urging force of the spring 214 and moves to the regulating position CP, and moves to the regulating position CP while facing the maintaining portion 172H. continue. In other words, immediately after the pushing portion 156 has passed the relative position with respect to the regulating plate 118, the downward slope 172D faces the retreat continuation portion 212H, and the regulating plate 118 is moved to the regulating position CP. At this time, since the inner ridge 162I advances to the receiving groove 206, the regulating plate 118 is moved to the regulating position CP before facing the through hole 146, and the preparation for guiding the next disk body 102 is prepared. For example, when the rotation of the rotator 116 is stopped due to the disk 102, the rotator 116 is rotated in the reverse direction, ie, clockwise in this embodiment. When the rotating body 116 is rotated in the reverse direction, the pressing slope 164 during the reverse rotation contacts the driven portion 210 during the reverse rotation. Specifically, the inner reverse rotation pressing slope 164I contacts the inner reverse rotation driven portion 210I, and the outer reverse rotation pressing slope 164O contacts the outer reverse rotation driven portion 210O to push down the inner reverse rotation driven portion 210I and the outer reverse rotation driven portion 210O. As a result, the regulating plate 118, and thus the regulating surface 208 is moved to the retreat position PP, so that the rotating body 116 can rotate in the reverse direction without interfering with the regulating plate 118.

Next, the operation of the rotating body 116 at the time of reverse rotation will be described with reference to FIG.
When the rotating body 116 rotates in the reverse direction, that is, rotates clockwise, the disk 102 sent out to the disk body guiding passage 232 rotates the rotating disk 132 and finally the curved part rotating disk 132C counterclockwise. As a result, it is forcibly returned to the disc body opening 142. In this case, as shown in FIG. 17A, since the regulating plate 118 is located below the through hole 146, it is located at the regulating position CP, in other words, protrudes into the moving passage 150. When the disc 102 in the disc holding container 114 is located in the through hole 146, the disc 102 is lifted by the movement of the regulating plate 118 to the regulating position CP, and is placed on the sliding plate 144 and the regulating plate 118. A gap larger than the thickness of the disc 102 having the largest thickness is formed between the disc 102 and the corresponding disc 102. In this state, the disc body 102 returning from the disc body guide passage 232 is supported by the distal end of the outer regulating plate 118O and the pushing portion 178. At this time, since the area of the sliding plate 144 formed between the regulating surface 208 and the pressing portion 176 is smaller than the minimum diameter disk 102S, even the minimum diameter disk 102S makes surface contact. It is not possible. Also. Since the center of gravity of the minimum diameter disk 102S pushed up by the restriction plate 118 is located on the restriction plate 118 or at a position farther from the pushing portion 176 than the center of gravity of the minimum diameter disk 102S, the disk 102 A space is formed between the sliding plate 144 and the sliding plate 144 below. Therefore, even when the minimum diameter disk 102S is located in the through hole 146, the end of the minimum diameter disk 102S that has returned from the disk guide passage 232 can advance into this space.
As shown in FIG. 17B, when the rotating body 116 is further rotated clockwise, the distance between the regulating surface 208 and the pushing portion 176 increases. Since the minimum diameter disc 102S returned from the 232 is supported by the tip of the outer regulating plate 118O and the pushing portion 178, the distance between the regulating surface 208 and the pushing portion 176 is smaller than the diameter of the minimum diameter disc 102S. On the other hand, the minimum diameter disc 102S placed on the outer regulating plate 118O cannot make surface contact with the sliding plate 144.
As shown in FIG. 17C, when the rotating body 116 is further rotated in the clockwise direction, the distance between the regulating surface 208 and the pushing portion 176 increases. Since the minimum diameter disc 102S returned from the 232 is supported by the outer regulating plate 118O, the inner regulating plate 118I, and the boundary 180, the distance between the regulating surface 208 and the pushing portion 176 is smaller than the diameter of the minimum diameter disc 102S. Therefore, the minimum-diameter disc body 102S placed on the outer regulating plate 118O cannot make surface contact with the sliding plate 144.
As shown in FIG. 17D, when the rotating body 116 is further rotated in the clockwise direction, the distance between the regulating surface 208 and the pushing portion 176 increases. Since supported by the plate 118I and the pushing portion 176, the minimum diameter disk 102S returned from the disk guide passage 232 is located in the through hole 146, but the returned minimum diameter disk 102S is However, since it is already located in the through hole 146, the minimum diameter disc 102S placed on the outer regulating plate 118O cannot make surface contact with the sliding plate 144. Therefore, the two minimum-diameter discs 102S are not located side by side on the sliding plate 144 below the through hole 146.

Next, with reference to FIG. 1, a disc sending and conveying device 108 using the disc sending device 100 according to the present invention will be described.

It is constituted by a second guide surface 246 and a third guide surface 248 and a fourth guide surface 252 for guiding the front and back surfaces of the disc body 102, respectively. A disc body discriminating device 240 is disposed at the bottom. Specifically, the disc guide passage 232 includes a back guide 254 and a top plate 256. The top plate 256 is detachably attached to the back guide 254 by screws or the like. Further, as shown in FIG. 2 (B), the substrate 112 is inclined by about 45 degrees, and the disc guide path 232 is finally erected. Is configured as a curved portion 260 that curves to the front and back surfaces of the disk body 102.

Next, the first guide surface 244 will be described mainly with reference to FIG.
The first guide surface 244 has a function of guiding one side of the peripheral surface of the disc body 102, and in the present embodiment, is formed on the top plate 256, and is on the left side in front view (in FIG. 3A). , In other words, the guide surface located on the right side in FIG. 3 (B), in which the first arcuate guide surfaces 258 and the first chevron guide surfaces 262 are alternately arranged. That is, the first mountain-shaped guide surface 262 is formed by an upstream first inclined surface 262I inclined forward and upward to the left and a downstream first inclined surface 262O located downstream and inclined forward and upward to the right. Make up the part.

Next, the second guide surface 246 will be described.
The second guide surface 246 has a function of guiding the other side of the peripheral surface of the disc body 102, and in the present embodiment, is formed opposite to the first chevron guide surface 262 formed on the top plate 256. A second arcuate guide surface 264 and a second chevron guide surface 266 formed opposite to the first arcuate guide surface 258. The second arcuate guide surface 264 is curved upwardly to the left, then extends substantially vertically upward, and then forms a lateral concave portion curved upwardly to the right.
The second mountain-shaped guide surface 266 has a right-sided mountain-shaped protrusion formed by an upstream second inclined surface 266I inclined forward and upward to the right and a downstream second inclined surface 266O located downstream and inclined forward and upward to the left. Make up the part.
Therefore, the first guide surface 244 and the second guide surface 246 define a passage having a predetermined width and regularly undulating right and left in a front view.

Next, the third guide surface 248 will be described.
The third guide surface 248 has a function of determining the back surface of the disc guide passage 232, in other words, a function of guiding the surface of the disc 102, specifically, the front or back surface of the disc 102. In the present embodiment, it is constituted by the surface of an elongated flat plate 250 having a predetermined thickness. As shown in FIG. 2B, the third guide surface 248 is formed in a portion corresponding to the curved portion 260 so as to be concave in an arc shape with a predetermined radius with respect to the front and back surfaces of the disk body 102. .

Next, the fourth guide surface 252 will be described.
The fourth guide surface 252 has a function of determining the front surface of the disc guide passage 232, in other words, a function of guiding the surface of the disc 102, specifically, the front or back surface of the disc 102. In this embodiment, the top plate 256 is formed of an elongated flat plate made of a transparent resin. The portion corresponding to the curved portion 260 of the fourth guide surface 252 is formed so as to be convex with respect to the front and back surfaces of the disc 102 at a radius smaller than that of the third guide surface 248.
Therefore, three surfaces of the first guide surface 244, the second guide surface 246, and the fourth guide surface 252 of the disc guide passage 232 are formed on the top plate 256, and the first guide surface 244 and the second guide surface 246 are formed. Are formed slightly larger than the maximum diameter disk body 102 to be used and less than twice the diameter of the minimum diameter disk body 102, and the third guide surface 248 and the fourth guide surface The distance from the thinner disk 252 is slightly larger than the thickness of the thinnest disk 102 and less than twice the thickness of the thinnest disk 102. In other words, as long as the disk body guide passage 232 is within the diameter and thickness of the disk body 102 that is assumed to be used, the two disk bodies 102 do not overlap in the diameter direction or the thickness direction. Is configured. Further, in the curved portion 260, the distance between the fourth guide surface 252 and the third guide surface 248 is set larger than other portions so that the disk body 102 having the maximum thickness can pass. This is because the disc body 102 comes into contact with the third guide surface 248 in the curved portion 260 at the front end and the rear end in the traveling direction, and the intermediate portion is separated from the third guide surface 248, so that the thickness of the disc body 102 is reduced. This is because it increases in appearance.

Next, the transport mechanism 242 will be described.
The transport mechanism 242 has a function of transporting the disk body 102 in the disk body guide passage 232 from the inlet 228 to the outlet 106. It is configured.

First, the base body 268 will be described.
The base body 268 has a function of supporting the elongated flat plate 250, the top plate 256, the driving device 272, and the turntable 132. In the present embodiment, the lower end is fixed to the frame 122 and extends upward. It is constituted by a plate-shaped body made of sheet metal.

Next, the driving device 272 will be described.

Next, the gear train 274 will be described mainly with reference to FIGS.
The gear train 274 has a function of transmitting the rotation output of the electric motor 152 and thus the reduction gear 154 to the turntable 132 and rotating them. In the present embodiment, the rotator gear rotated integrally with the rotator 116 274R, a curved gear 274C meshing with the rotating gear 274R, a first rotating gear 274F meshed with the curved gear 274C, and an integral rotating disk identical to the rotating gear 274S integrally formed with the first rotating gear 274F. It is composed of a gear 274FS and a rotary disk gear 274S that meshes with the integral rotary disk gear 274FS. That is, the electric motor 152 sequentially rotates the rotating body gear 274R, the bending portion gear 274C, the first rotating disk gear 274F, the integrated rotating disk gear 274FS, and the rotating disk gear 274S via the speed reducer 154. The rotation ratio between the rotating body gear 274R and the bending gear 274C is 1: 1.5, the rotation ratio between the bending gear 274C and the first rotating disk gear 274F, and the rotation between the first rotating disk gear 274F and the rotating disk gear 274S. The ratio is one to one. Therefore, since the bending portion rotating disk 132C makes 1.5 rotations while the rotating body 116 makes one rotation, the through-hole 146 and the disc body passage 284C are rotated in a predetermined phase relationship, and the bending portion rotating disk 132C, The first turntable 132F and the reference turntable 132S are always rotated in the same phase in a one-to-one speed ratio relationship. In other words, the disc body 102 pushed out by the pushing part 178 by the rotation of the rotating body 116 advances to the disc body guide passage 232, and the curved part first disc body pusher 234C or the curved part second disc body. It can be moved to the disc guide path 232 by the pusher 236C, and in the disc guide path 232, a curved portion first disc pusher 234C, a curved second disc pusher 236C, and The first rotating disc first disc pushing member 234F, the first rotating disc second disc pushing member 236F, the first disc pushing member 234, and the second disc pushing member 236 sequentially and positively convey.

In the present embodiment, the turntable 132C has a curved portion. Although the first turntable 132F and the reference turntable 132S are used, the structure described below is common to all the turntables, and therefore, the reference turntable 132S will be described as a representative.

  The reference rotating disk 132S is used for a planar disc guide passage 232, and circular reference rotating disks 132S having a first disc pushing member 234 and a second disc pushing member 236 are arranged at predetermined intervals. Is established. The reference turntables 132S are rotatably provided about an axis orthogonal to the base body 268 and, thus, the disc body guide passage 232, and their surfaces 273 are substantially flush with the third guide surface 248. It is configured as follows. The reference rotating disk 132S of the present embodiment is provided rotatably around an axis near the top of the first angled guide surface 262 or the second angled guide surface 266, and includes a first disk body pusher 234 and a second disk body. The pusher 236 is arranged point-symmetrically with respect to the axis. In the case where the first disc pushing member 234 and the second disc pushing member 236 are made of resin, it is preferable to cover a portion for pushing the disc 102 with sheet metal in order to prevent abrasion. . Further, the distal ends of the first disc pushing member 234 and the second disc pushing member 236 are inserted into an annular groove 276 formed in the top plate 256, and the disc 102 is moved by the first disc pushing member 234. Alternatively, it is configured so as not to fall off from the second disk pushing member 236. A spur gear 280 is integrally provided on the peripheral surface of the reference rotating disk 132S, and the gears of the adjacent reference rotating disks 132S mesh with each other. The reference rotating disk 132S is rotated at a rotation speed 1.5 times the rotation speed of the rotating body 116. All the rotating disks 132 are rotated at the same speed, and the rotating disks 132 that are adjacent to each other are rotated in directions opposite to each other, and the first disk pressing member 234 and the second disk pressing member 236 are fixed at a predetermined speed. Are rotated in a phase relationship of Although the above description has the same basic function and structure in all the rotating disks 132, the bending portion rotating disk 132C facing the bending portion 260 and the first rotating disk 132F adjacent thereto are different from the reference rotating disk 132S. Since there is a difference in the detailed structure, the difference will be described below.

First, the bending portion rotary plate 132C will be described.
The bending portion rotating disk 132C has a function of sending out the disk bodies 102 sent from the disk body sending device 100 one by one to the next first rotating disk 132F, and the bending portion provided on the bending portion rotating disk 132C. The lengths of the first disc pushing member 234C and the curved portion second disc pushing member 236C are longer than those of the first disc pushing member 234 and the second disc pushing member 236 of the reference turntable 132S. The tips are pivotable in a curved portion annular groove 276C formed in the curved portion top plate 256C. The circumferential lengths of the curved portion first disc body pusher 234C and the curved portion second disc body pusher 236C in the curved portion turntable 132C are determined by their rotational front end 278C and rotational rear end 282C. The spacing, and hence the disc body passage 284C, is formed slightly larger than the spacing through which the largest diameter disc body 102 can pass, and the curved portion first disc pushing member 234C and the curved portion second disc pushing member 236C. Has a continuous arc shape except for the disc-shaped passage 284C. When the bending portion first disc body pusher 234C and the bending portion second disc body pusher 236C are integrated with the bending portion turntable 132C in an arc, there is an advantage that they can be strengthened. The curved portion first chevron guide surface 262C facing the curved portion rotating disk 132C is formed to protrude from the substrate 112. The substrate 112 also has a curved second arcuate guide surface 264C facing the curved first mountain-shaped guide surface 262C. Further, the curved portion top plate 256C facing the curved portion first chevron guide surface 262C and the curved portion second arcuate guide surface 264C is formed in a curved plate shape, and the curved portion guide surface 286 facing the surface 273 is formed.

The heights of the first disc pushing member 234F and the first rotating disc second disc pushing member 236F are slightly higher than those of the reference rotating disc 132S, but the bending portion first disc pushing member 234C and the bending portion have the same height. It is formed lower than the two-disc pusher 236C. This is because the disc guide passage 232 is curved in the vicinity of the curved part rotating disk 132C (the hatched portion in FIG. 4A). A chamfered portion 288 is formed on the outside of the distal end portion of the first rotary disk first disk body pusher 234F and the first rotary disk second disk body pusher 236F of the first rotary disk 132F. This is for avoiding the interference between the bending portion first disk body pusher 234C and the bending portion second disk body pusher 236C in the bending portion rotating disk 132C.

  In the present embodiment, as shown in FIG. 3, the outlet-portion first chevron guide surface 262 </ b> E facing the final turntable 132 </ b> E closest to the outlet 106 is the first upstream chevron guide surface 262 on the upstream side. Although the angle formed between the slope 262I and the first downstream slope 262O is large, this case is also included in the chevron guide surface. Further, in the present embodiment, the disc guide passage 232 is formed in the vicinity of the outlet 106 as an outlet guide passage 232E slightly lower than horizontal.

When the light from the light emitting unit is received at the light receiving unit, the disk unit 102 is determined to be the disk body 102 having the central hole. However, the central hole detection sensor 330 may be configured by another method. Can also. By detecting the presence or absence of the central hole in a state where the disc 102 has begun to be extruded, there is an advantage that an abnormality of the disc 102 that has been dispensed can be detected.

Next, the pulse signal generator 304 will be described mainly with reference to FIG.
The pulse signal generating section 304 has a function of outputting a pulse signal PS in conjunction with the movement of the moving section 302. In this embodiment, the pulse signal generating section 304 includes at least an oscillator 336 and a sensor 338. However, the swinging body 336 is not limited to the swinging body 336, and can be changed to a linear reciprocating body.

Next, the oscillator 336 will be described.
The oscillating body 336 has a function of oscillating in conjunction with the movement of the moving unit 302 and a function of forming a detecting unit 292 so as to output a pulse signal based on detection of the sensor 338 for each predetermined oscillating amount. In the present embodiment, a pot-shaped detection object 342 formed in a cylindrical shape with a bottom is made of a light-transmitting transparent resin. The detection object 342 is configured to be rotatable about the fixed shaft 308 and to swing integrally with the swing lever 312.

Next, the detected object 342 will be described.
The detection target 342 has a cylindrical cylindrical portion 342P connected to an outer peripheral edge of a disk-shaped bottom portion 342B, and the center of the bottom portion 342B is disposed on the axis SL of the fixed shaft 308. As shown in FIGS. 14 (B), (C), (D) and (E), the cross section of the cylindrical portion 342P is trapezoidal and parallel to the axis SL. A certain non-detection portion 344 and a plate-shaped detection portion 346 disposed between a rising slope and a falling slope are formed at predetermined intervals. The non-detection part 344 is a part that exhibits a function that is not detected in relation to the sensor 338, and the detected part 346 is a part that exhibits a function that is detected in relation to the sensor 338. Therefore, when the sensor 338 is the optical sensor 348, the detected portion 346 may have a structure in which the light projected from the light projecting portion 348P reaches the light receiving portion 348R without being flat. In this embodiment, since the sensor 338 is an optical sensor, the non-detection section 344 is formed on a slope having an angle of 45 degrees with respect to the projection light, and the projection light from the projection section 348P is reflected by the slope. The detected part 346 functions as a non-detecting part 344 because it is deviated from the light receiving part. Since the detected part 346 has a flat plate shape, light can be transmitted linearly and reach the light receiving part 348R. Demonstrate function. Specifically, as shown in FIG. 14B, a first detected portion 346L that is a lower flat plate portion, a first non-detected portion 344L, a second detected portion 346H that is a higher flat plate portion, and The second non-detection portions 344R are repeatedly arranged at the same pitch, in other words, at equal intervals, in the order of the second non-detection portions 344R, and have the same length in the circumferential direction. Further, in relation to a sensor 338 described later, the projection light of the pair of sensors 338 simultaneously emits the same first detected portion 346L, first non-detected portion 344L, second detected portion 346H, or second non-detected portion. 344R is set so as not to project light. Therefore, when an optical sensor is used as the sensor 338, a detection target 342 having a similar function can be used. For example, as the non-detection unit 344, a tape through which light is not transmitted may be attached, colored, or formed on the surface. The number of pairs of the detected part 346 and the non-detected part 344 is preferably provided as large as possible in order to determine the accuracy in detecting the diameter of the disc 102. However, due to physical restrictions on manufacturing, at least 360 degrees require 180 pairs or more, but preferably 300 pairs or more.

Next, the sensor 338 will be described.
The sensor 338 has a function of outputting the pulse signal PS in cooperation with the non-detection part 344 of the detection target 342 and the detection target 346. In the present embodiment, the sensor 338 is configured by the optical sensor 348 and has a cylindrical part 342P. And a light receiving section 348R disposed outside the cylindrical section 342P and capable of receiving light emitted from the light projecting section 348P. The light projecting part 348P and the light receiving part 348R are arranged at a predetermined distance from each other in the circumferential direction of the cylindrical part 342P, and the first light projecting PL1 from the first light projecting part 348P1 receives the first detection signal PS1. The second light emitting portion 348R2 that outputs the second detection signal PS2 is configured to enter the second light receiving portion 348R2 that outputs the second detection signal PS2. Therefore, the first light projecting section 348P1 and the first light receiving section 348R1 constitute a first detecting section 3491, and the second light projecting section 348P2 and the second light receiving section 348R2 constitute a second detecting section 3492. The first light emission PL1 and the second light emission PL2 are parallel lights. In addition, the predetermined distance means that the light is not projected on the same first detected portion 346L, the first non-detected portion 344L, the second detected portion 346H, or the second non-detected portion 344R at the same time, and the first detected portion is not detected. The distance between the signal PS1 and the second detection signal PS2 is such that the rising edge and the falling edge are shifted and satisfy the output state shown in FIG. The meaning of the predetermined distance is detected by the disc body determination unit 294 based on the output from the first detection unit 3491 and the second detection unit 3492, in other words, the output from the first light receiving unit 348R1 and the second light receiving unit 348R2. By exerting a function of determining whether the rotation direction of the body 342 is counterclockwise or clockwise in FIG. 14A, and exerting a function indicating the rotation angle of the cylindrical portion 342P. is there. In the present embodiment, when the first light projection PL1 from the first light emitting unit 348P1 passes through the detected part 346 (the first detected part 346L or the second detected part 346H), the first light PL1 is The first light receiving portion 348R1 receives light, and the second light emitting portion PL2 from the second light emitting portion 348P2 is received by the non-detecting portion 344 (the first non-detecting portion 344L or the second non-detecting portion 344R) by the second light receiving portion 348R2. Not done.

The rotation direction of the cylindrical portion 342P is determined on the basis of the first detection signal PS1 from the second detection portion 3492 and the second detection signal PS2 from the second detection portion 3492 (the second light receiving portion 348R2).

A method of determining the rotation direction based on the first detection signal PS1 and the second detection signal PS2 in the moving direction determination unit 360 will be described with reference to FIGS. In the following description, the output “L” indicates a state where the output level of the first detection signal PS1 or the second detection signal PS2 as a pulse signal is relatively low, and the output is “H”. , The output level of the first detection signal PS1 or the second detection signal PS2 as a pulse signal is relatively high. In FIG. 14, the detection target 342 is rotated in the counterclockwise direction by the front arcuate portion FC on the front side in the traveling direction of the disk 102, which is the first half of the time when the disk 102 passes through the detection unit 292. 15A), in other words, in FIG. 14B, when the cylindrical portion 342P moves to the left of the arrow X, in other words, in the first movement direction X, the first light receiving portion 348R1 The relative position shifts from the second non-detection section 344R to the first detection section 346L, or from the first non-detection section 344L to the second detection section 346H, and the second light receiving section 348R2 moves from the first detection section 346L to the first detection section 346L. The relative position moves from the non-detection part 344L or the second detected part 346H to the second non-detection part 344R. Thereby, as shown in the X direction column 350X in FIG. 15C, the process is shifted from the first non-detection section 344L to the second detection section 346H or from the second non-detection section 344R to the first detection section 346L. At this time, the first light receiving unit 348R1 outputs the first pulse PS1 rising signal RE1 (indicated by an upward arrow in FIG. 15C), and the output of the second light receiving unit 348R2 is L. When shifting from the one detected portion 346L to the first non-detected portion 344L or the second detected portion 346H to the second non-detected portion 344R, the first light receiving portion 348R1 outputs a first pulse falling signal FE1, Further, the output of the second light receiving unit 348R2 is H, and the second light receiving unit 348R2 shifts from the first non-detecting unit 344L to the second detected unit 346H or from the second non-detecting unit 344R. When shifting to the first detected portion 346L, the output of the second light receiving portion 348R2 outputs the second pulse rising signal RE2, and the output of the first light receiving portion 348R1 is H, and the output from the second detected portion 346H is When shifting from the second non-detection unit 344R or the first detected unit 346L to the first non-detection unit 344L, the second light receiving unit 348R2 outputs the second pulse falling signal FE2, and the first light receiving unit 348R1 Is L. On the other hand, in the second half of the time when the disc 102 passes through the detection unit 292, the reverse second movement when the pusher 302 pushes the rear arc-shaped portion BC on the rear side in the traveling direction of the disc 102. When moved to the right in the direction Y, the first light receiving portion 348R1 is relatively positioned from the first non-detecting portion 344L to the first detected portion 346L or from the second non-detecting portion 344R to the second detected portion 346H. As shown in the Y direction column 350Y in FIG. 15C, the first non-detecting section 344L shifts to the first detected section 346L, or the second non-detecting section 344R shifts to the second detected section 346H. At this time, the first light receiving unit 348R1 outputs the first pulse rising signal RE1 and the output of the second light receiving unit 348R2 is H, and the first detected portion 346L to the second non-detection portion 344R or the second 2 From the detected part 346H to the first non- When shifting to the sensing unit 344L, the first light receiving unit 348R1 outputs the first pulse falling signal RF1, and the output of the first light receiving unit 348R1 is L, and the second non-detecting unit 344R outputs the second signal. When shifting to the detected portion 346H, or when shifting from the first non-detecting portion 344L to the first detected portion 346L, the second light receiving portion 348R2 outputs the second pulse rising signal RE2, and When the output of the light receiving unit 348R1 is L, the second light receiving unit shifts from the second detected unit 346H to the first non-detecting unit 344L, or shifts from the first detected unit 346L to the second non-detecting unit 344R. 348R2 outputs the second pulse signal falling signal RE2, and the output of the first light receiving section 348R1 is H. As described above, by determining the output contents of the first detection signal PS1 and the second detection signal PS2, it is possible to detect the rotation direction of the cylindrical portion 342P, that is, the rotation direction of the detection target 342.
More specifically, in FIG. 3A, when the moving unit 302 (the roller 314) is rotated in the counterclockwise direction by the disk 102, the detected object 342 is moved in the counterclockwise direction in FIG. (B) to (E), and is moved in the first movement direction X. Therefore, since the first combination of the output signals from the first light receiving unit 348R1 and the second light receiving unit 348R2 is one of the X direction columns 350X in FIG. 15C, it is in the first half of the passage through the disc 102. Can be determined. On the other hand, when the disk body 102 is flipped out by the roller 314, the detection target 342 is rotated clockwise in FIG. 14A, so that the cylindrical portion 342P is moved in the second movement direction Y in FIG. . Therefore, since the combination of the output signals from the first light receiving unit 348R1 and the second light receiving unit 348R2 is any of the Y direction columns 350Y in FIG. 15C, the disc 102 passes through in FIG. It can be determined that it is in the latter half of the process.

Next, the subtraction unit 362 will be described.
In the present embodiment, the subtracting unit 362 determines whether the moving direction from the first moving direction X to the second moving direction Y from the first moving direction X by the moving direction discriminating unit 360 is based on the count value Cnt stored in the edge counting unit 358. After the change, the first pulse rising edge signal PSR1 based on the first pulse signal PS1, the first pulse falling edge signal PSF1, the second pulse rising signal RE2 based on the second pulse signal PS2, and the second pulse falling edge signal It has a function of subtracting 1 each time the PSF2 is output. However, the subtraction unit 362 counts the first pulse rising edge signal PSR1, the first pulse falling edge signal PSF1, the second pulse rising signal RE2, and the second pulse falling edge signal PSF2 in the second movement direction Y. In addition, when a payout signal DS described later is output, the count value in the subtraction unit 362 is subtracted from the count value Cnt in the count unit 359, and the value after the subtraction is compared with the reference value PN as the maximum count value MC. You may.

Next, the reference value storage unit 363 will be described.
The reference value storage unit 363 has a function of storing a reference value PN for comparing with the maximum count value MC stored in the maximum count value storage unit 372 in order to determine whether the disc body 102 has a predetermined diameter. The reference value may be one, a plurality, or a number defining a predetermined range. In the present embodiment, the edge reference value storage unit 364 has that function.
The edge reference value storage unit 364 has a function of storing a reference value PN for comparison with a count value Cnt in the edge counter 358 serving as a reference for determining whether the disc body 102 has a predetermined diameter. In this embodiment, one reference value, for example, 100 is stored.

Next, the maximum count value storage unit 372 will be described.
The maximum count value storage unit 372 has a function of storing the maximum count value MC of the count value Cnt counted in the edge count unit 358, that is, the count unit 359. Therefore, when the disc body 102 is sent out without the rotating body 116 being reversed, the count value Cnt and the maximum count value MC are the same, but while the rotating body 116 is being reversed, and Becomes a different value up to halfway in the case of normal rotation again.

Next, the determination unit 366 will be described.
The determination unit 366 is based on the maximum count value MC (the count value Cnt in the edge count unit 358) stored in the maximum count value storage unit 372 at the time when the payout signal DS as the detection signal from the passage sensor 290 is output. And has a function of determining whether the diameter is a predetermined diameter. That is, since the fixed portion 298 is fixed and the moving portion 302 is stationary at a position separated from the fixed portion 298 by a predetermined distance, when the moving portion 302 is moved by a predetermined amount by the First pulse rising edge output from PS1 rising edge detecting section 354 based on each of first pulse signal PS1 output from first light receiving section 348R1 and second pulse signal PS output from second light receiving section 348R2. The first pulse falling edge signal PSF1 output from the signal PSR1, PS1 falling edge detection section 355, the second pulse rising edge signal PSR2 output from the PS2 rising edge detection section 356, and the output from the PS2 falling edge detection section 358. Of the second pulse falling edge signal PSF2 This is output at a predetermined timing by a predetermined number, and the first pulse rising edge signal PSR1, the first pulse falling edge signal PSF1, the second pulse rising edge signal PSR2, and the second pulse falling edge signal PSF2 are sequentially counted. By comparing the maximum count value MC of the count value Cnt with the reference value PN, it is possible to indirectly detect the diameter of the disc 102 and determine whether the disc 102 is a suitable disc. In the case of a disc 102 having a diameter, for example, a 100 yen coin of Japanese yen is used as the disc 102, and if a 10 yen coin is mixed by mistake, the diameter of the 100 yen coin is 22.6. Since the diameter of a 10-millimeter coin is 23.5 millimeters, a difference of 0.9 millimeter is applied to the first pulse based on the first pulse signal PS1. Judgment is made based on the numbers of the rising edge signal PSR1, the first pulse falling edge signal PSF1, and the second pulse rising edge signal PSR2 and the second pulse falling edge signal PSF2 based on the second pulse signal PS2. An abnormal signal ES1 is output. If the discrimination accuracy of the diameter of the disc 102 may be low, the first pulse rising edge signal PSR1, the first pulse falling edge signal PSF1, the second pulse rising edge signal PSR2, or the second pulse falling edge. Any one or more of the signals PSF2 are selected and counted, and can be used as a count value Cnt.

Next, the disc unit 368 with holes will be described.
When receiving the hole detection signal HS from the center hole detection sensor 330 (FIG. 3), the disc unit with hole 368 discriminates that it is the disc with hole 102H, and the disc with hole 102H is inappropriate. , The second abnormal signal ES2 is output. For example, when a 100 yen coin having a diameter of 22.6 mm is used and a 5 yen coin having a diameter of 22.0 mm is mixed by mistake, an abnormality is notified.

Next, the reset unit 370 will be described.
The reset unit 370 has a function of resetting the count value Cnt in the count unit 359 and the maximum count value MC in the maximum count value storage unit 372 to 0 based on the payout signal DS from the passage sensor 290. In, the subtractor 362 is also reset, and is configured by software.

Next, the maximum count value storage unit 372 will be described.
The maximum count value storage unit 372 has a function of storing the maximum count value MC of the count value Cnt counted in the edge count unit 358, that is, the count unit 359. Therefore, when the disc body 102 is sent out without the rotating body 116 being reversed, the count value Cnt and the maximum count value MC are the same, but while the rotating body 116 is being reversed, and Becomes a different value up to halfway in the case of normal rotation again.

Next, the operation of the disc determination unit 294 will be described with reference to the flowchart of FIG.
First, a subroutine process for calculating the diameter of the disc 102 will be described with reference to FIGS.
First, when the moving unit 302 is moved in a direction away from the fixed unit 298 by the disc body 102, in other words, the front arc part FC on the front side in the traveling direction of the disc body 102 is fixed to the fixed unit 298 and the moving unit 302. 14A, the detected portion 342P is rotated in the counterclockwise direction in FIG. 14A, and thus is moved in the arrow X direction in FIG. 14B. Thus, as described above, as shown in FIG. 15A, the first pulse signal PS1 and the second pulse signal PS2 are output from the first light receiving unit 348R1 and the second light receiving unit 348R2, respectively. The first pulse signal PS1 and the second pulse signal PS2 rise with a time difference TRU. In this case, as described above, the first pulse signal PS1 from the first light receiving unit 348R1 and the second pulse signal PS2 from the second light receiving unit 348R2 have an output relationship in the X direction column 350X in FIG. 15C. Become. On the other hand, when the moving unit 302 approaches the fixing unit 298 in order to flip out the disc body 102, in other words, the rear arc-shaped part BC on the rear end side in the traveling direction of the disc body 102 moves with the fixing unit 298. 15B, after the second pulse signal PS2 is output, the first pulse signal PS1 is output with a predetermined time difference TRD as shown in FIG. 15B, and as shown in FIG. The output relationship is in the Y direction column 350Y.
Therefore, in step S11 in the subroutine process, the output from the first light receiving unit 348R1 is the first pulse rising signal RE1 of the first pulse signal PS1, and the output from the PS1 rising edge detection unit 354 is the first pulse rising edge signal PSR1 ( It is determined whether the output of the second pulse signal PS2 from the second light receiving unit 348R2 is “L”. If the output is a combination of these, the process proceeds to step S15, and the combination is performed. If not, the process proceeds to step S12.
In step S12, the output from the first light receiving unit 348R1 is the first pulse falling signal FE1 of the first pulse signal PS1, and therefore, the output from the PS1 falling edge detection unit 355 is the first pulse falling edge signal PSF1 (FIG. 13 is indicated by a downward arrow), and whether the output of the second pulse signal PS2 from the second light receiving unit 348R2 is “H”, and if it is a combination of these, the process proceeds to step S15, and the combination is not these. In this case, the process proceeds to step S13.
In step S13, the output from the second light receiving unit 348R2 is the second pulse rising edge signal RE2 of the second pulse signal PS2, and therefore, the output from the PS2 rising edge detection unit 356 is the second pulse rising edge signal PSR2 and the first pulse rising edge signal PSR2. It is determined whether the output of the first pulse signal PS1 from the light receiving section 348R1, that is, the first light receiving section 348R1 is "H", and if the combination is a combination of these, the procedure proceeds to step S15. If not, the procedure proceeds to a step S14. .
In step S14, the output of the second pulse signal PS2 from the second light receiving unit 348R2 is the second pulse falling signal FE2, and therefore, the output from the PS2 falling edge detection unit 357 is the second pulse falling edge signal PSF2, and It is determined whether the output of the first pulse signal PS1 from the first light receiving section 348R1 is "L". If the output is a combination of these, the process proceeds to step S15, and if not, the process proceeds to step S18.
In step S15, the counting section 359 (edge counting section 358) counts “1” as the count value Cnt, and then proceeds to step S16.
In step S16, "1" of the count value Cnt in the edge counting unit 358 is compared with the maximum count value MC. If the count value is small, the first routine process ends. If the count value is large, the process proceeds to step S17. In this case, since the maximum count value MC is 0 and the count value in step S15 is 1, the process proceeds to step S17.
In step S17, the count value Cnt in step S15 is stored in the maximum count value storage unit 372 as a new maximum count value MC, and then the first routine process ends.
As described above, the process that reaches step S15 is that the output of the first light receiving unit 348R1 is the first pulse rising signal RE1 and the output of the second light receiving unit 348R2 is “L”, and then the first light receiving unit The output of 348R1 is the first pulse falling edge signal FE1, the output of the second light receiving section 348R2 is "H", the output of the second light receiving section 348R2 is the second pulse rising signal RE2, and In this case, the output of the first light receiving unit 348R1 is "H", the output of the second light receiving unit 348R2 is the second pulse falling signal FE2, and the output of the first light receiving unit 348R1 is "L". .
When the disk body 102 further moves the moving unit 302 away from the fixed unit 298, the processing of steps S11 to S17 is repeated. At the time of this repetition, one of the signal states occurs, so “1” is further added to the count value Cnt stored in the edge counting unit 358 again in step S15, and the sum after the addition is added in step S16. When the numerical value Cnt is larger than the maximum count value MC stored in the maximum count value storage unit 372, the process proceeds to step S17, and is stored in the maximum count value storage unit 372 as a new maximum count value MC.
On the other hand, in step S18, the output of the first pulse signal PS1 from the first light receiving unit 348R1 is the first pulse rising signal RE1, and the output from the PS1 rising edge detection unit 354 is the first pulse rising edge signal PSR1, and It is determined whether or not the output of the second pulse signal PS2 from the second light receiving unit 348R2 is “H”. If the combination is a combination of these, the process proceeds to step S22; otherwise, the process proceeds to step S19.
In step S19, the output of the first pulse signal PS1 from the first light receiving unit 348R1 is the first pulse falling signal FE1, and the output from the PS1 falling edge detection unit 355 is the first pulse falling edge signal PSF1, and , It is determined whether the second pulse signal PS2 from the second light receiving unit 348R2 is “L”. If the second pulse signal PS2 is a combination of these, the process proceeds to step S22. If not, the process proceeds to step S20.
In step S20, the output of the second pulse signal PS2 from the second light receiving unit 348R2 is the second pulse rising signal RE2, and therefore, the output from the PS2 rising edge detection unit 356 is the second pulse rising edge signal PSR2 and the first pulse rising edge signal PSR2. It is determined whether or not the output of the first pulse signal PS1 from the light receiving section 348R1 is "L". If the combination is a combination of these, the process proceeds to step S22. If not, the process proceeds to step S21.
In step S21, the output of the second pulse signal PS2 from the second light receiving unit 348R2 is the second pulse falling signal FE2, therefore, the second pulse falling edge signal PSR2 from the PS2 falling edge detection unit 357, and It is determined whether the first pulse signal PS1 from the one light receiving section 348R1 is “H”. If the first pulse signal PS1 is a combination of these, the process proceeds to step S22. If not, the routine process is terminated.
Here, the conditions of steps S18 to S21 are satisfied in the case of the Y direction column 350Y in FIG. 15C. In other words, this is a case where the moving unit 302 moves in a direction approaching the fixed unit 298. In other words, the moving unit 302 is pushing the rear arc-shaped portion BC on the rear side in the traveling direction of the disc 102, that is, the disc 102 is being dispensed.
In this case, in step S22, it is determined whether or not the count value Cnt in the edge counting unit 358 is 1 or more. If the count value is not 1 or more, the routine process ends. If it is 1 or more, the process proceeds to step S23.
In step S23, after subtracting “1” from the count value Cnt in the edge counting unit 358, the count value Cnt after the subtraction is stored in the edge counting unit 358, and then the process proceeds to step S24.
In step S24, it is determined whether or not the hole detection signal HS from the center hole detection sensor 330, that is, the second abnormal signal ES2 from the holed disc body determination unit 368 is output. If not, the routine process is terminated and determined. In this case, the process proceeds to step S25.
In step S25, if the second abnormal signal ES2 has been output, the inappropriate disk signal UCS is output, and the routine processing ends. It should be noted that, based on the inappropriate disk signal UCS, the related device performs processing on the inappropriate disk 102.
When the normal dispensing of the disc 102 is performed normally, the processing of steps S18 to S24 is repeated, and in step S23, the count value Cnt in the edge counting unit 358 is sequentially reduced by “1”, and finally “0”. , And when the payout signal DS is output from the passage sensor 290, the processing after step S4 in the main routine is performed.

Next, the main routine processing in FIG.
In step S1, it is determined whether the signal from the passage sensor 290 is "L". If the signal from the passage sensor 290 is not “L”, in other words, step 1 is looped while the disc 102 is being detected by the passage sensor 290, that is, while the payout signal DS is being output. If the payout signal DS from the passage sensor 290 is a nonexistent signal "H", in other words, if the disc 102 is not detected by the passage sensor 290, the process proceeds to step S2.
In step S2, the count value Cnt in the counting section 359 (edge counting section 358) and the maximum count value MC in the maximum count value storage section 372 are initialized (reset to zero), and the process proceeds to step S3.
In step S3, a subroutine process shown in FIG. 13B is executed, and the process proceeds to step S4.
In step S4, it is determined whether the count value Cnt of the edge counting unit 358 is a predetermined value, for example, “0”. If the count value Cnt is larger than “0”, the process returns to step S3 to execute a subroutine process. When the count value Cnt is “0”, the process proceeds to step S5. The predetermined value is not limited to “0” and may be a value close to “0”. This is because if the accuracy of the disc body determination unit 294 is high, it may not return to the initial position due to play of a mechanical part or the like.
In step S5, it is determined whether the signal from the passage sensor 290 is "L", in other words, whether the passage sensor 290 has detected the disc 102 and has output the payout signal DS with the output "L", and pays out. When the signal DS is not output, the process returns to step S3. On the other hand, when the signal from the passage sensor 290 is “L”, in other words, the disk body 102 is flipped out by the moving unit 302 and detected by the passage sensor 290, and When the output becomes "L", the process proceeds to step S6.
In step S6, the maximum count value MC stored in the maximum count value storage unit 372 is transmitted to the determination unit 366, and the process proceeds to step S7.
In step S7, the determination unit 366 determines whether the paid-out disk 102 is an appropriate disk 102. Specifically, when the maximum count value MC matches the reference value PN stored in the reference value storage unit 363 (edge reference value storage unit 364), or when the maximum count value MC is within the set range, the process returns to step S1. If they do not match, or are not in the set range, the process proceeds to step S8.
In step S8, the determination unit 366 outputs the first abnormal signal ES1, in other words, the inappropriate disc signal UCS, and then returns to step S1.
The improper disc signal UCS is used for processing the improper disc 102 in a device that uses the paid-out disc 102.

Next, a special case will be described with reference to FIG.
As shown in FIG. 18 (A), this is a case where the disk 102 returns in the middle of dispensing the disk 102 as shown in FIG. 18 (B). That is, when the disc 102 bites in the disc sending device 100, the rotating body 116 is reversed to eliminate the biting. By this reversal, the disc 102 in the transport device 104 is also returned, so that the moving unit 302 is stopped at the original rest position in the buffer 328 without discharging the disc 102 by the return movement of the disc 102. After being returned to, it may be pushed again and paid out as shown in FIG.
In this case, in the state of FIG. 18A, the moving portion 302 is separated from the fixed portion 298 by the front arc-shaped portion FC on the front side in the traveling direction of the disk body 102, and thus the moving portion 302 is described above in the description of the X direction column 350X. As described above, when the output of the first light receiving unit 348R1 is the first pulse rising signal RE1 and the output of the second light receiving unit 348R2 is "L", the output of the first light receiving unit 348R1 falls the first pulse. When the signal is FE1 and the output of the second light receiving unit 348R2 is “H”, the output of the second light receiving unit 348R2 is the second pulse rising signal RE2, and the output of the first light receiving unit 348R1 is When the output is “H”, or when the output of the second light receiving unit 348R2 is the second pulse falling signal FE2 and the output of the first light receiving unit 348R1 is “L”. Re or will occur. Accordingly, the first pulse rising signal RE1 and the first pulse falling signal FE1 of the first pulse signal PS1 and the second pulse rising signal RE2 and the second pulse falling signal FE2 of the second pulse signal PS2 respectively. The first pulse rising edge signal PSFR1, the first pulse falling edge signal PSF2, the second pulse rising edge signal PSR2, and the second pulse falling edge signal PSF2 are sequentially counted by the edge counting unit 358, and biting has occurred. It is stopped at the timing TS.
Thereafter, the rotating body 116 is reversed, and as a result, the rotating disk 132 is reversed, the disc body 102 is reversed, and the moving part 302 approaches the fixed part 298 or is stopped by the buffer 328 thereafter. In this case, as shown in FIG. 18 (B), the moving section 302 approaches the fixed section 298 under the restriction by the front arc-shaped section FC on the front side in the traveling direction of the disc 102, so that the Y direction section 350Y section As described above, when the output of the first light receiving unit 348R1 is the first pulse rising signal RE1 and the output of the second light receiving unit 348R2 is “H”, the output of the first light receiving unit 348R1 is When the first pulse falling signal FE1 and the output of the second light receiving section 348R2 are “L”, the output of the second light receiving section 348R2 is the second pulse rising signal FE2 and the first light receiving section When the output of 348R1 is "L" or when the output of the second light receiving unit 348R2 is the second pulse falling signal FE2 and the output of the first light receiving unit 348R1 is "H" Either it occurs. Therefore, steps S18 to S23 described above are executed, and the count value Cnt in the edge counting unit 358 is sequentially reduced by one for a very short time, and then stopped.
Therefore, when the rotating body 116 is reversed, the maximum count value MC in the maximum count value storage unit 372 is not updated.
Next, when the rotating body 116 is rotated forward again, and when the bite of the disk body 102 is eliminated by the above-described reverse rotation, as shown in FIG. Since the plate body 102 pushes the moving unit 302 and passes between the fixed unit 298, the first pulse rising edge signal PSR1, the first pulse falling edge signal PSF2, and the second pulse rising edge of the first pulse signal PS1. After the signal PSR2 and the second pulse falling edge signal PSF2 are sequentially counted by the edge counting unit 358, at the time when the payout signal DS having the output “L” is output from the passage sensor 290, in step S7 in the main routine processing, The maximum count value MC in the maximum count value storage unit 372 is compared with the reference value PN in the edge reference value storage unit 364. If they are the same, it is determined that the disk 102 is a legitimate disk 102. On the other hand, if the maximum count value MC and the reference value PN are different, it is determined that the disk 102 is improper. An inappropriate disc signal UCS is output.
Therefore, in the present invention, even when the disk body 102 is returned during the movement of the moving unit 302, the count value Cnt in the counting unit 359 (the edge counting unit 358 in this embodiment) is also subtracted. Accordingly, the final maximum count value MC of the pulse signal for discriminating the diameter of the disc 102 is determined when the disc 102 is dispensed, in other words, when the disc 102 is detected by the passage sensor 290. Since the detection is performed based on the maximum count value MC which is the count value Cnt in the count unit 359 (edge count unit 358) at the time of detection, the maximum count value MC during the payout is not affected at all by the disc. There is an effect that the diameter of the body 102 can be detected. The reverse rotation and the forward rotation of the rotating body 116 may be repeated a plurality of times, but the basic operation is performed in the same manner as described above.

This operation will be described in detail with reference to the effect explanatory diagram shown in FIG. Note that in FIG. 19, the direction of movement of the moving unit 302 should normally be the X direction depending on the state of the first detection signal PS1 from the first light receiving unit 348R1 and the state of the second detection signal PS2 from the second light receiving unit 348R2. Or in the Y direction, but for convenience, only the first detection signal PS1 is shown when moved in the X direction, and only the second detection signal PS2 is shown when moved in the Y direction. . The counting in the edge counting unit 358 is performed every time the first pulse rising edge signal PSR1, the first pulse falling edge signal PSF2, the second pulse rising edge signal PSR2, and the second pulse falling edge signal PSF2 are output. However, for convenience, the description will be made assuming that the counting is performed each time the first pulse rising edge signal PSR1 is output.
When the disc 102 moves the moving unit 302 in a direction away from the fixed unit 298 by the normal rotation of the rotating body 116, the combination of the output of the first light receiving unit 348R1 and the output of the second light receiving unit 348R2 is shown in FIG. In the X direction column 350X. Therefore, the first pulse rising edge signal PSR1 based on the first pulse rising signal RE1 in the first detection signal PS1 is sequentially counted as the count value Cnt in the edge counting section 358, and is stopped at the timing TS when biting occurs. Next, the rotating body 116 is reversed and the disc 102 is returned. As a result, the moving unit 302 moves in the direction approaching the fixed unit 298, so that the combination of the output of the first light receiving unit 348R1 and the output of the second light receiving unit 348R2 is the combination in the Y direction column 350Y of FIG. Therefore, every time the first pulse rising edge signal PSR1 is output, the count value Cnt in the edge counting unit 358 is sequentially reduced by one. After the reverse rotation of the rotating body 116 is completed, the rotation is stopped, and the rotating body 116 is rotated forward again. By this forward rotation, the first pulse rising edge signal PSR1 based on the first pulse rising signal RE1 in the first detection signal PS1 is again counted by the edge counting unit 358 as the count value Cnt. This operation is repeated until a straight line connecting the contact point between the disk body 116 and the fixed part 298 and the contact point between the disk body 116 and the moving part 302 reaches the center of the disk body 116. When passing through the center of the body 116, it is ejected by the ejection spring 316. As a result, the moving unit 302 approaches the fixed unit 298, so that the combination in the Y direction column 350Y of FIG. 15 is performed, the count value Cnt in the edge counting unit 358 is sequentially reduced by one, and finally the count value Cnt becomes zero. (Partially omitted in FIG. 19). On the other hand, the passage sensor 290 that has detected the disc 102 ejected by the moving unit 302 immediately outputs the payout signal DS. Therefore, in step S7 in the main routine, the maximum count value MC in the maximum count value storage unit 372 in step S7. The (count value Cnt in the edge counting unit 358) is compared with the reference value PN in the edge reference value storage unit 364, and if they are the same, it is determined that the disc 102 is the regular disc 102; A disc signal UCS is output. As described in the related art 1, when the disc body 116 is returned and the count value Cnt is not subtracted as in the present invention, as shown in FIG. 19, the count value Cnt is larger than the maximum count value MC. Is larger than the conventional first count value MCN1, and when the pulse at the time of the reverse rotation is added, the conventional second count value MCN2 is larger than the conventional first count value MCN1. Therefore, in the present invention, the count value Cnt in the edge counting unit 358, which is the counting unit 359, can be obtained even if the first or second related art is erroneously determined to be the predetermined disc 102. Is subtracted on the way, so that the final discrimination for discriminating the diameter of the disc body 102 is the maximum count value stored in the maximum count value storage unit 372 at the time when the disc body 102 is dispensed. Since the MC is performed based on the count value Cnt in the edge counting unit 358, the diameter of the disc body 102 can be determined without being affected by the movement of the detection target 342 in the reverse direction during the payout. This has the effect.
