Abstract

PROBLEM TO BE SOLVED: To provide a disk body discrimination device capable of correctly discriminating the diameter of a disc body even if the disc body is returned in the course of discrimination.SOLUTION: A moving part is separated from a fixed part by an advancing disc body, and in conjunction with the movement, a cylindrical part in which a detected part and a non-detection part are alternately arranged at equal intervals is rotated. A first detection part and a second detection part are juxtaposed in the rotation direction, and determine whether the moving part is moved by the disc body or the disc body is pushed by the moving part, from the relationship between a first pulse signal and a second pulse signal from these detection parts. Pulse signals from the first detection part is counted when the moving part is moved by the disc body, and conversely, when the disc body is pushed by the moving part, the number of outputs of the pulse signal is sequentially subtracted from the count value of the pulse signal from the first detection part. As such, a count value of the pulse signal at the time of dispensing the disc body is compared with a reference value to determine whether it is an appropriate or inappropriate disc body.SELECTED DRAWING: Figure 1

There is known a disc body discharging apparatus capable of measuring a diameter (see, for example, Patent Document 2).
A third conventional technique is a coin diameter measuring machine that is provided in a device for inserting coins and measures the diameter of the coins, and a reference side surface that is in contact with a part of the circumferential surface of the inserted coins, A diameter measuring piece whose end is pivotally supported and traces the circumferential surface of the measuring coin by the other free end, and the circumferential surface of the measuring coin is directed toward the reference side surface through the free end of the diameter measuring piece.

As a fourth prior art, a disk-shaped hub having a shaft hole that fits the output shaft of the motor at the center, and a cylindrical rim provided on the periphery of the hub, and a light shielding portion in the circumferential direction of the rim, In a rotary encoder comprising a scale in which translucent portions are alternately formed, and a sensor including a light emitting element and a light receiving element fixed to a motor so as to be respectively located inside and outside the rim, the hub and the rim are translucent. The light shielding portion is processed so that light incident in the radial direction is reflected in a direction having an angle with respect to the incident direction, or is printed with the light shielding material. A rotary encoder for a motor characterized by this is known (for example, see Patent Document 4).

JP-A-9-293155 (FIGS. 1 to 5, paragraphs 0004 to 0020) Japanese Patent No. 3709674 (FIGS. 1-5, paragraphs 0004-0026) 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 prior art, the diameter of the disk body is measured based on the number of pulses from when the pulse signal is output from the movement detection means to when the rotating body rotates to a predetermined angular position in the forward rotation of the rotating body. In this kind of disk body diameter measuring apparatus, when the disk body is clogged, the rotating body is reversed and automatic elimination 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, to send out the disk body in a state where the disk body has not yet been released. When the rotating body is rotated in the reverse direction, a pulse for diameter determination is output and counting is continued even though the disk body is returned, or a pulse signal is output because the movement is in the reverse direction. Not. 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 this prior art, it is assumed that the encoder of the rotating body does not output a pulse signal when the rotating body is rotated in reverse. When a pulse signal is output from the movement detection means, the signal processing means counts a high-frequency pulse signal accompanying the rotation of the rotating body from the encoder (displayed in a staircase pattern). When the rotation of the rotating body is stopped after the rotation is stopped in this way, since the pulse signal is not output during the reverse rotation, the count value does not change, and counting of the pulse signal is started when the rotation is performed again in the forward direction. The diameter of the disk body is measured based on the count value E of the pulse signal when the predetermined angular position signal is output from the rotating body. However, if normal measurement is performed without reversal, the pulse signal (displayed with a one-dot chain line in the figure) output while conceiving reversal is also counted. N is 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 diameter. In addition, when a pulse signal is output also at the time of reverse rotation of a rotary body, since a count value becomes larger than the case where it is normal, there exists a problem to discriminate | determine that a disk body is larger diameter than actual.
In the second prior art, in the disk body discharge device that discharges the disk bodies one by one by the rotating means, the movement of the moving unit that is 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 count at the phase conversion point of the pulse signal output from the first and second encoders is counted. The diameter of the disc body is determined based on the edge count value.
In the second prior art, when the rotating means is reversed just after the disk has moved the moving part, in other words, in the state where the disk is not yet released, the first and second encoders Since the phase conversion point of the output pulse signal is generated, the disc body diameter 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 disk body is in the middle of paying out, the count value is smaller than the actual diameter, so that the abnormal disk body is processed as being paid out, that is, despite being normal, There is a problem that is determined to be abnormal.
In the third prior art, the peripheral surface of the coin is pressed against the reference side surface by the measurement piece, and the rotation of the measurement piece is enlarged by the gear and converted into resistance by the potentiometer, and the change pattern of the resistance is referred to as the reference pattern. Since the diameter of the coin is determined by comparison, as described above, when the coin returns in the middle, the resistance pattern is different from the normal case. There are problems that arise.
The fourth prior art is an optical rotary encoder that has a light projecting unit and a light shielding unit, and includes a rotating rim, a pair of light emitting elements 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 prior art to the rotary encoder in the fourth prior art. However, even in this case, in the first conventional technique, the diameter of the disc body is determined based on the count value of the pulses output at the time of reverse rotation. There is a problem that it is determined that the diameter is larger than that. In the second prior art, since the diameter of the disc body is determined based on the count value at the conversion point in the rotational direction of the rim, there is a problem similar to the second prior art.

The passage sensor detects the disc body immediately after passing between the fixed portion and the moving portion, and outputs a payout signal. The discriminating unit compares the count value in the counting unit at the time when the payout signal is received with a reference value to discriminate whether or not the disc body has a predetermined size, and the reset unit determines whether the payout signal is Reset the counting unit. Therefore, even if the rotating body is reversed in the course of discharging the disk body, the suitability of the diameter of the disk body is determined based on the count value of the pulse signal when the disk body is discharged. Even if the disk is returned halfway, there is an advantage that the object of the present invention can be achieved without being influenced by the disk.

The first detection unit outputs a first detection signal each time a plurality of detection units are detected, and the second detection unit generates a predetermined phase difference with respect to the first detection signal each time a plurality of detection units are detected. The second detection signal having the same is output. The movement direction determination unit moves the movement unit when the output order of the first detection signal and the second detection signal from the first detection unit and the second detection unit is the second detection signal after the first detection signal. It is determined that the movement direction is one or the movement direction of the moving unit is the second movement direction opposite to the first movement direction when the second detection signal is followed by the output order of the first detection signal. To do. The counting unit counts the first detection signal and / or the second detection signal in the first movement direction. The subtracting unit counts the first detection signal and / or the second detection signal in the second movement direction, and subtracts it from the count value in the counting unit. The discriminating unit discriminates whether the disc body has a predetermined size based on the count value in the counting unit. Therefore, even when the rotating body is reversed in the course of paying out the disk body and the disk body is returned halfway, the count value is subtracted accordingly, so that no extra counting is performed. Therefore, there exists an advantage which can achieve the objective of this invention, without receiving the influence.

Next, the rotating body hole 124 will be described.
The rotator hole 124 has a function of rotatably installing and accommodating a rotator 116 described later, and is formed by a circular bottom surface 136 formed on the upper surface of the substrate 112 and a circular wall 138 formed on the periphery thereof. And a bottomed circular hole partially opened as a disk body opening 142. Therefore, the disk body opening 142 is formed to be slightly larger than the diameter of the disk body 102 having the largest diameter to be used. A circular sliding plate 144 is installed at the bottom of the rotating body hole 124.

Next, the sliding plate 144 will be described.
The sliding plate 144 is installed at the bottom of the rotating body hole 124, and has a function of sliding the front or back surface of the disc body 102 that has dropped into the through hole 146 of the rotating body 116 on the sliding plate 144. In consideration of durability, a metal flat plate made of stainless steel or the like is formed so as to be closely fitted into the rotating body hole 124. Further, a generally rectangular advance / retreat hole 148 through which a later-described restriction plate 118 can advance and retreat is formed.

Next, the restriction plate hole 126 will be described.
The restricting plate hole 126 has a function of accommodating a restricting plate 118 described later, and is generally L-shaped in plan view in the vicinity of the disc body opening 142 of the circular bottom surface 136 and has a predetermined depth. In the state in which the sliding plate 144 is formed, the hole is surrounded by the entire circumference.

Next, the locking portion 128 will be described.
The locking portion 128 has a function of detachably attaching a base portion of a disk body storage container 114 described later to the substrate 112, and is formed to protrude from the locking hole 140 formed in the disk body storage container 114 and the substrate 112. The disc body storage container 114 is detachably attached to the substrate 112 in cooperation with the locking portion 128 thus made.

Next, the bending portion rotating disk hole 134A will be described.
The bending portion rotating disk hole 134A has a function of rotatably installing a bending section rotating disk 132F, which will be described later. In this embodiment, the bending portion rotating disk hole 134A is a predetermined hole formed near the disk body opening 142 of the rotating body hole 124. 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 body holding container 114 has a function of holding the disc body 102 in a stacked state, and is a vertically-oriented cylindrical body in this embodiment, and its upper end portion 114U is roughly rectangular in plan view, The lower end portion 114B extends in a generally cylindrical shape on the extension of the rotating 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 disk bodies 102 retained in a stacked state in the disk body retaining container 114 one by one and pushing them out in the radial direction of the rotating body 116 at the disk body opening 142. In the embodiment, it is constituted by a circular plate having a predetermined thickness, and is arranged in parallel with the substrate 112 at the bottom of the disc body holding container 114, and the speed reducer 154 is provided by an electric motor 152 arranged on the back side of the substrate 112. And rotated at a predetermined speed. The rotating body 116 is on the same radius centered on the rotation axis and penetrates the rotating body 116 from the upper side to the lower side at intervals of 120 degrees, and from the disk body 102 having the maximum diameter. A through-hole 146 having a slightly larger diameter is also 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 reserved disk body 102 is agitated by the rotation of the rotating body 116. Then, it falls into the through hole 146 while being changed to various postures, and the front surface or the back surface comes into surface contact with the substrate 112. Therefore, a movement path 150 (FIG. 6) of the ring-shaped disk body 102 whose outer periphery is surrounded by the circular wall 138 is formed between the substrate 112 and the lower surface of the rotating body 116. On the back surface of the rotating body 116, a pushing portion 156, a pushing portion 158 at the time of reverse rotation, a protrusion 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 reverse pushing portion 158, the protrusion 162, and the reverse pushing slope 164 move in the moving passage 150. Note that the outer peripheral edge of the rotating body 116 in this embodiment 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 in the lower end portion 114B of the disc body storage container 114, and is disposed in a concave portion (not shown) whose diameter is increased, thereby forming an inner wall of the circular hole. Since it is positioned so as to be concealed, the disc body 102 is prevented from being bitten between the rotating body 116 and the disc body storage container 114. A shaft hole 168 into which an output shaft (not shown) of the speed reducer 154 is fitted is formed at the center, and a drive unit 171 is formed around the shaft hole 168, and in this embodiment, a drive cam 172 is formed. Has been.

Next, the pushing portion 156 will be described. In this embodiment, three pushing portions 156 are formed. Since all the configurations are the same, the same reference numerals are given, and one portion will be described as a representative.
The pushing portion 156 has a function of pushing the disk body 102 in contact with the substrate 112 and sliding it on the substrate 112 (sliding plate 144). In this embodiment, the pushing portion 156 is located below the lower surface 174 of the rotating body 116. The fixed amount protrudes and extends in the radial direction of the rotating body 116, and includes a pushing portion 176 and an extruding portion 178.

Next, the pushing portion 176 will be described.
The pushing portion 176 has a function of pushing the disk body 102 in the region where the disk body 102 is guided by the circular wall 138 and rotating the disk body 102 together with the rotating body 116. In this embodiment, the rotating body It is a portion formed in an inward arc shape that protrudes with a predetermined width toward the lower side of the rotating body 116 along the periphery of the through hole 146 located on the rear side in the rotation direction at the time of normal rotation of the 116. Accordingly, during operation, a slight gap is formed between the pusher lower surface 182 and the circular bottom surface 136 so that they do not rub against each other, and the disc body 102 can move in the radial direction of the rotating body 116. A gap is formed between the lower peripheral edge lower surface 184 and the disk body 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. Thus, when the pushing part 176 exhibits an unbroken narrow surface shape, there is an advantage that the pushing can be smoothly performed when the disk body 102 is pushed. Further, by forming the pushing portion 176 in an inward arc shape, even when the pushing portion 176 pushes the maximum diameter disk body 102L or the minimum diameter disk body 102S, the disk body 102 becomes a circular wall. 138, the first contact point P1 between the disk body 102 and the pushing portion 176 is located outside the center CC of the disk body 102, and the center of the rotating body 116 from the first contact point P1. Side force acts and generates a component force in a direction that cancels the centrifugal force acting on the disk body 102, thereby reducing the pressure contact force on the inner surface of the disk body storage container 114, improving the durability of the apparatus, and There is an effect of preventing the disk body 102 from being damaged.

Next, the extrusion unit 178 will be described.
The push-out portion 178 is arranged such that the disc body 102 pushed by the push-up portion 176 is positioned in the disc body opening 142 and is guided by the restricting plate 118 in the radial direction of the rotating body 116. In this embodiment, the outer surface of the rotating body 116 is positioned on the peripheral side of the rotating body 116 relative to the pressing portion 176. It is configured. That is, the pushing portion 178 has an arc surface shape that is continuous with the pushing portion 176, is opposed to the outer peripheral lower surface 184, and is an outward surface that forms an angle of about 10 degrees with respect to the straight line L1 passing through the center of the rotating body 116. Is formed.

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

Next, the drive unit 171 will be described with reference to FIG.
The drive unit 171 has a function of causing the restricting plate 118 to appear and disappear in the moving passage 150 at a predetermined timing, specifically, a function of moving the restricting 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 used.

Next, the drive cam 172 will be described.
The driving cam 172 cooperates with the restriction plate 118 and has a function of causing the restriction plate 118 to appear in and out of the moving passage 150 at a predetermined timing. In this embodiment, the drive cam 172 is arranged at three positions corresponding to the through holes 146. Since all have the same configuration, one will be described as a representative. The drive cam 172 is formed in an arc-shaped groove 170 having a predetermined radius with the rotation axis RS of the rotating body 116 as the center, is formed at one end of the arc-shaped groove 170, and the rotating body 116 is rotated forward (the disc body 102). Is formed between the descending slope 172D, which is a downward slope, the upward slope 172U formed at the other end, and the downward slope 172D and the upward slope 172U, and the downward slope 172D. The deepest part of the climbing slope 172U and the deepest part of the climbing slope 172U are connected to each other at the same depth by a maintaining part 172H. In other words, the drive cam 172 is formed in a groove shape with a circumferential cross section 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 body 102 pushed by the pushing portion 176 and the pushing portion 178 by the rotation of the rotating body 116 in the radial direction of the rotating body 116. In the present embodiment, A restriction body 186 disposed in the restriction plate hole 126 is formed. As shown in FIGS. 5 and 6, the restricting body 186 is formed in an inverted L shape, and extends in the circumferential direction of the rotating body 116 and extends from the main body section 188 to the rotation center side of the rotating body 116. And a driven part 192 that includes
One end portion 188E of the main body portion 188 is formed with a support portion 194 formed in a crotch shape, a restriction plate 118 is formed at the other end portion 188O, and a guide portion 196 is provided at the intermediate portion 188M.

Next, the support part 194 will be described.
The support portion 194 has a function of receiving a force acting on the restriction plate 118 and holding the main body portion 188 so that the posture thereof 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 thus formed is inserted into the crotch portion.

Next, the guide part 196 will be described.
The guide portion 196 has a function of restricting the movement of the restricting plate 118 to a predetermined range. In the present embodiment, the guide portion 196 is fixed downward to the long hole 202 formed in the intermediate portion 188M and the sliding plate 144, The distal end portion is constituted by a fixing pin 203 inserted into the long 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 limited by the fixing pin 203.

  The restricting plate 118 has a function of preventing the disk body 102 that is pushed by the pushing portion 176 from being rotated and guiding it in the radial direction of the rotating body 116. In the present embodiment, the restricting plate 186 constitutes the restricting body 186. The other end portion 188O of the main body portion 188 is formed so as to protrude upward at a right angle to the main body portion 188. In the present embodiment, the restriction plate 118 is divided into an inner restriction plate 118 </ b> I and an outer restriction plate 118 </ b> O close to the rotation center of the rotating body 116 by a receiving groove 206 that receives an outer protrusion 162 </ b> O formed later. . An end surface of the regulation plate 118 on the side opposite to the support portion 194 is a regulation surface 208. Therefore, the regulation surface 208 is also divided into an inner regulation surface 208I and an outer regulation 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, and normally the lower surface of the main body portion 188 of the restricting body 186 and the bottom surface of the restricting plate hole 126. A spring 214 serving as an urging portion 204 disposed between the two is protruded on the sliding plate 144 and is urged so as to be positioned at a regulation position CP (FIG. 8) located in the moving passage 150. When the restricting body 186 protrudes on the sliding plate 144, the upper end of the restricting body 186 protrudes into the moving surface of the moving passage 150, and hence the pushing portion 176, but the pushing portion 176 is moved to the restricting body 186 by the driven cam 212. In accordance with the movement so as not to collide, it is moved to the retracted position PP (FIG. 6B) that has retreated from the surface of the sliding plate 144. As shown in FIG. 8, when the sliding plate 144 is positioned below the through hole 146, the total length thereof, that is, the total length of the inner regulating plate 118 </ b> I, the receiving groove 206 and the outer regulating plate 118 </ b> O is larger than the diameter of the through hole 146. Is slightly shorter. “Slightly short” means that it is 70% or more with respect to the diameter of the through hole 146. When the length of the regulation surface 208 is short, for example, when targeting 10 yen, 50 yen, 100 yen and 500 yen coins in Japanese yen, when sending out 50 yen coins which are the disk bodies 102 with the smallest diameter, This is because 50-yen coins are not smoothly guided and smooth delivery may not be possible.

Next, the regulation 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 the present embodiment, the restriction surface 208 is made of metal in order to prevent wear due to sliding with the disk body 102, or The resin is covered with a metal plate.

  In this embodiment, the regulating plate 118 is further formed with a reverse driven portion 210. Since the driven portion 210 at the time of reverse rotation is retracted from the moving path of the pushing portion 156 when the rotating body 116 rotates in the reverse direction, it has a function of being pushed down by the pressing slope 164 at the time of reverse rotation of the rotating body 116. It is formed on an inclined surface formed on the opposite side of the regulating surface 208 of the regulating plate 118 so as to rise upward toward the regulating surface 208 side. Specifically, an inner reverse driven portion 210I is formed opposite to the inner restricting surface 208I, and an outer reverse driven portion 210O is formed opposite to the outer restricting surface 208O. Furthermore, when the reverse rotation driven portion 210 in this embodiment is a climbing slope, it is also the climbing slope 220 of the disc body 102. When the rotating body 116 is reversed, the boarding slope 220 can be moved over by being guided by the boarding slope 220 with the disk body 102 pushed by the pushing section 158 at the time of reverse rotation. However, the inner reverse driven portion 210I and the outer reverse driven portion 210O only need to exhibit their functions, and 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, in the process in which the pushing portion 156 moves in the moving passage 150, the restricting body 186 In the present embodiment, the driven cam 212 is pushed by the drive cam 172 to move the restricting body 186 below the sliding plate 144, and in this embodiment, the restricting body 186 is prevented from colliding with the pushing portion 156. The body 186 is configured to move up and down with respect to the sliding 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. Therefore, since the driven cam 212 presents a stationary body with respect to the rotating body 116, when the rotating body 116 rotates, the ascending slope 172U comes into contact with the descending portion 212D immediately before the pushing portion 176 reaches the regulating surface 208. Therefore, the restricting body 186 is moved downward with respect to the sliding plate 144, so that the restricting surface 208 is retracted into the advance / retreat hole 148 and is positioned at the retracted position PP. The leading part 156 does not collide with the regulation surface 208. This state continues while the rotating body 116 further rotates and the retreat continuation unit 212H faces the lower surface of the pushing unit 176. However, when the climbing portion 212U comes into contact with the descending slope 172D, the restricting body 186 is moved upward with respect to the sliding plate 144 by the elastic force of the spring 214, and the restricting surface 208 is moved to the moving passage 150 above the sliding plate 144. And is moved to the restriction position CP of the disc body 102, so that the full length of the restriction plate 118 is located in the movement passage 150. This state is performed before the restricting plate 118 is opposed to the through hole 146, and the retraction continuation portion 212H is opposed to the maintenance portion 172H, and thus does not interfere with the pushing portion 156 that moves next. Continued in

Next, the reverse pushing portion 158 will be described.
The reverse rotation pushing portion 158 has a function of pushing the disc body 102 located in the through hole 146 when the rotating body 116 is reversed, and rotating the rotating body 116 together with the reverse rotation of the rotating body 116. In this embodiment, it is formed of 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 pushing portion 158I is constituted by the inner protrusion 162I, and the outer reverse pushing portion 158O is constituted by the respective rear end surfaces of the outer protrusion 162O.
Therefore, the disc body 102 that has fallen into the through hole 146 is supported by the substrate 112 (sliding plate 144) on the lower surface, the pushing portion 176 on the rear, the pushing portion 158 at the time of reverse rotation, and the circular wall on the outer periphery. The rotary body 116 is rotated by the rotation of the rotating body 116 while being held by the holding portion 160 that is surrounded by 138 and is located immediately below the through hole 146.

Next, the protrusion 162 will be described mainly with reference to FIGS.
The protrusion 162 has a function of forming a reverse rotation pushing portion 158 that pushes the disc body 102 when the rotating body 116 is rotated in the reverse direction, and has a function of reinforcing the rotating body 116 as a secondary. In this 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, both having the same configuration. The first inner protrusion 162I and the outer protrusion 162O will be described as a representative.

First, the inner protrusion 162I will be described.
The inner ridge 162I is an arc-shaped ridge having a predetermined width centered on the inner virtual circle CRI having a radius RI and centered on the rotation axis RS of the rotating body 116, and the pushing portion 176 is predetermined in the forward rotation direction. The inner recess 218I and the outer recess 218O are formed to form a narrow arc shape, and the rear end of the forward rotation is formed to the vicinity of the through hole 146, and the rear end face is It is a pushing part 158I at the time of inner side reverse rotation. The inner protrusion 162I is disposed in the receiving groove 206. Therefore, when the inner protrusion 162I is in a positional relationship facing the receiving groove 206, the restricting body 186, and thus the restricting surface 208, can be located at the restricting position CP in the movement path 150.

Next, the outer protrusion 162O will be described.
The outer ridge 162O is an arc-shaped ridge having a predetermined width centered on the outer virtual circle CRO having a radius RO and centering on the rotation axis RS of the rotating body 116, and the pushing portion 176 is predetermined in the forward rotation direction. Is formed outside the outer recess 218O in the form of a narrow arc to the vicinity of the through hole 146, and the rear end surface thereof is the outer reverse pushing portion 158O. The outer reverse rotation pushing portion 158O and the boundary portion 180 constitute an outlet opening 218, and the distance between them is formed to be slightly larger than the maximum diameter disc body 102L (FIG. 4). The outer protrusion 162O is opposed to the outside of the outer regulating surface 208O, and the pushing portion 156 is not formed at this portion.

Next, the pressed slope 164 during reverse rotation will be described.
The pressing down slope 164 at the time of reverse rotation has a function of retracting the restricting body 186 and therefore the restricting surface 208 to the retracted position PP in the advance / retreat hole 148 of the sliding plate 144 when the rotating body 116 is reversely rotated. In FIG. 2, the inner concave portion 218I and the outer concave portion 218O are formed by inner reverse pressing slopes 164I and outer reverse pressing slopes 164O formed on the end surfaces on the pushing portion 156 side. In other words, the inner inclined reverse slope 164I and the outer reverse depressed slope 164O are inclined surfaces that incline in a straight line 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 restricting plate 118, the restricting body 186 is not moved by the drive cam 172, so that the inclined surface 164 </ b> I at the time of inner reverse rotation is positioned in the inner recess 218 </ b> I It is located in the outer recess 218O. In this state, when the rotating body 116 is reversed, the slope 164I that is pressed when reversing the inner side comes into contact with the inner slope on the back surface of the regulating plate 118, and the slope 164O that is pushed when reversing the outer side comes into contact with the outer slope. The regulating body 186 is pushed down against the force. As a result, the restricting plate 118 is moved to the retracted 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 disk body delivery device 100 of the embodiment will be described.
First, a predetermined disk body 102, for example, one type of disk body 102 or a plurality of types of disk bodies 102 are held in a stacked state in the disk body storage container 114.
The electric motor 152 is rotated by the payout command of the disk body 102, and the rotating body 116 rotates in the forward direction at the bottom of the disk body storage container 114 via the speed reducer 154 and in the counterclockwise direction in FIGS. Is done. As a result, the disc body 102 placed on the rotating body 116 is agitated, falls into the through hole 146 in the process of changing the posture in various ways, and is brought into surface contact with the sliding plate 144. In other words, the disc body 102 is located in the movement path 150. Accordingly, the disc body 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 pusher 176 is pushed by the pusher 176, the pusher 176 is formed in an inwardly arcuate shape. Therefore, the first contact P1 between the disc body 102 and the pusher 176 is the disc with the smallest diameter. 102S, which is on the outer peripheral side of the center CC (FIG. 8). As a result, a vector directed to 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 from the first contact point P1, so that the sliding pressure on the circular wall 138 can be reduced. There is an effect that it is possible to suppress damage to the peripheral surface of the disk body 102 and wear of the circular wall 138.
When the disc body 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 contacts P3 and the reaction force F2 from the fourth contact P4 between the inner regulation surface 208I and the disk body 102 is directed to the disk body opening 142, the disk body 102 This relationship does not change even when the disk body is pushed toward the disk body opening 142 and moves to the outer regulating surface 208O. Finally, the outward pushing portion 178 causes the disk body opening 142 to pass through the radial direction of the rotating body 116. It is pushed out to the disc body guide passage 232 located at the position. Even 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 restricting plate 118, the downward slope 172D of the drive cam 172 After the climbing portion 212U of the driven cam 212 is pushed down, the position thereof is continued by the drive cam retreat continuation portion 172C. Therefore, the restriction plate 118 is moved downward with respect to the sliding plate 144, and the restriction surface 208 is moved to the retraction position PP. Since the retracted position PP is continued while the drive cam retracting portion 172C and the maintaining portion 172H are opposed to each other, the restricting plate 118 does not collide with the pushing portion 156. Thereafter, when the downward slope 172D faces the retreat continuation part 212H from the ascending part 212U, the restriction plate 118 is pushed up by the urging force of the spring 214 and moved to the restriction position CP. continue. In other words, immediately after the pushing portion 156 passes through the relative position with the restricting plate 118, the downward slope 172D faces the retreat continuation portion 212H, and the restricting plate 118 is moved to the restricting position CP. At this time, since the inner protrusion 162I advances to the receiving groove 206, the restricting plate 118 is moved to the restricting position CP before facing the through hole 146, and preparation for the next disc body 102 is prepared. For example, when the rotation of the rotating body 116 is stopped due to the disk body 102, the rotating body 116 rotates in the reverse direction, in the present embodiment, clockwise. When the rotating body 116 is rotated in the reverse direction, the pressing slope 164 at the time of reverse rotation contacts the driven portion 210 at the time of reverse rotation. Specifically, the inner inclined reverse slope 164I contacts the inner reverse driven portion 210I, and the outer reverse pressed slope 164O contacts the outer reverse driven portion 210O, and pushes the inner reverse driven portion 210I and the outer reverse driven portion 210O down. As a result, the restricting plate 118, and therefore the restricting surface 208 is moved to the retracted position PP, so that the rotating body 116 can be reversed without interfering with the restricting plate 118.

Next, the operation of the rotating body 116 during reverse rotation will be described with reference to FIG.
When the rotating body 116 rotates in the reverse direction, that is, rotates in the clockwise direction, the disk body 102 fed to the disk body guide passage 232 rotates in the counterclockwise direction of the rotating disk 132 and finally the curved portion rotating disk 132C. Is forcibly returned to the disk body opening 142. In this case, as shown in FIG. 17A, the restriction plate 118 is located below the through hole 146, and thus is located at the restriction position CP, in other words, protrudes into the movement passage 150. When the disc body 102 in the disc body storage container 114 is located in the through hole 146, the disc body 102 is lifted by the movement of the regulation plate 118 to the regulation position CP, and is placed on the sliding plate 144 and the regulation plate 118. A gap larger than the thickness of the disc body 102 having the maximum thickness is formed between the disc body 102 and the disc body 102. In this state, the disk body 102 returning from the disk body guide passage 232 is supported by the tip 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 pushing portion 176 is smaller than the minimum diameter disk body 102S, even the minimum diameter disk body 102S is in surface contact. It is not possible. Also. The minimum-diameter disk body 102S pushed up by the restriction plate 118 has a center of gravity located on the restriction plate 118 or at a position farther from the pusher 176 than the center of gravity of the minimum-diameter disk body 102S. A space is formed between the sliding plate 144 and the lower sliding plate 144. Therefore, even when the minimum-diameter disk body 102S is positioned in the through hole 146, the end of the minimum-diameter disk body 102S returned from the disk body guide passage 232 can advance into the space.
As shown in FIG. 17B, when the rotating body 116 is further rotated in the clockwise direction, the distance between the restricting surface 208 and the pushing portion 176 increases. Since the minimum diameter disc body 102S returned from 232 is supported by the tip of the outer regulation plate 118O and the pushing portion 178, the distance between the regulation surface 208 and the pushing portion 176 is smaller than the diameter of the minimum diameter disc body 102S. The minimum diameter disc body 102S placed on the outer regulating plate 118O cannot come into 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 body 102S returned from 232 is supported by the outer regulation plate 118O, the inner regulation plate 118I, and the boundary portion 180, the distance between the regulation surface 208 and the pushing portion 176 is larger than the diameter of the minimum diameter disc body 102S. Therefore, the minimum-diameter disk 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 restricting surface 208 and the pushing portion 176 increases. In this state, the minimum-diameter disk body 102S is inwardly restricted. Since it is supported by the plate 118I and the pushing portion 176, the minimum diameter disk body 102S returned from the disk body guide passage 232 is positioned in the through hole 146, but the returned minimum diameter disk body 102S is Since it is already located in the through hole 146, the minimum diameter disk 102 </ b> S placed on the outer regulating plate 118 </ b> O cannot come into surface contact with the sliding plate 144. Therefore, the two minimum-diameter disk bodies 102S are not positioned side by side on the sliding plate 144 below the through hole 146.

Next, referring to FIG. 1, a disk body delivery / conveying apparatus 108 using the disk body delivery apparatus 100 according to the present invention will be described.

The disc body discriminating device 240 is disposed on the disc. Specifically, the disc body guide passage 232 includes a back guide body 254 and a top plate 256, and the top plate 256 is detachably attached to the back guide body 254 with screws or the like. Further, as shown in FIG. 2B, the substrate 112 is inclined by about 45 degrees, and the disc body guide passage 232 is finally suspended, so that the vicinity of the entrance 228 of the disc body guide passage 232 is. Is configured as a curved portion 260 that is curved with respect to the front and back surfaces of the disc 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 FIG. 3A). In other words, the guide surface located on the right side in FIG. 3B, the first arcuate guide surface 258 and the first chevron guide surface 262 are alternately arranged. In other words, the first chevron guide surface 262 is a laterally chevron-shaped projection formed by an upstream first slope 262I inclined to the left and rising upstream, and a downstream first slope 262O that is located downstream and slopes upward to the right. Parts.

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. In the present embodiment, the second guide surface 246 is formed to be opposed to the first chevron guide surface 262 formed on the top plate 256. The second arcuate guide surface 264 and the second chevron guide surface 266 formed to face the first arcuate guide surface 258. The second arcuate guide surface 264 is curved laterally upward, and then extends substantially vertically upward, and then forms a laterally concave portion that curves upward.
The second chevron guide surface 266 has a right side chevron protrusion formed by an upstream second slope 266I that slopes upward to the right and a downstream second slope 266O that is located downstream and slopes forward to the left. Parts.
Therefore, the first guide surface 244 and the second guide surface 246 define a passage that has a predetermined width and regularly swells right and left in the 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 disk body guide passage 232, in other words, a function of guiding the surface of the disk body 102, specifically, the front surface or the back surface of the disk body 102. In this embodiment, it is constituted by the surface of the elongated flat plate 250 having a predetermined thickness. As shown in FIG. 2B, the third guide surface 248 is formed to be arcuately concave with a predetermined radius with respect to the front and back surfaces of the disc body 102 at a portion corresponding to the curved portion 260. .

Next, the fourth guide surface 252 will be described.
The fourth guide surface 252 has a function of determining the front surface of the disk body guide passage 232, in other words, a function of guiding the surface of the disk body 102, specifically, the front surface or the back surface of the disk body 102. In this embodiment, the top plate 256 is formed of an elongated flat plate made of a transparent resin. A portion corresponding to the curved portion 260 of the fourth guide surface 252 is formed to be convex with respect to the front and back surfaces of the disc body 102 at a radius smaller than that of the third guide surface 248.
Accordingly, the first guide surface 244, the second guide surface 246, and the fourth guide surface 252 of the disc body guide passage 232 are formed on the top plate 256, and the first guide surface 244 and the second guide surface 246 are formed. The third guide surface 248 and the fourth guide surface are formed so as to be 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. The distance from 252 is slightly larger than the thickness of the thickest disc body 102 and less than twice the thickness of the thinnest disc body 102. In other words, the disk body guide passage 232 is configured so that the two disk bodies 102 do not overlap in the diameter direction or the thickness direction as long as the diameter and thickness range of the disk body 102 assumed to be used. It 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 disc body 102 having the maximum thickness can pass through. This is because the disc body 102 is in 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 increased. This is because it apparently increases.

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 this embodiment, the lower end is fixed to the frame 122 and extends upward. It is comprised by the plate-shaped body made from sheet metal.

That is, these gear trains 274 have a function of rotating a turntable 132 described later at a predetermined speed.

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 hence the speed reducer 154 to the rotating disk 132 and rotating them. In this embodiment, the rotating gear is rotated integrally with the rotating body 116. 274R, a curved portion gear 274C that meshes with the rotating body gear 274R, a first rotating disc gear 274F that meshes with the curved portion gear 274C, and an integral rotating disc that is the same as the rotating disc gear 274S and is integrally formed with the first rotating disc gear 274F It is constituted by a gear 274FS and a rotating disk gear 274S that meshes with the integrated rotating 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 portion gear 274C is 1 to 1.5, the rotation ratio between the bending portion gear 274C and the first rotating disc gear 274F, and the rotation ratio between the first rotating disc gear 274F and the rotating disc gear 274S. The ratio is 1: 1. Accordingly, since the bending portion rotating disk 132C rotates 1.5 times while the rotating body 116 makes one rotation, the through hole 146 and the disk 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 at the same phase in a one-to-one speed ratio relationship. In other words, the disc body 102 pushed out by the pushing portion 178 by the rotation of the rotating body 116 proceeds to the disc body guide passage 232, and the curved portion first disc body pusher 234C or the curved portion second disc body. It can be moved to the disc body guide passage 232 by the push body 236C, and in the disc body guide passage 232, the bending portion first disc body pushing body 234C, the bending portion second disc body pushing body 236C, and The first rotary disk first disk body pusher 234F, the first rotary disk second disk body pusher 236F, the first disk body pusher 234, and the second disk body pusher 236 are sequentially and positively conveyed.

In this embodiment, the turntable 132C, The first turntable 132F and the reference turntable 132S are configured. However, since the structures described below are common to all the turntables, the reference turntable 132S will be described as a representative.

  The reference rotation disk 132S is used in the planar disk body guide passage 232, and circular reference rotation disks 132S having a first disk body pusher 234 and a second disk body pusher 236 are arranged at predetermined intervals. It is installed. The reference rotating disk 132S is provided so as to be rotatable about an axis perpendicular to the base body 268, and hence the disk body guide passage 232, and the surface 273 thereof is substantially flush with the third guide surface 248. It is configured as follows. The reference rotating disk 132S of this embodiment is provided so as to be rotatable about an axis near the top of the first chevron guide surface 262 or the second chevron guide surface 266, and the first disc body pusher 234 and the second disc body. The pusher 236 is arranged point-symmetrically with respect to the axis. In addition, when manufacturing the 1st disc body pushing body 234 and the 2nd disc body pushing body 236 with resin, in order to prevent abrasion, it is preferable to cover the part which pushes the disc body 102 with a sheet metal. . Further, the distal ends of the first disk body pusher 234 and the second disk body pusher 236 are inserted into an annular groove 276 formed in the top plate 256 so that the disk body 102 is the first disk body pusher 234. Alternatively, the second disc body pusher 236 is configured not to drop off. 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 rotational speed 1.5 times the rotational speed of the rotating body 116. All the turntables 132 are rotated at the same speed, the adjacent turntables 132 are rotated in opposite directions, and the first disc body pusher 234 and the second disc body pusher 236 are predetermined. Are rotated in the phase relationship. In the above description, the basic functions and structures are the same in all the turntables 132. However, the bending portion turntable 132C facing the bending portion 260 and the first turntable 132F adjacent thereto are different from the reference turntable 132S. Since there is a difference in the detailed structure, the difference will be described below.

First, the bending portion rotating disk 132C will be described.
The bending portion rotating disk 132C has a function of sending 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 disk body pusher 234C and the curved second disk body pusher 236C are longer than the first disk body pusher 234 and the second disk body pusher 236 in the reference rotating disk 132S. These tips are pivotable in a curved portion annular groove 276C formed in the curved portion top plate 256C. In addition, the circumferential lengths of the bending portion first disk body pushing body 234C and the bending portion second disk body pushing body 236C in the bending portion rotating disk 132C are the rotation direction front end 278C and the rotation direction rear end 282C. The interval, and therefore, the disc body passage 284C is formed to be slightly larger than the interval through which the maximum diameter disc body 102 can pass, and the bending portion first disc body pushing body 234C and the bending portion second disc body pushing body 236C. The circumferential length of the curved portion rotating disk 132C has a continuous arc shape except for the disk body passage 284C. When the bending portion first disc body pushing body 234C and the bending portion second disc body pushing body 236C are integrated with the bending portion rotating disk 132C in an arc shape, there is an advantage that these 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. A curved portion second arcuate guide surface 264 </ b> C that is opposite to the curved portion first chevron guide surface 262 </ b> C is also formed on the substrate 112. 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.

This is because the disc body guide passage 232 is curved in the vicinity of the bending portion rotating disk 132C (the hatched portion in FIG. 4A). A chamfered portion 288 is formed on the outer sides of the first rotating plate first disc body pusher 234F and the first rotary disc second disc body pusher 236F of the first turntable 132F. This is to avoid interference between the bending portion first disk body pushing body 234C and the bending portion second disk body pushing body 236C in the bending portion rotating disk 132C.

  In the present embodiment, as shown in FIG. 3, the outlet first chevron guide surface 262E facing the final turntable 132E closest to the outlet 106 is the first upstream of the other first chevron guide surfaces 262.

In a state where the swing lever 312 is locked to the buffer body 328, the roller 314 is positioned at the end of the arc-shaped elongated hole 334 as shown by a chain line in FIG. 3B and close to the guide pin 306 serving as the fixing portion 298. It is stopped at the standby position SP. At this standby position SP, the rollers 314 are arranged in a positional relationship where they are moved by a predetermined amount when the minimum-diameter disk body 102S passes. In other words, the roller 314 is moved in a direction away from the fixed portion 298 by the disk body 102 that is supposed to be used, and after the disk body 102 has passed, the roller 314 is returned by the ejection spring 316 and the buffer body. 328 holds the standby position SP. Therefore, the arc-shaped long hole 334 is formed in an arc shape centering on the rotation axis of the final turntable 132E. The roller 314 may be a shaft 322 that is a rod that does not rotate. However, since the roller 314 has a small frictional resistance, it has excellent advantages in terms of durability and disc ejection.

Next, the ejection spring 316 will be described.
The ejection spring 316 has a function of applying a force to press the roller 314 against the peripheral surface of the disc body 102 in the outlet guide passage 232E. In this embodiment, the middle part is wound around the fixed shaft 308. The elastic linear body 324 is configured such that one end 316L of the elastic linear body 324 is hooked on a convex piece 326 cut and raised from a rectangular opening 325 in the detection unit cover frame 296C, and the other end 316R is a swing lever 312. The roller 314 is always elastically urged toward the fixed portion 298 side. Therefore, the disc body 102 is finally ejected by the resilience of the ejection spring 316, and thus by the roller 314. However, the lower surface of the swing lever 312 is locked to the buffer body 328 fixed to the protrusion protruding laterally from the detection unit base frame 296 </ b> B and cannot approach more than a predetermined distance. The presence or absence of the central hole is detected by the central hole detection sensor 330 immediately before the disk body 102 is ejected.

Next, the center hole detection sensor 330 will be described.
The center hole detection sensor 330 has a function of detecting a disk body 102 having a center hole, for example, a 5-yen coin, a 50-yen coin, or a specially manufactured disk body 102. In the outlet guide passage 232E, the disc body 102 is sandwiched between the fixed portion 298 and the moving portion 302, and the arc portion on the rear side in the traveling direction of the disc body 102 starts to be pushed out by the moving portion 302. When the light from the light projecting unit is received by the light receiving unit, it is determined that the disc body 102 has the central hole, but the center hole detecting sensor 330 is configured by another method. You can also. By detecting the presence or absence of the central hole in a state in which the disc body 102 starts to be pushed out, there is an advantage that an abnormality of the dispensed disc body 102 can be detected.

Next, the pulse signal generator 304 will be described mainly with reference to FIG.
The pulse signal generation unit 304 has a function of outputting a pulse signal PS in conjunction with the movement of the movement unit 302, and in the present embodiment, is configured by at least an oscillating body 336 and a sensor 338. However, the rocking body 336 is not limited to the rocking body 336, and the rocking body 336 can be changed to a linear reciprocating body.

Next, the rocking body 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 the detection unit 292 so that a pulse signal can be output based on detection of the sensor 338 for each predetermined oscillating amount. In the present embodiment, it is constituted by a pan-shaped detected body 342 formed in a bottomed cylindrical shape by a light transmissive transparent resin. The detected body 342 is rotatable about the fixed shaft 308 and is configured to swing integrally with the swing lever 312.

Next, the detected object 342 will be described.
The detected body 342 has a cylindrical cylindrical portion 342 </ b> P connected to the outer peripheral edge of a disk-shaped bottom portion 342 </ b> B, and the center of the bottom portion 342 </ b> B is disposed on the axis SL of the fixed shaft 308. The cylindrical portion 342P has a trapezoidal cross section parallel to the axis SL, as shown in FIGS. 14B, 14C, 14D, and 14E. A certain non-detecting portion 344 and a flat plate-like detected portion 346 disposed between the upward slope and the downward slope are formed at a predetermined interval. The non-detecting 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 part 346 may have a structure in which the projection light from the light projecting part 348P reaches the light receiving part 348R, even if it is not flat. In the present embodiment, since the sensor 338 is an optical sensor, the non-detection unit 344 is formed on a slope having an angle of 45 degrees with respect to the projection light, and the projection light from the light projecting unit 348P is reflected by the slope. Since it is deflected from the light receiving portion, the function of the non-detecting portion 344 is exhibited, and since the detected portion 346 has a flat plate shape, light can be transmitted linearly and reach the light receiving portion 348R. Demonstrate the function. Specifically, as shown in FIG. 14B, the first detected portion 346L, which is the lower flat plate portion, the first non-detected portion 344L, the second detected portion 346H, which is the higher flat plate portion, and The second non-detecting portions 344R are repeatedly arranged at equal pitches, in other words, at equal intervals, and their circumferential lengths are set to be the same. Further, in the relationship with the sensor 338 described later, the projection light of the pair of sensors 338 is simultaneously the same first detected unit 346L, first non-detected unit 344L, second detected unit 346H, or second non-detected unit. Therefore, when the optical sensor is used as the sensor 338, the detection target 342 having the same function can be used. For example, as the non-detection unit 344, a tape that does not transmit light may be attached, colored, or formed on the anterior surface. The number of pairs of the detected part 346 and the non-detecting part 344 is preferably provided as much as possible in order to determine the accuracy in detecting the diameter of the disc body 102. However, due to physical limitations in manufacturing, 180 pairs or more are necessary at least 360 degrees, but 300 pairs or more are preferable.

Next, the sensor 338 will be described.
The sensor 338 has a function of outputting a pulse signal PS in cooperation with the non-detection unit 344 and the detection unit 346 of the detection target 342. In the present embodiment, the sensor 338 includes the optical sensor 348 and the cylindrical unit 342P. The light projecting portion 348P disposed inside the light receiving portion 348P and the light receiving portion 348R disposed outside the cylindrical portion 342P and disposed so as to receive light projected from the light projecting portion 348P. The light projecting unit 348P and the light receiving unit 348R are arranged at a predetermined distance in the circumferential direction of the cylindrical unit 342P, and the first light projecting PL1 from the first light projecting unit 348P1 outputs the first detection signal PS1. The second light projecting PL2 from the second light projecting unit 348P2 and the second light projecting unit 348P2 are configured to enter the second light receiving unit 348R2 that outputs the second detection signal PS2. Therefore, the first light projecting unit 348P1 and the first light receiving unit 348R1 constitute a first detecting unit 3491, and the second light projecting unit 348P2 and the second light receiving unit 348R2 constitute a second detecting unit 3492. The first projection PL1 and the second projection PL2 are parallel lights. In addition, the predetermined distance means that the first detection unit 346L, the first non-detection unit 344L, the second detection unit 346H, or the second non-detection unit 344R is not projected simultaneously and the first detection is performed. The signal PS1 and the second detection signal PS2 are distances in which the rising edge and the falling edge are shifted and the output state shown in FIG. The meaning of this predetermined distance is detected by the disc body determination unit 294 based on outputs from the first detection unit 3491 and the second detection unit 3492, in other words, from the first light receiving unit 348R1 and the second light receiving unit 348R2. By exhibiting the function of determining whether the rotation direction of the body 342 is counterclockwise or clockwise in FIG. 14A and exhibiting the function of representing the rotation angle of the cylindrical portion 342P. is there. In the present embodiment, when the first projection PL1 from the first projection unit 348P1 passes through the detected unit 346 (the first detected unit 346L or the second detected unit 346H), the first projection PL1 is Light is received by the first light receiving unit 348R1, and the second light projection PL2 from the second light projecting unit 348P2 is received by the second light receiving unit 348R2 by the non-detecting unit 344 (the first non-detecting unit 344L or the second non-detecting unit 344R). Not.

Next, the PS2 rising edge detection unit 356 will be described.
The PS2 rising edge detection unit 356 has a function of detecting the rising edge of the second pulse signal PS2, and outputs the second pulse rising edge signal PSR2 when the rising edge is detected.

Next, the PS2 falling edge detection unit 357 will be described.
The PS2 falling edge detection unit 357 has a function of detecting the falling edge of the second pulse signal PS2, and outputs the second pulse falling edge signal PSF2 when the falling edge is detected.

Next, the counting unit 359 will be described.
The counting unit 359 counts the first pulse falling edge signal PSF1, the first pulse falling edge signal PSF1, the second pulse rising edge signal PSR2, and the second pulse falling edge signal PSF2 in the first movement direction X. The count value Cnt has a function of outputting it as a digital value. In this embodiment, the edge counting unit 358 has the function.

Next, the movement direction determination unit 360 will be described.
The movement direction determination unit 360 has a function of determining the movement direction of the detection target 342, in other words, the rotation direction of the cylindrical portion 342P. Specifically, the first detection unit 3491 (first light receiving unit 348R1). The rotation direction of the cylindrical portion 342P is determined based on the first detection signal PS1 from the second detection signal PS2 and the second detection signal PS2 from the second detection portion 3492 (second light receiving portion 348R2).

A method of discriminating the rotation direction by the first detection signal PS1 and the second detection signal PS2 in the movement direction discrimination unit 360 will be described with reference to FIGS. In the following description, the output “L” indicates a state in which the output level of the first detection signal PS1 or the second detection signal PS2 that is a pulse signal is relatively low, and the output is “H”. This represents a state where the output level of the first detection signal PS1 or the second detection signal PS2 which is a pulse signal is relatively high. In FIG. 14, the detected object 342, which is the first half when the disc body 102 passes through the detection unit 292, is rotated counterclockwise by the front arcuate portion FC on the front side in the traveling direction of the disc body 102 (FIG. 14). 15 (A)), 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 is The relative position shifts from the second non-detecting part 344R to the first detected part 346L or from the first non-detecting part 344L to the second detected part 346H, and the second light receiving part 348R2 is changed from the first detected part 346L to the first. The relative position moves from the non-detecting part 344L or the second detected part 346H to the second non-detecting part 344R. Thereby, as shown in the X direction column 350X in FIG. 15C, the first non-detecting unit 344L shifts to the second detected unit 346H or the second non-detecting unit 344R to the first detected unit 346L. At this time, the first light receiving unit 348R1 outputs the first pulse PS1 rising signal RE1 (simply indicated by an upward arrow in FIG. 15C), and the output of the second light receiving unit 348R2 is L, When shifting from the first detected portion 346L to the first non-detected portion 344L or from the second detected portion 346H to the second non-detected portion 344R, the first light receiving portion 348R1 outputs the first pulse falling signal FE1, In addition, the output of the second light receiving unit 348R2 is H, and the second light receiving unit 348R2 moves from the first non-detecting unit 344L to the second detected unit 346H or from the second non-detecting unit 344R. When moving 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 second detected portion 346H When the second non-detecting unit 344R or the first detected unit 346L shifts to the first non-detecting unit 344L, the second light receiving unit 348R2 outputs the second pulse falling signal FE2 and the first light receiving unit 348R1. The output of is L. On the other hand, the reverse second movement when the pusher 302 pushes the rear arcuate part BC on the rear side in the traveling direction of the disc body 102, which is the latter half when the disc body 102 passes the detection unit 292. When moved to the right in the direction Y, the first light receiving unit 348R1 is in a relative position from the first non-detecting unit 344L to the first detected unit 346L or from the second non-detecting unit 344R to the second detected unit 346H. As shown in the Y direction column 350Y in FIG. 15C, the first non-detecting unit 344L shifts to the first detected unit 346L or the second non-detecting unit 344R to the second detected unit 346H. In this case, 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. From the first detected unit 346L to the second non-detecting unit 344R, 2 First non-detection from detected part 346H When shifting to the knowledge unit 344L, the first light receiving unit 348R1 outputs the first pulse falling signal RF1, 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 part 346H or when shifting from the first non-detecting part 344L to the first detected part 346L, the second light receiving part 348R2 outputs the second pulse rising signal RE2 and the first The output of the light receiving unit 348R1 is L, when the second detected unit 346H shifts to the first non-detected unit 344L, or when the first detected unit 346L shifts to the second non-detected unit 344R. 348R2 outputs the second pulse signal falling signal RE2, and the output of the first light receiving unit 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, and hence the detection target 342.
More specifically, in FIG. 3A, when the moving unit 302 (roller 314) is rotated counterclockwise by the disc body 102, the detected body 342 is counterclockwise in FIG. And is moved in the first movement direction X in FIGS. Therefore, the combination of the first 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, and therefore is in the first half of the passage of the disc body 102. Can be determined. On the other hand, when the disc body 102 is ejected by the roller 314, the detected body 342 is rotated clockwise in FIG. 14A, so that the cylindrical portion 342P is moved in the second movement direction Y in FIG. . Therefore, the combination of the output signals from the first light receiving unit 348R1 and the second light receiving unit 348R2 is any one of the Y direction column 350Y in FIG. 15C, so that the disc body 102 passes through in FIG. 15B. It can be determined that it is in the second half of the way.

Next, the subtraction unit 362 will be described.
In the present embodiment, the subtracting unit 362 moves the moving direction from the first moving direction X to the second moving direction Y by the moving direction determining unit 360 from the count value Cnt stored in the counting unit 359 and therefore 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 Each time PSF2 is output, it has a function of subtracting one by one. However, the subtracting 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. When a payout signal DS, which will be described later, is output, the count value in the subtractor 362 is subtracted from the count value Cnt in the counter 359, and the value after subtraction is compared with the reference value PN as the maximum count value MC. May be.

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 comparison 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, plural, or a number that defines a predetermined range. In this embodiment, the edge reference value storage unit 364 has this function.
The edge reference value storage unit 364 has a function of storing a reference value PN for comparison with the count value Cnt in the edge counter 358 serving as a reference for determining whether or not 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 by the count unit 359, and thus the edge count unit 358. Therefore, when the disk body 102 is sent out without the rotator 116 being reversed, the count value Cnt and the maximum count value MC are the same, but the rotator 116 is being rotated while the rotator 116 is being reversed. It becomes a different value until halfway when is rotated forward again.

Next, the determination unit 366 will be described.
The determination unit 366 is based on the maximum count value MC (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 that is 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 away from the fixed portion 298 by a predetermined distance, when the moving portion 302 is moved by a predetermined amount by the disc body 102, The first pulse rising edge output from the PS1 rising edge detection unit 354 based on each of the first pulse signal PS1 output from the first light receiving unit 348R1 and the second pulse signal PS output from the second light receiving unit 348R2. The first pulse falling edge signal PSF1 output from the signals PSR1, PS1 falling edge detector 355, the second pulse rising edge signal PSR2 output from the PS2 rising edge detector 356, and the output from the PS2 falling edge detector 358 Of the second pulse falling edge signal PSF2 generated A predetermined number of signals are output at a predetermined timing, 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 body 102 and determine whether the disc body 102 is suitable. In the case of the disc body 102 having a diameter, for example, a 100 yen coin of Japanese yen is used as the disc body 102. If a 10 yen coin is mistakenly mixed, the diameter of the 100 yen coin is 22.6. Since the millimeter and 10-yen coins have a diameter of 23.5 millimeters, a difference of 0.9 millimeters is used as the first pulse based on the first pulse signal PS1. Based on the numbers of the 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 based on the second pal signal PS2, An abnormal signal ES1 is output. When the discriminating accuracy of the diameter of the disc body 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 By selecting and counting any one or more of the signals PSF2, it can be used as the count value Cnt.

Next, the disc discriminator 368 with holes will be described.
When receiving the hole detection signal HS from the center hole detection sensor 330 (FIG. 3), the holed disk body discriminating unit 368 determines that the holed disk body 102H is present, and the holed disk body 102H is inappropriate. If so, the second abnormal signal ES2 is output. For example, when a 100-yen coin having a diameter of 22.6 millimeters is used, if a 5-yen coin having a diameter of 22.0 millimeters is mistakenly mixed, 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 FIG. 5, the subtracting unit 362 is also reset and 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 by the count unit 359, and thus the edge count unit 358. Therefore, when the disk body 102 is sent out without the rotator 116 being reversed, the count value Cnt and the maximum count value MC are the same, but the rotator 116 is being rotated while the rotator 116 is being reversed. It becomes a different value until halfway when is rotated forward again.

Next, the operation of the disc body determination unit 294 will be described with reference to the flowchart of FIG.
First, subroutine processing for calculating the diameter of the disk body 102 will be described with reference to FIGS.
First, when the moving part 302 is moved away from the fixed part 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 includes the fixed part 298 and the moving part 302. 14A, the detected portion 342P is rotated counterclockwise in FIG. 14A, and thus moved in the arrow X direction in FIG. 14B. As a result, as described above, as shown in FIG. 15A, the first pulse signal PS1 is output from the first light receiving unit 348R1 and the second pulse signal PS2 is output from the second light receiving unit 348R2. 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. Become. Conversely, when the moving part 302 approaches the fixed part 298 to eject the disk body 102, in other words, the rear arcuate part BC on the rear end side in the traveling direction of the disk body 102 moves with the fixed part 298. 15B, when 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. The output relationship is Y direction column 350Y.
Therefore, in step S11 in the subroutine processing, the output from the first light receiving unit 348R1 is the first pulse rising signal RE1 of the first pulse signal PS1, and therefore the output from the PS1 rising edge detecting unit 354 is the first pulse rising edge signal PSR1 ( 13) and whether or not the output of the second pulse signal PS2 from the second light receiving unit 348R2 is “L”, and if it is a combination thereof, the process proceeds to step S15, and these combinations 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 detecting unit 355 is the first pulse falling edge signal PSF1 (FIG. 13), and whether or not the output of the second pulse signal PS2 from the second light receiving unit 348R2 is “H”, and if it is a combination thereof, the process proceeds to step S15, and is not a combination of these If so, the process proceeds to step S13.
In step S13, the output from the second light receiving unit 348R2 is the second pulse rising signal RE2 of the second pulse signal PS2, and therefore the output from the PS2 rising edge detecting unit 356 is the second pulse rising edge signal PSR2 and the first pulse signal PS2. It is determined whether the output of the first pulse signal PS1 from the light receiving unit 348R1 and therefore the first light receiving unit 348R1 is “H”. If it is a combination thereof, the process proceeds to step S15, and if not, the process proceeds to 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 detecting unit 357 is the second pulse falling edge signal PSF2, and Then, it is determined whether or not the output of the first pulse signal PS1 from the first light receiving unit 348R1 is “L”, and if it is a combination thereof, the process proceeds to step S15, and if not, the process proceeds to step S18.
In step S15, the counting unit 359 (edge counting unit 358) counts “1” in 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 smaller, the first routine is terminated, and if larger, 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 processing is terminated.
From the above, it is Step S15 that the output of the first light receiving unit 348R1 is the first pulse rising signal RE1, 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 unit 348R2 is “H”, the output of the second light receiving unit 348R2 is the second pulse rising signal RE2, and This is a case where 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 disc body 102 further moves the moving unit 302 away from the fixed unit 298, the processes of steps S11 to S17 are repeated. At the time of this repetition, one of the signal states occurs, so that “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 calculated 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 therefore the output from the PS1 rising edge detecting unit 354 is the first pulse rising edge signal PSR1, and It is determined whether the output of the second pulse signal PS2 from the second light receiving unit 348R2 is “H”, and if it is a combination thereof, the process proceeds to step S22, and if not, 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 therefore the output from the PS1 falling edge detecting unit 355 is the first pulse falling edge signal PSF1, and Then, it is determined whether or not the second pulse signal PS2 from the second light receiving unit 348R2 is “L”. If it is a combination thereof, the process proceeds to step S22, and if it is not a combination, 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, so the output from the PS2 rising edge detecting unit 356 is the second pulse rising edge signal PSR2, and the first It is determined whether or not the output of the first pulse signal PS1 from the light receiving unit 348R1 is “L”. If it is a combination of these, the process proceeds to step S22, and 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, and accordingly, the second pulse falling edge signal PSR2 from the PS2 falling edge detection unit 357, and the second It is determined whether or not the first pulse signal PS1 from the first light receiving unit 348R1 is “H”. If the first pulse signal PS1 is a combination thereof, the process proceeds to step S22, and if it is not a combination, the routine process is terminated.
Here, the conditions in steps S18 to S21 are satisfied in the case of the Y direction column 350Y in FIG. In other words, the moving unit 302 moves in a direction approaching the fixed unit 298. In other words, the moving part 302 is pushing the rear arcuate part BC on the rear side in the traveling direction of the disc body 102, that is, the disc body 102 is being paid out.
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 it is not 1 or more, the routine process is terminated. If it is 1 or more, the process proceeds to step S23.
In step S23, “1” is subtracted 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 the hole detection signal HS is output from the center hole detection sensor 330, and thus the second abnormal signal ES2 is output from the holed disc body determination unit 368. If not determined, the routine process is terminated and determined. If yes, go to Step S25.
If the second abnormality signal ES2 is output in step S25, the inappropriate disk body signal UCS is output, and the routine processing is terminated. In addition, based on the improper disk body signal UCS, the process with respect to the disk body 102 inappropriate in a related apparatus is performed.
When the normal disc body 102 is paid out 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 subtracted by “1”, and finally “0”. 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 process in FIG.
In step S1, it is determined whether or not the signal from the passage sensor 290 is “L”. When the signal from the passage sensor 290 is not “L”, in other words, while the disc body 102 is detected by the passage sensor 290, that is, while the payout signal DS is output, the step 1 is looped, If the payout signal DS from the passage sensor 290 is a signal “H” that is not present, in other words, if the disk 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 unit 359 (edge counting unit 358) and the maximum count value MC in the maximum count value storage unit 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 in the edge counting unit 358 is a predetermined value, for example, “0”. If the count value Cnt is greater than “0”, the process returns to step S3 to execute the subroutine processing, If the count value Cnt is “0”, the process proceeds to step S5. The predetermined value may not be “0” but may be a value close to “0”. This is because, when the accuracy of the disc body determination unit 294 is high, it may not return to the original position due to play of the mechanical part.
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 body 102 and has output a payout signal DS of output “L”. 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 disc body 102 is ejected by the moving unit 302 and detected by the passage sensor 290. 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 S <b> 7, the determination unit 366 determines whether the dispensed disk body 102 is an appropriate disk body 102. Specifically, if 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 is within the set range, the process returns to step S1, If they do not match or are not within the set range, the process proceeds to step S8.
In step S8, the determination unit 366 outputs the first abnormality signal ES1, in other words, the inappropriate disc body signal UCS, and then returns to step S1.
The inappropriate disk body signal UCS is used for processing the inappropriate disk body 102 in a device that uses the dispensed disk body 102.

Next, a unique case will be described with reference to FIG.
As shown in FIG. 18A, in the middle of paying out the disc body 102, as shown in FIG. That is, when the disc body 102 is bitten in the disc body delivery device 100, the rotating body 116 is reversed to eliminate the biting. Due to this reversal, the disk body 102 in the transport device 104 is also returned, so that the moving unit 302 is locked at the original buffer body 328 without paying out the disk body 102 by the return movement of the disk body 102. After being returned to (2), it may be pushed out again and paid out as shown in FIG.
In the state of FIG. 18A in this case, the moving part 302 is separated from the fixed part 298 by the front arcuate part FC on the front side in the traveling direction of the disc body 102. 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 is the first pulse falling. When the signal FE1 and the output of the second light receiving unit 348R2 are “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 it 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, each of the first pulse rising signal RE1 and the first pulse falling signal FE1 in the first pulse signal PS1 and each of the second pulse rising signal RE2 and the second pulse falling signal FE2 of the second pulse signal PS2. 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 counter 358, and biting occurs. Stopped at timing TS.
Thereafter, the rotating body 116 is reversed, and as a result, the rotating disk 132 is reversed, the disk body 102 is reversed, and the moving unit 302 approaches the fixed unit 298 or is then stopped by the buffer 328. In this case, as shown in FIG. 18B, the moving part 302 approaches the fixed part 298 under the restriction by the front arcuate part FC on the front side in the traveling direction of the disc body 102, so the Y direction column 350Y column 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 unit 348R2 are “L”, the output of the second light receiving unit 348R2 is the second pulse rising signal FE2 and the first light receiving unit. 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 counter 358 is sequentially subtracted one 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, when the bite of the disk body 102 is eliminated by the above-described reverse rotation, as shown in FIG. Since the plate member 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 in 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, when the output signal “L” is output from the passage sensor 290, in step S7 in the main routine process, 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 disc body 102 is a regular disc body 102. On the other hand, if the maximum count value MC and the reference value PN are different, it is determined that the disc body 102 is an inappropriate disc body. An improper disc signal UCS is output.
Therefore, in the present invention, even when the disc body 102 is returned in the middle of moving the moving unit 302, the count value Cnt in the counting unit 359 (edge counting unit 358 in this embodiment) is also subtracted. Therefore, the maximum count value MC of the final pulse signal for discriminating the diameter of the disc body 102 is the time when the disc body 102 is delivered, in other words, the disc body 102 is detected by the passage sensor 290. Since it is performed based on the maximum count value MC which is the count value Cnt in the counting unit 359 (edge counting unit 358) at the time of detection, the disc is not affected by the maximum count value MC during the payout. There is an effect that the diameter of the body 102 can be detected. Although the reverse rotation and the normal rotation of the rotating body 116 may be repeated a plurality of times, 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. In FIG. 19, the moving direction of the moving unit 302 is originally in the X direction depending on the state of the first detection signal PS1 from the first light receiving unit 348R1 and the second detection signal PS2 from the second light receiving unit 348R2. Or Y direction, for convenience, only the first detection signal PS1 is shown when moving in the X direction, and only the second detection signal PS2 is shown when moving 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 the sake of convenience, the description will be made assuming that each time the first pulse rising edge signal PSR1 is output, it is counted.
When the disc body 102 moves the moving part 302 in the direction away from the fixed part 298 by the normal rotation of the rotating body 116, the combination of the output of the first light receiving part 348R1 and the output of the second light receiving part 348R2 is as 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 by the edge counting unit 358, and is stopped at the timing TS at which biting occurs. Next, the rotating body 116 is reversed and the disk body 102 is returned. Accordingly, since the moving unit 302 moves in a direction approaching the fixed unit 298, the combination of the output of the first light receiving unit 348R1 and the output of the second light receiving unit 348R2 becomes a 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 counter 358 is sequentially subtracted by one. After the reverse rotation of the rotating body 116 is finished, the rotating body 116 is stopped and rotated forward again. Due to 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 sequentially counted as the count value Cnt in the edge counter 358. This operation is repeated until the 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, and the straight line is the disk. When it passes 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 in FIG. 15 is obtained, and the count value Cnt in the edge counting unit 358 is sequentially decremented by 1, 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 body 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 is output. 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 it is the same, it is determined that it is the regular disc body 102. A disc body signal UCS is output. As described in the prior art 1, when the disc body 116 is returned and the count value Cnt is not subtracted as in the present invention, the count value Cnt is greater than the maximum count value MC as shown in FIG. Is greater than the conventional first count value MCN1, and when a reverse pulse is added, the second count value MCN2 is greater than the conventional first count value MCN1. Therefore, in the first or second conventional technique, even if it is erroneously determined to be the predetermined disc body 102, in the present invention, the count value Cnt in the edge counting unit 358 which is the counting unit 359 is Therefore, the final determination for determining the diameter of the disc body 102 is performed in the middle, so that the maximum count value stored in the maximum count value storage unit 372 at the time when the disc body 102 is paid out is determined. Since MC is performed based on the count value Cnt in the edge counting unit 358, the diameter of the disk body 102 can be determined without being affected by the movement of the detected object 342 in the reverse direction during the payout. There is an effect.
