Description

Disc gauge with preventive device Field of invention

The present invention relates to a disc gauge that can separate discs one by one.

More specifically, there is a disc gauge that prevents the disc from being mishandled by the detection mechanism.

Further, the "disc" used in the present specification is a substitute currency or the like similar to a medal of a game machine or a token, in addition to a currency coin.

Background of the invention

The disc-shaped discs which are randomly stacked can be separately discharged by the rotating disc, and the disc counter is counted by the detecting disc member to be moved to the discharge position by the discharged disc, and the disc counter of the discharged disc is counted. In some cases, the rod member is used to force the aforementioned counting member to move to the discharge position, and the disc is not properly counted in the position without counting the discharge of the disc.

In the first conventional technique for preventing improperness, a blocking member that is interlocked with the aforementioned counting member and that advances and retreats at the discharge port of the disk is provided, and when the counting member is located at the discharge position, the blocking member is placed at the discharge port. And when the counting member is in the closed position, it is retracted by the discharge port, and thus operates in conjunction with each other.

In detail, the blocking member is located at the end of the discharge port, and the blocking member collides with the disk that is moved at a high speed by the rotating disk, and rebounds to a predetermined amount or more without being ejected by the discharge port (refer to Patent Document 1, for example). ).

In the second prior art, a known disc gauge system detects a roller that shakes the detecting base due to the disc during normal operation. When the abnormality occurs, the detecting roller pushes backward in the reverse direction, the disc cannot be thrown, and the disc is shaken. The susceptor is detected, and the rotating disk is rotatable (refer to Patent Document 2).

[Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-281588 (pages 1 to 6, pages 6 to 9)

[Patent Document 2] Japanese Laid-Open Patent Publication No. 2000-339508 (pages 1 to 5, pages 3 to 5)

In the first prior art, when the counting member is forcibly moved from the outside to the discharge position, the blocking member is located at the discharge port.

Thereby, the rotating disk is rotated at a high speed to collide with the blocking member, and as described above, is not discharged by the discharge port.

However, even when the blocking member is located at the discharge port, when the rotating disk is rotated at a low speed, the disk may not reach a predetermined amount due to the collision with the blocking member, and may be discharged by the discharge port.

At this time, since the counting member is located at the discharge position, it is impossible to detect the discharged disc, and there is a possibility that the disc is improperly obtained.

Moreover, since the interlocking mechanism of the counting member and the blocking member uses a spring or the like, it is expensive and cannot be used.

In the second prior art, when the detecting roller is forcibly moved to the discharge position, the rotating disk shakes the detecting base via the detecting roller.

When the detection base is shaken, the detection mechanism detects this, so the disc cannot be improperly obtained.

However, the rotational resistance of the rotating disk will increase significantly and will increase the electrical Consumption is therefore difficult to adopt.

A first object of the present invention is to reliably prevent improper acquisition of a disk in a disk gauge.

The second object of the present invention is to prevent the rotation resistance of the rotating disk of the discharge disk from being greatly increased, and to prevent the disk from being improperly obtained.

A third object of the present invention is to provide a disc gauge having an improper prevention device at a low price.

Summary of invention

To achieve this, the disc gauge of the present invention having an improper prevention device is constructed as follows.

A disc meter provided with an anti-missing device, comprising: a rotating disc having a pushing portion for feeding the disc; and a first guiding portion disposed on a side of the rotating disc in a fixed state; The second guiding portion is located on a side surface of the first guiding portion and the rotating disk, and is movable to a standby position at a distance from the first guiding portion below the diameter of the disk, and by the circle a discharge position of the disk and a disk passing detection mechanism; a discharge passage for allowing the first guide portion and the second guide portion to move; and an obstruction mechanism for the second guide portion The movement is interlocked, and when the second guiding portion is located at the discharge position, the second guiding portion is located in the discharge passage, and when the second guiding portion is at the standby position, the second discharge portion is retracted from the discharge passage. The obstruction mechanism is that the disc that is fed out by the ejecting portion of the disc is stopped in the discharge passage.

According to this configuration, the circle can usually be pushed by the push-out portion of the rotating disk The disk is thereby guided by the first guiding portion and moves the second guiding portion.

The obstruction mechanism moves in and out of the discharge passage in conjunction with the second guide portion.

In detail, when the second guiding portion is located at the discharge position, the obstruction mechanism is located in the discharge passage to prevent the passage of the disc.

When the second guiding portion is at the standby position, the obstruction mechanism is retracted by the discharge passage.

After the diameter portion of the disk passes between the first guiding portion and the second guiding portion, the disk can be more strongly ejected to the discharge path by the potential energy of the second guiding portion.

Therefore, when the disk reaches the obstruction mechanism, the obstruction mechanism can be ejected from the discharge path in conjunction with the movement of the discharge position of the second guide portion to the standby position, so that the disc can be ejected without being blocked by the obstruction mechanism.

By the movement of the second guiding portion, the disk passing detection means can detect the discharge of the disk and output a detection signal. Therefore, by counting the detection signal, the total number of discharges of the disk after the start of discharge can be counted.

Thereby, the first disk is pushed out by the pushing portion to the discharge path, and the diameter portion passes between the first guiding portion and the second guiding portion, and can be stopped by the blocking mechanism.

Therefore, the next disk does not block the disk of the first piece and moves to the discharge path.

Thereby, the next disc is guided to the rear end of the aforementioned first disc and is pushed by the pushing portion of the rotating disc and moved simultaneously with the rotating disc.

When the disc in which the obstruction member is stopped is discharged, since the obstruction mechanism can be forcibly moved by the disc, the second guide portion moves to the discharge position.

Thereby, the movement of the second guiding portion can be detected directly or indirectly by the disk The mechanism detects and thereby detects the discharge of the disc.

Therefore, there is an advantage that the disc which can be counted and discharged can be surely counted.

In the present invention, it is preferable that the second guiding portion and the obstructing mechanism are respectively attached to one end portion and the other end portion of the rocking lever that can pivotally move, and the action piece that moves integrally with the rocking lever constitutes the disc passing detection. Part of the organization.

According to this configuration, the second guiding portion and the blocking mechanism are attached to the rocking lever that can move the pivot point, and the action piece that moves integrally with the rocking lever constitutes the disk passing detecting mechanism.

Therefore, since the structure is simple, there is an advantage that it can be manufactured inexpensively.

Moreover, the present invention preferably has a circumferential direction guiding device that protrudes from a moving path of the disk that is rotated by the rotating disk, and guides the disk toward the circumferential direction of the rotating disk. When the circumferential direction guiding device receives a predetermined force from the disk, it can be retracted by the moving path.

According to this configuration, the circumferential direction guiding means protrudes from the movement path of the disk which is rotated by the rotating disk, and the disk which is rotated by the circumferential direction guiding means is guided to the circumferential direction of the rotating disk.

In detail, if the ratio of the diameter of the rotating disk to the diameter of the disk is not more than a predetermined value, the disk cannot be ejected only by the pushing portion, but even if it is below the diameter ratio, the disk can be borrowed. The circumferential direction guiding device is guided in the circumferential direction of the rotating disk.

When the first disc stops at the obstruction mechanism, the circumferential direction guide pushes the subsequent disc and is retracted by the moving path.

Thereby, the disc will rotate at the same time as the rotating disc.

In other words, even the disc meter having a small diameter of the rotating disc having the circumferential direction guiding means is applicable to the present invention, and has the advantage of reducing the energy consumption of the disc meter.

Further, the circumferential direction guiding device of the present invention is fixed to the restricting body of the rocking lever, and the rocking lever can be pivoted about the axis as a center, and is given a potential energy mechanism to impart elasticity to the rotating disk. Further, the axis is in a plane parallel to the rotating disk and located below the bottom of the disk movement.

By this configuration, when the disc pushes the pin, the contact position of the disc with the pin is offset from the axis of the gauge, so the rocking rod is subjected to the moment of the rotating disc.

Generally, a disk driven by a rotating disk is subjected to centrifugal force and has a force in the circumferential direction.

Therefore, when the disc is guided by the pin, the pin does not receive a large force.

In other words, when the disk is driven by the rotating disk, the rotation resistance of the pin acting on the rotating disk is extremely small.

Therefore, it has the advantage of small power consumption.

The frame 104 includes a base 122 and a rectangular tubular support portion 124 fixed to the base 122.

The hollow portion of the support portion 124 is provided with an electric motor for driving the control substrate and the rotating disk 110, and the head portion is formed in an oblique direction.

Next, the gauge base 106 will be described.

The meter base 106 has a function of holding the rotating disk 110, the circumferential guiding device 122, the discharging device 114, the disk passing detecting mechanism 116 and the preventing improper device 118 at a predetermined position, and guiding the rotating disk 110 to move. The function of the disc 102.

The gauge base 106 is in the form of a rectangular thick plate and is fixed to the top of the support portion 124.

In other words, the gauge base 106 is tilted by a predetermined angle.

As shown in Fig. 2, the gauge base 106 includes a guide hole 132 having a bottom portion at the center of the upper surface 130, and a first mounting portion 134A, 134B formed on the upper and lower end portions of the retaining disk 108; Second mounting portion 136A, 136B, a discharge opening 138 opening in one of the peripheral faces of the guide hole 132, a disk passing through the mounting portion 140 of the detecting mechanism 116, and a mounting portion 142 of the circumferential direction guiding device 112.

The bottom 144 of the guide hole 132 is mostly planar, and a shaft hole 148 is formed in the center through the rotating shaft 146 on which the rotating disk 110 is mounted.

The disk 102 pushed by the rotating disk 110 slides under the bottom portion 144, and its peripheral surface is movable along the peripheral wall 150 of the guiding hole 132.

The locking portion (not shown) formed on the lower portion of the retaining disk 108 is locked to the first mounting portions 134A, 134B and the second mounting holes 136A, 136B, whereby the retaining disk 108 can be easily manipulated and detached from the disk gauge. ,installation.

A discharge device 114 to be described later is disposed beside the discharge opening 138.

Hereinafter, the reserve disk 108 will be described.

The retaining disk 108 has the function of storing the disk 110 in any state.

The lower end portion 152 of the retaining 108 is cylindrical in shape having a diameter substantially the same as that of the guide hole 132, and extends in a direction orthogonal to the gauge base 106.

In other words, the lower end portion 152 extends obliquely upward, and the upper end portion thereof is formed with a quadrangular enlarged storage portion 154, and the upper end serves as the disk insertion opening 156.

The storage portion 154 of the retaining disk 108 and the lower end portion 154 are connected by an inclined wall, and the disk 102 carried thereon is free to slide by gravity and falls on the rotating disk 110 below.

Next, the rotating disk 110 will be described.

The rotating disk 110 has a function of separately discharging the disks remaining in the free standing state to the discharge tray to the discharge device.

A disk-shaped rotating disk 110 is disposed in the guide hole 132.

The rotating disk 110 is rotationally driven via a reduction gear by an electric motor (not shown).

The rotary disk 110 is formed at equal intervals to form a circular through hole 160, and the upper side of the through hole 160 is formed with a downwardly tapered introduction portion 162.

Further, the central portion is formed in a conical shape and attached to the central portion 164 of the rotating shaft 146.

The circumferential surface of the rotating disk 110 is disposed in the guiding hole 132 with a slight gap therebetween.

The first push-out portion 168 and the second push-out portion 170 for ejecting the disk 102 are formed opposite to the respective through holes 160 in the inside of the rib 166 of the through hole 160 for dividing the rotating disk 110.

The lead-out surfaces 172 and 174 (see FIG. 8) of the first push-out portion 168 and the second push-out portion are located on an internal rotation curve extending from the center portion of the rotary disk 110.

A gap 176 through which the restriction pin to be described later passes is formed between the first push-out portion 168 and the second push-out portion 170.

The circumferential direction guiding device 112 will be described below.

The circumferential direction guiding device 112 has a function of guiding the disk 102 pushed by the first pushing surface 172 and the second pushing surface 174 to the circumferential direction of the rotating disk 110 and inducing it to the discharge opening 138.

Specifically, the first through hole 177 and the second through hole 178 that penetrate the meter base 106 from the lower side to the upper side are disposed, and are a column extending toward the rotating disk 100 and are pin-shaped first restricting bodies 180 And the second restriction body.

In other words, the first restricting body 180 and the second restricting body 182 protrude from the movement path 183 of the disk 102 (see FIG. 9).

The restricting bodies 180, 182 are attached to the retracting device 184 installed inside the gauge base 106.

Further, any one of the first restriction body 180 and the second restriction body 182 may satisfy the above functions.

Further, when the first restricting body 180 and the second restricting body 182 are not used and the disk 102 can move toward the discharge opening 138, it is not necessary to arrange.

In other words, if the diameter of the rotating disk 110 is large, the disk 102 can be induced in the circumferential direction of the rotating disk 110 only by the first pushing portion 168 and the second pushing portion 170, and the restricting bodies 180 and 182 need not be disposed.

When the first restricting body 180 or the second restricting body receives a predetermined lateral force from the disk 102, the first restricting body 180 and the second restricting body 182 are respectively retracted from the first through hole 177, and 2 The through hole 178, and the disk 102 can be moved simultaneously with the rotating disk 110.

The retracting device 184 includes a support shaft 188, a rocking lever 190, and a potential energy mechanism 192.

The fulcrum 188 projects laterally from the middle of the rocker bar 190 and has its axis 189 located below the bottom 144 of the meter base 106 and is disposed in a plane substantially parallel to the bottom 144 and is mounted to the meter base 106. The bearing 186 protrudes therein and is free to rotate.

Further, the support shaft 188 is disposed on the outer peripheral side of the rotating disk 110 of the first restricting body 180 and the second restricting body 182.

Further, the support shaft 188 is disposed such that when one of the discs 102 is stopped by the obstruction mechanism 118, which will be described later, the disc 102, which will be described later, is pushed in a direction orthogonal to the axis 189 in plan view.

A plate spring 192 is fixed to the upper surface of the rocking lever 190, and the first restricting body 180 and the second restricting body 182 are fixed to one end of the leaf spring 192 at right angles to the rocking lever 190.

An energizing energy mechanism 192 is disposed between the other end of the rocking rod 190 and the inside of the meter base 106. In this embodiment, a spring 194 is disposed.

Thereby, the rocking lever 190 is given a potential energy, and the first restricting body 180 and the second restricting body 182 are protruded from the bottom 144 of the gauge base 106 toward the inside of the rotating disk 110.

In other words, the swing lever 190 is fulcrum-moving with the support shaft 188 at a position where the portions of the first restricting body 180 and the second restricting body 182 are in contact with each other.

The upper surface of the rocking lever 190 is locked to the inside of the gauge base 106, and is held at a position where the first restricting body 180 and the second restricting body 182 are almost perpendicular to the bottom portion 144.

Further, the support shaft 188 is disposed such that its axis 189 is orthogonal to the direction D (see Fig. 9) of the force received by the disk 102 as viewed in plan.

Therefore, when the disk 102 sliding on the bottom portion 144 presses the first restricting body 180 or the second restricting body 182. The first restricting body 180 or the second restricting body 182 is moved back to the first through hole 177 and the second through hole 178 with the support shaft 188 as a fulcrum.

Further, an elliptical cylindrical guide portion 196 projecting toward the gauge base 106 is formed in the rocking lever 190, and is slidably inserted into a guide hole (not shown) formed in the inside of the gauge base 106.

Thereby, the guiding portion 196 is guided by the guiding hole and swings the rod 190 to the fulcrum 188 is shaking for the fulcrum.

Further, the first restricting body 180 and the second restricting body 182 can be directly attached to the swing lever 190 without providing the leaf spring 192.

The discharge opening 138 will be described below.

The discharge device has a function of ejecting the discs 102 which are separately fed out by the rotary disk 110 one by one.

The discharge device 114 includes a first guide portion 200, a second guide portion 202, a potential energy supply mechanism 204, and a discharge passage 208 defined by the passage restriction guide portion 206.

First, the first guiding unit 200 will be described.

The first guiding portion 200 forms a side wall through which the disc 102 can exit the passage 208 and has a function of guiding the disc 102 to a predetermined position.

The first guiding portion 200 is a plate-shaped plate fixed to the bottom 197 of the discharge passage which is located on the same plane as the bottom portion 144, and the side surface 210 is formed in an arc shape to constitute a part of the guiding hole 132.

In the present embodiment, the first guide portion 200 is a plate-shaped plate, but it can be changed to a roller that can be freely rotated by being attached to a fixed shaft.

Next, the second guiding unit 202 will be described.

The second guiding portion 202 has a disk 102 that can be ejected between the first guiding portion 200 and the first guiding portion 200.

The second guiding portion is disposed on the side surface of the rotating disk 110 and the first guiding portion 200, and constitutes one side wall of the discharge passage 208.

The second guiding portion 202 is a roller 220 that is rotatably attached to a support shaft 218 fixed to the swing lever 216, and the swing lever 216 is attached to a fixed shaft fixed to a passage restricting guide 206 to be described later. 214 and can be solid The fixed axis is the fulcrum rotation.

Specifically, the potential energy mechanism 204 is locked between the support shaft 218 and the pin 222 fixed to the passage restriction guide 206, and the rocking rod 216 is brought close to the potential of the first guide portion 200.

The energizing potential mechanism 204 has a function of giving the second guiding portion 202 elastically close to the first guiding portion 200.

Generally, the integrally formed locking portion 224 is locked to the locking portion 228 of the passage restricting guide portion 206, and the rocking lever 216 is stopped at an interval from the diameter of the first guiding portion 200 that is smaller than the diameter of the disk 102, and Still at the standby position SB.

When the diameter portion of the disk 102 moves between the first guiding portion 200 and the second guiding portion 202, after the second guiding portion 202 moves to the discharge position DP, the elastic force of the potential energy mechanism 204 is ejected. Disk 102.

Further, the second guiding portion 202 performs the fulcrum movement by the swing lever 206, but the shift is closer to the first guiding portion 200 by the linear motion.

Further, the energizing potential mechanism 204 can be changed to a device having the same function as an electromagnetic actuator or an air actuator, in addition to being more variable in spring.

The second guiding portion 202 can guide non-rotation like the first guiding portion 200.

However, as shown in Fig. 7(B), it is preferable that the lower end of the support shaft 218 has a small diameter smaller than the outer diameter of the roller 220, and the circular disc 228 having the same diameter as the roller 220 can be disposed. The roller 220 is interposed between the roller lever 216, whereby the roller 220 is not easily damaged by the outside.

Moreover, the support shaft 218 can be supported by both ends for the same purpose.

Hereinafter, the path restriction guide 206 will be described.

The passage restriction guide 206 has a function of delimiting the upper wall of the discharge passage 208.

The passage restricting guide 206 is tightly inserted between the left side wall 199 and the right side wall 198 of the discharge opening 138, and presses the first guide portion 200 from the upper side, and is fixed to the first guide portion 200 by the fixing pin 222. Meter base 106.

The disc 102 discharged by the discharge device 114 is discharged from the outlet 226 of the discharge passage 208 located on the left side of the gauge base 106.

The locking portion 228 is disposed on one end surface of the passage restricting guide portion 206 and is in surface contact with the locked portion 224 of the swing lever 216.

By the surface contact preventing the rocking lever 216, the durability of the locking portion 228 can be improved, and the rebound of the rocking lever 216 can be prevented.

Next, the disk passing through the detecting mechanism 116 will be described.

The disk passing detection mechanism 116 has a function of directly or indirectly detecting the disk 102 to cause the movement of the second guiding portion 202 and then outputting a detection signal.

The disk passing detection mechanism 116 of the present embodiment includes a first guiding portion 202, a rocking lever 216 that supports the second guiding portion 202, an action piece 230 that moves in conjunction with the swing lever 216, and a detecting mechanism of the action piece 230. 232.

The action piece 230 is formed on the front end portion of the wrist 236 which is integrally formed with the rocking lever 216 and which is the interlocking mechanism 234, and is located on the circular arc around the fixed shaft 214.

As shown in FIG. 4, the rocking lever 216 located on the surface side of the gauge base 106 and the detected portion 238 located on the back side are coupled via a wrist 236 located in the long hole 231 penetrating the gauge base 106.

The detecting mechanism 232 has an output that can be outputted or cut when detecting the detected portion 238 Broken electrical detection signal DS function.

The detection mechanism 232 of the embodiment includes a sensor 244 and a detection signal output signal 246.

The sensor 244 is a transmissive photodetector in which one of the gate-shaped pillars 248 is disposed on the light projecting portion 250 and has a light-receiving portion 252 disposed opposite to the light-projecting portion 250.

The sensor 244 has its inner side secured to the gauge base 106 via a bracket 256.

Therefore, in this embodiment, the sensor 244 is located below the gauge substrate 106 surrounded by the support portion 124, so it is difficult to perform an improper access system externally to the sensor 244.

When the second guiding portion 202 moves to the discharge position DP by the disk 102, the detected portion 238 cuts the projection light from the light projecting portion 250 to the light receiving portion 252.

With this truncation, the output of the sensor 244 changes from "H" to "L".

When the second guiding portion 202 is located at the standby position SB from the discharge position DP, the detected portion 238 is separated from between the light projecting portion 250 and the light receiving portion 252, so that the output of the photodetector 244 is changed from "L" to "H". "."

By counting the detection signal DS, the number of discs 102 that have been ejected can be known.

Further, the disk passing detection mechanism 116 can be constructed by directly detecting the movement of the rocking lever 216 or the roller 220.

The improper device 118 is explained below.

Preventing the improper device 118 from preventing the disk from being ejected only by the detecting mechanism 116 when the second guiding portion 202 is moved from the outside to the discharge position DP 102 does not output the function of the detection signal DS.

The prevention device 118 is an obstruction mechanism 260 that is interlocked with the second introducer 202 and that moves toward the discharge passage 208 on the downstream side of the discharge device 114.

In the first embodiment, the obstruction mechanism 260 is attached to the obstruction member 266 of the second support shaft 264 fixed to the end of the second rod 262, and the second rod 262 is opposite to the fixed shaft 214 with respect to the swing lever 216. Side extension.

The hindrance member is attached to the second support shaft 264 and is rotatable about the roller 268, but it is preferably a surface having durability or the like, and can be changed to a columnar fixed barrier sheet.

The obstruction member 266 can protrude through the arcuate long hole 270 formed in the passage restriction guide 206 and protrude toward the discharge passage 208.

When the second guiding portion 202 is located at the standby position SB, the obstruction member 266 is located at the liberation position FP whose distance from the side wall 272 of the first guiding portion 200 is greater than or equal to the diameter of 102.

At this time, the action piece 230 is positioned to block the projected light from the light projecting portion 250 as described above.

When the second guiding portion 202 is located at the discharge position DP, the obstruction member 266 moves to the obstruction position OP which is spaced apart from the side wall 272 of the first guiding portion 200 by the diameter of the disk 102.

Therefore, when the disk 102 passes between the blocking member 266 and the side wall 272, the blocking member 266 moves to the liberation position FP.

When the obstruction member 266 is moved to the liberation position FP, the second guide portion 202 that is looped by the linkage mechanism 234 moves to the standby position SB, so that the action piece 230 is moved from the detection position to the non-detection position.

Therefore, the output of the detecting means 232 is changed from "L" to "H", so the detection signal output means 246 outputs the detection signal DS.

In other words, when the disc 102 is ejected from the outlet 266, the obstruction member 266 is moved from the obstruction position OP to the liberation position FP, and thus the detection signal DS is outputted by the detection signal output mechanism 246.

The action of Embodiment 1 will be described below also with reference to Figs. 8 to 11.

When the discharge signal indicating signal of the disk 102 is received, the motor rotates (not shown), and the rotating disk 110 rotates in the clockwise direction as shown in FIG. 2 via a speed reducer and a rotating shaft 146 (not shown). .

By the rotation of the rotating disc 110, the disc 102 will fall on the through hole 160 and be pushed by the first push preliminary 168, the lower surface of which will slide on the bottom 144 of the guiding hole 132, and the peripheral surface will be guided by the peripheral wall 150 and The first restriction body 180 and the second restriction body 182 are reached.

The disk 102 is guided to the circumferential direction of the guide hole 132 by the first restricting body 180 and the second restricting body 182.

At this time, the first restricting body and the second restricting body 182 are biased by the lateral direction. However, since the elastic force imparted to the potential energy mechanism 192 is rotated upward, the first restricting body 180 and the second restricting body 182 can be held to the bottom portion 144. The state of the vertical.

The disk 102 is moved in the circumferential direction by the disk 102, and the disk 102 reaches between the first guiding portion 200 and the second guiding portion 202 (see Fig. 8).

The disk 102 is further pushed to the circumferential direction by the first pushing portion 168 and then the second pushing portion 170, and the first guiding portion 200 is fixed. Therefore, the second guiding portion 202 can be supported by the disk 102. The position of Fig. 8 moves obliquely upward to the right.

Thereby, the rocking lever 216 is centered on the fixed shaft 214 and counterclockwise. Swirl.

When the second guiding portion 202 moves due to the disk 102, the action piece 230 that performs the fulcrum motion integrally with the swing lever 216 blocks the projection light from the light projecting portion 250 of the sensor 244, and thus will be as the 11th ( A) As shown in the figure, its output changes from "H" to "L".

Further, the obstruction member 266 is moved to the obstruction position OP by the liberation position FP via the second rod 262.

After the disk 102 passes between the first guiding portion 200 and the second guiding portion 200, the disk 102 is biased by the potential energy mechanism 204 via the second guiding portion 202, and is discharged from the outlet passage 208 by the outlet 226. discharge.

As a result, the second guiding portion 202 returns to the standby position SB, so that the obstruction member 266 is interlocked and returns to the liberation position FP.

Therefore, the disk 102 ejected by the second guiding portion 202 is not blocked by the blocking mechanism 266, but is discharged by the outlet 226.

Further, since the action piece 230 is separated from the detection position of the sensor 244 by the restoration operation of the second guide unit 202 to the standby position SB, the projection light from the light projecting unit 250 receives the light from the light receiving unit 252.

Thereby, the output of the sensor 244 changes from "L" to "H" as shown in Fig. 11(B).

The detection signal output unit 246 outputs the detection signal DS in accordance with the change in the output from "L" to "H".

Therefore, by counting the detection signal DS, the number of discs 102 discharged from the outlet 226 can be counted.

Next, as shown in FIG. 10, the second guide portion is referred to by the rod portion T or the like. An example in which 202 is forced to move to the discharge position DP will be described.

At this time, the obstruction member 266 is held at the obstruction position OP in conjunction with the movement of the second guiding portion 202.

Thereby, the disc 102 guided to the first restricting body 180 and the second restricting body 182 is prevented from being blocked by the obstruction member 266 when the passage 208 is discharged, and is stopped substantially at the outer periphery of the guide hole 132 at the rear end of the disc 102. status.

By the continuous rotation of the rotating disk 110, the subsequent disk 102 can push the first restricting body 180 laterally by preventing the rear end of the disk 102 from being guided.

By this pushing, the first restricting body and the second restricting body 182 are subjected to a force acting in a direction D which is substantially perpendicular to the axis 189 of the pivot shaft 188 of the rocking lever 190 as viewed in plan.

Thereby, the first restricting body 180 and the second restricting body 182 are retracted by the moving path 183 by the evacuation device 184.

That is, the swing lever 190 is biased at a position where the support shaft 188 is displaced, and thus the fulcrum movement is centered on the support shaft 188 in the counterclockwise direction in the sixth (A) diagram.

Therefore, as shown in the sixth (B) diagram, the first restricting body 180 and the second restricting body 182 move the head portions into the first through holes 177 and the second through holes 178, respectively.

In other words, the first restricting body 180 and the second restricting body 182 are withdrawn from the moving path 183 of the disk 102.

Thereby, the disk 102 is prevented from being moved by the first restricting body 180 and the second restricting body 182, and can be rotated together with the rotating disk 110.

Therefore, there is an advantage that an excessive load is not caused to the drive motor (not shown) of the rotating disk 110.

Moreover, the second guiding portion 202 is continuously held at the discharge position DP, and thus The slice 230 can continue to be detected by the sensor 244.

That is, as shown in Fig. 11(C), the output of the sensor 244 continues to be "L", and therefore, the detection signal DS is not output by the detection signal output means 246.

In other words, when the disc 102 is blocked by the obstruction member 266, the detection signal DS is not output, and the discharge of the disc 102 is not counted.

When the second guiding portion 202 is continuously held and released, the blocking member 102 prevents the moving disk 102 from being pushed by the second guiding portion 202 that returns to the standby position SB by the potential energy imparted to the potential energy mechanism 204.

Since the obstruction mechanism 266 moves in conjunction with the movement of the second guiding portion 202 to the standby position SB and moves to the liberation position FP, the disk 102 is discharged from the outlet 226.

At this time, the action piece 230 does not cut off the projected light from the light projecting portion 250 of the sensor 244.

Therefore, as indicated by the symbol E in the 11th (C) diagram, the output of the sensor 244 is changed from "L" to "H".

Thereby, as shown in Fig. 11(D), the detection signal output unit 246 outputs the detection signal DS, and therefore the detection signal DS is used for the number of discharges of the counting disk 102.

Therefore, since the disk 102 is discharged from the outlet 226, the detection signal DS must be output, so that there is no disk 102 that is discharged without being counted.

In other words, it is possible to prevent the disc 102 from being discharged without counting.

[Example 2]

Embodiment 2 of the improper prevention device 118 will be described with reference to Figs.

Figure 12 is a schematic view of Embodiment 2.

Fig. 13 is a view showing the action of the embodiment 2.

Fig. 14 is a view showing the action of the embodiment 2.

The same portions as those in Embodiment 1 are given the same reference numerals to explain different configurations.

First, the action piece 230 will be described.

The action piece 230 is disposed below the bottom plate 106 and has an arc shape centering on the fixed shaft 300 at one end of the L-shaped rocking body 302.

Next, the second guiding unit 202 will be described.

The third side shaft 304 fixed to the other end portion of the rocking body 302 is inserted into the arc side long hole (not shown) centering on the fixed shaft 300 of the bottom plate 106 toward the front side, and is located at the side of the rotating disc 110. Pathway 208.

The roller 220 as the second guiding portion 202 is attached to the middle of the third support shaft 304 and is rotatable and is located in the discharge passage 208.

The rocking body 302 is biased between the lower end portions of the pins 222 projecting toward the inner side of the bottom plate 106 and is provided as a spring 224 imparting the potential energy mechanism 204 to the potential of the first guiding portion 200.

Further, the swinging body 302 is stopped by a stopper (not shown) so that the interval between the second guiding portion 202 and the first guiding portion 200 is smaller than a predetermined distance of the diameter of the disk 102.

This rest position is the standby position SB of the second guiding portion 202.

Next, the obstacle mechanism 260 will be described.

The obstruction mechanism 260 is attached to the obstruction member 266 of the support shaft 310 fixed to one end of the restriction lever 308, specifically, a roller, and the restriction lever 308 is mountable to a fixed shaft fixed to the passage restriction guide 206. On 306, The fixed shaft 306 is used as a fulcrum motion.

The restricting lever 308 is biased between the latching lever 222 and the second energizing potential mechanism 312 to impart a potential energy in the clockwise direction of FIG. 12 to the liberating position FP.

Next, the oscillating body 302 and the restricting lever 308, in other words, the interlocking mechanism 234 of the action piece 230 and the obstruction mechanism 260 will be described.

The interlocking mechanism 234 has a function. When the blocking mechanism 260 moves to the blocking position OP, the action piece 230 is detected by the detecting mechanism 232. When the blocking mechanism 260 is located at the liberating position FR, the acting piece 230 is not detected by the detecting mechanism 232. .

A semicircular hook portion 314 that hooks the upper end portion of the third fulcrum 304 is formed at the other end of the restricting lever 308.

When the obstruction member 266 is held at the liberation position FP and the hook portion 314 is locked to the front end of the third fulcrum 304, the oscillating body 302 does not move as a fulcrum in the clockwise direction of FIG.

In other words, when the obstruction mechanism 260 is at the liberation position FP, the third fulcrum 304 is pushed by the hook portion 314 of the restriction lever 308 to be forcibly moved to the standby position SB.

Thereby, the action piece 230 is moved by the detection area of the sensor 244, and the output of the sensor changes from "L" to "H", so the detection signal output means 246 outputs the detection signal DS.

Further, a support shaft 316 projecting from the inside of the restriction lever 308 toward the discharge passage 208 is provided, and a leading passive roller 320 as a preceding passive body 318 is attached to the front end portion thereof and is rotatable.

The disc 102 guided by the second restricting body 182 and the first guiding portion 200 pushes the second guiding portion 202 and the preceding passive roller 320 at substantially the same time point, and then causes the restricting lever 308 to face the counterclockwise in FIG. The direction is swivel.

Thereby, the hook portion 314 moves in the same direction and is separated from the third support shaft 304.

Moreover, the disk 102 pushes the second guiding portion 202, and after the diameter portion of the disk 102 passes between the first guiding portion 200 and the second guiding portion 202, the disk can be ejected by the potential energy of the potential energy mechanism 204. 102.

Next, the effect of Embodiment 2 will be described.

First, the effect of normal time will be explained.

The disk 102 rotated by the rotating disk can be guided to the circumferential direction of the rotating disk 102 by the first restricting body 180 and the second restricting body 182, and reaches the entrance of the discharge passage 208.

Thereby, a part of the disk 102 is guided by the first guiding portion 200, and the second guiding roller 202 and the preceding passive roller 320 are pushed.

By the pushing of the second guiding portion 202 by the disk 102, the rocking body 302 resists the potential energy of the potential energy mechanism 204 and rotates in the clock direction in Fig. 12 (refer to Fig. 13).

Thereby, since the action piece 230 blocks the projection light of the sensor 244, the output of the sensor 244 is changed from "H" to "L" as in the first embodiment.

Similarly, since the disk 102 pushes the preceding passive body 318, the restriction lever 308 is rotated in a counterclockwise direction opposite to that in standby, and the blocking member 266 is moved to the obstruction position OP.

After the diameter portion of the disk 102 passes between the first guiding portion 200 and the second guiding portion 202, the rocking body 302 is biased toward the counterclockwise by the potential energy mechanism 204. Since the direction is rotated, the disk 102 is bounced by the second guiding portion 202.

The bouncing disc 102 passes before the preceding passive body starts the return of the second energizing mechanism 312, and thus is not blocked by the preceding passive body 318.

If the bouncing disc contacts the preceding passive body 318, the disc 102 will push the preceding passive body 318 and then pass by the potential energy of the movement.

By the fulcrum motion of the counterclockwise direction of the shaking 302, the action piece 230 will move outside the detection range of the sensor 244, so the output of the sensor 244 will change from "L" to "H".

Therefore, the detection signal output means outputs the detection signal DS in accordance with the change of "L" to "H" in the same manner as in the first embodiment.

By counting the detection signal DS, the number of discharged disks 102 can be counted.

After the disc 102 passes the side surface of the passive body 318, the restriction lever 308 is rotated in the clock direction by the second biasing mechanism 312, so that the obstruction mechanism 206 is moved from the obstruction position OP to the liberation position FP.

Thereby, the disc 102 can be discharged from the outlet 226 without being obstructed by the obstruction mechanism 260.

Next, the case where the second guiding portion 202 is forcibly moved will be described.

When the rod-shaped body T is inserted from the outlet 226 and the second guide portion 202 is forcibly moved in the same manner as in the first embodiment, in other words, when the swinging body 302 is rotated in the clock direction via the second guiding portion 202, the swinging body 302 faces the first 12 The clock direction is rotated.

Thereby, the same action piece 230 enters the detection area of the sensor 244 as described above, so the output of the sensor 244 changes from "H" to "L".

However, the detection signal output unit 246 does not output the detection signal DS.

When the second guiding portion 202 is held at the discharge position DP, the preceding passive body 318 can prevent the return by the disk 102. Therefore, the blocking mechanism 260 continues to be positioned at the blocking position OP (see Fig. 13).

When the obstruction mechanism 260 is located at the obstruction position OP, the distance from the side surface 258 of the first guide portion 202 is smaller than the diameter of the disc 102. Therefore, the disc 102 is prevented from moving by the obstruction mechanism 260 and is retained in the discharge passage 208.

In the same manner as in the first embodiment, the disk 102 is retracted from the first through hole 177 and the second through hole 1785 by the first restricting body 180 and the second restricting body 182, and is rotatable with the rotating disk 110.

Therefore, the motor (not shown) for driving the rotating disk 110 does not have an excessive load.

If the obstruction mechanism 260 prevents the moving disc 102 from passing the position of the obstruction mechanism 260, the obstruction mechanism 260 can be moved to the liberation position FP by the disc 102.

In other words, the restricting lever 308 pivots in the clock direction with the fixed shaft 306 as a fulcrum.

Thereby, the hook portion 314 is hooked to the third pivot shaft 304, and the rocking body 302 is rotated in the counterclockwise direction.

By the rotation of the rocking body 302, the action piece 230 will move out of the detection range of the photodetector 244, so the output of the sensor 244 will change from "L" to "H".

The detection signal output unit 246 outputs the detection signal DS in the same manner as in the first embodiment.

Therefore, when the disc 102 is ejected from the outlet 226, a detection signal must be output. No. DS, so the disc 102 will not be ejected without counting.
