Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a discharge device for taking out articles one by one from an article storage unit storing articles and discharging the articles to a discharge port.

  Conventionally, as a discharge device provided with a mechanism for taking out articles one by one, there is, for example, one described in Patent Document 1. In the game machine described in Patent Document 1, a small capsule storage box containing a small capsule and a large capsule storage box containing a large capsule are vertically disposed, and the operator rotates the rotation lever in the right direction. Alternatively, when it is rotated leftward, capsules are discharged one by one from the small capsule storage box or the large capsule storage box corresponding to the rotation direction.

  In such a conventional game machine, a rack mechanism is used to selectively discharge capsules from a large capsule storage box or a small capsule storage box. More specifically, the large capsule storage box and the small capsule storage box are provided with large-sized and small-sized rotary disks for taking out the capsules one by one, respectively, and they are formed on the outer periphery of the rotary disk. The large and small rack plates are engaged with the gear portions, respectively. A gear portion is formed on the opposite surface of the rack plate, and the gear portion engages with the large and small spur gears, respectively. These spur gears are connected to a rotary lever.

For example, when the large-sized spur gear is rotated by the rotation lever, the spur gear meshes with the gear portion of the large-sized rack plate to move the rack plate. When the rack plate moves, the opposite gear portion of the rack plate meshes with the gear portion of the large-sized rotary disk to rotate the rotary disk, and one capsule is taken out from the large-sized capsule storage box by the rotation of the rotary disk.
On the other hand, although the small-sized spur gear connected to the rotation lever also rotates, the rack plate does not move because the spur gear slides without meshing with the gear portion of the small-sized rack plate. Here, since the gear portion of the rack plate is composed of deformable teeth, when the spur gear rotates in the direction opposite to the meshing direction with the rack plate, the spur gear is against the gear portion of the rack plate It is easy to slip and slip. Therefore, the rotational movement of the spur gear is not transmitted to the small-sized rotary disc, and the capsule is not discharged from the small-sized capsule storage box.

JP 2005-242518 A

  In the above-described conventional game machine, a rack plate is used as a mechanism for discharging the capsule, and the gear portion of the rack plate is formed of deformable teeth, so that the spur gear and the rack plate Interlocking with it is not reliable, and driving of the turntable for the capsule storage box is not reliable. Specifically, for example, when the operator vigorously turns the rotation lever and turns the spur gear quickly, the teeth of the spur gear ride over the deformable rack plate teeth, and the phase of the rack plate and the spur gear is shifted. There is a possibility of Further, for example, when the operator turns the rotary lever in one direction to a certain extent and then turns it in the opposite direction, the rack plate and the spur gear may slide and the phase of the rack plate and the spur gear may be shifted. As described above, when there is a phase shift between the rack plate and the spur gear, the operation timings of the rotary lever, the spur gear, the rack plate, and the rotary plate are shifted, and a reliable discharging operation can not be performed. In addition, once the phases of these parts shift, a phase shift occurs also at the time of the next discharging operation, and repeated discharging operations can not be performed.

In between, it can turn around the turning shaft 182.

The out-of-stock display unit 178 is a contact block 194 capable of coming into contact with the transmission unit 190 of the detection member 176 and a display block for displaying “sold out” on the product display window 16 when the product P is sold out. 196 and a communication member 198.
The contact portion 194 is formed in a substantially triangular prism, and the bottom surface can be in contact with the projection 192 of the transmission portion 190 of the detection member 176.
The display block 196 is a substantially rectangular member, and has an information display unit 200 on the upper part of the front surface on which characters such as "sold out" are printed. Guide rails 202 for guiding the movement of the display block 196 are formed on both sides and above the display block 196. The display block 196 is guided in the vertical direction by the guide rails 202, and its uppermost position is defined. Further, on the top surface of the display block 196, a protrusion 197 projecting upward is formed.

  With such a structure, when the detection member 176 is at the article detection position, the out-of-stock display unit 178 moves the display block 196 to the upper end of the guide rail 202 and information in the information display unit 200 is out-of-stock display window 16 The display block 196 moves downward and the information in the information display unit 200 is out of stock when the detection member 176 is at the article non-detection position and the article non-display position (position in FIG. 4) located above It is slidable in the vertical direction between the item display position (the position shown in FIG. 13) which can be visually recognized from the display window 16.

  The movement inhibiting member 180 has a first arm 206 and a second arm 208 pivoting about a pivot shaft 204 attached to the inner side surface of the front surface of the housing 2 as shown in FIGS. 13 and 14.

  With such a structure, the operation prohibiting member 180 is pushed up by the projection 197 of the display block 196 when the display block 196 is in the out-of-stock display position and the first arm 206 moves upward (left side in FIG. And the projection 197 of the display block 196 does not contact the first arm 206 when the display block 196 is in the out-of-stock display position, and the first arm 206 moves downward by its own weight ( In FIG. 14, it is possible to rotate between the position of the movement prohibiting member 180 on the right side and the position on the right side.

  Here, at the position where the first arm 206 has moved upward, the tip end of the second arm 208 is positioned lower than the locking portion 210 of the swing pin 162 and the swing pin 162 swings. The second arm 208 does not abut the locking portion 210. Therefore, this position of the movement inhibiting member 180 is a movement permitting position in which the second arm 208 does not block the rocking of the rocking pin 162 and the rotation of the engagement gear 160. On the other hand, when the first arm 206 is moved downward, the tip end of the second arm 208 is positioned beside the locking portion 210 of the swing pin 162, and when the swing pin 162 swings, the locking portion 210 is moved. Abut. Therefore, this position of the movement inhibiting member 180 is a movement inhibiting position where the second arm 208 prevents the swinging of the swing pin 162 and the rotation of the engagement gear 160.

[Operation of Discharge Device 1]
Next, the operation of the discharge device 1 of the present embodiment configured as described above will be described.
First, when the operator inserts a coin into the coin insertion slot 4, coins enter the coin selector 112 through the coin insertion path 110 of the coin sorter 24, and are sorted according to type. Specifically, in the present embodiment, since one 10-yen coin and one 100-yen coin are set as coins, the coin selector 112 is configured to insert a 10-yen coin or a 100-yen coin. Are sorted and sent to the coin storage unit 114. Other coins are returned to the coin return slot 12.

  When a predetermined number of coins of a predetermined type are stored in the coin storage unit 114, the rotation board 124 of the operation control mechanism 26 is permitted to rotate, and the rotation board 124 can be rotated clockwise in FIG. The operator rotates the handle 6 rightward by selecting whether to rotate the handle 6 rightward (clockwise as viewed from the front) or leftward (counterclockwise as viewed from the front) to store the first article. It is selected whether to take out the article P from the unit 34 or to turn it leftward to take out the article P from the second article storage unit 36. Hereinafter, the case where the operator turns the handle 6 in the right direction will be described.

FIG. 15 is a view showing the operation of the cooperation mechanism 28 of the discharge device 1 according to the present embodiment. When the operator rotates the handle 6 to the right, the rotation shaft 132 also rotates. Along with this rotation, the fixed cylindrical portion 140A of the first ratchet mechanism 134A and the fixed cylindrical portion 140B of the second ratchet mechanism 134B also rotate. Since the fixed cylindrical portions 140A and 140B and the transmission cylindrical portions 142A and 142B are engaged with each other by the recessed portions 150A and 150B and the protruding portions 154A and 154B, respectively, the transmission cylindrical portions 142A and 142B are also rotated in the same direction, that is, rightward. Do.
The transmission barrel portion side ratchet portion 152A of the transmission barrel portion 142A of the first ratchet mechanism 134A engages with the bevel gear side ratchet portion 146A when the transmission barrel portion 142A rotates in the right direction, so the transmission barrel When the portion 142A rotates, this rotation is transmitted to the bevel gear 138A, and the bevel gear 138A rotates to the right. Due to the rotation of the bevel gear 138A, the bevel gear 130 fixed to the rotary disc 124 of the operation control mechanism 26 rotates rightward when the bevel gear 130 is viewed from the axial direction (the state of FIG. 10).

  In the second ratchet mechanism 134B, the bevel gear 138B rotates leftward (counterclockwise) when viewed from the front of the housing 2 by the rotation of the bevel gear 130. On the other hand, the transmission cylindrical portion 142B of the second ratchet mechanism 134B rotates rightward as described above. Here, since the transmission cylinder part side ratchet part 152B does not engage with the bevel gear side ratchet part 146B when the transmission cylinder part 142B rotates in the right direction, the transmission cylinder part 142B rotates in the right direction. When the bevel gear 138B rotates in the left direction, the transmission barrel portion side ratchet portion 152B and the bevel gear side ratchet portion 146B slide without engaging with each other. At this time, the transmission cylinder side ratchet part 152B is pushed by the inclined surface of the bevel gear side ratchet part 146B, and the transmission cylinder 142B moves to the rear of the housing against the biasing force of the spring 158B. Although the transfer cylinder 142B approaches the fixed cylinder 140B by this movement of the transmission cylinder 142B, the gap between the recess 150B of the fixed cylinder 140B and the projection 154B of the transmission cylinder 142B and the protrusion of the fixed cylinder 140B Since a gap G of a predetermined size is formed between the portion 148B and the recess 156B of the transmission cylinder 142B, the movement of the transmission cylinder 142B is absorbed by the gap G, and the transmission cylinder 142B is a fixed cylinder. It does not abut on the portion 140B.

  When the handle 6 is rotated in the reverse direction, that is, in the left direction (counterclockwise) when viewed from the front, the rotation shaft 132 rotates in the left direction, and the fixed cylindrical portions 140A and 140B and the transmission cylindrical portion 142A, Each 142B rotates in the left direction. Since the transmission cylinder side ratchet portion 152B and the bevel gear side ratchet portion 146B of the second ratchet mechanism 134B mesh with each other, the bevel gear 138B rotates in the left direction. This rotation of the bevel gear 138B causes the bevel gear 130 to rotate to the right when the bevel gear 130 is viewed from the axial direction (the state of FIG. 10). The bevel gear 138A of the first ratchet mechanism 134A rotates rightward and slips with the transmission cylinder 142A.

  In short, regardless of whether the steering wheel 6, that is, the rotary shaft 132 is rotated leftward or rightward, the bevel gear 130 fixed to the rotary disc 124 of the operation control mechanism 26 has the bevel gear 130 seen from the axial direction (The state of FIG. 10) rotates in the right direction. Therefore, in the present embodiment, the linkage mechanism 28 converts both rightward (clockwise) or leftward (counterclockwise) rotation of the handle 6 as viewed from the front into one-direction rotation in the bevel gear 130. Functions as a rotation direction conversion mechanism.

  When the bevel gear 130A is rotated by the bevel gear 138A of the first ratchet mechanism 134A, and the rotation plate 124 is rotated by this rotation, a step (not shown) formed on the outer periphery of the rotation plate 124 pushes the coin support bar 119. As a result, the coin support bar 119 pivots to open the bottom surface of the coin guiding path, and the coin stored in the coin guiding path falls into the coin storage unit 14.

FIG. 16 is a view showing the operation of the rotation prevention mechanism 30 of the discharge device 1 according to the present embodiment. As shown in FIG. 16, in the rotation preventing mechanism 30, when the operator rotates the handle 6 clockwise as viewed from the front, the rotary shaft 132 rotates clockwise and the engagement gear 160 fixed to this also rotates clockwise. . In FIG. 16, since the rotation preventing mechanism 30 is viewed from the rear of the housing 2, the engagement gear 160 is shown turned leftward.
When the engagement gear 10 rotates rightward from the initial position where the engagement portion 172 of the swing pin 162 engages with the initial position recess 166 of the engagement gear 160, the initial position teeth 165 push the swing pin and the swing pin Reference numeral 162 swings to the right (left in FIG. 16) about the swing shaft 162A. When the engaging portion 172 gets over the initial position teeth 165 and reaches the position of the first engaging recess 163, the engaging portion 172 engages with the first engaging recess 163, as shown in FIG. In this state, when trying to rotate the engagement gear 160 to the opposite side, that is, to the left (right side in FIG. 16), the engagement portion 172 abuts on the first engagement recess 163, and rotation of the engagement gear 160 in the opposite direction To stop. Similarly, when the engaging gear 172 is rotated in the opposite direction even when the engaging portion 172 is engaged with the second engaging recess 168 or the third engaging recess 170, the second engaging portion 172 It strikes the engagement recess 168 or the third engagement recess 170 and prevents the rotation of the engagement gear 160 in the opposite direction.
Therefore, in the present embodiment, when the engagement gear 160 is rotated to a position where the engagement portion 172 is rotated by a predetermined angle engaged with the first engagement recess 163, rotation of the engagement gear 160 in the opposite direction thereafter is performed. Is prohibited.

Next, the operation of the drive mechanism 22 will be described.
17, 18, 20 and 22 are diagrams showing the operation of the drive mechanism 22 of the discharge device 1 according to this embodiment, and FIG. 19 is an enlarged sectional view along the line XIX-XIX in FIG. 21 is an enlarged sectional view taken along the line XXI-XXI of FIG. 20, and FIG. 23 is an enlarged sectional view taken along the line XXIII-XXIII of FIG.
When the operator rotates the steering wheel 6 in the right direction, the drive wheel 84 of the drive mechanism 22 also rotates in the right direction from the initial position of FIG. As shown in FIG. 17, the engagement pin 92 of the drive wheel 84 reaches the slot 98 of the right driven wheel 86. From the initial position to the position shown in FIG. 17, the arc surface 96 of the restriction plate 95 of the drive wheel 84 faces the arc surface 100 of the right driven wheel 86, so the right driven wheel 86 does not rotate, It maintains its initial position.

Thereafter, when the drive wheel 84 is further rotated, as shown in FIG. 18, the engagement pin 92 engages with the slot 98, and the drive wheel 84 rotates the right driven wheel 86. When the drive wheel 84 further rotates and the engagement between the engagement pin 92 and the slot 98 is released as shown in FIG. 20 and FIG. 22, the arc surface 100 of the right driven wheel 86 is again the arc surface 96 of the drive wheel 84. , And the rotation of the right driven wheel 86 is stopped, and the position of the driven wheel 86 is maintained.
Therefore, in the present embodiment, the continuous rotational motion of the drive wheel 84 is converted to the intermittent rotational motion of the driven wheel 86 by the Geneva mechanism including the drive wheel 84 and the driven wheel 86.

On the other hand, in the driven wheel 86 on the left side, when the drive wheel 84 rotates from the initial position of FIG. 7 to the position shown in FIG. 17, the arc surface 96 of the drive wheel 84 faces the arc surface 100 of the driven wheel 86 on the left. Therefore, the left driven wheel 86 does not rotate and remains at the initial position.
When the drive wheel 84 further rotates and the engagement pin 92 reaches the slot 98 of the left driven wheel 86 as shown in FIG. 18, the engagement pin 92 passes through the notch 104 of the slot 98 to the wall 102. And enter under the driven wheel 86 as shown in FIG. Therefore, the left driven wheel 86 does not rotate during this time.

When the drive wheel 84 further rotates, the engagement pin 92 of the drive wheel 84 reaches the guide surface 106 of the left driven wheel 86, as shown in FIGS. The engagement pin 92 is pushed by the guide surface 106, and moves from the protruded position to the retracted position as shown in FIG. Thereafter, when the drive wheel 84 is further rotated, as shown in FIG. 22, the engagement pin 92 is disengaged from the guide surface 106 and moves to the outside of the driven wheel 86. The engagement pin 92 moves from the retracted position to the projecting position as shown in FIG. 23 by the biasing force of the spring 93.
As a result, while the drive wheel 84 rotates, the left driven wheel 86 does not rotate, and the initial position is maintained.

  As described above, when the drive wheel 84 makes one rotation to the right, the three engagement pins 92 intermittently rotate the driven wheel 86 on the right side, and the driven wheel 86 makes a half rotation. The rotation of the driven wheel 86 is transmitted to the rotation shaft 80 of the takeout mechanism 20 via the first transmission wheel 88 and the second transmission wheel 90.

  24 and 25 are diagrams showing the operation of the takeout mechanism 20 of the discharge device 1 according to the present embodiment. When the rotation shaft 80 of the take-out mechanism 20 is rotated by the drive of the drive mechanism 22, the engagement wheel 78 fixed to the rotation shaft 80 is seen from the front of the housing 2 from the initial position shown in FIG. Rotate (counterclockwise). When the engaging wheel 78 rotates, the engaging teeth 82 of the engaging wheel 78 engage with the teeth 76 of the article removing member 52, and pushes the article removing member 52 toward the left side (the inside of the housing). The article takeout member 52 moves to the left against the urging force of the spring 74, and the pushing portion 58 pushes the side of the lowermost one of the plurality of articles P stacked in the article storage box 36A. The article P is moved by one to the left.

  At this time, as shown in FIG. 24, the upper surface of the extrusion unit 58 contacts the bottom surface of the next article P stored in the article storage box 36A to support the bottom surface. The projections 71 formed on the upper surface of the pushing portion 58 reduce the friction between the pushing portion 58 and the next article P. Further, since the flap 46 of the article storage box 36A is biased toward the storage position by the spring 47 (FIG. 4), the flap 46 pushes the article P to the right when the article P is pushed to the left by the pushing portion 58. The product P is pressed against the extrusion unit 58 and brought into contact with it.

  When the engagement wheel 78 is further rotated and the third engagement tooth 82 of the engagement wheel 78 is engaged with the tooth 76 of the article removal member 52, as shown in FIG. Move to the left eject position. In this position, a part of the article P protrudes from the article storage box 36A, and the article P is moved to the left relative to the bottom surface portion 40 and the rail 66. Further, the article P pushes up the flap 46 and rotates the flap 46 to the projecting position.

When the engaging wheel 78 further rotates, as shown in FIG. 25, the engagement tooth 82 of the engaging wheel 78 and the tooth 76 of the article taking out member 52 disengage from each other, and the article taking out member 52 Return to the initial position by the biasing force of. At this time, the projections 68 formed on the upper surface of the article support portion 56 of the article removal member 52 reduce the friction between the article support portion 56 and the article P. The article takeout member 52 moves from the initial position to the takeoff position by the engagement between the engagement wheel 78 and the teeth 76, and moves from the takeoff position to the initial position by biasing of the spring 74. The moving speed of 52 is faster when moving from the removal position to the initial position than when moving from the initial position to the removal position.
The article P remains in the position while the article takeout member 52 returns to the initial position. The article P is not supported by the article takeout member 52 from the lower side, falls down from the outlet 44 by its own weight and by the force of the flap 46 and the weight of the article P stacked thereon, and falls on the slope 33 Move to the outlet 8 side. The operator can take out the article P from the outlet 8.

Here, in one cycle of the taking-out operation in which the article taking-out member 52 moves from the state of FIG. 6 to the state of FIG. 25, the rotating shaft 80 and the engagement wheel 78 make a half rotation. At this time, since the engaging car 78 of the front article storage box 36A and the engaging car 78 of the rear article storage box 36B are 180 ° out of phase with each other, one engaging car 78 is at the position shown in FIG. , The other engagement wheel 78 is in the position of FIG. Therefore, in the next cycle, the engagement wheel 78 of the other item storage box 36B moves the item removal member 52, and removes the item P.
Thus, the takeout mechanism 20 takes out the articles P alternately from the front and rear article storage boxes 36A, 36B.

When the article P is stored in the front article storage box 36A, the detection member 176 of the stock removal mechanism 32 is pushed from above by the article P, and the upper surface 184A of the detection portion 184 of the detection member 176 is the article storage box. It is located at an article detection position as shown in FIG. 4 aligned with the bottom 40 of 36A. At this time, the transmission portion 190 of the detection member 176 abuts on the contact portion 194 of the stock out display portion 178 and pushes up the dead end display portion 178 against its own weight. The display block 196 of the out-of-stock display portion 178 moves upward along the guide rail 202 and abuts on the upper end of the guide rail 202 to stop. In this position, the display of the characters such as "sold out" on the information display unit 200 of the display block 196 can not be seen from the out-of-stock display window 16.
Further, the first arm 206 of the movement inhibiting member 180 is positioned upward as shown on the left side in FIG. 14, and the tip of the second arm 208 is lower than the locking portion 210 of the swing pin 162 of the rotation preventing mechanism 30. The rocking pin 162 can be rocked to the right as viewed from the front of the housing 2. Therefore, the engagement gear 160 can be rotated to the right, that is, the operator can rotate the handle 6 to the right.

  When the article removal member 52 moves from the initial position toward the removal position with the detection member 176 of the article removal mechanism 32 at the article detection position, as shown in FIG. It emerges from the bottom 40 and engages the slit 186 of the detection member 176. Thereby, the detection member 176 is maintained at the article detection position while the article P is moving toward the left side.

  On the other hand, when the articles P stored in the article storage box 36A are exhausted, the detection member 176 is pivoted about the pivot shaft 182 by its own weight of the out-of-stock display portion 178, as shown in FIG. The position 184 is positioned at the article non-detection position projecting above the bottom surface 40. As a result, since the transmission portion 190 of the detection member 176 is lowered, the out-of-stock display unit 178 is lowered by its own weight while being guided by the guide rail 202 and positioned at the out-of-stock display position. At this position, information such as the letters “sold out” in the information display unit 200 of the display block 196 can be seen from the stockout display window 16, and the operator can see the second article storage unit on the right side of the housing 2. It can be seen that the article P stored in 36 is out of stock.

  When the detection member 176 of the stock removal mechanism 32 is in the article non-detection position, the first arm 206 of the movement inhibition member 180 is in the position as shown on the right in FIG. At this time, since the first arm 206 is not pushed up by the display block 196, the first arm 206 is lowered, thereby pivoting the second arm 208 upward. The tip of the second arm 208 is disposed at a position to abut on the locking portion 210 of the swing pin 162. Therefore, when the swing pin 162 tries to swing to the right as viewed from the front of the housing 2, it can not swing against the second arm 208. For this reason, since the engagement gear 160 can not also rotate in the right direction, the operator can not rotate the handle 6 in the right direction.

According to the embodiment configured as described above, the following excellent effects can be obtained.
The drive mechanism 22 comprises a geneva mechanism including a drive wheel 84 with an engagement pin 92 and a driven wheel 86 with a slot 98 for engaging the engagement pin 92 so that the mechanism is engaged. The pin 92 and the slot 98 are positively engaged so that the drive wheel 84 reliably rotates the driven wheel 86. According to such a Geneva mechanism, as the rack mechanism employed in the discharge function of the conventional game machine does not shift in phase with each other, the phase or operation timing of each mechanism of the discharge device 1 shifts. Can be performed repeatedly and reliably.

  Further, since the drive mechanism 22 includes the Geneva mechanism using the drive wheel 84 and the driven wheel 86, the rotational movement of the handle 6 can be transmitted to the takeout mechanism 20 as a rotational movement. Here, in the discharge mechanism using the conventional rack mechanism, since the rack plate must be arranged to linearly move in a predetermined direction, the degree of freedom in the layout of the mechanism is low, and the required length of the rack plate and Since the moving space must be secured, the discharge mechanism becomes large. On the other hand, in the present embodiment, the drive mechanism 22 uses a Geneva mechanism using the drive wheel 84 and the driven wheel 86, and the drive force can be transmitted by rotational movement. The first transmission wheel 88 and the 21st transmission wheel 90 can be arranged more freely than in the prior art. Further, since the drive mechanism 84 includes the drive wheel 84 and the driven wheel 86, the space saving of the drive mechanism 22 can be achieved as compared with the discharge mechanism by the conventional rack mechanism.

  The first article storage unit 34 and the second article storage unit 36, and the takeout mechanism 20 provided in each of the first article storage unit 34 and the second article storage unit 36, and the drive mechanism 22 has a rotational direction of the handle 6 Since either of the takeout mechanisms 20 is selectively driven according to the first article storage unit 34 and the second article storage unit 36, different types of articles, for example, articles of different shapes and tastes are stored. The operator can select the goods to be discharged by selecting whether the handle 6 is turned to the right or to the left.

The right driven wheel 86 of the drive mechanism 22 causes the engagement pin 92 of the drive wheel 84 to engage the slot 98 of the driven wheel 86 to rotate the driven wheel 86 when the drive wheel 84 rotates in the right direction. When the car 84 rotates leftward, the engagement pin 92 does not engage the slot 98 of the driven car 86 and the driven car 86 does not rotate. On the other hand, in the driven wheel 86 on the left side, when the driving wheel 84 rotates in the left direction, the engagement pin 92 of the driving wheel 84 engages with the slot 98 of the driven wheel 86 to rotate the driven wheel 86. Rotates clockwise, the engagement pin 92 does not engage the slot 98 of the driven wheel 86 and the driven wheel 86 does not rotate.
With such a structure of the drive mechanism 22, it is possible to easily select which of the right and left takeout mechanisms 20 is to be driven by selecting the direction in which the drive wheel 84 is to be rotated.

Since the engagement pin 92 of the drive wheel 84 is movable between the projecting position and the retracted position, when the driven wheel 86 does not rotate due to the rotation of the drive wheel 84, the engagement pin 92 moves to the retracted position. Thus, the engagement pin 92 does not engage with the slot 98. Therefore, it is possible to ensure that rotational motion is not transmitted from drive wheel 84 to driven wheel 86 with a simple structure.
Further, since the notch 104 and the guide surface 106 are formed in the driven wheel 86, the engagement pin 92 is guided from the projecting position to the retracted position only by rotating the driving wheel 84 with respect to the driven wheel 86. Therefore, the movement between the projecting position and the retracted position of the engagement pin 92 can be realized without requiring a complicated structure.

  Since the rotation prevention mechanism 30 is provided, when the operator rotates the handle 6 by a predetermined angle or more, the handle 6 can not be rotated in the opposite direction. Therefore, it is possible to prevent the operator from repeatedly rotating the handle 6 in the right direction or the left direction, and it is possible to prevent an operation failure or a failure that may occur.

  Since the rotation prevention mechanism 30 has the swing pin 162 and the engagement gear 160, when the engagement gear 160 rotates with the rotation of the handle 6, the swing pin 162 swings to engage the engagement gear 160. The engagement recess 164 is engaged to prevent the reverse rotation of the engagement gear 160. Therefore, the reverse rotation of the handle 6 can be prevented with a simple structure.

  Since the ejection device 1 includes the coin sorting device 24 and the operation control mechanism 26 that permits the drive mechanism 22 to be driven only when a predetermined number of coins of a predetermined type is inserted, the ejection device 1 is Can also be used as a sales apparatus for selling the article P for the amount of money.

  The motion control mechanism 26 has a rotary disc 124 that rotates only in one direction (clockwise) in the right direction when viewed from the axial direction, and the linkage mechanism 28 rotates the steering wheel 6 and hence the drive wheel 84 in the right direction. And both left-handed rotations are converted to one-way rotation of the turntable 124. Therefore, the cooperation mechanism 28 can coordinate the movement of the handle 6 in both directions and the movement of the movement control mechanism 26 in one direction.

  The takeout mechanism 20 has an article takeout member 52 for placing an article P to be taken out, and the article takeout member 52 has an initial position for holding the article P in the article storage unit 34, 36; As it is movably provided between the take-out position to be moved to the take-out port 44 of 34, 36, only one article P is placed and moved to the take-out port 44 while maintaining a stable posture. Can. Thereby, the article P can be reliably transported to the outlet 44.

  Also, at this time, the article removal member 52 is moved from the initial position to the removal position by the removal member drive mechanism 54, while the article removal member 52 is biased toward the initial position by the spring 74. When the member 52 returns from the removal position to the initial position, it moves faster than the speed for moving from the initial position to the removal position. Thereby, the article removing member 52 can be returned to the initial position while leaving the article P placed on the article removing member 52 at the outlet 44, and the article P is reliably discharged from the outlet 44 to the slope 33. be able to.

  Furthermore, since the extrusion part 58 is provided in the article removal member 52, while the article removal member 52 extrudes one article P, the upper surface of the extrusion part 58 supports the bottom surface of the next article P. Therefore, the article P stored in the article storage unit 34, 36 can be stably supported even during the removal operation of the article P.

Since the discharge device 1 is provided with the stock out mechanism 32, when the first article storage unit 34 or the second article storage unit 36 runs out of articles P, information such as "sold out" is displayed in the out-of-stock display window 16 can do. Therefore, the operator can recognize that the item P is out of stock.
Further, since the item cutting mechanism 32 has the operation prohibiting member 180, when the article P disappears in the first article storage part 34 or the second article storage part 36, the movement inhibiting member 180 stores the article P. The rotation of the handle 6 in the direction corresponding to the portions 34, 36 can be prohibited. Thus, it is possible to prevent the drive mechanism 22 and the takeout mechanism 20 from operating due to the rotation of the handle 6 in spite of the shortage of the articles P, and the articles P are not discharged even though the handle 6 is operated. You can avoid the situation.

However, in the present invention, only the first article or only the second article may be stored. The first article and the second article may be mixed and stored. Further, only the first article may be stored in the first article storage section 34 and the second article storage section 36, or the first article storage section 34 and the second article storage section 36 may have different shapes, ie, the first The first article or the second article having the same shape as the first article storage unit 34 and the second article storage unit 36 but may have different tastes. You may store each. Thus, the first article storage unit 34 and the second article storage unit 36 can store any item according to the desired specification.
