The game is competed by no.
JP 2004-16650 A Japanese Patent Laid-Open No. 11-76503

  The packs and medals used in such a game machine are collected from one place by a transport device provided inside the game machine after dropping from the game board surface or belt, and also used for the next game. It is conveyed to. In many cases, packs and medals must be arranged and transported one by one in such a transport path. Also, when handling not only game media such as packs and medals, but also coins etc., coins must be aligned and transported one by one, or dispensers etc. need to be taken out from the stored coins one by one. .

  Thus, when handling disc-shaped workpieces such as medals, packs, and coins, it is often necessary to separate one by one from a plurality of collected or collected discs. In such a case, a disk feeding device using a cylindrical case is easily used. A circular plate is supplied to the tube case in an irregular posture from a hopper tank or a conveyor belt. At this time, the inner diameter of the cylindrical case is made somewhat larger than the diameter of the circular plate so that the circular plate is not clogged inside the cylindrical case, and the circular plates are accommodated therein in a vertical row. The whole disk stacked in the cylinder case is supported by a receiving plate provided under the cylindrical case, but between the opening at the lower end of the cylindrical case and the receiving plate, one or more disks and less than two disks A gap is formed. Then, by moving an extruded plate having a thickness of not more than one disk so as to cross this gap, only one bottom layer disk in contact with the receiving plate can be discharged out of the cylindrical case. .

  By the way, as mentioned above, the delivery device generally has a hopper tank having a funnel-shaped lower side above the cylinder case, and the disc recovered by the conveyor belt is disposed from the outlet of the hopper tank to the cylinder case. It is dropped in sequentially. When the disks supplied to the cylinder case are stored in an orderly stacked manner in the cylinder case, the disks can be accurately discharged one by one for each reciprocating movement of the extrusion plate. However, when the disc is dropped into the cylindrical case, the disc is not necessarily in a horizontal posture and often falls into the cylindrical case in an inclined posture.

  Since the inner diameter of the cylinder case is larger than the diameter of the disk as described above, most disks can be received in a horizontal position on the receiving plate or the disk already contained in the cylinder case. However, when the disc enters the cylinder case with a large inclination, the lower edge is received by the backing plate in that posture, and the subsequent disc is supplied before this disc settles in the horizontal posture. If it comes, the following disk may be stacked on the disk that is tilted. Then, as shown in FIG. 9A, the discharge operation by the push-out plate 12 is started while the lower edge of the inclined disc 8 is in contact with the receiving plate 11.

  At this time, if the center 8 a of the disk 8 is on the center axis 13 a of the cylindrical tube case 13, the disk 8 easily returns to the horizontal posture, but the inner diameter of the tube case 13 with respect to the diameter of the disk 8 is Since it is enlarged, the center 8a of the disk 8 may be shifted to the left side to some extent as shown in the figure. Then, even though the inner diameter of the opening edge 13b formed at the lower end of the cylindrical case 13 is larger than the diameter of the disk 8, the outer peripheral edge of the disk 8 protruding below the opening edge 13b. Is caught on the opening edge 13b from the lower side, and the disk 8 does not return from the inclined posture even if a load is applied by another disk stacked above the opening edge 13b.

  When the disk discharging operation is started in this state, the pushing plate 12 slides leftward by driving the motor and pushes the lower end side of the disk 8 leftward as shown in FIG. 9B. As a result, the disk 8 tries to rotate in the clockwise direction, but a biting occurs between the outer peripheral edge of the disk 8 and the opening edge 13b, and the pushing plate 12 is prevented from moving in the left direction. This phenomenon is likely to occur as the center 8a of the disc 8 that has fallen while being tilted deviates from the central axis 13a of the cylindrical case 13. The biting between the two is difficult to eliminate even if the driving force of the push-out plate 12 is increased, and as a result, the discharge becomes impossible.

  In addition, medals and packs for game consoles, and even coins, often have dust attached to them, and such dust can easily fall and accumulate on the backing plate during long use. . The backing plate also serves as a sliding surface for discharging the disc.If foreign matter accumulates on the surface of the backing plate, it may cause an excessive load when the disc is discharged, hindering smooth feeding. There is a risk of it coming.

  The present invention has been made in consideration of the above circumstances, and when the extrusion plate is reciprocated at the lower end of the cylindrical case to discharge the discs one by one, the circular plate is moved in the cylindrical case or in the movement path of the extrusion plate. An object of the present invention is to provide a disk feeding device that prevents clogging.

  In order to achieve the above object, the present invention comprises a cylindrical case for stacking and accommodating circular plates in a vertical row, and a receiving plate for receiving the lowermost circular plate and receiving the circular plate in the cylindrical case. A gap that is larger than the thickness of one disc and smaller than the thickness of two discs is formed between the plate and the backing plate, and moves along the backing plate within this gap, and the thickness of the extrusion edge is reduced to a circle. An improvement is made to the disk feeding device that pushes out the pushing member that is equal to or less than one plate and pushes the lowermost disk out of the cylindrical case. The reason is that a circular opening which is substantially coincident with the central axis and whose inner diameter is smaller than the diameter of the disk is formed.

  The inner diameter of the opening formed in the backing plate is preferably 50% to 95% of the diameter of the disc. In order to correct the disc stored in the tilted posture into a horizontal posture by moving the pushing member, it is more effective to increase the size of the opening to some extent, preferably 60% or more and 95% or less, Preferably it is 75% or more and 95% or less. If the inner diameter of the opening is made larger than 95% of the diameter of the disk, especially when the inner diameter of the cylindrical case is made larger than the diameter of the disk, the disk that would normally be in a horizontal position on the receiving plate is one of them. Since the part protrudes from the opening and the posture of the disk tends to tilt, it is not preferable.

  Further, it is preferable that the pushing member is constituted by a pushing plate having a width substantially equal to the diameter of the disk and elongated in the moving direction, and its pushing edge is formed in a concave shape matching the shape of the outer peripheral surface of the disk. It is possible to link the disk with manual operation such as lever operation, but it is easy to use an actuator such as a motor, and the passage of the disk discharged from the cylindrical case is detected. If a discharge sensor is provided, it is possible to reliably detect the discharge of the disks one by one. When an actuator is used for feeding, it is preferable to drive the extrusion plate every cycle. During this cycle, the push-out plate moves from a standby position where it waits outside the cylinder case to a discharge position where the disk is pushed out of the cylinder case, and operates to return to the standby position again. A first sensor for detecting that the push plate has moved from the standby position to the discharge position and the push plate returned from the discharge position to the standby position so that such an operation can be easily performed using a DC motor. The second sensor for detecting this can be used effectively. Further, by using the discharge sensor and the first and second sensors, it is possible to automatically re-activate the disk when the disk is not delivered by one stroke of the extrusion plate.

  Since the receiving plate has a relatively large opening of 50% or more and 95% or less of the diameter of the disc immediately below the cylindrical case, the circular plate is supplied into the cylindrical case with foreign matters such as dust attached thereto. Even if the foreign matter falls in the cylinder case, most of it is discharged to the outside from the opening, and even if it temporarily stays on the receiving plate, it is not removed from the opening while the disk is being sent out by the pushing member. Since it falls, dust and the like do not accumulate on the receiving plate, and there is no hindrance to the feeding of the disc. Further, the opening formed in the receiving plate is arranged so that when the disc is inclined and dropped into the cylindrical case, the disc is placed in the center direction of the cylindrical case while the edge of the opening is in sliding contact with the lower outer edge of the disc. The center of the disc is not extremely separated from the center of the cylindrical case. Therefore, when the push-out member is moved, the disk is easy to rotate at that position, and the tilted disk can be easily corrected to a horizontal posture.

  If the extruding member is a plate-like extruding plate and its extruding edge has a concave shape that matches the shape of the disc, the extruding plate can be moved even if the disc tilts around the central axis of the cylinder case. The posture of the disc can be corrected without inconvenience. By providing a discharge sensor that detects the passage of the disk when the disk is discharged from the cylinder case by the push-out plate, it is possible to count the disks sent from the cylinder case. Furthermore, when the push plate is configured to be driven by an actuator such as a motor, the first and second sensors are defined as one cycle from when the push plate is moved from the standby position to the discharge position and then back to the standby position. In addition to detecting the position of the extrusion plate at each of the standby position and the discharge position, and also monitoring the discharge signal from the discharge sensor, the disk was not delivered in one stroke of the extrusion plate. Sometimes, the extrusion plate can be automatically re-actuated to carry out the disk feeding.

  In FIG. 1 which shows the outline of the pack delivery apparatus of an air hockey game machine, the disk-shaped pack which fell from the game board surface of the game machine is collect | recovered by the hopper tank 20 by conveyance means, such as a belt. A pack delivery device 22 using the present invention is provided below the hopper tank 20, and the packs 10 dropped from the hopper tank 20 are accommodated in the cylindrical tube case 24 in a horizontal posture and stacked in a vertical row. Is done. The pack 10 has a diameter of about 83 mm and a thickness of about 8 mm, and the cylindrical case 24 has an inner diameter of about 97 mm. The pack delivery device 22 sends out the packs 10 accommodated in the cylindrical case 24 one by one from the lowest layer. The pack delivery device 22 can deliver about 80 packs per minute during continuous operation. The delivered pack 10 is further sent to the pack elevator 26 by the transport belt 25, and the pack elevator 26 is sent to, for example, a launching device in order to use the pack 10 for a game.

  As shown in an exploded view in FIG. 2, the pack delivery device 22 has an elongated rectangular receiving plate 27 fixed to a required portion inside the game machine with screws, and covers the upper surface of the receiving plate 27. The cover plates 30 and 31 are screwed across the spacers 28 on both side edges. The thickness of the spacer 28 is about 9 mm, for example, and is slightly larger than the thickness of one pack 10. The above-described cylinder case 24 and the discharge sensor 33 are fixed to the cover plate 30. The discharge sensor 33 is configured by a micro switch, and is turned on while the pack 10 discharged from the cylinder case 24 passes through the receiving plate 27.

  The cover plate 31 covers an extrusion plate 35 serving as a pack extrusion member. The thickness of the extrusion plate 35 is slightly smaller than the thickness of the spacer 28, and when the cover plate 31 is screwed to the receiving plate 27, the extrusion plate 35 is moved upward by horizontal bent portions formed on both side edges of the cover plate 31. Movement is restricted. Therefore, the pushing plate 35 slides in the direction of the arrow X while sliding on the upper surface of the receiving plate 27, and hardly moves upward.

  In order to move the extrusion plate 35 in the arrow X direction, it is possible to detect that the rack 36 having a tooth row along the movement direction is fixed and that the extrusion plate 35 has moved to the standby position and the discharge position. In addition, a tongue-shaped first signal piece 37 and a second signal piece 38 are fixed to the extrusion plate 35. A gear box 40 is fixed to the upper surface of the cover plate 31, and a motor 41 and a transmission gear system are incorporated in the gear box 40, and the transmission gear system appropriately reduces the rotation of the motor 41 and transmits it to the pinion 42. . The pinion 42 is meshed with the rack 36, so that the pusher plate 35 moves in the direction of the arrow X by the rotation of the motor 41.

  The first sensor 45 and the second sensor 46 made of a photo interrupter are fixed to the cover plate 31, and the photoelectric detection that the first signal piece 37 and the second signal piece 38 described above have moved inside the cover plate 31. To do. On the left end side of the push-out plate 35, a push-out edge 35a having a semicircular arc-like concave shape is formed in accordance with the outer peripheral surface of the pack 10. When the push plate 35 moves to the discharge position indicated by the two-dot chain line in the figure by the normal rotation of the motor 41, the first sensor 45 detects the first signal piece 37 and turns on. Further, when the motor 41 rotates in the reverse direction and the push-out plate 35 returns from the discharge position to the illustrated standby position, the second sensor 46 detects the second signal piece 38 and turns on.

  In order to supply the pack 10 accommodated in the cylindrical case 24 onto the receiving plate 27, the cover plate 30 has an opening 30a having the same diameter as or slightly larger than the inner diameter of the cylindrical case 24 (see FIG. 3A). Is formed, and the lowermost pack 10 is supported on the upper surface of the receiving plate 27 as indicated by a two-dot chain line in the figure. The pack 10 supported here is pushed by the pushing edge 35a when the pushing plate 35 moves in the discharging direction, passes through a moving path formed between the cover plate 30 and the receiving plate 27, and is pushed out by the pushing plate. Just before 35 moves to the discharge position, it falls from the receiving plate 35.

  Since both side edges of the cover plate 30 are lowered by about the plate thickness as shown in the figure, the gap between the cover plate 30 and the receiving plate 27 is larger than the thickness of the spacer 28. This is to reduce the load when the pack 10 is discharged as much as possible, and this gap does not reach the thickness of two packs 10. The thickness of the extrusion edge 35a of the extrusion plate 35 is less than the thickness of one pack so that only the lowermost pack 10 is extruded. If the thickness of the portion that enters directly below the cylindrical case 24 when the extrusion plate 35 reaches the discharge position is less than the thickness of one pack, for example, the rack 36 and the signal pieces 37 and 38 are fixed. The thickness of the portion may be made larger than the thickness of one pack together with the thickness of the spacer 28.

  A circular opening 48 is formed in the receiving plate 27 at a portion that supports the lowermost pack 10. The center of the opening 48 substantially coincides with the central axis of the cylindrical case 24, and its inner diameter is 65 mm. The inner diameter of the opening 48 is determined in consideration of the diameter of the pack 10, and may be in the range of 50% to 90% with respect to the diameter of the pack 10, preferably 60% to 90%, more preferably 75% to 90%. % Range. When the foreign matter such as dust enters the cylinder case 24 together with the pack 10, the opening 48 acts to discharge the foreign matter to the outside of the plate 27, and the posture in which the pack 10 is inclined as described in detail later. Even if it enters the cylinder case 24 as it is, it acts to make it easier to correct it into a horizontal posture.

  A control circuit board 49 is fixed to one side surface of the cover plate 31, and signal lines from the discharge sensor 33, the motor 41, the first and second sensors 45, 46 are connected via a connector. The control circuit board 49 responds to an input of a pack delivery command from the outside, and monitors the signals from the discharge sensor 33 and the first and second sensors 45 and 46, for example, according to the sequence shown in FIG. Control the drive. The control circuit board 49 does not necessarily have to be fixed to the side surface of the cover plate 31, and can be provided at an arbitrary position away from the bottom surface of the receiving plate 27 and the pack delivery device 22.

  Here, with reference to FIGS. 3-6, the attitude | position correction effect | action of the pack 10 by the extrusion plate 35 and the opening 48 is demonstrated. FIG. 3 is a schematic cross-section when viewed from the discharge direction of the pack 10, and the movement direction of the extrusion plate 35 is a direction perpendicular to the paper surface. If the pack 10 is dropped into the cylinder case 24 with the upright posture, the lower end of the pack 10 protrudes from the opening end 24b of the cylinder case 24 and further enters the opening 48 of the receiving plate 27. Although the pack 10 is about to fall further downward, the pack 10 is guided so that its center 10 a approaches the center axis 24 a of the cylindrical case 24 while the outer peripheral edge of the pack 10 rubs against the opening edge of the opening 48. In the guide plate having no opening 48, the position of the pack 10 is determined by the difference between the inner diameter of the cylindrical case 24 and the diameter of the pack 10 in the horizontal direction with respect to the paper surface, as shown by a two-dot chain line in FIG. In contrast, when the receiving plate 27 provided with the opening 48 is used, it appears completely in common regardless of the direction in which the pack 10 is rotated about the central axis 24a.

  Since the inner diameter of the opening 48 is smaller than the diameter of the pack 10, the pack 10 stops at the position shown by the solid line in FIG. The pack 10 falls in either direction, but the diameter of the pack 10 is larger than the inner diameter of the opening 48, so that there is no biting between the two, and in most cases the pack 10 is horizontally below the cylinder case 24. I will fall to the posture. If the inner diameter D of the opening edge 24b (equal to the inner diameter of the cylinder case 24) is made too large relative to the diameter of the pack 10, the pack 10 can easily take various postures within the cylinder case 24. 24, when the pack 10 is dropped from the hopper tank or the conveyor belt to the inlet of the cylindrical case 24, it is likely to be clogged due to a bridge phenomenon or the like. It is preferable that the diameter is larger than the diameter of 10 by about 5% to 20%.

  Further, the interval t between the opening edge 24b of the cylindrical case 24 and the receiving plate 27 is equal to or more than one sheet thickness of the pack 10 and less than two sheets. The inner diameter d of the opening 48 is determined in consideration of the diameter of the pack 10 as described above. However, if the inner diameter d is made larger with the interval t set larger, the amount of protrusion of the pack 10 from the opening 48 becomes larger. Thus, the center 10a of the pack 10 may reach the moving path of the extrusion plate 35. Then, since the push plate 35 pushes the vicinity of the center of the pack 10, the pack 10 becomes difficult to rotate and is pushed in that posture. Therefore, it is preferable to make the inner diameter of the opening 48 smaller when the interval t has a margin.

  As shown in FIG. 4A, when the subsequent pack 10 is stacked on the pack 10 before the pack 10 falls to the horizontal position, the lowermost pack 10 may remain inclined. Even in such a case, when the extrusion plate 35 moves as shown in FIG. 4B, the extrusion edge 35a contacts the outer peripheral edge of the inclined pack 10, and the pack 10 is rotated clockwise. Therefore, finally, as shown in FIG. 4C, the pack 10 accommodated in the cylindrical case 24 is entirely corrected to a horizontal posture. Therefore, even if the push plate 35 moves, the lowermost pack 10 is not discharged. However, if the pusher plate 35 is returned to the standby position and then moved again in the discharge direction, the lowermost pack 10 is surely removed. Can be extruded.

  6A, when the pack 10 is tilted in the reverse direction, when the extrusion plate 35 is moved, the extrusion edge 35a having a semicircular arc-shaped concave shape is formed as shown in FIG. The pack 10 comes into contact with the outer peripheral edge from both sides. As the push plate 35 moves in the direction of the arrow Y, the pack 10 is initially pushed to the left and moved. However, as shown in FIGS. 6B and 6C, the left end of the pack 10 is the cylindrical case. After coming into contact with the inner wall of 24, the right end side of the pack 10 is gradually pushed up by the movement of the push-out plate 35.

  As shown in FIG. 5, such push-up action reduces the distance between the two points of the push-out edge 35 a contacting the outer peripheral edge of the pack 10 as the push-out plate 35 moves in the arrow Y direction. Correspondingly to the right end side of the pack 10 entering the lower side of the extrusion plate 35, the length of the string connecting the two points where the extrusion edge 35a contacts is shortened. Conceivable. When the movement to the left is prevented, the right end side of the pack 10 is gradually lifted along with the movement of the push-out plate 35, and as a result, after the state shown in FIG. 10 is corrected to a horizontal posture. In addition, although two examples in the case where the pack 10 is inclined around an axis orthogonal to the moving direction of the extrusion plate 35 have been described, in cooperation with the opening 48 formed in the receiving plate 27 and the extrusion plate 35, the pack 10 In almost any direction, the same effect can be obtained.

  The operation of the pack delivery device 22 configured as described above is as follows. When a pack feed command is input from a predetermined terminal of the control circuit board 49 from the external device, the processing is started according to the flowchart shown in FIG. First, it is checked whether or not the second sensor 46 is on. This check is equivalent to confirming whether or not the push-out plate 35 is in the standby position shown in FIG. 2, and when the second sensor 46 is in the OFF state, it is fixed by the B timer built in the control circuit board 49. The motor 41 is rotated in reverse for a time (time b: about 3 seconds, for example). If the second sensor 46 does not turn on even after the time b has elapsed, it is determined that the push-out plate 35 is incapable of moving for some reason, the motor 41 is stopped, and an error notification is issued. 41 can be prevented from being burned out.

  When the second sensor 46 is turned on, it is determined that the push-out plate 35 is in the normal standby position. Similarly, the A timer starts measuring a predetermined time (time a: about 3 seconds, for example) and the motor 41 is rotated forward. Is started. As the motor 41 rotates forward, the feed plate 35 moves from the standby position toward the discharge position. If the first sensor 45 is turned on, it can be confirmed that the extrusion plate 35 has correctly reached the discharge position. If the first sensor 45 is not turned on even after the time a elapses, the operation of the push-out plate 35 is abnormal, so that the motor 41 is similarly stopped and an error is notified.

  When the first sensor 45 is turned on, the A timer is cleared, and “1” is added to the retry counter M that has been cleared to “0” prior to the forward rotation of the motor 41. Further, it is checked whether or not the discharge sensor 33 has already been turned on when the first sensor 45 is turned on. The discharge sensor 33 is turned on by the pack 10 until the push plate 35 moves to the discharge position while pushing the pack 10 by forward rotation of the motor 41. When the pack 10 is not discharged from the cylindrical case 24, the discharge sensor 33 remains off even if the push plate 35 moves to the discharge position indicated by the two-dot chain line in FIG.

  When the first sensor 45 is turned on, it is checked whether or not the discharge sensor 33 has already been turned on. If it is turned on, it means that the pack 10 has been properly discharged. set. Receiving the ON signal from the first sensor 45, the reverse rotation of the motor 41 is started when the reverse rotation of the motor 41 is started and the pushing plate 35 returns to the standby position. At this time, the presence / absence of the discharge flag is checked, and if the discharge flag is set, the proper discharge processing of the pack 10 has been completed, so the discharge flag is cleared and the one-cycle operation of the push-out plate 35 ends. Although the discharge number counter of the pack 10 is omitted, when the delivery command from the external device is for a plurality of packs, the discharge number counter is set according to the commanded number, and every time proper discharge is performed. The same process may be repeated while decrementing the discharge number counter by “1”.

  If the discharge flag is not set when the second sensor 46 confirms that the push-out plate 35 has returned to the standby position, either the pack 10 is not in the cylinder case 24 or FIG. As described with reference to FIG. 6, there is a high possibility that the extrusion plate 35 has been operated in order to correct the pack 10 accommodated in the tilted posture into a horizontal posture. Whether or not the inside of the cylinder case 24 is empty can be easily detected by providing, for example, a photo sensor or a micro switch. Therefore, the following description is based on the assumption that the pack 10 is accommodated in the cylinder case 24. To do.

  As described above, when the pack 10 is accommodated in an inclined posture, the posture of the pack 10 is only corrected to a horizontal posture by the movement of the push-out plate 35, and no discharge is performed. However, if the extrusion plate 35 is operated again, there is a high possibility that the extrusion plate 35 is properly discharged. In this embodiment, the extrusion plate 35 is automatically operated twice more. That is, the push-out plate 35 is automatically reciprocated between the discharge position and the standby position until the retry counter M reaches “2”. If the discharge flag is not set even if the pushing plate 35 operates for three convenient cycles, an error notification is given when the pushing plate 35 returns to the standby position and stops. As described above, the signals from the first sensor 45, the second sensor 46, and the discharge sensor 33 are monitored in combination, and by using the retry counter M, the A timer, and the B timer together, a highly reliable pack delivery The effect comes to be obtained.

  The disk feeding device of the present invention can also be applied to a coin dispenser that accommodates coins that are also disk-shaped workpieces and takes out a desired amount of money. FIG. 8 shows an example of a coin dispenser frequently used in, for example, a convenience store. Coins of respective amounts are accommodated in a vertical row in cylindrical cases 50a to 50f having an inner diameter corresponding to the diameter of the coin. Each coin is manually inserted into the cylindrical cases 50a to 50f. It should be noted that it is desirable that each cylindrical case be transparent so that the amount of coins can be recognized. Further, since the coins are manually inserted into the respective cylinder cases, the inner diameter of each cylindrical case does not need to have a sufficient margin with respect to the diameter of each coin, and can be set to an inner diameter of 5% or less of the coin diameter. .

  Inside the casing 51 of the coin dispenser, a feeding device having the structure described so far is incorporated for each cylindrical case. As mentioned above, it is not necessary for the inner diameter of each cylinder case to have a large margin with respect to the diameter of each coin, so coin clogging is less likely to occur, but the coins are prone to dirt and are slightly deformed. May also be included. Therefore, in the same manner as in the previous embodiment, an opening is formed in the backing plate for discharging foreign matter and correcting the posture of the tilted coin, and the disk feeding device of the present invention in which the extrusion edge of the extrusion plate is concave is used in combination. It is effective to do.

  When paying change to a customer who has made a purchase, the amount of change is input from the numeric keypad of the input panel 52. Since the input amount is displayed on the display panel 53, after confirming this, the enter key provided on the input panel 52 is operated. As a result, the type and number of coins corresponding to the amount of money are calculated, the pushing plates provided below the respective cylindrical cases 50a to 50f are operated for an appropriate number of cycles, and the change is automatically transferred to the discharge tray 54. Be paid out. In this coin dispenser and the pack delivery device described above, the cylinder case does not necessarily have to be vertical, and can be tilted within a range of about 30 degrees from the vertical line, for example.

    The present invention is provided with a cylindrical case for receiving disk-shaped workpieces having various diameters and thicknesses in a row, or a frame-shaped accommodation portion serving as a substitute for the cylindrical case, and the workpieces one by one as needed. It can be used for an apparatus for separating and discharging out of a cylindrical case. If the work has rigidity, it can be effectively used as a delivery apparatus for various disks handled as raw materials in the manufacturing process.
