Abstract

Provided is a coin delivery device including a disc including a concave portion that holds a plurality of coins in a storage container one by one. A first concave portion that holds at least coins having a diameter equal to or larger than a first diameter, and a second concave portion that holds coins having a diameter less than a second diameter are provided in the disc. The first concave portion does not perform holding of coins having a small diameter or delivery of the coins to the next step, and the second concave portion performs holding of coins having a small diameter or delivery of the coins to the next step. Since the first concave portion does not hold two coins, and two coins are not put into the second concave portion, coins can be appropriately sent out one by one to the next step.

First claim

What is claimed is:

1. A coin delivery device comprising:
a disc that has a holding unit on an upper surface thereof, the holding unit holding a coin;
a storage container that stores a plurality of the coins; and
a supporting piece that presses side surfaces of the coins held by the holding unit to move the coins in a direction circumferentially outward from the disc,
wherein:
the coin delivery device is configured to hold the coins in the storage container by the holding unit and rotate the disc to send out the coins moving in the outer circumferential direction of the disc by the supporting piece one by one to a next step from a delivery port disposed on an upper side of the disc, and is configured such that the disc is disposed obliquely with respect to the storage container, and the storage container is disposed on a lower side of the disc,
the holding unit includes a first holding unit and a second holding unit which is smaller than the first holding unit, the first holding unit sending out only coins having a diameter equal to or larger than a first diameter to the next step from the delivery port and not sending out coins having a diameter less than the first diameter to the next step from the delivery port in a case where the number of coins held is one, and not sending out two coins held to the next step from the delivery port in a case where the number of coins held at the same time is two, and the second holding unit not holding coins having a diameter exceeding a second diameter smaller than a maximum diameter among the coins held by the first holding unit, and sending out the coin to the next step from the delivery port and not holding two coins having a diameter equal to or less than the second diameter at the same time in a case where the second holding unit holds one coin having a diameter equal to or less than the second diameter,
the first holding unit includes a first upstream side convex portion and a first holding base, the first upstream side convex portion being provided on an upstream side of the first holding base in a rotation direction of the disc, abutting on the side surfaces of the coins, and conveying the coins in the rotation direction of the disc, and the first holding base being disposed on a downstream side of the first upstream side convex portion in the rotation direction of the disc and having the coins placed thereon,
the second holding unit includes a second upstream side convex portion and a second holding base, the second upstream side convex portion being provided on an upstream side of the second holding base in the rotation direction of the disc, abutting on the side surfaces of the coins, and conveying the coins in the rotation direction of the disc, and the second holding base being disposed on a downstream side of the second upstream side convex portion in the rotation direction of the disc and having the coins placed thereon,
a portion of the second upstream side convex portion which abuts on the side surfaces of the coins and is closest to an outer circumference of the disc is disposed at a position closer to the outer circumference of the disc than a position of the first upstream side convex portion which abuts on the side surfaces of the coins and is closest to the outer circumference of the disc,
the first upstream side convex portion includes a supporting portion that supports the coins while abutting on the side surfaces of the coins, and an inclined portion which is disposed between the supporting portion and the outer circumference of the disc and becomes higher toward an upstream direction of the rotation direction of the disc from the first holding base, and
the coins having a diameter less than the first diameter are dropped into the storage container by the inclined portion.

2. The coin delivery device according to claim 1 , further comprising:
a blocking unit that blocks the sending-out of the coins from the first holding unit to the next step in a case where the coins having a diameter smaller than the first diameter are held by the first holding unit.

3. The coin delivery device according to claim 1 , wherein in a case where the first holding unit holds the coins having a diameter smaller than the first diameter, the first holding unit slides the held coins down until the first holding unit moves to a position facing the delivery port in association with rotation of the disc.

4. The coin delivery device according to claim 1 , wherein
the supporting piece includes a first supporting piece provided in the first holding unit, and a second supporting piece provided in the second holding unit,
a guidance surface that abuts on the side surfaces of the coins and guides conveyance of the coins is provided outside the outer circumference of the disc,
the first holding unit includes a first downstream side convex portion and the first supporting piece on a downstream side of the first holding base in the rotation direction of the disc, the first downstream side convex portion abutting on the side surfaces of the coins, and the first supporting piece moving the coins between the first upstream side convex portion and the first downstream side convex portion in a direction of the outer circumference, and the coins are conveyed in a state where at least three sides are surrounded by the first upstream side convex portion, the first downstream side convex portion, and the guidance surface, and are moved in a direction of the delivery port by the first supporting piece, and
the second holding unit includes a second downstream side convex portion and the second supporting piece on a downstream side of the second holding base in the rotation direction of the disc, the second downstream side convex portion abutting on the side surfaces of the coins, and the second supporting piece moving the coins between the second upstream side convex portion and the second downstream side convex portion in the direction of the outer circumference, and the coins are conveyed in a state where at least three sides are surrounded by the second upstream side convex portion, the second downstream side convex portion, and the guidance surface, and are moved in the direction of the delivery port by the second supporting piece.

5. The coin delivery device according to claim 4 , wherein the first supporting piece includes a pressing portion and a supporting piece inclined portion and slides the coins having a diameter less than the first diameter down into the storage container by the supporting piece inclined portion, the pressing portion abutting on the side surfaces of the coins and pressing the coins, and the supporting piece inclined portion being disposed in a portion of the upstream side in the rotation direction of the disc from a central portion of the first supporting piece and having a thickness that increases in a thickness direction of the first supporting piece toward a center of the disc.

6. A coin processing device comprising:
the coin delivery device according to claim 1 ;
an identification unit that receives the coins from the coin delivery device and identifies denominations of the coins; and
an accommodation unit that includes coin hoppers corresponding to the denominations of the coins and accommodates the coins in the coin hoppers,
wherein the coins are stored in the coin hoppers corresponding to the denominations identified by the identification unit.
