Coin delivery device and coin processing device

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.
