Abrégé

Coin hoppers which convey coins one at a time by means of a rotating body provided with separation holes are known. Provided is a highly durable coin hopper for which the durability of a pushing part of the rotating body for pushing a coin is increased.　The rotating body 5 has a tripartite structure comprising a first resin part 20, a second resin part 21, and a metal part 22. The first resin part 20 and the second resin part 21 are secured, and the metal part 22 is clamped. A portion of the metal part 22 is bent to form a pushing piece 25 for pushing coins, and the pushing piece 25 is exposed from the second resin part 21. In conjunction with the rotation of the rotating body 5, a coin 10 is pushed by the metal pushing piece 25, and moves along a base.

Provided are a ball bearing that has excellent heat resistance and can be manufactured at a low cost and a method for manufacturing this ball bearing. Surface processing by means of laser cladding is carried out in the circumferential direction on the outer circumferential surface of an inner ring 2 to form an annular first buildup layer 71 on which a plurality of balls 4 can make contact and roll in the circumferential direction (first buildup layer formation step). Surface processing by means of laser cladding is carried out in the circumferential direction on the inner circumferential surface of an outer ring 3 to form an annular second buildup layer 62 on which the plurality of balls 4 can make contact and roll in the circumferential direction (second buildup layer formation step).

This circular-plate delivery device is provided with a holding body 19 for holding a guide roller 17, and with an engagement position changing means which, along a circumferential path centered on the rotation axis of a rotating disk 30, changes the position of engagement of the holding body 19 with a base body 2, and which comprises a first tooth row 7, a second tooth row 19c, etc., which mesh with each other. In this configuration, regardless of the distance between a delivery roller 20 and the guide roller 17 (regardless of the size of a coin), the delivery roller 20 against which the coin is struck is smoothly moved in a reciprocation direction, and therefore coin jamming caused by the failure of movement of the delivery roller 20 can be prevented.

This circular-plate delivery device is provided with: a holding unit 18 which holds a delivery roller 20 so that the delivery roller 20 can reciprocate and which is a separate body from a base body 2; and an engagement position change means (first gear row 7, second gear row, a shaft support section 8, a tubular shaft 23, etc.) which, along a path in the direction in which the distance between the delivery roller 20 and a guide roller is changed, changes the position of engagement of the holding unit 18 with the base body 2. In this configuration, the position and attitude of the guide roller are maintained constant regardless of the size of a coin, and therefore the coin is appropriately guided by the guide roller toward a delivery passage regardless of the size of the coin.

An objective of the present invention is to prevent a coin jam (obstruction) in a currency disbursal path even when coins are disbursed simultaneously onto the same currency disbursal path from a plurality of coin disbursal devices arranged in up-down and front-rear directions. Currency type-specific disbursal/retaining devices are positioned in three tiers, and a plurality of the currency type-specific disbursal/retaining devices are positioned in each of the tiers. A currency disbursal path is disposed at least on each of the tiers, the currency disbursal paths are stacked vertically, and bottom plates of the currency disbursal paths incline downward toward a currency disbursal aperture side. A currency disbursal conveyor belt which is positioned facing obliquely upward toward the currency disbursal aperture side is positioned below the lower end parts of each of the bottom plates. Coins discharged from each of the currency type-specific disbursal/retaining devices initially descend from the currency disbursal paths onto an oblique plate, slide down the oblique plate, and thereafter descend onto the currency disbursal conveyor belt. The coins having descended onto the currency disbursal conveyor belt are conveyed to the currency disbursal aperture by the currency disbursal conveyor belt moving toward the currency disbursal aperture side.

A game parlor managing system in which the reliability of coin information in wireless communication in a game parlor is not degraded and an increase of game machines can be dealt with without changing the setting. A transmitter has coin identification units, child processing units connected to the respective coin identification units, and child wireless communication unit connected to the respective child processing units. A receiver has a parent processing unit and a parent wireless communication unit connected to the parent processing unit and communicating with the child wireless communication units. Communication channels among the parent and child wireless communication units are set up. Each child processing unit transmits coin information and check information to the parent wireless communication unit. The check information corresponding to the received information is verified. The coin information corresponding to the check information verified as correct is stored in the parent processing unit.
