BACKGROUND OF THE INVENTION
The present invention relates to a medal collection conveyor for conveying medals used in gaming machines such as slot machines.
[0002]
[Prior art]
As shown in FIG. 5, for example, a slot machine 1 which is a gaming device is generally installed in a group of devices called a so-called slot island in which a large number of machines are arranged. In this example, the slot machines 1 are arranged alternately with the medal lending machines 3. On the slot island, a medal collection box 5 is provided. In the collection box 5, medals from the individual slot machines 1 are conveyed by a medal collection conveyor 7. Each slot machine 1 is provided with a storage tank (not shown) so that a predetermined amount of medals are stored. However, when the amount of stored medals exceeds a predetermined amount, the recovery conveyor 7 overflows. Thus, it is collected in a collection box 5 provided on the slot island.
[0003]
By the way, the medals that are the game media of the slot machine 1 are attached with dust generated by contact between medals or contact between the medals and the device, and oil and fat by hand. These dusts and oils and fats adhere to the surface of the medal as dirt that cannot be easily removed by using the medal for a long time. Conventionally, in order to remove such dirt, a dedicated polishing machine is used, and the collection box 5 with a predetermined medal storage amount is periodically set in a polishing machine installed elsewhere, and the medal surface The dirt was scraped off by polishing.
[0004]
[Problems to be solved by the invention]
As described above, in order to keep the medal in a clean state, a polishing machine that periodically removes the adhered dirt has been used. As this polishing machine, for example, a nylon micro-cylindrical polishing material (referred to as a pellet) and a medal are put together and rotated with a spiral stirrer, and the dirt fixed to the medal is scraped off with the pellet. There were things that used hot water to clean the dirt stuck to the medal.
However, these polishing machines are for removing stubborn dirt adhered to the surface of the medal, and are large-scale and expensive.
Further, every time the medal storage amount reaches a predetermined amount, it is necessary to carry a heavy collection box to the polishing machine, which requires time-consuming work periodically. If an automatic polishing machine is installed on the slot island in order to eliminate such transportation work, a large installation space is required and the equipment cost increases.
The present invention has been made in view of the above circumstances, and can recover a medal that can always maintain a medal in a clean state without using a large-scale and expensive polishing machine, and can eliminate a medal transport operation for polishing. The purpose is to provide a conveyor.
