2. Description of the Related Art Conventionally, a coin feeding device for feeding coins by means of an inclined disc is provided with an inclined disc whose upper portion is inclined toward the back, as described in Japanese Patent No. 2721142, for example. A storage hopper frame that forms a storage hopper for storing coins is disposed between the front area and the front surface. On the circumference of a predetermined radius position on the front surface of the inclined disc, a plurality of scooping protrusions that rotate in conjunction with the slanted disc to scrape coins in the lower region of the inclined disc one by one to the upper region are provided at a predetermined pitch. .

Then, by rotating and driving the inclined disc and the plurality of scraping projections, one coin in the lower region of the slanting disk is pushed by the scraping projections to the storage hopper wall of the storage hopper frame located at the peripheral edge of the sloped disk. While pushing along, it scrapes up to the upper area of the inclined disk, and sends out coins to the coin passage provided in the upper area of the inclined disk.

Then, by the rotation of the inclined disc 31, the scraping protrusions 46 enter from above and agitate the coins stored in the lower region of the inclined disc 31, and the coins stored in the lower region of the inclined disc 31. Among the scraping protrusions 46 adjacent to each other on the inclined disk 31, the scraping protrusion 46 engages with one coin that comes into surface contact with the lower surface 39.

At this time, in the pick-up protrusion 46 that does not correspond to the outer peripheral protrusion 52, the coins that are engaged are stored in the outer peripheral storage hopper wall 81.
While pushing along, scrape up to the upper area of the inclined disk 31.

The outer peripheral projections 52 located on the outer peripheral region of the inclined disc 31 are moved by the roller 61 so that the support plate 54 is directed toward the back of the inclined disc 31 when entering the predetermined rotation angle region S of the inclined disc 31.
