Abstract

A coin feeding device (for example, feeding unit 20) includes: a disk 22 having a plurality of protrusions 22b at a surface, the disk 22 disposed so as to be rotatable in a tilted state and configured to catch coins by the protrusions 22b to move the coins upward while rotating; a cover 21 configured to form a space for storing a coin between the cover 21 and the surface of the disk 22; a guide 26 configured to guide a peripheral edge of a coin such that a part of the coin having been caught by each protrusion 22b and moved upward protrudes from the disk 22; and a taking-out unit (for example, taking-out mechanism 28) configured to grip only one coin protruding from the disk 22, remove the coin from the disk 22, and discharge the coin to outside of the disk 22.

First claim

The invention claimed is:

1. A coin feeding device, comprising:
a disk having a plurality of protrusions on a surface of the disk, the disk disposed so as to be rotatable in a tilted state, and the disk configured to catch coins by the protrusions to move the coins upward while rotating;
a cover configured to form a space for storing a coin between the cover and the surface of the disk;
a guide configured to guide a peripheral edge of a coin, while the peripheral edge of the coin is in contact with the guide, such that a part of the coin having been caught by each protrusion and moved upward protrudes from the disk; and
a taking-out mechanism configured to grip one coin protruding from the disk, remove the coin from the disk, and discharge the coin to outside of the disk, wherein
the guide is provided out of the disk such that a gap is formed between the guide and an outer peripheral edge of the disk, and
in a case where the disk rotates, a centrifugal force acts on the coin caught by the protrusion, and the coin is moved toward the guide and brought into contact with the guide.

2. The coin feeding device according to claim 1 , wherein
the taking-out mechanism includes a gripping portion that approaches the disk in synchronization with approaching of the protrusion, and
the gripping portion performs a gripping operation of gripping one coin protruding from the disk when approaching the disk, and performs a releasing operation of releasing the gripped coin when having moved away from the disk.

3. The coin feeding device according to claim 2 , wherein the gripping portion performs the releasing operation in which a contact portion that comes into contact with a coin for gripping the coin is moved away from an upper surface of a body portion over a distance greater than a largest thickness of thicknesses of coins to be handled, and performs the gripping operation in which the contact portion approaches the upper surface of the body portion such that a distance between the contact portion and the upper surface of the body portion is less than a smallest thickness of thicknesses of coins to be handled.

4. The coin feeding device according to claim 3 , wherein the gripping portion grips a coin between the upper surface of the body portion and the gripping portion.

5. The coin feeding device according to claim 3 , wherein
the taking-out mechanism further includes a cam for moving the contact portion, and
the cam allows the contact portion to approach the upper surface of the body portion such that a distance between the contact portion and the upper surface of the body portion is less than the smallest thickness of thicknesses of coins to be handled when the gripping portion approaches the disk.

6. The coin feeding device according to claim 3 , wherein at least one contact portion grips the coin at one point.

7. The coin feeding device according to claim 2 , wherein the gripping portion grips a coin by a force for restoring a contracted spring to a neutral state.

8. The coin feeding device according to claim 2 , wherein the taking-out mechanism includes a regulator for preventing two or more overlapping coins from being gripped by the gripping portion, to prevent two or more coins from being simultaneously discharged to outside of the disk.

9. The coin feeding device according to claim 8 , wherein the regulator regulates a coin passage of the surface of the body portion through which coins protruding from the disk pass.

10. The coin feeding device according to claim 8 , wherein the regulator is detachable from the taking-out mechanism.

11. The coin feeding device according to claim 9 , wherein
a plurality of the regulators are disposed, and
each of the regulators regulates a coin passage of the surface of the body portion.

12. The coin feeding device according to claim 11 , wherein each of the regulators is detachable from the taking-out mechanism.

13. The coin feeding device according to claim 1 , wherein the taking-out mechanism rotates about an axis parallel to a rotation shaft of the disk.

14. The coin feeding device according to claim 13 , wherein the taking-out mechanism rotates in a direction opposite to a rotation direction of the disk.

15. The coin feeding device according to claim 1 , wherein the taking-out mechanism is movable between a position close to the disk and a position apart from the disk.

16. The coin feeding device according to claim 1 , wherein the guide is further away from a center of the disk than the plurality of protrusions are from the center of the disk.

17. The coin feeding device according to claim 1 , wherein the disk, the plurality of protrusions and the guide all intersect a same plane.

18. The coin feeding device according to claim 1 , wherein the taking-out mechanism is further away from a center of the disk than the plurality of protrusions are from the center of the disk.

19. The coin feeding device according to claim 1 , wherein the disk, the plurality of protrusions and the taking-out mechanism all intersect a same plane.

20. The coin feeding device according to claim 1 , wherein the gap is along a direction parallel to a radius of the disk.
