Disk feeding device

A disk feeding device including:

• a base body;
• a hopper head that stores a disk;
• a rotary disk that is disposed in the base body and is rotatable;
• a feeding passage that is provided in the base body and through which the disk fed toward an outside of the disk feeding device passes;
• and
• a guide roller and a feeding member that face each other via the feeding passage,
• the rotary disk including a circular through hole that penetrates in a rotation axis direction and a push protrusion that pushes the disk in a rotation direction to move the disk, and moving the disk that is sent to the rotary disk from the hopper head and passes through the through hole with the push protrusion in the rotation direction,
• the guide roller guiding the disk moved to a predetermined position of the rotation direction toward the feeding passage,
• the feeding member being capable of reciprocating in a direction in which a distance from the guide roller is changed, and feeding the disk pinched between the feeding member and the guide roller by a biasing force of a biasing member while being biased toward the guide roller by the biasing member, the disk feeding device comprising:
• a holder that holds the guide roller;
• a first lock for changing a locking position of the holder with respect to the base body along a track in a circumferential direction centered on the rotation axis;
• regulation pins that guide the disk toward the feeding passage in a radial direction while coming into contact with the disk pushed by the push protrusion and moved in the rotation direction to regulate a movement of the disk in the rotation direction;
• a pin bracket that holds the regulation pins;
• and
• a second lock for changing a locking position of the pin bracket with respect to the base body along a track in a circumferential direction centered on the rotation axis.
