Abstract

A tablet cassette is provided that can easily adjust the width of a guide groove of a rotor depending on the size of a tablet to be dispensed. The tablet cassette includes a groove width adjustment mechanism that relatively moves both sides of each of the tablet guide grooves in a circumferential direction of the rotor.

First claim

The invention claimed is:

1. A rotor for a tablet cassette rotatably disposed in a cassette body, the rotor comprising:
a plurality of tablet guide grooves extending in a rotation axial direction so that the tablets contained in the cassette body are discharged through the tablet guide grooves, wherein:
first and second side surfaces of each of the plurality of tablet guide grooves are formed by first and second movable plates which are movable relative to one another in a circumferential direction of the rotor, the first movable plate defining a first adjustment hole and a second adjustment hole, the second movable plate defining a third adjustment hole and a fourth adjustment hole; and
a groove width adjustment mechanism configured to move the movable plates in the circumferential direction of the rotor relative to one another to adjust a width of each of the plurality of tablet guide grooves in response to a size of the tablet, the groove width adjustment mechanism including an operating member having a first adjustment pin, a second adjustment pin, and a base interconnecting the first and second adjustment pins, the first adjustment pin passing through the first and third adjustment holes, the second adjustment pin passing through the second and fourth adjustment holes.

2. A tablet cassette comprising:
a cassette body for storing tablets;
a rotor rotatably disposed in a bottom portion of a tablet container of the cassette body, the rotor being formed with a plurality of tablet guide grooves extending in a rotation axial direction,
first and second side surfaces of each of the plurality of tablet guide grooves formed by first and second movable plates which are movable relative to one another in a circumferential direction of the rotor, the first movable plate defining a first adjustment hole and a second adjustment hole, the second movable plate defining a third adjustment hole and a fourth adjustment hole; and
a groove width adjustment mechanism configured to move the first and second movable plates in a circumferential direction of the rotor to adjust the width of each of the plurality of tablet guide grooves in response to the size of the tablet, the groove width adjustment mechanism including an operating member having a first adjustment pin, a second adjustment pin, and a base interconnecting the first and second adjustment pins, the first adjustment pin passing through the first and third adjustment holes, the second adjustment pin passing through the second and fourth adjustment holes.

3. The tablet cassette according to claim 2 , wherein
the first movable plate has a plurality of first adjustment walls, each of the plurality of first adjustment walls having the first side surface that forms one side of each of the plurality of tablet guide grooves; and
the second movable plate rotatably disposed relative to the first movable plate and having a plurality of second adjustment walls, each of the plurality of second adjustment walls having the second side surface that forms an other side of each of the plurality of tablet guide grooves opposed to the first side surface of the first movable plate.

4. The tablet cassette according to claim 2 , wherein
the third adjustment hole intersects the first adjustment hole and the fourth adjustment hole intersecting the second adjustment hole.
