Abstract

A tablet dispenser includes a device body and a plurality of tablet cassettes disposed on one face of the device body. Each tablet cassette is capable of accommodating a plurality of types of tablets and of dispensing the tablets contained therein in a lateral direction. A plurality of chutes are in communication with the plurality of tablet cassettes. Each chute is disposed on the one face of the device body, adjacent to a corresponding tablet cassette. Each chute retains tablets dispensed from the corresponding tablet cassette and dispenses the tablets in a downward direction into a container.

Claims

1. A tablet dispenser comprising:

a device body;

a plurality of tablet cassettes vertically disposed on one face of the device body, each tablet cassette being capable of accommodating a plurality of tablets and of dispensing the tablets contained therein in a lateral direction; and

a plurality of chutes in communication with the plurality of tablet cassettes in a one-to-one relationship, each chute being vertically disposed on the one face of the device body and adjacent to a corresponding tablet cassette, wherein each chute retains tablets dispensed from the corresponding tablet cassette and dispenses the retained tablets in a downward direction into a tablet container,

wherein each tablet cassette is detachably coupled to the device body independent of the coupling of each corresponding chute to the device body such that each of the plurality of tablet cassettes is detachable from the device body while the corresponding chute remains coupled to the device body,

wherein the plurality of chutes comprise an entrance ortion and an exit portion, and

wherein the entrance portion is adjacent to a side of the respective tablet cassette and the exit portion extends away from the one face of the device body toward a front of the tablet dispenser.

2. The tablet dispenser according to claim 1, wherein the chutes extend obliquely downwardly away from the one face of the device body and are arranged such that a lower portion of a first chute overlaps with an upper portion of a second chute positioned immediately below the first chute, the second chute acting as a guide for placement of a tablet container into which tablets are dispensed from the first chute.

3. The tablet dispenser according to claim 1, wherein each chute comprises an opening through which the tablets may be dispensed, a degree of exposure of each opening being adjustable in accordance with a size of an open end of the tablet container into which the tablets are to be dispensed.

4. The tablet dispenser according to claim 1, wherein each chute comprises a gate member capable of alternately covering and exposing an opening of each chute, the tablets being dispensed through the opening of each chute when the opening is exposed.

5. The tablet dispenser according to claim 4, wherein each gate member comprises an abutment in contact with an interior surface of each chute, the abutment guiding movement of the gate member to prevent displacement of the tablet container.

6. The tablet dispenser according to claim 5, wherein the gate member comprises a gate plate and a guide portion for guiding in a manner such that the position of the lower portion of the chute is not changed when a gate plate is rotated.

7. The tablet dispenser according to claim 6, wherein the gate member further comprises a slide plate that moves in conjunction with the pivotable gate plate.

8. The tablet dispenser according to claim 4, wherein the gate member comprises a pivotable gate plate attached to each chute, the gate plate comprising a tab extending perpendicularly away from an exterior surface of the gate plate.

9. The tablet dispenser according to claim 4 further comprising an interlock having a first position and a second position, the interlock securing a removable cover to each chute when in the first position and the interlock retaining the gate member to expose the opening of each chute and enabling removal of the cover of each chute when in the second position.

10. The tablet dispenser according to claim 4, wherein the gate member comprises a plurality of plates radially biased inwardly toward each other and having a first position and a second position, the plates contacting each other to cover the opening of each chute in the first position and moving radially outwardly away from each other when a force is applied to a surface of the plates to place the plates in the second position, the opening of each chute being exposed when the plates are in the second position.

11. The tablet dispenser according to claim 1 the chute comprises a chute body and a cover which can be attached to and detached from the chute.

12. The tablet dispenser according to claim 11, wherein the chute body comprises a lock mechanism which locks the cover in the state that the cover is attached to the chute body.

13. The tablet dispenser according to claim 1, further comprising a first control member which controls the plurality of chutes so as to dispense tablets by driving one of the tablet cassettes in which appropriate tablets are accommodated based on the prescription data, wherein in the case that there are tablets which have already been dispensed to the chute and tablets to be dispensed to the chute are included in the following prescription data, the control member making the dispensing of the appropriate tablets from the cassette stop temporarily until tablets are dispensed from the chute.

14. The tablet dispenser according to claim 13 further comprising a display member displaying the number of the waiting prescription.

15. The tablet dispenser according to claim 14 further comprising a second control member for making the display member display so as to be able to discriminate whether a waiting prescription is a next prescription or a division prescription according to the same prescription.

16. The tablet dispenser according to claim 13 further comprising a third control member for making the display member display so as to be able to discriminate whether a waiting prescription is a next prescription or a division prescription according to the same prescription.

17. The tablet dispenser according to claim 1, further comprising a motor fixedly coupled to the device body, and operatively mechanically coupled via gear mechanisms to a driven member of the tablet cassette to enable dispensing of the tablets, wherein the tablet cassettes are disposed with virtually no gaps therebetween in a vertical direction.

18. The tablet dispenser according to claim 17, wherein the driven member is at least one of a rotor and a gear assembly.
