Abstract

A device for dispensing medicine includes a dispensing device body 1, a cassette 2 fixed removably to the dispensing device body in order to contain medicines while arranging, and pushing means 18 for pushing out the medicines in the cassette 2 toward one end side. The cassette 2 includes a cover 6 and a stopping/receiving part 17 disposed internally in the longitudinal direction. The pushing means 18 includes an abutting part 19a contained in the cassette 2 and abutting against the medicines, an biasing part 20 for biasing the abutting part 19a against the medicine, and a stopping part 21 stopping at the stopping/receiving part 17 of the cassette 2 only when the cover 6 is opened. Consequently, the cassettes 2 can be arranged at a high density and a desired number of medicines can be dispensed surely.

Claims

1. A device for dispensing medicine, comprising:

a dispensing device body, a cassette fixed removably to the dispensing device body in order to contain medicines while arranging, and pushing means for pushing out the medicines in the cassette toward one end side,

the cassette including a cover to arrange the contained medicines and a stopping/receiving part disposed internally in a longitudinal direction, and

the pushing means including an abutting part contained in the cassette and abutting against the medicines, a biasing part for biasing the abutting part against the medicine so as to Press and arrange the medicines from one end side, and a stopping part stopping at the stopping/receiving part of the cassette only when the cover is opened so that the abutting part is prevented from pressing the medicines in conformity to biasing force of the biasing part, wherein when the abutting part is moved, the stopping part is released from the stopping/receiving part and the abutting part is moved to an arbitrary position so as to allow positioning.

2. The device for dispensing medicine as defined in claim 1, wherein the pushing means is constituted such that the biasing part and the stopping part are housed in a casing and one end face of the casing functions as the abutting part.

3. The device for dispensing medicine as defined in claim 1, wherein the cassette includes fallout preventing means for preventing contained medicines from falling out in a state that the cassette is dismounted from the dispensing device body, and

the dispensing device body includes a canceling part for canceling fallout prevention by the fallout preventing means when the cassette is mounted and a dispensing part for allowing the medicines in the cassette to be dispensed one by one.

4. The device for dispensing medicine as defined in claim 1, wherein the stopping/receiving part is constituted of a stopping rack composed of a plurality of recess parts juxtaposed along a longitudinal direction of the cassette, and the stopping part has a gear which rotates in response to opening and closing operation of the cover to engage with the stopping rack.

5. The device for dispensing medicine as defined in claim 4, wherein the pushing means includes a gear engaged with the stopping rack and an oil dumper integrated with the gear, and the biasing part is constituted of a constant-load spring.

6. The device for dispensing medicine as defined in claim 3, wherein the dispensing part is constituted of a rotor having a circular plane allowing medicines to be held one by one, the rotor being rotated by power transmitted through a gear provided on a rotating shaft, the gear being engaged with a rack formed on a rod, the rod being able to reciprocate.

7. The device for dispensing medicine as defined in claim 3, wherein the dispensing part is constituted of a rotor having a circular plane allowing medicines to be held one by one, the rotor being rotated by power transmitted through a gear provided on a rotating shaft, the gear being engaged with a drive gear which drives rotationally, the drive gear being able to come into contact with or break away from the gear of each rotor in a plurality of cassettes.

8. The device for dispensing medicine as defined in claim 3, wherein the fallout prevention means is constituted of a plate spring provided on one end aperture of the cassette, the plate spring being elastically deformable from being at a fallout prevention position for preventing medicines from falling out from the cassettes to being at a medicine dispensing position for permitting the dispensing part to dispense medicines.

9. The device for dispensing medicine as defined in claim 8, wherein the plate spring elastically supports a head medicine so as not to move a position of a next medicine when the head medicine received on the circular plane of the rotor is dispensed from the cassette by rotation of rotor.

10. The device for dispensing medicine as defined in claim 1, wherein the dispensing device body includes a pusher for driving the dispensing part of the cassette to dispense medicines and a stopping/retaining member geared to the pusher to engage with or disengage from the cassette.

11. The device for dispensing medicine as defined in claim 4, wherein the dispensing part is constituted of a rotor having a circular plane allowing medicines to be held one by one, the rotor being rotated by power transmitted through a gear provided on a rotating shaft, the gear being engaged with a rack formed on a rod, the rod being able to reciprocate.

12. The device for dispensing medicine as defined in claim 4, wherein the dispensing part is constituted of a rotor having a circular plane allowing medicines to be held one by one, the rotor being rotated by power transmitted through a gear provided on a rotating shaft, the gear being engaged with a drive gear which drives rotationally, the drive gear being able to come into contact with or break away from the gear of each rotor in a plurality of cassettes.

13. The device for dispensing medicine as defined in claim 4, wherein the fallout prevention means is constituted of a plate spring provided on one end aperture of the cassette, the plate spring being elastically deformable from being at a fallout prevention position for preventing medicines from falling out from the cassettes to being at a medicine dispensing position for permitting the dispensing part to dispense medicines.
