The present invention relates to a medicine delivering device, and more specifically, to a printer in which an ink ribbon can be easily detached and attached.
Conventionally, as indicated in patent document 1, a medicine delivering device is known which is composed of: a drum-type medicine storage and removal unit that is fitted with many medicine cassettes; and a medicine packaging part that packages a medicine taken out from the medicine storage and removal unit. This medicine delivering device comprises a printer that performs, by use of an ink ribbon, predetermined printing of a patient name, a dose period, dose regimen, and the like on packaging paper for packaging the medicine. In installation of the ink ribbon into the printer, it is required to insert an ink tape of the ink ribbon between a printer head and a backup roller thereof. With a conventional printer of the medicine delivering device, the interval between the printer head and the backup roller thereof is very narrow, thus making it difficult to insert the ink tape therebetween. Patent Document 1 Japanese Unexamined Utility Model Publication No. 1991-35003.
It is an object of the invention of this application to provide a medicine delivering device including a printer in which an ink tape can be inserted easily and also in which an ink ribbon can be detached and attached easily.
To achieve the object described above, the present invention refers to a medicine delivering device including a printer that performs predetermined printing, by use of an ink ribbon, on packaging paper for packaging the medicine. The medicine delivering device includes:
a stationary member that is provided in a device body,
a movable member that is movably provided to the stationary member,
a printer head that is swingably provided to the movable plate,
a backup roller that is provided to the stationary plate and that opposes the printer head,
an ink ribbon that is detachably provided to the movable plate and that guides an ink tape to the printer head,
and a tension bar that is swingably provided to the stationary plate and that presses the ink tape to thereby adjust a tensile force thereof. In the medicine delivering device, a swinging mechanism is further provided which swings the printer head and the tension bar in mutually opposing directions when the movable member moves. More specifically, the present invention refers to the medicine delivering device including the printer that performs predetermined printing, by use of the ink ribbon, on packaging paper for packaging the medicine. The medicine delivering device includes:
a stationary member that is provided in the device body,
a movable member that is movably provided to the stationary member,
a printer head that is swingably provided to the movable plate,
a backup roller that is provided to the stationary plate and that opposes the printer head
an ink ribbon that is detachably provided to the movable plate and that guides the ink tape to the printer head,
a tension bar that is swingably provided to the stationary plate and that presses the ink tape to thereby adjust the tensile force thereof,
a printer head swinging mechanism that swings the printer head so that the printer head approaches toward the backup roller via the packaging paper and the ink ribbon when the movable member is moved so that the printer head advances toward the backup roller and that swings the printer head so that the printer head separates from the backup roller when the movable member is moved so that the printer head retreats from the backup roller,
and a tension bar swinging mechanism that swings the tension bar so that the tension bar presses the ink tape in the direction opposite to the direction in which the printer head moves when the movable member is moved so that the printer head advances toward the backup roller and that swings the tension bar so that the tension bar separates from the ink tape in the direction opposite to the direction in which the printer head moves when the movable member is moved so that the printer head retreats from the backup roller.
According to the configuration described above, when the movable member is moved so that the printer head retreats from the backup roller, the printer head swings so as to separate from the backup roller, and the tension bar swings so as to separate from the ink tape in the opposite direction to the direction in which the printer head moves. Since the gap between the printer head and the backup roller widens and the tension bar separates from the ink tape, the ink tape can be more easily inserted between the printer head and the backup roller After the ink ribbon is fitted, when the movable member is moved so that the printer head advances toward the backup roller, the printer head approaches the backup roller via the packaging paper and the ink ribbon, and the tension bar swings so as to press the ink tape in the opposite direction to the direction in which the printer head moves, thus permitting printing with the ink ribbon.
It is preferable that the printer head swinging mechanism include:
a holding member that holds the printer head,
a support shaft that rotatably fits the holding member to the movable member and that swingably supports the printer head
an actuating lever that is fitted to the support shaft,
and a first and a second projecting pieces that are fitted to the stationary member and that contact with a part of the actuating lever when the movable member advances and retreats.
It is preferable that the tension bar swinging mechanism include:
a swinging lever that holds the tension bar and that is rotatably fitted via the support shaft to the movable member,
a biasing member that biases the tension bar in the direction in which the ink tape is pressed,
and a contact piece that is fitted to the stationary member and that contacts with a part of the swinging lever when the movable member retreats.
It is preferable that, in the medicine delivering device, the movable member is provided with the pressing member that is provided adjacently to the printer head and that presses, against the backup roller, a portion of the packaging paper located on a side opposite to a side of a portion thereof opposing the printer head with respect to a line folding the packaging paper in half. In this case, it is preferable that the pressing member is provided to the support shaft of the printer head and is biased by the biasing member in the direction in which the backup roller is pressed.
There are two types of medicine delivering device: a large-size type that includes approximately 150 to 300 fittable medicine cassettes; and a small-size type that includes 150 or less medicine cassettes. Thus, a medicine delivering device of an appropriate size is selected in accordance with a supply of a medicine demanded by a medicine store or a pharmaceutical department at a hospital where the medicine delivering device is used. At a small medicine store or a small hospital, in terms of reducing the installation space, a small-size medicine delivering device is preferred which has a small drum diameter that permits a minimum number of medicine cassettes. With a small-size medicine delivering device, the number of existing medicine cassettes may become unsatisfactory due to expansion of the medicine store or the hospital, an increase in the number of patients, introduction of a new medicine, or the like. In such a case, purchasing a large-size medicine delivering device requires high costs and also increases the installation space.
Thus, in a medicine delivering device having a medicine storage and removal unit in which many medicine cassettes each containing medicine are detachably provided to the outer surface of a drum whose upper and lower ends are rotatably supported by the device body
and a Medicine packaging unit that packages a medicine taken out through a collecting hopper from the medicine cassette of the medicine storage and removal unit,
there is provided on the side surface of the device body a sub medicine storage and removal unit including:
a body;
a drawer body that is so provided as to be capable of being pulled out from the body and that is detachably provided with a plurality of medicine cassettes each containing the medicine;
and a guide that guides the medicine taken out from the medicine cassette to the collecting hopper.
It is preferable that the medicine cassette of the drawer body be arranged on the side surface of the drawer body. In this case, the medicine cassette may be further provided on the front surface of the drawer body. Moreover, it is preferable that, above the guide, a shutter be provided which receives a medicine taken out from the medicine cassette of the drawer body. Further, it is preferable that, between the collecting hopper and the guide, a transfer device be provided which transfers the medicine collected in the guide to the collecting hopper.
In this manner, providing the sub medicine storage and removal unit on the side surface of the device body permits additional medicine cassettes to be provided at low cost without greatly enlarging the installation space.
According to the present invention, when the movable member is moved so that the printer head retreats from the backup roller, the gap between the printer head and the backup roller widens and the tension bar separates from the ink tape. This permits the ink tape to be more easily inserted between the printer head and the backup roller and thus permits the ink ribbon to be more easily detached and attached.
The device body 2 has a vertically long cubic shape, has a front upper portion and a front lower portion thereof provided with doors 6 and 7 respectively, and has a central portion thereof drawably provided with a manual medicine distributor 8. The upper door 6 is provided with an operation panel 9 and a journal printer 10 for printing medicine data and the like when the manual medicine distributor 8 is used. The lower door 7 is provided with a discharge port 11 for discharging a belt of medicine package from the medicine packaging unit 4 The upper door 6 is further provided with a bar code reader 9a, so that, when a bar code written on an original box containing a medicine is held against this bar code reader 9a, a medicine cassette 13, to be described below, for this medicine moves to the front side of the door 6.

In the medicine delivering device 1 with the structure as described above, medicine taken out from the medicine cassette 13 of the sub medicine storage and removal device 5 is temporarily received by the shutter 47 of the upper guide 42. When the shutter 47 opens the medicine is guided to the medicine extruding unit 44 through the lower guide 43. The medicine extruded from the medicine extruding unit 44 is guided to the lower collecting hopper 16, where the medicine joins a medicine guided from the medicine storage and removal unit 3 or the manual medicine distributor 8 of the device body 2. Then when a shutter 24 of the lower collecting hopper 16 opens, the medicine is guided to the packaging paper 26 through the packaging hopper 17, sealed by the heater roller 29, and discharged as the packaging band 26′ from the discharge port 11 of the device body 2.
In replacement of the medicine cassette 13 of the sub medicine storage and removal device 5, the door 40a of the main body 40 is opened and the drawer body 41 is pulled forward, whereby the medicine cassette 13 appears on the side surface, thus permitting replacement. Moreover, even while the medicine cassette 13 of the sub medicine storage and removal device 5 is performing dispensing operation, the door 40a of the main body 40 can be opened to replace the medicine cassette 13 located on the front surface, thus not requiring suspension of the dispensing operation.
The sub medicine storage and removal device 5 is provided on the side surface of the device body 2 of the medicine delivering device 1 in this manner. Therefore, when medicines can no longer be stored only with the medicine cassettes 13 (for example, 130 cassettes) of the medicine storage and removal device 3 on the device body 2 side, providing the sub medicine storage and removal device 5 permits additional 32 medicine cassettes 13 to be provided. This eliminates the need for purchasing a new large-size medicine delivering device and permits providing additional medicine cassettes 13 at low costs without greatly enlarging the space.
