That is, the top cover 6a of the apparatus body 6 is opened to expose the sweeper device 18. The sweeper device 18 is located in a relatively open space with no other parts near the front left side of the device body 6. Therefore, it is excellent in workability and can be easily cleaned.

Next, the body cover 24 is opened to expose the brush cover 23. Further, the grip brush cover 23 is press-fitted toward the telescopic catheter 41 side. Thereby, the duct main body 42 of the telescopic duct 41 is pressed into the opening 40 of the first bearing portion 26 against the thrust of the coil spring 49, and the first shaft portion 67 of the brush body 23 is the first from the second bearing portion 27. The tubular portion 37 is detached. As a result, the brush body 23 and the brush body portion 22 can be removed from the sweeper body 21. Moreover, the brush body portion 22 can be removed from the brush cover body 23 by removing the brush body drive gear 68 from the brush cover body 23. Further, the scraping member 80 can be easily removed from the brush body 23 by pressing the locking projection portion 55 to deform the elastic sheet 78 and sliding it toward the lower side.

Moreover, the brush body 23 and the brush body part 22 detached from the sweeper main body 21 can be attached to the sweeper main body 21 as follows.

That is, in a state where the brush body portion 22 has been assembled to the brush cover body 23, the connection barrel is The portion 73 is inserted into the first duct portion 46 of the duct body 42 and is pressed against the thrust of the spring 49. Then, the brush cover 23 is moved in the axial direction, and the first shaft portion 67 to which the second guide ring 72 is attached is inserted into the through hole of the second bearing portion 27. The lid body driven gear portion 75 and the brush body second intermediate gear 71 are respectively located on a circumference centered on the axis of the brush cover body 23. Further, a part of the intermediate gear 36 for the brush cover and the first intermediate gear 34 for the brush body are exposed in an engageable manner. Therefore, as described above, by moving the brush cover 23 in the axial direction, the cover body driven gear portion 75 can be smoothly meshed with the intermediate body gear 36 for the brush body, and the second body for the brush body can be used. The intermediate gear 71 is smoothly meshed with the first intermediate gear 34 for the brush body.

In this manner, the brush cover 23 and the brush body portion 22, which are likely to adhere to the powder medicine, can be easily disassembled by being detached from the sweeper body 21. Moreover, the scraping member 80 can also be easily removed from the brush cover body 23. Therefore, the cleaning of these components can be performed simply. In the cleaning of the brush body 23 and the brush body portion 22, the entire cleaning can also be performed, and the component (especially the brush body portion 22 or the scraping member 80) can be replaced even when it is deteriorated.

Further, it is preferable to use a suction duct 83 to suck the powder medicine scattered outside the disk 8. The suction duct 83 is liable to be damaged by the bellows-like hose 86 due to use. Therefore, when the hose 86 is damaged, the screwing state of the hose 86 is released from the nozzle guide 90, and only the hose 86 is removed and replaced. Therefore, since the nozzle portion 86 which is more expensive than the hose 86 is not replaced, the correspondence can be made in an inexpensive manner.

Further, in the above-described embodiment, the pair of bearing portions (the first bearing portion 26 and the second bearing portion 27) that face each other at a predetermined interval are formed in the sweeper body 21, but the bearing portion may be configured as a single holding structure. It is only one of the telescopic ducts 41 and the like. At this time, the shaft main body 62 of the brush body portion 22 is rotatably supported in the bearing portion, and the intermediate gear (the second intermediate gear 71 for the brush body) may be meshed at this position. Further, the bearing portion may be provided with a retaining mechanism to prevent the attached brush cover 23 from coming off. According to this configuration, the sweeper device 18 can be made more compact.

Further, the sweeper device 18 may be configured to support a rotatable single-hold structure in a single bearing portion as follows. That is, as shown in Fig. 22, the connection cylinder portion 73 is formed on one end wall of the brush cover body 23, and a flexible hose (not shown) is connected to the connection cylinder portion 73. Further, the cover body driven gear portion 75 is integrally formed on one end wall of the brush cover body 23, and the brush body second intermediate gear 71 is rotatably attached to the cover body driven gear portion 75 coaxially. Further, the brush body drive gear 68 that is integrated with the shaft member of the brush body portion 22 is exposed to the one end wall of the brush cover body 23, and is engaged with the second intermediate gear 71 for the brush body. In the same manner as the above-described embodiment, the cover body driven gear portion 75 is meshed with the brush cover drive gear 35 via the cover body intermediate gear 36, so that the driving force from the brush cover motor 32 is transmitted to The cover body 23 is brushed. In addition, the second intermediate gear 71 for the brush body meshes with the driving gear 33 for the brush body via the first intermediate gear 34 for the brush body, so that the driving force from the brush motor 31 is transmitted to the brush body 22. According to this configuration, it is possible to provide a mechanism for driving the brush cover 23 and the brush body portion 22 regardless of the connection cylindrical portion 73, so that the workability and the assemblability are excellent.

Other embodiments are described below. As shown in FIG. 23(a), the R disk 8 may have a weir portion 94 which is located outside the outer circumferential extending portion 11 and below or above the outer circumferential extending portion 11. Further, when the inner circumferential extending portion is formed inside the annular groove 10, the female portion 94 is located inside instead of the outer circumferential extending portion 11. The crotch portion 94 is supported by the support roller 93. When the crotch portion 94 is provided, the powder medicine can be reduced from entering the support roller 93 as compared with when the outer peripheral extending portion 11 is supported by the support roller 93. Therefore, the rotation of the R disk 8 is not hindered. In Fig. 23(b), the brush body 23 is extended up to the top of the crotch portion 94. Further, on the downstream side in the rotation direction of the R disk 8 at the time of cleaning (the downstream side of the brush body portion 22), the scraping piece 82 for preventing the powder spreading of the outer circumferential extending portion 11 and the annular groove 10 is formed, and formed. The crotch portion 95 is scraped on the crotch portion above the crotch portion 94. By means of the ankle scraping sheet 95, the powder of the crotch portion 94 can be surely also prevented, and the prevented powder is sucked. Further, in order to clean the other force of the crotch portion 94, a passage for easily sucking the drug can be provided from the crotch portion 94 to the telescopic catheter 41 (suction portion) or from the crotch portion 94 to the connection tube portion 73. In addition, the mounting plate 81 is omitted in FIG. 23(b).
