[Problem] To obtain a configuration having exceptional cleaning and maintenance performance. [Solution] There is provided a cleaner device (18) for cleaning a drug remaining in an annular groove (10) formed on a disc. The cleaner device (18) comprises: a cleaner body (21) on which is formed a bearing unit (26) having a suctioning unit (41), the cleaner body being positioned above a disc (8) a brush cover (23) supported by the bearing units (26, 27) of the cleaner body (21) so as to be capable of rotating about an axial center, the brush cover having a cylindrical section (66) connected to the suctioning unit (41) and a brush section (22) supported by the brush cover (23) so as to be capable of rotating about a shaft (67), the brush section being capable of sliding against the annular groove (10) by rotating about the shaft (67). The brush cover (23) rotates about the axial center to a cleaning position in which the brush section (22) is covered, and a standby position in which the brush section (22) is exposed. The brush cover is detachably attached, together with the brush section (22), to the cleaner body (21).[Problème] Pour obtenir une configuration ayant une efficacité de nettoyage et dentretien exceptionnelle.
