<p><P>PROBLEM TO BE SOLVED: To provide a cartridge capable of preventing a first rotation body from rotating during inspection. <P>SOLUTION: A cartridge comprises: a rotation body 56 to be detected (a first rotation body) that has a pushed unit 75 and is constituted movably in an axial direction of rotation; an agitator gear 55 that has a pushing unit 68 and transmits driving power to the rotation body 56 to be detected; a coil spring 105 for energizing the rotation body 56 to be detected toward a housing 13; and a gear cover 46 for covering the rotation body 56 to be detected and the agitator gear 55. The rotation body 56 to be detected can move in the axial direction to a first position where the pushing unit 68 and the pushed unit 75 can be engaged with one another and to a second position that is farther than the first position from the housing 13 and where the pushing unit 68 and the pushed unit 75 cannot be engaged with one another, and, when being in the first position, rotates by engagement of the pushing unit 68 with the pushed unit 75. The gear cover 46 has a slit-shaped hole 104 long in the axial direction disposed radially outward from the rotation body 56 to be detected, to expose a gap between the rotation body 56 to be detected and the housing 13. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
