Abstract: A cartridge includes a holding portion movable, by movement of a developing member in an axial direction of the developing member, between a first position for stably holding a second unit at a spaced position and a second position for stably holding a second unit at a developing position. The cartridge also includes an urging portion for urging the holding portion in a direction from the second position toward the first position in the axial direction of the developing member. At least one of the first gear portion and the second gear portion is a helical gear. When the second gear portion is driven and rotated by the first gear portion, the holding portion is moved from the first position to the second position by the second gear portion receiving a force from the first gear portion. When the second gear portion is not driven by the first gear portion, the holding portion is moved from the second position toward the first position by an urging force of the urging portion.

Abstract: Power can be efficiently generated in accordance with the amount of water in a channel by including: a first headrace channel positioned on an upstream side; a second headrace channel positioned on a downstream side; a water wheel on a most downstream side of the first headrace channel and the second headrace channel, the water wheel having a rotation shaft in a direction orthogonally intersecting with a water flow; a lateral movement apparatus that enables the second headrace channel to be moved in an upstream direction or a downstream direction; and a vertical movement apparatus that enables the water wheel to be moved in a vertical direction.

Abstract: A slide rail unit for guiding an object to be pulled out, such as drawer, from a body, such as furniture or desk, in which the object is slid ably accommodated includes a body side rail provided for the body, and an object (i.e., drawer) side rail provided for the object to be pulled out to be slidable relative to the body side rail. The body side rail and the object side rail each has a portion bent in a circular-arc shape so that the object is pulled out along a circular-arc locus.

Abstract: To provide a movable body driving device which has simple structure and is capable of moving a movable body in a certain direction and automatic drawer equipment. A movable body driving device is provided which comprises a roller 12 as a rotary member which is rotatably supported on an inner frame 11 as a supporting member and a motor 13 for rotating the roller 12. The roller 12 is brought in contact with the movable body, which is adapted to be movable in a certain direction, with predetermined force using elastic force of coil springs 21, 22, 23 as elastic members. The movable body is moved by frictional force between the movable body and the roller 12. Automatic drawer equipment employing the movable body driving device as its drawer driving mechanism is also provided.
