摘要： A housing includes at least one openable cover and at least one adjacent cover. The at least one openable cover swings on a hinge to separate an interior of the housing from an exterior of the housing. The at least one openable cover has a first side edge on a side of the hinge. The at least one adjacent cover is adjacent to the at least one openable cover. The at least one adjacent cover has a second side edge neighboring the first side edge of the at least one openable cover across a gap. One of the at least one openable cover and the at least one adjacent cover includes at least one projection projecting into the gap and another one of the at least one openable cover and the at least one adjacent cover includes a recess that accommodates the at least one projection in the gap.

摘要： A drive system includes multiple vibrating members that tend to vibrate when these members are driven and a holding system to hold the multiple vibrating members. The holding system at least includes a first holding unit and a second holding unit superimposed on and partially connected to each other. The multiple vibrating members include a first vibrating member and a second vibrating member. The first vibrating member is held by the first holding unit and is not held by the second holding unit. The second vibrating member is held by the second holding unit and is not held by the first holding unit. At least one of the first vibrating member and the second vibrating member is a driving device to drive another member as a drive source.
