Claim:
A movable body moving apparatus, comprising: a pair of sliders slidably provided on one of a movable body and a fixed body, said pair of sliders comprising a first slider and a second slider and having an impelling device which pulls the two sliders toward one another; a first engaging part which is provided on the other of the movable body and the fixed body, and a second engaging part which is spaced relative to the first engaging part in a sliding direction of the pair of sliders; a first slide lock which is provided on the one of the movable body and the fixed body, and a second slide lock which is spaced relative to the first slide lock in the sliding direction of the pair of sliders; and means for releasing the second slider from the second slide lock when the second slider is locked in the second slide lock; said movable body moving apparatus being arranged such that: before a forward movement of the movable body relative to said fixed body, the second slider is locked in the second slide lock and prevented from sliding in the sliding direction by the second slide lock, and the first slider is slidable in the sliding direction while catching the first engaging part therein; in an end position of the forward movement of the movable body relative to said fixed body, the first slider is locked in the first slide lock and prevented from sliding in the sliding direction by the first slide lock while releasing the first engaging part therefrom, and the second slider is slidable in the sliding direction while catching the second engaging part therein; when moving the movable body from the end position of the forward movement backward to a prescribed position, the second slider is moved away from the first slider and a force is accumulated in the impelling device; and when the movable body reaches the prescribed position, the second slider releases the second engaging part therefrom and is locked in the second slide lock and prevented from sliding in the sliding direction by the second slide lock, and the first slider catches the first engaging part therein.
