Abstract:
1. A set, comprising: a target apparatus including a mount assembly having an upper wall, a pair of side walls and an access opening; a mountable unit attachable to and detachable from the mount assembly through the access opening; a stationary plate adapted to be secured to the mountable unit; a movable plate adapted to be attached to the stationary plate and to be slidable with respect to the stationary plate in an insertion direction in which the mountable unit is inserted into the mount assembly and in a removal direction opposite to the insertion direction, the movable plate including an elastically displaceable portion having a protuberance; the stationary plate including a slide guide and a surface having a relief hole adapted to receive the protuberance, wherein movement of the mountable unit in the insertion direction into the mount assembly causes the protuberance of the elastically displaceable portion to contact the slide guide on the stationary plate, displacing the elastically displaceable portion outwardly in a lateral direction substantially orthogonal to the insertion direction and pressing the elastically displaceable portion into contact with at least one side wall of the mount assembly, thereby securing the mountable unit to the mount assembly, and movement of the movable plate in the insertion direction causes the protuberance of the elastically displaceable portion to locate in the relief hole in the stationary plate, displacing the elastically displaceable portion inwardly in the lateral direction to release the contact between the elastically displaceable portion and the at least one side wall of the mount assembly, thereby releasing the mountable unit for removal from the mount assembly.
