Abstract
To remove a contact condition between a contact and a lead of an IC package, a movable plate is moved forwardly from a control position to a release position by pivoting a crank lever, which includes a crank shaft portion having an eccentric shaft portion, from a starting point to a terminal point. The starting point of the forward pivotal movement of the eccentric shaft portion of the crank shaft portion is set in a third or fourth quadrant of a rectangular coordinate system with its origin at the rotation axis of the crank shaft portion (i.e. the starting point of the central axis of the eccentric shaft portion is disposed below the rotation axis of the crank shaft portion).
