Abstract

PURPOSE:To eliminate adjusting work, to simplify the structure and to reduce the size by forming a guide section on a member for supporting a coil movably in a predetermined direction and engaging a guide piece, secured to a fixed substrate, with the guide section. CONSTITUTION:Upon conduction of a coil 3, the coil 3 and an armature support 4 begin linear motion in the Y direction through electromagnetic force. A pin 7 secured to a base plate 8 is inserted into an elongated hole 41 while maintaining a gap. Consequently, the pin 7 can guide the linear motion in the Y direction of the armature support 4 in the X and Z directions. Since the coil supporting member is provided with the guide function of linear motion, the number of parts is reduced and thereby the size is reduced resulting in facilitation of assembling and adjusting works.
