Title: Printing head driver of line printer
Inventor: KITADOU MASAHARU
IPC: B41J2/28
Filed: 1985-10-25
Abstract: PURPOSE:To minimize the difference between suction force and spring force by providing a concave part in an auxiliary yoke set upright along the front of a leaf spring and inserting an iron piece fixed to the leaf spring in the concave part in freely movable manner. CONSTITUTION:A coil 4 is wound around each comb wheel 3a of an iron core 3 having a permanent magnet 2 in a magnetic channel and a comb-tooth tip, and an impact head 4 is attached to the tip of a leaf spring 5 provided in an opposite position to the end of each comb tooth 3a. The rear of each leaf spring 5 is always sucked to the end of each comb tooth 3a by the magnetic flux of the permanent magnet 2. If a pulse current is applied to a coil 4, the leaf spring 5 is released from the suction force of the permanent magnet 2 to perform a printing action. To minimize a magnetic resistance to the permanent magnet 2, an auxiliary yoke 6 is set upright along the front of the leaf spring 5 group. If the coil 4 is excited by the pulse current, the magnetic flux generated by the permanent magnet 2 is cancelled by a magnetic flux on the coil 4, and the leaf sprint 5 is restored by its own spring force, thus enabling the impact head 1 to perform dot printing.
