Title: High speed printing head having fulcrum structure
Inventor: OKUNA KENJI
IPC: B41J2/28
Filed: 1987-05-08
Abstract: PURPOSE:To achieve high speed printing and enhance productivity and reliability, by providing the fulcrum brought into contact with the effective elastic part of a leaf spring, which drives an armature toward a printing medium by allowing a current to flow to an electromagnetic coil, to the base body of a printing head. CONSTITUTION:When a current is allowed to flow to each of coils 9 and the magnetic flux due to a permanent magnet 11 is cancelled by a core attracting surface 82, the core attracting surface 82 and a yoke upper surface 121 are set to reference planes and a plate is laminated thereon to be assembled and, therefore, positional accuracy is easy to take and productivity is enhanced. When attraction force F acts on the armature 1, reaction forces R1, R2 are respectively generated at the fulcrum and a fixed end. The reaction force R2 becomes the same direction as the attraction force F and the reaction force R1 of the fulcrum part becomes the sum of F and R2 in a static balanced state. This fulcrum reaction force R1 prevents the separation of a leaf spring from the fulcrum even when the attraction force F is extremely strong and impact force acts on the end of a wire in a printing manner and the armature can be stably operated at a high speed.

Abstract: PURPOSE:To facilitate creation and restoration of the internal magnetization of a magnetoresistor pattern by a method wherein a conductor pattern which creates the internal magnetization in the magnetoresistor pattern has conductors through which currents flow along the direction approximately perpendicular to the longitudinal direction of the magnetism detecting parts of the magnetoresistor pattern. CONSTITUTION:A magnetoresistor pattern for external magnetic field detection is formed on the top surface of an insulating substrate 2 and, after an insulating layer 4 is formed on it, a conductor pattern is formed on the insulating layer 4 to form a magnetoresistance element 1. The magneto-resistor pattern has a plurality of magnetism detecting parts 3a and 3b extending to the left and right directions shown in the figure and the conductor pattern which creates internal magnetization (i) in the magnetism detecting parts 3a and 3b has a plurality of conductors 5a through which currents flow along the direction approximately perpendicular to the magnetism detecting parts 3a and 3b. Therefore, a magnetic field for creation and restoration of the internal magnetization can be induced by applying a relatively small current to the conductor pattern temporarily. With this constitution, the internal magnetization can be created and restored easily while the conventional high sensitivity is maintained.
