Abstract

There is shown and described an improved electromagnetic bail actuator for use in a printer. The improvement arises from a simplified design resulting in a decrease in parts required as well as time needed for assembly which may be performed by a computer controlled robot, such as the IBM RS/1. In the figure, flat spring 2 performs three functions. Spring 2 maintains the proper relative positions between armature 4 and yoke 6, biasing one end of armature in cantilevered position in yoke 6. Spring 2 also biases bobbin 8 onto yoke 6, thereby eliminating the need for applying any separate fastening means during the assembly process. The third function performed by spring 2 is restoring armature 4 to its home position against upstop 10. The nonmagnetic material of bobbin 8 is substantially thinner in area 12.

Bail Actuator

There is shown and described an improved electromagnetic bail actuator for use in a printer. The improvement arises from a simplified design resulting in a decrease in parts required as well as time needed for assembly which may be performed by a computer controlled robot, such as the IBM RS/1. In the figure, flat spring 2 performs three functions. Spring 2 maintains the proper relative positions between armature 4 and yoke 6, biasing one end of armature in cantilevered position in yoke 6. Spring 2 also biases bobbin 8 onto yoke 6, thereby eliminating the need for applying any separate fastening means during the assembly process. The third function performed by spring 2 is restoring armature 4 to its home position against upstop 10. The nonmagnetic material of bobbin 8 is substantially thinner in area 12. Area 12, corresponding in shape to that portion of yoke 6 on which bobbin 8 is mounted, serves to substantially eliminate the tendency of armature 4 to remain sealed after relaxation of the magnetic field. Armature 4 is thus subject to controlled travel over the distance
14.
