摘要： A wire-type print head comprises an armature to which a rear end of a printing wire is fixed, a core having its forward end adjacent to a rear surface of the armature, a leaf spring having a first end fixed near a permanent magnet and a second end fixed to the armature, and an auxiliary core positioned between the permanent magnet and the core, and having a forward end adjacent to the rear surface of the armature. An electric current is made to flow through a coil wound on the core for generating a magnetic flux through the core in a direction to cancel the magnetic flux due to the permanent magnet. When the coil is not energized the armature is attracted toward the core to resiliently deform the leaf spring. When the coil is energized the armature is released and moved forward by the action of the leaf spring. The rear surface of the armature is kept in contact with the front end of the auxiliary core so that the front end of the auxiliary core forms a fulcrum point for swinging of the armature.

摘要： A transfer roller is used in an electrophotographic printer. The transfer roller rotates in contact with a rotating photoconductive drum with a print medium travelling therebetween. The transfer roller has a metal shaft around which a rubber roller is formed. The rubber roller is sponge-like and electrically semiconductive. The rubber roller is covered with a resin tube which has a lower layer formed on the rubber roller and an upper layer formed on the lower layer. One of the upper and lower layers has a higher sealing effect than the other of the upper and lower layers, and the other of the upper and lower layers has a higher stability of electrical resistance than the one of the upper and lower layer.

摘要： A mechanism for mechanically coupling a driving source and a driven member. The mechanism includes a first member coupled to the driving source and a second member coupled to the driven member. A resilient member exerts a force to bring the first and second members into pressure contact at a contact surface. A vibration is excited in the contact surface of the first member to produce a levitation force, based on an ultrasonic levitation, acting upon the second member. Frictional force between the first member and the second member is changed depending on the levitation force, thereby changing power transmitted between the first member and the second member.

摘要： A spring-charged wire dot print head having printing wires is provided with back poles paired up respectively with the cores of electromagnets for cancelling the magnetic flux produced by a permanent magnet, to eliminate the adverse effect of magnetic interference liable to occur in driving the adjacent printing wires. The adjacent pairs of cores and back poles are opposite to each other with respect to the polarity of the magnetic path of the magnetic flux produced by the permanent magnet.
