摘要： An apparatus configured to discharge sheets may include pressing mechanism configured to downwardly press discharged sheets. For example, the pressing mechanism may include a first pressing member and a second pressing member. The first pressing member and the second pressing member may be located at least partially overlapping positions in the width-wise direction of the sheet. Additionally or alternatively, each of the first pressing member and the second pressing member may be configured to contact the sheet at different positions along a discharge direction. In one example, the different portions may be spaced apart from each other in the discharge direction.

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.

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： An image forming apparatus includes a fixing unit, discharge unit, first and second guides, and top cover. The discharge unit is disposed obliquely above a heating member of the fixing unit. The first guide extends from a position above the heating member toward the discharge unit and has an upstream portion in a conveying direction of an image-fixed sheet. The second guide is disposed above the heating member and faces the upstream portion. The second guide defines an upper portion of the conveying path. A part of the second guide faces the upstream portion in the first position, and exposes the upstream portion in the second position. The top cover is movable between an open position where the second guide is exposed and a closed position where the second guide is covered. The first guide has a guide surface sloping downward in the conveying direction.
