Abstract: Provided is a printer in which a cut-off paper is pushed into a paper stacking portion without an additional power source while reducing the maximum load applied to driving means for driving a movable blade. A printer includes a movable blade for cutting a paper disposed between a fixed blade and a movable blade as it moves in a forward direction and separating a printed part as a cut-off paper; driving means for moving the movable blade in a reciprocating manner; a pushing member which is driven to push a cut-off paper in a thickness direction of the cut-off paper; a paper stacking portion for stacking the cut-off paper pushed by the pushing member; and a driving force transferring mechanism for transferring a driving force of the driving means to the pushing member to drive the pushing member.

Abstract: In a power tool, a tubular gear case is disposed frontwardly of a motor and configured to accommodate a planetary gear speed reduction mechanism, a tubular motor bracket is attached to the motor and configured to connect the motor and the gear case together, and at least one pin is pierced through the motor bracket and the gear case to connect the motor bracket and the gear case together. The pin is engaged with a first-stage internal gear located at a first stage of the planetary gear speed reduction mechanism whereby the first-stage internal gear is restrained from rotating and located in position in an axial direction thereof.

Abstract: Three battery cells can be arranged such that one battery cell is situated on the front side of a handle portion and that the remaining two battery cells are situated on the rear side thereof while being arranged laterally side by side. Also, a handle portion can be generally of a triangular cross-sectional configuration whose apex portion is situated on the front side of the handle portion and whose base portion is situated on the rear side thereof; and the handle portion is grasped by bringing fingertips into contact with the apex portion (11a) on the front side.

Abstract: An electric caulking gun may include a cartridge setting portion to which a cartridge containing a caulking material can be set, an electric motor, a push rod driven by the electric motor via a power transmission path and configured to be pressed against the cartridge for dispensing the caulking material from the cartridge, and an interruption device provided in the power transmission path and operable for interrupting the power transmission path and allowing the push rod to be freely moved.

Abstract: In a speed change device of an electrical power tool, a reset arm is provided separately from a switch lever, which arm is operated by a reset motor. Due to tilting motion of the reset arm, a lock ring can be returned to an unlocking position in which a second stage internal gear can be rotated, so that the speed change device can be rest to a high speed low torque mode.

Abstract: In a power tool, a planetary gear speed reduction mechanism is provided in a gear case, and a spindle is configured to receive a torque of a motor transmitted through the planetary gear speed reduction mechanism. A final-stage internal gear is rotatably provided at a final stage of the planetary gear speed reduction mechanism. A clutch mechanism includes a coil spring configured to press the final-stage internal gear from a front side. The clutch mechanism is configured to cause the internal gear to run idle, thereby interrupting transmission of torque, at overload beyond a pressing force of the coil spring. An elastic member is interposed between an inner peripheral surface of the gear case and an outer peripheral surface of the final-stage internal gear, to give resistance to the final-stage internal gear at idle.
