Abstract: The rack-type power supply device includes a plurality of battery modules each of which accommodates a plurality of secondary battery cells, a rack main body that vertically accommodates battery modules in a horizontal posture like a plurality of steps with gaps between the battery modules, and a plurality of cooling fans that are arranged on a front surface side of the rack main body and blow cooling air into the gaps between battery modules. The rack main body also includes a back-side duct in which cooling air having passed through the gaps flows upward on a back surface side of the battery modules. In addition, rack main body includes an air outlet for discharging cooling air having passed through the back-side duct on a top surface side. The cooling fan is disposed to be shifted from the gap between the battery modules in front view of the rack main body.

Abstract: An electric stapler is provided. In this electric stapler, a driver arm is made to oscillate by making a toggle link mechanism operate by a connecting rod that performs a crank operation by a driving gear driven to rotate by a motor. A staple is put into sheets of paper by means of a driver provided at a top end of the driver arm by downward movement of the driver arm. A clinch arm is made to oscillate by a cam provided in the driving gear. Both legs of the staple penetrating through the sheets of paper are clinched by means of a clincher by upward turning of the clinch arm caused by a paper-thickness adjusting spring provided between the clinch arm and the toggle link mechanism. Due to this structure, driving load can be reduced and formation precision of each component does not affect clinching precision directly.

Abstract: An electric stapler capable of handling multiple sheets of paper. A motor-driven pair of wheel gears turn a swing arm having a symmetrical structure for driving a staple firing assembly and a clinch mechanism, thereby applying large pressure uniformly on staples. The clinch mechanism bends staple legs in different directions so that they do not overlap each other, preventing the clinched part of paper from increasing in the thickness of the stacked paper.

Abstract: In a cassette loading device of a compact, lightweight, thin type for use in a video tape player or the like, an opening lever is pivotally mounted on a stand, and is engaged in a cam groove with a top plate. With this arrangement, the opening lever is accommodated within a longitudinal dimension of a cassette, and therefore the loading device in the direction of the longitudinal dimension of the cassette can be greatly reduced. The cassette is moved through the pivotal movement of the top plate and arms, and with this arrangement operating switches and so on can be easily mounted on a plane of projection of the top plate. Therefore, the positional stability of the cassette loading device can be achieved, and the number of component parts can be reduced, thereby achieving a compact, lightweight construction of the cassette loading device.

Abstract: A tape loading apparatus in a video tape recorder has first and second tape drawing mechanisms movably supported between an unloading position, in which they are accommodated within respective recesses in a tape cassette containing magnetic tape, and a loading position in which a portion of the magnetic tape is urged around a tape guide cylinder. At least one of the tape drawing mechanisms includes a tape drawing member and a tape guide member. A tape protective member for preventing any possible entry of a portion of the magnetic tape in between the tape drawing member and the tape guide member is mounted on top of the tape guide member so as to partially overhang the tape drawing member.
