In a rechargeable battery in which an electrode plate group () obtained by superimposing a positive electrode plate (), in which positive electrode material () is attached to a positive electrode current collector (), and a negative electrode plate (), in which negative electrode material () is attached to a negative electrode current collector (), with a separator () therebetween is accommodated in a battery container () together with electrolyte, the current collectors () of the electrode plates () are respectively projected at opposite ends of the electrode plate group (), forming by themselves flat planes () by being pressed, and current collecting plates () are joined to these flat planes ().

Rechargeable battery

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.

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.

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.
