Abstract: A stapler capable of avoiding defective clinching and buckling of legs even if the stapler is of a vertically-separated type in which a driver unit and a clincher unit are separated vertically is disclosed. This stapler is provided with clincher members (133 and 134) for clinching legs of a staple driven out by a driver and holders (131 and 132) which hold the clincher members (133 and 134). Also, in this stapler, guide surfaces (131b and 132b) for guiding tips of the legs of the staple toward the clincher members (133 and 134) are formed on upper surface portions of the holders (131 and 132), and the holders (131 and 132) are movable in a direction perpendicular to a surface which includes a direction that the legs of the staple are clinched.

Abstract: A stapler made with an upside down structure and used in downside up position in which loading of the cartridge is easily attained, is provided. The stapler comprises a base plate 21 which is fixed on a top board 13, a bracket 30 which is rotatably attached to an arm board portion 25 of the base plate 21, a stapler body 40 which is attached to the bracket 30 and a stopper 70 which fixes the stapler body 40 in its downside up posture.

Abstract: A feed roller 32 is disposed in a magazine section 1 such that the feed roller 32 is in press contact with the lower side of a sheet-like staple fed out of a cartridge 13. A rack is formed in the support means of the magazine section 1. The feed roller 32 is operatively coupled with the magazine section 1 through a one-way clutch gear 34 in mesh with the rack 33. Only when the magazine section 1 separates from the clincher section 4, the one-way clutch gear 34 operates to rotate the feed roller 32 in the staple supply direction. The rotation of the one-way clutch gear 34 can be adjusted by a gear ratio of the combination of the one-way clutch gear 34 and the rack 33. Therefore, a sufficient quantity of feeding the sheet-like lowest staple is secured. The feed roller 32 is rotated by utilizing the forward/backward motion of the magazine section 1 with respect to the clincher section. Therefore, provision of any special drive means for rotation is not required.

Abstract: An electric stapler is provided including a body frame; a magazine fixedly secured to the body frame; a cartridge housing a plurality of staple sheets, each of the staple sheets including straight staples conjoined together in stacked state, the cartridge being coupled to the magazine. A driver is provided for driving a staple out of one of the staple sheets; the driver being supported by the magazine so that the driver can be rectilinearly reciprocated. A clinching member is provided for clinching the staple driven out by the driver. The clinching member is supported by the body frame so that the clinching member is located to face the driver and can be reciprocated. A member is provided for repeatedly moving the driver and clinching member toward and away from each other in mutually opposite directions nearly simultaneously, so that as the driver is moved downwardly to drive the staple into material to be stapled, the clinching member moves upwardly in supporting relation with the material.

Abstract: An Electric stapler of the type in which a magazine is unmovably fixed, characterized in that the magazine is secured to a body frame; a driver for driving out a staple is supported by the magazine so that the driver can be rectilinearly reciprocated; a clincher, which receives the staple driven out by the driver, is supported by the frame so that the clincher is located to face the driver and can be reciprocated on the production of the direction of the reciprocation of the driver; the driver is coupled to drive links at one end of each thereof; the links are supported by the frame so that the links are swingable; the clincher is coupled to a clincher lever at one end thereof; the lever is supported by the frame so that the lever is swingable; the links and the lever are associated at the other ends thereof with a drive control cam, which is rotated by an electric motor; and the driver and the clincher are nearly simultaneously moved toward and away from each other in mutually opposite directions through the
