Further, there is a copier including an electric stapler simultaneously binding a plurality of locations of paper by a plurality of the electric staplers and there is a copier successively binding a plurality of locations of paper by moving a single piece of the electric stapler by a feed mechanism.
Further, according to a copier constituted to laminate paper on the feed table by disposing a copy face of paper to a lower side for convenience of collation, in order to penetrate a staple from tail to head of paper, the driver unit of the electric stapler is arranged below the sheet table and the clincher unit is arranged above the sheet table. The staple guide of the driver unit is brought into a hole formed at the sheet table from a lower side to be brought into contact with paper face, the clincher unit on the upper side is moved down and pinches paper on the sheet table along with the staple guide and leg portions of the staple penetrating paper from the lower side are folded to bend by the clincher.
Although the electric stapler is constituted by a structure of charging the staple cartridge from an upper side or a rear face side, inside of the copier is occupied by the copying mechanism portion and normally, there is not a space sufficiently for attaching and detaching the staple cartridge.
Therefore, in interchanging the staple cartridge, a total of the unit of the electric stapler must be drawn out of the copier to this side by opening a front cover of the copier.
Therefore, there is posed a fifth problem that time and labor is taken in operation of attaching and detaching the staple cartridge and replenishing the staple.

Next, a detailed description will be given of a fourth embodiment of the invention in reference to the drawings. FIG. 14 is a front view of an electric stapler, FIG. 15 is a side view and FIG. 16 is a sectional view taken along a line XVI-XVI of FIG. 14 and FIG. 16 illustrates states of moving a clincher unit and the driver unit to an initial position (left) in the skewed binding position (right). In the drawings, numeral 401 designates the frame, numeral 402 designates the sheet table made to span a middle portion in an up and down direction of the frame 401, the clincher unit 403 is arranged on an upper side of the sheet table 402, the driver unit 404 is arranged on a lower side of the sheet table 402 and the clincher unit 403 and the driver unit 404 are respectively engaged with linear guides 405 provided at a ceiling face and an inner bottom face of the frame 401 and moved between an initial position of the left side and the skewed binding position on the right side.
FIG. 32 through FIG. 35 are explanatory views of a horizontal rotating mechanism of the electric stapler and in the drawings, a lower end of the linear guide 505 is a front cover side end portion disposed on a rear side of a front cover of a copier, an upper end (not illustrated) thereof is a rear face side end portion and when the front cover is opened, the front cover side end portion disposed on this side is exposed.
A right side of the front cover side end portion of the linear guide 505 is arranged with the first stopper pin 521 and the second stopper pin 522 in parallel with the linear guide 505.
Lower ends of the clincher holder 634 and the spacer 635 are formed with the guide faces 638 inclined to rise from a front edge portion or a rear edge portion to inside of the clincher holder 634 and as shown by FIG. 41, the guide faces 638 are arranged in correspondence with position of penetrating the leg portion to the staples. As described above, the clincher unit 622 can finely moved in the front and rear direction at inside of the front and rear cover frames 619, 620 and therefore, even when a position of the leg portion of the staple S is more or less shifted in the front and rear direction, by striking a front end of the leg portion to the guide face 638, the clincher unit 622 is moved frontward or rearward, the front end of the leg portion of the staple S is made to advance between the clincher holder 634 and the spacer 635 and accurately brought into contact with the lower face of the clincher 630. In this way, the clincher unit 622 is provided with an automatic aligning mechanism, thereby, a concern of a failure in clinching by shifting a position of striking the staple is resolved. Further, since the two leg portions of the staple S are held between the clincher holders 634 and the spacers 635 respectively until finishing to clinch the staple S and the two leg portions are separated by the spacers 635, the two leg portions are clinched in parallel and there is not a concern of overlapping and intersecting the two leg portions.
Next, an explanation will be given of a constitution of the clincher unit 703 in reference to FIG. 50 through FIG. 52. As shown by FIG. 50, the clincher drive motor 713 is arranged upwardly at a rear portion of the clincher frame 714 for driving to rotate the gear 716 at a final stage via a middle gear 715.
The gear 716 in a spur gear shape is supported at the gear holder 717 fixed to the clincher frame 714 at two upper and lower faces thereof and the screw shaft 718 is screwed to a screw hole formed at a center thereof.
FIG. 51 is a disassembled view showing a lifting type clinch mechanism portion of the clincher unit from a rear side (right side of FIG. 50) and a cabinet of the clinch mechanism portion is constituted by the front and rear cover frames 719, 720 and an upper support frame 721. Numeral 722 designates the support plate integrated to the cover frames 719, 720 to be able to move in an up and down direction by a small amount.
Vertically long square holes 723 and 724 are formed at upper half portions of the front and rear cover frames 719, 720, a gear 716 is brought in mesh with the middle gear 715 shown in FIG. 50 via the square hole 724 of the rear side cover frame 720, and when the gear 716 is rotated in the counterclockwise direction in view from an upper side, in FIG. 51, portions other than the gear 716 and the gear holder 717 in FIG. 51 are integrally moved down and contrary thereto, when the gear 716 is rotated in the clockwise direction, the portions are moved up.
Next, an explanation will be given of steps of operating the clincher unit 703 in reference to FIG. 55 through FIG. 58( b). FIG. 55 and FIG. 58 (a) show an initial state and when a start signal is inputted to the electric stapler from the state, the driver drive motor (not illustrated) and the clincher drive motor 713 are started. In the driver unit 704, the linear staple sheet of the staple cartridge 771 is fed to the front side by the staple feed cam 751 shown in FIG. 53, the forming plates start rising by being retarded slightly from the staple feeding operation to form a front staple in a gate-like shape. In the clincher unit 703, the clincher drive motor 713 is rotated to drive to rotate regularly the gear 716 shown in FIG. 55 and FIG. 58( a) in the counterclockwise direction in view from the upper side to move down a total of the clinch mechanism portion. Further, when the slider 734 is grounded to a surface of paper P on the sheet table and is moved up relative to the clinch mechanism portion, the claw 737 at a left side face of the slider 734 shown in FIG. 51 presses the actuator of the grounding sensor 742 to input the grounding detecting signal to the control circuit, and the control circuit stops the clincher drive motor and becomes stationary in a state of pressing paper by the front and rear cover frames 719, 720 as shown by FIG. 76 and FIG. 58( b).
Next, a detailed description will be given of an eighth embodiment of the invention in reference to the drawings. FIG. 60 is a front sectional view of a left side portion of an electric stapler, the clincher portion A8 comprising the clincher carriage 801 and the clincher unit 802 is arranged on an upper side, the driver portion B8 comprising the driver carriage 803 and the driver unit 804 is arranged therebelow, and the clincher portion A8 and the driver portion B8 are opposed to each other by interposing a sheet table (not illustrated) arranged at a middle in an up and down direction. FIG. 61 is a front sectional view showing the clincher portion A8 and the driver portion B8 and FIG. 62 is a sectional view taken along a line LXII-LXII of FIG. 61.
