[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separation type stapler positioning mechanism for positioning a driving device having a staple driving mechanism and a clincher device having a clincher groove for bending the driven staples at mutually aligned positions.

[0002]

2. Description of the Related Art In a conventional stapler in which a staple driving device and a clincher device are rotatably connected at a base portion, a sheet inserted between the driving device and the clincher device is reversed in the insertion direction after spelling. It is extracted.

Recently, a copying machine has been practiced in which copied paper is stapled with a staple and then discharged to a take-out side. When a conventional stapler is built in the copying machine, a driving device and a clincher device are used. Then, after spelling, the sheet is extracted again in the direction opposite to the insertion direction, and is sent to the discharge side. Therefore, it is necessary to change the paper in multiple directions, and the moving mechanism of the paper must be complicated.

In order to simplify the moving direction of the paper, the driving device and the clincher device are separated so that the paper can pass between the driving device and the clincher device, and the spelled paper is inserted. It may be discharged in the same direction as the direction.

[0005] However, when the driving device and the clincher device are attached to another device or member such as a copying machine, it is necessary to fix both devices at a position vertically aligned with each other.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a positioning mechanism in a separate type stapler in which a driving device and a clincher device can be mounted at a position where they are aligned with other devices and members such as a copying machine. Its purpose is to provide.

[0007]

In order to achieve the above object, a positioning mechanism in a separation type stapler according to the present invention includes a driving device for driving a staple in a staple storage portion by a driving mechanism, and a staple driven by the driving device. And a clincher device having a clincher groove for bending the legs of the separate stapler for inserting and spelling a sheet between the driving device and the clincher device. The present invention is characterized in that at least three matching holes are provided at the corresponding positions, and pins are inserted into the positioning holes to position the punching device and the clincher device.

[0008]

According to the above configuration, when the driving device and the clincher device are attached and fixed to a part of a device such as a copying machine to form an electric stapler, the pin is inserted into the positioning hole of the driving device. And each pin is fitted into a positioning hole of each projecting piece of the clincher device. As a result, the driving device and the clincher device are positioned at the matching positions by the pins, and the driving device and the clincher device may be attached to the device while maintaining this state.

According to the electric stapler constructed as described above, when a stapler is operated by inserting a sheet between the driving device and the clincher device, the driver of the driving device is driven to drive the staples downward, and The leg portion penetrates the sheet, and then bends into the clincher groove of the clincher device, whereby the sheet is bound. afterwards,
The paper can be discharged by passing between the driving device and the clincher device.

As described above, according to the positioning mechanism, even if the stapling device and the clincher device are separated, the two devices can be easily positioned at the matching position by the pin, and the mutual positions can be determined. Since it is attached in a state where it is accurately positioned, a good spelling state can be obtained even when used after the attachment.

1 and 2 show an electric stapler.
This stapler includes a driving device 1 and a clincher device 2.

The driving device 1 includes sliding projections 4a on both sides of the magazine portion 4 in vertically elongated guide grooves 3a formed in the frame 3.
Is provided so as to be slidable in the vertical direction (see FIG. 2), and staples in the magazine portion 4 are driven out by a driver 5 at the front end. The staples are constituted by cartridges (not shown) which are detachable from the magazine portion 4. Then, the cartridge is mounted at a predetermined mounting position of the driving device 1.

The staple driving mechanism includes a drive link 7 driven by an output from an electric motor M via an intermediate gear 6 and a driver 5 operated by the drive link 7. Drive the
The swing motion of the drive link 7 is converted into the vertical motion of the driver 5, and the staple sent to the front end by a feed mechanism (not shown) is driven downward by the driver 5.

Next, the clincher device 2
5 ′ is provided with a clincher groove 8 for bending the leg of the staple driven by the driving device 1;
The clincher groove 8 may be a fixed type integrally formed with the spelling table 9, but may be a movable type.

The driving device 1 and the clincher device 2 have a structure in which a staple driving portion including a conventionally known electric stapler magazine as disclosed in Japanese Utility Model Laid-Open No. 1-71083 and a spelling stand are vertically separated. It is good.

Next, horizontal projecting pieces 10 and 11 are respectively formed from the lower part of the frame 3 of the driving device 1 to the front and back, and similarly, the horizontal projecting pieces are respectively formed from the upper part of the frame 15 'of the clincher device 2 to the front and rear. 12 and 13 are formed. A positioning hole 14 is formed in each of the projecting pieces 10 to 13. Each positioning hole 14 is set so that the driving device 1 and the clincher device 2 are aligned with each other, that is, the driver 5 of the driving device 1 and the clincher groove 8 of the clincher device 2 correspond to each other.

Reference numeral 15 denotes a pin.
Are formed so as to fit into the positioning holes 14 of the overhanging pieces 10 to 13. A flange 15 a is formed on the head of each pin 15 in a direction perpendicular to the axis of the pin 15.

According to the above-described configuration, the driving device 1 and the clincher device 2 are connected to a part p of a device such as a copying machine, for example.
When the electric stapler is formed by attaching and fixing to the q, a pin 15 is fitted into the positioning hole 14 of the driving device 1 and each pin 15 is fitted into the positioning hole 14 of each projecting piece of the clincher device 2. As a result, the driving device 1 and the clincher device 2 are positioned at the matching positions by the pins 15, so that the driving device 1 and the clincher device 2 may be attached to the device while maintaining this state.

According to the electric stapler constructed as described above, when the spelling sheet 18 is inserted between the driving device 1 and the clincher device 2 and the electric motor M is operated,
The magazine portion 4 of the driving device 1 slides downward and the driver 5 is driven to drive the staples downward, the legs of which penetrate the spelling sheet 18 and further bend by hitting the clincher grooves 8 of the clincher device 2 to be bent. 1
8 is spelled out. Thereafter, the sheet 18 can be discharged by passing between the driving device 1 and the clincher device 2.

As described above, according to the positioning mechanism, even when the driving device 1 and the clincher device 2 are separated from each other by the electric stapler, the pins 15 can easily position both devices at the matching position. Since they can be attached with their mutual positions accurately positioned, a good spelling condition can be obtained even after use after attachment.

Note that it is not necessary to form four projecting pieces and four pins for positioning.
