[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stapler provided with a driving device provided with a staple driving mechanism and a clincher device provided with a clincher groove for bending the driven staples so as to be relatively movable in parallel to each other.

[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 further sent to the discharge side. Therefore, it was necessary to change the paper in the other direction, and the paper moving mechanism had to be complicated.

Therefore, 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. Further, by adopting a method in which the driving device and the clincher device are moved in the horizontal direction with respect to each other, it is possible to move both devices on the same sheet and drive staples at different positions.

However, when moving the driving device and the clincher device, it is necessary to stop both devices at a position vertically aligned with each other.

[0006]

Object of the Invention The present invention has been made in view of the above circumstances, and comprises a staple driving device and a clincher device which are relatively movable so that the driving device can be aligned with the clincher device at the time of driving. It is an object of the present invention to provide a stapler that can be used.

[0007]

In order to achieve the above object, a stapler according to the present invention drives a staple in a staple storage section by a driving mechanism and is capable of moving in a direction perpendicular to the driving direction;
A clincher groove that bends a leg portion of the staple launched by the driving device, and a clincher device that can move in parallel with the driving device; and between the driving device and the clincher device that are positioned at the mutually aligned positions. a stapler spell by inserting the paper, the strike write a positioning member for positioning the alignment position and the driving device and the clincher device
Is provided on either or both of the viewing device and the clincher device, the positioning member, and the driving device
Is engageable to another side when moving the clincher device, spelling
Occasionally, it is withdrawn from between the driving device and the clincher device.
It is characterized in that it is formed to be evacuable .

[0008]

According to the above construction, when a sheet is inserted between the driving device and the clincher device and the driving device is driven, staples are punched out and penetrate the paper.
The sheet is bent by hitting the clincher groove of the clincher device, and the sheet is bound. Thereafter, the sheet can be moved in the same direction as the insertion direction, and can pass between the driving device and the clincher device. Therefore, the moving direction of the spelling of the paper can be simplified.

Further, when the positioning member provided on the driving device or the clincher device is engaged with the other during the movement,
Since both devices will always move the same amount,
It is always in a matching state both when it is stationary and when it is moving. Therefore, the spelling operation can be performed at any time. Note that the positioning member is not
Formed so that it can be retracted from between the insertion device and the clincher device.
Because of this, there is no hindrance to paper insertion and spelling operation.

1 shows an electric stapler, which comprises a driving device 1 and a clincher device 2. FIG.

The driving device 1 is provided with a staple storage portion in the frame 3 and drives out staples in the storage portion by a driving mechanism. The staple storage portion is a cartridge (not shown) that is detachable from the driving device 1.
The cartridge is mounted at a predetermined mounting position of the driving device 1.

The staple driving mechanism includes an electric motor 4, a driving link 5 driven by the electric motor 4, and a driver 6 operated by the driving link 5. The driving link 5 is driven by the electric motor 4, and the driving link 5 is driven. 5 is converted into a vertical motion of the driver 6.

A feeding mechanism (not shown) for supplying staples in the cartridge below the driver 6 and the like are provided below the driving device 1.

Further, brackets 7 are fixed to both sides of the driving device 1, and through holes 8 are formed in each bracket 7.

Next, the clincher device 2 includes a clincher groove 10 for bending the leg of the staple punched out by the driving device 1.
May be a fixed type integrally formed with the spelling table 11, but may be a movable type. Projections 13 are formed before and after the frame 12 of the clincher device 2, and the projections 13 are formed with through holes 9.

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 and a spelling stand are vertically separated from each other as disclosed, for example, in Japanese Utility Model Laid-Open No. 1-114285. Things are fine.

The through holes 8 and 9 of the driving device 1 and the clincher device 2 pass through moving rods 14 and 15 provided in parallel with other devices (not shown), whereby the driving device 1 and the clincher device 2 are connected. The moving rods 14, 1
5 is movably supported along the longitudinal direction.

Next, one end of a swing arm 16 is swingably supported on a side surface of the bracket 7 of the driving device 1 as a positioning member. When not in use, the swing arm 16 swings upward and retracts to the side of the bracket 7,
At the time of use, it swings downward to project below the driving device 1, and when swinging downward, the clincher device 2
Is provided so as to be engageable with a guide portion 17 formed on the side surface of the frame 12. When the swing arm 16 is engaged, the driver 6 of the driving device 1 and the clincher groove 10 of the clincher device 2 are set to correspond to each other at the matching position.

According to the above configuration, when the sheet 18 is inserted between the driving device 1 and the clincher device 2 and the stapler is operated when the driving device 1 and the clincher device 2 are at the position where they are aligned, the driving device operates. 1 driver 6
Is driven to eject the staples downward, and the legs thereof penetrate the paper 18 and further strike the clincher grooves 10 of the clincher device 2 so that the paper 18 is bound. Thereafter, the paper 18 can be moved in the same direction as the insertion direction, and can pass between the driving device 1 and the clincher device 2.

Next, when different positions are spelled by the same driving device 1 and clincher device 2, both devices 1, 2
Is moved along the moving rod 14. At this time, when the swing arm 16 of the driving device 1 is swung downward to be engaged with the clincher device 2 and moved, the clincher device 2 also moves by the same movement amount following the movement of the driving device 1. Then, when the driving device 1 is stopped at a predetermined position, the clincher device 2 is also stopped at a position where the driving device 1 is aligned. When the driving device 1 is operated again after the stop, the paper 18 is bound in the same manner as described above. Thereafter, the swing arm 16 is swung upward to clear the driving device 1 and the screw.
Lever is retracted from between the Pichincha device 2, the paper 18 can be moved passed between the same direction as the insertion direction of the driving device 1 and the clincher unit 2.

As described above, by swinging the swing arm 16 to engage with the clincher device 2, the driving device 1 and the clincher device 2 always move by the same amount, so that the device is stationary. Both the devices 1 and 2 are always in the aligned state both when moving and when moving. Therefore, the spelling operation can be performed by driving the driving mechanism of the driving device 1 at any time.

The driving device 1 and the clincher device 2
By providing a mechanism for moving the swing arm or a mechanism for swinging the swing arm 16, the efficiency of the spelling operation can be further increased.

Further, the positioning member is not limited to the structure for swinging the swing arm 16. For example, the arm may be moved up and down to engage the side surface of the clincher device 2. Alternatively, a configuration in which a pin is supported by a driving member so as to be movable up and down, and this is operated by a solenoid, and when the pin is moved down, the pin may be engaged with and disengaged from a hole formed in the clincher device 2 may be employed.

Further, the positioning member is the clincher device 2.
On both sides, or on both devices.
