Abstract

PROBLEM TO BE SOLVED: To make a depth constant and beautifully finish a stapler by fixing a barrier member made of an elastic body on a right angle surface base at an arbitrary location of a main shaft direction from a groove location of an anvil provided on a base. SOLUTION: A barrier member made of an elastic body is a V-shaped member 1 formed by a spring metallic plate or a resin plate of 0.1 to 0.5 mm, for instance. The V-shaped member 1 is fixed to an arbitrary location of the direction of a main shaft 3 from a groove 2 of an anvil, that is, on a base 4 of a right angle surface of 10 mm, for instance. When an end face of paper is put to the V-shaped member 1 and a binding is performed, the binding of 10 mm in depth is made. According to the number of binding limit sheets of paper, the height of the barrier member of the V-shaped member 1 is determined. Because the V-shaped member 1 is pressed by a frame 6 and is deformed at the time of the binding and enters into a gap between the frame 6 and the base 4, an operation is not hindered.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stapler for stapling staples.

[0002]

2. Description of the Related Art Some conventional staplers are provided with a scale line provided on a base for depth alignment and a movable barrier when binding staples.

[0003]

These have the following disadvantages. Conventionally, when binding a sheet bundle with two left and right staples, there has been no function of positioning the two left and right staples. With this method, it is difficult to balance the left and right sides, which causes a disadvantage that the appearance is impaired, and the punch holes and staples often interfere with each other due to misalignment in the punching press work performed later. In addition, when positioning the staples, the depth can be determined by using a graduation line on the base or by attaching a movable barrier member.In these methods, the end of the paper bundle is graduated. It has to be adjusted each time to the line or the movable barrier has to be aligned, which is troublesome. The present invention has been made to eliminate these disadvantages.

[0004]

In order to determine the depth of the staple binding, a V-shaped spring-like member is fixed on the base at an arbitrary right angle in the direction of the main axis from the position of the groove of the anvil. A barrier at the end of the bundle. The positioning of the left and right staples is performed by attaching an arm member having an L-shaped tip to the back surface of the base so as to be freely rotatable.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The depth of staple binding is determined simply by abutting the end of a sheet bundle on a spring-shaped V-shaped member 1. FIG. Since the V-shaped member 1 requires elasticity, it does not hinder the operation of the staple binding at all.
In the case of the right side, the left and right staples can be positioned by rotating the arm member 4 rightward so as to be perpendicular to the base 3 and then hitting the L-shaped sheet bundle at the leading end. Good. When binding on the left side, the arm member 4 may be rotated to the left.

[0006]

1 and 2 show the case of a hand-type stapler according to an embodiment, in which a V-shaped metal plate having a thickness of 0.1 to 0.5 mm or a resin plate is used. Character 1
Are fixed on the base 3 at a right angle to an arbitrary position in the direction of the main shaft 10 from the groove 2 of the anvil. The arm member 4 for left and right positioning is a resin plate having a thickness of 0.5 to 2 mm, or
A metal plate was used. The tip is formed in an L-shape, and the other end is rotatably caulked on the back surface of the base 3 with a 3 mm-diameter aluminum rivet 5. A projection 6 is provided on the surface of the tip portion on the caulking side, and a click feeling is provided by the three recesses 7 provided on the back surface of the base 3. Made it easier. Note that the distal end portion of the arm member 4 may have a telescopic structure. At the time of staple binding, the depth positioning is performed by applying the end of the paper bundle to the V-shaped member 1, and the left and right positioning is performed by using the L at the tip of the arm member 4.
The end of the paper bundle may be applied to the character shape. Note that both the left and right positioning may be based on the scale line 8 attached to the arm member 4. FIG. 3 shows a rectangular member 9 which is an elastic body, instead of the V-shaped member 1, and is fixed in the longitudinal direction on the base 3 at a right angle to an arbitrary position in the direction of the main shaft 10 from the groove 2 of the anvil. is there. At the time of binding, the V-shaped member 1 or the square member 9 is pressed by the frame 11 to be deformed and fit into the gap between the frame 11 and the base 3, so that it does not become an obstacle during operation. When not in use, the frame 11 is pushed up by a spring (not shown), so that the V-shaped member 1, which is an elastic body,
Alternatively, the square member 9 is restored to its original shape and performs the function of a barrier. These mechanisms can also be applied to tabletop staplers.

[0007]

According to the present invention, staples can be stapled symmetrically and with a constant depth by simply pressing the end of the paper bundle against the V-shaped member and simultaneously pressing the L-shaped portion of the arm member to perform staple binding. The stapling can be performed quickly because the appearance is beautiful and the end of the paper bundle only needs to be applied to each member. If the length of the arm member is determined to be a length that does not interfere with the frequently used A4 size paper and B5 size paper even in the post-processing punch hole press, the arm member can be used in common and is extremely safe.

Further, even when it is desired to arbitrarily select the depth position, the V-shaped member has a spring property, so
Even if it overlaps with the character-shaped member, the operation is not hindered, and the conventional staple binding can be performed. Further, since there is no need to make a significant improvement to the conventional stapler, the production cost is low and the effect is extremely large.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stapler for stapling staples.

[0002]

2. Description of the Related Art Some conventional staplers are provided with a scale line provided on a base for depth alignment and a movable barrier when binding staples.

[0003]

These have the following disadvantages. Depth positioning when binding staples can be done with a graduation line on the base or with a movable barrier member.In these methods, the edge of the paper bundle is placed on the graduation line. It has to be adjusted every time and the position of the movable barrier member has to be adjusted, which is troublesome. The present invention has been made to eliminate these disadvantages.

[0004]

In order to determine the depth of staple binding, an elastic V-shaped member is placed on the base at a right angle from an arbitrary position in the main axis direction from the groove position of the anvil provided on the base. Was fixed and made a barrier at the end of the paper bundle.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION When positioning a staple at a constant depth, the end of a sheet bundle may be stapled to an elastic V-shaped member 1. When selecting an arbitrary depth position, there is no problem when binding at a position shorter than the fixed depth position, but when binding at a position deeper than the fixed depth position, paper is placed on the V-shaped member 1. The bundles will overlap. However, since the V-shaped member 1 requires elasticity, the shape of the V-shaped member 1 is deformed from the V-shape to the flat shape by being pushed by the paper bundle from above even if the paper bundle is overlaid. There is no problem in operation.

[0006]

FIG. 1 shows a case of a hand-type stapler according to an embodiment, in which a V-shaped member 1 formed of a resilient metal plate or a resin plate having a thickness of 0.1 to 0.5 mm. Is fixed on the base 4 at a right angle from an arbitrary position in the direction of the spindle 3 from the groove 2 of the anvil. In this embodiment, the V-shaped member 1 is fixed on the base 4 at a right angle to the main shaft 3 at a position 10 mm from the groove 2 of the anvil in the direction of the main shaft 3. When it is performed, binding with a depth of 10 mm can be performed. Assuming that the maximum number of sheets that can be bound is 20 and the thickness of the sheet bundle is about 1.6 mm, the height of the barrier portion of the V-shaped member is 2 mm. As described above, the height of the barrier portion of the V-shaped member may be determined based on the maximum number of sheets to be stapled by the stapler. FIG. 2 shows a rectangular member 5 which is an elastic body, instead of the V-shaped member 1, is fixed in a longitudinal direction on a base 4 at a right angle from an arbitrary position in a direction of a main shaft 3 from a groove 2 of an anvil. . The V-shaped member 1 or the square member 5 is deformed by being pushed by the frame 6 at the time of binding, and the frame 6 and the base 4
Into the gap (1 to 1.5 mm), so that there is no problem during operation. When not in use, the frame 6 is pushed up by a spring (not shown), so that the V-shaped member 1 or the angular member 5 which is an elastic body is restored to its original shape and functions as a barrier. These mechanisms can also be applied to tabletop staplers.

[0007]

According to the present invention, the staples are stapled by applying the end portions of the paper bundle to the V-shaped member, so that when a plurality of staples are stapled, the staples have a constant depth and are visually beautiful. In addition, the documents can be quickly bound because only the end of the sheet bundle needs to be applied to the V-shaped member. When choosing the depth position arbitrarily, the V-shaped member has elasticity,
Even if the paper bundle is superimposed on the V-shaped member, the operation is not hindered because the V-shaped member is in a flat state, and the document can be bound as before. Furthermore, since there is no need to make significant improvements to conventional staples, production costs are low,
The effect is extremely large.
