DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to (A) a paper binding device (stapler) used for a relatively thick pile of binding material, and a binding depth from an edge of a binding material. (B) the stopper is mounted on the bottom plate so as to be longitudinally shiftable, and (c) at the end of the magazine which serves to accommodate the binding means, The present invention relates to a type in which a protruding passage is provided.

2. Description of the Prior Art Known types of staples of this type make it possible to mechanically bind relatively thick bindings, for example 200 sheets of paper, without problems, using corresponding types of staples. . The inconvenience occurs only at the time of misbinding. This is because in this case the staples are still partially located in the protruding passage, which makes it impossible to continue to perform the binding in a prescribed manner. In contrast, in the prior art, in particular, means have been provided in which a spacer is inserted below the tilted magazine. When the lever of the paper binder is depressed, and thus the ejection cutter is depressed, the magazine is placed on this spacer, so that the staples caught in the ejection passage can be pushed downward without being hindered. All that is required in this case is that the height of the spacer is defined to correspond to at least one third of the length of each of the staple types to be used. The spacer as an additional component separate from such a staple must be prepared so that it is always at hand during use, which is not conceivable in actual use. Tokiko Sho 58-
In the case of a known stapler based on No. 48313,
A screw hole is formed in the bottom plate of the base, and a screw is screwed into the screw hole. In this case, the upper end of the screw protrudes from the bottom plate by a predetermined height in the direction of the holder for storing staples. By using such a known stapler, the object can be loosely loosened at the time of attaching a regular bill to textile goods or at the time of temporary sewing of clothes. However, such staplers are inconvenient for binding thicker stacks. This is because this known stapler is a small one that is operated by grasping the bottom plate and the top cover exclusively by hand, and the rear end of the screw protrudes downward from the bottom plate. This is because they cannot be placed on a flat table as in the case of the stapler used for binding. Furthermore, even when the staple can be pushed out using the screw when the staple is caught in the opening of the holder, the staple has to be adjusted by rotating the screw each time to the specified height. Can not be quickly and easily taken out. Rather, in the case of such a small stapler, it is easier to directly pull out the staple from the opening by hand. In addition, 5
In a known stapler based on Japanese Patent Application Laid-Open No. 6-14062, guide plates are provided on both left and right sides except for a central portion of a gauge body of a base, and these guide plates are each opened at 45 degrees toward the front. It has a corresponding inner side surface formed as a vertical corner guide surface and a front surface formed as a parallel guide surface, each being located in the same plane. Thereby, it is possible to reliably guide the object to be bound not only in parallel binding but also in corner binding. However, in order to bind a relatively thick pile, a guide surface having a height at least corresponding to the thickness is required,
Since the height of such a guide surface is different from the height required to push out the staples caught in the projecting passage of the magazine, the gauge body with the corner guide surface,
It cannot have a function for pushing out the stapled staples.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a paper binding device which can quickly and simply push out staples stuck in a projecting passage without additional auxiliary means. .

[0004]

In order to solve this problem, according to the structure of the present invention, a space for mounting a magazine is provided.
Stopper is brought under the magazine as a sensor
So that the respective mounting of the stop on the bottom plate
The stopper is pivotally supported about a point.
And as that.

[0005]

According to the present invention, the stapled staple can be ejected from the ejection passage very quickly. In this case, no special auxiliary means is required for this.

According to an advantageous embodiment of the invention, the stop is designed so that it is entirely or partially provided below the magazine as a spacer. This stopper is
The stopper can be pivotally supported about the respective bearing point. In this case, the stop is located below the magazine, which additionally serves as a spacer. Stopper is almost 45 °
It is advantageous if it is mounted so that it can only pivot in both directions.
In the pivot end position, a locking point for fixing the position may be assigned to the stopper.

In a further advantageous embodiment of the invention, each stop surface of the lever-shaped stop has a support surface which is stepped with respect to the surface of the stop. These support surfaces are arranged so as to face each other. Advantageously, the lower surface of the magazine can be mounted on each support surface of the stopper pivoted to the end position. In another advantageous embodiment of the invention, one side of each of the two-arm stops is
Abuts the magazine at the turning end position. Advantageously, the height of the support surface of the stopper corresponds to approximately one third of the length of the largest staple type to be used.

[0008] It is also possible for the stop to bear an element which can run under the magazine and serves as a spacer.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

In the known manner, a two-armed stopper 1 is guided in the center of the bottom plate 5 in a manner which allows it to be shifted longitudinally. The stopper 1 is mounted so as to be pivotable in both directions by approximately 45 ° about a respective center bearing point 2 of the stopper. At each pivot end position, a position-fixing part, for example a locking point, is assigned to the two-armed stopper 1. As can be seen from FIGS. 1 and 3, each stopper surface of the two-arm type stopper 1 has a support surface 3 stepped with respect to the surface. The lower surface of the magazine 4 can be placed on each support surface 3 of the two-arm type stopper 1 that has been turned to the end position. The projecting passage 6 located at the front end of the magazine 4 is located outside the range of the two-arm type stopper 1 (see FIG. 4). As can also be seen from FIG. 4, one side of the two-arm type stopper 1 is in contact with the magazine. The binding plate assigned to the protruding passage 6 is designated by the reference numeral 7.
