Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual stapler capable of performing a number of actual hits by loading a sheet needle.

[0002]

2. Description of the Related Art For example, in a conventional manual stapler described in Japanese Utility Model Publication No. 55-28457, a U-shaped needle formed in a separable series is configured to be loaded in a magazine. The driving of the U-shaped needle is
This is done by lowering the needle at the end of the U-shaped needle by the driver linked to the depression of the handle.After this driving, when the driver rises in conjunction with the rise of the handle, the U-shaped needle advances. Thus, the needle at the end is located so as to face the path of the driver. When a large number of needles are provided in the manual stapler, about three needles (one needle number is about 50, and about 150 needles) are loaded in series in a magazine. It is.

On the other hand, a conventional electronic stapler as described in, for example, Japanese Patent No. 2663799 and Japanese Patent No. 2666801 is mounted on a device such as a copying machine that handles paper, and a large amount of actual hits can be obtained. Format
A cartridge in which several tens of sheet needles each formed of a series of about 50 needles that can be separated are stacked and used in a magazine. The driving of the driving of the sheet needle and the stepping movement thereof are obtained by lifting and lowering of a driver by an electric motor and rotation of a masatsu roller which can be intermittently rotated in one direction, and the sheet needle located at the lowermost end of the cartridge is used. Before being exhausted, the next sheet staple is positioned in the guide path of the magazine so that the driving of the staple is continued. Further, the monitoring device attempts to position the leading end needle in the driver passage, which is necessary at the beginning of the loading of the cartridge, and to detect the lack of the needle in the cartridge.

[0004]

However, in the manual stapler, only about 200 needles can be equipped at a time in one loading, and in order to cope with a large number of actual hits, it is necessary to carry out the loading operation of the continuous needles. This would be repeated many times, and if four or more needles were loaded in series to reduce the number of loading operations, a longer magazine would be required. Also become large, making handling difficult. Further, in the manual stapler, since the handle is suddenly stopped after the completion of the driving of the needle, there is a problem that an impact due to the driving reaction force is applied to the hand.

On the other hand, the electronic stapler can perform a large amount of actual striking, but since the cartridge is composed of a plastic sealed container and a coil spring that is built in the sealed container and constantly pushes down the sheet needle, all the sheet needles are used. At the end of use, expensive cartridges are discarded, which is extremely uneconomical. Further, since a monitoring device for positioning the needles is provided, it is not possible to avoid high staple costs.

The present invention has been made in view of the above-mentioned problems of the conventional stapler, and makes use of the characteristics of a manual stapler, which is extremely convenient to handle, and is applicable to a cartridge in which sheet needles are stacked and stored. SUMMARY OF THE INVENTION It is an object of the present invention to provide a manual stapler capable of performing a large number of continuous actual hits by reducing the number of sheet needle loading operations.

It is another object of the present invention to provide a manual stapler using sheet needles, which can be used safely by alleviating an impact generated when operating a handle of the manual stapler.

Further, there is provided a manual stapler using a sheet needle in which a pressing member for pressing a sheet needle in a cartridge is moved out of the cartridge via an arm member which moves following an erecting operation of a handle. It is intended to do so.

A manual stapler that uses a sheet needle that adopts a means with a return spring hung over it, taking advantage of the characteristics of a manual stapler that is extremely convenient to handle,
This enables a large number of continuous hits. According to a second aspect of the present invention, a sheet needle is used which employs a means in which an elastic member having a tension greater than the tension of the return spring or a compression resistance is interposed between the link and the handle according to the first aspect. This is a manual stapler which solves the problem of the manual stapler, in which the handle suddenly stops after the completion of the driving of the needle, so that an impact due to the driving reaction force is applied to the hand. Further, according to a third aspect of the present invention, a handle, a magazine for loading a cartridge having an open top, a link including a driver plate and a forming plate, and the like are pivotally mounted on a base by a support shaft, and a seat in the cartridge is provided.
