[Industrial applications]

 The present invention relates to a stapler.

[0002]

[Prior art]

 The applicant of the present invention has developed a stapler which is convenient for storing and carrying the utility model registration Nos. 1948154 (Jpn. However, in these devices, after the lid is fully opened, the position of the needle-cutting tool is changed by sliding the movable lever having the needle-cutting tool provided on the inner side of the lid forward or backward with a fingertip. The troublesome means of switching between the use state and the non-use state was taken.

Further, when the lid body is held in a flat state in which it is held parallel to the substrate portion when not in use, a gap corresponding to the maximum thickness of the binding sheets can be formed between the lid body and the substrate. , The whole aesthetic was spoiled.

In addition, in the conventional stapler, since the thickness gap between the substrate and the lid body at the time of point-stapling is insufficient, the stapling needle ends in the state of being extended and is completely in the clinch state. Some of them were not able to (Fig. 12).

[0005]

[Problems to be solved by the device]

 Therefore, the present invention is a stapler that securely holds the lid in a flat state with respect to the substrate when not in use. After the lid is opened, it is pivoted to close the spindle at the base end of the lid and the substrate. The lid is automatically moved rearward by moving the slanted long hole to ensure smooth and easy switching from the unused state to the used state, and the gap for inserting the binding sheet is surely maintained. It is an object of the present invention to provide a stapler configured so that

[0006]

[Means for Solving the Problems]

 According to the present invention, an elongated hole having an inclined shape with an appropriate angle is provided at the base end portions of both left and right sides of a lid body which is covered by a needle body and can be opened and closed. Insert a supporting shaft projecting from the side plate, fix one end of the shrapnel to the rear end part of the needle pusher located inside the needle holder, and attach one end to the inner part of the lid. The other end of the pulling band pivotally attached to the other end of the needle pusher is pivotally attached to the other end of the needle pusher, and after the lid is opened, the slanted length is extended through the contracting machine and the pulling band. The fulcrum of the support shaft is moved within the hole, and the position of the needle cutting bit provided at the inner tip of the lid is moved to the inside of the front side of the needle body.

[0007]

[Action]

 When not in use, as shown in FIG. 2, the lid is in a flat state parallel to the substrate, but when returning from use, first install it on the outside of the left and right rear side plates of the substrate as shown in FIG. The lid is opened and rotated about the fulcrum. Then, since the lid pulls the pulling band, one end of the pulling band pulls the needle pusher and the needle pusher pulls the contractile ammunition, so that the lid keeps the tensioned state while fully opened. .

After the lid is fully opened with respect to the substrate, the lid is rotated so as to be closed again. Then, the contractile ammunition contracts and the needle pusher and the pulling band move forward, and at the same time, the lid is pulled by the contractile ammunition, and as shown in FIG. Since the support shaft that is inserted and pivoted in the position moves from the rear end to the front end, the lid body is positioned diagonally above the substrate. Therefore, in such a state, as shown in FIG. 5, the lid may be pressed with the thumb and used. The state immediately after pressurizing the lid is shown in FIG.

When the user wants to return to the unused state again, the lid is lifted from the state shown in FIG. 5, and the finger is used to move the lid slightly forward. Then, the position of the support shaft in the slanted elongated hole moves from the front end to the rear end, so that the fulcrum movement returns to the flat state as shown in FIG.

[Effect of device]

 In the stapler of the present invention, since the long holes at the left and right base ends of the cover plate are inclined long holes with a predetermined angle with respect to the support shaft protruding outward from the left and right base ends of the substrate, When the plate is opened and unfolded to change from the unused closed state to the used state and then closed and rotated, the position of the support shaft of the inclined long hole on the cover plate side automatically moves from the rear end to the front end. Therefore, it becomes possible to use it extremely smoothly and easily, and at the time of use, it is possible to secure the interval for inserting the binding sheet between the lid and the substrate for the maximum number of sheets. Therefore, it is possible to surely bind in a completely clinched state.

Therefore, it becomes very smooth that the lid plate slides back and forth with respect to the needle body to move the position of the needle cutting tool inward of the front side portion of the needle body, which is not smooth. It is possible to provide a convenient stapler in which the lid forms a flat state horizontally without opening a gap between the substrate and the lid when in use.
