[Operation] When a document to be bound is inserted into the main body from the lower front of the main body of the paper binder, the start switch is activated by pressing or detecting the paper, the motor rotates, and the cam rotates at the same time. The link plate to be fitted lowers the vertically moving part, and the pressing plate locked with the vertically moving part also descends, the punching needle perforates the paper, and at the same time, the horizontal axis presses the heads of the left and right staplers to move the paper. Bending, the motor further rotates, the vertical movement part finishes descending at bottom dead center and begins to rise, and the pressing plate also rises with the punching needle and the horizontal axis and stops when it is located near the top end of top dead center. When the switch is turned on, the motor stops and the documents are taken out, and then the documents can be bound in sequence. The punching needle of the punching portion of the present invention has a small number of upright standing with a diameter of around 1 mm, and when punching thick paper of around 50 sheets, it can be moved up and down with high accuracy to fit the female die and eliminate the punched rice. Requires a slide guide.

EXAMPLE A perforation portion for punching out numbers and characters formed by a series of small holes is provided in the center of the front surface of the frame body (1), and the perforation portion is provided on the front part of the holding plate (2) for punching. (3) is attached, a slide guide (4) is erected on the rear part, and a punching needle (6) is erected on the lower surface of the front part of the pressing plate (5) that fits and slides on the guide. The punching needle can be fitted into the punching hole (7) laid in the female mold, and the vertical moving part (8) is attached to the upper surface of the pressing plate, and the vertical moving part is installed inside the frame. The cam (10) rotates the worn motor (9).
A holding frame (12) is loosely fitted so as to move up and down via a link plate (11) that is loosely fitted to the horizontal axis (1).
3) was erected parallel to the front surface of the frame body, and staplers were arranged in rows on the left and right of the perforated portion so that the head of the stapler (14) was directly below the horizontal axis to form a paper binder. The slide guide is not limited to the fitting of the round bar and the round hole, and may be the fitting of a wedge-shaped groove and a protruding shape. Further, from a design point of view, the motor may have a shape in which the motor is attached to the frame sideways and a cam is attached via a gear. Further, when the electric stapler (15) is used in place of the manual stapler, it is not necessary to set the horizontal shaft upright from the vertical moving portion. Further, when it is necessary to imprint at the same time when binding documents, the printing plate (16) is attached to the front surface of the pressing plate, descends at the same time as punching, and imprints. The punching part is integrated with the holding plate and the female die, and it can withstand use even with the pressing plate and punching needle integrated, but due to cluttered use, the punching needle may be bent or damaged at the same time. If the mold is also damaged, it will be necessary to replace the holding plate, but it will be impossible to repair it outside the production plant. However, even if the holding plate and the female die are separate parts, and the pressing plate and the punching needle are separate parts, the holding plate and the pressing plate can slide with high accuracy, so that it is possible to easily use them only by replacing the damaged part.

[0007]

Since the present invention is often used on a desk such as an office, it is essential to have a small size and a light weight unlike a machine for a factory. In order to efficiently use a small motor, as an example, the output of the motor The rotation of the shaft is the same as the movement of the eccentric cam, and the vertical movement part is moved up and down via the link plate, so there is little waste of driving force and it can be used effectively as pressing force, so thick documents can be bound and punched tally marks can be created. I can do it. In addition, the punching needles in the punching part have many small diameters of about 1 mm and are erected upright. To punch thick paper, it must move up and down with precision and fit with the female die to remove the punching needles. By using a guide, even if a slight deviation occurs between the frame and the vertical movement part, the perforation part can move up and down without shifting to the front and back or left and right, so even documents with a thickness of about 50 sheets can be easily bound. Can be perforated. Note that the manual stapler can store only about 100 binding needles at a time, and the small stapler that can be arranged in the device of the present invention has a binding capacity of about 30 sheets. When binding documents, a manual stapler can be used instead of a manual stapler to accommodate about 1,000 binding needles at a time and bind about 50 sheets. Since 50 or more perforations can be perforated, the function can be effectively utilized. Further, when it is necessary to imprint at the same time when binding documents, a printing plate is attached to the front surface of the pressing plate, ink is applied or penetrated, and the printing is performed simultaneously with perforation to enable imprinting. The printing plate may be attached to the rotary drum and the drum may be rotated and stamped in conjunction with the punching process, but in both cases many steps can be performed in one step, which saves time and labor. .
