Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper bundle punching and binding device in which a cutting unit is provided behind the upper surface of a base and a slide base for placing a paper bundle on the base is slid between a punching position and a binding position. It is a thing.

[0002]

[Prior art]

 As an example, JP-A-62-218197 will be described below. A pillar is erected and fixed on the upper surface behind the base, and a handle is rotatably supported on the pillar. A piercing blade that moves up and down by the rotation of the handle is fixed inside the column. In addition, a document placing table is arranged on the upper surface of the base so that it can be moved back and forth, and a pressing plate is attached to the document placing table so as to be opened and closed by a stopper piece and a spring via a pressing shaft to press and fix the document. Has been.

Next, the operation will be described. First, the document to be punched is placed on the upper surface of the document placing table with the document placing table pulled out toward you. Next, the pressing plate is lowered and the pressing plate is locked and fixed by the stopper piece. The document is now fixed on the document table. Then, the document table is pushed in and the handle is rotated to punch the document. After finishing punching, pull out the punched document together with the document table and fasten the binding tool. Finally, the pressing plate was unlocked by returning the stopper piece, and the document was taken out.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, it is troublesome to operate the stopper pieces on the left and right while pressing the pressing plate to press the document. Further, since the pressing shaft for supporting the pressing plate is erected in the width direction, only the document having the width (length) between the pressing shafts can be pressed, and in the end, the size and direction of the document that can be punched. There was a problem that it was limited. The present invention aims to solve the above problems.

[0005]

[Means for Solving the Problems]

 The present invention is intended to solve the above-mentioned problems, and a cutting unit is arranged at the rear of the upper surface of the base so that a slide base for placing a sheet bundle on the base can slide between a punching position and a binding position. In this paper bundle punching and binding device, a paper bundle pressing member attachment plate is fixed to the rear of the slide base, and the paper bundle pressing member is attached to the paper bundle pressing member attachment plate so as to be vertically movable. It is what

[0006]

【Example】

 On the rear of the upper surface of the base 1, a side board 3 on which an elevating body 2 is vertically movable is vertically fixed. A push lever 4 for vertically moving the lifting body 2 is attached to the side plate 3 so as to be rotatable around a shaft 5. On the other hand, an elongate hole 6 is formed in the elevating body 2, and an engaging pin 7 fixed to the pressing lever 4 is fitted into the elongate hole 6. When the pressing lever 4 is rotated by the engagement between the elongated hole 6 and the engaging pin 7, the elevating body 2 can be moved up and down. A bracket for fixing a pressing unit, which will be described later, is fixed to the base 1 in the middle of the lifting body 2, and a cutting blade is detachably attached to the lower part of the lifting body 2 with screws or the like. There is. A slide base 8 on which a stack of paper is placed is mounted on the upper surface of the base 1 in a forward and backward sliding manner, and the rear end of the slide base 8 is arranged to align the rear ends of the stack of paper. It is formed in an L shape.

Further, although a pressing unit 10 for pressing the binding tool via a bracket or the like is attached to the rear of the base 1 by a screw or the like, the bracket may be integrally formed. Next, the pressing unit 10 will be described. On both sides of the pressing unit 10, pressing bars 12 and 13 that can be opened and closed by operating a lever 11 are arranged. The pressing rods 12 and 13 are urged upward by the elastic members 14 and 15 so as to be vertically movable.

Further, a paper pressing board mounting plate 16 is fixed to the rear of the slide base 8, and a paper pressing board 17 for pressing a sheet bundle is attached to the paper pressing board mounting plate 16 via a screw 18. ing. The screw 18 is screwed into the paper pressing board mounting plate 16, and is pivotally attached to the paper pressing board 17 in a rotatable manner. Therefore, the paper holding board 17 can be moved up and down with respect to the paper holding board mounting plate 16 by rotating the screw 18. The bottom surface 21a of the paper pressing board 17 is thinly coated with a rubber material or the like to prevent the paper bundle from slipping. Although the paper pressing board 17 is circular in this embodiment, it may be rectangular and the shape is not limited to the embodiment.

Next, the operation will be described. Before the stack of paper is placed on the slide base 8, the washer member 20 fitted to the binding pin 19 (see FIG. 2) is inserted into the recess 1a formed in the base 1. After inserting the washer member 20, the paper bundle is placed, the screw 18 is rotated, and the paper bundle is pressed by the paper pressing plate 17. Then, the slide base 8 is pushed in, and the pressing lever 4 is rotated to punch. After completion of punching, the sheet bundle is advanced together with the slide base 8. In this state, the binding pin 19 is inserted into the punched hole. Next, the lever 11 is moved to the left in the figure, and the pressing rods 12 and 13 are expanded to the left and right. By this expanding operation, the pressing rods 12 and 13 are located above the binding pin 19. Here, the pressing lever 4 is rotated again to lower the elevating body 2. Then, when the lifting body 2 is lowered, the protrusion 2a formed on the lifting body 2 presses the head portions of the pressing rods 12 and 13, and the binding pin 19 is fitted to the washer member 20. This completes the binding work. After the binding work is completed, the lever 11 is moved to the right and the pressing rods 12 and 13 are closed. Next, the screw 18 is loosened, and the bound paper bundle is removed from the punching machine. It should be noted that, during the above-mentioned binding work, since the sheet bundle has moved forward more than that at the time of punching, even if the punching blade moves down, the sheet bundle is not punched again.

FIG. 3 shows another example of the present invention. A through hole 22 having a notch portion 21 is formed at the tip of the paper pressing board mounting plate 16. A connecting rod 24 having a projecting piece 23 formed up to near the lower end 23a is slidably arranged in the through hole 22, and the connecting rod 24 is urged downward by an elastic member 25 and a knob 26 at the upper end. Is projected. Reference numeral 17 is a paper pressing board, which is rotatably attached to the lower end of the connecting rod 24.

Next, the operation will be described. Before placing the stack of sheets, the projection 23 is aligned with the notch 21, the knob 26 is gripped, and the connecting rod 24 is raised. The connecting rod 24 is slightly rotated at the highest position. By this operation, the protruding piece 23 separates from the notch portion 21 and engages with the edge of the through hole 22. With this, the paper pressing board 17 holds the raised position. The sheet bundle is placed in this state. After the mounting is completed, the projecting piece 23 of the connecting rod 24 is aligned with the notch 21 again. By this aligning operation, the connecting rod 24 descends due to the elastic action of the elastic member 25 and presses the sheet bundle. Subsequent operations are the same as those in the above-mentioned example, and the description thereof will be omitted.
