Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper-based moving mechanism in a stapler in which a magazine portion and a clincher portion are separated and arranged to face each other.
[0002]
[Prior art and its problems]
In general, when saddle-stitching a magazine or the like, a stapler in which a magazine portion and a clincher portion are separated from each other is used. When the printed paper passes between the magazine portion and the clincher portion, the stapler operates and is stapled.
[0003]
As shown in FIG. 6A, such a stapler is provided so that the magazine portion 1 can be moved vertically from the base plate 3 (however, the driving driver plate is fixed). A sheet reference 5 for aligning the level of the spelling sheet 15 with the height of the magazine section is disposed, and the clincher section 2 is disposed above the magazine section 1 so as to face each other. When the binding operation is performed, the sheet 15 is placed on the sheet reference 5 and the magazine unit 1 and the clincher unit 2 is driven downward. As a result, as shown in FIG. 5B, the magazine portion 1 is pushed down together with the paper 15, whereas the driver plate 8 moves relatively upward to drive the staples 6 in the magazine portion 1 upward. The paper 15 is penetrated. The leg portion of the staple hits the clincher portion 2 and is bent to complete the spelling.
[0004]
[Problems to be solved by the invention]
However, when the clincher unit 2 moves downward as described above, the paper 15 is also pushed downward, but since the paper reference 5 does not change, the paper 15 is bent and deformed. For this reason, it has been a cause of functional failures such as poor spelling based on floating binding and buckling.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a paper reference moving mechanism in a stapler that can effectively prevent the occurrence of inconveniences such as poor spelling by eliminating the above-described problems and making the paper reference movable. .
[0006]
[Means for Solving the Problems]
In order to solve the above-described problem, the paper-based moving mechanism in the stapler according to the present invention is a magazine unit in which a magazine storing staples is provided so as to be movable in the staple driving direction with respect to a driver unit having a staple driving driver plate. And the clincher portion that receives and bends the staples punched by the driver plate are separated from each other, and the magazine is pressed and moved by the clincher of the clincher portion, so that the relatively moved driver plate is placed in the magazine. In the stapler in which the staples are ejected toward the clincher, a paper reference for receiving the surface of the paper to be bound is disposed on the side of the magazine portion at a position substantially flush with the upper end surface of the magazine. Set the reference so that it moves together with the magazine. Characterized in that was.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of a magazine portion and a clincher portion of a separation-type stapler, FIG. 2 is a perspective view of the essential portion of the magazine portion, and FIG. 3 is a front view of the essential portion of the stapler. In the figure, reference numeral 1 denotes a magazine part, and 2 denotes a clincher part. Reference numeral 3 denotes a base plate. Inside the opening 4 formed in the base plate 3, a magazine portion 1 and a paper reference 5 are arranged.
[0008]
The magazine unit 1 includes a magazine 7 that stores a large number of staples 6 and a driver unit 9 that has a staple driving driver plate 8. The magazine 7 has a magazine body 11 mounted in an in-frame 10 and is formed with an ejection opening through which staples at the tip can be ejected upward. The in-frame 10 is attached to the base plate 3 so as to be movable in the staple driving direction (vertical direction), and a binding stand 12 is formed on the upper surface thereof. On the other hand, the driver unit 9 is fixed to the base plate 3. Therefore, the height position of the driver plate 8 provided in the driver unit 9 with respect to the base plate 3 does not change.
[0009]
On the other hand, the clincher part 2 is provided with the clincher holder 13 so as to be movable in the vertical direction, and a clincher groove is formed at the lower end of the clincher holder 13. The clincher portion 2 is fixed to an appropriate member and is opposed to the magazine portion 1 in a state of being vertically separated. The clincher unit 2 is provided with a driving device 14 that moves the clincher holder 13 up and down.
[0010]
Next, the sheet reference 5 receives the surface of the sheet 15 to be bound, is formed in a box shape, and is normally positioned so as to be substantially flush with the binding stand 12 of the magazine 1, and the opening 4 of the base plate 3. Is arranged to be movable up and down. The paper reference 5 is attached to the in-frame 10 so as to be interlocked with the in-frame 10 of the magazine section 1. A compression spring 16 is disposed between the paper reference 5 and the base plate 3, and the paper reference 5 is biased so as to be positioned at the upper moving end.
[0011]
When binding paper with the stapler having the above-described configuration, first, the staple paper 15 is inserted between the magazine portion 1 and the clincher portion 2 as shown in FIGS. When the driving device of the clincher unit 2 is operated, the clincher holder 13 is driven downward and presses the magazine unit 1 together with the sheets 15 to be bound. The magazine portion 1 also moves downward. At this time, the driver plate 8 of the driver unit remains fixed, so that the driver plate 8 moves relatively with respect to the magazine portion 1. As a result, the driver plate 8 drives the leading staple 6 in the magazine 7 upward. The leg portion of the staple 6 that has been punched out penetrates the stapled paper 15 and hits the clincher groove at the lower end of the clincher holder 13, and is bent here to complete the spelling of the stapled paper 15. This state is shown in FIGS. When the clincher holder 13 is moved upward after the end of the binding, the interval between the magazine portion 1 and the clincher portion 2 is widened, so that the binding paper 15 can be moved along the base plate 3. When the bound paper 15 runs out, the magazine 1 and the paper reference 5 are raised to the initial position by the compression spring 16.
[0012]
By the way, when the clincher holder 13 presses the binding paper 15 downward as described above, the magazine unit 1 also moves downward, so that the paper reference 5 provided integrally with the in-frame 10 also moves downward by the same amount. To do. As described above, since the magazine unit 1 and the paper reference 5 are moved in the same direction by the same amount, the bound paper 15 is not deformed during the binding operation.
[0013]
As described above, since the paper reference 5 can be moved together with the magazine unit 1, it is possible to effectively prevent a functional failure such as a spelling failure.
[0014]
Note that the sheet reference 5 only needs to sink integrally in response to the downward movement of the magazine unit 1, and does not necessarily move together with the magazine unit 1. For example, the paper reference 5 may be provided on the base plate 3 so as to be movable up and down, and may be urged so as to be positioned upward by a spring. Also in this case, since the sheet reference 5 is moved downward against the spring in response to the sheet 15 being pressed downward during the binding operation, the sheet 15 is not deformed. Note that the term “integral” means that the magazine unit and the paper reference are moved together or at substantially the same timing by substantially the same amount of movement.
[0015]
【The invention's effect】
According to the first aspect of the present invention, the paper reference for receiving the surface of the paper to be bound is arranged at a position substantially flush with the upper end surface of the magazine, and the paper reference is provided so as to move integrally with the magazine. Therefore, the bound paper is not deformed during the binding operation. Therefore, it is possible to effectively prevent the occurrence of functional trouble such as poor spelling.
