[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a desk-top type office binding machine, and more particularly, it has been improved so that a desired plurality of sheets of a sheet bundle for office work can be simultaneously and neatly bound at once.

[0002]

[Prior art]

 The stapler for office use that has been commercially available in the past is, of course, not only the one-handed grip type, but also the large table-type staple (binding staple) that binds only one place of a sheet bundle. You can't.

In addition, regarding the so-called feeding margin of the sheet bundle, there is also a tabletop type in which a display scale for knowing this and a positioning stopper for the sheet bundle that moves according to the scale are attached to the base plate of the stapler. It can be seen, but it is still possible to bind only one place.

[0004]

[Problems to be solved by the device]

 Therefore, for example, when it is necessary to bind a large number of sheet bundles for distribution to a large number of people at schools, business establishments, neighborhood associations, etc., perform the manual work efficiently and lightly. I can't.

Also, in relation to various sizes such as A4 size and B4 size in the sheet bundle, since there is no index for guiding the binding position of each sheet, the binding points are not uniform. It may also interfere with the staples, such as in the case of subsequent punching operations.

[0006]

[Means for Solving the Problems]

 The present invention is intended to improve such a problem, and for that purpose, a smooth upper surface of the upper base is used for a set surface for a sheet bundle and a stapler with a constant opening band width slightly depressed from the set surface. By dividing into a concave step surface and notching a pair of front and rear groove rails facing the opening edge of the concave step surface, the entire concave step surface is shaped into a dovetail groove in side view. , A plurality of staplers having a mounting seat of a certain length that fits with both groove rails are slidably operated to the above dovetail-shaped concave step surface, and a sheet bundle placed on the above set surface. It is possible to close multiple staplers at the same time by fitting them together as a parallel state that can be eaten, and by horizontally connecting the connecting bar of the manually operated handle above the parallel staplers and pushing down the connecting bar. It is characterized in that it has set.

[0007]

[Action]

 According to the above configuration of the present invention, a plurality of staplers (S) that can be slid along the groove rails (13) are fitted into the stapler fitting concave step surface (b) of the base (F). Therefore, the plurality of staplers (S) can be simultaneously closed at a time by pushing down the manual operation handle (H), and the plural positions of the sheet bundle (M) can be bound, and the manual work can be performed efficiently. It can be done lightly.

Further, the plurality of staplers (S) are in a parallel state, and when they are regulated by the groove rail (13) of the recessed step surface (b) for fitting, they can slide accurately. Therefore, there is no risk that the plurality of binding points for the sheet bundle (M) will be misaligned, and the desired position can be freely bound by the sliding operation, which is extremely convenient.

【Example】

 The specific construction of the present invention will be described in detail below with reference to the illustrated embodiment. FIGS. 1 to 5 show a basic embodiment of the office binding machine. The base (F) that is used by being placed on the table surface, the plurality of staplers (S) that are slidably fitted into the base (F), and the plurality of staplers (S) are simultaneously pushed down and closed. It consists of an assembly with a manually operated handle (H).

First, the base (F) is made of a metal plate or the like into a quadrangle in a plan view, and its smooth upper surface has a set surface (a) for sheet bundles on the rear side and a stapler on the front side. It is divided into a concave step surface (b) for fitting. On the set surface (a) and the concave step surface (b), various sizes of paper, plastic film, and other sheet bundles (M), a display scale (11) for guiding the set position, and a display Indicators such as a frame (12) are attached.

The concave step surface (b) for fitting the stapler is recessed slightly lower than the set surface (a) for the sheet bundle, and the base plate (W) is maintained while maintaining a constant opening band width (W). It extends along the left-right direction of F). Reference numeral (13) denotes a groove rail which is formed by notching and opening a pair of front and rear faces facing each other at the opening edge of the concave step surface (b), whereby the entire concave step surface (b) is substantially a dovetail groove in side view. It is shaped in a mold.

In that case, one of the left and right ends of the base (F) is positioned by the positioning stopper (14) which stands slightly higher than the set surface (a) of the sheet bundle (M). Although the side edge of the sheet bundle (M) can be regulated to be positioned, such a positioning stopper (14) is not erected on the other end, and the sheet is in the open state. The stapler (S) can be slidably fitted into the dovetail-shaped concave step surface (b) from the other end of a certain base (F), and can also be pulled out. ing.

(15) is a screw receiving elongated hole which is provided along the opening front edge of the concave step surface (b) for fitting the stapler in parallel with the groove rail (13) in an opening row. A fixing screw (16) for positioning the stapler is inserted from above. Reference numeral (17) is also a feeding substitute adjusting bar that extends parallel to the groove rail (13) of the concave step surface (b). Although the figure shows a bent shape from a wire, its material and shape are An appropriate selection can be made as long as it does not hinder the operation of the stapler (S).

Reference numeral (18) is a pair of left and right adjusting slots for locking both ends of the adjusting bar (17), one of which is a positioning stopper (14) standing upright from one end of the stapler (S). ), Similarly, the other end is provided with an elongated opening in the front-rear direction at the other end of the base (F) itself. By sliding the adjusting bar (17) along the both adjustment elongated holes (18), the front edge portion of the sheet bundle (M) is positioned and regulated, and the stapler (M) is attached to the sheet bundle (M). The allowance (X) of S) (see Fig. 6) can be adjusted in size.

At that time, in order to prevent the inadvertent displacement of the adjusting bar (17), it is preferable to apply a spring pressure to both ends of the adjusting bar (17) from below the table (F). Reference numeral (19) is a display scale for guiding the adjustment position, which is engraved along each adjustment slot (18), but this is also engraved on the upper surface of the concave step surface (b). good. In addition, a recess (not shown) for receiving the adjusting bar (17) instead of such a display scale (19) is opened as a stepwise sawtooth shape continuous with each adjusting elongated hole (18). Is also possible.

As is apparent from FIGS. 3 to 5, the stapler (S) mentioned above has a constant length which is compatible with both groove rails (13) of the dovetail-shaped concave step surface (b) in the base (F). The mounting seat (20) of size (L) has a special form in which it is backed and integrated with the lower surface of the base plate (21). That is, the mounting seat (20) is formed to be slightly longer than the base plate (21) in the front-rear direction, and is slidable into the groove rail (13) of the concave step surface (b) at both ends of the protrusion. The projecting front end of the mounting seat (20) is pressed and fixed by the fixing screw (16) which is inserted into the above-mentioned screw receiving long hole (15). Reference numeral (22) is a screw receiving hole opened at the front end portion of the mounting seat (20), which is in communication with the screw receiving elongated hole (15).

However, instead of integrally attaching a separate mounting seat (20) to the base plate (21) of the stapler (S), the base plate (21) itself is fitted into the groove rail (13). Of course, it is also possible to form an overhang for a long time so that it can be inserted. Further, (23) is a receiving recess groove for the connecting bar cut out at a position offset to the rear end portion (free front end portion) of the cover handle (24) of the stapler (S). The connecting bar of the operation handle (H), which will be described later, is locked.

The rest of the structure of the stapler (S) is substantially the same as that of a known one-handed grip type, and if necessary, the base plate (21), the cover handle (24) and the staple (25) are accommodated. A magazine (26) and the like are rotatably pivoted from the rear end (free front end) by a horizontal fulcrum shaft (27) penetrating the front end (base end) thereof, and its cover handle. As soon as the downward ejector (28) is pushed down from (24), staples (25) in the magazine (26) are sequentially ejected one by one onto the anvil (29) of the base plate (21), The sheet bundle (M) that has been eaten between the magazine (26) and the base plate (21) in the upper and lower directions is independently separated by the staple (25). It is designed to be continuous. Reference numeral (30) is a pusher of the staple (25), and reference numeral (31) is a steady rest arm of the edge ejector (28).

In any case, in the present invention, a plurality of the staplers (S) are arranged side by side on the left and right sides, and are fitted into the concave step surface (b) for the stapler fitting of the base (F). In the state, as shown in FIGS. 1 to 3, the base plate (21) of the stapler (S) and the set surface (a) for the sheet bundle of the base (F) generate flat surfaces which are aligned with each other, and thus the stapler (21). The sheet bundle (M) can be smoothly and reliably fed into (S).

Further, the stepper (S) can be slid along the groove rail (13) according to various sizes of the sheet bundle (M) and the relationship with the set position, and the slide adjustment can be performed. It is also possible to position and fix the state by the fixing screw (16). That is, as is clear from FIG. 6, the mutual spacing (Y1) between the binding points by the plurality of staplers (S) and the mutual spacing (Y2) between each binding point and the side edge of the sheet bundle (M). Can be adjusted freely. At that time, a display scale for guiding the slide adjustment position of the stapler (S) and other indicators (not shown) are also used for the set surface (a) for the sheet bundle of the base (F) and the stapler fitting. It is desirable to give it to the concave step surface (b).

The manual operation handle (H) mentioned above is integrally formed with a connecting bar (32) that horizontally extends over a plurality of staplers (S) and from the central portion of the connecting bar (32) to the rear. The grip (33) consists of an overhanging grip (33), and the connecting bar (32) is stably locked in the receiving groove (23) cut out on the upper surface of the stapler (S), and the grip (33) is held with one hand. It is possible to simultaneously close multiple staplers (S) by holding and holding down and pressing down.

In this respect, in the basic embodiment shown in FIGS. 1 to 5, the manual operation handle (H) is separated from the base (F) and the stapler (S) fitted to the base (F) separately. However, the manual operation handle (H) may be assembled to the preliminary base (F) as is clear from the modified examples of FIGS. 7 and 8.

In FIGS. 7 and 8 showing the modified embodiment, (34) is a pair of left and right support pieces integrally erected from the front end of the base (F), and (35) is both support pieces thereof. It goes without saying that the support bars are fixedly laterally fixed between the pieces (34) and extend parallel to the groove rails (13) and the screw receiving slots (15). Reference numeral (36) is an opening / closing arm that is fixed and integrated in a state orthogonal to the connecting bar (32), and its front end (base end) is rotatably supported by the support bar (35). Similarly, a grip (33) is attached to the rear end (free front end). The opening / closing arm (36) can be slid along the support bar (35) in the left-right direction of the platform (F).

Therefore, by gripping the grip (33) and depressing the open / close arm (36) and the connecting bar (32) of the grip (33), a plurality of staplers (S) can be operated just as in the above-described basic embodiment. The sheets can be closed at the same time, and the sheet bundle (M) can be continuously bound. In that case, in the modified embodiment, the manually operated handle (H) is pre-assembled to the base (F) via the opening / closing arm (36) and the support bar (35), so that the basic embodiment described above is adopted. The cutout of the connecting bar receiving groove (23) for the cover handle (24) of the stapler (S) as described above may be omitted.

Since the remaining configuration of the modified embodiments of FIGS. 7 and 8 is substantially the same as that of the basic embodiment described above, only the corresponding reference numerals of FIGS. In any case, if the fixing screw (16) and the adjusting bar (17) are removed from the base (F) in the present invention, the detailed description thereof will be omitted. The stapler (S) can also be extracted from the concave step surface (b), and the extracted stapler (S) alone can be used as it is to bind a sheet bundle (M) in the same manner as a known product without any problem. You can do it.

[Effect of device]

 As described above, in the desk-top office binding machine according to the present invention, the smooth upper surface of the base (F) is slightly depressed from the set surface (a) for sheet bundles and a little from the set surface (a). By dividing into a concave step surface (b) for fitting a stapler with a constant opening band width (W) and notching a pair of front and rear groove rails (13) facing the opening edge of the concave step surface (b). While the entire concave step surface (b) is shaped into a dovetail groove in a side view, a step with a mounting seat (20) of a fixed length (L) that fits both groove rails (13) is formed. A plurality of pullers (S) can be slidably operated to the dovetail-shaped concave step surface (b), and the sheet bundle (M) placed on the set surface (a) can be eaten. It is fitted as a parallel state and a manual operation handle (H) is placed above the parallel stapler (S). Since the plurality of staplers (S) are closed at once at the same time by horizontally extending the connecting bar (32) and pushing down the connecting bar (32), the conventional technique described at the beginning. There is an effect that the above problem can be surely improved, and a large number of sheet bundles (M) can be bound in an orderly and efficient manner.
