Then, from the state of FIG. 3 in which the holding piece 51 usually attached to the spine width adjusting portion 1 on the front cover A side is detached from the base portion 52 and the pipe 53 and the shaft 54 are dissociated, the pipe 53 and the shaft 54 are removed. After that, by attaching both pressing pieces 51 to the base portion 52 so as to face each other, as shown in FIG. 3 → FIG. 14 or FIG. 9 → FIG. The binding rod 5x having a fitting depth corresponding to the contact / separation position is formed.

In the above configuration, the present embodiment is provided with the fixture 6 that fixes the spine width adjusting portions 1 and 2 at a predetermined spine width position.

As shown in FIGS. 2, 4, 6, and the like, the fixture 6 is a plate-like member that is rotatably connected to the edge of the cover plate 42 of the mounting mechanism 4 via a hinge portion 6 a. The lower surface has protrusions 61 and 62, and an attachment claw 61 a that can engage with the inner step portion 32 a of the attachment hole 32 of the back plate 3 is formed at the tip of the protrusion 61. That is, since the cover plate 42 of the attachment mechanism 4 is always disposed at a fixed position with respect to the back plate 3, the fixture 6 is always attached to a predetermined attachment position on the inner surface of the back plate 3. The protrusion 61 is provided with flexural elasticity in a direction away from the hinge portion 6a when the attachment claw 61a is engaged or detached, and the protrusion 62 has a strength that substantially regulates the positional deviation of the back width adjusting portions 1 and 2. have.

That is, the back width adjusting portions 1 and 2 are contracted to the minimum back width position shown in FIGS. 3 to 5 and 8, and the attachment claws 61a of the protrusion 61 are engaged with the attachment holes 32 of the back plate 3 shown in FIG. 4 and 6 to 8, the protrusions 61 and 62 are inserted into the through-hole 12 (22) of the back width adjusting portion 1 (2), and the back width adjusting portion 1 (2) is inserted. On the contrary, the back width adjusting portions 1 and 2 are widened to the maximum back width position shown in FIGS. 9 to 11, and the mounting claws 61a of the protrusion 61 are attached to the back plate 3 shown in FIG.

The fixture 6 is click-stopped to the position shown in FIG. 6 which has been moved from the engagement position to the non-engagement position by the hinge portion 6 a, and is held upright with respect to the cover plate 42.

By the way, if it is the above configuration, in the widened state, the shaft 54 constituting the binding rod 5x of the binding tool 5 is pulled out from the pipe 53 by the widened dimension as shown in FIGS. Then, the step formed between the pipe 53 and the shaft 54 becomes a catch when the paper sheet is passed during browsing, and not only is the strength insufficient, but the holding piece on the side where the shaft 54 is attached. When the paper 51 is removed and the paper sheets are added and removed, if there are many paper sheets that are bound, there is a possibility that the paper sheets may come off and scatter due to insufficient pipe length.

Therefore, in the present embodiment, as shown in FIGS. 3 and 9, a storage space S is provided at a position that opens and closes as the back width is adjusted, and the extension pipe 55 is stored in the storage space S to widen the back width. In this case, the storage space S is opened so that the extension pipe 55 can be taken out. Then, by fitting the extension pipe 55 to the existing pipe 53, the binding rod 5x can be extended while the shaft 54 protruding from the existing pipe 53 is covered with the extension pipe 55 as shown in FIG.

The storage space S is formed between the base portion 52 and the inner surface of the back plate 3, and the base portion 52 originally has a central portion raised due to the formation of a mechanism portion such as a bearing 52a on the outer edge side. It is a hollow portion 52x. Accordingly, the hollow portion 52a is used to form the concave portion 34 on the inner surface of the corresponding back plate 3, and the portion corresponding to the concave portion 34 is cut out of the inner edges 1p, 2p of the back width adjusting portions 1, 2 (see FIG. 9, a gap functioning as the storage space S is secured between the hollow portion 52 x and the concave portion 34. A holding piece 34a for engaging the extension pipe 55 stands up in the recess 34, and the extension pipe 55 can be fitted and held in the holding piece 34a as shown in FIG. Of course, when the inner edges of the left and right base portions 52 are brought into contact with each other in this state, the base portion 52 can cover the upper portion of the storage space S without interfering with the extension pipe 55.

On the other hand, as shown in FIG. 18, the extension pipe 55 is formed by plastically deforming a thin steel plate made of stainless steel or the like into a cylindrical shape and elastically deforming in the radial direction while opening the edges extending in the longitudinal direction. Thus, as shown in FIGS. 16 and 18, it is longer than the existing pipe 53 by a width-enhancing dimension and is slightly larger in diameter, and is externally fitted to the existing pipe 53 while elastically expanding in the radial direction. It is set as follows.

Then, in the vicinity of the holding piece side end portion of the existing pipe 53, an uneven portion 53a that is concave outward as shown in FIGS. 9, 18, and 19A is provided, and a fitting that is a corresponding portion of the extension pipe 55 is provided. An unevenness-related portion 55a that protrudes inward on the starting end side is provided, and a deformation inducing portion 55b having a partial waveform is formed in the vicinity of the unevenness-related portion 55a of the extension pipe 55, and the unevenness-related portion is formed by the deformation inducing portion 55b. The elastic deformation in the radial direction of the portion 55a and its peripheral portion is induced.

Further, as shown in FIGS. 16, 18 and 19 (b), a narrowed portion for narrowing the inner diameter of the extension pipe 55 is formed in an extension portion of the extension pipe 55 shown in FIG. A plurality of inwardly extending ridges 55c extending along the longitudinal direction of the extension pipe 55 are provided in the outer peripheral equiangular position by driving.

  In the present embodiment configured as described above, a pair of spine width adjusting units 1 and 2 are provided on the inner edges of the front cover A and the back cover B, and the spine width adjusting units 1 and 2 are arranged in the contact / separation direction. A different back width position is obtained by slidably arranging the back plate 3 along the back. Then, the fixture 6 can be attached to a predetermined attachment position on the inner surface side of the back plate 3, and the protrusions 61 and 62 which are related portions set to a part of the fixture 6 along with the attachment are provided on one of the back width adjusting portions 1 and 2. The inner edge 1p which is one of the related parts at the widened position is obtained by engaging with the through parts 12 and 22 or the inner edges 1p and 2p which are set as the related parts, and providing the related parts in a plurality of places in this way. 2p is involved in the engagement, and the penetrating parts 12 and 22 which are the other related parts in the narrow position are involved in the engagement.

With this configuration, the spine width adjusting units 1 and 2 can be used by re-fixing from the narrow position, which is the normal position, to the widened position. The amount of binding can be made variable effectively. Also, even when a large number of paper sheets are to be bound in advance, if the back width adjusting units 1 and 2 are adjusted to a narrow position while the amount of binding is small, many dead places are stored in storage places such as shelves. It is possible to effectively eliminate the generation of space. In addition, since the fixture 6 is fixed at a fixed mounting position from the inner surface side of the back plate 3, the back width can be easily changed and fixed in a spread state on the desk, and the back plate 3 is more than necessary. It is also possible to effectively improve the processing convenience and the like.

Specifically, after restricting the movable range of the back width adjusting portions 1 and 2 with respect to the back plate 3, the protrusions 61 and 62 provided on the fixture 6 are used as a common related portion, while the back width adjusting portion 1 and The inner edges 1p and 2p of the two and the through portions 12 and 22 provided in the vicinity of the inner edges 1p and 2p are related parts, respectively, and the protrusions 61 and 62 of the fixture 6 are connected to the back width adjusting parts 1 and 2 at the maximum back width position. The protrusions 61 and 62 of the fixture 6 are engaged with the through-holes 12 and 22 of the back width adjusting portions 1 and 2 at the minimum back width position in association with the inner edges 1p and 2p. In this way, by using the inner edges 1p and 2p of the back width adjusting portions 1 and 2, the number of the through portions 12 and 22 provided in at least the back width adjusting portions 1 and 2 can be reduced. Since 2 is relatively narrow, it can be employed as a particularly effective configuration when there are circumstances in which a large number of through portions cannot be provided along the sliding direction.

Further, the fixture 6 is attached to the back plate 3 so as not to interfere with the sliding operation of the back width adjusting portions 1 and 2 and cannot be detached from the back plate 3, and the back plate 3 is kept in a predetermined state while maintaining the attached state. Since the attachment / detachment to the attachment position is possible, the fixture 6 is always attached to the back plate 3, and the operation of attaching the fixture 6 to the fixed attachment position of the back plate 3 is effectively performed by anyone. be able to.

Specifically, between the back width adjusting portions 1 and 2 and the back plate 3, the back width adjusting portions 1 and 2 are attached to the back plate 3 with the support rod 41 penetrating the back width adjusting portions 1 and 2. Since the attachment mechanism 4 is mounted so as not to be detached and the fixing tool 6 is supported on one end side of the support rod 41, the fixing tool 6 can be reliably attached to the back plate 3 via the support rod 41. The structure can be kept simple.

The attachment mechanism 4 also has a cover plate 42 that is disposed to face the back plate 3 at a predetermined distance on one end side of the support rod 41, and the fixing plate 6 is movably supported by the cover plate 42 and related. Since the projections 61 and 62 that are the parts are detached from the through parts 12 and 22 that are the related parts and the inner edges 1p and 2p, it is possible to prevent the back width adjusting parts 1 and 2 from being detached from the support rod 41. At the same time it can be prohibited by the plate 42, the attachment destination of the fixture 6 can be easily secured on the cover plate 42.

In particular, since the fixture 6 is rotatably supported by the cover plate 42 via the hinge portion 6a, it is possible to effectively prevent dropping and loss from the cover plate while maintaining good operability through a rotational operation with little shaking. In addition, when moving from the attachment position to the removal position, the hinge portion 6a is click-stopped. Can be performed effectively.

Further, the attachment mechanism 4 is engaged with the long holes 42a and 31 that serve as the guide portion of the support rod 41, and the movement of the back width adjusting portions 1 and 2 with respect to the back plate 3 by the support rod 41 and the long holes 42a and 31. Therefore, it is possible to smoothly slide the back width adjusting portions 1 and 2 using the support structure of the fixture 6 without providing a separate slide guide portion, It becomes possible to effectively avoid complication.

Furthermore, an attachment claw 61a is provided at the tip of the projection 61 which is a related portion, and an attachment hole 32 is provided at a predetermined position of the back plate 3, and the projection 61 is connected to the inner edges 1p and 2p which are related portions and the through portions 12 and 22. As a result, the mounting claw 61a is hooked on the mounting hole 32 so that the projection 61 is held at the required engagement position. It can be used as an attachment member attached to the plate 3. For this reason, the simplification of the structure can be achieved, and the back width fixing operation for engaging the protrusion 61 with the through portions 12 and 22 and the inner edges 1p and 2p is directly connected to the mounting operation of the fixture 6. The stool for changing the back width can be effectively improved by a series of operations.

In the above, the binding tool 5 attached to the file F of the present embodiment is configured such that the pair of pressing pieces 51 can be attached to and detached from the corresponding back width adjusting parts via the base portion 52, respectively. And a pipe structure that forms a binding rod having a fitting depth according to the back width by fitting a shaft 54 protruding from one of these pressing pieces 51 and a pipe 53 protruding from the other, The base portion 52 of the binding tool 5 has the same configuration as that obtained by halving the base portion of the binding tool that constitutes a file having a constant back width. For this reason, when the back width is adjusted narrowly, it can be handled with the same back width and the same binding amount as a file using a normal binding tool, which is convenient for handling and easy to make a binding tool. Become a thing.

The specific configuration of each unit is not limited to the above-described embodiment.

  For example, when the spine width adjusting portions 1 and 2 are wide to some extent, as shown in FIG. 20, the protrusions 61 and 62 provided on the fixture 6 are used as a common related portion. A plurality of penetrating parts 112 and 122 may be provided in the adjusting parts 1 and 2 as related parts, and the protrusions 61 and 62 may be selectively engaged with the penetrating parts 112 and 122 under the same conditions. .

Alternatively, when the movable range of the back width adjusting portions 1 and 2 with respect to the back plate 3 is restricted, as shown in FIG. 21, the outer end of the fixture 106 at the maximum back width position (FIG. 21A). 106a is used as a related portion, and the inner edges 1p and 2p of the back width adjusting portions 1 and 2 are formed as related portions with which the outer end 106a is engaged, and the fixing device 6 is positioned at the minimum back width position (FIG. 5B). The protrusion 161 provided inward from the outer end 106a is used as a related part, and the through holes 212 and 222 provided near the inner edges of the back width adjusting parts 1 and 2 are used as related parts with which the protrusion 161 is engaged. Also good. In this way, even if the penetration parts 212 and 222 are provided at positions close to the inner edges 1p and 2p of the back width adjusting parts 1 and 2, the back width adjusting parts 1 and 2 are fixed under a relatively large back width change. can do.
