Description

  The present invention relates to a sheet processing apparatus for performing processing such as forming holes in a sheet.

  Conventionally, a sheet processing apparatus such as a punch (see, for example, Patent Document 1) for forming a hole for binding on a sheet and a binding machine (for example, see Patent Document 2) capable of binding a plurality of sheets of paper is known. It is done.

  Among the above-described sheet processing apparatuses, focusing on the punch as an example, the conventional one has a gauge supported so as to be able to protrude and retract with respect to the punch main body having the sheet receiving surface in order to position the sheet. There is. The gauge is provided with a stopper for bringing the edge of the sheet into contact with the leading end, and the position of the stand is adjusted by projecting and retracting the entire gauge with respect to the punch body. It serves to position the paper. In particular, in the case of Patent Document 1, the stopper is configured to be operable with respect to the gauge so that the stopper can be erected from the gauge only in use.

  However, in such a case, the stopper is accommodated in a state where it does not stand up with respect to the punch main body so that the gauge projects and sinks relative to the punch main body. That is, the sheet can not be positioned in the posture in which the stopper is accommodated in the punch body. Therefore, the user must always adjust the position of the stopper to a predetermined position every time it is used. In other words, in the past, without exception, in addition to the operation for setting the gauge to the desired position, the position of the stopper is adjusted to the position where it can abut on the edge of the paper at the minimum. Multiple actions are required. As a result, the use of the gauge itself has given the user the impression of being cumbersome. Furthermore, even when the gauge is not used, when the stopper is in the upright state, the stopper interferes with the sheet, which may impair the workability. In other words, in the conventional gauge, in addition to the operation of operating the gauge, a special operation for making the gauge usable has been required. And such a special operation has a risk of giving the user the impression that the handling of the gauge is complicated.

  Such a gauge is, of course, not only applied to a punch, but also applies to, for example, a binding machine or a stapler, the same problem occurs. That is, when applied to a sheet processing apparatus with conventional gauges, it has become possible to cause the above-mentioned problems without exception.

Unexamined-Japanese-Patent No. 2011-224691 JP, 2010-137551, A

  The present invention focuses on such a problem, and an object of the present invention is to provide a sheet processing apparatus in which at least an operation for reliably setting a gauge at a desired position can be easily performed.

  The present invention takes the following measures to achieve such an object.

That is, a sheet processing apparatus according to the present invention includes an apparatus body having a sheet placement surface, a processing mechanism for processing sheets provided on the apparatus body and placed on the sheet placement surface, and the apparatus body A sheet processing apparatus, comprising: a gauge slidably provided between a storage position and a use position and positioning a sheet to be placed on the sheet placement surface at the use position, the apparatus body comprising: It is premised that a gauge raising and lowering mechanism is provided to raise and lower the gauge during sliding movement of the gauge.

  Here, "raising and lowering the gauge" is not limited to only the one in which the entire gauge performs the raising and lowering operation. That is, as long as the slide operation is used, the elevation operation of the entire gauge may be performed, or the elevation operation of only a specific part of the gauge may be performed. Here, as an example of the raising and lowering operation of only a specific part of the gauge, there is a mode in which the stopper provided integrally or separately with the gauge rotates while the upper end position of the stopper changes while rotating. In addition, for example, the upper end of the stopper which is a part of the gauge itself is moved up and down by a sliding operation accompanied by a reciprocating operation that the stopper which is a part of the gauge rises from a folded state and falls back from an upright state. It is a concept that also includes action. Of course, it is needless to say that the above-mentioned partial rotation and raising / falling movement of the gauge may be performed together with the raising and lowering of the entire gauge. In addition, the gauge raising and lowering mechanism according to the present invention is a concept including a mode in which the gauge does not have a stopper but ascends and descends to a position which easily acts on the sheet in the use position.

  If it is such a thing, it can be set as a use position required for a user by raising / lowering a gauge naturally, if it slides by a gauge raising / lowering mechanism. As a result, the user only needs to perform the sliding operation when using the gauge. That is, according to the present invention, it is possible to provide a sheet processing apparatus in which at least an operation for reliably setting a gauge at a desired position can be easily performed.

As a specific configuration of a gauge elevating mechanism which easily processes a sheet in the use position, the gauge is provided at a gauge main body slidably supported by the apparatus main body, and at an outer end of the gauge main body are those in which a stopper for engaging the edges of the paper, the use with the gauge lifting mechanism, the upper end of the stopper before Symbol storage position is located below or substantially flush than the sheet stacking surface the upper end of the stopper that has become a raising and lowering the gage to be positioned above the said sheet stacking surface at the position. In such a case, the upper end of the stopper is positioned flush with or lower than the sheet mounting surface at the storage position, and the gauge is in a suitable position and orientation that does not interfere with the sheet. Can be stored.

As an effective configuration for stabilizing the slide movement of the gauge, the apparatus main body includes a base having the sheet mounting surface, and a receiving bottom mounted on the lower surface side of the base. The receiving portion is provided with a gauge holding portion provided with a bottom surface supporting the gauge main body from the lower side and a guiding side surface guiding the gauge main body from the side.

  Further, in order to make the accurate slide movement of the gauge and the raising and lowering motion by the gauge raising and lowering mechanism compatible with a simple configuration, the gauge main body has a shape in which the upper and lower thickness dimensions gradually decrease from the inner end to the outer end. Preferably, only the lower surface of the inner end portion is in sliding contact with the bottom surface of the gauge holding portion at all times. According to such a configuration, specifically, the movement of the gage elevating mechanism can be realized by raising and lowering only the outer end of the gage.

Since the gauge lifting mechanism raises and lowers the gauge main body by the slide cam mechanism provided between the apparatus main body and the gauge main body, both accurate positioning of the sheet by the gauge and reliable lifting and lowering are achieved. can do.

  Then, as a specific configuration for achieving stable operation of the gauge, the slide cam mechanism is positioned on the lower rail projecting from the side surface of the gauge main body, and on the inner end side of the lower rail. And a lower guide surface for projecting the gauge main body in the lowering direction by being engaged with the upper rail projected on the side surface of the gauge main body and the inner end of the lower rail projecting on the inner side surface of the gauge holding portion And an outer end of the upper rail, a guide projection having an upper guide surface for guiding the gauge main body in the upward direction.

  In addition, in order to realize the further simplification of the configuration of the gauge, it is preferable that the gauge be formed integrally with the gauge body and the stopper.

  The present invention can be suitably applied to the processing mechanism for forming a hole in a sheet.

  According to the present invention, it is possible to provide a sheet processing apparatus that can be easily operated to set at least the gauge at a desired position.

That is, the punching mechanism 2 corresponds to a processing mechanism according to the present invention for processing a sheet. In addition, since the perforation | punching mechanism 2 is a known structure, detailed description is abbreviate | omitted.

  Here, in the punch A according to the present embodiment, the gauge G is provided at the gauge main body 3 slidably supported by the punch main body 1 and at the outer end of the gauge main body 3 to lock the edge of the sheet. It has the stopper 4 and is characterized in that a gauge lifting and lowering mechanism X for lifting and lowering the gauge G using the sliding motion of the gauge G is provided. Specifically, in the punch main body 1, the upper end 4a of the stopper 4 is located below the sheet placement surface M at the storage position (s) and the upper end 4a of the stopper 4 from the sheet placement surface M at the guide position (g) The gauge elevating mechanism X is provided to raise and lower the gauge G by using the sliding motion of the gauge G so as to be positioned on the upper side.

  The configuration of the gauge holding portion 5 and the configuration of the gauge G in the receiving bottom U will be described below.

  The receiving base U is detachably attached to the lower surface side of the base B with respect to the punch main body 1, and is made of resin. The receiving base U has a gauge holding portion 5 for supporting the gauge G on one side thereof. The receiving base U is provided with a receiving base body u1 having a lid function for closing the lower opening m of the base B, and a gauge holding part projecting outward from the right side edge of the receiving base body u1 in plan view It is equipped with five.

  The receiving main body u1 has a substantially rectangular shape in a plan view, and the lower surface can be attached to the mounting surface M such as a top plate of furniture. The receiving body u1 includes a bottom wall s1, front and rear walls s2 and s3 extending upward from the peripheral portion of the bottom wall s1, and left and right side walls s4 and s5, in a space surrounded by these. A gauge holding portion 5 is disposed while accommodating the scum that is formed when the sheet is punched. The rear corner portion of the receiving bottom body u1 can be partially opened and closed via the hinge portion 15 provided on the bottom wall s1 to improve the convenience in discarding the escape debris. On upper surface portions of the left and right side walls s4 and s5, there are provided a sheet receiving surface 17 for receiving the sheet, and a locking wall 18 for positioning the end of the sheet together with the locking wall 12. That is, in the present embodiment, the sheet placement surface M is configured together with the sheet receiving surface 11 and the sheet receiving surface 11 provided in the receiving main body u1. In the vicinity of the sheet receiving surface 17 and the locking wall 18 in the left side wall s4, a stopper accommodating portion 19 for accommodating the stopper 4 of the gauge G at the accommodating position (s) is provided.

  The gauge holding portion 5 is located on the front side of the receiving base body u1. The gauge holding portion 5 includes a bottom surface 51 supporting the gauge main body 3 from the lower side, and a guiding side surface 52 guiding the gauge main body 3 from the side. The bottom surface 51 has a plurality of recessed portions 56 for positioning the gauge 3 by engaging with the gauge main body 3 and a flat surface formed between the plurality of recessed portions 56 to make the gauge main body 3 slide. doing. The guide side surface 52 has a guide ridge 53 formed to project from both front and rear sides in the vicinity of the outer end. The guide ridges 53 have an inclined shape while curving upward from the inner end to the outer end in a front view. In the present embodiment, when the upper surface of the guide projection 53 is engaged with the gauge main body 3, the upper guide surface 54 guides the gauge main body 3 in the upward direction. The lower surface of the guide projection 53 serves as a lower guide surface 55 for guiding the gauge main body 3 in the lowering direction when engaging with the gauge main body 3. The specific relation between the upper guide surface 54 and the lower guide surface 55 and the gauge body 3 will be described in detail later.

  The gauge G performs positioning of the sheet with respect to the punch main body 1 in order to determine the position of the hole formed in the sheet. The gauge G slides between a position where the sheet can be positioned, ie, a guide position (g) projecting outward from the punch body 1 to a storage position (s) arranged along the punch body 1. And a stopper 4 provided movably with respect to the gauge main body 3 and guiding an end of the sheet at a guide position (g). The gauge G is made of resin in which the gauge main body 3 and the stopper 4 are integrally formed.

  The gauge main body 3 is an elongated block, and the sheet support surface 31 constituting the upper surface is set to be positioned slightly below the sheet receiving surface 11 of the punch main body 1 at the guide position (g). . Further, the sheet support surface 31 of the gauge main body 3 is always set at a constant height position with respect to the sheet receiving surface 11 regardless of the relative position with the punch main body 1 at the guide position (g). . Note that on the sheet supporting surface 31, a scale for guiding in accordance with the sheet size may be displayed. Further, the gauge main body 3 is positioned on a lower rail 33 protruding from a part of the edge of the outer end on the side surface side and substantially in the left-right direction on the inner end side of the lower rail 33 And an upper rail 32 projecting from the upper end of the side surface. And in this embodiment, the gauge main body 3 forms the taper surface 34 over the lower whole area so that it may have a shape in which the upper and lower thickness dimension gradually decreases from the inward end to the outward end. In addition, only the lower surface of the inward end portion is slightly protruded to form the sliding contact convex portion 36, and the sliding contact convex portion 36 is always in contact with the bottom surface 51 of the gauge holding portion 5. Specifically, by providing two notches 35 in the front and rear direction in the vicinity of the sliding contact convex portion 36 and using the region between the notches 35 as the elastically deformable portion 37, the sliding contact convex portion 36 is a bottom surface 51 of the gauge holding portion 5. The sliding contact is always in the state of accumulated elastic repulsive force.

  The stopper 4 is formed so as to be substantially flush with the contact surface 41 which is an inner surface erected to be able to abut the end of the sheet and the right side wall of the receiving bottom body u1 at the storage position (s) And an outer surface 42. The stopper 4 is accommodated in the stopper accommodating portion 19 of the receiving body u1 at the accommodation position (s), and is positioned such that the upper end 4a is equal to or smaller than the sheet receiving surface 17.

  The punch A is provided between the gauge main body 3 and the punch main body 1 with a moderation mechanism for making the gauge body 3 modestly stop (click stop). Specifically, the moderation mechanism is a moderation of the gauge main body 3 with the punch body 1 at a plurality of positions at the storage position (s) and the guide position (g), specifically at a plurality of positions corresponding to a predetermined sheet size. It is made to stop (click stop). Specifically, on the bottom surface 51 of the gauge holding unit 5, the sheet sizes conforming to the predetermined standards such as A4 and B5 generally used at the storage position (s) and the guide position (g) are used. The position of the concave portion 56 is set such that the sliding contact convex portion 36 of the gauge main body 3 can engage with the concave portion 56 at a position where the stopper 4 can be positioned. As described above, since the sliding contact convex portion 36 is in contact with the bottom surface 51 while accumulating elastic repulsive force, the sliding contact convex portion 36 has elasticity on the sliding contact surface 57 when the gauge main body 3 is slid. It is biased or resiliently engaged with the recess 56. Thereby, a moderation mechanism capable of easily realizing accurate positioning of the gauge G is realized.

  In the present embodiment, as shown in FIGS. 8 to 13, the upper end 4a of the stopper 4 is located below the sheet placement surface M at the storage position (s) and the upper end 4a of the stopper 4 at the guide position (g). The gauge elevating mechanism X is provided to raise and lower the gauge G by using the slide operation of the gauge G so that the sheet G is positioned above the sheet placement surface M.

  FIG. 8 shows a state where the gauge G is in the storage position (s). In this state, the guide projection 53 is in contact with both the upper rail 32 and the lower rail 33 of the gauge body 3. Particularly in the gauge main body 3, the lower rail 33 is sandwiched between the holding plane 55b formed at the lower end of the lower guide surface 55 and the bottom surface 51, and is positioned at the storage position (s). At the same time, the upper rail 32 is slightly in contact with the curved surface 54 a provided on the upper guide surface 54. When the operation of pulling out the gauge G from the gauge holding portion 5 is started from the state shown in FIG. 8, the lower rail 33 and the guide ridge 53 separate from each other as shown in FIG. , Starts sliding while sliding on the curved surface 54a. Then, in the state shown in FIG. 10, the upper end 4a of the stopper 4 rises completely above the sheet receiving surface 17, ie, the sheet placing surface M, and at the guide position (g) shown in FIG. By placing the rail 32 on a support plane formed at the upper end of the upper guide surface 54, the elevated state of the gauge body 3 is suitably maintained.

  Then, when the gauge main body 3 is slid toward the inward end by pushing the stopper 4 or the like so as to set the gauge G from the guide position (g) to the storage position (s), as shown in FIG. And the upper guide surface 54 are separated, and the lower rail 33 and the lower guide surface 55 come in contact with each other. Then, as the lower rail 33 slides on the curved surface 55a of the lower guide surface 55 as shown in FIG. 13 by the further slide operation, the gauge main body 3 descends, and again the storage position (s) shown in FIG. Become. Thus, the gauge elevating mechanism X raises and lowers the gauge main body 3 by the upper rail 32, the lower rail 33, and the guide projection 53 constituting a slide cam mechanism. In other words, the gauge lifting mechanism X is configured to lift and lower the gauge body 3 by means of a slide cam mechanism provided between the punch body and the gauge body 3.

  With the above configuration, the punch A, which is the sheet processing apparatus according to the present embodiment, raises and lowers the gauge G by using the slide operation of the gauge G, and thus, the slide operation of the gauge G naturally results in use position Reciprocation from the guide position (g) to the storage position (s) is realized. As a result, the user only needs to perform the slide operation when using the gauge G. That is, according to the present invention, the present invention contributes to the provision of the punch A which is easy to perform at least the operation for reliably setting the gauge G at the desired position.

  Further, in the present embodiment, the upper end 4a of the stopper 4 is raised or lowered from above the sheet setting surface M to the sheet setting surface M or less, specifically to the substantially flush upper and lower positions by the gauge lifting mechanism X The interference with the sheet of the gauge G at the storage position (s) is effectively avoided.

  As an effective configuration for stabilizing the sliding movement of the gauge G, in the present embodiment, the receiving bottom U includes a bottom surface 51 for supporting the gauge main body 3 from the lower side and a guiding side surface 52 for guiding the gauge main body 3 from the side. The configuration in which the provided gauge holder 5 is provided is applied.

  Further, in the present embodiment, the gauge main body 3 is gradually increased in thickness from the inward end to the outward end in the present embodiment in order to make the accurate slide operation of the gauge G and the elevation operation by the gauge elevating mechanism X compatible with a simple configuration. Only the lower surface of the inner end portion is in sliding contact with the bottom surface 51 of the gauge holding portion 5 by the sliding contact portion 36 while the tapered surface 34 whose dimension is reduced is provided. Thereby, even with a simple configuration in which only the outer end of the gauge G is moved up and down, reliable operation of the gauge lifting and lowering mechanism X is realized.

  In the present embodiment, the gauge elevating mechanism X raises and lowers the gauge main body 3 by the slide cam mechanism provided between the punch main body 1 and the gauge main body 3. Both positioning and reliable lifting and lowering.

  Further, in the present embodiment, as an effective configuration for realizing the stable operation of the gauge G, the slide cam mechanism includes a lower rail 33 projecting from the side surface of the gauge main body 3 and an inner side of the lower rail 33. An upper rail 32 positioned on the end side and protruding from the side surface of the gauge main body 3 and an inner side surface of the gauge holding portion 5 are protrudingly engaged with an inner end of the lower rail 33 to lower the gauge main body 3 The lower guide surface 55 for guiding in the direction and the guide ridge 53 having the upper guide surface 54 for guiding the gauge main body 3 in the upward direction are engaged with the outer end of the upper rail 32.

  In addition, in order to realize the simplification of the further composition of gauge G, gauge G is integrally formed with gauge body 3 and stopper 4 in this embodiment.

  Further, in the present embodiment, by applying to the punch A having the punching mechanism 2 as the processing mechanism, accurate punching of the punch A into the sheet is realized.

Specifically, as shown in the upper side of the figure, the upper end 4a of the stopper 4 is held by holding the rail of the gauge main body 3 between the holding flats 55b of the guide ridges 53 formed in the upper and lower two at the storage position (s). Is positioned below the sheet placement surface M (not shown). Then, when the engagement between the guide projection 53 and the rail is released by sliding the gauge main body 3, the gauge main body 3 is urged upward by the urging means X1, and the guide position (g) is realized.

  Even in such a case, as in the above embodiment, the provision of the punch A, which is a sheet processing apparatus that facilitates an operation for reliably setting the gauge G at a desired position, is realized.

  As mentioned above, although embodiment of this invention was described, the specific structure of each part is not limited only to embodiment mentioned above, A various deformation | transformation is possible in the range which does not deviate from the meaning of this invention.

  For example, although the above-mentioned embodiment disclosed a mode in which the gauge elevating mechanism urges only the vertical movement of the gauge, it is a matter of course that the state of the stopper is placed by carrying out the rotation and back and forth movement of the gauge by slide operation. It may be positioned above the surface.
