Description

Staple removal device and guide

The present invention relates to a stapler removal device for pulling out staples from a book that has been folded in two and bound, and a guide installed in the stapler removal device.

Previously, a device for removing a stapler from a paper bundle after it has been bound by a stapler is known to have a structure in which a wedge-shaped member is inserted between the paper bundle and the crown of the stapler that binds the paper bundle to pull the stapler out of the paper bundle (see patent documents 1 and 2).

The paper bundle after stapled at the end or corner, etc., is treated as the object of staple removal. The size of the paper bundle inserted into the opening is suppressed to the minimum necessary to prevent the device from becoming large-scale.

[Patent Document 2] Japanese Patent Publication No. 2019-022923

In addition, since the book is folded in two, there is also a form in which the center of the paper pages is stapled. However, in the above-mentioned previous device, the dimension of the paper bundle in the direction of the depth of the opening is suppressed to the necessary minimum, so even if the book is opened after the book is folded in two, the center of the paper pages is stapled, so the staples cannot be set to the staple removal position made by the wedge-shaped member.

When considering the structure of the device for removing the staples from the position of the stapler when the book is opened to the position of the stapler removal made by the wedge-shaped member, the dimension of the depth of the opening into which the book is inserted must be the length of the paper surface of one side of the book in the opened state, and the device is large-scale.

Here, a stapler removal device is provided for removing staples from a book after the book is folded and bound in two, and a guide installed in the stapler removal device is provided.

In order to solve the above-mentioned problem, the stapler removal device of the present application includes: a positioning part, which is bound by a stapler composed of a crown part and a leg part, and contacts the fold of the booklet that is bent along the extension direction of the crown part; a guiding part, which guides the fold of the booklet to the positioning part; and a removal part, which moves in a direction intersecting the fold of the booklet to be locked with the crown part of the stapler binding the booklet, and has a force in the direction of pulling the stapler out of the booklet, acting on the action part of the stapler.

In the staple removing device, the fold of the booklet is guided to the alignment part by the guide part. The removing part is locked with the crown part of the staple of the booklet after the binding fold contacts the alignment part, so that the force in the direction of pulling the staple out of the booklet acts on the staple, thereby removing the staple from the booklet. The guide of this application is installed in the stapler removal device, which includes: a positioning part, which is bound by a stapler composed of a crown part and a leg part, and the fold of the book after being bent along the extension direction of the crown part will be in contact; and a removal part, which moves in a direction intersecting the fold of the book to be locked with the crown part of the stapler binding the book, and has a force in the direction of pulling the stapler out of the book, and acts on the stapler; its feature is that it includes a guide part that guides the fold of the book to the positioning part.

In the stapler removal device, the booklet that is bent due to the fold is not opened, and the guide part can be used to set the booklet to a predetermined position, and the stapler can be pulled out from the booklet. The guide is installed in the stapler removal device, and the booklet that is bent due to the fold is not opened, and the booklet can be set to a predetermined position, and the stapler can be pulled out from the booklet by the stapler removal device.

<Structural example of the stapler removal device in the first embodiment>

FIG. 1A is a side sectional view of an example of the stapler removal device of the first embodiment; FIG. 1B is a side view of an example of the stapler removal device of the first embodiment; and FIG. 1C is a top view of an example of the stapler removal device of the first embodiment. Moreover, FIG. 2A and FIG. 2B are three-dimensional views of an example of the stapler removal device of the first embodiment; and FIG. 3A and FIG. 3B are exploded three-dimensional views of an example of the stapler removal device of the first embodiment. Moreover, FIG. 4A is a side view of a booklet of an example of the stapler removal device of the first embodiment after being set; and FIG. 4B is a three-dimensional view of a booklet of an example of the stapler removal device of the first embodiment after being set. In addition, FIG. 5 is an explanatory diagram showing an example of a stapler after binding the booklet P; FIG. 6 is a three-dimensional diagram showing an example of a booklet bound by a stapler.

First, referring to FIG. 5 and FIG. 6, the stapler 100 after binding the booklet P and the booklet P bound by the stapler 100 are described.

The two ends of the crown 101 of the stapler 100 are bent in one direction to form a pair of legs 102. After the stapler 100 penetrates the booklet P, the pair of legs 102 are bent inwards respectively. In this way, the booklet P is bound by the stapler 100.

The booklet P is bound by the stapler 100 in the center of the paper pages, which is called a center binding. It is a two-fold book binding form after the binding position made by the stapler 100 is bent along the extension direction of the crown part 101. Thereby, the booklet P is formed with a fold P1 along the extension direction of the crown part 101 of the stapler 100. In addition, the booklet P is folded in the direction that the crown part 101 is located on the convex side (peak side) of the fold P1 and the foot part 102 is located on the concave side (valley side).

Next, referring to the figures, the stapler removal device 1A of the first embodiment for removing the stapler 100 from the booklet P is described.

The stapler removal device 1A of the first embodiment, as shown in FIG. 1 , FIG. 4A and FIG. 4B , is a structure in which the booklet P is set in the direction along the vertical direction. The stapler removal device 1A includes: a positioning portion 2A, which the fold P1 of the booklet P will contact; an opening portion 3A, when the fold P1 of the booklet P contacts the positioning portion 2A, the crown portion 101 of the stapler 100 after binding the booklet P will enter; and a guide portion 4A, which guides the positioning portion 2A to the fold P1 of the booklet P.

The alignment portion 2A is formed by a surface having a length in the direction along the fold P1 of the booklet P that contacts the alignment portion 2A, which is longer than the length in the direction along the thickness direction of the booklet P. The alignment portion 2A is longitudinally formed along the direction of the fold P1 of the booklet P, and transversely formed along the thickness direction of the booklet P, and is disposed on both sides of the opening portion 3A along the longitudinal direction. The alignment portion 2A can also be disposed transversely on at least one side of the opening portion 3A. In this example, the alignment portion 2A is formed by the first surface 21A of the frame 20A constituting the exterior of the staple removal device 1A. The staple removal device 1A of the first embodiment is placed with the first surface 21A in a horizontal direction.

The opening portion 3A has a longitudinal dimension along the alignment portion 2A that is longer than the longitudinal length of the crown portion 101 of the stapler 100, and a transverse dimension along the alignment portion 2A that is longer than the transverse length of the crown portion 101. This longer opening is provided in the alignment portion 2A. In this example, as shown in FIG. 3A , the opening portion 3A penetrates the first surface 21A of the frame 20A and is formed by a portion of the opening extending transversely along the alignment portion 2A.

The guide portion 4A includes a first guide portion 41A and a second guide portion 42A that protrude in a direction that intersects the longitudinal and transverse directions of the alignment portion 2A. In other words, the guide portion 4A protrudes in a direction that intersects the alignment portion 2A. The first guide portion 41A and the second guide portion 42A clamp the opening portion 3A in the transverse direction of the alignment portion 2A to face each other.

The guide portion 4A is formed along the interval between the first guide portion 41A and the second guide portion 42A in the lateral direction of the alignment portion 2A, beside the portion where the booklet P contacts the alignment portion 2A, in other words, at the portion where the end of the first guide portion 41A on the alignment portion 2A side protruding from the alignment portion 2A and the end of the second guide portion 42A on the alignment portion 2A side face each other, and is formed to be equal to or greater than the thickness of the booklet P in the form of a two-fold book binding. Furthermore, as the distance from the alignment portion 2A increases, the interval between the first guide portion 41A and the second guide portion 42A in the lateral direction of the alignment portion 2A becomes wider, and the surfaces facing each other between the first guide portion 41A and the second guide portion 42A are inclined surfaces that are inclined relative to the direction perpendicular to the alignment portion 2A, forming a cone shape.

In this example, the guide portion 4A is structured such that the second guide portion 42A is a separate part from the frame 20A and is mounted on the first surface 21A by screws 45A. Furthermore, the mounting position of the second guide portion 42A can also be configured to be selectable, so that the interval between the first guide portion 41A and the second guide portion 42A in the lateral direction of the alignment portion 2A can be changed in accordance with the thickness of the booklet P.

The guide portion 4A includes indicator portions 43A and 44A for aligning the position of the stapler 100 after binding the booklet P to the opening portion 3A. The indicator portion 43A is structured such that a concave portion extending in a direction away from the opening portion 3A is provided on the surface of the first guide portion 41A facing the second guide portion 42A to match the position of the opening portion 3A. The indicator portion 44A is a concave portion extending in a direction away from the opening portion 3A (or the alignment portion 2A) to match the position of the opening portion 3A on the surface of the second guide portion 42A facing the first guide portion 41A. The indicator portions 43A and 44A may also be provided to replace the opening portion 3A so that the position of the stapler 100 matches the action portion described later.

Furthermore, the indicator parts 43A and 44A may be printed and displayed by a plurality of lines defining the range where the opening part 3A is provided, a band matching the opening part 3A, etc. Also, the indicator part may be provided on at least one of the first guide part 41A and the second guide part 42A. Furthermore, the indicator part may not be provided on both the first guide part 41A and the second guide part 42A.

The stapler removal device 1A is such that when the booklet P enters between the first guide portion 41A and the second guide portion 42A, the fold P1 of the booklet P is guided to the alignment portion 2A. After the crown portion 101 of the stapler 100 that has bound the booklet P is aligned with the opening portion 3A, when the fold P1 of the booklet P contacts the alignment portion 2A, the crown portion 101 enters the opening portion 3A.

The staple removal device 1A includes a removal portion 5A for pulling out the staple 100 from the booklet P. The removal portion 5A includes a wedge plate assembly 50A and a driving portion 51A for driving the wedge plate assembly 50A. The wedge plate assembly 50A includes a wedge plate 500A and a supporting portion 501A on which the wedge plate 500A is mounted.

The wedge plate 500A is an example of an action part, and the dimension along the longitudinal direction of the alignment part 2A is shorter than the crown part 101 of the stapler 100. In addition, the dimension of the wedge plate 500A along the direction perpendicular to the first surface 21A of the frame 20A in the longitudinal and transverse directions of the cross alignment part 2A is narrowed on the tip side to the extent that the crown part 101 of the stapler 100 enters the binding booklet P and the booklet P. Moreover, the wedge plate 500A is formed in a shape that is inclined in the direction in which the dimension along the direction perpendicular to the first surface 21A of the frame 20A becomes longer from the tip to the part installed on the support part 501A.

The support portion 501A is provided with a shaft 503A on the side where the wedge plate 500A is installed, and a shaft 502A is provided on the opposite side of the side where the wedge plate 500A is installed. The shaft 502A and the shaft 503A protrude from both sides of the support portion 501A along the longitudinal direction of the alignment portion 2A.

The wedge assembly 50A is composed of shafts 502A and 503A, which enter into a long hole 22A formed in a pair of unillustrated frames provided in the frame 20A.

The driving part 51A includes: a gear 510A, which is disposed on the supporting part 501A; a gear 511A, which meshes with the gear 510A; and a gear group (not shown) which transmits the driving force of the motor 512A to the gear 511A.

When the operation button 8A of the staple removal device 1A is pressed, the motor 512A rotates forward and reverse according to the position of the wedge assembly 3D 50A detected by the unillustrated detector. The removal part 5A is rotated by the motor 512A, and the driving force is transmitted to the wedge assembly 3D 50A through the gear 511A and the gear 510A.

The wedge plate assembly 50A moves along the long hole 22A extending in the horizontal direction of the alignment part 2A with the shaft 502A and the shaft 503A, thereby the wedge plate 500A moves in the horizontal direction of the alignment part 2A. When the booklet P is set in the guide part 4A and the fold P1 of the booklet P contacts the alignment part 2A, the wedge plate 500A moves in a direction intersecting with the fold P1 of the booklet P. In addition, the wedge plate assembly 50A rotates with the shaft 503A as a fulcrum when the shaft 503A is guided by the long hole 22A, and the wedge plate 500A enters and exits relative to the opening part 3A. That is, the wedge plate 500A enters the opening part 3A. In other words, when the fold P1 of the booklet P contacts the alignment portion 2A, the wedge plate 500A enters the opening portion 3A into which the crown portion 101 of the stapler 100 enters after binding the booklet P.

The removal portion 5A is located at the lower side of the second guide portion 42A, on the inner surface side of the first surface 21A, and can move back and forth between a standby position where the wedge plate 500A retreats from the opening portion 3A and an actuating position where the wedge plate 500A passes through the opening portion 3A and is located at the lower side of the first guide portion 41A.

Thus, the removal part 5A exerts the function of the wedge plate 500A moving in the direction from the standby position to the crown part 101 approaching the entry opening part 3A, in the direction intersecting the fold P1 of the booklet P, and by entering between the crown part 101 and the booklet P, being locked with the crown part 101, exerting the force in the direction of pulling the staple 100 out of the booklet P, and acting on the action part of the staple 100.

Furthermore, the guide portion 4A is provided at the downstream side of the opening portion 3A (or the positioning portion 2A) with respect to the moving direction of the wedge plate 500A from the standby position to the crown portion 101 approaching the opening portion 3A. Furthermore, the guide portion 4A is provided at the upstream side of the opening portion 3A (or the positioning portion 2A) with respect to the moving direction of the wedge plate 500A from the standby position to the crown portion 101 approaching the opening portion 3A.

The stapler removal device 1A includes a needle stopper 6A that limits the movement of the crown portion 101 by the action of the wedge plate 500A entering between the crown portion 101 and the booklet P. The needle stopper 6A is arranged on the downstream side of the opening portion 3A relative to the movement direction of the wedge plate 500A from the standby position to the crown portion 101 approaching and entering the opening portion 3A. The needle stopper 6A is configured to be movable in the direction of approaching and moving away from the inner surface of the first surface 21A by rotating with the shaft 60A as a fulcrum, and is pushed in the direction of contacting the inner surface of the first surface 21A by a spring not shown in the figure.

The stapler removal device 1A includes a waste stapler insertion hole 7A into which the stapler 100 removed from the booklet P enters. The waste stapler insertion hole 7A is provided at the lower side of the opening portion 3A, and by the action of the removal portion 5A, the stapler 100 removed from the booklet P falls down by its own weight. The structure of the waste stapler insertion hole 7A is such that the stapler 100 can be inserted and removed relative to the frame 20A, and the stapler 100 can be ejected.

<Operation example of the stapler removal device in the first implementation form>

Figures 7A to 7D are side sectional views showing an example of the operation of the stapler removal device of the first embodiment; Figures 8A to 8B are side sectional views of important parts showing an example of the operation of the stapler removal device of the first embodiment.

As shown in FIG. 4A and FIG. 4B , the stapler removal device 1A makes the fold P1 after being bound by the stapler 100 face downward, and in the closed state, the booklet P enters between the first guide part 41A and the second guide part 42A constituting the guide part 4A.

The guide portion 4A is formed along the interval between the first guide portion 41A and the second guide portion 42A in the horizontal direction of the alignment portion 2A, and gradually narrows to form a cone shape from the side farther from the alignment portion 2A to the side of the portion in contact with the alignment portion 2A. Therefore, when the booklet P enters between the first guide portion 41A and the second guide portion 42A, the fold P1 is guided to the alignment portion 2A.

Furthermore, the crown portion 101 of the stapler 100 after binding the booklet P is aligned with the indicator portion 43A or the indicator portion 44A, or the indicator portion 43A and the indicator portion 44A, so that the booklet P enters between the first guide portion 41A and the second guide portion 42A.

Thus, as shown in FIG. 7A , when the booklet P enters between the first guide portion 41A and the second guide portion 42A, the fold P1 of the booklet P is in the longitudinal direction of the alignment portion 2A, and the fold P1 of the booklet P is guided to a position that contacts the alignment portion 2A.

Furthermore, the crown 101 of the stapler 100 after binding the booklet P is aligned with the indicator parts 43A and 44A, whereby the crown 101 is aligned with the opening part 3A. When the crown 101 is aligned with the opening part 3A, when the fold P1 of the booklet P contacts the alignment part 2A, the crown 101 enters the opening part 3A.

The stapler removal device 1A is provided with an opening 3A between the first guide 41A and the second guide 42A. Therefore, when the booklet P enters between the first guide 41A and the second guide 42A, it becomes difficult to visually identify the position of the opening 3A. In contrast, by including the indicator parts 43A and 44A in the guide 4A, the crown 101 of the stapler 100 can be aligned to the position of the opening 3A.

In this way, the stapler removal device 1A includes a guide portion 4A and indicator portions 43A and 44A on the guide portion 4A, making it easy to set the booklet P to a predetermined position where the stapler 100 can be removed.

When the operation button 8A of the staple removal device 1A is pressed, the motor 512A rotates forward, thereby, as shown in FIG. 7B and FIG. 8A, the wedge plate assembly 50A moves in a direction intersecting with the fold P1 of the booklet P, and as shown by arrow F, the wedge plate 500A moves from the standby position to the direction approaching the crown portion 101 entering the opening portion 3A. In addition, the wedge plate assembly 50A is guided by the shaft 503A to the long hole 22A, thereby rotating with the shaft 503A as a fulcrum, and the wedge plate 500A enters the opening portion 3A. Moreover, the wedge plate 500A contacts the crown portion 101 of the staple 100.

The stapler removal device 1A is in a state where the wedge plate 500A contacts the crown portion 101 of the stapler 100. When the wedge plate 500A moves further in the direction of arrow F, the booklet P is pushed in the direction of the first guide portion 41A.

The guide portion 4A is the interval between the first guide portion 41A and the second guide portion 42A along the lateral direction of the alignment portion 2A. The portion next to the portion in contact with the alignment portion 2A is the same thickness as the booklet P, so the movement of the booklet P and the stapler 100 after binding the booklet P is restricted.

Furthermore, when the crown 101 of the stapler 100 contacts the needle stopper 6A, the movement of the stapler 100 is also restricted. As a result, as shown in FIG. 7C and FIG. 8B , the wedge plate 500A enters between the crown 101 of the stapler 100 and the booklet P.

As shown in FIG. 7D , the stapler removal device 1A is in a state where the wedge plate 500A enters between the crown portion 101 of the stapler 100 and the booklet P. When the wedge plate 500A moves further in the direction of arrow F, the force in the direction of pulling the stapler 100 out of the booklet P acts on the stapler 100, and the foot 102 is lifted while being pulled out of the booklet P. After the foot 102 is pulled out of the booklet P, the stapler 100 falls to the waste stapler insertion hole 7A by its own weight and is received.

The staple removal device 1A detects the position of the wedge assembly 50A with a detector not shown in the figure. When the wedge 500A moves from the booklet P to the actuation position for pulling out the staple 100, the motor 512A is reversed. Thus, the wedge assembly 50A moves in a direction intersecting with the fold P1 of the booklet P, and the wedge 500A moves from the actuation position to the standby position.

Thus, the stapler removal device 1A can be set in a closed state without opening the booklet P which is bound by folding the book in two, and remove the stapler 100. In the state after the booklet P is opened, the distance between the stapler 100 and the end of the booklet P becomes longer. When considering the structure of the stapler removal device for removing the stapler 100 from the position of the opening portion 3A in the state after the booklet P is opened, a space is required to carry the booklet P in the opened state, and the device is large-scaled.

In contrast, the stapler removal device 1A includes a guide portion 4A, which is set to cross the direction of the booklet P in the closed state for the alignment portion 2A having the opening portion 3A into which the crown portion 101 enters, thereby preventing the device from becoming larger.

Furthermore, the second guide portion 42A can be removed from the first surface 21A, and the first surface 21A can be used as a paper bundle placement seat, so that the stapler removal device 1A can also be used as a device for removing staples from a paper bundle in a state where the ends of the paper sheets are stapled. In this case, the first guide portion 41A can also be replaced with a structure that presses the paper bundle toward the paper surface to restrict the movement of the paper bundle.

The alignment part 2B is similar to the alignment part 2A, and is composed of a surface whose length along the direction of the fold P1 of the booklet P that contacts the alignment part 2B is longer than the length along the thickness direction of the booklet P, and is provided on both sides of the opening part 3B along the longitudinal direction. In this example, the alignment part 2B is composed of the first surface 21B of the frame 20B that constitutes the exterior of the staple removal device 1B. The staple removal device 1B of the second embodiment is placed with the first surface 21B in a vertical direction.

The opening portion 3B has a longitudinal dimension along the alignment portion 2B that is longer than the longitudinal length of the crown portion 101 of the stapler 100 shown in FIG. 5, etc., and a transverse dimension along the alignment portion 2B that is longer than the transverse length of the crown portion 101, and is provided in the alignment portion 2B.

The guide portion 4B includes a first guide portion 41B and a second guide portion 42B that protrude in a direction that approximately intersects the longitudinal and transverse directions of the alignment portion 2B. The first guide portion 41B and the second guide portion 42B clamp the opening portion 3B in the transverse direction of the alignment portion 2B to face each other.

The guide portion 4B is the interval between the first guide portion 41B and the second guide portion 42B along the lateral direction of the alignment portion 2B, and is equal to the thickness of the booklet P beside the portion in contact with the alignment portion 2B. In addition, the guide portion 4B is the first guide portion 41B extending in the horizontal direction, and the interval between the first guide portion 41B and the second guide portion 42B along the lateral direction of the alignment portion 2B becomes wider as it is farther away from the alignment portion 2B. The surface of the second guide portion 42B facing the first guide portion 41B is an inclined surface inclined relative to the direction perpendicular to the alignment portion 2B, and forms a cone shape.

The guide portion 4B includes indicators 43B and 44B that align the position of the staple 100 after binding the booklet P with the opening portion 3B. The indicator 43B is a concave portion extending in a direction away from the opening portion 3B, which is set on the surface of the first guide portion 41B facing the second guide portion 42B and is aligned with the position of the opening portion 3B. The indicator 44B is a concave portion extending in a direction away from the opening portion 3B, which is set on the surface of the second guide portion 42B facing the first guide portion 41B and is aligned with the position of the opening portion 3B. A concave portion may be formed on a certain surface to form a concave-convex shape, or a convex portion may be formed on a certain surface to form a concave-convex shape.

Furthermore, the indicator parts 43B and 44B may be printed and displayed by a plurality of lines defining the range where the opening part 3B is provided, a belt matching the opening part 3B, etc. The structure of the indicator parts 43B and 44B may also be composed of a concave-convex shape or a display, or a combination of the two. Furthermore, the indicator part may be provided on at least one of the first guide part 41B and the second guide part 42B. Furthermore, the indicator part may not be provided on both the first guide part 41B and the second guide part 42B.

The staple removal device 1B includes a removal portion 5B for removing the staple 100 from the booklet P. The removal portion 5B only needs to have the same structure as the removal portion 5A, and includes a wedge plate assembly 50B and a driving portion 51B for driving the wedge plate assembly 50B. The wedge plate assembly 50B includes a wedge plate 500B and a supporting portion 501B on which the wedge plate 500B is mounted.

The wedge plate 500B is an example of an action part, and its longitudinal dimension along the alignment part 2B is shorter than the crown part 101 of the stapler 100. In addition, the dimension of the wedge plate 500B along the direction perpendicular to the first surface 21B of the frame 20B in the longitudinal and transverse directions of the cross alignment part 2B is narrowed on the tip side to the extent that the crown part 101 of the stapler 100 enters the binding booklet P and the booklet P. Moreover, the wedge plate 500B is formed by the dimension along the direction perpendicular to the first surface 21B of the frame 20B, and is inclined in a longer direction from the tip to the part installed on the support part 501B.

The support portion 501B is provided with a shaft 503B on the side where the wedge plate 500B is installed, and a shaft 502B is provided on the opposite side of the side where the wedge plate 500B is installed. The shaft 502B and the shaft 503B protrude from both sides of the support portion 501B along the longitudinal direction of the alignment portion 2B.

The wedge assembly 50B is composed of shafts 502B and 503B, which enter into a long hole 22B formed in a pair of frames 23B provided in the frame 20B.

The driving part 51B includes: a gear 510B, which is disposed on the supporting part 501B; a gear 511B, which meshes with the gear 510B; and a gear group (not shown) which transmits the driving force of the motor 512B to the gear 511B.

When the operation button 8B of the staple removal device 1B is pressed, the motor 512B rotates forward and reverse according to the position of the wedge assembly 50B detected by the unillustrated detector. The removal part 5B rotates by the motor 512B, and the driving force is transmitted to the wedge assembly 50B through the gear 511B and the gear 510B.

The wedge assembly 50B is a shaft 502B and a shaft 503B, and moves along the long hole 22B extending in the horizontal direction of the alignment part 2B, thereby the wedge 500B moves in the horizontal direction of the alignment part 2B. When the booklet P is set on the guide part 4B and the fold P1 of the booklet P contacts the alignment part 2B, the wedge 500B moves in a direction intersecting with the fold P1 of the booklet P.

The structure of the removal part 5B is such that it can move back and forth between a standby position where the wedge plate 500B is located behind the second guide part 42B and retreats from the opening part 3B, and an operating position where the wedge plate 500B passes through the opening part 3B and is located behind the first guide part 41B.

The stapler removal device 1B includes a waste stapler insertion hole 7B into which the stapler 100 removed from the booklet P enters. The waste stapler insertion hole 7B is disposed at the lower inner side of the opening portion 3B, and the stapler 100 removed from the booklet P falls down by its own weight due to the action of the removal portion 5B. The waste stapler insertion hole 7B is structured so that it can be inserted and removed relative to the frame 20B, and the stapler 100 can be ejected.

As shown in FIG. 10B , the stapler removal device 1B is a first guide portion 41B constituting the guide portion 4B, and the fold P1 after being bound by the stapler 100 is regarded as a horizontal direction. In a closed state, a booklet P is placed, and the booklet P enters between the first guide portion 41B and the second guide portion 42B.

The guide portion 4B is formed into a cone shape that gradually narrows from the side away from the alignment portion 2B to the side of the portion in contact with the alignment portion 2B along the interval between the first guide portion 41B and the second guide portion 42B in the lateral direction of the alignment portion 2B. Therefore, by placing the booklet P on the first guide portion 41B and entering between the first guide portion 41B and the second guide portion 42B, the fold P1 is guided to the alignment portion 2B.

Furthermore, the crown portion 101 of the stapler 100 after binding the booklet P is aligned with the indicator portion 43B or the indicator portion 44B, or the indicator portion 43B and the indicator portion 44B, so that the booklet P enters between the first guide portion 41B and the second guide portion 42B.

Thus, when the booklet P enters between the first guide portion 41B and the second guide portion 42B, the fold P1 of the booklet P is oriented along the longitudinal direction of the alignment portion 2B, and the fold P1 of the booklet P is guided to a position where it contacts the alignment portion 2B.

Furthermore, the crown 101 of the stapler 100 after binding the booklet P is aligned with the indicator parts 43B and 44B, whereby the crown 101 is aligned with the opening part 3B. When the crown 101 is aligned with the opening part 3B, when the fold P1 of the booklet P contacts the alignment part 2B, the crown 101 enters the opening part 3B.

In this way, the stapler removal device 1B includes a guide portion 4B, and the guide portion 4B includes indicator portions 43B and 44B, so that the booklet P can be easily set to a predetermined position where the stapler 100 can be removed.

Moreover, in the stapler removal device 1B, the action of removing the stapler 100 from the booklet P by the removal part 5B is the same as that of the stapler removal device 1A, and the wedge plate 500B moves back and forth in a direction perpendicular to the booklet P, enters between the crown part 101 of the stapler 100 and the booklet P, and removes the stapler 100 from the booklet P. After being removed from the booklet P, the stapler 100 falls to the waste stapler insertion hole 7B by its own weight.

<Other implementation examples of stapler removal device>

The staple removal device of the present invention is not limited to the above-mentioned implementation forms, but also includes the following implementation forms.

FIG. 11A and FIG. 11B are three-dimensional diagrams showing an example of a staple removal device in another embodiment.

The stapler removal device 1C of other embodiments is a variation of the removal portion of the stapler removal device 1A of the first embodiment. Therefore, in the stapler removal device 1C, the alignment portion 2A (not shown in FIG. 11A ) contacted by the fold P1 of the booklet P, the opening portion 3A (not shown in FIG. 11A and FIG. 11B ) into which the crown portion 101 of the stapler 100 after binding the booklet P enters when the fold P1 of the booklet P contacts the alignment portion 2A, and the guide portion 4A that guides the fold P1 of the booklet P to the alignment portion 2A, are all that is required to be the same structure as the stapler removal device 1A of the first embodiment.

The staple removal device 1C includes a removal portion 5C for pulling out the staple 100 from the booklet P. The removal portion 5C includes a wedge assembly 50C and a driving portion 51C for driving the wedge assembly 50C. The wedge assembly 50C includes a wedge 500C and a supporting portion 501C on which the wedge 500C is mounted.

The support part 501C is supported rotatably on a frame (not shown) provided on the frame body 20A, with the shaft 520C as a fulcrum at one end thereof. In addition, the support part 501C is provided with a wedge part 500C at the other end thereof which is displaced in a circle by the rotation action with the shaft 520C as a fulcrum.

The wedge portion 500C is an example of an action portion, and is composed of an arc shape of a track of the other end side of the support portion 501C that describes a circular displacement along the rotation of the support portion 501C with the shaft 520C as a fulcrum. The wedge portion 500C is mounted on the support portion 501C at the rear end side of one end along the circumferential direction of the arc shape.

The wedge portion 500C is shorter than the crown portion 101 of the stapler 100 along the longitudinal dimension of the alignment portion 2A. In addition, the wedge portion 500C is narrowed along the radial dimension of the arc shape to the extent between the crown portion 101 of the stapler 100 and the booklet P after entering the booklet P for binding at the tip side of the other end along the circumferential direction of the arc shape. Moreover, the wedge portion 500C is formed by a shape that is inclined in a curved shape in a direction that becomes longer from the tip to the rear end side of the support portion 501C installed along the radial dimension of the arc shape. Moreover, the wedge portion 500C may also be a shape that becomes wider from the tip side to the rear end side along the longitudinal dimension of the alignment portion 2A.

The driving part 51C includes: a gear 510C, which is disposed on a shaft 520C of the supporting part 501C; and a gear group 511C, which transmits the driving force of the motor 512C to the gear 510C.

When the operation button 8A of the staple removal device 1C is pressed, the motor 512C rotates forward and reverse according to the position of the wedge assembly 50C detected by the unillustrated detector. The removal part 5C is rotated by the motor 512C, and the driving force is transmitted to the wedge assembly 50C through the gear group 511C and the gear 510C.

The wedge assembly 50C is a support part 501C that rotates with the shaft 520C as a fulcrum, whereby the wedge 500C is displaced in a circular arc by the rotation action with the shaft 520 as a fulcrum. Thereby, the arc-shaped wedge 500C is displaced in the circumferential direction, and the wedge 500C is moved in the lateral direction of the positioning part 2A. Moreover, the displacement of the wedge 500C by the rotation action with the shaft 520C as a fulcrum is called rotation. When the booklet P is set on the guide part 4A and the fold P1 of the booklet P contacts the positioning part 2A, the wedge 500C moves in a direction intersecting with the fold P1 of the booklet P. In addition, the tip and the arc-shaped outer peripheral surface of the wedge portion 500C are formed by the rotation with the shaft 520C as a fulcrum, and the tip and the arc-shaped outer peripheral surface of the wedge portion 500C protrude from the opening portion (not shown) toward the first surface 21A. The tip and the arc-shaped outer peripheral surface of the wedge portion 500C enter and exit relative to the opening portion.

The structure of the removal part 5C is that the wedge part 500C is located below the second guide part 42A and between the standby position on the inner surface side of the first surface 21A and the actuating position below the first guide part 41A through the alignment part 2A, and can be moved back and forth by rotating with the shaft 520C as a fulcrum.

Thus, the removal portion 5C is the wedge portion 500C that rotates using the shaft 520C as a fulcrum, and functions as an action portion in the same manner as the wedge plate 500A.

Figures 12A to 12D are side sectional views showing an example of the operation of the stapler removal device in other embodiments; Figures 13A to 13C are three-dimensional views showing an example of the operation of the stapler removal device in other embodiments.

The stapler removal device 1C is a closed booklet P, as shown in FIG. 5 and FIG. 6 , so that the fold P1 after being bound by the stapler 100 faces downward and enters between the first guide part 41A and the second guide part 42A constituting the guide part 4A. Moreover, the function and effect of the guide part 4A are the same as those of the stapler removal device 1A of the first embodiment described above.

The staple removal device 1C makes the fold P1 of the booklet P be along the longitudinal direction of the alignment part 2A when the booklet P enters between the first guide part 41A and the second guide part 42A, and the fold P1 of the booklet P is guided to the position where it contacts the alignment part 2A.

Furthermore, when the crown portion 101 is aligned with the opening portion (not shown), when the fold P1 of the booklet P contacts the alignment portion 2A, the crown portion 101 enters the opening portion.

Thus, the stapler removal device 1C includes a guide portion 4A, thereby making it easier to set the booklet P to a predetermined position where the stapler 100 can be removed. Furthermore, the stapler removal device 1C includes indicator portions 43A and 44A in the guide portion 4A, thereby making it even easier to set the booklet P to a predetermined position where the stapler 100 can be removed.

When the operation button 8A of the staple removal device 1C is pressed, the motor 512C rotates forward, thereby, as shown in FIG. 12A and FIG. 13A, the wedge assembly 50C moves in a direction intersecting the fold P1 of the booklet P by rotating the wedge 500C with the shaft 520C as a fulcrum. As a result, the wedge 500C moves toward the tip from the standby position toward the direction close to the crown 101 of the staple 100 after the booklet P is bound. Moreover, the tip of the wedge 500C contacts the crown 101.

The stapler removal device 1C is in a state where the wedge portion 500C contacts the crown portion 101 of the stapler 100. When the wedge portion 500C further rotates in the direction of moving from the standby position to the actuating position, as shown in FIG. 12B and FIG. 13B, the wedge portion 500C enters between the crown portion 101 of the stapler 100 and the booklet P.

As shown in FIG. 12C and FIG. 13C, the stapler removal device 1C is in a state where the wedge portion 500C enters between the crown portion 101 of the stapler 100 and the booklet P. When the wedge portion 500C rotates further, the force in the direction of pulling the stapler 100 out of the booklet P acts on the stapler 100, and the foot portion 102 is lifted while being pulled out of the booklet P. After the foot portion 102 is pulled out of the booklet P, the stapler 100 falls to the waste stapler insertion hole 7A by its own weight and is received.

The stapler removal device 1C detects the position of the wedge assembly 50C with a detector not shown in the figure. When the wedge 500C moves to the actuation position for pulling out the staple 100 from the booklet P, the motor 512C is reversed. Thus, as shown in FIG. 12D , the wedge 500C moves from the actuation position to the standby position.

Thus, the stapler removal device 1C can be set in a closed state to remove the stapler, similarly to the stapler removal device 1A, without opening the booklet P which is folded in two and bound. 100.

FIG. 14A and FIG. 14B are three-dimensional diagrams showing another example of a staple removal device in another embodiment.

Another example of the stapler removal device 1D of other embodiments is a modified example of the removal portion of the stapler removal device 1B of the second embodiment, which is a structure in which the booklet P is set in the horizontal direction. Therefore, in the stapler removal device 1D, the alignment portion 2B (not shown in FIG. 14B) contacted by the fold P1 of the booklet P, the opening portion 3B (not shown in FIG. 14A and FIG. 14B) into which the crown portion 101 of the stapler 100 after binding the booklet P enters when the fold P1 of the booklet P contacts the alignment portion 2B, and the guide portion 4B that guides the fold P1 of the booklet P to the alignment portion 2B, can be the same structure as the stapler removal device 1B of the second embodiment.

The staple removal device 1D includes a removal portion 5C for removing the staple 100 from the booklet P. The removal portion 5C includes a wedge assembly 50C and a driving portion 51C for driving the wedge assembly 50C as described in FIG. 11A and FIG. 11B. The wedge assembly 50C includes a wedge 500C and a supporting portion 501C on which the wedge 500C is mounted. The structure of the removal portion 5C is that the wedge 500C rotates with the shaft 520C supported by the frame 22C as a fulcrum.

In the stapler removal device 1D, the booklet P in the form of a book folded in two is not opened, and the action of guiding it to the alignment part 2B in the closed form by the first guide part 41B and the second guide part 42B is the same as that of the stapler removal device 1B.

That is, when the booklet P enters between the first guide portion 41B and the second guide portion 42B, the stapler removal device 1D makes the fold P1 of the booklet P be in the longitudinal direction of the alignment portion 2B, and the fold P1 of the booklet P is guided to a position that contacts the alignment portion 2B. Thus, the stapler removal device 1D also includes the guide portion 4B, thereby making it easy to set the booklet P to a predetermined position where the stapler 100 can be removed.

Furthermore, the guide portion 4B includes indicator portions 43B and 44B, thereby making it easier to set the booklet P to a predetermined position where the stapler 100 can be removed.

Moreover, in the stapler removal device 1D, the action of removing the stapler 100 from the booklet P by the removal part 5C is the same as that of the stapler removal device 1C, and the wedge part 500C enters between the crown part 101 of the stapler 100 and the booklet P by rotating with the shaft 520C as a fulcrum, and removes the stapler 100 from the booklet P. After being removed from the booklet P, the stapler 100 falls to the waste stapler insertion hole 7B by its own weight.

Figures 15A, 15B and 15C are three-dimensional diagrams showing another example of a staple removal device in another embodiment.

Another example of a stapler removal device 1E of another embodiment is a modified example of the removal part of the stapler removal device 1A described above, and is a structure of the removal part being manually operated. Therefore, in the stapler removal device 1E, the alignment part 2A that the fold P1 of the booklet P contacts, the opening part 3A (not shown in FIG. 15A to FIG. 15C ) that the crown part 101 of the stapler 100 after binding the booklet P enters when the fold P1 of the booklet P contacts the alignment part 2A, and the guide part 4A that guides the fold P1 of the booklet P to the alignment part 2A, can be the same structure as the stapler removal device 1A of the first embodiment. The best example is to explain the same structure as the stapler removal device 1A of the first embodiment, which is an example in which the removal part is manual, but it can also be the same structure as the stapler removal device 1A of the second embodiment, which is an example in which the removal part is manual.

The staple removal device 1E includes a removal unit 5E for pulling out the staple 100 from the booklet P. The removal unit 5E includes a wedge assembly 50A and a driving unit 51E for driving the wedge assembly 50A. As described above, the wedge assembly 50A includes a wedge 500A and a support unit 501A on which the wedge 500A is mounted. The removal unit 5E is a linear motion of the wedge 500A guided by the shaft 502A and the shaft 503A, and a rotation using the shaft 503A as an axis, and can move back and forth between the standby position and the actuation position.

The driving part 51E includes a connecting rod 521E that rotates with the shaft 520E as a fulcrum, and a lever 522E that rotates the connecting rod 521E. The connecting rod 521E is supported by the shaft 520E at one end and rotates in conjunction with the shaft 520E. In addition, the connecting rod 521E is connected to the shaft 503A of the supporting part 501A at the other end. The lever 522E is supported by the shaft 520E at one end and rotates in conjunction with the shaft 520E. In addition, the lever 522E includes a hand-operated handle 523E at the other end.

The staple removal device 1E is linked to the shaft 520E when the handle 523E is operated by hand and the lever 522E rotates with the shaft 520E as a fulcrum, and the connecting rod 521E rotates with the shaft 520E as a fulcrum. The removal part 5E rotates by the connecting rod 521E, and the driving force is transmitted to the wedge assembly 50A.

When the handle 523E of the stapler removal device 1E is operated by hand and the lever 522E rotates with the shaft 520E as a fulcrum, the wedge plate 500A moves from the standby position toward the crown 101 of the stapler 100 after the booklet P is bound, and enters between the crown 101 and the booklet P.

After the wedge plate 500A enters between the crown portion 101 of the stapler 100 and the booklet P, when the wedge plate 500A moves further in the direction of moving from the standby position to the actuating position, the force in the direction of pulling the stapler 100 out of the booklet P acts on the stapler 100. As shown in FIG. 15C, the foot portion 102 is lifted while being pulled out of the booklet P. After the booklet P is removed, the stapler 100 falls to the waste staple insertion hole 7A by its own weight.

The staple removal device 1E is that after the wedge plate 500A moves from the stapler P to the actuation position for pulling out the staple 100, when the handle 523E is operated by hand and the lever 522E rotates in the opposite direction using the shaft 520E as a fulcrum, the wedge plate 500A moves from the actuation position to the standby position.

Thus, the stapler removal device 1E is configured to manually actuate the wedge plate 500A of the removal part 5E, so that the booklet P in the form of a book folded in two and bound can be set in a closed state to remove the stapler 100 without opening it.

Figures 16A, 16B and 16C are three-dimensional diagrams showing another example of a stapler removal device in another embodiment.

Another example of the stapler removal device 1F of another embodiment is another variation of the removal part of the stapler removal device 1C which is a variation of the stapler removal device 1A, and is a structure of the removal part being manually operated. Therefore, in the stapler removal device 1F, the alignment part 2A that the fold P1 of the booklet P contacts, the opening part 3A (not shown in FIG. 16A to FIG. 16C ) into which the crown part 101 of the stapler 100 after binding the booklet P enters when the fold P1 of the booklet P contacts the alignment part 2A, and the guide part 4A that guides the fold P1 of the booklet P to the alignment part 2A, may be the same structure as the stapler removal device 1A of the first embodiment. The best example is to explain the same structure as the stapler removal device 1A of the first embodiment, which is an example in which the removal part is manual, but it is also possible to have the same structure as the stapler removal device 1A of the second embodiment and make the removal part manual.

The staple removal device 1F includes a removal portion 5F for pulling out the staple 100 from the booklet P. The removal portion 5F includes a wedge assembly 50C and a driving portion 51F for driving the wedge assembly 50C. As described above, the wedge assembly 50C includes a wedge 500C and a supporting portion 501C on which the wedge 500C is mounted. The structure of the removal portion 5F is that the wedge 500C can move back and forth between a standby position and an actuating position by rotating the shaft 520C as a fulcrum.

The driving part 51F includes a lever 522F of a rotating shaft 520C. The end of the lever 522F is supported by the shaft 520C and rotates in conjunction with the shaft 520C. In addition, the lever 522F includes a hand-operated handle 523F at the end of the other side.

When the handle 523F of the stapler removal device 1F is operated by hand, the lever 522F rotates with the shaft 520C as a fulcrum, and the support portion 501C rotates with the shaft 520C as a fulcrum, thereby the wedge portion 500C rotates from the standby position to the direction close to the crown portion 101 of the stapler 100 after binding the booklet P, and enters between the crown portion 101 and the booklet P.

When the wedge 500C enters between the crown 101 of the stapler 100 and the booklet P, and the wedge 500C rotates in the direction of moving from the standby position to the actuating position, the force in the direction of pulling the stapler 100 out of the booklet P acts on the stapler 100. As shown in FIG. 16C , the foot 102 is lifted and pulled out of the booklet P. After the booklet P is removed, the stapler 100 falls to the waste staple insertion hole 7A by its own weight.

The stapler removal device 1F rotates the wedge portion 500C to the actuation position for pulling out the stapler 100 from the booklet P. When the handle portion 523F is operated by hand, the lever 522F rotates in the opposite direction using the shaft 520C as a fulcrum, and the wedge portion 500C rotates from the actuation position to the standby position.

Thus, the stapler removal device 1F is constructed by manually actuating the removal part 5F, and the booklet P in the form of being folded in two and bound can be set in a closed state to remove the stapler 100 without opening it.

Figures 17A to 17D and Figures 18A to 18D are three-dimensional diagrams showing another example of a stapler removal device in another embodiment.

Another example of a stapler removal device of another embodiment is another variation of the removal portion of the stapler removal device 1C which is a variation of the stapler removal device 1A. The stapler removal device 1G shown in FIG. 17A to FIG. 17D is a device that can simultaneously remove staples 100 at multiple locations along the fold P1 of a book P that is folded in two and bound by staples 100. Furthermore, the stapler removal device 1H shown in FIG. 18A to FIG. 18D is a device that can simultaneously remove the staplers 100 at multiple locations along the fold P1 of a booklet P that is folded in two and bound by staplers 100, and can correspond to the configuration of staplers 100 at different intervals.

The stapler removal device 1G includes, for example, two openings along the fold P1, corresponding to the booklet P bound by the stapler 100, into which the crown 101 of the stapler 100 after binding the booklet P enters when the fold P1 of the booklet P contacts the alignment portion 2A. The opening may be a structure having an opening at multiple locations after being aligned with the binding position of the stapler 100, or a structure having an opening of a length that the stapler 100 enters at multiple locations along the fold P1 of the booklet P.

In addition, the guide portion 4A that guides the fold P1 of the booklet P to the alignment portion 2A is provided with an indicator portion 43A at a plurality of locations of the binding position of the stapler 100 on the surface of the first guide portion 41A facing the second guide portion 42A. In addition, the guide portion 4A is provided with an indicator portion 44A at a plurality of locations of the binding position of the stapler 100 on the surface of the second guide portion 42A facing the first guide portion 41A.

The removal part 5G for pulling out the staple 100 from the booklet P includes: a plurality of wedge assembly bodies 50C, which are arranged to match the binding position of the staple 100; and a driving part 51G, which links each wedge assembly body 50C to drive it. The wedge assembly body 50C includes a wedge part 500C and a supporting part 501C on which the wedge part 500C is installed.

The removal part 5G is mounted on a shaft 520G with a plurality of supporting parts 501C to match the interval of the binding position of the stapler 100. In addition, the driving part 51G includes a lever 522G that rotatably mounts the shaft 520G with a plurality of supporting parts 501C. The end of the lever 522G is supported by the shaft 520G and rotates in conjunction with the shaft 520G. In addition, the lever 522G includes a hand-operated grip part 523G at the end of the other side.

The stapler removal device 1G allows the booklet P in a closed state, with the fold P1 after being bound by the stapler 100 facing downward, to enter between the first guide part 41A and the second guide part 42A constituting the guide part 4A.

The staple removal device 1G makes the fold P1 of the booklet P be along the longitudinal direction of the alignment part 2A when the booklet P enters between the first guide part 41A and the second guide part 42A, and the fold P1 of the booklet P is guided to the position where it contacts the alignment part 2A.

Furthermore, at multiple locations along the fold P1 of the booklet P, in this example, at two locations along the fold P1, when the crowns 101 of the stapler 100 bound with the booklet P are aligned with the opening (not shown), when the fold P1 of the booklet P contacts the alignment portion 2A, the crowns 101 enter the opening.

Thus, the stapler removal device 1G includes a guide portion 4A, thereby making it easier to set the booklet P to a predetermined position where the staplers 100 at multiple locations along the fold P1 of the booklet P can be removed. Furthermore, the stapler removal device 1G includes indicator portions 43A and 44A in the guide portion 4A, thereby making it even easier to set the booklet P to a predetermined position where the staplers 100 at multiple locations along the fold P1 of the booklet P can be removed.

When the handle 523G of the stapler removal device 1G is operated by hand, the lever 522G rotates with the shaft 520G as a fulcrum, and each supporting part 501C rotates with the shaft 520G as a fulcrum, thereby each wedge part 500C rotates from the standby position to the direction of the crown part 101 of each stapler 100 after binding the booklet P, and enters between the crown part 101 and the booklet P.

After each wedge 500C enters between the crown 101 of each stapler 100 and the booklet P, when the wedge 500C rotates in the direction of moving from the standby position to the actuating position, the force in the direction of pulling the stapler 100 out of the booklet P acts on the stapler 100. As shown in FIG. 17D, the foot 102 is lifted while being pulled out of the booklet P. After the booklet P is removed, the stapler 100 falls to the waste staple insertion hole 7A by its own weight.

The stapler removal device 1G rotates the wedge portion 500C to the actuation position for pulling out the stapler 100 from the booklet P. When the handle portion 523G is operated by hand, the lever 522G rotates in the opposite direction using the shaft 520G as a fulcrum, and each wedge portion 500C rotates from the actuation position to the standby position.

Thus, the stapler removal device 1G enables the booklet P, which is bound by the staplers 100 at multiple locations along the fold P1, to be set in a closed state in the form of a two-fold book binding that is not opened, so as to remove each stapler 100.

The stapler removal device 1H corresponds to two places along the fold P1, for example, of the booklet P bound by the stapler 100. Moreover, the guide part 4H that guides the fold P1 of the booklet P to the alignment part 2A is a structure in which the first guide part 41H and the second guide part 42H are divided into two parts, respectively, so that the intervals of the staplers 100 at the two places are different.

In addition, the guide portion 4H is provided with an indicator portion 43H on the surface facing each second guide portion 42H in each first guide portion 41H, and an indicator portion 44H on the surface facing each first guide portion 41H in each second guide portion 42H.

As shown in FIG. 18A and FIG. 18C , the first guide portion 41H and the second guide portion 42H are structures that are linked and switched along the longitudinal spacing of the alignment portion 2A. Thus, the spacing of a pair of indicator portions 43H and the spacing of a pair of indicator portions 44H can be adjusted to match the spacing of the binding position of the stapler 100.

Furthermore, the stapler removal device 1H includes an opening portion (not shown) into which the crown portion 101 of the stapler 100 after binding the booklet P enters when the fold P1 of the booklet P contacts the alignment portion 2A. The structure of the opening portion may be an opening that is provided in conjunction with the switching of the longitudinal intervals between the first guide portion 41H and the second guide portion 42H, or an opening of a length that the stapler 100 at multiple locations along the fold P1 of the booklet P enters.

The removal part 5H for pulling out the staple 100 from the booklet P includes: a plurality of wedge assembly bodies 50C, which are switched along the longitudinal intervals of the alignment part 2A in accordance with the binding position of the staple 100; and a driving part 51H, which links each wedge assembly body 50C to drive it. The wedge assembly body 500C includes a wedge part 500C and a supporting part 501C on which the wedge part 500C is installed.

The removal portion 5H is a structure in which a plurality of support portions 501C are installed on a shaft 520H, with a longitudinal interval along the alignment portion 2A to be switched in accordance with the binding position of the stapler 100. As shown in FIG. 18B and FIG. 18D , the wedge assembly 50C is linked to the switching of the interval between the first guide portion 41H and the second guide portion 42H, and the interval of the support portion 501C is switched.

The driving part 51H includes a lever 522H rotatably mounted on a shaft 520H having a plurality of supporting parts 501C. The end of the lever 522H is supported by the shaft 520H and rotates in conjunction with the shaft 520H. In addition, the lever 522H includes a hand-operated handle 523H at the end of the other side.

The stapler removal device 1H allows the booklet P in a closed state, with the fold P1 after being bound by the stapler 100 facing downward, to enter between the first guide part 41H and the second guide part 42H constituting the guide part 4A.

The staple removal device 1H is such that when the booklet P enters between the first guide portion 41H and the second guide portion 42H, the fold P1 of the booklet P becomes along the longitudinal direction of the alignment portion 2A, and the fold P1 of the booklet P is guided to a position that contacts the alignment portion 2A.

In addition, at multiple locations along the fold P1 of the booklet P, in this example, at two locations along the fold P1, the interval between the first guide portion 41H and the second guide portion 42H is switched in accordance with the interval between the crown portions 101 of the stapler 100 after binding the booklet P, whereby, when the fold P1 of the booklet P contacts the alignment portion 2A, the crown portion 101 enters the opening portion after the position of each crown portion 101 is aligned with the opening portion not shown.

Thus, the stapler removal device 1H includes the guide portion 4H, which makes it easier to set the booklet P to a predetermined position where the stapler 100 can be removed after being bound at multiple locations along the fold P1 of the booklet P. Furthermore, the stapler removal device 1H includes the indicator portions 43H and 44H in the guide portion 4H, which makes it easier to set the booklet P to a predetermined position where the stapler 100 can be removed after being bound at multiple locations along the fold P1 of the booklet P when the binding position of the stapler 100 is different.

When the handle 523H is operated by hand, the lever 522H rotates with the shaft 520H as a fulcrum, and each supporting part 501C rotates with the shaft 520H as a fulcrum, thereby each wedge part 500C rotates from the standby position to the direction of the crown part 101 of each stapler 100 after binding the booklet P, and enters between the crown part 101 and the booklet P.

After each wedge 500C enters between the crown 101 of each stapler 100 and the booklet P, when the wedge 500C rotates in the direction of moving from the standby position to the actuating position, the force in the direction of pulling the stapler 100 out of the booklet P acts on the stapler 100, and the foot 102 is lifted while being pulled out of the booklet P. After the booklet P is removed, the stapler 100 falls to the waste staple insertion hole 7A by its own weight.

The stapler removal device 1H rotates the wedge portion 500C to the actuation position for pulling out the stapler 100 from the booklet P. When the handle portion 523H is operated by hand, the lever 522H rotates in the opposite direction using the shaft 520H as a fulcrum, and each wedge portion 500C rotates from the actuation position to the standby position.

Thus, the stapler removal device 1H enables the booklet P, which is bound by the staplers 100 at multiple locations along the fold P1, to be set in a closed state in the form of a two-fold book that is not opened, and each stapler 100 can be removed. Moreover, even if the binding positions of the staplers 100 along the fold P1 are different, it can correspond. Although the manual operation example is described here, it can also be automatically configured as in the first embodiment. Moreover, although the wedge portion is rotated as in the first embodiment, the wedge portion can also be configured to move linearly as in the first embodiment. Moreover, the booklet can also be set in the horizontal direction as in the second embodiment.
