The present disclosure relates to a stapler for binding a plurality of sheets with a staple, a post-processing apparatus on which a stapler is mounted, and an image forming system in which the post-processing apparatus is connected to an image forming apparatus.
In an electric stapler used in a post-processing apparatus, there is suggestion of a technique in which a staple having a staple foot of a length capable of binding the maximum number of sheets to be assumed is stored, and in a case where the number of sheets to be bound is small or the like, the staple foot is cut and bound.
In the related-art stapler mounted on the post-processing apparatus, the cut staple storage unit is provided on the post-processing apparatus side, the cut staple is temporarily stored in a discharge path of the cut staple provided in the stapler, the stapler is moved to the position of the cut staple storage unit, and the cut staple is discharged from the stapler to the cut staple storage unit (see, for example, Japanese Utility Model Application Publication No. 63-72001 and Japanese Unexamined Patent Application Publication No. 2006-26859).
Further, there is suggestion of a technique of providing a staple storage unit in a staple cartridge which stores a staple (see, for example, Japanese Unexamined Patent Application Publication No. 2006-168185).
In the related art, since it is necessary to move the stapler to a position of the cut staple storage unit provided on the side of the post-processing apparatus in order to recover the cut staple, the productivity of a booklet for binding the sheet with the staple decreases. When the number of cut staples temporarily stored in a discharge passage provided in the stapler is large, in a state in which the stapler is moved to the position of the cut staple storage unit, there was a possibility that the cut staple may leak into the post-processing apparatus from the discharge passage.
In a configuration having the cut staplecut staple storage unit in the staple cartridge, a storable amount of the cut staples is small, and thus it is necessary to recover the cut staples before the staples are run out. In a case where the cut staple storage unit is enlarged to increase a storable amount of the cut staple, it is necessary to reduce the storage part of the staple in order that the magnitude of the entire staple cartridge maintains the same as existing magnitude. For this reason, problems occur that an amount of the staple which is loaded in the staple cartridge is reduced, and the number of binding times of the staple decreases. In order to secure the storable amount of the staple, and to increase the storable amount of the cut staple, it is necessary to enlarge the staple cartridge, which causes a problem that the entire stapler is enlarged.
The present disclosure is made to solve the problems, and an object thereof is to provide a stapler which can store a predetermined amount of cut staples and easily recovers the cut staples, a post-processing apparatus mounted with the stapler, and an image forming system in which the post-processing apparatus is connected to an image forming apparatus.
A stapler may comprise a staple cartridge in which a staple is stored, a storage unit to which the staple cartridge is attached to be detachable, a staple ejecting unit which ejects out the staple to penetrate a paper sheet, a cutting unit which cuts a staple leg of the staple penetrating the paper sheet, a binding unit which binds the paper sheet by bending the staple leg of the staple penetrating the paper sheet, a cut staple storage unit which stores a cut staple that is cut by the cutting unit, and a discharge unit through which the cutting unit and the cut staple storage unit communicate with each other to guide the cut staple to the cut staple storage unit. The cut staple storage unit may be attachable to and detachable from the stapler.
A post-processing apparatus may comprise the stapler. The post-processing apparatus may perform post-processing on a paper sheet on which an image is formed.
An image forming system may comprise an image forming apparatus which forms an image on a paper sheet and outputs the image, and the post-processing apparatus which is connected to the image forming apparatus and performs a post process on the paper sheet.
In the present disclosure, the cut staple is stored in the cut staple storage unit provided in the stapler. The recovery of the cut staple is performed when the cut staple storage unit is released from the stapler.
In the present disclosure, the cut staple storage unit is provided in the stapler, and thus the cut staple can be stored in the cut staple storage unit regardless of the position of the stapler in the post-processing apparatus. Therefore, it is not necessary to move the stapler to a specific position in order to recover the cut staple, and the productivity of a book obtained by binding the paper sheet with the staple is improved.
The cut staple storage unit is configured to be detachable from the stapler, and the recovery of the cut staple is performed when the cut staple storage unit is released from the stapler. Therefore, it is possible to suppress faults such as a drop of the cut staple inside the post-processing apparatus at the time of recovering the cut staple.
Embodiments of a stapler of the present disclosure, a post-processing apparatus on which a stapler is mounted, and an image forming system equipped with the post-processing apparatus will be described below with reference to the drawings.
The image forming system 500A according to the present embodiment includes an image forming apparatus 501A, and a post-processing apparatus 502A which is connected to the image forming apparatus 501A and is capable performing of at least one type of processing. The image forming apparatus 501A forms and outputs an image on a sheet P that is fed from a sheet feeding unit (not illustrated) inside or outside the apparatus. In this example, the image forming apparatus 501A forms an image on the sheet P, by forming an electrostatic latent image by scanning exposure, by developing an electrostatic latent image with toner, and by transferring and fixing the toner to sheet and the like.
The post-processing apparatus 502A of the present embodiment includes any one of the stapler 1 of each embodiment to be described later in a binding unit 503A. The binding unit 503A includes a loading unit 504A that stacks the sheet P output from the image forming apparatus 501A.
<Operational Example of Binding Sheet with Staple>
As the staple crown 11A is pressed, as illustrated in
As illustrated in
The stapler 1A of the first embodiment is equipped with a staple ejecting unit 2A which supplies and ejects the staple 10A, and a binding unit 3A which cuts the staple leg 12A of the staple 10A illustrated in
The staple ejecting unit 2A is an example of a staple ejecting unit and includes a storage unit 20A to which a staple cartridge 100A as a staple storage unit in which the staple 10A is stored is detachably attached, a feeding unit 21A which feeds the staple 10A from the staple cartridge 100A, and a ejecting unit 22A which ejects the staple 10A into the sheet P.
In the present example, the staple 10A is provided as a staple sheet 101A in which a plurality of linear staples 10A are integrated by adhesion, and the plurality of staple sheets 101A are stacked and stored in the staple cartridge 100A. The ejecting unit 22A forms the second or third staple 10A in conjunction with the operation of ejecting the one staple 10A of the foremost end in the conveying direction of the staple sheet 101A. The staple cartridge 100A may be supplied in a form in which the staple sheet 101A is stored in a detachable refill.
The binding unit 3A is an example of a binding unit, and includes a cut unit 30A that cuts the staple leg 12A of the staple 10A penetrating the sheet P at a predetermined length, and a clinch unit 31A which folds the staple leg 12A of the staple 10A that passes through the sheet P and is cut to a predetermined length in the direction of the sheet P.
The stapler 1A is provided with a sheet pinching unit 4A which pinches the sheet P between the staple ejecting unit 2A and the binding unit 3A. The sheet pinching unit 4A is provided on one side of the stapler 1A provided with the ejecting unit 22A of the staple ejecting unit 2A and the clincher unit 31A of the binding unit 3A.
As illustrated in
As illustrated in
In order to enable the binding position of the sheet P by the staple 10A to be positioned between the ejecting unit 22A and the clincher unit 31a, the sheet pinching unit 4A has a shape in which three directions of the front side of the stapler 1A and both side surfaces of the stapler 1A are open.
The stapler 1A includes a feeding unit 21A and an ejecting unit 22A of the staple ejecting unit 2A, a binding unit 3A, and a driving unit 5A that drives the cut unit 30A of the binding unit 3A, and the clincher unit 31A.
The ejecting unit 5A includes a cam 51A that is driven by a motor 50A provided in the staple ejecting unit 2A, and a link unit 52A that transmits the operation of the cam 51A to each unit.
When the operation of the cam 51A is transmitted to the binding unit 3A via the link unit 52A or the like, the stapler 1A relatively moves in a direction in which the staple ejecting unit 2A and the binding unit 3A come into contact with and separate from each other. In this example, the binding unit 3A moves in a direction in which the binding unit 3A moves in the direction of coming into contact with and separating from the staple ejecting unit 2A with a rotational operation about the shaft 32A as a fulcrum.
In the operation of the cam 51A rotating in one direction, the stapler 1A moves in a direction in which the binding unit 3A approaches the staple ejecting unit 2A, and pinches the sheet P with the sheet pinching unit 4A at a predetermined timing. In addition, in the operation in which the cam 51A further rotates in one direction, the stapler 1A moves in a direction in which the binding unit 3A moves away from the staple ejecting unit 2A at a predetermined timing, thereby releasing the pinching of the sheet P by the sheet pinching unit 4A.
In addition, in the operation in which the operation of the cam 51A is transmitted to the feeding unit 21A and the ejecting unit 22A via the link unit 52A and the like, and the cam 51A rotates in one direction, the stapler 1A feeds the staple 10A stored in the staple cartridge 100A by the feeding unit 21A, and drives the foremost tip of the fed staple 10A into the sheet P pinched by the sheet pinching unit 4A by the ejecting section 22A, so that the staple leg 12A of the staple 10A penetrates the sheet P. Also, the second or third staple 10A is molded.
Furthermore, in the operation in which the operation of the cam 51A is transmitted to the cut unit 30A and the clincher unit 31A via the link unit 52A and the like, and the cam 51A rotates in one direction, in the stapler 1A cuts the staple leg 12A of the staple 10A penetrating the sheet P by the cut unit 30A at a predetermined length, and folds the staple leg 12A of the staple 10A cut to a predetermined length with the clincher unit 31A.
The stapler 1A has a cut staple storage unit 6A which stores the cut staple 13A that is cut by the cut unit 30A. The cut staple storage unit 6A is detachably attached to the stapler 1A on the back side of the stapler 1A opposite to the side on which the sheet pinching unit 4A is provided.
The cut staple storage unit 6A includes two recovery passages 60AL and 60AR. When attached to the stapler 1A, the two recovery passages 60AL and 60AR are disposed on both sides of the storage unit 20A to block the attachment and detachment path of the staple cartridge 100A to be attached to and detached from the storage unit 20A.
The cut staple storage unit 6A has a size capable of storing all of the cut staples 13A even when the staple leg 12A of the number of staples 10A capable of being stored in the staple cartridge 100A is cut with the maximum length.
Further, regardless of the position of the stapler 1A in the post-processing apparatus 502A, the cut staple storage unit 6A is configured so that the main body of the cut staple storage unit 6A is located below one or both of the recovery passage 60AL or the recovery passage 60AR, regardless of the position of the stapler 1A in the post-processing apparatus 502A.
The stapler 1A includes a discharge passage 33A which guides the cut staple 13A cut by the cut unit 30A to the cut staple storage unit 6A in the binding unit 3A. In the present embodiment, one discharge passage 33A communicating with the cut unit 30A is divided into two discharge passages 33AL and 33AR and are disposed on both left and right sides of the storage unit 20A to block the attachment and detachment path of the stable cartridge 100A attached to and detached from the storage unit 20A.
In the stapler 1A, the discharge port 34AL of one discharge passage 33AL communicates with the recovery port 61AL of one recovery passage 60AL of the cut staple storage unit 6A, and the discharge port 34AR of the other discharge passage 33AR communicates with the recovery port 61AR of the other recovery passage 60AR of the cut staple storage unit 6A.
As a result, the cut staple 13A passing through one discharge passage 33AL from the cut unit 30A is stored in the cut staple storage unit 6A from the recovery port 61AL through the recovery passage 60AL. The cut stable 13A passing through the other discharge passage 33AR from the cut unit 30A is stored in the cut staple storage unit 6A through the recovery passage 60AR from the recovery port 61AR.
In the discharge passage 33A, at least one of the discharge passage 33AL and the discharge passage 33AR is configured such that the discharge ports 34AL and 34AR are lower than the cut unit 30A, regardless of the position of the stapler 1A in the post-processing apparatus 502A.
By providing the discharge passages 33A (33AL, 33AR) in the binding unit 3A, the discharge passage 33A (33AL, 33AR) moves by the rotational operation of the binding unit 3A with the shaft 32A as a fulcrum. In contrast, the cut staple storage unit 6A does not move with respect to the binding unit 3A when attached to the staple ejecting unit 2A.
Therefore, the discharge port 34AL of one discharge passage 33AL and the discharge port 34AR of the other discharge passage 33AR are disposed in the vicinity of the shaft 32A, thereby suppressing the quantity of movement of the discharge port 34AL and 34AR in the rotational operation of the binding unit 3A with the shaft 32A as a fulcrum to be small level.
Further, the discharge port 34AL of one discharge passage 33AL enters one recovery port 61AL of the cut staple storage unit 6A, and the discharge port 34AL can move within the range of opening of the recovery port 61AL. Similarly, the discharge port 34AR of the other discharge passage 33AR enters the other recovery port 61AR of the cut staple storage unit 6A, and the discharge port 34AR can move within the range of opening of the recovery port 61AR.
In the conventional stapler mounted on the post-processing apparatus, the cut staple storage unit is provided on the side of the post-processing apparatus, the cut staple is temporarily stored in the discharge passage of the cut staple provided in the stapler, and the stapler is moved to the position of the cut staple storage unit, and the cut staple is discharged from the stapler to the cut staple storage unit.
As described above, in the related art, in order to recover the cut staple, since it is necessary to move the stapler to the position of the cut staple storage unit provided on the side of the post-processing apparatus, the productivity of the booklet for binding the sheet with the staple decreases. When the number of cut staples temporarily stored in the discharge passage provided in the stapler is large, in a state in which the stapler is not moved to the position of the cut staple storage unit, there was a possibility that the cut staple from the discharge passage may leak into the post-processing apparatus.
In contrast, in the stapler 1A according to the first embodiment, by providing the cut staple storage unit 6A in the stapler 1A, it is possible to store the cut staple 13A in the storage unit 6A, regardless of the position of the stapler 1A in the post-processing apparatus 502A. Therefore, there is no need to move the stapler 1A to a specific position in order to recover the cut staple, and the productivity of the booklet for binding the sheet with the staple is improved.
Further, even when the staple leg 12A of the number of staples 10A that can be stored in the staple cartridge 100A is cut with the maximum length, the cut staple storage unit 6A is large enough to store all the cut staples 13A and has a sufficient capacity, and it is unnecessary to recover the staple 13A until the timing of replenishing the staple 10A. Therefore, it is possible to reduce the number of times of recovering the cut staple 13A from the stapler 1A, and it is possible to reduce the number of times of stopping the operation of the image forming system 500A for recovering the cut staple 13A, the productivity of the booklet for binding the sheet with the stable is improved.
In the present example, attachment and detachment of the cut staple storage unit 6A are performed by moving the stapler 1A to the first position Pp1 (attachment/detachment position) illustrated in
In the stapler 1A, the staple cartridge 100A can be attached and detached with the cut staple storage unit 6A attached. Thus, by moving the stapler 1A to the first position Pp1 illustrated in
Further, since the cut staple storage unit 6A is attached to the back side of the stapler 1A, even if the capacity of the cut staple storage unit 6A increases, restriction on the size of the staple cartridge 100A is restrained, it is possible to maintain or increase the number of stored staples 10A, as compared with a configuration not provided with the cut staple storage unit 6A.
As illustrated in
There is a possibility that erroneous detection may occur that the cut staple 13A is full if the bulk increases due to the inclination of the stored cut staple 13A. In the configuration in which the processing is stopped by full load of the cut staple 13A, even if there is still a remaining capacity in the cut staple storage unit 6A, the cut staple 13A cannot be stored and the cut staple storage unit 6A cannot be effectively used. In contrast, since it is possible to suppress the deviation of the cut staple 13A and store the cut staple 13A flattened to a substantially uniform height, erroneous detection or the like caused by offset of the stored cut staple 13A can be suppressed, which makes it possible to effectively use the cut staple storage unit 6A.
As illustrated in
Therefore, even if the stapler 1A moves to any one of the first position Pp1, the second position Pp2 or the third position Pp3 illustrated in
As a result, even if the stapler 1A moves to one of the first position Pp1, the second position Pp2 or the third position Pp3 in the binding operation, it is possible to suppress the cut staple 13A cut by the cut unit 30A from staying in the discharge passage 33AL and the discharge passage 33AR. Further, it is possible to suppress the cut staples 13A discharged from the discharge passage 33AL and the discharge passage 33AR from staying in the recovery passage 60AL and the recovery passage 60AR. Therefore, the cut staple 13A cut with the cut unit 30A can be stored in the cut staple storage unit 6A.
In the operation of binding the sheet P with the stapler 1A, the discharge unit 33AL and the discharge unit 33AR are moved when the binding unit 3A moves by the rotational operation about the shaft 32A as a fulcrum. When the movement quantity of the discharge port of the discharge passage increases, since the recovery port of the cut staple storage unit to which the discharge port is connected needs to be sized to match the movement range of the discharge port, the size of the stapler increase.
In contrast, by arranging the discharge port 34AL of one discharge passage 33AL and the discharge port 34AR of the other discharge passage 33AR in the vicinity of the shaft 32A, it is possible to suppress the movement quantity of the discharge port 34AL and the discharge port 34AR, and it is possible to reduce the size of the stapler 1A.
In addition, the discharge port 34AL of one discharge passage 33AL enters one recovery port 61AL of the cut staple storage unit 6A, and the discharge port 34AL can move within the range of opening of the recovery port 61AL. Similarly, the discharge port 34AR of the other discharge passage 33AR enters the other recovery port 61AR of the cut staple storage unit 6A, and the discharge port 34AR can move within the range of the opening of the recovery port 61AR. As a result, it is possible to suppress leakage of the cut staple 13A to the outside at the connecting portion between the cut staple storage unit 6A and the discharge passage 33A.
As illustrated in
The stapler 1B includes a sheet pinching unit 4B that pinches the sheet P between the staple ejecting unit 2B and the binding unit 3B. The stapler 1B moves in a direction in which the binding unit 3B moves away from and comes into contact with the staple ejecting unit 2B in a rotational operation about the shaft 32B as a fulcrum, and pinches and releases the sheet P with the sheet pinching unit 4B.
The stapler 1B includes a cut unit 30B that cuts the staple leg 12A of the staple 10A penetrating the sheet P at a predetermined length, a cut staple storage unit 6B which stores the cut staple 13A cut with the cut unit 30B, and a discharge passage 33B which guides the cut staple 13A cut with the cut unit 30B to the cut staple storage unit 6B. In the stapler 1B according to the second embodiment, the feeding unit, the ejecting unit, the clincher unit, and the driving unit of the staple 10A are not illustrated, but the stapler 1B may have the same configuration as the stapler 1A of the first embodiment.
The cut staple storage unit 6B is detachably attached to the stapler 1B on the back side of the stapler 1B. When attached to the stapler 1B, the cut staple storage unit 6B has a shape that closes the attachment/detachment path of the staple cartridge 100 B attached to and detached from the storage unit 20B as illustrated in
As illustrated in
In the stapler 1B, the discharge port 34BL of one discharge passage 33BL and one recovery port 61BL of the cut staple storage unit 6B communicate with each other, and the discharge port 34BR of the other discharge passage 33BR and the other recovery port 61BR of the cut staple storage unit 6B communicate with each other.
As a result, the cut staple 13A passing through the one discharge passage 33BL from the cut unit 30B is stored in the cut staple storage unit 6B from the recovery port 61BL. Further, the cut staple 13A passing from the cut unit 30B through the other discharge passage 33BR is stored in the cut staple storage unit 6B from the recovery port 61BR.
At least one of the discharge passage 33BL and the discharge passage 33BR of the discharge passage 33B is configured such that the discharge ports 34BL and 34BR are lower than the cut unit 30B, regardless of the position of the stapler 1B in the post-processing apparatus 502A. Therefore, the cut staple 13A cut with the cut unit 30B is suppressed from staying in the cut unit 30B, the discharge passage 33BL, and the discharge passage 33BR, and is configured to be stored in the cut staple storage unit 6B.
In the discharge passage 33B, the discharge port 34BL of one discharge passage 33BL and the discharge port 34BR of the other discharge passage 33BR are arranged in the vicinity of the shaft 32B. As a result, the quantity of movement of the discharge ports 34BL and 34BR in the rotational operation of the binding unit 3B with the shaft 32B as the fulcrum is suppressed, and it is possible to reduce the size of the plow 1B.
Further, the discharge port 34BL of one discharge passage 33BL enters one recovery port 61BL of the cut staple storage unit 6B, and the discharge port 34BL is disposed within the range of the opening of the recovery port 61BL. Similarly, the discharge port 34BR of the other discharge passage 33BR enters the other recovery port 61BR of the cut staple storage unit 6B, and the discharge port 34BR is movable within the range of the opening of the recovery port 61BR. As a result, it is possible to suppress the leakage of the cut staple 13A to the outside at the connecting portion between the cut staple storage unit 6B and the discharge passage 33B.
In the stapler 1B according to the second embodiment, the attachment and detachment of the staple cartridge 100B is performed in a state in which the cut staple storage unit 6B is detached from the stapler 1B. Therefore, when replenishing the staple 10A, an operation of attaching and detaching the cut staple storage unit 6B is indispensable, and the recovery of the cut staple 13A can be performed reliably at the timing of replenishing the staple 10A when there is no staple 10A.
As illustrated in
The stapler 1C includes a sheet pinching unit 4C which pinches the sheet P between the staple ejecting unit 2C and the binding unit 3C. The stapler 1C moves in a direction in which the binding unit 3C comes into contact with and separates from the staple ejecting unit 2C in a rotational operation about the shaft 32 C as a fulcrum, and pinches and releases the sheet P by the sheet pinching unit 4C.
The stapler 1C includes a cut unit 30C which cuts the staple leg 12A of the staple 10A penetrating the sheet P with a predetermined length, a cut staple storage unit 6C which stores the cut staple 13A cut by the cut unit 30C, and a discharge passage 33C which guides the cut staple 13A cut by the cut unit 30C to the cut staple storage unit 6C. In the stapler 1C according to the third embodiment, the feeding unit, the ejecting unit, the clincher unit, and the driving unit of the staple 10A are not illustrated, but the stapler 1C may have the same configuration as the stapler 1A of the first embodiment.
The cut staple storage unit 6C is detachably attached to the stapler 1C on the upper surface side of the stapler 1C. The cut staple storage unit 6C may be detachably attached to the binding unit 3C or may be detachably attached to the staple ejecting unit 2C. In addition, the cut staple storage unit 6C may be attached to the staple cartridge 100C, or may be configured to detach the cut staple storage unit 6C from the stapler 1C by attaching and detaching the staple cartridge 100C.
The discharge passage 33C is provided in the binding unit 3C and communicates with the cut unit 30C, and the recovery port 61C of the cut staple storage unit 6C communicates with the discharge port 34C. As a result, the cut staple 13A passing from the cut unit 30C through the discharge passage 33C is stored in the cut staple storage unit 6C from the recovery port 61C.

The cut staple storage unit 6Mfa is not limited to a configuration in which the cut staple storage tank 60MM rotates with the shaft 60MMD provided on the recovery passage 60MR side as a fulcrum to be opened. For example, the cut staple storage unit 6Mfa may be configured such that the cut staple storage tank 60MM rotates with the shaft 60MMD provided on the recovery passage 60ML side as a fulcrum to be opened. For example, the cut staple storage tank 60MM includes the claw 60MMA and the manipulation unit 60MMB which protrude from both sides of the recovery passages 60ML and 60MR respectively. The cut staple storage unit 6Mfa may have the holes 60MMC near the recovery passages 60ML and 60MR respectively.
Similarly with the cut staple storage unit 6Mf illustrated in
As illustrated in
The stapler 1Mg includes the paper sheet pinching unit 4M nipping the paper sheet P between the staple ejecting unit 2M and the binding unit 3M. The stapler 1Mg nips and releases the paper sheet P with the paper sheet pinching unit 4M when the binding unit 3M moves in a direction approaching to or departing from the staple ejecting unit 2M by a rotation operation with the shaft 32M as a fulcrum.
The stapler 1Mg includes the cutting unit 30M which cuts the staple leg 12A of the staple 10A penetrating the paper sheet P to the predetermined length, a cut staple storage unit 6Mg which stores the cut staple 13A cut by the cutting unit 30M, and the discharge passage 33M which guides the cut staple 13A cut by the cutting unit 30M to the cut staple storage unit 6Mg. While the feeding unit of the staple 10A, the ejecting unit, the clincher unit, and the driving unit are not illustrated, the stapler 1Mg of the sixteenth embodiment may have the same configuration as the stapler 1A of the first embodiment.
The cut staple storage unit 6Mg includes two recovery passages 60ML and 60MR. When the cut staple storage unit 6Mg is attached to the stapler 1Mg, the two recovery passages 60ML and 60MR are disposed such that the detachable path of the staple cartridge 100M is not blocked.
The cut staple storage unit 6Mg is attached on the back surface of the staple ejecting unit 2M so as to be detachable from the stapler 1Mg. A shaft protrusion 70Mg is inserted to the receiving unit (not illustrated) of the stapler 1Mg, and the cut staple storage unit 6Mg is operated to be attached and detached to/from the stapler 1Mg by a rotation operation with the shaft protrusion 70Mg as a fulcrum. The cut staplecut staple storage unit 6Mg is released from the stapler 1Mg by uncoupling the shaft protrusion 70Mg from the stapler 1Mg. The cut staple storage unit 6Mg includes a locking claw 71Mg locked to the stapler 1Mg, and an manipulation unit 72Mg which is provided in the locking claw 71Mg, and releases the locking of the locking claw 71Mg.
In the stapler 1Mg, the discharge port 34ML of one discharge passage 33ML communicates with a recovery port 61ML of one recovery passage 60ML of the cut staple storage unit 6Mg. The discharge port 34MR of the other discharge passage 33MR communicates with a recovery port 61MR of the other recovery passage 60MR of the cut staple storage unit 6Mg (not illustrated).
The cut staple storage unit 6Mg includes a cut staple storage tank 60MN which stores the cut staple 13A. The cut staple storage tank 60MN has a shape of protruding to the opposite side of the staple ejecting unit 2M. The cut staple storage unit 6Mg includes a lid 83MN, which opens and closes the hole 60MG, on the side surface of the recovery port 61ML of the cut staple storage tank 60MN. The lid 83MN opens and closes the hole 60MG by moving in a direction away from or closer to the recovery port 61ML.
The lid 83MN has a claw 83MNA which protrudes toward the recovery port 61ML. The recovery passage 60ML has the hole 83MNC near the cut staple storage tank 60MN. When the hole 60MG is closed, the claw 83MNA enters the hole 83MNC, and the cut staple storage tank 60MN is opened by uncoupling the claw 83MNA from the hole 83MNC.
The lid 83MN includes a regulating unit 92M which regulates the lid 83MN not to be attached to the staple ejecting unit 2M when the lid 83MN is not closed sufficiently. The regulating unit 92M protrudes from the lid 83MN toward the staple ejecting unit 2M. The staple ejecting unit 2M has a recess 2MA which the regulating unit 92M enters in a state where the lid 83MN is closed sufficiently. The staple ejecting unit 2M has a projection 2MB in a position near the recess 2MA opposite to the position of the binding unit 3M.
In the stapler 1Mg of the sixteenth embodiment, the cut staple storage tank 60MN of the cut staple storage unit 6Mg has a shape of protruding to the opposite side of the staple ejecting unit 2M. Therefore, the cut staple storage tank 60MN can be larger volume than the cut staple storage tank 60MM illustrated in
In the stapler 1Mg, in a case where the cut staple storage unit 6Mg is released, the locking claw 71Mg is retreated to release the locking by manipulating the manipulation unit 72Mg. When the cut staple storage unit 6Mg is moved from the staple ejecting unit 2M in a separating direction, the cut staple storage unit 6Mg is released from the stapler 1Mg by a rotation operation with the shaft protrusion 70Mg as a fulcrum.
As illustrated in
With this configuration, the cut staple storage tank 60MN can be opened and closed easily. Therefore, when the cut staple storage unit 6Mg is released from the stapler 1Mg, it is possible to suppress faults such as a drop of the cut staple 13A inside the post-processing apparatus 502A, and to discard the cut staple 13A without any contact.
In a case where the cut staple storage unit 6Mg is attached, the cut staple storage unit 6Mg is pressed in a direction of the staple ejecting unit 2M in a state where the shaft protrusion 70Mg enters the receiving unit (not illustrated) of the stapler 1Mg. Thus, the locking claw 71Mg is locked to the stapler 1Mg by a rotation operation with the cut staple storage unit 6Mg, and the cut staple storage unit 6Mg is attached to the stapler 1Mg as illustrated in
As illustrated in
As illustrated in
With this configuration, in a state where the cut staple storage unit 6Mg is not attached to the stapler 1Mg certainly, the stapler 1Mg does not start an operation. In a state where the cut staple storage unit 6Mg is attached to the stapler 1Mg certainly, the lid 83MN is not opened. For this reason, it is possible to regulate the operation of the stapler 1Mg in a state where the lid 83MN is opened, and it is possible to suppress faults such as a drop of the cut staple 13A inside the post-processing apparatus 502A.
Similarly with the cut staple storage unit 6Mf illustrated in
As described in the thirteenth embodiment, the discharge ports 34ML and 34MR also may be provided with lids. In a case where the discharge ports 34ML and 34MR are provided with the lids, although the cut staple 13A remains in the discharge passage 33M when the cut staple storage unit 6Mg is released from the stapler 1Mg, it can be suppressed that the cut staple 13A is discharged outside the stapler 1Mg.
Similarly with the stapler 1Mg, the stapler 1Mga includes the staple ejecting unit 2M and the binding unit 3M, and includes the paper sheet pinching unit 4M nipping the paper sheet P between the staple ejecting unit 2M and the binding unit 3M.
The stapler 1Mga includes the cutting unit 30M which cuts the staple leg 12A of the staple 10A penetrating the paper sheet P to the predetermined length, a cut staple storage unit 6Mga which stores the cut staple 13A cut by the cutting unit 30M, and the discharge passage 33M which guides the cut staple 13A cut by the cutting unit 30M to the cut staple storage unit 6Mg. Similarly with the cut staple storage unit 6Mg illustrated in
The stapler 1Mga and the post-processing apparatus 502A include a lid detection unit 94M. The lid detection unit 94M includes a movable unit 95M and a sensor 96M detecting the movable unit 95M.
The movable unit 95M is provided in the lid 83MN to protrude from a surface of the cut staple storage unit 6Mga on the staple ejecting unit 2M side. The movable unit 95M moves together with an operation of opening and closing the hole 60MG by the lid 83MN. By detecting the presence/absence of the movable unit 95M optically, the sensor 96M detects whether the cut staple storage unit 6Mga is attached to the stapler 1Mga in a state where the lid 83MN is closed. In a state where the lid 83MN is closed, and the cut staple storage unit 6Mga is attached to the stapler 1Mga, the sensor 96M is provided in a position of detecting the movable unit 95M.
As illustrated in
As illustrated in
Whether the cut staple storage unit 6Mga is attached to the stapler 1Mga can be detected certainly in a state where the lid 83MN is closed. Thus, without the operation of the stapler 1Mga in a state where the lid 83MN is opened, it is possible to suppress faults such as a drop of the cut staple 13A inside the post-processing apparatus 502A. A detection of whether the lid 83MN is closed, and a detection of whether the cut staple storage unit 6Mga is present can be performed using the same detection unit.
Similarly with the cut staple storage unit 6Mg, the cut staple storage unit 6Mgb includes two recovery passages 60ML and 60MR When the cut staple storage unit 6Mgb is attached to the stapler 1Mg as illustrated in
Similarly with the cut staple storage unit 6Mg illustrated in
The cut staple storage unit 6Mgb includes a cut staple storage tank 60MNA which stores the cut staple 13A. In the cut staple storage unit 6Mgb, the lid 83MG is provided on the surface, on which the cut staple storage tank 60MNA is the stapler 1Mg. The lid 83MG opens and closes the hole 60MGA with the shaft 66MG as a fulcrum.
The lid 83MG has the claw 83MGA, and the cut staple storage tank 60MNA has the hole 83M cc. When the lid 83MG closes the hole 60MGA, the claw 83MGA enters the hole 83M cc. When the lid 83MG is opened by uncoupling the claw 83MGA from the hole 83M cc, it is possible to discard the cut staple 13A from the cut staple storage tank 60MNA.
As illustrated in
Similarly with the cut staple storage unit 6Mg illustrated in
Similarly with the cut staple storage unit 6Mg illustrated in
The lid 83MN has the claw 83MNA which protrudes toward the recovery port 61ML. The recovery passage 60ML has the hole 83MNC. When the lid 83MN is closed, the claw 83MNA enters the hole 83MNC When the lid 83MN is opened by uncoupling the claw 83MNA from the hole 83MNC, the cut staple 13A can be discarded from the hole 60MG.
The cut staple storage unit 6Mgc is attached on the back surface of the staple ejecting unit 2M so as to be detachable from the stapler 1Mg. The cut staple storage unit 6Mgc enters the receiving units 119MgL and 119MgR provided in the lower portion of the stapler 1Mg, and is operated to be attached and detached to/from the stapler 1Mg by a rotation operation with the shaft protrusions 70MgbL and 70MgbR as a fulcrum.
In this example, a regulating unit 92Mg which regulates the rotation of the cut staple storage unit 6Mgc is provided in the stapler 1Mg. The regulating unit 92Mg has a locking unit 92MgA which locks the locking claw 71Mgb provided near the recovery port 61ML of the recovery passage 60ML, the shaft 92MgB which is a fulcrum of the rotation of the locking unit 92MgA, and the manipulation unit 92MgC which rotates the locking unit 92MgA.
As illustrated in
In a case where the cut staple storage unit 6Mgc is released from the stapler 1Mg, the manipulation unit 92MgC is manipulated to rotate the locking unit 92MgA with the shaft 92MgB as a fulcrum, and to release the locking of the locking unit 92MgA with respect to the locking claw 71Mgb. By rotating the receiving units 119MgL and 119MgR in the opposite direction of the arrow of
Since the locking unit 92MgA is locked to the locking claw 71Mgb, it can be suppressed that the cut staple storage unit 6Mgc is uncoupled from the stapler 1Mg unintentionally, and the stapler 1Mg can be used in a state where the cut staple storage unit 6Mgc is attached reliably to the stapler 1Mg.
Even in a state where the lid 83MN is opened as illustrated in
