20200406646
The present application is based on, and claims priority from JP Application Serial Number 2019-121900, filed Jun. 28, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a medium processing apparatus, a loading apparatus, and a medium loading method.
JP-A-2017-65842 discloses a medium processing apparatus capable of loading various types and sizes of paper discharged from a discharge port of a printing apparatus. A receiving sheet for loading discharged paper can be wound so that a user can change a length of the receiving sheet as an example of a sheet-like supporting member, depending on a type and a size of the paper.
Both ends of a top rod as an example of a winding shaft around which the receiving sheet is wound are each attached to a tip of a side rod. Base ends of respective two number of the side rods are rotatably attached to a leg portion that supports a printer portion as an example of a housing. By rotating the two side rods at a desired angle, it is possible to change a position of the winding shaft.
In the medium processing apparatus described in JP-A-2017-65842, when changing a winding amount of the sheet-like supporting member such as the receiving sheet, in order to suppress twisting or wrenching in the winding shaft that winds the sheet-like supporting member, it is desirable to simultaneously operate the two side rods. However, a size of the housing of the printing apparatus is large, and thus it is very difficult to operate the angle of the two side rods simultaneously. Thus, there is a demand for a configuration that can suppress external force loads such as twisting force and wrenching force acting on the winding shaft due to position shift of parts that support both end portions of the winding shaft respectively.
A medium processing apparatus for solving the above-described problems includes, a printer provided with a discharge unit for discharging a processed medium, a supporting member having a sheet-like shape and fixed, in part, to the printer, and moreover configured to support the medium discharged from the discharge unit, and a winding unit configured to wind the supporting member and move with respect to the printer, wherein the winding unit includes a winding shaft to which one end of the supporting member is attached, a rotation mechanism including a winding mechanism rotating the winding shaft in a direction of winding the supporting member and a stop mechanism configured to stop the winding shaft, in a first state in which a length of the supporting member unwound from the winding shaft is a first unwind amount, and in a second state in which a length of the supporting member unwound from the winding shaft is a second unwind amount that is greater than the first unwind amount, a first case positioned at one outer side of the supporting member in an axial direction of the winding shaft and rotatably supporting the winding shaft, a second case positioned at another outer side of the supporting member in the axial direction and rotatably supporting the winding shaft, and a placement portion that, when the winding unit is placed at a flat surface, contacts the flat surface.
A loading apparatus for solving the above-described problems is a loading apparatus that includes, a supporting member having a sheet-like shape and fixed, in part, to a printer and used and moreover configured to support a medium discharged from a discharge unit of the printer, and a winding unit configured to wind the supporting member, wherein the winding unit includes a winding shaft to which one end of the supporting member is attached, a rotation mechanism including a winding mechanism for rotating the winding shaft in a direction of winding the supporting member and a stop mechanism configured to stop the winding shaft, in a first state in which a length of the supporting member unwound from the winding shaft is a first unwind amount and in a second state in which a length of the supporting member unwound from the winding shaft is a second unwind amount that is greater than the first unwind amount, a first case positioned at one outer side of the supporting member in an axial direction of the winding shaft and rotatably supporting the winding shaft, a second case positioned on another outer side of the supporting member in the axial direction and rotatably supporting the winding shaft, and a placement portion that, when the winding unit is placed at a flat surface, contacts the flat surface.
A media loading method for solving the above-described problem is a medium loading method for loading a processed medium discharged from a discharge unit of a printer with use of a loading apparatus including the winding unit and the supporting member in the medium processing apparatus, wherein the printer includes a support shaft at which the supporting member is hung and which supports the supporting member that is hung, and a pair of support shaft holding members that hold both ends of the support shaft respectively and are rotatably attached to the printer, the method including fixing a part of the supporting member unwound from the winding unit to the printer, and, in a direction in which the printer discharges the medium after printing, placing the winding unit in such a way that the support shaft is interposed between the winding unit and a position where the part of the supporting member is fixed to the printer, so as to bring the supporting member unwound from the winding unit into a state of being hung at the support shaft that is positioned higher than the winding unit, and adjusting an angle of the support shaft holding member to change a position of the support shaft, thereby changing a posture of the supporting member at which the medium is loaded.
An exemplary embodiment of a medium processing apparatus will be described below with reference to the drawings. The medium processing apparatus includes a printer and a winding type stacker unit that is an example of a loading apparatus, and is configured by a user attaching the winding type stacker unit to the printer.

The printer 11 has predetermined lengths as a width, a depth, and a height, in a state of being installed at a use location. Assuming that the printer 11 is installed on a horizontal plane, a direction of gravity is indicated by a Z-axis. At this time, a width direction and a depth direction of the printer 11 are substantially horizontal. The depth direction of the printer 11 is indicated by a Y-axis. The width direction of the printer 11 is indicated by an X-axis intersecting the Y-axis and the Z-axis. Thus, the X-axis, the Z-axis, and the Y-axis serve as coordinate axes indicating lengths of a width, a height, and a depth, respectively.

The printer 11 is installed on a floor surface 91 by the four rollers 81a. When the locking lever 81b locks the roller 81a, the printer 11 cannot be moved, and when the lock is released, the printer 11 can be moved.
About Loading Apparatus

The winding unit 60 includes a winding shaft 61 for winding the supporting member 32, and a first case 66 and a second case 76 that rotatably support both end portions of the winding shaft 61, respectively. One end of the supporting member 32 is fixed to the winding shaft 61, and another end (tip end) thereof is fixed to the attachment shaft 36. The supporting member 32 is wound around the winding shaft 61.
The winding unit 60 includes a coupling member 59 that couples the first case 66 and the second case 76 to each other. The first case 66 and the second case 76 are fixed to both ends of the coupling member 59 respectively that extends parallel to the winding shaft 61. The coupling member 59 is one rigid metal plate that does not twist itself. Thus, the coupling member 59 fixes the first case 66 and the second case 76 so as to be non-rotatable with respect to each other in a plane orthogonal to an axis line of the winding shaft 61.

The convex shape, that is the shape of the cross-section of the straight portion 59a, includes a corner shape and a convex curved shape. An angle of a corner of the corner shape is not limited to a right angle, and may be an acute angle or an obtuse angle, or a tip end portion of the corner portion may have a roundness. The straight portion 59a of the present exemplary embodiment is a curved portion formed by performing a bending process for the guide member 59g. The tip end portion of the corner portion of the straight portion 59a is rounded by the bending process. A radius of curvature is a predetermined value within a range of 2 to 8 mm, for example. When the cross-sectional shape of the straight portion 59a is a convex curved shape, an arc shape and an elliptical arc shape are included. Note that, the radius of curvature may be a value outside the range of 2 to 8 mm.

The supporting member 32 is formed as a roll by being wound around the winding shaft 61. As such, the stacker unit 31 is made compact in a state in which the supporting member 32 is wound in a roll shape around the winding shaft 61. The stacker unit 31 is placed at a predetermined position of the leg portion 80, and is compactly stored using a space below the housing 12 with respect to the printer 11. Thus, when the stacker unit 31 is not used, the medium processing apparatus 10 is made compact.

The attachment portion 84 is protrudingly provided upward from a rear upper surface of the base 96. The attachment portion 84 is constituted by a hook that can hook the attachment shaft 36, and facilitates attachment and removal of the winding type stacker unit 31 to and from the printer 11.

The adjuster 43 is used to adjust the inclination angle of the part on which the medium 99 after printing is loaded. The inclination angle of the part of the supporting member 32 on which the medium 99 is loaded is substantially a right angle when the first annular member 43a is attached to the first placement portion 85. When the second annular member 43b is attached to the first placement portion 85, the inclination angle of the part of the supporting member 32 on which the medium 99 is loaded is slightly inclined to have a posture front-downward with respect to the vertical direction. When the third annular member 43c is attached to the first placement portion 85, the inclination angle of the part of the supporting member 32 on which the medium 99 is loaded is further inclined front-downward to a predetermined inclination angle.
As illustrated in
As illustrated in
Further, when changing the length of the supporting member 32 to match a length of the medium 99, the user moves the stacker unit 31. At this time, the user pulls the supporting member 32 in some cases. However, a part of the pulling force is received by the printer 11 via the adjuster 43 pulling the supporting member 32 rear-downward. Thus, the pulling force when the user pulls the supporting member 32 to move the stacker unit 31 is not easily transmitted to the support shaft 86. Even when the user pulls the supporting member 32 somewhat, position shift of the support shaft 86 is less likely to occur.
About Loading Form of Medium
The medium processing apparatus 10 can switch between a forward discharge posture illustrated in
First, with reference to
Since the medium 99 has a curled shape, depending on an angle at which a tip of the medium 99 discharged from the discharge port 13 hits the supporting member 32, there is a possibility that the medium 99 is loaded in a round shape. By adjusting the position of the support shaft 86 and pulling strength by the adjuster 43, the inclination angle of the supporting member 32 at a part where the tip of the medium 99 discharged from the discharge port 13 hits can be changed. By adjusting an angle of the support shaft holding member 87 to change the position of the support shaft 86, a posture of the supporting member 32 receiving the medium 99 is changed.
With the adjuster 43, the angle at which the tip of the medium 99 discharged from the discharge port 13 hits the supporting member 32 can be changed. The angle at which the tip of the medium 99 hits the supporting member 32 is gentle when the first annular member 43a is attached to the first placement portion 85, the angle is slightly steep when the second annular member 43b is attached to the first placement portion 85, and the angle is further steep when the third annular member 43c is attached to the first placement portion 85.
When the medium 99 is loaded on the supporting member 32 in the forward discharge posture, the medium 99 is loaded on the supporting member 32 in a posture in which a printed surface faces upward. The user can retrieve the medium 99 from the front of the printer 11. A back surface that is a surface opposite to the printed surface of the medium 99 contacts the supporting member 32. Since the printed surface does not contact the supporting member 32, quality of a printed image is less susceptible to placement of the medium 99 on the supporting member 32.
Next, with reference to
Since the medium 99 has the curled shape, when the medium 99 discharged from the discharge port 13 slides down rearward on the upper surface of the supporting member 32, there is a possibility that the tip of the medium 99 exceeds a position of the attachment portion 84, and the medium 99 falls from the supporting member 32. By attaching the fourth annular member 44a of each of the two guide strings 44 to a second placement portion 88 protrudingly provided upward from the rear upper surface of the base 96 of the leg portion 80, the two guide strings 44 are stretched in a substantially V shape in a rear view. Thus, at a destination to which the medium 99 discharged from the discharge port 13 slides down rearward on the upper surface of the supporting member 32, the tip of the medium 99 hits the guide string 44 and stops. The guide string 44 that is used to fix the attachment shaft 36 to the base 96 in this manner, functions as a stopper for the medium 99. The guide string 44 prevents the medium 99 sliding down on the supporting member 32, from climbing over the attachment portion 84. Note that, the printer 11 may have a configuration in which the discharge guide 27 is not provided. In this case, in the forward discharge posture, the support shaft 86 is adjusted to a position rearward the discharge port 13, and in the rearward discharge posture, the support shaft 86 is adjusted to a position forward the discharge port 13.
About Rotation Mechanism

The winding mechanism 62a includes the first mating member 63 mated to the winding shaft 61, the disk member 72, and the first main shaft 67 that rotatably supports the first mating member 63 and the disk member 72 via the bearing portion 72b. In the present exemplary embodiment, the winding mechanism 62a includes a flat spiral spring 64 as an example of a drive unit and a rotary biasing portion. Additionally, the stop mechanism 62b is constituted by a ratchet gear 63a and a ratchet claw 65.
As illustrated in
In a state in which the supporting member 32 is wound around the winding shaft 61, the flat spiral spring 64 is in an unwound state. On the other hand, when the winding shaft 61 is rotated in an unwinding direction W1 indicated by an arrow in a counterclockwise direction in
As illustrated in
When the first mating member 63 tries to rotate in the winding direction W2, the ratchet claw 65 digs into the tooth and regulates the rotation. On the other hand, when the first mating member 63 tries to rotate in the unwinding direction W1, the ratchet claw 65 climbs over the tooth to allow the rotation. In other words, the ratchet gear 63a and the ratchet claw 65 intermesh with each other to form a ratchet mechanism that allows the rotation of the winding shaft 61 in the unwinding direction W1 in which the supporting member 32 is unwound, and regulates the rotation of the winding shaft 61 in the winding direction W2 in which the supporting member 32 is wound.

In the present exemplary embodiment, the winding shaft 61 performs axial rotation around the first main shaft 67 and the second main shaft 77 via the respective bearing portions 72b at both end portions thereof. With the first main axis line 67a of the first main shaft 67 supporting the winding shaft 61, and the second main axis line 77a of the second main shaft 77 being aligned with the winding axis line 61a of the winding shaft 61, the first case 66 and the second case 76 are fixed to both ends of the coupling member 59, respectively.
In other words, the first case 66 and the second case 76 are coupled via the coupling member 59, in a state in which the first main axis line 67a as an example of an axis line of the bearing portion 72b that supports the winding shaft 61, and the second main axis line 77a as an example of the axis line of the bearing portion 72b that supports the winding shaft 61 are aligned with each other, and in a state in which rotation in the plane orthogonal to the axis line of the winding shaft 61 is impossible.

Next, action of the medium processing apparatus 10 will be described.
When using the stacker unit 31, the user attaches the supporting member 32 of the stacker unit 31 to the printer 11. Mainly, the supporting member 32 is attached in the two types of postures of the forward discharge posture and the rearward discharge posture. The user determines the posture of the supporting member 32 in consideration of a length and a type of the medium 99, printing quality, and the like.

Compared to this, in the stacker unit 31 of the present exemplary embodiment, as illustrated in
In addition, in a state in which the winding unit 60 is placed on the floor surface 91, particularly when the supporting member 32 is in the forward discharge posture illustrated in
Further, for example, due to weight of the supporting member 32, force in a direction in which the first case 66 overturns in a counterclockwise direction with respect to the Y-axis, and force in a direction in which the second case 76 overturns in a clockwise direction with respect to the Y-axis, act on the winding shaft 61. In other words, the force acts on the first case 66 and the second case 76 such that upper portions thereof overturn so as to approach each other about the Y-axis. However, since the first case 66 and the second case 76 are fixed to each other via the rigid coupling member 59, the first case 66 and the second case 76 do not incline about the Y-axis, due to the weight of the supporting member 32. Thus, in the state in which the user places the winding unit 60 on the floor surface 91, the user does not cause excessive wrenching of the winding shaft 61 in parts that support both ends of the winding shaft 61 respectively.
In addition, in an adjustment operation for the unwind amount of the supporting member 32, or the like, when the supporting member 32 is pulled, force to incline about the Z-axis is applied to the first case 66 and the second case 76. However, since the first case 66 and the second case 76 are fixed to the coupling member 59, even when the supporting member 32 is pulled, the cases do not incline about the Z-axis. As a result, when the supporting member 32 is pulled, excessive wrenching force is not caused in the parts that support both the ends of the winding shaft 61 respectively.
When wrenching of the winding shaft 61 occurs, a rotational load on the winding shaft 61 increases when the user unwinds the supporting member 32. When the wrenching of the winding shaft 61 is large, the first case 66 inclines with respect to the winding shaft 61, thereby causing distortion in the rotation mechanism 62 (see
When wrenching of the winding shaft 61 occurs, a rotational load on the winding shaft 61 increases when the user winds the supporting member 32. When the wrenching is large, the first case 66 inclines with respect to the winding shaft 61, thereby causing distortion in the rotation mechanism 62 (see

In particular, for the support shaft holding member 87 holding the support shaft 86, angle adjustment in multiple stages is possible by a stopper function of the angle adjustment member 89 provided on the leg portion 80. However, when external force exceeding holding force of the stopper is applied, the support shaft holding member 87 comes off from the stopper that holds the support shaft holding member 87 at that time, and the position of the support shaft 86 is shifted or the support shaft 86 overturns. In the stacker unit 31 of the present exemplary embodiment, the pulling force acting on the supporting member 32 is mainly received by the leg portion 80 via the adjuster 43. Accordingly, the pulling force that the support shaft 86 receives from the supporting member 32 is suppressed to be small, and a direction of the pulling force faces is a nearly downward direction that is different from a rotation direction of the support shaft 86, thus position shift or overturning of the support shaft 86 is unlikely to occur.

For example, once ending use of the stacker unit 31, the user removes the attachment shaft 36 from the attachment portion 84, removes the supporting member 32 from the support shaft 86, and spreads the supporting member 32 and places on the floor surface. As illustrated in

As illustrated in
In the state illustrated in
After the end of use of the stacker unit 31, the user removes the adjuster 43, the attachment shaft 36, and the guide string 44 from the printer 11, and in the manner illustrated in
According to the exemplary embodiment described above, the following advantages are achieved.
(1) The stop mechanism 62b constituting the rotation mechanism 62 stops the winding shaft 61, in the first state in which the unwind amount is the first unwind amount, and in the second state in which the unwind amount is the second unwind amount that is greater than the first unwind amount. Thus, the unwinding length of the supporting member 32 is adjusted in accordance with the length of the medium 99, and additionally, the supporting member 32 can be maintained at the adjusted length. Thus, the supporting member 32 from a part fixed to the printer 11 to the winding shaft 61 can be held in a desired posture suitable for loading the medium 99 to be discharged. Additionally, the winding unit 60 is placed on a flat surface such as the floor surface 91. Thus, compared to the configuration described in JP-A-2017-65842, in which the winding shaft is supported by, for example, the pair of rotatable side rods, and the like, there is no concern about mutual position shift between the first case 66 and the second case 76. In a state in which the winding unit 60 is placed on a flat surface by the placement portion 57, for example, the first case 66 and the second case 76 are held so as to be non-rotatable with respect to each other in the plane orthogonal to the winding axis line 61a of the winding shaft 61. Accordingly, twisting of the winding shaft 61 is unlikely to occur. Additionally, for example, the first case 66 and the second case 76 are held so as to be non-rotatable with respect to each other in a state in which the axis lines 67a and 77a of the respective bearing portions 72b supporting the winding shaft 61 are aligned with each other. Accordingly, an angle formed by the first case 66 and the second case 76 is less likely to change, so wrenching of the winding shaft 61 is less likely to occur. Accordingly, an external load such as twisting or wrenching of the winding shaft 61 due to position shift of the respective parts supporting both ends of the winding shaft 61 can be suppressed.
(2) Each of the first case 66 and the second case 76 is fixed to the rigid coupling member 59 by two screws in the X-axis direction orthogonal to the winding axis line 61a of the winding shaft 61, thus the first case 66 and the second case 76 cannot rotate in the plane orthogonal to the winding axis line 61a of the winding shaft 61. That is, twisting of the winding shaft 61 does not occur. Further, with respect to the rigid coupling member 59, the first case 66 and the second case 76 are held so as to be non-rotatable with respect to each other, in a state in which the first main axis line 67a of the first main shaft 67 supporting the winding shaft 61, and the second main axis line 77a of the second main shaft 77 are aligned with the winding axis line 61a of the winding shaft 61, the angle formed by the first case 66 and the second case 76 does not change. In other words, wrenching of the winding shaft 61 does not occur. Accordingly, the user can move the first case 66 and the second case 76 simultaneously with a positional relationship unchanged. Thus, in addition to a case in which the winding unit is placed on a flat surface such as a floor surface, even during an operation of changing the winding amount of the supporting member 32, an external load such as twisting or wrenching of the winding shaft 61 due to position shift of the respective parts supporting both the end portions of the winding shaft 61 can be suppressed.
(3) In a state in which both the first installation surface 93 of the first case 66 and the second installation surface 94 of the second case 76 are in surface contact with the floor surface 91, the winding unit 60 is placed on a flat surface such as the floor surface 91. Accordingly, there is no rattling on the floor surface 91, an external load such as twisting or wrenching of the winding shaft 61 due to position shift of the respective parts supporting both ends of the winding shaft 61 can be suppressed.
(4) In a state in which both the first installation surface 93 of the first case 66 and the second installation surface 94 of the second case 76 are installed on the floor surface 91, each of the cases is fixed to the rigid coupling member 59 with the plurality of screws 58. Thus, in addition to a case in which the winding unit is placed on a flat surface such as a floor surface, when an operation of changing the unwind amount of the supporting member 32 is started, an external load such as twisting or wrenching of the winding shaft 61 due to position shift of the respective parts supporting both the end portions of the winding shaft 61 can be suppressed.
(5) The winding unit 60 includes the guide member 59g includes the straight portion 59a longer than the length of the supporting member 32 in the axial direction of the winding shaft 61, extending linearly in the axial direction of the winding shaft 61, and having a rectangular-shaped cross section orthogonal to the axial direction. Thus, when the user tries to bring the supporting member 32 into contact with the straight portion 59a, a fold extending in the width direction is formed at a site of the supporting member 32 contacting the straight portion 59a, thereby eliminating wrinkles in the supporting member 32. The user can wind the supporting member 32 around the winding shaft 61, for which the wrinkles are eliminated by the fold formed at the site contacting the straight portion 59a. In addition, since the coupling member 59 also serves as the guide member 59g, the number of components is kept low.
(6) The rotation mechanism 62 is provided inside the first case 66. Since the first case 66 covers the opposite side of the part to which the winding shaft 61 is mated in the first mating member 63 constituting the rotation mechanism 62, foreign matter cannot flow into the rotation mechanism 62. Thus, malfunction of the rotation mechanism 62 due to foreign matter can be prevented.
(7) The unwind amount regulating portion 70 is provided inside the second case 76. since the second case 76 covers the opposite side of the part to which the winding shaft 61 is mated in the second mating member 71 constituting the unwind amount regulating portion 70, foreign matter cannot flow into the winding amount restricting portion 70. Thus, malfunction of the unwind amount regulating portion 70 due to foreign matter can be prevented.
(8) Since the biasing force of the flat spiral spring 64 rotates the winding shaft 61 in the direction in which the supporting member 32 is wound, it is not necessary for the user itself to rotate the winding shaft 61 to change the unwind amount of the supporting member 32. An operation for changing the unwind amount of the supporting member 32 to be small can be facilitated. Also, when the use of the stacker unit 31 is ended, the supporting member 32 can be easily and rapidly wound around the winding shaft 61.
(9) Unless the operated portion 68b of the operation switch 68 is operated from the non-operating position protruding outward the outer surface of the first case 66 to the operating position located on the inner side of the first case 66 than the outer surface of the first case 66, the ratchet claw 65 does not disengage from the ratchet gear 63a, so the winding shaft 61 is not driven by the biasing force of the flat spiral spring 64. For example, when the operation switch 68 is pressed against the user's intent, for example, when a person's foot hits the operation switch 68, or when the winding unit 60 is accidentally overturned and the operation switch 68 is pressed, the stop mechanism 62b is not released, thus the winding mechanism 62a can be prevented from being driven. Additionally, when the user operates the operation switch 68 with the intention of winding the supporting member 32, the operated portion 68b of the operation switch 68 is operated from the non-operating position protruding outward the outer surface of the first case 66 to the operating position located on the inner side of the first case 66 than the outer surface of the first case 66. Accordingly, the ratchet claw 65 disengages from the ratchet gear 63a, and the winding shaft 61 is driven by the biasing force of the flat spiral spring 64.
(10) The leg portion 80 of the printer 11 includes the plurality of rollers 81a that contact a surface such as the floor surface 91 on which the printer 11 is installed and are rotatable, the locking lever 81b that regulates rotation of the roller 81a, and the placement surfaces 82 and 83 on which the winding unit 60 is placed. When the user adjusts the unwind amount of the supporting member 32, winds the supporting member 32 around the winding shaft 61, or moves the stacker unit 31, the printer 11 is pulled through the supporting member 32. However, by locking the roller 81a of the base 96, movement of the printer 11 can be prevented. Furthermore, after use of the stacker unit 31 is ended, by placing the stacker unit 31 on the first placement surface 82 and the second placement surface 83 provided on the base 96 of the leg portion 80, the stacker unit 31 can be compactly housed.
(11) When the winding unit 60 rotates in the direction in which the supporting member 32 is unwound, the rope 69 is gradually wound around the planetary pulley 75. When the planetary pulley 75 completely winds the rope 69, the user will not be able to unwind the supporting member 32 anymore, thus the user can be prevented from excessively unwinding the supporting member 32. For example, in a case in which the supporting member 32 is unwound, when the winding shaft 61 is excessively rotated in the unwinding direction W1, thus an end in the unwinding direction W1 of the supporting member 32 is exceeded, winding of the supporting member 32 is started in an opposite winding direction. In this case, an extra operation occurs such as reversing of the supporting member and slight winding. Compared to this, in the present exemplary embodiment, when the unwind amount exceeds a predetermined amount, the rotation of the winding shaft 61 in the unwinding direction W1 is regulated by the unwind amount regulating portion 70, thus the above-described inconvenience can be avoided.
(12) When the winding unit 60 rotates in the direction in which the supporting member 32 is wound, the rope 69 is gradually wound around the sun pulley 79. When the sun pulley 79 completely winds the rope 69, the user will not be able to wind the supporting member 32 anymore, thus the user can be prevented from excessively winding the supporting member 32. For example, in a case in which the supporting member 32 is wound, when the winding shaft 61 is rotated excessively in the winding direction W2, and in a case of a configuration in which the attachment shaft 36 is provided on a tip of the supporting member 32, or in case of a configuration in which the adjuster 43 and the guide string 44 are provided near the tip of the supporting member 32, there is a concern that these components collide with or are caught in constituent elements of the stacker unit 31 when the supporting member 32 is wound. Compared to this, in the present exemplary embodiment, when the unwind amount is smaller than a predetermined amount, the rotation of the winding shaft 61 in the winding direction W2 is regulated by the unwind amount regulating portion 70, thus the above-described inconvenience can be avoided.
(13) The printer 11 includes the support shaft 86 on which the supporting member 32 is hung, and that supports the supporting member that is hung, and the pair of support shaft holding members 87 that hold both the ends of the support shaft 86 respectively, and are rotatably attached to the base 96 of the leg portion 80 of the printer 11. In the direction in which the printer 11 discharges the medium 99 after printing, the winding unit 60 is placed at the position on the floor surface 91 facing the position where the part of the supporting member 32 is fixed to the printer 11, with the support shaft 86 interposed therebetween. A part of tip of the supporting member 32 unwound from the winding unit 60 is fixed to a position lower than the support shaft 86 in the printer 11, in a state in which the supporting member 32 is hung on the support shaft 86 positioned higher than the winding unit 60. By setting the support shaft holding member 87 to a desired angle to change the position of the support shaft 86, the posture of the supporting member 32 loading the medium 99 is changed.
When the supporting member 32 is attached to the printer 11 in the forward discharge posture in which the medium 99 is discharged forward the discharge port 13, the user increases the unwind amount of the support member 32, moves the position of the support shaft 86 rearward the medium transporting surface of the discharge guide 27, and installs the winding unit 60 at a position far from the printer 11. The medium 99 is loaded on the supporting member 32 in a posture in which a printed surface faces upward. On the other hand, when the supporting member 32 is attached to the printer 11 in the rearward discharge posture in which the medium 99 is discharged rearward the discharge port 13, the user decreases the unwind amount of the support member 32, moves the position of the support shaft 86 forward the medium transporting surface of the discharge guide 27, and installs the winding unit 60 at a position close to the printer 11. The medium 99 is loaded on the supporting member 32 in a posture in which a printed surface faces downward. The user can switch the supporting member 32 between the forward discharge posture and the rearward discharge posture, by the aforementioned easy operation.
(14) The winding type stacker unit 31 that is an example of a loading apparatus, includes the sheet-like supporting member 32 that is fixed in part to the printer 11 and is used, and capable of supporting the medium 99 discharged from the discharge port 13 of the printer 11, and the winding unit 60 capable of winding the supporting member 32. The winding unit 60 includes the winding shaft 61 to which the one end of the supporting member 32 is attached, the rotation mechanism 62, the first case 66 and the second case 76 that rotatably support both the end portions of the winding shaft 61 respectively, and the placement portion 57 that places the winding unit 60 on a flat surface. The rotation mechanism 62 includes the winding mechanism 62a for rotating the winding shaft 61 in the direction in which the supporting member 32 is wound, and the stop mechanism 62b that can stop the winding shaft 61 in the first state in which the length of the supporting member 32 unwound from the winding unit 60 is the first unwind amount, and in the second state in which the length of the supporting member unwound from the winding shaft is the second unwind amount greater than the first unwind amount. The first case 66 is positioned on one side outer than the supporting member 32, in the axial direction of the winding shaft 61, and rotatably supports the winding shaft 61. The second case 76 is positioned on another side outer than the supporting member 32, in the axial direction, and rotatably supports the winding shaft 61. By attaching the stacker unit 31 to the printer 11, identical effects to that of the medium processing apparatus 10 can be obtained.
(15) The medium loading method is a method for using the stacker unit 31 including the winding unit 60 and the supporting member 32 in the medium processing apparatus 10, to load the medium 99 subjected to printing processing and discharged from the discharge port 13 of the printer 11. The printer 11 includes the support shaft 86 on which the supporting member 32 is hung, and that supports the supporting member that is hung, and the pair of support shaft holding members 87 that hold both the ends of the support shaft 86 respectively, and are rotatably attached to the printer 11. A part of the supporting member 32 unwound from the winding unit 60 is fixed to the printer 11, and in the direction in which the printer 11 discharges the medium 99 after printing, the winding unit 60 is placed at the position facing the position where the part of the supporting member 32 is fixed to the printer 11, with the support shaft 86 interposed therebetween. The supporting member 32 unwound from the winding unit 60 is brought into a state of being hung on the support shaft 86 positioned higher than the winding unit 60. By adjusting the support shaft holding member 87 to a desired angle to change the position of the support shaft 86, the posture of the supporting member 32 loading the medium 99 is changed. By changing the position of the support shaft 86, the posture of the support member 32 can be switched between the forward discharge posture in which the medium 99 discharged from the discharge port 13 is discharged forward and is loaded on the supporting member 32, and the rearward discharge posture in which the medium 99 discharged from the discharge port 13 is discharged rearward and is loaded on the supporting member 32.
Note that, the above-described exemplary embodiment may be modified to an embodiment such as the following modified examples. Furthermore, an appropriate combination of the above-described exemplary embodiment and modification examples described below can be regarded as a further modification example, or an appropriate combination of the following modified examples can be regarded as a further modification example.
In the present exemplary embodiment, the rope 69 is wound by the planetary movement of the planetary pulley 75, by rotating the disk member 72, in the state in which the sun gear 78 and the sun pulley 79 fixed to the second main shaft 77 are fixed to the second case 76. As illustrated in
The unwind amount regulating portion 70 may be another mechanism. For example, as illustrated in
There may be a plurality of the coupling members 59 that fix the first case 66 and the second case 76 to each other. The coupling members 59 may be provided on both a front and a rear in a direction along the Y-axis with respect to the winding shaft 61. According to this configuration, compared to the configuration of the above-described exemplary embodiment, since twisting or wrenching of the winding shaft 61 does not occur, required strength for the coupling member 59 is suppressed to be small.
The method of fixing the first case 66 and the second case 76 to the coupling member 59 is not limited to fastening by screws. Other fixing methods such as mating may be used, or the first case 66, the second case 76, and the coupling member 59 may be integrally formed as one component. It is sufficient that fixing can be made so that twisting or wrenching does not occur between the first case 66 and the second case 76.
The coupling member 59 and guide member 59g may be configured with respective separate members. In this case, the guide member 59g may be attached or affixed to a surface of the coupling member 59. Furthermore, a component formed integrally with the first case 66, the second case 76, and the coupling member 59 may have the straight portion 59a, or the guide member 59g may be attached or affixed to the component.
In the exemplary embodiment described above, the user brings the surface (back surface) on the side of the floor of the supporting member 32 in contact with the straight portion 59a of the guide member 59g as an example of the coupling member, but may also bring a surface (front surface) opposite to the side of the floor of the supporting member 32 into contact with the straight portion 59a. For example, the winding direction of the supporting member 32 with respect to the winding shaft 61 is reversed from that of the above-described exemplary embodiment, and the guide member 59g is disposed above along the Z-axis with respect to the winding shaft 61, and the surface (front surface) opposite to the side of the floor of the supporting member 32 is brought into contact with the straight portion 59a.
In the above-described exemplary embodiment, the user slightly inclines the winding unit 60 with respect to the floor, and brings the back surface of the supporting member 32 in contact with the straight portion 59a of the guide member 59g, but a configuration may be adopted in which the supporting member 32 constantly contacts the straight portion 59a, with the winding unit 60 placed on the floor.
The guide member 59g may be above the winding shaft 61, with the winding unit 60 placed. When winding the supporting member 32 around the winding shaft 61, the user inverts the winding unit 60 vertically to bring the front surface of the supporting member 32 into contact with the straight portion 59a.
The radius of curvature of the corner portion of the straight portion 59a is not limited to the range of 2 to 8 mm. However, when the radius of curvature is too large, a function as a guide during winding deteriorates. When the radius of curvature is too small, the front surface of the supporting member 32 is loaded when being wound, and the front surface of the supporting member 32 is easily damaged. For example, the radius of curvature may be a predetermined value within a range of 1 mm to 15 mm. Note that, the roundness of the corner portion of the straight portion 59a may be removed.
A part of the supporting member 32 that is fixed to the printer 11 may be fixed to the housing 12. For example, in the supporting member 32 provided with the attachment shaft 36 on the tip thereof, a part of the supporting member 32 is fixed to the housing 12, by fixing the attachment shaft 36 to the housing 12 of the printer 11. Additionally, there may be a plurality of fixing locations. As a fixing destination of a part of the supporting member 32, the user may select the housing 12 or the leg portion 80, to attach the part of the supporting member 32 to the selected one. Also, when the leg portion 80 is selected as the fixing destination of the part of the supporting member 32, the part may be attached to the base 96 of the leg portion 80, or to the stand 95 of the leg portion 80.
For the supporting member 32, in place of the attachment shaft 36, a panel provided with a plurality of mounting holes is fixed, and the mounting hole may be hooked on the housing 12, or a mounting hole may be provided in the supporting member 32 itself, and the mounting hole may be hooked on the housing 12.
The placement portion 57 is not limited to a configuration including the bottom of the first case 66 and the bottom of the second case 76. For example, the first case 66 and the second case 76 may be fixed to an upper surface of the coupling member 59, and a bottom of the coupling member 59 may be the placement portion 57. Further, another member may be fixed to the coupling member 59, and a bottom of the member may be the placement portion 57.
Each of the first installation surface 93 that is a bottom of a part corresponding to the first case 66 in the winding unit 60, and the second installation surface 94 that is a bottom of a part corresponding to the second case 76, is not limited to a flat surface, and may be a surface constituted by a plurality of convex portions. For example, each of the first installation surface 93 and the second installation surface 94 may be a surface having a plurality of, three or more, convex portions. In this case, three or more convex portions of the first installation surface 93 and three or more convex portions of the second installation surface 94 contact an identical flat surface.
The first installation surface and the second installation surface are not limited to the respective bottoms of the first case 66 and the second case 76. The first case 66 and the second case 76 may be fixed to the upper surface of the coupling member 59, and a bottom of a part corresponding to the first case 66 of the coupling member 59 may also be the first installation surface, and a bottom of a part corresponding to the second case 76 may also be the second installation surface. Further, other members may be fixed to the cases 66 and 76, respectively, and bottoms of the respective members may also be the first installation surface and the second installation surface, respectively.
The rotation mechanism 62 may also be provided inside the second case 76, or may also be provided inside both the first case 66 and the second case 76. When a rotating biasing portion such as the flat spiral spring 64, and the stop mechanism 62b that regulates rotation of the winding shaft 61 by the rotary biasing portion are provided inside an identical case, a possibility that the winding shaft 61 twists is reduced. When the rotation mechanism 62 is provided inside the second case 76, the second case 76 is also provided with the operation switch 68 that releases the stop mechanism 62b.
A configuration may also be adopted in which the operated portion 68b is provided on the ratchet claw 65, and the stop mechanism 62b is released, when the operated portion 68b is operated from the non-operating position protruding outward the outer surface of the first case 66, to the operating position located on the inner side of the case than the outer surface. In this case, a dedicated component is not required for the operation switch 68.
The rotary biasing portion is not limited to the flat spiral spring 64. For example, a torsion spring having a large winding number, or a torsion spring that can be twisted multiple times may be used.
The drive unit for driving the winding shaft 61 to rotate may also be a motor. In addition to the operation switch 68 that rotates the winding shaft 61 in the winding direction W2, an operation switch that rotates the winding shaft 61 in the unwinding direction W1 may be provided, and rotation in either direction of the winding shaft 61 may also be driven by a motor.
The winding mechanism 62a that configures the rotation mechanism 62 may have a configuration that does not include a drive unit such as the flat spiral spring 64 or a motor. The winding mechanism 62a may be configured such that winding and unwinding of the supporting member 32 are performed by manual rotation by the user.
In the ratchet gear 63a, a tooth may be absent every other tooth, or may be absent at a certain cycle. For example, when a tooth is absent every other tooth, a minimum unit of unwinding length is doubled. When there is only one tooth on a circumference, the minimum unit of unwinding length is a circumferential length corresponding to one circumference of the winding shaft.
The stop mechanism 62b may be a one-way clutch instead of a ratchet mechanism.
A configuration may be adopted in which, as in a case of a roll curtain attached to a window of a house or a vehicle, after the supporting member 32 is slightly unwound by the user, and when tension of the supporting member 32 is slightly loosened, the supporting member 32 is automatically wound. In this case, the operation switch 68 is not required.
The placement surfaces 82 and 83 on which the winding unit 60 is placed may be provided on the stand 95 of the leg portion 80, or may be provided on the housing 12.
When displaying an installation method of the stacker unit 31, in order for the user to lock the roller 81a of the printer 11 to prevent the printer 11 from moving, a screen of caution may be displayed on a display screen of a display device provided on the printer 11.
The rope 69 may be metal such as stainless steel, or may be a synthetic resin such as polyester or nylon. The rope 69 may be formed by intertwining many ultrafine wires together, or may be subjected to a coating process of a synthetic resin for durability and corrosion resistance.
The unwind amount regulating portion 70 may be provided inside the first case 66. Both the rotation mechanism 62 and the unwind amount regulating portion 70 may be provided inside the first case 66.
In the present exemplary embodiment, the sun gear 78 and the planetary gear 74 are identical in the number of teeth, but the present disclosure is not limited thereto. For example, in a case in which a ratio of the number of teeth of the sun gear 78 to the number of teeth of the planet gears 74 is 2:1, when the disk member 72 rotates once in a clockwise direction, the planetary gear 74 rotates twice in the clockwise direction. In this case, by setting a ratio of a pulley diameter of the sun pulley 79 to a pulley diameter of the planetary pulley 75 to 2:1, an unwinding length of the rope 69 of the sun pulley 79 and a winding length of the rope 69 of the planetary pulley 75 are equalized. That is, it is sufficient that the ratio of the number of teeth of the sun gear 78 to the number of teeth of the planetary gear 74, and the ratio of the pulley diameter of the sun pulley 79 to the pulley diameter of the planetary pulley 75 are set to be identical. The number of teeth of each of the sun gear 78 and the planetary gear 74 can be set as appropriate.
The rope 69 may be wound in an opposite direction. However, when the sun pulley 79 unwinds the rope 69, the planetary pulley 75 winds the rope 69, and when the sun pulley 79 winds the rope 69, the planetary pulley 75 unwinds the rope 69.
A configuration may be adopted in which a ring gear that intermeshes with the planetary gear 74 is provided on an inner surface of an outer circumference of the second mating member 71 instead of the sun gear 78, and the planetary gear 74 is moved as a planet by rotating the ring gear, and the sun pulley 79 unwinds the rope 69, and the planetary pulley 75 winds the rope 69.
Depending on users, a length of the rope 69 may be changed. A required unwinding length of the supporting member 32 differs for a user using a medium having a large length in the transport direction, and a user using only a medium having a small length in the transport direction. When the length of the rope 69 is decreased for the user using only the medium having the small length in the transport direction, excessive unwinding of the supporting member 32 by the user can be prevented.
Hereinafter, technical concepts and effects thereof that are understood from the above-described exemplary embodiments and modified examples will be described.
(A) A medium processing apparatus includes, a printer provided with a discharge unit for discharging a processed medium, a supporting member having a sheet-like shape and fixed, in part, to the printer, and moreover configured to support the medium discharged from the discharge unit, and a winding unit configured to wind the supporting member and move with respect to the printer, wherein the winding unit includes a winding shaft to which one end of the supporting member is attached, a rotation mechanism including a winding mechanism for rotating the winding shaft in a direction of winding the supporting member and a stop mechanism configured to stop the winding shaft, in a first state in which a length of the supporting member unwound from the winding shaft is a first unwind amount, and in a second state in which a length of the supporting member unwound from the winding shaft is a second unwind amount that is greater than the first unwind amount, a first case positioned at one outer side of the supporting member in an axial direction of the winding shaft and rotatably supporting the winding shaft, a second case positioned at another outer side of the supporting member in the axial direction and rotatably supporting the winding shaft, and a placement portion that, when the winding unit is placed on a flat surface, contacts the flat surface.
According to this configuration, the winding shaft can be stopped, in the first state in which the unwind amount is the first unwind amount, and in the second state in which the unwind amount is the second unwind amount that is greater than the first unwind amount. An unwinding length of the supporting member is adjusted in accordance with a length of the medium, and additionally, the supporting member can be maintained at an adjusted length. Thus, the supporting member from a part fixed to the printer to the winding shaft can be held in a desired posture suitable for supporting the medium to be discharged. Additionally, the winding unit is placed on a flat surface such as a floor surface. Thus, compared to a configuration in which the winding shaft is supported by, for example, a pair of rotatable side rods, and the like, there is no concern about mutual position shift between the first case and the second case. In a state in which the winding unit is placed on a flat surface by the placement portion, for example, the first case and the second case are held so as to be non-rotatable with respect to each other in a plane orthogonal to an axis line of the winding shaft. Accordingly, twisting of the winding shaft is unlikely to occur. Additionally, for example, the first case and the second case are held so as to be non-rotatable with respect to each other in a state in which axis lines of the respective bearing portions supporting the winding shaft are aligned with each other. Accordingly, an angle formed by the first case and the second case is less likely to change, so wrenching of the winding shaft is less likely to occur. Accordingly, an external load such as twisting or wrenching of the winding shaft due to position shift of respective parts supporting both ends of the winding shaft can be suppressed.
(B) In the above-described medium processing apparatus, the placement portion may include a first installation surface including a bottom of the first case, and a second installation surface including a bottom of the second case, and when the first installation surface contacts a flat surface, the second installation surface may contact the flat surface.
According to this configuration, the first case and the second case are, in a state in which both the first installation surface and the second installation surface contact a flat surface such as a floor surface, placed on the flat surface. In a state in which the winding unit is placed, the first case and the second case are placed on a flat surface such as a floor surface without rattling, thus are held in a state of being non-rotatable with respect to each other. Thus, an external load such as twisting or wrenching of the winding shaft due to position shift of the respective parts supporting both ends of the winding shaft can be suppressed.
(C) The above-described medium processing apparatus may include a coupling member configured to fix the first case and the second case to be non-rotatable with respect to each other in the plane orthogonal to the axis line of the winding shaft.
According to this configuration, the first case and the second case are fixed to each other via the coupling member, thus are held so as to be non-rotatable with respect to each other in the plane orthogonal to the axis line of the winding shaft. Thus, in addition to a case in which the winding unit is placed on a flat surface such as a floor surface, even when an operation of changing an unwind amount of the supporting member is started, an external load such as twisting or wrenching of the winding shaft due to position shift of the respective parts supporting both the end portions of the winding shaft can be suppressed.
(D) In the above-described medium processing apparatus, a configuration may be adopted in which, the winding unit includes a guide member having a straight portion that guides the supporting member contacting therewith, and the straight portion has a length longer than the length of the supporting member in the axial direction of the winding shaft, extends along the axial direction, and has a cross section that has a is a convex shape orthogonal to the axial direction.
According to this configuration, when a user tries to, by the straight portion in the winding unit that serves as a guide when the supporting member is wound, bring the supporting member into contact with the straight portion of the guide member, a fold extending in a width direction is formed at a site of the supporting member contacting the straight portion, thereby eliminating wrinkles in the supporting member. The user can wind the supporting member around the winding shaft, for which the wrinkles are eliminated by the fold formed at the site contacting the straight portion.
(E) In the above-described medium processing apparatus, the rotation mechanism may also be provided inside at least one of the first case and the second case.
According to this configuration, malfunction of the rotation mechanism due to inflow of foreign matter can be prevented.
(F) In the above-described medium processing apparatus, the winding mechanism may include a drive unit for driving the winding shaft to rotate.
According to this configuration, since the drive unit rotates the winding shaft, it is not necessary for the user itself to rotate the winding shaft to change the unwind amount of the supporting member. The operation for changing the unwind amount of the supporting member can be facilitated.
(G) In the above-described medium processing apparatus, the drive unit may be a rotary biasing portion for biasing the winding shaft in a winding direction.
According to this configuration, since the rotary biasing portion rotates the winding shaft in the winding direction in which the supporting member is wound, it is not necessary for the user itself to rotate the winding shaft to reduce the unwind amount of the supporting member. Thus, an operation of reducing the unwind amount of the supporting member can be facilitated.
(H) In the above-described medium processing apparatus, a configuration may be adopted in which, in one of the first case and the second case that is provided with the rotation mechanism, an operation switch is provided that releases stop of the winding shaft by the stop mechanism, and rotates the winding shaft by the drive unit, and the operation switch includes a operated portion that is operated by the user, and the step by the stop mechanism is released when the operated portion is operated from a non-operating position, where the operated portion protrudes outward of an outer surface of the case, to an operating position located further inside of the case than the outer surface.
According to this configuration, unless the operated portion is operated from the non-operating position protruding outward the outer surface of the case, to the operating position located on the inner side of the case than the outer surface, the winding shaft is not driven. In other words, when the operated portion is pressed by an erroneous operation, the drive unit does not drive the rotation mechanism. For example, the drive unit can be prevented from driving the rotation mechanism, by unintentional operations, such as a person's foot hitting the operation switch, accidental overturning of the winding unit to press the operation switch, and the like. Additionally, when the operated portion is operated from the non-operating position protruding outward the outer surface of the case, to the operating position located on the inner side of the case than the outer surface, the stop mechanism is released, and the winding shaft is driven. That is, when the operated portion is pushed down by an operation of the user, the drive unit can drive the winding mechanism.
(I) In the above-described medium processing apparatus, the printer may include a leg portion, and the leg portion may include: a plurality of rollers contacting a surface, at which the printer is installed and configured to rotate; a locking member regulating rotation of the roller; and a placement surface at which the winding unit is placed.
According to this configuration, in a case in which the user unwinds or winds the supporting member, or moves the winding unit, even when the printer is pulled via the supporting member, movement of the printer can be prevented by locking the roller of the leg portion.
(J) In the above-described medium processing apparatus, the winding unit may include an unwind amount regulating portion regulating an unwind amount of the supporting member, and the unwind amount regulating portion may regulate rotation of the winding shaft in the unwinding direction, when the unwind amount exceeds a predetermined amount. According to this configuration, the unwind amount of the supporting member can be regulated so as not to exceed the predetermined amount, thus it is possible to prevent the user from excessively unwinding the supporting member.
(K) In the above-described medium processing apparatus, the winding unit may include an unwind amount regulating portion regulating an unwind amount of the supporting member, and the unwind amount regulating portion may regulate rotation of the winding shaft in the winding direction, when the unwind amount is smaller than a predetermined amount. According to this configuration, the unwind amount of the supporting member can be regulated so as to be a length equal or smaller than the predetermined amount, thus it is possible to prevent the user from excessively winding the supporting member.
(L) In the above-described medium processing apparatus, the unwind amount regulating portion may also be provided inside at least one of the first case and the second case. According to this configuration, malfunction of the unwind amount regulating portion due to inflow of foreign matter can be prevented.
(M) In the medium processing apparatus, the printer includes a support shaft at which the supporting member is hung and which supports the supporting member that is hung, and a pair of support shaft holding members that hold both ends of the support shaft respectively and are rotatably attached to the printer, the supporting member unwound from the winding unit that is located in such a way that the support shaft interposed between the winding unit and a position, where the part of the supporting member is fixed to the printer in a direction in which the printer discharges the medium after printing, is fixed to a position lower than the support shaft in the printer, in a state of being hung at the support shaft that is positioned higher than the winding unit, and an angle of the support shaft holding member is adjusted and hence a posture of the supporting member loading the medium may be changed, thereby changing a posture of the support member onto which the medium is loaded shaft.
According to this configuration, the user can switch the supporting member between a forward discharge posture and a rearward discharge posture, by an easy operation for changing the position of the support shaft. When discharging the medium forward the discharge unit, the user increases the unwind amount of the supporting member, moves the position of the support shaft rearward the discharge unit, and installs the winding unit at a position far from the printer. The medium is loaded on the supporting member in a posture in which a printed surface after printing faces upward. When discharging the medium rearward the discharge unit, the user decreases the unwind amount of the supporting member, moves the position of the support shaft forward the discharge unit, and installs the winding unit at a position close to the printer. The medium is loaded on the supporting member in a posture in which a printed surface after printing faces downward.
(N) A loading apparatus is a loading apparatus that includes, a supporting member having a sheet-like shape and fixed, in part, to a printer and moreover configured to support a medium discharged from a discharge unit of the printer, and a winding unit configured to wind the supporting member, wherein the winding unit includes a winding shaft to which one end of the supporting member is attached, a rotation mechanism including a winding mechanism rotating the winding shaft in a direction of winding the supporting member and a stop mechanism configured to stop the winding shaft, in a first state in which a length of the supporting member unwound from the winding shaft is a first unwind amount, and in a second state in which a length is a second unwind amount that is greater than the first unwind amount, a first case positioned at one outer side of the supporting member in an axial direction of the winding shaft and rotatably supporting the winding shaft, a second case positioned at another outer side of the supporting member in the axial direction and rotatably supporting the winding shaft, and a placement portion that, when the winding unit is placed at a flat surface, contacts the flat surface. According to this configuration, by attaching the loading apparatus to the printer, similar effects to those of the above-described medium processing apparatus can be obtained.
(O) A media loading method is a medium loading method for loading a processed medium discharged from a discharge unit of a printer with use of a loading apparatus including the winding unit and the supporting member in a medium processing apparatus, wherein the printer includes a support shaft at which the supporting member is hung and which supports the supporting member that is hung, and a pair of support shaft holding members that hold both ends of the support shaft respectively and are rotatably attached to the printer, the method including fixing a part of the supporting member unwound from the winding unit to the printer, and, in a direction in which the printer discharges the medium after printing, placing the winding unit in such a way that the support shaft is interposed between the winding unit and a position, where the part of the supporting member is fixed to the printer, so as to bring the supporting member unwound from the winding unit into a state of being hung at the support shaft that is positioned higher than the winding unit, and adjusting an angle of the support shaft holding member to change a position of the support shaft, thereby changing a posture of the supporting member at which the medium is loaded.
According to this method, the user can switch the supporting member between the forward discharge posture and the rearward discharge posture, by an easy operation for changing the position of the support shaft. When discharging the medium forward the discharge unit, the user increases the unwind amount of the supporting member, moves the position of the support shaft rearward the discharge unit, and installs the winding unit at a position far from the printer. The medium is loaded on the supporting member in a posture in which a printed surface after printing faces upward. When discharging the medium rearward the discharge unit, the user decreases the unwind amount of the supporting member, moves the position of the support shaft forward the discharge unit, and installs the winding unit at a position close to the printer. The medium is loaded on the supporting member in a posture in which a printed surface after printing faces downward.
