  By the way, a clamp member can be used also when cut | disconnecting a medium. For example, the media may be cut across the width in order to separate the printed portion of the media from the unprinted portion. The clamp member can also be used in such a case. Here, when the medium is cut in the entire width direction, the cutter is moved from one end to the other end in the width direction of the medium. The clamp member disclosed in Patent Document 1 is provided along the conveyance direction of the medium, and is disposed closer to the center than both ends of the medium. Therefore, when the cutter moves from one end to the other end in the width direction of the medium, the cutter and the clamp member interfere with each other. When the medium is cut in the entire width direction, it is necessary to remove the clamp member when the cutter moves in the vicinity of the clamp member in order to avoid the interference. For this reason, when the clamp member is used, the cutting operation of the media becomes complicated, and the time required for the cutting operation becomes long.

  An object of the present invention is to provide a clamp member and a media cutting device that can prevent the media from lifting and can easily and quickly perform the cutting operation of the media.

  A clamp member according to the present invention includes a first upper surface portion, a second upper surface portion, and a groove formed between the first upper surface portion and the second upper surface portion and extending in a first direction. And a clamp member that presses the media placed on the first upper surface portion and the second upper surface portion against the first upper surface portion and the second upper surface portion. The clamp member includes a base housed in the groove of the table, a first rising part rising from the base part, and a first extending from the first rising part along the first upper surface part of the table. And a first member having an extending portion. The clamp member includes a second rising portion that rises from the base portion, and a second extending portion that extends from the second rising portion along the second upper surface portion of the tail portion. A member is provided. Further, the clamp member extends from the first extension portion along the first upper surface portion in the first direction, and urges the medium toward the first upper surface portion; and A second clamp portion extending in the first direction along the second upper surface portion from the second extension portion, and urging the media toward the second upper surface portion. A gap positioned above the groove of the table is formed between the first clamp part and the second clamp part.

  The media cutting device according to the present invention includes the clamp member.

  In the clamp member, since the first clamp portion and the second clamp portion press the media against the first upper surface portion and the second upper surface portion of the table, it is possible to prevent the media from being lifted. Further, a gap located above the table groove is formed between the first clamp part and the second clamp part. Therefore, a cutter can be passed between the first clamp part and the second clamp part. Therefore, according to the clamp member, the medium can be cut along the groove while the medium is pressed against the table. Since the cutter and the clamp member do not interfere with each other, it is not necessary to remove the clamp member. Therefore, the media can be cut easily and quickly.

  According to the present invention, it is possible to provide a clamp member and a media cutting device capable of preventing the media from lifting and performing the media cutting operation easily and quickly.

[Configuration of printer and media cutting device]
Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a printer / medium cutting apparatus 10 (hereinafter simply referred to as “printer apparatus 10”) that can print on the medium Me and cut the medium Me. The printer device 10 is an example of a media cutting device in that the media Me can be cut.

  In the following description, when the printer device 10 is viewed from the front as shown in FIG. 1, the direction away from the printer device 10 is defined as the front, and the direction approaching the printer device 10 is defined as the rear. As will be described later, when printing is performed on the medium Me, the medium Me on the table 20 is conveyed forward. Before and after in the following description corresponds to before and after based on the transport direction of the media Me. That is, the downstream side in the transport direction corresponds to the front side, and the upstream side in the transport direction corresponds to the rear side. The symbol Fr in the figure indicates the front and Rr indicates the rear. Further, the symbol Le indicates left, Ri indicates right, Up indicates upper, and Dn indicates lower.

  The printer device 10 includes a table 20 that supports the medium Me so as to be transportable, a carriage 12 on which a print head 12A (see FIG. 2) that performs printing on the medium Me is mounted, and a cutter mechanism 13 that can cut the medium Me. And left and right clamp members 30 that clamp (i.e., press) the left and right ends of the medium Me to the table 20. The printer device 10 also includes a feed roller 61 (see FIG. 4) that moves the medium Me back and forth, and a pinch roller 62 that sandwiches the medium Me together with the feed roller 61.

  The printer device 10 can transport the medium Me in the front-rear direction by the feed roller 61. The carriage 12 can move in the left-right direction. The cutter mechanism 13 is connected to the carriage 12 and can move in the left-right direction together with the carriage 12. Printing can be performed on the medium Me by ejecting ink from the print head 12A while moving the carriage 12 to the left and right with respect to the medium Me that is sequentially conveyed back and forth. On the other hand, when cutting the medium Me, the medium Me is transported to a predetermined position, and the cutter mechanism 13 is moved to the left and right in a state where the left and right ends of the medium Me are clamped by the clamp member 30.

  As shown in FIG. 2, the carriage 12 is movably supported by a guide rail 15 extending left and right. Although not shown, the carriage 12 is connected to a belt wound around a driving pulley and a driven pulley. The drive pulley is connected to a carriage drive motor 81 (see FIG. 10) described later. When the drive pulley is driven by the carriage drive motor 81, the belt travels, and the carriage 12 moves left and right on the guide rail 15. A plurality of print heads 12 </ b> A are mounted on the carriage 12. The number of print heads 12A mounted on the carriage 12 is not particularly limited. Here, the carriage 12 houses a plurality of print heads 12A that eject inks of different colors.

  The cutter mechanism 13 is configured to be movable to the left and right along the guide rail 15 together with the carriage 12. The cutter mechanism 13 is movably supported by the guide rail 15. The cutter mechanism 13 may be indirectly supported by the guide rail 15 via the carriage 12 or may be directly supported by the guide rail 15. The cutter mechanism 13 has a blade (cutter) 13a capable of cutting the media Me. The blade 13a is provided so as to be swingable in the vertical direction. When the blade 13a is rotated upward, the blade 13a can be positioned at a retracted position separated from the medium Me, and when the blade 13a is rotated downward, the blade 13a can be positioned at a contact position that contacts the medium Me. When cutting the medium Me, the blade 13a is rotated to the contact position, and the cutter mechanism 13 is moved in the left-right direction.

  The medium Me is, for example, a roll medium wound in a roll shape. The material of the medium Me may be paper such as plain paper, resin such as polyvinyl chloride or polyester, or metal such as aluminum or iron. The media Me can be composed of various materials. The medium Me is conveyed from the rear to the front by the feed roller 61 during printing.

  As shown in FIG. 3, the upper surface portion 21 of the table 20 is formed in a planar shape extending in the front, rear, left, and right directions, and the medium Me moves on the upper surface portion 21. A groove 22 is formed in a part of the upper surface portion 21 in the left-right direction. That is, the groove 22 extends in a direction orthogonal to the transport direction of the medium Me. If the direction in which the groove 22 extends is the first direction and the direction in which the medium Me is conveyed on the table 20 is the second direction, the first direction and the second direction are orthogonal to each other. The upper surface part 21 includes a first upper surface part 21 </ b> A located behind the groove 22 and a second upper surface part 21 </ b> B located in front of the groove 22. In other words, the groove 22 is formed between the first upper surface portion 21A and the second upper surface portion 21B. At least the second upper surface portion 21B is formed with a suction hole 21h for sucking the medium Me downward. The number and arrangement of the suction holes 21h are not particularly limited, but here, a plurality of suction holes 21h are arranged in the left-right direction to form a suction hole row. Two suction hole rows are provided in the front and rear.

  As shown in FIG. 9, a fan 83, which is an example of a suction device, communicates with the suction hole 21h. The fan 83 is configured to suck air from above toward the suction hole 21h. The fan 83 is configured to attract the medium Me to at least the second upper surface portion 21B. Note that the suction hole 21h communicating with the fan 83 may also be formed in the first upper surface portion 21A. In this case, the fan 83 attracts the medium Me to the first upper surface portion 21A and the second upper surface portion 21B.

  As shown in FIG. 4, the groove 22 is formed in a substantially T shape that is inverted up and down. The groove 22 has a bottom surface portion 22a extending in the left-right direction (front and back direction in FIG. 4), a side wall portion 22C positioned on the front side of the bottom surface portion 22a, and a side wall portion 22B positioned on the rear side of the bottom surface portion 22a. . The front side wall portion 22C and the rear side wall portion 22B intersect the bottom surface portion 22a. The front side wall 22C and the rear side wall 22B are separated from each other in the front-rear direction. The rear side wall portion 22B includes an accommodation wall portion 22Bb that intersects with the bottom surface portion 22a, and a retaining wall portion 22Bd that is positioned above the accommodation wall portion 22Bb. Similarly, the front side wall portion 22C includes an accommodation wall portion 22Cb that intersects the bottom surface portion 22a, and a retaining wall portion 22Cd that is positioned above the accommodation wall portion 22Cb. The housing wall portion 22Bb and the housing wall portion 22Cb face each other in the front-rear direction, and the retaining wall portion 22Bd and the retaining wall portion 22Cd face each other in the front-rear direction.

  The rear retaining wall portion 22Bd protrudes forward from the housing wall portion 22Bb. A stopper wall 22Bc extending forward is formed between the retaining wall portion 22Bd and the housing wall portion 22Bb. The front retaining wall 22Cd on the front side protrudes rearward from the housing wall 22Cb. A stopper wall 22Cc extending rearward is formed between the retaining wall portion 22Cd and the housing wall portion 22Cb.

  The upper part of the front retaining wall 22Cd on the front side is inclined so as to go forward as it goes upward. That is, it is formed in a tapered shape. The rear retaining wall portion 22Bd extends vertically. However, these shapes are only examples. Similarly to the rear retaining wall portion 22Bd, the front retaining wall portion 22Cd may be a surface extending vertically. Similarly to the front retaining wall portion 22Cd, the upper portion of the rear retaining wall portion 22Bd may be inclined to the rear as it goes upward. That is, it may be formed in a tapered shape.

[Configuration of clamp member]

The front end portion 35a serves as a guide for guiding the medium Me conveyed toward the rear to the lower side of the second clamp portion 35. In addition, the front-end | tip part 35a inclined with respect to the 2nd upper surface part 21B may be formed not only in the front side part of the 2nd clamp part 35 but in the left side part.

  Although illustration is omitted, the cutter mechanism 13 (see FIG. 2) may include a roller for pressing the media Me. When the cutter mechanism 13 moves left and right, the roller presses the medium Me against the table 20 while rolling on the medium Me. The first clamp part 34 and the second clamp part 35 may be configured to be pressed against the roller. By performing the cutting operation while pressing the first clamp part 34 and the second clamp part 35 with the roller, the blade 13a can be applied to the medium Me in a state where the floating of the medium Me is eliminated, and the cutting accuracy is improved. To do.

  As shown in FIG. 3, the first spacer 36 and the second spacer 37 are rectangular resin plates. However, the shapes and dimensions of the first spacer 36 and the second spacer 37 are not particularly limited. The first spacer 36 and the second spacer 37 may have different dimensions and shapes, but may be the same. As the first spacer 36 and the second spacer 37, a common part, that is, a part having the same size and shape can be used. The first spacer 36 is provided on the lower surface of the first extending portion 42 and contacts the first upper surface portion 21A. The first spacer 36 is disposed between the first upper surface portion 21 </ b> A and the first extension portion 42. The 2nd spacer 37 is provided in the lower surface of the 2nd extension part 47, and contacts the 2nd upper surface part 21B. The second spacer 37 is disposed between the second upper surface portion 21 </ b> B and the second extension portion 47.

The first clamp portion 34 is separated from the first upper surface portion 21 </ b> A of the table 20 by the thickness of the first spacer 36. The second clamp part 35 is separated from the second upper surface part 21 </ b> B of the table 20 by the thickness of the second spacer 37. As a result, a gap having a distance equal to or greater than the thickness of the medium Me is formed between the first clamp part 34 and the first upper surface part 21A and between the second clamp part 35 and the second upper surface part 21B. .

  In the present embodiment, the first spacer 36 is separate from the first member 32 and is attached to the first extending portion 42. The second spacer 37 is separate from the second member 33 and is attached to the second extending portion 47. However, the first spacer 36 and the first member 32 may be integrated, or the second spacer 37 and the second member 33 may be integrated. The first member 32 and the first spacer 36 may be a single article, and the second member 33 and the second spacer 37 may be a single article.

  Although the manufacturing method of the clamp member 30 is not specifically limited, For example, you may utilize insert molding. For example, first, one metal plate is processed to form the first member 32. In addition, the second member 33 is formed by processing another metal plate. Next, the first member 32 and the second member 33 are set in a mold so that the first rising portion 41 and the second rising portion 46 face each other. Then, a resin is poured into the mold, and the leading end portion of the first rising portion 41 and the leading end portion of the second rising portion 46 are joined by the resin. This resin constitutes the base 31. Thereafter, the base 31, the first member 32, and the second member 33 are removed from the mold, and the first spacer 36 and the second spacer 37 are bonded to the back surfaces of the first extension 42 and the second extension 47, respectively. . In this way, the clamp member 30 can be manufactured.

  As shown in FIG. 4, through holes 41 a and 46 a may be formed in portions of the first rising portion 41 and the second rising portion 46 that are covered with the base portion 31. By filling the through holes 41a and 46a with resin, the base 31 can more firmly support the first rising portion 41 and the second rising portion 46. However, the through holes 41a and 46a are not necessarily required.

  FIG. 6A is a view of the clamp member 30 before being attached to the table 20 as viewed from the right side. FIG. 6B is a view of a part of the table 20 to which the clamp member 30 is not attached as viewed from the right side.

  As shown in FIG. 6A, in the clamp member 30 in a state before being attached to the table 20, the angle θ1 formed by the first rising portion 41 and the first extending portion 42 is smaller than 90 °. θ1 <90 °. In the present embodiment, the angle formed by the first rising portion 41 and the first extending portion 42 is equal to the angle formed by the second rising portion 46 and the second extending portion 47. The angle formed by the second rising portion 46 and the second extending portion 47 is also θ1, which is smaller than 90 °. However, it is not particularly limited. The angle formed by the second rising portion 46 and the second extending portion 47 is an angle different from the angle θ1 formed by the first rising portion 41 and the first extending portion 42, and is an angle of less than 90 °. It may be.

  The height from the upper surface of the base 31 to the lower end of the first spacer 36 is H1. The height from the upper surface of the base 31 to the lower end of the second spacer 37 is also H1. On the other hand, as shown in FIG. 6B, the height from the stopper wall 22Bc to the first upper surface portion 21A and the height from the stopper wall 22Cc to the second upper surface portion 21B are H2. Here, H1 <H2. The height from the upper surface of the base portion 31 to the lower end of the first spacer 36 only needs to be smaller than the height from the stopper wall 22Bc to the first upper surface portion 21A, and the height from the upper surface of the base portion 31 to the lower end of the second spacer 37 is sufficient. Is smaller than the height from the stopper wall 22Cc to the second upper surface portion 21B, and their specific numerical values are not limited at all. The height from the upper surface of the base 31 to the lower end of the first spacer 36 may be different from the height from the upper surface of the base 31 to the lower end of the second spacer 37. Further, the height from the stopper wall 22Bc to the first upper surface portion 21A may be different from the height from the stopper wall 22Cc to the second upper surface portion 21B.

[Attaching method of clamp member]
The clamp member 30 can be attached to and detached from the table 20. Next, a method for attaching the clamp member 30 to the table 20 will be described.

  As shown in FIG. 7, when the clamp member 30 is attached to the table 20, the clamp member 30 is slid from the side of the table 20 and inserted into the groove 22. More specifically, the base portion 31 is inserted into a region surrounded by the bottom surface portion 22a, the housing wall portions 22Bb and 22Cb, and the retaining wall portions 22Bc and 22Cc. And the base 31 is pushed in until the 1st clamp part 34 is located above 21 A of 1st upper surface parts, and the 2nd clamp part 35 is located above 2nd upper surface part 21B.

  As described above, the height H1 from the upper surface portion of the base portion 31 to the lower end of the first spacer 36 is smaller than the height H2 from the retaining wall portion 22Bc to the first upper surface portion 21A. The height H1 from the upper surface portion of the base portion 31 to the lower end of the second spacer 37 is smaller than the height H2 from the retaining wall portion 22Cc to the second upper surface portion 21B. Therefore, when the base portion 31 is further pushed in, as shown in FIG. 6C, the first spacer 36 is positioned above the first upper surface portion 21A, and the second spacer 37 is positioned on the second upper surface portion 2B. The first extension part 42 and the second extension part 47 are elastically deformed so as to be positioned above.

  FIG. 6C is a view of the clamp member 30 and the table 20 as viewed from the right when the clamp member 30 is attached to the table 20. When the base portion 31 is pushed into the groove 22 while the first extension portion 42 and the second extension portion 47 are elastically deformed, the upper surface of the base portion 31 comes into contact with the stopper walls 22Bc and 22Cc, and the first and second spacers 36 and 37 are pressed. Are in contact with the first upper surface portion 21A and the second upper surface portion 21B of the table 20, respectively. The elastic force of the first extending portion 42 is applied to the first upper surface portion 21 </ b> A of the table 20 via the first spacer 36. The elastic force of the second extending portion 47 is applied to the second upper surface portion 21 </ b> B of the table 20 via the second spacer 37.

  In the state where the clamp member 30 is attached to the table 20, if the angle formed by the first rising portion 41 and the first extending portion 42 is θ2, the second rising portion 46 and the second extending portion 47 are The formed angle is also θ2. Here, θ2 = 90 °. However, θ2 only needs to be larger than θ1, and is not necessarily 90 °. Further, the angle formed by the second rising portion 46 and the second extending portion 47 may be an angle different from the angle formed by the first rising portion 41 and the first extending portion 42. .

  Since the elastic force of the first extending portion 42 and the second extending portion 47 is applied to the first upper surface portion 21A and the second upper surface portion 21B of the table 20, respectively, it is difficult to slide the clamp member 30 left and right. Therefore, as shown in FIG. 6D, when the clamp member 30 is slid along the groove 22, the boundary B1 between the first rising portion 41 and the first extending portion 42, and the second The boundary B2 between the rising portion 46 and the second extending portion 47 may be slid while being pushed downward. Thereby, only a part of the first spacer 36 comes into contact with the first upper surface part 21A, and only a part of the second spacer 37 comes into contact with the second upper surface part 21B. In addition, since the base portion 31 is pushed down via the rising portions 41 and 46, the base portion 31 is separated from the stopper wall portions 22Bc and 22Cc.

  In addition, the center part of the base 31 is the thin part 31a formed thinly compared with another site | part. Thereby, the base 31 can be bent easily. The thin portion 31 a is preferably formed continuously between the first rising portion 41 and the second rising portion 46.

  After the clamp member 30 is slid to a desired position, the finger is released from the boundary portions B1 and B2 of the clamp member 30. Then, the first spacer 36 is pressed against the first upper surface portion 21A and the second spacer 37 is pressed against the second upper surface portion 21B by the elastic force of the first extending portion 42 and the second extending portion 47. Further, the base portion 31 is pressed against the stopper wall portions 22Bc and 22Cc. Thereby, the clamp member 30 is fixed to the table 20.

  As described above, in the present embodiment, as shown in FIG. 3, the length L5 of the base portion 31 in the left-right direction is the length of the first extending portion 42 in the left-right direction and the length of the first clamp portion 34 in the left-right direction. It is larger than the sum L6 of the thickness and larger than the sum L7 of the length of the second extending portion 47 in the left-right direction and the length of the second clamp portion 35 in the left-right direction. That is, the base 31 is formed relatively long. Since the base 31 is relatively long, the effects described below can be obtained.

  FIG. 8A schematically shows a clamp member 230 having a relatively short length L15 in the left-right direction of the base 231 as an example of another embodiment of the clamp member. In the clamp member 230, the length L15 of the base portion 231 is shorter than the total length L6 in the left-right direction of the first extension portion 42 and the first clamp portion 34. Since other components are the same as those of the clamp member 30 according to the above-described embodiment, the above-described reference numerals are used and detailed description thereof is omitted.

  Since the clamp members 30 and 230 are slidable along the groove 22, as shown in FIG. 6A and FIG. 6B, the width W31 before and after the base portions 31 and 231 is the front receiving wall portion 22Cb. And smaller than the gap G1 between the housing wall 22Bb on the rear side. Therefore, the bases 31 and 231 may be inclined inside the groove 22 when viewed from above.

  FIG. 8B shows a state in which the clamp member 230 is tilted inside the groove 22. FIG. 8C schematically shows the clamp member 30, and FIG. 8D shows a state where the clamp member 30 is tilted inside the groove 22. As shown in FIG. 8B and FIG. 8D, the inclination angle when the base portion 231 of the clamp member 230 is inclined with respect to the center line of the groove 22 is θ3, and the base portion 31 of the clamp member 30 is that of the groove 22. The tilt angle when tilted with respect to the center line is θ4. Then, θ4 <θ3. In other words, the degree of inclination of the clamp member 30 having the long left and right length L5 of the base portion 31 is smaller than that of the clamp member 230 having the short left and right length L15 of the base portion 231. Therefore, according to the clamp member 30 according to the present embodiment, the inclination of the medium Me with respect to the transport direction can be suppressed.

[Control system]
Next, a control system provided in the printer apparatus 10 will be described. As shown in FIG. 10, the printer apparatus 10 sucks air from the carriage drive motor 81 that drives the carriage 12, the feed motor 82 that drives the feed roller 61, and the suction hole 21 h of the table 20, thereby removing the medium Me. A fan 83 sucked on the table 20 and a control device 70 are provided. The control device 70 is communicably connected to the print head 12A, the cutter mechanism 13, the carriage drive motor 81, the feed motor 82, and the fan 83, and controls these operations. The control device 70 includes a printing unit 76, a sheet cutting unit 71, a suction stop unit 72, and a feed unit 73. Processing performed by the printing unit 76, the sheet cutting unit 71, the suction stop unit 72, and the feed unit 73 will be described later.

[Printer operation]
FIG. 11 is a flowchart for explaining an example of the operation of the printer apparatus 10. Next, an example of the operation of the printer device 10 will be described with reference to FIG.

  First, the printing on the medium Me is performed by the printing unit 76 (step S1). The printing unit 76 discharges ink from the print head 12A while moving the carriage 12 in the left-right direction in a state where conveyance of the medium Me is stopped, and rotates the feed roller 61 to move the medium Me by a predetermined length. Repeat the feed operation to carry forward. The printing unit 76 forms an image on the medium Me by repeatedly performing the discharge operation and the feed operation. Hereinafter, the speed at which the medium Me is transported forward during the feed operation during printing is referred to as a print feed speed V1.

  When printing is completed, the sheet cutting unit 71 performs sheet cutting for cutting the medium Me over the entire left and right direction. First, the sheet cut unit 71 starts driving the fan 83 to attract the medium Me to the table 20 (step S2). That is, the suction of the media Me is started. Next, the carriage drive motor 81 is driven to move the blade 13 a of the cutter mechanism 13 along the groove 22. As a result, the rear portion (that is, the upstream portion) of the print portion (the portion on which the image is formed) on the medium Me is cut across the entire left and right direction (step S3). FIG. 12A is a view of the cut medium Me as seen from the side. Since the medium Me is pressed against the table 20 by the first clamp part 34 and the second clamp part 35 of the clamp member 30, the medium Me is prevented from floating from the table 20. Therefore, the medium Me is cut well. Hereinafter, in the cut medium Me, the upstream part is referred to as a first medium Me1, and the downstream part is referred to as a second medium Me2.

  After the sheet cut, the suction stop unit 72 stops the fan 83, the feed unit 73 drives the feed motor 82, and feeds the first medium Me1 forward. The feed unit 73 may start driving the feed motor 82 at the same time as the supply of the drive signal to the fan 83 is stopped. However, even if the supply of the drive signal is stopped, the feed unit 73 may start until the fan 83 stops rotating. It may take a long time. Therefore, in the present embodiment, the feed unit 73 determines whether or not a predetermined time (for example, 2 seconds) has elapsed since the suction stop unit 72 stopped supplying the drive signal to the fan 83 (step S5). The feed motor 82 starts to be driven after a predetermined time has elapsed (step S6). Accordingly, the rotation of the feed roller 61 is started after the suction force with respect to the second medium Me2 has sufficiently disappeared. Further, the feed unit 73 rotates the feed roller 61 at a relatively low speed. When the transport speed of the first medium Me1 at this time is referred to as a low speed feed speed V2, the low speed feed speed V2 is smaller than the print feed speed V1 described above. However, the magnitude of the low speed feed speed V2 is not particularly limited. As shown in FIG. 12B, when the first medium Me1 is conveyed forward by the feed roller 61, the second medium Me2 is pushed forward by the first medium Me1. Accordingly, the second medium Me2 and the first medium Me1 are continuously conveyed forward.

  Incidentally, in the clamp member 30, a gap 51 is formed between the first clamp portion 34 and the second clamp portion 35. Therefore, when the adsorption force with respect to the second medium Me2 remains or when the conveyance speed of the first medium Me1 is relatively high, the first medium Me1 is the second medium as shown in FIG. There is a risk of riding on the media Me2. However, according to the present embodiment, at the time when driving of the feed motor 82 is started, the suction force with respect to the second medium Me2 is sufficiently lost, and the transport speed of the first medium Me1 is relatively small. Therefore, the first medium Me1 can be prevented from riding on the second medium Me2, and the first medium Me1 and the second medium Me2 can be transported satisfactorily (see FIG. 12B). .

  As shown in FIG. 1, in the printer device 10, the front of the table 20 is opened. Therefore, when the separated second medium Me2 is sent forward, the second medium Me2 falls from the table 20 by its own weight as it is. Therefore, in the present embodiment, the first medium Me1 and the second medium Me2 are conveyed forward by rotating the feed roller 61 at a low speed, and then the fan 83 is driven so that the second medium Me2 is moved to the second upper surface of the table 20. Adsorb to the part 21B (step S7). Thereby, the second medium Me2 can be held on the front side portion of the table 20, and the second medium Me2 can be prevented from falling.

  However, when a portion for storing the second medium Me2 is provided below the table 20, or when there is no problem even if the second medium Me2 is dropped, the operation of sucking the second medium Me2 is unnecessary. It is. In this case, the process of step S7 may be omitted.

  Thereafter, the feed motor 82 is driven, and the first medium Me1 is conveyed forward until the front end of the first medium Me1 reaches the next printing start position (step S8). The above is an example of the operation of the printer apparatus 10.

[Effect of the embodiment]
According to the clamp member 30 and the printer device 10 according to the embodiment, various effects can be obtained. Next, effects provided by the clamp member 30 and the printer device 10 according to the present embodiment will be described.

  As shown in FIG. 3, according to the clamp member 30, the first clamp portion 34 that biases the medium Me toward the first upper surface portion 21 </ b> A of the table 20, and the media Me on the second upper surface portion 21 </ b> B of the table 20. A second clamp portion 35 that biases toward the surface is provided, and a gap 51 that is located above the groove 22 of the table 20 is formed between the first clamp portion 34 and the second clamp portion 35. Therefore, the medium Me can be pressed so as not to float from the table 20, and the blade 13 a of the cutter mechanism 13 can be moved along the groove 22 to the end of the medium Me. The medium Me can be cut along the groove 22 while the medium Me is clamped by the clamp member 30. Even when the medium Me is cut across the entire width direction, the blade 13a of the cutter mechanism 13 Interference with the clamp member 30 can be avoided (see FIG. 5). Therefore, it is not necessary to remove the clamp member 30 from the table 20 in order to avoid the interference. Even if the clamp member 30 is not removed from the table 20, the blade 13a can be moved from one end to the other end in the width direction of the medium Me. Therefore, the cutting work of the media Me becomes easy and the time required for the cutting work can be shortened. Therefore, the media Me can be prevented from being lifted and the media Me can be cut easily and quickly.

  Further, according to the clamp member 30, the gap 52 positioned above the groove 22 is also formed between the first rising portion 41 and the second rising portion 46. The blade 13a of the cutter mechanism 13 can also be passed between the first rising portion 41 and the second rising portion 46. Therefore, the blade 13 a can be moved along the groove 22 over the entire left and right direction of the clamp member 30.

  As shown in FIG. 2, the cutter mechanism 13 can move to the home position on the right side of the table 20. That is, the cutter mechanism 13 can move to the outside in the left-right direction with respect to the clamp member 30. According to this embodiment, after the cutter mechanism 13 passes the clamp member 30 and reaches the home position, the blade 13a can be rotated upward.

  The printer device 10 uses media Me having various specifications. The printer device 10 can use a plurality of types of media Me having different widths, and the position of the clamp member 30 in the left-right direction is changed according to the width of the media Me. When the medium Me having a relatively small lateral width is used, the interval between the left and right clamp members 30 is reduced. One of the left and right clamp members 30 is installed on the center side of the table 20 in the left-right direction. However, according to the present embodiment, the blade 13 a can be moved along the groove 22 over the entire left and right direction of the clamp member 30. Therefore, even if the clamp member 30 is disposed on the center side in the left-right direction of the table 20, the blade 13 a does not interfere with the clamp member 30. The clamp member 30 is not limited to the left and right ends of the groove 22 and can be installed at any location.

  The base 31 may be integrated with the first member 32 and the second member 33, but is a separate member from the first member 32 and the second member 33 in this embodiment. According to the present embodiment, by supporting the first member 32 and the second member 33 by the base portion 31, the first member 32 and the second member 33 can be arranged at accurate positions, respectively. For this reason, even when the width of the groove 22 is small, the gap 51 having a predetermined width can be accurately formed between the first clamp portion 34 and the second clamp portion 35, and the first rising portion A gap 52 having a predetermined width can be accurately formed between 41 and the second raised portion 46. Therefore, the blade 13a of the cutter mechanism 13 can be reliably passed through the gaps 51 and 52.

  As shown in FIG. 6A, the first member 32 and the second member 33 supported by the base portion 31 exert a biasing force on the first upper surface portion 21A and the second upper surface portion 21B when attached to the table 20. It is formed in a substantially L shape so that it can be added. However, even if there is a slight error in the angle θ1 between the first member 32 and the second member 33, an urging force can be applied to the first upper surface portion 21A and the second upper surface portion 21B. For this reason, dimensional management is easy.

  Further, the base 31 is formed of a hard resin. Thereby, the base 31 can be easily slid along the groove 22 while being placed in the groove 22. Since the clamp member 30 can be easily moved along the groove 22, the position of the clamp member 30 can be easily adjusted.

  As shown in FIG. 3, the clamp member 30 according to the present embodiment includes a first spacer 36 provided on the lower surface of the first extension portion 42 and a second spacer provided on the lower surface of the second extension portion 47. 37. Accordingly, a gap is inserted accurately between the first clamp part 34 and the first upper surface part 21A and between the second clamp part 35 and the second upper surface part 21B so that the medium Me can be conveyed. can do. Further, the first extension portion 42 and the first clamp portion 34 are prevented from directly contacting the first upper surface portion 21A, and the second extension portion 47 and the second clamp portion 35 are the second upper surface portion. Direct contact with 21B can be prevented. Since the contact area between the clamp member 30 and the table 20 is reduced, the sliding operation resistance can be reduced when the clamp member 30 is slid. Thereby, the high operativity of clamp member 30 is securable. In order to further reduce the resistance of the sliding operation, the first spacer 36 may be formed of a material that is more slippery than the first member 32, and the second spacer 37 may be formed of a material that is more slippery than the second member 33. Good.

  According to the clamp member 30 according to the present embodiment, as shown in FIG. 8C, the length L <b> 5 in the left-right direction of the base 31 is the sum of the first extension 42 and the first clamp 34 in the left-right direction. Is longer than the total length L7 of the second extending portion 47 and the second clamp portion 35 in the left-right direction. Therefore, when the clamp member 30 is slid along the groove 22, the inclination of the base 31 in the groove 22 can be reduced (see FIG. 8D). Thereby, when sliding the clamp member 30, it can suppress that the base 31 becomes resistance of a slide operation. Therefore, high operability of the clamp member 30 can be ensured.

  As shown in FIG. 4, according to the printer device 10 according to the present embodiment, the groove 22 includes the first retaining wall portion 22 </ b> Bd that protrudes toward the second side wall portion 22 </ b> C from the first housing wall portion 22 </ b> Bb, 2 is provided with a second retaining wall portion 22Cd that protrudes toward the first side wall portion 22B from the housing wall portion 22Cb. Therefore, it is possible to prevent the base portion 31 from slipping upward from the groove 22 and to clamp the media Me more reliably.

  According to the printer device 10 according to the present embodiment, the control device 70 includes the suction stop unit 72 that stops the fan 83 after sheet cutting, and the feed unit 73 that drives the feed motor 82 after the fan 83 stops. (See FIG. 10). Therefore, although the gap 51 is formed between the first clamp part 34 and the second clamp part 35 of the clamp member 30, the cut first medium Me1 and second medium Me2 are conveyed forward. At this time, it is possible to prevent the first medium Me1 from riding on the second medium Me2 (see FIG. 12C). Therefore, the cut first media Me1 and second media Me2 can be transported satisfactorily.

  Further, according to the printer device 10 according to the present embodiment, the feed unit 73 controls the feed motor 82 so that the medium Me starts to move when a predetermined time has elapsed after the sheet cut is completed. For this reason, the medium Me can be transported after the suction force by the fan 83 has sufficiently disappeared. Therefore, the cut first media Me1 and second media Me2 can be transported satisfactorily.

  Further, according to the printer device 10 according to the present embodiment, the speed V2 at which the feed unit 73 transports the medium Me is lower than the speed V1 at which the printing unit 76 transports the medium Me. That is, the transport speed V2 of the medium Me after sheet cutting is smaller than the transport speed V1 of the medium Me during printing. Since the medium Me after sheet cutting is transported at a relatively low speed, the first medium Me1 can be prevented from riding on the second medium Me2 (see FIG. 12C), and the first medium Me1 after cutting can be prevented. The first medium Me1 and the second medium Me2 can be transported satisfactorily.

Second Embodiment
Next, another embodiment of the clamp member according to the present invention will be described. FIG. 13 is a cross-sectional view of the clamp member 30A according to the second embodiment, and FIG. 14 is a plan view of the clamp member 30A. Also in the clamp member 30 </ b> A according to the second embodiment, the first member 32 and the second member 33 are configured by a single metal plate. Other basic configurations are the same as those of the clamp member 30 according to the first embodiment. Therefore, in the following description, the same code | symbol is attached | subjected to the part similar or corresponding to 1st Embodiment, and description shall be abbreviate | omitted.

  In the clamp member 30 </ b> A according to the present embodiment, the lower end of the first rising portion 41 and the lower end of the second rising portion 46 are connected by the connecting portion 38. In addition, the front end of the connecting portion 38 protrudes forward, the rear end protrudes rearward, and they serve as a removal preventing portion 39 that prevents the connection portion 38 from coming off.

  Also in the present embodiment, when the boundary portions B1 and B2 are pushed downward, the tips of the first clamp portion 34 and the second clamp portion 35 move upward (see FIG. 6D). In particular, in the present embodiment, the tips of the first clamp part 34 and the second clamp part 35 easily move upward. That is, when the boundary portions B1 and B2 are pushed downward, the vertical gap between the first clamp portion 34 and the first upper surface portion 21A, and the vertical gap between the second clamp portion 35 and the second upper surface portion 21B. Is easy to grow.

  As shown in FIG. 14, the side surfaces of the first extension portion 42 and the second extension portion 47 are parallel to the conveyance direction of the medium Me, but the side surfaces of the first clamp portion 34 and the second clamp portion 35 are the media Me. It is inclined from the transport direction. The side surface of the first clamp portion 34 is inclined so as to be directed toward the first extension portion 42 as it approaches the base portion 31. The side surface of the second clamp part 35 is inclined so as to be directed toward the second extension part 47 as the base part 31 is approached. The length of the first clamp portion 34 in the left-right direction increases as it approaches the tip portion 34a, and the length of the second clamp portion 35 in the left-right direction increases as it approaches the tip portion 35a. Further, when the boundary portions B1 and B2 are pushed downward, the vertical gap between the first clamp portion 34 and the first upper surface portion 21A increases as the tip portion 34a is approached. The gap in the vertical direction between the upper surface portion 21B and the upper surface portion 21B increases as the tip portion 35a is approached. In other words, the first clamp portion 34 and the second clamp portion 35 have a portion in which the gap between the table 20 in the vertical direction is large and the portion on the tip end portion 34a, 35a side is in the left-right direction rather than the portion on the base portion 31 side. Long length. Therefore, when the medium Me is moved in the left-right direction while pushing the boundary portions B1 and B2 downward when attaching the clamp member 30A to the table 20, the media Me has a large gap between the table 20 (tip portions 34a and 35a). Side).

  By the way, in the clamp member 30 (refer FIG. 4) which concerns on 1st Embodiment, there exists a tendency for stress to concentrate on the base 31 in the lower end of the 1st raising part 41 and the lower end of the 2nd raising part 42. FIG. Therefore, if the length of the portion embedded in the base 31 of the first rising portion 41 and the second rising portion 42 is short, the first member 32 and the second member 33 may wobble with respect to the base 31. . On the other hand, in the clamp member 30 </ b> A according to the second embodiment, as shown in FIG. 13, the lower end of the first rising portion 41 and the lower end of the second rising portion 46 are connected by a connecting portion 38. The first rising portion 41, the connecting portion 38, and the second rising portion 42 are integrally formed. The lower end of the first rising portion 41 and the lower end of the second rising portion 42 are connected to the base portion 31. Therefore, the stress at the lower ends of the first rising portion 41 and the second rising portion 42 can be dispersed, and the load applied to the base portion 31 can be reduced. Therefore, the wobbling of the clamp member 30A can be prevented.

  Although the detailed description is omitted, even when the clamp member 30A according to the second embodiment is attached to the table 20 of the printer apparatus 10, the above-described operation can be performed in the printer apparatus 10. Therefore, the clamp member 30A can prevent the media Me from being lifted, and the media Me can be cut easily and quickly. Further, it is possible to prevent the cut first medium Me1 from riding on the second medium Me2, and it is possible to satisfactorily transport both the cut media Me1 and Me2. In addition, the various effects described above can be obtained.

  In the clamp member 30 </ b> A according to the second embodiment, as shown in FIG. 14, the length in the left-right direction of the first clamp portion 34 becomes shorter from the distal end 34 a side toward the base portion 31 side. The area per unit length along the transport direction of the medium Me becomes smaller as the distance from the base portion 31 becomes closer. Similarly, the length in the left-right direction of the second clamp portion 35 becomes shorter from the distal end portion 35a side toward the base portion 31 side. The area per unit length along the transport direction of the medium Me becomes smaller as the distance from the base portion 31 becomes closer. Therefore, the local force with which the first clamp part 34 and the second clamp part 35 press the medium Me becomes weaker as the base part 31 is approached. Therefore, the clamp member 30A according to the second embodiment has a property that the first medium Me1 is more likely to overlap the second medium Me2 when the cut medium Me is transported than the clamp member 30 according to the first embodiment. have. Therefore, the effect of the above-described control by the control device 70, that is, the effect of preventing the two media Me1 and Me2 from being overlapped becomes more remarkable.

<Third Embodiment>
Next, a clamp member and a printer apparatus according to the third embodiment will be described. In the following description, parts that are the same as or correspond to those in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.

  15 is a perspective view of the printer apparatus 10A, FIG. 16 is a front view of the inside of the printer apparatus 10A, and FIG. 17 is a side view of the inside of the printer apparatus 10A.

  As shown in FIGS. 15 and 16, the printer apparatus 10 </ b> A includes a carriage 12 in which a print head 12 </ b> A and a cutter mechanism 13 are accommodated, a housing 100, a table 20, and a pair of left and right that can be attached to and detached from the table 20. And a clamp member 30B. FIG. 15 shows a state where the clamp member 30 </ b> B has been removed from the table 20. 16 and 17 show a state in which the clamp member 30B is attached to the table 20.

  As illustrated in FIGS. 16 and 17, the printer device 10 </ b> A includes a guide rail 15, a carriage drive mechanism 112, a feed roller 61, a feed motor 82, and a pinch roller 62.

  The guide rail 15 is attached to the housing 100 so as to extend in the main scanning direction above the table 20. The carriage drive mechanism 112 reciprocates the carriage 12 along the guide rail 15 in the main scanning direction. A plurality of print heads 12 </ b> A that are vertically opposed to the table 20 and the medium Me are mounted on the carriage 12. The print head 12A is an inkjet head. That is, a plurality of nozzles (not shown) are formed on the lower surface of the print head 12A, and the print head 12A ejects ink from the nozzles toward the medium Me, thereby forming an image on the medium Me.

  As shown in FIG. 17, the feed roller 61 is disposed upstream of the groove 22 in the transport direction. A part of the feed roller 61 is embedded in the table 20, and the upper peripheral surface of the feed roller 61 is exposed from the upper surface of the table 20. Above the feed roller 61, a pinch roller 62 that can be raised and lowered is disposed.

  The cutter mechanism 13 is a mechanism for cutting the media Me. The cutter mechanism 13 includes a driving device 126 and a blade 13a. The driving machine 126 is mounted on the carriage 12. The blade 13 a is connected to the drive device 126. The drive machine 126 is a solenoid or a motor, for example, and drives the blade 13a so as to move up and down with respect to the table 20. The groove 22 described above is formed below the blade 13 a, and the lowered blade 13 a is inserted into the groove 22.

  For example, the cutter mechanism 13 cuts the medium Me after the printing operation. Specifically, the drive device 126 lowers the blade 13a in a state where the conveyance of the medium Me by the feed motor 82 is stopped. The servo motor 116 moves the carriage 12 in the main scanning direction. As the carriage 12 moves, the blade 13a moves in the main scanning direction along the groove 22 to cut the media Me.

  As in the above embodiments, the pinch roller 62 is disposed upstream of the print head 12 </ b> A in the transport direction, so that the media Me may be lifted from the table 20 downstream of the pinch roller 62. In addition, even when the end in the width direction of the medium Me is displaced from the pinch roller 62 in the main scanning direction, the medium Me may be lifted from the table 20. In order to prevent the above, the clamp member 30B presses the end portions on both sides in the width direction of the medium Me against the table 20.

  Next, a detailed configuration of the clamp member 30B according to the third embodiment will be described. 18 and 19 are perspective views of the table 20 and the right clamp member 30B, and FIG. 20 is an enlarged view of a portion 20 in FIG. FIG. 18 shows a state where the clamp member 30B is not attached to the table 20, and FIG. 19 shows a state where the clamp member 30B is attached to the table 20. In FIG. 20, the clamp member 30B attached to the table 20 is indicated by a solid line, and the clamp member 30B removed from the table 20 is indicated by a two-dot chain line. Note that the shape of the left clamp member 30B is bilaterally symmetric with respect to the shape of the right clamp member 30B, and thus detailed description thereof is omitted.

  As shown in FIG.18 and FIG.19, the clamp member 30B which concerns on 3rd Embodiment is comprised by the leaf | plate spring shape | molded by pressing a metal thin plate (for example, stainless steel thin plate). In the present embodiment, the base 31, the first rising part 41, the second rising part 46, the first extending part 42, the second extending part 47, the first clamp part 34, and the second clamp part 35 are: It is an integrally molded product formed by integral molding.

  The first clamp part 34 and the second clamp part 35 are formed in a thin plate shape. A gap 51 is formed between the first clamp part 34 and the second clamp part 35. In a state where the medium Me is pressed, the medium Me is exposed in the gap 51 between the clamp portions 34 and 35.

  The distal end portion 42a of the first extending portion 42 and the distal end portion 34a of the first clamp portion 34 are inclined with respect to the first upper surface portion 21A so as to be directed upward toward the distal end side. The distal end portion 168R on the second clamp portion 35 side of the first clamp portion 34 is also inclined with respect to the first upper surface portion 21A so as to go upward as it goes to the distal end side. The distal end portion 47a of the second extending portion 47 and the distal end portion 35a of the second clamp portion 35 are inclined with respect to the second upper surface portion 21B so as to be directed upward toward the distal end side. The distal end portion 167R of the second clamp portion 35 on the first clamp portion 34 side is also inclined with respect to the second upper surface portion 21B so as to go upward as it goes to the distal end side.

  Through holes 164R and 165R are formed in the second clamp portion 35. By visually confirming the presence or absence of the medium Me through the through holes 164R and 165R, the relative position in the left-right direction of the clamp member 30B with respect to the medium Me can be adjusted. Similarly to the first clamp part 35, a through hole may be formed in the second clamp part 34. Moreover, the same through-hole may be formed in the clamping members 30 and 30A according to the above-described embodiment.

  The base 31, the first rising portion 41, and the second rising portion 46 may be formed in a V-shaped, semicircular arc-shaped, or gate-shaped concave shape, but here, as shown in FIG. , Formed in a bow shape (U-shaped or semi-long arc shape). The groove 22 is also formed in a bow shape. Therefore, the entire base portion 31, first rising portion 41, and second rising portion 46 are likely to fit smoothly along the groove 22.

  As indicated by a two-dot chain line in FIG. 20, when the clamp member 30 </ b> B is disengaged from the groove 22, the width W <b> 1 of the gap 52 between the first rising portion 41 and the second rising portion 46 is the groove 22. Is wider than the width W2 of the upper end (see also FIG. 18). Therefore, as shown by the solid line in FIG. 20, in the state where the clamp member 30B is fitted in the groove 22, the first rising portion 41 and the second rising portion 46 are elastically compressed (also in FIG. 19). reference). As a result, the first rising portion 41 and the second rising portion 46 are fixed to the groove 22 and hardly come off the groove 22.

  As shown in FIG. 20, in the state where the clamp member 30B is detached from the table 20, the first extending portion 42 and the second extending portion 47 are viewed from the left and right directions so as to go upward as they approach each other. Inclined. On the other hand, in a state where the clamp member 30 </ b> B is attached to the table 20, the first extension portion 42 and the second extension portion 47 extend in the left-right direction along the upper surface of the table 20. A downward biasing force is applied to the first extension portion 42 and the second extension portion 47. Thereby, the first clamp part 34 continuous to the first extension part 42 presses the medium Me against the first upper surface part 21A, and the second clamp part 35 continuous to the second extension part 47 holds the medium Me. 2 Press against the upper surface portion 21B.

  As shown in FIG. 17, the longitudinal length of the clamp member 30B, that is, the length from the downstream end to the upstream end of the clamp member 30B is longer than the longitudinal length of the print head 12A. Longer than long. In a state where the clamp member 30B is attached to the table 20, the downstream end of the second clamp part 35 is located in front of the front end of the print head 12A and the front end of the carriage 12, and is located upstream of the first clamp part 34. The end is located behind the rear end of the print head 12 </ b> A and the rear end of the carriage 12. Therefore, the medium Me can be prevented from floating from the table 20 over the entire front and rear direction of the print head 12A and the entire front and rear direction of the carriage 12. Note that the shorter the distance from the feed roller 61 and the pinch roller 62 to the rear end of the first clamp portion 34, the higher the effect of suppressing the media Me from rising.

  Next, a method for attaching the clamp member 30B will be described. First, as shown in FIG. 18, the clamp member 30B is positioned above the side edge Mee of the medium Me, and the posture of the clamp member 30B is determined. Specifically, the base portion 31 is disposed above the groove 22, the first extending portion 42 and the second extending portion 47 are disposed on the right side of the medium Me, and the first clamp portion 34 and the second clamp portion 35. Is placed above the medium Me.

  Then, the clamp member 30 </ b> B is lowered, and the base 31, the first rising portion 41, and the second rising portion 46 are fitted into the groove 22. Thereby, as shown in FIG. 19, the medium Me is sandwiched between the first clamp part 34 and the first upper surface part 21A and between the second clamp part 35 and the second upper surface part 21B. At this time, the medium Me is visually recognized through the through holes 164R and 165R, and the medium Me is pressed by the clamp portions 34 and 35 so that the through holes 164R and 165R overlap the right edge Mee of the medium Me. Thereby, the position of the left-right direction of the clamp member 30B can be determined.

  When the clamp member 30B is fitted into the groove 22, the first rising portion 41 and the second rising portion 46 are arranged so that the distance between the upper portions of the first rising portion 41 and the second rising portion 46 is narrowed. Elastically compressed. Further, the first extending portion 42 and the second extending portion 47 are elastically deformed along the first upper surface portion 21A and the second upper surface portion 21B. The elastic force generated inside the clamp member 30 </ b> B functions as a force by which both the clamp portions 34 and 35 press the media Me against the table 20.

  Although the description is omitted, the left clamp member 30B can be similarly attached to the table 20, and the left end portion of the medium Me can be pressed against the table 20 by the left clamp member 30B.

  When removing the clamp member 30 </ b> B from the table 20, at least one of the first extension portion 42 and the first clamp portion 34, and the second extension portion 47 and the second clamp portion 35 is pulled up. Specifically, for example, the following is performed.

  First, the first clamp part 34 and the first extension part 42 are raised with the base part 31 as a fulcrum by hooking a fingertip or the like on the tip part 34a or the tip part 42a and pulling it upward. Then, the first rising portion 41 is elastically compressed so as to approach the second rising portion 46, and the base portion 31, the first rising portion 41, and the second rising portion 46 come out upward from the groove 22. Thereby, the clamp member 30B can be spaced apart from the table 20 upward. The clamp member 30B can also be easily extracted from the groove 22 by hooking a fingertip or the like on the tip 35a or the tip 47a and pulling it upward.

  The left clamp member 30B can be removed from the table 20 in the same manner.

  According to this embodiment, the same effect as that of the first embodiment can be obtained.

  Although detailed description is omitted, also in the present embodiment, the above-described operation can be performed in the printer apparatus 10A in a state where the clamp member 30B is attached to the table 20 of the printer apparatus 10A. That is, the same printing and sheet cut control as described above can be executed. Accordingly, it is possible to prevent the media Me from being lifted by the clamp member 30B and to easily and quickly perform the cutting operation of the media Me. Further, it is possible to prevent the cut first medium Me1 from riding on the second medium Me2, and it is possible to satisfactorily transport both the cut media Me1 and Me2.

<Fourth embodiment>

Further, a second extension portion 92 is provided on the opposite side of the second extension portion 47 from the second clamp portion 35 side. The 1st extension part 91 and the 2nd extension part 92 are spaced apart in the front-back direction. Other basic configurations are the same as those of the clamp members according to the above embodiments.

  As described above, the cutter mechanism 13 (see FIG. 2) may include a roller for pressing the medium Me. In this case, when the cutter mechanism 13 moves to the left and right, the roller presses the medium Me against the table 20 while rolling on the medium Me. Here, in the clamp members 30, 30A, and 30B according to the first to third embodiments, when the roller moves from the outside toward the center (when moving toward the left in FIGS. 3, 14, and 19). The rollers first abut against the end surface of the portion from the first rising portion 41 to the first extending portion 42 and the end surface of the portion from the second rising portion 46 to the second extending portion 47. A bent portion is provided between the first rising portion 41 and the first extending portion 42 and between the second rising portion 46 and the second extending portion 47. Therefore, resistance is generated when the roller rides on the bent portion, the clamp members 30, 30A, 30B are pushed in the moving direction (left side) of the roller, and the positions of the clamp members 30, 30A, 30B are shifted. Concerned.

  However, according to the clamp member 30 </ b> C according to the present embodiment, the first extension portion 42 and the second extension portion 47 are connected back and forth via the base portion 31, but the first extension portion 91 and the second extension portion 91 are connected to each other. The extension 92 is not connected to the front and rear via the base 31. The 1st extension part 91 and the 2nd extension part 92 are spaced apart in the front-back direction. The first extension 91 and the second extension 92 are more easily elastically deformed than the first extension 42 and the second extension 47. Therefore, when the roller rides leftward and rides on the first extension 91 or the second extension 92, the first extension 91 or the second extension 92 is elastically deformed so that the roller rides up. Can reduce the impact. Therefore, it can suppress that the position of clamp member 30C shifts.
