Description

  The present invention relates to a roll paper holding structure, and more particularly to a roll paper that is rotatably suspended by a cantilever structure.

  There is a conventional roll paper holding structure in which a roll paper is rotatably suspended by a cantilever structure (for example, Patent Document 1).

  FIG. 9 is a front view of this type of conventional roll paper holding structure. The roll paper holding structure 40 includes a horizontal paper holding rod 41 that holds the roll paper b. On the upper surface of the paper suspension rod 41, restricting plates 42a and 42b are provided so as to contact the side surface of the roll paper b and position the roll paper b. In such a roll paper holding structure 40, the roll paper b is attached and detached from the open end side (right side in the figure) of the paper suspension rod 41. At this time, the open end that supports the roll paper b from the open end side. Since the side regulating plate 42a gets in the way, the open end side regulating plate 42a has to be removed from the paper suspension rod 41 every time the roll paper b is attached / detached, and it takes time to attach / detach the roll paper b.

  For this problem, the roll paper can be attached and detached without removing the open end side restricting plate by increasing the inner diameter of the roll paper or reducing the height of the open end restricting plate. Since the inner diameter of the roll paper and the height of the open end side regulation plate are severely restricted, a practical one cannot be obtained.

  The present invention has been made in view of the present situation, and an object of the present invention is to provide a roll paper holding structure that has a roll paper holding function similar to that of the conventional configuration and that can easily attach and detach the roll paper. .

  The present invention provides a horizontal paper suspension rod having a fixed end on one side and an open end on the other side, and a roll paper that is loosely fitted from the open end, and a top surface of the paper suspension rod. A roll paper holding structure comprising an open end side restricting plate that stands up from the open end side and supports the side surface of the roll paper loosely fitted on the paper holding rod from the open end side. It is pivotally supported so that it can be tilted to the open end side of the ridge, and the lower end portion of the open end side restricting plate is in its standing state, along the upper surface of the paper suspending ridge, in the direction of the fixed end of the paper suspension ridge A support seat piece that extends to the support seat piece is supported. When the roll paper is being held, the inner peripheral surface of the roll paper is placed on the support seat piece, so that the open end side regulation plate is supported in an upright state A roll paper holding structure.

  According to this configuration, the open end side restricting plate can be converted from the standing state to the tilted state, and if the open end side restricting plate is tilted, the roll paper can be attached and detached without removing the open end side restricting plate. It becomes. On the other hand, in the holding state of the roll paper, since the open end side restricting plate is supported in the standing state by the weight of the roll paper, even if the roll paper presses the open end side restricting plate to the side, the open end side restriction is performed. The plate securely supports the side of the roll paper without tilting.

  Specifically, when the roll paper is loaded, the roll paper is pushed into the paper suspension rod with the open end side regulating plate tilted. At this time, since the open end side restricting plate is inclined, even when the open end restricting plate is high, the roll paper can be pushed in without colliding with the open end restricting plate. In the tilted state of the open end side restricting plate, the support seat piece extends upward, but the support seat piece functions sufficiently even if it is shorter than the open end side restricting plate. There is no obstacle to paper loading.

  When the roll paper is pushed into a required position, the open end side regulation plate is raised and brought into contact with the side surface of the roll paper. Then, in this state, the inner peripheral surface of the roll paper is placed on the support seat piece of the open end side regulation plate, and the roll paper is suspended by the paper suspension rod. In this state, the support seat piece is pressed against the roll paper, whereby the open end side restricting plate is held in the upright state, and the roll paper is supported from the side by the standing open end side restricting plate.

  On the other hand, when removing the loaded roll paper, it is only necessary to lift the roll paper lightly and move it horizontally to the open end side of the paper suspension rod. That is, when the roll paper is lifted, the support seat is released from the weight of the roll paper and the open end side restricting plate can be tilted. From this state, if the roll paper is moved to the open end side, the open end side The regulating plate is pressed against the roll paper and tilted, and the roll paper can be pulled out from the paper suspension rod.

  In addition, when the roll paper is pulled out from the paper suspension rod, the open end side regulation plate is tilted, so that a new roll paper can be directly fitted into the paper suspension cage without tilting the open end side regulation plate. be able to.

  The open end side restricting plate according to the present invention can be directly supported on the paper suspension rod or can be supported on another member attached to the paper suspension rod. For example, an open end side sliding substrate provided on the upper surface of the paper suspension rod so as to be slidable along the longitudinal direction of the paper suspension rod is provided. A configuration is proposed in which the plate is tiltably mounted. Such a roll paper holding structure can hold roll paper of various widths by sliding the open end side sliding substrate.

  Thus, according to the roll paper holding structure of the present invention, the roll paper can be easily attached / detached without removing the open end side regulating plate. Further, the roll paper holding structure of the present invention is not limited in the inner diameter of the roll paper or the height of the open end side regulation plate, and is highly practical. In addition, since the tilting and standing of the open end side regulation plate can be performed in conjunction with the roll paper attaching / detaching operation, the roll paper can be attached and detached easily and in a short time. Further, when the roll paper is held, the open end side regulation plate is supported in an upright state by the weight of the roll paper, so that even if the roll paper is large and heavy, the side surface can be firmly supported. Further, such a roll paper holding structure has an advantage that the structure is simple and can be realized at low cost.

  The roll paper holding structure of the present invention can be suitably disposed in a printer, a roll paper stand that supplies recording paper to the printer, and the like. Hereinafter, an embodiment in which the present invention is applied to a roll paper stand will be described.

  1 to 3 are a front view, a side view, and a plan view of a roll paper stand 1 having the roll paper holding structure of the present invention.

  The roll paper stand 1 includes a base 3 placed on a floor surface and the like, and a vertically long plate-like side plate 4 standing on the left rear portion of the base 3. The roll paper holding structure 2 protrudes rightward from the upper right side surface of the side plate 4. The base 3, the side plate 4, and the roll paper holding structure 2 are mainly composed of stainless steel plate pieces that are processed by sheet metal.

  A printer a suitable for the roll paper stand 1 is placed on the base 3. The roll paper holding structure 2 is located above the rear part of the printer a placed. As shown in FIG. 2, the roll paper b is held in the roll paper holding structure 2, and the paper roll wound around the roll paper b protrudes from the lower right side surface of the side plate 4. 5 is taken into a paper feed port c opened on the back of the printer a. When the printer a pulls in the paper d from the paper feed opening c, the roll paper b rotates around the paper suspension rod 10 in the direction of the arrow in the figure, and the paper d is sequentially supplied to the paper feed c.

  As shown in FIG. 4, the roll paper holding structure 2 includes a horizontal paper holding rod 10 having a left end fixed to the upper portion of the side plate 4 and a roll paper b that is loosely fitted from the right end. An open end side restricting plate 11 and a fixed end side restricting plate 12 that support the side surface of the roll paper b loosely fitted in the paper suspension rod 10 are provided.

  The paper suspension rod 10 is a bowl-shaped plate piece formed by pressing a stainless steel plate. As shown in FIG. 4, the paper suspension rod 10 has a left end screwed into the upper portion of the side plate 4 and protrudes rightward, and a right end is open. That is, the left end of the paper suspension rod 10 corresponds to a fixed end, and the right end corresponds to an open end. The side cross-sectional shape orthogonal to the length direction of the paper suspension rod 10 has the same shape. As shown in FIG. 5, the side cross-sectional shape is a size that can fit within the inner diameter of the roll paper b. As shown in FIG. 5, the upper surface of the paper suspension rod 10 is composed of a front upper surface portion 10 b that is inclined forward and a rear upper surface portion 10 c that is inclined downward, and in the central portion of the front and rear width thereof, A convex refracting portion 10a is formed. As shown in FIG. 2, the roll paper b mounted on the paper suspension rod 10 is suspended at the front and rear end portions of the bending portion 10 a and the paper suspension rod 10.

  As shown in FIG. 4, the front upper surface portion 10 b of the paper suspension rod 10 is provided with a long and narrow guide groove 15 extending through the stainless steel plate and extending in the longitudinal direction of the paper suspension rod. Then, two thin plate-like sliding substrates 16 and 17 that slide along the guide groove hole 15 on the front upper surface portion 10 b are attached to the paper suspension rod 10. A guide pin 20 that protrudes downward and fits into the guide groove 15 is screwed to the center of each of the sliding substrates 16 and 17. Of the two sliding boards 16 and 17, the open end side sliding board 16 attached to the right side is provided with the open end side regulation plate 11, and the fixed end side sliding board 17 attached to the left side includes The fixed-end-side regulating plate 12 is disposed, and the standing positions of the regulating plates 11 and 12 can be adjusted by sliding the sliding substrates 16 and 17. Further, a fastening member comprising an upper knob screw 22 and a lower presser plate 23 is attached to each sliding board 16, 17. When the upper knob screw 22 of each sliding board 16, 17 is tightened, the sliding board 16 , 17 become non-slidable, and the standing positions of the restriction plates 11, 12 are fixed.

  The fixed end side restricting plate 12 has a vertically long plate shape, and is erected from the right end edge of the fixed end side sliding substrate 17 in a direction orthogonal to the front upper surface portion 10 b of the paper suspension rod 10. This fixed end side restricting plate 12 is provided integrally with the fixed end side sliding substrate 17, slides to the left and right together with the fixed end side sliding substrate 17, and contacts the left side surface of the roll paper b at a required position. Thus, the roll paper b is supported from the left side.

  As shown in FIG. 4, the open end side restricting plate 11 is attached to the left end edge of the open end side sliding substrate 16 via a hinge 18 in contact with the right side surface of the roll paper b. The open end side restricting plate 11 tilts to the right so as to follow the standing state (FIG. 6A) that stands in a direction perpendicular to the front upper surface portion 10b of the paper suspension rod 10 and the front upper surface portion 10b. It can be converted into a tilted state. The open end side regulation plate 11 functions to support the roll paper b from the right side by sliding to the left and right together with the open end side sliding substrate 16 and contacting the right side surface of the roll paper b at a required position. As shown in FIG. 5, the open end side restricting plate 11 is formed with a circular through hole 21 through which the upper knob screw 22 passes so as to be able to tilt without colliding with the upper knob screw 22.

  As shown in FIG. 6A, the open end side restricting plate 11 is provided with a short plate-like support seat piece 13 extending leftward from the lower end in the standing state. The support seat piece 13 extends along the front upper surface portion 10b of the paper suspension rod 10 in the standing state of the open end side regulation plate 11, and the support seat piece 13 in the holding state of the roll paper b. When the inner peripheral surface of the roll paper b is pressed against the upper side, the open end side regulation plate 11 is supported so as not to tilt to the right. The open end side restricting plate 11 and the support seat piece 13 are formed of an integral L-shaped stainless piece, and as shown in FIG. 6B, when the open end side restricting plate 11 is tilted to the right, Along with this, the support seat 13 rotates upward and stands up so as to be orthogonal to the front upper surface portion 10 b of the paper suspension rod 10. Here, the extension length of the support seat piece 13 is about one fifth of the height of the open end side restricting plate 11, and as shown in FIG. 5, the open end side restricting plate 11 is in a tilted state. Thus, the roll paper b can be pushed into the back of the paper suspension rod 2 without colliding with the open end side regulation plate 11 and the support seat piece 13. When the open end side restricting plate 11 is in the standing state (FIG. 6A), the open end side restricting plate 11 is moved to the left by the support seat piece 13 coming into contact with the front upper surface portion 10a of the paper suspension rod 10. It becomes impossible to lean towards.

  Next, a method for loading the roll paper b will be described.

  First, before loading the roll paper b, if necessary, the upper knob screw 22 is loosened, and the regulating plates 11 and 12 are slid and fixed to positions suitable for the width of the roll paper b (see FIG. 4).

  With the open end side regulation plate 11 tilted to the right, the roll paper b is fitted into the paper suspension rod 10 from the open end (see FIG. 7A). In this case, the open end side restricting plate 11 is tilted along the front upper surface portion 10b of the paper suspension rod 10, and the support seat piece 13 stands up, but the open end side restricting plate. Therefore, the roll paper b can be fitted to the back of the paper suspension rod 10 without colliding with the open end side regulation plate 11 or the support seat piece 13.

  When the roll paper b is fitted to the vicinity of the fixed end side restricting plate 12, the support seat piece 13 is tilted to the left so that the roll paper b is hooked on the support seat piece 13, thereby restricting the open end side restriction that has been tilted. The plate 11 is raised and brought into contact with the right side surface of the roll paper b (see FIG. 7B). Finally, the roll paper b is suspended on the paper suspension rod 10 so that the inner peripheral surface of the roll paper b is placed on the support seat 13 (see FIG. 7C). In such a state, the support seat piece 13 is pressed by the weight of the roll paper b, and the open end side regulation plate 11 is supported in an upright state. At the same time, the roll paper b is supported by the regulation plates 11 and 12 on both sides, and is held rotatably around the paper suspension rod 10 without swinging left and right.

Next, a method for removing the roll paper b will be described.
When removing the roll paper b attached to the roll paper holding structure 2, the roll paper b is first lifted (see FIG. 8A). Thereby, the support seat piece 13 is released from the weight of the roll paper b, and the open end side regulation plate 11 can be tilted. Subsequently, when the roll paper b is moved to the right (see FIG. 8B), the open end side regulation plate 11 is pushed by the roll paper b to be tilted, and the roll paper b is moved to the right as it is. By doing so, the roll paper b can be extracted from the paper suspension rod 10 (see FIG. 8C).

  Thus, according to the roll paper holding structure 2 of the present embodiment, the roll paper b can be attached and detached without removing the open end side regulation plate 11. Further, since the open end side restricting plate 11 is tilted when the roll paper b is attached or detached, the inner diameter of the roll paper b or the height of the open end side restricting plate 11 is not limited. Further, since the open end side regulating plate 11 can be tilted or raised by pushing the open end side regulating plate 11 with the roll paper b or hooking the support seat piece 13 when attaching or detaching, the roll paper b can be attached and detached easily and in a short time. In the holding state of the roll paper b, the open end side restricting plate 11 is supported in an upright state by the weight of the roll paper b, so that the open end side restricting plate 11 firmly supports the roll paper b from the right side. it can. Further, the roll paper holding structure 2 can be realized at a low cost because it can be realized by a relatively small part change in the conventional roll paper holding structure 40 as shown in FIG.

  The roll paper holding structure in the present invention is not limited to the embodiment described above, and various changes can be made without departing from the scope of the present invention.

  For example, in the above embodiment, the open end side regulation plate 11 is attached to the open end side sliding substrate 16 and is slidable along the longitudinal direction of the paper suspension rod 10. The end side regulating plate 11 can be directly attached to the upper surface of the paper suspension rod 10. The fixed end side regulating plate 12 can be replaced by the side plate 4. Moreover, in the said Example, although the open end side regulation board 11 is made to incline substantially horizontally, it should just incline so that the roll paper b can pass, and does not necessarily need to incline horizontally. In the embodiment, the present invention is applied to a roll paper stand. However, the roll paper holding structure of the present invention can also be applied to a roll paper holding structure provided in a printer.
