Description

  This invention relates to a roll paper holder.

  Conventional commercially available roll paper holders are simply held vertically or horizontally. Although a paper cutting mechanism has been tried, there is no practically completed product that is pulled out if it cannot be cut and slips out or the roll paper comes off from the holding parts. (Figure 2)

  However, according to the above technique, the holder fluctuated or moved and fell when the paper was pulled. Also, it was necessary to use both hands for cutting the paper to hold and tear both sides of the perforation. Therefore, the present invention has an object to provide a mechanism for holding the roll paper in a stable state until the paper is used up, and a mechanism for easily and cleanly cutting the paper with one hand by pulling the paper forward and pulling it downward. And

  In order to solve the above problems, a roll paper holder according to claim 1 is a bracket, a holding shaft that is rotatably supported by the bracket, and holds the roll paper, and is held by the holding shaft. A positioning shaft rotatably supported by the bracket so that the outer peripheral surface of the roll paper is in contact with the outer peripheral surface thereof, and a pivot shaft rotatably supported by the bracket so that the rear end portion can be in contact with the outer peripheral surface of the positioning shaft. It is characterized by comprising flaps that are made.

The roll paper holder according to claim 2, wherein a stopper pin is fixed in the vicinity of a rear end portion of the flap so as to be set in a groove provided on an outer peripheral surface of the positioning shaft, and the rear end portion of the flap One end of a spring is fixed to the flap so that a clearance between the positioning shaft and the outer peripheral surface of the positioning shaft is secured, and the other end of the spring is locked in a groove of the positioning shaft.

  The roll paper holder according to claim 3 is characterized in that the outer peripheral surface of the positioning shaft is knurled, and the tip of the stopper pin is cut obliquely.

  The roll paper holder according to claim 4 is provided with substantially U-shaped or substantially L-shaped bearing portions whose one ends are released on both side walls of the bracket, and the holding shafts are provided at both ends of the holding shaft. It is supported by a bearing portion of the bracket via a guide slot.

  The roll paper holder according to claim 5 is characterized in that three grooves are provided in the longitudinal direction of the outer peripheral surface of the positioning shaft, and three stopper pins are fixed in the vicinity of the rear end portion of the flap. . Thus, the present invention inserts the heavy holding shaft (3) into the roll paper (1), and loads the bracket (4) so as to ride on the positioning shaft (7). It is a mechanism to maintain. Also, with one hand, pulling the paper forward and pulling it downward, the roll paper (1) is rotated by sandwiching the roll paper (1) due to the gravity applied to the holding shaft (3) and the rotation of the positioning shaft (7). It is a mechanism that can cut the paper neatly along the perforation by stopping the movement of the surface of the paper by stopping the stopper and preventing the stopper pin from slipping (8).

  As shown in (Fig. 1), this holder holds a stable state even when the paper is pulled out by loading roll paper into the bracket, and it can be easily pulled out with one hand and pulled downward. It also has a mechanism that can cut paper neatly.

One embodiment of this device is shown in FIG. The side from which the paper is drawn out is defined as the front side, and the left side as viewed from the front side is indicated by A and the right side is indicated by B (the central part is C).
The roll paper (1) is rotatably controlled by a substantially U-shaped bearing portion (6A) (6B) having one end opened on both side walls (5A) and (5B) of the bracket (4). The bracket (4) is loaded by the holding shaft (3) with the guide slots (2A) (2B) and is put on the positioning shaft (7).

  The positioning shaft (7) is disposed below the bearing portions (6A) and (6B) of the holding shaft (3) provided on both side walls (5A) and (5B) of the bracket (4). Both ends are pivotally supported by bearing holes (7A) (7B) provided at positions slightly apart from 6B), and are rotatably provided.

  As a mechanism for stopping the movement of the roll paper (1) in the vicinity of the open end of the bracket (4) (8A) (8B) in front of the positioning shaft (7), the flap (9) can be rotatably supported ( 10A) (10B). At the same time, the flap (9) has a mechanism for stopping the rotation of the positioning shaft (7) as will be described later.

Near the rear end of the flap (9), it is set in the three grooves (11A), (11B), and (11C) provided in the left, right, and center portions of the positioning shaft (7). Three stopper pins (12A), (12B), and (12C) that are cut are fixed, and the rear end (9a) of the flap (9) is usually at a position away from the surface of the positioning shaft (7). (FIG. 3) At the same time, this state does not hinder the rotation of the positioning shaft (7).

  When the paper is pulled out, the stable state is maintained, and even with one hand, the paper is pulled forward and pulled downward, so that the flap (10A) (10B) is used as a rotation fulcrum as shown in FIG. ) When the front side is lowered, the rear end of the flap (9) is moved upward, and the rear end (9a) of the flap comes into contact with the knurled outer peripheral surface (7a) of the positioning shaft (7) to rotate the shaft (7). Stop. At the same time, the stopper pins (12A), (12B), and (12C) also move upward, and the tip of the pins sticks to the paper surface to fix the position of the paper.

  With the above functions, the movement of the paper is stopped, and a mechanism that can cut the paper easily and cleanly along the perforation is realized.

  The torsion springs (13A) and (13B) are twisted in order to secure the clearance between the rear end portion (9a) of the flap (9) and the outer peripheral surface (7a) of the positioning shaft (7) and stabilize the movement of the flap (9). Fixing to the flap (9) via the latching portion (15) of the spring bracket (14), passing the spring arm over the groove (11c) portion of the positioning shaft (7) and locking it to the shaft (7) Thus, an appropriate tension is applied between the flap (9) and the positioning shaft (7). (See Figures 1 and 3)

  The positional relationship of each member is as follows as shown in FIG. With respect to the axis of the holding shaft (3) loaded in the bracket (4), the axis of the positioning shaft (7) has a roll paper core diameter from the vertical center of the substantially U-shaped bearing portions (6A) (6B). , And the positional relationship below the substantially U-shaped bearing portions (6A) and (6B). The axis of the finishing axis of the flap (9) is located in the (8A) (8B) direction position near the open end of the bracket (4) from the positioning shaft (7).

"Example"
According to this embodiment, as shown in FIG. 1, the holder always holds a stable state even when the paper is pulled out by loading the roll paper into the bracket via the holding shaft. However, you can cut the paper easily and cleanly by pulling the paper toward you and pulling it down.

"Other examples"
In the embodiment of FIG. 1, the positioning shaft is prevented from slipping (rotation prevention), and the rear end of the flap is applied to the knurled outer peripheral surface (7 a) of the positioning shaft. Also, a file-like plate (paper) or the like can be installed on the surface. Moreover, it can also be set as the structure which provides a nail | claw in the rear-end part of a flap and makes it engage with the outer peripheral surface (7a) of the shaft (7) knurled.

  As a mechanism for stopping the movement of the paper itself, in the above-described embodiment, the tip of the stopper pin is cut obliquely to protrude the paper itself. As shown in FIGS. 8 and 9, a comb having an area at the tip of the pin is used. It is also possible to provide a configuration in which a block or a bowl-shaped block is provided, or a mountain-shaped rubber plate is attached to the block.

  Further, the front edge shape of the flap is not only cut by a straight line but also a shape in which the center is projected as shown in FIG. 4, and conversely, when the paper is drawn downward as a wavy shape in which the center is drawn as shown in FIG. It can also be set as the structure which adjusts the position and area of a surface.

  Further, in the embodiment of FIG. 1, a holder to be installed on a vertical wall surface is provided, but a holder to be installed on a horizontal bottom surface of a shelf provided above the head can be provided by adopting a substantially L-shaped bearing portion. . (See Figure 5)

  This is a technology that can be used as a holder for all types of “rolls” by adjusting the installation position and number of stopper pins for the roll width, quality and thickness of the roll paper.

  It is possible to provide a paper holder having a mechanism that can hold a roll paper in a stable state at all times and appropriately cut the paper. As long as it is rolled, it can be applied to a roll of a material such as PVC, nonwoven fabric or film.
