It is configured to be able to swing between. When the roll paper 6 is replaced, the roll paper 6 is inserted between the pair of side plates 12 from below, and the pair of support arms 14 are pushed up by the upper end surfaces thereof to swing from the support position to the storage position. Thereafter, the pair of support arms 14 swings from the storage position to the support position and is inserted into the core cylinder 4 of the roll paper 6, whereby the roll paper 6 is rotatably supported by the pair of support arms 14.

  A cover portion 18 is supported at the rear upper end portion of the inner side surface of each side plate 12 via a shaft member 16 so as to be swingable in the vertical direction. The cover portion 18 is formed in a substantially flat plate shape, and the tip portion thereof is curved in an arc shape downward. The tip 20 of the cover part 18 functions as a cutting part for cutting the roll paper 6 that has been fed out.

  In addition, a rectangular opening 22 is provided on the distal end side slightly from the center in the depth direction (left and right direction in FIG. 3) of the cover 18. Support portions 24 extending downward are provided at both ends of the opening 22, and the pair of support portions 24 are disposed to face each other. The support portion 24 is provided with a long hole-shaped support receiving portion 26, and the support receiving portion 26 extends obliquely downward with respect to the cover portion 18 in the proximal direction of the cover portion 18. In the present embodiment, the angle θ (see FIG. 3) of the support receiving portion 26 with respect to the cover portion 18 is set to 50 °.

  In the opening portion 22 of the cover portion 18, a feeding roller 28 for feeding the roll paper 6 is disposed. At both ends of the feeding roller 28, cylindrical support shafts 30 extending outward in the axial direction are provided. The support shaft portion 30 of the feeding roller 28 is movably received by the support receiving portion 26 of the support portion 24, whereby the feeding roller 28 is supported on the outer peripheral surface of the roll paper 6 and the cover portion. 18 is configured to be rotatable with respect to 18 and movable in an oblique direction. In the present embodiment, the diameter d (see FIG. 3) of the feeding roller 28 is set to 40 mm, and the distance l that the support shaft portion 30 moves relatively from the upper end portion to the lower end portion of the support receiving portion 26 is 10 mm. Is set. The material of the feeding roller 28 is preferably a material with high grip properties, such as urethane resin, and the surface thereof is preferably subjected to anti-slip processing.

  Next, the usage method of the roll paper holder 2 of this embodiment is demonstrated with reference also to FIGS. First, with reference to FIG.3 and FIG.4, the case where the roll paper 6 is let out in the state with much remaining amount of the roll paper 6 is demonstrated. In a state before the roll paper 6 is fed out, as shown in FIG. 3, the cover portion 18 extends in a substantially horizontal direction, and the tip 20 thereof is in contact with the outer peripheral surface of the roll paper 6. At this time, the support shaft portion 30 of the feeding roller 28 is positioned at the upper end portion of the support receiving portion 26. Further, the feeding roller 28 is supported slightly forward from the top of the roll paper 6.

  When the roll paper 6 is fed out, it is rotated in a predetermined direction (a direction indicated by an arrow B in FIG. 4) while pushing the feeding roller 28 backward with a finger or the like (a direction indicated by an arrow A in FIG. 3). . When the feeding roller 28 is pushed in as described above, the support shaft portion 30 lifts the cover portion 18 while moving relatively from the upper end portion to the lower end portion along the support receiving portion 26 as shown in FIG. In this way, the cover portion 18 is swung upward (in the direction indicated by the arrow C in FIG. 3) by the so-called lever principle, and the tip 20 of the cover portion 18 is separated from the outer peripheral surface of the roll paper 6. When the feeding roller 28 is rotated in the predetermined direction in this state, the roll paper 6 moves in a direction opposite to the predetermined direction (indicated by an arrow D in FIG. 4) due to friction between the feeding roller 28 and the roll paper 6. The leading end portion 32 of the roll paper 6 hangs down. At this time, since the tip 20 of the cover portion 18 is separated from the outer peripheral surface of the roll paper 6, a resistance load does not act on the roll paper 6 by the tip 20 of the cover portion 18 when the roll paper 6 is rotated. The paper 6 can be smoothly rotated.

  Thereafter, when the finger or the like is released from the feeding roller 28, the cover portion 18 is swung downward (in the direction indicated by the arrow E in FIG. 4) by its own weight, and as shown in FIG. 20 is brought into contact with the outer peripheral surface of the roll paper 6. Along with this, the feeding roller 28 is pushed back in the forward direction (the direction indicated by the arrow F in FIG. 4), and the support shaft portion 30 moves relatively along the support receiving portion 26 from its lower end portion to its upper end portion. Is done. In this state, the tip end portion 32 of the roll paper 6 that hangs down is picked up with fingers, the roll paper 6 is fed out, and the roll paper 6 is cut at the tip end 20 of the cover portion 18 while holding the cover portion 18 by hand.

  Next, a case where the roll paper 6 is fed out in a state where the remaining amount of the roll paper 6 is small will be described with reference to FIGS. In the state before the roll paper 6 is fed out, as shown in FIG. 5, the cover portion 18 extends obliquely downward, and the tip 20 of the cover portion 18 is in contact with the outer peripheral surface of the roll paper 6. At this time, the support shaft portion 30 of the feeding roller 28 is positioned at the longitudinal center of the support receiving portion 26.

  When the roll paper 6 is fed out, in the same manner as described above, the feeding roller 28 is pushed backward with a finger or the like (the direction indicated by the arrow G in FIG. 5) while being pushed in a predetermined direction (the arrow H in FIG. 6). Rotate in the direction indicated by. When the feeding roller 28 is pushed in as described above, the cover shaft 18 is lifted while the support shaft portion 30 relatively moves from the longitudinal center portion to the lower end portion along the support receiving portion 26 as shown in FIG. . As a result, the cover 18 is swung upward (in the direction indicated by the arrow I in FIG. 5), and the tip 20 of the cover 18 is separated from the outer peripheral surface of the roll paper 6. When the feeding roller 28 is rotated in the predetermined direction in this state, the roll paper 6 moves in a direction opposite to the predetermined direction (indicated by an arrow J in FIG. 6) due to friction between the feeding roller 28 and the roll paper 6. The leading end portion 32 of the roll paper 6 hangs down.

  Further, when the finger or the like is released from the feeding roller 28, the cover portion 18 is swung downward (in the direction indicated by the arrow K in FIG. 6) by its own weight, and as shown in FIG. Is brought into contact with the outer peripheral surface of the roll paper 6. Along with this, the feeding roller 28 is pushed back in the forward direction (the direction indicated by the arrow L in FIG. 6), and the support shaft portion 30 is relative to the center portion in the longitudinal direction from the lower end portion along the support receiving portion 26. Moved to. In this way, the roll paper 6 can be fed out as described above.

In order to rotate the feeding roller 28 while smoothly pushing it backward, the angle θ of the support receiving portion 26 with respect to the cover portion 18 is preferably 40 to 60 °, and preferably 45 to 55 °. More preferred. If the angle θ is smaller than 40 °, the cover 18 is less likely to swing downward due to its own weight when the fingers are released from the feeding roller 28 after the feeding roller 28 is rotated. If the angle θ is greater than 60 °, the force required to rotate the feeding roller 28 while pushing it backward increases, and the cover portion 18 cannot be smoothly swung upward.

  Referring to FIG. 7, in the roll paper holder 2A of the present embodiment, the support portion 24A includes a first support receiving portion 34 extending in the base end direction of the cover portion 18A and obliquely downward with respect to the cover portion 18A, and A second support receiving portion 36 extending in the distal direction of the cover portion 18A and obliquely downward with respect to the cover portion 18A is provided. The upper end portions of the first and second support receiving portions 34 and 36 are in communication with each other, whereby the first and second support receiving portions 34 and 36 are formed in a substantially inverted V shape as a whole. . In the present embodiment, the angle θ1 of the first support receiving portion 34 with respect to the cover portion 18A and the angle θ2 of the second support receiving portion 36 with respect to the cover portion 18A are each set to 50 °. Further, the distance that the support shaft part 30 moves relatively from the upper end part to the lower end part of the first support receiving part 34 and the distance that the second support support part 36 moves relatively from the upper end part to the lower end part are each 10 mm. Is set.

  In the roll paper holder 2 </ b> A of the present embodiment, the feeding roller 28 can be rotated while being pushed in both the backward direction and the forward direction. In a state before the roll paper 6 is unwound, as shown in FIG. At this time, the support shaft portion 30 of the feeding roller 28 is positioned at each upper end portion of the first and second support receiving portions 34 and 36.

  In the present embodiment, an angle φ with respect to the horizontal direction of a straight line connecting the center of the core tube 4 of the roll paper 6 and the center of the support shaft portion 30 in a state where the cover portion 18A extends in a substantially horizontal direction (see FIG. 7). ) Is set to 70 °. The angle φ is preferably set to 70 to 75 °. By setting the angle φ as described above, the support shaft portion 30 is formed on the core cylinder 4 of the roll paper 6 as the diameter thereof is reduced by using the roll paper 6. Since it moves so as to draw an arc toward the center, when the feeding roller 28 is rotated while being pushed backward (or forward) as will be described later, the feeding roller 28 is moved to the roll paper 6. It can be reliably supported on the outer peripheral surface of the. Further, as the diameter of the roll paper 6 decreases as the roll paper 6 is used, the angle of the first support receiving portion 34 with respect to the horizontal is relatively small, and the angle of the second support receiving portion 36 with respect to the horizontal becomes relatively large. It is easy to rotate the feeding roller 28 while pushing it backward (or forward). Also in the first embodiment, the above-described effects can be achieved by setting the angle φ to 70 to 75 °.

  First, with reference to FIGS. 7 and 8, a method of rotating the feeding roller 28 while pushing it backward (in the direction indicated by the arrow M in FIG. 7) will be described. When the roll paper 6 is fed out, it is rotated in a predetermined direction (rearward direction indicated by an arrow N in FIG. 8) while pushing the feeding roller 28 backward with fingers or the like. When the feeding roller 28 is pushed in as described above, as shown in FIG. 8, the support shaft portion 30 lifts the cover portion 18 </ b> A while moving relatively from the upper end portion to the lower end portion along the first support receiving portion 34. . As a result, the cover portion 18A is swung upward (in the direction indicated by the arrow O in FIG. 7), and the tip 20 of the cover portion 18A is separated from the outer peripheral surface of the roll paper 6. When the feeding roller 28 is rotated in the predetermined direction in this state, the roll paper 6 is moved in a direction opposite to the predetermined direction (front direction, in FIG. 8) due to friction between the feeding roller 28 and the roll paper 6. In the direction indicated by the arrow P), the leading end 32 of the roll paper 6 hangs down.

  Thereafter, when a finger or the like is released from the feeding roller 28, the cover 18A swings downward (in the direction indicated by the arrow Q in FIG. 8) by its own weight, and as shown in FIG. 7, the tip of the cover 18A Is brought into contact with the outer peripheral surface of the roll paper 6. Along with this, the feeding roller 28 is pushed back in the forward direction (the direction indicated by the arrow R in FIG. 8), and the support shaft portion 30 is relative to the upper end portion from the lower end portion along the first support receiving portion 34.
