Moreover, FIG. 3 is sectional drawing of the roll paper holder which concerns on Example 1 of this invention. FIG. 3 is a cross-sectional view taken along line AA in FIG.
As shown in FIGS. 1 and 2, the roll paper holder 1 </ b> A according to the first embodiment includes a container portion 2 including a front container portion 2 a having a hollow portion 3 for mainly containing roll paper 27 and a rear container portion 2 b. The paper cutting mechanism 8 is used to cut the drawn piece of the roll paper 27 led out of the container part 2 through the roll paper lead-out part 23 of the container part 2.
Further, in the roll paper holder 1A according to the first embodiment, the front container part 2a and the rear container part 2b constituting the container part 2 are connected through a hinge 5 having a second pivot 4, and the front container part 2a. Are connected via a second pivot 4 (hinge 5) (see FIG. 3 described later), and the second pivot 4 is tilted about the base axis. Since the front container part 2a is tilted and opened by its own weight, in order to keep the front container part 2a closed, the locking tool 11 is disposed on the front container part 2a, and the upper end of the front container part 2a. The locking claw 18 formed in the portion and the locking arm 11a of the locking tool 11 are engaged to close the front container part 2a and the rear container part 2b.

Further, the locking tool 11 holds the paper retaining roller 10 in the locking arm 11a, and is fixed to the second shaft 9 disposed vertically above the locking tool 11, so that the second shaft The locking tool 11 and the locking arm 11a tilt with the rotation of 9, and the locking state of the locking arm 11a and the front container part 2a is released.
The second shaft 9 is supported by side plates 6a and 6b that are disposed so as to sandwich the container portion 2 from the left and right side surfaces (see FIG. 1). The end of the second shaft 9 that protrudes on the side plate 6 a through the side plate 6 a that is disposed is connected to the arm rod 13 via the connecting portion 17, and is connected via the connecting portion 17. The power from the arm rod 13 is transmitted, and the second shaft 9 is rotated in the circumferential direction.
The connecting portion 17 is, for example, a structure in which a power transmission plate 17a and a power transmission plate 17b are connected to each other by a connecting pin 17d so that they can be tilted to each other. The rod 13 is attached to the rod 13 via a connecting pin 17c so as to be able to tilt with respect to each other. On the other hand, the end of the connecting portion 17 on the side of the power transmission plate 17b is fixed to the second shaft 9 protruding through the side plate 6a. ing. With such a configuration, as the arm rod 13 tilts, the power is transmitted to the second shaft 9 via the connecting portion 17, and the second shaft 9 rotates in the circumferential direction.

The arm rod 13 is attached to the side surface of the side plate 6a on the side where the front container portion 2a is not disposed via the rotation shaft 12 so as to be tiltable with the rotation shaft 12 as a base axis. An elastic body 14 made of, for example, a helical spring or rubber is connected so as to connect the end portion 13a (the end portion on the side where the rear container portion 2b is disposed) and the latching portion 34 protruding on the side plate 6a. It is hooked and urged so as to push down one end 13a of the arm rod 13 vertically downward.
At this time, since the side plate 6a is integrally attached to the side surface of the rear container portion 2b with screws, an adhesive or the like, one end portion 13a of the arm rod 13 is substantially connected to the rear container portion 2b. It can be said.
In other words, in the roll paper holder 1A according to the first embodiment, the front container part 2a and the rear container part 2b constituting the container part 2 are connected to each other through the second pivot 4 (described later). In this state, the front container part 2a tilts and opens due to its own weight and does not close, so that the locking claw 18 forms an engaging structure at the upper end of the front container part 2a. The tool 11 (locking arm 11a) is indirectly connected to the rear container part 2b via the arm rod 13 so that the front container part 2a and the rear container part 2b are closed.

  In the roll paper holder 1A according to the first embodiment, the paper cutting mechanism 8 for cutting the drawn piece of the roll paper 27 led out from the container part 2 is provided on the roll paper lead-out part 23 side of the front container part 2a. The paper cutting mechanism 8 is arranged not only for cutting the roll paper 27 but also for opening the front container part 2a constituting the container part 2.

Here, the paper cutting mechanism 8 will be described in detail with reference to FIGS.
The paper cutting mechanism 8 of the roll paper holder 1A according to the first embodiment has a flat plate shape, and the first shaft 7 is fixed directly or indirectly on the upper end side of the support plate 19 larger than the width of the roll paper 27. The support plate 19 is provided with a tilting plate 22 at the lower end of the support plate 19 that tilts with the first pivot 20 as a base axis via the first pivot 20 (hinge 21). Moreover, the support plate 19 and the tilting plate 22 are provided with a part which overlaps with the support plate 19 in the state which these drooped. In addition, the mechanism by which the lead-out piece of the roll paper 27 is cut by the paper cutting mechanism 8 will be described later.
Further, the first shaft 7 of the paper cutting mechanism 8 is disposed in the vicinity of the roll paper lead-out portion 23 of the front container portion 2a in a non-contact manner with the front container portion 2a. At this time, the first shaft 7 is supported by the side plates 6a and 6b disposed on the left and right side surfaces of the container portion 2, and the end portion of the first shaft 7 on the side plate 6a side penetrates the side plate 6a. , Projecting on the side plate 6a.

Here, the relationship between the front container part 2a, the rear container part 2b, and the side plates 6a and 6b will be described.
As described above, the bottom part of the front container part 2a and the rear container part 2b are connected via the second pivot 4, and the rear container part 2b, the side plate 6a, and the side plate 6b are screws or adhesives. Etc. are fixed integrally. Accordingly, although the rear container part 2b sandwiched between the side plates 6a and 6b cannot be moved, the front container part 2a connected to the rear container part 2b via the second pivot 4 has the side plates 6a and 6b. Also, the second pivot 4 can be tilted about the base axis.
In the present embodiment, the case where the rear container portion 2b and the side plates 6a and 6b are provided as separate configurations has been described as an example. However, the configuration of the container portion 2 and the side plates 6a and 6b is illustrated in FIG. It is not necessary to be limited to what is described in thru | or 10, It is set as the form which protruded the both sides | surfaces of the back container part 2b to the front container part 2a side, and inside of the both sides of the back container part 2b which protruded the front container part 2a You may comprise so that it may have a width | variety smaller than a dimension, and this front container part 2a may be connected to the rear container part 2b via the 2nd pivot 4. FIG. In this case, the 2nd axis | shaft 9 and the 1st axis | shaft 7 will be supported by the side surface which protruded from the back container part 2b.

Returning to the description of the paper cutting mechanism 8 again, a pressing arm 16 is fixed to the end of the first shaft 7 protruding from the side plate 6 a in the paper cutting mechanism 8 while protruding from the outer surface of the first shaft 7. The push-down arm 16 is tilted as the first shaft 7 rotates.
That is, as the support plate 19 of the paper cutting mechanism 8 tilts, the push-down arm 16 provided at the end of the first shaft 7 tilts.
Then, the push-down arm 16 tilts to contact the other end 13b of the arm rod 13 and further pushes against the elastic force of the elastic body 14 connected to one end 13a of the arm rod 13. When the lower arm 16 is continuously tilted toward the vertically lower side, the other end 13 b of the arm rod 13 is pushed down by the push-down arm 16. That is, the other end 13 b of the arm rod 13 tilts vertically downward with the rotation shaft 12 as a base axis. At this time, the power generated in the arm rod 13 is transmitted to the second shaft 9 via the connecting portion 17, the second shaft 9 is rotated, and the locking tool 11 is rotated along with the rotation of the second shaft 9. Further, the locking arm 11a integrated therewith tilts so that the second shaft 9 jumps up to the base shaft, so that the locking structure of the locking arm 11a and the front container part 2a is released, and the front container part 2a is self-weighted. As a result, the second pivot 4 is tilted about the base axis, and the front container portion 2a is opened.
The procedure for opening the front container 2a will be described in detail later with reference to the drawings.

Returning to the description of the push-down arm 16 and the arm rod 13 again, the end of the push-down arm 16 on the side not connected to the first shaft 7 is made a smooth curved surface, whereby the arm rod by the push-down arm 16 is provided. The pressing operation of 13 can be made smooth (see FIG. 1).
Further, a recess 13c for locking the push-down arm 16 when the push-down arm 16 tilts and contacts the arm rod 13 may be formed (see FIG. 1). The recess 13 c can be used when the roll paper 27 is cut using the paper cutting mechanism 8. Details thereof will be described later.
Furthermore, a moving roller 16a may be provided at the end of the pressing arm 16 on the side not connected to the first shaft 7. In this case, when the power transmission plate 17b of the arm rod 13 is pushed down by the push-down arm 16, the movement of the push-down arm 16 can be made smooth (see FIG. 1).

In the roll paper holder 1A according to the first embodiment, the second roller 24 for receiving the roll paper 27 and feeding it out of the container part 2 is provided in the vicinity of the roll paper lead-out part 23 of the front container part 2a. The roll paper 27 led out from the container portion 2 together with the paper retaining roller 10 held by the locking arm 11a of the locking tool 11 may be configured to be lightly clamped (see FIG. 2).
In this case, since the load is applied by the paper retaining roller 10 and the roll paper 27 when the roll paper 27 is pulled out, unnecessary roll paper 27 can be prevented from being pulled out. The paper retaining roller 10 and the second roller 24 are not necessarily provided.
Further, a stopper 25 is provided on the side surface of the front container portion 2a in parallel with the roll paper lead-out portion 23. When the tilt plate 22 of the paper cutting mechanism 8 tilts with the first pivot 20 as the base axis, the tilt plate 22 is provided. The front container portion 2a is received and locked by the stopper 25 (see FIG. 2). A cushion material 26 may be provided on the stopper 25.
The stopper 25 cooperates with the tilting plate 22 at the time of cutting the roll paper 27 to stop pulling out the roll paper 27. By providing the cushion material 26, the stopper 25 prevents the roll paper 27 from slipping. Can be exhibited more effectively. Details of the function of the stopper 25 will be described later.

  Furthermore, in the roll paper holder 1A according to the first embodiment, when the arm rod 13 is urged by the elastic body 14, the arm rod 13 on the side plate 6a is maintained in order to keep the arm rod 13 substantially horizontal. A braking pin 15 may be provided on the track (see FIG. 1). By providing the brake pin 15, the arm rod 13 is prevented from rotating in the counterclockwise direction in a state where the push-down arm 16 does not act on the arm rod 13, and the second portion is connected via the connecting portion 17. Transmission of power to the shaft 9 can be suppressed. As a result, the paper holding roller 10 and the second roller 24 hold the roll paper 27 so that the roll paper 27 does not sag when the roll paper 27 is pulled out, while preventing the smooth roll paper 27 from being pulled out. The roll paper 27 can be held.

Next, a procedure for cutting the roll paper 27 by the roll paper holder 1A according to the first embodiment will be described in detail with reference to FIGS.
4 and 5 are cross-sectional views showing the operation of the roll paper holder according to the first embodiment of the present invention. The same parts as those described in FIGS. 1 to 3 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 3, in the state before pulling out the roll paper 27, the end of the roll paper 27 slightly protrudes from the lower end 22b of the tilting plate 22 of the paper cutting mechanism 8 suspended vertically by its own weight. In this way, it is led out from the container part 2 and the knob 28 is formed (step S10).

Then, from the state of the previous step S10, when the user picks up the picking allowance 28 with the fingertip and pulls out the roll paper 27 vertically downward, the tilting plate 22 of the roll paper 27 is removed as shown in FIG. The first pivot 20 is pushed up by the upper surface and tilted about the first pivot 20, and the support plate 19 is pushed up when the tilting plate 22 is pushed up (the first shaft 7 is pushed up to the base) (step S 11).
In step S <b> 11, a load is applied to the roll paper 27 led out from the roll paper lead-out unit 23 due to contact with the tilting plate 22 in addition to contact with the paper holding roller 10 and the second roller 24. Therefore, there is no fear that the roll paper 27 will be pulled out more than necessary, and the necessary amount can be pulled out without waste.

After this step S11, in order to cut the roll paper 27, from the state shown in FIG. 4, as shown in FIG. As a result, the tilting plate 22 tilts so that the lower end portion 22b jumps up with the first pivot 20 as the base shaft, and with this operation, the upper end portion 22a of the tilting plate 22 is locked by the stopper 25 and pulled out. The inner roll paper 27 piece is sandwiched between the stopper 25 and the upper end portion 22a of the tilting plate 22, and the drawing out of the roll paper 27 is temporarily stopped (step S12).
In step S12, as the tilting plate 22 tilts, the support plate 19 connected to the tilting plate 22 also tilts with the first shaft 7 as the base shaft, and as the first shaft 7 rotates, the first shaft 7, the push arm 16 fixed to the end of the side plate 6 a is tilted, and the tip of the push arm 16 is temporarily fitted into the recess 13 c formed on the arm rod 13. Can be prevented from tilting. Thereby, the force pulling up the roll paper 27 is used only for tilting of the tilting plate 22, and as a result, the upper end portion 22 a of the tilting plate 22 can be reliably locked to the stopper 25.

Further, after the previous step S12, the pulling piece of the roll paper 27 is pulled up vertically from the state shown in FIG. The roll paper 27 can be cut at the lower end 22b (step S13).
The roll paper 27 may be easily cut by providing fine serrated irregularities at the corners on the container part 2 side of the lower end part 22b of the tilting plate 22.
