  In addition, the protective cover includes a first wall portion and a second wall portion sandwiching the paper support shaft between each other with respect to the first direction at the facing position, and a second perpendicular to the first direction at the facing position. And a third wall portion disposed on one side of the paper support shaft with respect to the direction, and the support body has the paper support shaft with respect to a third direction orthogonal to both the first direction and the second direction. An inner wall defined by the first wall portion to the fourth wall portion when the protective cover is in the facing position. It is preferable to use a roll paper holder disposed in the space.

  Further, the protective cover is supported by the support so as to be rotatable with respect to a rotation axis along the first direction, and the rotation axis is in the second direction when the protection cover is in the facing position. With respect to the paper support shaft, the roll paper holder is disposed at a position opposite to the third wall portion and separated from the fourth wall portion with respect to the third direction. It is preferable.

  Further, the restricting means is in contact with one member of the protective cover and the support, and restricts the relative movement of the one member with respect to the other member, and is separated from the restricting position. A regulating member supported by the other member so as to be movable between a releasing position to be released and an urging means for urging the regulating member toward the regulating position. And an inclined surface that is an inclined surface with respect to a direction from the release position toward the restriction position, and the inclined surface is moved when the protective cover moves from the non-opposing position to the opposing position. A roll paper holder that moves the regulating member toward the release position against the urging force of the urging means while being in contact with a part of the urging means, and is separated from the inclined surface before reaching the opposing position Toss It is preferable.

  Further, the pair of paper support shafts are arranged in the first direction, the tip portions of the pair of paper support shafts are arranged on opposite sides with respect to the first direction, and the first wall portion is The roll paper holder is disposed at a position facing the tip portion of one of the paper support shafts, and the second wall portion is disposed at a position facing the tip portion of the other paper support shaft. It is preferable to use a tool.

  By disposing the protective cover at the facing position, the protective cover directly regulates the movement of the roll paper from the paper support shaft. Therefore, the roll paper can be easily removed without disposing the roll paper in an unusable state.

It is a front view of the roll paper holder which concerns on one Embodiment of this invention. It is a rear view of the roll paper holder of FIG. It is a top view of the roll paper holder of FIG. It is a bottom view of the roll paper holder of FIG. It is a right view of the roll paper holder of FIG. FIG. 6 is a view corresponding to FIG. 5 in a state where the protective cover 3 is opened. (A) is a front view of the locking mechanism 50, (b) is a plan view, and (c) and (d) are cross-sectional views on the right side.

  A roll paper holder 1 according to an embodiment of the present invention will be described with reference to FIGS. In addition, since the roll paper holder 1 is an example of two right and left roll paper holders in FIG. 1 and has a bilaterally symmetric configuration, the following mainly describes the configuration of the right half in FIG. The description of the left half configuration will be omitted as appropriate.

  The roll paper holder 1 has a main body 2 (support body) that supports roll paper such as toilet paper and a protective cover 3, and has a substantially rectangular parallelepiped shape as a whole. The main body 2 has an L-shaped schematic shape in a side view (see FIG. 6), a back plate 21 (fourth wall), a bottom plate 22, a front lower plate 23, a right lower plate 24, and a left lower plate. 25. A through hole 21 a is formed in the back plate 21. When the main body 2 is fixed to a building wall or the like, the main body 2 is fixed by screws or the like through the through holes 21a. The through-holes 21a include those extending along the horizontal direction and those extending along the vertical direction. Thereby, when fixing with a screw, it is easy to adjust a position to a horizontal direction and a perpendicular direction, respectively. Here, the left-right direction (horizontal direction) in the front view of FIG. 1 is referred to as a first direction, the up-down direction (vertical direction) is referred to as a second direction, and the front-rear direction is referred to as a third direction.

  A through hole 22a having a rectangular planar shape is formed in the bottom plate 22 (see FIG. 4). The front lower plate 23 is formed by bending the front end portion of the bottom plate 22 vertically upward. The front lower plate 23 is adjusted to a height that does not interfere with a roll paper R supported by a paper support shaft 28 described later (see FIGS. 1 and 6). The right lower plate 24 and the left lower plate 25 are formed by bending the right end portion and the left end portion of the bottom plate 22 vertically upward. In a side view, the upper end edge 24a extends upward from the front end toward the rear end while curving in a downward convex shape. The upper edge 24a is adjusted so as not to interfere when the roll paper R is attached to and detached from the paper support shaft 28 (see FIG. 6).

  The main body 2 has fixing plates 26 and 27 and a lock mechanism 50 (regulating means). The fixed plates 26 and 27 are configured by bending the end portions of the flat plate into an L shape. The fixing plates 26 and 27 are fixed back to back at substantially the center position in the horizontal and vertical directions on the front surface of the back plate 21. In the fixing plates 26 and 27, a pair of paper support shafts 28 are fixed symmetrically at one end opposite to the back plate 21. The paper support shaft 28 includes a cylindrical portion 28a fixed to the fixing plates 26 and 27, and a distal end portion 28b fixed to the distal end of the cylindrical portion 28a. The cylindrical portion 28a extends horizontally from the fixed plates 26 and 27 in the left-right direction in FIG. The distal end portion 28b extends further from the distal end of the cylindrical portion 28a to the left and right. The diameter of the cylindrical portion 28a is adjusted so that the core of the roll paper R can pass through (see FIGS. 5 and 6). While the screw shaft 27a is fixed to the fixed plate 27, a through hole is formed also on the cylindrical portion 28a side, and the screw is cut on the inner surface so as to be fitted to the screw shaft 27a. The paper support shaft 28 is fixed to the fixing plates 26 and 27 by these screw structures. By using this screw, the paper support shaft 28 and the support shaft having a different shaft diameter can be used interchangeably according to the type of roll paper having a different inner diameter.

  The protective cover 3 includes a top plate 31 (third wall portion), a right side plate 32 (first wall portion), a left side plate 33 (second wall portion), and a rear upper plate 34, and as a whole, the front-rear direction ( (Third direction) and a box-like schematic shape opened downward. The rear upper plate 34 is formed by bending the rear end of the top plate 31 vertically downward, and the lower end thereof substantially coincides with the upper end of the rear plate 21 of the main body 2. The protective cover 3 is supported at the front end of the right lower plate 24 and the front end of the left lower plate 25 of the main body 2 by a fastener 41 so as to be rotatable in the direction B of FIG. The position of the fastener 41 is the position on the opposite side of the top plate 31 (third wall) with respect to the support axis of the roll paper in the vertical direction (second direction), and in the front-rear direction (third direction). ) Is arranged at a position isolated from the back plate 21 (fourth wall). Preferably, the position of the fastener 41 interferes with the roll paper in the state supported by the paper support shaft in the vertical direction (second direction) as shown in FIGS. 5 and 6 with respect to the paper support shaft. In order to avoid this, it is preferable that the positions are appropriately spaced on the lower side of the roll paper, and the positions in the vicinity of the axis center of the paper support shaft in the front-rear direction (third direction).

  Thereby, the protective cover 3 can be displaced between the position of FIG. 5 (a state in which the protective cover 3 is attached) and the position of FIG. 6 (a state in which the protective cover 3 is opened). 5, the right side plate 32 (first wall portion) and the left side plate 33 (second wall portion) of the protective cover 3 are close to the front end portion 28 b of the paper support shaft 28. opposite. In this state, the roll paper R supported by the paper support shaft 28 cannot be removed in the axial direction by these wall portions. On the other hand, in the open state position (non-opposing position) of FIG. 6, the right side plate 32 and the left side plate 33 of the protective cover 3 are completely separated from the front end portion 28 b of the paper support shaft 28. In this state, the roll paper R can be freely attached and detached along the left-right direction (first direction) from one side (the front end 28 b side) of the paper support shaft 28. Since the protective cover 3 is supported by a fastener 41 at the bottom of the main body 2, the protective cover 3 hangs downward from the main body 2. The degree of proximity between the right side plate 32 and the left side plate 33 and the tip portion 28b is set such that the roll paper R cannot be removed from the paper support shaft 28 when the protective cover 3 is in the position shown in FIG.

  The protective cover 3 is provided with a pair of paper cutters 35 arranged in the left-right direction. A support pipe 36 is supported by fasteners 42 near the upper ends of the right side plate 32 and the left side plate 33. The support pipe 36 has a small diameter portion 36a having a small diameter and a large diameter portion 36b having a large diameter. On the other hand, at the rear end portion of the paper cutter 35, a support portion 35a configured by bending a part of both ends in the left-right direction is provided. A circular through hole is formed in the support portion 35a, and the paper cutter 35 is rotatably supported in the direction A in FIG. 5 by passing the through hole through the narrow diameter portion 36a of the support pipe 36. ing. The movement of the paper cutter 35 in the left-right direction is regulated by the large diameter portion 36b.

  When the roll paper R is not supported by the paper support shaft 28, the paper cutter 35 is held in contact with the paper support shaft 28 as shown in FIG. In this state, the paper cutter 35 extends downward from the rear end (upper end) while curving forward. When the roll paper is supported by the paper support shaft 28, the tip of the paper cutter 35 comes into contact with the surface of the roll paper as shown by a two-dot chain line in FIG. Further, the paper cutter 35 is provided with a contact portion of the paper cutter so that the upward movement of the paper cutter 35 is restricted at a position appropriately separated from the outer peripheral surface of the roll paper. The upper limit of the paper cutter is the position indicated by the dotted line in FIG. Therefore, since the paper cutter 35 is always located obliquely above the front of the roll paper, the paper cutter 35 serves to protect the roll paper from the obliquely upper front and prevent the roll paper R from being pulled out.

  Next, the restriction means for the protective cover 3 will be described. As shown in FIG. 5, the restricted state (attached state) of the protective cover 3 is realized by coupling the lock mechanism 50 provided in the main body 2 and the combined body 60 provided in the protective cover 3. As shown in FIG. 5, the united body 60 is provided on the back plate 21 side facing the inner side of the top plate 31 of the protective cover 3, and the lock mechanism 50 has an appropriate gap on the lower side part of the united body 60. It is fixed to the back plate 21 at a position where both can be coupled.

  An example of the lock mechanism 50 will be described with reference to FIG. (A) is a front view, (b) is a plan view, and (c) and (d) are cross-sectional views on the right side. The lock mechanism 50 includes a lock pin 52 (regulating member), a box 53, and a spring 54 (biasing means). The lock pin 52 is parallel to the axial direction and an inclined surface 52b whose upper part is inclined with respect to the axial direction. It consists of a cylindrical part 52a having a rotation restricting surface 52c, a core bar 56a fixed to the lower end of the cylindrical part, and a washer 56b. The box 53 that accommodates the lock pin 52 includes a main body 53a having a cylindrical hole for sliding the lock pin 52 up and down, a rotation restricting body 53b that slides the rotation restricting surface 52c up and down to restrict rotation, and a core rod 56a. Is formed in the bottom plate 53c, and a space for accommodating the spring 54 that urges the lock pin 52 upward to the limit position by the washer 56b is provided below the lock pin 52.

  7C and 7D, the coupling between the lock mechanism 50 and the combined body 60 will be described. As shown in FIG. 6, when the protective cover 3 moves from the open state to the attached state (restricted state) (direction B1), the combined body 60 moves in the direction of the arrow as shown in FIG. 7C. Then, the lower end portion of the combined body 60 is pressed down while abutting against the inclined surface 52b, and after getting over the lock pin 52, the lock pin 52 is stored in the space provided in the combined body 60, The state in which the tip portion is in contact with the axially rear surface of the lock pin 52 and cannot be moved backward is a locked state.

  To release the locked state, as shown in (d), the auxiliary member 55 connected to the lower end of the core rod 56a is pushed down against the spring 54 by an external force to eliminate the protrusion of the lock pin 52 from the box 53. The combined body 60 can move in the direction of the arrow, the lock is released, and the protective cover 3 can move in the open state (B2) shown in FIG. When the external force is removed, the lock pin 52 protrudes and returns to the initial state. As described above, since the lock mechanism 50 and the combined body 60 are configured inside the apparatus, a general user cannot operate the opening and closing of the protective cover 3.

  As shown in FIG. 1, the lock mechanism 50, which is a restricting means of the protective cover 3 in this apparatus, and the position of the combined body 60 are arranged in two sets on the left and right ends inside the apparatus, and the auxiliary member 55 is an L-shaped plate. However, the number of the restricting means in the present invention may be one or more, and the arrangement is not limited to this example. Further, the connection between the auxiliary member 55 and the core rod 56a may be configured to be detachable. Usually, the auxiliary member 55 can be removed from the core rod 56a so that only persons involved in management can operate it without permission.

  According to the present embodiment described above, the paper support shaft 28 is disposed in the internal space defined by the main body 2 and the protective cover 3 in the state of FIG. As a result, the roll paper supported by the paper support shaft 28 is protected by the wall portion from five directions, ie, up, down, left, right, and rear. Furthermore, the front opening can be expected to be protected by limiting the upward movement of the paper cutter 35. In the state of FIG. 1, the movement of the protective cover 3 is restricted by the lock mechanism 50, and it is not easy for anyone other than those involved in management to open the protective cover 3 and take out the roll paper. On the other hand, when the protective cover 3 is opened, it hangs below the main body 2 as shown in FIG. Therefore, it is not necessary to work while holding down the protective cover 3, and the work of attaching and detaching the roll paper is easy. Furthermore, since the through-hole is formed in the bottom plate 22 of the main body 2, paper dust falling from the roll paper is difficult to accumulate in the main body 2.

  Hereinafter, modifications of the present embodiment will be described. The roll paper holder 1 of the present embodiment has a wall portion mainly formed of a flat plate, but may have a wall portion with a curved surface. Moreover, although the boundary of wall parts (for example, the top plate 34 and the right side board 32) is comprised comparatively clearly, these boundaries are not especially clear, for example, you may form in R shape. Moreover, although the structure which accommodates two roll paper is employ | adopted, only one roll paper may be accommodated.
