Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a roll paper cutter that can cut roll paper such as toilet paper. [Background technology]
[0002] Generally, rolled paper such as toilet paper is held in a paper holder. When using the rolled paper, the user pulls out the required length of the leading end of the rolled paper from the paper holder, and then cuts off the leading end while holding down the rolled paper.
[0003] When using conventional roll paper, there was a problem that when pulling out the roll paper, the tip of the roll was in close contact with the roll paper, making it difficult to grasp. There was also the problem that holding down the roll paper to cut it was difficult for people with disabilities, the elderly, and small children. Furthermore, while there have been many calls recently for preventing infection, toilet paper in public places, which is an example of roll paper, has the problem that it is touched by an unspecified number of people with hands that may be contaminated with viruses or bacteria, thereby contributing to the spread of infection.
[0004] For example, regarding the spread of infectious diseases, there was a news report about an elementary school where more than half of the students were infected with norovirus, leading to the school's closure. At that school, teachers instructed students to fold toilet paper into a triangle after using the toilet as a matter of etiquette, and the students obediently followed the instructions. As a result, an infected person touched the toilet paper with their contaminated hands, and the next person touched the contaminated toilet paper, repeatedly, leading to the spread of infection. While toilet paper in public restrooms is likely to be touched by an unspecified number of people, it is an important issue in preventing the spread of infection, even though it is easily overlooked.
[0005] To solve the above problem, a paper holder has been developed that is equipped with a paper cutter (horizontal bar with a blade) below the paper holder so that the rolled paper can be cut without touching the rolled paper (see, for example, Patent Document 1). Specifically, the paper holder in Patent Document 1 includes a paper holder main body to which the rolled paper is attached, an arm extending downward from the paper holder main body, and a horizontal bar with a blade extending horizontally from the lower end of the arm below the paper holder main body. The horizontal bar with a blade is equipped with a blade that can cut the rolled paper, and is attached to the paper holder so that it can cut rolled paper with its tip hanging down.

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present disclosure will now be described with reference to the accompanying drawings. A roll paper cutter according to the present disclosure is a cutter used to cut roll paper.
[0020] A roll paper cutter 1 according to this embodiment will be described with reference to Figures 1 to 7. Figure 1 is a perspective view showing the roll paper cutter 1 according to this embodiment in use. Figure 2 is a front view of the roll paper cutter according to this embodiment. Figure 3 is a rear view of the roll paper cutter according to this embodiment. Figure 4 is a left side view of the roll paper cutter according to this embodiment. Figure 5 is a right side view of the roll paper cutter according to this embodiment. Figure 6 is a plan view of the roll paper cutter according to this embodiment. Figure 7 is a bottom view of the roll paper cutter according to this embodiment.
[0021] In this embodiment, the rolled paper P is toilet paper, and is attached to a paper holder H installed on a wall W of a house or the like with the axis of the rolled paper P oriented horizontally. The rolled paper cutter 1 is attached to the wall W of a house or the like below the paper holder H for the rolled paper P. The rolled paper P is not limited to toilet paper, and may be paper wound into a roll, such as kitchen paper. The rolled paper P is not limited to being attached with the axis oriented horizontally, and can be attached with the axis oriented in any direction, such as vertically. When the rolled paper P is attached with the axis oriented vertically, the rolled paper cutter 1 is attached to the wall W to the side of the paper holder H for the rolled paper P. The paper holder H and the rolled paper cutter 1 may be attached not only to the wall W of a house or the like, but also to the wall W of household goods such as a refrigerator. In the following, when the roll paper cutter 1 is attached to a wall W and used as shown in Figure 1, the vertical direction is defined as the up-down direction, the direction along the wall W is defined as the left-right direction, and the direction perpendicular to the up-down and left-right directions and perpendicular to the wall W is defined as the front-rear direction. The roll paper cutter may be attached directly to the paper holder H. The roll paper cutter may also be attached to a handrail or the like near the paper holder H.
[0022] The roll paper cutter 1 includes a cutter body 10 and a mounting fixture 20 for mounting the cutter body 10 to a wall surface W.
[0023] The cutter body 10 cuts the rolled paper P. The cutter body 10 has a main body portion 11 that extends in the axial direction (left-right direction) of the rolled paper P, and a connecting portion 12 that extends in the radial direction (front-back direction) of the rolled paper P and connects the main body portion 11 to the attachment tool 20.
[0024] The main body 11 and the connecting portion 12 are formed from a rod-shaped material having a predetermined width. Here, width refers to the length in the front-rear direction for the main body 11 and the length in the left-right direction for the connecting portion 12. The connecting portion 12 has an attachment 20 attached to one end (rear end) thereof and the main body 11 attached to the other end (front end). The main body 11 has a fixed end 111 and a tip end 112 that is a free end, and the fixed end 111 is connected to the connecting portion 12. In this case, the cutter body 10 has a substantially L-shape in a plan view (see FIG. 6 ). The shape of the cutter body 10 in a plan view includes not only a shape in which the main body 11 and the connecting portion 12 are connected at a sharp corner, but also a shape in which the main body 11 and the connecting portion 12 are connected at a curved corner, and a shape in which the main body 11 and the connecting portion 12 are connected in a substantially arched shape. Even when the planar shape of the cutter body 10 has curved corners or is roughly arched, the part that is roughly perpendicular to the wall surface W and that is interpreted as extending in the radial direction of the rolled paper P is the connecting part 12, and the part beyond the connecting part 12 is the main body part 11.
[0025] The main body 11 has a length (left-right length) that is longer than the axial length of the rolled paper P. The connecting portion 12 has a length (front-rear length) that is longer than the diameter of a new rolled paper P. As a result, when the cutter body 10 is attached to the wall surface W below the paper holder H, the new rolled paper P hanging down from the paper holder H is positioned inside the approximate L-shape of the main body 11.
[0026] 6, the main body 11 is attached to the connecting part 12 at an angle forward from the connecting part 12 in a plan view so that when attached to a wall W, the distance from the wall W increases from the fixed end 111 toward the tip 112. In addition, the tip 112 of the main body 11 is curved toward the wall W (rear side). This makes it easy to insert the rolled paper P from the tip 112 of the main body 11 between the cutter body 10 and the wall W, and also makes it difficult for the rolled paper P to slip out from between the cutter body 10 and the wall W.
[0027] The cutter body 10 has a saw-tooth blade 13. The blade 13 is provided over the main body 11 and at least a portion of the connecting portion 12. The blade 13 is provided on the lower surfaces of the main body 11 and the connecting portion 12 so as to protrude downward, or so as to protrude downward and toward the inside of the approximately L-shape. The blade 13 may be provided integrally with the cutter body 10, or may be provided detachably with respect to the cutter body 10.
[0028] Each blade constituting the saw-tooth blade portion 13 has any known shape, such as a straight, V-shaped, or arched shape. The blade portion 13 can also have any known shape, such as a saw-tooth shape with blades of the same size arranged side by side, a saw-tooth shape with alternating larger and smaller blades, or a saw-tooth shape with blades that gradually change size toward one side. That is, the blade portion 13 may have any shape that can consistently cut the rolled paper P, whose diameter changes with use. However, because the blade portion 13 may come into contact with a human hand, a blade that can cut the rolled paper P but is not too sharp and can be used safely is preferred. The number of protrusions on the blade portion 13 is not particularly limited, but is, for example, 30 to 80, and preferably 50 to 75. The narrower the pitch of the protrusions on the blade portion and the more protrusions there are, the cleaner the cut portion of the rolled paper will be after cutting.
[0029] The inner surfaces of the approximately L-shape of the main body 11 and the connecting part 12 are preferably flat. The blade part 13 is preferably provided on the wall surface W side of the main body 11 and the connecting part 12, that is, on the inner side of the approximately L-shape, protruding downward. This makes it easier for the rolled paper P to come into contact with the blade part 13, and the rolled paper P can be cut easily.
[0030] The mounting fixture 20 is used to mount the cutter body 10 to a wall surface W. In this embodiment, the mounting fixture 20 has a mounting fixture main body 21 attached to the connecting portion 12, and a cover body 22 that covers the mounting fixture main body 21.
[0031] The fixture body 21 has a plate shape and is provided with mounting means 211 for mounting the roll paper cutter 1 to the wall surface W. As shown in FIG. 3 , in this embodiment, the mounting means 211 is provided with mounting holes 211 for screwing or nailing the roll paper cutter 1 to the wall surface W. The fixture body 21 may be integral with the connecting portion 12 or may be a separate component. The mounting means 211 may be any member that can mount the roll paper cutter 1 to the wall surface W without causing it to fall off, and may be any member other than screws and nails, such as adhesives, suction cups, or magnets. In this case, if a mounting hole is not provided and a suction cup or magnet is used, the suction cup or magnet is attached to the back surface (rear surface) of the fixture body 21.
[0032] The cover body 22 covers the attachment body 21 and improves the appearance of the attachment portion of the roll paper cutter 1 attached to the wall surface W. In this embodiment, the cover body 22 is clover-shaped. The cover body 22 has a through-hole (attachment hole) 221 in the center for inserting the cutter body 10, and a storage section 222 capable of storing the attachment body 21 is provided on the back surface (rear surface). The through-hole 221 has a size and shape that allows the cutter body 10 to be inserted and that can cover the vicinity of the connection portion of the connecting portion 12 with the attachment body 21. The storage section 222 has a size and shape that allows the attachment body 21 to be stored without sliding or rotating. Note that the cover body 22 is not limited to a clover-shaped shape and can be any shape with excellent design, such as a cat or a flower.
[0033] As shown in Figure 3, the fixture main body 21 and the cover body 22 are provided with an engaging protrusion 23 on one side and an engaging recess 24 on the other side that can engage with the engaging protrusion 23. In this embodiment, the fixture main body 21 is provided with the engaging protrusion 23, and the cover body 22 is provided with the engaging recess 24. The engaging protrusion 23 and the engaging recess 24 are located in a position where, when the fixture 20 is attached to the wall surface W with the cover body 22 engaged and oriented appropriately, the main body 11 is inclined relative to a horizontal plane parallel to the axis of the rolled paper P. In other words, the fixture main body and the cover body are designed to be oriented appropriately, allowing the main body 11 to be inclined at a predetermined angle relative to a horizontal plane parallel to the axis of the rolled paper P.
[0034] The cutter body 10 and the attachment 20 are made of, for example, resin, metal, ceramic, or wood. When the rolled paper P is applied to the rolled paper cutter 1 to cut it, a force is generated in the cutter body 10 in a direction pushing up the blade portion 13, and a force is generated in the attachment 20 in a direction moving away from the wall surface W. Therefore, the cutter body 10 is formed with enough strength to prevent bending and plastic deformation even when a force pushing up the blade portion 13 is applied. In other words, the main body 11 and the connecting portion 12 have a width that prevents bending and plastic deformation even when a force pushing up the blade portion 13 is applied. When the main body 11 and the connecting portion 12 are made of resin, ribs are provided inside the body 11 and the connecting portion 12 to provide enough strength to prevent bending and plastic deformation even when a force pushing up the blade portion 13 is applied. A rib structure is preferable in terms of preventing warping, bending, increasing strength and rigidity, and improving fluidity (filling efficiency). The mounting fixture 20 also has an attachment means that allows the roll paper cutter 1 to be attached with enough strength so that it will not separate from the wall W even when a force is applied in the direction away from the wall W. A rib cover can be provided to cover the rib structure. The rib cover can be removed to clean the inside of the ribs depending on the situation of use, hygiene, etc. The roll paper cutter of the present disclosure can be manufactured using conventional molding methods such as injection molding and extrusion molding, or using a 3D printer.
[0035] As shown in FIG. 1 , the roll paper cutter 1 is attached to a wall surface W below a paper holder H for use. Specifically, the attachment body 21 is attached to the wall surface W. At this time, the attachment body 21 is attached to the wall surface W so that the engagement protrusion 23 is in a predetermined position. Because the attachment body 21 is attached to the connecting portion 12 and is integrated with the cutter body 10, the cutter body 10 is also attached to the wall surface W. In this state, the cutter body 10 is inserted into the through-hole 221 of the cover body 22, and the attachment body 21 is accommodated in the accommodation portion 222 of the cover body 22, thereby attaching the cover body 22 to the attachment body 21. At this time, the engagement recess 24 engages with the engagement protrusion 23, so that the cover body 22 faces in an appropriate position. In other words, the predetermined position of the engagement protrusion 23 is the position where the cover body 22 faces in an appropriate position when the engagement recess 24 and the engagement protrusion 23 engage. When attached in this manner, the main body 11 is attached at a slight upward incline relative to the horizontal plane. The length of the connecting portion is not particularly limited, but is, for example, about 1 cm to 15 cm, preferably about 3 cm to 10 cm, and more preferably about 5 cm to 8 cm. The cross-sectional shape of the connecting portion is not particularly limited, and examples thereof include a circle, a substantially circle, a square, and a substantially square. The thickness (diameter) of the connecting part is not particularly limited, but is, for example, about 1 cm to 4 cm, and preferably about 1.5 to 3 cm. The connecting part on the side that is attached to the wall surface is preferably thicker than the connecting part closer to the cutter body. Part of the connecting part can be made flat. The flat surface in the connecting part is preferably on the tip side of the cutter body. The flat part makes it easier for the cutter (blade part) to come into contact with the rolled paper, which has the effect of improving sharpness.
[0036] The roll paper cutter can be attached to a wall by inserting a screw into the mounting hole. This secures the roll paper cutter to the wall. The roll paper cutter can also be attached to the wall with double-sided tape, adhesive, etc.
[0037] The length of the cutter body having a saw-tooth blade is not particularly limited, but is, for example, about 10 cm to 20 cm, and preferably about 1 cm to 15 cm. The cross-sectional shape of the cutter body is not particularly limited, and examples thereof include a circle, a nearly circle, a square, and a nearly square. The thickness (diameter) of the cutter body is not particularly limited, but is, for example, about 0.5 cm to 4 cm, and preferably about 1 to 3 cm. The thickness of the cutter body preferably tapers from the fixed part to the tip. A part of the cutter body can be made flat. The flat part of the cutter body is preferably on the wall side.
[0038] The roll paper cutter 1 is preferably attached approximately 10 to 20 cm below the paper holder. This ensures that the leading edge Pe of the roll paper P always protrudes 10 to 20 cm, making it easier for the user of the roll paper P to grasp the leading edge Pe of the roll paper P.
[0039] Furthermore, the roll paper cutter of the present invention has the effect of making it easy to cut roll paper regardless of which hand the user uses, whether it is the right hand, left hand, dominant hand, non-dominant hand, etc. The roll paper cutter of the present invention can be used with either one hand or both hands. [Example]
[0040] Hereinafter, the present disclosure will be described in further detail with reference to examples and comparative examples. It should be noted that the present disclosure is not limited in any way by the following examples.
[0041] Example 1 Example 1 (Prototype 7) used the toilet paper cutter of Prototype 7 shown in Figures 2 to 7. Specifically, (1) the tip 112 of the main body 11 of the toilet paper cutter was slightly curved inward (toward the wall). (2) The attachment part 20 had an attachment part main body 21 and a cover body 22, and the attachment part main body 21 was provided with two engaging protrusions (projections) 23. The thickness (diameter) of the fixed end 111 was approximately 15 mm, the thickness (diameter) of the tip 112 was approximately 11 mm, the length of the connecting portion 12 was approximately 65 mm, and the length of the main body 11 was approximately 140 mm. The size (width) of the cover body 22 was approximately 60 mm, and its thickness was approximately 8 mm. The diameter of the attachment main body 21 was approximately 40 mm, and its thickness was approximately 3 mm. The blade portion 13 had approximately 69 protrusions. The main body 11 of the toilet paper cutter was tilted upward approximately 16 degrees from the horizontal. Furthermore, the distance from the wall surface to the main body 11 of the toilet paper cutter increased from the fixed end 111 toward the tip 112, and the main body 11 was tilted approximately 13 degrees relative to the wall surface.
[0042] Comparative Example 1 Comparative Example 1 (Prototype 1) used the toilet paper cutter of Prototype 1 shown in Figure 9. Specifically, (1) the cutter body 10 was parallel to the wall surface. (2) The blade portion 13 was provided only on the cutter body 10. Note that in Comparative Example 1 (Prototype 1), the attachment 20 only has the attachment portion main body 21 and does not have the cover body 22. The thickness (diameter) of the fixed end portion 111 was approximately 15 mm, the thickness (diameter) of the tip portion 112 was approximately 11 mm, the length of the connecting portion 12 was approximately 60 mm, and the length of the main body portion 11 was approximately 137 mm. The thickness (diameter) of the attachment main body 21 was approximately 37 mm. The blade portion 13 had approximately 28 protrusions.
[0043] Example 2 Example 2 (prototype 2) used the toilet paper cutter of prototype 2 shown in Figure 10. Specifically, (1) the cutter body 10 was made round and thick to make it less likely to break. (2) The position of the blade 13 of the cutter body 10 was moved to the center of the bottom or closer to the toilet paper, and better positions were considered. (3) To prevent the toilet paper from slipping, a non-slip surface was created on the tip 112 of the cutter body 10. (4) To improve sharpness, the blade 13 was extended close to the attachment part 20. (5) Various locations for the blade 13 (for example, the lower side or upper side of the cutter body 10) were tested. Note that in Example 2 (prototype 2), the attachment 20 only has the attachment part main body 21 and does not have a cover body 22. The thickness (diameter) of the fixed end 111 was approximately 23 mm, the thickness (diameter) of the tip 112 was approximately 18 mm, the length of the connecting portion 12 was approximately 40 mm, and the length of the main body 11 was approximately 150 mm. The size of the mounting body 21 was approximately 70 mm (top and bottom) x approximately 75 mm (left and right), and its thickness was approximately 5 mm. The blade portion 13 had approximately 35 protrusions.
[0044] Example 3 For Example 3 (prototype 3), the toilet paper cutter of prototype 3 shown in Figure 11 was used. The toilet paper cutter had a (distance from the wall surface side of the fixed end to the attachment (length of the connecting part)) of approximately 70 mm, and b (distance from the wall to the tip (distance from the wall to the tip on the opposite side)) of approximately 110 mm (see Figure 12 (b)). Specifically, (1) a toilet paper cutter with a curved cutter body 10 was created to prevent the toilet paper from slipping. (2) The attachment part 20 was designed with a clover pattern. Note that in Example 3 (prototype 3), the attachment part 20 only has an attachment part body 21 and does not have a cover body 22. The thickness (diameter) of the fixed end 111 was approximately 18 mm, the thickness (diameter) of the tip 112 was approximately 15 mm, and the length of the main body 11 was approximately 160 mm (the straight line length from the attachment part (inside) to the tip). The blade part 13 had approximately 43 convex parts.
[0045] Example 4 Example 4 (prototype 4) used the toilet paper cutter of prototype 4 shown in Figure 12 (a is approximately 50 mm, b is approximately 95 mm). Specifically, (1) to make it easier to insert toilet paper, the shape of the cutter body 10 was changed from an L-shape perpendicular to the wall surface to a shape where the tip 112 is slightly wider on the side opposite the wall surface. (2) The clover pattern design of the attachment part 20 was made undulating. Note that in Example 4 (prototype 4), the attachment tool 20 only has the attachment part main body 21 and does not have a cover body 22. The thickness (diameter) of the fixed end 111 was about 15 mm, the thickness (diameter) of the tip 112 was about 12 mm, the length of the connecting portion 12 was about 65 mm, and the length of the main body 11 was about 140 mm. The blade portion 13 had about 47 protrusions.
[0046] Example 5 Example 5 (prototype 5) used the toilet paper cutter of prototype 4 shown in Figure 13. Specifically, (1) the attachment 20, cutter body 10, etc. were all made smaller while taking strength into consideration. (2) The cutter body 10 was turned downwards and upwards to test how well it cut toilet paper. (3) The back surface and wall side of the cutter body 10 were cut flat. (4) For safety reasons, the blade of the blade portion 13 was adjusted to be sharp enough to cut toilet paper. Note that in Example 5 (prototype 5), the attachment 20 only has the attachment body 21 and does not have a cover body 22. The thickness (diameter) of the fixed end 111 was approximately 17 mm, the thickness (diameter) of the tip 112 was approximately 12 mm, and the length of the connecting portion 12 was approximately 50 mm. The blade portion 13 had approximately 38 convex portions (the length of the main body 11 was approximately 147 mm), or the blade portion 13 had approximately 44 convex portions (the length of the main body 11 was approximately 163 mm).
[0047] Example 6 Example 6 (prototype 6) was similar to the prototype toilet paper cutter shown in Figures 2 to 7, but did not have an engaging protrusion (projection) 23 on the attachment body 21. Specifically, (1) the tip 112 of the body 11 of the toilet paper cutter was slightly curved inward (toward the wall).
[0048] <Test example 1 (sharpness)> Six evaluators cut toilet paper 10 times with one hand using the toilet paper cutters of Examples 1 to 6 and Comparative Example 1. They cut five times with their right hand and five times with their left hand. The number of times they were able to cut cleanly was counted. Cleanly refers to the state of the cut surface of the toilet paper after cutting. Sharpness can also be said to be the ease of cutting. 5-star rating: 5:10 clean cuts. 4:9 times I was able to cut it cleanly. 3: I was able to make 8 clean cuts. 2: I was able to cut it 7 times. I was able to cut it 1:6 times. The results are shown in Table 1.
[0049] <Test Example 2 (Stability)> Six evaluators used the toilet paper cutters of Examples 1 to 6 and Comparative Example 1 to evaluate the stability (sense of stability) of the toilet paper cutter after installation. 5-star rating: 5:Firmly and stably fixed. 4: Stable and fixed. 3: Somewhat weak depending on the type of wall. 2: Somewhat weak. 1: Weak. The results are shown in Table 1.
[0050] <Test Example 3 (Installability)> Six evaluators evaluated the ease of attachment of the toilet paper cutters of Examples 1 to 6 and Comparative Example 1 at the optimum attachment angle in a short time. 5-star rating: 5:Good. 4: Fairly good. 3: Normal. 2: Somewhat bad. 1: Bad. The results are shown in Table 1.
[0051] <Test Example 4 (Design)> The toilet paper cutters of Examples 1 to 6 and Comparative Example 1 were evaluated for design by six evaluators. 5-star rating: 5:Good. 4: Fairly good. 3: Normal. 2: Somewhat bad. 1: Bad. The results are shown in Table 1.
[0052] <Overall rating> The scores for Test Examples 1 to 4 were totaled for an overall evaluation. The results are shown in Table 1.
[0053] [Table 1]
[0054] As described above, the roll paper cutter 1 of the present disclosure has a blade portion 13 that extends from the main body portion 11 to at least a portion of the connecting portion 12. As a result, when cutting the roll paper P with one hand, even if the roll paper P moves toward the connecting portion 12, the blade portion 13 provided on the connecting portion 12 can easily cut the roll paper P. Furthermore, the leading end Pe of the roll paper P cut using the roll paper cutter 1 is slightly pulled out from the paper holder H because the roll paper cutter 1 is located below or to the side of the paper holder H. This makes it easy for anyone, including physically disabled people, the elderly, and young children, to grasp the leading end Pe of the roll paper P, and allows the roll paper P to be easily pulled out with one hand.
[0055] Furthermore, with conventional paper holders H, when cutting the rolled paper P, the leading edge Pe of the rolled paper P is hidden by the blade of the paper holder H, and so when pulling out the rolled paper P, it is necessary to lift the blade of the paper holder H or rotate the rolled paper P. This can lead to the spread of infection when someone infected with an infectious disease or carrying a virus or bacteria touches the paper holder H or the rolled paper P, and the next person touches the infected paper holder H or rolled paper P. However, with the rolled paper cutter 1 of the present disclosure, the leading edge Pe of the rolled paper P is located near the rolled paper cutter 1. This eliminates the need to accidentally touch the main body of the rolled paper P when cutting it. Furthermore, because the leading edge Pe of the rolled paper P is untouched by humans, there is no risk of viruses or bacteria adhering to it. This contributes to preventing the spread of infectious diseases.
[0056] Additionally, the roll paper cutter 1 of the present disclosure is attached to a wall W below or to the side of the paper holder H of an existing roll paper P. This eliminates the need to replace the entire paper holder H, which is expensive, when taking infection prevention measures against new types of infectious diseases, etc. Simply attaching the roll paper cutter 1 makes it possible to easily and inexpensively seal off one of the infection routes, allowing infection prevention measures to be implemented without succumbing to the speed at which the infectious disease spreads.
[0057] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present disclosure.
[0058] For example, in the above embodiment, the cutter body 10 is configured to include one main body portion 11, but this configuration is not necessarily required for the present invention. For example, a configuration such as that shown in FIG. 8 is possible. FIG. 8 is a perspective view of a roll paper cutter 1 according to another embodiment of the present invention. That is, the cutter body 10 can be configured to include two main body portions 11a, 11b at a connecting portion 12. In the embodiment of FIG. 8, the main body portions 11a, 11b are formed from rod-shaped material, and their respective fixed ends 111a, 111b are fixed to the tip end (the end opposite the mounting fixture 20) of one connecting portion 12. Note that the main body portion 11 may be formed from a single rod-shaped material, and the center of the main body portion 11 may be fixed to the connecting portion 12 as a fixed portion.
[0059] Furthermore, in the above embodiment, the mounting fixture 20 has the mounting fixture main body 21 and the cover body 22, and the mounting fixture main body 21 is provided with mounting means 211 for mounting to the wall surface W, but the present invention does not necessarily have this configuration. For example, the mounting means 211 may be provided on the cover body 22. Furthermore, the mounting fixture 20 may be configured not to have the cover body 22. When the mounting fixture 20 is configured not to have the cover body 22, the mounting fixture 20 may be configured to be detachable from the cutter body 10. This allows only the cutter body 10 to be replaced if it is damaged. [Industrial Applicability]
[0060] The roll paper cutter 1 disclosed herein is easy to install, inexpensive, and does not require electricity, so it can be used in toilets in hospitals, department stores, crowded commercial facilities, schools, train stations, etc. The market is large not only in Japan but also overseas, and it is an instrument that can prevent the spread of viruses around the world, so it has industrial applicability.
