Description

The present invention relates to a roll paper drawer capable of smoothly drawing and cutting roll paper such as toilet paper.

As a device that allows toilet paper to be smoothly drawn out and cut with one hand, as described in JP-A-2001-275881, a paper storage unit that stores a plurality of roll-shaped papers in a rotatable state; and A paper outlet that can be taken out in a state where the paper drawn from a plurality of roll-shaped papers stored in the paper storage part is overlapped with each other, and a paper located in a state of being overlapped with the paper outlet is cut by cutting. A paper holder provided with a cutting mechanism is proposed.

By adopting such a configuration, it becomes possible to pull out the required length of paper in a stacked state from the paper outlet and cut it with the cutting mechanism as it is. The cutting operation can be performed with only one hand, and the operation of folding or winding the drawn paper can be simplified.

As the cutting mechanism, a cutting blade that moves up and down with respect to the overlapped paper, a blade cover member that covers a cutting edge of the cutting blade until the cutting blade descends and contacts the paper, and a lowering of the cutting blade By providing a paper locking member that sometimes presses the paper, the paper can be locked and cut by a series of operations, so that operability is improved. Moreover, since the cutting blade covered with the blade cover member is exposed only when the paper is cut, safety is improved.

Further, the cutting edge of the cutting blade is prevented from being exposed from the blade cover member until the cutting blade is lowered and at least one of the blade cover member and the paper locking member contacts the overlapped paper. By providing the stopper member that performs this, it is possible to prevent the fingers from being damaged when the cutting blade is mistakenly lowered while the fingers are interposed between the cutting blade and the paper.
JP 2001-275881

However, in such a configuration, when the cutting blade is lowered, the paper pressing portion that presses the two front and rear points of the paper is too far away, so that the paper is easily stretched when the tip of the cutting blade presses the paper, There is a problem that the paper cannot be cut smoothly. As a result, it is necessary to increase the stroke of the cutting blade, and it can be applied only to a device having a large height dimension containing a plurality of roll papers. Therefore, not only the apparatus becomes large, but also the cutting operation becomes troublesome because the cutting stroke becomes long.

Moreover, although it has the structure which has the cutting blade which raises / lowers with respect to paper, and the blade cover member which covers the blade edge | tip of the said cutting blade until the said cutting blade descend | falls and contacts the said paper, the structure is complicated. is there. In addition, the cutting blade is usually covered with a blade cover member, but it is dangerous because it is exposed when the paper is cut. Since the cutting blade is exposed in this way, a special safety mechanism is provided, such as a stopper member that prevents the cutting edge of the cutting blade from being exposed from the blade cover member. A large operating force is required for the operation, and the cutting operation becomes heavy.

The technical problem of the present invention pays attention to such a problem, and can be safely and safely cut by a child with a light operation force. Also, the roll paper can be pulled out smoothly and reliably by pinching the gripping margin with only one hand operation. It is possible to simplify the structure and reduce the cost.

The technical problem of the present invention is solved by the following means. According to the first aspect of the present invention, the cutting position moves relative to the cutting blade in a state where both the front and rear sides of the cutting position of the roll paper are sandwiched and pressed by the paper pressing means composed of the cutting blade side frame and the paper pushing portion. In the structure, the paper pressing means on the cutting blade side frame side is convex on the cutting blade side and concave on the outside, and the paper pressing means on the paper pushing part side is conversely concave on the cutting blade side. Thus, the roll paper drawer is characterized in that the outer side is convex and the concave part near the cutting blade on the front and rear sides is at least the edge part near the cutting blade is removed.

In this way, the roll paper has a structure in which the cutting position moves relative to the cutting blade and is cut in a state where both sides of the cutting position of the roll paper are sandwiched and held by the paper pressing means. The roll paper is cut in a state where both the front and rear sides of the cutting position are held by the paper pressing means. As a result, when the roll paper is pushed by the blade edge of the cutting blade, the elongation of the roll paper is extremely small, and the roll paper is cut smoothly and reliably. Moreover, the relative stroke of the cutting blade required for cutting can be shortened, and the apparatus can be miniaturized.

Further, the paper pressing means on the cutting blade side frame side is convex toward the cutting blade, and the outside thereof is concave, while the paper pressing means on the paper pushing portion side is conversely concave toward the cutting blade, and the outside is Since the concave portion near the cutting blade on the front and rear side is at least the edge portion near the cutting blade is removed and does not contribute to cutting, the generation of chips can be prevented.

The roll paper drawer according to claim 1, further comprising a paper pushing means that advances and retreats into a cutting blade concave chamber that covers both front and rear surfaces of the cutting blade. is there. In this way, since the paper pushing means is advanced and retracted into the cutting blade concave chamber covering both the front and rear surfaces of the cutting blade, the roll paper is cut at the tip of the paper pushing means when cutting the roll paper. In the state where the vicinity of the position is covered, the paper pushing means enters the cutting blade concave chamber, and the cutting position of the roll paper is pressed against the cutting blade and cut. Thus, since cutting is performed with the paper pushing means entering the cutting blade recess chamber in which the cutting blade is housed, the cutting blade is not exposed and safety is ensured.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the cutting blade recessed chamber is configured to retreat with the paper pushing force of the paper pushing means and the cutting blade protrudes from the cutting blade. It is a roll paper drawer of description. In this way, during the cutting operation, the cutting blade recess is retracted from the cutting blade by the paper pushing force by the paper pushing means and the cutting blade protrudes, so that the cutting position of the roll paper can be adjusted. In a state where the cutting position of the roll paper is sandwiched and pressed between the paper pressing portion of the cutting blade concave chamber and the tip of the paper pushing means, the paper is cut by moving to the fixed cutting blade side. As a result, the paper fed out for the paper pushing and the subsequent cutting operation becomes a gripping margin, and a gripping margin for the next pulling operation is secured.

According to a fourth aspect of the present invention, the left and right ends of the paper pushing means are connected to an operating means that reciprocates by one-hand operation with a wire or other wire material. It is a roll paper drawer of description. Thus, the left and right ends of the paper pushing means are connected to the operating means that reciprocates by one hand operation with wires or other wires, so when the operating means is reciprocated by one hand operation, Since the left and right ends of the paper pushing means move forward and backward with respect to the cutting blade side, the roll paper can be easily cut by one-hand operation.

According to a fifth aspect of the present invention, there is provided means for elastically holding a feeding portion from the roll paper between the cutting blade concave chamber and the paper pushing means. The roll paper drawer according to any one of the above. In this way, between the cutting blade concave chamber and the paper pushing means, there is means for holding the feeding part from the roll paper with elasticity, and this elasticity holding part for holding the fed paper. Since the paper in the region between the cutting blade tip position and the cutting blade hangs down after the cutting operation and becomes a gripping margin when the roll paper tip is pulled out next, the pulling operation of the roll paper tip becomes easy. Further, since the roll paper feeding portion is held by elasticity, it is possible to prevent the gripping margin portion from being rewound into the roll paper storage portion.

According to a sixth aspect of the present invention, a corrugated slit plate is provided between the cutting blade concave chamber and the paper pushing means, and a leading end of the roll paper can be pulled out through the corrugated slit. It is a roll paper drawer according to any one of claims 1 to 5. As described above, the corrugated slit plate is provided between the cutting blade concave chamber and the paper pushing means, and the leading end of the roll paper is drawn out through the corrugated slit, so that the roll paper is flexible, The wavy portion increases rigidity and strengthens the waist. As a result, even when the roll paper leading edge is pulled out and used, the roll paper leading edge side after cutting is in a state where the portion near the wavy slit stands or rises with its own rigidity, Since it acts as a grip margin when pulling out the roll paper, a structure for pulling it upward is also possible. In addition, it is possible to prevent paper jams due to the gripping portion being folded by its own weight.

Since the structure is such that the cutting position moves relative to the cutting blade and is cut in a state where the front and rear sides of the cutting position of the roll paper are sandwiched and pressed by the paper pressing means as in claim 1, The roll paper is cut in a state where the front and rear sides of the cutting position of the roll paper are sandwiched and pressed by the paper pressing means. As a result, when the roll paper is pushed by the blade edge of the cutting blade, the elongation of the roll paper is extremely small, and the roll paper is cut smoothly and reliably. Moreover, the relative stroke of the cutting blade required for cutting can be shortened, and the apparatus can be miniaturized.

Further, the paper pressing means on the cutting blade side frame side is convex toward the cutting blade, and the outside thereof is concave, while the paper pressing means on the paper pushing portion side is conversely concave toward the cutting blade, and the outside is Since the concave portion near the cutting blade on the front and rear side is at least the edge portion near the cutting blade is removed and does not contribute to cutting, the generation of chips can be prevented.

Since the paper pushing means that moves forward and backward in the cutting blade concave chamber covering both the front and rear surfaces of the cutting blade is provided as in claim 2, a roll is placed at the tip of the paper pushing means when cutting the roll paper. In a state where the vicinity of the cutting position of the paper is covered, the paper pushing means enters the cutting blade concave chamber, and the cutting position of the roll paper is pressed against the cutting blade and cut. Thus, since cutting is performed with the paper pushing means entering the cutting blade recess chamber in which the cutting blade is housed, the cutting blade is not exposed and safety is ensured.

As described in claim 3, during the cutting operation, the cutting blade recessed chamber is retreated by the paper pushing force of the paper pushing means with respect to the cutting blade so that the cutting blade protrudes. In a state where the cutting position is pressed with the cutting position of the roll paper sandwiched between the paper pressing portion of the cutting blade concave chamber and the front end of the paper pushing means, the cutting is moved to the fixed cutting blade side and cut. As a result, the paper fed out for the paper pushing and the subsequent cutting operation becomes a gripping margin, and a gripping margin for the next pulling operation is secured.

As in claim 4, since the left and right ends of the paper pushing means are connected to the operating means that reciprocates by one hand operation with wires or other wires, when the operating means is reciprocated by one hand operation, Since the left and right ends of the paper pushing means move forward and backward with respect to the cutting blade side via the wire, the roll paper can be easily cut by one-hand operation.

As in claim 5, there is provided means for elastically holding the feeding portion from the roll paper between the cutting blade concave chamber and the paper pushing means, and in order to hold the fed paper, Since the paper in the area between the elastic holding part and the cutting blade tip position hangs forward after the cutting operation and becomes the gripping margin when the roll paper tip is pulled out next, the pulling operation of the roll paper tip is easy. Become. Further, since the roll paper feeding portion is held by elasticity, it is possible to prevent the gripping margin portion from being rewound into the roll paper storage portion.

As in claim 6, a corrugated slit plate is provided between the cutting blade concave chamber and the paper pushing means, and the leading end of the roll paper is drawn out through the corrugated slit. Regardless, the wavy portion increases rigidity and strengthens the waist. As a result, even when the leading end of the roll paper is pulled upward and used, the leading end of the rolled paper stands with its own rigidity and acts as a gripping margin when the roll paper is pulled out next. A structure that pulls upwards is also possible. In addition, it is possible to prevent paper jams due to the gripping portion being folded by its own weight.

Next, an embodiment of how the roll paper drawer according to the present invention is actually realized will be described. The roll paper drawer according to the present invention includes a type that pulls out from the roll paper and a type that pulls out upward. FIG. 1 is a perspective view showing the whole of the front-side drawer type, and has a paper pushing frame 1 and a cutting blade concave chamber frame 2 as paper pushing means in front of a storage box of toilet paper R which is roll paper. A push-down handle 3 for driving the paper pushing frame 1 up and down is disposed on the back.

Pulleys 41 to 44 are pivotally supported on the left and right side wall outer surfaces of the storage box in the vertical and horizontal directions, and wires 5 are wound around these four pulleys 41 to 44. The wire 5 is connected to the left and right ends 3a of the lower end of the handle 3 between the upper and lower pulleys 41 and 42 on the back, and between the upper and lower pulleys 43 and 44 on the front, A slide plate 1p protruding left and right from both ends is connected. As a return spring for returning and raising the handle 3, a wire spring 6 formed by bending a wire in a U shape is provided on the outer surfaces of the left and right side walls, the lower end is fixed to the side wall of the storage box, and the upper end is connected to the lower end 3a of the handle 3. It is.

Therefore, when the handle 3 is pushed down with one hand, the wire 5 runs counterclockwise, the front paper pushing frame 1 is pulled up and pushed into the upper cutting blade concave chamber frame 2, and further the cutting blade concave chamber. The frame 2 is pushed up, and the roll paper is cut by an internal cutting blade. Then, when the hand is released from the handle 3, the handle 3 is pushed up by the return spring 6, so that the wire 5 runs backward in the clockwise direction, the cutting blade concave chamber frame 2 is lowered by the spring force, and the paper pushing frame 1 Descends and returns. As a result, the cut portion at the upper end of the cut paper descends while being held at the upper end of the paper push-in frame 1 and is exposed to the roll paper pull-out port 14, so that the cut paper can be taken and used. Further, the leading edge of the roll paper is exposed as a gripping margin at the time of next drawing.

FIG. 2 is a longitudinal sectional view showing details of the paper cutting mechanism, and FIG. 3 is an enlarged view of a main part thereof. Inside the cutting blade concave chamber frame 2, the left and right ends of the strip plate-like long cutting blade 7 are fixed to the left and right side walls of the storage box. Therefore, the cutting blade 7 is always in a fixed state, and only the cutting blade concave chamber frame 2 is driven up and down by the lower paper pushing frame 1. The lower portion of the cutting blade concave chamber frame 2 that goes up and down along the guide projections protruding from the inner surfaces of the left and right side walls is a concave chamber so that the upper portion 1u that becomes the paper pushing portion of the lower paper pushing frame 1 can enter. 8, and a small convex portion 10, 10 that faces downward toward the slit 9 through which the cutting blade 7 enters and exits is provided on the ceiling surface of the concave chamber 8. Small concave portions 11 and 11 are formed between the small convex portions 10 and 10 and the front and rear concave chamber 8 inner walls 10i and 10i. The lower ends of the inner walls 10i and 10i of the concave chamber 8 are inclined so as to widen toward the end so that the paper push-in portion 1u can easily enter. Since the tension spring 12 is stretched between the ceiling portion and the upper end of the cutting blade 7 in the internal space of the cutting blade concave chamber frame 2, the cutting blade concave chamber frame 2 always faces downward as indicated by an arrow a1 by the spring force. Has been pulled by.

The upper portion 1u of the paper push-in portion 1 is sized to enter the concave chamber 8 of the cutting blade concave chamber frame 2, and has a slit 13 into which the cutting blade 7 enters in the middle. The side closer to the slit 13 of the paper push-in portion 1u is lowered by one step, such as 1b and 1b, and is formed in a step shape by the convex portion 1a and the concave portion 1b. Therefore, as shown in FIG. 3, when the paper push frame 1 is raised while the roll paper leading end R1 drawn from the roll paper R covers the upper side 1u of the paper push frame 1, the paper push portion 1u is moved into the concave chamber. Enter 8th. And when it further rises, the convex portions 1a and 1a enter into the small concave portions 11 and 11, and the small convex portions 10 and 10 enter into the concave portions 1b and 1b. Then, the paper R1 to be cut is sandwiched. As a result, the paper push-in portion 1u further rises with respect to the cutting blade 7 and is cut while the roll paper leading end R1 is sandwiched between these irregularities. That is, as the paper pushing frame 1 rises due to the wire travel, only the cutting blade concave chamber frame 2 is further pushed up against the tension spring 12, and the cutting blade 12 protrudes downward to perform cutting.

As described above, the front and rear sides adjacent to the cutting blade 7 have the concave portions 1b and 1b and the small convex portions 10 and 10 that enter the concave portions 1b and 1b, and the convex portions 1a and 1a and the convex portions 1a and 1a enter the outside thereof. The cut edge 7 is cut by the cutting blade 7 in a state where the cutting position of the roll paper tip R1 is sandwiched between the concave and convex portions in a wave shape like a chain line. As a result, the cutting force of the cutting blade 7 is applied in a state where both the front and rear sides near the paper cutting position are held, and the paper is hardly stretched, so that it is easily and reliably cut. As shown in FIG. 1, the slide plates 1p at both ends of the paper push-in portion 1 move up and down in the slits S formed on the left and right side walls of the storage box, but slide to the upper end of the slit S when the cutting of the paper is completed. When the plate 1p hits, it cannot be raised any further. Therefore, the size of the entire roll paper drawer is such that it protrudes from the roll paper storage box by the rising dimension of the cutting blade concave chamber frame 2 and is miniaturized. When the roll paper drawer is installed on the wall surface side, the handle 3 is not particularly disturbed if the handle 3 is disposed on the wall surface side.

When the cutting is completed and the hand is released from the handle 3, the wire 5 runs in the opposite direction by the spring force of the U-shaped return spring 6, and the paper pushing frame 1 is pulled down and lowered. At that time, the cut paper, the cutting blade concave chamber frame 2 and the paper push-in frame 1 are lowered together, and when the cutting blade concave chamber frame 2 hits the stopper on the cutting blade 7 side and stops, the cut paper is thereafter cut. When the two of the paper push-in frame 1 descend and the slide plate 1p hits the lower end of the slit S, the descent stops as shown in FIG. In this state, the cut paper may have its upper end attached to the upper part of the paper push-in frame 1, but can be easily separated even with a slight wind.

On the other hand, the leading end R1 on the roll paper side remains as a gripping margin. In order to leave this gripping allowance, a fixed partition plate 15 and an open / close partition plate 16 are provided between the roll paper storage chamber and the roll paper drawer window 14 as shown in FIG. That is, the upper end of the open / close partition plate 16 overlaps the outer surface of the lower end of the fixed partition plate 15 by about several millimeters. The lower end of the open / close partition plate 16 is rotatably supported by a support shaft 17, and the upper end of the open / close partition plate 16 is elastically pressed against the lower end outer surface of the fixed partition plate 15 by a weak spring (not shown).

In this configuration, the upper end of the opening / closing partition plate 16 is pushed open to the roll paper drawer window 14 side, and the leading end R1 of the roll paper R is pulled out from the upper end of the opening / closing partition plate 16 in advance. As a result, the gripping margin R1 hangs down to the roll paper extraction window 14 side while the roll paper leading end R1 is always held between the lower end of the fixed partition plate 15 and the upper end of the open / close partition plate 16 with a weak spring force. It will be. Therefore, the gripping margin R1 is pinched and the roll paper is pulled out by an appropriate amount, and the handle 3 is pushed down to perform the cutting as described above. The length between the blade edge and the blade edge remains as the gripping margin R1, and hangs down toward the roll paper pull-out window 14 as shown in FIG. In addition, although the illustrated cutting blade 7 has a lower end formed in, for example, a saw blade shape, a scissor shape in which one end of the cutting blade 7 rotates about an axis may be used.

If only the cutting blade concave chamber frame 2 is lifted up by hand, for example, the cutting blade 7 inside is exposed and dangerous. Therefore, as shown in FIG. 1, the stopper shaft 18 that rotates with the rear end of the crank portion inserted in the guide groove G formed on the inner surface of the lower plate portion of the handle 3 is provided on the inner surface of the cutting blade recess chamber frame 2. It extends to. The tip of the stopper shaft 18 is bent in an L shape and faces the upper side of the blocking projection provided on the inner surface of the cutting blade concave chamber frame 2. Therefore, even if the handle 3 is pushed down, the stopper shaft 18 cannot rotate until a certain point in time, and the tip of the stopper shaft 18 faces the upper side of the blocking projection, so that only the cutting blade concave chamber frame 2 is raised. Can not. However, when the upper end of the paper pushing portion 1 approaches the lower portion of the cutting blade recess chamber frame 2, the stopper shaft 18 rotates by the action of the guide groove G on the inner surface of the plate portion of the handle 3, and the tip of the stopper shaft 18 is moved. Since it warps from the upper side of the blocking projection, the cutting blade concave chamber frame 2 can be raised. In this way, the stopper shaft 18 cannot rotate until the paper pushing portion 1u rises through the roll paper drawer window 14 and approaches the cutting blade recess chamber frame 2, and the tip of the stopper shaft 18 is above the blocking protrusion. Since it faces each other and only the cutting blade concave chamber frame 2 is prevented from rising, it is possible to prevent the danger of inadvertently lifting only the cutting blade concave chamber frame 2 to expose the cutting blade 7, and it is safe. .

FIG. 6 is a cross-sectional view detailing the cutting mechanism of the roll paper tip R1 in the structure of FIG. 3, and analyzing the cutting action in the cutting process, the cutting blade 7 rather than being cut at the cutting edge 7 In many cases, the upper end edges e and e of the recesses 1 b and 1 b near the cutting blade 7 are sheared between the side surfaces of the cutting blade 7. As a result, since shearing occurs at the two left and right edges e and e, on the roll paper side, a region existing in the gap between both edges e and e is generated as chips, and There is a problem of becoming.

Therefore, in FIG. 7, one edge e is removed and rounded R is added so that the edge e does not exist so that shearing by the edge e occurs only on one side. Therefore, although the roll paper clamping force by the edge e portion is lost, since some remaining concave portion 1bb remains at the rear portion of the edge e, the clamping force by this small concave portion 1bb and the upper small convex portion 10 is Remains. And the clamping force between the convex part 1a and the small recessed part 11 of the outer side is also maintained. As a result, since shearing is performed only between the side surface of the cutting blade 7 and the remaining edge e near the other cutting blade 7, there is only one shearing portion, and generation of chips can be prevented.

Although it is effective to only chamfer the edge e and round it, the narrow slit 13 still remains, and the generation of chips cannot be completely eliminated. Therefore, when the region including the roundness R is cut from the position indicated by the chain line 13a, the portion that presses the roll paper against the cutting blade 7 side is wiped out, so that no chips are generated. In contrast to FIG. 7, the left edge e may be removed, and the edge e may be left on the right side for shearing.

Thus, when cutting by shearing between one edge e and the side surface of the cutting blade 7, the cutting blade 7 is not sharpened on the center line as shown in FIG. It is better to sharpen. That is, when the edge e side is sharpened, the effect is the same as that of shearing with a scissors, and the cutting can be performed smoothly. In addition, the cutting blade 7 may be formed in a sawtooth shape, and only the top end of the mountain may be sharpened on both sides as shown in FIG.

FIG. 4 is a perspective view of a type that pulls upward from the roll paper, and FIG. 5 is a longitudinal sectional view. In this type, on the upper surface of the roll paper storage box, a slit plate 20 having a wavy slit 19 is provided in a roll paper extraction window 14u between the cutting blade concave chamber frame 2 and the paper push-in frame 1. Therefore, if the leading end of the roll paper R is drawn upward from the wavy slit 19, since the drawn roll paper is bent in a wavy shape, the rigidity increases and the paper becomes stronger. As a result, if it is as long as the gripping margin, it can stand upright even when standing vertically, and the portion of the gripping margin is unlikely to be folded by its own weight. Therefore, the opening / closing partition plate 16 that overlaps the fixed partition plate 15 in FIG. 2 is unnecessary. However, the fixed partition plate 15 and the open / close partition plate 16 may be left.

It is the same principle as FIG. 2 and FIG. 3 that the paper pushing portion 1 enters into the concave chamber 8 of the concave blade frame 2 of the cutting blade, and the vertical movement mechanism is merely changed to horizontal movement. . Then, when the handle 3 is pushed down while being pulled out from the wavy slit 19 and standing independently, the paper pushing portion 1 moves horizontally to the cutting blade concave chamber frame 2 side and stands. The paper is cut. The portion between the wavy slit 19 and the cutting blade 7 remains as a gripping margin, and the portion close to the wavy slit 19 is almost self-supporting or raised, and becomes a gripping margin for the next drawing. In this way, the next holding allowance is prepared.

The safety mechanism that prevents only the cutting blade concave chamber frame 2 from moving and the cutting blade 7 from being exposed, and the drive mechanism of the paper push-in portion 1 by the wire are also different from the configurations of FIGS. That is, in this type, only three pulleys 41 and 42 on the upper and lower sides of the back and a pulley 43 on the paper pushing frame 1 side are sufficient. Then, the wire 5 is wound around these three pulleys 41, 42, and 43 in a triangular shape, and the wire 5 is connected to the left and right ends 3a of the lower end of the handle 3. Between the upper pulleys 41 and 43, In FIG. 2, slide plates 1p projecting left and right from both left and right ends of the paper push-in frame 1 are connected. As shown in FIG. 4, the upper end of the U-shaped wire spring 6 for returning and raising the handle 3 is connected to the lower end 3 a of the handle 3.

Therefore, when the handle 3 is pushed down against the U-shaped wire spring 6, the wire 5 travels counterclockwise, the upper paper pushing frame 1 moves horizontally to the handle 3, and the cutting blade on the handle 3 side. It moves to the cutting blade 7 side in the concave chamber frame 2 and is cut. When the hand is released from the handle 3, the handle 3 is pushed up by the U-shaped wire spring 6, and the wire 5 runs backward in the clockwise direction. The teenager remains in a self-supporting state or a raised state.

The exposure of the cutting blade is prevented between the handle 3 and the cutting blade recess chamber frame 2. That is, a clearance space 22 is opened between the handle 3 and the lower plate portion 3p. Since the contact plate 23 protruding to the back from the cutting blade concave chamber frame 2 is normally hitting the plate portion 3p by the restoring force of the cutting blade concave chamber frame 2, the cutting blade concave chamber frame 2 cannot move in the cutting direction, Therefore, the internal cutting blade 7 cannot be exposed. However, when the handle 3 is pushed down and the wire 5 travels counterclockwise and the paper pushing frame 1 approaches the cutting blade recess chamber frame 2, the handle plate portion 3p is formed to pass through the contact plate 23. Therefore, the contact plate 23 protrudes into the escape space 22, the cutting blade recessed chamber frame 2 moves in the cutting operation direction, and the cutting operation is performed. After the cutting of the leading edge of the roll paper is completed, the paper pushing frame 1 returns to its original position, and the cutting blade concave chamber frame 2 also returns to its original position by the return spring 12. Therefore, the handle plate portion 3p is raised and returned to its original position.

In the embodiment described above, the slit 13 into which the cutting blade 7 enters the paper push-in portion 1u is a wide space at the back of the cutting blade 7 and is attached to the tip of the cutting blade 7. It becomes space 1s which can accommodate the chip which exists. Further, since the entrance / exit portion of the cutting blade is narrow, the chips adhering to the cutting edge of the cutting blade are easily caught in the narrow entrance / exit and remain in a wide space. A window hole 1w is opened in the wide space 1s, and internal chips can be easily discharged.

As described above, according to the roll paper drawer according to the present invention, roll paper such as toilet paper can be pulled out easily and reliably with only one hand operation and cut smoothly, and it is small and simple, so it is easy to carry and inexpensive. realizable. In addition, it has a safe structure where the cutting blade is not exposed, so it can be used with peace of mind by children. Therefore, this roll paper drawer can be used outside the toilet, and the use of toilet paper is expanded. Moreover, it can be used for roll paper other than toilet paper.

It is a perspective view which shows the whole content of the roll paper drawer of a near side drawer type. It is a longitudinal cross-sectional view which shows the detail of a roll paper cutting mechanism. It is a longitudinal cross-sectional view of the principal part which shows the state just before clamping of the paper pulled out from the roll paper. It is a perspective view of the roll paper drawer of the type pulled out from roll paper. It is a longitudinal cross-sectional view of the roll paper drawer of FIG. FIG. 4 is a cross-sectional view detailing a roll paper cutting mechanism in the structure of FIG. 3. In this embodiment, the other edge is removed so that only one side has an edge closer to the cutting blade.
