Description

  The present invention relates to a roll paper holder to which roll paper is attached and used, and further, a roll that can be easily grasped by pulling out the front end of the roll paper when the roll paper is cut. Regarding the paper holder.

  When the roll paper is attached to the roll paper holder, the roll paper is pulled out and cut to an appropriate length before being used. Cut the drawer. In order to repeat these operations, it is necessary to easily pinch the tip of the roll paper that was cut last time. For this purpose, the tip of the cut roll paper is taken out of the roll paper holder storage unit, and further the holder It is required to be open from a part of the blade or the vicinity of the cutter. There has been proposed a method of cutting the roll paper so as to be taken out from the storage portion by a length necessary to meet this demand. (For example, see Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4, Patent Document 5, and Patent Document 6)

JP 2002-85288 A JP2003-153821 JP 2003-135306 A 5-28292 JP 10-43087 JP-A-10-171

However, in Japanese Patent Laid-Open No. 2002-85288 and Japanese Patent Laid-Open No. 2003-153821, slack occurs in the space between the cutter portion and the tip of the cover that are provided to ensure a predetermined length of withdrawal, and the cutting is unstable. Because the blade edge of the cutter sticks out toward you, it gives a sense of fear. On the other hand, in JP-A-2003-135306, the holding of the roll paper up to the cutter is due to the frictional force on one side, so that the cutting is unstable as in the above-mentioned example, and particularly in the case of two-ply roll paper. It is. In addition, since the cutter part comes to the forefront, there is a risk of catching a finger unexpectedly. In actual open flat No. 5-28292, the cutting can be stably performed and the leading end of the roll paper after cutting is opened, but this leading end does not come down and does not change from the cutting position, so it is difficult to find the knob part and surely. In order to pinch it, the opening / closing plate must be separated largely upward, which is inefficient. Japanese Patent Laid-Open No. 10-43087 can secure a holding part of the roll paper to some extent until reaching the cutter, but the cutting is unstable. Japanese Patent Application Laid-Open No. 10-171 is a form that can secure a holding part of roll paper and can also perform cutting stably, but does not get caught by the pressing ridge or the bent part does not return to the original state and hangs down. There is a case. This is particularly noticeable when the pressing amount is deepened to give a margin to the holding portion, or when soft paper quality with weak restoring force is used.

The present invention relates to a roll paper holder that overcomes the above-described problems. When a roll paper is pulled out from the roll paper holder by a required length and cut, the roll paper can be rolled with any paper quality after cutting. With the safety device that can always pull out the end of the paper stably from the roll paper holder by the intended length and keep the end of the roll paper open, and prevent the teeth from being exposed to cut the roll paper, It is an object to provide an optimal roll paper holder for toilet paper that can be operated extremely safely and for kitchen paper similar to toilet paper. It is another object of the present invention to provide a device that can be used on a horizontal table that has been fixed to a vertical wall.

In order to achieve the above object, the roll paper holder of the present invention is provided with a back member and a cover member that can be opened and closed facing each other from both front and back sides of the drawn roll paper. A convex portion extending in a substantially horizontal direction is provided on one side, and a spring member compressed by the convex portion is provided on the other side, and a tip tooth portion is provided on one of the back surface member and the cover member. Further, when the back member and the cover member are closed, the roll paper is sandwiched between the convex portion and the spring member, the paper is cut at the tip tooth portion, and the back member and the cover member are opened. The roll paper is configured to be released from the sandwiching. Further, instead of the configuration of the convex portion and the spring member, the configuration is such that the paper can be fed out in the horizontal direction.
As another configuration, a flip-up member that flips up a part of the roll paper is provided on the cover member.
Further, the cover member has a stopper at the lower end, a spring plate with a spring member arranged so that the tip tooth portion can enter and exit, and the spring plate is received from the cover member side by the spring plate receiving portion and attached to the spring plate. A slider that can slide in the direction of pressing or separating, a spring member that restricts sliding of the slider, and a spring fixing member that fixes one end of the spring member are provided.

According to the present invention, when the roll paper end is pulled out from the roll paper holder and cut, the roll paper can be safely cut, and after the cutting, any paper quality roll paper is necessary for gripping next time. Since the length can be formed stably and the leading end of the roll paper can be opened, there is an effect that the take-out becomes extremely easy.
Furthermore, there is an effect that it can be handled extremely safely by a safety device that prevents exposure of teeth that cut the roll paper. In addition, there is an effect that it can be used not only on a wall but also on a table.

The roll paper holder according to the present invention pulls out the roll paper end 3a from the roll paper 3 in the roll paper holder, slides on the roll paper receiving shaft 5, and a back member 6 provided on the front side of the roll paper holder; When the necessary length is taken out and cut through the cover member 8, the roll paper tip 3b is pulled out by the length that is easy to pinch after cutting, and a roll paper holder that can be opened is realized. Details are described below.

FIG. 1A is a side view of a roll paper holder according to the present invention, in which a roll paper end 3a drawn out from a roll paper 3 attached to a holding shaft 2 slides on the roll paper receiving shaft 5, and the roll paper holder The front surface of the back surface member 6 passes through the front surface of the back surface member concave portion 6a having a concave portion and a convex portion that are both smooth and uncharged in a substantially horizontal direction. As shown in FIG. 2, a coil spring 6A is attached to the back surface member recess 6a so as to cover the recess. Further, a cover member 8 provided with a cover member convex portion 8d that sandwiches the roll paper end portion 3a and engages with the rear surface member concave portion 6a of the rear surface member 6 is provided in front of the rear surface member 6.

When viewed from the side, the cover member 8 has a shape that is bent substantially at the intermediate portion, and as shown in FIG. 1B, a cylindrical coil spring second fixing member 12 is provided at one end across the intermediate portion. Near the middle portion, there are two pieces of shaft portions 8b provided with notches 8a, and cover member convex portions 8d provided with convex portions engaging with the back surface member concave portions 6a, and the two pieces of shaft portions 8b. It consists of the connection part 8c which connects between. Further, at the end of the connecting portion 8c that connects the two pieces of the shaft portion 8b, a spring tooth 4a, 4b, 4c along the tip tooth portion 10 and a spring supported by the tip tooth portion 10 is provided. A plate 11 is provided.

On the other hand, a roll paper receiving shaft 5 is attached between the two side cover 1 so as to connect the two side covers 1 as shown in FIG. A fulcrum member 9 having a columnar convex portion is provided inside each of the side covers 1.

Next, the cover member 8 is mounted between two side covers 1 forming a roll paper holder, and the cover member 8 is on a slit formed in each of the two side covers 1. The two coil spring second fixing members 12 are inserted into the guide holes 15, respectively, and the cutout portion 8 a is set in a state of being fitted to the fulcrum member 9. The shape of the guide hole 15 is such that the set cover member 8 swings around the fulcrum member 9, and the back surface member concave portion 6 a and the cover member convex portion 8 d are attached to the holding shaft 2. The roll paper end 3a drawn out from the paper 3 is closed face-to-face on both sides, and the roll paper end 3a is sandwiched between irregularities engaged with each other via a coil spring 6A, and the roll paper end 3a is inserted into the tip teeth. It has a shape along the locus of the coil spring second fixing member 12 that is traced when pressed against the back surface member 6 by the portion 10.
A coil spring 14 is attached between the coil spring first fixing member 13 attached to the tip of the coil spring second fixing member 12 and the side surface of the roll paper holder, and the shaft portion 8b of the cover member 8 is attracted.

Next, the cutting of roll paper will be described. After holding the leading end portion 3b of the roll paper and pulling out the necessary length, the lower end portion of the cover member 8 is pressed, and the cover member 8 is pressed against the back surface member 6 as indicated by a broken line in FIG. At this time, the cover member 8 rotates around the fulcrum member 9, and the coil spring second fixing member 12 is opened in the side cover 1 while resisting the extension of the coil spring 14 attached to the coil spring second fixing member 12. It moves along the hole 15. At this time, the roll paper end portion 3a is sandwiched between the portions where the concave and convex portions of the back surface member concave portion 6a and the cover member convex portion 8d are engaged via the coil spring 6A, and has a shape conforming to the concave and convex portions, and the roll paper end portion 3a. Is pressed against the base 7 provided at the lower part of the back member 6 by the spring plate 11 supported by the spring members 4a, 4b, 4c, and further pressed against the lower part of the base 7 by the tip tooth part 10. .

If the surface of the jump plate 11 or the pedestal 7 is subjected to surface processing for increasing the friction force, or a member for increasing the friction force is added, the slip prevention effect is enhanced.
Next, in this state, the drawn-out roll paper end portion 3 a is cut by the tip tooth portion 10. When the hand is released from the cover member 8 after the cutting, the cover member 8 returns to the initial state by the restoring force of the coil spring 14.
In the above example, the coil spring 6A formed in the back surface member recess 6a is not limited to this, and may be formed of a plate spring or a cushion material having an equivalent function.

FIG. 6 shows the movement and function of the tip tooth portion 10 and the spring plate 11 at that time. FIGS. 6A, 6B, and 6C show the state in which the tip tooth portion 10 is pressed before the tip tooth portion 10 is pressed. 6 shows each state immediately before returning to the pre-pressing state after cutting when holding and cutting the roll paper front end portion 3b, and in particular immediately before returning to the pre-pressing state in FIG. The state where the roll paper cutting part entangled with the part 10 is peeled off by the jump plate 11 is shown. That is, there is a case where the roll paper cutting portion is entangled with the tip tooth portion 10 and is pulled up as it is, but since the position of the spring plate 11 is set in a position protruding from the tip portion of the tip tooth portion 10 in advance, the tip tooth portion Immediately after the pressing by 10 is released, the pressing by the spring plate 11 is not yet released, so that the entanglement of the cutting portion is released. Then, after that, the jumping plate 11 returns to the initial position.

Next, regarding the trend of the roll paper end 3a, when the cover member 8 is separated from the back member 6, the roll paper end 3a is pushed out from the back member recess 6a by the restoring force of the coil spring 6A, and the roll paper front end. 3b is also released from the tip tooth portion 10 and the pedestal 7, and hangs down from the cutting position by a length corresponding to the length sandwiched between the back surface member recesses 6a, so that the next roll paper tip portion 3b can be easily pinched.

It should be noted that the sagging caused by the back surface concave portion 6a is obviously affected by the depth and quantity of the concave portion, but considering the ease of pinching, the length of the sagging portion is 20 mm or more, preferably 30 mm or more. This is determined by the combination of the depth and quantity of the recesses. For example, it can be calculated by converting into an equivalent circle composed of a plurality of semi-cylinders (radii are r1, r2,...), And the amount of sag is expressed by (π−2) ) × (r1 + r2 + ...) ≧ 20.
Further, when the roll paper end 3a drawn from the roll paper 3 attached to the holding shaft 2 is slid on the roll paper receiving shaft 5, the cover member 8 is used with the coil spring second fixing member 12 as an axis. Rotating and lifting makes work easier.

Instead of the coil spring 6A, the recess may be covered with a cushion material such as sponge. In this case, when the lower end of the cover member 8 is pressed and the cover member protrusion 8d is pressed against the back member recess 6a, the end of the roll paper The portion 3a is sandwiched between the back surface member concave portion 6a and the cover member convex portion 8d via the cushion material.

FIG. 3 shows another embodiment of the form of the cover member 8 and the swing mechanism. The cover member 17 is a mechanism that rotates around a fulcrum 18 as an axis. Further miniaturization is possible by providing the coil spring second fixing member 19 and the coil spring first fixing member 20 in place of the coil spring second fixing member 12 and the coil spring first fixing member 13, respectively. At this time, it goes without saying that the position of the guide hole 15 is changed in accordance with the locus of the second coil spring fixing member.
Furthermore, it goes without saying that the same effect can be obtained even if the cover member 8 or the concave portion of the back surface member 6 is provided with a plate spring or a plate material via various spring members.

FIG. 4 shows another embodiment, and the cover member 17A is structured to rotate around a new fulcrum 18. In this example, a tip tooth portion 10B is arranged at the lower end of the cover member 17A, and two tips arranged in a pair as shown in the plan view of the cover member 17A in FIG. 5 are provided in the vicinity of the tip tooth portion 10B. Coil springs 4A and 4B and three coil springs 4a, 4b and 4c are provided, and the two coil springs 4A and 4B and the base 7A form an interval between the back member 66 and the cover member 17A. . Here, the roll paper end 3a passes between the two coil springs 4A and 4B. Further, the three coil springs 4a, 4b, and 4c function in the same manner as the coil springs 4a, 4b, and 4c shown in FIG. Note that spring plates are attached to the ends of the two coil springs 4A, 4B and the three coil springs 4a, 4b, 4c, respectively.

Thus, in the initial state, the roll paper end 3a is freely opened in the space formed by the back member 66 to which the coil spring 6B is added and the cover member 17A to which the coil spring 8B is added. When the lower portion is pushed, the unevenness of the back surface member 66 and the unevenness portion of the cover member 17A are closed while meshing with each other, and the two coil springs 4A and 4B are compressed. Further, the three coil springs 4a, 4b, and 4c hold the roll paper end portion 3a with the pedestal 7A and are pressed against the pedestal 7A by the tip tooth portion 10B. In this state, the end of the roll paper is held and the roll paper is cut. When the pressing of the cover member 17A is released, the cover member 17A returns to the initial state supported by the two coil springs 4A and 4B, and the leading end 3b of the roll paper hangs down from the gap between the back member 66 and the cover member 17A. It becomes a state.

FIG. 7 shows an embodiment in which the drawn roll paper is automatically cut at the tip tooth portion, and shows the movement and action of the tip tooth portion 25 and the spring plates 28a and 28b. In FIG. 7A, the back member 23 having a long groove portion 23a in the horizontal direction, and the tip tooth portion 25, the stopper 26, and the tip tooth portion 25 which are all long in the horizontal direction are sandwiched between the spring members 27a and 27b. The cover member 24 having the plates 28a and 28b faces each other, and the roll paper end 3a passes between the back surface member 23 and the spring plates 28a and 28b.

FIG. 7B shows a state in which the roll paper is pulled out by a necessary length, and then the cover member 24 is pressed against the back surface member 23. The tip tooth portion 25 is inserted into the groove portion 23a, and the stopper 26 is in contact with the back surface member 23. Stop. At this time, the roll paper end portion 3a is cut by the tip tooth portion 25 inserted into the groove portion 23a. At this time, the roll paper end portion 3a is fixed by the two jump plates 28a and 28b placed in front of the tip tooth portion 25, so that stable cutting is possible. FIG. 7C shows a state immediately before the cover member 24 returns to the state before pressing, and shows a state in which the roll paper cutting portion entangled with the tip tooth portion 25 is peeled off by the spring plates 28a and 28b. That is, it is often the case that the roll paper cutting portion is entangled with the tip tooth portion 25 and pulled up as it is, but since the holding of the roll paper end portion 3a by the spring plates 28a and 28b has not yet been released, the entangled portion is released. . Thereafter, the spring plate 24 returns to the initial position.

In addition, although it is a trend of the roll paper edge part 3a in this case, when the said cover member 24 isolate | separates from the said back surface member 23, the roll paper edge part 3a is the length of the uneven | corrugated | grooved part pinched by the back surface member and the cover member. The length corresponding to the length will hang down from the cutting position, and the tip of the roll paper will be released in a state where it can be easily pinched next time.

In the example shown in FIG. 7, the spring plates 27a and 28b with springs 27a and 27b and the tip teeth portion 25 are provided on the cover member, and the groove portion 23a is provided on the back member 23. The part may be provided on the back member, and the groove part may be provided on the cover member.

FIG. 8 shows a modification of the embodiment shown in FIG. 7, wherein the back member 23 is provided with spring plates 30a and 30b with sponges 29a and 29b, and the cover member 24 is provided with spring plates 28a and 28b with sponges 38a and 38b. Are provided to face each other. Thereby, even when the roll paper tip 3b remains in the groove 23a after the roll paper is cut, these are easily pushed out. 8A and 8B show that the tip tooth portion 25 is on the cover member 24 and that on the back surface member 23, respectively. Also in this example, it goes without saying that the positions of the spring plates 28a and 28b at the time of opening protrude beyond the position of the tip tooth portion 25.
Furthermore, although the spring plates 28a and 28b are independent in the said Example, they may be connected and integrated in part.

FIG. 9 shows the shape of the tip tooth portion 25 shown in FIGS. 7 and 8 in the horizontal direction. The tip tooth portion 25A of FIG. 21A has a monotonous sawtooth shape, and the tip tooth portion 25B of FIG. The heights of the various types of peaks are alternately formed, which works to reduce the initial biting pressure when cutting roll paper. In this case, the number of mountain heights can be increased, and the shape and arrangement of the mountains can be changed.

FIG. 10 shows another embodiment of the roll paper cutting mechanism. As shown in FIG. 10A, the back member 33 is formed with a U-shaped recess 33A extending in the horizontal direction, and two spring members 37a and 37b. Are provided facing forward and spring plates 36a and 36b are added to the respective ends. Further, the lower plate teeth 34 are held by two spring members 35a and 35b on the inner lower surface of the U-shaped recess 33A. As shown in the plan view of FIG. 10C, the lower plate teeth 34 have end portions 34b cut inward, and side portions have inclined portions 34a at both ends with the cuts in between.

On the other hand, the lower end portion of the cover member 31 has a jumper plate receiver 31b and tip teeth 32 against which the jumpers 36a and 36b abut. Here, when the back member 33 and the cover member 31 are closed, as shown in FIG. 10B, the tip teeth 32 of the cover member 31 are moved to the spring plates 36a and 36b added to the spring members 37a and 37b, respectively. Pushing the roll paper end 3a while resisting, it advances along the inclined portion 34a of the lower plate tooth 34, and cuts the roll paper end 3a in the manner of a heel by contact with the end 34b of the lower plate tooth 34 To do. After the roll paper is cut, the cover member 31 is separated from the back surface member 33, but the cut roll paper tip 3b pushed into the U-shaped recess 33A is formed by the jump plates 36a and 36b. Extruded from the recess 33A of the mold.

Further, as an embodiment to be added of the present invention, FIG. 11 is another embodiment showing a roll paper cutting mechanism. The cover member 40 rotates around a fulcrum (not shown) and is overlapped with the back member 42 like 40A. At this time, the tip tooth portion 46 and the spring plate 44 attached to the spring member 45 are along an arc 47. The jump plate 44 comes into contact with a pedestal 43 provided on the back member 42. Specifically, the tip tooth portion 46 and the spring member 45 slide along an arcuate guide member 48 or a groove. This eliminates the side slip between the spring plate 44 and the pedestal 43 when there is no guide for drawing an arc. Although it is conceivable that the pedestal 43 has an arcuate shape, it does not have to be arcuate as long as the contact position with the spring plate 44 is secured.

FIG. 12 shows an embodiment of a method for absorbing the side slip without providing a guide member for drawing an arc with respect to the arc movement of the cover member. The cover member has a predetermined thickness between the back member 42 and the base 48. The cushion member 49 is sandwiched to absorb minute vibrations in the vertical direction.

Further, as an embodiment to be added of the present invention, FIG. 13 is an embodiment showing another configuration of the roll paper holder. The roll paper is placed directly on the bottom plate 112, and the drawn paper is drawn downward through the roll paper receiving shaft 113. At this time, the bottom plate 112 is lowered at the rear, and the paper is drawn out from below. As a result, the roll paper 100 is always pressed rearward to prevent the roll paper from shaking back and forth. The roll paper thus drawn out is guided between the back member 102 and the cover member 101.
A guide shaft 104 is attached to the cover member 101 in a substantially horizontal direction, and a spring member 105 is fixed to the tip thereof. The guide shaft 104 slides in a guide bearing 106 attached to the back member 102 in a substantially horizontal direction. To do. In this configuration, when the cover member is pushed in the horizontal direction until the stopper 108 comes into contact with the back surface member, the paper has a slack portion formed by the convex portion 103 of the cover member and the concave portion of the back surface member 102, and further the jump plate 110 and the base 111. And is cut at the tip tooth portion 109.

Thereafter, when the hand is released from the cover member 101, the cover member returns to its original position, and the leading end of the paper hangs down (hereinafter, the length of sag is referred to as slack). The cover member 101 is provided with a guide plate 107 and a stopper 108, both of which are provided with paper guides having guide side surfaces 107a and 108a as shown in FIG. 13B. For this reason, when the cover member 101 is pushed in, the paper to be cut as shown in FIG. However, the paper guide is not limited in position, shape, quantity, etc., and can be provided long along the side of the convex portion 103 of the cover member. Note that it is preferable that the distance between the guide side surfaces be slightly narrower in the guide plate 107 than in the stopper 108 because a smooth sag is achieved.

Furthermore, as an embodiment to be added of the present invention, FIG. 14 shows a mechanism for generating a sag when the forcible extrusion by the elastic member is omitted. By fitting the concave and convex portions of the back member 133 and the cover member 131 together, slack is formed in the paper 135 sandwiched between the two members, and the paper is cut by bringing the tip tooth portion 132 into contact with the base 134. Next, when the fitting between the two members is released, the paper hangs down. In this case, if the cutting position is set at the back or near the paper hanging position, the cut paper has good tooth separation due to its own weight.

Here, when considering the inclination of the concave and convex portions and the slip of the paper, the inclination angle required for the paper to slide down from a smooth plate without charging is dependent on the difference in paper quality when taking toilet paper as an example. 30 degrees to 40 degrees was necessary. For this reason, the slope of the slip surface needs to be 30 degrees or more.

The inclination angle is when the paper is all on one inclined surface, and the appearance is different when there is an open portion from the final end of the inclination to the cutting position of the paper as in the present application. That is, in FIG. 14, when the lengths 135a to 135b of the paper on the final inclined portion and the lengths 135b to 135c from the inclined end to the cutting position are substantially the same, the paper slides down even with a slight inclination, and the length from the length 135a. 135b <length 135b to 135c
Then, if the inclined end is smooth, it slides down even if it is almost horizontal. However, these are ideal cases and may not go according to conditions due to entanglement with the tip teeth portion, etc., but the presence of the final inclined portion and the length of the paper 135a to 135b <length 135b to 135c
The relationship is a standard. Further, from the above, θ4 <θ2 <θ3 <θ1 may be satisfied, and θ3 and θ1 may be close to 0 (zero) depending on the paper length distribution. Here, only the concave portion and the convex portion in the cover member 131 and the back surface member 1-133 have been described, but it goes without saying that the present invention can also be applied to other components interposed in other regions sandwiching paper.

Furthermore, reference is made to an embodiment to be added of the present invention that forms the sagging. FIG. 15 is another embodiment for producing sagging. As shown in FIG. 15A, the cover member 141 has a pair of left and right arms 141A, and is supported so as to be rotatable about a rotation shaft 144. Further, a flip-up member 142 is disposed between the pair of left and right arms 141A so as to be rotatable about the rotation shaft 143.

Next, a specific operation will be described. In FIG. 15B, the cover member 141 having the tip tooth portion 141a is held so as to cover the two roll paper receiving shafts 147A and the paper 149 drawn to the outside of the 147B. At this time, the flip-up member 142 provided between the pair of left and right arms 141 </ b> A is pressed against the pair of left and right stoppers 146 by the attractive force of the pair of left and right coil springs 145. Next, the cover member is pushed and pushed until the tip tooth portion 141 a contacts the pedestal 148. At this time, the flip-up member 142 is pushed by the pair of left and right stoppers 146 and rotates around the rotation shaft 143. Thus, the paper 149 is lifted by the flip-up member lower end 142a to form a slack portion 149b. In this state, the lower end 149a of the drawn paper is grasped and the paper is cut.
If the cover member 141 is returned to the original position after the cutting, the flip-up member 142 is also returned to the original position, and the slack portion that has been formed hangs down.
Although not shown in the drawing, it is needless to say that the back member can be provided in the form of a roll paper that can be flipped up.
The cover member moving mechanism is not described here, but it goes without saying that the various methods described so far are used.

Further, as an embodiment to be added of the present invention, there is a locking mechanism for the tip tooth portion. FIGS. 16A and 16B show a series of operations of the locking mechanism. In FIG. 16A, the cover member 151 and the back surface member 156 are opposed to each other with a predetermined interval across a paper (not shown) drawn between them, and the lower end portion of the cover member 151 The stopper 161a, the tip tooth portion 152, the spring member 153, the jump plate 154 provided at one end of the spring member 153, the slider 155 that receives the jump plate 154 from the tip tooth portion 152 side by the jump plate receiving portion 155b, A spring member 157 for restricting the sliding of the slider 155 and a spring fixing member 158 for fixing one end of the spring member are provided, and the slider 155 is slidable in a direction in which the slider 155 is pressed against the jump plate 154 (vertical direction in the drawing). .
On the other hand, the back member 156 is provided with a pedestal 156a and a control rod 156b above it.

FIG. 16 (2) G shows a holding member 159A of the slider 155, which has a substantially U-shaped groove, and the slider 155 having a predetermined thickness slides in this groove. Note that a notch 159a is provided in a part of the holding member 159A, and the control rod 156b enters from this part to move the slider 155. Further, in order to improve safety, the slider is not easily controlled from the outside as shown in FIG. 16 (2) H, and the holding member 159B has a rectangular cylindrical shape that completely covers the periphery. ing. Thus, an opening 159b for inserting the control rod 156b is provided in this part.

When the cover member 151 is moved closer to the back surface member 156 from the state of FIG. 16 (1) A, the control rod 156b is inclined by the slider 155 provided to be slidable on the cover member 151 as shown in FIG. Contact surface 155a. Further, when the cover member 151 is pushed in and a predetermined interval is reached, the slider 155 slides while receiving the repulsive force of the spring member 157 as shown in FIG. The part 155b is detached from the spring plate 154. Further, the jump plate 154 and the pedestal 156a approach a position where they substantially contact each other. When the cover member 151 is further pushed in, the stopper 151a hits the back surface member 156 and stops moving as shown in FIG. 16 (1) D. At this time, the control rod 156b moves off the inclined surface 155a of the slider 155 and reaches the depressed portion 155c, and the slider 155 does not move excessively, but the jump plate 154 moves toward the cover member 151 while resisting the spring member 153. At this time, the tip tooth portion 152 cuts the paper sandwiched and held between the base 156a and the spring plate 154. Thereafter, when the cover member 151 is opened, all members return to the initial state shown in FIG. 28A.

The slider 155 and the coated roll bar 156b form a sliding surface by giving the thickness in the direction perpendicular to the paper surface, but any sliding surface can be used as long as it can maintain a sliding relationship with each other. It can be considered as a form. Further, the inclination of the inclined surface 155a need not be a straight line but may be a curved line.
Further, in order to further enhance safety, it goes without saying that the locking mechanism can be arranged at a plurality of locations, for example, it may be arranged at two locations on the left and right sides of the cover member 151. When the relationship between the tip tooth portion and the pedestal is reversed, that is, when the pedestal is set on the cover member side, the position of the slider may be reversed.

As is clear from the structure of the spring plate 154 in FIG. 16 (2) E and the arrangement of the spring member 153 in FIG. 16 (2) F, the cutting plate 154 has a slit through which the tip tooth portion 152 can pass. 154A is provided, and spring members 153 are fixed to both ends.

In addition, an embodiment to be added for paper cutting in the present invention will be described. In other words, the paper shown in FIG. 9 was completely cut off for cutting the paper, but it is not possible to completely separate it, but it can be easily separated by simply pulling lightly. This reference shows its form. In FIG. 17, FIG. 17A shows a state in which the paper 162 is cut by the tip tooth portion 161, but because the tip tooth portion 161 has a special shape, a part of the paper is not connected completely. Is in a state. FIG. 17B shows one form of the tip tooth portion 161, and a part of the valley is cut out of the series of chevron teeth 161 </ b> A. For this reason, the part of this notch 161B is not cut | disconnected. This is generally called a perforation, but compared to the perforations that are commonly used, the cut width 161c is narrowed to such an extent that the paper does not fall naturally. It is extremely narrow, 0.5mm or less compared to some. This is because the normal perforation is set so that it is not easily cut only by pulling, but it is set to be cut by light pulling in the present application.

FIG. 17C is a modified example of the tip tooth portion 161, and two valley portions near the both ends are cut out in a series of chevron teeth 161C. Thereby, even if the cut width is set to be as wide as about 1.5 mm, it can be easily cut by pulling. However, the position and number of the cuts can be freely set from one in consideration of the cut width.

In the above, the shape and number of the concave and convex portions of the back member and the cover member for sandwiching the end of the roll paper and giving a slack after cutting are not limited to the above embodiments, but by opening and closing the back member and the cover member Any structure or technique that can give a sag at the end of the roll paper may be used. Further, the combination of the tooth portion, the surface member, and the cover member is not limited to the combination of the above-described embodiments, and each combination is free. Further, the tip tooth portion is not particularly limited to the above-described embodiment, including the shape of a straight line, a curve, a saw tooth, the sharpness of the tip portion, and the like. In addition, the spring members and sponges shown in FIGS. 6, 7, and 8 can be replaced with cushion members including rubber, etc., and the spring plate portion can be omitted and the cushion members can be used alone.

Furthermore, the roll paper can be separated more easily by applying an antistatic agent to the back member, the cover member, and each member added thereto.
Furthermore, it is possible to impart antifouling and antibacterial effects by coating each surface of each member with titanium oxide or the like.

As mentioned above, although the Example about basic composition was described, although the more specific Example is described below, the said back member is expressed as a main-body part below.

FIG. 18 shows a roll paper holder with an upper cover, which includes a main body 201 and a front cover 221 that is arranged so that it can be opened and closed with respect to the main body 201 by rotating a pair of left and right arms 222 around an arm rotation shaft 204. The pair of arms 222 is attached above the front cover 221 so as to form a space.
Further, a pair of left and right paper receivers 210 are provided on the upper portion of the main body 201. Further, an upper cover 213 is rotatably provided on the upper portion of the main body 201.

More specifically, FIG. 19 is a front view of the roll paper holder with the upper cover 209 removed, and FIG. 19B is a single unit of the upper cover 213 and a pin 212 for rotatably mounting the upper cover. Is shown. FIG. 19C shows a state in which the upper cover 213 is attached to the main body. A pin 212 attached to the upper cover support portion 211 provided above the main body portion 201 is inserted into a pin insertion hole provided in the upper cover 13. It can be inserted into and rotated freely. In addition, in this figure, although it is a display of only one side, it cannot be overemphasized that it forms in the left-right pair.

Next, the paper receiver 209 is provided around the rotary shaft 210 at the upper front of the main body so as to be rotatable, and consists of a pair of left and right. The paper receiver 209 can be rotated approximately 90 degrees upward from the horizontal state, and is normally kept horizontal by a spring member or its own weight. When setting the roll paper, the paper receiver 209 is lifted by the roll paper. The paper receiver 209 is dropped into the shaft hole of the roll paper and set.

20A and 20B show details of each part of the roll paper holder. FIG. 20A shows a state where the upper cover 213 is lifted, and FIG. 20B shows a state where the upper cover 213 and the front cover 221 are lifted.
Inside the main body 201, a pedestal 202 corresponding to the pedestal 156a in FIG. 16A, a main body convex portion 203, a main body convex portion 204, and a main body leaf spring 205 are provided. Further, inside the front cover 221 is provided a paper cutting means 226 configured in the same manner as the front tooth portion 152, the jump plate 154, etc. of FIG. Here, the front cover 221 rotates the pair of arms 222 around the arm rotation shaft 204, so that the main body convex portion 203 pushes the front cover leaf spring 224 of the front cover 221, and the front cover convex portion provided on the front cover 221. 223 pushes in the main body leaf spring 205, and the main body convex portion 204 slides over the front cover convex portion 223 (opposite side of the front cover leaf spring 224) to sandwich the roll paper. Further, the combination of the lock mechanism 225 and the lock release pin 207 is the same mechanism as that shown in FIG.

In FIG. 18, the cover 221 is included in a space formed above the front cover so as to be rotated upward without contacting the upper cover 213. Further, when a new roll paper having an outer shape of 116 mm and a core inner diameter of 37 mm is set on the pair of paper receivers 209, the pair of paper receivers 209 is formed to be rotatable without contacting the roll paper. Further, when the roll paper is set, the position of the paper receiver 209 is determined so that the outer shape of the roll paper does not protrude from the rear part of the main body. As a result, the size of the roll paper holder is reduced to the limit. In addition, the roll paper holder has been shown to be fixed with screws or the like. Can be used by pasting.

The above is a so-called wall-mounted roll paper holder that pulls out the roll paper from the lower side of the roll paper holder. Hereinafter, a so-called desktop roll paper holder that pulls out the roll paper from the side will be described.

FIG. 21 is an external view of a table-type roll paper holder placed on a table, which is composed of a main body portion 251 and a cover portion 261, and the cover portion rotates around an arm rotation shaft 263 via a pair of arms 262. The main body 251 can be opened and closed, and in use, the pair of arms 262 are held by supporting them with cover springs 256, respectively. The main body 251 is provided with a roll paper receiver 257 on which roll paper to be used is placed.

FIG. 22 is a diagram showing the internal structure with the cover portion 261 opened. The main body portion 251 includes a base 252, a main body protrusion 253, a pair of left and right lock release pins 255, a main body leaf spring 254, The cover springs 256 are mounted on the bottom plate 258, and the intervals between the base 252, the body plate spring 254, and the body projection 253 are at least 2 mm or less. It is designed not to be caught in the gap. The bottom plate 258 is inclined so that the pedestal 252 side is below the horizontal plane. Further, the main body convex portion 253, the main body leaf spring 254, and the pedestal 252 are sequentially lowered as compared with the horizontal plane, and the paper feeding in the lateral direction is executed sequentially, so that it can be achieved without any obstacles. It has become. This feeding effect becomes more prominent as the roll paper used becomes thinner. Further, the pedestal 252 is secured at least 10 mm or more from the table surface, so that the end of the roll paper does not come close to the table surface and can be easily pinched.
On the other hand, the cover portion 252 is provided with a cover portion convex portion 264, a paper cutting means 265, and a lock mechanism 266.

FIG. 23 is an external view showing a state in which the roll paper is attached. The end of the new roll paper is pulled out, and the paper is pulled out from the lower side and placed on the roll paper receiver 257. At this time, the roll paper receiver 257 is composed of two rails as shown in FIG. 21, and the rail is inclined so that the main body convex portion 253 side is downward, and is placed on the roll paper receiver 257. The roll of the roll paper 271 is stationary in a state where it hits a stopper (not shown) provided at the lower ends of the two inclined rails. This prevents the roll paper from always being in the same place when the paper is pulled out, and the paper tip from reversing due to inconvenient rolling (so-called backlash).

FIG. 24 is a view showing a state in which the roll paper 271 is set and then the cover portion 261 is returned to the original position so that the roll paper holder can be used. The cover portion 261 is a pair of cover springs attached to the main body portion 251. 256, and the cover 261 and the main body 251 are held in a state where a predetermined gap is maintained.
When actually used from this state, the end of the roll paper is pinched and pulled out in the front horizontal direction to take out a predetermined length, and then the cover 261 is pushed downward, so that the cover 261 is centered on the arm rotation axis. The paper is cut by the action of the paper cutting means 265 and the pedestal 252 while rotating and the cover convex part 264 presses the main body leaf spring 254 to form a slack in the paper sandwiched by the step with the main part convex part. Here, when the hand is released from the cover part 261, the cover part 261 is pushed up to a predetermined position by the pair of cover springs 256, and the end of the roll paper is pushed out of the roll paper holder. The knob part of hangs down.

In addition, if a non-slip rubber or the like is attached to the lower part of the main body of the desktop roll paper holder, stable operation can be performed and unintentional movement can be prevented. Further, if a rotatable stand is attached under the main body 251 itself, the orientation of the holder can be freely changed to a desired direction.

FIG. 25 is a kitchen paper holder which is a roll paper holder for kitchen paper, FIG. 25A is a front view, and FIG. 25B is a side view. Here, the kitchen paper holder includes a main body 301 and a front cover 231 in which a pair of left and right arms 226 is rotated around an arm rotation shaft 311 so as to be openable and closable with respect to the main body 301. The arm 326 is attached above the front cover 321 so as to form a space.
Further, a paper receiver 309 with a pair of left and right paper stoppers 310 is provided on the upper portion of the main body 301.
More specifically, when setting kitchen paper, the shaft hole of the kitchen paper is passed through the left and right paper receivers 309 so as to pass the bridge. At this time, the fitted kitchen paper is restricted from shifting in the left-right direction by the pair of left and right paper stoppers 310, and is prevented from slipping off the paper receiver 309.

FIG. 26 shows details of each part of the kitchen paper holder, and shows a state where the front cover 321 is lifted.
Inside the main body 301, a pedestal 302, a main body leaf spring 304, and a main body protrusion 305 are provided in this order. In addition, a paper cutting means 322 and a front cover convex portion 323 corresponding to the tip tooth portion 152 and the spring plate 154 of FIG. Here, the front cover 321 rotates the pair of arms 326 around the arm rotation shaft 311, so that the front cover protrusion 323 pushes the main body leaf spring 304 of the main body 301 and the lower part of the main body protrusion 305 enters. Insert kitchen paper. Further, the combination of the lock mechanism 324 and the lock release pin 306 is the same mechanism as that shown in FIG.

When the front cover 321 is rotated with the kitchen paper set, the front cover 321 is included in a space formed above the front cover 321 without touching the kitchen paper and the paper receiver 309. It is formed so that it can be rotated. Further, as shown in FIG. 27, when new kitchen paper is set on the pair of paper receivers 309, the paper receiver 309 is installed via the paper receiver support part 308 so that the outer shape of the kitchen paper does not protrude from the rear part of the main body. Has been

Further, when the front cover 321 is pushed into the main body 301, the main body convex portion 305 is installed so as to be positioned at the upper space position without interfering with the front cover 321, but this causes the main body convex portion 305 to be located. Since the height of the part 305 can be increased and the amount of kitchen paper to be sandwiched can be increased, as a result, the amount of drooping of the kitchen paper after cutting can be increased.

Further, an inclination assisting means 310 is provided on the upper portion of the front cover 321, and the kitchen paper can be easily slid down while maintaining an appropriate space between the main body 301 and the front cover 321 held by the front cover spring 307. However, instead, it is possible to increase the inclination of the upper portion of the front cover convex portion 323 and substitute it.

Furthermore, as shown in FIG. 25A, there is a character notation 331 on the front surface of the front cover 321, which can be decorated with a design or a photograph, and further used with an electronic image display device attached. But you can. When such an electronic display device is attached, although not shown here again, a switching device is provided between the front cover 321 and the main body 301 so that the displayed image is switched each time the front cover is pressed. It is also possible to form it.

The kitchen paper holder is of a type that is fixed to the wall with screws or magnets, but the following is related to a desktop type kitchen paper holder that can be placed on a table or the like.

FIG. 28 is an external view showing a state in which a desktop kitchen paper holder is placed on a table and the cover portion 371 is lifted and opened. Like the kitchen paper holder, it is roughly divided into a main body portion 351 and a cover portion 371. .
The cover portion 371 is openable and closable with respect to the main body portion 351 via a pair of arms 375 rotating around an arm rotation shaft 373. When the cover portion 371 is placed in a usable state, the pair of arms 375 can be opened. Each is held by being supported by a cover spring 356. In addition, the main body 351 includes a kitchen paper receiver 357 on which the kitchen paper to be used is placed, a kitchen paper guide 358 that prevents a lateral shift of the kitchen paper, a pedestal 352, a main body convex 353, a pair of lock release pins 355, a main body A leaf spring 354 and a pair of cover springs 356 are attached on or attached to the bottom plate 361. The pedestal 352 is secured at least 10 mm above the table surface, and the end of the kitchen paper is easy to pinch. It is like that.

A pair of kitchen paper pressing arms 359 is rotatably attached to the side of the kitchen paper guide 358 from the side of the main body, and the end of the kitchen paper pressing arm 359 has a shape that follows the shape of the main body convex portion 353. 360 is fixed. Here, when the roll paper presser arm 359 is rotated, the kitchen paper presser 360 overlaps the main body convex portion 353.
On the other hand, the cover part 371 is provided with a cover part convex part 372, a paper cutting means 373, and a lock mechanism 374.

FIG. 29 is an external view showing a state in which the kitchen paper is attached (loaded). The end of the new kitchen paper is drawn out and placed on the kitchen paper receiver 357 in a state where the paper is pulled out from the lower side. At this time, the kitchen paper receiver 357 is inclined so that the main body convex portion 353 side is downward, and the roll of the kitchen paper 381 placed on the kitchen paper receiver 357 is stationary while being in contact with the stopper 362. This prevents the tip of the kitchen paper from moving due to inconvenient rolling when the kitchen paper is pulled out and stays in the same place stably. In addition, the structure which prevents the inconvenient rolling of kitchen paper by the combination of the kitchen paper receiver 357 and the stopper 362 is not limited to this, and the inclination and arrangement are reversed, or the kitchen paper receiver itself is V-shaped or It is also possible to use a U-shaped groove or lightly hold the roll of kitchen paper itself.

FIG. 30 shows a state in which a pair of kitchen paper presser arms 359 supporting the kitchen paper presser 360 is rotated so that the drawn kitchen paper is sandwiched between the main body convex portion 353 and pulled out. This prevents extra slack from appearing on the kitchen paper. In particular, when the perforations are long and many so that they can be easily cut by the perforations, this sagging prevention means is very important because rapid bending occurs. Furthermore, in order to strictly prevent this sagging, it is also conceivable to form a paper guide for smoothly guiding the paper from the kitchen paper drawer portion on one or both of the inside of the main body 351 and the cover 371. . As an example, it is conceivable to provide a member that smoothly connects between the stopper 362 and the main body convex portion 353.

FIG. 31 is a view showing a state in which the kitchen paper 381 is set and the kitchen paper presser 360 is set and then the cover portion 371 is returned to the original state so that the kitchen paper holder can be used. The cover portion 371 is attached to the main body portion 351. The pair of cover springs 356 are held, and the cover 371 and the main body 351 are held in a state where a predetermined gap is maintained.

In the above-described series of operations, the kitchen paper presser 360, the kitchen paper presser arm 359, the cover part 371, and the arm 375 are always formed so as not to interfere with each other with a new kitchen paper set. Needless to say.
In actual use from this state, the end of the kitchen paper is pinched and pulled forward in the horizontal direction to take out a predetermined length, and then the cover 371 is pushed downward. At this time, the cover portion 371 rotates around the arm rotation shaft 373, and the cover convex portion 372 pushes the main body leaf spring 352, cutting the paper while forming a slack in the kitchen paper sandwiched between the steps with the main body convex portion. The kitchen paper is cut by the action of the means 360 and the pedestal 352. Here, when the hand is released from the cover part 371, the cover part 371 is pushed up to a predetermined position by a pair of cover springs 356, and the end of the kitchen paper is pushed out of the kitchen paper holder, and the top of the base 352 is next. The knob part of hangs down.

The kitchen paper presser 360 is not limited to a structure that overlaps with the main body convex portion 353 without any gap, and the width that allows the kitchen paper to pass smoothly without being influenced by the bends formed on the kitchen paper is 15 mm or less. You may leave space.
Furthermore, the kitchen paper presser 360 may be fixedly arranged instead of rotating.
In addition, when a non-slip rubber or the like is attached to the lower part of the main body of the desktop kitchen paper holder, stable operation is possible and unintentional movement can be prevented.

In addition, about the said kitchen paper presser 360, it can apply also to the type fixed to the said wall, without staying in a desktop type.
The specific structure of the roll paper holder and the kitchen paper holder has been described above, but it goes without saying that the parts and structure of both can be interchanged.

When the roll paper holder of the present invention pulls out the roll paper from the holder and cuts the required length, the leading end is opened without the remaining leading end adhering to the holder, hidden behind the cover, or entangled with the cutter. Since it can be held in such a state, it is easy to pull out next, and is particularly suitable as a soft paper quality or double roll toilet paper holder. In addition, it has a wide range of applications, such as kitchen paper and a holder for food packaging films that use materials that easily get tangled in the cutter.
