Description

  The present invention is a roll paper holder to which roll paper is attached and used. Further, when the roll paper is cut, the roll paper is drawn out with the leading end of the roll paper open and can easily grip the leading end. It relates to a paper holder.

  When using the roll paper attached to the roll paper holder, pull out the roll paper and cut it to an appropriate length. Cut the drawer. 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 from the storage part of the roll paper holder, 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. Moreover, since the cutter part comes to the forefront, there is a risk of catching a finger unexpectedly. In actual open flat 5-28292, cutting can be done with peace of mind, 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 reliably In order to pinch, the opening / closing plate must be greatly separated 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 be cut stably, but does not get caught by a pressing ridge, or a bent part does not return to its original state and hangs down. There is a case. This is particularly noticeable when the push-in amount is increased in order to provide a margin for the holding portion, or when soft paper 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 always pulls out the end of the paper from the roll paper holder stably for the intended length and keeps the end of the roll paper open, and prevents exposure of teeth to cut the roll paper, An object of the present invention is to provide an optimum roll paper holder for toilet paper that can be operated extremely safely.

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 of the two sides, a concave portion for indenting the convex portion is provided on the other side, a tip tooth portion is provided on one of the back surface member and the cover member, and the concave portion is provided. An expansion / contraction member is provided.
In addition, 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 end of the roll paper 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.

  The roll paper holder according to the present invention draws 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. 1 is a side view of a roll paper holder according to the present invention, in which a roll paper end 3a pulled 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. 7, 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 attached 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 3 is closed face-to-face from both the front and back sides, and the roll paper end 3a is sandwiched between recesses and projections engaged with each other via a coil spring 6A, and the roll paper end 3a is inserted into the tip tooth portion. 10, the shape follows the locus of the coil spring second fixing member 12 that is followed when pressed against the back surface member 6.
A coil spring 14 is attached between the first end of the coil spring second fixing member 12 and the coil spring first fixing member 13 attached to the side surface of the roll paper holder, and attracts the shaft portion 8 b of the cover member 8.

  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, as shown in FIG. 9, the cover member 8 rotates around the fulcrum member 9, and the coil spring second fixing member 12 faces the side surface while resisting the extension of the coil spring 14 attached to the coil spring second fixing member 12. It moves along the guide hole 15 formed in the cover 1. 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.

  FIG. 18 shows the movement and action of the tip tooth portion 10 and the spring plate 11 at that time. FIGS. 18A, 18B, and 18C show the state in which the tip tooth portion 10 is pressed before the tip tooth portion 10 is pressed. 18 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, as shown by the broken line in FIG. The work is facilitated by rotating and lifting the coil spring second fixing member 12 as an axis.

  Next, another embodiment of each part will be described. FIG. 3 shows another embodiment similar to the back surface member recess 6a, in which the recess is covered with a cushion material 6b such as sponge instead of the coil spring 6A. Thus, when the lower end portion of the cover member 8 is pressed and the cover member convex portion 8d is pressed against the back surface member concave portion 6a, the roll paper end portion 3a is uneven by the back surface member concave portion 6a and the cover member convex portion 8d via the cushion material 6b. It is sandwiched in a shape that follows. After the roll paper end 3a is cut, when the hand is released from the cover member 8, the cover member 8 returns to the initial state by the restoring force of the cushion material 6b. FIG. 4 limits the width of the cushion material 6b to reduce the friction between the roll paper end 3a and the cushion material 6c, thereby facilitating separation between the roll paper end 3a and the cushion material 6c. is there. 5 and FIG. 6 are modifications of FIG. 3 and FIG. 4, respectively, in which the separated cushion material 6b and cushion material 6c are simplified as single cushion members 6d and 6e in a substantially vertical direction, respectively. is there.

  FIG. 11 shows another embodiment of the form of the cover member 8 and the swing mechanism, in which a weight 16 is embedded in place of the coil springs 14 attached to the two shaft portions 8b. Thereby, since the action of the gravity of the weight 16 functions in the same way as the coil spring 14, the coil spring and the coil spring fixing member can be omitted and the structure can be simplified. Further, a coil spring 8A is added to the concave portion of the cover member 8, and the combination of the coil spring 6A of the back surface member 6 can restore the deformed roll paper end 3a more effectively.

FIG. 12 shows another embodiment of the form of the cover member 8 and the swing mechanism. The cover member 17 is a mechanism that rotates about a fulcrum 18 as an axis. In place of the coil spring second fixing member 12 and the coil spring first fixing member 13, a coil spring second fixing member 19 and a coil spring first fixing member 20 are provided, respectively, which enables further miniaturization. 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.

In the embodiment, the roll paper 3 is held by the holding shaft 2, but the holding shaft 2 can be omitted. FIG. 13 shows an embodiment of a roll paper holder housing portion, which is composed of a back surface 21A, a bottom surface 21B, two side surfaces 21 and a front surface 22. Here, the shape of the back surface member 66 and the cover member 88 is a device that increases the number of the concavo-convex portions of the shape of the back surface member 6 and the cover member 8 to increase the amount of the roll paper leading end after the roll paper is cut. Thus, the coil springs 8 </ b> B and 6 </ b> B are sandwiched between the front and rear surfaces of the roll paper end 3 a and the concave portions of the cover member 88 and the convex portions of the rear surface member 66.
The cover member 88 has a lower end bent into an L-shape on the roll paper side for the purpose of further pulling down the roll paper tip 3b, and a tip tooth portion 10A is provided at the end.
Here, the tip tooth portion 10A of the cover member 88 presses the roll paper end portion 3a against the pedestal 7A provided in the recessed portion to cut the roll paper.

  The roll paper 3 is thrown and held from the opened top as shown by an arrow. At this time, by providing an inclination on the bottom surface 21B, even when the roll paper is consumed and reduced like the roll paper 3A, the roll paper is stabilized. Can be held. As for the direction of inclination, the roll paper can be stably rotated if the front is lowered when pulled out from above as shown in FIG.

FIG. 14 shows a modification of FIG. 13 in which a cushion material 6C such as a sponge and a cushion material 8C are fitted into the recesses provided in the back surface member 66 and the cover member 88, respectively.
FIG. 15 shows another embodiment relating to opening and closing of the cover member. The fulcrum member 9 is eliminated, and the cover member 88 is directly rotated on the roll paper receiving shaft 5. Thereby, the apparatus can be simplified more than the arrangement in which the cover member 88 rotates around the fulcrum member.

  FIG. 16 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. 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. 19 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. 19A, the back member 23 having a groove 23a that is long in the horizontal direction, and the tip tooth portion 25, the stopper 26, and the tip tooth portion 25 that 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. 19B 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. 19C 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 jump 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. 19, the spring plates 27a and 28b with springs 27a and 27b and the front tooth portion 25 are provided on the cover member, and the groove portion 23a is provided on the back surface member 23. The part may be provided on the back member, and the groove part may be provided on the cover member.

FIG. 20 shows a modification of the embodiment shown in FIG. 19, in which 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. 20A and 20B 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. 21 shows the shape of the tip tooth portion 25 shown in FIGS. 19 and 20 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. 22 shows another embodiment of the roll paper cutting mechanism. As shown in FIG. 22A, the back member 33 is formed with a U-shaped recess 33A extending in the horizontal direction, and two spring members 37a, 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. 22C, 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. 22B, the tip teeth 32 of the cover member 31 are placed on 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. 23 is another embodiment showing a roll paper cutting mechanism. The cover member 200 rotates about a fulcrum (not shown) and is overlapped with the back member 202 like 200A. At this time, the tip tooth portion 206 and the spring plate 204 attached to the spring member 205 are along an arc 207. The jump plate 204 comes into contact with a pedestal 203 provided on the back member 202. Specifically, the tip tooth portion 206 and the spring member 205 slide along an arcuate guide member 208 and a groove. This eliminates a side slip between the jump plate 204 and the pedestal 203 that occurs when there is no guide for drawing an arc. Although it is conceivable that the pedestal 203 also has a shape protruding in an arc shape, this need not necessarily be an arc shape as long as the contact position with the spring plate 203 is secured.

  FIG. 24 shows an example 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 202 and the base 208. The cushion member 209 is sandwiched to absorb minute shakes in the vertical direction.

Furthermore, FIG. 25 is an embodiment showing another configuration of the roll paper holder as an embodiment to be added of the present invention. The roll paper is placed directly on the bottom plate 112, and when the paper is pulled out and the cover member is pushed in the horizontal direction until the stopper 108 comes into contact with the back member, the paper comes into contact with the convex portion 103 of the cover member. A slack portion is formed by the concave portion of the member 102, and is further sandwiched between the spring plate 110 and the pedestal 111 and 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. 25B. 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 according to the present invention, FIG. 26 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. 26, 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 Length 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. 27 is another example of producing a sag. As shown in FIG. 27A, the cover member 141 has a pair of left and right arms 141 </ b> A, 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. 27B, 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 paper drawn out is held and the paper is cut.
After the cutting, if the cover member 141 is returned to the original position, the flip-up member 142 is also returned to the original position, and the formed slack portion 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 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. FIG. 28A shows a series of operations of the lock mechanism. In FIG. 28-1A, 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. 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, and the slider 155 And a spring fixing member 158 for fixing one end of the spring member, and the slider 155 is slidable in a direction in which the slider 155 is pressed against the spring plate 154 (vertical direction in the figure).
On the other hand, the back member 156 is provided with a pedestal 156a and a control rod 156b above it.

  FIG. 28-2G shows a holding member 159A of the slider 155, which has a substantially U-shaped groove on which the slider 155 having a predetermined thickness slides. 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 enhance safety, the slider is not easily controlled from the outside as shown in FIG. 28-2H, and the holding member 159B has a rectangular cylindrical shape that completely covers the periphery. . 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. 28-1A, the control rod 156b comes into contact with the inclined surface 155a of the slider 155 provided slidably on the cover member 151 as shown in FIG. 28-1B. To do. Further, when the cover member 151 is pushed in and a predetermined interval is reached, as shown in FIG. 28-1C, the slider 155 is pushed by the control rod 156b and slides while receiving the repulsive force of the spring member 157, and the jump plate receiving portion 155b. Leaves the jump 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. 28-1D. 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. 28-1A.

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 jump plate 154 in FIG. 28-2E and the arrangement of the spring member 153 in FIG. 28-2F, the jump plate 154 is provided with a slit 154A through which the tip tooth portion 152 can pass. Yes, 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. That is, the one shown in FIG. 21 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 it. This reference shows its form. In FIG. 29, FIG. 29A shows a state in which the paper 162 is cut by the tip tooth portion 161. However, since the tip tooth portion 161 has a special shape, a part of the paper is not connected completely. Is in a state. FIG. 29B shows one form of the tip tooth portion 161, and a part of the valley is cut out of the series of chevron teeth 161A. 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. 29C is a modified example of the tip tooth portion 161, and two valley portions near the both ends are cut out of the 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. 18, 19, and 20 can be replaced with cushion members including rubber or the like, and the spring plate can be omitted and 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.

  When the roll paper holder of the present invention pulls out the roll paper from the holder and cuts the required length, the remaining tip is not attached 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.
