Abstract
Description
Technical Field
[0001] This invention relates to a paper holder for holding a paper roll attached to toilets such as stations and hospitals.
Background Art
[0002] A widely known paper holder is installed in facilities such as hospitals, for example, toilets. When in use, the user presses an arc-shaped cover that covers the paper from above with one hand to stop the rotation of the paper wound in a roll shape, and while pinching the tip of the paper with the other hand, pulls it toward the front side of the user and uses the tip edge of the cover as a cutter to cut the paper. When pulling out paper from a conventional paper holder, since everyone who uses it needs to hold down the cover, especially in the case of those used in public facilities such as hospitals and stations, the hands of an unspecified number of people directly touch it, so there is a possibility that the user will be contaminated with pathogenic bacteria through the cover, which is not hygienically preferable. Also, the user has the trouble of avoiding the places touched by others when using it, which is inconvenient for use. To solve this problem, a toilet paper holder described in Japanese Patent Application Laid-Open No. 2022-69699 (hereinafter referred to as "Conventional Example 1") has been proposed. The paper holder of Conventional Example 1 attaches a thin plate-shaped paper cutting member to the tip edge of the cover that covers the upper side of the toilet paper wound in a roll shape, provides an opening for pulling out the toilet paper in this paper cutting member, and provides a converging cutting portion for converging a part of the pulled-out toilet paper into a substantially bundled shape and then cutting it below this opening. As an example of the usage method of the above paper holder, the user pulls out the toilet paper from the opening of the paper cutting member, converges the toilet paper at the cutting location into a substantially bundled shape in the converging cutting portion, and applies tension left and right to cut it. According to Conventional Example 1, by pulling the toilet paper out from the opening and cutting it at the convergence cutting section, the user does not need to hold the toilet paper down with a cover while pulling it out and cutting it, thus eliminating the need for the user's hands to touch it each time. This is hygienically preferable for the user and is thought to eliminate the inconvenience of use that occurred in the past. [Prior art documents] [Patent Documents]

[Modes for carrying out the invention]
[0008] Embodiments of this invention will be described with reference to the drawings. The paper holder shown in Figures 1 to 4 consists of a holder base A which houses a paper roll R with paper P wound in a roll shape inside in a rotatable and removable manner, a storage casing C attached to the holder base, a paper feeding operation mechanism B (Figure 16) whose main components are located inside the storage casing for feeding the paper forward from the holder base, a paper feeding interlocking propulsion mechanism D (Figure 16) whose main components are located inside the storage casing and which operates in conjunction with the operation of the paper feeding operation mechanism, and a paper cutting mechanism E (Figure 18) located inside the storage casing for cutting the paper at a predetermined position while it is being fed out.
[0009] Based on Figures 1 to 11, the holder base A will be explained in detail. The base body 1 of the holder base A has an opening at the front (left side in Figure 1), which is the side in which the paper P is fed. The base body 1 has approximately inverted L-shaped side frames 1a and 1b on both sides (both sides in the direction intersecting the feeding direction). At the rear of the base body 1 (right side in Figure 1), a back frame 1c is positioned to connect the two side frames 1a and 1b. The back frame 1c can be fixed to a wall, column, or the like. In the base body 1 shown in Figures 5 and 8, a reinforcing plate 1e is fixed to the inside of the upper part of the front frame sections 1a1 and 1b1 of both side frames 1a and 1b. Screw holes 1k for fixing the reinforcing plate are drilled side by side in the front frame sections 1a1 and 1b1 and the reinforcing plate 1e, a roller shaft insertion hole 1f is drilled behind each screw hole, and a vertically elongated guide hole 1g is drilled below the space between the two screw holes. As shown in Figure 8, the reinforcing plate 1e is fastened to the inside of the upper part of both front frame sections 1a1 and 1b1 with screws 3. Casing holding holes 1a3 and 1b3 are provided at the top of the rear frame sections 1a2 and 1b2 of both side frames 1a and 1b, and arc-shaped regulating holes 1a4 and 1b4 are formed on the rear outer side of each casing holding hole. The ends of the casing holding shafts 8, which will be described later, are pivotally attached to the casing holding holes 1a3 and 1b3, and guide pins 11b (Figure 13), which protrude from the rear side of the storage casing C, are movably inserted into the regulating holes 1a4 and 1b4. In addition, a U-shaped roll holding shaft bearing recess 1d is formed in the lower center of both side frames 1a and 1b of the base body 1, from which the shaft end Sa of the roll holding shaft S can be removed. The paper roll R inside the base body 1 has both shaft ends Sa of the roll holding shaft S, which penetrates the cylindrical roll core Ra, rotatably and detachably hooked into the roll holding shaft bearing recess 1d (Figures 3 and 4).
[0010] As shown in Figures 3 to 7, the paper guide board 2 is mounted horizontally between the upper parts of the front frame sections 1a1 and 1b1 of the side frames 1a and 1b of the base frame body 1, so as to extend toward the back frame 1c. As shown in Figure 5, fixing pieces 2a for attaching the paper guide board are bent on both sides of the front of the paper guide board 2, on the inside of the upper parts of the front frame sections 1a1 and 1b1 of the side frames 1a and 1b. Multiple screw holes 2a1 are made in the fixing pieces 2a, and the paper guide board 2 is fixed to the side frames 1a and 1b with screws 3. The paper guide board 2 is attached with screws 3 with each fixing piece 2a sandwiched between the upper parts of the front frame sections 1a1 and 1b1 of the side frames 1a and 1b and the reinforcing plate 1e (Figure 3). In the example shown in Figure 7, the paper guide board 2 has three rectangular roller openings 2b running from front to back in the width direction, and long cutting blade insertion holes 2c are made along each roller opening. Small holes 2d are also made along both sides of the front of the paper guide board 2.
[0011] In Figures 1, 5 to 9, a long paper guide table 4 is positioned between the front upper parts (left side in Figure 9) of the side frames 1a and 1b of the base stand body 1, facing forward in the direction of paper feeding (left side in Figure 1). The rear part of the paper guide table 4 is held by a table holding shaft 5, whose ends are pivotally attached to both side frames 1a and 1b on the base stand body 1. The paper guide table 4 is rotatable about the table holding shaft 5, which is positioned in the table width direction. In Figure 5, reference numeral 1h indicates the shaft hole through which the table holding shaft 5 passes. In Figure 9, the front portion of the paper guide table 4 extends forward from the base body 1. The upper surface of the paper guide table 4, excluding the front extension, is in contact with the lower surface of the paper guide board 2. The paper guide table 4 is intended to guide the paper P, which is pulled out from the paper roll R and fed out via the paper guide board 2, toward the front edge of the table. As shown in Figures 10 and 11, the paper guide table 4 is subjected to the spring force of the first set spring 6, which constitutes the set spring mechanism. The paper guide table 4 is subjected to a spring force by the first set spring 6 that allows it to rotate clockwise.
[0012] Now, let's explain the first set spring 6. The first set spring 6 is a torsion spring, as shown in the example in Figure 10. As shown in Figures 10 and 11, the body of the first set spring 6 is attached to spring mounting pins 7 that protrude from the front upper inner surfaces of both side frames 1a and 1b via reinforcing plates 1e. In Figure 5, 1i is the mounting hole for the spring mounting pin 7, and 1j is the mounting hole for the spring mounting pin 22, which will be described later. One arm 6a of the first set spring 6 elastically contacts the lower outer surface of the roller shaft 37b for the feed driven roller shown in Figure 10 from below, while the other arm 6b elastically contacts the outer surface of the table holding shaft 5 of the paper guide table 4. As described above, the table holding shaft 5 is biased by a spring force from the first set spring 6, which allows for clockwise rotation around the table holding shaft. This spring force prevents the paper guide table 4 from rotating beyond its horizontal position in a clockwise direction, and thus maintains the horizontal position of the paper guide table. In other words, the paper guide table 4's clockwise rotation beyond a predetermined angle is restricted by the paper guide plate 2. The roller shaft 37b will be described in detail later, but the shaft end of the roller shaft 37b at the axis of the feed-driven roller 37 is pivotally supported on the upper side surfaces of both side frames 1a and 1b. Roller shaft insertion holes 1f (Figure 9) for the feed-driven roller 37 are formed in the upper part of the front frame portions 1a1 and 1b1 of both side frames 1a and 1b in a somewhat elongated shape. Within these roller shaft insertion holes 1f, the roller shaft 37b can move up and down according to the spring force of the first set spring 6 applied to this roller shaft.
[0013] The storage casing C will be explained based on Figures 1, 2, and 9-14. The storage casing C is held between side frames 1a and 1b via a casing holding shaft 8. The casing holding shaft 8 is positioned in the width direction between the rear parts (right side in Figure 1) inside the storage casing C, passing through the side frames 1a and 1b, with both ends of the shaft pivotally attached to the upper parts of the rear frame sections 1a2 and 1b2. The storage casing C is rotatable about the casing holding shaft 8 and can be raised and lowered relative to the base body 1. To facilitate the raising and lowering operation of the storage casing C, arc-shaped regulating holes 1a4 and 1b4 are formed on the outside of the upper ends of the rear frame sections 1a2 and 1b2 of both side frames 1a and 1b. Guide pins 11b are inserted and slide within the regulating holes 1a4 and 1b4. The position of the guide pins 11b is regulated at both ends of the regulating holes 1a4 and 1b4, thereby specifying the upright position and the horizontal position of the storage casing C. As shown by the dashed line in Figure 1, circular knobs 9 are provided on both sides of the storage casing C, connected to both ends of the casing holding shaft 8, in order to maintain the upright position of the storage casing C when replacing the paper P. Tightening the knobs 9 prevents the storage casing C from rotating, thereby maintaining the upright position of the storage casing. Elongated guide holes 12 are provided on both sides of the front (left side in Figure 1) of the storage casing C. Both ends of the front connecting shaft 25, which will be described later, are inserted into both guide holes 12 so as to be able to move up and down. Furthermore, as shown in Figures 1, 12, and 13, the storage casing C is assembled so that it can be separated into upper and lower parts by a lower casing 10 and an upper casing 11. In the bottom of the lower casing 10, three rectangular roller openings 10a are provided in a row in the width direction (vertical direction in Figure 12) for the paper feeding main roller 36. The outer circumference of the roller portion 36a of the paper feeding main roller 36 is exposed through each roller opening 10a. Along the roller openings 10a, long insertion holes 10b for the cutting blade are provided in the bottom of the lower casing 10. Long narrow holes 10c are provided on both the front and rear sides of the bottom surface of the lower casing 10. In addition, strip-shaped spacers 13 are provided on both sides of the bottom surface of the lower casing 10 in the width direction. The distance between the two spacers 13 is set to a width that does not obstruct the movement of the paper P. The bottom surface of the lower casing 10 faces the paper guide plate 2 via a spacer 13, and the spacer 13 forms a gap d between the lower casing and the paper guide plate through which the paper P passes (Figure 3). As shown in Figure 14, shaft holes 11a are provided on both rear sides of the upper casing 11 for supporting the casing holding shaft 8, and guide pins 11b are provided protruding from the rear of the shaft holes.
[0014] The paper feeding mechanism B will be described with reference to Figures 12 and 14-23. The paper feeding mechanism B consists of a feeding interlocking mechanism 14, a second set spring 15, a feeding power transmission mechanism 16 that can be interlocked in response to the interlocking force from the feeding interlocking mechanism, and a clutch means 17 that receives the interlocking force transmitted from the feeding interlocking transmission mechanism.
[0015] The feed-out interlocking mechanism 14 will now be described. In Figures 12 and 15-21, the feed-out interlocking mechanism 14 consists of a driving interlocking body 18 and a driven interlocking body 19 that can engage with the driving interlocking body. Each driving interlocking body 18 is located inside the two side frames 1a and 1b. The bases of both driving interlocking bodies 18 are located outside the bottom of the housing casing C and are attached to both ends of the interlocking shaft 20 that connects the two side frames 1a and 1b. Both ends of the interlocking shaft 20 pass through the two side frames 1a and 1b, respectively, and circular knobs 21 are screwed into the shaft ends (Figure 12). By turning the knobs 21 clockwise, the driving interlocking bodies 18 also swing in the same direction. The upper part of the main drive unit 18 rises into the storage casing through the hole 2d in the paper guide plate 2 and through the insertion hole 10c opened in the bottom surface of the storage casing C. The clockwise swing of the main drive unit 18 is not hindered by the hole 2d and the insertion hole 10c. The main drive unit 18 has a hook 18a formed on its upper part, which is directed forward (to the left in Figure 10).
[0016] The driven interlocking unit 19 will be described with reference to Figures 12 and 15 to 21. Both driven interlocking members 19 are positioned on either side of the housing casing C, above each of the driving interlocking members 18. Each driven interlocking member 19 has a hook 19a at its lower end, and the hooks of each driven interlocking member and the hooks 18a of each driving interlocking member 18 are detachably engaged. The lower parts of both driven interlocking members 19 protrude downward from the insertion holes 10c at the bottom of the housing casing C. A rectangular notch 19b is made in the upper part of the driven interlocking body 19, extending forward from the rear (right side in Figure 20) end. The front connecting shaft 25, which is positioned between the side plates of the storage casing C, passes through each notch 19b. The front connecting shaft 25 passes through vertically elongated narrow holes 44c (Figure 36) made in the side plate 44 of the cutting action facilitator 43 of the cutting plate 38, which will be described later. When the driven interlocking member 19 is engaged with the driving interlocking member 18, it sends out the interlocking force from the driving interlocking member and transmits it to the power transmission mechanism 16.
[0017] The second set spring 15 will now be described. The second set spring 15 is located on the upper inner side of the front frames 1a1 and 1b1 of both side frames 1a and 1b. In the examples shown in Figures 15 and 16, each second set spring 15 is a torsion spring. The body of the second set spring 15 is held by spring mounting pins 22 that protrude from the inner surfaces of both front frames 1a1 and 1b1. One arm 15a of the second set spring 15 elastically contacts the table holding shaft 5, and the other arm 15b elastically contacts the lower surface of the paper guide table 4. The second set spring 15 has the role of applying a spring force to the paper guide table 4 so that the paper guide table can return to its original position. That is, if the paper guide table 4, which feeds out the paper P, attempts to rotate counterclockwise around the table holding shaft 5 against the spring force of the second set spring 15, a spring force acts to return the paper guide table to its original position. The clockwise rotation of the paper guide table 4 due to the spring force of the second set spring 15 is restricted by the paper guide plate 2, which is in contact with it on its upper surface. The interlocking shafts 20 that penetrate the bases of both main interlocking units 18 move up and down within the guide holes 1g opened in the upper parts of the front frames 1a1 and 1b1 in accordance with the rotational movement of the paper guide table 4. The two main interlocking units 18 and the paper guide table 4 are in an interlocking relationship. The return spring force of the second set spring 15 applied to the main interlocking unit 18 becomes the driving force of the main interlocking unit 18.
[0018] The power transmission mechanism 16 will be described with reference to Figures 15 to 23. The power transmission mechanism 16 includes intermediate interlocking units 23 and 24. The intermediate interlocking bodies 23 and 24 are located inside the side frames 1a and 1b and on the side plates within the storage casing C. One intermediate interlocking body 23 (right side in Figure 20) and the other intermediate interlocking body 24 (left side) consist of an intermediate interlocking body section 24a with the same configuration as the intermediate interlocking body 23 at the front and an intermediate interlocking transmission body section 24b with a fan-shaped tooth section 24b1 at its rear end at the rear, and the intermediate interlocking body section and the intermediate interlocking transmission body section are integrated. The connecting holes 23a and 24a1, which are opened at the front ends of each intermediate interlocking body 23 and 24 and through which the front connecting shaft 25 passes, are formed in an oval shape. The front connecting shaft 25 is inserted through both connecting holes 23a and 24a1. The front ends of each intermediate interlocking body 23 and 24 are connected to each driven interlocking body 19 via the front connecting shaft 25. The rear ends of the intermediate interlocking transmission body portions 24b of the intermediate interlocking bodies 23 and 24, located on both sides inside the housing casing C, are connected by a rear connecting shaft 26. Each intermediate linkage member 23, 24 is rotatable around the front connecting shaft 25 in accordance with the vertical movement of each driven linkage member 19. Since the connecting holes 23a, 24a1 of each intermediate linkage member 23, 24 are oval in shape, they do not hinder the rotation of the intermediate linkage members. Of the intermediate interlocking members 23 and 24, the intermediate interlocking transmission member 24b of one of the intermediate interlocking members 24 has the function of transmitting the interlocking force received from the driven interlocking member 19 to the clutch means 17 (Figure 22). The function of the intermediate interlocking transmission unit 24b in transmitting the interlocking force to the clutch means 17 will now be explained. As shown in Figure 23, the sector-shaped teeth 24b1 of the intermediate interlocking transmission unit 24b mesh with the transmission gear 27. The transmission gear 27 is mounted on one end of a rotating shaft 28, which is supported by plates on both sides inside the housing casing C, and a ratchet engaging gear 30 is attached to the other end, with the gear 27 being pivotally mounted on both sides of the housing casing C. The transmission gear 27, which is meshed with the fan-shaped teeth 24b1, transmits the rotational force received from the intermediate interlocking transmission body 24b to the ratchet engaging gear 30 of the clutch means 17 (Figure 23).
[0019] The clutch mechanism 17 will be described with reference to Figures 22 to 26. The clutch mechanism 17 includes a ratchet engaging gear 30, a ratchet internal gear 31, and a ratchet 32. The ratchet engaging gear 30 meshes with a rotation transmission gear 29, which has a smaller diameter than the engaging gear. The ratchet engaging gear 30 is rotatable around the rotation axis 28. A ratchet internal gear 31, which has a smaller diameter than the ratchet engaging gear, is formed on the inner surface of the ratchet engaging gear 30, centered on the rotation axis 28. A ratchet 32 is axially mounted on the rotation axis 28 of the ratchet engaging gear 30, and each tooth 32a of the ratchet engages with the ratchet internal gear 31. Bearings 34 are positioned on the rotational direction side (clockwise in Figure 22) of each tooth 32a of the ratchet 32. Therefore, the bearings 34 prevent the ratchet 32 from rotating in the reverse direction (counterclockwise). As shown in Figure 26, the back of the ratchet engaging gear 30 is covered by a circular cover plate 35. An insertion hole 35a is provided in the center of the cover plate 35 for the rotating shaft 28 to pass through. The clutch mechanism 17 can select to transmit or disconnect the operating force from the paper feeding mechanism B to the paper feeding interlocking propulsion mechanism D.
[0020] The paper feeding interlocking propulsion mechanism section D (Figure 22), which is capable of transmitting or interrupting the interlocking force from the clutch means 17, will be described below. As shown in Figures 28 and 29, the paper feeding interlocking propulsion mechanism D has a feed drive roller 36 and a feed drive roller 37 that is driven by this drive roller. The feed drive roller 36 is positioned between the lower sides of the housing casing C. The feed drive roller 36 is formed from a horizontally elongated rod, with multiple roller sections 36a formed at intervals around its outer circumference. The ends of the roller shaft 36b at the axis of the feed drive roller 36 are rotatably supported on both sides of the housing casing C. A rotary transmission gear 29 is axially mounted on the shaft end of the roller shaft 36b on the inner surface side of the housing casing C on the lower side (Figure 28). The rotary transmission gear 29 meshes with a ratchet engagement gear 30. In addition, a portion of the outer circumference of the feed drive roller 36 is exposed below the housing casing C through the roller opening 10a at the bottom of the housing casing C and is positioned opposite to the roller opening 2b of the paper guide plate 2. The roller openings 2b and 10a have a width and length that does not hinder the rotation of the feed drive roller 36.
[0021] The feed-driven roller 37 will now be described. In Figures 22, 23, and 28, the feed-driven roller 37 is located below the lower paper guide plate 2 outside the storage casing C. Both ends of the roller shaft 37b of the feed-driven roller 37 are rotatably supported by the side frames 1a, 1b. The feed-driven roller 37 is formed from a horizontally elongated rod, with multiple roller sections 37a formed at intervals around its outer circumference. The feed-driven roller 37 is in contact with the feed-driven roller 36, which is located above and outside the bottom of the housing casing C. The diameter of the feed-driven roller 37 is smaller than that of the feed-driven roller 36 above it. The feed-driven roller 37 rotates in conjunction with the rotation of the feed-driven roller 36 with which it is in contact. The case where the feed-driven roller 37 rotates will be explained. When the paper P is set, as shown in Figure 10, the arm 6a of the first set spring 6 elastically contacts the roller shaft 37b of the feed-driven roller 37 with a predetermined spring force. When the paper is used, the paper guide table 4 rotates counterclockwise and the table holding shaft 5 pushes up the roller shaft 37b from below via the arm 6b, causing the roller portion 37a of the feed-driven roller 37 to come into strong contact with the roller portion 36a of the feed-driven roller 36. As a result, the feed-driven roller 37 rotates in tandem with the rotation of the feed-driven roller 36. When the feed-driven roller 36 and the feed-driven roller 37 are in strong contact with each other, the paper P is sandwiched between the feed-driven roller and the feed-driven roller, and as the feed-driven roller rotates clockwise, the feed-driven roller moves in its place, causing the paper P to be fed forward to the holder base A (Figure 1).
[0022] The process of feeding paper P, which is fed out by the joint operation of the feed-driven roller 36 and the feed-driven roller 37, will be explained. As the paper P is pulled from the paper roll R, the feed drive roller 36 rotates clockwise, causing the lower feed drive roller 37 to rotate counterclockwise in response, and the paper P is fed forward to the holder base A. The paper P is then guided between spacers 13, which are arranged side by side on the bottom surface of the storage casing C with a width sufficient for the paper to pass through, and through the gap d between the paper guide plate 2 and the paper guide table 4, and is guided out of the table's leading edge (left end side in Figure 1).
[0023] The paper cutting mechanism E, which cuts the paper P at a predetermined position as it is being fed forward from the holder base A, will be described with reference to Figures 18, 19, and 29-38. The paper cutting mechanism E includes a cutting plate 38 and a cutting action facilitator 43 for accelerating the cutting operation of the cutting plate. The cutting plate 38 will be explained with reference to Figures 29 to 33. The cutting plate 38 is positioned in the width direction (intersecting the left-right direction in Figure 30) so as to divide the storage casing C front to back. The cutting plate 38 is held in place at the top and bottom of the storage casing C. The cutting plate 38 consists of a plate-shaped paper cutting blade 39 and a pressing plate 40 that clamps the paper cutting blade from both the front and rear sides so that it can move up and down. The paper cutting blade 39 is formed in a plate shape, and its lower end edge has a saw-shaped cutting edge 39a. The front and rear pressing plates 40 have the same configuration, and a paper retainer 40a is formed at their lower ends. Elastic pieces 41 are fixed to the lower ends of both paper retainers 40a as needed, as shown in Figure 29, to enhance the paper-holding effect on the paper P. The cutting plate 38 has coil springs 42, which act as regulating springs, positioned on both sides in the width direction (left-right direction in Figure 30). Both coil springs 42 are housed in vertically elongated mounting holes 39b and 40b formed opposite the paper cutting blade 39 and the pressing plate 40, and the upper and lower ends of both coil springs are elastically in contact with the inner surfaces of the upper and lower ends of each mounting hole. The upper and lower ends of both coil springs 42 are fitted into positioning protrusions 39b1 and 40b1 that protrude opposite each other from the upper and lower ends of the mounting holes 39b and 40b, thus ensuring that the coil springs are housed in a stable state. The two coil springs 42 function as means of connecting and fixing the overlapping paper cutting blade 39 and the pressing plate 40. Of course, the coil springs 42 also have their original functions of suppressing the vertical movement of the cutting plate 38 and returning the paper cutting blade 39 to its original position. Furthermore, as shown in Figures 31 and 32, the paper cutting blade 39 and the pressing plate 40 that constitute the cutting plate 38 have grooves 39c and 40c formed on both sides in the width direction (left-right direction in Figures 31 and 32) of the upper center, cut downward from the upper end surface. The pressing groove 39c of the paper cutting blade 39 has the same width as the groove 40c of the pressing plate 40, but the groove 39c is shallower, while the groove 40c of the pressing plate is a vertically elongated sliding groove. In the paper cutting blade 39 and the pressing plate 40, vertically elongated rectangular guide holes 39d and 40d, of the same shape and length, are provided between the pressing groove 39c and the sliding groove 40c and the mounting holes 39b and 40b, along each mounting hole. The guide holes 39d and 40d face each other at the front and rear. Furthermore, the paper cutting blade 39 and the pressing plate 40 have openings 39e and 40e, which are vertically elongated but the same width as the openings, on the outside of the mounting holes 39b and 40b. The upper ends of both openings 39e and 40e face each other at the front and rear.
[0024] The cut-off action accelerator 43 will be described with reference to Figures 34 to 38. The cutting action facilitator 43 is positioned on the inner surface of the bottom of the storage casing C on the front side (left side in Figure 29) of the cutting plate 38, and has side plates 44 that are erected at intervals from the inner surface of the bottom in the left-right direction in Figure 35. A movable holder 45 is positioned between the two side plates 44 of the cutting action facilitator 43 so as to be able to move up and down. The movable holder 45 is assembled from side plate portions 45a adjacent to the inner surface of each side plate 44 and upper and lower horizontal plate portions 45b and 45c connecting the side plate portions. The movable holder 45 is also capable of moving up and down along a guide shaft 47 that is spaced apart between the side plate portions 45a. The guide shaft 47 rises from the bottom of the storage casing C and passes through the lower horizontal plate portion 45c and the upper horizontal plate portion 45b. As shown in Figure 35, a coil spring 46, which acts as a regulating spring, is wound around the guide shaft 47 in the portion between the lower horizontal plate portion 45c and the bottom of the storage casing C. The coil spring 46 applies an upward spring force to the movable holder 45 through the horizontal plate portion 45c. The movable holder 45 descends against the spring force of the coil spring 46, and once it has finished descending, the movable holder returns to its original position due to the repulsive force of the coil spring. In Figures 34 and 35, a pair of pressing sliders 48, spaced apart above the movable holder 45, are fixed to the horizontal plate portion 45b. The tips 48a of both pressing sliders 48 are mounted facing rearward. As shown in Figure 35, the two pressing sliders 48 are connected by a connecting shaft 49, with both ends passing through the side plate portion 45a and side plates 44, 44, and the shaft end is secured with a nut 50. Both ends of the connecting shaft 49 are inserted through wide, vertically elongated holes 44b in the side plates 44, and penetrate the side plate portion 45a (Figure 36). Furthermore, as shown in Figure 35, auxiliary pressing sliders 51 are positioned on both sides of the cut operation facilitator 43 located within the storage casing C. Guide shafts 52, which rise from the bottom of the storage casing C, pass through both auxiliary pressing sliders 51. Both auxiliary pressing sliders 51 are freely movable up and down relative to the guide shafts 52. To restrict the up and down movement of the auxiliary pressing sliders 51, a coil spring 53, which acts as a restricting spring, is wound around the portion of the guide shaft 52 between the lower surface of the auxiliary pressing slider and the bottom of the storage casing C. The coil spring 53 applies an upward spring force to the auxiliary pressing sliders 51. The auxiliary pressing sliders 51 descend against the spring force of the coil springs 53, and once they have finished descending, the auxiliary pressing sliders return to their original position due to the repulsive force of the coil springs (Figure 37). During the descent of the auxiliary pressing slider 51, the projection 51a moves downward within the vertically elongated opening 40e of the pressing plate 40 while pressing downward the lower end of the inner surface of the opening 39e of the paper cutting blade 39.
[0025] The relationship between the cutting plate 38 and the cutting action accelerator 43 will be explained with reference to Figures 29 to 35. The paper cutting blade 39 and the pressing plate 40, which overlap front to back, have opposing pressing grooves 39c and sliding grooves 40c, into which the tip 48a of the pressing slider 48 is inserted from the upper end. In addition, the sliding projections of the auxiliary pressing slider 51 are inserted into the openings 39e and 40e of the paper cutting blade 39 and the pressing plate 40. Furthermore, guide projections 44a formed on the lower part of the side end faces of each side plate 44 shown in Figures 34 and 35 are inserted into the guide holes 39d and 40d, respectively. Since each side plate 44 and the pressing plate 40 are fixed, the movement of the guide projections 44a is relative to the guide holes 39d and 40d in accordance with the movement of the paper cutting blade 39.
[0026] The cutting process using the cutting plate 38 will be explained. As shown in Figure 38(a), on the front side of the cutting plate 38, the front connecting shaft 25, which is positioned along the cutting plate as shown in Figures 34 and 35, is inserted through a vertically elongated narrow hole 44c (Figure 36) opened in one side plate 44 of the cutting action facilitator 43, and the movable holder 45 penetrates both side plate portions 45a in the width direction (left-right direction in Figure 35) and then penetrates the vertically elongated narrow hole in the other side plate. Therefore, as the front connecting shaft 25 moves up and down, the movable holder 45 and the pressing slider 48 move up and down against the spring force of the coil spring 46. The pressing slider 48 presses downward on the inner bottom surface of the pressing groove 39c of the paper cutting blade 39 by its up and down movement (Figure 31). This pressing causes the paper cutting blade 39 to descend against the spring force of the coil spring 42, protruding from the bottom surface of the storage casing C and enabling it to cut the paper P (Figure 19). Specifically, the cutting edge 39a of the paper cutting blade 39 protrudes downward from the small hole 10c at the bottom of the storage casing C and the small hole 2d of the paper guide plate 2, cutting the paper P from above while holding it down with the paper presser 40a {Figure 38(a)}. The elastic piece 41 on the lower surface of the paper presser 40a facilitates cutting. Furthermore, the vertical movement of the movable holder 45 is not hindered because the connecting shaft 49 can move up and down within the holes 44b of the side plates 44. The pressing slider 48 moves smoothly up and down due to the presence of the slide groove 40c and guide holes 39d and 40d. The movement of the guide projection 44a is relative to the guide holes 39d and 40d, so its movement is also smooth. The auxiliary pressing slider 51 moves smoothly up and down due to the presence of the guide hole 40d.
[0027] Once the paper cutting blade 39 has finished cutting the paper P, it instantly returns to its original position due to the spring force of the coil spring 42. After the user finishes cutting the paper P, the paper guide table 4 attempts to return to its original position due to the spring force of the second set spring 15. However, the speed at which the paper cutting blade 39 attempts to return to its original position due to the return spring force of the coil spring is faster than the speed at which the paper guide table returns. Therefore, as soon as the cutting of the paper P is finished, a new sheet of paper P has already been fed into the paper guide table 4, and the paper setting state is maintained.
[0028] Next, a method for using the paper holder according to this invention will be described. First, when the user grasps the leading edge of the paper P shown in Figure 1 (the standby state before use) and pulls it out to the left in Figure 1, the leading edge of the paper guide table 4, which is in the set state, is pushed downward. This causes the paper guide table to rotate counterclockwise around the table holding shaft 5 at its rear end, against the spring force of the first set spring 6, and the inclination angle of the paper guide table gradually increases. As a result, the hook 18a of the driving interlocking body 18 engages with the hook 19a of the driven interlocking body 19, which lowers the driven interlocking body and the front connecting shaft 25. Of the intermediate interlocking bodies 23 and 24 that receive driving force from the front connecting shaft, the intermediate interlocking body section 24a on one side transmits the interlocking force to the feed driving roller 36 from the clutch means 17 via the transmission gear 27 and the rotary transmission gear 29. As the mutually engaged main unit 18 and driven unit 19 descend, the front connecting shaft 25 also descends, causing the pressing slider 48 to descend along with the movable holder 45, and the cutting edge 39a of the paper cutting blade 39, which is being pressed downwards, to descend. As the paper guide table 4 rotates counterclockwise, the cutting edge 39a of the paper cutting blade 39 descends and cuts the paper P by piercing it in the width direction (Figures 19 and 38). At the moment of cutting, the paper cutting blade 39 instantly returns to its original position due to the repulsive force of the coil spring 42. Furthermore, the repulsive force of the coil spring 46 of the movable holder 45 is also added, further increasing the speed at which the paper cutting blade returns to its original position. Once the paper P has been dispensed, the paper guide table 4 returns to its original position (horizontal position). However, because the paper cutting blade 39 returns to its original position quickly even after the dispensed paper P has been cut, the feeding continues based on the joint action of the feed drive roller 36 and the feed driven roller 37, and the next sheet of paper is guided to the front of the paper guide table 4. Once the paper is fully extended, the spring action of the second set spring 15 is released, and the paper guide table 4 rotates clockwise in Figure 16, returning to its original position shown in Figure 15. During the process of the paper guide table 4 returning from the position shown in Figure 16 to its original position shown in Figure 15, the driving interlocking body 18 and the driven interlocking body 19, which are engaged with each other by hooks 18a and 19a, move upward as a single unit, and the front connecting shaft 25 is pushed up by the driven interlocking body, causing the front ends of the intermediate interlocking bodies 23 and 24 to rise and rotate clockwise. As a result, the intermediate interlocking transmission body 24b rotates counterclockwise, and the sector-shaped tooth portion 24b1 also rotates in the same direction, imparting a clockwise rotational force to the transmission gear 27 and the rotary transmission gear 29. Therefore, the ratchet engaging gear 30 and the ratchet 32 in the clutch means 17 attempt to rotate in the opposite direction to the original rotation direction, but the bearing 34 prevents the reverse rotation. This prevention interrupts the rotation of the feed driving roller 36. The paper feed drive roller 36 becomes unable to rotate in the paper feeding direction, and the paper drive roller returns to its standby position.
[0029] By using the elastic piece 41 on the underside of the paper presser 40a, the paper is held securely while cutting, making cutting easier and more reliable. Regarding the cutting plate 38, as shown in the example in Figure 30, if the paper cutting blade 39 is held between the pressing plates 40 on both sides and integrated using a coil spring 42, a cutting plate is formed in which the paper cutting blade and the pressing plates are easily joined, and the coil spring has a return function, thus simplifying the structure of the cutting plate. The upper and lower parts of the cutting plate 38 may also be held between a pair of retaining plates attached to the upper and lower surfaces of the storage casing C. [Explanation of Symbols]
