A paper holder configured to cut the paper with one hand includes a plate-shaped cutter member. A cutting blade is provided at the distal end of the cutter member, and a rotating shaft is provided at an intermediate portion between the distal end and the proximal end. The cutter member is pivotally attached to the paper holder via the rotating shaft so that the cutting blade is disposed on the path of feeding the paper. And when cutting the paper, by pressing the paper against the cutting blade, the cutter member rotates about the rotation shaft, the base end of the cutter member presses the paper, The paper can be cut with one hand.
In addition, the conventional paper holder is configured to use the force pressing against the cutting blade to cut the paper, rotate the cutter member, and press the paper at the base end of the cutter member. Since the force for pressing the paper at the proximal end is weak, the edge-shaped cutting blade slips during cutting, and the paper cannot be cut cleanly. For this reason, the conventional paper holder has a cutting blade with a serrated shape, improves the cutting ability of the cutting blade to the paper, and prevents the finger from touching the cutting blade with a safety cover from the outside. The safety cover is rotated with respect to the cutter member at the time of cutting, so that the cutting blade is exposed.

Insertion slits 25 are formed on the lower surfaces of the pair of left and right side plates 22A and 22B. Depending on the direction in which the holder body 11 is fixed to the support column 1, one of the left and right side plates 22 </ b> A and 22 </ b> B is inserted into the insertion slit 25, and the column 14 is inserted into the selected insertion slit 25. By inserting the insertion piece 14 </ b> B, the frame body 21 is mounted and fixed to the mounting seat 14 </ b> A of the column 14.
A wall portion 26 is provided inside the frame body 21. Further, by arranging the wall portion 26 so that the rear edge thereof is separated from the back cover 24, a feeding port 27 is provided inside the frame body 21. Further, a through hole 28 is formed at the front end of the wall portion 26 so as to penetrate the wall portion 25 in the thickness direction. Then, the paper P drawn out from the roll paper is inserted from below into the frame body 21 on the inner surface side of the wall portion 26, and is fed out on the outer surface of the wall portion 26 through the feeding outlet 27. And it is comprised so that it may reach on the through-hole 28 (refer FIGS. 5-8).

A movable blade 31 is provided inside the frame body 21. The movable blade 31 is formed in a substantially plate shape in plan view, and a cutting blade 32 is erected at the tip of the movable blade 31 toward a through hole 28 provided at the tip of the wall portion 25. The cutting blade 32 has a sawtooth shape, so that the cutting force on the paper P is improved.
A rotating shaft 33 is provided at the proximal end of the movable blade 31. The movable blade 31 is configured to be rotatable in the vertical direction inside the frame body 21 by being pivotally attached to the inside of the frame body 21 via the rotation shaft 33. When the movable blade 31 is rotated in the vertical direction, the cutting blade 32 is in a standby position (see FIG. 3B) drawn into the frame body 21 from the through hole 28 and the through hole. It is comprised so that it can displace between two positions of the cutting position (refer FIG. 8) which appeared on the outer surface of the said wall part 26 from 28. FIG.
At the base end of the movable blade 31, an operation unit 34 is extended from the circumferential surface of the rotation shaft 33 toward the rear, which is the direction of the back cover 24. A first spring member 35, which is a biasing means, is disposed on the lower surface of the operation unit 34. The front end of the first spring member 35 is in contact with the lower surface of the operation portion 34, and the operation portion 34 is always urged upward. When the operation portion 34 is urged by the first spring member 35, the movable blade 31 is always urged to rotate downward about the rotation shaft 33. As a result, cutting is performed. The blade 32 is held at the standby position.

Inside the frame body 21, a cam member 36 is disposed between the operation portion 34 inserted from the base end of the movable blade 31 and the back cover 24. The cam member 36 is formed in a substantially shaft shape, and is attached to the inside of the frame body 21 via a shaft 37 so as to be rotatable about the shaft 37.
At the upper part of the peripheral surface of the cam member 36, a contact portion 38 is provided so as to be disposed inside the feed outlet 27. The contact portion 38 is formed in a fan shape in a side view and has a contact surface 38A that is a curved surface. The abutting surface 38A is configured to abut on the paper P when being fed through the feeding outlet 27 (see FIG. 5). When the paper P is fed out, by pulling the paper P, the abutting portion 38 abutted on the paper P is pushed in the pulling direction, and the cam member 36 is rotated. (See FIGS. 6 to 8). Further, by making the contact surface 38A a curved surface, it is possible to prevent the paper P from being caught by the corresponding contact portion 38 when being brought into contact with the contact portion 38 and being unable to be fed out.

A flat pressing portion 39 is formed at a position facing the back cover 24 at the lower portion of the peripheral surface of the cam member 36. A convex portion 40 projects from the inner surface of the back cover 24, which is the inner surface of the frame body 21, inside the frame body 21 so as to be in a position corresponding to the pressing portion 39. The pressing portion 39 and the convex portion 40 are provided so as to sandwich and fix the paper P at the time of cutting (see FIG. 8). That is, the pressing portion 39 approaches the convex portion 40 when the cam member 36 rotates, and presses the paper P against the convex portion 40, so that the paper P is between the convex portion 40. To fix.
The convex portion 40 has a curved front end surface, and by reducing the contact area when contacting the pressing portion 39 with the paper P interposed therebetween, the pressing portion 39 is formed on the convex portion 40. The pressing force of the paper P is concentrated on a small area so that the pressing force can be suitably exhibited. A pair of upper and lower tension bars 41 are provided between the cam member 36 and the back cover 24 so as to sandwich the convex portion 40. The pair of upper and lower tension bars 41 is for suppressing the slack of the paper P between them. When the paper P is clamped between the pressing portion 39 and the convex portion 40, the pressing bar 41 is pressed. The force that the portion 39 presses the paper P against the convex portion 40 is prevented from being consumed unnecessarily by the slackness of the paper P.

A pressing portion 42 projects from the front portion of the circumferential surface of the cam member 36 so as to be positioned above the operation portion 34 that is inserted from the base end of the movable blade 31. The pressing portion 42 is configured to come into contact with the operation portion 34 when the cam member 36 is rotated and to press the operation portion 34 downward. The pressing unit 42 rotates the movable blade 31 by pressing the operation unit 34 and displaces the cutting blade 32 from the standby position to the cutting position. Further, while the operation portion 34 is pressed downward by the pressing portion 42, the cutting blade 32 is held at the cutting position.
On the lower surface of the cam member 36, a second spring member 43 as an urging means is disposed. The tip of the second spring member 43 is in contact with the lower surface of the cam member 36, the cam member 36 is in the upward direction, that is, the pressing portion 42 is separated from the operation portion 34, and the convex portion The pressing portion 39 is always urged away from the portion 40. Therefore, the cam member 36 is urged by the second spring member 43 to stop the pulling of the paper P when the paper P is fed out, so that the pressing of the operation portion 34 is released, and the pressing portion The paper P is fixed by 39.

The attachment of the paper P to the cutting mechanism 12 will be described.
When the paper P is loaded, as shown in FIG. 4, the back cover 24 is opened, and the paper P drawn from the roll paper is inserted into the frame body 21 from below, and the leading end of the paper P is fed from the outlet 27. Then, the rear cover 24 is closed. Then, as shown in FIG. 5, the convex portion 40 presses between the pair of tension bars 41 to apply tension to the paper P, thereby preventing the paper P from falling off from the inside of the frame body 21 and cutting. Attachment of the paper P to the mechanism part 12 is completed. Further, after the mounting is completed, the paper P is fed out from the feeding port 27 by a predetermined amount so as to be used immediately when desired, and is placed and held on the outer surface of the wall portion 26.

The cutting of the paper P using the cutting mechanism unit 12 will be described.
At the time of cutting the paper P, as shown in FIG. 6, first, the paper P placed and held on the outer surface of the wall portion 26 is picked up with one hand and pulled straight upward as it is. At this time, the paper P is merely slidably brought into contact with the contact surface 38A of the cam member 36, and the cam member 36 is not rotated.
When the delivery of the paper P reaches a desired amount, when the one hand holding the paper P is lowered to cut the paper P, the paper P is brought into contact with the cam member 36 via the contact surface 38A as shown in FIG. The cam member 36 starts to rotate against the urging force of the second spring member 43. Further, as the cam member 36 starts to rotate, the pressing portion 42 presses the operation portion 34, so that the movable blade 31 starts to rotate against the urging force of the first spring member 35,
The cutting blade 32 starts to move from the standby position to the cutting position.
As shown in FIG. 8, until the paper P contacts the cutting blade 32, the cam member 36 presses the paper P against the convex portion 40 provided on the inner surface of the frame body 21 by the pressing portion 39. The paper P is fixed. Further, the movable blade 31 in a state where the operation portion 34 is pressed by the pressing portion 42 of the cam member 36 is held in a state where the cutting blade 32 is turned to the cutting position. The paper P is cut by pressing the paper P against the cutting blade 32 held at the cutting position.
After the paper P is cut, the force pulling with one hand is not applied to the paper P, so that the cam member 36 is quickly rotated to the original position by the urging force of the second spring member 43 as shown in FIG. The movable blade 31 is quickly rotated to the original position by the urging force of the first spring member 35, and the cutting blade 32 is moved from the cutting position to the standby position. The leading end portion of the paper P is placed and held on the outer surface of the wall portion 26.

The cutting operation of the paper P using the cutting mechanism unit 12 can be completed with a very simple and small operation of picking and pulling the paper P with one hand. That is, while the paper P is being pulled to be cut, the paper P is pressed against the convex portion 40 and fixed by the pressing portion 39, so that the pulling force can be effectively transmitted to the paper P, and further the cutting blade 32. Is held at the cutting position, so that the cutting blade 32 does not move or escape during cutting. Therefore, the paper P is cut cleanly and suitably, and the paper P is pinched so as to follow the cutting blade 32. There is no need to move your hand.
Further, since the cam member 36 is rotated by a pulling operation to cut the paper P, the pulling force is not applied to the paper P after the cutting operation is completed, and the cam member 36 is pressed by the pressing portion 42 of the cam member 36. Since the pressing of the operation unit 34 is released, the cutting blade 32 quickly moves to the standby position. In other words, the cutting blade 32 is held at the standby position except when it is pulled to cut the paper P, so that it is not exposed to the outside, so that the finger does not touch the cutting blade 32 by mistake. . As a result, the cutting mechanism unit 12 has very high safety without a finger touching the cutting blade 32 by mistake.

The present invention is not limited to the configuration of the above-described embodiment, and the configuration of the embodiment may be changed as follows.
The cutting mechanism 12 is not limited to being arranged on the upper part of the roll paper supported by the holder main body 11, but may be arranged on the front part or the lower part of the roll paper.
The convex portion 40 may be omitted, and the pressing portion 39 may be configured to directly press the paper P against the inner surface of the frame body 21 such as the inner surface of the back cover 24.
You may abbreviate | omit the said 1st spring member 35 which is a biasing means. Further, instead of the urging means, a weight may be attached to the lower surface of the movable blade 31 so that the cutting blade 32 is always held at the standby position except during cutting. Similarly, the second spring member 43, which is an urging means for urging the cam member 36, may be omitted, or the cam member 36 may be pressed by attaching a weight to the rear side of the lower surface of the cam member 36. The cam member 36 may be biased in a direction in which the pressing of the operation unit 34 by the unit 42 is released.

  In the paper holder of the present invention, it has sufficient safety and can easily and suitably cut the paper with one hand. There is industrial applicability for the elderly and the elderly.
