The present invention is like the automation of business tasks equipped on copiers, printers, fax machines, etc. (〇 A) Paper material cutting device used by the machine. In particular, Yu Yu improved the paper cutter cutting device to improve the quietness and stable cutting. [Conventional Technology] For example, a paper cutting machine mounted on a copier, printer, facsimile, or other office automation machine is a paper cutter that rotates, as described in Japanese Patent Publication No. 5B 24466. A rotary paper cutting device that is connected to a fixed knife and cuts, or a sliding device that cuts and cuts a cross by crimping a movable knife that moves up and down in a fixed force as described in Japanese Patent Sho 58-37594. Type paper cutting device, but these cutting devices all need to drive a cutter with a length equivalent to the cutting width, so that when the cutting width is widened, the driving force is relatively small, which is not conducive to miniaturization. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. Relatively, known are cutter moving type cutting devices, such as Japanese Shikai Hei 4-128195, etc., which slide and slide circular knives or knife-shaped knives. A cutting device that moves and cuts with a fixed knife, or, as described in Japanese Patent Application Laid-Open No. 7-52Q85, etc., moves a knife holder having two circular knives that are crimped to each other and moves a knife that cuts paper. Type cutting device. These cutter-moving cutting devices have lower driving power and smaller cutting width restrictions than smaller rotary or sliding small paper cutting devices. This is advantageous. In particular, the latter roller-type cutting device with a two-country-shaped knife, because of the long fixed knife that is not used, it is easy to cooperate with the cutting of wide paper. The size of the paper is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 490370 Economy Printed by the Consumer Standards Cooperative of the Ministry of Standards, Ministry of Standards, A7 and B7 5. Changes in the invention description (>) make it more conducive to small size and weight. The cutting tool moving means of the cutting tool moving type cutting device is a moving device that reciprocates by pulling the tool holder by a mesh wire or a toothed belt. However, the cutting device changes the direction of the cutting tool at the terminal part. The seat will generate a chirping sound due to the inertia and conflict with the stopper. Therefore, it is not ideal for a device equipped with a silent work automation machine. Therefore, a thread-driven moving device is used which screwes the male thread of the shaft body to the female thread provided on the tool holder, and reciprocates the tool holder by the positive and negative rotation of the shaft. For this type of thread-driven moving device, it is necessary to set the forward and reverse rotation of the drive mechanism such as the motor when the tool holder is reciprocated when the cutter head is reciprocated. As for the roller-type paper cutting device, the cutting end is usually cut freely without being fixed. After cutting, it is dropped and collected on a tray. However, it is especially not available on the top. The roller-type paper cutting device with a free set structure where the cut paper is placed on the support and can be cut by using a guide member. The driving part of the roller-type paper cutting device is located under the support, causing the moving tool holder to reciprocate. When moving, the cut and discharged paper will interfere with the cutter holder and mess up the collected paper. In order to prevent this problem, there is a discharge structure 01, the cone forcibly discharges the cut end of the cut paper material away from the cutting point where the fixed knife or the cutting knife and the circular knife slide. It is well known to excrete the stomach (for example, as disclosed in Japanese Patent Laid-Open No. 6-134692 or Tokaikai No. 7-5208 5 [Problems to be solved] This paper size applies the Chinese National Standard (CNS) A4 specification (210X297) Li) (Please read the notes on the back before filling in this page)

490370 A7 B7____ 5. Description of the invention (>) However, the above-mentioned conventional screw-driven mobile device must rely on the forward and reverse conversion mechanism of the limit switch or its control circuit, resulting in an increase in the number of parts and complexity, which is not conducive to the requirements of small size and low cost. . In addition, in the case of office automation machines, there is an urgent need for better quietness in the operation of the shut-off device. In view of this, in order to make the cutting blade reciprocate in the width direction, the inventor has used a spiral-shaped guide path in which the directions are reversed to each other and connected at the end of the reciprocating direction to form a continuous shaft. And a moving mechanism that moves a tool holder to the spiral guide path. However, when using such a car body which has a spiral guide path that is reversed from each other to avoid false, a loud voice will occur, which makes it unsuitable for paper used in fax machines, such as fax machines, and other tasks. New problems with cutting devices. In addition, as for the paper material discharge structure used in the conventional roller-type paper cutting device, the cut end image of the paper material is forced out. Therefore, the cut end of the paper material is still uneven. The wavy problem exists. Printed by the Consumers' Cooperative of the Central Bureau of Standards, Ministry of Economic Affairs (please read the precautions on the back before filling out this page). In view of this, in order to solve the above problems, the purpose of the present invention is to provide a cutting blade that can easily be used in the width direction of the paper material. It is a paper cutting device that can be used as a reciprocating lotus and has the quietness that can be loaded on the office work automation machine, and can prevent the cutting surface from wavy, and can be cut stably. [Means of Solving the Problem] As a result of research on noise by the present inventors, if a spiral guide path with upper and lower directions opposite to each other is formed on the outer diameter of the shaft material, there must be a spiral crossing as shown by 2e in FIG. 3 If the point exists, then the axis of rotation is used. When the moving body moves, it is found that the existence of the intersection point causes the work.

Description of the invention (4) One of the reasons for the rustling metal murmur on automated machines. Then, the inventor focused on preventing such a rattling golden murmur if a metal body is formed of a synthetic resin, and finally found out that the spiral guide path and the engagement with the guide path are formed by a resin molding method. The resin is effective and completes the present invention. In order to achieve the above object, in the paper material cutting device of the present invention, in a paper material cutting device that cuts a paper material by moving a cutting blade in a forward direction and a double direction, it is required to have The helical guide path is provided with a moving body engaged with a coupling member of the helical guide path, a cutting blade supported by the movable body, and a driving means for rotating the car body; and the helical guide path傺 It consists of the rotation of the forward direction that forms the direction of the forward direction, and the spiral of the double direction that forms the direction of the secondary direction. The forward direction "Spin and the rearward direction circulate you into two revolving paths, and at least make the forward The one-way directional rotation and the two-way directional rotation are connected to each other to form a continuous ore-shaped guideway formed by resin molding. The coupling member 僳 is formed by resin molding and is rotatably supported by the moving body. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economics In other words, the paper cutting device of the present invention has a helical guide path of a shaft body rotated by a driving means and a rotatable coupling supported on a mobile body engaged with the shaft. The member 僳 is formed by resin molding. Therefore, when the moving body supporting the cutting knife is moved and cut, it is engaged with the case where the moving body is moved by meshing with a car body made of gold and a metal joint. Than, it is not so quiet as to produce a metallic noise. This is what the present invention is intended to do. If this spiral guide is formed by the resin molding method, the paper size is not applicable to the Chinese National Standard (CNS) A4 (210X297 mm). 490370 A7 B7 is easy to form, which can reduce costs and reduce wear without the need. . In this case, if the screw is a spiral groove with an enlarged enlarged cross section, the guide member of the coupling member can be smoothly guided in the continuous guide groove. Since at least one end of the screw in the direction of the road is connected to each other, The reversing of the leading and turning driving means can also convert the road and the complex road to further quietness and streamline the structure. It is best to spiral the direction of the road at its two ends to form endless results without having to reverse the rotating driving means. Succession moves towards. That is, the endless guide path is formed by screwing the ground in the direction of Kushiro. The guide path of the axis is transformed into a linear motion of the moving body. When the point moves toward the end point and the end point is converted into a compound road, the moving body It is like going in one stroke at a time, and it is possible to switch the direction of the link road and the direction of the double road without reversing the rotation driving means. Printed by the Employees' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of the invention (factory) Only the spiral-shaped guide path is subject to other lubrication measures. The spiral-shaped guide path can be formed on the bottom of the intersection, making the quietness better. The spin and the double direction spiral, so there is no need to make the spin direction. In addition, in order to guide the path spirally and 愎 (end 1 ess) in the direction of the road, one or both ends of the square rotation of the reciprocating path are rotated mutually. The spiral tool is used to move from the direction of the road to the direction of the spiral and the road is in the direction of the double path. The moving direction of the movable mounting body is as described above. As long as the direction of the knife is reversed to prevent the moving body from driving due to inertia and other parts, the driving means required is relative to the shaft. Please read the back first.

The spiral shaft body can be rotated in one direction to implement the movement in the cut-off direction. Therefore, it is possible to provide a conversion sound at the end of the reciprocating path. The collision sound with the stopper is small, quiet, and no direction. Switching device of switching mechanism. The pitch of the spiral in the direction of the road and the paper size of the spiral in the direction of the road apply the Chinese National Standard (CNS) A4 (210X 297 mm) 49 ^ 0370 A7 B7 V. Description of the invention (b) If the pitch of the spiral is large, then It is not necessary to change the rotation speed of the shaft body to increase the speed in the return direction, so that the cutting knife quickly returns to the standby position. This kind of configuration is effective for situations where the double circuit is not cut off and the double circuit load is small. The coupling member of the moving body is preferably provided with an induction portion that slides on the spiral guide path of the shaft body to convey the driving force required for the reciprocating movement of the moving body. The guide road junction surface of the shaft body of the guide road with a longer road width is more than 1/3 of the circumference of the shaft. In other words, since the spiral guide path of the axial body of the present invention is formed as a revolving blue image of the spirals in the forward direction and the double direction, there is an intersection of the reciprocating path spirals, as shown in Fig. 3 2e. Therefore, when the moving body supporting the cutting blade passes through this intersection, the joint will shake and conflict with the corners and corners of the intersection, making a squeaking sound. If the load is large, the joint will deviate from the normal guide path. Yu. On the other hand, as in the method of the present invention, if the coupling member is provided with the above-mentioned induction portion, the shaking of the coupling portion will be reduced, which can not only prevent the noise of the crossing portion, but also prevent the coupling member from being off-line, making it stable. Moveable. Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the note ^ V on the back before filling this page). In addition, if the induction department has a contact surface that greatly exceeds the half-circle shaft, the direction of the terminal in the reciprocating direction will be changed. Difficulties occur, so in order to make the reciprocating movement smooth and quiet, it is better that the induction portion has a contact surface of the guide path that is shorter than the half circle of the spiral and can cover more than 1/3 of the circle of the figure. Furthermore, in order to more reliably prevent the coupling member at the crossing portion of the loop from moving, the coupling member having a double-fork portion that slides in engagement with the spiral guide path and has rotation Ziru-8-This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) 70 03 49 A7 B7 V. Description of the invention (7) (Please read the precautions on the back before filling this page) A fork-shaped induction member of a handle of the moving body, and a biasing means for pressing the induction member toward the spiral guide path. In this way, when the moving body switches directions at both ends of the helical guide path, the fork portion engaged with the helical guide path will rotate with its handle as the axis to follow the guide path, so the reciprocating direction change at the terminal portion can be smoothly get on. In addition, the induction member is moved in a state of being pushed toward the spiral guide path by a boosting means. Therefore, it can faithfully move along the guide path, making it possible to more reliably prevent phenomena such as off-line or abnormal sound. The driving means for rotationally driving the shaft is preferably composed of a drive motor and a helical gear that can transmit the rotation of the drive motor to the shaft. The contact between the teeth is smooth. , Reduce the noise generated by the gear is lower than the linear tooth _. For Gu Lianyu's thrust and quietness, the helix angle of the helical gear is preferably set in the range of 10 to 30 degrees. The paper cutting device of the present invention has the following features: a guide rail with a hollow section extending in the direction of the reciprocating path, and the guide rail is arranged in the hollow

I The shaft body in the cross section printed by the staff consumer cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, and a moving cymbal, the moving body is provided with a sliding guide that engages with the shaft pus spiral guide and slides on the inside of the hollow section of the guide road unit. In this way, if the shaft body is arranged in the guide rail of the hollow section, the rotating part will not be exposed, which is not only safe but also conducive to miniaturization. The sliding part of the moving body is driven by sliding on the inner surface of the guide rail. Therefore, the upper surface of the guide rail can be used as the placement surface of the cut paper when cutting, so that it is easy to configure to place only the cut paper on the guide rail. The free positioning structure can be cut. This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 490370 A7 B7 V. Description of the invention (Chinese) It is also best to set a first induction surface after the moving direction of the moving body is cut off It is used to induce the cutting end of the cut paper material by pressing it downward from the cutting point. A second induction surface is formed like a conical surface or a cone-like approximate surface with the cutting point as the vertex. The broken end is induced while being discharged while being rounded, and a third induction surface is used to induce the release of the cut end of the round to the downstream side (hereinafter referred to as the downstream side) of the paper feed direction. The above structure is not limited by the shape of the paper material to be cut, but it is suitable for situations where the cut end will bend downward due to the inherent curling habit of the paper material. For example, roll paper materials such as thermal paper used in facsimile machines have a roll habit. In this case, the cut end of the cut and separated paper material will be wiped down by the first induction surface, and at the same time, As shown in FIG. 15, while being bent due to the roll habit of the roll paper, it is induced downward along the conical surface of the second induction surface or the approximate surface of the national cone, and then released through the third induction surface. Down at the downstream. Thereby, the cut paper material can smoothly leave the cutting point, so the paper material will not be wavy, which can prevent the occurrence of non-entangled cutting sounds caused by undulating waves and increase the quietness and can Perform a stable cut.

According to the above structure, as soon as the shaft body 1 rotates, the inducer 2 (1 fork portion 20a slides along the spiral groove of the guide path 2 and when it reaches the end of the guide path 2 the inducer 0 20 will halve along the endless guide path 2 Rotation, so that the moving body can smoothly move from the forward path to the double path. Because the fork portion 20a exaggerates the guide path 2 and is pressed by the leaf spring 21 to rotate easily, it does not cross the reciprocating path of the guide path 2. When the line is off-line or the like, the noise is also less. The gear 13 is fixed to the end of the side of the inverted plate 12 of the shaft body 1. The gear 13 meshes with the pinion 15 of the stirrup 14 to constitute a driving means to transmit the driving force to the shaft. Body 1. The gear 13 and the pinion 15 are helical gears with a helix angle of 15 ° made of resin molding. Based on the viewpoint of rales and shaft thrust, the helix angle of the helical gear is preferably between 10 degrees and 3 Between 0 degrees.

At this time, the first circular blade 5a is driven by the turbidity roller 7 to rotate its peripheral blade while moving in the direction of ingesting the cut paper, and the first circular blade is rotating. The paper material (not shown) placed on the hollow 3 is cut between 5 a and the second disc blade 5 b. When the moving body 4 reaches the end in the traveling direction located at the right end in FIG. 2, the cutting of the paper material ends. After the paper material is cut, when the shaft body 1 is further wound and rotated, the inducing member 20 follows the curvature change of the guide path 2 and spirally switches from the forward direction to the return direction at the end of the forward direction. The inducing member 20 moving in the direction of the arrow a shown in 箸 圔 3 will turn to the direction of the arrow b from the terminal portion, and then turn into the direction of the arrow C, and then turn to the direction of the double path of the arrow d. Thereby, the force returning the direction of the path is applied to the induction member 20 to move the moving body 4 in the direction of the return path. The movement of the helical terminal mite 4 in the direction of Kushiro is the same as that when the induction member 20 reaches the terminal in the direction of the road. This time, the spiral from the double-way direction is changed to the direction of the road. In this way, when the moving body 4 changes direction at the terminal portion, the induction member 20 is rotatably supported by the sliding portion 41 of the moving body 4 with its handle portion 10b, and the fork portion 20a can follow the spiral of the direction to be changed.

This paper size applies to Chinese National Standard (CNS) A4 specification (21 × 297 mm) 490370 A7 B7 V. Description of the invention () The spiral guide path can be continuously reversed, making the moving body at the terminal in the forward direction or the terminal in the dual direction The chirps caused by the conflict will not occur, and the quietness is also superior. In addition, even if the rotation direction of the drive source is wrong, the lotus in the forward direction and the reverse direction is still feasible, which can prevent accidents such as wrong motor polarity and motor damage due to overheating. If the spiral of the guide road is made to make the return path pitch longer than the return path pitch, when the return path is not cut off, the moving time of the return path with less load can be shortened, thereby shortening the cycle time of one cut. In addition, if the guide path is made into two or more side-by-side grooves, and two or more disengageable engaging portions are provided on the moving skeleton, the abrasion of the guide path groove can be reduced. Furthermore, the helical guide path and the coupling member of the shaft body are resinized, and the use of helical gears in the drive bar can reduce the voice by more than 10%. The resin-forming method can also be used to form the spiral guide path. Therefore, it is possible to manufacture the guide path at a low cost. If the guide path is formed into a groove with an enlarged enlarged cross-section, not only the mold release property during resin molding can be improved, Continuous guide grooves are formed on the bottom surface of the crossing point, which improves the quietness.
