Description

Paper cutting machine Technical field

 The present invention relates to a paper cutting machine for mainly cutting paper. Background art

2. Description of the Related Art Conventionally, a paper trimming device for cutting paper or the like is known. Among them, there is a type in which the sides of the paper are aligned using a guide body at the time of cutting in order to cut the paper accurately. In this paper cutting machine, the guide body extends in a direction perpendicular to the cutting direction. It is also equipped with scales so that it can be used as a scale. However, in order to enhance the transportability and the storage capacity of the paper cutting machine, it is desirable that the guide body is configured as a movable repositionable measuring element so that it can be stored in the main body of the paper cutting machine. For example, U.S. Design Patent No. 3,198,040, Design Registration No. 0,83,181, Japanese Utility Model Publication No. 7-815, and Japanese Patent Publication No. 7-8155, In the disclosed paper cutting machine, the guide body is housed in the main body when housed, and the guide body can be pulled out of the main body when unfolded. However, in these prior arts, the movement of the guide body is composed of two movements: a turning movement with respect to the main body and a vertical movement with respect to the main body. For this reason, there were cases where the guide body could not be moved quickly. Specifically, as described in Japanese Utility Model Publication No. 7-8154 and Japanese Utility Model Publication No. 7-81555, a guide is required to move the guide body 55 to the deployed position. After the body 55 is turned 90 degrees from the inside of the main body 1, the locking projection 63 of the guide body 55 is pressed into the stopper 50 of the main body 1 vertically by a predetermined force. Then, in order to move the guide body 5 5 in the accommodation position, after issuing pull the locking protrusion 6 3 of the guide member 5 5 the stopper member ⁵ 0 of the main body 1 in the vertical direction with a predetermined force, the guide body 5 5 is turned in the opposite direction and housed in the main body 1. Thus, in these prior arts, since the guide body 55 is moved in a two-stage manner, the operation of the guide body 55 is troublesome. In addition to the stopper body 50 and the locking projection 6 3, this turning mechanism has a guide long groove 52, a rotation center shaft 53, a small diameter projection 54, a large diameter projection 64, a sliding long groove 65, and a guide. Equipped with a long groove 66 and a disc spring 69, etc., the processing was troublesome. Further, the guide body 55 requires a predetermined force to move, and it may be difficult for a small child to use the guide body 55. Furthermore, if an excessive force is applied to the guide body, there is a possibility that the small parts constituting the turning mechanism may be damaged. Further, in these prior arts, a rail (scale body) 23 to which the cutter 35 is slidably mounted is pivotally supported in a hinge shape so as to be able to rotate upward with respect to the body 1. When the paper cutting machine is used, the rail 23 is turned upward to position the paper below the rail 23. Therefore, if the cutter 35 was accidentally protruded from the lifted cutter body (slider) 26, the cutter 35 was exposed and might touch the hand. Also, when the rail was moved up and down, the paper was sometimes displaced. Disclosure of the invention

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a simpler configuration of a guide body turning mechanism so as to achieve a reduction in the size of a paper cutting machine and further improve transportability and operability. It is another object of the present invention to provide a paper cutting machine that can easily switch between a deployed position and a stored position of a guide body. However, the rail on which the cutter is slidably mounted shall be mounted so that it cannot rotate upward with respect to the main body of the paper cutting machine, so that the cutter will not accidentally touch the hand during operation. In order to achieve the above object, according to the present invention, as described in claim 1, a main body, a rail mounted on the main body by being urged upward with respect to the main body, and slidably movable on the rail. A paper cutting machine comprising a slider to be mounted and a cutter to be mounted on the slider, wherein one end of the paper cutting machine is hingedly connected to the main body, and the other end is a development position perpendicular to the cutting direction. And can be swiveled between the storage position stored in the main body And a guide body.

 In this configuration, by attaching both ends of the rail to the main body of the paper cutting machine, the cutter is prevented from accidentally touching the hand during operation, and the swivel mechanism of the guide body is simply configured and simplified. In addition, it is possible to provide a paper cutting machine for switching the deployment position and the accommodation position of the guide body.

 Furthermore, the invention is characterized by what is stated in the other claims. Hereinafter, a paper cutting machine according to a preferred embodiment of the present invention will be described with reference to the attached drawings. BRIEF DESCRIPTION OF THE FIGURES

1 to 7 show a paper cutting machine 100 according to an embodiment of the present invention. The paper cutting machine 100 has at least the main body 10 and both ends can be attached to the main body 10 A rail 20, a slider 30 slidably mounted on the rail 20, a cutter mounted on the slider 30, and a guide body 40 movably mounted on the main body. As shown in these drawings, the paper cutting machine 100 according to the embodiment of the present invention is configured so as not to take up too much installation space, and enhances transportability and accommodation. The main body 10 can be formed in any shape, but is preferably formed in a substantially plate-like shape that extends elongated along the cutting direction, as shown in FIGS. At this time, as shown in the figure, a horizontal base 11 is provided on the upper surface of the main body 10. In addition, steps 12 with height differences are provided on both sides of the base 11. The step 12 is provided perpendicular to the cutting direction so that the paper on the base 11 can be aligned from the side at the time of cutting. Further, as shown in FIG. 2, a scale 13 is provided on the base 11 along the step 12 so that the width of the sheet can be measured at the time of cutting. Further, preferably, as shown in FIG. 3, a plurality of rubber legs 14 are appropriately provided on the back surface of the main body 10 so that the main body 10 does not easily slip when used on a desk. So that the base 11 is parallel to the top of the desk. As shown in FIG. 1, the rail 20 is formed so as to extend linearly along the longitudinal direction of the main body 10, and is located substantially in the center of the main body 10 along the longitudinal direction of the main body. . As is clear from FIGS. 4 and 5, both ends 22 of the rail 20 can be attached to the main body 10. However, both ends 22 of the rail 20 have a clearance for paper insertion with respect to the main body 10 and are mounted in a state of being urged upward. Preferably, both ends 22 are provided as described later. It can be mounted up and down with respect to 10. For this reason, the paper is inserted from the gap between the bottom surface of the rail 20 and the top surface of the base 11. In this way, the rail 20 is mounted so that it cannot rotate upward relative to the body 10 as in the prior art, so that the cutter does not accidentally touch the hand during operation. Reference numeral 15 denotes a power sheet, which indicates that a scratch-resistant cutter sheet 15 is provided on the base 11 directly below the power sheet. The cutter sheet 15 extends parallel to the rail 20 and protects the cutter when cutting. This cutter 0

—Grooves 16 may be formed on both sides of the door 15 to make it easier to grasp the end of the power sheet 15 so that it can be easily mounted or replaced. A slider 30 is mounted on the rail 20 so as to be slidable between both ends 22. The slider 30 can be formed in any shape, but preferably, the slider 30 is easily gripped with a finger during use. For example, as shown in FIGS. 6A and 6B, a concave portion 32 is formed on the back surface such that a portion 31 directly above the slider 30 is convex. A cutter is provided inside the slider 30 toward the base 11. The mounting method of the cutter is arbitrary. For example, as shown in FIG. 1, a detachable operation unit 33 is provided on the front of the slider 30, and according to the attachment / detachment of the operation unit 33, the cutter is mounted. Make it removable. Incidentally, the attached drawing does not show the internal structure of the slider 30 and the cutter mounted inside the slider 30. This means that the slider 30 and the cutter are configured as is known to those skilled in the art, for example, as disclosed in U.S. Pat. No. 5,671,647. It is just that. However, preferably, a rotary blade is mounted as a cutter in order to prevent sideways movement at the time of cutting and to reduce cutting resistance. In this case, the type of rotary blade used is not limited to a straight blade. For example, replacement blades such as a perforated blade that cuts in a dashed line shape, a streaked blade that leaves only streaks on paper, and a designed blade that cuts in various patterns may be prepared. Further, it is possible to use a cutter such as a knife that performs a cutting function without rotating. As described above, the Reynole 20 can be attached at both ends 22 to the main body 10. At this time, the rail 20 is attached to the main body 10 while being urged upward. Therefore, when a force is applied to the rail 20 from above, the rail 20 is pushed downward and comes into contact with the paper on the base 11. When the force applied to the rail 20 is removed, the rail 20 returns to the initial position by the urging means. Thus, preferably, in the embodiment of the present invention, the rail 20 is supported in a floating state, but the specific means is arbitrary. For example, as shown in FIGS. 4 and 5, a rail 20 is formed from a resin material, and both ends 22 of the rail 20 can be moved up and down with respect to the main body 10. Mount. At this time, for example, as disclosed in the above-mentioned US Pat. No. 5,671,647, the end 22 of the rail 20 is moved up and down by a predetermined interval with respect to the main body 10. In addition to being mounted as much as possible, an elastic body (for example, a spring or the like) is provided between the end 22 and the main body 10 so that the Renole 20 can be supported in a floating state by the elasticity of the spring. Good. In the illustrated embodiment, the rail 20 is provided with a paper pressing portion 21 protruding on the bottom side in a direction perpendicular to the cutting direction. For this reason, the area for pressing the paper placed below at the time of cutting is increased to prevent the paper from shifting. At this time, a scale may be provided on the paper holding portion 21 so that the paper holding portion 21 can be used as a scale. The paper cutting machine 100 is constructed as described above, and the rail 20 is pushed downwards against the elasticity of the spring supporting the rail 20 in a floating state, and the slider 30 is moved to the rail 20. When it is moved upward, the cutter moves while pressing the paper, so that the paper can be cut. At this time, the rail 20 moves up and down with the movement of the slider 30 due to the balance of the force between the elastic force of the spring, the rigidity of the rail 20 and the pressing force of the slider 30. The rail 20 follows the movement of the slider 30 at the time of cutting, and holds the sheet at the cutting progress position between the rail 20 and the base 11 together with the paper presser 21 to prevent the cut sheet from shifting. At this time, preferably, a pressing member (for example, a sponge or the like) for pressing the paper from above is provided on the back surface of the rail 20 over a substantially entire length of the cutting range while slightly protruding from the back surface of the rail 20. Prevent slippage. Also, a pressing member (for example, a sponge) for pressing the paper from below is provided on the upper surface of the base 11 in a similar manner over substantially the entire length of the cutting area to prevent the paper from shifting. These pressing members may be provided on both or one of the base 11 and the rail 20. As described above, the paper cutting machine 100 according to the embodiment of the present invention is particularly configured as disclosed in the above-mentioned U.S. Pat. No. 5,671,647. Provide a cutting function. However, in the embodiment of the present invention, the sheet is aligned from the side by using the guide body 40 at the time of cutting, so that the usability is further improved. At this time, paper In order to enhance the transportability and storage of the cutting machine 100, the guide body 40 is extended vertically to the cutting direction (use position) and stored in the main body 100 (non-use position). It is configured to be able to pivotally move between and. Specifically, as shown in FIG. 7, the guide body 40 is positioned perpendicular to the cutting direction at the time of unfolding so that the paper P indicated by the dashed line can be aligned from the side. Further, as shown in FIG. 2, the guide body 40 is housed in the main body 10 when housed, so that it does not take up space when moving or storing. Hereinafter, the position of the guide body 40 shown in FIG. 7 will be referred to as the deployed position, and the position of the guide body 40 shown in FIG. 2 will be referred to as the accommodation position. At this time, as is apparent from these figures, the length L in the longitudinal direction of the guide body 40 from the pivot center point O to the end 41 in the opposite direction is constant between the deployed position and the accommodated position. This means that the guide body 40 turns in the circumferential direction M shown by the dotted line to switch between the deployed position and the accommodated position, as is clear from FIG. That is, in the embodiment of the present invention, the guide body 40 has one end 44 connected to the main body 10 in a hinge shape, and the other end 41 has a deployed position perpendicular to the cutting direction. The swivel movement between the housing position housed in the main body 10 and the housing position is enabled. Therefore, in the embodiment of the present invention, unlike the prior art, the turning mechanism of the guide body 40 is simply configured, and simply by turning the tip 41 of the guide body 40 about the turning center O. The guide body 40 can be switched between the deployed position and the accommodated position. However, the turning range of the guide body 40 is not limited to 90 degrees. That is, the housing position is preferably located parallel to the cutting direction, but the guide body is turned more than 90 degrees and the housing position is determined so that it is housed deeper in the main body 10. May be. Although not shown in FIG. 7, the guide body 40 is fixed in place to the main body 10 by any engagement means when deployed, as known to those skilled in the art. Is done. However, since the guide body 40 performs only the turning movement, the engaging means switches between the engaged state and the non-engaged state according to the turning movement of the guide body 40. As is apparent from FIG. 7, in order to move the guide body 40 fixed in the deployed position from the engaged state to the disengaged state and to the storage position shown in FIG. The longitudinally extending gas The guide body 40 is operated by applying a force to the end side 41 of the guide body 40 in the circumferential direction M. At this time, the leverage J is applied to the engaging means provided at the end portion 44 on the turning center side of the guide body, so that the engagement state of the engaging means can be easily switched. The engaging portion is provided close to the turning center O of the guide body 40, but the distal end portion 41 is provided further away from the turning center O of the guide body 40. When the hand grips 4 1 and turns it, a moment of force is generated at the engaging part. The moment of this force is the distance L from the center O of rotation to the tip 41 and the tip 41. Therefore, by using the moment of force, the engaging portion can be more efficiently used as compared with the case where the engaging portion on the turning center side is directly operated. By turning, it is possible to release the engagement state of the engagement portion. In the prior art, similar engagement means were provided to fix the guide body at a fixed position, but this configuration was composed of many members, and the processing was troublesome. In order to release the guide from the main body, it was necessary to always pull out the guide body in the vertical direction with respect to the main body, and the above-mentioned moment of force could not be used, and it was difficult to apply the force. In the embodiment, by always moving the guide body 40 only in the circumferential direction M, the usability of the paper cutting machine 100 is improved so that the engagement state can be easily switched when the guide body is deployed. This was not clear in the prior art described above, and the unfolded surface on the base 11 was designed to be able to cooperate with the base 11 to align the sides of the paper during deployment. Guide body 4 0 In addition, the guide body 40 is provided with a step 43. Further, as shown in Fig. 7, when the guide body 40 is unfolded, the guide body 40 cooperates with the scale 13 provided in the main body 10 to form the paper. In order to measure the width of P. Therefore, when unfolding, the scale 13 provided on the main body 10 and the scale 43 provided on the guide body 40 should be used as an integral scale so that the guide body 40 can be used as an integral scale. In this case, since the guide body 40 performs only the turning movement, the accuracy is required when the scales 13 and 43 of the main body 10 and the guide body 40 are used as an integral scale. It is easy to maintain. This becomes clearer than when the guide body 40 is moved vertically with respect to the main body 10 as in the prior art described in the background art. That is, the example For example, if the mechanism for vertically moving the guide body 40 with respect to the main body 10 is broken, it is no longer possible to use the scales 43 of the guide body 40 and the scales 13 of the main body 10 together. Because it becomes. Therefore, in the embodiment of the present invention, the usability of the scales 13 and 43 at the time of deployment is improved by simplifying the turning mechanism of the guide body 40. The hinge-like coupling (turning mechanism) of the guide body 40 can be variously configured, but is preferably composed of only the main body 10 and the guide body 40. In this case, the number of components is minimized, and the cost of the paper cutting machine 100 can be further reduced. Hereinafter, a specific example of the hinge-like coupling structure of the guide body 40 will be described in detail with reference to FIGS. FIG. 8 is a perspective view showing a housing portion 19 provided in the main body 10 so as to house the guide body 40 joined in a hinge shape, and an end portion 44 of the guide body 40 on the turning center side. It is. In the illustrated embodiment, the accommodating portion 19 has a cylindrical portion (shaft portion) 70 projecting vertically downward, and the guide body 40 has the cylindrical portion 70 at the end portion 44 on the turning center side. It has a hole 45 that is fitted so as to be pivotable. However, the cylindrical portion 70 is divided into two or more sections. For example, a slit is inserted into the cylindrical section and the section is divided into four sections. Among these, one section 71 facing the pair is configured to be more flexible than the section 72 facing the other pair. In this section 71, the diameter of the distal end is slightly larger than the inner diameter of the hole 45. For example, as shown in FIG. 9, the section 71 has an inclined surface 73 configured to increase the outer diameter from the end side toward the main body 10. Behind the inclined surface 73, a first cylindrical surface 74 slightly extending in the axial direction is provided. Behind the first cylindrical surface 74, a second cylindrical surface 75 having a smaller outer diameter is provided. The outer diameter of the first cylindrical surface 74 is larger than the inner diameter of the hole 45, and the outer diameter of the second cylindrical surface 75 is substantially equal to the inner diameter of the hole 45. In this configuration, the hinge-like coupling of the guide body 40 to the main body 10 can be performed as follows. That is, when the guide body 40 is strongly pushed into the cylindrical part 70 from the hole part 45, the section 71 is slightly bent inward, and the hole part 45 of the guide body 40 is formed on the inclined surface 73. Proceed along. When the hole 45 advances on the inclined surface 73 and exceeds the first cylindrical surface 74, the hole 45 becomes on the second cylindrical surface 75 and the body 1 0 and the first cylindrical surface 74 side, and are joined in a hinge shape so as to be pivotable. At this time, the section 71 returns to the initial position due to flexibility. When a force in the opposite direction is applied to the guide body 40, the section 71 is similarly bent inward, and the guide body 40 can be separated from the main body 10. Further, in order to determine the deployed position of the guide body 40, a wall portion 76 protruding downward is provided on the rear surface side of the main body 10 to form a stopper. Further, a portion 46 protruding outward in the radial direction is provided at an end portion 44 of the guide body 40 on the turning center side. When the guide body 40 turns by 90 degrees when the guide body 40 turns, the protruding portion 46 comes into contact with the stopper 76 to prevent any further turning movement. Further, an engagement male portion 47 protruding toward the rear surface of the main body 10 is provided at an end portion 44 on the turning center side of the guide body 40 as shown by a broken line. FIG. 10 is a plan view of the rotation-side end portion 44 of the guide body 40 when viewed from above, and shows the vicinity of the engaging male portion 47 in an enlarged manner. In addition, an engaging female portion 77 that can engage with the engaging male portion 47 when deployed is provided on the back side of the main body 10. Then, when the guide body 40 rotates 90 degrees, the engaging male part 47 and the engaging female part 77 are fitted, and the guide body 40 is fixed at the developed position. For example, a convex portion 78 which forms the open end of the engaging female portion 77 shown in FIG. 8 corresponds to a concave portion 48 which forms the projecting portion of the engaging male portion 47 shown in FIG. Engage to fix the guide body 40 in the deployed position. Incidentally, the engaging means composed of the engaging male portion 47 and the engaging female portion 77 is not limited to the illustrated one, but may be variously configured. However, the engaging male portion 47 and the engaging female portion 77 are respectively provided near the turning center O. In addition, the movement of the engagement male portion 47 is performed by the movement of the guide body 40. At this time, the guide body 40 is turned by applying a force to the tip end 41 located away from the turning center O. I do. Therefore, when the guide body 40 is moved from the deployed position to the storage position, the engaged state of the engaging male part 47 and the engaging female part 77 is released by using the moment of the force generated on the turning center side. be able to. Therefore, in the embodiment of the present invention, a large force is not required for operating the engagement means for fixing the guide body 40 at the deployed position, and even a small child can take the action. Further, in the embodiment of the present invention, an engagement portion is provided so as to engage with the end 41 of the guide body 40 and the accommodation part 19 in a pair, and the guide body 40 is fixed at the accommodation position. I do. However, the number and position of the engagement portions for fixing the guide body 40 at the accommodation position are not limited, and, for example, further, the engagement is made at substantially the center of the guide body 40 and the corresponding position of the accommodation part 19. The portions may be provided so as to fit in each pair. This engaging means can be configured in various ways. For example, as shown in FIG. 3, a locking projection 1 for supporting the guide body 40 at the time of storage from below on the back side of the storage portion 19 is provided. 8 is provided. Then, when the guide body 40 is moved to the storage position, the end 41 of the guide body 40 and the locking projection 18 are engaged in a pair. For example, a concave portion is provided on the surface of the locking projection 18 facing the guide member 40, and a convex portion is provided at a position corresponding to the guide member 40, and the guide member is moved in the circumferential direction from the deployed position. Then, when the guide body is moved to the accommodation position, the projection and the recess are engaged with each other to fix the accommodation position of the guide body. At this time, when the projections and the recesses are engaged with each other, for example, a clicking sound may be generated so that the user can clearly recognize that the guide body has been fixed at the accommodation position by hearing. ,. With the above-described configuration, in the embodiment of the present invention, the guide body 40 is hingedly connected so that only the swiveling movement with respect to the main body 10 is possible, and the guide body 40 is connected to the cutting direction. The vertical deployment position and the accommodation position accommodated in the main body 10 are easily switched by a single operation. In addition, as described above, the guide body 40 is hingedly connected so that only the swivel movement is possible, so that the switching of the engagement state of the guide body 40 particularly at the deployed position occurs on the swivel end side. Make it easy to use the force of the moment. Furthermore, it is possible to easily use the scales 13 and 43 provided on the main body 10 and the guide body 40 simply by turning the guide body 40. Industrial applicability

 INDUSTRIAL APPLICABILITY The present invention has a simplified structure and enhanced usability, so that it can be used from a wide range of ages. However, the object to be cut by the paper cutting machine is not limited to paper, and various objects such as cardboard and photographs may be cut.
