FIG. 1 is a perspective view showing a cutting machine according to an embodiment of the present invention.
The cutting machine 10 is composed of a base 1, a fixing plate 2, a slider 30, a rail 4, and a support 5, and is mounted on the base 1 by moving the slider 30 along the rail 4. The placed sheet is cut by a disc-shaped cutting blade attached to the slider 30.

The base 1 is a table on which a sheet material such as paper is placed, and both ends are provided with steps 11 and 12 for contacting the edge of the sheet. The placement surface 7 is appropriately provided with a grid-like scale, a mark according to the standard paper size, and the like.
A rubber cutter mat 13 is embedded in one side of the base 1 where the rail 4 is provided.

A rail 4 is attached to one side of the base 1. As shown in FIG. 2, the rail 4 is configured by attaching a rail member 40 having a smooth sliding surface to a rail support body 41.
The rail support body 41 is a rectangular flat plate that is long in the direction along the rail member 40, has two rail mounting portions 42 on the upper surface, and a fixing plate 2 for fixing the seat on the base at the lower surface. Is forming.

The rail 4 is constructed on support bodies 5 provided at both ends of the base 1. A spring 51 is provided between the support 5 and the base 1. The rail 4 is biased upward by the spring 51 so that a gap for inserting a sheet is formed between the spring 51 and the mounting surface 7.
A slider 30 for a cutting machine according to the present invention is slidably attached to the upper surface of the rail 4. Hereinafter, the configuration of the slider 30 will be described.

The slider 30 includes a base portion 31 engaged with the rail 4, a main body portion 32 for performing a sliding operation, and a holder portion 34 that rotatably holds the cutting blade 33 in a housing portion provided on the side wall surface. And a lid portion 35 that covers the cutting portion 33 and covers the accommodating portion.
A spring 36 is interposed between the main body portion 32 and the base portion 31, and when the cutting edge of the cutting blade 33 positioned above the fixing plate 2 in the initial state pushes down the main body portion 32. Are pushed down to a position below the fixed plate 2 (see FIG. 3).

A holder portion 34 for holding the cutting blade 33 is attached to the side wall surface of the main body portion 32.
A concave accommodating portion for accommodating the disc-shaped cutting blade 33 is formed on the side wall portion of the holder portion 34, and the shaft blade provided in the main body portion 32 and the holder portion 34 has the cutting blade 33. The cutting blade 33 is rotatably supported by inserting the rotating shaft 37.
The holder portion 34 is provided with an engaging portion with the lid portion 35, and is attached to the main body portion 32 via the holder portion 34 by turning the handle to engage with the engaged portion of the lid portion 35. Thus, an integrated outer shape as the slider 30 is formed (see FIG. 4).

By attaching the slider 30 to the rail 4 and pressing down the slider 30 strongly, the rail support 41 is pressed on the bottom surface of the base portion 31, and the fixing plate 2 formed on the lower surface is brought into close contact with the mounting table 7. Thereby, the sheet | seat on the mounting base 7 can be fixed.
The slider 30 has a shape protruding at the front position. In other words, the upper protrusion of the slider 30 is formed at the front portion in the cutting direction so that the upward protruding portion 38 is formed. The protrusion 38 is formed by inclining the rear wall 39 on the slider upper surface on the rear side in the cutting direction. In this case, the inclination angle θ of the rear wall 39 is designed to make an angle of 20 ° to 40 ° (preferably 30 °) with respect to the rail 4 (see FIG. 5).

Thus, in the cutting machine 10 that includes the base 1, the fixed plate 2, the slider 30, and the rail 4, and the rail 4 is biased upward, the cutting direction of the slider 30 is laid on the support 5. By projecting the front position, the cutting machine 10 is placed on the table with the rear in the cutting direction facing forward, and the slider 30 is moved to operate the protruding portion 38 when the sheet to be cut is moved. A pressing force can be exerted in the direction B in which the is tilted forward (see FIG. 6).
That is, by performing an operation for moving the slider 30 at the same time as pushing down the protrusion 38, a pressing force in the moving direction (that is, the horizontal direction) acts on the slider 30, and the slider 30 is caused by the moment. The front position of is pushed down strongly. As a result, the fixing plate 2 in front of the cutting direction A is pressed through the rail 4.

As a result, it is possible to prevent the fixed plate 2 from being lifted from the cutting point to the front, and to prevent displacement of the sheet.
Further, since the rear wall surface 39 on the rear side in the cutting direction of the protruding portion 38 is inclined, pressing the inclined rear wall surface 39 causes the slider 30 to press the slider 30 forward in the cutting direction. It can be distributed to a downward force for pushing down and a horizontal force to move.
This eliminates the need to adjust the force when moving the slider 30 while pressing it down (ie, fine adjustment of the downward pressing force and the horizontal pressing force). Obtainable.

In particular, since the inclination angle θ of the wall surface 39 on the rear side in the cutting direction of the slider 30 is set to 20 ° to 40 ° (preferably 30 °) with respect to the rail 4, the pressing force against the slider 30 is pushed down. It is possible to disperse in a moderate amount and a force for moving.
Further, when the inclined rear wall surface of the slider 30 is moved while being pushed by the palm, the work can be performed in a natural posture.

In the slider 30 of the present invention, the protruding portion 38 is not necessarily formed by making the upper surface of the slider 30 inclined, and a linear wall surface 39 like the protruding portion 38 'shown in FIG. It's okay.
Further, the cutting machine 10 of the present invention includes a base on which a sheet is placed, a fixing plate that presses the sheet onto the base, a slider with a cutting blade, a rail on which the slider is slidably mounted, and a rail upward. Any structure may be used as long as it includes a support body that is erected in a state of being urged toward the rear side, for example, on the back side of the rail member 40 ′ as in the cutting machine 10 ′ illustrated in FIG. The rail 4 ′ may be configured by a horizontal member 44 disposed along the pair and a pair of link bars 43 and 43 rotatably attached to both end portions 44 a of the horizontal member 44.

The rail 4 'is supported in a state of being biased upward by support bodies 5' provided at both ends of the base 1 ', and the lower end portion 43a of each link bar 43 can be rotated to the base 1'. When the rail 4 'moves up and down, the horizontal state can be maintained.
The fixing plate which consists of another member is attached to rail 4 ', and the slider for cutting machines of this invention is attached so that rail 4' may be straddled. By pushing down the slider, the rail 4 'is also pushed down, and the horizontal member 44 moves in the cutting direction while being guided by the guide portion 45 provided on the back side of the rail member 40'. Accordingly, the link bar 43 is inclined toward the cutting direction A. At this time, the position of the link bar 43 is restricted by the guide portion 51 provided on the support 5 ′, and the link bar 43 is inclined only in the cutting direction A.

In the cutting machine 10 ′ having such a parallel link mechanism, the cutting direction is often specified, and it is necessary to display the cutting direction. However, in the present invention, the front portion in the cutting direction is protruded on the upper surface. Since the slider having the shape is attached to the rail 4 ′, the protruding portion serves as a mark, and the cutting direction (that is, the direction in which the link bar 43 is inclined) is easily recognized.
As a result, it is possible to prevent the wrong direction for moving the slider.

  Further, in such a link type cutting machine 10 ′, the rail 4 ′ moves up and down while maintaining a horizontal state. Therefore, when the slider is moved, the protrusion provided at the front portion in the cutting direction on the upper surface thereof. When is pushed down, it is possible to prevent the front position of the slider from being pushed down excessively. Accordingly, it is possible to press the sheet uniformly while preventing the fixing plate from floating in front of the cutting direction, and it is possible to more effectively prevent misalignment.

  The present invention can be applied in all industrial fields as a cutting machine for cutting all sheet-like materials such as paper, vinyl, and leather.
