Description

本発明は、紙などのシート材を裁断する裁断機に関し、特に、裁断する際のシートのズレを防止できる裁断機に関する。 The present invention relates to a cutting machine for cutting a sheet material such as paper, in particular, it relates to a cutting machine capable of preventing deviation of a sheet at the time of cutting.

しかしながら、上記の裁断機において、スライダ４を押し下げながら手前から前方に向けて裁断方向Ａに移動させる際、手圧による押し下げ力がスライダ３の手前側の部位３ａ（即ち、裁断方向Ａの後方）に作用されがちなので、固定板２の前方部位２ｂに浮きが生じ易い。
このため、裁断途中でシートが動き、裁断ラインにズレが生ずる場合があった。
そこで、本発明は裁断方向の前方において固定板に浮きが生ずるのを防止し、裁断途中でシートの位置がずれてしまうことを防止できる裁断機の提供を目的とする。 However, in the above cutting machine, when the slider 4 is pushed down and moved in the cutting direction A from the front side toward the front side, the pressing force due to the manual pressure is applied to the portion 3a on the near side of the slider 3 (that is, the rear side in the cutting direction A). Therefore, the front portion 2b of the fixing plate 2 tends to float.
For this reason, the sheet may move in the middle of cutting, and the cutting line may be displaced.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cutting machine that can prevent a fixed plate from being lifted in front of the cutting direction and prevent the sheet from being displaced during cutting.

上記課題を解決するために、本発明に係る裁断機は、シートが載置される基盤と、シートを基盤上に押し付ける固定板と、裁断刃を装着したスライダと、該スライダがスライド可能に取り付けられるレールと、該レールを上方に向けて付勢させた状態で架設する支持体とを含んで構成され、前記レールに沿って前記固定板を設け、前記スライダを押し下げながら裁断方向に移動させることで、前記固定板でシートを固定しながら裁断する裁断機であって、前記スライダの上面の裁断方向前方の部位に、該スライダを移動させる際に操作するための操作部を、上方に向けた突出部として構成したことを特徴とするものである。 In order to solve the above-described problems, a cutting machine according to the present invention includes a base on which a sheet is placed, a fixing plate that presses the sheet onto the base, a slider having a cutting blade, and the slider slidably attached. And a support that is installed in a state where the rail is urged upward, the fixing plate is provided along the rail, and the slider is moved in the cutting direction while pushing down the slider. A cutting machine that cuts while fixing the sheet with the fixing plate, and an operation portion for operating the slider is moved upward to a portion of the upper surface of the slider in front of the cutting direction. It is characterized by comprising as a protruding part.

この場合、上記突出部の裁断方向後方側の後壁面を、前記レールに対して２０°〜４０°の角度をなすように傾斜状に構成してもよい。 In this case, the rear wall surface on the rear side in the cutting direction of the protrusion may be configured to be inclined so as to form an angle of 20 ° to 40 ° with respect to the rail .

請求項２に係る裁断機は、突出部の裁断方向後方側の壁面を傾斜状にしたので、その傾斜状の後壁面を押すことで、スライダに対する裁断方向前方に向けての押圧力を、スライダを押し下げるための下方向の力と、移動させるための水平方向の力とに分散させることができる。これによって、スライダを押し下げながら移動させる際の力加減の調節が不要となるので、熟練者でなくとも美しい裁断ラインを得ることができる。
また、スライダの後壁面の傾斜角を、レールに対して２０°〜４０°の角度としたので、スライダに対する押圧力を、スライダを押し下げるための力と、移動させるための力に、程良く分散させることができる。また、スライダの傾斜状の後壁面を掌で押しながら移動させる際に、自然な姿勢で作業を行なうことができる。 In the cutting machine according to claim 2, since the wall surface on the rear side in the cutting direction of the protruding portion is inclined, pressing the inclined rear wall surface causes the slider to apply a pressing force toward the front in the cutting direction with respect to the slider. Can be distributed to a downward force for pushing down and a horizontal force for movement. As a result, it is not necessary to adjust the force when the slider is moved while being pushed down, so that a beautiful cutting line can be obtained even if it is not an expert.
In addition , since the inclination angle of the rear wall of the slider is 20 ° to 40 ° with respect to the rail, the pressing force on the slider is moderately distributed between the force for pushing down the slider and the force for moving the slider. Can be made. Further, when the slider is moved while pushing the inclined rear wall surface of the slider with a palm, the work can be performed in a natural posture.
