【考案の詳細な説明】
この考案は、シート状の被搬送物例えはプリンタ等にお
けるプリント紙の給紙あるいは排紙を行なうローラに関
するものである。[Detailed Description of the Invention] This invention relates to a roller that feeds or discharges printed paper in a printer or the like, for example, a sheet-like conveyed object.
従来この種のローラとして、第1図に示すものがあった
。As a conventional roller of this type, there is one shown in FIG.
図において、1は紙搬送路面の上側に設けられた上側ロ
ーラ軸、2は上側ローラ軸1と平行かつ紙搬送路面の下
側に設けられた下側ローラ軸、3および4は上側、下側
ローラ軸1,2上の所定位置に互いに対向して設けられ
た同径の上側および下側ローラである。In the figure, 1 is an upper roller shaft provided above the paper transport path, 2 is a lower roller shaft parallel to the upper roller shaft 1 and provided below the paper transport path, 3 and 4 are upper and lower roller shafts. Upper and lower rollers having the same diameter are provided at predetermined positions on roller shafts 1 and 2 to face each other.
ここで、上側および下側ローラ3,4間に適度の接圧力
が加わるように上側ローラ軸1の両端(軸受)にはばね
等により力Fが加えられており、上側および下側ローラ
1,2を同じ速さで、それぞれ矢印の方向へ回転させる
ことにより、上側、下側ローラ3,4間に介挿される紙
(図示せず)を搬送する。Here, a force F is applied by a spring or the like to both ends (bearings) of the upper roller shaft 1 so that an appropriate contact force is applied between the upper and lower rollers 1 and 4. By rotating the rollers 2 at the same speed in the directions of the arrows, paper (not shown) inserted between the upper and lower rollers 3 and 4 is conveyed.
しかし、従来の搬送ローラは上側ローラ軸1の両端のみ
に力Fを加えているので、第2図の破線のごとく上側ロ
ーラ軸1がたわみ、上側ローラ3を介して紙の中央部へ
加わる接圧力がその両端部に比べて小さくなる。However, since the conventional conveyance roller applies force F only to both ends of the upper roller shaft 1, the upper roller shaft 1 is deflected as shown by the broken line in FIG. The pressure is lower than at both ends.
この接圧力の不均等により紙が蛇行するなどの欠点があ
った。This uneven contact pressure caused the paper to meander.
この考案は上記のような従来のものの欠点を除去するた
めにさなれたもので、被搬送物に加わる接圧力を均等に
し、被搬送物の蛇行を防ぐことを目的としている。This invention was developed in order to eliminate the above-mentioned drawbacks of the conventional ones, and its purpose is to equalize the contact pressure applied to the object to be transported and to prevent the object from meandering.
この考案の一実施例を図について説明する。An embodiment of this invention will be explained with reference to the drawings.
第3図において、従来の第1図と異なる点は5の加圧部
材を上側ローラ軸1の上側ローラ3.3間に設けた点で
、この加圧部材5は適度な重量を有し、重力方向すなわ
ち下方に力が加わるよう構成されている。In FIG. 3, the difference from the conventional FIG. 1 is that a pressure member 5 is provided between the upper rollers 3 and 3 of the upper roller shaft 1, and this pressure member 5 has an appropriate weight. It is configured so that force is applied in the direction of gravity, that is, downward.
第3図において、加圧部材5を設けることにより、上側
ローラ軸1の中央部においても下方に力が加えられ、従
来の欠点であった上側ローラ軸1のたわみがなくなるの
で、均等な接圧力が紙の各部に加わり、紙は蛇行するこ
となく搬送される。In FIG. 3, by providing the pressure member 5, a downward force is also applied to the center of the upper roller shaft 1, and the deflection of the upper roller shaft 1, which was a drawback of the conventional method, is eliminated, so the contact force is uniform. is applied to each part of the paper, and the paper is conveyed without meandering.
なお上記実施例では、加圧部材5の重量により上側ロー
ラ軸1のたわみを防止するようにしたが、これを弾性部
材で構成するようにしてもよく、またこれらを併用する
ようにしてもよい。In the above embodiment, the weight of the pressure member 5 prevents the upper roller shaft 1 from bending, but this may be made of an elastic member, or these may be used in combination. .
またこの加圧部材5を着脱可能に構成して、紙の厚さ等
に応じてその重量を調整するようにしてもよい。Further, the pressure member 5 may be configured to be detachable so that its weight can be adjusted depending on the thickness of the paper and the like.
また、上記実施例では紙を搬送する場合について述べた
が、その化シート状の被搬送物例えばフィルム、布等を
搬送する場合にも同様の効果を奏する。Further, although the above embodiment describes the case of conveying paper, the same effect can be achieved when conveying a sheet-like object such as a film or cloth.
以上のようにこの考案によれば、回転ローラの軸方向中
心部を回転ローラが対向する方向に加圧する加圧部材を
設けたので、シート状被搬送物に加わるローラ接圧力を
ほぼ均等にすることができ、シート状被搬送物の蛇行を
防止することができる。As described above, according to this invention, a pressure member is provided that presses the axial center of the rotating roller in the direction in which the rotating roller faces, so that the roller contact pressure applied to the sheet-like conveyed object is approximately equalized. This makes it possible to prevent the sheet-like object from meandering.
第1図は従来の搬送ローラを示す斜視図、第2図は第1
図の要部を示す斜視図、第3図はこの考案の一実施例を
示す斜視図である。
図中、1は上側ローラ軸、2は下側送ローラ軸、3は上
側ローラ、4は下側ローラ、5は加圧部材である。
なお、図中、同一符号は同−又は相当部分を示す。Figure 1 is a perspective view of a conventional conveyance roller, and Figure 2 is a perspective view of a conventional conveyance roller.
FIG. 3 is a perspective view showing an embodiment of this invention. In the figure, 1 is an upper roller shaft, 2 is a lower feed roller shaft, 3 is an upper roller, 4 is a lower roller, and 5 is a pressure member. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.
