Abstract
Description
図1は、本発明の実施の形態にかかるカードリーダ1の概略構成を説明するための側面図である。図2は、図1に示すカード2の平面図である。図3は、図1に示すカードリーダ1の平面図である。
図4は、図1に示すカードリーダ1の斜視図である。図5は、図3に示す歯車32~35、43~46を支持軸38、39、52、53から取り外した状態の平面図である。図6は、図1に示すカードリーダ1の一部分の斜視図である。図7は、図1に示すカードリーダ1の一部分の分解斜視図である。
以上説明したように、本形態では、支持軸38、39は、支持軸38、39の軸方向と左右方向とが一致するように配置されている。また、歯車32、34は、支持軸38の軸方向で重なるように支持軸38に回転可能に支持され、歯車33、35は、支持軸39の軸方向で重なるように支持軸39に回転可能に支持されている。そのため、本形態では、前後方向に所定の間隔で配置される2本の支持軸38、39を用いて、4個の減速用の歯車32~35を配置することができる。すなわち、本形態では、減速用の歯車32~35を支持する支持軸38、39の数が2本であっても、減速用の歯車32~35の数を増やすことができる。また、本形態では、減速用の歯車32~35の数を増やすことができるため、大歯車部32a~35aのピッチ円径を小さくしても、モータ18と搬送ローラ20との間の減速比を大きくすることが可能になる。
上述した形態は、本発明の好適な形態の一例ではあるが、これに限定されるものではなく本発明の要旨を変更しない範囲において種々変形実施が可能である。
