Abstract

(57)【要約】 【課題】 給紙カセット等の給紙部材に設けるサイドガ イドの連動機構を構成するラック・ピニオンに対して、 前記ピニオンと同軸に細かいギヤを設けたストッパギヤ を一体に設け、ストッパ部材による係止手段により固定 可能にする。 【解決手段】 用紙の両側部を規制するサイドガイド1 0は、スライド部材12、12aのラック13、13a をピニオン20に噛合わせて互いに離接する方向に連動 移動させる。前記ピニオン20と一体にストッパギヤ2 1を設け、ストッパ部材25の係止爪部材26を噛合わ せて、ピニオン20を弱い力では回転しないように保持 する。前記ストッパギヤ21に細かいピッチの歯を設 け、係止爪部材26に複数設けた突起の1つが噛合うよ うにして固定保持し、ピニオンがラックの移動により回 転する時には、ストッパ部材が弾性により外れるように する。
PROBLEM TO BE SOLVED: To integrally mount a stopper gear having a fine gear coaxial with a pinion, to the rack pinion forming an interlocking mechanism of a side guide mounted on a paper feeding member such as a paper feeding cassette or the like, and to fix it by a locking means formed by a stopper member. SOLUTION: In the side guide 10 for controlling both sides of the paper, racks 13, 13a of sliding members 12, 12a are engaged with the pinion 20 to be interlocked and moved in the directions to be separated from or brought into contact with each other. The stopper gear 21 is integrated with the pinion 20, and a locking claw member 26 of the stopper member 25 is engaged with the stopper gear to hold the pinion 20, whereby the pinion can not be rotated by weak force. The stopper gear 21 has teeth at fine pitches, and is engaged with one of plural projections formed on the locking claw member 26 to be fixed and held, whereby the stopper member is elastically disengaged in rotating the pinion by the movement of the racks.
