DRAWER MECHANISM, IMAGE FORMATION APPARATUS AND ELECTRONIC EQUIPMENT

PROBLEM TO BE SOLVED: To provide a drawer mechanism which can be easily attached/detached, and also easily operated.SOLUTION: A drawer mechanism includes: a drawer part which is provided in a freely-drawable manner in the drawing direction in a housing; a support shaft 142 to which the drawer part is inserted and which extends in the drawing direction; a gripping part 141 which is formed on a front side end portion in the drawing direction of the support shaft; and a lock part 143 which is formed on a depth side end portion in the drawing direction of the support shaft, and switches between the normal state where the drawer part is freely drawable and the lock state where the drawer part is fixed in a non-drawable manner by integrally rotating the support shaft and the lock part with rotation of the gripping part. The lock part includes a fitting section 15 which is fit into a fixation member 102 provided in the drawer part in the lock state. The fitting section includes: a first wall portion which extends in the drawing direction from the root; a second wall portion which is brought into contact with the fixation member in the lock state; and an inclined portion which is formed in an inclined manner with respect to the drawing direction between the first wall portion and the second wall portion.SELECTED DRAWING: Figure 4 【課題】着脱が容易でかつ操作しやすい引き出し機構の提供。【解決手段】筐体内において引き出し方向に引き出し自在に設けられた引き出し部と引き出し部を挿通して引き出し方向に伸びた支持軸１４２と、支持軸の引き出し方向の手前側端部に形成された把持部１４１と、支持軸の引き出し方向の奥側端部に形成されたロック部１４３とを有し、把持部の回動によって支持軸とロック部とを一体に回動させることで引き出し部を引き出し自在な通常状態と、引き出し部が引き出し不能に固定されたロック状態とを切り替える引き出し機構であって、ロック部は引き出し部に設けられた固定部材１０２とロック状態において嵌め合う嵌合部１５を有し、嵌合部は付根から引き出し方向に伸びた第１の壁部と、ロック状態において固定部材と当接する第２の壁部と、第１の壁部と第２の壁部との間に引き出し方向に対して傾斜して形成された傾斜部とを有する。【選択図】図４
