COVER OPENING/CLOSING STOPPER AND IMAGE FORMATION DEVICE

PROBLEM TO BE SOLVED: To provide a cover opening/closing stopper that can contribute to miniaturization of an image formation device.SOLUTION: A cover opening/closing stopper includes a housing 2, a rear cover 21, a first arm 80, a second arm 90 and an abutment part 83 disposed in the first arm 80 and capable of abutting on a cam part 23. In a process that the rear cover 21 displaces from an opened position to a closed position, the abutment part 83 abutting on the cam part 23 makes a slide pin 92a in a fourth end part 92 of the second arm 90 slide toward a distant side from a near side to a rear cover rotating shaft part 21a in a long hole part 221.SELECTED DRAWING: Figure 9 【課題】画像形成装置の小型化に貢献できるカバー開閉ストッパが望まれている。【解決手段】カバー開閉ストッパは、筐体２と、リアカバー２１と、第１アーム８０と、第２アーム９０と、第１アーム８０に配されカム部２３に当接可能な当接部８３と、を備え、リアカバー２１が開放位置から閉塞位置に変位する過程で、当接部８３がカム部２３に当接することにより、第２アーム９０の第４端部９２における摺動ピン９２ａが長孔部２２１内をリアカバー回動軸部２１ａに近い側から遠い側へ向けて摺動する。【選択図】図９
