To smoothly deliver a medium with a simple configuration.SOLUTION: In an additional paper feeding device 3 of an image formation device 1, a positioning part 80 provided at a left base part 61L of an additional main body part 51 causes a central axis C81 and a central axis C82 to substantially match by inserting a part of a shaft 82 to an upper portion of a cylindrical part 81, and the vicinity of the upper end thereof is defined as a first projection 71 as well as the vicinity of the lower end there of is defined as a first hole part 75. In the image formation device 1, when an additional paper feeding device 3A is connected to the upper side of an additional paper feeding device 3B, the first projection 71 of the additional paper feeding device 3B is inserted to the first hole part 75 of the additional paper feeding device 3A. Thus, in the image formation device 1, the central axes C82 of the shafts 82 are made to substantially match between the additional paper feeding devices 3A and 3B, so as to position both of them in a front/back direction and a right/left direction with extremely high precision.SELECTED DRAWING: Figure 7 【課題】簡易な構成により媒体を円滑に受け渡し得るようにする。【解決手段】画像形成装置１の増設給紙装置３は、増設本体部５１の左基体部６１Ｌ設けた位置決め部８０において、筒状部８１の上側部分にシャフト８２の一部を挿入して中心軸Ｃ８１に対し中心軸Ｃ８２をほぼ一致させ、その上端近傍を第１突起７１とし、その下端近傍を第１孔部７５とした。画像形成装置１では、増設給紙装置３Ｂの上側に増設給紙装置３Ａを重ねる場合に、増設給紙装置３Ａの第１孔部７５に、増設給紙装置３Ｂの第１突起７１を挿入させる。これにより画像形成装置１では、増設給紙装置３Ａ及び３Ｂの間で、互いのシャフト８２の中心軸Ｃ８２をほぼ一致させることができ、前後方向及び左右方向に関して極めて高い精度で互いを位置決めすることができる。【選択図】図７
