PROBLEM TO BE SOLVED: To provide a connecting/disconnecting mechanism for easily connecting/disconnecting two units to/from each other, and to provide a combined device equipped therewith.SOLUTION: A hook portion has a branch 332 formed at the longitudinal front end in such inclination that its front-end side face goes down to the front end, where spring force is imparted toward the branch. It has a hook 302 to be moved toward the front end with the application of external force, restored to the original position concurrently with the decay of the external force, and reciprocatingly moved toward the front with the front end being displaced its length or greater to the opposite direction to the branch. A hook supporting portion has an abutting body 112 which is pushed by the front end and moved when the hook is moved toward the front end, and a hook support 102 which engages with the branch 332 before the hook is moved toward the front end and which is moved together with the abutting body in the state of disengaging from the branch 332 when the hook is moved toward the front end.COPYRIGHT: (C)2008,JPO&INPIT【課題】2つのユニットの連結および解除が容易な連結・解除機構、および、そのような連結・解除機構を備えた複合装置を実現することができる。【解決手段】フック部は、長手方向の先端部分に、先端側の側面が先端に向かって下るように傾斜を持つ枝(332)が形成され、この枝の方向にばね力が付与され、外力の印加によって先端方向に移動し、外力の消滅とともに元の位置に復帰し、先端方向への往復移動時には先端部分が前記枝とは反対方向にその長さ以上に変位した状態で移動するフック(302)を有し、フック受け部は、前記フックの先端方向への移動時にその先端で押されて移動する当接体(112)と、前記フックの先端方向への移動前の状態において前記枝と係合し、前記フックの先端方向への移動時に前記枝との係合が外れた状態で前記当接体と一緒に移動するフック受け(102)を有する。【選択図】図7
