Patent number: 11397403Abstract: An image formation apparatus according to an embodiment may include: an apparatus housing including a stacker and an opening provided at the stacker; a fixation device removably attached to the apparatus housing through the opening and including a handle rotatable between an upright position and a laid-flat position; and a laid-flat position-keeping detent mechanism. In a state where the fixation device is attached to the apparatus housing, a portion of the fixation device that is exposed from the opening provided at the stacker forms a portion of the stacker and a connector of the fixation device is mated to a connector of the apparatus housing. By at least a predetermined force being applied to the handle to transition the handle from the upright position to the laid-flat position, the laid-flat position-keeping detent mechanism allows the handle to transition to the laid-flat position and keeps the handle in the laid-flat position.Type: GrantFiled: August 16, 2021Date of Patent: July 26, 2022Assignee: Oki Electric Industry Co., Ltd.Inventors: Tetsuya Uehashi, Teruo Soeda
