Publication number: 20150150509Abstract: There is used a medical diagnostic apparatus having a bed that supports an examinee in a prone position, and has a first opening in which an object being a part of the examinee is inserted, a measurement unit that has a second opening which is smaller than the first opening and in which the object is inserted through the first opening, a moving mechanism that moves the bed and the measurement unit relative to each other, and a shock absorbing member that is disposed between the bed and the examinee. The shock absorbing member has a portion covering a part of the first opening at least in a direction where the bed and the measurement unit move relative to each other, and is arranged such that the covering portion does not cover the second opening.Type: ApplicationFiled: June 25, 2013Publication date: June 4, 2015Inventor: Yohei Motoki

Patent number: 8070547Abstract: A spacer having bending portions in the vicinity of end portions is used, and grip portions provided between the end portions and the bending portions are held by holding units. Tension is applied to the spacer in a longitudinal direction, and the grip portions are rotated to release a rotational moment applied to a longitudinal portion of the spacer. In this state, the spacer is attached to a rear plate.Type: GrantFiled: June 25, 2010Date of Patent: December 6, 2011Assignee: Canon Kabushiki KaishaInventors: Yohei Motoki, Akihiro Kimura
