Abstract

The invention discloses a power supply unit and a radiation imaging apparatus including the same. The radiation imaging apparatus includes: a support base arranged to support a radiation detection panel arranged to detect incident radiation; a power source including a positive terminal portion and a negative terminal portion; a substrate electrically connected to the positive terminal portion and the negative terminal portion; an insulating sheet disposed between the support base and the power source and substrate, wherein the power source and substrate are fixed to the insulating sheet; and a sheet fixing member arranged to fix at least one of the plurality of sheet ends of the insulating sheet to the support base.

Description

technical field [0001] The present invention relates to a power supply unit including a secondary battery and a radiation imaging apparatus including the power supply unit. Background technique [0002] A radiographic apparatus that detects the intensity distribution of radiation passing through an object to obtain radiographic images is widely used in industrial nondestructive testing and medical diagnosis. In order to be able to quickly image most parts of a subject, a radiation imaging apparatus with improved portability and operability is being developed. For example, there is known a radiographic apparatus having improved portability by having a built-in or detachable power supply for power supply. [0003] Rechargeable secondary batteries are generally used for power sources, and capacitors in particular are advantageous in that they allow faster charging and longer charge / discharge cycle life than lithium-ion secondary batteries and lead-acid batteries. In Japanese ...
