Patent number: 10959691Abstract: A housing of an electronic cassette has an inclined surface which is formed between a side surface and a rear surface thereof and inclined relative to the side surface and the rear surface. An antenna opening through which a radio wave is transmitted is formed on the inclined surface. Since the antenna opening is formed on the inclined surface, the antenna opening is not blocked by a rear plate of a holder of an upright radiographic stand or a supine radiographic stand, and the antenna opening is not blocked by a side panel of an outer grid. Both in the case where the electronic cassette is set to the holder and in the case where the outer grid is attached to the electronic cassette, it is possible to perform stable wireless communication.Type: GrantFiled: June 2, 2020Date of Patent: March 30, 2021Assignee: FUJIFILM CorporationInventors: Akihito Bettouyashiki, Makoto Kitada, Jun Enomoto

Patent number: 10682105Abstract: An electronic cassette comprises a main battery which is detachably attached to a battery loading unit, and a sub-battery which supplies electricity to a bias power circuit and so on in substitution for the main battery. A power source selector changes the power source to the sub-battery from the main battery when it is judged that a replacement operation of the main battery is started. Since supply of the electricity to the bias power circuit is continued, and the bias voltage continues being applied to a photoelectric converter without a break, there is no need to perform a photoelectric conversion stabilizing process and an offset correction image detecting process after turning on of the main power. Therefore, a start-up time TR2 is largely shortened from a start-up time TR1.Type: GrantFiled: August 8, 2018Date of Patent: June 16, 2020Assignee: FUJIFILM CorporationInventors: Sho Shimizukawa, Makoto Kitada, Jun Enomoto

Patent number: 10335111Abstract: A center position of a female connector is located near to a rear surface of a housing compared with a center position of the housing in a thickness direction of the housing of an electronic cassette. An inclined surface, which is inclined relative to a side surface and the rear surface of the housing, is formed between the side surface and the rear surface. The female connector is formed on the inclined surface. Therefore, it is possible to attach an outer grid provided with a longer side panel to the housing, in comparison with the case where the center position of the female connector is made coincident with the center position of the housing in the thickness direction of the housing, without requiring any processing.Type: GrantFiled: August 28, 2015Date of Patent: July 2, 2019Assignee: FUJIFILM CorporationInventors: Jun Enomoto, Makoto Kitada
