Patent number: 10808833Abstract: In a shift device, when a switch is operated, a moving portion, a first lock plate, a second lock plate and a third lock plate are moved toward a vehicle front side, and placement of the first lock plate, the second lock plate and the third lock plate at a return path is cancelled. Therefore, if the switch is operated when a lever is placed at other than a “P” position, due to a guide pin being moved along the return path toward an upper side by urging force of a return spring, the guide pin is returned to a vehicle front side end of a first lateral path, and the lever is returned to the “P” position. Due thereto, the lever can easily return to the “P” position from other than the “P” position.Type: GrantFiled: August 7, 2015Date of Patent: October 20, 2020Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Susumu Mega, Yoshihisa Hirano

Patent number: 9730658Abstract: In a radiographic imaging apparatus, a radiation image of an object is detected by use of one of first and second electronic cassettes, to input the radiation image to the console device. The first electronic cassette is changed over between a normal transmission mode and a relay transmission mode. In the normal transmission mode, the radiation image is transmitted through a path from the first electronic cassette to the console device, and in the relay transmission mode, the radiation image is transmitted from the first electronic cassette to the second electronic cassette wirelessly and then from the second electronic cassette to the console device. Transmission of a radiation image can be performed reliably without unwanted interruption, because an indirect path of the relay transmission mode can be used even upon occurrence of a technical problem of inefficiency in the normal transmission mode.Type: GrantFiled: May 4, 2016Date of Patent: August 15, 2017Assignee: FUJIFILM CorporationInventors: Takashi Tajima, Tetsuya Tsuji, Haruyasu Nakatsugawa, Yoshihisa Hirano
