  • Patent number: 9535176
    Abstract: Disclosed is a radiation image capturing apparatus including the following. A sensor panel includes a plurality of radiation detecting elements aligned two-dimensionally. A case stores the sensor panel. A ventilation hole is provided in the case. A ventilation filter is provided in the ventilation hole and prevents infiltration of liquid into the case. Air flows in and out of the case through the ventilation hole and a thickness of the case is maintained at a predetermined thickness when outside pressure changes.
    Type: Grant
    Filed: April 8, 2015
    Date of Patent: January 3, 2017
    Assignee: KONICA MINOLTA, INC

  • Patent number: 8637822
    Abstract: A case constituting a cassette-type detector has a first lid member which closes an opening of the case arranged therein. An exterior wall hole is provided to a corner section of the first lid member. This makes it possible to detect appropriate radiological images all the time since even if an unexpected shock is applied to the corner section, the shock is absorbed by the deformation of the corner section to prevent the damage of the built-in detection unit of the cassette-type detector.

  • Patent number: 6778262
    Abstract: There is described a film conveying apparatus drawably mounted onto an image-forming apparatus. The apparatus includes a film stacking section to stack photosensitive films on it, a conveying device being movable between a film conveying position and a film supplying position to convey the photosensitive films one by one from uppermost one, a first shading member that encloses both the film stacking section and the conveying device and has a conveyance opening from which the photosensitive film is conveyed out by the conveying device so as to maintain a light-shading state for both the film stacking section and the conveying device when the conveying device parks at the film conveying position; a second shading member, being movable relative to the first shading member, to open and close the conveyance opening; and a shading-member moving device to move the second shading member so as to open and close the conveyance opening.
