  • Patent number: 4886968
    Abstract: A radiation image read-out apparatus comprises a sheet holding device for holding an image-recorded stimulable phosphor sheet on a cylindrical surface, and a spinner provided with a deflection mirror for reflecting stimulating rays coming from a semi-transparent mirror to the stimulable phosphor sheet, and a condensing lens for converging the reflected stimulating rays on the stimulable phosphor sheet. The spinner rotates the deflection mirror and the condensing lens to scan the stimulating rays in a main scanning direction on the stimulable phosphor sheet, and the sheet holding device is moved normal to the main scanning direction. A detection lens converges light emitted by the stimulable phosphor sheet upon exposure to the stimulating rays, passing through the condensing lens and coming from the semi-transparent mirror.

  • Patent number: 4883960
    Abstract: In a radiation-type diagnosis apparatus, a plurality of imaging plates, each provided with bar codes, are received in a magazine and the magazine is set in a first storage section of the apparatus. In the first storage section, a photo detector for detecting the presence or absence of the bar code is located above the magazine to determine whether or not the imaging plate is positioned currently in the magazine. When the imaging plate is correctly located in the magazine, the imaging plate is transfer to a recording region in which an image of a region of interest is photographed.
