Title:
RADIOGRAPHIC IMAGE INFORMATION RECORDING AND READING DEVICE
Document Type and Number:
Japanese Patent JPS6292665
Kind Code:
A
Abstract:
PURPOSE:To miniaturize a device remarkably by projecting a storage type phosphor sheet from an enclosure to the outside at a picture read time and to eliminate a storage type phosphor sheet carrying space for exciting light subscanning in the enclosure. CONSTITUTION:The device consists of a main body 20 and a radiation source storage part 30. A storage type phosphor sheet 22 is arranged in the enclosure 25 of the main body 20. When the sheet 22 is moved by a driving roll 58 after the radiographic image information of a person 34 to be examined is stored and recorded on the sheet 22, the sheet 22 is projected out of the enclosure 25 through the aperture 25a of the enclosure 25. Then, a laser light source 51 and an optical polarizer 56 are operated to scan a laser light 52 on the sheet 22 in a position near the aperture 25a, and most of the sheet 22 is projected out of the enclosure 25 when picture read is terminated. Next, the driving roll 58 is rotated reversely to return the sheet 22 to an exposure position, namely, a position facing a photographing base in the enclosure 25. The sheet 22 passes an erasing part 70 provided in a position near the aperture 25a at this time and the picture of the sheet is erased.
