Title: Radiographic information reader
Inventor: NAKAJIMA NOBUYOSHI
IPC: G03B42/02
Filed: 1987-08-27
Abstract: PURPOSE:To effectively reuse an accumulating type fluorescent material sheet by executing reading and erasing after taking out said sheet installing a light shielding means from a light-shielding bag in a sheet take-out part and housing said sheet into a light-shielding bag again in a sheet housing part. CONSTITUTION:The accumulating type fluorescent material sheet 1 housing in the light-shielding bag 2, on which radiograph information is accumulated and recorded, is taken out from the bag 2 by opening the bag 2. Excitation light irradiates said sheet 1 so as to generate stimulated phosphorescence light from said sheet 1 and the stimulated phosphorescence light is photoelectrically detected to read the radiograph information. After completing the reading, photoirradiation and/or heating is executed to said sheet 1 so as to erase the radiograph information remaining on said sheet 1 and said sheet 1 is housed in the light-shielding bag 2. Thus, the accumulating type fluorescent material sheet can be reused.

CONSTITUTION:A film 90 passes through the circumference of a tension roll 92 and is continuously wound on the circumference of a paper tube 70 of a first take-up shaft A, during this while turret plates 12a and 12b fitted with a second take-up shaft B are rotated as far as an angle alpha in a direction where the take-up shaft B comes nearer to the take-up shaft A, and when this take-up shaft A comes close to a fully wound state, they are rotated as far as the angle alpha in keeping relative relations between the take-up shaft A and a third take-up shaft C as well as the take-up shaft B and a fourth take-up shaft D left intact. Simultaneously with this rotation, the film 90 is cut by a cutter 94, and winding work is started by the take-up shaft B and after cutting, the take-up shafts A and C are further rotated as far as the angle alpha, thus the film is wound on the take-up shaft B. During this winding operation, the take-up shafts A and C are rotated as far as the angle alpha, and after the same cycle is repeated whereby film running length is shortened, thus rumples and positional slips are preventable.
