  • Publication number: 20050211877
    Abstract: A scanning system causes a reading light beam to scan a radiation image recording medium which records a radiation image thereon upon exposure to radiation carrying thereon the radiation image and from which a signal is read out according to the radiation image upon exposure to the reading light beam. A mobile body provided with a light source which emits a line-like reading light beam. A driver linearly moves the mobile body in a direction perpendicular to the longitudinal direction of the reading light beam and a holder holds the mobile body in a predetermined position.

  • Publication number: 20050116188
    Abstract: Load fluctuations caused by a change in moving direction of a linear motor 23 are prevented by affixing a belt 21 tensioned by a pair of pulleys 22 on the linear motor 23 for moving a reading light source portion 31 and affixing a counterweight 26 on the belt 21 at a portion diagonally opposite to the portion where the linear motor 23 is affixed with respect to the center axis of the belt 21. Further, damping devices (magnets 40 and 41) which impart a bias load to the counterweight 26 in the direction perpendicular to the tensioning direction of the belt 21 is provided, so that vibrations produced during traveling of the linear motor 23 is suppressed and accordingly the traveling accuracy of the linear motor 23 is increased.

  • Publication number: 20050017188
    Abstract: A solid-state radiation detector is provided which has an improved positional precision within a casing thereof while ensuring the shock resistance properties. A radiation cassette 1 comprises: a solid-state radiation detector 10 which is an image pickup device, a casing constituted by upper and lower shell halves 11 and 12 and accommodates therein the solid-state radiation detector and the like. Each of the upper and lower shell halves comprises: an outer frame 11a, 12a; an inner frame 11b, 12b, and a coupling member 11c, 12c for coupling the outer and inner frames. A space between the outer frame 11a, 12a and the inner frame 11b, 12b is filled with a shock absorbing material 13a, 13b, thereby imparting shock absorbency to the casing itself. The solid-state radiation detector 10 is rigidly secured to the inner frame 12b of the lower shell half 12.

  • Publication number: 20040227096
    Abstract: To improve the positional precision of a solid-state radiation detector within a casing of a radiation detecting cassette while ensuring a shock resistance. A radiation detecting cassette 1 comprises a casing constituted by upper and lower shell halves 11, 12 and a frame 13 fixed therein; and a solid-state radiation detector 10 which is an image pickup device. Four corners of the solid-state radiation detector 10 are sandwiched by plate springs 41 and 42 both of which are fixed to the frame 13.

  • Publication number: 20030020930
    Abstract: A method for forming a recording position adjusting pattern that is capable of correcting a recording position correctly, a method for adjusting the image recording position, and an image recording apparatus are provided. Corrected K color parallel bars are grouped into blocks each of which includes a certain number of bars and plural blocks are printed in block (180, 188), and the color parallel bars are printed between the K color parallel bars with tilt magnitude that is different for every block (182, 190). The optical detection unit detects the block having the highest density among the printed parallel bars (184, 192), the tilt magnitude of the detected block is set as the tilt magnitude of the color to thereby correct the tilt of the color (186, 194). The tilt of each color is corrected in the same manner.
