    摘要: For a radiographic image detector which includes an imaging plane including two-dimensional matrix of pixel sections, each pixel section storing, when exposed to radiation, a charge according to amount of the radiation, and which is used to be exposed to radiation transmitted through the same subject each time the detector is shifted along a predetermined axis of shift, an inclination of the two-dimensional matrix relative to the axis of shift of the radiographic image detector is detected. The inclination is detected by applying radiation two times to the detector at different radiation application positions effected by the shift of the detector so that a common marker is imaged during each radiation application; carrying out a reading operation after each radiation application to acquire image data representing image information of the marker; and detecting the inclination based on a positional relationship between marker images represented by the image data.

    摘要: A printer and method of printing on a transfer medium utilizing thermoplastic magnetic ink. A thermal head selectively applies thermal energy to melt selected portions of the thermoplastic magnetic ink. A magnetic head substantially spatially fixed relative to the thermal head applies the magnetic force to the thermoplastic ink which causes the melted portions to be ejected onto the transfer medium. A strip of thermoplastic magnetic ink medium is positioned to slide between the thermal head and the transfer medium. The strip includes a base layer facing the thermal head and a magnetic thermoplastic ink layer facing the transfer medium. A first movement mechanism moves either the transfer medium or the thermal and magnetic heads relative to the other at a first speed. A second movement mechanism moves the magnetic thermoplastic ink medium strip relative to the magnetic and thermal heads at a second speed. The first and second speeds are unequal. The method includes moving a thermoplastic magnetic ink medium at a first speed relative to a thermal head and moving a magnetic head and thermal head at a second speed not equal to the first speed relative to the transfer medium. Selected portions of the thermoplastic magnetic ink medium are melted with a thermal print head. The melted ink from the thermoplastic magnetic ink medium is transferred to the transfer medium by a magnetic force applied by a magnetic head.
