    • A space-efficient imaging-plate-type X-ray diffraction apparatus featuring an expanded 2&thgr; goniometry range, high speed, high resolution, and design for convenient use is provided. The imaging-plate-type X-ray diffraction apparatus includes an X-ray measurement device composed of an X-ray optical system (5) and a goniometer (1) and is adapted to cause a single-crystal sample (3) to diffract X-rays. A cylindrical imaging plate (21) is disposed vertically so as to record X-rays diffracted by the sample (3), and covering a 2&thgr; goniometry range of −60° to +144°. A drive motor (11) and a transmission mechanism (12) transfer the cylindrical imaging plate vertically; and a rotary reader (20) is disposed so as to be coaxial with the transferred cylindrical imaging plate (21) and is adapted to read data of diffracted X-rays from an inner cylindrical surface of the cylindrical imaging plate (21).

    • A first lead electrode and a second lead electrode are disposed in such a manner as to be offset from each other in a horizontal scanning direction with a heating resistor interposed therebetween, and the width of a major portion of the heating resistor in the horizontal scanning direction is formed to be larger than the widths of the two lead electrodes in the same direction. It can be considered that peripheral portions of the heating resistor where their calorific value is essentially small are partially cut off together with parts of the lead electrodes at opposite ends thereof within the range that does not adversely affect the modulation of a heating area. Heat efficiency can be improved by supressing thermal diffusions in the peripheral portions where the calorific value is small, thereby contributing to recording of a clearer half-tone image.
    • 第一引线电极和第二引线电极以水平扫描方向彼此偏移的方式设置,其间插入有加热电阻器,并且加热电阻器的主要部分在水平扫描方向上的宽度 形成为大于两个引线电极在相同方向上的宽度。 可以认为,其发热量基本上小的加热电阻器的周边部分在不会对加热区域的调制产生不利影响的范围内与引线电极的相对端的部分部分地切断。 通过抑制发热量较小的周边部分的热扩散可以提高热效率,从而有助于记录更清晰的半色调图像。
