    • A continuous rotary actuator using a shape memory alloy has a simple structure, is small and light-weight, and has a high torque, which can lock the actuator against rotation during periods when the actuator is not energized. The continuous rotary actuator includes an inner drum rotating around an axis constituted by a rotating shaft. The inner drum is provided in an outer cylinder, wherein first and second shape memory alloy torsion springs, which are wound in opposite directions and which are unwound to recoil when electrically heated, are fixed between the outer cylinder and the inner drum, and wherein switching means for alternately switching the electrical heating according to the rotation angle of the inner drum are connected to the first and second shape memory alloy torsion springs.

    • In the image data processing of the digital copying machine (M), number of blocks Bn of image data in auxiliary scanning direction is set to the number of expanders (30, 31) Dn times a natural number N (N.times.Dn). This configuration makes it possible to utilize the (30, 31) expanders efficiently regardless of whether the image is to be rotated by 90.degree. or not when expanding compressed image data and printing the image. Thus such a situation that the expanders (30, 31) are forced to suspend the expanding operation does not occur, making it possible to start printing earlier and improve the printing speed. In the image reader 1 of the digital copying machine (M), when dividing image data corresponding to original document into a plurality of blocks and compressing the image data in the unit of block, length of the original document in the auxiliary scanning direction is estimated from width of the original document (size in principal scanning direction). Then by setting the partition of divided blocks based on the estimated document length, the image data can be compressed without waiting for the end of image data input for each block, not doing over the compression process even when the end of the original document is detected, thereby maximizing the image data compressing speed.
    • 在数字复印机(M)的图像数据处理中,辅助扫描方向上的图像数据的块数Bn被设置为自然数N(N×Dn)的扩展器(30,31)的数量Dn倍。 无论在扩展压缩图像数据和打印图像时是否要将图像旋转90°,这种配置使得可以有效地利用(30,31)扩展器。 因此,不会发生扩张器(30,31)被迫暂停膨胀操作的情况,从而可以更早地开始打印并提高打印速度。 在数字复印机(M)的图像读取器1中,当将与原稿对应的图像数据分割成多个块并以块为单位压缩图像数据时,估计原稿在辅助扫描方向上的长度 从原始文档的宽度(主扫描方向的大小)。 然后,通过基于所估计的文档长度来设定分割块的划分,可以压缩图像数据,而不用等待每个块输入的图像数据的结束,即使在检测到原始文档的结束时也不进行压缩处理 从而使图像数据压缩速度最大化。
