摘要： A printer head capable of increasing intensity of dot-like light irradiated onto a record medium without requiring to increase a drive voltage or the number of printer heads arranged. The optical printer head includes a luminous element including two luminous dot arrays arranged in parallel to each other at a predetermined interval in a sub-scanning direction. The luminous dot arrays each are constituted of a plurality of luminous dots which have a dimension in the sub-scanning direction increased by a predetermined magnification as compared with that in a main scanning direction and are spaced from each other at identical intervals in the main scanning direction. The luminous dots of the two luminous dot arrays are arranged in an offset manner while being deviated from each other in the main scanning direction by a distance equal to the dimension thereof in the main scanning direction. Also, a reduction optical system is arranged for carrying out irradiation of light emitted from the luminous dots while reducing a dimension of the light in the sub-scanning direction by a reciprocal of the predetermined magnification.

摘要翻译： 一种打印头，能够增加照射到记录介质上的点状光的强度，而不需要增加驱动电压或打印头排列的数量。 光学打印机头包括在副扫描方向上以预定间隔彼此平行地布置的两个发光点阵列的发光元件。 发光点阵列由多个发光点构成，多个发光点在副扫描方向上与主扫描方向相比增加了预定的倍数，并且在主扫描中以相同的间隔彼此间隔开 方向。 两个发光点阵列的发光点以偏移方式布置，同时在主扫描方向上彼此偏离与其在主扫描方向上的尺寸相等的距离。 此外，还原光学系统被布置成用于执行从发光点发射的光的照射，同时通过预定倍率的倒数减小副扫描方向上的光的尺寸。
