【発明の詳細な説明】
この発明は表示装置、たとえば光プリンタ等に使用され
る表示装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device, for example a display device used in an optical printer or the like.
近年、発光ダイオード・アレイを光源とする電子写真プ
リンタが開発され、実用化されつつある。In recent years, electrophotographic printers using light emitting diode arrays as light sources have been developed and are being put into practical use.
この電子写真プリンタに使用される発光ダイオード・ア
レイは１チツプに複数個の微小発光ダイオード素子（た
とえば１２８素子）が一定間隔（たとえば１００μｍ）
で配置されるものであり、プリンタの光源用の表示装置
としては、さらにこの発光ダイオード・アレイを複数個
（たとえば１６チツプ）縦続設置するのが通常である。The light emitting diode array used in this electrophotographic printer has multiple microscopic light emitting diode elements (for example, 128 elements) on one chip at regular intervals (for example, 100 μm).
As a display device for a light source of a printer, a plurality of such light emitting diode arrays (for example, 16 chips) are usually arranged in series.

するための位置調整が煩雑であるという欠点があった。A schematic diagram of this type of light emitting diode array is shown in FIG. The light emitting diode array 1 has a chip substrate 2
On the top, a plurality of display dots, that is, minute light emitting parts 3 are arranged with a predetermined pinch β1. Distance 11 from the tip of this light emitting diode array 1 to the most advanced micro light emitting section 3
2 is about the same as the pinch it1, and if the distance from the tip of the light emitting diode array 1 to the most advanced micro light emitting part 3 is 13, then 11 = 12 + 13 cannot be obtained, so the light emitting diode array 1 cannot be moved in the same direction. The pitches of the small light emitting parts of the entire display device cannot be made the same. Therefore, in a conventional display device for an optical printer, as shown in FIG. 2, the light emitting diode arrays 1 are alternately arranged in a cascade by shifting them in the width direction (up and down in the figure). The distance of the minute light emitting part is also pitch 1.
I made it equal to 1. However, in this display device, since the light emitting diode arrays 1 are alternately shifted in the width direction, the display dots cannot be made into one straight row line in the strict sense, and the width of the display device becomes large, and the display dots are arranged at the same pitch. The disadvantage is that the position adjustment is complicated.
この発明の目的は、上記した従来の表示装置の欠点を解
消し、表示装置の全ての表示ドツトのピンチを、横幅を

い表示装置を提供するにある。The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional display device, and to uniformly pinch all the display dots of the display device without increasing the width and without requiring labor for positioning. The object of the present invention is to provide a display device with high pinch accuracy.
