Figure 1a is a plan view showing the configuration of the LED array according to the present invention, and Figure 1b is the light emitted from each light emitting part when every other LED element of the LED array shown in Figure 1a is lit. A luminescence distribution diagram showing the intensity distribution of
Figure 1c is the LED of the LED array shown in Figure 1a.
A display state diagram in which every other element is lit to produce an alternating black and white striped display on a sheet of paper, Figures 2a and b are schematic diagrams illustrating the differences between the LED array according to the present invention and a conventional LED array. Figure 3 shows the deviation of the distance between adjacent light emitting parts that straddle between adjacent chips with respect to the distance between adjacent light emitting parts within a chip, and the deviation of the distance between adjacent light emitting parts that straddle between adjacent chips. FIG. 4 is a schematic side sectional view of the main parts showing the configuration of a page printer to which the LED array according to the present invention can be applied; FIG. The figure is a schematic perspective view showing the configuration of a conventional long LED array.
, b, and c are schematic diagrams for explaining the influence when the interval between adjacent light emitting parts straddling adjacent chips is shorter than the interval between adjacent light emitting parts within the chip. C a ...chip, C b ...chip, l c ... light emitting part, l d ... light emitting part.
