If the lens is tilted, the image formation position will change. If the flatness of the lens mounting surface decreases,
Focusing performance is degraded. With an inexpensive and simple holder,
Accurate positioning of a monocular lens is difficult.

さくすることができる。If the metal plate 26 is deformed due to fluctuations in the ambient temperature or heat generated from the LED array 12, the image forming performance will deteriorate. Particularly, in the case of the image device of the embodiment, the light from the LED array 12 is enlarged by the monocular lens 2 to form an image. Therefore, when the position of the monocular lens 2 is shifted by 5 μm or more due to thermal deformation, the transition between the arrays 12 and 12 is changed. White streaks and black streaks occur at positions corresponding to. However, the coefficient of thermal expansion of metals is generally about 1 to 2 × 10 −5 / ° C.,
It is smaller than the thermal expansion coefficient of plastic, which is 5 to 7 × 10 −5 / ° C., and by determining the horizontal position of the monocular lens 2 by the metal plate 26, it is possible to prevent deterioration of image quality due to thermal deformation. . In addition, in the embodiment, since the metal plate 26 is sandwiched between the two holders 16 and 32, the heat transmitted from the lens 2 to the plate 26 is released to the holders 16 and 32, and the thermal deformation can be further reduced. .

It is set to 0 and the compound lens 40 is mounted in units. As shown in FIG. 6, in the compound lens 40, the two lens portions 4 and 4 are integrated, the periphery thereof is surrounded by the ring portion 42, and the bottom surface of the ring portion 42 is used as the reference surface 44. Lens 4
In the formation of 0, for example, when resin is injected from the central portion, the resin uniformly flows to the left and right of the lens 40, and the left and right lens portions 4 and 4 can be formed symmetrically. On the other hand, for example, if the three lens portions 4 are integrated, it is difficult to uniformly form the central lens and the left and right lenses, and for example, the amount of resin flowing into the left and right lenses is different from that in the central lens. To do. If four or more lens parts 4 are provided, it becomes more difficult to form the lens parts 4 uniformly.
