対する位置度を調整した方がコスト的に有利である。In cameras using conventional silver halide film, the dimensions of the silver halide film relative to the camera body, that is, the position relative to the focal point, are determined by the processing accuracy of the camera body rail surface and the gap between the film pressure plate and the rail. It was something that On the other hand, in electronic still cameras, the image sensor is bonded to the image sensor substrate, and the dimensions of the image sensor and the attachment of the image sensor board to the camera body require surface processing precision. In terms of cost, it is more advantageous to move the image sensor substrate and adjust its position relative to the in-focus point.

ものがある。In this type of camera, methods for adjusting the position of the solid-state image pickup device are described in, for example, Japanese Utility Model Publication No. 161285/1985 and Japanese Utility Model Publication No. 9427/1983.

性と防埃において問題点があった。However, in these methods, electronic still cameras and conventional silver halide film cameras cannot be used.
Although it was designed to be replaced with an image sensor, there were problems with light-shielding and dust-proofing.

ｌｔあける必要がある。Figure 1 is a cross-sectional view of the structure of an example in which the film of a single-lens reflex silver halide camera is replaced with an image sensor.In this conventional example, in order to secure the amount of movement adjustment of the image sensor 1, the shutter 2 and A gap with some margin between the imaging cords 1'
It is necessary to open it.

Some devices include an optical low-pass filter 6 between the shutter 1 and the shutter 2, but in this case, the gap between the shutter 2 and the image sensor 1 becomes a little thicker, which exacerbates the above-mentioned drawbacks. Further, there is also the possibility that dust that has entered through this gap may adhere to the light receiving portion of the solid-state image pickup device 1 (in an optical form) and cause an adverse effect on the image. Furthermore, after the position adjustment process of the image sensor is completed, it may be possible to hide the gap with a sticker or the like to block light and prevent dust.
The number of man-hours increases significantly, which is not desirable.

Purpose of the Invention The present invention solves the drawbacks of these conventional techniques and realizes an electronic still camera that has a simple structure, has excellent light-shielding and dust-proof properties, and can easily adjust the movement of the image sensor. This is what I am trying to do.

いる。In these figures, 1 is an image sensor, 2 is a shutter,
A low-pass filter 6 is placed here. 4 is a substrate on which the image sensor 1 is mounted. Reference numeral 5 denotes an elastic light-shielding member installed between a member having an opening for image formation in the front part of the image sensor 1 (here, the shutter 2) and the light-receiving surface of the image sensor 1, and has a stepped cross section. Those exhibiting the following are used.

支柱７に基板４を完全に固定する。The light shielding member 5 is slightly bent due to its elasticity and is installed in a stretched state between the shutter 2 and the image sensor 1. 6 is a body, 7 is a support erected on this body, 8 is a fixing nut, and 9 is an adjustment nut. The substrate 4 to which the image sensor 1 is attached is guided by the support column 7 and is fixed between a fixing nut 8 and an adjusting nut 9. Here, by tightening the adjustment nut 9 against the force of the light shielding member 5 that urges the substrate 4 in the X direction, the substrate 4 is moved toward the lens side M, and vice versa.
By loosening the screws, the board 4 can be moved and adjusted to the side of the body, and by appropriately tightening or loosening the three sets of adjustment nuts 9, the imaging cord 1 can be adjusted.
The tilt of the lens relative to the optical axis and the focusing position can be adjusted. After completing the adjustment, tighten the fixing nut 8 and the board 4.
I'm going to sandwich it with the beggar adjustment nut 9, tighten it 5 tons,
The substrate 4 is completely fixed to the support 7.

ない。During such movement and adjustment of the image sensor board 4, even if the leg rainbow nut 9 is moved to move the board 4, the light shielding member 5 is elastically deformed with the movement, and the light shielding and dust prevention functions are always performed. can be done. Further, since the light shielding member 5 having a stepped cross section is used, the light shielding member deforms regularly into a so-called bellows shape, and the elastic body deforms into an irregular shape, and the 911 is reversed. There is no possibility that the light will enter the optical path.

果？もたせることができる。In addition, this shape acts as a kind of compression coil spring, and in addition to the elasticity of the light shielding member 5 itself, the biasing force to the image pickup element base &4 is further increased, and when the grinding nut 9 is moved with I-, It helps to accurately adjust the position of the board 4. Further, the stepped surface of the light shielding member 5 blocks harmful light (through the steps) and also functions as a light shielding line.The light shielding member 5 may be made of conductive material, for example, 4 conductive elastomer. Or, if a conductive paint is applied to the surface of the rubber light-shielding member 5, this will provide an electromagnetic or electrostatic shielding effect that protects the solid-state imaging system from airborne electromagnetic noise and electrostatic damage. It can be made to stand.
