トと撮像光学系の正確な位置合せが必要である。The conventional mounting mechanism and mounting method for an image pickup device described above have the following drawbacks. (1) After assembling the image sensor holder etc., it is essential to adjust the optical axis and the image tilt. (2) An accurate adjustment chart is essential. (3) In order to obtain an accurate adjustment result, it is necessary to accurately align the adjustment chart and the image pickup optical system.

く、切削加工によるコスト上昇も生じる。(4) In the conventional configuration, the assembling direction is not one direction {the filter holder 5 is attached in the direction of the arrow α and the image pickup device holder 6 is attached in the direction of the arrow β}, which is not suitable for the automation of the assembly. . (5) Since the relative positioning between the image sensor 4 and the optical filter 3 is not performed, the effect of the optical filter 3 tends to vary. (6) Since the image pickup device holder 6 is made of aluminum die-cast, it is heavy and the cost increases due to cutting.

である。(7) Since the shape of the image sensor holder 6 is point-symmetrical as shown in the plan view of FIG. 4, it is difficult to notice even if the temporary product number 4a is written on the image sensor 4, etc., and the image sensor 4 is imaged. An operator may attach the lens in the opposite direction (upside down) from the normal direction. (8) With the above-mentioned configuration, in which the optical axis and the image tilt adjustment are unnecessary by providing the reference for the package of the image sensor 4, the adjustment accuracy is poor because the dimensional accuracy of the package is poor, and The package is large and inconvenient. (9) When trouble occurs in the image pickup element 4, the image pickup lens, etc., the operator must disassemble and repair parts such as parts replacement. However, for the subsequent optical axis adjustment and image tilt adjustment, the adjustment is performed. It is necessary to use the equipment and equipment for the work, and the work is troublesome and difficult.

詳細に説明する。As is clear from a comparison between FIG. 1 and FIG. 4, in the present invention, the shapes of the filter holder 5, the image pickup element holder 6, and the mount portion 2 of the lens housing 1 have the greatest feature. . That is, the shape of the image pickup device holder 6 which is the image pickup device mounting member is a very simplified flat plate shape. In particular, since the image pickup device holder 6 is formed of an engineer plastic and a sheet metal of aluminum, the image pickup device holder 6 is lightened and can be cut. Since it is unnecessary, the cost could be reduced. Hereinafter, the shapes of these members will be described in detail with reference to FIG.

となった。First, the image pickup device holder 6 includes the image pickup device 4
Slot 6 for inserting the plurality of pin terminal groups 4b, 4c respectively
b and 6c are provided, and large and small round holes 11e and 11f are provided in the vicinity of the long holes 6b and 6c. on the other hand,
Large and small circular bosses 12e and 12f are provided in the filter holder 5 at positions facing the round holes 11e and 11f, respectively.
Moreover, since the notches 5a and 6a are formed at the same position on one side of the holders 5 and 6, respectively, the operator can easily recognize the vertical direction. If a mistake is made, the large circular boss 12e will not fit into the smaller round hole 11f, so that the misplacement can be immediately recognized. Similarly, a round hole 11g and an elliptical hole (or an elongated hole) 11h are formed in the mount portion 2 of the lens housing 1, and the filter holder 5 is provided at a position facing the round hole 11g and the elliptical hole 11h. , Large and small circular bosses 12g and 12h that cannot be fitted in the opposite combination are provided. Due to the above mounting direction error prevention structure,
There is no mistake in the mounting direction of the image pickup element 4 with respect to the image pickup lens.

The window 2c for fitting and holding the optical filter 3 is the window 5c for fitting and holding the spacer rubber 7 on the optical filter holder 5.
However, since each of them is formed, the optical filter 3 can be accurately attached to the optical filter holder 5 without any error in the twisting direction. As a result, in cooperation with the mounting direction error prevention structure, optical axis adjustment and image tilt adjustment after temporary fixing in the conventional example are not required, and high adjustment accuracy can be obtained.

a and 2b are formed to have a predetermined height, and the screw holes 2a and 2b of the image pickup device holder 6 and the filter holder 5 are formed.
Round holes 11a to 11d are bored at positions facing each other. Then, the image pickup device holder 6 to which the image pickup device 4 is attached and the filter holder 5 are overlapped, and the spacer rubber 7
Also, the optical filter 3 is interposed between the image pickup device 4 and the mount portion 2, and the holders 5 and 6 are simultaneously screwed into the screws 9a and 9a.
In the configuration shown in FIG. 10b, the screw holes 2a and 2b are screwed from the direction of the arrow γ through the round holes 11a to 11d, respectively. As a result, both holders 5 and 6 are attached to the mount portion 2 from the same direction at the same time, so that the number of fastening points is reduced and the assembly and the automation thereof are greatly facilitated.

In the mounting method of the present invention, the camera 10 for image processing is used instead of using the adjustment chart or the monitor device such as CRT in the conventional method. In order to recognize the image of the image sensor 4 using the camera 10, first, the effective pixel surface of the image sensor 4 is recognized from the image obtained by the camera 10. Next, the recognized effective pixel surface is attached to the holder 6 which is a member for attaching the image pickup device.
Move to the regular position with respect to the position reference. With the effective pixel surface positioned, the image sensor 4 is attached to the image sensor holder 6 with an adhesive or the like to form an image sensor sub-assembly.

結像面位置の移動への対応が可能となる。With the mounting mechanism and the mounting (assembling) method as described above, the image pickup device 4 itself can be fixed by adjusting the optical axis and the image tilt with respect to the position reference, and high adjustment accuracy can be obtained. Therefore, the image sensor 4 and the optical filter 3
The relative position with and became more accurate, and the variation in the effect due to the optical filter was reduced. Further, in the case where a problem occurs in the image pickup device 4, the image pickup lens, etc., it is not necessary to use the automatic assembling apparatus or the adjustment chart, and the operator disassembles and repairs such as parts replacement. Attach the sub-assembly together with the optical filter holder 5 to the screw hole 2 of the mount 2.
Since the screws 9c and 9d may be screwed onto the a and 2b and fixed, it is possible to easily assemble. Therefore, the image plane position moves in the optical axis direction because the design value of the optical filter is different because the number of pixels or the spectral characteristic of the image sensor is different, or because the package of the image sensor is different, If the optical filter holder 5 is designed according to the position of the image plane,
It is possible to deal with the movement of the image plane position.
