15b) and are provided.

[Example] As shown in Figs. 1 to 3, the solid-state imaging device 1 is held by a frame-shaped protective frame 2. The holding frame 2 integrally holds the solid-state image pickup device 1 by a mounting means (not shown). For example, two frame members formed in a substantially L shape as the holding frame are provided on the outer periphery of the solid-state image pickup device 1. A spring member may be used for the attachment. The holding frame 2 holding the solid-state imaging device 1 includes a frame-shaped bracket 7
It is supported via support pins 8, 9, 10 and leaf springs 11, 12.

That is, in the periphery of the holding frame 2, the rectangular space portion 13 of the bracket 7 is formed to be slightly larger than the outer shape of the holding frame 2, and between the left side surface of the protection frame 2 and the bracket 7 in FIG. Protective frame 2 against bracket 7
A leaf spring 11 for urging the protective frame 2 to the right is interposed, and the tip end of a support pin 8 screwed and attached to the bracket 7 abuts on the right side surface of the protective frame 2 to move the protective frame 2 in the horizontal left-right direction. The position with respect to X is regulated. In addition, a leaf spring 12 for urging the protective frame 2 upward with respect to the bracket 7 is interposed in the gap between the lower side surface of the protective frame 2 and the bracket 7, and The ends of the two support pins 9 and 10 screwed onto the bracket 7 come into contact with each other to regulate the position of the protective frame 2 in the vertical vertical direction Y. Therefore, by adjusting the degree of screwing of the support pin 8 with respect to the bracket 7, the position of the solid-state imaging device 1 integrated with the protective frame 2 in the left-right direction X can be adjusted, and the support pin 9 with respect to the bracket 7 can be adjusted. The position of the solid-state image pickup device 1 in the vertical direction Y can be adjusted by adjusting the degree of screwing of the support pins 9 and 10, and the degree of screwing of the support pin 9 and the support pin 10 with respect to the bracket 7 can be appropriately adjusted. The solid-state imaging device 1 can be rotationally adjusted with respect to the rotation direction θ about the optical axis O.

In addition, in FIG. 2, the left and lower frame portions of the bracket 7 slightly extend in opposite directions, and screw holes 7a and 7b are formed on the back surfaces of the extended portions, respectively. The rear surface of the bracket 7 in which these screw holes 7a and 7b are formed is a reference surface 7e (see FIG. 4).

When arranging the protective frame 2 holding the solid-state image sensor 1 in the space 13 of the bracket 7, the front plate 7d forming the window 7c of the bracket 7 in front of the space 13 and the protective frame 2 are A leaf spring 16 for biasing the protective frame 2 in the rearward direction is interposed between the two. Then, in this state, the adjusting plate 14 is arranged to face the reference surface 7e, and the adjusting plate 14 is attached to the reference surface 7e by screwing the adjusting screws 15a and 15b into the screw holes 7a and 7b, respectively. (See Figures 1, 3 and 4). The adjusting plate 14 is provided with a hole 14a for passing the lead terminal 1a of the solid-state image pickup device 1. Lead terminal 1 of solid-state image sensor 1
The tip of a is connected to, for example, the electric circuit board 17 (see FIG. 3). The adjusting plate 14 is provided with the adjusting screws 15a, 15 described above.
By adjusting b appropriately, the position of the distance from the reference surface 7e can be adjusted in the adjustment portion.

By the way, as shown in FIGS. 2 to 5, at a corner of the bracket 7 on the lower left side when viewed from the front, as shown in FIGS. 2 to 5, one corner 14b of the adjusting plate 14 is sandwiched to support and regulate it. An arch-shaped engaging portion 18 is provided. As is clear from FIGS. 2 to 5, the arch-shaped engaging portion 18 is immovable so that the relative position of the bracket 7 to the reference surface 7e is fixed. Therefore, one corner of the adjustment plate 14
As described above, the adjusting plate 14 is adjusted with respect to the reference surface 7e of the bracket 7 with the adjusting screw 15 in the state where the engaging member 18 is sandwiched by the adjusting plate 15.
When mounted using a and 15b, the distance from the reference surface 7e of the adjusting plate 14 changes depending on the screwing degree of the adjusting screws 15a and 15b with respect to the screw holes 7a and 7b at the positions of the adjusting screws 15a and 15b. However, the position of the engaging portion 18 is restricted to a constant distance.

Therefore, as shown in FIG. 4, one adjustment screw 15a
Position of the engaging portion 18 and the other adjusting screw 15b
When the adjusting plate 14 tilts back and forth with respect to the reference surface 7e about the straight line Lx connecting the position of the position of the engaging portion 18, the position of the engaging portion 18 and the adjusting screw 15a of the one side when adjusting the other adjusting screw 15b. The adjusting plate 14 tilts back and forth with respect to the reference plane 7e with the straight line Ly connecting the position of and as the center of rotation. If this adjustment plate 14 moves,
The solid-state image pickup device 1 integrated with the protective frame 2 which is constantly urged in the direction of the adjusting plate 14 by the leaf spring 16 also moves. Therefore, the inclination of the light receiving surface of the solid-state image sensor 1 integrated with the protective frame 2 via the adjusting plate 14 with respect to the reference surface 7e can be adjusted by adjusting the one adjusting screw 15a, 15b.

Incidentally, the engaging portion 18, it is desirable to regulate one corner portion 14b of the adjusting plate 14 at a point where the straight line Lx and the straight line Ly intersect so that the rotation fulcrum position of the same portion does not change as much as possible. As shown in FIGS. 6 (A) and 6 (B), an engaging portion 28 having a protrusion 28a at a point where the straight line Lx and the straight line Ly intersect is used, and the adjusting plate 14 is also fitted to the protrusion 28a. You may make it form the recessed part 14c which fits.
Alternatively, as shown in FIGS. 7A and 7B, the engaging portion 38 may be shaped so as to close and cover the corner 14b of the adjusting plate 14, or as shown in FIG. The engaging portion 48 may be formed by cutting out the middle of the engaging portion 18.

[Advantages of the Invention] As described above, according to the present invention, the configuration is very simple as compared with the conventional device, and the workability of assembling is also very good.
