2. Description of the Related Art A conventional solid-state image pickup camera, for example, as shown in FIG. 4, has a front panel 2 attached to a front surface of a main body 1 and an inner peripheral surface of a convex portion 2a provided with an opening in the front panel. The first screw portion 2b is formed on the front panel 2, and the holder 3 holding the solid-state image sensor 3a is provided inside the front panel 2 so as to face the opening. On the other hand, the first screw portion 2b extends in the longitudinal direction of the outer peripheral surface. A lens holder 4 having a second screw portion 4a formed slightly apart from both ends is screwed, and a screw portion 4b formed on the inner peripheral surface of the lens holder 4 has a lens portion 5 provided with a C mount on one side. An adapter ring 6 having a locking portion (not shown) for locking, and a threaded portion 6a corresponding to the threaded portion 4b on the other side. The flange back was finely adjusted by the second screw portion 4a. Alternatively, in the above configuration, when locking the lens unit 5 having a CS mount, the adapter ring 6 is not used and the lens unit 5 is locked to the lens unit 5 on one side. It is locked to the lens holder 4 provided with a locking portion (not shown) for adjusting, and the flange back is finely adjusted by the first screw portion 2b and the second screw portion 4a. there were. The lens portion 5 of the C mount has a flange back distance of 17.526 mm, the lens portion 5 of the CS mount has a flange back distance of 12.5 mm, and there is a difference of about 5 mm in the flange back between the two. Therefore, as described above,
The adapter ring 6 is used for the lens portion 5 of the C mount, and the adapter ring 6 is not used for the lens portion 5 of the CS mount. However, in the above-mentioned configuration, since the lens portion 5 of the C mount and the lens portion 5 of the CS mount are supported, it is necessary to attach the expensive adapter ring 6 as an accessory. Since it must be stored when it is not used, there is a problem in terms of cost and usability. Further, when the adapter ring 6 is interposed between the lens holder 4 and the lens portion 5, there is a problem that the play of the screw portion is accumulated and the accuracy of the optical axis deteriorates. .
