Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CCD camera and, more particularly, to a structure for mounting components.

[0002]

2. Description of the Related Art FIG. 2A is a plan view of a conventional CCD.
FIG. 3B is a sectional view, and FIGS. 3A and 3B are explanatory views of a main part of a CCD camera showing an example of the related art. A conventional CCD camera using a CCD 2 having a lead 2b is a substrate 1
As shown in the figure, a distance of (A + B) is required between the lens 4 and the substrate 1 between the lens and the lower part of the lens 4, which hinders the thinning of the CCD camera. In addition, the entire lower mold surface of the CCD 2 used for the CCD camera is in close contact with the substrate 1 and is easily exposed to heat of other mounted components. As a result, there has been a problem that the temperature of the CCD 2 may increase, which may cause an increase in white scratches on the monitor screen.

Further, in a CCD camera, an optical filter 3 is used.
Although many use, a holder for fixing this is required. When the CCD 2 is mounted on the surface and the mounting area on the back surface of the substrate 1 is reduced, there is a problem that it is difficult to align the CCD 2 and the lens 4.

Japanese Patent Application Laid-Open No. 4-291886 discloses that
A metal plate formed at the center with an opening for receiving image light, disposed on the opposite side of the metal plate from the direction of incidence of the image light, and the image light is imaged on an imaging surface and the metal plate CCD by a CCD chip without a lead connected to a wiring portion formed on an insulating layer
Camera technology is disclosed. However, although this technology is useful for making the above-mentioned CCD camera thinner and preventing a rise in temperature, it is a technology that uses a CCD chip instead of a CCD camera that uses a CCD having leads, so that the position of the CCD and the lens and the optical filter can be adjusted. The problems in the manufacturing process, such as the mounting of, have not been solved.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a thinned CCD camera which uses a CCD having leads and facilitates an optical component mounting process.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and comprises a substrate having an opening through which image light is incident, and a substrate on the side opposite to the direction of incidence of the image light. CCD camera comprising: a CCD disposed in opposition to an opening and having leads connected to a wiring portion of a substrate; an optical filter disposed in front of the CCD; and a lens held by a holder. A flange provided on an outer periphery of the holder is brought into contact with the substrate, an end outer wall is formed so as to fit into an opening of the substrate, and an inner end wall of the holder is provided on an imaging surface side of the CCD. Is formed to form a storage section for storing.

[0007] A housing for housing the optical filter is provided on the inner wall of the holder above the imaging surface of the CCD.

Further, the storage section is formed so that the imaging surface of the CCD coincides with the center position of the lens.
