Abstract

PROBLEM TO BE SOLVED: To provide an inexpensive image pickup device for an endoscope such that a CCD can be shielded against electromagnetic waves while adjustments of the eccentricity of a hermetic package holding the CCD are made possible. SOLUTION: A hermetic package 13 with a CCD held therein is held on its outer periphery by means of screws and eccentricity of the CCD can be adjusted by adjusting the screws. The shield layer 22 of a signal cable 5 connected to a ground line is electrically connected to the hermetic package 13 via the screws, a rear casing 33 and a contact member 16 to shield the CCD in the hermetic package 13 against electromagnetic waves. Since the contact member 16 slides against the outer periphery of the hermetic package 13, shielding is maintained even if the eccentricity is adjusted. This device can be constructed at low cost since no shields need to be provided newly around the hermetic package 13.

However, when the airtight package is held in a metal housing, most of the airtight package is generally made of metal. Since a frame is provided, there is a problem that weight and cost increase. In addition, if a structure is adopted in which a lightweight shield frame is provided in a resin-made housing for weight measures, the structure becomes complicated,
There has been a problem that an increase in the number of parts causes an increase in cost. The present invention has been made in view of the above circumstances, and enables at least protection of an image sensor from autoclave sterilization, and enables eccentricity adjustment of the image sensor to provide a good observation image without axis shift. It is an object of the present invention to provide an imaging device for an endoscope which enables to obtain the image pickup device, at least enables the image pickup device to be electromagnetically shielded, and can reduce the cost.
