Abstract
Abstract To provide an image sensor which enables internally mounted electronic parts such as a light receiving element to be protected against adverse affection at assembly of the image sensor, electronic parts in a control block to be easily adjusted after assembly, and the control block to be replaced easily and at low cost conforming to various electrical characteristic requirements, a part of a board containing a light emitting element and/or a light receiving element disposed within a frame is projected from the frame, having a glass cover on the top and side boards on both sides and terminals on one side of a connection terminal block are soldered to the projection of the board and terminals on the other side are soldered to a hybrid unit used as a control block for controlling electric signals of internally mounted electronic parts such as the light emitting and receiving elements. The hybrid unit consists of an electronic parts package and a board to which the package is soldered.
