An apparatus in which a series of semiconductor chips electrically connected to each other are incorporated.

摘要

In an image reading apparatus, first and second semiconductor chips (111a, 111b) are arranged in series on atransparent insulative base. The semiconductor chips (111a, 111b) are covered by a protective layer and have conductive pads (321a, 321b) located both side of the series arrangement of the chips (111a, 111b). A traveling path in which a document (401) passes is defined on the protective layer between the pads (321a, 321b). <IMAGE>
