A method of manufacturing a semiconductor device that includes a junction field effect transistor, the junction field effect transistor including a semiconductor substrate of a first conductivity type, an epitaxial layer of the first conductivity type formed on the semiconductor substrate, a source region of the first conductivity type formed on a surface of the epitaxial layer, a channel region of the first conductivity type formed in a lower layer of the source region, a pair of trenches formed in the epitaxial layer so as to sandwich the source region therebetween, and a pair of gate regions of a second conductivity type, opposite to the first conductivity type, formed below a bottom of the pair of trenches.

Shunt wirings (12) in the form of a conductive light intercepting film which covers over vertical CCD registers and also serves to supply power, project into locations between adjacent photoelectric transducers (11) in the vertical direction, and the distance between the projecting portions of adjacent ones of the metal wirings is set to 0.2 .mu.m or less and is limited to a distance with which an electric field between adjacent ones of the metal wirings is 10.sup.7 V/cm or less and the adjacent metal wirings do not suffer from short-circuiting.

A photocopying apparatus is provided in which a moving area of a lens at the time of a magnification changing and that of an optical device such as a mirror unit overlap partly. At the time of the magnification changing, it is determined whether the optical device is positioned at a home position. When the optical device is not located at the home position, the lens is caused to move for the purpose of the magnification changing after the optical device is returned to the home position.
