Abstract

Abstract A sheet guide adjusting apparatus for copy machines, phototelegraphic apparatuses, photo-engraving machines and the like, comprises a pair of sliding members supported on a machine body and able to move in a reciprocal manner to apply guides to the edges of sheets, and a drive mechanism mounted on the machine body and able to move in a reciprocal manner between and operatively interconnecting the sliding members. One of the sliding members and the drive mechanism being provided with clamping devices for clamping the sliding member and the drive mechanism in relative to the machine body, whereby the guides can be positioned to match the size of sheets by a center-standard method when the drive mechanism is fixed in a stable position in relation to the machine body, and the guides can be positioned to match the size of sheets by an edge-standard method when one of the sliding members is fixed in a stable position in relation to the machine body.
