Abstract
A printing apparatus for exposing works, such as printed circuit boards, to light uses a pallet in which a number of works and at least one associated mask are stored. The works are located in stacked relation to one another. The mask is located above the works. The printing apparatus comprises an exposure device including light sources and transparent plates, an admitting device for holding the pallet in an access position and for holding the uppermost one of the mask and works in the pallet at a certain height, a conveying device including a rail extending from the access position to a takeout position past an exposure position at which an exposure operation is performed, and an attraction device including attraction plates having a number of attraction pads mounted to the underside thereof for attracting and holding the mask and works. Each attraction plate is vertically movable while keeping a horizontal posture. The conveying device further includes two cases one of which can reciprocate between the access position and the exposure position along the rail, the other being capable of reciprocating between the exposure position and the takeout position along the rail.
