<p>PROBLEM TO BE SOLVED: To provide a stencil printer in which trouble of curling up of paper does not occur.SOLUTION: In a "double speed printing mode", a first piston pump 27 is driven at the timing corresponding to a paper tip of the first piece, a second piston pump 36 is driven at the timing corresponding to a paper tip of the second piece in a state where discharge to a switching claw member 63 is prohibited by an electromagnetic valve 60, and compressed air from both piston pumps is discharged from a paper discharge claw member twice at different timings. In a "double-sided printing mode", the second piston pump is driven at the timing corresponding to the paper tip of the paper on which surface printing has been finished while discharge of the compressed air to the paper discharge claw member being prohibited by the electromagnetic valve, the first piston pump is driven at the timing corresponding to the tip of the paper for rear surface printing in such a manner that the air is discharged from the paper discharge claw member, a flow passage is switched by the electromagnetic valve, and the compressed air from the second piston pump is switched to the switching claw member from the paper discharge claw member and is discharged.</p> |
