PURPOSE:To continuously type the double sides of a blank by swinging the sheet discharge side stocker of a printer for supplying a blank from the upper surface of a machine body and discharging the blank from the upper surface, and automatically overturning the discharged blank to return it to the blank supply position. CONSTITUTION:A blank supplied from a blank supply bed 10 is transferred by a platen 3 and auxiliary rollers 4, 5 while having the lower side typed by a printer 2, and sent between a blank discharge roller 6 and a blank discharge holder plate 7. Next, the blank passes through passages i, j and the rear end of the blank is dropped by its own weight as shown by the dotted line k and received in a stocker 9 to complete the one side typing. When both-side typing is needed, the stocker 9 is swung about a shaft 14 by a plunger 16 and shifted to a position shown by the dotted line in the drawing. The blank dropped through a passage k is overturned and transferred again between the auxiliary roller 4 and the platen 3 for typing 2. Thus, the back of blank can be also continuously typed.
