Stacker unit

Abstract

Abstract PURPOSE:To stack media such as printed cut paper, after selecting its front/ reverse surface by making a stacker frame rotatable and direction-reversible and by providing a distributing lever whose movement is linked to the variation of the stacker frame operation. CONSTITUTION:In a stacker unit, a medium 17 in a hopper frame 29 is taken out one by one by means of a roller 30, and it is sent into a space between a guide 36 and a shoot 35 as well as between a platen 37 and a roller 38 by rollers 31 and 32 in order to be printed by a printing head 40. Thus printed medium 17 passes through a gap between guides 36 and 39 and is stacked on a stacker frame 20 by means of rollers 15 and 16. In this case, a supporter 21 of the said frame 20 is installed in such a manner that one end of the supporter 21 can be rotated by a pivot 22 on the tangential line common to the rollers 15 and 16, while a distributing lever 25 is also provided in such a way that it can be rotated by a shaft 27 on the said tangential line. With this contrivance, the stacker frame 20 and the distributing lever 25 rotate according to the arrow marks B or C respectively so that the front/reverse surface of the medium 17 can be selected.
