Patent attributes
A sheet guide apparatus includes a transfer cylinder, delivery chains, and sheet guide structure. The transfer cylinder holds a sheet. The delivery chains hold the sheet received from the transfer cylinder and conveys the sheet along a first convey path which is at least substantially arcuate. The sheet guide structure guides the sheet conveyed by the delivery chains. The sheet guide structure includes a movable guide member and stationary guide member. The movable guide member is movable between positions close to and spaced apart from the first convey path. The stationary guide member is stationarily arranged at a position spaced apart from the first convey path. When the movable guide member is close to the first convey path, a thin-sheet guide surface having a continuous substantially arcuate section is formed by only the movable guide member. When the movable guide member is spaced apart from the first convey path, a thick-sheet guide surface having a continuous substantially arcuate section is formed by the movable and stationary guide members.
