Printing media feeding apparatus for printers |
摘要 |
A printer includes a printing portion and means for defining a sheet path along which a printing media passes through the printing portion. The sheet path defining means includes a pair of first feed rollers arranged upstream of the printing portion with respect to a normal feed direction of the printing media with the first rollers being adapted to be driven in the normal or a reverse direction. The first rollers further are driven at a predetermined speed with a predetermined speed force at least in a normal direction. A pair of second feed rollers is arranged downstream of the printing portion which are driven only in the normal direction at a feed speed slightly higher than the predetermined feed speed with a feed force slightly smaller than the predetermined feed force. The second rollers further are freely rotatable in the reverse direction.
