Claims

[Scope of utility model registration request]

In a hard copy device that uses cut sheets of two or more different sizes, there is a pair of upper and lower cassettes in which cut sheets of different sizes are stacked and mounted one above the other facing a conveyance roller, and the upper cassette is An upper paper feed roller fitted into an upper roller shaft that sends the cut paper at the bottom of the stack in the direction of the transport roller, and a feed roller that sends the cut paper at the top stacked in the lower cassette in the direction of the transport roller. The lower paper feed roller is fitted into the lower roller shaft, and is engaged with the upper or lower part of the drive gear, and is loosely inserted into the upper roller shaft or the lower roller shaft, and is connected to the upper roller shaft via the one-way clutch. Alternatively, a driven gear for rotating the lower roller shaft is provided, and the drive shaft into which the drive gear is fitted is rotated forward and backward as desired to select the upper cassette and the lower cassette and cut paper of a desired size. A paper feeding mechanism configured to feed the paper in the direction of the conveyance roller.
