Abstract
The invention provides a sheet feed cassette for holding various sizes of sheets to be fed to an image recording apparatus in a feed direction. The cassette comprises a first casing having a sheet placement area, and a second casing slidably connected to the first casing for expanding the area. The first casing is detachably mounted on the image recording apparatus.
Claims5
A sheet feed cassette for holding various sizes of sheets to be fed to an image recording apparatus in a feed direction, said cassette comprising:
- a first casing having a sheet placement area,
- a second casing slidably connected to the first casing for expanding the area, said first casing being detachably mounted on said image recording apparatus,
- a width regulator for regulating placement of said sheets in a perpendicular direction to said feed direction,
- wherein the width regulator comprises a pair of width regulation plates, said plates being slidable in said perpendicular direction,
- a first moving device for moving the pair of plates symmetrically and simultaneously,
- a second moving device for moving the second casing in cooperation with the first moving device so that each of said width regulator and said second casing moves a predetermined distance simultaneously when either one of said width regulator or said second casing is moved,
- wherein the first moving device comprises a first rack gear and a first pinion gear, and the second moving device comprises a second rack gear and a second pinion gear, wherein said first rack gear engages said first pinion gear, and the first pinion gear and the second pinion gear have a common axis of rotation.
A sheet feed cassette for holding various sizes of sheets to be fed to an image recording apparatus in a feed direction, said cassettes comprising
- a casing having a sheet placement area on which a pile of sheets is placed;
- a width regulating plate to regulate placement of the sheets in a width direction which is perpendicular to a sheet feed direction;
- a first moving device to move the width regulating plate, including a first rack gear and a firs pinion gear;
- a back edge regulating plate to regulate placement of the sheets in the sheet feed direction;
- and
- a second moving device to move the back edge regulating plate including a second rack gear and a second pinion gear;
- wherein the first pinion gear and the second pinion gear have a common axis of rotation so that each of said width regulating plate and said back edge regulating plate moves a predetermined distance simultaneously when one of said width regulating plate or said back edge regulating plate is moved.
