Abstract
A manual feed tray including a cover member pivotally supported at a lower end and assuming a storage position and a sheet feeding position; a sheet feeding platform situated at the lower end side of the cover member in the sheet feeding position, and mounted to the cover member so as to be capable of sliding toward the upper end side of the cover member and so as to leave a gap between the sheet feeding platform and itself; and an extension member assuming a storage position in which the extension member is stored in the gap between the sheet feeding table and the cover member and a pulled-out position.
Claims20
A manual feed tray comprising:
- a cover member pivotally supported at a lower end and having a storage position and a sheet feeding position;
- a sheet feeding platform located at the lower end side of the cover member in the sheet feeding position, and mounted to the cover member that is so constructed and arranged as to slide toward an upper end side of the cover member and to leave a gap between the sheet feeding platform and itself;
- an extension member which when stored is located in a gap between the sheet feeding platform and the cover member and when in a pulled-out position, a locking protrusion formed on the back surface on a distal end side of the extension member is hooked on an end edge of the upper end side of the cover member, and is pivotally retained so as to move away from the cover member, and
- when the cover member is pivoted from the sheet feeding position to the storage position, the sheet feeding platform is moved to the upper end side of the cover member by an extension member lock releasing mechanism interlocked with the pivoting of the cover member, pivots the extension member, and separates the locking protrusion of the extension member from the end edge of the upper end side of the cover member, with the extension member moving into the gap between the cover member and the sheet feeding platform so as to be stored therein.

- a discharge tray:
- the sheet conveying potion comprises a sheet conveying path and a manual feed tray;
- the manual feed tray comprising;
- a cover member pivotally supported at a lower end and having a storage position and a sheet feeding position;
- a sheet feeding platform located at the lower end side of the cover member in the sheet feeding position, and mounted to the cover member so as to be capable of sliding toward the upper end side of the cover member and so as to leave a gap between the sheet feeding platform and itself;
- and
- an extension member having a storage position in which the extension member is stored in the gap between the sheet feeding platform and the cover member and a pulled-out position wherein, in the pulled-out position, a locking protrusion formed on the back surface on a distal end side of the extension member is hooked on an end edge of the upper end side of the cover member, and is pivotally retained so as to move away from the cover member, and
- in the process in which the cover member is pivoted from the sheet feeding position to the storage position, the sheet feeding platform is moved to the upper end side of the cover member by an extension member lock releasing mechanism interlocked with the pivoting of the cover member, pivots the extension member, and separates the locking protrusion of the extension member from the end edge of the upper end side of the cover member, with the extension member moving into the gap between the cover member and the sheet feeding platform so as to be stored therein.

An image forming apparatus according to claim 19,
- wherein, in the pulled-out position the extension member guide grooves support the extension member substantially parallel to the front surface of the cover member and support a sheet stacking surface of the extension member to be situated substantially in the same plane as that of a sheet stacking surface of the sheet feeding stand.
A manual feed tray comprising:
- a cover member having a storage position and a sheet feeding position;
- a sheet feeding platform located at a lower end of the cover member in the sheet feeding position, and mounted to the cover member so as to slide toward an upper end side of the cover member and define a gap with the cover member;
- an extension member that can be stored in the gap and can be pulled-out, wherein a locking protrusion formed on the back surface on a distal end side of the extension member hooks on an upper end side of the cover member, and is pivotally retained so as to move away from the cover member, and
- when the cover member is pivoted from the sheet feeding position to the storage position, the sheet feeding platform is moved to the upper end side of the cover member with the pivoting of the cover member, and separates the locking protrusion of the extension member from the end edge of the upper end side of the cover member, with the extension member moving into the gap.
