Abstract
An image forming apparatus, including a chassis with an opening formed on one side thereof; a first placement section, on which a sheet inserted through the opening is placeable; a cover configured to be openable to expose and closable to cover the opening and configured to form, when in a position to expose the opening, an outer part of the first placement section outside the chassis; and a second placement section arranged in an upper position with respect to the first placement section, and on which a sheet inserted through the opening is placeable, is provided. The second placement section is detachably attached to the chassis through the opening.
Claims21
An image forming apparatus, comprising:
- a chassis with an opening formed on one side thereof;
- a first placement section, on which a sheet inserted through the opening is placeable;
- a cover configured to be openable to expose the opening and closable to cover the opening and configured to form, when in a position to expose the opening, an outer part of the first placement section outside the chassis;
- a second placement section arranged in an upper position with respect to the first placement section, and on which a sheet inserted through the opening is placeable;
- and
- a pickup roller configured to be disposed in the chassis on a side opposite from the cover across the opening and in an upper position with respect to the first placement section,
- wherein the second placement section is detachably attached to the chassis through the opening,
- wherein the second placement section comprises a first guiding part, the first guiding part extending in between the cover and the pickup roller along a sheet placement surface of the first placement section and comprising an end closer to the pickup roller and an end closer to the cover, and a second guiding part, the second guiding part extending from the end of the first guiding part closer to the pickup roller toward the pickup roller with inclination to be closer to the sheet placement surface of the first placement section,
- wherein the chassis comprises a guiding plane in a position between the pickup roller and the second guiding part of the second placement section, the guiding plane facing the second guiding part of the second placement section and extending with inclination toward the pickup roller to be closer to the sheet placement surface of the first placement section, and
- wherein an angle between the guiding plane of the chassis and the sheet placement surface of the first placement section is greater than an angle between a sheet placement surface of the second guiding part and the sheet placement surface of the first placement section.
