The present invention relates to an image forming device in which a sheet ejection part for stacking a recording sheet is disposed above an image forming part, and an image reading part is disposed above the sheet ejection part.
The ink cartridge 35 of this embodiment is disposed in the predetermined position that is distant from the disposed position of the printhead 28, in order to reduce the weight of the printhead 28 and enable high-speed printing of the printhead 28. The ink in the ink cartridge 35 is supplied to the printhead 28 by the operation of the pump (not illustrated) via the ink supply tube (not illustrated).
The composition in which the ink cartridge 35 is disposed at a different position than the disposed position of the printhead 28 enables the use of a large-scaled ink cartridge meeting the increased amount of consumption of the ink accompanied with high-speed printing of the printhead 28.
The ink cartridge 35 of this embodiment comprises two black (Bk) ink cartridges, a cyanogen (C) ink cartridge, a magenta (M) ink cartridge, and a yellow (Y) ink cartridge. In the ink cartridge mounting part 30, the five ink cartridges in total are accommodated.
As shown in FIG. 1, the front cover 51 provided in the front of the image forming device 1 is a foldaway cover which is opened when exchanging the ink cartridge 35. In the condition where the front cover 51 is opened to the outside, the ink cartridge 35 contained in the ink cartridge mounting part 30 appears, and it can be easily exchanged with a new ink cartridge 35.
The pivoted cover 15 forms a part of the sheet ejection tray, and this cover 15 is disposed in the sheet ejection part 3. Specifically, the cover 15 comprises the two plate members 15 a and 15 b, the rotation shaft which is fixed onto the bottom of the sheet ejection part 3 and pivotably supports the plate member 15 a thereon, and the rotation shaft 16 which is fixed on the plate member 15 a and pivotably supports the plate member 15 b on the plate member 15 a.
The plate members 15 a and 15 b are connected to each other by the rotation shaft 16. The plate member 15 a is rotatably supported on the sheet ejection tray such that the plate member 15 a is rotatable around the rotation shaft on the bottom of the sheet ejection part 3. When the cover 15 is opened, the two plate members 15 a and 15 b are folded up in the folded condition as indicated by the dotted line in FIG. 2. In this condition, the plate member 15 a is rotated around the rotation shaft on the bottom of the sheet ejection part 3 with the rotation shaft being used as the fulcrum.
The image forming device of FIG. 8 is configured so that the sheet ejection cover 44 capable of being opened and closed is disposed at a downstream position of the printing part 2 separate from the position of the cover 15 in the sheet ejection part 3, and an interlock switch 61 is disposed at the sheet ejection cover 44. When the sheet ejection cover 44 is opened, the opening of the cover 15 in the sheet ejection part 3 is inhibited by a result of detection of the opened condition of the sheet ejection cover 44 by the interlock switch 61. Other composition in this embodiment is the same as that of the image forming device of FIG. 2, and an explanation thereof will be omitted.
Further, the present application is based on and claims the benefit of priority of Japanese patent application No. 2004-159388, filed on May 28, 2004, the entire contents of which are hereby incorporated by reference.
an image forming part forming an image on a recording sheet;
a sheet ejection part provided above the image forming part and stacking the recording sheet on which the image is formed by the image forming part; and
wherein the sheet ejection part comprises a cover which is capable of being opened or closed to the sheet ejection part.
2. An image forming device according to claim 1 further comprising a sheet conveyance part conveying the recording sheet on which the image is formed by the image forming part, to the sheet ejection part via a conveyance passage.
3. An image forming device according to claim 1 wherein the sheet ejection part has a sheet ejection tray, and the cover constitutes a part of the sheet ejection tray.
4. An image forming device according to claim 2 wherein the sheet conveyance part is provided to invert the recording sheet on which the image is formed, so that the inverted recording sheet is conveyed to the sheet ejection part.
5. An image forming device according to claim 2 wherein the sheet conveyance part comprises a plurality of conveyance rollers disposed in a lower position, and a guide plate having a plurality of rowel-like rollers disposed to confront the plurality of conveyance rollers.
6. An image forming device according to claim 1 wherein the image forming part is an ink-jet printing part which prints an image on a recording sheet by performing an ink-jet printing process using an ink.
7. An image forming device according to claim 1 wherein the cover is a pivoted cover capable of being opened and closed by a rotating operation.
8. An image forming device according to claim 7 wherein the cover is a double-doored cover having a set of two pivoted plate members which are rotatable in mutually opposite directions.
9. An image forming device according to claim 1 wherein the cover is a sliding-door cover capable of being opened and closed by a slide operation.
10. An image forming device according to claim 1 wherein the cover comprises a pivoted cover capable of opened and closed by a rotating operation, and a sliding-door cover capable of being opened and closed by a slide operation.
11. An image forming device according to claim 1 wherein the cover comprises a set of two plate members, a first rotation shaft, and a second rotation shaft, the first rotation shaft being fixed to a bottom of the sheet ejection part and pivotably supporting one of the set of two plate members on the sheet ejection part bottom, and the second rotation shaft pivotably supporting the other of the set of two plate members on the one of the set of two plate members.
12. An image forming device according to claim 3 wherein the cover is a double-doored cover having a set of two door members which are rotatable in mutually opposite directions.
13. An image forming device according to claim 1 wherein a sheet ejection cover capable of being opened and closed is disposed at a downstream position of the image forming part separate from a position of the cover in the sheet ejection part, and an interlock switch is disposed at the sheet ejection cover, and wherein, when the sheet ejection cover is opened, opening of the cover in the sheet ejection part is inhibited by a result of detection of an opened condition of the sheet ejection cover by the interlock switch.
14. An image forming device according to claim 1 wherein a lighting is disposed near the image forming part, and when the cover is opened, the lighting illuminates a sheet conveyance passage near the image forming part.
15. An image forming device according to claim 1 wherein a mirror is disposed at a position where a lower portion of the sheet ejection part near the image forming part is visually recognizable from an opening which is formed when the cover is opened.
16. An image forming device according to claim 1 wherein the image reading part has a transparent region at a bottom position of the image reading part corresponding to a position of the cover in the sheet ejection part, and when the cover is set in the opened condition, a downstream portion of the image forming part is visually recognizable from the transparent region.
