Abstract
Abstract In a printer such as a laser beam printer utilized to print an image on a recording medium, an image transferring mechanism such as a photoconductive drum is disposed under the feed path of the recording medium so as to transfer an image such as a toner image onto the undersurface of the recording medium. The recording medium, on which the image is thus transferred is discharged and stacked with the image carrying side down in the proper order.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
158 words
A printer wherein an image is printed on a cutsheet type recording medium, which comprises: feed means for feeding said recording medium one by one along a predetermined feed path; image forming means disposed under said feed path for forming an image onto the undersurface of said recording medium fed by said feed means; and discharge means for discharging and stacking said recording medium with the image carrying surface down; wherein said feed means is arranged at the upper portion of one side of said printer while said discharge means is arranged at the lower portion of the other side of said printer; wherein said feed path linearly extends from said feed means to said discharge means with an inclination at a predetermined angle; wherein said printer comprises a body and a clamshell rockably mounted on said body; and wherein the upper surface of said body and the lower surface of said clamshell define said feed path therebetween.
Claim 2
Dependent Claim
158 words
A printer wherein an image is printed on a cutsheet type recording medium, which comprises: feed means for feeding said recording medium one by one along a predetermined feed path; image forming means disposed under said feed path for forming an image onto the undersurface of said recording medium fed by said feed means; and discharge means for discharging and stacking said recording medium with the image carrying surface down; wherein said feed means is arranged at the upper portion of one side of said printer while said discharge means is arranged at the lower portion of the other side of said printer; wherein said feed path linearly extends from said feed means to said discharge means with an inclination at a predetermined angle; wherein said printer comprises a body and a clamshell rockably mounted on said body; and wherein the upper surface of said body and the lower surface of said clamshell define said feed path therebetween.
