A mobile, color printer capable of printing on letter-size plain paper and standard-size photo paper has a fold-up paper feeder that acts as a cover during travel. Such also serves as a storage tray for several sheets of paper to allow automatic feeding from a vertical stack. A slotted door hinged to the back of the printer, and under the hinges for the fold-up paper feeder/cover, can be flipped up or down. In the down position, a slot on the right side guides the user to feed in photo paper in the correct location. In the up position, letter-size plain paper has full-width access to the printing mechanism, and a sliding adjustable guide on the left allows letter, A4, and other size papers to be lightly corralled on both sides.
1. A mobile printer, comprising:
a printing mechanism for printing on a plurality of sizes of papers and sheet medias;
an enclosure in which the printing mechanism is disposed;
a hinged cover attached to the top rear of the enclosure and movable between a closed position and an open position, the cover in the open position providing for access of said plurality of sizes of papers and sheet medias to be input from the top to said printing mechanism;
a hinged door positioned between the hinged cover and the printing mechanism and capable of being flipped up when the hinged cover is open to allow a sheet of paper from a stack to enter; and
a slot disposed in the hinged door and providing for a limitation of the size and position that photo paper can enter the printing mechanism when the hinged door is flipped down, said photo paper being of lesser width than said sheet of paper.
Conventional printers can lay a lot of ink on a photo paper printout, and such ink can require a few extras seconds to dry and resist smudging. When more than one photo paper sheet is being printed, the later sheets output can smudge the top ones in the output stack. So it helps if the later sheets are gently dropped flat on the stack.
SUMMARY OF THE INVENTION
Briefly, a printer embodiment of the present invention is a mobile, color printer capable of printing on letter-size plain paper and standard-size photo paper. A fold-up paper feeder acts as a cover during travel, and as a storage tray for several sheets of paper to allow automatic feeding from a vertical stack. A slotted door hinged to the back of the printer, and under the hinges for the fold-up paper feeder/cover, can be flipped up or down. In the down position, a slot on the right side guides the user to feed in photo paper in the correct location. In the up position, letter-size plain paper has full-width access to the printing mechanism, and a sliding adjustable guide on the left allows letter, A4, and other size papers to be lightly corralled on both sides.
An advantage of the present invention is that a printer is provided that is easily portable.
Another advantage of the present invention is that a printer is provided that can accommodate various sizes of paper and photo card stock.
A further advantage of the present invention is that a printer is provided that is inexpensive to produce.

FIG. 1D is a perspective view of the mobile printer of FIG. 1B showing letter-sized paper being fed with the door gate opened and out of the way, and with the adjustable guide on the left set for this sized paper, and another piece of paper being output from the front after printing.
DETAILED DESCRIPTION OF THE EMBODIMENTS
FIG. 1A represents a mobile printer embodiment of the present invention, and is referred to herein by the general reference numeral 100. In one embodiment, the mobile printer
100 is generally about 13.3"×3.2"×6.5" and weighs about 4.2 pounds. It is capable of portable, battery powered operation. The mobile printer
100 includes a base
102 to which is hinged a paper-feeder/cover
104. In the closed position, the printer can be conveniently carried. Mobile printer
100 can accommodate plain and coated paper, labels, transparencies, Hagaki, card stock, envelopes, banner, and photo paper.
A paper support
106 can be extended to support the free end of paper loaded in the paper-feeder/cover
104. A hinged door
108 has a slot
110 that allows Hagaki or other photo papers to be fed in at an optimum offset from the right edge. This offset allows printing to commence much closer to the right edge of the photo paper, and it helps the stiffer photo paper to avoid a curling device inside before a paper output slot. Such curling device curls up the left and right edges of plain bond letter size paper so the paper will cantilever out while being output, and helps prevent smearing of a previously discharged page. A color ink cartridge and inkjet printhead
114 and a black ink cartridge and inkjet printhead
116 move left and right across the paper feeding-through during each print job. A right-edge guide
118 is visible and is in a fixed position. However, the right edge of slot
110 is offset to the left from this, and the slot controls how far to the right a photo paper can be loaded in.
In FIG. 1B, the hinged door
108 has been flipped up to get it out of the way for the printer to receive, e.g., plain-bond letter-size paper. An adjustable left-side guide
120 can now be seen. It is slide-mounted to the underside of the hinged door
108 and is used to lightly corral the left edge of the papers being input. The left-side guide
120 is preferably adjustable to accommodate at least letter-size paper sheets, A4-size paper sheets, and envelopes. The right-side fixed paper guide
118 lightly corrals in the right edge of such papers being input. The slot
110 no longer limits access to the printing zone beneath because it is folded up out of the way.
In FIG. 1C, a Hagaki or 4"×6" piece of photo paper
122 is shown as feeding through the slot
110. The finished, printed output is represented by a sheet
124.
In FIG. 1D, a letter-size sheet of paper
126 is shown as feeding directly into the printer with the door
108 folded up and the adjustable left side guide
120 properly set. The output is represented by a sheet
128 that has had its edges
130 and
132 curled up. Such curling is impressed on sheet
128 by a pair of curling lifts inside output slot
112.
In an alternative embodiment of the present invention, the pair of curling lifts inside output slot
112 are articulated such that they retract when door
108 is folded down to receive the Hagaki or 4"×6" piece of photo paper
122. Such photo paper is usually stiffer than bond paper
126, so the curling lifts are unnecessary. They can also significantly increase the force needed to output sheet
124 if not retracted.
The print media referred to herein includes plain paper, envelopes, coated paper, photo or glossy paper, transparency, card stock, index card, photo card, post card, hagaki card, labels, iron-on transfers, and any other suitable print media. Print media sizes useable with embodiments of the present invention include:
| |
| A4 (210 mm × 297 mm), |
| A5 (148 mm × 210 mm), |
| A6 Card (105 mm × 148 mm), |
