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.

A user replaceable flexible retractable antenna for use with a cordless phone comprises a conductive base pipe assembly having a screw terminal to be threadably received on a bracket assembly of the cordless phone, and a flexible antenna assembly having a conductive contact secured to one end slidably received within the base pipe assembly. The contact is maintained in sliding communication with the inner wall of the base pipe assembly and is connected to a conductive helix extending through the flexible antenna to define a conductive path between the distal end of the flexible antenna and the screw terminal of the base pipe assembly. The antenna can be easily removed from the cordless phone by rotating the base pipe assembly to disengage the screw terminal from the bracket assembly.
