Abstract

Abstract A printer which includes a lower cabinet, and an upper cabinet pivotally connected at its one end to the lower cabinet for selective opening or closing with respect to the lower cabinet. The lower cabinet is provided with a holder plate to place on it a photosensitive and heat-sensitive paper having a heat-sensitive layer to be sensitized by light and visualized by heat, and a set of heat fixing rollers for visualizing images by imparting heat to the photo-sensitive and heat-sensitive paper, while the upper cabinet is provided with a transparent liquid crystal display panel of a light transmitting type disposed at a position to confront the photo-sensitive and heat-sensitive paper placed on the holder plate, upon closure of the upper cabinet with respect to the lower cabinet so as to display images corresponding to input as applied by an external operation or external signal and a light source for projecting light onto the transparent liquid crystal panel from its upper portion.

Independent Claim 162 words
A printer which comprises a lower cabinet, and an upper cabinet pivotally connected at its one end to said lower cabinet for selective opening or closing thereof with respect to the lower cabinet, said lower cabinet being provided with a holder plate to place thereon a photo-sensitive and heat-sensitive paper having a heat-sensitive layer to be sensitized by light and visualized by heat, and a set of heat fixing rollers for visualizing images by imparting heat to the photo-sensitive and heat-sensitive paper, said upper cabinet being provided with a transparent liquid crystal display panel of a light transmitting type disposed at a position to confront the photo-sensitive and heat-sensitive paper placed on said holder plate, upon closure of said upper cabinet with respect to said lower cabinet so as to display images corresponding to input as applied by an external operation or external signal, and a light source for projecting light onto said transparent liquid crystal panel from an upper portion thereof.
Claim 2
Dependent Claim 162 words
A printer which comprises a lower cabinet, and an upper cabinet pivotally connected at its one end to said lower cabinet for selective opening or closing thereof with respect to the lower cabinet, said lower cabinet being provided with a holder plate to place thereon a photo-sensitive and heat-sensitive paper having a heat-sensitive layer to be sensitized by light and visualized by heat, and a set of heat fixing rollers for visualizing images by imparting heat to the photo-sensitive and heat-sensitive paper, said upper cabinet being provided with a transparent liquid crystal display panel of a light transmitting type disposed at a position to confront the photo-sensitive and heat-sensitive paper placed on said holder plate, upon closure of said upper cabinet with respect to said lower cabinet so as to display images corresponding to input as applied by an external operation or external signal, and a light source for projecting light onto said transparent liquid crystal panel from an upper portion thereof.
Claim 3
Dependent Claim 44 words
A printer as claimed in claim 1, wherein said transparent liquid crystal display panel serves as a platform for directly writing information thereon by other writing means so as to print out the written information in composition with the information displayed on said panel.
Claim 4
Dependent Claim 48 words
A printer as claimed in claim 1, wherein said transparent liquid crystal display panel kept entirely transparent without any display, serves as a platform for placing thereon an original document prepared by writing information on a light-transmitting type sheet, thereby to utilize the printer as a copying apparatus.
