Abstract
Abstract A portable computer terminal device. The terminal device includes data input means which is psychologically acceptable to physicians, lawyers and other professionals and includes a carrying case of unusually lightweight and compact construction. Data stored in the terminal device can be printed on multiple sheet business forms. The data can also be displayed by projecting a CRT light beam on a collapsible, high resolution screen carried in the terminal device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
274 words
A portable terminal device adapted to be carried to a site and to perform transaction operations by transmitting and receiving data to and from a central unit, said portable terminal device including (A) memory means for storing transaction defining data; (b) input means for inputting transaction defining data into said memory; (C) control means coupled to said memory means for determining (i) when sufficient transaction defining data is stored in said memory means for a transaction and said terminal device is in a transaction ready state, and (ii) when insufficient transaction defining data is stored in said memory means for a transaction and said terminal device is in a transaction inhibit state; (d) modem means for transmitting transaction defining data over a telephone line; (e) transaction means coupled to said memory means and said modem means for transmitting selected transaction defining data stored in said memory means through said modem means over telephone lines to said central unit when said control means determined said terminal device is in said transaction ready state; (f) a screen movable between at least two operative positions, (i) a first stored position for transport of said terminal device, and (ii) a second display position; (g) an optical system for projecting images of said transaction defining data onto said screen when said screen is in said display position; (h) means coupling said control means to said optical system for transferring transaction defining data from said memory means to said optical system for display on said screen; and, (i) a common portable housing for said memory means, input means, control means, modem means, transaction means, screen, optical system, and coupling means.
Claim 2
Dependent Claim
274 words
A portable terminal device adapted to be carried to a site and to perform transaction operations by transmitting and receiving data to and from a central unit, said portable terminal device including (A) memory means for storing transaction defining data; (b) input means for inputting transaction defining data into said memory; (C) control means coupled to said memory means for determining (i) when sufficient transaction defining data is stored in said memory means for a transaction and said terminal device is in a transaction ready state, and (ii) when insufficient transaction defining data is stored in said memory means for a transaction and said terminal device is in a transaction inhibit state; (d) modem means for transmitting transaction defining data over a telephone line; (e) transaction means coupled to said memory means and said modem means for transmitting selected transaction defining data stored in said memory means through said modem means over telephone lines to said central unit when said control means determined said terminal device is in said transaction ready state; (f) a screen movable between at least two operative positions, (i) a first stored position for transport of said terminal device, and (ii) a second display position; (g) an optical system for projecting images of said transaction defining data onto said screen when said screen is in said display position; (h) means coupling said control means to said optical system for transferring transaction defining data from said memory means to said optical system for display on said screen; and, (i) a common portable housing for said memory means, input means, control means, modem means, transaction means, screen, optical system, and coupling means.

Claim 5
Dependent Claim
305 words
A portable terminal device adapted to be carried to a site and to perform transaction operations by transmitting and receiving data to and from a central unit, said portable terminal device including (a) memory means for storing transaction defining data; (b) input means for inputting transaction defining data into said memory; (c) control means coupled to said memory means for determining (i) when sufficient transaction defining data is stored in said memory means for a transaction and said terminal device is in a transaction ready state, and (ii) when insufficient transaction defining data is stored in said memory means for a transaction and said terminal device is in a transaction inhibit state; (d) modem means for transmitting transaction defining data over a telephone line; (e) transaction means coupled to said memory means and said modem means for transmitting selected transaction defining data stored in said memory means through said modem means over telephone lines to said central unit when said control means determined said terminal device is in said transaction ready state; (f) a screen; (g) an optical system for projecting images of said transaction defining data onto said screen, said optical system including (i) image means for forming and projecting images of said transaction defining data, and (ii) at least one mirror for receiving said images and reflecting said images onto said screen, said mirror being movable between at least two operative positions, a first stored position for transport of said terminal device, and a second position for reflecting said images onto said screen; (h) means coupling said control means to said optical system for transferring transaction defining data from said memory means to said optical system for display on said screen; and, (i) a common portable housing for said memory means, input means, control means, modem means, screen, optical system, and coupling means.
Claim 6
