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

1. 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 through communication means, said portable terminal device comprising:

(a) means for inputting transaction defining data;

3. The portable terminal device of claim 1 including

(a) a screen;

(b) an optical system for projecting images onto said screen; and

,

(c) 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.

2. (b) memory means for storing transaction defining data entered by said input means;

(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) transmission means coupled to said memory means for transmitting selected transaction defining data stored in said memory means through said communication means to said central unit when said control means determines said terminal device is in said transaction ready state;

(e) a housing for said input, memory, transmission and control means, said housing including at least one wall having

(i) an intermediate layer of plastic material,

(ii) an outer and inner layer of corrugated cardboard material, and

(iii) an outer layer of tensioned resilient material adjacent and covering said outer layer of corrugated cardboard,

said plastic material

being resilient when a force is applied against a selected area of said plastic material and said plastic material can flex to resist said force generally without permanent deformation of said plastic material, and

being readily compressed and permanently deformed when a force is applied to said plastic material and said material cannot flex to resist said force,

said outer and inner layers of cardboard being biased with respect to one another.
