Abstract

A data capturing module combined with a portable data terminal of the hand-held type to record handwritten data. Using a digitized pad, the module can provide for direct input of handwritten data into the system, or a peripheral digital scanner can be employed to provide for data entry. Depending upon the particular application, the module therefore provides for data entry of handwritten text or graphics using the data terminal and other components of a portable data system to enter, display, print or otherwise communicate the handwritten data.

Claims

1. Apparatus for capturing handwritten data, comprising:

(a) a hand-held self-contained portable handwritten data capture assembly capable of receiving normally generated handwritten material, said assembly comprising an integral combination of a portable data terminal for processing data,

(b) a removable handwritten data receiving module removably connected to the data terminal and having a longitudinally extensive receiving surface for receiving a spatially extended sequence of information conveying handwritten data while the module is connected with the data terminal,

(c) means in said receiving module for reading the spatially extended sequence of information conveying handwritten data as applied to said receiving surface and entering the data into the data terminal, and

(d) said hand-held self-contained portable handwritten data capture assembly having a handgrip region comprising a bottom surface and adjoining side surfaces, providing a grip cross section such that the data capture assembly can be hand held with the operator'"'"'s hand in simultaneous contact with the bottom surface and the adjoining side surfaces of the data capture assembly.

2. The data capturing apparatus of claim 1 in which the means for reading the handwritten data is an optical digital scanner operatively connected with said portable data terminal and operative for optical reading of handwritten data on the receiving surface.

3. The data capturing apparatus of claim 1 in which the means for reading the handwritten data includes a digitizing pad operatively associated with said longitudinally extensive receiving surface.

4. The data capturing apparatus of claim 1 in which the data terminal is a hand-held unit.

5. The data capturing apparatus of claim 4 in which the module providing for entry of the handwritten data is quickly removable as a unit from the hand-held data terminal, the data terminal being fully operational for reading and processing data while separate from said module.

6. The data capturing apparatus of claim 1 wherein the data capture assembly is constructed to receive and store cursive handwritten data such as signatures.

7. In a hand-held portable data capture system, a data capture assembly of size and weight to be portable and to be held in one hand, said data capture assembly comprising:

(a) computerized processing means for computerized processing and storage of data,

(b) transmission means for the transmission of data between the computerized processing means and a site external to the data capture assembly,

(c) user interface means located on a surface of the data capture assembly and comprising input means for inputting handwritten information and for communicating said input to the computerized processing means, and display means for displaying data and instructions to an operator,

(d) integrated reading means for reading optical indicia located externally to the data capture assembly and for communicating an electronic representation of the indicia to the computerized processing means, and

(e) the data capture assembly having a cross section of a size capable of being held in one hand with the fingers of the gripping hand and the opposing thumb embracing opposite sides of the data capture assembly.

8. The hand-held portable data capture system of claim 7, wherein the input means is a digitizer input screen which digitizes the handwritten input information.

9. The hand-held portable data capture system of claim 8, wherein said input means is a transparent digitizer input screen, and said display means being behind said transparent digitizer input screen.

10. The hand-held portable data capture system of claim 7, wherein said display means is operative for displaying indicia for indicating a location at which handwritten entry of characters should begin on said input means.

11. The hand-held portable data capture system of claim 7, wherein said input means provides a screen responsive to stylus input of handwritten characters and which covers nearly an entire surface of the data capture assembly.

12. The hand-held portable data capture system of claim 7, further comprising information output means for repeating in a form intelligible to the operator the handwritten information input to said input means.

13. In the hand-held portable data capture system of claim 12, the information output means comprising graphical display means for displaying data in accordance with handwritten characters entered by the operator on the input means.
