Abstract

A small lightweight hand-held data processing terminal is provided with several visible field display registers, one entry register, and a keyboard. When used by a route salesman, for example, the salesman initially enters information from the keyboard into the entry register, and then upon verifying that the information is accurate the salesman shifts the information up to the individual field registers which might for example relate to product code information, the number of units which are being purchased or sold, the type of transaction whether it is cash, check, credit card, or the like, and other desired information. The transaction information is initially entered in the entry register and is then shifted up to the appropriate field register. Finally, the customer identification number is entered in the entry register, the entire transactional entry is rechecked visually, and then entered into storage. The hand-held terminal is provided with a CPU (Central Processing Unit) which permits simple mathematical computations such as multiplying the price by the number of units being purchased, giving a suitable discount and the like. The data processing terminal also keeps track of the time of day, and records the time of day as each transaction is entered from the visible display registers into the random access storage of the unit. The keyboard is provided with a recall key to recover the last entered data. Function keys are also provided for selecting other data from storage and displaying it in the field and entry registers from which it was originally obtained.

Claims

1. A hand-held data processing and data logging terminal system comprising:

a plurality of field registers, and a corresponding plurality of associated visible display means for exhibiting the data included in each said field register;

an entry register and a corresponding associated visible display means for exhibiting numbers included in said entry register;

said entry register and associated visible display means being separate from said field registers and associated displays;

a keyboard;

means for entering data from said keyboard into said entry register, and concurrently displaying said data in said associated visible display;

a plurality of individual switching means mounted on the face of said hand-held data processing system and adjacent each of said field registers for selectively shifting information from said entry register directly into the selected one of said field registers for immediate display in the visible display associated with each field register;

housing means for mounting said registers, display means, keyboard, data shifting means and switching means into a lightweight hand-held unit;

a memory unit;

means for entering information stored in said field registers into said memory unit;

means for initially entering a key predetermined multidigit number and a number indicating the time of day into said entry register;

means for continuously updating said time of day information;

decoding means responsive to the entry of said predetermined multidigit number and said number representing the time of day for enabling the transfer of information from said field registers to said memory unit; and

means for automatically storing said time of day information with information transferred from said field registers to said memory unit.

2. A system as defind in claim 1 further comprising:

switching means for storing all of the data displayed in said registers, and simultaneously clearing said visible displays.

3. A system as defined in claim 2 further comprising random access memory means for receving and storing said data.

4. A system as defined in claim 1 further comprising:

means for initially shifting data from said entry register to a first one of said field registers and displaying said data in the visible display associated with said first field register;

means for making additional entries into said entry register while said initial data remains displayed in said display associated with said first field register; and

means for subsequently shifting the newly entered data from said entry register to a second one of said field registers and displaying the newly entered data in the display associated with the second field register while continuing to display the initial data in said display associated with said first field register.

5. A data logging system as defined in claim 2 further comprising:

means for recalling selected data from storage and displaying said data in the respective field display means from which the data was drawn.

6. A system as defined in claim 5 including means for entering data into said entry register;

and means for recalling and displaying information which has previously been stored based on the data entered in said entry register.

7. A system as defined in claim 1 further comprising:

central processing unit means for performing arithmetic operations on information entered in said data logging system;

read only memory means for controlling the sequence of operation of said data processing terminal system; and

random access memory means for storing information from said visible displays.

8. A system as defined in claim 2 further comprisng:

means for sequentially transmitting all of the data stored in said data processing terminal system to an external circuit for processing.

9. A system as defined in claim 1 wherein said keyboard includes numerical keys, mathematical algorithm keys, an entry key, a memory recall key, and a clear key.

10. A system as defined in claim 1 further comprising:

a separate printer, and switching means on said keyboard for implementing printout of the displayed information.

11. A system as defined in claim 3 further including data controller circuit means for receiving information from said random access memory means and transmitting it over voice grade telephone lines to a remote central terminal.

12. A system as defined in claim 3 further including data controller means for receiving data from a remote central terminal and storing said data in said random access memory means.

13. A system as defined in claim 12 further including function key means for recalling selected data stored in said random access memory means in accordance with designation data, and displaying the recalled data.
