Abstract

A portable handheld terminal (20) including optical bar code reader apparatus. A housing (22) having first and second spaced apart, opposing major surfaces (24,26) extending longitudinally between first and second end portions (28,30). A handle portion (40) being interconnected to the housing (22) and extending longitudinally along the second surface (26) so as to provide a handle for holding the bar code reader apparatus. Additionally, the portable handheld terminal (20) includes an optical bar code reader apparatus utilizing a binary imaging sensor (52) and an RF transceiver (79).

Claims

1. A portable handheld terminal, comprising:

(a) a housing;

(b) keyboard means disposed on the housing for entry of data;

(c) display means disposed on the housing for display of data;

(d) optical sensor means disposed in the housing for sensing bar code indicia on an object;

(e) electromagnetic transceiver means contained in the housing for transmitting and receiving electromagnetic signals representing the exchange of data between the portable handheld terminal and a remote location while the portable handheld terminal is in use, said electromagnetic transceiver means including means for initiating transmissions to the remote location;

(f) control means contained in the housing operatively interconnected to the keyboard means, display means, optical sensor means, and electromagnetic transceiver means for controlling operation of the portable handheld terminal; and

(g) power supply means for powering the portable handheld terminal.

2. An apparatus in accordance with claim 1, further including elongated handle means interconnected to the housing for holding the housing, the elongated handle means extending generally along a surface of the housing opposite that of the keyboard means and display means, the elongated handle means being displaced from the surface of the housing along a portion of its length whereby the elongated handle means can be grabbed by a user'"'"'s fingers extending through an opening formed between the elongated handle means and the housing.

3. An apparatus in accordance with claim 2, wherein the elongated handle means is interconnected to a first end portion of the housing and extends back longitudinally toward a second end portion of the housing.

4. An apparatus in accordance with claim 3, wherein the elongated handle means includes a first arcuate portion interconnected to the housing and a second substantially linear portion spaced apart from the surface of the housing.

5. An apparatus in accordance with claim 4, wherein the elongated handle means is formed of one piece with the surface of the housing.

6. An apparatus in accordance with claim 1, wherein the optical sensor means includes binary imaging means including a plurality of imaging elements arranged in an X-Y configuration for sensing the bar code in both the X and directions, whereby the optical sensor means is self-scanning.
