Abstract

A hand-operated scanner having an inverted T-shaped extension for slideably receiving two adjacent fingers for manipulating the scanner and simultaneously allowing the operator'"'"'s fingers to remain free for merchandise packaging, merchandise check-out and/or making keyboard entries by artful placement of the extension in relation to the scanner reading head.

Claims

1. A hand-operated scanner for scanning a printed data bearing medium by photo-optical means comprising:

housing means provided with a reading aperture end adapted to be placed contiguous with and moved over, the data bearing medium;

illumination means mounted in said housing means to provide for illumination at the reading aperture;

photosensitive means mounted on said housing and adapted to receive through said reading aperture, reflected illumination from the data to be read;

holding means extending from said housing including an inverted T shaped configuration for receiving at least two adjacent fingers of an operator'"'"'s hand for manipulation of the scanner; and

,

guide means attached to said housing means at said reading aperture end and projected outwardly to allow a visual check for manual registration of the reading aperture end with the data to be scanned.

2. In a hand-operated scanner according to claim 1 wherein said T shaped configuration comprises a horizontal member of airfoil configuration having a cross-section which increases in thickness in the direction towards the reading aperture.

3. In a hand-operated scanner according to claim 2 wherein the outer portions of said horizontal member are provided with ridges.

4. In a hand-operated scanner according to claim 3 wherein said vertical member is integrally connected with said housing means over an extended area in the direction toward said reading aperture.

5. In a hand-operated scanner according to claim 4 wherein said housing means includes wing-like extension means containing said illuminating means.

6. In a hand-operated scanner according to claim 4 wherein the shortest distance between a plane at which the reading aperture is positioned and the furthest portion of the horizontal member for receiving two adjacent fingers is between 11/2 to 3 inches.

7. A hand-operated scanner for scanning a printed data-bearing medium by photo-optical means comprising:

housing means provided with a reading aperture end adapted to be placed contiguous with and moved over the data-bearing medium;

illumination means mounted in said housing means in a manner to avoid contact between said hand and heat from said illumination means to provide for illumination at the reading aperture;

photosensitive means mounted on said housing and adapted to receive through said reading aperture, reflected illumination from the data to be read; and

,

holding means, rigidly connected to said housing means and adapted to matingly receive at least two adjacent fingers of said hand, for permitting (1) secure grasping of said holding means and thereby said housing means when scanning said printed data-bearing medium and for permitting (2) continued holding of said housing means when said fingers are extended and freely maneuverable even beyond said reading aperture end when not scanning said printed data-bearing medium.

8. A hand operated scanner according to claim 7 including:

guide means attached to said housing means at said reading aperture end and projected outwardly to allow a visual check for manual registration of the reading aperture end with the data to be scanned.
