Abstract

A tubular body member 12 is gripped in a handle member, not shown, about a circumferential flange 14. At the bottom of the body member 12 is a threshold cap 16 and there is a header 18 at the top held by screws 20. A frame member 22 protrudes through the header 18 and contains a bore 24 which is threaded at the lower end. A spring 26 urges the frame member downward but permits it to rise under light pressure. An actuate switch, not shown, may be arranged between the frame member 22 and the body member 12 in a conventional manner.

Hand Scanner Optical Assembly

A tubular body member 12 is gripped in a handle member, not shown, about a circumferential flange 14. At the bottom of the body member 12 is a threshold cap 16 and there is a header 18 at the top held by screws 20. A frame member 22 protrudes through the header 18 and contains a bore 24 which is threaded at the lower end. A spring 26 urges the frame member downward but permits it to rise under light pressure. An actuate switch, not shown, may be arranged between the frame member 22 and the body member 12 in a conventional manner.

A pair of socket components 28a and 28b are arranged about the frame member 22 at the lower end and are cooperatively configured to hold a carrier
30. The carrier 30 has a tubular neck portion 32, which is threaded for a light spring 34 that is also threaded in the bore 24. The spring 34 serves to return the ball carrier to the initial position, as shown, but is light enough to permit the ball carrier to rotate about the axis through the neck portion 32, and to tilt about the center of the ball to 30 degrees in any direction.

The carrier 30 is bored for an optical system comprising a light-emitting diode (LED) 36 mounted in a header 38, and a 200 mil square photocell 40 having a
14.5 mil aperture in the center is mounted on another header 44 which has a central aperture 46. Tubular spacers 48 hold the headers in place. Electric leads, not shown, pass up through the tubular neck portion 32, the spring 34, and...
