Optical code reader with hand mounted imager
First Claim
Patent Images
1. A compact imager for electro-optically imaging a target, comprising:
- a) an objective lens for directing light from the target along an optical axis;
b) a printed circuit board carrying electrical circuitry and lying in a plane generally parallel to the optical axis;
c) a solid state, two-dimensional image sensor electrically connected to the circuitry and mounted on the board in a plane generally parallel to the optical axis and the plane of the board;
d) a reflective element overlying the image sensor and inclined relative to the optical axis, and operative for reflecting the light directed by the lens toward the board and to the image sensor for enabling the image sensor to image the target, said reflective element and said lens having respective heights equal to each other as measured in a direction perpendicular to the board;
e) a housing in which the lens, the image sensor and the reflective element are contained; and
f) means for mounting the housing on a finger of a user.

Abstract
An optical imager includes an image sensor, an objective lens having an optical axis for directing an image of a target onto the image sensor, at least one circuit board carrying circuitry connected to the image sensor for providing electronic signals corresponding to information for a target image, a reflective element incident to the optical axis for reflecting the target image onto the image sensor, and wherein the image sensor is arranged such that it is not incident to the optical axis. The imager is sufficiently compact such that it can be worn on a finger of a user.
