Abstract
A bar code reader has a permanent magnet, an MR device formed integrally with the permanent magnet and a head frame housing the permanent magnet and MR device. The head frame comprises an open casing having a cut at the front end thereof. An internal lead wire faces the front end of the head frame and is fitted and fixed in the cut of the head frame. A printed circuit board on which the MR device is mounted is fixed in the opening of the head frame and electrically connected to the internal lead wire by means of a projection. An external lead wire is passed through the bottom of the head frame and spot-joined to the internal lead wire. The permanent magnet is supported at the bottom of the head frame and fixed in the head frame. A resin film is so formed as to cover the internal lead wire and fill the cut in the head frame and also to be flush at the surface thereof with the front end of the head frame.
