Abstract

A scanning arrangement located within a scanning device which is operative for repetitively scanning indicia having parts of different light reflectivity, for example, bar code symbols, and more particularly, pertains to a novel scanning motor of the arrangement for enabling a scan element which is supported by a holder structure mounted on a mylar motor to implement angular oscillatory movements in a linear scan direction between a pair of scan end positions. Hereby, pursuant to the structure of the scanning device, the scanning arrangement is preferably mounted on a single printed circuit board located within a lightweight scanning device of a hand-held housing of gun-shaped configuration which may be readily held and manipulated by a user of the scanning device. The structure of the scanning motor and of the scanning arrangement which are mounted on a printed circuit board is considerably simplified through the construction of the various components being essentially of molded plastic material, and through the utilization of a mylar leaf spring which limits the end scan positions of a scan element or mirror which is oscillated by a read-start device including a permanent magnet mounted on an arm of the holder for the scan mirror.
