Abstract
Abstract This invention concerns an optical reader for bar codes characterized in that it comprises, located inside an enclosing housing (1), a linear motor provided with a guide rod (2) on which a moving coil (10) is slidably arranged which carries an objective lens (31) to which at least one illuminator (32) is connected for scanning a bar code provided on a card or the like which can be positioned on a fixed readout plane (35) by means of a guide slot (36) defined on said enclosing housing (1). Said objective lens is operatively connected to a detector (42) carried on a plate (40) which is connected to said moving coil (10).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
An optical reader for bar codes, characterized in that it comprises, within an enclosing housing (1), a linear motor having a guide rod (2) on which a moving coil (10) is mounted slidably, said moving coil (10) supporting an objective (31) whereto at least one illuminator (32) is connected for scanning a bar code provided on a card of the like which may be positioned on a fixed readout surface (35) through a guide slot (36) defined in said enclosing housing (1), a detector (42) being operatively connected to said objective (3 1 ).
Claim 2
Dependent Claim
94 words
An optical reader for bar codes, characterized in that it comprises, within an enclosing housing (1), a linear motor having a guide rod (2) on which a moving coil (10) is mounted slidably, said moving coil (10) supporting an objective (31) whereto at least one illuminator (32) is connected for scanning a bar code provided on a card of the like which may be positioned on a fixed readout surface (35) through a guide slot (36) defined in said enclosing housing (1), a detector (42) being operatively connected to said objective (3 1 ).
Claim 3
Dependent Claim
57 words
An optical reader according to Claim 1, characterized in that it comprises an upper shell half (3) and lower shell half (4) encircling said rod (2) in spaced apart relationship therewith, at the end of said rod (2) there being provided magnets (5) adapted to function as spacers between said rod (2) and said shell halves (3,4).
Claim 4
Dependent Claim
31 words
An optical reader according to the preceding claims, characterized in that it comprises, in contact with said magnets (5), dampers (15) for stopping the translatory movement of said moving coil (10).
Claim 5
Dependent Claim
54 words
An optical reader according to one or more of the preceding claims, characterized in that said objective comprises a lens (31) positioned in a telescope (30) carried on said moving coil (10) and being connected, at the opposed end with respect to said lens (31), to a support plate (40) carrying said detector (42).
Claim 6
Dependent Claim
51 words
An optical reader according to one or more of the preceding claims, characterized in that it comprises a first illuminator (32) and second illuminator (33) of the solid state type and positioned on said telescope (30) at said lens (31) for selectively illuminating the area read by said objective lens (31).
Claim 7
Dependent Claim
64 words
An optical reader according to one or more of the preceding claims, characterized in that it comprises, associated with said support plate (40), a printed circuit (45) including the electric connections for said coil (10), said illuminators (32,33), and said detector (42), for connecting to a connector (50), in turn associated with a flat cable (51) connected to the stationary portions of the apparatus.
Claim 8
Dependent Claim
18 words
An optical reader for bar codes, according to the preeeding claims and substantially as herein described and illustrated.
