Abstract
Abstract In a card reader for reading information from a card which may contain the information as optical, magnetic, electronic or physical data, inside a casing is provided a carriage which carries the card and is adapted to be conveyed from an outer position to an inner position by a linear drive mechanism. By not using a pair of drive and pinch rollers as opposed to conventional card readers, the card is free from contaimination by the rollers, and the operation reliability of the card reader is improved. Further, the elimination of rollers also contributes to the reduction in the overall height of the card reader. The clamp mechanism for securing a card to the carriage may be provided with interlocking means which prevents the movement of the carriage until a card is securely gripped by the clamp mechanism.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
A card reader for reading coded information from, and optionally writing coded information into, a card, said card reader comprising: a casing; a carriage received in said casing so as to be moveable between a card inserting position and an information accessing position; electrically actuated clamp means carried by said carriage for securing a card, from which information is to be read, to said carriage; activating means operable upon insertion of a said card into said casing to actuated said clamp means and secure a said card to said carriage; linear conveyer means for selectively moving said carriage between said card inserting position and said information accessing position upon the actuation of said clamp means; and information accessing means disposed adjacent said information accessing position to read information from said card carried by said carriage at said information accessing position.
Claim 2
Dependent Claim
140 words
A card reader for reading coded information from, and optionally writing coded information into, a card, said card reader comprising: a casing; a carriage received in said casing so as to be moveable between a card inserting position and an information accessing position; electrically actuated clamp means carried by said carriage for securing a card, from which information is to be read, to said carriage; activating means operable upon insertion of a said card into said casing to actuated said clamp means and secure a said card to said carriage; linear conveyer means for selectively moving said carriage between said card inserting position and said information accessing position upon the actuation of said clamp means; and information accessing means disposed adjacent said information accessing position to read information from said card carried by said carriage at said information accessing position.
Claim 3
Dependent Claim
32 words
A card reader as defined in claim 1, wherein said linear conveyer means comprises a linear motor consisting of s stator attached to said casing and an armature attached to said carriage.
Claim 4
Dependent Claim
62 words
A card reader as defined in claim 1, wherein said clamp means comprises a fixed clamp member, a moveable clamp member, solenoid means and return spring means, said moveable clamp member adapted to be pressed against said fixed clamp member to grip said card therebetween by being selectively attracted toward said solenoid means against the spring force of said return spring means.
Claim 5
Dependent Claim
37 words
A card reader as defined in claim 3, further comprising interlocking means for preventing movement of said carriage from said card inserting position to said information accessing position until said card is fully secured to said carriage.
Claim 6
Dependent Claim
45 words
A card reader as defined in claim 4, wherein said interlocking means comprises engagement means provided in said moveable clamp member for engagement with a fixed part of said casing when said moveable clamp member is not clamping a card against said fixed clamp member.
Claim 7
Dependent Claim
39 words
A card reader as defined in claim 1, wherein said carriage comprises a planar member extending substantially horizontally and in parallel with the direction along which said carriage is conveyed, and said solenoid means depends from said planar member.
Claim 8
Dependent Claim
96 words
A card reader as defined in claim 6, further comprising a contact unit which is pivotally attached to a bottom wall of said casing via a pivot pin extending parallel to said bottom wall, and another solenoid depending from a top wall of said casing, said contact unit comprising contact pieces extending in a first direction from said contact unit away from said pivot pin and an armature piece extending in a second direction, which is opposite to said first direction, from said contact unit away from said pivot pin, for cooperation with said solenoid means.
Claim 9
Dependent Claim
151 words
A card reader for reading coded information from, and optionally writing coded information into, a card, comprising: a casing; a carriage which is received in said casing so as to be moveable between a card inserting position and an inner most position; electrically actuated clamp means carried by said carriage for securing a card, from which information is to be read, to said carriage; switch means operable upon insertion of a said card into said casing to activate said clamp means and secure a said card to said carriage, linear conveyer means for selectively moving said carriage between said card inserting position and said inner most position upon the activation of said clam means; and information accessing means disposed in said casing to read information from said card carried by said carriage while said card is being conveyed by said carriage between said card inserting position and said inner most position.
Claim 10
Dependent Claim
151 words
A card reader for reading coded information from, and optionally writing coded information into, a card, comprising: a casing; a carriage which is received in said casing so as to be moveable between a card inserting position and an inner most position; electrically actuated clamp means carried by said carriage for securing a card, from which information is to be read, to said carriage; switch means operable upon insertion of a said card into said casing to activate said clamp means and secure a said card to said carriage, linear conveyer means for selectively moving said carriage between said card inserting position and said inner most position upon the activation of said clam means; and information accessing means disposed in said casing to read information from said card carried by said carriage while said card is being conveyed by said carriage between said card inserting position and said inner most position.
