Abstract
Abstract A readerlwriter for an IC card external memory comprises a carriage longitudinally movable in a casing (10) which is normally held in a waiting position in which the carriage (31) is held by spring means (25) and is moved to an operating position by manually inserting the card (C) engaging therewith against the spring force. A block member (41) having contact pins (42) is snugly embraced by the carriage (31) and is adapted to move vertically relative to the carriage to said operating position by sliding up an inclined floor (15') so as to establish electrical connection with card contact points. The IC card (c) is held by angularly movable hooks (21) actuated by lever means (51) to be moved by said carriage. Said hooks (21) are retracted by disengaging said lever means (51) from latching means (62") and concurrently the carriage is returned to the initial position to eject the card out of the casing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
100 words
Device for reading and/or writing an IC card as external memory which has a plurality of contact points exposed to be flush with the surface of one side thereof, characterized by comprising a casing provided with an inlet slit for inserting said card formed at one end wall of said casing, a block member having a corresponding number of contact pins to be electrically connected with said contact points, and locking means adapted to be actuated when said IC card is fully inserted in said casing so that said electric connection may reliably be kept during said reading and/or writing.
Claim 2
Dependent Claim
100 words
Device for reading and/or writing an IC card as external memory which has a plurality of contact points exposed to be flush with the surface of one side thereof, characterized by comprising a casing provided with an inlet slit for inserting said card formed at one end wall of said casing, a block member having a corresponding number of contact pins to be electrically connected with said contact points, and locking means adapted to be actuated when said IC card is fully inserted in said casing so that said electric connection may reliably be kept during said reading and/or writing.
Claim 3
Dependent Claim
110 words
Device as claimed in Claim 1 characterized in that said locking means is a pair of hooks arranged in the vicinity of said first end wall of the casing ' and adapted to be angularly moved together between a potential position where said hooks are retracted in the casing and a locking position where said hooks are exposed so as to engage with the trailing edge of the card completely inserted in the casing and that said end wall is recessed in the central part so that a trailing end parts of the card is partly exposed between the opposite side portions where said hooks are engaged with said card.
Claim 4
Dependent Claim
60 words
Device as claimed in Claim 1 characterized by further comprising a carriage arranged in said casing so as to be longitudinally movable together with said block member between a waiting position and an operating position where the contact pins of said block member may be electrically connected with the contact points of the IC card fully inserted in the casing.
Claim 5
Dependent Claim
99 words
Device as claimed in Claim 3 characterized in that said carriage is normally held in said waiting position by spring means and movable towards said operating position by manually pushing the IC card engaging therewith against the force of said spring means, said block member being so arranged as to be movable longitudinally together with said carriage and vertically relative thereto, whereby said contact points of the card completely inserted in the casing may be electrically connected with the contact pins of the block member vertically moved up relative to the carriage which is brought at said operating position.
Claim 6
Dependent Claim
75 words
Device as claimed in Claim 4 characterized in that said carriage is provided with a flange at the leading end thereof so as to be engaged with the leading edge of the IC card and so formed as to snugly embrace said block member which is vertically moved up relative to the carriage longitudinally moved by said card to be manually pushed along guide means towards said operating position by sliding on a sloped floor.
Claim 7
Dependent Claim
48 words
Device as claimed in Claim 5 characterized in that said flange has a vertical portion protruded from the upper wall of the carriage and a second portion extended parallel to said wall so as to form a pocket for receiving the leading end portion of the IC card.
Claim 8
Dependent Claim
131 words
Device as claimed in Claim 2 characterized by further comprising lever means which is engaged with said locking hooks and arranged so as to be longitudinally moved between a first position where said lever means is normally held by second spring means and by latching means engaging therewith so as to keep said locking hooks in said retracted position and a second position to where said lever means is forcedly moved against the force of said second spring means by said carriage moving towards said operating position, with momentarily clearing said engagement with said latching means owing to electromagnetic mechanism, so as to actuate said hooks to be in said locking position, said hooks being kept in said locking position owing to engagement of said lever means with said latching means.
Claim 9
Dependent Claim
168 words
Device as claimed in Claim 7 characterized in that said lever means comprises a longitudinally elongated lever engaged with at least one of said locking hooks at one end thereof and formed with slots to respectively engage with headed pins planted on the casing so as to be movable in parallel to the carriage movement direction by a distance defined by the slot length, and a slider lever connected with said elongated lever by third spring means so that said two levers are normally held in said first position together owing to said second and third spring means but when the slider lever is forcedly moved against said second spring means by said carriage moving towards said operating position, the elongated lever is held for a while in the first position owing to the engagement with said latching means and by electromagnetically clearing said engagement with the latching means for a moment said elongated lever is snappingly moved to said second position owing to said third spring means.
Claim 10
Dependent Claim
87 words
Device as claimed in Claim 8 characterized in that said latch means comprises an angularly movable two-arm lever provided with an armature at one end and a solenoid so that when said solenoid is energized for a moment when the IC card is completely inserted in the casing and the reading and/or writing operation has been finished, said latch lever is angularly moved so as to disengage the other end thereof from the elongated lever to be made movable to either of said first and second positions.
Claim 11
Dependent Claim
62 words
Device as claimed in claim 8 characterized in that there are provided further a second latch lever and second solenoid so that said first solenoid is adapted to be energized when the IC card is going to be just completely inserted in the casing and said second solenoid is adapted to be energized after the reading and/or writing operation has been finished.
Claim 12
Dependent Claim
101 words
Device as claimed in Claim 9 characterized in that there is provided a button having a rod fixed thereto of which free end is normally held to be outside of a sensor by spring means so that when said button is manually pushed against the force of said spring said rod free end is detected by said sensor so as to energize said solenoid and make the elongated lever movable to the first position, and when said button is further pushed the rod free end mechanically actuates said latch lever like as the solenoid attracts the armature of said latch lever.
Claim 13
Dependent Claim
121 words
Device as claimed in Claim 10 characterized in that there is provided a button having a rod fixed thereto of which free end is normally held in the vicinity of said second latch lever by spring means so that when said button is manually pushed said rod free end mechanically actuates said second latch lever like as the concerned solenoid attracts the armature thereof, said rod having a branched extension of which free end is positioned just behind the first latch lever so that during reading and/or writing operation the latch lever of which armature is attracted by the energized solenoid is adapted not to allow pushing button by abutment of the free end of said branched extension on said lever.
