Abstract
Abstract In an IC card connector device capable of holding a push rod 4 at a push position while an IC card 1 is connected, a heart-shaped cam groove 10 capable of holding the push rod 4 at two positions or a push position and a projecting position in association with a first transmission pin 15 and a circulating type cam groove 11 and an escape groove 12 which are selectively traced by a second transmission pin 16 in accordance with a projecting amount of the push rod 4 are formed on the outside surface of a frame 3 having a guide groove 3a which is formed on the inside surface thereof and into and from which the IC card 1 is inserted and withdrawn and the receiving portion 13b of a drive plate 13 which associates with an eject arm 5 is permitted to enter into and exit from the circulating type cam groove 11. With this arrangement, the discharge operation and the cancel operation of the IC card 1 can be selectively done in accordance with a projecting amount of the push rod 4 and the size of the eject mechanism 5 can be reduced.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
An IC card connector device comprising a frame for supporting an IC card so that it can be inserted and withdrawn, a push rod capable of reciprocating between a push position and first and second projecting positions and first and second transmission pins turnably attached to the push rod, wherein when the IC card is inserted, the push rod is located at the push position by the first transmission pin, the first transmission pin is released by a first push motion of the push rod in this state to thereby move the push rod to the first projecting position and the IC card is discharged by the second transmission pin in accordance with a second push motion of the push rod, wherein the push rod is permitted to move to the second projecting position which is further projecting from the first projecting position, when the push rod is located at the first projecting position, the push rod is moved to the second projecting position by a pull motion thereof and when the push rod is pushed at the second projecting position, the second transmission pin is turned to thereby cancel the discharge of the IC card.
Claim 2
Dependent Claim
196 words
An IC card connector device comprising a frame for supporting an IC card so that it can be inserted and withdrawn, a push rod capable of reciprocating between a push position and first and second projecting positions and first and second transmission pins turnably attached to the push rod, wherein when the IC card is inserted, the push rod is located at the push position by the first transmission pin, the first transmission pin is released by a first push motion of the push rod in this state to thereby move the push rod to the first projecting position and the IC card is discharged by the second transmission pin in accordance with a second push motion of the push rod, wherein the push rod is permitted to move to the second projecting position which is further projecting from the first projecting position, when the push rod is located at the first projecting position, the push rod is moved to the second projecting position by a pull motion thereof and when the push rod is pushed at the second projecting position, the second transmission pin is turned to thereby cancel the discharge of the IC card.
Claim 3
Dependent Claim
52 words
The IC card connector device according to claim 1, further comprising a drive plate capable of performing a reciprocating motion, wherein said drive plate presses the push rod located at the first projecting position, the second transmission pin moves said drive plate and the IC card is discharged through said drive plate.
Claim 4
Dependent Claim
134 words
The IC card connector device according to claim 2, wherein when the push rod is located at the first projecting position, the second transmission pin confronts said drive plate and when the push rod is moved to the second push position by a push motion in the state that the push rod is located at the first projecting position, the second transmission pin moves said drive plate to thereby discharge the IC card, whereas when the push rod is pushed after it is moved from the first projecting position to the second projecting position, the confrontation between the second transmission pin and said drive plate is cancelled to thereby eliminate the movement of said drive plate caused by the movement of the second transmission pin to thereby cancel the discharge of the IC card.
Claim 5
Dependent Claim
69 words
The IC card connector device according to claim 3, comprising a circulating cam groove and an escape groove, wherein the second transmission pin traces said circulating cam groove and said escape groove in one direction and when the push rod is pushed at the second projecting position, the second transmission pin traces said escape groove to thereby cancel the confrontation of the second transmission pin and said drive plate.
Claim 6
Dependent Claim
45 words
The IC card connector device according to claim 4, wherein when the IC card is discharged, the track of the second transmission pin engaged with said circulating cam groove is displaced to thereby cancel the confrontation of the second transmission pin and said drive plate.
Claim 7
Dependent Claim
27 words
The IC card connector device according to claim 4, comprising a heart-shaped cam groove, wherein the first transmission pin traces said heart-shaped cam groove in one direction.
Claim 8
Dependent Claim
27 words
The IC card connector device according to claim 5, comprising a heart-shaped cam groove, wherein the first transmission pin traces said heart-shaped cam groove in one direction.
Claim 9
Dependent Claim
60 words
The IC card connector device according to claim 7, wherein after the second transmission pin engaged with said circulating cam groove discharges the IC card and falls to a next lower cam surface of said circulating cam groove, the first transmission pin engaged with said heart-shaped cam groove falls to a next lower cam surface of said heart-shaped cam groove.
Claim 10
Dependent Claim
167 words
The IC card connector device according to claim 7, wherein each of the first and second transmission pins is formed to a U-shape having an upper side portion and bent portions formed to both the ends of the upper side portion, first and second projections are formed to the push rod, the upper side portion of the first transmission pin is abutted against the first projection and the upper side portion of the second transmission pin is abutted against the second projection as well as one end of one of the bent portions of the first transmission pin is engaged with said heart-shaped cam groove and one end of one of the bent portions of the second transmission pin is engaged with said circulating cam groove and said escape groove and the first and second transmission pins are elastically pressed between the bent portion of the first transmission pin and the first projection and between the bent portion of the second transmission pin and the second projection.
Claim 11
Dependent Claim
34 words
The IC card connector device according to claim 9, wherein the bent portions formed to both the ends of each of the first and second U-shaped transmission pins are formed to the same length.
