Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
171 words
An electronic card receiving device including a card holder forming a card receiving space in the device for receiving an electronic card, a card latching mechanism for holding the electronic card in position in the card receiving space formed by the card holder, a contacting mechanism for electrically connecting the device to contacts of the electronic card held in position, and a card pushing mechanism for disconnecting the device from the electronic card and pushing it out of the device, wherein said card pushing mechanism comprises a first ejecting plate and a second ejecting plate slidable in directions of inserting and removing the electronic card, said first ejecting plate comprising an abutting portion for applying a force to an inserted electronic card to push it in the direction of removing the card, and said second ejecting plate comprising a stopper guide for obtaining an initial stable condition of the second ejecting plate, a latched condition of the inserted card and a transitional condition of the second ejecting plate during its sliding.
Claim 2
Dependent Claim
171 words
An electronic card receiving device including a card holder forming a card receiving space in the device for receiving an electronic card, a card latching mechanism for holding the electronic card in position in the card receiving space formed by the card holder, a contacting mechanism for electrically connecting the device to contacts of the electronic card held in position, and a card pushing mechanism for disconnecting the device from the electronic card and pushing it out of the device, wherein said card pushing mechanism comprises a first ejecting plate and a second ejecting plate slidable in directions of inserting and removing the electronic card, said first ejecting plate comprising an abutting portion for applying a force to an inserted electronic card to push it in the direction of removing the card, and said second ejecting plate comprising a stopper guide for obtaining an initial stable condition of the second ejecting plate, a latched condition of the inserted card and a transitional condition of the second ejecting plate during its sliding.
Claim 3
Dependent Claim
72 words
An electronic card receiving device as set forth in claim l, wherein said card latching mechanism comprises a card latch including a latch portion having a surface extending substantially perpendicularly to the direction of inserting the electronic card for latching the inserted card, a latch head for selectively permitting the latch portion to latch the card and prohibiting the latching, and an ejecting head for releasing the card from the latched condition.
Claim 4
Dependent Claim
28 words
An electronic card receiving device as set forth in claim 2, wherein said card latch comprises a latch retainer acting upon said latch head to prohibit the latching.
Claim 5
Dependent Claim
50 words
An electronic card receiving device as set forth in claim 2, wherein said card latch comprises a pressing lever to which is connected one end of a coil spring, the other end of which is connected to the first ejecting plate for bringing said latch portion into a latching condition.
Claim 6
Dependent Claim
51 words
An electronic card receiving device as set forth in claim l, wherein said device further comprises a stopper being guided by said stopper guide of said second ejecting plate, and a stopper driving element for transmitting a force to said stopper for releasing said latched condition and obtaining said transitional condition.
Claim 7
Dependent Claim
51 words
An electronic card receiving device as set forth in claim 4, wherein said coil spring is so connected to said pressing lever and said first ejecting plate that the coil spring is not subjected to a force immediately when the first ejecting plate is moved when the electronic card is inserted.
Claim 8
Dependent Claim
25 words
An electronic card receiving device as set forth in claim 2, wherein said card latch is pivotably movable through a slight angle about a bearing.
Claim 9
Dependent Claim
59 words
An electronic card receiving device as set forth in claim 4, wherein said pressing lever is pivotable about a pressing lever shaft at substantially mid portion of the pressing lever and has one end to which is connected one end of said coil spring and the other end of the pressing lever being in contact with said card latch.
Claim 10
Dependent Claim
70 words
An electronic card receiving device as set forth in claim 5, wherein said stopper guide comprises an inlet portion receiving said stopper for said stable condition and said latched condition, and a guide portion having a predetermined length extending from said inlet portion with a step portion in an opposite direction to the inserting direction of the card, said guide portion being relatively slidable to said stopper without substantial resistance.
Claim 11
Dependent Claim
69 words
l0. An electronic card receiving device as set forth in claim 5, wherein said stopper is an L-shaped member and rotatable about an axis in the proximity of a bending portion of the L-shaped member, and one end of the L-shaped member being guided by said stopper guide and the other end being driven by driving means included in said card pushing mechanism to rotate through a predetermined angle.
Claim 12
Dependent Claim
92 words
An electronic card receiving device as set forth in claim 5, wherein said stopper driving element is rotatably connected to one end of the stopper and formed in the stopper driving element with a V-shaped driving pin guide aperture in which a stopper driving pin driven by driving means is movable in response to an operating condition, and said stopper driving pin does not apply any force to said stopper when said stable condition changes to the latched condition, and exerts a force to said stopper when said latched condition is released.
