Abstract
Abstract Disclosed is an improvement in a card ejection device having an ejection lever slidably attached to one side of an associated card casing so that the inserting of a card in the card casing may drive the ejection lever out of the front side of the card casing, and so that the pushing of the ejection lever toward the rear side of the card casing may eject the card out of the front side of the card casing. The head section of the ejection lever has two opposite walls that are "U" shaped, rotatably sandwiching an ejection button. The pivot axle of the ejection button passes through the engagement holes made in the confronting walls, thereby permitting the ejection button to turn from the operative position in which the ejection button is put in alignment with the ejection lever to the rest position in which the ejection lever is perpendicular to the ejection lever or vice versa.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
A card ejection device for a card connector comprising an ejection lever slidably attached to one side of an associated casing for a card and having a U-shaped head section with a slot and a cantilever like stopper formed in each of opposing walls and a tail section with a slot, through which one end of a rotary lever in the card connector projects, an ejection button with a through hole, and a pin arranged to pass through the slots of said ejection lever and the through hole of said ejection button, for pivotally connecting said ejection button to the head section of said ejection lever, thereby permitting said ejection button to turn from its operating position, in which said ejection button aligns with said ejection lever, to its rest position, in which said ejection button makes a right angle with said ejection lever and a projection formed in said ejection button abuts to the cantilever like stopper formed in the head section of said ejection lever, or vice versa.
Claim 2
Dependent Claim
170 words
A card ejection device for a card connector comprising an ejection lever slidably attached to one side of an associated casing for a card and having a U-shaped head section with a slot and a cantilever like stopper formed in each of opposing walls and a tail section with a slot, through which one end of a rotary lever in the card connector projects, an ejection button with a through hole, and a pin arranged to pass through the slots of said ejection lever and the through hole of said ejection button, for pivotally connecting said ejection button to the head section of said ejection lever, thereby permitting said ejection button to turn from its operating position, in which said ejection button aligns with said ejection lever, to its rest position, in which said ejection button makes a right angle with said ejection lever and a projection formed in said ejection button abuts to the cantilever like stopper formed in the head section of said ejection lever, or vice versa.
Claim 3
Dependent Claim
47 words
The card ejection device according to claim 1, wherein said ejection button has a semicylindrical projection and said ejection lever has a recess in each of the opposing walls to accommodate the semicylindrical projection of said ejection button, when said ejection button is in the rest potion.
Claim 4
Dependent Claim
98 words
The card ejection device according to claim 1, wherein said ejection lever has a notch in each of the opposing walls and said ejection button has a projection which takes a position opposing to the notices of said ejection lever, when said ejection button is in the operative position, and the notches accommodate the projection, when said ejection button is pushed, prior to actual sliding movement of said ejection lever to be caused by continuous pushing of said ejection button, which causes movement of the rotary lever to ejection the card from the casing of the card connector.
