US 5,179,505 A · Ejector for memory card

Abstract

A memory card ejector has an eject knob to be externally operated and a lock release button. As a memory card is loaded in a card receiving chamber, a lock lever moves to a locking position so that a claw of the lock lever engages with a recess of the memory card to lock the card at a load completion position. In association with the lock lever, a card detecting switch turns off the supply of power to circuit components of an electronic apparatus. When the lock release button is depressed, the lock lever rotates in the counter-clockwise direction to move to a lock release position whereat the card detecting switch is turned off to stop powering the electronic apparatus. As the eject knob is slid, an associated lever together with an eject lever moves so that the end of the eject lever pushes a slide plate toward a card inlet port with a relatively strong force. A hook of the slide plate pushes the front end of the memory card to discmount it from a connector. As the associated lever further rotates, the eject lever rotates using a stopper as a fulcrum to thereby move the slide plate by a relatively large amount and extend the rear end of the memory card out of the card inlet port.

Dependent claims

An ejector for ejecting a memory card from a card receiving chamber, comprising:

a slide member movable between a retracted position and an eject position, at said retracted position said memory card being connectable to a connector mounted at an innermost position of said card receiving chamber, and at said eject position a rear end of said memory card extending out of said card receiving chamber while a front end of said memory card is pushed by said slide member;
an operation member operated when said memory card is ejected;
an associated member swingable between a first range and a second range, in association with said operation member;
an eject member for moving said slide member from said retracted position to said eject position, said eject member being rotatably mounted on said associated member and moving integrally with said associated member while said associated member swings in said first range, and during the motion of said eject member, one end of said eject member causing said slide member to move from said retracted position to dismount said memory card from said connector;
and
a stop member for receiving the other end of said eject member to rotate said eject member while said associated member rotates in said second range, said slide member being moved to said eject position by rotation of said eject member.
