Abstract
A card reader locking and unlocking apparatus has a locking lever. One end of the locking lever supports a hook which hooks over a card when the card is locked in position during reading. A key, when brought into abutment with the locking lever, raises the locking lever so that the hook clears the trailing edge of the card and permits the card to be withdrawn. A solenoid acts on the locking lever by a release lever to electrically lock and unlock the card. The release lever is forked so that movement of the locking lever by the key does not cause corresponding movement of the solenoid armature.
Claims3
A device for locking and unlocking a card which is introduced into a card reader, comprising:
- a locking lever;
- a hook mounted to one end of the locking lever and being so positioned that when the card is inserted into the card reader in a read position, the hook hooks over a trailing edge of the card;
- a key mounted such that it may be brought into abutting relationship with the locking lever and, when abutting therewith, causing the locking lever to be sufficiently raised as to unhook the hook from the trailing edge of the card;
- a solenoid;
- and
- a release lever fixed to the solenoid and raising the locking lever upon actuation of the solenoid.
