Abstract
Abstract A public terminal receptacle for containing, protecting, and allowing a user access to a computer terminal, telecommunications device for the deaf, or another type of terminal which is telephonically linked and physically adjacent to a public telephone through which the terminal may telecommunicate with other electronic devices. The public terminal receptacle includes a housing having an opening and which is adapted to be attached to a public telephone booth, a drawer which is slidably mounted within the housing to move between a closed position where the drawer is within the housing and an open position where at least a forward portion of the drawer extends out through the opening, the terminal, and a motor drive system mounted within the housing and which is drivingly connected to the drawer for opening and closing the drawer in response to specific electrical signals. The drawer is adapted to contain a terminal and has a keyboard opening through which a user can have physical access to the keyboard on the terminal. The public terminal receptacle is armored to protect the terminal from vandalism. Specific electronic signals can be sent from the public telephone to the motor to open the drawer in a variety of ways.
