Abstract
Abstract Combined radio and tape player apparatus in which the tape cartridge is inserted through a movable door pivotally mounted in the housing of said radio for the tape playing mode of operation. A plurality of touch control switches are arranged on the door for controlling operation of the radio during the radio playing mode of operation. Movement of the door into an open position is resisted by a latching force which is sufficient to resist opening of the door during the operation of the touch control switches but is insufficient to overcome a greater force acting on the door upon insertion of the tape during the tape playing mode of operation.
