摘要： A device for automatically answering telephone calls to be used with a magnetic-sheet or belt-type dictating machine having a cylinder for receiving sheet- or belt-type recording media and a sound head carriage which is guided across the cylinder between two limit switches set in the path of motion of the carriage. The device has an automatic return for placing the sound head carriage in a starting position. When a call is received, the device activates the sound head carriage causing it to move across the cylinder thus enabling a recorded message to be transmitted over the telephone line. When the complete message has been transmitted, the carriage automatically is returned and is set in a start position for transmitting the message again if another call is received.

摘要： A record indexing device for a dictating machine having a sound head carriage movable along the length of a cylinder. The indexing device includes a limit switch arranged in the path of motion of said sound head carriage to be actuated by it when it is returned and a return element which acts to put the sound head carriage into its starting position. When the carriage is returned, the return element pushes the sound head carriage in its starting position and the limit switch is deactivated to set the cylinder in its start position. This enables one position, i.e., the starting position, to be determined automatically when using the machine both for recording and reproducing.
