Abstract

The mechanism and circuitry establishes privacy in a dictating system having a number of remote stations and insures that a guard zone exists between successively dictated messages or letters. Microphones 1 and 2 are at remote stations 3 and 4. Each microphone has control buttons such as a Letter punch-Secretary punch button 5 and a Record-Listen-Review button 6 on microphone 1. Only one of stations 3 or 4 is selectively connected to the central dictating and transcribing station 7 during any recording interval through the selection and control circuits 8. Central station 7 has receptacle 9 into which index slip 10 is placed. Slip 10 has markings at regular intervals which correspond to positions on magnetic belt 11. This is rotated in a direction indicated by arrow 12.

Dictating System with Privacy Feature and Guard Zone

The mechanism and circuitry establishes privacy in a dictating system having a number of remote stations and insures that a guard zone exists between successively dictated messages or letters. Microphones 1 and 2 are at remote stations 3 and 4. Each microphone has control buttons such as a Letter punch-Secretary punch button 5 and a Record-Listen-Review button 6 on microphone 1. Only one of stations 3 or 4 is selectively connected to the central dictating and transcribing station 7 during any recording interval through the selection and control circuits 8. Central station 7 has receptacle 9 into which index slip 10 is placed. Slip 10 has markings at regular intervals which correspond to positions on magnetic belt 11. This is rotated in a direction indicated by arrow 12. As belt 11 rotates, carriage 13 moves in a direction indicated by arrow 14 to record information during dictation or read information during transcription. An end of letter punch assembly 13a moves along with and indicates the position of carriage 13 at all times. Also associated with carriage 13 is a microswitch 13b which is actuated by lever 15 that is pivotally mounted at 16. Lever 15 is selectively actuated under control of memory tube 17 and lever actuating slide 18 that are concentrically mounted for movement along rod 19.

During each recording interval, tube 17 is maintained in a constant position by gripper assembly 20 to indicate the end of the previous dictating interval and the beginning of the current interval. As dictation proceeds, carriage 13, assembly 13a, and microswitch 13b are moved as indicated by arrow 14, but tube 17 remains in its initial position. Microswitch 13b has a normally open pair of contacts 21 and 22. Contact 21 is connected to a sour...
