Talking copiers and duplicators
First Claim
1. In a reproduction machine for producing impressions of an original, the reproduction machine having a photosensitive member and a plurality of discrete operating components including a fuser, a developer, and a copy paper feeder cooperable with one another and the photosensitive member to electrostatically produce the impressions on the copy paper, the reproduction machine including a paper path sensor, a fuser control sensor and a development control sensor, the improvement comprising,a machine controller including a master controller, a shared communication channel, shared logic receive and transmit circuitry,a speaker and associated amplifier,a speech communication module including a microprocessor, a memory, a continuous variable slope delta demodulator, and a converter and filter interconnecting the communication module to the speaker amplifier, the shared logic receive and transmit circuitry interconnecting the master control and the microprocessor, the speech communication module responding to sensed machine conditions to provide an audio response through the speaker.

Abstract
The present invention is a speech module including a central processing unit, a memory, a continuously variable slope delta demodulator, and related filter, amplifier, and speaker circuits connected to a master controller in a reproduction machine. Upon sensing certain machine conditions, the master controller provides suitable signals to the voice response module. In response, the voice response module locates starting addresses and lengths of words and phrases and reproduces the appropriate response. In one embodiment, the speech module is connected to a shared line communication system.
