Abstract

Abstract A communication system for communicating data such as image data has a transmitter and a receiver connected through a communication line. Each transmitter or receiver has an NCU, a modem, a control unit, a reader, a recorder, and a console unit. A sound output unit for producing a sound representing the state of a received image (the number of errors in the received image data) can be included in the transmitter or the receiver. After an operator at the transmitter sends data, the operator is called and can hear a sound message representing the state of the data received by the receiver.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 96 words
A data receiving apparatus comprising: means for receiving data from a transmitter apparatus; first detection means for detecting an end signal representing the end of the data from the transmitter apparatus; means for transmitting an operator call request signal to the transmitter apparatus in response to detection of the end signal; second detection means for detecting an answer signal transmitted by the transmitter apparatus in response to the operator call request signal; and informing means for informing the transmitter apparatus of a receiving state of the received data in response to detection of the answer signal.
Claim 2
Dependent Claim 96 words
A data receiving apparatus comprising: means for receiving data from a transmitter apparatus; first detection means for detecting an end signal representing the end of the data from the transmitter apparatus; means for transmitting an operator call request signal to the transmitter apparatus in response to detection of the end signal; second detection means for detecting an answer signal transmitted by the transmitter apparatus in response to the operator call request signal; and informing means for informing the transmitter apparatus of a receiving state of the received data in response to detection of the answer signal.
Claim 3
Dependent Claim 22 words
An apparatus according to claim 1, wherein said informing means informs the receiving state of the received data via a sound message.
Claim 4
Dependent Claim 24 words
An apparatus according to claim 1, wherein said informing means informs the receiving state of the received data via a signal indicating the state.
Claim 5
Dependent Claim 16 words
An apparatus according to claim 1, wherein the data from the transmitter apparatus comprises image data.
Claim 6
Dependent Claim 26 words
