Abstract
Abstract A facsimile machine including a data processing system for processing data to be transmitted and received data according to a predetermined manner, which system typically comprises a MODEM, a buffer and a CODEC. The facsimile machine includes two or more interface units dedicated for performing a wire communication function for communicating image data in a wire communication mode using a telephone network and a radio communication function for communicating image data in a radio or wireless communication mode using radio waves. The radio/wire switchable facsimile machine includes a switch which switchingly establishes the wire mode or the radio mode. In one embodiment, the switch is manually operated. In a second embodiment the switch automatically establishes either one of the wire and radio modes in accordance with the current status of a predetermined signal, typically an off-hook signal, which indicates whether the handset of a telephone unit is hooked or unhooked or whether the microphone of a radio set is hooked or unhooked.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
164 words
A communication control apparatus comprising: first interface means connectable to a telephone wire communication network; second interface means connectable to a radiotelephone wireless communication network which is different from said first communication network in mode of communication; processing means for processing data to be transmitted or data received in accordance with a predetermined procedure through said first and second interface means; selecting means for selecting one of said first and second interface means to be operatively connected to said processing means; and controlling means for controlling the overall operation of said apparatus, said controlling means supplying a selection signal to said selecting means thereby causing said selecting means to select one of said first and second interface means to be connected to said processing means; wherein said processing means comprises, a MODEM for modulating data to be transmitted through a selected one of said first and second interface means and demodulating data received through a selected one of said first and second interface means.
Claim 2
Dependent Claim
164 words
A communication control apparatus comprising: first interface means connectable to a telephone wire communication network; second interface means connectable to a radiotelephone wireless communication network which is different from said first communication network in mode of communication; processing means for processing data to be transmitted or data received in accordance with a predetermined procedure through said first and second interface means; selecting means for selecting one of said first and second interface means to be operatively connected to said processing means; and controlling means for controlling the overall operation of said apparatus, said controlling means supplying a selection signal to said selecting means thereby causing said selecting means to select one of said first and second interface means to be connected to said processing means; wherein said processing means comprises, a MODEM for modulating data to be transmitted through a selected one of said first and second interface means and demodulating data received through a selected one of said first and second interface means.
Claim 3
Dependent Claim
32 words
Apparatus of claim 1, wherein said controlling means comprises: an operating unit which is operated by an operator to provide an instruction for selecting one of said first and second interface means.
Claim 4
Dependent Claim
24 words
Apparatus of claim 1, wherein said processing means further comprises: a CODEC for encoding or decoding said data in accordance with a predetermined manner.
Claim 5
Dependent Claim
26 words
Apparatus of claim 3, wherein said processing means further comprises: optical reading means for optically reading an original document to obtain image data to be transmitted.
Claim 6
Dependent Claim
21 words
Apparatus of claim 4, wherein said processing means further comprises: recording means for recording said received data on a recording medium.
Claim 7
Dependent Claim
130 words
A facsimile machine comprising: communication control means for controlling a communication of image data in accordance with a predetermined communication procedure; first connection control means for controlling a connection to a wire transmission line; second connection control means for controlling a connection to a radio set; switching means for switching a connection of said communication control means between said first connection control means and said second connection control means; and system control means for controlling the overall operation of said facsimile machine, said system control means being operatively coupled to said first and second connection control means and to said switching means and controlling a connection status of said switching means automatically in accordance with an off-hook signal supplied from either one of said first and second connection control means.
Claim 8
Dependent Claim
130 words
A facsimile machine comprising: communication control means for controlling a communication of image data in accordance with a predetermined communication procedure; first connection control means for controlling a connection to a wire transmission line; second connection control means for controlling a connection to a radio set; switching means for switching a connection of said communication control means between said first connection control means and said second connection control means; and system control means for controlling the overall operation of said facsimile machine, said system control means being operatively coupled to said first and second connection control means and to said switching means and controlling a connection status of said switching means automatically in accordance with an off-hook signal supplied from either one of said first and second connection control means.
Claim 9
Dependent Claim
95 words
The facsimile machine of claim 6, wherein said off-hook signal is supplied from said first connection control means which is connected to a telephone unit, wherein said off-hook signal has a first state when a handset of said telephone unit is in a hooked state and a second state, which is different from said first state, when said handset is in an unhooked state, said system control means causing said switching means to establish a connection between said communication control means and said first connection control means when said off-hook signal has said second state.
Claim 10
Dependent Claim
27 words
The facsimile machine of claim 6, wherein said first connection control means includes a net control unit which supplies said off-hook signal to said system control means.
Claim 11
Dependent Claim
94 words
The facsimile machine of claim 6, wherein said off-hook signal is supplied from said connection control means which is connected to said radio set and to a microphone, wherein said off-hook signal has a first state when said microphone is in a hooked state and a second state, which is different from said first state, when said microphone is in an unhooked state, said system control means causing said switching means to establish a connection between said communication control means and said second connection control means when said off-hook signal has said second state.
