Interface circuit for utilizing a facsimile machine to a PC as a scanner or printer
First Claim
1. A Method of using a facsimile machine to facilitate a transfer for digital image scan data or digital image print data between the facsimile machine and the computer, the method comprising:
- establishing a communication path between the facsimile machine and the computer using a bi-directional passive link; and
activating the transfer in a first mode to send the digital image scan data from the facsimile machine directly to the computer, or activating the transfer in a second mode to receive digital image print data directly from the computer, the digital image scan data and the digital image print data being communicated over the bidirectional passive link, and the activation being initiated using communications software on the computer; and
in the first mode, storing the digital scan data in a computer readable medium, for use as needed, and in the second mode, printing the digital image print data using a facsimile machine printer device.

Abstract
Apparatus for interfacing a conventional facsimile machine with a PC enabling the use of the facsimile machine as a scanner or printer. A first switch assembly selectively couples the PC modem and facsimile machine either to independent telephone lines in a normal mode or to one another in a scan print mode. A manually operated switch assembly is depressed for a brief interval sufficient to activate a ringing circuit which converts DC power from a small battery source to a 20 Hz sine wave of 90 volt amplitude and applies the sine wave signal to the PC to cause the PC or facsimile to enter into a scan or print mode, respectively. The manually operable switch is then released to apply a constant current to the facsimile machine to simulate an off-hook condition. A facsimile machine start button is then operated to start the facsimile machine which scans documents provided therein and transmits the scanned data in a conventional facsimile transmission format or activate the PC to transmit a fax in conventional facsimile transmission format to utilize the facsimile machine as a printer. The PC may be equipped with a suitable software program for converting non-graphic, i.e. such as word-type information into a binary format suitable for use in word processing applications and may store the data in a memory for subsequent use. An automatic circuit may be provided to initiate a scanning or printing mode responsive to receipt of a unique number received from either the facsimile machine or the PC, thus eliminating the need for switches.

7. A method of using a facsimile machine comprising:
-
inputting a document image; activating the optical scanner operatively connected to said document image input of said facsimile machine configured to generate digital image data as the document image is scanned; activating a printer operatively connected to print a document in response to receiving digital image data; and activating a switch providing a connection to a port enabling the direct transfer of digital image scan or print data via a passive link bi-directional direct connection between the facsimile machine and the computer; whereby, said computer being equipped with send receive driver communications software enables the transfer of digital image data between the facsimile machine and the computer through the bi-directional direct connection via the passive link.

8. A method of using a fax machine to transfer digital image data signals via a bi-directional passive link with a computer, for scanning or printing:
-
enabling said scan or print digital image data to transfer between said facsimile machine and computer via a passive link bi-directional direct connection; said computer being equipped with send or receive communications software, such that when activated; scanned document digital image data from the facsimile machine transfers directly to the computer, where it may be stored for use as needed; or digital image data sent from the computer to the facsimile machine, may be printed out, or stored for use as needed.
