Abstract
Abstract A facsimile/copy apparatus and method of operation are provided for transmitting a single page document to a plurality of different locations, for transmitting a plural page document to a single location and or for making photostatic copies. The apparatus includes a switch for selecting either a copy function or a facsimile function and memory to identify a number of readings to be performed with the selected function. Feed rollers feed each sheet into the apparatus, and a reversible transfer roller is provided to move the sheet in either of two opposed directions relative to a reader. Odd number readings are read when the sheet is moving in a first direction, while even number readings are obtained while the sheet is moving in an opposed direction. The number of readings that have been taken are compared to the number of required readings stored in the memory. After completion of the required number of readings, the sheet is ejected from the facsimile/copy apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
A method for operating a facsimile/copy machine, comprising the steps of: a) selecting either of a copy function and a facsimile function for said machine; b) entering data into a register to identify a number of readings to be performed with the selected function; c) setting a counter to zero; d) feeding a sheet of material bearing text through said machine in a first direction; e) adding 1 to said counter; f) reading the text on said sheet; g) comparing said counter number to said number of readings to be performed; and h) feeding said sheet in a reverse direction and repeating steps e-g if said counter number is less than said number of readings to be performed, and ejecting said sheet from said machine if said counter equals said number readings to be performed.
Claim 2
Independent Claim
135 words
A method for operating a facsimile/copy machine, comprising the steps of: a) selecting either of a copy function and a facsimile function for said machine; b) entering data into a register to identify a number of readings to be performed with the selected function; c) setting a counter to zero; d) feeding a sheet of material bearing text through said machine in a first direction; e) adding 1 to said counter; f) reading the text on said sheet; g) comparing said counter number to said number of readings to be performed; and h) feeding said sheet in a reverse direction and repeating steps e-g if said counter number is less than said number of readings to be performed, and ejecting said sheet from said machine if said counter equals said number readings to be performed.
Claim 3
Dependent Claim
36 words
The method of claim 1, wherein the step of entering data into a register to identify a number of readings comprises entering a number of copies to be made when the copy function has been selected.
Claim 4
Dependent Claim
34 words
The method of claim 1, wherein the step of entering data into a register to identify a number of readings comprises entering telephone numbers into said register when the facsimile function has been selected.
Claim 5
Dependent Claim
58 words
The method of claim 1, wherein the steps of feeding said sheet of material comprise feeding said sheet with reversible rollers, such that said sheet is fed in said first direction whenever said counter number is odd, and such that said sheet is fed in a direction opposite to said first direction whenever said counter number is even.
Claim 6
Dependent Claim
47 words
The method of claim 1, wherein the step of reading text on said sheet further comprises sensing whether text to be read is present; reading said text when said text is sensed as being present; and terminating said reading when no text is sensed as being present.
Claim 7
Dependent Claim
176 words
A facsimile/copy machine comprising: a feed tray for receiving at least one sheet of material; a feed roller for feeding the sheet from said feed tray in a forward direction; at least one reversible transfer roller aligned generally parallel to said feed roller for receiving the sheet of material from said feed roller and selectively transferring the sheet either in said forward direction or in a reverse direction; A text guide intermediate said feed roller and said reversible transfer roller for permitting movement of a sheet of material from said feed tray to said reversible transfer roller when said transfer roller moves said sheet in said forward direction, and for diverting said sheet from said feed tray and said feed roller when said reversible transfer roller is rotated for moving said sheet in said reverse direction; at least one sensor disposed in proximity to said transfer roller for sensing when a sheet with text is in a position to be read; and a reader in proximity to said sensor for reading the text on said sheet.
Claim 8
Dependent Claim
176 words
A facsimile/copy machine comprising: a feed tray for receiving at least one sheet of material; a feed roller for feeding the sheet from said feed tray in a forward direction; at least one reversible transfer roller aligned generally parallel to said feed roller for receiving the sheet of material from said feed roller and selectively transferring the sheet either in said forward direction or in a reverse direction; A text guide intermediate said feed roller and said reversible transfer roller for permitting movement of a sheet of material from said feed tray to said reversible transfer roller when said transfer roller moves said sheet in said forward direction, and for diverting said sheet from said feed tray and said feed roller when said reversible transfer roller is rotated for moving said sheet in said reverse direction; at least one sensor disposed in proximity to said transfer roller for sensing when a sheet with text is in a position to be read; and a reader in proximity to said sensor for reading the text on said sheet.
Claim 9
Dependent Claim
18 words
The apparatus of claim 6 comprising first and second sensors disposed on opposite respective sides of said reader
Claim 10
Dependent Claim
97 words
The apparatus of claim 6 further comprising: register means for storing a number of readings to be performed by said apparatus; counting means for counting the number of readings performed; comparator means for comparing the number of readings performed with the number of readings stored in said register means; means for ejecting said sheet from said apparatus when the number of readings performed equals said number in said register means; and means for reversing said transfer rollers for performing another reading if said number of readings performed is less than said number stored in said register means.
