Facsimile paper cutter with first cut means

Claim 2

In a document reproduction system in which a document is scanned from a leading edge to a lagging edge and is reproduced by marking means on a substantially continuous sheet of recording medium, medium-severing apparatus comprising a medium-severing device located a distance from said marking means, means for driving said medium from said marking means to said severing device, a first timer operable responsive to either one of said document edges passing said marking means for actuating said severing means a predetermined time after said edge passing corresponding to the time required for said driving means to drive said medium from said marking means to said severing device and a second timer operable when a document-lagging edge passes said marking means for initiating the operation of said first timer to cause said severing device to sever said medium at an intermediate place between the lagging edge of a last preceding document reproduction and the leading edge of the next document reproduction.

Claim 3

Facsimile recording medium-severing apparatus for use with a facsimile receiver which records a document copy on a substantially continuous sheet of recording medium extending from a supply roll past a marking means and to the severing apparatus, said receiver having medium-driving means for driving said medium when said receiver is receiving signals from a transmitter and for a predetermined period after said signals cause to drive the reproduced document from said marking means to the severing apparatus, said medium-severing apparatus comprising a medium-severing device, means for controlling said severing device to sever said medium at the beginning and end of each document, and means operative responsive to the beginning of receipt of signals from said transmitter to initiate recording of a new document for causing said severing device to sever said medium at an intermediate place along the portion of said medium which passed between said recording means and said severing device during said predetermined period after the last preceding document.

Claim 4

Facsimile recording medium-severing apparatus for use with a facsimile receiver which records a document copy on a substantially continuous sheet of recording medium extending from a supply roll past a marking means and to the severing apparatus, said receiver having medium-driving means for driving said medium when said receiver is receiving signals from a transmitter and for a predetermined period after said signals cause to drive the reproduced document from said marking means to the severing apparatus, said medium-severing apparatus comprising a medium-severing device, means for controlling said severing device to sever said medium at the beginning and end of each document, and means operative responsive to the beginning of receipt of signals from said transmitter to initiate recording of a new document for causing said severing device to sever said medium at an intermediate place along the portion of said medium which passed between said recording means and said severing device during said predetermined period after the last preceding document.

Claim 5

FacsimiLe recording medium-severing apparatus for use with a facsimile receiver having means for recording a document copy from a leading edge to a lagging edge on a substantially continuous sheet of recording medium extending from a supply roll past a marking means to the severing apparatus, said receiver also having medium-driving means for driving said medium and means for actuating said medium-driving means when said receiver is receiving signals from a transmitter and for a predetermined time period after said signals cease to drive the lagging edge of the reproduced document on said medium to the severing apparatus, said medium-severing apparatus comprising a severing device, a memory timer operative to measure a timing event and to actuate said severing device at the end of a timing event, the length of a timing event corresponding to the time required for said medium to pass from said marking means to said severing device, means including said actuating means for preparing said timer to be able to measure a timing event whenever said medium driving means is actuated, means for initiating a timing event at a time corresponding to the presence at the recording means of each leading and lagging edge, and means operable for initiating a timing event during said predetermined time period, said initiated timing event stopping at the end of said predetermined time period and restarting when signals begin for the next subsequent document copy.

Claim 6

FacsimiLe recording medium-severing apparatus for use with a facsimile receiver having means for recording a document copy from a leading edge to a lagging edge on a substantially continuous sheet of recording medium extending from a supply roll past a marking means to the severing apparatus, said receiver also having medium-driving means for driving said medium and means for actuating said medium-driving means when said receiver is receiving signals from a transmitter and for a predetermined time period after said signals cease to drive the lagging edge of the reproduced document on said medium to the severing apparatus, said medium-severing apparatus comprising a severing device, a memory timer operative to measure a timing event and to actuate said severing device at the end of a timing event, the length of a timing event corresponding to the time required for said medium to pass from said marking means to said severing device, means including said actuating means for preparing said timer to be able to measure a timing event whenever said medium driving means is actuated, means for initiating a timing event at a time corresponding to the presence at the recording means of each leading and lagging edge, and means operable for initiating a timing event during said predetermined time period, said initiated timing event stopping at the end of said predetermined time period and restarting when signals begin for the next subsequent document copy.

Claim 7

In the apparatus of claim 3 wherein said preparing means comprises a relay operable responsive to the initiation of transmission signals to actuate said medium-driving means and to prepare said memory timer, said actuating means comprising a second timer operable responsive to the ceasing of transmission signals for measuring said predetermined period and for maintaining said driving means actuated and said timer prepared during said predetermined period, and wherein said timing event initiating means comprises a switch operable by said second timer for initiating said timing event during said predetermined period.
