Abstract
Abstract A counter controls the processing of multiple copies of an original in a high-speed, roll fed copying machine. Timer circuitry operated in the multiple copy mode provides signals to initiate the feeding of copy material from the roll for successive copies. A movable length sensor in the path of the copy material discontinues the feeding of copy material and actuates a cutter to sever a preselected length of copy material. The time period between signals is variable in accordance with the selected copy length so as to provide a corresponding spacing between successive lengths of severed copy material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
260 words
In an apparatus for making multiple copies of an original on copy material, comprising copy processing stations including charging, cutting, exposing and developing stations spaced along a copy path, a copy material supply including a roll of copy material, copy material transport means for feeding copy material from said roll into said path at a predetermined rate, said cutting station including cutter means for severing predetermined lengths of copy material from said roll, copy selector means for selecting a predetermined number of copies to be made by said apparatus, control circuit means connected to said copy selector means and said transport means for controlling the feeding of copy material from said supply in accordance with the number of copies selected, said control circuit means including timer means having a predetermined time-out period, said timer means being operable to cause said control circuit means to operate said transport means at the beginning of each time-out period, the number of time-out periods of said timer means being controlled in accordance with the number of copies selected, and sensor means positioned at a critical location along said path for sensing the arrival of said copy material thereat, the operation of said transport means being discontinued and said cutter means actuated to sever a length of copy material from said roll in response to the sensing of said material by said sensor means said copy material arriving at said sensor means a predetermined time prior to the timing out of said timer means, thereby to provide corresponding spacing between successive lengths of copy material.
Claim 2
Dependent Claim
260 words
In an apparatus for making multiple copies of an original on copy material, comprising copy processing stations including charging, cutting, exposing and developing stations spaced along a copy path, a copy material supply including a roll of copy material, copy material transport means for feeding copy material from said roll into said path at a predetermined rate, said cutting station including cutter means for severing predetermined lengths of copy material from said roll, copy selector means for selecting a predetermined number of copies to be made by said apparatus, control circuit means connected to said copy selector means and said transport means for controlling the feeding of copy material from said supply in accordance with the number of copies selected, said control circuit means including timer means having a predetermined time-out period, said timer means being operable to cause said control circuit means to operate said transport means at the beginning of each time-out period, the number of time-out periods of said timer means being controlled in accordance with the number of copies selected, and sensor means positioned at a critical location along said path for sensing the arrival of said copy material thereat, the operation of said transport means being discontinued and said cutter means actuated to sever a length of copy material from said roll in response to the sensing of said material by said sensor means said copy material arriving at said sensor means a predetermined time prior to the timing out of said timer means, thereby to provide corresponding spacing between successive lengths of copy material.
Claim 3
Dependent Claim
59 words
The apparatus of claim 1 further including copy length selector means operable to adjust the positioning of said sensor means along said copy paper path, said copy length selector means being connected to said control circuit means for varying said time-out period of said timer means, whereby said predetermined time period is varied in accordance with copy length selection.
Claim 4
Dependent Claim
55 words
The apparatus of claim 2 wherein said predetermined time period is of a first duration when said selector means is operated to select a copy length less than a predetermined length and is of a second, greater duration when said copy length selector is operated to select a copy length greater than a predetermined length.
Claim 5
Dependent Claim
91 words
The apparatus of claim 3 further including switch means connected electrically to said timer means for varying said time-out period, said switch means having a first position wherein said time-out period is of said first duration and a second position wherein said time-out period is of said second duration, and wherein said length selector means is coupled to said switch means and movable in a first direction to operate said switch means to said first position and movable in a second direction to operate said switch means to said second position.
Claim 6
Dependent Claim
232 words
A copying machine for making multiple copies of an original on copy material comprising copy processing stations including charging, exposing and developing stations spaced along a copy path, a copy material supply, copy material transport means for feeding copy material from said supply into said path at a predetermined rate, copy selector means for selecting a predetermined number of copies to be made by said machine, control circuit means connected to said copy selector means and said transport means for controlling the feeding of copy material from said supply in accordance with the number of copies selEcted, said control circuit means including timer means having a predetermined time-out period, said timer means being operable to cause said control circuit means to operate said transport means at the start of each time-out period and operable to initiate another time-out period at the termination of a previous time-out period, the number of time-out periods of said timer means being controlled in accordance with the number of copies selected, and sensing means positioned at a critical location along said path for sensing the arrival of said copy material thereat, the operation of the transport means being discontinued in response to the sensing of said material by said sensing means, said copy material arriving at said sensing means prior to the timing-out of said timer means, thereby to provide spacing between successive lengths of copy material.
Claim 7
Dependent Claim
232 words
A copying machine for making multiple copies of an original on copy material comprising copy processing stations including charging, exposing and developing stations spaced along a copy path, a copy material supply, copy material transport means for feeding copy material from said supply into said path at a predetermined rate, copy selector means for selecting a predetermined number of copies to be made by said machine, control circuit means connected to said copy selector means and said transport means for controlling the feeding of copy material from said supply in accordance with the number of copies selEcted, said control circuit means including timer means having a predetermined time-out period, said timer means being operable to cause said control circuit means to operate said transport means at the start of each time-out period and operable to initiate another time-out period at the termination of a previous time-out period, the number of time-out periods of said timer means being controlled in accordance with the number of copies selected, and sensing means positioned at a critical location along said path for sensing the arrival of said copy material thereat, the operation of the transport means being discontinued in response to the sensing of said material by said sensing means, said copy material arriving at said sensing means prior to the timing-out of said timer means, thereby to provide spacing between successive lengths of copy material.
