Abstract
Abstract An apparatus for controlling the passage of photomaterial through an electronic phototype setter which operates in conjunction with an automatically operated developing apparatus. Switching means are provided and actuated by the photomaterial to cause the setter to stop when the photomaterial accumulates between the outlet of the setter and the inlet of a developing apparatus. A cutting device is provided to cut the photomaterial when the material is stretched between the setter and the developing apparatus.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
75 words
Apparatus for controlling the passage of photomaterial through an electronic phototype setter cooperating with an automatically operating developing apparatus, comprising first switch means actuated by the photomaterial to cause the setter to stop when the photomaterial accumulates between an outlet of the setter and an inlet of the developing apparatus, a cutting device, a second switch means actuated by the photomaterial for operating said cutting device to cut through the photomaterial when it is stretched.
Claim 2
Dependent Claim
75 words
Apparatus for controlling the passage of photomaterial through an electronic phototype setter cooperating with an automatically operating developing apparatus, comprising first switch means actuated by the photomaterial to cause the setter to stop when the photomaterial accumulates between an outlet of the setter and an inlet of the developing apparatus, a cutting device, a second switch means actuated by the photomaterial for operating said cutting device to cut through the photomaterial when it is stretched.
Claim 3
Dependent Claim
114 words
Apparatus for controlling the passage of photomaterial through an electronic phototype setter cooperating with an automatically operating developing apparatus, comprising: first switch means actuated by the photomaterial to cause the setter to stop when the photomaterial accumulates between an outlet of the setter and an inlet of the developing apparatus, a cutting device, second switch means actuated by the photomaterial for operating said cutting device to cut through the photomaterial when it is stretched, and a blocking device, third switch means actuated by the photomaterial for operating said blocking device to prevent the photomaterial from entering the developing apparatus in the case that a previously cut piece of material has not passed completely thereinto.
Claim 4
Dependent Claim
114 words
Apparatus for controlling the passage of photomaterial through an electronic phototype setter cooperating with an automatically operating developing apparatus, comprising: first switch means actuated by the photomaterial to cause the setter to stop when the photomaterial accumulates between an outlet of the setter and an inlet of the developing apparatus, a cutting device, second switch means actuated by the photomaterial for operating said cutting device to cut through the photomaterial when it is stretched, and a blocking device, third switch means actuated by the photomaterial for operating said blocking device to prevent the photomaterial from entering the developing apparatus in the case that a previously cut piece of material has not passed completely thereinto.
Claim 5
Dependent Claim
117 words
Apparatus as claimed in claim 1, and further characterized by said cutting device being arranged between the outlet of the phototype setter and the inlet of the developing apparatus, an elongated guideway for receiving the photomaterial, said first switch means including a contacting device responding when the photomaterial accumulates in said guideway and actuating to stop the production of clock pulses in the photOtype setter and the acceptance of further setting information, said second switch means including a contacting device responsive to the pull of the photomaterial in said guideway and initiating an accelerated feed of the photomaterial by a certain length, and said cutting device being arranged cut the photomaterial after the accelerated feed has terminated.
Claim 6
Dependent Claim
55 words
Apparatus as claimed in claim 3, wherein said first switch means includes a plate resiliently arranged on one side of said guideway pressed sideways by the strip of photomaterial which accumulates in waves in said guideway, said first switch means contact being actuated by said plate when the accumulation pressure has attained a certain value.
Claim 7
Dependent Claim
60 words
Apparatus as claimed in claim 3, wherein said second switch means includes a resilient spring arranged on one side near an inlet opening of the guideway, said spring being curved sideways by the tightening of a strip of photomaterial, said second switch means contact being actuated by said spring when the tension of the strip has attained a certain value.
Claim 8
Dependent Claim
105 words
Apparatus as claimed in claim 1, and further characterized by: a contactor arranged at the inlet of the developing apparatus to establish the existence of photomaterial at a contacting position, a plurality of electromagnetically controlled, resilient locking pins arranged closely in front of the contractor at the end of a guideway leading into the developing apparatus, and a contact actuated by the contractor when photomaterial is present at the contacting position, for moving said resilient locking pins into light contact with the material to prevent entrance of other strips of the photomaterial into the developing apparatus until the first-mentioned photomaterial moves past the contacting position.
Claim 9
Dependent Claim
106 words
Apparatus as claimed in claim 3, and further characterized by: a contractor arranged at the inlet of the developing apparatus to establish the existence of photomaterial at a contacting position, a plurality of electromagnetically controlled, resilient locking pins arranged closely in front of the contractor at the end of a guideway leading into the developing apparatus and a contact actuated by the contactor when photomaterial is present at the contacting position, for moving said resilient locking pins into light contact with the material to prevent entrance of other strips of the photomaterial into the developing apparatus until the first mentioned photomaterial moves past the contacting position.
Claim 10
Independent Claim
118 words
An apparatus for controlling the passage of photomaterial through an electronic phototype setter comprising: means for delivering the photomaterial through the phototype setter; means for delivering the photomaterial from the setter to a developing apparatus; means positioned between said setter and said developing apparatus for accumulating the photomaterial; first switch means responsive to the accumulation of the photomaterial between said setter and said developing apparatus to stop further advancement of the photomaterial to said developing apparatus; second switch means responsive to the stretching of the photomaterial between said setter and said developing apparatus; and cutting means actuated by said second switch means to cut the photomaterial when the photomaterial is stretched between said setter and said developing apparatus.
Claim 11
Independent Claim
118 words
An apparatus for controlling the passage of photomaterial through an electronic phototype setter comprising: means for delivering the photomaterial through the phototype setter; means for delivering the photomaterial from the setter to a developing apparatus; means positioned between said setter and said developing apparatus for accumulating the photomaterial; first switch means responsive to the accumulation of the photomaterial between said setter and said developing apparatus to stop further advancement of the photomaterial to said developing apparatus; second switch means responsive to the stretching of the photomaterial between said setter and said developing apparatus; and cutting means actuated by said second switch means to cut the photomaterial when the photomaterial is stretched between said setter and said developing apparatus.
Claim 12
Dependent Claim
46 words
An apparatus for controlling the passage of photomaterial through an electronic phototype setter according to claim 8 further including, means actuated by said second switch means to rapidly advance the photomaterial a predetermined length from said setter toward said developing apparatus before the photomaterial is cut.
