Abstract

Abstract An automatic continuous medium setting device includes a delivery means for feeding a continuous medium along a delivery passage, a medium treating means arranged on the delivery passage, a medium accumulating means arranged at the terminal end portion of the delivery passage and a setting means for temporarily setting the continuous medium in a temporary setting position in relation to the medium treating zone, arranged before the medium treating zone on the delivery passage. A medium feed quantity determining means determines the feed quantity of the continuous medium during the delivery when the continuous medium is fed from the temporary position to the accumulating zone. The medium feed quantity determining means being connected to said delivery means.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 146 words
An automatic continuous medium setting device having a delivery passage with a terminal end, comprising: delivery means for feeding a continuous medium along the delivery passage, the continuous medium having a top end; a medium treating zone arranged along the delivery passage; a medium accumulating zone arranged at the terminal end of the delivery passage; an initial setting zone, for placing the continuous medium in a temporary setting position, disposed before the medium treating zone on the delivery passage; and medium feed quantity determining means for determining the feed quantity of the continuous medium during the delivery when the continuous medium is set at a predetermined position in relation to the medium treating zone and the top end of the continuous medium is then fed from said temporary setting position to the accumulating zone, said medium feed quantity determining means being connected to said delivery means.
Claim 2
Dependent Claim 146 words
An automatic continuous medium setting device having a delivery passage with a terminal end, comprising: delivery means for feeding a continuous medium along the delivery passage, the continuous medium having a top end; a medium treating zone arranged along the delivery passage; a medium accumulating zone arranged at the terminal end of the delivery passage; an initial setting zone, for placing the continuous medium in a temporary setting position, disposed before the medium treating zone on the delivery passage; and medium feed quantity determining means for determining the feed quantity of the continuous medium during the delivery when the continuous medium is set at a predetermined position in relation to the medium treating zone and the top end of the continuous medium is then fed from said temporary setting position to the accumulating zone, said medium feed quantity determining means being connected to said delivery means.
Claim 3
Dependent Claim 132 words
An automatic continuous medium setting device according to claim 1, wherein: the continuous medium is folded paper having a top end and is stored, in a folded state in the accumulating zone; the medium treating zone is a printing zone for printing on the folded paper at a printing position; and a paper feed quantity M, determined by said medium feed quantity determining means, is expressed by the following formula: M=N×L1+L2 where N is a positive integer satisfying the requirement of N≧L0/L1, where L1 stands for the fold length of the paper, where L2 stands for the distance between the position of the top end of the paper in the initial setting zone and the printing position and where L0 stands for the distance between the printing position and the accumulating zone.
Claim 4
Dependent Claim 27 words
An automatic continuous medium setting device according to claim 2, wherein the initial setting zone is provided with an electrostatic attracting means for temporarily fixing the paper.
Claim 5
Dependent Claim 59 words
An automatic continuous medium setting device according to claim 2, wherein the paper has guide holes formed therein, said device further comprising: fixing means for temporarily fixing the paper in the initial setting zone, said fixing means having projections which are fitted in said guide holes said projections being able to rise above and sink below the delivery passage.
Claim 6
Dependent Claim 140 words
An automatic setting device for setting the position of a continuous medium, having a delivery passage with a first and a terminal end, comprising: delivery means for feeding the continuous medium along the delivery passage; treating means, positioned adjacent the delivery passage, for treating the continuous medium; accumulating means, positioned at the terminal end of the delivery passage, for accumulating the continuous medium; setting means disposed along the delivery passage at the first end of the delivery passage, for placing the continuous medium in a temporary setting position with respect to said delivery means; and feed quantity determining means, operatively connected to said delivery means, for determining the feed quantity of the continuous medium during the feeding when the continuous medium is set at the temporary setting position and then fed from the temporary setting position to said accumulating means.
Claim 7
Dependent Claim 140 words
An automatic setting device for setting the position of a continuous medium, having a delivery passage with a first and a terminal end, comprising: delivery means for feeding the continuous medium along the delivery passage; treating means, positioned adjacent the delivery passage, for treating the continuous medium; accumulating means, positioned at the terminal end of the delivery passage, for accumulating the continuous medium; setting means disposed along the delivery passage at the first end of the delivery passage, for placing the continuous medium in a temporary setting position with respect to said delivery means; and feed quantity determining means, operatively connected to said delivery means, for determining the feed quantity of the continuous medium during the feeding when the continuous medium is set at the temporary setting position and then fed from the temporary setting position to said accumulating means.
Claim 8
Dependent Claim 127 words
An automatic setting device according to claim 5, wherein: the continuous medium is folded paper having a top end which is stored in said accumulating means in a folded state; said treating means comprises printing means for printing on the folded paper at a printing position; and a paper feed quantity M is determined by said feed quantity determining means and is expressed by the following relation: M=N×L1+L2 where N is a positive integer satisfying the requirement that N≧L0/L1, where L1 is a fold length of the paper, where L2 is a distance between the top end of the paper and said printing position when the paper is in the temporary setting position, and where L0 is a distance between the printing position and the accumulating zone.
