Abstract

PURPOSE:To form an edge cutter for continuous form paper generating no paper jamming in an edge cutting part by setting the peripheral speed of a circular blade rotated in the feed direction of the continuous form paper so as to make the same faster than the feed speed of a feed means. CONSTITUTION:Continuous form paper P has edge parts (p) having feed holes pa arranged thereto along both left and right side edges thereof and, since the edge parts (p) become unnecessary after printing, the edge parts (p) are cut after the completion of printing. Since the edge parts (p) are provided to both side edges of the continuous form paper P, a pair of attaching plates 1 are erected from the attaching plates of a printer toward the positions opposed to both edge parts (p) of the continuous form paper P. Slitters A each constituted by parallelly arranging a pair of a fixed blade and a circular blade 3 so as to come into contact with the continuous form paper P in the lateral direction thereof are arranged inside a pair of the attaching plates 1. Since the peripheral speed of the circular blade 3 due to a rotary drive means B is set so as to be higher than the feed speed of the continuous form paper P due to a feed means C, the shearing of the edge parts (p) becomes faster than the feed of the continuous form paper P and the paper jamming in the edge cutting parts of the slitters A can be avoided.

As shown in FIG. 1, the continuous paper P is a fan-fold type continuous paper, and the feed holes pa are provided along both left and right edges.
Have ears p aligned with each other. After printing, the ears p
Becomes unnecessary. Then, after the printing is completed, the ear portion p is cut off. Since the ears p are provided on both side edges of the continuous paper P, a pair of the mounting plates 1 is provided from a mounting frame (not shown) of the printer toward a position facing both ears p of the continuous paper P. It is standing. Inside each of the pair of mounting plates 1, there is provided a slitter A in which a pair of fixed blades 2 and round blades 3 are juxtaposed so as to contact each other in the width direction of the continuous paper. The line of contact between the fixed blade 2 and the round blade 3 is set so as to coincide with the cutting line of both ears p. Slitter A

As the conveying means C for the continuous paper P, paper feed rollers 7 and 8 are provided which make elastic contact with the upper and lower surfaces of the continuous paper P. The paper feed rollers 7 and 8 are fixed to the shafts 9 and 10,
The shafts 9 and 10 are rotatably pierced through the mounting plate 1.
In this example, as a means for rotating one paper feed roller 7 in contact with the upper surface of the continuous paper P, a rotation driving means B for the round blade 3 is used.
The configuration interlocked with is shown. That is, since the transmission gear 11 is fixed to the end of the shaft 9 projecting outward from the mounting plate 1 and the rotation of the drive gear 6 is transmitted through the idler 12, the paper feed roller 7 is rounded. It is rotationally driven in the same direction as the blade 3. The shaft 13 is a shaft that rotatably supports the idler 12, and is supported by the mounting plate 1. The rotation of the other paper feed roller 8 in contact with the lower surface of the continuous paper P is elastically contacted with the paper feed roller 7 via the continuous paper P, whereby rotation in a relatively opposite direction is transmitted.

The peripheral speed of the round blade 3 by the rotation driving means B is set to be higher than the conveying speed of the continuous paper P by the conveying means C. In this example, the conveying means C is driven in conjunction with the rotation driving means B, so that the gears 6, 12, 11 are
The number of teeth is the same, and the diameter of the round blade 3 is larger than the diameter of the paper feed roller 7. That is, the shearing speed of the ears p (the peripheral speed Vs of the round blade 3) will be described.
And the radius of the paper feed roller 7 is r, the peripheral speed Vs of the round blade 3: the transport speed of the continuous paper P vs = 2πR: 2πr =
R: r. Since R> r, Vs> vs, and the shearing of the ears p becomes faster than the conveyance of the continuous paper P,
It is possible to avoid paper jams and indentations at the edge cutting portion of the slitter A.

When cutting the edge portion p of the printed continuous paper P, the power of the motor 5 is turned on with the continuous paper P being held by the rollers 7 and 8, and the conveying means C moves from right to left. The continuous paper P is conveyed toward. That is, when the power is turned on, the motor 5 is started, the rotary shaft 4 rotates, and the round blade 3 rotates clockwise, so that the continuous paper P passes between the fixed blade 2 and the round blade 3. The ear p is cut off. As described above, since the shearing speed of the ears p is higher than the conveying speed of the continuous paper P, the cut ears p are guided by the curved shape of the round blade 3 and smoothly discharged downward. The continuous paper P whose edge portion p has been cut passes between the paper feed rollers 7 and 8 and is smoothly discharged. Therefore, it is possible to prevent the continuous paper from jamming at the edge-cutting portion of the slitter A without being edge-cut.

It is not necessary to provide the paper feed rollers 7 and 8 as the conveying means for the continuous paper P, and the platen in the printing means (not shown) upstream of the slitter and the tractor for conveying the continuous paper to the printing position. It may be a conveyance unit that performs a series of operations for discharging continuous paper after passing through the printing position, passing through the edge cutting position, and discharging. Further, the conveying means C may be separately driven without being linked to the rotation driving means B.
