[0027] FIG. 1A is a diagram showing a structural example including a cutting device according to a first embodiment of the present invention.

[0028] The continuous paper cutting apparatus according to the first embodiment of the present invention includes: a position detection gear 101 having two or more slits having different widths in the direction of rotation of the gear 101, and the gear is rotatable to detect paper cutting The position of the machine; the gear 102, to decelerate and transmit the rotation of the position detection gear in the opposite direction of rotation; the paper cutter drive gear 103, to rotate through the gear 102; the paper cutter drive arm 104, one end of which is connected to the A paper cutter driving gear 103, so that the paper cutter driving arm 104 is rotatable, thereby driving the paper cutter; a movable blade 106 is rotatably connected to the paper cutter driving arm 104, and is reciprocally driven by the paper cutter driving arm 104; fixed...

[0083] In the continuous sheet cutting apparatus according to the second embodiment of the present invention, a stepping motor is employed as a cutter motor, specifically, as a drive motor for driving the position detection gear 101 .

[0084] Except for the position detection gear 101, the structure of the second embodiment is the same as that of the first embodiment.

[0085] In the position detection gear 101 of the second embodiment, the number of initial position detection slits (ie, slits 108 ) is at least one. The continuous sheet cutting apparatus according to the second embodiment determines the cutting end position by counting the number of steps for driving the stepping motor.

[0086] Fig. 9 is a flowchart showing cutter position initialization processing performed by the continuous paper cutting apparatus of the second embodiment. In order to control the cutter position and the continuous sheet position, the present invention executes a process of bringing the mo...

Abstract

Slits are provided in a position detection gear for driving a cutter. When the position detection sensor has sensed from the detection of the slits of the position detection gear that the cutter is in a cutting termination position, a control unit operates a conveyance mechanism in the direction in which the continuous paper is withdrawn from the cutter. This ensures that withdrawal of the continuous paper from the cutter occurs at an appropriate timing. In the case where a stepping motor is adopted as a motor for driving the cutter, the following configuration can be used. Whether the cutter is in the cutting-termination position or not is detected from the number of steps by which the stepping motor is driven.

Description

technical field [0001] The present invention relates to a continuous paper cutting device, and more particularly, to a continuous paper cutting device that controls the position of the continuous paper relative to the position of the paper cutter when cutting the continuous paper. Background technique [0002] In the conventional cutting apparatus for continuous paper, even after the continuous paper is cut, the continuous paper remains at the cut position. Therefore, there is a case where the cutter contacts the surface of the continuous paper when the cutter is returned to its original position, with the result that the cutter blade scrapes the surface of the continuous paper, resulting in a problem of generation of paper dust. [0003] In order to overcome this problem, it is necessary to control the cutter position and the continuous paper position. The following is a technical example on this issue. [0004] According to one example of this technology, a cutting devic...
