Classification: CPC B | IPC B

Claim 0:
1. A cutting device comprising:
a placement member, an object to be cut being placeable on the placement member;
a mounting portion, a cutting blade being mountable to the mounting portion;
a first movement mechanism configured to relatively move the object to be cut placed on the placement member, and the mounting portion in a first direction and a second direction, the second direction being opposite to the first direction;
a second movement mechanism configured to move the mounting portion in a third direction causing the mounting portion to move closer to the placement member, and a fourth direction causing the mounting portion to move away from the placement member, the third direction and the fourth direction intersecting the first direction and the second direction;
a pressure applying mechanism configured to apply pressure to the mounting portion in the third direction, in accordance with a movement of the mounting portion by the second movement mechanism;

a control portion configured to control the first movement mechanism and the second movement mechanism; and
a memory having computer-readable instructions stored thereon that when executed by the control portion, instruct the control portion to perform processes comprising:
moving the mounting portion, by controlling the first movement mechanism, to a facing position at which the cutting blade faces the object to be cut and the cutting blade is separated, in the fourth direction, from the object to be cut;
moving the mounting portion in the third direction from the facing position by controlling the second movement mechanism;
detecting, in a course of the mounting portion moving in the third direction, a pressure correspondence value corresponding to the pressure in the third direction applied to the mounting portion by the pressure applying mechanism, and a movement amount of the mounting portion in the third direction;
deciding a cutting pressure correspondence value, on a basis of the pressure correspondence value and the movement amount after the cutting blade has come into contact with the object to be cut, of the detected pressure correspondence value and the detected movement amount, the cutting pressure correspondence value being the pressure correspondence value corresponding to a cutting pressure applied to the mounting portion by the pressure applying mechanism when cutting the object to be cut using the cutting blade;
acquiring cutting data for cutting a pattern from the object to be cut; and
controlling the first movement mechanism and the second movement mechanism in accordance with the acquired cutting data, applying the cutting pressure corresponding to the decided cutting pressure correspondence value to the mounting portion, using the pressure applying mechanism, and cutting the object to be cut, using the cutting blade mounted to the mounting portion.
