Abstract
A half-cut device including: a half cutter for cutting a main tape or a released tape of a processed tape which the released tape is affixed to the main tape; a stepping motor for driving the half cutter to cut; and a motor control unit for controlling the stepping motor, wherein the motor control unit controls the stepping motor to maintain the condition which the half cutter cuts the main tape or the released tape for a predetermined time.
Claims11
A half-cut device comprising:
- a half cutter for cutting a main tape or a released tape of a processed tape which the released tape is affixed to the main tape;
- a stepping motor for driving the half cutter to cut;
- and
- a motor control unit for controlling the stepping motor,
- wherein the motor control unit controls the stepping motor to cause the half cutter to contact the processed tape and then increases a cutting torque of the stepping motor until the cutting torque is stabilized at a step-out torque for the stepping motor, and
- wherein the step-out torque at which the half cutter cuts the main tape or the released tape is maintained for a predetermined time.
A control method for a stepping motor providing a power source for a half cutter cutting a main tape or a released tape of a processed tape which the released tape is affixed to the main tape, comprising:
- controlling the stepping motor to cause the half cutter to contact the processed tape, and
- increasing upon contacting the processed tape, a cutting torque of the stepping motor until the cutting torque is stabilized at a step-out torque for the stepping motor,
- wherein the step-out torque at which the half cutter cuts the main tape or the released tape is maintained for a predetermined time.
