WIPO Patent Application WO/2023/017789
Kind Code:
A1
Abstract:
This invention optimally reciprocates a cutting blade. In this motorized cutting machine 10, a control unit 100 detects an initial position and a reversing position on the basis of a detection signal from a lifter detection switch 68, and the rpms of the motor 50. Namely, the motor 50 is drive-controlled by means of the control unit 100 to allow the travel of a lifter 65 and a blade 72 to be halted in the initial position and the reversing position. As a result thereof, for example, without providing a switching mechanism or the like for switching between disconnected and connected states of the path transmitting the motor drive force to the lifter, the lifter 65 can be halted or reversed in the reversing position. Accordingly, the lifter 65 and the blade 72 can be made to travel optimally.
