Abstract
A scribing device for forming a scribe line on a work comprises a vibration generator for generating vibration, a cutter for cutting a work by utilizing vibration thereof, a shaft extending vertically from the vibration generator so as to transmit the vibration of the vibration generator to the cutter, a guide unit for guiding a linear motion of the shaft in a central axis direction thereof, and a load adjusting mechanism for adjusting a load applied to the work from the cutter, the load adjusting mechanism being operated by magnetic force. According to such scribing device, the guide unit guides a vertical moving (rising) motion of the shaft by the load adjusting mechanism and guides the vibration of the shaft caused by the vibration generated by the vibration generator.
