Abstract
A scribing apparatus which forms a scribe line on a work comprises a scribe body having a cutter put on the work and a vibration generation member which vibrates the cutter in a direction perpendicular to the work periodically, a support device having a support body for supporting the scribe body to be movable, and magnetic force applying means for holding the scribe body at a standard height in the direction by using magnetic force. The magnetic force applying means includes a pair of magnets and a pair of magnets repulsing each other in a direction parallel to a direction in which the vibration generation member vibrates. And magnetically repelling force applied to the scribe body by said first pair of magnets and magnetically repelling force applied to the scribe body by said second pair of magnets oppose to each other.
