FIELD: electricity.
SUBSTANCE: engraving device has a housing in which is mounted a stepper motor, on the shaft of which there is a hammer with a diamond needle rigidly attached to first and second magnets, wherein the device has third and fourth magnets oriented relative the first and second magnets such that the first and third, as well as the second and fourth magnets repel each other in pairs, wherein the first and second magnets are attached to the hammer on the right side and left side of said shaft, and the third and fourth magnets are attached to the housing, wherein the first and second, as well as the third and fourth magnets are oriented in pairs relative each other such that said repelling forces of their interaction have a component lying in the plane of motion of the hammer.
EFFECT: simple design and high stability of operation of the engraving device.
