Abstract
A marking device comprises: a marking mechanism for marking a surface to be processed, of an object to be marked, by reciprocating a marking portion; a marking portion moving mechanism for moving the marking portion in two-dimensional directions along the surface to be processed; and a pressure adjusting circuit for keeping a constant pressure which the marking portion applies to the surface to be processed; wherein the marking mechanism comprises a cam mechanism for linearly reciprocating the marking portion by following a cam which is rotated by a driving member.
Claims10
A marking device comprising:
- a marking mechanism for marking a surface to be processed, of an object to be marked, by reciprocating a marking portion;
- a marking portion moving mechanism for moving the marking portion in two-dimensional directions along the surface to be processed;
- and
- a pressure adjusting circuit for keeping a constant pressure which the marking portion applies to the surface to be processed;
- wherein the marking mechanism comprises a cam mechanism for linearly reciprocating the marking portion by following a cam which is rotated by a driving member.
2 more elements
A marking method comprising the steps of:
- marking a surface to be processed, of an object to be marked, by following a cam which is rotated by a driving member to reciprocate a marking portion;
- moving the marking portion in two-dimensional directions along the surface to be processed;
- detecting a contact between the surface to be processed and the marking portion by a change in a value of a current flowing into the driving member;
- and
- keeping a constant pressure which the marking portion applies to the surface to be processed in accordance with the change in the value of the current, when the contact between the surface to be processed and the marking portion is detected in the detecting step.
2 more elements
A marking device comprising:
- a marking mechanism for marking a surface to be processed, of an object to be marked, by reciprocating a marking portion of which an end is vibrated;
- a marking portion moving mechanism for moving the marking portion in two-dimensional directions along the surface to be processed;
- and
- a pressure adjusting circuit for keeping a constant pressure which the marking portion applies to the surface to be processed;
- wherein the pressure adjusting circuit weakens the pressure which is applied to the surface to be processed, and stops vibrating the end of the marking portion, when a line to be marked is not continuous or when the marking portion moves between two positions in which each character is marked on the surface to be marked;
- and
- the marking portion moving mechanism moves the marking portion to a next position to be marked in the two-dimensional directions.

A marking method comprising the steps of:
- marking a surface to be processed, of an object to be marked, by reciprocating a marking portion of which an end is vibrated;
- weakening a pressure which is applied to the surface to be processed, to keep the pressure constant, and stopping vibrating the end of the marking portion, when a line to be marked is not continuous or when the marking portion moves between two positions in which each character is marked on the surface to be marked;
- and
- moving the marking portion to a next position to be marked in two-dimensional directions.
1 more element
A marking device comprising:
- a marking portion moving mechanism for moving a marking portion;
- a reciprocating mechanism for reciprocating the marking portion;
- a pressure control circuit for controlling a pressure which a marking portion applies to a surface to be marked;
- and
- wherein when the marking portion moving mechanism moves the marking portion without marking the surface to be marked, the reciprocating mechanism stops reciprocating the marking portion, the pressure control circuit weakens the pressure so as to hardly mark the surface to be marked, and the marking portion is moved along the surface to be marked.
