Abstract
A plurality of rotatable members are formed with patterns of given shapes which permit the passage of a laser beam, and which are arranged in concentric circles about the axis of rotation of the members. Part of each rotatable member is disposed in the path of the laser beam so that a combination of the individual patterns on the respective rotatable members define a pattern to be printed or marked. In this manner, a variety of printing or marking patterns can be easily obtained by merely controlling the angular position of the respective rotatable members.

A pattern controlling device for a laser marker in which a laser beam is profiled to a given printing pattern which is marked on the surface of an object;
- the pattern controlling device comprising a plurality of discs which are rotatably mounted in coaxial relationship and each formed with given patterns which permit the transmission of the laser beam therethrough, each of the rotatable discs being partly disposed in a path of passage of the laser beam so that the patterns on the individual rotatable discs are combined to define the printing pattern, in which the patterns which permit the passage of the laser beam therethrough are formed in patterned discs which are applied to a plurality of circular slots disposed in each rotatable disc in a concentric circle and centered about the axis of rotation of the rotatable discs and at an equal interval.
A pattern controlling device for a laser marker in which a laser beam is profiled to a given printing pattern which is marked on the surface of an object;
- the pattern controlling device comprising a plurality of rotatable discs disposed in coaxial relationship, a counter mechanism which causes each of the rotatable discs to rotate through a given angular increment whenever another adjacent rotatable disc located on one side thereof has rotated through one revolution, and a plurality of index wheels carrying given indicia or numerals and adapted to be moved together with the respective rotatable discs, each of the rotatable discs being formed with given patterns which permit the passage of the laser beam therethrough, the individual rotatable discs being partly disposed in a path of passage of the laser beam so that the patterns of the individual rotatable discs are combined to define the printing pattern.
A pattern controlling device for a laser marker in which a laser beam is profiled to a given printing pattern which is marked onto the surface of an object;
- the pattern controlling device comprising a plurality of rotatable discs disposed in coaxial relationship, a counter mechanism for rotating each rotatable disc through a given angular increment whenever another adjacent rotatable disc located on one side thereof has rotated through one revolution, a drive mechanism for driving the counter mechanism, and a plurality of index wheels carrying given indicia or numerals and each adapted to be driven as a corresponding one of the rotatable disc rotates, the respective rotatable discs being formed with given patterns which permit the passage of the laser beam therethrough, the respective rotatable discs being partly disposed in a path of passage of the laser beam so that the patterns on the individual rotatable discs are combined to define the printing pattern.
A pattern controlling device for a laser marker in which a laser beam is profiled to a given printing pattern which is marked on the surface of an object;
- the pattern controlling device comprising a plurality of rotatable discs disposed in coaxial relationship, a counter mechanism for rotating each rotatable disc through a given angular increment whenever another adjacent rotatable disc located on one side thereof has rotated through one revolution, a drive mechanism for driving the counter mechanism, a plurality of index wheels each associated with one of the rotatable discs and carrying given indicia or numerals, the wheels being driven as the associated rotatable disc rotates, each of the rotatable discs being peripherally formed with a plurality of notches which are engageable with a stop pin, the respective rotatable discs being formed with patterns which permit the passage of the laser beam therethrough, the respective rotatable discs being partly disposed in a path of passage of the laser beam so that the patterns on the individual rotatable discs are combined to define the printing pattern.
