Apparatus and method for coding objects
First Claim
1. A method of providing a recording of information on an object comprising the steps of:
- predeterminately locating an object and a source of intense radiant energy with respect to each other wherein said radiant energy is generatable in the form of a pulsed radiant energy beam and whereby beam energy from said source may be caused to scan a selected area of the surface of said object defining at least one strip-like track portion of said object'"'"'s surface,scanning and detecting a selected portion of the object when said selected portion is predeterminately located with respect to said source of radiant energy, andgenerating a control signal when such detection is made,applying said control signal to cause the reproduction of selected information signals defining a code from a memory, andutilizing said selected information signals which controlling relative movement between said beam and said object to pulse the radiant energy generated by said source and to cause pulses of said radiant energy so generated to effect radiation recording of indicia along space-separated areas of the surface stratum of the object defining a record track containing such indicia extending in the direction of relative movement between the object and the beam of said radiation directed thereat.

Abstract
An apparatus and method are provided for applying code recordings to objects, such as record members and the like, for computing, identifying, pricing, routing and other functional purposes such as those associated with record keeping, classifying, storage and controlled movement of such articles. In one form, a selected portion of a record member is detected by a sensing device which generates a signal which is applied to a code generating and control device which operates thereafter to control the operation of one or more radiation generators, such as laser or electron beam generating devices, in a manner to generate a series of energy pulses which are directed at the record member or object and serve to burn, discolor or otherwise record pulse codes along one or more tracks of the objects. The objects coded may comprise flat cards, envelopes, record strips, containers or otherwise shaped articles of manufacture. In a particular form, cards, other devices or coatings are attached to objects and are coded by automatic beam pulsing means for identifying such objects.

12. A method for providing a recording on an object comprising the steps of:
-
predeterminately locating an object and a source of intense radiant energy with respect to each other wherein said radiant energy is generated in the form of a pulsed radiant energy beam and whereby beam energy from said source may be caused to scan a selected area of the surface of said object, identifying said object when it is at a scanning station, and generating a control signal when such identification is made, applying said control signal to selectively reproduce selected information signals defining a code from a memory containing a plurality of code signal recordings, so as to effect the generation of predetermined information defined by said code, and utilizing said selected information signals while controlling the relative movement between said object and said source of intense radiant energy to pulse said beam of radiant energy so as to cause said beam to record a plurality of spot-like areas in the surface stratum of said object and to thereby effect a pulse code recording along the portion of the surface of the object intersected by said beam.

13. A method of recording information on objects comprising:
-
securing a layer of a recording material on a select portion of the surface of an object on which select portion an information recording is to be effected, relatively moving said object and a source of intense beam radiation capable of effecting a recording in said recording material secured to said object, and when said radiation source and said object are predeterminately positioned with respect to each other, detecting such relative positioning and generating a control signal and applying said control signal to effect the reproduction of information signals from a memory and applying said information signals to intensity modulate radiation from said source so as to variably generate said radiation beam while said predetermined relative movement is effected between the beam of radiation and said object such that said radiant energy beam intersects and selectively records information along a select portion of said recording material secured to said object so as to define a predetermined recording in said recording material.

-
predeterminately relative positioning a radiation beam generating means and an object to be recorded on by means of radiant energy generated by said generating means, detecting when such predetermined relative positioning is effected between said radiation beam generating means and said object and generating a first recording cycle initiating control signal upon detecting said predetermined relative positioning, applying said control signal to address a memory containing information recorded therein and defining different indicia to be recorded on said object and reproducing select information from said memory as coded electrical control signals, generating a beam of recording radiation by energizing said radiation beam generating means and controlling same in a manner to cause said beam to intersect a first portion of said object and effecting relative scanning movement between said beam and said object while applying a first group of select electrical control signals derived from said memory to selectively control said radiation beam during the relative scanning movement between said beam and said object in a manner to effect the recording of first indicia on a first select portion of said object, thereafter generating further select groups of indicia defining control signals derived from said memory in synchronization with further relative scanning movement between said radiation beam and said object and applying said further select control signals to further control said beam to cause it to effect the recording of respective additional indicia on the surface of said object so as to define at least one line of indicia extending across a band-like area of the surface of said object.
