Abstract
Abstract Automatic marking is accomplished by providing a housing that moves along a calibrated guide. The housing is operably connected with a microcomputer which receives preselected marking data. The housing carries a sensor and a marking device. As the housing moves along the guide, the sensor reads the calibrations and registers same with the data in the microcomputer. In response, the marking device applies appropriate marks on an associated object.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
Apparatus for marking preselected measurements on an object, comprising: a housing, a source of electrical energy operably connected with said housing; means for receiving and storing preselected data, said data means being a microcomputer operably connected with said housing and connected to said source of electrical energy; means for engaging and guiding movement of said housing relative to said object in a substantially straight line, said guiding means having calibrations at equally spaced intervals; means in said housing, connected to said energy source for electrically sensing said calibrations in response to said housing being moved relative to said calibrations and for registering said sensing with said preselected data; and means in said housing connected with said energy source for marking said object in response to said registered sensing of said calibrations, said marking means being electrically energized for urging a color-impregnated marking medium into repeated momentary contact with said object in a spaced marking pattern corresponding to said preselected stored data.
Claim 2
Dependent Claim
161 words
Apparatus for marking preselected measurements on an object, comprising: a housing, a source of electrical energy operably connected with said housing; means for receiving and storing preselected data, said data means being a microcomputer operably connected with said housing and connected to said source of electrical energy; means for engaging and guiding movement of said housing relative to said object in a substantially straight line, said guiding means having calibrations at equally spaced intervals; means in said housing, connected to said energy source for electrically sensing said calibrations in response to said housing being moved relative to said calibrations and for registering said sensing with said preselected data; and means in said housing connected with said energy source for marking said object in response to said registered sensing of said calibrations, said marking means being electrically energized for urging a color-impregnated marking medium into repeated momentary contact with said object in a spaced marking pattern corresponding to said preselected stored data.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 wherein guide pins extend from said housing into guide grooves formed in said guiding means.
Claim 4
Dependent Claim
21 words
The apparatus of claim 1 wherein said housing includes a keyboard and an LED display element operably connected to said microcomputer.
Claim 5
Dependent Claim
21 words
The apparatus of claim 1 wherein said calibrations are formed of a material compatible to be sensed by said sensing means.
Claim 6
Dependent Claim
10 words
The apparatus of claim 4 wherein said sensing is contact-free.
Claim 7
Dependent Claim
35 words
The apparatus of claim 1 including: a mechanical drafting apparatus, said apparatus having a straight-edge member, said straight-edge member being said guiding means, said housing being detachably mounted in sliding engagement with said straight-edge member.
Claim 8
Dependent Claim
21 words
The apparatus of claim 6 including: a scale of said calibrations detachably mounted on said straight-edge member adjacent said sensing means.
Claim 9
Dependent Claim
55 words
The apparatus of claim 6 including: one of a first and second scale of said calibrations is detachably mounted on said straight-edge member, said first scale having calibrations spaced by an interval of a first distance and said second scale having calibrations spaced by an interval of a second distance less than said first distance.
Claim 10
Dependent Claim
38 words
The apparatus of claim 1 including: a mechanical drafting apparatus having first and second straight-edge members relatively disposed at right angles, said housing being detachably mounted in sliding engagement with either of said first and second straight-edge members.
Claim 11
Dependent Claim
44 words
The apparatus of claim 1 including: a mechanical drafting apparatus having first and second straight-edge members and first and second ones of said housings, said first and second housings detachably mounted in sliding engagement with each of said first and second straight-edge members, respectively.
