Abstract
Abstract A printing mechanism is mounted within a hand positionable housing. Relative motion between the printing mechanism and the medium on which printing is to be performed is sensed. A control device responds to these movement indicating signals to generate command signals for appropriately actuating the printing mechanism.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
A hand motivated printer for printing symbols upon a surface of a recording medium comprising: a. a manually manipulatable housing for permitting relative motion between said housing and said medium, b. printing means carried by said housing, c. a signal source coupled for introducing print command signals to said printing means, d. a roller means carried by said housing for frictionally engaging said medium, and e. emitter means responsive to said roller means for generating enabling signals timed in synchronism with predetermined displacements of said printer over the surface of said medium, said enabling signals being transmitted for enabling said signal source, said emitter means including: i. a rotatable disk having apertures therein, said disk being driven by said roller, ii. a light source pOsitioned to transmit light through each of said apertures sequentially during rotation of said disc, and iii. a photoelectric device positioned for exposure to light passing through said apertures for generating said enabling signals on exposure to said light.
Claim 2
Dependent Claim
163 words
A hand motivated printer for printing symbols upon a surface of a recording medium comprising: a. a manually manipulatable housing for permitting relative motion between said housing and said medium, b. printing means carried by said housing, c. a signal source coupled for introducing print command signals to said printing means, d. a roller means carried by said housing for frictionally engaging said medium, and e. emitter means responsive to said roller means for generating enabling signals timed in synchronism with predetermined displacements of said printer over the surface of said medium, said enabling signals being transmitted for enabling said signal source, said emitter means including: i. a rotatable disk having apertures therein, said disk being driven by said roller, ii. a light source pOsitioned to transmit light through each of said apertures sequentially during rotation of said disc, and iii. a photoelectric device positioned for exposure to light passing through said apertures for generating said enabling signals on exposure to said light.
Claim 3
Dependent Claim
143 words
A manually motivated printer for printing symbols upon a surface of a recording medium in accordance with sequences of print command signals from a signal source comprising a print head responsive to said print commands for impressing a matrix of print elements upon said medium into characters representing said symbols, a manually manipulatable housing for permitting relative motion between said housing and said medium, said print head being carried by said housing, roller means carried by said housing for frictionally engaging said medium, an emitter device coupled to said roller means for generating signals indicative of relative motion between said housing and said medium, means for coupling said emitter device signals to said signal source for controlling the generation of said print command signals in correlation with said relative motion, and means for coupling said controlled print command signals to said print head.
Claim 4
Dependent Claim
143 words
A manually motivated printer for printing symbols upon a surface of a recording medium in accordance with sequences of print command signals from a signal source comprising a print head responsive to said print commands for impressing a matrix of print elements upon said medium into characters representing said symbols, a manually manipulatable housing for permitting relative motion between said housing and said medium, said print head being carried by said housing, roller means carried by said housing for frictionally engaging said medium, an emitter device coupled to said roller means for generating signals indicative of relative motion between said housing and said medium, means for coupling said emitter device signals to said signal source for controlling the generation of said print command signals in correlation with said relative motion, and means for coupling said controlled print command signals to said print head.
Claim 5
Dependent Claim
36 words
A printer in accordance with claim 2 wherein said means for coupling said emitter device signals further includes switching means for selectively preventing coupling of said sensing means signals whenever printing is not to be performed.
Claim 6
Dependent Claim
19 words
A printer in accordance with claim 3 wherein said switching means is mounted on said housing for manual operation.
