Abstract
Abstract An apparatus for controlling a pulse generator includes a sensor cooperating with a rotary detecting plate for generating a pulse, as for defining the timing for the printing operation. An indexing gear faces one side of the detecting plate, and is formed by a rotary member on which the detecting plate is supported. A plurality of indexing pins are provided on the one side of the detecting plate and engaged with teeth on the indexing gear. The pins are disengageable from those teeth and engageable with other teeth on the indexing gear by rotation of the detecting plate relative to the indexing gear. A spring normally urges the detecting plate in engagement with the indexing gear.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
An apparatus for controlling a pulse generator, comprising: a sensor cooperating with a rotary detecting plate for generating a pulse; an indexing gear facing one side of said detecting plate and comprised of a rotary member on which said detecting plate is supported; a plurality of indexing pins provided on said one side of said detecting plate and engaged with teeth on said indexing gear, said pins being disengageable from said teeth and engageable with different teeth on said indexing gear by rotation of said detecting plate relative to said indexing gear; and a spring urging said detecting plate in engagement with said indexing gear.
Claim 2
Independent Claim
105 words
An apparatus for controlling a pulse generator, comprising: a sensor cooperating with a rotary detecting plate for generating a pulse; an indexing gear facing one side of said detecting plate and comprised of a rotary member on which said detecting plate is supported; a plurality of indexing pins provided on said one side of said detecting plate and engaged with teeth on said indexing gear, said pins being disengageable from said teeth and engageable with different teeth on said indexing gear by rotation of said detecting plate relative to said indexing gear; and a spring urging said detecting plate in engagement with said indexing gear.
Claim 3
Dependent Claim
39 words
An apparatus as set forth in claim 1, wherein said detecting plate has a plurality of detecting slits having an angular pitch θ 1 which differs from the angular pitch θ 2 of said teeth on said indexing gear.
Claim 4
Dependent Claim
