Claim 5

An automatic register mark printing control device in an engraving machine, comprising: register mark printing means whereby light applied to the register mark sections provided around a light-penetrating original image in a negative holder is selectively controlled by positioning said register mark printing means to produce either irradiated or non-irradiated condition, said register mark printing means generating a signal upon completion of every positioning operation; counter means responsive to the signal generated by said plural register mark printing means for counting the number of engraving operations in each of the X-axis and Y-axis directions during the engraving process; numerical value setting means for previously setting the numerical value of the number of segments to be engraved in both X-axis and Y-axis directions according to the engraving layout; comparison means responsive to said counter means when it exceeds its capacity and responsive to the set value of the number of segments to be engraved for generating a comparison means output; and, selective control means for selectively controlling said plural register mark printing means in response to the comparison means output.

Claim 6

An automatic register mark printing control device in an engraving machine, comprising: register mark printing means whereby light applied to the register mark sections provided around a light-penetrating original image in a negative holder is selectively controlled by positioning said register mark printing means to produce either irradiated or non-irradiated condition, said register mark printing means generating a signal upon completion of every positioning operation; counter means responsive to the signal generated by said plural register mark printing means for counting the number of engraving operations in each of the X-axis and Y-axis directions during the engraving process; numerical value setting means for previously setting the numerical value of the number of segments to be engraved in both X-axis and Y-axis directions according to the engraving layout; comparison means responsive to said counter means when it exceeds its capacity and responsive to the set value of the number of segments to be engraved for generating a comparison means output; and, selective control means for selectively controlling said plural register mark printing means in response to the comparison means output.

Claim 7

An automatic register mark printing control device in an engraving machine, comprising: register mark printing means whereby light applied to the register mark sections provided around a light-penetrating original image in a negative holder is selectively controlled by positioning said register mark printing means to produce either irradiated or non-irradiated, said register mark printing means generating a signal upon completion of every positioning operation; counter means responsive to the signal generated by said plural register mark printing means for counting the number of engraving operations in each of the X-axis and Y-axis directions during the engraving process; first numerical value setting means for previously setting the numerical values of the number of segments to be engraved in both X-axis and Y-axis directions according to the engraving layout; second numerical value setting means for prEviously setting the numerical value of the first stage of said counter means in both X-axis and Y-axis directions; first comparison means for comparing the number of engraving operations completed as counted by said counter and the set value of the number of segments to be engraved, as set on said first numerical value setting means; second comparison means for comparing the number of engraving operations completed as counted by said counter and the set value of the first stage of said counter as set on said second numerical value setting means; and selection control means further comprising a first AND gate in which the output of said first comparison means is AND-ed with a negative printing and exposing control signal to effect selective control of said register mark printing means and a second AND gate in which the output of said second comparison means is AND-ed with the negative printing and exposing control signal to effect selective control of said register mark printing means.
