Abstract

PURPOSE: To secure the decision for the effective or ineffective page code by providing the independent page detection part at the right and left pages each and then delivering the coincidence signal if the coincidence is secured for the codes through comparison of the output of the page detection parts.
CONSTITUTION: The output of left-side page detection part 4 is sent to page encoder 5 to be supplied to comparator circuit 9 along with the output of right-side page detection part 8. Then the coincidence signal is delivered outside by the right and left page codes and via driver 3. Now in case both the both pages are not lifted up, the coincidence is secured for the output codes between parts 4 and 8. Thus circuit 9 delivers the coincidence signal. In case the page alignment is in the course of execution, circuit 9 delivers no coincidence signal since the output codes differ between the both page detection parts. In such way, the decision is possible for the effective or ineffective page codes.
