To solve the problem of information reproducing suspension due to the failure of reproducing time control in the case of losing boundary information when a boundary time error, reproduced information switching or the like occurs if a flag indicating presence of a boundary in reproducing time information is only added during the reproduction of a plurality of reproducing information sets without any apparent joints.

This device is provided with the counting means 14 of a plurality of bits for counting the number of times of reaching boundary instruction information of a reproducing information set. The output of the counting means 14 accompanies a reproducing time, whereby reproducing information set numbers are provided by all reproduction units at the reproducing time. Thus, time control can be carried out even when the boundary itself is lost.
