TIME DATA ADDING APPARATUS

PURPOSE:To reduce memory capacity and to achieve miniaturization by storing only data and adding the time data formed corresponding to the stored data at the time of reproduction to the stored data. CONSTITUTION:Time original data T is inputted to a timer circuit 2A as a synchronous signal at a cycle T and this input signal is used as a trigger to count a clock signal (c) and a time timing signal 2a whose cycle becomes (t) is generated. In this time data adding apparatus, time forming original data (b) is inputted simultaneously with the start of reproduction in order to generate no shift between the memory data 1a of a memory device 1 and the time data 2b from a time forming device 2 and, on the basis of this time forming original data (b), the synchronism of the time original data (T) (synchronous signal) with data forming time is taken. Therefore, the time data can be added to the stored data and memory capacity is reduced to achieve miniaturization.
