ABSTRACT:
A copying apparatus is connected to active and stand-by sections (11, 12) each of which has a specific data signal. The active section has a memory unit (14) for memorizing a plurality of data signals and an accessing unit (13) for accessing the memory unit to read one of the data signals as the specific data signal out of the memory unit in a readout operation. The accessing unit produces readout information which is representative of the readout operation. The copying apparatus comprises a memory section (23) of a first-in-first-out fashion that successively memorizes the specific data signal of the active section as a copied data signal up to a predetermined data number. A monitoring section (24) monitors the memory section to produce a monitored signal when the number of the copied data signals is equal to the predetermined data number. A control section (31) controls the memory section in response to the monitored signal and the readout information to make the memory section stop memorizing the specific data signal of the active section as the copied data signal.
