Abstract

PURPOSE:To relieve the limitation of the length of an interface cable between a recorder and a controller, by temporarily accumulating writing data in a memory by receiving them in advance, and recording them by successively reading out them. CONSTITUTION:When a write mode signal is generated from a writing controlling circuit 6 and a recorder starts its writing operation, a data request signal is sent from the circuit 6 to a controller, and a data deliver signal of one byte one byte supplied from the controller is planted in a memory 2 through a receiving circuit 1. At the same time, a memory writing address controlling circuit 3 counts the received data deliver signal and updates a memory writing address to be written in the memory 2. Whenever data are read out from the memory 2, a data readout address of the memory 2 is updated by a memory reading address circuit 4. The data and read out from the memory 2 are sent to a recording section through a writing circuit 5.
