Abstract

PURPOSE: To control the unit so that the relation between the page and data position can always be the same, by obtaining the readout head address of the memory unit from the value of the end address register and the output of the page address register.
CONSTITUTION: The unit consists of the switch 21 to set the page No, page address register 22 implanting the head address of each page, end address register 23 containing the end address of the recording data, adder 24 adding the content of the page address register with the content of the end address register to obtain the head address of the designation page, and address counter 25 counting the readout address of the memory unit as the initial value for the output of the adder. Even if the data location of the memory unit is changed every recording, the control can be made so that the relation between the page and data position can always be the same.
