Abstract

PURPOSE: To adequately catch the timing of replacement for a roll-shaped recording material of facsimile or the like, by detecting its residual amount, that is, by detectively counting read marks arranged at a required interval and displaying the residual amount.
CONSTITUTION: A read mark 15 is further provided in a roll material 5 from its start end 51 to the final end at every fixed distance in the right end of an opposite side B to a recorded side A. When this roll material 5 is carried in and recorded, the read mark 15 is detected by a source 7 of light and read sensor 8 in accordance with conveyance of the material, and its interrupted signal is counted by a counter circuit as a passing amount, if this amount is subtracted from known total quantity of the read mark, a residual amount of the roll material 5 can be displayed. Further this read mark is constituted as a number of bits having information of length from the final end, then a display of the residual amount can be more accurately performed.
