<p>PURPOSE:To easily recognize in vision a tape running position irrespective of a normal direction and a reverse direction running by selectively driving a display section for a tape normal direction running and reverse direction running constituted of arranging plural illumination sections in rows, illuminating and displaying them in the same formation. CONSTITUTION:Pulse generating sections 21, 22 generate respectively pulse signals in periods corresponding to rotating speeds of reels to be a tape take-up side and a feed side during a normal direction running. During the tape normal direction running, a switch 18 is connected to a fixed end 181 and a display section 16 is in a driven condition. When the tape is situated at a position of beginning to wind, the ratio of pulse numbers N1, N2 per unit time of respective pulse signals of the pulse generating sections 21, 22 becomes the smallest, a calculation circuit 20 outputs an H signal from an output end O6 and an LEDD1 lights up. When a tape running progresses, the value of N2/N1 is successively larger, the calculation circuit 20 outputs the H signal from an output end O5 in order, and from an LEDD2 to a D6 successively light up. During a reverse direction running, a display section 17 is driven, and from an LEDD7 to a D12 are successively light up.</p> |
