Pictures, whose movement is slightly changed, are provided on the outer surface of the tape scale body 5. A window 6 is formed in a case surface 1A, which faces a horizontal part 5a of the tape scale body 5. A driving drum 8 is linked to the drum 4 throgh a gear type rotation transmitting mechanism 7 having an intermediate gear 7a. A gear shaft 71 of the intermediate gear 7a is supported by a bearing part. A long hole 10 is provided on the bearing part and opened from an engaging position to a separated position against a gear shaft regulating spring 9 when the tape scale body 5 is drawn out.
