A tape measure having an end hook capable of easily holding an object to be measured is proposed. A measuring strip is a self-sustaining metal strip formed with a convex section which has scale marks put thereon and painted. The end hook is a metal plate bent at a right angle and secured with rivets to the end of the measuring strip. A friction plate is a metal plate having an unevenly etched surface which is attached to the inside surface of the end hook by the use of an adhesive, double-coated tape. The uneven surface of the end hook is effective for holding the object to be measured.

Tape measure

A digital tape measure comprising a tape stored in a case when it is not used and drawn out of an aperture of the case when it is used and onto which a plurality of detection marks are affixed at equivalent interval, a detector of detecting the detection marks by photoelectric transfer elements, a counter of counting the detected signal being output from the detector corresponding to the volume of movement of the tape, a display of displaying the result counted by the counter, and in which a length of each detection mark is established to be a length twice as long as the minimum scale of the tape, the distance between each detection mark is established to be equivalent to the length of each detection mark in the direction of measurement, and the detector comprises two photoelectric transfer elements arranged at the phase difference of 90.degree. and a discriminator of discriminating the output signal from the photoelectric transfer elements.
