するデジタル巻尺。 There is a measuring tape that is wrapped around a reel inside the case body and is always built into the case body, and can be freely pulled out from the case opening when taking measurements.
The measuring tape is hung around the circumference without slipping,
a measuring roller that converts the amount of pull-out of the measuring scale into a rotational amount; a rotary encoder that is connected to the rotating shaft of the measuring roller and encodes the rotational amount converted by the measuring roller; A counter that counts the output from the rotary encoder, a counter control circuit that calculates the output of the counter during measurement and performs predetermined control, and a display that digitally displays the output from the counter control circuit. In the digital tape measure, the measuring measure, which is elastically held so as to point toward the rotation center of the measuring roller and is wrapped around the circumferential surface of the measuring roller, is pressed against the circumferential surface of the measuring roller. A digital tape measure characterized by having multiple pinch rollers.
