发明名称 Length measuring apparatus
摘要 A length measuring device which includes a carrier body and a measuring band is provided with fastening components which secure the two ends of the measuring band to respective ends of the carrier body. One of the fastening components is provided with a tensioning device for the measuring band. The other fastening component at the other end of the measuring band is fixed to the measuring band by means of screws. A particular geometry is disclosed which results in a flat, low profile configuration for the second fastening component. Because of the unique shape of the second fastening component, the scanning unit, which is longitudinally slideable in the interior of the carrier body, can be removed from the end of the carrier body past the second fastening component without disassembling or readjusting or disturbing the measuring band. The carrier body can be built up from an array of individual components, in which case the measuring band is preferably held in place only on the outer ends of the two end components. Throughout the length of the carrier body, the measuring band is received freely in a groove defined in the carrier body.
