Abstract

A digital measuring device having a relatively rigid slide and a flexible, substantially transparent band with opaque indicia placed thereon, the band being capable of being pulled centrally through an opening in the slide. The slide houses a plurality of optic fibers with one end of each fiber terminating at a light-receiving panel and the other end of each fiber terminating at a digital read-out panel. The ends of the fibers at the digital read-out panel are arranged to form, e.g., a generic "88" configuration, from which the digits 0-99 may be formed. In operation, the band is pulled through the opening in the slide and light passes through the transparent areas of the band and into the light receiving panel. The light continues through the optic fibers and lights up a particular digital configuration at the digital read-out panel. The slide and band may be useful e.g., as a belt-like device for measuring one'"'"'s waist, or as a carpenter'"'"'s tape measure.

Claims

1. A device for measuring an object, comprising:

(a) a slide having;

(i) a light receiving panel,

(ii) a digital read-out panel with a digital configuration therein,

(iii) a plurality of optic fibers extending from the light receiving panel to the digital read-out panel, and

(iv) an opening formed in the slide; and

(b) an elongated substantially transparent band with opaque indica located thereon positioned in the opening, the opaque indicia corresponding to predetermined measured lengths of the band, wherein when the band is passed through the opening in the slide and across the light receiving panel, the opaque indicia mask some of the light while other light passes through the transparent area of the band and into certain of the plurality of optic fibers to selectively light the digital configuration at the digital read-out panel.

2. The device of claim 1, wherein the band has a first end and a second end, the first end having an L-shaped attachment for abutting an object to be measured.

3. The device of claim 2, wherein the light receiving panel and the digital read-out panel are in the same plane.

4. A digital waist measuring device, comprising:

(a) a buckle having;

(i) an ambient light receiving panel,

(ii) a digital read-out panel with a digital configuration therein,

(iii) a plurality of optic fibers each having a first end and a second end, the first end being connected to the light receiving panel and the second end being connected to the digital read-out panel, and

(iv) a continuous opening formed in the buckle; and

(b) an elongated substantially transparent belt with opaque indicia located thereon positioned in the opening, the opaque indicia corresponding to predetermined measured lengths of the belt, wherein when the belt is passed through the opening and across the light receiving panel the opaque indicia mask some of the ambient light while other ambient light passes through the transparent area of the belt and into certain of the plurality of optic fibers to selectively light the digital configuration at the digital read-out panel.

5. The device of claim 4, wherein the belt has a first end and a second end, the first end being fixedly attached to the buckle and the second end being a free end.

6. The device of claim 5, wherein the light receiving panel and the digital display panel are in perpendicular planes.

7. The device of claim 6, wherein the light receiving panel is covered by an opaque hinged door to selectively prevent light from passing into the light receiving panel.
