摘要:
A display for measured quantities can include a gauge with a set of indicia spaced around the gauge to indicate the measured quantities. A window can be formed in the gauge that extends along the set of indicia. An elliptical reflector can be positioned such that a first focus of the elliptical reflector is on the same axis as the center of the gauge with this axis perpendicular to the axis connecting the foci. An optical device can be mounted on a shaft and be arranged to redirect a light beam from a second foci of the elliptical reflector onto the elliptical reflector to generate a virtual pointer in the window. Means can be provided for turning the shaft to rotate the optical device. A light source can project the light beam onto the optical device. Rotation of the optical device can enable the virtual pointer to be selectively aimed at the set of indicia.

摘要:
For accurate correlation of the punch pins and edge guide for a paper punch or the like, a gage sheet of predetermined length is formed with accurately located holes corresponding to the desired location of the holes or slots to be punched in paper of similar length (e.g., end holes equidistant from top and bottom of the sheets). Such gage sheet may be pre-punched and of a permanent character, or may be prepared by trial and error by adjusting the edge guide until the end holes are equidistant from the edges of the sheet. The punch pins are lined up with the gage holes and then the edge guide is moved snugly against the edge of the gage. The gage is then removed. The edge guide is mounted on a transversely movable slide visible through a window in the platen on which the paper is to rest. Markings for different paper lengths may be permanently displayed on the platen at an edge of the window. Markings on the platen may be affixed by applying thereto a decal having paper length markings thereon. Accurate positioning of the edge guide after factory assembly is thus possible. In the preferred embodiment, a mark is placed on the slide in line with the marking on the platen corresponding to the particular length of the gage. Preferrably, such mark on the slide is affixed to a decal which is placed on the slide in the proper location.
