INDICATOR

PURPOSE:To enable confirmation of multiple pieces of information without moving the point of view, by displaying multiple pieces of information in a specified space separate from each other. CONSTITUTION:A combination of numerals and graduations thereof indicating speed fixed photosentively and a combination of numerals and graduations thereof indicating revolutions of the engine done so are provided on the surface of a hologram 1. The combination are so arranged that the relief level from the surface of the hologram 1 differs from each other varies with the projection from a regenerated illumination source 2. A pointer 3 for speed indication and a pointer 4 for a tachometer is fastened on a double drive shafts 5 coaxially with each other, as examplified by the relationship of long and short hands of a timepiece and turned according to changes in the speed and revolutions. These pointers 3 and 4 are so positioned as to turn on the same plane as the one corresponding to the relief levels. As a regenerative illumination source 2 is lighted simultaneously with the start of an automobile, the speed display graduations 6 and speed display numerals 7 and revolution-number display graduations 8 and revolution-number indicating numerals 9 are displayed as individual relieved image in pairs on the plane.
