The width of the bar is set at 1 or 2 centimeters, for example, and the length of the bar is considerably smaller than its width and equal to several millimeters, for example. The sensor 10 partly covers the fingerprint to be read and is contained in a supporter 12 which has an external connection pin 13. Furthermore, the sensor 10 has several rows of sensitive elements which are necessary for reconfiguration of a complete fingerprint image in a reading system.

Abstract: PURPOSE:To dispense with a special apparatus for diagnosis, by diagnosing the operating state of a speedometer by supplying an electric signal operating a tachometer to the speedometer. CONSTITUTION:The lead wires 5, 6 respectively connecting a speed signal source 1 and a speedometer 3 as well as a tacho signal source 2 and a tachometer 4 are cut and a lead wire 7 is connected in place of said lead wires 5, 6 and the tacho signal from the normal tacho signal source 2 is supplied to the speedometer 3.

In this state, the spot light source 131 is moved to a position corresponding to the index 51 by driving of a motor 135 and is lit for a prescribed time. The spot light source 131 is extinguished thereafter and is moved to the position of the index 52 along the first carriage 411 and is flickered for a prescribed time to display the copiable range corresponding to the set copy magnification. Thus, the copiable range is recognized easily though it is covered with the set original.
