Abstract: A light emitting display apparatus has pixels arranged in rows to display a predetermined image, each of the pixels being composed of red and green, or blue and yellow light emitting diodes, lenses provided on the pixels, each of the lenses horizontally diffusing lights emitted from the red and green, or blue and yellow light emitting diodes, and vertically diverging the lights, a driver for driving the red and green, or blue and yellow light emitting diodes to be turned on in accordance with predetermined light intensities, thereby representing various colors including a white color. In the light emitting display apparatus, therefore, the displayed image is easy to be recognized, the number of the LEDs and the power consumption are decreased, and the density of pixels is increased.

Abstract: A leaf type indicating device provided with a synchronizing piece made of a spring material, rotatably mounted on a main shaft and having a side portion engageable with a lug formed on one leaf belonging to a first indicating leaf group having a large number of turns per unit time, a bent portion engageable with at least one leaf belonging to a second indicating leaf group arranged adjacently to the first indicating leaf group and having a small number of turns per unit time and an end portion inserted in a hole formed in a body frame and connected with the body frame in order to make the manufacture at a low cost possible.
