Abstract: PURPOSE:To obtain irradiating light near to desired spectral characteristic, having small color correction amount and having the spectral characteristic that a light utilization effect becomes high as a result by arranging two kinds of light valves respectively having different spectral characteristic at the 1st focusing position and the 2nd focusing position of an elliptical reflector. CONSTITUTION:In this illuminating device using the elliptical reflector 11 as a reflection mirror, two kinds of light valves 12a and 12b respectively having different spectral characteristic are arranged at the 1st and the 2nd focusing positions of the reflector 11. Synthesized light of the 1st and the 2nd light valves 12a and 12b is made parallel beams by a lens 13. By adding the spectral characteristic of the 1st light valve 12a to the spectral characteristic of the 2nd light valve 12b, the light is color-corrected and obtained as one having the spectral characteristic near to the desired spectral characteristic. Therefore, the correction amount in color correction by the reflector or a dichroic filter is small, as a result, the utilization efficiency of the light is improved. It is satisfactory to use a cold mirror as the reflector 11 in order to restrain the temperature rise of the light valve.

Inventor: AOYAMA YUUICHI
IPC: B65H31/02
Filed: 1979-04-18
Abstract: PURPOSE: To achieve the reduction in size and weight and the improvement in operating characteristic by moving the paper discharge tray which receives the transferred transfer paper to the  position covering the upper side of a transfer paper table at the stop of transfer process thereby  enabling the same to be used as a cover for the transfer paper table.   
     CONSTITUTION: The base end part 72a of a paper discharge tray 72 is pivotally fitted to a substrate 11 by way of a support shaft 73. Since the gravity W of the paper discharge tray 72 acts  upon the pressure protruding piece 74 provided in the position slightly away from the support  shaft 73, centering at the support shaft 73, clockwise moment is held applied to the tray 72 at all  times. The clockwise turn of the pressure protruding piece 74 is inhibited by the detention member 75 pivotally fitted to the support shaft 73 and the tray 72 is held in the position B where it  receives the transfer paper A. When the detention member 75 is forcefully turned clockwise, the  end parts of the hook piece 76, support shaft 73 and protruding arm 75b align straightly and  reaches the dead point position, but when it is further turned beyond this, the tensile force of a  spring 77 is given and the clockwise moment acts upon the detention member 75 to apply downward pressing force to the tray 72 which then comes to the stop position C and becomes a cover  for a transfer paper table 41.
