A display source unit for a display device in a vehicle is provided, by
which the driver is not given a physical or mental oppressive feeling to
his or her head upon getting on and off the vehicle. The display source
unit 9, which irradiates a light of a display image containing instrument
information on a combiner 7 situated in front of an eye point I so that
the irradiated light can be seen as a virtual image S from the eye point
I, is provided with a cover member 13 consisting of: a front cover body 15
putting an optical element 21 for image magnification thereonto; and a
rear cover body 17 hinged to the front cover body 15 with receiving a
display device 23 therein. The cover member 13 is folded, thereby the
light of the display image displayed on a display surface 23a of the
display device 23 is reflected on a reflector 25 disposed in the cover
member 13 to the optical element 21, passes through the optical element
21, and goes toward the eye point I after being reflected by the combiner
