Abstract: This invention relates to a light shield/support device for reducing glare on the lighted display window of a portable electronic calculator. The device may also be interchangeably utilized to support the calculator in an inclined position which also tends to reduce the glare on the display window as well as making operation of the keyboard and positioning of the calculator on a disk top more convenient. The device includes a pair of spaced shank members having inclined upper ends having an inclined flange member carried therebetween. Attachment means are carried by a lower end of the shank members for engaging opposing side walls for securing the device to the calculator. The shank members are of sufficient length to support the flange member above and across the display window or below and across the bottom of the calculator for selectively utilizing the device as a light shield or as a support.
