  • Patent number: 4773783
    Abstract: A keyboard has an attitude adjusting mechanism with a shaft extending lengthwise along the rear inside of the case. The shaft allows the legs to be adjusted remotely from the adjusting mechanism. Two legs are mounted on the shaft and extend through holes in the bottom rear of the case to raise and lower the rear of the case as the shaft is rotated. The adjusting mechanism is indexed by rotatable flats on the shaft which mate with complementary flats in the case to lock the mechanism in its index positions. A holder for a flexible strip label on the keyboard has a finger slot for access to the label so that it can be removed from its holder.
