Abstract

A movable support tray apparatus for a computer keyboard includes a sliding member, a lift member, a tray member and an inclining member. The sliding member provides a fixing plate for being attached to the bottom of a table top and a sliding seat for being pivotally connected to a respective end of two lateral sides of an upper and lower connecting box sections provided with the lift member. Another end of said upper connecting box section is pivotally connected to a tray plate of the tray member and a lock part and a pair of retarding wheels provided with the lift member. The inclining member is disposed on the lock part and provides a stem handle. The sliding seat is capable of sliding in the fixing plate to move the upper and lower connecting box sections forward and backward. The upper and lower connecting box sections are capable rotating with respect to the sliding seat to perform upward and downward movements with the return spring. The stem handle of the inclining member is capable of rotating the eccentric collars. Hence, the tray plate with the keyboard thereon can move upward, downward, forward, backward and angularly.
