A torsion coil spring spring-biases a rotary plate in such direction that a display unit may be rotated around rotary shafts, so as to rise from a horizontal position. An extension spring spring-biases the display unit, so that the display unit may be changed from an anti-rising direction to a rising direction while the display unit is being rotated, whereby a driving torque may become substantially constant against the weight of the display unit. One end of the extension spring is engaged with the rotary plate and the other end thereof is engaged with an engagement pin disposed at a position displaced from the center of the rotary shaft of the display unit. The length of the extension spring becomes longest while the rotary plate is being tilted and rotated. Thus, the electronic equipment tilting and rotating apparatus can tilt and rotate the display unit with application of a necessary and minimum driving torque.
