Modulated light (image light) which has been modulated by passing through a liquid crystal display panel passes through an apical angle variable prism (so-called, a vari-angle prism) and then is enlarged and projected by a projection lens. The apical angle variable prism is configured to change the prism apical angle with, for example, an electromagnetic actuator. The microcomputer calculates a projection optical axis correction value based on hand shake detection signals from a sensor and controls the aforementioned actuator based on the correction value. With this control, shakes of projected images due to hand shakes are prevented.

A sliding mechanism used for an apparatus such as a portable device suppresses shaking between housing units in an opened state, closed state or on the way to opening/closing. A slide module is provided for opposed surfaces against a first housing unit (upper housing unit) and second housing unit (lower housing unit) to be slid. The slide module slidably supports the first and second housing units. Since the slide module has a slider and a fixing part that slidably supports the slider, it is structured that in case the first and second housing units are in an opened state, the slider is not exposed through the first and second housing units. Structure is included that compared with the first and second housing units in a closed state, in case in the opened state, a guide of the slider for the fixing part of the slide module is made wider.
