    • A portable telephone device with incorporated projector 10 starts projection by a projection module 6 when a relative angle θ is set to a projection attitude of 80° and three seconds elapses. If a setting is made for performing vibration correction processing, then a camera unit 200 is commanded to start image-capturing or photographing frame pictures continuously. The portable telephone device with incorporated projector 10 calculates six movement vectors by comparing pictures between successive frames photographed by an image sensor. Along with deciding upon “hand tremor” based upon the movement vectors which are calculated, moreover a representative vector is calculated. The portable telephone device with incorporated projector 10 further creates picture shift information for canceling the representative vector, and, if “hand tremor” has been decided upon, suppresses vibration or wobbling of the contents projected by the projector module using the picture shift information.

    • A hollow portion is provided on the core of an inner shaft (2) to form an oil feed port (3), a plurality of oil feed holes (4) which are connected with both of the outer peripheral face of the inner shaft (2) within a range (L) of the bearing surface of the inner shaft (2) and the oil feed port (3) are radially provided in a line , and axial oil grooves (5) each of which includes an inner shaft surface side opening portion (4a) of the oil feed hole (4) are provided on the outer peripheral face of the inner shaft to form a contra-rotating bearing device for a contra-rotating propeller which causes the inner shaft (2) and an outer shaft (2) to contra-rotate mutually. In place of the oil grooves, a plurality of concave-convex portions may be formed in the axial direction of a contra-rotating bearing on the inner peripheral face of the bearing and circular portions may be provided on both axial ends of the concavo-convex portions to form the contra-rotating bearing device for a contra-rotating propeller. Thus, a sufficient oil film is formed on the bearing surface of the contra-rotating bearing in an area where the inner shaft and the outer shaft rotate in mutually opposite directions at almost equal speeds so that an excellent bearing function can be obtained.
