A mirror support mechanism includes three first supporting members and three second supporting members. Each first supporting member includes a mirror supporting portion that is in contact with and support a corresponding one of three supported surfaces provided on the supported portion with rotational symmetry of 120 degrees around an optical axis, and two first beam portions connected to both sides of the mirror supporting portion. Each second supporting member includes a supporting portion to which ends of two first beam portions adjacent to each other are connected, the ends being not connected to the mirror supporting portion, and two second beam portions connected to both sides of the supporting portion, an end of the second beam portion not connected to the supporting portion being supported by a structure member provided on the rear side of the reflecting mirror.

Mirror support mechanism and optical device

In a magnetic random access memory circuit, the potential of all sense lines to are equalized, and the potential of all not-selected word lines are equalized and the selected word line is grounded so that a previously charged capacitor is discharged by a current path passing from the capacitor through a MOS transistor maintaining the potential of the sense line at a constant voltage lower than a break voltage, through the selected sense line , through the selected magneto-resistive element and through the selected word line . Thus, a voltage applied to the magneto-resistive element is maintained at a level smaller than a voltage breaking the magneto-resistive elements or a voltage remarkably deteriorating the characteristics of the magneto-resistive elements because of a biasing effect when the tunnel magneto-resistive element is used, and on the other hand, a high precise and high speed reading can be realized.
