    Abstract: A projection optical system (10) is an optical system that projects from a first image plane (5) on a reducing side to a second image plane (6) on an enlargement side. The projection optical system (10) includes a first optical system (11) that includes a plurality of lenses and forms a first intermediate image (51) formed inside the first optical system (11) by light incident from the reducing side into a second intermediate image (52) on the enlargement side of the first optical system (11); a second optical system (12) that includes a first reflective surface (M1) with positive refractive power which is positioned further to the enlargement side than the second intermediate image (52); and a glass block (30) that is disposed between the first optical system (11) and the first reflective surface (M1), the glass block (30) passing light rays from the first optical system (11) to the second intermediate image (52).

    Abstract: The present invention relates to a device for preventing an expensive electronic camera from being stolen, and more particularly to a device for preventing a camera from being stolen which covers the lens module separation button of the camera body so as to prevent the lens module from being separated from the body without permission, and, if a thief attempts to steal the camera by separating the cover or a mounting unit, or cutting or separating a cable from an alarm, makes the alarm generate an alarm sound or a flickering light to warn him off and to notify the owner of the camera. The device for preventing a camera from being stolen according to the present invention includes: a cover for covering a lens module separation button enabling a lens module to be separated from a camera body; a mounting unit for mounting the cover to the camera body; and a sensor provided in the mounting unit for sensing a separation of the mounting unit.

    Abstract: A discharge lamp driving device includes a discharge lamp driving unit configured to supply driving current to a discharge lamp provided with a first electrode and a second electrode, and a controller configured to control the discharge lamp driving unit. The driving current includes a first AC period and a second AC period in which an AC current is supplied. The first AC period includes a plurality of consecutive first unit driving periods each of which is formed of a first polarity period and a second polarity period, a length of the first polarity period being larger than a length of the second polarity period. The second AC period includes a plurality of consecutive second unit driving periods each of which is formed of the first polarity period and the second polarity period, the length of the second polarity period being larger than the length of the first polarity period.
