摘要： A winding stem (10) is connected to an inner end (11a) of a mainspring (11), and an outer end (11b) of the mainspring (11) is connected to a barrel drum (12). A braking plate (15) is placed inside a braking case (14), and the braking case (14) is filled with a fluid (16). An uneven joint portion (10b) is formed at the lower end of the winding stem (10), and is engaged with an uneven joint portion (15b) of the braking plate (15) placed in the braking case (14). By adopting the above configuration which can simplify the structure of the mainspring mechanism having the braking plate and which can reduce the number of components, the size and production cost of the mainspring mechanism can be reduced.

摘要： A light modulation device side lens group has different powers in the longitudinal direction and the lateral direction of a liquid crystal panel. Therefore, as the entire system of the optical projection system, the light modulation device side lens group has different magnification in the longitudinal and lateral directions. Therefore, it is possible to make the aspect ratio of an image of the liquid crystal panel different from the aspect ratio of an image projected on a screen. That is, conversion can be performed on an aspect ratio. At this time, a distance p between each focus or a diaphragm and the screen SC side end surface of the light modulation device side lens group satisfies the conditional expressions, so it is possible to achieve a predetermined or higher telecentricity in both states, that is, a first operating state and a second operating state.
