Abstract
A driving force transmission switching apparatus for a camera in accordance with the present invention includes: a drive source that generates a driving force; a worm gear that receives the driving force to rotate; a driving force transmission gear device that includes a driving gear and meshes the driving gear with the worm gear to move the driving gear in parallel to an axial direction of the worm gear as the worm gear rotates so as to shift the driving gear to a plurality of transmission positions for applying a driving force of the drive source and a non-transmission position for not applying the driving force of the drive source; a plurality of driven gears which are disposed in positions for meshing with the driving gear, respectively corresponding to the plural transmission positions where the driving gear is to be set, and which receive a driving force of the drive source via the driving gear; and a position control device for conducting control by meshing the driving force transmission gear device with the worm gear to move the driving force transmission gear device in parallel to an axial direction of the worm gear as the worm gear rotates so as to shift the driving force transmission gear device to a plurality of transmission positions for applying the driving force of the drive source and a non-transmission position for not applying the driving force of the drive source.
