Abstract
PURPOSE: To drive the mirror of the camera surely with a simple mechanism by transmitting the revolutions of a motor to a ratchet gear and ending the rise of the mirror when the ratchet gear and ring arm assume a dead point.
CONSTITUTION: When a release signal is applied to the camera, a motor 1 begins to revolve and its revolutions are transmitted via reduction gear train 4 to a revolving trigger charging gear 5. The revolutions of the gear 5 are transmitted to a ratchet gear 10 which in turn pushes a link arm 11, thereby force turning a mirror drive lever 15 clockwise. When the mirror 28 reaches the ascending position, an arm 11 assumes a dead point with respect to the ratchet 10 and therefore the mirror 28 maintains the ascending position and the lens the stopping-down position. Since with this constitution the relations of the ratchet gear and link are used, the ascending and descending of the mirror may be surely accomplished through forward and backward revolutions of the motor with the simple mechanism.
