Claims

[Claims for Utility Model Registration] 1. A twin-lens reflex camera with a built-in multiple exposure mechanism, characterized by including the following mechanisms: - Main body; a notch into which each exposure pushbutton is inserted, a square notch through which a holder for controlling film winding can be extended outward, and a shaft into which a shutter brake plate and a film winding zero return control plate are fitted; A step shaft for fitting the spring and brake plate, a bearing for receiving the shaft, and a fixing screw hole for fixing the shutter pedestal and shutter switch are provided. - Shutter brake plate: It is equipped with a step shaft that generates the push rod and push pull action of the exposure push button, a hook, a shaft rod, and a shutter rod. - Brake plate: A V-shaped notch and a notch are provided to create a catching action on the shaft of the shutter brake plate, and a recessed edge, tip, convex point, and extension plate are separately provided. - Shaft: Provide a groove to create a braking action with the convex point of the brake plate. A shaft rod is provided to control the rotation of the film number display button, which provides a gap for the shaft rotation so that it can be displaced with the hook portion of the shutter brake plate. - a spring; one end is located in the brake plate extension and the other end is located in the step axis of the shutter brake plate, thereby driving and displacing the shutter brake plate; - The number display button is fitted into a convex rod on the film rewind zero return control board, and is connected to the control board using the force of a spring. - The shaft hole of the film winding control plate is fitted into the convex rod of the main body, and when the fixed shaft separates from the pressing part of the recessed edge of the brake plate, the slope pushes up the step shaft of the shutter brake plate and starts operating. - Wind the film using the knob. - Two convex rods are installed on the shutter pedestal to limit the operating range of the push-up shaft of the shutter brake plate.
A thin shutter plate is provided to create an exposure effect by the action of the push-up shaft. - Install a push seat on the shutter switch to press the brake plate extension. 2. In a twin-lens reflex camera equipped with the multiple exposure mechanism as stated in Claim 1 of the Utility Model Registration Claim, when the exposure pushbutton is pressed and the shutter brake plate is activated, the pushbutton is returned to its original position by a spring. Camera featuring a return.
