Device for securing the image position for multiple exposure of film
摘要:
The present invention provides a multiple exposure image position securing device for a camera having a housing, the device having a slide positioned on the housing, a rewind release button protruding from the housing adjacent the slide, a film transport mechanism located within the housing, a coupler located within the housing and coupled with the film transport mechanism, a lever mechanism extending between the rewind release button and the coupler, a catch lever selectively engaging the coupler, a pawl selectively engaging the film transport mechanism, and a winder positioned on the housing and coupled to the film transport mechanism. The present invention further provides a method of securing a multiple exposure image position in a camera having a disengaging device, having the steps of providing a slide and a rewind release button, actuating the rewind release button with the slide to actuate a coupler and disengage the coupler from a film transport mechanism, and rotating an eccentric spindle with the slide to (1) disengage a catch lever from the coupler and (2) pivot a retaining pawl attached to the eccentric spindle to engage the film transport mechanism to secure the image position.
