Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a camera set for multiple photography that can perform trick photography and multiple photography, and in particular, relates to a camera set for multiple photography that can perform trick photography and multiple photography. Multiplexing that made shooting possible? @Regarding the shadow camera set.

[Background of the invention]

Traditionally, multiple shooting functions have been provided in single-lens reflex cameras that require multiple specifications, but in lens-shutter cameras, which are designed with compactness and economy as the top priority, the multiple shooting function is the king. For these reasons, a multiplex shooting function has not been incorporated. In other words, in a lens shutter camera, film winding and shutter charging can be performed at the same time or at the same time, making it possible to realize a compact, lightweight, and highly economical camera. This is because film winding and shutter f-jerking must be performed separately, which impairs the compactness and economic efficiency inherent in lens shutters and shutter cameras. In particular, a fully automatic lens shutter equipped with an autofocus mechanism.

If an attempt is made to provide a multi-photographing function to a standard camera, film winding, shutter, tar charge, and AF (autofocus mechanism) charging must all be performed separately, resulting in a significant increase in the cost of the camera. As a result, there was a risk that the original advantages of a lens shutter camera, such as compactness and economy, would be lost.

Therefore, in the past, there were no plans to realize a lens shutter camera capable of multiple shooting, and no accessories for lens shutter cameras necessary for multiple shooting had been devised.
