A structure for assembly of a binocular telescope with a photographing function,
comprises a lower frame, an upper frame, and an engaging mechanism. A pair of telescopic
optical systems is mounted on the lower frame. A photographing unit is mounted
on the upper frame. A first part of the engaging mechanism is provided on the lower
frame. A second part of the engaging mechanism is provided on the upper frame.
The first part and the second part are connected by assembling the upper frame
onto the lower frame in such a manner that the photographing unit is placed between
the pair of telescopic optical systems.
