Photographic binocular telescope with lidded battery chamber

摘要

A binocular telescope 10 with a photographing function comprises a casing having a front wall and a battery chamber 45 having an opening with a lid 46 in the front wall, with the battery chamber being formed in the casing or body located outside the telescopic optical system 14R, 14L, 16 of the device. As shown, battery chamber 45 is positioned to one side of the telescopic optical system. The battery chamber 45 may house a dummy battery (DB, Figure 6), i.e. a terminal in the shape of a battery, that supplies power from an external power source, instead of a conventional battery; the lid may have a notch 52 through a power supply card (50, Figure 6) passes. Alternatively, the battery chamber has a separate power input terminal (54, Figure 7), a power lead passing through an access hole (56, Figure 7) in the battery chamber lid to connect to the input terminal.
