Various embodiments of the present invention relate to an electronic instrument
holding device and, more particularly, to an electronic instrument holding device
having a circuit board. The present invention holds an electronic instrument at
a predetermined angle and connects an input device to the electronic instrument
so that a user may input information into the electronic instrument with a comfortable
viewing angle. A circuit board may also be equipped on the electronic instrument
holding device to replace or enhance the board disposed inside the input device
so that manufacturing and assembling the input device are accelerated.
