An image capturing apparatus includes a pop-up flash. Pop-up flash includes a flash housing configured for receiving a flash therein, a drive lever and a locking lever. Flash housing is pivoted on image capturing apparatus, and moves between a first position and a second position relative to image capturing apparatus. Flash housing includes at least one positioning hole. Drive lever moves between a third position and a fourth position relative to image capturing apparatus. Locking lever abuts against drive lever. At least one locking protrusion perpendicularly extends upward from a longitudinal side thereof. When drive lever is at third position, at least one locking protrusion engages with at least one positioning hole to lock flash housing at first position; while when drive lever moves from third position to fourth position, flash housing is released to second position after at least one positioning hole separated from at least one locking protrusion.
