摘要： An electronic device has a first cabinet and a second cabinet. The second cabinet has a locking module including a hook, an operation member and a linking mechanism. The hook is formed at a position near a top end of the second cabinet around the center in the lateral direction in opened state, and is engaged with the first cabinet to lock the second cabinet in the closed state. The operation member disengages the hook from the first cabinet in response to operation. The linking mechanism links the operation to movement of disengaging the hook. The second cabinet further has a board mounted with a camera module having an image taking lens and an imaging device and a signal processing circuit for the camera module. The board is disposed at such a position that a portion in which the signal processing circuit is mounted overlaps with the linking mechanism.
