An image capturing apparatus includes an image sensor configured to operate in a line-sequential manner and a shutter device operatively coupled to the image sensor. After the seat is moved in the forward direction with the seat back being turned forward, the link mechanism makes the lock mechanism inoperative so that the seat can be moved in a rearward direction regardless of a state of the seat back being positioned in the forward. The field effect transistor is formed in a second region of the substrate.
