A camera including a body unit and a top cover unit configured to be mounted on the body unit. The body unit has a body section that defines a space within the camera. The camera also includes a component disposed on the top cover unit and a control unit disposed in the space defined within the camera. The control unit controls the component. The camera also includes a connection unit that electrically connects the component and the control unit. The connection unit is disposed proximately close to the space defined within the camera, thereby allowing the top cover unit to be removed from the body unit without disconnecting the component and the control unit and thereby allowing diagnostic operations to be performed within the camera.
