An imaging apparatus has: a white balance control circuit for detecting an achromatic portion of an image of an object and controlling gains of the chrominance; an object distance detecting circuit for detecting a distance to the object; and a zoom value detecting circuit for detecting a zoom value of the optical system. A plurality of diagonal crosses which are composed of an upper partial cross and a lower partial cross can be arranged between the longitudinal members. The combiner has a reasonably large degree of isolation between the output ports. The conductive bond contacts and electrically connects the leads. Movement of the flaps can be by application of a voltage to the flaps, followed by removal of the voltage to return the flaps to their original position. Advancing the punch and the hollow tube through the die such that a portion of the hollow tube is extruded into the second portion of the die and the outer surface of the hollow tube conforms to the inner surface of the die to thereby form the trailer receiver tube.
