A method of fabricating an integrated circuit having an n-channel and a p-channel transistor is provided. Each scent channel includes a scent material supply and a scent activation system that selectively activates predetermined portions of the scent material supply. The transferring unit includes a projection at a rear end portion thereof and the casing includes a restricting portion that is arranged lower than the projection of the transferring unit midway through mounting and is engaged with the projection at completion of the mounting of the transferring unit. The device includes a driver for the user-defined clipping in the object space to perform dual mode user-defined clipping in object space when a lighting function is disabled and in eye space when the lighting function is enabled.
