摘要:
A connection portion (13) of an FFC (12) to be preliminarily arranged on a roof trim (10) is weld-fixed to cable connecting portions (25a, 26a) of a bus bar (25) and a spring terminal (26) of a room lamp (20). Simultaneously with the arrangement of the FFC (12) on a vehicle-body-panel-side portion of the roof trim, the room lamp (20) is mounted in the lamp mounting window.

A first retainer engages with an exterior side of an interior wall member to retain a lamp unit on an interior side of the interior wall member. A second retainer engages with an exterior side of a panel body to retain the interior wall member, on which the lamp unit is mounted, on an interior side of the panel body. The second retainer includes a flexible arm having a free end portion which is flexible in a first direction parallel with the panel body and a second direction perpendicular to the panel body. The free end portion is abutted against the exterior side of the panel body when the interior wall member is mounted on the panel body. A regulator prevents the free end portion of the flexible arm from being flexed more than a predetermined amount in the second direction when the flexible arm is not flexed in the first direction.

An imaging apparatus analyzes a periodic pattern of a Moiré due to Talbot interference by the Fourier transform method and forms an image. The imaging apparatus includes a first grating having a structure that transmits light beams from a beam source to refract or diffract the light beams and forms a self image based on a first periodic pattern by the Talbot interference at a predetermined position; a second grating that absorbs part of the first periodic pattern and causes a Moiré to be generated based on a second periodic pattern when the second grating is arranged at a position at which the self image is formed. All cross sections of the Moiré with axes in differential directions of a wavefront for the analysis by the Fourier transform method have a two-dimensional periodic structure in which periods of patterns in the second periodic pattern are the same.
