frame 9 at a location which does not overlap the fixing
instrument 5. The lead wires 15 as well as other electric
wires 17 are laid within the guide frame 9. A lamp cover 14
has a side wall portion which is confronted with the
balustrade panel 4 with a gap left therebetween. Saito
teaches (column 4, line 63, to column 5, line 16) that
Moreover, according to the invention, recirculation
of cooling air makes it possible to prevent a rise in
temperature due to heat generation of the rod-like
fluorescent lamp 18. Heat is generated by turning-on the
rod-like fluorescent lamp 18, and a rise in temperature
is remarkable, in particular, at the sections adjacent
the sockets 13. As described previously, however, since
each of the non-contact sections h is utilized to mount a
1
corresponding one of the sockets 13, a non-contact
section of the size of h still remains at the non-contact
2
section h , even if the thicknesses of the respective
1
brackets 11A and 11B are taken away from the non-contact
section h . Thus, air can freely communicate with the
1
interior of the main deck 8 through the non-contact
section h or the non-contact section h . Moreover, since1 2
the lamp cover 14 and the main deck 8 are maintained out
of contact with the balustrade panel 4, air can freely
flow as indicated by the broken lines in FIG. 3 so that
heat can sufficiently be radiated. As a result, such
inconveniences as heat damage and the like of the lamp
cover 14 due to a rise in temperature within the main
deck 8 can be eliminated.
The examiner's position (answer, page 4) is that the heat
generated by Saito's lights 18 will inherently meet the
