change in positional relationship between the main chassis and
the slide chassis in the at least one direction." (answer at
page 11). The Examiner further states that although it is
true that Tsuchida achieves engagement whether or not the
magnetic tape is pressed against the capstan shaft by the
pinch roller, when the tape is held by such a force, it also
restrains a change in positional relationship (answer at page
13).
While we appreciate the Examiner's theory of pinch roller
force to restrain a change in positional relationship between
the main and slide chassis, a thorough review of Tsuchida
shows no support for this theory. Figures 20 and 21 show that
sliding movement between the main and slide chassis is
accomplished by
worm gear 35 and rack 36, and completion of loading is
detected by sensor switch 130 (note also column 9, lines 1-
12). Once loading is terminated, worm gear 35 in conjunction
with rack 36 would restrain any change in the positional
relationship. Since Tsuchida is silent as to the pinch roller
