Appeal No. 96-1893
Application 08/073,416
canceled.
Appellants' invention relates to a magnetic tape recorder
with a slide chassis and a main chassis. More particularly,
as described on page 5 et seq. of the specification, Figure 1
shows a main chassis 6 and a slide chassis 7 with many through
holes to decrease the weight. Such a lightweight slide
chassis is easily subjected to deformations (see arrows 402
and 403 in Figure 6) during times when the pinch roller 41
(Figures 2 and 4) is pressed securely against the capstan
shaft 4. To avoid deformation, a positioning assistance
member 82 (as shown in Figures 10 and 11) is arranged on the
main chassis 6 to cooperate with a positioning member 8 to
limit the distance between the main chassis 6 and the slide
chassis 7 due to the force of the pinch roller 41 against the
capstan shaft 4.
Representative independent claim 12 is reproduced as
follows:
12. A magnetic recorder in which magnetic signals are
transmitted between a magnetic head device and a magnetic
tape, comprising:
a capstan shaft for driving the magnetic tape when the
magnetic tape is pressed against the capstan shaft, so that
