cassette half 1b at the side of the reference guide 8 against
a reference surface 11b of the position adjusting block 10 and
the inner side surface of the reference guide 8 and thereby
adjusts the position of the lower cassette half 1b.
Mizuta teaches that as shown in Figure 3, after the
positions of the lower cassette halves 1a and 1b have been
adjusted in the manner described above, the whole perforating
means 4 moves down. After the perforating process has been
finished, the perforating means 4 moves up and returns to its
original position. At the same time, the position adjusting
push members 3a and 3b move away from the lower cassette
halves 1a and 1b, and the position adjusting block 10 moves
down. In this manner, the lower cassette halves 1a and 1b are
released from the position adjusting force. Thereafter, the
lower cassette halves 1a and 1b are again conveyed by the
intermittent feed means together with the other lower cassette
halves to the downstream side.
The appellants argue (brief, pp. 3-6) that Lachaussee and
Mizuta both fail to teach, either expressly or by the doctrine
