Appeal No. 1999-1488
Application 08/630,332
Moreover, the sheet sensors 26 of Yamamoto are used
to activate the drive rollers 23 to the printer 30 when a
sheet P is detected (col. 4, lines 48 to 64). The examiner
contends on page 4 of the answer that this disclosure would
have made it obvious to place a sheet sensor downstream of
Lang's feed roller 24 to control drawer lock 18, but we do not
agree, because in Yamamoto the sensors 26 control a device
(rollers 23) downstream, rather than upstream, from them.
Also, in the examiner's proposed modification of Lang, the
sensor would control a device (lock 18) upstream from the
sensor; such a modification of Lang would not have been
obvious because in Lang's device the tray (drawer) is intended
to be locked when the feeder 24 starts, not thereafter, as it
would be if sensors were placed after the feeder.
