1 SWI sets the delay in inches from the edge of a sheet 30 being detected to
2 the start of a line of perforations. Switch SWII sets the distance in inches
3 (time) from the start to the stop of a line of perforations. Switch SWIII sets
4 the overall size of the full length of the sheet 30 from the time it is detected
5 through its full length, so the apparatus only cycles once per sheet (col. 4, ll.
6 15-24). A sheet detector 41 is provided to detect the edge of a sheet fed into
7 the device.
8 Moll emphasizes the desirability of a perforating apparatus which
9 provides a line of perforations on a sheet of paper at locations and of lengths
10 that can be varied easily (col. 2, ll. 13-19 and 43-46).
11 The Examiner’s first theory of unpatentability is that it would have
12 been obvious to have modified Moll by providing a bar code reader and bar
13 codes on all sheets, as taught by Hayamizu, to automate the process of
14 setting when the perforator is activated, thus reducing the work of the
15 operator (Answer 5).
16 The Examiner’s second theory of unpatentability is that it would have
17 been obvious to have modified Hayamizu by making the blades perforating
18 blades, as taught by Moll, in order to keep all the products (drawing sheets)
19 together for later disassembling (Answer 5-6).
20 Carter discloses a copying machine 5 provided with a top adjustable
21 slitter/perforator 50 for on-line slitting and perforating of copy sheets as the
22 sheets are fed to top output tray 44 (col. 2, ll. 44-47). The slitter/perforator
23 unit is adjustable while paper is moving through it to permit different
