1 distance and then the hold-release means on the slave shifter is
2 actuated in the opposite direction to the above-mentioned first
3 actuation to hold the head to be set subsequently.

8 slidably fitted about the shafts 15 and also threadedly engaged with
9 the screw shaft 16, numeral 24 designates a slave shifter loosely fitted
10 about the respective shafts 15 and 16.” (Hirakawa, col. 5, ll. 3-7).
11 30. [I]f the piston rod 26 is extended, the slave shifter 24 would
12 advance relative to the master shifter 23 by a predetermined
13 distance represented by B in FIG. 7, while if the piston rod 26 is
14 contracted, the slave shifter 24 would be restored to the position
15 adjacent to the master shifter 23 as represented by double dot
16 chain lines in FIG. 7.

20 31. “In FIGS. 5 and 6, reference numeral 27 designates a pair of
21 arms pivotably mounted at the opposite ends of the slave shifter 24.”
22 (Hirakawa, col. 5, ll. 23-25).
23 32. Now the operation of the above-described positioning
24 apparatus will be explained with reference to FIGS. 11 and 14.
25 In case that the heads 3 - 6 and 3' - 6' are to be set at next
26 slitting positions or at next score line positions, a position
27 change signal is transmitted to the positioning apparatus. When
28 this signal is transmitted, the motor 22 is driven in the positive
29 direction, so that the slave shifters 24 and 24' located at the
30 positions shown in FIG. 8 (It is to be noted that in FIG. 11 the
31 positions of the slave shifters 24 and 24' are represented as
32 replaced by the contact plates 29 and 29', respectively.) move
33 towards a storage section (in the rightward direction), and
34 eventually the slave shifter 24 would actuate a limit switch 30
