  • One mounting flange 94 is designed with an elongation for securing a tension spring 96, the other end of which is secured on a pin 97 mounted in the side wall 1, so that the blocking element 92 is biased counter-clockwise for abutment of the intermediate piece 95 against the arms 55-58.
  • Each of the actuation arms is, as shown for the arm 55, provided with two notches 98 and 99 for accommodating the intermediate piece 95 in the depressed position and the starting position, respectively, for the button.
  • FIG. 7 The co-operation between an actuation arm and the coupling 45 is illustrated in greater detail in FIG. 7 for the arm 55 which is shown in dotted lines in its depressed position where the terminal end of the arm shaped with a catch 100 is inserted into the path of movement for the associated cam 74 on the ball holder 54 and thereby prevents rotation of the ball holder, so that the coupling is released. ln this position the intermediate piece 95 on the blocking element 92 is situated in the notch 98. ln the starting position, push-button and actuation arm take up the position shown in solid lines, in which the catch 100 is removed from the coupling and the intermediate piece 95 is situated in the notch 99.
  • ink is for instance to be supplied in the full width of the duplicator, which takes place by depressing the push-button 36 located opposite the indication 40 corresponding hereto on the top plate 5, whereby the actuation arm 55 connected to the push-button 36 is inserted into the path of movement for the cam 74 on the ball holder 54 in the controllable coupling 45.

  • the button 9 may be depressed for actuating the above-mentioned ink pump to produce a single ink stroke through the ink supply hose 8 and the ink tube 6 to the total number of ink discharge apertures 11.
  • the pushbutton 38 corresponding hereto is depressed, whereby the actuation arm 57 with the edge located between the notches 98 and 99 forces the pivotable blocking element 92 out of the notch 98 in the already depressed push-button 55 against the bias from the spring 96, whereby the push-button 36 due to the bias from the compression spring 80 is returned to its starting position, so that the actuation arm 55 is removed from the coupling 45 and the coupling disc 46 is again coupled to the gear wheel 50.
  • the actuation arm 57 is, however, guided into the path of movement for the cam 76 on the ball holder 54, so that the rotation of the ball holder is stopped again when the cam 76 abuts against the arm 57, whereby the coupling is again released.
  • the turning of the zone adjustment tube 13 caused by the depression of the push-button 38 is thus limited to an angle corresponding to the angular distance between the cams 74 and 76 of the ball holder 28, that is to say 180.

If for instance the push-button 39 is depressed, the downwardly projecting part 88 will act on the member 88 by means ofits guiding pins. The actuation arm 58 will be carried along and the catch on the actuation arm 58 will be guided into the path of movement for the cam 78 in the coupling 45, in the way shown in FIG. 7. However, on the last part ofthe movement pin 108 secured on the extension 88' will actuate the common bar 101 to operate the ink pump for producing a single ink stroke.
