Abstract

In an electrophotographic printing machine, it is frequently necessary to register the copy sheet as it advances along the sheet path. As shown in Figure 1, the copy sheet moves in the direction of arrow 10 until it engages guide 12. Guide 12 is pivoted into the copy sheet path by spring 14. At the appropriate time coil 16 is energized overcoming the force of spring 14 to pivot guide 12 in a downwardly direction away from the sheet path. This permits the copy sheet to continue to move in the direction of arrow 10.

In an electrophotographic printing machine, it is frequently necessary to register the copy sheet as it advances along the sheet path. As shown in Figure 1, the copy sheet moves in the direction of arrow 10 until it engages guide 12. Guide 12 is pivoted into the copy sheet path by spring 14. At the appropriate time coil 16 is energized overcoming the force of spring 14 to pivot guide 12 in a downwardly direction away from the sheet path. This permits the copy sheet to continue to move in the direction of arrow 10.

An alternate embodiment to the foregoing is depicted in Figure 2, Rather than employing a spring a second electromagnet 18 is utilized. Actuation of coil 18 and de~activationof coil 16 pivot guide 12 into the sheet path. When coil 18 is de~ energized and coil 16 is energized guide 12 pivots away from the sheet path. In this way, the sheet continues along the path of movement as indicated by arrow 10,
