Abstract

This disclosure relates to sheet or paper handling in a copier or printing machine, and more particularly to an upper paper guide 10 of a sheet transport assembly in such a copier or printer. Ordinarily, such an upper paper guide is held in position by a spring force. However, due to changing machine conditions (i.e. vibration), the entire transport can shake during machine operation. Such shaking can cause paper handling nip rollers 12 attached to the transport assembly to lose their paper gripping and feeding force.

LATCH & RELEASE MECHANISM FOR PAPER TRANSPORT

(Cont'd)

This disclosure relates to sheet or paper handling in a copier or printing machine, and more particularly to an upper paper guide 10 of a sheet transport assembly in such a copier or printer. Ordinarily, such an upper paper guide is held in position by a spring force. However, due to changing machine conditions (i.e. vibration), the entire transport can shake during machine operation. Such shaking can cause paper handling nip rollers 12 attached to the transport assembly to lose their paper gripping and feeding force.

In accordance with this disclosure as illustrated in the drawing, a pair of spring loaded translation rods 20A, 20B which each extend horizontally into a frame-mounted stop block 22, are used to lock the paper guide 10 into a fixed operating location. To release the paper guide, a central release handle 24 is pivoted upwards, for example, manually. This action forces the rotation of two pivot arms 26, which, in turn, push on blocks 30 mounted to the other ends of the rods 20A, 20B. The result is a translation of the rods 20A, 20B which pul...
