Abstract
An apparatus for changing the direction of conveying paper in which paper is stopped by the operation of driving roller pairs in conjunction with idle roller pairs. The respective driving and idle roller pairs are urged against one another by the operation of a solenoid or the like. In order to move the paper, a clutch is engaged to rotatably operate the driving pairs.
Claims4
An apparatus for changing the direction of paper of varying sizes and thicknesses conveyed therethrough comprising:
- a lower guide plate;
- first driving rollers for conveying the paper in a first direction so as to pull the paper into said lower guide plate;
- second driving rollers for conveying the paper in a second direction perpendicular to the first direction so as to send out the paper from said lower guide plate;
- first idle rollers selectively movable into and out of abutting engagement with said first driving rollers to selectively hold the paper between said first idle rollers and said first driving rollers;
- second idle rollers selectively movable into and out of abutting engagement with said second driving rollers to selectively hold the paper between said second idle rollers and said driving rollers;
- first means for moving said first idle rollers into engagement with said first driving rollers to convey the paper in said first direction;
- second means for moving said second idle rollers into engagement with said second driving rollers when said first idle rollers are out of engagement with said first driving rollers to convey the paper in said second direction;
- a driving source for generating a driving force;
- and
- a clutch means for selectively communicating said driving force to said first and second driving rollers to rotate the first and second driving rollers simultaneously.

A process for changing the direction of paper of varying sizes and thicknesses in a paper conveying apparatus, comprising the steps of:
- providing a first driving roller arranged for rotation in a first direction;
- providing a second driving roller arranged for rotation in a second direction, said second direction different from said first direction;
- providing a first idle roller and a second idle roller for movement into and out of engagement with said first driving roller and said second driving roller, respectively;
- abutting said first idle roller against said first driving roller to hold the paper between said first driving roller and said first idle roller and maintaining said second idle roller separate from said second driving roller;
- rotating said first and second driving rollers to transfer the paper in said first direction;
- stopping the transfer of said paper in said first direction by the steps of stopping the rotating of said first and second driving rollers and separating said first idle roller from said first driving roller;
- abutting said second idle roller against said second driving roller to hold the paper between said second driving roller and said second idle roller and maintaining said first idle roller separate from said first driving roller;
- and
- rotating said first and second driving rollers to transfer the paper in said second direction.
