Abstract
A single tray is used to collate the printed papers from a printer. The tray is moved to different positions to receive the printed papers. Thus, the printed papers are collated into different stacks. The movement of the tray can be linear or curvilinear. The circular movement can collate the printed papers into more than two stacks.
Claims2
A collator for a printer, the collator comprising:
- a tray for collecting papers exiting the printer, an end of the tray being pivotally installed in the printer;
- and
- an electromagnet attached to a first end of an arm, a second end of the arm being coupled to another end of the tray;
- wherein when the electromagnet is turned on and off, the electromagnet causes the tray to pivotally rotate back and forth along a curvilinear direction so that the tray is capable of collecting and collating the papers.

A collator for a printer, the collator comprising:
- a tray for collecting papers exiting the printer, an end of the tray being pivotally installed in the printer and collating the papers in at least two positions, the positions being separated from one another by an angular displacement;
- a spring attached to a first side of the tray, the spring providing a biasing force to the tray in a first direction;
- a motor attached to an eccentric cam;
- and
- a belt connecting the eccentric cam with a second side of the tray;
- wherein when the motor causes the cam to rotate to a first angle, the eccentricity of the cam causes the belt to pivot the tray against the bias of the spring from a first position to a second position, when the motor causes the cam to rotate to a second angle, the eccentricity of the cam allows the bias of the spring to return the tray to the first position, so that the tray is capable of collecting and collating the papers.
