Paper tray mechanism
View Patent ↗A paper tray mechanism that is applicable to machines with paper trays, such as printers, scanners, copiers, fax machines, all-in-one multifunction center and the like, comprises an input paper tray, an output paper tray, where both trays are movable and attached to the machine at sides, and an interconnecting mechanism therein between the two trays. When one paper tray is moved by the user, due to the interconnecting mechanism therein between, another paper tray will automatically move simultaneously. Therefore, this invention provides a paper mechanism that only needs one simple and easy step to have both paper trays unfolded/folded and unstashed/stashed so that some spaces are saved for other usage and machine is compact enough to be repacked into the original box.
1. A paper tray mechanism to be used inside a machine having paper trays, comprising:
an input paper tray, being movable and attaching inside said machine;
an output paper tray, being movable and attaching inside said machine relative to said input paper tray; and
a linkage, being inside said machine between said output paper tray and input paper tray, and having one end attaching to said input paper tray and another end attaching to said output paper tray so that both the input and output paper trays move simultaneously.
2. The paper tray mechanism as claimed in claim 1 , wherein said machine has a sliding track inside along which said input paper tray can slide.
3. The paper tray mechanism as claimed in claim 1 , wherein said machine has a sliding track inside along which said output paper tray can slide.
4. The paper tray mechanism as claimed in claim 1 , wherein said linkage is suspended inside said machine.
5. A paper tray mechanism to be used inside a machine having paper trays, comprising:
an input paper tray, being movable and pivotally attaching inside said machine;
an output paper tray, being linearly movable inside said machine relative to said input paper tray; and
an interconnecting mechanism, being inside said machine between said output paper tray and input paper tray, including a first linkage and a second linkage pivotally pinned to each other, one end of said first linkage being fixed with said input paper tray and one end of said second linkage being pivotally pinned to said output paper tray, so that both the input and output paper trays move simultaneously.
6. The paper tray mechanism as claimed in claim 5 , wherein said machine has a sliding track inside along which said output paper tray can slide.
7. The paper tray mechanism as claimed in claim 5 , wherein said second linkage is suspended inside said machine.
8. A paper tray mechanism to be used inside a machine having paper trays, comprising:
an input paper tray, being linearly movable inside said machine;
an output paper tray, being movable and pivotally attaching inside said machine relative to said input paper tray; and
an interconnecting mechanism, being inside said machine between said output paper tray and input paper tray, including a first linkage and a second linkage pivotally pinned to each other, one end of said first linkage being pivotally pinned to said input paper tray and one end of said second linkage being fixed with said output paper tray, so that both the input and output paper trays move simultaneously.
9. The paper tray mechanism as claimed in claim 8 , wherein said machine has a sliding track inside along which said input paper tray can slide.
10. The paper tray mechanism as claimed in claim 8 , wherein said first linkage is suspended inside said machine.
11. A paper tray mechanism to be used inside a machine having paper trays, comprising:
an input paper tray, being movable and pivotally attaching inside said machine;
an output paper tray, being movable and pivotally attaching inside said machine relative to said input paper tray; and
an interconnecting mechanism, being inside said machine between said output paper tray and input paper tray, including a first linkage and a second linkage pivotally pinned to each other, one end of said first linkage being fixed with said input paper tray and one end of said second linkage being fixed with said output paper tray, so that both the input and output paper trays move simultaneously.
