Abstract
A compact sheet carrying device comprises a tray, a first supporting arm and a second supporting arm. The tray supports a first portion of a sheet. The first supporting arm is pivotally connected to the tray at one end having a first toothed portion. The second supporting arm is pivotally connected to the tray at one end having a second toothed portion. The two toothed portions mesh with each other. The two supporting arms are concurrently in a deployed state or a retracted state. In the deployed state, the two supporting arms support a second portion of the sheet. A document processing apparatus using such sheet carrying device is also provided.
Claims15
A compact sheet carrying device, comprising:
- a tray for supporting a first portion of a sheet;
- a first supporting arm pivotally connected to the tray at one end having a first toothed portion;
- a second supporting arm pivotally connected to the tray at one end having a second toothed portion, wherein the first toothed portion and the second toothed portion mesh with each other, the two supporting arms are concurrently in a deployed state or a retracted state, and the two supporting arms support a second portion of the sheet in the deployed state;
- and
- a resilient fixing projection disposed on an outer edge of the one end of the first supporting arm, wherein the resilient fixing projection is engaged with a positioning structure of the tray to position the first supporting arm.
A compact sheet carrying device, comprising:
- a tray for supporting a first portion of a sheet;
- a first supporting arm pivotally connected to the tray at one end having a first toothed portion;
- a second supporting arm pivotally connected to the tray at one end having a second toothed portion, wherein the first toothed portion and the second toothed portion mesh with each other, the two supporting arms are concurrently in a deployed state or a retracted state, and the two supporting arms support a second portion of the sheet in the deployed state;
- a first extension arm having a connection end rotatably connected to a distal end of the first supporting arm;
- and
- a second extension arm having a connection end rotatably connected to a distal end of the second supporting arm, wherein distal end portions of the first and second extension arms are rotatably connected together, and the first and second extension arms support a third portion of the sheet in a deployed state of the two supporting arms.
