Abstract

The disclosure relates to a multi-functional printer. The multi-functional printer comprises an automatic document feeder member located in a scanner device and being movable between a unlifted position and a lifted-up position; a pen door located in a printer device and being movable between an open position and a closed position; and a link mechanism positioned between the automatic document feeder member and the pen door, such that when the automatic document feeder member is moved between, the unlifted position and the lifted-up position, the pen door moves with the automatic document feeder member to open or close the pen door.

Claims

1. A multi-functional printer, comprising:

an automatic document feeder member located in a scanner device and being movable between a unlifted position and a lifted-up position;

a pen door located in a printer device and being movable between an open position and a closed position; and

a link mechanism positioned between the automatic document feeder member and the pen door, such that when the automatic document feeder member is moved between the unfilled position and the lifted-up position, the pen door moves with the automatic document feeder member to open or close the pen door.

2. The multi-functional printer of claim 1, wherein the link mechanism includes:

an actuator positioned under the automatic document feeder member;

a return mechanism which is compressed to store energy when the automatic document feeder member is at the unlifted position and which activates the actuator with the stored energy when the automatic document feeder member is lifted from the unlifted position; and

a drive assembly connected to the actuator and the pen door.

3. The multi-functional printer of claim 2, wherein the actuator includes;

a lever;

an tipper guider for guiding the lever; and

a lower guider fixed to a base of the multi-functional printer,

the lever positioned under the automatic document feeder member and slidably housed in the lower guider at the lower end thereof.

4. The multi-functional printer of claim 3, wherein the lever includes a rack portion at the lower end thereof, and the drive assembly includes a gear assembly.

5. The multi-functional printer of claim 4, wherein the gear assembly includes an idler gear meshed with the rack portion and a driven gear which is meshed with the idler gear and drives the pen door.

6. The multi-functional printer of claim 3, wherein the upper guider and the lower guider are sleeves.

7. The multi-functional printer of claim 2, wherein the return mechanism is a spring.

8. The multi-functional printer of claim 2, wherein the return mechanism is a hydraulic cylinder.

9. The multi-functional printer of claim 2, wherein the actuator further includes a stopper member.

10. The multi-functional printer of claim 1, wherein the automatic document feeder member further includes a lock mechanism which holds the automatic document feeder member at the lifted-up position.
