Multi-function printer with a locking device and operational method thereof
First Claim
1. A locking device, disposed in a multi-function printer, the multi-function printer comprising at least an auto document feeder (ADF), a scanner and a main body, the scanner being positioned on the main body and pivotally connected to the main body, the ADF being disposed on the scanner and pivotally connected to the scanner, the locking device, comprising:
- a trigger piece, fixed to the ADF, and protruded into the scanner;
a wedging piece, disposed in the scanner and having one end protruding under the scanner;
an actuating piece, disposed in the scanner; and
a join piece, disposed in the scanner, the join piece having a first end connected to the actuating piece and a second end positioned close to the trigger piece;
wherein when the ADF is set onto the scanner and the scanner is set onto the main body, the trigger piece presses against the wedging piece and the actuating piece presses against the main body;
when the ADF is rotated relative to the scanner, the trigger piece is separated from the wedging piece along with the ADF such that the one end of the wedging piece is wedged with the main body and the scanner is locked to the main body;
when the scanner is rotated relative to the main body, the actuating piece is separated from the main body along with the scanner and the join piece is driven by the actuating piece to wedge with the trigger piece such that the scanner is locked to the ADF.

Abstract
A multi-function printer is provided. A trigger piece is fixed to the first module and stretched into a second module. A wedging piece is disposed in the second module and protruded from the second module. An actuating piece and a join piece are disposed in the second module. The actuating piece has a first end connected to the actuating piece and a second end positioned close to the trigger piece. When the three modules are stacked together, the trigger piece goes against the wedging piece and the actuating piece goes against a third module. When the first module is rotated, the trigger piece is separated from the wedging piece such that the wedging piece can be wedge with the third module. When the second module is rotated, the actuating piece drives the joint piece to wedge with the trigger piece.

1. A locking device, disposed in a multi-function printer, the multi-function printer comprising at least an auto document feeder (ADF), a scanner and a main body, the scanner being positioned on the main body and pivotally connected to the main body, the ADF being disposed on the scanner and pivotally connected to the scanner, the locking device, comprising:
-
a trigger piece, fixed to the ADF, and protruded into the scanner; a wedging piece, disposed in the scanner and having one end protruding under the scanner; an actuating piece, disposed in the scanner; and a join piece, disposed in the scanner, the join piece having a first end connected to the actuating piece and a second end positioned close to the trigger piece; wherein when the ADF is set onto the scanner and the scanner is set onto the main body, the trigger piece presses against the wedging piece and the actuating piece presses against the main body; when the ADF is rotated relative to the scanner, the trigger piece is separated from the wedging piece along with the ADF such that the one end of the wedging piece is wedged with the main body and the scanner is locked to the main body; when the scanner is rotated relative to the main body, the actuating piece is separated from the main body along with the scanner and the join piece is driven by the actuating piece to wedge with the trigger piece such that the scanner is locked to the ADF. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A multi-function printer, comprising:
-
a first module; a second module, disposed under the first module and pivotally connected to the first module; a trigger piece, fixed to the first module and protruded into the second module; a wedging piece, disposed in the second module and having one end protruding under the second module; an actuating piece, disposed in the second module; a join piece, disposed in the second module, the join piece having a first end connected to the actuating piece and a second end positioned close to the trigger piece; and a third module, disposed under the second module, and pivotally connected to the second module; wherein when the first module is set onto the second module and the second module is set onto the third module, the trigger piece presses against the wedging piece and the actuating piece presses against the third module; when the first module is rotated relative to the second module, the trigger piece is separated from the wedging piece along with the first module such that the one end of the wedging piece is wedged with the third module and the second module is locked to the third module; when the second module is rotated relative to the third module, the actuating piece is separated from the third module along with the second module and the join piece is driven by the actuating piece to wedge with the trigger piece such that the second module is locked to the first module. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method of operating a multi-function printer, the multi-function printer comprising an ADF, a scanner, a main body, a trigger piece, a wedging piece, an actuating piece and a join piece, the scanner being positioned on the main body and pivotally connected to the main body, the ADF being disposed on the scanner and pivotally connected to the scanner, the trigger piece being fixed to the ADF and protruded into the scanner, the wedging piece being disposed in the scanner and having one end protruding under the scanner, the actuating piece being disposed in the scanner, the join piece being disposed in the scanner and having a first end connected to the actuating piece and a second end positioned close to the trigger piece, the method comprising:
-
setting the scanner onto the main body and setting the ADF onto the scanner such that the trigger piece presses against the wedging piece and the actuating piece presses against the main body; rotating the ADF relative to the scanner to separate the trigger piece from the wedging piece such that the one end of the wedging piece is wedged with the main body and the scanner is locked to the main body; and rotating the scanner relative to the main body to separate the actuating piece from the main body such that the join piece is driven by the actuating piece to wedge with the trigger piece and the scanner is locked to the ADF. - View Dependent Claims (19, 20)
