Abstract
A medium passage switching mechanism disposed on a casing of an image forming device, includes a medium tray, a guiding component and a linking component. An entrance passage, a first exit passage and a second exit passage are formed inside the casing. The medium tray is pivoted to the casing. The guiding component is pivoted to the casing. The linking component is a one-piece structure and movably connected to the medium tray and the guiding component. When the medium tray pivots relative to the casing, the medium tray drives the linking component to drive the guiding component to pivot relative to the casing, so that the guiding component can guide a medium to enter into the first exit passage or the second exit passage selectively from the entrance passage.

A medium passage switching mechanism disposed on a casing of an image forming device, an entrance passage, a first exit passage and a second exit passage being formed in the casing, the medium passage switching mechanism comprising:
- a medium tray pivoted to the casing and pivotally switchable between a first position and a second position;
- a guiding component pivoted to the casing and pivotally switchable between a third position and a fourth position;
- and
- a linking component movably connected to the medium tray and the guiding component, the linking component being a one-piece structure;
- wherein the medium tray drives the linking component to drive the guiding component to pivot relative to the casing from the third position to the fourth position along a first pivoting direction when the medium tray is pivoted relative to the casing from the first position to the second position along the first pivoting direction, the guiding component guides a medium to enter into the second exit passage from the entrance passage when the guiding component is located at the fourth position, the medium tray drives the linking component to drive the guiding component to pivot relative to the casing from the fourth position to the third position along a second pivoting direction opposite to the first pivoting direction when the medium tray is pivoted relative to the casing from the second position to the first position along the second pivoting direction, and the guiding component guides the medium to enter into the first exit passage from the entrance passage when the guiding component is located at the third position.
An image forming device comprising:
- a casing, an entrance passage, a first exit passage and a second exit passage being formed in the casing;
- and
- a medium passage switching mechanism disposed on the casing and for guiding a medium to enter into the first exit passage or the second exit passage from the entrance passage, the medium passage switching mechanism comprising:
- a medium tray pivoted to the casing and pivotally switchable between a first position and a second position;
- a guiding component pivoted to the casing and pivotally switchable between a third position and a fourth position;
- and
- a linking component movably connected to the medium tray and the guiding component, the linking component being a one-piece structure;
- wherein the medium tray drives the linking component to drive the guiding component to pivot relative to the casing from the third position to the fourth position along a first pivoting direction when the medium tray is pivoted relative to the casing from the first position to the second position along the first pivoting direction, the guiding component guides the medium to enter into the second exit passage from the entrance passage when the guiding component is located at the fourth position, the medium tray drives the linking component to drive the guiding component to pivot relative to the casing from the fourth position to the third position along a second pivoting direction opposite to the first pivoting direction when the medium tray is pivoted relative to the casing from the second position to the first position along the second pivoting direction, and the guiding component guides the medium to enter into the first exit passage from the entrance passage when the guiding component is located at the third position.
