[0021] In order to explain the technical content, structural features, achieved objectives and technical effects of the present invention in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0022] See also Figure 1 and Figure 2A scanner 100 shown in this preferred embodiment comprises: a scanner body 10; a first paper output tray 21, the first paper output tray 21 having a paper output tray starting end 21a pivotally connected to the rear side of the scanner body 100 and a swingable paper output tray connecting end 21b; a second paper output tray 22, the second paper output tray 22 having a pivot portion 22a pivotally connected to the paper output tray connecting end 21b and a swingable paper output tray ending end 22b; and an extended paper output tray 23, the extended paper output tray 23 being movably pivotally connected to the second paper output tray 22 and moving with the second paper output tray 22. The first paper output tray 21, the second paper output tray 22 and the extended paper output tray 23 can be folded and stored at the rear side edge and the top of the scanner body 10, and unfolded to form a paper output tray 20 for carrying documents when scanning starts. For the convenience of description, the direction of the paper output tray 20 is defined as follows in this specification: the "inner side" is defined as the side that contacts the paper when the first paper output tray 21 and the second paper output tray 22 are unfolded, and the side that contacts the scanner body 10 when the first paper output tray 21 and the second paper output tray 22 are folded. The "outer side" is defined as the side that faces the desktop when the first paper output tray 21 and the second paper output tray 22 are unfolded, and the side that faces the outside when the first paper output tray 21 and the second paper output tray 22 are folded.

[0023] Please see again Figure 3 In a preferred embodiment shown in the figure, the second paper output tray 22 includes a receiving slot 30, the receiving slot 30 extends toward the end 22b of the paper output tray and forms a slot hole 31 at the end 22b of the paper output tray. An extended paper output tray shaft hole 32 is provided at the receiving slot 30 near the end 22b of the paper output tray. The extended paper output tray shaft hole 32 is arranged at one side of the receiving slot 30 near the slot hole 31 and is perpendicular to the second paper output tray 22 to pivotally connect the extended paper output tray 23; an extended paper output tray torsion spring 23a is installed between the extended paper output tray 23 and the extended paper output tray shaft hole 32 to apply a torque to the extended paper output tray 23 to rotate toward the slot hole 31.

[0024] A release hook shaft hole 33 is provided in the receiving slot 30 near the pivot portion 22a. The release hook shaft hole 33 is provided on a side of the receiving slot 30 away from the slot hole 31 and perpendicular to the second paper output tray 22; a release hook 40 movably pivoted to the release hook shaft hole 33, and the release hook 40 is provided with a release hook shaft 41 movably pivoted to the release hook shaft hole 33, a hook arm 42 extending from the release hook shaft 41 to the extended paper output tray 23, and a A release hook actuator arm 43 extending to the opposite side of the hook arm 42, and a release hook torsion spring 44 arranged between the release hook shaft 41 and the extended paper output tray shaft hole 32, the release hook torsion spring 44 applies a torque to the hook arm 42 to rotate toward the extended paper output tray 23; and a one-way actuator 50, the one-way actuator 50 is movably pivoted on the release hook actuator arm 43 and the axial direction of the one-way actuator 50 is orthogonal to the axial direction of the release hook shaft 41.

[0025] Please see again Figure 4 The one-way actuator 50 includes an actuator shaft 51, an actuator arm 52 extending from the actuator shaft 51, and a snap arm 53 extending to the opposite side of the actuator arm 52. Figure 4 and Figure 5 The one-way actuator 50 is movably pivoted to the release hook 40, and the buckle arm 53 is disposed adjacent to the release hook 40, while the actuator arm 52 is disposed away from the release hook 40. For the sake of convenience, the rotation direction of the one-way actuator 50 is defined as follows in the following specification, where the direction in which the buckle arm 53 presses against the release hook 40 is defined as the "positive direction", and when the one-way actuator 50 rotates in the "positive direction", the side of the actuator arm 52 and the buckle arm 53 facing the rotation direction is defined as the "front side", and the side of the actuator arm 52 and the buckle arm 53 facing away from the rotation direction is defined as the "back side".

[0026] Please see again Figures 5 to 7 , an actuating slope 52a is provided on the back of the actuating arm 52. At the same time, the first paper output tray 21 is provided with a protrusion 30 extending toward the pivot portion 22a, so that the protrusion 30 contacts the actuating arm 52 when the first paper output tray 21 and the second paper output tray 22 are opened and closed. In addition, in order to fix the extended paper output tray 23, the extended paper output tray 23 is provided with a fixing hook 23a, and the fixing hook 23a is configured to be hooked with the hook arm 42.

[0027] Please see again Figure 8 and Fig. 9The process of unfolding the paper output tray 20 in the utility model is as follows. When the user opens the second paper output tray 22, the protrusion 30 begins to push against the actuating slope 52a and applies a force perpendicular to the actuating slope 52a to the actuating arm 52. The force causes the one-way actuating member 50 to obtain a forward rotation torque and a force component toward the end 22b of the paper output tray. The torque causes the buckle arm 53 to press against the release hook 40, thereby causing the one-way actuating member 50 to buckle on the release hook 40 and move together, while the force component toward the end 22b of the paper output tray pushes the actuating arm 52 to swing toward the end 22b of the paper output tray, thereby causing the buckle arm 53 to disengage from the extended paper output tray 23. At this time, the extended paper output tray 23 rotates toward the slot 31 under the action of the extended paper output tray torsion spring 23a and pops out to the outside of the second paper output tray 22.

[0028] Please see again Fig.10 and Fig.11 The folding process of the scanner 100 of the present invention is as follows. The user first retracts the extended paper tray 23 inward into the receiving slot 30, and fixes the extended paper tray 23 in the receiving slot through the hook arm 42. Then the user closes the second paper tray 22 in the direction of the first paper tray 21. At this time, the outer side of the protrusion 30 begins to push against the front of the actuating arm 52, thereby applying a torque in the reverse direction to the one-way actuating member 50. Under the action of the reverse torque, the buckle arm 53 rotates in the direction away from the release hook 40 and separates from the release hook 40, thereby preventing the buckle arm 53 from being separated from the extended paper tray 23 when the protrusion 30 pushes against the one-way actuating member 50.

[0029] In summary, a scanner in the utility model comprises: a scanner body; a first paper output tray, wherein the first paper output tray is provided with a paper output tray starting end pivotally connected to the rear side of the scanner body and a swingable paper output tray connecting end; a second paper output tray, wherein the second paper output tray is provided with a pivot portion pivotally connected to the paper output tray connecting end and a swingable paper output tray end; an extended paper output tray, wherein the extended paper output tray is movably pivotally connected to the second paper output tray; and an extended paper output tray torsion spring, wherein the extended paper output tray torsion spring is arranged between the second paper output tray and the extended paper output tray to exert a spring on the extended paper output tray to eject the second paper output tray. a release hook movably pivoted to the second paper output tray to fix the extended paper output tray and release the extended paper output tray when triggered, and the pivot direction of the release hook is perpendicular to the surface of the second paper output tray; and a one-way actuator, the one-way actuator is disposed between the release hook and the first paper output tray to trigger the release hook and release the extended paper output tray when the first paper output tray and the second paper output tray are unfolded, and to avoid triggering the release hook when the first paper output tray and the second paper output tray are folded, and to automatically unfold the extended paper output tray through the action of the one-way actuator.
