Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application is based on, and claims priority from, China Patent Application No. 202322631914.5, filed Sep. 26, 2023, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION Field of the Invention The present invention generally relates to a scanner with a foldable stand, and more particularly to a scanner with a foldable stand which is automatically unfolded with an opening of an output tray. Description of Related Art Referring to FIG. 9, in order to facilitate scanning a large quantity of documents by a user, a conventional automatic scanner 100′ is equipped with an input tray for storing the documents which are to be fed, and an output tray 20′ for loading the ejected documents. Simultaneously, in order to reduce a size of the conventional automatic scanner 100′ and facilitate carrying the conventional automatic scanner 100′, the input tray and the output tray 20′ are often designed to be detachable or foldable. Referring to FIG. 9, the conventional automatic scanner 100′ includes a housing 10′. The output tray 20′ is pivotally connected to a rear of the housing 10′. Therefore, the conventional automatic scanner 100′ is able to feed the scanned documents to the output tray 20′, and the scanned documents are temporarily stored to the output tray 20′. However, when too many documents are piled up in the output tray 20′, a centre of gravity of the conventional automatic scanner 100′ easily tends to be shifted and tilted, so that it is necessary to provide a supporting stand for the conventional automatic scanner 100′. In view of the above-mentioned problems, it is necessary to provide an innovative scanner with a foldable stand, in order to keep a size of the innovative scanner with the foldable stand light, thin and portable, the scanner with the foldable stand is automatically unfolded with an opening of an output tray. BRIEF SUMMARY OF THE INVENTION An object of the present invention is to provide a scanner with a foldable stand which is automatically unfolded with an opening of an output tray. The scanner with the foldable stand includes a housing, a first output tray foldably covered to an upper portion of a rear of the housing, a second output tray foldably covered to a top of the housing, a supporting stand and an abutting element. Two opposite ends of the first output tray have a starting end pivotally connected to the rear of the housing, and a swingable connecting end connected to a free end of the starting end, respectively. A middle of an outer surface of the first output tray is recessed inward to form a holding groove. Two opposite ends of the second output tray have a pivot end pivotally connected to a free end of the connecting end, and a swingable terminal end connected with a free end of the pivot end, respectively. The supporting stand is foldably fastened in the holding groove. Two opposite ends of the supporting stand have a fixing end pivoted to the second output tray, and a movable end which is swingable, respectively. A pivoting position between the fixing end and the second output tray is located at an outside of the pivot end. The abutting element is formed at a middle of the connecting end of the first output tray. The abutting element contacts with an inner portion of the supporting stand. When the first output tray is covered to the upper portion of the rear of the housing, and the second output tray is covered to the top of the housing, the supporting stand is fastened in the holding groove. When the first output tray and the second output tray are fully unfolded, the movable end of the supporting stand projects out of the holding groove. Another object of the present invention is to provide a scanner with a foldable stand. The scanner with the foldable stand includes a housing, an output tray foldably covered to the housing, a supporting stand and an abutting element. The output tray includes a first output tray foldably covered to an upper portion of a rear of the housing, and a second output tray foldably covered to a top of the housing. Two opposite ends of the first output tray have a starting end pivotally connected to the rear of the housing, and a swingable connecting end connected to a free end of the starting end, respectively. A middle of an outer surface of the first output tray is recessed inward to form a holding groove. Two opposite ends of the second output tray have a pivot end pivotally connected to a free end of the connecting end, and a swingable terminal end connected with a free end of the pivot end, respectively. The supporting stand is foldably fastened in the holding groove. Two opposite ends of the supporting stand have a fixing end pivoted to the second output tray, and a movable end, respectively. The movable end is swingable with respect to the first output tray and the second output tray. A middle of an inner portion of the supporting stand w
