The utility model provides a sheet supporting device. Rigidity of two parts can be also highly maintained even under the condition that the second supporting part which can be pulled-out or pushed-in relative to the first supporting part is pulled-out to the maximum extent. The sheet supporting device comprises the first supporting device, the second supporting device and a connecting part. The second supporting part can be moved to the pushed-in first position and the pulled-out second position relative to the first supporting part, and the connecting part can be connected relative to the first supporting part and the second supporting part respectively in the mode that the connecting part can slide in the pulled-out direction. When the second supporting part is located at the second position, the front end of the connecting part is located on the front side relative to the front end of the first supporting part, and the rear end of the connecting part is located on the rear side relative to the rear end of the second supporting part. When the second supporting part is located at the first position, the front end of the connecting part is located on the rear side relative to the front end of the first supporting part and the front end of the second supporting part, and the rear end of the connecting part is located on the front side relative to the rear end of the first supporting part and the rear end of the second supporting part. |
