The guiding member has a base board. A front of the base board defines a guiding portion defining a horizontal recess. Each adjusting plate is pivoted to an outside edge of the base board. The push bars are movably received in the horizontal recesses and capable of sliding in the horizontal recesses to drive the corresponding adjusting plates to rotate upward or free the corresponding adjusting plates therefrom. Each rotating member is pivoted to a front of the guiding portion. When the rotating member is turned down, the rotating member touches the push bar and pushes the push bar to move rearward so that further drives the adjusting plate to rotate upward till being perpendicular to the base board.

A document feeding mechanism includes a driving shaft, a document blocking unit, a tray, an elastic unit and an actuating unit. The tray is pushed up to connect the document blocking unit by the elastic unit. The actuating unit is coupled to the driving shaft and abutted against the tray for pushing down the tray to separate from the document blocking unit. The actuating unit will be driven to allow the tray to be pushed to swing up by the elastic unit for blocking documents. The actuating unit will be driven to abut against the tray for pushing the tray to swing down for separating the tray from the document blocking unit for conveying the documents. Therefore, the document feeding mechanism has high reliability for blocking the documents.

A sheet pressing apparatus assembled to a file processing equipment which has an input tray for stacking sheets and a pickup roller for feeding sheets. The sheet pressing apparatus includes a sheet pressing assembly movably mounted to the file processing equipment, a driving device including a connecting member and a stepping motor, a sensor unit and a control system. The sheet pressing assembly is driven by the stepping motor to be descending through the connecting member. When the sheet pressing assembly descends, the sensor unit touches the sheets and sends a signal to the control system, the control system figures out the thickness of the sheets by calculating steps the stepping motor having passed, then the control system makes the stepping motor further move with certain steps to drive the sheet pressing assembly further descend to apply a suitable pressure on the sheets.

A sheet processing apparatus includes a sheet-table unit, a sheet-separating unit, a convey unit, a discharge unit, a sheet processing unit, and a sensor arranged at an upstream end of the convey unit and spaced from the discharge unit with a predetermined distance. The convey unit has at least one convey roller, at least one convey pulley, and an elastic device connected with the convey pulley. The elastic device has a stepping motor, a transmission system, a shaft and at least one torsional spring mounted on the shaft. Two ends of the torsional spring is connected with the convey pulley. When the signal resulted from a rear end of the sheet apart from the sensor is sent to the system controller, the stepping motor is commanded by the system controller to rotate the shaft. The torsional spring is twisted to make the convey pulley move away from but still contact with the convey roller.
