Abstract: Disclosed is a lower folding device for forming dumplings. The lower folding device for forming dumplings according to the present invention comprises: a dumpling skin pressing unit which includes a plurality of dumpling skin folding units that are simultaneously operated, and which drives the plurality of dumpling skin folding units at a preset position; a cam rail unit for folding which is arranged adjacent to the dumpling skin pressing unit and is connected to the dumpling skin pressing unit to move the dumpling skin folding units; and a movement unit for folding which is connected to the dumpling skin pressing unit and moves the dumpling skin pressing unit relative to the cam rail unit for folding.

Abstract: An in-line dumpling molding system is disclosed. The in-line dumpling molding system according to the present invention comprises: a dumpling wrapper cutting device, which cuts a supplied dough sheet to form dumpling wrappers; a dumpling-molding lower folding device, which is disposed below the dumpling wrapper cutting device, on which the cut dumpling wrappers are loaded, and which presses and folds the dumpling wrappers onto which dumpling fillings have been supplied; and a sealing device, which is disposed above the dumpling-molding lower folding device, and presses and seals the folded dumpling wrappers.

Abstract: A digital processor having a key input unit and a key input method are disclosed. The key unit includes: a base that is fixed at the central position of the key unit; a slider that horizontally moves in parallel to the horizontal plane of the base by the user's operation; a frame that supports the slider so as to horizontally move; and a restoration unit that gives a resistive force against the horizontal movement of the slider and restores the horizontally-moved slider to an original position. Accordingly, it is possible to reduce the number of keys by increasing the number of information to be input by the use of a single key.
