CUTTING DEVICE AND CUTTING METHOD

[Problem] To provide a technique by which, in cutting apparatus and a method for cutting into a small block such as a paper money or a postcard out of a large sheet, the cutting accuracy of a manufactured small block can be improved, and steps can be simplified and cutting equipment can have a smaller size simultaneously. [Solution] A cutting apparatus comprises: a first pusher for pushing and conveying the left side of the cut large sheet block, of which two adjacent reference sides that have been jogged as an upper side and a left side are placed on the cutting apparatus, toward the right side direction; a second cutting means for cutting the right side of the large sheet block- pushed and conveyed by the first pusher and sequentially cutting the right end of the large sheet block while interacting with the pushing conveyance by the first pusher to divide the sheet into long column unit blocks in the up-and-down direction; a right side removal means for removing the remaining portion after the right side cutting by the second cutting means; a column unit block conveyance means for conveying the column unit blocks in the right side direction while maintaining a predetermined interval thereamong; a second pusher for pushing and conveying the upper sides of the cut column unit blocks toward the lower side direction; a fourth cutting means for cutting the lower side of the column unit block pushed and conveyed by the second pusher and sequentially cutting the lower end of the column unit block into small blocks while interacting with the pushing conveyance by the second pusher; and a lower side removal means for removing the remaining portion after the lower side cutting by the fourth cutting means.
