ABSTRACT:
A draft-paper rack structure for a computer which comprises a chassis, a supporting seat, a draft-paper rack, a transparent hood, a roller and an angle-setting knob; in fact, it is a clamp assembly for a typewriter to be designed into a clamp structure to be fastened on a computer keyboard so as to place a draft paper between the computer screen and the keyboard to enable a user to enter data into a computer without looking left and right (or back and forth) between a draft paper and the computer screen; a user may merely watch or scan up and down between a computer screen and a draft paper; the draft-paper rack structure is provided with an electro-motive adjusting knob to move a draft paper upward a suitable distance; a transparent hood mounted on the draft-paper rack has a line indicator for clearly indicating the lines of a draft being keyed in; the draft-paper rack can be clamped on a keyboard or a table having variable thickness, and it can also be placed on a desk; the rack can be set at a given slanting angle as desired, and the base elements of the chassis thereof can be extended backward so as to enable a draft paper to be placed at a stable position; the draft-paper rack can provide a user with a comfortable and practical key-in operation.
