发明名称 Reading aid apparatus, especially a copyholder for typewriters
摘要 The transcribing work of a typist is facilitated by a reading aid in the form of a copyholder which has a holder cylinder of transparent material into which a copy to be transcribed is insertable. A support provides for rotatably locating the copyholder substantially in the typist's line of vision toward the keyboard and the typed line. The hollow cylinder is rotatable either by hand or by a motor driven gear mechanism for stepping the cylinder from line to line of the copy. The copy is insertable either at one open end of the cylinder or through a slot in the cylinder jacket.
