Modular book binder










Image Number 5 for United States Patent #5338125.

A modular binder is provided for quickly and easily binding a sheaf of papers to form a book. The modular binder comprises a pair of cover modules each including a cover leaf hinged to a spine segment, wherein the spine segments are identical and are adapted to interfit in face-to-face relation to retain the sheaf of papers. A spine lock clip is provided to interconnect the spine segments with a variable spacing according to the thickness of the paper sheaf. Auxiliary communication and/or entertainment modules such as an audio cassette player, one or more audio cassettes, etc., can be mounted onto one or both cover leaves of the two cover modules.
