    • An apparatus (10) for advancing a record medium (32) in a printer. The apparatus includes a rotatable member (12) connected to the platen (18) of the printer for rotation therewith, and also having teeth (44) on the periphery thereof and a driving surface (45) thereon. The apparatus (10) also includes a rotatable driving unit (14) having at least one driving member or camming lug (74, 76) thereon to engage the teeth (44) and thereby incrementally rotate the rotatable member (12) as the driving unit (14) is rotated. The apparatus further includes a coupling means (16, 94) moveable between first and second positions whereby the coupling means (16) is operatively disconnected from the driving unit (14) and the rotatable member (12) when the coupling means (16) is in the first position, and whereby the coupling means (16) when in the second position is effective to disconnect the camming lug (74, 76) from the teeth (44) and to also operatively connect the driving unit (14) with the driving surface (45) to continuously rotate the rotatable member (12) as the driving unit (14) is rotated.

    • A privacy tablet whereby an individual may make a written of other printed input information on a writing surface and thereafter immediately cover the portion of the writing surface so as to protect the confidentiality, security or privacy of the information from the view of subsequent users of the tablet. The covering operation may be manual or may be motorized and automated. Moreover, the motion of the cover may be restricted from unauthorized reversal and resultant observation of the information by a locking means. Lastly, any of the numerous generally planar surfaces of the tablet are well suited for and may be utilized for the imprinting of graphical or advertising material for the purposes of advertising or promotion.
