Bank checking system

A bank checking system comprising:

• a cover member which may selectively be opened and laid out flat and closed by folding along a fold line which divides said member into approximately equal halves, each said half carrying receiver means for holding components of said system between said halves when said folding member is closed;
• a plurality of bank checks, each carrying indicia near a corner of its face, and each foldable along a pair of approximately parallel fold lines so that a first segment including less than one-third the area of the check is folded over against the face of the check, and a second segment, opposite said first segment and including said indicia is foldable towards said first segment, said plurality of checks being held in stacked arrangement by one of said receiver means such that the first said segment of each check is held between the face of that check and the back of an adjacent check and the second segment of each check is oriented parallel the corresponding second segments of the other of said plurality of checks so that they may be folded simultaneously for containment between the halves of said folding member when said folding member is closed and unfolded when said folding member is opened so that any of said checks may selectively be removed from said stacked arrangement without disturbing the remaining checks;
• and
• register means, including a continuous sheet held by the other of said receiver means and folded into segments defined by a series of approximately parallel fold lines, alternating segments being folded in opposite directions so that the entire sheet may be collapsed for containment between the halves of said folding member when said folding member is closed and extended for the entry of data when said folding member is opened.
