<p>A flexible drive mechanism for positioning bank passbooks and similar objects for use in conjunction with identification and entry posting apparatus, The functioning of the drive mechanism is made flexible by the use of eight rollers, four of which are power driven to serve as drive rollers (R2, R4, R6, R8) and four of which are idle rollers (R12, R14, R16, R18). The idle rollers are enabled to move relative to each other and to the drive rollers and are spring (S2, S4, S6, S8) biased to firmly engage bank passbooks and similar flat objects and press them against the power driven rollers. The rollers are enabled to accomodate the differences in thickness between part of the passbooks caused by either the presence of ridges, where sewn seams bind the pages of a book together, or by the presence of different amounts of paper. </p> |
