Data processing apparatus
First Claim
1. A data processing apparatus comprising a guide unit having an intermediate roller and an arc-shaped guide surface composing a substantially arc-shaped curved transportation unit inside an external case;
- a paper feed roller pair, which nips and conveys a transported medium conveyed from said curved transportation unit toward a processing position, disposed at a specific distance from a discharge end of said curved transportation unit, wherein said guide unit comprises an auxiliary guide member which projects from said discharge end of said curved transportation unit toward said paper feed roller pair and guides said transported medium conveyed toward said paper feed roller pair, said guide unit rendered to move circularly and open and close in unison with an outside wall portion of said external case positioned on the outside of said guide unit;
opening/closing levers for locking and unlocking a lock unit which restricts circular motion of said guide unit in a closed position; and
an auxiliary guide linking mechanism for retracting said auxiliary guide member in a direction separating from said paper feed roller pair in conjunction with said unlocking operation of said lock unit by said opening/closing levers.

Abstract
A data processing apparatus having a construction for guiding a transported medium conveyed from a curved transportation unit enables opening and closing the guide unit. The data processing apparatus 1 has an intermediate roller 39 and guide portion 38 constituting a curved transportation unit 23 inside the printer case 7, and a paper feed roller pair 25 and 26 for nipping and conveying paper P conveyed from the curved transportation unit 23 disposed a specific distance from the curved transportation unit 23. The guide portion 38 has an auxiliary guide member 51 and can move circularly open and closed in unison with an outside wall unit 16. The auxiliary guide member 51. projects toward the paper feed roller pair 25 and 26 and guides the paper P. An auxiliary guide linking mechanism 53 causes the auxiliary guide member 51 to retract away from the paper feed roller pair 25 and 26 in conjunction with the unlocking operation of opening/closing levers 41 and 42.
