A guiding and threading device for automatic pitch-adapted threading of data carriers such as punched tape. The device includes a base member having a tape support surface thereon, a feed wheel carried by the base member with a portion projecting above the support surface, a first pivotable member carried by the base member having a guiding surface positioned above the support surface and a second pivotable member opposed to the first pivotable member and having a guiding surface positioned above the support surface, the guide surfaces forming a tape receiving channel between the pivotable members and the support surface when the pivotable members are at an open position. The guide surface of the first pivotable member urges the tape into contact with the feed wheel when in a closed position. The second pivotable member is when the with means engaging the first pivotable member limiting movement of the first pivotable member with respect to the second pivotable member to provide a substantially continuous guide surface whenthe pivotable members are in the open position. |
