Abstract

In a passbook printer having an auto turn-page (ATP) feature in which a passbook page or leaf is automatically turned for printing transactions on the next page when a page is printed over and some data of transactions to be printed still remains, a unique ATP mechanism is provided for positively performing this function. (Image Omitted) Figs. 1a and 1b show the schematic plan view and front view, respectively, of the mechanism with its major components. As shown in these figures, a passbook 1 is fed to a position under an ATP roller 2 for the ATP operation to be performed in the manner shown in figs. 2-7. In Fig. 2, a gate 3 is opened and the ATP roller 2 comes down to press the passbook 1 against a bottom plate 4 and starts rotating to frictionally deform the upper leaf of the passbook 1.

Auto Turn-Page Mechanism for Passbook Printer

In a passbook printer having an auto turn-page (ATP) feature in which a passbook page or leaf is automatically turned for printing transactions on the next page when a page is printed over and some data of transactions to be printed still remains, a unique ATP mechanism is provided for positively performing this function.

Figs. 1a and 1b show the schematic plan view and front view, respectively, of the mechanism with its major components. As shown in these figures, a passbook 1 is fed to a position under an ATP roller 2 for the ATP operation to be performed in the manner shown in figs. 2-7. In Fig. 2, a gate 3 is opened and the ATP roller 2 comes down to press the passbook 1 against a bottom plate 4 and starts rotating to frictionally deform the upper leaf of the passbook 1. A recess 5 in the bottom plate 4 serves to increase the contact area of the ATP roller 2 and the upper leaf and also to bend the passbook 1 near its center-fold. Thus, the possibility of the ATP roller 2 slipping on the passbook 1 is completely reduced.

Then, as shown in Fig. 3, the ATP roller 2 is lifted up slightly to unbend the passbook 1 so that, if two or more leaves have been deformed together, the upper leaf can be more slowly unbent than the other leaves. This is because the friction between the upper leaf and the ATP roller 2 is higher than that between the upper leaf and the next leaf. Thus, the upper leaf...
