Paper Feed Mechanism for Passbook Printer

Fig.1 and Fig.2 show the front view and side view of the paper feed device of a passbook printer. Fig.1 shows the condition that the passbook is fed from the front to the rear. The front and rear guides are the so-called flapper type which rotates around a shaft. The carrier with the print head moves to the right side, when the passbook is fed into the device from the front. Then, the rear guide is opened because the carrier pushes the rear lever and rotates the rear guide. The front guide is closed by the spring of the front guide which is shown in Fig.2. And the closed guide pushes down the curled passbook. The curled passbook is fed into the rear without a paper jam by the rear guide.

Fig.2 shows the condition that the passbook is fed from the rear to the front. The carrier moves to the left, when the passbook is fed from the rear. Then, the front guide is opened because the carrier pushes the front lever and rotates the front guide. The rear guide is closed by the spring. And the closed guide pushes down the curled passbook. The curled passbook is fed into the front side without a paper jam by the front guide.
