Abstract

A passbook printer is required to guide a passbook to be fed along a feed path without any skewing, since a magnetic stripe attached to its cover has to be read or encoded by a magnetic head. Also, it is an advantage for the printer to have the capability of printing a cut form. Disclosed is a unique form-feed mechanism which can feed properly either a passbook or A cut form.

Print Medium Feed Mechanism with Passbook Guide Plate

A passbook printer is required to guide a passbook to be fed along a feed path without any skewing, since a magnetic stripe attached to its cover has to be read or encoded by a magnetic head. Also, it is an advantage for the printer to have the capability of printing a cut form. Disclosed is a unique form-feed mechanism which can feed properly either a passbook or A cut form.

A print medium, such as a passbook or a cut form, is held between upper rolls 1 and lower rolls 2 and fed to the print station through the space between an upper plate 3 and a lower plate 4. The upper rolls 1 are rotated by a motor through a shaft 5 for feeding the print supported by one edge of an arm 7 which is pivotally mounted on the printer frame and spring loaded so that the lower rolls 2 can be pressed against the upper rolls 1. The lower plate 4 is provided with a step 8 which extends to the print station, so that the passbook can be easily placed in position and guided not to skew when it is fed into and out of the print station through the magnetic head 9.

When printing a cut form which is always wider than a passbook, it also can be held by the rolls 1 and 2 for feeding. Although the wide cut form is placed on the lower plate 4 beyond the step 8, it is not so strictly required to keep its path as the passbook since the form is not provided with a magnetic stripe to be read or encoded.
