DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a page turning mechanism utilizing a restoring force due to the curvature of a booklet and a frictional force between a rubber roller and a paper portion, and more particularly to a page turning mechanism of a passbook printer.

[0002]

2. Description of the Related Art As a well-known example of a conventional page turning mechanism of a booklet, Japanese Patent Application Laid-Open No. 3-19895 is known.

In the configuration of the page turning mechanism disclosed in this publication, a sensor and a transport system for stopping the sheet at a page turning position in an area different from the printing section are arranged. In the turning section, a movable guide operated by an actuator was required to create a curved area of the sheet. In addition, in order to stabilize the bending operation of the sheet, a mechanism for pushing up the sheet below the sheet was required. Further, a rubber roller which is driven independently for bending and peeling at the turning portion is also required. In the printing section, a sensor, a paper transport section, and a movable print head are provided in an area different from the turning section, and a platen that moves up and down in conjunction with the paper thickness is required individually.

Next, a conventional page turning operation will be described.

[0005] The paper stops at the turning area with the sensor as a trigger. Next, in order to secure an area for curving the sheet, the movable guide is retracted by the actuator.
The push-up mechanism below the sheet is raised to bend the sheet upward, and the sheet is squeezed and brought into close contact with the turning roller. next,
The push-up mechanism and the press roller below the turning roller are retracted downward. After turning the turning roller to separate the first and second sheets, the turning roller was reversed to complete the page turning.

[0006]

In the above-described conventional page turning mechanism of the passbook printer, a dedicated page turning mechanism is required in an area separate from the printing section. I was Further, since the transport path is long, the processing time is long, and the reliability is low.

[0007]

Means for Solving the Problems A first invention of the present application is a stamp according to the present invention.
Printing mechanism consisting of a character head and a platen, and
A transport for carrying a passbook and outputting the passbook from the printing mechanism
A feeding guide and a printing mechanism, and
A roller for turning and carrying the bankbook.
In the page turning mechanism of the passbook printer obtained,
Can easily bend the paper when turning the passbook.
The paper is pushed up from below in order to
You.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a top view of an embodiment of the page turning mechanism of the passbook printer according to the present invention, FIG. 2 is a side view of an embodiment of the page turning mechanism of the passbook printer of the present invention, and FIGS. FIG. 6 is an operation explanatory view of the page turning mechanism of the passbook printer of the present invention.

As shown in FIGS. 1 and 2, the page turning mechanism of the passbook printer according to the present invention includes a rubber roller (A) 7 and a rubber roller (B) 8 for conveying the passbook 1 before and after the printing unit. In order to be able to operate independently, a motor 9 as a drive source and a drive transmission belt 10 for drive transmission are separately provided. A transport guide 1 is provided above and below the transport section.
1 is arranged. Immediately before the printing unit, a transmitted light sensor 2 for detecting the end of the passbook 1 is provided, and the trigger of the printing operation, the turning operation, and the end are detected.

Next, the configuration of the printing unit will be described. It has a dot impact type print head 3 that moves perpendicular to the paper transport direction, and a platen 4 that can be moved up and down to optimize the impact force with respect to the thickness of the passbook 1. I have arranged.

Next, the operation will be described with reference to FIGS.

When the pages of the passbook 1 are turned, the passbook 1 is stopped by the transmitted light sensor 2 at the passbook turning position. Next, the print head 3 is retracted outside the transport path to secure a curved area, and an empty area is secured above the transport path (FIG. 3). Next, the platen 4 below the sheet is moved upward to bend the passbook (FIG. 4). Here, the retraction roller (A)
5 and retract the rubber roller (A) 7 in the direction of the arrow,
The platen 4 is lowered (FIG. 5). Further, the rubber roller (A) 7 is rotated in the direction of the arrow, and one sheet of the passbook is passed over the rubber roller (A) 7. Next, after the retraction roller (A) 5 is moved to the transport position again, the page turning is completed by rotating the rubber roller (A) 7 and the rubber roller (B) 8 in a direction opposite to the previous rotation direction.

As can be seen from the above description, according to the present invention, when turning a page of a passbook printer, an area for curving a sheet is used by using an empty area at the time of moving a print head by printing, and pushing up for curving a sheet. The mechanism is miniaturized by using a movable platen mechanism that is located below the print head of the printing unit and moves up and down according to the thickness of the medium to give an appropriate impact force. , Low cost and high reliability can be realized.

[0019]

As described above, the page turning mechanism of the passbook printer according to the present invention can turn pages in the area of the printing section, so that the number of components can be greatly reduced and the size of the unit can be reduced. In addition, there is an effect that downsizing, cost reduction, and high reliability can be realized as compared with the conventional apparatus.
