DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter mechanism used for a printing apparatus for inserting a passbook and performing printing, and for positioning the passbook during a printing operation.

[0002]

2. Description of the Related Art A conventional printing apparatus for performing printing by inserting a passbook has a shutter mechanism for positioning the passbook during a printing operation. However, since there is no vertical movement but only a rotation movement in a horizontal plane, when a passbook exists at a printing position of the printing apparatus, the shutter and the passbook interfere with each other, causing a jam.

FIG. 4 is a view showing an example of a shutter mechanism of such a conventional printing apparatus. FIG.
(B) is a front view. FIG. 5 is a plan view showing the operation state of the example of FIG.

In FIG. 4, a shutter 11 has a link 16
Is connected to the solenoid 12 via the., And by operating the solenoid 12, it rotates in the direction of arrow A in the horizontal plane to position the end face of the passbook (the operation position is indicated by reference numeral 11a). At this time, as shown in FIG. 5, when the passbook 7 exists below the print head 13 (print position) of the printing apparatus, the shutter 11 and the passbook 7 interfere with each other and cause a jam. . In particular, when the bankbook 7 is raised or broken, the end face of the bankbook 7 is
Since 1 is pushed strongly, there is a great effect.

Therefore, in order to avoid this, the conventional printing apparatus transports the passbook 7 and retracts it from under the print head 13 to operate the shutter mechanism, and then transports the passbook 7 again to print the printing position. It is necessary to perform the operation of returning to.

[0006]

As described above, in the conventional shutter mechanism of the printing apparatus, since the operation of the shutter is only a rotational movement in a horizontal plane, the shutter and the passbook interfere with each other to cause a jam. In order to avoid this, the passbook must be transported and retracted from below the print head to operate the shutter mechanism, and then the passbook must be transported again and returned to the printing position. Therefore, there is a problem that the processing time is long.

[0007]

A shutter mechanism of a printing apparatus according to the present invention comprises: a shutter for positioning by pressing an end of a passbook at a printing position from above;
If no decision is made, the tip of the shutter should be
The shutter to the lower position.
When making a decision, make sure the tip of the shutter is above the passbook
After the shutter is positioned, the shutter is lowered and the tip
A parallel link mechanism for performing the up-down movement and the back-and-forth movement of the shutter so as to press the passbook, and a solenoid and a gear train for driving the parallel link mechanism are provided.

[0008]

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

FIG. 1 shows an embodiment of the present invention.
2A is a plan view, FIG. 2B is a front view, FIG. 2 is a front view showing an example of a printing apparatus equipped with the embodiment of FIG. 1, and FIG. 3 shows the operation of the shutter mechanism of the embodiment of FIG. In the plan view, (a)
Is a diagram showing an intermediate operation state, and (b) is a diagram showing a final operation state.

The printing apparatus shown in FIG. 2 sucks the passbook 7 from the suction / discharge port 21 and conveys the passbook 7 to the position of the barcode reading section 22, and the barcode reading section 22 reads the barcode provided on each page of the passbook 7. . Subsequently, the passbook 7 is transported to the position of the print head 3 and printed. If the printing on the passbook 7 extends to the next page, the passbook 7 is transported to the position of the page turning unit 23, where the page is turned, and conveyed to the barcode reading unit 22 to determine whether the page turning is correctly performed. After the confirmation, the sheet is conveyed again to the position of the print head 3 and printed on the next page. When the printing is completed, the passbook 7
It is transported to the position of the magnetic recording / reproducing unit 24, where the magnetic data is written and discharged from the suction / discharge port 21.

As shown in FIG. 1, a shutter mechanism 10 for positioning a passbook during a printing operation is provided on the side of the print head 3. The shutter mechanism 10
In order to avoid interference with the print head 3 moving in the direction of arrow B, the print head 3 is provided below the print head 3 when the print head 3 is in operation (see FIG. 1B).

The shutter mechanism 10 includes a driving solenoid 2, a fan-shaped gear 4 that rotates by the operation of the solenoid 2, a pinion 8 that meshes with the gear 4 and rotates around a fixed shaft 9. A link 5 having one end fixed to the pinion 8 and rotating with the pinion 8, a link 6 provided in parallel with the link 5 and having the same length as the link 5 rotatably supported at one end, and a link 5 at the end And a shutter 1 rotatably coupled to the other end of the link 6 at an intermediate point, and having a distal end protruding toward the print head 3.

Next, the operation of the embodiment constructed as described above will be described with reference to FIGS.

In the non-operation state, as shown in FIG. 1B, the link 5 and the link 6 are in the state of being leftmost to the left, and the leading end of the shutter 1 is located below the print head 3. positioned.

When the shutter mechanism 10 is operated,
The solenoid 2 is operated while the print head 3 is retracted. By the operation of the solenoid 2, FIG.
As shown in (a), the gear 4 rotates in the direction of arrow C, and the pinion 8 meshing therewith rotates in the direction of arrow D. The link 5 and the link 6 are lifted by the movement of the pinion 8, and the state shown in FIG. Therefore, the tip of the shutter 1 is located above the bankbook 7.

Subsequently, when the solenoid 2 operates, FIG.
As shown in (b), the leading end of the shutter 1 advances toward the bankbook 7 and descends, and presses the end of the bankbook 7 from above to pass the bankbook 7.
Perform positioning. Therefore, the positioning operation of the passbook 7 can be performed by operating the shutter mechanism unit 10 in a state where the passbook 7 is at the printing position, and it is not necessary to perform the evacuation operation of the passbook 7.

[0017]

As described above, the shutter mechanism according to the present invention comprises a shutter for positioning the passbook at the printing position by pressing the end of the passbook from above, and a parallel shutter for performing the vertical movement and the forward / backward movement of the shutter. By providing a link mechanism, a solenoid and a gear train for driving the parallel link mechanism, there is an effect that the shutter mechanism can be operated in a state where the passbook is at the printing position to perform the passbook positioning operation. Therefore, since it is not necessary to perform the passbook saving operation, the processing time can be shortened.
