[0009]

Embodiments of the present invention will be described below.

FIG. 1 is a sectional view showing an embodiment of the passbook printer of the present invention, FIG. 2 is a plan view showing the passbook printer of FIG. 1, and FIG. 3 is a view showing the passbook printer of FIG. 4 to 6 are views for explaining the operation of the passbook printer of FIG.

As shown in FIGS. 1 to 3, the passbook printer includes a platen 1. A taper 1 a is provided on the upper surface of the platen 1 which is in contact with the passbook 4. The platen 1 is partially provided with a notch 1b. Thereby, the platen 1 is provided with a plurality of upper surfaces.

A transport guide 2 for guiding the transport of the passbook 4 is provided above the platen 1. The transport guide 2 is provided with a plurality of transport guide holes 2 b for projecting the upper surface of the platen 1. The transport guide hole 2b is provided with a taper 2a inclined inward. The periphery of the plurality of transport guide holes 2b of the transport guide 2 is a flat surface 2c.

Above the platen 1, a print head 3
Are movably arranged in the direction of arrow B. This arrow B
The direction is a direction orthogonal to the arrow A direction that is the transport direction of the passbook 4. Then, the platen 1 is moved up and down by a driving mechanism (not shown). The print head 3 is also moved in the direction of arrow B by a drive mechanism (not shown).

Next, the operation of the passbook printer having such a configuration will be described.

First, when the passbook 4 is transported in the direction of arrow A, as shown in FIG. 4, the platen 1 is moved to a position flush with the transport guide 2 by a drive mechanism (not shown). Then, the passbook 4 is transported in the direction of arrow A as shown in FIG.

At this time, the conveyance guide hole 2 of the conveyance guide 2
The front end or the rear end of the passbook 4 is guided in the direction of arrow A by the flat surface 2c around b. Thereby, the front end or the rear end of the passbook 4 is smoothly transported in the direction of arrow A without entering the transport guide hole 2b of the transport guide 2.

When the passbooks 4 have different thicknesses, the positions of the platen 1 and the print head 3 are controlled as follows.

FIG. 5 shows a case where the passbook 4 is thin. After the thickness of the passbook 4 is detected by a detection mechanism (not shown), a constant clearance t is maintained between the platen 1 and the print head 3.

In this case, when the front end or the rear end of the passbook 4 passes through the upper surface of the platen 1, the upper surface of the platen 1 having the taper 1a is moved to a position protruding from the transport guide hole 2b of the transport guide 2. At this time, the upper surface of the platen 1 is protruded to such an extent that the taper 1 a looks into the upper surface of the transport guide 2.

On the other hand, when the passbook 4 is thick, the positions of the platen 1 and the print head 3 are controlled as shown in FIG.

That is, the platen 1 and the print head 3
, A certain clearance t is maintained as described above. At this time, the upper surface of the platen 1 having the taper 1a is
Is moved to a position where it slightly protrudes.

In this case, as described above, when the leading end or the trailing end of the passbook 4 passes over the upper surface of the platen 1, the taper 1a
Is moved to a position slightly protruding from the conveyance guide hole 2b of the conveyance guide 2.

As described above, in the present embodiment, the transport guide 2 that transports the passbook 4 in a predetermined direction, and moves up and down in accordance with the thickness of the passbook 2 to keep the clearance t between the print head 3 and the passbook 4 constant. And a platen 1 for keeping
Has a transport guide hole 2b for passing through the upper surface of the platen 1.
And the leading or trailing end of the passbook 4 is guided by the flat surface 2c around the carrying guide hole 2b of the carrying guide, so that the leading or trailing end of the passbook 4 does not fit into the carrying guide hole 2b. The occurrence of jam can be prevented.

FIG. 7 is a sectional view showing an embodiment of the image reader of the present invention, FIG. 8 is a plan view showing the image reader of FIG. 7, FIG. 9 is a sectional view showing the image reader of FIG. FIG. 10 is a diagram for explaining the operation of the image reader of FIG.

As shown in FIGS. 7 to 9, the image reader has a backup plate 6. A taper 6b is provided on the upper surface of the backup plate 6 that is in contact with the paper sheet 5. The backup plate 6 is partially provided with a notch 6a. Thereby, the backup plate 6 is provided with a plurality of upper surfaces.

On the upper side of the backup plate 6, a transport guide 7 for guiding the transport of the paper sheets 5 is provided. The transport guide 7 is provided with a plurality of transport guide holes 7 b for projecting a plurality of upper surfaces of the backup plate 6. Each transport guide hole 7b is provided with a taper 7a inclined inward.

An image sensor 8 is arranged above the backup plate 6. The paper sheet 5 is transported in the direction of arrow A by the transport guide 7. Then, the backup plate 6 is moved up and down by a drive mechanism (not shown).

Next, the operation of the image reader having such a configuration will be described.

First, when the paper sheet 5 is conveyed in the direction of arrow A by the conveyance guide 7, the upper surface of the backup plate 6 has moved to a position flush with the conveyance guide 7 as shown in FIG.

At this time, even if the leading or trailing end of the paper sheet 5 approaches the carrying guide hole 7b of the carrying guide 7, the leading or trailing end of the paper sheet 5 is guided by the flat surface 7c of the carrying guide 7. . Therefore, the leading end or the trailing end of the paper sheet 5 does not enter the transport guide hole 7b of the transport guide 7 and the arrow A
It is transported smoothly in the direction.

On the other hand, when reading characters or the like of the paper sheet 5, the leading end or the rear end of the paper sheet 5 is
As shown in FIG. 10, the upper surface of the backup plate 6 is pushed out from the transport guide hole 7b. The pushing amount of the backup plate 6 at this time is
This is until the paper sheet 5 is located within the depth of focus of the image sensor 8.

Thus, the sheet 5 is read by the image sensor 8 while being conveyed in the direction of arrow A by the conveyance guide 7.

As described above, in the present embodiment, the paper sheets 5
And a backup plate 6 that moves up and down in accordance with the thickness of the paper sheet 5 and maintains a constant clearance between the image sensor 8 and the paper sheet 5. Is provided with a transport guide hole 7b through which the upper surface of the backup plate 6 passes, and the leading end or the rear end of the paper sheet 5 is provided at the transport guide hole 7b of the transport guide 7.
Is guided by the flat surface 7c around the paper sheet 5 so that the leading end or the trailing end of the paper sheet 5 does not fit into the conveyance guide hole 7b, so that the occurrence of a jam can be prevented.

[0034]

As described above, according to the passbook printer apparatus, the passbook transport method and the image reader according to the present invention, the transport guide for transporting the passbook or the sheet in a predetermined direction, and the thickness of the passbook or the sheet. A platen or backup plate that moves up and down according to the print head or image sensor and keeps a constant clearance between the passbook or paper sheet, and the transport guide has a transport guide hole that passes through the upper surface of the platen or backup plate. And guide the leading or trailing end of the passbook or paper sheet by a flat surface around the carrying guide hole of the carrying guide so that the leading or trailing end of the passbook or the bill does not fit into the carrying guide hole. Therefore, occurrence of a jam can be prevented.
