Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus for printing characters and images on an arbitrary form, and more particularly to a form drop prevention mechanism for preventing a form from falling at a form inlet / outlet.

[0002]

2. Description of the Related Art Conventionally, there is no form drop prevention mechanism for preventing a form discharged from a passbook printer from falling, and a countermeasure is taken by widening a table surface.

[0003]

As described above, it is difficult to widen the table surface in the recent trend of miniaturization of the device size, and the form discharged from the passbook printer falls from the table surface. In some cases, which is very inconvenient for the user of the passbook printer.

Accordingly, an object of the present invention is to provide a form drop prevention mechanism capable of preventing a form from falling in order to solve the above-mentioned problem.

[0005]

In order to achieve the above object, a form drop prevention mechanism according to the present invention is provided in a passbook printer having a table for inserting and discharging forms, and a transport roller for sending out forms. In the form fall prevention mechanism provided, it is provided at the leading end for inserting and discharging the form on the table, and is formed on almost the same surface as the table surface, and is used for sending the form.
By providing a movable stack having a structure in which the front side is lifted , the form is prevented from falling.

It is preferable that the form fall prevention member has a friction member having a large frictional force with the form.

Further, it is preferable that the friction member is provided in an L-shape at the corner of the tip of the table.

Furthermore, it is preferable that the friction members are arranged near both ends in the width direction of the form.

In addition, the form fall prevention member may have a rectangular stack portion in which one side close to the front end of the table can be erected from the surface of the table, and a side opposite to one side close to the front end of the table is fixed. It is preferable to hook the report on one side near the tip of the document.

[0010] It is preferable that the stack portion is arranged near the center in the width direction of the form.

Further, when a plurality of forms are to be continuously processed, it is preferable to provide a jump table which is provided in the vicinity of the transport roller and stacks a post-processing form on a pre-processing form.

The form drop prevention mechanism of the present invention particularly has a movable stack at the end of a table for inserting and discharging a form of a passbook printer, and a friction member coated outside the stack. The stack mechanism has a stack section provided at the tip of the table, and a jump table provided near the transport roller.

[0013] The stack section is formed on the substantially same surface as the table surface, and has a structure in which the front side for sending the form by manual operation is lifted.

[0014]

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

FIG. 1 is a plan view showing an embodiment of a form drop prevention mechanism according to the present invention. As shown in the drawing, the passbook printer 1 includes a form drop prevention member provided only at the leading end of the table 4 for inserting and discharging forms. The form drop prevention member includes a stack portion 6 provided at the tip of the table 4 and two friction members 7 provided on both sides of the stack portion 6.

FIG. 2 is a side view showing an embodiment of a form drop prevention mechanism according to the present invention. The passbook printer 1 is provided with a first inserter 2 and a second inserter 3 for inserting and discharging forms. The second inserter 3 has a transport roller 5 at the back of the table 4, and the transport roller 5 inserts and ejects a form with the form interposed.

FIG. 3 is a sectional view taken along line AA ′ of FIG. 1 and shows the friction members 7 provided on both sides of the stack portion 6.
The friction member 7 is a friction member 7 having a large frictional force with the form, and prevents the form 8 from dropping by the frictional force. Also,
The friction member 7 is provided in an L-shape at the corner of the tip of the table 4. Further, the friction member 7 may be coated.

FIG. 4 is a cross-sectional view taken along the line BB ′ of FIG. 1 and shows the stack portion 6 provided at the tip of the table 4. The stack part 6 is a rectangular stack part 6 in which the form fall prevention member can stand up with one side near the tip of the table 4 away from the surface of the table 4 and fixed on the side facing the one side near the tip of the table 4. Then, the form 10 is hooked on one side close to the tip of the table 4. In addition, this figure shows a jump table 9 that is effective when a plurality of forms are continuously processed. The jump table 9 is provided near the transport roller 5, and stacks a post-processing form 11 on a form pre-processing form 10.

Next, the operation of the embodiment of the form drop prevention mechanism of the present invention will be described. First, the stacking unit 6 can be manually operated when the stacking function is required, and can discharge the form drawn from the first inserter 2 and printed to the second inserter 3 to be stacked. 1st inserter 2, 2nd
After the printing is completed, the form sucked from the inserter 3 is discharged to a position just before the conveying roller 5 by the conveying roller 5 of the second inserter 3. Here, in the case of the single process of printing the form once, it is possible to prevent the form 8 discharged from dropping due to the resistance of the friction member 7 provided outside the stack unit 6. In the case of continuous processing for printing a plurality of forms, as shown in FIG. 4, a post-processing form 11 is stacked on a pre-processing form 10 by a jump table 9 provided near a roller 5, and The end of the stack unit 6 is raised and the leading end of the form is lifted. In this way, the form can be prevented from falling.

[0020]

As described above, according to the present invention, it is possible to prevent an ejected form from falling even when a sufficiently large table surface cannot be secured due to restrictions on the size of the apparatus. .

Further, by using the stack unit, even when a plurality of forms are continuously processed, there is an effect that continuous processing can be performed without removing the forms one by one.
