JPH05261985A - Inserting structure for machine-glazed paper in automatic printer - Google Patents

Abstract

PURPOSE:To make it possible to feed machine-glazed paper and set the sheet for printing by a single operation in an automatic printer and make the structure of it simple. CONSTITUTION:An automatic printer is constituted of a base casing main body 4 and a movable base casing 7 engaged with it by a hinge 5 in an openable/ closable way. In the printer, a machine-glazed paper cutter 8 is provided on a connection surface of the base casing main body 4 and the movable base casing 7, and also a command circuit 9 is provided for giving command for rotating a machine-glazed paper R1 reversely by a length, which ranges from a branch point Q of a passage P1 to a ticket issue port 10 of the machine-glazed paper R1 and a passage P2 to the machine-glazed paper cutter 8 until the cutter 8, to a drive roll 2 of the machine-glazed paper R1. After the machine-glazed paper R1 cut by the cutter 8 is returned automatically to the branch point Q, it is inserted automatically into the passage P1 for the ticket issue port 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper inserting structure in an automatic printing device, and more particularly to an improvement for easily supplying a roll paper in an automatic ticket issuing device or the like.

[0002]

2. Description of the Related Art As an automatic ticket issuing device for passing tickets or receipts on highways, a built-in roll paper is pulled out for a certain length, a predetermined character is printed on it, and then cut with a cutter. 2. Description of the Related Art An automatic ticket issuing device configured to deliver to an outlet is widely used.

Since roll paper is a consumable item in these automatic ticket issuing apparatuses, it is necessary to replenish the paper appropriately. As a structure for that purpose, a conventional automatic ticket issuing apparatus supports a roll paper R rotatably around an axis as shown in FIG. A receiving unit A1, a drive roll A2 for pulling out a certain length of paper from the roll paper R, a base frame main body A having a cutter unit A3 for cutting the drawn roll paper R1, and printing on the drawn roll paper. The roll paper R can be exchanged by engaging the movable base frame B having the head B1 so as to be openable and closable with, for example, a hinge C, and opening the movable base frame B as shown by a chain double-dashed line. ing. In the figure, D indicates the lid of the entire device.

[0004]

However, in the case of the above configuration, in order to set the roll paper R to be printable, the roll paper R
Need to be pulled out to an appropriate length through the drive roll A2 to the cutter part A3, but this gap is very narrow, and the roll paper R is thin and stiff, which makes the work considerably troublesome. If the paper breaks occur when it is crowded, there is a drawback that it takes too much time to replace the roll paper and causes congestion.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a roll paper insertion structure in an automatic printing apparatus which allows one-touch paper setting for roll paper supply and printing and has a simple structure. It was made for the purpose of doing.

[0006]

That is, a roll paper insertion structure in an automatic printing apparatus according to the present invention includes a receiving portion for supporting a roll paper so as to be rotatable around an axis, and a drive roll for drawing a paper of a certain length from the roll paper. A base frame main body having a cutter portion for cutting the drawn roll paper, a movable base frame engaged with the base frame main body so as to be openable and closable, and a head for printing on the drawn roll paper. In the automatic printing device, a roll paper cutting cutter is provided on the outer surface at the joint interface between the base frame body and the movable base frame, and the path to the ticket issuing port of the roll paper and the path to the roll paper cutting cutter are branched. A command circuit for giving a reverse rotation command to the drive roll of the roll paper is provided by the length from the point to the roll paper cutting cutter.

[0007]

Embodiments of the present invention will be described below. FIG. 1 is a sectional view of an embodiment of the present invention, FIG. 2 is an enlarged sectional view of an essential part of the embodiment, and FIG. 3 is an enlarged perspective view of an essential part of the embodiment.

The roll paper insertion structure in the automatic printing apparatus of the present invention comprises a receiving portion 1 for supporting the roll paper R rotatably around the axis, a drive roll 2 for pulling a certain length of paper from the roll paper, and a pulled roll. A base frame main body 4 having a cutter unit 3 for feeding the paper R1 to the roll paper guide 3A and further cutting it with the rotary blade 3A and the fixed blade 3B, and the base frame main body 4
On the other hand, in an automatic printing apparatus including a movable base frame 7 that is openably and closably engaged with a hinge 5 and the like, and a head 6 that prints on the drawn roll paper R1, as shown in an enlarged view in FIG. , A joint interface S between the base frame body 4 and the movable base frame 7
Is provided with a roll paper cutting cutter 8 and roll paper R1
A command circuit for giving a reverse rotation command to the drive roll 2 of the roll paper R1 by the length from the branch point Q of the path P1 to the ticket issuing slot 10 and the path P2 to the roll paper cutting cutter 8 to the roll paper cutting cutter 8 And 9 are provided.

In the above embodiment, the roll paper cutting cutter 8 may be provided on either the base frame body 4 side or the movable base frame 7 side, and in the case of the embodiment, the roll paper cutting cutter 8 is provided on the movable base frame side.
In addition, 11 indicates a lid of the entire apparatus.

[0010]

In the present invention, when it becomes necessary to replenish the roll paper R, the movable base frame 7 is opened and the roll paper receiving portion 1 is opened as shown by the chain double-dashed line in FIG. Then, the roll paper R is replenished, and its end is pulled out to the roll paper cutting cutter 8 on the outer surface of the base frame. After that, the movable base frame 7
When is closed, the roll paper R1 extends between the drive roll 2 and the cutter 8 as shown in FIG.

When the roll paper R1 is cut by the cutter 8 and the command circuit 9 is operated, the drive roll 2 rotates in the reverse direction and the path P
The roll paper R1 is pulled back to the branch point Q of 1 and P2, and the end is aligned with the branch point Q and stopped.

Next, by driving an attached ticket issuing test circuit (not shown) or the like to feed the paper in a normal state, the roll paper R
1 is guided by the roll paper guide 3A and automatically sent to the path P1 toward the print head 6, and the paper is automatically set.

[0013]

As described above, according to the roll paper inserting structure in the automatic printing apparatus of the present invention, after the roll paper is replenished in the receiving portion, it is not necessary to pass through narrow paper guide rolls or cutters. By simply sandwiching the roll paper between the base frame body and the movable base frame and closing it, the roll paper will be automatically set to the regular path only by the reverse rotation forward rotation drive of the drive roll. It is greatly simplified. Further, when implementing the apparatus of the present invention, since it is sufficient to provide the roll paper cutting cutter 8 and the reverse rotation instruction circuit 9 in the conventional automatic ticket issuing apparatus and the like, there are various effects such as easy implementation.
