The present invention relates to a jam removing structure and a printer module, and more particularly, to a printer module having a jam removing structure and a jam removing structure of a printing paper.

The jam of the printing paper refers to a phenomenon in which the printing paper is wrinkled in the process of printing and stagnated without moving along the moving path. If a jam of the printing paper occurs, printing cannot be performed inside the printer, and if the jam is severe, the device itself causes a failure.

In recent years, various types of printers such as a copy machine, an automated teller machine, a specification printer, and the like are widely used, and the printing jobs of such machines are also causing many failures due to jams of printing paper.

Conventional printers are equipped with a jam detection sensor therein to transmit a detection signal to the control unit when the jam of the printing paper occurs to stop printing. Therefore, the jam can be prevented from being severed by the jam detection sensor, and the printer can be prevented from malfunctioning, but the efficiency is lowered because a plurality of sensors must be mounted. In addition, when the crumpled printing paper is removed, it is difficult to insert into the machine parts and remove the paper. If the jam of the printing paper is severe and occurs inside the module, the printer may fail.

Accordingly, one object of the present invention for solving the above problems of the present invention is to provide a jam removing cover and a printer module for inducing jams to be concentrated in the lower space of the jam removing cover by mounting the jam removing cover. .

Another object of the present invention is to provide a jam removing cover and a printer module that can easily remove crumpled printing paper by an adjacent cutout.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the jam removing structure includes a guide portion and a jam removing cover.

The guide portion is a printing paper guide for printing, and thus, the jam removing structure may include a plurality of guide portions designed in a desired direction. An opening for discharging the printing paper is formed to guide the printing paper. The jam removing cover is rotatably mounted within a predetermined angle range at one end of the opening. Therefore, when the jam of printing paper occurs, the jam removing cover is separated from the guide part, provides a predetermined space from the guide part, and guides the jam into the space. Therefore, the jam removal cover is structurally mounted without using the electrical structure to remove the jam therein. However, in another embodiment of the present invention, the jam removing cover may be installed at a portion where jams other than the guide portion are frequently generated according to a designer's intention.

Conventionally, a jam detection sensor is mounted along a path of printing paper to remove jams. Therefore, the jam detection sensor detects the jam of the printing paper and transmits the detection signal to the control unit, and automatically stops printing by the command of the control unit in the following process. However, this process is inefficient and inexpensive because a plurality of jam detection sensors must be mounted at distances smaller than the paper length. In addition, jam-producing printing paper may be difficult to remove by pinching the internal parts. However, in the jam removing structure according to the present invention, since the jam of the printing paper is concentrated in the space generated by the jam removing cover, the jam is hardly generated inside the module, and the experimental results significantly reduce the occurrence of the failure so that there is almost no failure rate. Can be. In addition, since the jam removing cover is structurally mounted, the design is easy and the cost is not saved because a plurality of sensors do not need to be mounted.

Further, according to a preferred embodiment of the present invention for achieving the above object of the present invention, the printer module is provided with a print portion, a guide portion, a transfer roller and a jam removing cover.

The print portion is mounted to the housing and attached to the end of the guide portion to print a predetermined mark on the printing paper. Then, the guide unit transfers the printing paper from the printing unit and discharges the printing paper out of the housing. Then, the conveying roller is formed at the end of the guide portion and in contact with the lower portion of the printing paper, rotated by the driving force to move the printing paper in one direction. And, the jam removing cover is interposed between the transfer roller and the print module, and formed on the upper portion of the guide portion, and when jams of printing paper occur in the guide portion, the other portion is rotated to the upper portion of the guide portion with one side as the rotation axis. Rotate by an angle. In addition, a cutout may be formed in the print to cut the print paper having jammed therein. Therefore, even if a jam occurs, the printing paper is more convenient than the conventional one because it can be used by cutting the printing paper.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

Example 1

1 is a perspective view for explaining a jam removing structure according to a first embodiment of the present invention, Figure 2 is a side view for explaining a jam removing structure according to the first embodiment.

1 and 2, the jam removing structure includes a guide part 110 and a jam removing cover 120.

The guide part 110 is located adjacent to the print part, and includes an opening for transferring printing paper, and discharges the printing paper to the outside of the main body through the opening. The guide part 110 has both sides fixed to the frame 10. Then, the roller 112 is mounted on the surface of the guide portion 110, the roller 112 rotates by the rotational force transmitted from the power unit. At this time, the central axis penetrating the center of the roller 112 is rotated in connection with the power unit, and through this process the roller 112 is also rotated. However, in another embodiment of the present invention, a plurality of guide parts may be formed according to a designer's intention.

Jam removal cover 120 is located adjacent to the guide portion 110, when the jam of the printing paper occurs as the opening of the guide portion 110, the other side is separated from the guide portion 110 by using one side as the rotation axis Rotate by a predetermined angle. At this time, in this embodiment, the guide portion rotates toward the upper side, but the direction may rotate to the upper, lower, left and right. The jam removing cover 120 includes a cover plate 122 and a torsion spring 124. The cover plate 122 may be formed in the shape of a plate and may be interposed between the inside of the module and the roller 112. Therefore, one corner of the cover plate 122 is mounted to the guide unit 110 by the hinge 126, the edge adjacent to the inside of the module can be rotated by a predetermined angle toward the top. In the present embodiment, the cover plate 122 may rotate toward the upper portion of the guide portion 110 by about 30 degrees, but in another embodiment of the present invention, the rotation angle may be variously set according to the intention of the designer. The torsion spring 124 is mounted to the hinge 126, one end is in contact with the upper surface of the guide portion 110, the other end is in contact with the cover plate 122, and forms a constant angle between both ends. Therefore, when the cover plate 122 moves toward the upper portion of the guide portion 110, both ends of the torsion spring 124 are opened in a direction away from each other, and the elastic force is transmitted to the cover plate 122, and the cover plate 122 is When the force is removed is automatically moved toward the lower portion of the guide portion (110). Therefore, the jam enters the lower space of the cover plate 122 on the printing paper, and the cover plate 122 presses the upper portion of the printing paper. Therefore, when the jam of the printing paper becomes severe, the printing paper is prevented from pushing out of the cover plate 122 out of the space, and the jam of the printing paper is concentrated on the lower portion of the cover plate 122. Jam removal cover 120 may be mounted adjacent to the opening of the guide portion, it may be mounted to the frequently jam.

3 and 4, the jam removing cover 120 is formed on the upper portion of the guide portion 110, the roller 112 is mounted on the guide portion 110 to move the printing paper in the advancing direction. The jam removing cover 120 is disposed between the inner module M and the roller 112. Therefore, when the printing paper P is discharged to the outlet via the roller 112, but jam occurs in the printing paper P inside the module, the cover plate 122 rises toward the upper portion of the guide part 110, and A space is formed between them. However, in another embodiment of the present invention, the cover plate may move toward the lower side and the side according to the intention of the designer. Accordingly, the jam of the printing paper P is discharged into the space, and the cover plate 122 moves upward to accommodate the jam (ⓐ). Then, when the printing paper due to the jam is removed, the cover plate 122 is moved to the original position by the torsion spring 124. Therefore, the jam of the printing paper P is concentrated in the space generated by the jam removing cover 120 so that no jam is generated inside the module, and the failure rate is close to zero and can be reduced. In addition, the jam removing cover 120 is structurally easy to be mounted on the device, it is not necessary to mount a plurality of sensors as in the prior art can be saved manufacturing costs.

5 and 6, the printer module includes a guide part 210, a jam removing cover 220, a transfer roller 230, and a print part 240.

The printing unit 240 is mounted on the housing to print a predetermined mark on the printing paper. The print unit 240 uses a thermal print head 242 capable of printing a predetermined mark by applying heat to the thermal paper, and the platen 244 in contact with the thermal print head 242 to support and transport the print paper. It includes. However, in other embodiments of the present invention, various printing methods may be used according to the designer's intention. Then, the cutter 246 is mounted adjacent to the print unit 240 to cut the printed paper and move toward the guide portion 210. In addition, the print unit 240 has a sawtooth cutout portion 248 is formed on the outer surface of the outlet from which the printing paper is discharged. Therefore, when the jammed printing paper is removed after contacting the cutout 248, the damaged printing paper can be easily removed. However, the cutout portion may be mounted adjacent to the opening through which the printing paper is discharged, and may be mounted on the guide portion, the print portion, and the main body.

 The guide unit 210 is disposed adjacent to the print unit 240 and serves to guide the printing paper to the discharge port. Both sides of the guide part 210 may be fixed to the frame. However, in another embodiment of the present invention, a plurality of feed rollers may be formed according to the intention of the designer.

The feed roller 230 is formed in the guide portion 210, and rotates the central axis penetrating the center of the roller by the power transmitted from the power unit, and the feed roller 230 also rotates through this process. However, in another embodiment of the present invention, a plurality of feed rollers may be formed according to the intention of the designer.

The jam removing cover 220 is interposed between the transfer roller 230 and the print unit 240. The jam removing cover 220 includes a cover plate 222 and a torsion spring 224. Cover plate 222 is formed in the shape of a plate, one end is connected to the guide portion 210 by a hinge, the other end is bent to face upward. Therefore, when jam occurs in the printing paper, the cover plate 222 automatically rotates the hinge upwards on the axis. Then, the torsion spring 224 is mounted by the hinge 226, one end is in contact with the upper surface of the guide portion 210, the other end is in contact with the upper surface of the cover plate 222. Therefore, when the cover plate 222 moves toward the upper portion of the guide portion 210, both ends of the torsion spring 224 are opened to provide elastic force to the cover plate 222, the elastic force 222 is the original force when the external force is removed It moves toward the bottom of the guide portion 210 which is the position of. Therefore, the torsion spring 224 serves to press the guide portion 210 and the cover plate 222. However, in another embodiment of the present invention, the torsion spring may be replaced with various elastic members according to a designer's intention.

Then, the paper recovery portion is in close contact with one end of the guide portion 210, when the roller 230 is rotated in the opposite direction to the traveling direction, the printing paper is automatically moved and recovered to the paper recovery portion. In this way, it is possible to recover the printing paper that has not been drawn out, thereby preventing jams of the printing paper that may occur at the exit.

Therefore, the printer module can be automatically removed by the jam removing cover 220 when a jam occurs in the printing paper, thereby avoiding a failure of the printer module. In addition, since the printing paper having jammed in the space generated by the movement of the cover plate 222 can be easily removed by the cutout 248, the jam can be easily removed than before.

Therefore, the jam removing structure concentrates the space of the jam of the printing paper by the jam removing cover, so that the jam is hardly generated inside the module of the device, thereby reducing the failure rate. In addition, the jam removing cover is structurally easy to be mounted on the device, it is not necessary to mount a plurality of sensors as in the prior art can reduce the manufacturing cost.

In addition, the printer module can be automatically removed by the jam removing cover when the jam occurs on the printing paper to reduce the failure rate of the printer module, the cutout can be formed adjacent to the cover plate, it is wrinkled in the lower space of the cover plate Since the printing paper can be easily removed, it is easier to remove the printing paper than before.
