The present invention relates to a coupling structure of an encoder sensor installed in the printer of a cash register to control the alignment of the vertical factors by the print head. In particular, the sensor substrate on which the uncoder sensor is integrally coupled is formed on the main frame. The guide piece is bent in the guide piece and the screw is fixed to be coupled, the disc-shaped encoder (Encoder) is installed between the uncoder sensor, the fixed shaft is inserted into the lead cam coupling hole of the main frame, the coupling of the uncoder sensor It is not necessary to install a separate bracket at the time, making it easy to manufacture and install, and the uncoder sensor of the cash register printer that allows the uncoder sensor to be fixed at the correct position to maintain the vertical printing alignment by the print head accurately. To a bonding structure.

In general, a print head which prints a slip and a receipt while transferring to the left and right by a lead cam that is stolen by a printer of a cash register is controlled by an uncoder sensor installed at one side and performs printing while aligning the vertical printing.

In the coupling structure of a conventional uncoder sensor related to this technology, as shown in FIG. 1, the uncoder fixing bracket 22 is fixed to one side of the printer mainframe 21 as a screw 23, The guide plate 24 is bent to one side of the rear side of the uncoder fixing bracket 22 so that the uncoder sensor 26 coupled to the sensor substrate 25 can be coupled and installed as a screw 27. The fixed shaft 30 of the uncoder 29 is inserted into the coupling hole 28 at the center of the fixing bracket 22 to be inserted into the lead cam coupling hole 31 of the main frame 21.

In the conventional uncoiled sensor coupling structure having the above structure, a separate uncoated fixing bracket 22 is installed on one side of the main frame 21 of the printer, and the uncoiled sensor 26 is provided on one side of the guide plate 24. By installing the combined sensor substrate 25, manufacturing and assembly is cumbersome, and workability due to installation of manufacturing parts of many parts is reduced, as well as a disc-shaped uncoder coupled between the uncoder sensors 25 ( 29 is inserted into the coupling groove 28 and the lead cam coupling groove 28 of the uncoder fixing bracket 22 so that the position of the uncoder sensor 26 cannot be maintained accurately, so that the vertical factor is not aligned. There were many problems.

The present invention has been made in order to improve the conventional problems as described above, the object of the above, the sensor substrate to which the uncoder sensor is integrally coupled to be fixed as a guide piece and screw formed bent on the main frame, The disc-shaped uncoder installed between the uncoder sensors has a fixed shaft inserted into the lead cam coupling hole of the main frame so that a separate bracket does not need to be installed when the uncoder sensor is coupled, making it easy to install a manufacturing tool. It is to provide an uncoiler sensor coupling structure of the cash register printer that can be fixed to the correct position in the encoder position to maintain the vertical print alignment by the print head.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is an exploded perspective view of the main part for explaining the uncoder sensor coupling structure of the printer according to the present invention, the guide piece (3) is bent in the rear side of the main frame (1) where the lead cam coupling hole (2) is installed And the uncoder sensor 5 coupled to the sensor substrate 4 to be fixedly coupled to the guide piece 3 as a screw 6, and the uncoder 7 coupled and fixed between the uncoder sensors 5. The fixed shaft 8 is made of a structure that is fixed to be inserted into the lead cam coupling groove 2 of the main frame (1).

Referring to the operation and effects of the present invention composed of such a structure as follows.

That is, as shown in FIG. 2, when the uncoder 7 and the uncoder sensor 5 are coupled to one side of the main frame 1 of the printer, first, the lead cam coupling hole provided in the main frame 1 2) The fixed encoder 8 of the uncoder 7 is inserted into the uncoder 7 to fix the uncoder 7, and then the uncoder sensor 5 is placed on the upper side of the guide piece 3 which is bent behind the main frame 1. ) Is attached and fixed to the sensor substrate 4 provided with the screw 6.

At this time, the position of the encoder sensor 5 is uncoded by adjusting the position on one side of the main frame 1 in advance so that the encoder encoder 5 is installed behind the encoder 7 fixedly installed. It can be adjusted precisely according to the, and can be easily installed by the uncoder 7 and the uncoder sensor 5 by a simple structure.

According to the uncoiler sensor coupling structure of the printer according to the present invention as described above, there is no need to install a separate bracket frame when the uncoder sensor is coupled, so that the manufacture and installation of the uncoiler sensor is easy, so that the uncoder sensor is fixed in the correct position There is an effect that can maintain the vertical print alignment by the print head accurately.
