본 고안은 바코드리더의 구동장치에 관한 것으로, 특히 팬과 홀로그램 디스크를 1개의 모터로 일체로 연결하여 소형, 경량화에 도움을 주고자 안출한 것이다.The present invention relates to a driving device of a barcode reader, and in particular, to provide a compact and lightweight by connecting the fan and the hologram disk integrally with one motor.
종래의 바코드리더(Bar Code Reader)에는 제1도와 같이 모터(6)와 팬(8)이 각각 광학부와 회로부에 별개로 설치되어 있다.In the conventional bar code reader, the motor 6 and the fan 8 are separately provided in the optical section and the circuit section, respectively, as shown in FIG.
상기 모터(6)는 패턴을 형성하기 위한 홀로그램 디스크를 장착하여, 광학부에서 독립적으로 구동되고, 팬(8)은 회로부의 하부에 위치하여 회로의 냉각기능을 수행하도록 되어 있다.The motor 6 is equipped with a hologram disk for forming a pattern, and is driven independently by the optical part, and the fan 8 is located under the circuit part to perform a cooling function of the circuit.
따라서, 바코드리더의 주파워 공급장치에 의해 팬(8)과 모터(6)를 각각 독립적으로 구동되고, 이때 모터(6)는 홀로그램 디스크를 구동시켜 패턴을 발생시키고, 팬(8)은 또다른 파워라인을 통해 동력을 공급받아 회로부를 냉각하는 기능을 수행한다.Therefore, the fan 8 and the motor 6 are driven independently by the main power supply of the barcode reader, where the motor 6 drives the hologram disk to generate a pattern, and the fan 8 is another. Power is supplied through the power line to cool the circuit.
즉, 광학부와 회로부는 서로 분리되어 공기 흡입구와 배출구를 형성하여 공기의 흐름이 회로부 내부에서 이루어질 수 있도록 되어 있다.That is, the optical unit and the circuit unit are separated from each other to form an air inlet and an outlet so that the air flows in the circuit unit.
따라서 팬(8)은 항상 회로부에 있어야 하며 모터(6)는 광학부내에 위치하고 있으므로 동력공급이 이원화되고, 팬(8)과 모터(6)의 최소 설치공간을 확보하여야만 되기 때문에 소형, 경량화에는 어려움이 따르고, 팬과 모터의 설치위치가 제한되기 때문에 필요없는 부분에 빈공간을 남겨두어야 하는 결점이 있었다.Therefore, the fan 8 must always be in the circuit part, and since the motor 6 is located in the optical part, power supply is dualized, and the minimum installation space of the fan 8 and the motor 6 must be secured. As a result, the fan and motor installation positions are limited, so there is a drawback to leaving empty space in unnecessary parts.
본 고안은 이러한 종래의 결점을 해결하고자 안출한 것으로, 모터의 축을 양측으로 돌출시켜 팬과 홀로그램 디스크를 각각 고정 설치하고, 팬은 회로부에, 홀로그램 디스크는 광학부에 위치되게 차단벽으로 구분하는 동시에 팬에 의해 유입되는 공기를 회로부로 유도하도록 유체 유도용 격벽을 설치한 것으로 바코드리더의 소형, 경량화에 도움을 줄 수 있는 것이다.The present invention has been devised to solve the above-mentioned shortcomings. The fan and the hologram disk are fixed and installed by protruding the shafts of the motor to both sides, and the fan is divided into the blocking wall so that the fan is located in the circuit and the hologram disk in the optical part. A fluid induction partition is installed to guide the air introduced by the fan to the circuit part, which can help to reduce the size and weight of the barcode reader.
이하 본 고안을 첨부도면에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도면 제2도 및 제3도에서 본체(1) 내부의 일측 중간부에 차단벽(2)을 설치하여 회로부와 광학부를 구분하고, 회로부측에 유체 유도용 격벽(3)을 형성하여 공기흡입구(4) 및 배출구(5)와 연통되게 한다.2 and 3, a blocking wall 2 is provided at one intermediate part inside the main body 1 to separate the circuit part from the optical part, and a partition 3 for inducing fluid is formed on the circuit part side to form an air suction port ( 4) and the outlet (5).
그리고, 모터(6)의 축(7)을 양측으로 돌출시켜 상단에는 팬(8)을, 하단에는 홀로그램 디스크(9)를 각각 고정 설치한 후 팬(8)은 회로부측에, 홀로그램 디스큼(9)는 광학부측에 위치되게 모터(6)를 차단벽(2)에 나사(10)로 고정 설치한다.Then, the shaft 7 of the motor 6 protrudes to both sides, and the fan 8 is fixed at the upper end and the hologram disk 9 is fixed at the lower end, respectively, and the fan 8 is placed on the circuit part side. 9), the motor 6 is fixed to the blocking wall 2 with a screw 10 so as to be located at the optical part side.
즉, 상술한 장치는 1개의 모터(6)로 팬(8)과 홀로그램 디스크(9)를 동시에 구동시킴으로써 바로크 스캐너의 소형, 경량화에 기어하면서 종래의 스캐너가 가지고 있는 성능과 동일한 효과를 유지하게 되는 것이다.In other words, the above-described apparatus drives the fan 8 and the hologram disk 9 simultaneously with one motor 6, thereby maintaining the same effect as that of the conventional scanner while gearing up for the compact and lightweight baroque scanner. will be.
또, 광학부품이 장착되는 곳과 회로기판이 설치되는 곳이 차단벽(2)에 의해 각각 구분되어 있어 모터(6)의 구동시 팬(8)과 홀로그램 디스크(9)의 기능을 각각 발휘하도록 하는 것이다.In addition, the place where the optical component is mounted and the place where the circuit board is installed are separated by the blocking wall 2 so that the functions of the fan 8 and the hologram disk 9 can be exhibited respectively when the motor 6 is driven. It is.
이때 팬(8)의 회전수는 홀로그램 디스크(9)의 요구되는 회전수에 종속적으로 회전하게 되고, 유체의 흐름은 공기 흡입구(4)를 통해 공기가 유입되어 유체유도용 격벽(3)을 따라 유도되고, 유도된 공기는 파워 서플라이를 포함한 회로부측으로 흐르게 되어 회로부에 필요한 냉각기능을 수행하게 되는 것이다.At this time, the number of revolutions of the fan 8 is rotated in dependence on the required number of revolutions of the hologram disk 9, and the flow of fluid flows through the air inlet 4 and along the fluid guide partition 3. The induced and induced air flows to the circuit part side including the power supply to perform the cooling function required for the circuit part.
즉, 제3도와 같이 모터(6)가 구동하게 되면 홀로그램 디스크(9)는 광학부에서, 팬(8)은 대기중의 공기를 흡입하여 공기흡입구(4)를 통해 유체유도용 격벽(3)을 유도시키고, 유도되는 공기는 회로기판이 설치된 곳으로 흐르면서 냉각기능을 수행하고 냉각기능을 마친 공기는 공기배출구(5)를 통해 대기중으로 배출되는 것이다.That is, when the motor 6 is driven as shown in FIG. 3, the hologram disk 9 is sucked by the optical unit, and the fan 8 sucks air in the air, and the fluid induction partition 3 is formed through the air inlet 4. The induced air flows to the place where the circuit board is installed to perform a cooling function, and the finished air is discharged into the atmosphere through the air outlet (5).
이때 회로부와 광학부는 완전히 분리되어 있어 광학부품에는 영향을 미치지 않게 된다.At this time, the circuit part and the optical part are completely separated so that the optical part is not affected.
이와같이 본 고안은 팬과 홀로그램 디스크를 1개의 모터로 일체화시켜 공간을 최소한 줄일 수가 있어 소형, 경량화에 도움을 줄 수 있을 뿐만 아니라 원가인하에도 도움을 줄 수 있는 것이다.As such, the present invention integrates the fan and the hologram disk into one motor, thereby reducing the space at least, which can help to reduce the size and weight as well as the cost.
