본 발명은 VCR의 도어로크장치에 관한 것으로, 테이프 추출동작시 개방되어지는 도어에 손을 넣을 경우 테이프 추출동작을 중지시켜 손가락의 손상을 방지하는 것이다.The present invention relates to a door lock device of a VCR, and stops the tape extraction operation when the hand is put into the door that is opened during the tape extraction operation to prevent damage to the finger.
VCR에서 테이프를 추출하고 삽입할 때 개폐되어지는 도어에 손가락이 끼게되는 경우가 발생되고 이 경우 손가락을 다칠 우려와 함께 도어가 망가지는 문제점이 발생되며, 특히 테이프가 삽입되어 있는 상태에서 도어를 열고 손을 밀어 넣은 상태로 테이프를 추출시키는 동작을 수행시키게 되면 손가락을 다치게 되는 문제점이 있게 된다.When extracting and inserting a tape from the VCR, a finger may be caught in the door to be opened and closed. In this case, a finger may be damaged and the door may be broken. In particular, when the tape is inserted, the door is opened. If you perform the operation of extracting the tape while pushing the hand, there is a problem that the finger is injured.
따라서 기존에는 덱크에 별도의 기구적 도어 로크 장치를 설치하여 테이프가 VCR 내부에 삽입된 상태에서는 상기 도어록크 장치를 작동시켜 도어를 로크시킴으로써 테이프가 VCR 내부에 장착된 상태에서는 도어가 열리지 않아 테이프 추출시 손가락을 다치게 되는 경우를 없애주도록 하고 있다.Therefore, in the past, a separate mechanical door lock device was installed on the deck to operate the door lock device when the tape was inserted into the VCR to lock the door, so that the door did not open when the tape was mounted inside the VCR. Do not get hurt if your finger hurts.
상기 도어로크장치는 VCR 도어의 일측을 걸어주는 기구적 레버를 VCR 하우징에 설치한 후 테이프 삽입시는 상기 기구적 레버를 테이프가 밀어 도어를 로크시킴으로써 테이프가 삽입된 상태에서 도어가 열리지 않도록 하고, 테이프 추출동작시는 상기 기구적 레버가 원위치되면서 도어로크상태를 해제시킴으로써 도어가 열리면서 테이프가 추출되도록 되어 있다.The door lock device is installed in the VCR housing a mechanical lever that hangs on one side of the VCR door, and when the tape is inserted, by pushing the mechanical lever to lock the door so that the door does not open while the tape is inserted, During the tape extraction operation, the door is opened and the tape is extracted by releasing the door lock state while the mechanical lever is in the original position.
따라서 테이프 삽입시에는 도어로크 장치의 기구적 레버에 의해 도어의 일측을 로크시키게 되나 기구적으로 도어의 일측만 로크시키게 되고 타측은 로크시키지 못하게 되므로, 도어의 타측을 강제로 밀 경우 도어로크가 해제되는 경우가 발생되는 한편 무리한 힘을 가했을 때 도어 또는 도어로크장치의 기구적 레버가 파손되는 문제점이 있게 된다.Therefore, when the tape is inserted, one side of the door is locked by the mechanical lever of the door lock device, but only one side of the door is mechanically locked and the other side cannot be locked. Therefore, when the other side of the door is forcibly pushed, the door lock is released. In the meantime, the mechanical lever of the door or the door lock device is damaged when excessive force is applied.
본 발명은 상기된 도어로크장치를 사용하지 않고 센서를 이용하여 VCR 도어개폐여부를 감지하고 이에 따라 도어개방되어 있을 때는 테이프 추출동작이 이루어지지 않도록 하므로써 도어가 개방된 상태인데도 테이프 추출동작이 진행되어 도어가 파손되거나 손가락이 부상당하는 위험을 없앤 것이다.The present invention detects whether the VCR door is opened or closed by using a sensor without using the door lock device described above, and thus the tape extraction operation is performed even though the door is opened by preventing the tape extraction operation when the door is opened. It eliminates the risk of door breakage or finger injury.
이러한 본 발명은 도어의 열리고 닫힘을 감지하는 센서와, 도어 배면부에 형성되어 도어개방시 센서를 동작시키는 보호구와, 도어센서 출력을 인식하여 도어개방상태에서는 테이프 추출동작을 정지시키는 마이콤으로 이루어지며, 도어개방시 도어 배면에 형성된 보호구에 의해 센서에서 도어개방을 감지한 센서출력을 마이콤에 인식시키고 마이콤에서는 도어가 개방되었음이 인식되면 테이프 추출키가 눌리더라도 추출동작을 수행시키지 않게 되는 것으로 도어가 닫혀 있는 상태에서만 테이프 추출동작이 수행되도록 하는 것이다.The present invention consists of a sensor for detecting the opening and closing of the door, a protective device formed on the rear surface of the door to operate the sensor when the door is opened, and the microcomputer to stop the tape extraction operation in the door open state by recognizing the door sensor output, When the door is opened, the protective device formed on the back of the door recognizes the sensor output when the sensor detects the opening of the door, and the micom recognizes that the door is open.It does not perform the extraction operation even if the tape extraction key is pressed. The tape ejection operation is performed only in the closed state.
이하 본 발명을 첨부도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
VCR의 도어(10) 배면부에는 빛을 차단하는 보호구(20)를 형성시키고, 상기 도어(10)가 개방된 상태에서 발광다이오드(40)의 빛이 보호구(20)에 의해 센서(30)에 전달되는 것이 차단될 수 있도록 도어(10)의 양측 하우징에 센서(30)와 발광다이오드(40)를 설치하며, 상기 센서(30)의 검출출력은 마이콤(50)에서 인식하여 테이프 추출동작을 제어하도록 구성된다.On the back of the door 10 of the VCR is formed a protective device 20 to block light, and the light of the light emitting diode 40 is transmitted to the sensor 30 by the protective device 20 in the state in which the door 10 is open. The sensor 30 and the light emitting diode 40 are installed in both housings of the door 10 so as to be blocked, and the detection output of the sensor 30 is recognized by the microcomputer 50 to control the tape extraction operation. It is composed.
여기서 센서(30)는 발광다이오드(40)에서 발생된 빛을 검출하는 소자로써 도어(20)가 고정된 하우징의 상부 양측에 대향된 위치로 설치되어, 도어(10)닫힘시는 발광다이오드(40)의 빛이 센서(30)로 인가되고, 도어(10)개방시는 도어(10)배면의 보호구(20)가 발광다이오드(40)와 센서(30)사이에 위치되어 발광다이오드(40)의 빛이 센서(30)로 인가되지 않게 한다.Here, the sensor 30 is a device for detecting the light generated by the light emitting diodes 40 and is installed at positions opposite to both sides of the upper part of the housing in which the door 20 is fixed, and the light emitting diodes 40 when the door 10 is closed. ) Is applied to the sensor 30, and when the door 10 is opened, a protective device 20 on the back of the door 10 is located between the light emitting diode 40 and the sensor 30, so that the light emitting diode 40 Prevents light from being applied to the sensor 30.
도어(10)배면에 형성되는 보호구(20)는 형태에 관계없이 도어(10)개방시 센서(30)에 인가되는 빛을 차단시키고 도어(10)닫힘시는 빛을 차단시키지 않으면 된다. 마이콤(50)은 센서(30)의 검출출력을 인식하여 도어(10)가 닫혔을 때는 추출키 입력시 정상적인 추출동작이 이루어지게 하고, 도어(10)가 열렸을 때는 추출키가 입력되더라도 추출동작을 수행시키지 않으며, 도어(10)개방되었을 때 추출키가 눌렸을 경우 테이프 추출을 시키지 않음은 물론 화면이나 FLT 등의 표시소자에 도어개방중임을 표시하는 문자를 디스플레이시킨다.The protective device 20 formed on the rear surface of the door 10 may block light applied to the sensor 30 at the time of opening the door 10, and may not block light when the door 10 is closed. The microcomputer 50 recognizes the detection output of the sensor 30 so that a normal extraction operation is performed when the extraction key is input when the door 10 is closed, and the extraction operation is performed even when the extraction key is input when the door 10 is opened. If the extraction key is pressed when the door 10 is opened, the tape extraction is not performed, and a character indicating that the door is being opened is displayed on a display device such as a screen or an FLT.
이러한 구성의 본 발명에서 도어(10)가 개방되지 않았을 경우 발광다이오드(40)의 빛이 센서(30)에 그대로 인가되고 도어(10)가 개방되면 보호구(20)가 발광다이오드(40)의 빛을 차단하여 센서(30)에 인가되는 빛이 없게 된다.When the door 10 is not opened in the present invention having such a configuration, the light of the light emitting diode 40 is applied to the sensor 30 as it is, and when the door 10 is opened, the protective device 20 is light of the light emitting diode 40. By blocking the light is not applied to the sensor 30.
센서(30)는 발광다이오드(40)의 빛을 감지하느냐 못하느냐에 따라 각기 다른 센서출력을 출력시키게되므로 마이콤(50)에서는 상기 센서(30)출력을 감지하여 도어(10)가 개방되었는지 여부를 인식하게 된다. 마이콤(50)은 테이프 추출키가 눌렸을 경우 상기된 센서(30)출력을 감지하여 도어(10)가 개방되었는지 또는 닫혔있는지를 판단할 수 있게 되고, 테이프 추출키가 눌렸을 때 도어(10)가 닫혀 있는 것으로 판단되면 로딩모터를 회전시켜 정상적인 테이프 추출동작이 이루어지게 한다.Since the sensor 30 outputs different sensor outputs depending on whether the light of the light emitting diode 40 is detected or not, the microcomputer 50 detects the sensor 30 output to recognize whether the door 10 is opened. Done. When the tape extraction key is pressed, the microcomputer 50 may detect whether the door 10 is opened or closed by detecting the output of the sensor 30 described above, and the door 10 when the tape extraction key is pressed. If it is determined that the closing is to rotate the loading motor to perform a normal tape extraction operation.
즉 도어(10)가 닫혀 있는 경우는 도어(10)를 밀어 손가락또는 다른 이물질이 투입되지 않은 상태이므로 테이프 추출키 입력시 정상적인 테이프 추출동작을 수행시키게 되는 것이다.That is, when the door 10 is closed, the finger 10 or other foreign substances are not pushed by pushing the door 10 so that the normal tape extraction operation is performed when the tape extraction key is input.
그러나 테이프 추출키가 눌렸을 때 센서(30)출력을 감지한 결과가 도어(10)가 개방된 것으로 판단되면 로딩모터 구동을 중단시켜 테이프 추출동작을 수행시키지 않는다.However, when it is determined that the door 10 is opened when the output of the sensor 30 is detected when the tape extraction key is pressed, the driving of the loading motor is stopped and the tape extraction operation is not performed.
즉 도어(10)가 개방된 것으로 판단되면 테이프 추출키가 눌리더라도 테이프 추출동작을 수행시키지 않으므로 손가락부상 등의 사고를 미연에 방지시키는 것이다.That is, if it is determined that the door 10 is opened, the tape extraction operation is not performed even if the tape extraction key is pressed, thereby preventing an accident such as a finger injury.
또한 도어(10)가 개방된 상태에서 테이프 추출키가 눌리면 테이프 추출동작을 수행시키지 않는 한편 화면 또는 FLT에 도어(10)개방을 나타내는 경고문자를 디스플레이시키도록 하므로써 테이프 추출이 되지 않는 이유가 도어(10)개방에 의해 테이프 추출동작이 수행되지 않고 있음을 알리게 된다.In addition, if the tape ejection key is pressed while the door 10 is opened, the tape ejection operation is not performed while the warning character indicating the opening of the door 10 is displayed on the screen or the FLT. 10) By opening, the tape extraction operation is not performed.
이상에서 살펴 본 바와 같이 본 발명은 VCR의 도어가 개방된 상태에서 테이프 추출키가 눌리면 테이프 추출동작을 수행시키지 않고 경고문자를 디스플레이시킴으로써 도어가 개방된 상태에서 테이프 추출동작이 일어나 도어가 파손되거나 손가락을 부상당하는 문제점을 해결하는 것이다.As described above, according to the present invention, if the tape extraction key is pressed while the door of the VCR is opened, the tape extraction operation occurs while the door is opened by displaying a warning letter without performing the tape extraction operation. It is to solve the problem of getting injured.
