Description
제1도는 본 발명에 의한 비디오 카세트 플레이어의 구성도.1 is a block diagram of a video cassette player according to the present invention.
제2도는 본 발명에 의한 테이프 잔량표시를 위한 디지트론의 표시상태도.2 is a display state of a digitron for the remaining tape display according to the present invention.
본 발명은 비디오 카세트 플레이어에 관한 것으로서, 특히 디지트론상에 테이프 잔량을 표시할 수 있는 비디오 카세트 플레이어 및 테이프 잔량 표시방법에 관한 것이다.The present invention relates to a video cassette player, and more particularly, to a video cassette player and a tape remaining amount display method capable of displaying the remaining amount of tape on a digitron.
비디오 카세트 플레이어의 사용시에 현재의 비디오 테이프의 잔량을 파악할 수 있는 것이 편집이나 녹화나 재생동작중에 매우 필요하다. 오디오 카세트 플레이어는 투명창을 통하여 테이프의 잔량여부를 눈으로 확인할 수 있으나, 비디오 카세트 플레이어는 데크 구조상 테이프의 잔량을 기계적인 구조로 파악할 수 있도록 구성한다는 것이 매우 곤란하다.When using a video cassette player, it is very necessary during editing, recording or playback operation to be able to grasp the remaining amount of video tape. The audio cassette player can visually check the remaining capacity of the tape through the transparent window, but it is very difficult to configure the video cassette player so that the remaining capacity of the tape can be understood as a mechanical structure due to the deck structure.
따라서, 최근에는 일부 제품에서 테이프잔량을 계산하여 텔레비젼세트의 스크린상에 온스크린방식으로 표시하는 기술을 개시하고 있다. 이러한 온스크린방식을 채용하지 않은 제품에서는 테이프를 꺼내서 보지않은 이상 테이프 잔량을 파악할 수 없었다. 테이프 잔량표시의 온스크린 방식은 온 스크린표시의 제한으로 테이프 잔량을 세밀하게 구분하여 표시하지 못하므로 정확한 잔량표시가 어려웠다.Therefore, in recent years, some products have disclosed a technique for calculating the remaining amount of tape and displaying it on-screen on a television set screen. In products that did not adopt this on-screen method, the amount of tape remaining could not be determined without removing the tape. The on-screen method of the remaining tape display is difficult to accurately display the remaining amount of tape because the remaining amount of tape cannot be displayed in detail due to the limitation of the on-screen display.
본 발명의 목적은 이와같은 종래 기술의 문제점을 해결하기 위하여 세트의 디지트론상에 테이프 잔량표시를 세밀하게 할 수 있는 비디오 카세트 플레이어 및 테이프 잔량표시방법을 제공하는 데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a video cassette player and a tape remaining amount display method capable of finely displaying a remaining tape amount on a set of digitrons in order to solve such problems of the prior art.

Correspondingly, the system control unit for controlling the display of the remaining cape by turning on and off the segments on the digitron.
또한, 본 발명의 테이프 잔량 표시방법은 데크내에 테이프의 삽입이 감지되면 상기 디지트론 상의 테이프 잔량표시모드용 세그먼트를 점등시키는 단계; 재생/녹화모드에 따라서 녹화모드시에는 디지트론상의 세그먼트열을 모두 점등시키는 단계; 테이프 이송동작에 의해 상기 릴센서 및 캡스턴서보제어부를 통해 테이프 감김정보 및 캡스턴 주파수신호를 시스템제어부에서 입력하여 테이프 잔량을 산출하는 단계; 및 산출된 테이프 잔량정보에 따라서 디지트론상의 세그먼트열을 테이프 회전방향에 따라서 재생모드이면 순차적으로 점등시키고, 녹화모드이면 순차적으로 소등시키는 단계를 구비하는 것을 특징으로 한다.In addition, the remaining tape display method of the present invention comprises the steps of: lighting a segment for the remaining tape display mode on the digitron when the tape is inserted into the deck; Lighting all segment strings on the digitron in the recording mode according to the playback / recording mode; Calculating the remaining tape amount by inputting the tape winding information and the capstan frequency signal through a reel sensor and the capstan servo control unit by a tape transfer operation from a system controller; And sequentially turning on the segment string on the digitron according to the calculated tape remaining amount information in the playback mode in the playback mode, and sequentially turning off in the recording mode.
이하, 첨부한 도면을 참조하여 본 발며을 보다 상세하게 설명하고자 한다. 제 1 도는 본 발명에 의한 비디오 카세트 플레이어의 구성을 나타낸다. 비디오 카세트 플레이어는 릴센서(10), 캡스턴서보제어부(20), 명령입력부(30), 디지트론(40), 시스템제어부(50)을 포함한다. 릴센서(10)는 세트의 데크부의 테이크업릴 및 공급릴에 밀결합되어 테이프 감김상태 정보를 발생한다. 캡스턴 서보제어부(20)는 캡스턴모터를 소정의 속도로 서보제어하여 테이프를 이송시키고 캡스턴모터에 밀결합된 주파수발생기를 통해서 캡스턴 주파수 신호를 얻어서 발생한다. 명령입력부(30)는 세트의 전면패널부의 키나 스위치입력 또는 수광부를 통한 리모콘신호의 입력에 따라 명령신호를 발생한다. 디지트론(40)은 제 2 도에 도시한 바와같이 테이프 잔량표시모드용 세그먼트(60)와 12개의 세그먼트(A-L)들로 이루어진 잔량표시열로 구성된다. 테이프 잔량표시모드용 세그먼트(60)는 테이프삽입에 의해 점등된다. 잔량표시열은 다음 [표 1]에 나타낸 바와같이 산출된 테이프 잔량에 따라 순차적으로 점소등된다.Hereinafter, with reference to the accompanying drawings will be described in detail the present invention. 1 shows the configuration of a video cassette player according to the present invention. The video cassette player includes a reel sensor 10, a capstan servo control unit 20, a command input unit 30, a digitron 40, and a system controller 50. The reel sensor 10 is tightly coupled to the take-up reel and the supply reel of the deck portion of the set to generate the tape wound state information. The capstan servo controller 20 generates the capstan frequency signal through a frequency generator tightly coupled to the capstan motor by servo-controlling the capstan motor at a predetermined speed. The command input unit 30 generates a command signal according to a key of the front panel of the set or a switch input or a remote control signal input through the light receiving unit. As shown in FIG. 2, the digitron 40 is composed of a segment 60 for the remaining tape display mode and a remaining display column composed of twelve segments A-L. The tape remaining amount display mode segment 60 is turned on by tape insertion. The remaining amount display string is sequentially turned on in accordance with the calculated remaining tape amount as shown in the following [Table 1].
[표 1]TABLE 1
상기 [표 1]은 예를들어 서러명한 것이지 본 발명이 이것으로 한정된다는 것은 아니다. T-90이나 T-160도 가능하다. 또한, 표시열의 세그먼트의 수도 12개로 한정되는 것이 아니라 이와같은 방식으로 더 많이 혹은 더 적게 할당할 수도 있다.[Table 1] is for example several names, but the present invention is not limited thereto. The T-90 or T-160 is also available. In addition, the number of segments of the display column is not limited to 12, but more or less can be allocated in this manner.
시스템제어부(50)에서는 데크내에 테이프의 삽입이 감지되면 상기 디지트론 상의 테이프 잔량표시모드용 세그먼트(60)를 점등시키고, 명령입력부(30)의 재생/녹화모드에 따라서 녹화모드시에에는 디지트론상(40)의 세그먼트열(A-L)을 모두 점등시키며, 캡스턴 서보제어부(20)의 테이프 이송동작에 의해 상기 릴센서(10) 및 캡스턴서보제어부(20)를 통해 테이프 감김정보 및 캡스턴 주파수신호를 입력하여 테이프 잔량을 산출하고, 산출된 테이프 잔량정보에 따라서 디지트론(50) 상의 세그먼트열(A-L)을 테이프 회전방향에 따라서, 재생모드이면 순차적으로 점등시키고, 녹화모드이면 순차적으로 소등시킨다. 즉, 시스템제어부(50)에서는 정회전방향이면 A세그먼트로부터 차례로 점소등시켜서 L세그먼트로 가고 역회전방향이면 정방향에 대해 역순으로 점소등시킨다.The system controller 50 turns on the tape remaining amount display mode segment 60 on the digitron when the tape is inserted into the deck, and the digitron in the recording mode according to the playback / recording mode of the command input unit 30. The segment string AL of the image 40 is turned on, and the tape winding information and the capstan frequency signal are transmitted through the reel sensor 10 and the capstan servo controller 20 by the tape feed operation of the capstan servo controller 20. The remaining tape amount is calculated by inputting, and the segment string AL on the digitron 50 is sequentially lighted in the playback mode according to the calculated tape remaining information, and turned off sequentially in the recording mode. That is, in the forward rotation direction, the system control unit 50 turns on the A segment in order, and goes to the L segment. In the reverse rotation direction, the system control section 50 turns on the reverse direction in the forward direction.
이상과 같이 본 발명에서는 테이프잔량을 디지트론상에 복수의 세그먼트들로 세분하여 표시할 수 있으므로 보다 정확하게 테이프 잔량을 파악할 수 있도록 표시할 수 있다. 본 발명의 실시예에서는 12개의 세그먼트로 세분하여 테이프 잔량을 표시하였으나 세그먼트의 밝기단계를 다단계로 하므로써 보다 정밀한 잔량을 표시할 수도 있다.As described above, in the present invention, since the remaining tape can be divided into a plurality of segments on the digitron, the remaining tape can be displayed more accurately. In the exemplary embodiment of the present invention, the remaining tape amount is displayed by dividing into 12 segments, but the more precise remaining amount may be displayed by making the brightness level of the segment into multiple stages.
