Abstract

본 발명은 VCR 시청중 갑작스런 정전시, 수납되어 있는 카세트 테이프가 자동으로 이젝트되는 카세트 테이프의 자동 이젝트장치에 관한 것으로, 이를 해결하기 위하여, VCR 시청중 정전 여부를 검출하는 정전검출 제어수단, 정전검출 제어수단에 의하여 정전 상태로 판정되면, VCR 시스템내에 수납되어 있는 카세트 테이프가 이젝트될 수 있도록 구동력을 제공하는 이젝트 구동수단으로 이루어짐으로써, 카세트 테이프가 VCR 시스템에 수납된 상태에서 정전이 발생되더라도 자동으로 수납되어 있던 카세트 테이프를 이젝트시킬 수 있는 효과가 있다.The present invention relates to an automatic ejection apparatus of a cassette tape in which a cassette tape is automatically ejected during sudden power failure while watching a VCR. To solve this problem, an electrostatic detection control means for detecting a power failure while watching a VCR, an electrostatic detection When it is determined by the control means that the power failure state, the ejection drive means is provided to provide a driving force for ejecting the cassette tape stored in the VCR system, so that even if a power failure occurs in the state where the cassette tape is stored in the VCR system, There is an effect that the cassette tape that has been stored can be ejected.

Claims

A VCR apparatus for reproducing and recording a cassette tape housed in a VCR system, comprising: an electrostatic detection control means for detecting whether a power failure occurs while watching a VCR; And an ejection driving means for providing a driving force for ejecting the cassette tape stored in the VCR system when it is determined by the electrostatic detection control means.

The power supply unit of claim 1, wherein the power failure detection control unit comprises: a power supply unit 10 for converting the power applied from the outside into the required power to the VCR system; The power failure state 12 and the power supply unit 10 and the power supply / discharge unit 12 respectively determine the power failure state based on the power supply, and in response to the determination, the cassette tape stored in the VCR system is automatically To the first and second clock drivers 16 and 18 for supplying the oscillation clock required for the system in response to the control signal of the microcomputer 14 and the microcomputer 14 for applying a predetermined control signal to be ejected. Automatic ejection device of the cassette tape, characterized in that made.

2. The ejector driving means according to claim 1, wherein the ejector driving means comprises: a charging motor driving charging portion 20 for discharging power charged for ejecting an cassette tape housed in the VCR system, and a cassette housed in the VCR system; The power is discharged from the loading motor driving charging unit 20 based on a loading motor 26 providing a driving force to allow the tape to be ejected, and an on / off control signal corresponding to the result of the power failure determination. The first path control unit 22 performs a switching operation to be supplied to the control unit 26 and a control signal for supplying power to the loading motor 26 starting from the determination of power failure, and after the predetermined time, the loading motor ( And a timer circuit (24) for applying a control signal for terminating the power supply.
