摘要

An automatic door opening mechanism for ejecting a video cassette tape of a video cassette recorder (VCR) includes a door mounted at both sides on door brackets in front of a cassette deck opening for inserting/ejecting a cassette tape so as to be opened upwardly and an actuator lever fixed on one end of an actuator shaft rotatably mounted on main frame. The actuator lever has a door locking part formed on one end and a button pressing part formed on the other end. A further door locking part is fixed on the other end of the actuator shaft. A retention arm is fixed on the actuator shaft in the middle thereof. The retention arm has a stopper tiltably mounted on its top. The stopper is vertically positioned under the cassette deck opening so as to be engaged with front and rear lower edges of the cassette tape and to be tilted inwardly by being engaged with the rear lower edge of the cassette tape when inserting the same through the opening. The stopper is returned to its vertical position after complete insertion of the cassette tape.
