ABSTRACT:
A cassette loading and unloading device for use in a video cassette recorder ("VCR") comprises a door hinged at the front panel such that it is inwardly swingable, a first and a second side walls, each of which has an upper and a lower guide slots, a cassette holder having at each side surface an upper and a lower slide pins which are respectively fitted in and movable along the upper and the lower guide slots of the side walls, and a first and a second pivot arms tightly fitted on both ends of a shaft rotatably held by the side walls. The first pivot arm has a gear portion at a bottom end. A door opener is rotatably mounted onto the first side wall adjacent to the first pivot arm. The door opener is linked at an upper portion to the door and at a lower portion provided with a cam follower. A lengthwise movable elongate bar has a rack portion engaged with the gear portion of the first pivot arm and a cam provided with a cam surface. Upon an unloading mode of the VCR, the cam follower of the door opener comes into contact with and follows the cam surface so that the door is opened before the pivot arms are rotated.
