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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
