Total Claims: 4
Claim 1
Independent Claim 217 words
A tape cassette loading device for a cassette type video tape recorder comprising: a housing, brackets formed on both sides of said housing, said brackets having guiding grooves disposed on both interior sides of said brackets, a movable cassette holder adapted to contain a video tape cassette, said movable cassette holder having pins attached thereto which are slidably engaged in said guiding grooves, actuating levers operatively associated with said brackets, said actuating levers having a recess disposed at one end thereof for slidably receiving said pin, and gear means disposed at the other end thereof, and driving members pivotally mounted on said brackets for engagement with said gear means, said driving members having arms which form a substantially V-shaped configuration, one of said arms defining an arcuate shaped gearing surface for receiving said gear means and the other of said arms extending to form a door member, whereby, upon the closing of the door member, said door member engages the video tape cassette disposed in the movable cassette holder and the gear means rotates to move along the gearing surface of said driving member and said pin moves in said guiding grooves by the action of said actuating levers whereby said actuating levers transfer the cassette holder from a cassette take-up position to a cassette operation position.
