Appeal No. 1998-0205
Application No. 08/464,150
BACKGROUND
The invention is directed to a cassette holder moving mechanism for a magnetic video cassette
player/recorder. Claim 5 is reproduced below.1
5. A magnetic recording and reproduction apparatus having a main unit with a base chassis, and a
cassette holder defining front, rear, and opposite sides and adapted to hold a box-type cassette case
having a wound magnetic tape, comprising:
a slide chassis slidably provided in said main unit for holding said cassette holder such that said
cassette holder is capable of being vertically moved between an up position and a down position,
wherein said cassette holder remains substantially level while ascending and descending between said
up and down positions;
a first moving mechanism and a second moving mechanism which are operatively connected
between said cassette holder and said slide chassis and are disposed at respective opposite sides of
said cassette holder, wherein said first moving mechanism and said second moving mechanism guide
said cassette holder between said up and down positions while maintaining said cassette holder
substantially level;
connecting means for synchronously connecting said first and second moving mechanisms, and
ensuring that said cassette holder remains substantially level and substantially parallel to said slide
chassis, comprising:
a rack and a pinion engaging with said rack and provided at one end of each moving
mechanism; and
a connecting rod rotatably supported on said cassette holder and having said pinions mounted to both
ends of said connecting rod.
1We note that the preliminary amendment filed June 5, 1995 (Paper No. 3) directed cancellation of
Claims 1-4, but the amendment has not been formally entered. Also, appellant’s amendment filed December
22, 1995 (Paper No. 6) incorrectly directed amendment and re-entry of Claim “1.” Consistent with
appellant’s appendix of claims with the Brief, we take amended Claim “1” in the file wrapper to be Claim 5.
