Patent number: 5012364Abstract: A mechanism for loading the tape of a standard- or compact-size tape cassette against a rotary head assembly in a compatible recording/reproducing apparatus for selective use with the two types of tape cassettes. The apparatus has a main chassis with a set of fixed positioning pins for positioning the standard-size tape cassette thereon. A floating chassis, much less in size than the main chassis, is mounted thereto for displacement in a direction normal to the principal plane of the main chassis. A pair of tape loader assemblies are mounted to the main chassis for taking the tape out from the standard-size tape cassette positioned on the main chassis, or from the compact-size tape cassette positioned on the floating chassis, and for loading the tape against the rotary head assembly. A common drive cam is coupled to both the floating chassis and the tape loader assemblies via separate drive linkages in order to cause their timed travels.Type: GrantFiled: August 23, 1989Date of Patent: April 30, 1991Assignee: Victor Company of Japan, Ltd.Inventors: Hiromichi Hirayama, Masato Mihara, Mitsuo Harumatsu

Patent number: 4972278Abstract: A tape cassette driving system of a video tape recorder for driving the reels of the tape cassette comprises a main chassis for supporting a standard size tape cassette and a sub-chassis for supporting a compact size tape cassette. The main chassis carries a reel disk for driving a take up reel of the standard size tape cassette and the sub-chassis carries a drive gear adapted for engagement with the reel disk on the main chassis and further for engagement with teeth formed on the periphery of the take up reel of the compact size tape cassette. The sub-chassis is connected to the main chassis by a plurality of swing arms such that the sub-chassis is movable up and down relative to the main chassis. As a result of the connection by the swing arms, the sub-chassis is moved along a circular path when it is moved up and down and the engagement of the drive gear with the toothed part of the reel disk can be achieved smoothly.Type: GrantFiled: October 12, 1988Date of Patent: November 20, 1990Assignee: Victor Company of Japan, Ltd.Inventors: Mitsuhiko Hara, Hiromichi Hirayama, Masato Mihara, Mitsuo Harumatsu
