Holder structure in a cassette player

Claim 2

A cassette holder structure in an information recording and/or reproducing apparatus operable with the use of a cassette containing an information carrier medium, which structure comprises: a support structure; a cassette holder supported by said support structure for movement between a first position, at which the cassette holder is ready to receive a cassette housing an information carrier medium, and a second position at which information can be recorded on or reproduced from said information carrier medium contained in said cassette; a detent member defined in and juxtapositioned to a front edge of said cassette; a generally elongated elastic releaseable catch member carried by said cassette holder and resiliently engageable with said detent member defined in said cassette; and a finger assembly secured to said support structure to be engaged with said elastic releaseable catch member to disengage said catch member from said detent member in the cassette when said cassette holder is moved to said first cassette receiving position, but to be disengaged from said elastic releaseable catch member so that said catch member will engage said detent member in the cassette when said cassette holder with the cassette inserted therein is moved a predetermined distance from said cassette receiving first position towards said second information recording and/or reproducing position.

Claim 3

The holder structure of claim 1, wherein said elastic releaseable catch member comprises a generally elongated leaf spring member having one end rigidly secured to said cassette holder, and a catch block rigidly mounted on the other end of said leaf spring member and engageable with said detent recess in said cassette.

Claim 4

The holder structure of claim 2, wherein said detent member is a detent recess defined in said cassette.

Claim 5

The holder structure as claimed in claim 1, wherein the information carrier medium is a medium selected from the group consisting of a magnetic tape, a magnetic disk and an optical disk.

Claim 6

A cassette holder structure in an information recording and/or reproducing apparatus operable with the use of a cassette containing an information carrier medium, which structure comprises: a support structure; a cassette holder supported by said support structure for movement between a first position, at which the cassette holder is ready to receive a cassette housing an information carrier medium, and a second position at which information can be recorded on or reproduced from said information carrier medium contained in said cassette; a detent member defined in and juxtapositioned to a front edge of said cassette; a generally elongated elastic releaseable catch member carried by said cassette holder and resiliently engageable with said detent member defined in said cassette; a finger assembly mounted on said cassette holder for movement in a direction conforming to the direction of insertion of said cassete into said cassette holder; a spring member interposed between said finger assembly and cassette holder for urging said finger assembly in a direction counter to the direction of insertion of the cassette into the cassette holder, thereby effecting said finger assembly to disengage from said elastic releaseable catch member for engagement with the detent member by the effect of its own resiliency as the cassette holder is moved a predetermined distance from said first position towards said second position; and a stopper member provided on said support structure for halting said finger assembly against said spring member when said cassette holder is moved to said first position, such that said finger assembly engages with said elastic releaseable catch member to disengage the latter from said detent member against the resiliency of said elastic releaseable catch member.

Claim 7

A cassette holder structure in an information recording and/or reproducing apparatus operable with the use of a cassette containing an information carrier medium, which structure comprises: a support structure; a cassette holder supported by said support structure for movement between a first position, at which the cassette holder is ready to receive a cassette housing an information carrier medium, and a second position at which information can be recorded on or reproduced from said information carrier medium contained in said cassette; a detent member defined in and juxtapositioned to a front edge of said cassette; a generally elongated elastic releaseable catch member carried by said cassette holder and resiliently engageable with said detent member defined in said cassette; a finger assembly mounted on said cassette holder for movement in a direction conforming to the direction of insertion of said cassete into said cassette holder; a spring member interposed between said finger assembly and cassette holder for urging said finger assembly in a direction counter to the direction of insertion of the cassette into the cassette holder, thereby effecting said finger assembly to disengage from said elastic releaseable catch member for engagement with the detent member by the effect of its own resiliency as the cassette holder is moved a predetermined distance from said first position towards said second position; and a stopper member provided on said support structure for halting said finger assembly against said spring member when said cassette holder is moved to said first position, such that said finger assembly engages with said elastic releaseable catch member to disengage the latter from said detent member against the resiliency of said elastic releaseable catch member.

Claim 8

The holder structure as claimed in claim 5, wherein the information carrier medium is a medium selected from the group consisting of a magnetic tape, a magnetic disk and an optical disk.
