・−′ １（ｊ　　　　　　／／ ■〕：＋ＨThe figure shows an embodiment in which the present invention is applied to a disk cassette attaching/detaching device for an electronic camera.
Figure B is a top and bottom view of the disc cassette with the shutter open, Figure 2 is a top view of the disc cassette attachment/detachment device, and Figure 3 shows the disc cassette in the state just before it is inserted into the cassette holder. Figure 4 shows the state immediately after the above-mentioned insertion.
Figure 5 is a cross-sectional view taken along the IV-IV edge line arrow, and Figure 5 is a cross-sectional view taken along the ■-V line in Figure 2 when the disk cassette has been installed.
゛Cross-sectional view, Figure 6 is a view similar to Figure 4 showing the state immediately after the cassette holder has been lowered and crimped onto the mechanical board, and Figure 7 shows the state where the center core of the disk is being pressed. A view similar to FIG. 4, FIG. 8 is a view similar to FIG. 4 showing a state in which the pressing member is separated from the center core after the above compression is completed, and the disk cassette installation is completed, and FIG. 9 is a view when the above installation is completed. FIG. 10, which is similar to FIG. 3, is a diagram showing the relationship between the rotation angle of the cam wheel (horizontal axis) and the descending distance of the leaf spring at the tip of the second lever (vertical axis).

Claims

[Scope of utility model registration request]

a first lever rotatable about a fulcrum shaft; a cassette holder pivotally supported by the first lever; a second lever rotatable about the fulcrum shaft; 2
a first spring tensioned between the lever and the first lever; a second spring biasing the second lever in a backward motion; and a second spring provided at one end of the second lever. a cam follower that engages with the cam; and a pressing member that is provided at the other end of the second lever and that elastically presses the center core of the disk in the disk cassette; By rotating the lever in the forward direction against the second spring, the first lever is rotated in the forward direction via the first spring, thereby lowering the cassette holder, and this lowering lowers the cassette holder. After the holder is crimped to the reference height, the second lever is continued to be rotated forward against the first spring to push the center core of the disk onto the rotational drive shaft with the pressing member, and A disk cassette attaching/detaching device characterized in that the second lever is returned by a predetermined distance by subsequent rotation of a cam, thereby separating the suppressing member from the center core.
