A disc device includes: a casing including: a casing body that has a housing section of a disc 4 and houses a device body including a drive unit for rotating the disc 4 ; and a cover section rotatably supported on the casing body for closing the housing section. The casing includes: a rotation stop mechanism 5 for stopping rotation of the disc 4 when the cover section is opened. The rotation stop mechanism 5 includes a lever 6 rotatably supported on the casing body and having a contact section 631 contacting with the disc 4 when the cover section is opened; a biasing unit 7 provided on the lever 6 for biasing the contact section 631 toward an edge face of the disc 4 ; and a first releasing unit 13 B provided in a protruding state on the cover section, the releasing unit 13 B contacting with the lever 6 to rotate the lever 6 for releasing contact between the contact section 631 and the disc 4 when the cover section is closed. The contact section 631 has a contact face 632 inclined against the rotational tangent direction of the disc 4.
1. A disc device, comprising a casing including: a casing body that has a housing section for housing a disc therein and houses a device body including a drive unit for rotating the disc; and a cover section rotatably supported on the casing body for closing an opening for housing the disc in the housing section,
wherein a rotation stop mechanism is provided in the casing for stopping rotation of the disc when the cover section is opened,
the rotation stop mechanism includes: a lever rotatably supported on the casing body and having a contact section contacting with an edge face of the disc set therein when the cover section is opened; a biasing unit provided on the lever for biasing the contact section in a direction toward the edge face of the disc; and a first releasing unit provided in a protruding state on the cover section, the first releasing unit contacting with the lever to rotate the lever in a direction away from the edge face of the disc when the cover section is closed for releasing contact between the contact section and the edge face of the disc, and
the contact section has a contact face extending in a direction inclined against a rotational tangent direction of the disc.
2. The disc device according to claim 1 , wherein the lever rotates in the same direction as that of the disc, and the contact section contacts with the edge face of the disc.
3. The disc device according to claim 1 , wherein the biasing unit is a spring member attached to the casing body.
4. The disc device according to claim 1 , wherein the biasing unit is a magnetic member attracting or repelling the lever with magnetism.
5. The disc device according to claim 1 , wherein the lever has an inclined face with which the first releasing unit contacts, the inclined face inclined against a direction in which the first releasing unit advances and retracts.
6. The disc device according to claim 1 , wherein the cover section is provided with a second releasing unit that contacts with the lever to rotate the lever in the direction away from the edge face of the disc when the cover section is substantially fully opened.
