  The technique of Patent Document 1 described above is an optical disc case that is inserted into and removed from an information recording / reproducing apparatus in a state in which the optical disc is stored, and includes a first case member that covers one side of the optical disc and a second case that covers the opposite side of the optical disc. A movable connecting portion that movably connects one end of each of the first and second case members so as to be able to open and close an optical disk storage area formed by the first and second case members; The configuration has a spindle hole formed in each of the second case members and a head insertion hole formed in each of the first and second case members. That is, the first case member and the second case member are connected by the movable connecting portion, so that the optical disc storage area can be opened and closed.

  However, in such an optical disc case, it is necessary to separately manufacture the components of the movable connecting portion, which causes a great problem in terms of the number of components and the ease of assembly.

  Therefore, the present invention has been made to solve the above problems, and a highly reliable disk case that has a small number of parts and can be manufactured easily and at low cost without requiring a complicated assembly process. The purpose is to provide.

  In order to solve the above-described problems, the present invention provides a first case member that covers one side of the disc and a surface opposite to the disc in a disc case that is inserted into and removed from the information recording / reproducing apparatus with the disc stored. The disc surface is connected to one end of the first and second case members so as to be openable and closable so as to open and close a disc storage area formed by the second case member and the first and second case members. And a movable connecting portion that is rotated inward.

  According to the present invention, in the optical disk case, the movable connecting portion that movably connects the respective ends of the bottom case member and the top case member so that the optical disk storage region formed by the bottom case member and the top case member can be opened and closed. By providing, a component can be comprised by two points, a bottom case member and a top case member, and component manufacture and an assembly can be performed easily.

  In addition, since rotation is free only in the direction of the disc surface around the movable connecting part, the chance of dirt such as fingerprints adhering to the information recording surface of the disc is reduced as much as possible, and the disc can be easily removed from the optical disc case. Can do.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIGS. 1 to 2 (a) and 2 (b) are perspective views showing the configuration of a disk case according to an embodiment of the present invention. FIG. 1 is a perspective view showing a state in which an optical disc is stored and an optical disc case is closed. FIG. 2A is a perspective view showing a state where the optical disk is housed and the optical disk case is opened. FIG. 2B is a perspective view showing a state in which the optical disk is not stored and the optical disk case is opened.

  As shown in FIGS. 1 and 2A and 2B, the optical disk case 100 includes a top case member 3 (first case member) and a bottom case member 5 (second case member). Insertion holes 9a and 9b are formed. The head insertion holes 9 a and 9 b are opened on one side of the optical disk case 100.

  The top case member 3 and the bottom case member 5 are connected by a movable connecting portion 11. The movable connecting portion 11 is formed on the periphery of the top case member 3 and the bottom case member 5 and is provided in the vicinity of the head insertion holes 9a and 9b. The movable connecting portion 11 is rotated counterclockwise (in the direction of the arrow in the figure) with the rotation fixing pin provided on the bottom case member 5 being inserted into the rotation fixing hole of the top case member 3. Rotate. As a result, the top case member 3 is opened by rotating in the in-plane direction of the disc, and the disc 7 can be taken in and out.

  FIG. 3 is a view showing the structure of the bottom case member, and FIG. 4 is an enlarged view of the rotation fixing pin. FIG. 5 is a view showing the structure of the top case member. As shown in FIG. 3, the bottom case member 5 includes a rotation fixing pin 13, a locking pin 17, a rib 19, and a reinforcing rib 20.

  The rotation fixing pin 13 is provided in the vicinity of the head insertion hole 9b on the periphery thereof, and is inserted into the rotation fixing hole 15 provided in the top case member 3 shown in FIG. 5 as described above. Thereby, the bottom case member 5 and the top case member 3 are fixed and rotated counterclockwise. Since the rotation fixing pin 13 has a cylindrical projection shape as shown in the enlarged view of FIG. 5, the operator can easily attach it by simply inserting it into the rotation fixing hole 15 during assembly. It cannot be easily removed.

The locking pin 17 is provided with a locking pin 17 at one end of the peripheral portion of the bottom case member 5 and is mechanically connected to a locking leaf spring 21 of the top case member 3 described later. The locking pin 17 and the rotation fixing pin 13 are arranged at positions facing each other on the bottom case member 5, that is, at positions farthest from each other. This is because a large force is applied when the disk is stored and the case is closed, and the case is easily closed.

  The rib 19 is formed at a part of the peripheral edge of the bottom case member 5 in order to fix the disk, and is formed at a position facing the opening portion of the head insertion hole 9b. The rib 19 is provided in a portion that does not come into contact with the locking leaf spring 21 when the case is locked.

  The reinforcing rib 20 is provided in the vicinity of the rotation fixing pin 13 and is formed on a part of the peripheral edge of the bottom case member 5. The reinforcing rib 20 serves as a stopper so that when the case is opened, it is brought into contact with the rib 23 provided on the top case member 3 so as not to be opened further.

  As shown in FIG. 5, the top case member 3 includes a rotation fixing hole 15, a locking plate spring 21, and a rib 23.

  The rotation fixing hole 15 is provided at a position where it is aligned with the rotation fixing pin 13, and the rotation fixing pin 13 is inserted to rotate and fix the bottom case member 5 and the top case member 3. The state in which the rotation fixing pin 13 is inserted into the rotation fixing hole 15 is referred to as a movable connecting portion 11.

  As will be described in detail later, the locking leaf spring 21 is provided integrally with the peripheral portion of the top case member 3, and is configured such that the recessed portion is hooked on the locking pin 17 of the bottom case member 5.

  The ribs 23 are provided at the peripheral edge of the top case member 3 and cover portions of the bottom case member 5 that are not covered with the ribs 19 and the reinforcing ribs 20. That is, when the case itself is closed, the rib 19 of the bottom case member 5, the reinforcing rib 20, and the rib 23 of the top case member 3 just cover the periphery of the disk. Further, the rotation fixing hole 15 is provided on the rib 23. This is because the rotation fixing pin 13 is not on the rib 19 and therefore it is necessary to provide it on the rib 23 to cover that portion when the case is closed.

  FIG. 6 is an enlarged view showing the structure of the locking mechanism of the optical disk case.

  As shown in FIG. 6, a locking leaf spring 21 is integrally provided on the peripheral edge of the top case member 3, and an inner portion (portion on the inner circumferential side) of the locking leaf spring 21 is formed in a hollow shape. ing. When the locking pin 17 is caught in the hollow shape, the top case member 3 is prevented from opening without permission.

  When opening the optical disk case 100 and taking out the disk, the user holds the bottom case member 5 and rotates the top case member 3 counterclockwise in the direction of the disk surface. When the case is closed, the lock pin 17 is caught in the recess of the lock plate spring 21 so that the case is locked. By rotating the top case member 3 slightly in the direction of arrow A, the lock plate The tip of the spring 21 moves in the direction of arrow B and the lock is released. When the lock is released, rotate the case counterclockwise in the disc surface and open the case. As the case is opened, part of the ribs 23 of the top case member 3 comes into contact with the reinforcing ribs 20 of the bottom case member 5 so that the case cannot be opened any further.

When the disc is put in the optical disc case 100 and the case is closed, the user holds the top case member 3 and rotates the bottom case member 5 in the disc surface in the clockwise direction. The tip of the locking plate spring 21 and the locking pin 17 collide, but by applying a little force, the tip of the locking plate spring 21 moves in the direction of arrow B, and the locking pin 17 fits in the recess of the locking plate spring 21. . As a result, the case is locked.

  As described above, by providing a movable coupling portion that movably couples one end of each of the bottom case member and the top case member, rotation around the movable coupling portion is free only in the disk surface direction, and the disc can be easily Furthermore, since the optical disk case requires only two components (bottom case member and top case member) and one movable connecting portion, the number of components can be reduced and the assembly can be facilitated.

  In addition, the bottom case member and the top case member are exclusively provided with ribs for restraining the horizontal movement of the disc, so that the bottom case member and the top case are rotated while the top case member is rotated in the disc surface direction. The ribs of the case member do not contact each other. However, in order to control the rotation of the top case member, the reinforcing ribs of the bottom case member and the ribs of the top case member come into contact when the case is opened.

  In addition, since the case is locked by the locking leaf spring integrated with the rib of the top case member and the locking pin integrated with the bottom case member, the optical disk can be manufactured without separately manufacturing the locking parts. The case can have a lock mechanism.

  Further, since the lock mechanism is disposed at the farthest position from the movable connecting portion in the optical disk case, a large force is applied when the disk is stored and the case is closed, and the case is easily closed.

  In addition, this invention is not limited to the said embodiment, In the implementation stage, it can change variously in the range which does not deviate from the summary.
