Description

  The present invention relates to a case capable of storing a cartridge in which a disk-shaped information medium is rotatably stored.

  In recent years, so-called disk recorders capable of recording broadcast programs on a disk-shaped medium have rapidly spread. As an information medium used in such a DVD recorder, for example, there is a disc that conforms to the DVD-R or DVD-RAM standard, but it conforms to the Blu-ray disc standard with a larger recordable capacity than the DVD. Disks (hereinafter referred to as BDs) are also becoming increasingly popular.

  Since BD uses a multi-layer disc having the same diameter of 12 cm as DVD and increases the recording density, if dust or scratches adhere to the recording surface, various data cannot be recorded or reproduced easily. Therefore, the BD is generally handled in a state of being stored in a cubic cartridge so that dust or the like does not easily adhere to the storage surface. The configuration of the BD cartridge is disclosed in Patent Document 1, for example.

  FIG. 26 is a perspective view showing an external configuration of the cartridge 100 (first cartridge). FIG. 27 is a perspective view showing the configuration of the lower half 103 and shows a state in which the upper half 102 and the disk 101 are removed.

  As shown in FIGS. 26 and 27, the cartridge 100 is constituted by a BD cartridge in which a disk 101 conforming to the BD standard is built, for example. In addition, the cartridge 100 is mainly composed of an upper half 102 (opposite plate) and a lower half 103 (plate) with a housing roughly divided.

  The lower half 103 is provided on the recording surface side of the disk 101. The upper half 102 is provided so as to engage with the lower half 103 with the disc 101 interposed therebetween in order to accommodate the disc 101 rotatably.

  The lower half 103 is formed with an opening window for exposing the recording surface of the disk 101 along the radial direction. An optical pickup and a turntable provided in a recording / reproducing apparatus for recording / reproducing the disc 101 are inserted into the opening window. A pair of shutters 107 (described later with reference to FIG. 27) are provided between the lower half 103 and the disk 101 for opening and closing the opening window.

  In the upper half 102, an exposure hole 102a is formed so that the surface (one surface) on the upper half 102 side of the disk 101 is exposed almost entirely. In order to prevent the disc 101 from falling off the exposed hole 102a, the exposed hole 102a has an opening area smaller than the size on the projection surface of the disc 101, and is not a perfect circle like the disc 101 but a substantially elliptical shape. Is formed. Further, in order to prevent the disk 101 from falling off, the lower half 103 is provided with a pair of claws 108.

  A groove 114 and a groove 115 are formed on the pair of side surfaces of the cartridge 100, respectively. A shutter opening / closing member 105 for opening and closing the shutter 107 and a shutter locking member 104 for releasing the locked state of the shutter opening / closing member 105 are disposed in the groove 114.

  The shutter lock member 104 is arranged so that it can be pressed in the direction of the arrow M, and is locked so that the shutter opening / closing member 105 does not operate in a state where the shutter is not pressed. Further, the shutter lock member 104 is urged with an elastic force so that the pressing portion 104 a disposed at one end always protrudes from the side surface of the cartridge 100. Further, the shutter opening / closing member 105 can be unlocked by pressing the shutter locking member 104. FIG. 28 shows an enlarged plan view of the periphery of the shutter lock member 104. As shown in FIG. 28, the shutter lock member 104 is disposed so as to be rotatable about the rotation shaft 106. The state shown in FIG. 28 shows a state in which the shutter opening / closing member 105 is locked, and the lock can be released by rotating the shutter opening / closing member 105 in the direction of arrow P from the state shown in the figure. Further, a pressing portion 104a exposed on the side surface of the cartridge 100 is disposed at one end of the shutter lock member 104, and the other end is opposed to the hole portion 105b of the shutter opening / closing member 105 as the shutter lock member 104 rotates. Thus, a claw portion 104b that is fitted or separated is disposed.

  The shutter opening / closing member 105 is arranged so as to be movable along the outer periphery of the disk 101 in the arrow N or in the opposite direction. A pair of shutters 107 is connected to the shutter opening / closing member 105. When the shutter 107 is moved in the direction of arrow N, the shutter 107 can be opened, and when it is moved in the direction opposite to the arrow N, the shutter 107 can be closed. . Further, the shutter opening / closing member 105 has a recess 105a formed at a portion exposed on the side surface of the cartridge 100, and a projection for opening and closing a shutter disposed on the apparatus side is fitted into the recess 105a. Or it is moved in the opposite direction. The shutter opening / closing member 105 has a hole 105b into which the claw 104b of the shutter lock member 104 can be fitted. When the claw 104b is fitted in the hole 105b, the shutter opening / closing member 105 105 is in a state where it cannot move. Further, the shutter opening / closing member 105 is formed with a tooth portion 109 at a portion between the concave portion 105a and the hole portion 105b. In addition, a pair of claw portions 108 are connected to the shutter opening / closing member 105, and the pair of claw portions 108 can be moved to the storage position or the protruding position as the shutter opening / closing member 105 moves.

  When the claw portion 108 is in the projecting position, the claw portion 108 is in a position where it overlaps on the projection surface of the disc 101, so that the disc 101 can be prevented from being detached from the cartridge 100. Further, when the claw portion is in the storage position, the claw portion 108 is retracted to a position where it does not overlap on the projection surface of the disc 101, so that the disc 101 can be removed from the cartridge 100.

  When the pressing portion 104a is pressed from the state shown in FIGS. 27 and 28, the shutter lock member 104 rotates in the arrow P direction, and the fitting state between the claw portion 104b and the hole portion 105b is released, and the shutter is released. The opening / closing member 105 is movable. By moving the shutter opening / closing member 105 in the arrow N direction from this state, the shutter 107 can be shifted from the closed state to the open state, and the pair of claw portions 108 can be moved to the storage position. As a result, the disc 101 is sandwiched between the turntable and the clamper while being in the cartridge 100, and can be rotated at a predetermined rotational speed. When recording / reproducing various data to / from the disk 101, the recording surface of the disk 101 is irradiated with laser light from the laser diode while the disk 101 is rotated at a predetermined rotational speed as described above. The recording / reproducing operation can be performed by receiving the light reflected from the surface by the optical pickup.

  On the other hand, recently, a method of using a BD standard disc as a bare disc has also been proposed. In order to cope with such usage, a mechanism that allows a user to take out a disk from a cartridge has been proposed. A cartridge equipped with such a mechanism is referred to as a second cartridge. Hereinafter, the configuration of the second cartridge will be briefly described.

  FIG. 29 is an exploded perspective view of the cartridge having the second configuration. In FIG. 29, the second cartridge 200 includes a disk 201 having a center hole 201a, an upper half 202, a lower half 203, a shutter lock member 204, a shutter opening / closing member 205, a claw portion 208, as in the first cartridge. A groove 114 and a groove 115 are provided. Since these structures are the same as those of the first cartridge, description thereof is omitted.

  The slide member 210 is disposed in the recess 202a formed in the upper half 202, and is slidable in the direction of arrow S in FIG. 30 or in the direction of arrow T in FIG. Further, pins (not shown) are formed on the back surface of the slide member 210 and are fitted into a pair of grooves 212 formed in the recess 202 a of the upper half 202. The slide member 210 has a hole 210a through which the pin 211 can be inserted.

  The pin 211 is for leaving a history of opening and closing of the slide member 210, and is restricted so that the slide member 210 cannot slide by being fitted into the hole 213 through the hole 210a. That is, unless the pin 211 is removed from the cartridge 200, the slide member 210 cannot be slid and the disk 201 cannot be removed from the cartridge 200. Once the pin 211 is removed from the cartridge 200, it cannot be mounted again. Therefore, based on the presence / absence of the pins 211, it can be determined whether the cartridge has not been removed from the cartridge or whether the cartridge has been removed.

  The groove portion 212 can slide the slide member 210 in the direction of the arrow S or T when a pin formed on the back surface of the slide member 210 is movably fitted.

  In the cartridge 200 configured as described above, the slide member 210 is disposed in the recess 202a of the upper half 202 according to the path indicated by the arrow Q as shown in FIG. At this time, the slide member 210 can be movably disposed with respect to the upper half 202 by fitting the pin formed on the back surface of the slide member 210 into the groove portion 212. Further, as indicated by an arrow R, the pin 211 is inserted through the hole 210 a of the slide member 210 and fitted into the hole 213 of the upper half 202.

  When taking out the disc 201 from the cartridge 200, first, as shown in FIG. 30, the pins 211 fitted in the holes 210a and 213 are removed as shown by the arrow U. Thus, the lock of the slide member 210 is released.

  In this state, since the movement of the shutter opening / closing member 205 coupled to the slide member 210 is locked by the shutter lock member 204, the shutter opening / closing member 205 is locked by pressing the shutter lock member 204 in the direction of the arrow M. To release. Next, the slide member 210 is slid in the arrow S direction while pressing the shutter lock member 204. Thereby, the shutter opening / closing member 205 connected to the slide member 210 is moved, and the shutter (not shown) can be shifted to the open state. The state after sliding is shown in FIG.

  When the slide member 210 is pulled out as shown in FIG. 31, the slide member 210 moves to a position where it does not overlap the disk 201 on the projection surface, and the claw portion 208 is housed in the cartridge 200. As a result, the disc 201 can be released from the restricted state and can be removed from the cartridge 200.

The outer diameter of the BD cartridge is such that the total length L, the total width W, and the thickness T are respectively
130.5mm ≦ L ≦ 131.0mm
128.5mm ≦ W ≦ 128.9mm
7.7 mm ≦ T ≦ 8.1 mm
It is. Further, the groove 114 (214) is formed so that the amount of depression from the outer surface of the side wall of the cartridge 100 (200) is 5.0 mm or less. The shutter lock member 204 has a distance D from the top of the cartridge 100 (200) in the groove 114 (214).
30.4mm ≦ D ≦ 37.7mm
In this range, it is configured to be recessed 1.3 mm from the outer surface of the side wall provided with the groove 114 (214). The above dimensions are based on the BD standard.

  However, in the cartridge shown in FIGS. 29 to 31, the slide member 210 must be slid while pressing the shutter lock member 204 when taking out the disk. Since the shutter lock member 204 is a very small component and is disposed at the bottom of the groove formed on the side surface of the cartridge 200, the pressing operation is extremely difficult, and the disk 201 is easily taken out from the cartridge 200. There was a problem that I could not.

FIG. 3 is a plan view of the state shown in FIG. FIG. 4 is a plan view showing a state in which the cartridge is stored in the case, and is a state in which the cartridge is stored in a direction different from the storage direction shown in FIGS. 2 and 3. FIG. 5 shows a state in which the slide member is pulled out. FIG. 6 is a plan view of the back surface side in the state shown in FIG. 5, but the cartridge in the state shown in the figure is originally hidden by the bottom plate, but is drawn with a solid line in consideration of the visibility of the drawing. . FIG. 7 is a perspective view showing a state in which the disc is removed from the cartridge. Also, in the plan views of FIGS. 3 to 6, the vicinity of the groove portions 214 and 215 of the cartridge 200 is partially cut away in order to clearly express the action of the protrusion on the cartridge.

  In FIG. 1, the case 1 is made of, for example, resin. The case 1 includes a bottom plate 1a that is configured in a flat plate shape, a first side plate 1b that is erected perpendicular to the bottom plate 1a, and a first side plate 1b that is erected perpendicular to the bottom plate 1a. It is comprised from the 2nd side plate 1c provided in the position which opposes, and the front plate 1d provided so as to be orthogonal to the bottom plate 1a, the 1st side plate 1b, and the 2nd side plate 1c. That is, the case 1 is not a bag-like casing structure surrounded by five or six faces, but a casing structure having wall portions on four of the six faces. The cartridge 200 is housed in a space surrounded by the front plate 1a, the first side plate 1b, the second side plate 1c, and the front plate 1d. Further, the main surface of the bottom plate 1a has an area larger than the projected area of the cartridge 200 to be stored in the case 1, and the case 1 of the present embodiment is a case for storing a cartridge compliant with the BD standard. The area of the bottom plate 1a is formed larger than the area of the main plane of the BD cartridge (for example, the surface having the opening 102a shown in FIG. 26). The height of the first side plate 1b, the second side plate 1c, and the front plate 1d from the bottom plate 1a is at least equal to or greater than the thickness of the cartridge 200.

  The protrusion 2 is a member capable of pressing the shutter lock member 204 in the cartridge 200 when the cartridge 200 is stored in the case 1. The rib 2 is erected toward the inside of the case 1 on the first side plate 1 b of the case 1. The rib 2 is continuously formed along the longitudinal direction of the first side plate 1b. One end of the rib 2 in the longitudinal direction is positioned in the vicinity of the boundary between the first side plate 1b and the front plate 1d, and the other end is formed halfway in the longitudinal direction of the first side plate 1b. In addition, the rib 2 has a so-called bowl shape in which the top is curved, but is not limited to this shape, and may be a rectangular shape. It is only necessary to have a shape and a width dimension that can be fitted into at least the grooves 214 and 215 formed on the side surface of the cartridge 200. Further, the length of the rib 2 in the longitudinal direction only needs to be extended to a position at which the shutter lock member 204 can be pressed at least when the cartridge 200 is stored in the case 1.

  When the cartridge 200 is stored in the case 1 as described above, the cartridge 200 is stored in the direction shown in FIGS. 2 and 3. That is, the upper half 202 of the cartridge 200 faces the bottom plate 1a, the lower half 203 of the cartridge 200 is exposed, the side surface on which the groove portion 214 of the cartridge 200 is formed faces the second side plate 1c, and the groove portion of the cartridge 200 The cartridge 200 is disposed in the case 1 so that the side surface on which the 215 is formed faces the first side plate 1b. At this time, the rib 2 is located in the groove 215 in the cartridge 200.

  By arranging in this way, the opening 202b formed in the upper half 202 can be covered with the bottom plate 1a, so that foreign matters such as dust can be prevented from entering the cartridge 200.

  Further, since the shutter lock member 204 and the shutter opening / closing member 205 can be covered with the second side plate 1c and the slide member 210 can be covered with the bottom plate 1a, the opening operation of the shutter 216 is not accidentally performed, and the disc It is possible to prevent dust and scratches from adhering to the recording surface 201.

  Next, when taking out the disc 201 from the cartridge 200, the cartridge 200 is stored in the direction as shown in FIG. That is, the lower half 203 of the cartridge 200 faces the bottom plate 1a, the upper half 202 of the cartridge 200 is exposed, the side surface on which the groove portion 215 of the cartridge 200 is formed faces the second side plate 1c, and the groove portion of the cartridge 200 The cartridge 200 is disposed in the case 1 so that the side surface on which 214 is formed faces the first side plate 1b. At this time, the rib 2 is positioned in the groove 214 in the cartridge 200 and presses the shutter lock member 204 in the direction of the arrow M.

  As shown in FIG. 4, by accommodating the cartridge 200 in the case 1, the rib 2 presses the shutter lock member 204, so that the movement restriction of the shutter opening / closing member 205 is released. Next, the pin 211 is removed, and the slide member 210 is unlocked. Thus, the slide member 210 is slidable.

  Next, as shown in FIG. 5, by sliding the slide member 210 in the direction of arrow S, the shutter opening / closing member 205 (see the shutter lock member 105 in FIG. 27) connected to the slide member 210 is moved. 6, the shutter 216 can be shifted to the open state. At the same time, the claw portion 208 can be accommodated in the cartridge 200 as shown in FIG. Thereby, the position restriction of the disk 201 is released.

  In this state, the disc 201 can be removed from the cartridge 200 as shown in FIG. At this time, since the shutter 216 is slightly opened to form the opening 217, when taking out the disk 201 from the cartridge 200, a finger is inserted into the opening 217 from the lower half 203 side of the cartridge 200, and the center hole of the disk 201 is inserted. Since the disc 201 can be lifted while supporting the 201a or the vicinity thereof with a finger, the disc 201 can be easily taken out. This extraction method is merely an example.

  When removing the disk 201 from the cartridge 200, the cartridge 200 is housed in the case 1 and the slide member 210 is slid to release the lock of the disk 201. Then, the cartridge 200 is removed from the case 1 and the disk 201 is removed from the cartridge 200. The disk 201 may be removed from the cartridge 200 with the cartridge 200 stored in the case 1.

  When the disc 201 is stored in the cartridge 200, the disc 201 is placed on the upper surface of the shutter 216 with respect to the cartridge 200 in the state shown in FIG. Next, the slide member 210 is slid in the arrow T direction. When the slide member 210 is slid, the shutter opening / closing member 205 connected to the slide member 210 is moved, the shutter 216 is closed, and the claw portion 208 is moved from the storage position shown in FIG. 5 to the protruding position shown in FIG. To do. As a result, as shown in FIG. 4, the disk 201 is stored in the cartridge 200 and cannot be taken out.

As shown in FIG. 11, when the cartridge 200 is inserted to the back of the case 11 (that is, the position where the tip of the cartridge 200 in the insertion direction is in contact with or close to the front plate 11d), the rib 12 and the shutter lock member 204 are separated from each other. Thus, the shutter lock member 204 is not pressed.

  As described above, in the present embodiment, a predetermined gap is provided between the rib 12 and the boundary portion between the first side plate 11b and the front plate 11d so that the upper half 202 is exposed in the cartridge 200. When the shutter 11 is housed in the case 11, it is possible to avoid a state in which the shutter lock member 204 is constantly pressed by the ribs 12, so that a decrease in elastic restoring force in the shutter lock member 204 can be suppressed.

  Further, when the shutter lock member 204 is constantly pressed and the pin 211 (extraction history pin) of the cartridge 200 is removed, the slide unit 210 may slide unexpectedly and the shutter 208 may be opened. However, according to this configuration, even if the pin 211 is removed, the movement of the slide part 210 can be locked and the opening / closing operation of the shutter 208 can be locked. Therefore, the disk 201 can be protected.

  As described with reference to FIG. 2 in the first embodiment, the case where the cartridge 200 is stored in the case 11 in such a direction that the lower half 203 of the cartridge 200 is exposed is described in the first embodiment. Needless to say, an effect similar to the effect can be obtained.
