  • the cartridge will not move around inside the cartridge holding component, but since this requires extremely high precision, it is generally much more advantageous in terms of manufacturing cost to provide a latching member that latches the cartridge to a side wall of the cartridge holding component across from the cartridge.
  • This latching member is equipped with a fixing engagement component that engages either with the side wall of the cartridge holding component across from the cartridge, or with the bottom panel of the main body, generates a biasing force with respect to the cartridge, and fixedly engages this cartridge.
  • the means for generating the biasing force can be, for example, a leaf spring, a coil spring, or another such biasing means, but since this biasing means and the fixing engagement component require the assembly of independent parts made of different materials, this can lead to an increase in the required numbers of parts and manufacturing steps. Therefore, it is generally preferable for the biasing means to be made of the same resin material that makes up the main body, and to utilize the viscoelasticity of this resin material, because this allows the latching member to be formed simultaneously with the main body.
  • the fixing engagement component may be configured, for example, such that it engages with the upper and lower halves of the cartridge and grasps the cartridge in its thickness direction, or configured such that it presses against the cartridge side walls with a curved or flat surface, or configured such that it presses on and engages with a groove portion provided at the cartridge side end face.

  • the release component prefferably be provided in the vicinity of at least one of the latching components because the cartridge will be subjected to less deformation related to the position and force applied to the cartridge during release and engagement. It is also preferable for the height from the bottom of the pressure release component to be less than the thickness of the cartridge being held, because it will be easier to grasp the cartridge that has been lifted by the engagement release component when pressure is applied to the pressure release component.
  • a lid that covers the main body prefferably covers the main body to be provided on the side on which a cartridge is inserted into the cartridge holding component, because this will protect against dust, scratches, and so forth when the cartridge is carried around while held in the case of the present invention, for example.
  • a lid configuration in which the rotational axis is on at least one of the side walls of the main body, and the lid rotates around this rotational axis, is less expensive than a configuration in which the lid is a separate component, and furthermore helps prevent the lid from coming off and being lost.

  • the cartridge 19 when the cartridge 19 is installed in the case 100 , the cartridge 19 is aligned with the corner positioning portion 7 and the forward positioning portions 8 , and the upper half 21 is pressed near the three locations of engagement with the latching components 10 , 11 , and 12 , for example, which allows the cartridge 19 to be installed in the case 100 against the biasing force of the latching components 10 , 11 , and 12 .
  • the latching component 10 is in biased engagement in a groove in which is engaged a tray engagement tab formed on the lower half side wall recess 32 , and the latching components 11 and 12 are in biased engagement in the groove portion 30 , the result being that there is a gap between the bottom panel 2 and the lower half 23 of the cartridge 19 , and the cartridge 19 rests on the pedestals 9 .
  • the pedestals 9 are not absolutely necessary, but it is preferable to provide the pedestals 9 because if the cartridge 19 held in the case 100 is left for a long time with the gap from the bottom maintained only by the biasing force of the latching components 10 , 11 , and 12 , there is the danger that the biasing force on the cartridge 19 could deform the cartridge 19 , and the pedestals 9 prevent this from happening.
  • the upper half 21 is pressed against the biasing force of the latching components 10 , 11 , and 12 , allowing the cartridge 19 to be held by the latching components 10 , 11 , and 12 .
  • the removal of the cartridge 19 from the case 100 will now be described.
  • the cartridge 19 cannot be taken out merely by tilting the case 100 , for example, because the cartridge 19 is biased and latched by the latching components 10 , 11 , and 12 .
  • the cartridge 19 can be pulled out and removed by the reverse procedure from installation.
  • there is not enough room to insert a finger in the gap formed between the side faces of the cartridge 19 and the side faces 3 , 4 , 5 , and 6 of the case body 1 so the cartridge 19 is grasped by inserting a finger along a diagonal of the cartridge 19 .
  • the release member 13 that releases the biasing force produced by the latching component 33 can be provided to the case 100 according to this embodiment, which eliminates the above problem.
  • the release member 13 lifts up the cartridge 19 through the principle of leverage, and the user removes the cartridge 19 by grasping the portion that has been lifted up from the bottom panel 2 of the case 100 . This will be described in detail through reference to FIG. 11B .
  • FIG. 11B is a cross section illustrating the operation of the release member 13 .
  • the release member 13 comprises the engagement release component 35 that serves as the point of leverage application between the bottom panel 2 and the lower half 23 of the cartridge 19 ; the pressure release component 36 that functions as the leverage force point at which acting force is imparted to the engagement release component 35 ; and the linking release component 37 that links the engagement release component 35 and the pressure release component 36 and functions as the leverage fulcrum.
  • the engagement release component 35 is in the gap between the bottom panel 2 and the lower half 23 of the cartridge 19 .
  • this release member 13 is provided in the vicinity of one of the latching components 10 , 11 , and 12 , the latching of just one of the latching components 10 , 11 , and 12 can be selectively released, so the pressing force applied to the pressure release component 36 can be smaller and the latching can be released in a shorter raising distance for the engagement release component 35 than with a configuration in which the release member 13 is provided at the center point between the latching components 11 and 12 as shown in FIG. 8 , for example.
  • FIG. 11B makes the cartridge 19 appear as if it were deformed, but deformation of the cartridge 19 can be suppressed by appropriately adjusting the biasing force of the latching components 10 , 11 , and 12 .
  • FIG. 12A is a plan view illustrating another construction of the release member provided to the case 100 according to this embodiment
  • FIG. 12B is a cross section illustrating another construction of the release member
  • FIG. 12C is a cross section illustrating the operation of another release member.
  • the pressure release component 36 provided as another release member 13 is constructed so as to split in its approximate center when a pressing force F acts toward the bottom panel 2 , and the linking release component 37 is constituted so as to move toward the cartridge 19 . It is preferable to employ a configuration such as this because the pressure release component 36 is pressed a shorter distance and the engagement release component 35 is raised higher.
  • FIGS. 6 and 8 show examples in which this other release member 13 is provided.
  • FIG. 7C is an oblique view schematically illustrating another construction of a case 100 A according to an embodiment. As shown in FIG. 7C , the lid 16 may be connected to the upper side of the side panel 6 .
  • FIG. 7D is an oblique view schematically illustrating yet another constitution of the case according to an embodiment. As shown in FIG. 7D , the lid 16 may be connected to the bottom panel 2 , without providing the side panel 6 .
  • the release member 13 is provided on the bottom panel 2 so as to push up the lower half 23 of the cartridge 19 in order to release the latching of the cartridge 19 by the latching member 11 , which is one of the plurality of latching members 10 , 11 , and 12 . Accordingly, the release member 13 provided to the bottom panel 2 releases the latching of the cartridge 19 produced by the latching member 11 by pushing up the lower half 23 of the cartridge 19 . Therefore, it is possible to provide a case 100 with which external vibration will not cause the cartridge 19 held inside to wobble and make noise, and which can hold a cartridge without placing undue load on the shutters 24 for opening and closing the opening window 25 used to expose the recording side of the disc 20 in its radial direction.
  • the cartridge used in this embodiment has an exposure hole formed in the upper half, but the present invention is not limited to this configuration.
  • the upper half may be in the form of a plate that covers the entire lower half, or an opening window may be provided on the upper and lower halves as with an ordinary cartridge, and both of these types can be held in the case of the present invention. It is preferable to form an exposure hole in the upper half as in this embodiment because information recorded on the disc, such as words or symbols, can be written directly on the disc held in the cartridge, for example, and this written information related to the disc can be viewed while the disc is still held in the cartridge.
  • the cartridge described in this embodiment was configured such that a disc held inside could be taken out by providing a door, but the present invention is not limited to this.
  • the door is not essential, and the case of the present invention also can be applied to a cartridge that does not permit the disc to be removed.
  • the door of the cartridge described in this embodiment was provided to the upper half, but may instead be provided to the side faces of the upper and lower halves.
  • the example described above had two latching components on a side end face of the cartridge, and one on the side face across from the side end face, but the present invention is not limited to this. If one or more latching components are provided to each opposing side face, this will prevent wobble of the installed cartridge. It is preferable for at least a pair of latching components to be disposed at substantially opposite diagonal corners of the cartridge, and for a release component to be provided in the vicinity of a latching component, because this will facilitate the raising of the corner of the cartridge, which is easier to grasp, by the release operation of the release component.
  • a cartridge provided with a short groove in a side face and a long groove in a side end face as in this embodiment, backward installation can be prevented by providing two latching components on the side end face side. If one or more latching components are provided at each of the mutually opposing side faces of the cartridge as above, the cartridge can be held while latched, but it is preferable to employ three latching components as in this embodiment, and provide a release component in the vicinity of one of the two latching components that latch the cartridge side face, because the corner of the unlatched cartridge will be able to move up and down a greater distance, making it easier to grasp and remove.
  • the engagement release component described in the above embodiment was disposed between the bottom and the cartridge, but the present invention is not limited to this.
  • the engagement release component also can be embedded in the bottom.
  • the cartridge can be held while resting on the bottom, which means that the cartridge can be held more stably. This, however, requires a precise fit between the release component and the hole in which the engagement release component is embedded.
  • a cartridge can be latched and held without placing undue load on the shutters, which is effective for eliminating problems such as scratching of the cartridge caused by the cartridge being loosely inserted in the interior of the case while being carried around, or the adhesion of dust or other foreign matter to the cartridge and/or the disc held in the cartridge.
  • the present invention provides a case with which external vibration will not cause a cartridge held inside to wobble and make noise, and which can hold a cartridge without placing undue load on the cartridge shutters.
