(Second Embodiment)
FIG. 2 is a plan view showing a library apparatus according to the second embodiment. It shows a state viewed from above with the top plate of the housing removed. The library apparatus includes a magazine 100, a housing 200, a front panel 300, a storage / discharge cell unit 400, a magazine lock lever 500, a cover 600, a cover lock 700, a connecting rod 800, and an accessor 900. ing.

  The magazine 100 has a plurality of cells that accommodate cartridges containing recording media.

  The housing | casing 200 has an opening part and accommodates the said magazine through an opening part. The casing 200 is provided with rails 210 so that the magazine 100 can be slid in the direction from the opening toward the depth. In the following description, the description regarding the rail 210 is omitted.

  The front panel 300 has a grip opening 310 for the grip means to enter the housing 200 and covers the opening of the housing 200.

  The accommodation / discharge cell unit 400 is coupled to the front panel 300 and accommodates and discharges some cells of the magazine 100. The accommodation / discharge cell unit 400 includes, for example, a bottom plate fixed to the front panel 300 and an accommodation / discharge cell fixed to the bottom plate and inserted into the magazine 100. In the state where the storage / discharge cell unit 400 is inserted, for example, the storage / discharge cells can be arranged so that the cells fixed to the magazine 100 and the storage / discharge cells are integrally aligned.

  The magazine lock lever 500 can lock the magazine 100 to the housing 200 by the tip of the magazine lock lever 500 coming into contact with a part of the magazine 100. In the example of FIG. 2, the magazine lock lever 500 has an L shape, and a rotation shaft 510 for rotating in a plane parallel to the bottom plate forming the bottom surface of the housing, and the magazine lock lever 500 are attached to the lock side. A spring 520 is provided. Note that the object of the present embodiment can be achieved even if a mechanism for independently moving the magazine lock lever 500 is provided. However, the mechanism can be simplified by using the accessor 900 and the spring 520 without providing a unique mechanism. Therefore, hereinafter, a configuration using the spring 520 will be described.

  The cover 600 is a plate-like member that operates so as to prevent the gripping means from entering the housing 2 from the grip opening 310 in the closed state and to allow the gripping means to enter in the open state. The cover 600 is supported by the cover holder 620 via the rotation shaft 610. Cover holder 620 is fixed to case 200 side of front panel 300. Although not illustrated, a spring biasing force is applied to the cover 600, and the cover 600 is opened when there is no pressure on the cover lock 700. Note that the open state means that the cover 600 rotates in a direction perpendicular to the paper surface of FIG.

  Cover lock 700 controls opening and closing of cover 600. The cover lock 700 is a rod-like member fixed to the cover lock slider 710, and opening and closing is controlled by pressing or not pressing the upper surface of the cover 600 according to the slide of the cover lock slider 710. The cover lock slider 710 slides along the rail 720 and is biased in a direction in which the cover lock 700 does not press the cover by the biasing force of the spring 730.

  The connecting rod 800 is a rod-shaped member having one end abutting against the magazine lock lever 500 and the other end abutting against the cover lock slider 710, and can be slid in parallel with the front panel 300.

  The side of the connecting rod 800 that contacts the magazine lock lever 500 has an arcuate outer shape. Further, since the side surface of the magazine lock lever 500 that contacts here also has an arcuate outer shape, the connecting rod 800 slides smoothly in response to the rotation of the magazine lock lever 500.

  The end of the connecting rod 800 on the side in contact with the cover lock slider 710 has an oblique side surface (as viewed from above in FIG. 2) with respect to the long side of the connecting rod 800, Make sliding contact with one end. For this reason, one end of the cover lock slider 710 also has an oblique side surface with respect to its own sliding direction. As is apparent from the arrangement of FIG. 2, when the connecting rod 800 moves to the cover lock slider 710 side, the cover lock slider 710 slides to the front panel 300 side, and in the opposite case, the biasing force of the spring 730 To move to the other side. Therefore, when the magazine lock lever 500 rotates to the lock side, the connecting rod 800 moves the cover lock slider 710 to the front panel 300 side, the cover lock 700 presses the cover 600, and the cover is closed. Conversely, when the magazine lock lever 500 rotates to the release side, the cover lock slider 710 moves to the magazine 100 side by the biasing force of the spring 730, and the cover is opened.

  The accessor 900 accesses the cell of the magazine 100 to store, take out, and carry the cartridge. Specifically, it can be composed of a main body that moves in the depth direction of the housing and a robot hand (picker) that accesses the cell.

  Next, the operation of the library apparatus will be described. FIG. 3 is a plan view showing a state where the magazine 100 and the storage / discharge cell unit 400 are loaded in the housing 200 and the magazine 100 is locked. When the accessor 900 is not pushing the magazine lock lever 500, the magazine lock lever 500 is arranged to lock the magazine 100 by the biasing force of the spring 520. At this time, the magazine lock lever 500 pushes the connecting rod 800 toward the cover lock slider 710, so that the cover lock slider 710 moves toward the front panel 300 and the cover lock 700 closes the cover 600.

  FIG. 4 is a plan view showing a state in which the magazine 100 is unlocked. The arrows in the figure indicate the movement directions when the respective elements shift from the state of FIG. 3 to the state of FIG. First, the accessor 900 moves to the front panel 300 side, and the magazine lock lever 500 is rotated clockwise in FIG. Then, the pressure from the magazine lock lever 500 is not applied to the connecting rod 800. As a result, the cover lock slider 710 does not receive pressure from the connecting rod 800 and moves to the magazine 100 side by the biasing force of the spring 730. Accordingly, the cover lock 700 does not press the cover 600, so that the cover 600 is opened by the biasing force of the spring. Note that the shapes and arrangements of the cells and cartridges shown here are merely examples, and the present invention is not limited to these. Further, the number of magazines 100 is not limited to one. For example, a configuration in which other magazines are connected in the depth direction of the magazine 100 can be taken.

  FIG. 5 is a cross-sectional view taken along line V-V in FIG. The magazine 100 has a plurality of cells, and a cartridge 120 is accommodated in each cell. The storage / discharge cell unit 400 is inserted into the opening side of the housing 200 of the magazine 100. In this example, the storage / discharge cell 410 is arranged at the lowest front side of the magazine 100. In the magazine lock state of FIG. 5, since the cover lock slider 710 has moved to the front panel 300 side, the cover lock 700 presses the cover 600 from above and closes. In the closed state, the magazine gripping part 110 cannot be gripped even if the gripping means enters from the gripping opening 310. That is, the magazine 100 cannot be pulled out.

  6 is a cross-sectional view taken along line VI-VI in FIG. In the magazine lock release state, the cover lock slider 710 is slid toward the magazine 100, so the cover lock 700 does not press the cover 600. In this case, the cover 600 is rotated in a direction standing above the paper surface by the biasing force of the spring 630 and is in an open state. In the open state, the magazine gripping portion 110 can be gripped together with the front panel 300 by inserting gripping means from the gripping opening portion 310.

  As described above, according to the present embodiment, a simple mechanism interlocks magazine locking and cover opening / closing, and only a part of cells can be operated, and the whole magazine can be operated. And can be switched.

(Third embodiment)
In the present embodiment, a specific operation and operation example of the library apparatus will be described. FIG. 7 is a block diagram illustrating an example of a library apparatus. The library apparatus includes a housing 200, a front panel 300, an accessor 900, and a drive device 1000. The magazine 200 is loaded in the housing 200. Here, an example is shown in which the magazine 100 has a configuration in which the magazine 100 a and the magazine 100 b are connected by the connecting means 130. Although not shown, a mechanism for controlling the connecting means 130 from the outside, a mechanism for urging the magazine 100 toward the opening, and the like may be provided. A storage / discharge cell unit 400 is loaded on the front panel 300 side of the magazine 100a. The accommodating / discharging cell unit 400 is in contact with an urging means 140, and the accommodating / discharging cell unit 400 can be locked and urged toward the opening of the housing 200 by external control. The accessor 900 can access an arbitrary cell of the magazine 100 and the drive device 1000, and can carry a cartridge between them. The drive device 1000 reads / writes the loaded cartridge. The details of each component described above are the same as those in the second embodiment.

  Next, an operation for loading the entire magazine will be described. FIG. 8 is a plan view showing a state during loading of the magazine.

  On the housing 200 side, the accessor 900 presses the magazine lock lever 500 and the magazine lock is released. In the storage / discharge cell unit 400, the cover lock slider 710 is slid to the lock release side by the biasing force of the spring 730. For this reason, the cover 600 is in an open state, and the gripping means can grip the magazine gripping part 110 and the front panel 300 simultaneously. And the accommodation discharge cell unit 400 and the magazine 100 can be loaded integrally.

  FIG. 9 is a plan view showing a state where loading of the magazine 100 and the storage / discharge cell unit 400 is completed. At this time, since the accessor 900 has not moved, the magazine lock lever 500 does not press the connecting rod 800. For this reason, the cover 600 is still open.

  FIG. 10 is a plan view showing a state in which the magazine 100 is locked from the state of FIG. Since the accessor 900 releases the press of the magazine lock lever 500, the magazine lock lever 500 rotates around the radius of the paper surface by the urging force of the spring 520, and moves the connecting rod 800 to the cover lock 700 side. As a result, the connecting rod 800 moves the cover lock slider 710 toward the front panel 300, the cover lock 700 presses the cover 600, and the cover 600 is closed. Thus, the loading of the magazine 100 is completed.

  Based on the above description, the operation when the magazine is discharged and loaded will be described. FIG. 11 is a flowchart showing the operation of the library apparatus and the operation procedure of the operator when the magazine is ejected and reloaded. First, the accessor presses the magazine lock lever to unlock the magazine (S101). By this operation, the cover is opened (S102). The operator grips the front panel and the magazine gripping unit integrally (S103). Next, the magazine is pulled out, and the magazine is discharged from the library apparatus (S104). Here, the operator can exchange cartridges or magazines. Then, the magazine is inserted into the library device (S105). At this time, since the cover is in an open state, the operator can hold the magazine integrally with the front panel. When the insertion of the magazine is completed, the accessor moves and presses the magazine lever to lock the magazine (S106). By this operation, the cover is closed (S017), and the operation is completed.

  Next, the operation for discharging and loading the storage / discharge cell unit will be described. FIG. 12 is a plan view showing a state immediately after the discharge of the storage / discharge cell unit 400 is started. The magazine 100 is locked by a magazine lock lever 500. The accommodation / discharge cell unit 400 and the front panel 300 are moved in a direction of being discharged from the opening of the housing 200 by a biasing means (not shown). Immediately after discharging, the connecting rod 800 moves a small amount toward the accessor 900 while contacting the magazine lock lever 500. For this reason, the opening of the cover 600 slightly approaches the open state from the closed state. At this time, since the gripping means cannot grip the magazine gripping part 110, no force is accidentally applied to the magazine. As the discharge proceeds, the connecting rod 800 further moves to the accessor side, and the pressing of the cover lock 700 against the cover is gradually released. When the cover 600 is opened until a certain point in time, the cover 600 comes into contact with the magazine gripping portion 110, and the opening of the cover is limited by this contact. When the discharge further proceeds, the cover 600 is opened.

  FIG. 13 is a plan view showing a state in which the discharge of the storage / discharge cell unit 400 has progressed and the cover 600 is opened. The cover 600 is in an open state because there is no pressure received from the cover lock 700 and the magazine gripping part 110. For this reason, the operator can hold the front panel and take out the storage / discharge cell unit 400 completely. By removing the storage / discharge cell unit 400, the cartridge stored in the storage / discharge cell 410 can be operated.

  Based on the above description, the operation when the accommodation / discharge cell unit is discharged / loaded will be described. FIG. 14 is a flowchart showing the operation of the library apparatus and the operation procedure of the operator when the storage / discharge cell unit is discharged and loaded again. First, the accessor moves to release the magazine lock lever and lock the magazine (S201). By this operation, the cover is closed (S202). The operator operates the biasing means of the storage / discharge cell unit to move the storage / discharge cell unit in the discharge direction (S203). Then, the cover is gradually opened in conjunction with the movement of the storage / discharge cell unit (S204). When the cover is opened, the operator inserts gripping means from the gripping opening, grips the front panel, and pulls out the storage / discharge cell unit (S205). By taking out the storage / discharge cell unit from the library apparatus in this way, for example, the cartridge stored in the storage / discharge cell can be replaced. Then, the storage / discharge cell unit is inserted into the library device again (S207). The cover is gradually closed in conjunction with the movement of the storage / discharge cell unit in the insertion direction (S208). Until the cover is closed, the operator pulls out the gripping means from the gripping opening, and thereafter pushes the front panel to load the storage / discharge cell unit. Finally, the urging means is operated to lock the storage / discharge cell unit and the operation is completed (S209).

  As described above, according to the present embodiment, the library apparatus can be operated by switching between the operation on the entire magazine and the operation on only a part of the cells reliably and safely by a simple mechanism and operation. Can do.

  The present invention has been described above using the above-described embodiment as an exemplary example. However, the present invention is not limited to the above embodiment.
