Library apparatus, magazine insertion detection method, and program
An exemplary object is to provide a library apparatus, a magazine insertion detection method, and a program that are capable of detecting whether or not a magazine is inserted for all the magazine insertion positions without using sensors for detecting insertion of magazines. A library apparatus includes: a mark reading unit which is provided in an accessor unit which transfers a plurality of media that can be read and written by a computer, and reads a predetermined mark for all insertion positions of a plurality of magazines which can be inserted into the library apparatus and can accommodate the media, the mark being stuck to each of cells accommodating the media; and a control unit which, if the mark can be read, determines that a magazine is inserted at an insertion position which includes a read position for which a reading result that the mark can be read has been obtained, and, if the mark cannot be read, determines that no magazine is inserted at an insertion position which includes a read position for which a reading result that the mark cannot be read has been obtained.
1. A library apparatus comprising:
a mark reading unit which is provided in an accessor unit which transfers a plurality of media that are read and written by a computer, and reads a predetermined mark for all insertion positions of a plurality of magazines which are inserted into the library apparatus and accommodate the media, the mark being stuck to each of cells accommodating the media; and
a control unit which, if reading the mark has succeeded, determines that a magazine is inserted at an insertion position which includes a read position for which a reading result, that the reading of the mark has succeeded, has been obtained, and, if the reading of the mark has failed, determines that no magazine is inserted at an insertion position which includes a read position for which a reading result, that the reading of the mark has failed, has been obtained,
wherein when a determination has been made that no magazine is inserted at a predetermined insertion position, the control unit performs notification of the fact that no magazine is inserted.
2. The library apparatus according to claim 1 , wherein when a determination has been made that no magazine is inserted at a predetermined insertion position, the control unit does not perform inventory on the magazine at the insertion position.
3. The library apparatus according to claim 1 , wherein the mark reading unit reads a mark stuck to a cell at a predetermined position among a plurality of marks stuck to the cells, for each of the magazines.
4. The library apparatus according to claim 1 , wherein the mark reading unit is a camera which is used for reading a recording code stuck to a medium when inventory is performed.
5. The library apparatus according to claim 1 , wherein the mark is a target mark which is stuck to a latch lever that is provided around an insertion slot for a medium in a cell and is read when the accessor unit is located.
6. The library apparatus according to claim 2 , wherein the mark reading unit reads a mark stuck to a cell at a predetermined position among a plurality of marks stuck to the cells, for each of the magazines.
7. The library apparatus according to claim 2 , wherein the mark reading unit is a camera which is used for reading a recording code stuck to a medium when inventory is performed.
8. The library apparatus according to claim 3 , wherein the mark reading unit is a camera which is used for reading a recording code stuck to a medium when inventory is performed.
9. The library apparatus according to claim 6 , wherein the mark reading unit is a camera which is used for reading a recording code stuck to a medium when inventory is performed.
10. The library apparatus according to claim 2 , wherein the mark is a target mark which is stuck to a latch lever that is provided around an insertion slot for a medium in a cell and is read when the accessor unit is located.
11. The library apparatus according to claim 6 , wherein the mark is a target mark which is stuck to a latch lever that is provided around an insertion slot for a medium in a cell and is read when the accessor unit is located.
12. The library apparatus according to claim 4 , wherein the mark is a target mark which is stuck to a latch lever that is provided around an insertion slot for a medium in a cell and is read when the accessor unit is located.
13. The library apparatus according to claim 6 , wherein the mark is a target mark which is stuck to a latch lever that is provided around an insertion slot for a medium in a cell and is read when the accessor unit is located.
14. The library apparatus according to claim 7 , wherein the mark is a target mark which is stuck to a latch lever that is provided around an insertion slot for a medium in a cell and is read when the accessor unit is located.
15. The library apparatus according to claim 8 , wherein the mark is a target mark which is stuck to a latch lever that is provided around an insertion slot for a medium in a cell and is read when the accessor unit is located.
16. The library apparatus according to claim 9 , wherein the mark is a target mark which is stuck to a latch lever that is provided around an insertion slot for a medium in a cell and is read when the accessor unit is located.
17. A magazine insertion detection method comprising:
reading, by a mark reading unit which is provided in an accessor unit which transfers a plurality of media that are read and written by a computer, a predetermined mark for all insertion positions of a plurality of magazines which are inserted into an apparatus and accommodate the media, the mark being stuck to each of cells accommodating the media;
determining, if reading of the mark has succeeded, that a magazine is inserted at an insertion position which includes a read position for which a reading result, that the reading of the mark has succeeded, has been obtained;
determining, if the reading of the mark has failed, that no magazine is inserted at an insertion position which includes a read position for which a reading result, that the reading of the mark has failed, has been obtained; and
when a determination has been made that no magazine is inserted at a predetermined insertion position, performing notification of the fact that no magazine is inserted.
18. A non-transitory computer-readable recording medium storing a program which causes a computer to execute:
a reading process of reading, by a mark reading unit which is provided in an accessor unit which transfers a plurality of media that are read and written by the computer, a predetermined mark for all insertion positions of a plurality of magazines which are inserted into an apparatus and accommodate the media, the mark being stuck to each of cells accommodating the media; and
a determination process of determining, if reading the mark has succeeded, that a magazine is inserted at an insertion position which includes a read position for which a reading result, that the reading of the mark has succeeded, has been obtained, and determining, if the reading of the mark has failed, that no magazine is inserted at an insertion position which includes a read position for which a reading result, that the reading of the mark has failed, has been obtained;
wherein when a determination has been made that no magazine is inserted at a predetermined insertion position, the determination process performs notification of the fact that no magazine is inserted.
