20130329540 | 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. | 12-12-2013 |
20130328469 | LIBRARY DEVICE AND ACCESSOR DEVICE - A library device includes: a housing having a substantially rectangular parallelepiped shape, the housing having a first surface and a second surface differing from each other; a first track that is provided within the housing, the first track extending along the first surface; a second track that is provided within the housing, the second track extending along the second surface, the second track being parallel with the first track; and an accessor device that includes a first portion engaging with the first track, and a second portion engaging with the second track. | 12-12-2013 |
20130328396 | POWER SUPPLY STATE MONITORING DEVICE, POWER SUPPLY STATE MONITORING METHOD, AND PROGRAM - Provided is a power supply state monitoring device and so on which is capable of notifying a user of the fact that there is a problem with an AC cord and the fact that a power supply apparatus itself is not mounted separately. The power supply state monitoring device is a device which is provided in a main body of an apparatus in which a first power supply apparatus including an AC cord and a second power supply apparatus including an AC cord can be mounted, and monitors the state of power to be supplied from the second power supply apparatus to the main body of the apparatus when power is supplied from the first power supply apparatus to the main body of the apparatus, determines whether or not the second power supply apparatus is mounted in the main body of the apparatus based on a power-supply mount-state notification signal from the second power supply apparatus, if the second power supply apparatus is mounted in the main body of the apparatus, determines whether or not the power is supplied from the AC cord of the second power supply apparatus based on an AC-supply state notification signal from the second power supply apparatus, and if the power is not supplied from the AC cord, notifies a user of the fact that the second power supply apparatus is mounted in the main body of the apparatus and the power is not supplied from the AC cord. | 12-12-2013 |
20130208320 | USING DEVICE, CONTROL METHOD, AND PROGRAM - A consumable product ( | 08-15-2013 |
20130201810 | LIBRARY DEVICE - (JA) The present invention makes it possible, in a library device capable of containing magazines in a two-tier manner, to simultaneously eject two magazines by a simple mechanism with a reduced number of constituent parts. | 08-08-2013 |
20130194700 | LIBRARY DEVICE, ACCESSOR, AND METHOD OF POSITIONING FOR LIBRARY DEVICE - A library device including the magazine which provides with a plurality of cells for storing the recording medium and the accessor which is positioned at a position facing a target cell in the magazine to pick up the recording medium from the cell or store the recording medium in the cell, the accessor includes a first position correction unit and a second position correction unit which positions the accessor at the position facing the target cell and when the first position correction unit fail to position the accessor at the position facing the target cell, the second position correction unit position the accessor at the position facing the target cell. | 08-01-2013 |
20130186215 | GEAR DRIVE MECHANISM AND LIBRARY DEVICE - It is possible to reduce influence of backlash effectively and to carry out precise position control even if a drive mechanism uses rotary drive of gears. For this, in moving a subject to be moved by rotation of the gears, an original point for position control is positioned by use of a sensor flag, and afterward the position control is carried out. When positioning, a bias means generates a bias in a moving direction for movement to be moved that backlash of gear drive may be removed. This sets the backlash to substantial “zero” in positioning the original point, and stabilizes an original point reset position. | 07-25-2013 |
20130057979 | LIBRARY DEVICE, CONTROL METHOD AND PROGRAM - A library device in which, even if the relation between the number of pulses of a stepping motor and an encoder count number changes, a movement distance of a medium transfer means can be verified by an encoder count number counted by an encoder sensor is provided. | 03-07-2013 |
20130010581 | LIBRARY DEVICE - Disclosed is a library device in which the space to enlarge the magazine can be secured to the rear side of the library device. | 01-10-2013 |
20120294127 | MEDIUM DELIVERY CONTROL APPARATUS, MEDIUM DELIVERY CONTROL METHOD AND PROGRAM - Provided is a medium delivery control apparatus that can prevent the wear of a means relating to the delivery of a recording medium and extend the life of the delivery means. The medium delivery control device controls a medium delivery means for connecting, disconnecting and delivering the recording medium with respect to a deep cell, and includes a first detection recording means for detecting and recording the storage or non-storage of the recording media and the identity of the recording media being stored for each deep cell, a second detection recording means for detecting and recording the number of insertions and removals of the recording medium for each deep cell, a storage point candidate searching means for searching for a storage point candidate cell on the basis of the recording of the first detection recording means, a number-retrieval determining means for retrieving the number of insertions and removals of the recording media at the retrieved storage point candidate cell and determining whether the number exceeds a threshold on the basis of the recording of the second detection recording means, and a medium-delivery control means for controlling the medium delivery means such that the recording medium is delivered to the retrieved storage point candidate cell if the threshold is not exceeded. | 11-22-2012 |
20120250188 | HEAD-CLEANING DEVICE AND HEAD-CLEANING METHOD - A head-cleaning device cleans the surface of a head for reading and writing data from/to a medium, and includes a cleaning unit that moves in parallel with grooves provided in the surface of the head while abutted to the grooves, and thereby cleans the surface of the head. | 10-04-2012 |
20120081814 | Magnetic head cleaning mechanism and a magnetic tape apparatus - In a magnetic head cleaning mechanism applicable to a magnetic tape apparatus using a threading system, a cleaning member is placed at a cleaning position with high precision without excessively pushing the cleaning member. For this purpose, an arm to move a cleaning bristle to clean a magnetic head is disposed at a position on a side of the magnetic head relative to a threader track. The bristle moves through a moving path guided by a cam groove. The bristle first moves toward the threader track and then toward the cleaning position in front of the magnetic head. During the movement to approach the magnetic head through the moving path, the bristle does not exceed the cleaning position. | 04-05-2012 |
