  • Publication number: 20240109340
    Abstract: A transport device including a transporting belt that includes a medium-supportable outer circumferential surface and transports the medium, a cleaning roller capable of cleaning the outer circumferential surface, a storage unit that stores a cleaning liquid supplied to the outer circumferential surface via the cleaning roller, a discharge port through which the cleaning liquid is dischargeable, a flow path pipe through which the discharged cleaning liquid is passable, a pump that changes an internal pressure of the flow path pipe to cause the cleaning liquid to flow so that the cleaning liquid stored in the storage unit is discharged from the storage unit through the discharge port and the flow path pipe, a sensor capable of detecting the internal pressure of the flow path pipe, and a control unit that determines a state of the cleaning liquid stored in the storage unit based on a detection result of the sensor.

  • Patent number: 10534766
    Abstract: A data management apparatus manages a database that has a plurality of items each of which has item attribute data. The data management apparatus includes determining, when an update request to the database is accepted, whether an item that is designated in the update request is included in the items, adding, when the designated item is not included in the items, the designated item to the items, and setting a definition setting flag included in item attribute data of the designated item to a second state that is different from a first state to which a definition setting flag included in item attribute data of an item approved as an item of the database is set.
