Abstract

A cleaning device includes: a cleaning unit that cleans a cleaning section by coming into contact with the cleaning section, the cleaning section being disposed in a transport space through which a medium is transported; a support unit that supports the cleaning unit, the support unit rotating about a rotation center to cause the cleaning unit to pass the cleaning section in a direction along a transporting direction in which the medium is transported; and a removing unit that is disposed upstream of the cleaning section in the transporting direction of the medium and that comes into contact with the cleaning unit to remove a substance adhering to the cleaning unit.

First claim

What is claimed is:

1 . A cleaning device comprising:
a cleaning unit that cleans a cleaning section by coming into contact with the cleaning section, the cleaning section being disposed in a transport space through which a medium is transported; a support unit that supports the cleaning unit, the support unit rotating about a rotation center to cause the cleaning unit to pass the cleaning section in a direction along a transporting direction in which the medium is transported; and a removing unit that is disposed upstream of the cleaning section in the transporting direction of the medium and that comes into contact with the cleaning unit to remove a substance adhering to the cleaning unit.

2 . The cleaning device according to claim 1 ,
wherein the removing unit is disposed in a region through which the cleaning unit passes from an outside to an inside of the transport space.

3 . The cleaning device according to claim 2 , further comprising:
a reservoir unit disposed on an upper surface of the removing unit, the reservoir unit having a recessed shape and being capable of storing the substance.

4 . The cleaning device according to claim 1 ,
wherein the cleaning unit is disposed on a portion of an outer peripheral surface of the support unit in a rotation direction in which the support unit rotates.

5 . The cleaning device according to claim 4 , further comprising:
a guide unit that is supported on the outer peripheral surface of the support unit and that guides the medium in a state such that the guide unit faces the cleaning section.

6 . The cleaning device according to claim 5 ,
wherein the support unit causes the guide unit to continuously face the cleaning section when the medium is transported, and rotates to cause the cleaning unit to pass the cleaning section and clean the cleaning section in a predetermined cleaning period.

7 . A reading device comprising:
a reading unit including a reading portion disposed in a transport space through which a medium is transported, the reading unit reading an image on the medium; a cleaning unit that cleans the reading portion by coming into contact with the reading portion; a support unit that supports the cleaning unit, the support unit rotating about a rotation center to cause the cleaning unit to pass the reading portion in a direction along a transporting direction in which the medium is transported; and a removing unit that is disposed upstream of the reading portion in the transporting direction of the medium and that comes into contact with the cleaning unit, which moves as the support unit rotates, to remove a substance adhering to the cleaning unit.

8 . The reading device according to claim 7 , further comprising:
a calibrating unit that is supported on an outer peripheral surface of the support unit and that calibrates the reading unit in a state such that the calibrating unit faces the reading portion.

9 . The reading device according to claim 8 ,
wherein the calibrating unit includes:
a first calibrating unit having a predetermined color; and
a second calibrating unit having a color that differs from the color of the first calibrating unit.

10 . An image forming apparatus comprising:
a recording unit that records an image on a medium; and the reading device according to claim 7 that reads the image recorded on the medium by the recording unit.

11 . An image forming apparatus comprising:
a recording unit that records an image on a medium; and the reading device according to claim 8 that reads the image recorded on the medium by the recording unit.

12 . An image forming apparatus comprising:
a recording unit that records an image on a medium; and the reading device according to claim 9 that reads the image recorded on the medium by the recording unit.

13 . A cleaning device comprising:
cleaning means for cleaning a cleaning section by coming into contact with the cleaning section, the cleaning section being disposed in a transport space through which a medium is transported; support means for supporting the cleaning means, the support means rotating about a rotation center to cause the cleaning means to pass the cleaning section in a direction along a transporting direction in which the medium is transported; and removing means that is disposed upstream of the cleaning section in the transporting direction of the medium and that comes into contact with the cleaning means to remove a substance adhering to the cleaning means.
