Description

Conveying device and recording device Technical Field The present invention relates to a conveying device including a belt (belt) capable of conveying a medium, and a recording apparatus including the conveying device. Background As an example of such a conveying device, there is a conveying device described in patent document 1. The conveying device includes an endless belt 5 for supporting a recording medium P by a surface 5a and conveying the recording medium P in a predetermined conveying direction, a brush roller 7 for cleaning the surface 5a, a spray cylinder 9 for directly spraying cleaning liquid L on the surface 5a of the endless belt 5 passing through a sprayed area S located upstream of the brush roller 7 in the conveying direction, a storage device 10 provided at least below the sprayed area S and the spray cylinder 9 and storing the cleaning liquid L dropped, and a liquid feed pump 12 for feeding the cleaning liquid L stored in the storage device 10 to the spray cylinder 9. The cleaning liquid L is filtered by the filter 12c while circulating through the liquid feed path. In the conveying device described in patent document 1, the filter 12c becomes dirty, and thus needs to be replaced. However, in patent document 1, no consideration is given to replacement of the filter 12 c. Patent document 1 Japanese patent application laid-open No. 2009-241285 Disclosure of Invention In order to solve the above-described problems, a conveyor device according to the present invention includes a conveyor belt having a support surface capable of supporting a medium and capable of conveying the medium, a device body provided with the conveyor belt, a cleaning unit configured to clean the support surface with a liquid, the cleaning unit including a storage unit configured to store the liquid, a flow path member configured to pass the liquid discharged from and flowing back through the storage unit, and a filter unit detachably provided to the flow path member, the filter unit being configured to be pulled out in a direction away from the device body. The recording device according to the present invention is characterized by comprising a recording unit capable of recording on a medium, a conveyor belt having a support surface capable of supporting the medium and capable of conveying the medium, a device body provided with the conveyor belt, a cleaning unit configured to clean the support surface with a liquid, the cleaning unit comprising a storage unit configured to store the liquid, a flow path member configured to pass the liquid discharged from and flowing back through the storage unit, and a filter unit configured to be removably provided on the flow path member, the filter unit being configured to be pulled out in a direction away from the device body. Drawings Fig. 1 is a schematic side view of a main part of a recording apparatus including a conveying apparatus according to embodiment 1 of the present invention. Fig. 2 is an enlarged cross-sectional view of a main part of a part of the cleaning unit according to embodiment 1, as viewed from the X-axis direction. Fig. 3 is an enlarged cross-sectional view of a main part of the cleaning unit according to embodiment 1, schematically viewed from the Y-axis direction. Detailed Description Hereinafter, the present invention will be described first in outline. In order to solve the above-described problems, a first aspect of the present invention provides a conveying device including a conveying belt having a supporting surface capable of supporting a medium and capable of conveying the medium, a device body provided with the conveying belt, a cleaning section configured to clean the supporting surface with a liquid, the cleaning section including a storage section configured to store the liquid, a flow path member through which the liquid discharged from the storage section and flowing back passes, and a filter section provided to be removable from the flow path member, the filter section being configured to be pulled out in a direction away from the device body. Here, the "device main body" includes, for example, a structure in which a plurality of frames are combined. According to this aspect, the filter unit can be pulled out in a direction away from the device body. Thus, by pulling out the filter unit in a direction away from the apparatus main body unit, the filter unit can be displaced to a position where the operation of removing the filter from the filter unit is easy. This can enhance the workability of replacing the filter by the user.
