An inkjet recording apparatus includes an ink passage member capable of supplying ink from an ink storage unit to a carriage, a passage connecting member capable of connecting the ink passage member to a recording head, an operating member capable of switching the passage connecting member between a connection state where the ink passage member is connected to the recording head and a disconnection state where the ink passage member is disconnected from the recording head, and an operating-member regulating member regulating the operating member. The operating-member regulating member is capable of switching the operating member between a state where switching to the disconnection state by the operating member is permitted and a state where this switching is prevented.

1. Field of the Invention
The present invention relates to an inkjet recording apparatus, and in particular, relates to an inkjet recording apparatus that discharges ink through a recording head removably mounted on a carriage to perform recording.
2. Description of the Related Art
FIG. 1 is a partial perspective view of an inkjet recording apparatus according to an embodiment of the present invention.
FIGS. 2A and 2B are schematic perspective views of a recording head.
FIG. 3 is a schematic perspective view of a carrier unit.
An embodiment of the present invention will be described in detail below with reference to the drawings. In the drawings, the same reference numerals denote the same or equivalent portions. The present invention relates to an inkjet recording apparatus that discharges ink through a recording head to perform recording on a recording medium. The recording head in the present invention includes, for example, an inkjet head cartridge, an inkjet head, an inkjet cartridge, an ink cartridge, or a pen cartridge.
FIG. 1 is a general schematic perspective view of an inkjet recording apparatus according to this embodiment. The inkjet recording apparatus, indicated at 1, roughly includes a sheet feeding section 20, a sheet conveying section 30, a sheet output section 40, a carrier unit 70, a recording head recovering section (recovery unit) 50, and an ink supply unit 60. A recording head 100 is mounted on the carrier unit 70. A host device (not illustrated) transmits recording data. The data is stored by a control unit (not illustrated), disposed on a control substrate (not illustrated), included in the inkjet recording apparatus. The control unit outputs a recording start instruction, thus starting a recording operation.
After the recording operation is started, a sheet feeding operation is first performed. The sheet feeding section 20 includes, for example, an automatic sheet feeder (ASF). The ASF 20 feeds recording sheets, serving as recording media, on a one-by-one basis to the sheet conveying section 30. The fed recording sheet is gradually conveyed by the sheet conveying section (recording medium conveying unit) 30 such that the sheet is moved forward by a predetermined line feed distance without being loosened or pulled.
