Abstract

A recording apparatus includes a conveyance unit that conveys a recording medium in a first direction toward a recording head for ejecting a liquid, a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction, a rotatable lever that holds a tank cap for closing the injection port, and a cover that rotates about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction. The cover includes a sliding portion that is provided on a surface facing the lever and comes into contact with the lever while the cover is rotating toward the closed position.

Claims (15)

1. A recording apparatus comprising:

a conveyance unit configured to convey a recording medium in a first direction toward a recording head for ejecting a liquid;

a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction;

a lever configured to rotate and hold a tank cap for closing the injection port; and

a cover configured to rotate about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction,

wherein the cover includes a sliding portion provided on a surface facing the lever, and configured to come into contact with the lever while the cover is rotating toward the closed position.

2. The recording apparatus according to claim 1 , wherein, in a case where the lever comes into contact with the sliding portion, the lever is urged toward a position where the tank cap closes the injection port.

3. The recording apparatus according to claim 1 , further comprising a holding portion configured to hold the lever at a holding position where the tank cap is away from the injection port.

4. The recording apparatus according to claim 3 , wherein, while the lever is moving toward the holding position, the lever comes into contact with the holding portion and becomes elastically deformed, so that the lever is held by the holding portion.

5. The recording apparatus according to claim 3 , wherein the sliding portion has a curved surface where an angle between a gravity direction and a normal at a contact point with the lever at the holding position is larger than an angle between the gravity direction and a straight line connecting the contact point and a rotation shaft of the lever.

6. The recording apparatus according to claim 3 , wherein, in a state where the lever is not held by the holding portion and the injection port is not closed by the tank cap, while the cover is rotating toward the closed position, the sliding portion comes into contact with the lever.

7. The recording apparatus according to claim 1 , wherein the cover includes a reading unit configured to read an image of an original document.

8. The recording apparatus according to claim 1 , wherein the lever is color-coded in a color corresponding to a color of the liquid contained in the tank.

9. The recording apparatus according to claim 1 , wherein an opening portion is formed between the cover and a housing of the recording apparatus, and the lever is visually recognizable through the opening portion while the cover is in the closed position.

10. The recording apparatus according to claim 1 , wherein the tank is disposed on a downstream side in the first direction in the recording apparatus.
