## Abstract

A printing apparatus includes a liquid storing container including a storage chamber configured to store a liquid supplied to a printing unit that prints an image by discharging the liquid, an outlet portion of the liquid, and a channel configured to connect the storage chamber and the outlet portion. The liquid storing container includes a first side portion on a side of a print region where printing is executed by the printing unit, and a second side portion on an opposite side of the first side portion, and the channel is formed in the second side portion.

## Claims

### Claim 1

A printing apparatus comprising a liquid storing container including a storage chamber configured to store a liquid supplied to a printing unit that prints an image by discharging the liquid, an outlet portion of the liquid, and a channel configured to connect the storage chamber and the outlet portion,
wherein the liquid storing container includes a first side portion on a side of a print region where printing is executed by the printing unit, and a second side portion on an opposite side of the first side portion, and
the channel is formed in the second side portion.

### Claim 2 (depends on 1)

The printing apparatus according to claim 1, wherein an end, on a side of the storage chamber, of the channel is located above a liquid surface of the liquid in the storage chamber in a case where the printing apparatus is in a posture in which the second side portion is set on an upper side in a state in which a maximum amount of the liquid is stored in the storage chamber.

### Claim 3 (depends on 1)

The printing apparatus according to claim 1, wherein an end, on a side of the storage chamber, of the channel is located above a liquid surface of the liquid in the storage chamber in a case where the printing apparatus is in a posture in which a front portion of the printing apparatus is set on an upper side in a state in which a maximum amount of the liquid is stored in the storage chamber.

### Claim 4 (depends on 1)

The printing apparatus according to claim 1, wherein the outlet portion is located above a liquid surface of the liquid in the storage chamber in a case where the printing apparatus is in a posture in use in a state in which a maximum amount of the liquid is stored in the storage chamber.

### Claim 5 (depends on 1)

The printing apparatus according to claim 1, wherein the outlet portion is located above a liquid surface of the liquid in the storage chamber in a case where the printing apparatus is in a posture in which a front portion of the printing apparatus is set on a lower side in a state in which a maximum amount of the liquid is stored in the storage chamber.

### Claim 6 (depends on 1)

The printing apparatus according to claim 1, wherein
the liquid storing container includes a protruding portion forming the second side portion and protruding to a window portion formed in an outer wall portion of the printing apparatus, and
the protruding portion has transparency.

### Claim 7 (depends on 1)

The printing apparatus according to claim 1, wherein
the storage chamber is defined by a peripheral wall portion including an opening and a first sealing member configured to seal the opening, and
the opening and the sealing member are arranged in the first side portion.

### Claim 8 (depends on 7)

The printing apparatus according to claim 7, wherein
the liquid storing container includes a forming member configured to form the peripheral wall portion and the outlet portion, and
the channel includes a groove formed in the forming member and a portion formed by a second sealing member configured to seal the groove.

### Claim 9 (depends on 7)

The printing apparatus according to claim 7, wherein
a part of the peripheral wall portion forms the second side portion, and
an end, on a side of the storage chamber, of the channel opens to the part of the peripheral wall portion.

### Claim 10 (depends on 1)

The printing apparatus according to claim 1, wherein the liquid storing container includes an injection portion configured to inject the liquid to the storage chamber.

### Claim 11

A printing apparatus comprising a first liquid storing container and a second liquid storing container each including a storage chamber configured to store a liquid supplied to a printing unit that executes printing by discharging the liquid, an outlet portion of the liquid, and a channel configured to connect the storage chamber and the outlet portion,
wherein the first liquid storing container includes a first side portion on a side of a print region where printing is executed by the printing unit, and a second side portion on an opposite side of the first side portion,
the channel of the first liquid storing container is formed in the second side portion,
the second liquid storing container includes a third side portion on the side of the print region, and a fourth side portion on an opposite side of the third side portion,
the channel of the second liquid storing container is formed in the fourth side portion,
the first liquid storing container is located on a left side of the printing apparatus in a left-and-right direction of the printing apparatus,
the second liquid storing container is located on a right side of the printing apparatus in the left-and-right direction, and
the print region is located between the first liquid storing container and the second liquid storing container in the left-and-right direction.

### Claim 12
