The housing includes: a front wall; a rear wall facing the front wall; and a housing side contact, the first reservoir and the second reservoir includes: a liquid flow hole; a first outer wall; and a second outer wall facing the first outer wall, the first tank includes a first flow pipe, and the second tank includes a second flow pipe. The system further includes a circuit board that is disposed on the second outer wall and has a reservoir side contact that contacts the housing side contact. ## Claims ### Claim 1 A system comprising: a reservoir configured to store liquid; a tank including a flow pipe configured to connect to the reservoir; a housing that includes a conveyance path that extends in a depth direction intersecting a height direction of the housing and through which a sheet passes; a liquid discharge head that is disposed inside the housing and configured to eject the liquid supplied from the tank; and a holder that is disposed on one side of the conveyance path inside the housing in a width direction perpendicular to the height direction and the depth direction and has an opening disposed at an upper end of the holder such that the reservoir is configured to be mounted into the holder through the opening to connect to the flow pipe of the tank; wherein the holder includes a front wall that defines a front end of the holder in the depth direction and that has a front opening configured to face the reservoir in a state where the reservoir is mounted into the holder. ### Claim 2 (depends on 1) The system according to claim 1, wherein the reservoir has a translucency area that allows the liquid stored in the reservoir to be visually recognized from the outside of the reservoir, and the translucency area of the reservoir faces the front opening in a state where the reservoir is mounted into the holder. ### Claim 3 (depends on 2) The system according to claim 2, wherein a dimension of the front opening of the front wall of the holder in the width direction is greater than a dimension of the translucency area of the reservoir in the width direction. ### Claim 4 (depends on 1) The system according to claim 1, wherein the flow pipe includes: a liquid flow path configured be supplied with the liquid from the reservoir; and an air flow path configured to supply the air to the reservoir. ### Claim 5 (depends on 4) The system according to claim 4, wherein the liquid flow path and the air flow path are arranged along the depth direction and configured to be connected to the reservoir. ### Claim 6 (depends on 5) The system according to claim 5, wherein the flow pipe includes a partition extending upward between the liquid flow path and the air flow path in the depth direction. ### Claim 7 (depends on 4) The system according to claim 4, wherein the reservoir includes: a through-hole configured to receive the liquid flow path and the air flow path; and a valve movable between a closed position at which the through-hole is closed and an opened position at which the through-hole is open. ### Claim 8 (depends on 1) The system according to claim 1, wherein the holder is configured to receive a plurality of reservoirs including the reservoir, the plurality of reservoirs is arranged along the width direction in the holder in a state where the plurality of reservoirs is mounted to the holder. ### Claim 9 (depends on 1) The system according to claim 1 further comprising: a cover that is movable to a covering position for covering the upper end of the reservoir in a state where the reservoir is mounted to the holder, and to an open position for opening the upper end of the reservoir. ### Claim 10 (depends on 1) The system according to claim 1 further comprising: another reservoir configured to store liquid; another holder that is disposed on the other side of the conveyance path inside the housing in the width direction and has another opening at an upper end of the another holder to mount the another reservoir through the another opening; and another flow pipe configured to enter the another reservoir, positioned in the another holder and extending in the height direction, an upper end of the another flow pipe in the height direction facing the another opening of the another holder, wherein the another holder includes another front wall that defines a front end of the another holder in the depth direction, the another front wall having another front opening configured to face the another reservoir in a state where the another reservoir is mounted to the another holder. ### Claim 11 (depends on 10) The system according to claim 10, wherein a dimension of the another holder in the width direction is greater than a dimension of the holder in the width direction. ### Claim 12 (depends on 10) The system according to claim 10, wherein the another flow pipe includes: another liquid flow path configured to be supplied with the liquid from the another reservoir; and another air flow path configured to supply the air to the another reservoir. ### Claim 13 (depends on 12) The system according to claim 12, wherein the another liquid flow path and the another air flow path are arranged along the depth direction and configured to be connected to the another reservoir. ### Claim 14 (depends on 13) The system according to claim 13, wherein the another flow pipe includes a partition extending upward between the another liquid flow path and the another air flow path in the depth direction. ### Claim 15 (depends on 12) The system according to claim 12, wherein the another reservoir includes: a through-hole configured to receive the another liquid flow path and the another air flow path; and a valve movable between a closed position at which the through-hole is closed and an opened position at which the through-hole is open. ### Claim 16 (depends on 10) The system according to claim 10 further comprising a cover that is movable to a covering position for covering the upper end of the another reservoir in a state where the another reservoir is mounted to the another holder, and to an open position for opening the upper end of the another reservoir.
