A printer includes a cap member, a head, a suction pump, a first electromagnetic valve, and a waste liquid flow path including a first flow path portion and a second flow path portion. The cap member seals a discharge surface in the head. The suction pump is connected to the waste liquid flow path and puts it into a negative pressure state. The first electromagnetic valve connects the cap member and the suction pump, cuts off the connection between the cap member and the waste liquid flow path, and includes a first wall portion. The first wall portion includes a side face portion on which an inflow opening and an outflow opening are formed. The inflow opening connects to the first flow path portion. The outflow opening connects to the second flow path portion and is disposed farther in the direction of the force of gravity than the inflow opening. |

1. A printer, comprising:
at least one head that includes a discharge surface that is provided with a nozzle that is configured to discharge a liquid; at least one cap member that is configured to move between a sealing position and a retracted position, the sealing position being a position where the at least one cap member seals the discharge surface, and the retracted position being a position where the at least one cap member has retracted from the discharge surface; at least one movement device that moves the at least one cap member; at least one waste liquid flow path that is provided with a first flow path portion and a second flow path portion; at least one suction pump that is connected to the at least one waste liquid flow path and that is configured to put the at least one waste liquid flow path into a negative pressure state; and a first electromagnetic valve that is provided in the at least one waste liquid flow path, that is connected to the at least one cap member by the first flow path portion, that is connected to the at least one suction pump by the second flow path portion, that is configured to cut off the connection between the at least one cap member and the at least one waste liquid flow path, and that is provided with a first wall portion, a first valve member, a first energizing member, and a first drive portion,
the first wall portion including a side face portion on which are formed an inflow opening, an outflow opening, and a connecting groove, the inflow opening connecting to the first flow path portion, the outflow opening connecting to the second flow path portion and being disposed farther in the direction of the force of gravity than is the inflow opening, and the connecting groove connecting the inflow opening and the outflow opening,the first valve member being configured to shift between a first blocking orientation and a first open orientation, the first blocking orientation being an orientation in which the first valve member blocks the connecting groove by being disposed in a position where it is opposite the side face portion and covers the connecting groove, and the first open orientation being an orientation in which the first valve member opens the connecting groove,the first energizing member imparting to the first valve member a first elastic force that shifts the first valve member to the first blocking orientation, andthe first drive portion shifting the first valve member from the first blocking orientation to the first open orientation in opposition to the first elastic force. |
