  • Patent number: 10173432
    Abstract: A decrease in the capacity of an ink tank can be easily avoided while downsizing a printer. A printer includes a printing head, an ink tank, a carriage provided with the printing head movable back and forth, and a medium conveyance device that conveys a printing medium on a conveyance path intersecting the carriage moving direction. An axis line along the carriage moving direction is an X axis and an axis line orthogonal to the X axis is a Y axis, an axis line orthogonal to the X and Y axises is defined as a Z axis. When viewed along the Z axis, the ink tank is located in a region outside a movable region of the carriage along the Y axis, and is arranged so as to extend across a region outside the conveyance path along the X axis and a region that is overlapped with the conveyance path.
