1. A printing device comprising:
a printing unit that performs printing on a medium; and
a panel unit to which operation information for operating the printing unit is input, wherein
the printing unit includes a printing mechanism that executes a printing operation according to the operation information, a main circuit board including a processor that controls an operation of the panel unit and controls an operation of the printing mechanism based on the operation information, and a main housing that stores the main circuit board,
the panel unit includes a display panel, a capacitive touch sensor in which a position detection sensor and a cover glass are laminated, a panel circuit board electrically coupled to the capacitive touch sensor, a flexible wiring board that electrically couples the capacitive touch sensor and the panel circuit board to each other, a display circuit board including a display section that is electrically coupled to the panel circuit board and displays an operating state of the printing unit, a switch circuit board including a switch that is electrically coupled to the panel circuit board and activates the printing unit, and a panel housing that stores the capacitive touch sensor, the panel circuit board, the flexible wiring board, the display circuit board, and the switch circuit board,
the capacitive touch sensor includes a first side, a second side located facing the first side, a third side intersecting both the first side and the second side, and a fourth side located facing the third side,
the panel unit is rotatably attached to the printing unit so as to take a first attachment state and a second attachment state,
in the first attachment state, an angle formed by a horizontal direction and a normal direction of the capacitive touch sensor is larger than an angle formed by a vertical direction and the normal direction of the capacitive touch sensor,
in the second attachment state, the angle formed by the horizontal direction and the normal direction of the capacitive touch sensor is smaller than the angle formed by the vertical direction and the normal direction of the capacitive touch sensor,
when the panel unit is in the second attachment state, the capacitive touch sensor is disposed so that the first side is lower than the second side in a direction along the vertical direction,
the flexible wiring board is located between the display circuit board and the switch circuit board, and is curved to electrically couple the capacitive touch sensor and the panel circuit board to each other, and
the display circuit board is electrically coupled to the main circuit board via the panel circuit board.
