Printing device

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 relay board that relays a signal propagated between the main circuit board and the panel unit,
• the panel unit includes a display panel, a touch sensor in which a position detection sensor and a cover glass are laminated, and a panel circuit board electrically coupled to the touch sensor,
• the 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 touch sensor is larger than an angle formed by a vertical direction and the normal direction of the touch sensor,
• in the second attachment state, the angle formed by the horizontal direction and the normal direction of the touch sensor is smaller than the angle formed by the vertical direction and the normal direction of the touch sensor,
• when the panel unit is in the second attachment state, the touch sensor is disposed such that the first side is lower than the second side in a direction along the vertical direction,
• the relay board includes a wireless communication device attachment portion to which a wireless communication device configured to receive a wireless signal from an outside by wireless communication is attached, and
• a shortest distance between the panel unit and the relay board is smaller than a shortest distance between the panel unit and the main circuit board.
