Abstract: A printing apparatus includes: a roll sheet container that contains a roll sheet around which a recording sheet is wound; a first sheet guide that makes contact with a first surface of the recording sheet; a second sheet guide that makes contact with a second surface of the recording sheet; and a transport roller that transports the recording sheet. The first and second sheet guides are disposed so as to face each other to form a sheet route along which the recording sheet is to pass. The transport roller transports the recording sheet that passed along the sheet route. The second sheet guide includes: a projection that protrudes toward the roll sheet container; and a pushing section that extends from the projection along an outer circumference of the roll sheet and in a direction away from the first sheet guide.

Abstract: In a first operation, in a tournament circuit, any one row of data lines is selected according to a selection signal, and a voltage of the selected data line is output to a test output terminal via an amplifier. In a second operation, a selection circuit in a first layer in the tournament circuit is in an off state between all the data lines and an input end of a selection circuit in a second layer.

Abstract: A recording device includes a sandwiching member coming into contact with a first guide shaft at a guide shaft-side contact surface and disposed between a carriage and the first guide shaft in a second direction and a cam member coming into contact with a first curved surface of the sandwiching member and configured to rotate about a first direction as a rotation axis relative to the carriage in a state of being engaged with the carriage. The cam member presses the first curved surface with the second curved surface slidably fitted to the first curved surface in the second direction and changes a position of the carriage relative to the sandwiching member in the second direction as a distance in the second direction of a position at which the second curved surface presses the first curved surface relative to the rotation axis changes along with rotation of the cam member.

Abstract: An electro-optical device may include a first substrate, a second substrate, a seal member extending in a first direction and disposed between the first and second substrates in a seal region defined around a pixel area, a first conductive layer disposed between the first substrate and the seal member and extending in a second direction intersecting with the first direction, a second conductive layer disposed between the first substrate and the first conductive layer and extending in the second direction, a third layer disposed in the pixel area and formed of the first conductive layer, and a fourth layer disposed in the pixel area and formed of the second conductive layer. In plan view, the first conductive layer overlaps the second conductive layer in the seal region. In a cross-sectional view the first direction, the second conductive layer is larger in an outer shape than the first conductive layer.
