Abstract: An electromagnetic relay includes a fixed terminal, a movable contact piece, a first contact, and a second contact. The fixed terminal includes a first surface. The movable contact piece includes a second surface disposed to face the first surface. The first contact is embedded in one of the fixed terminal or the movable contact piece to be flush with one of the first surface or the second surface. The second contact is disposed on the other of the fixed terminal or the movable contact piece to face the first contact. The second contact protrudes from the other of the first surface or the second surface toward the first contact and include a contact surface smaller than the first contact when viewed from a direction facing the first contact.

Abstract: A relay includes a movable contact piece having a movable contact, a fixed contact, a drive device configured to move the movable contact piece, a magnet to apply a Lorentz force to an arc in a first extension direction, a fixed terminal having an intermediate portion to apply a Lorentz force to the arc in a second extension direction, and a wall portion. The wall portion includes first and second wall surfaces. The first wall surface is disposed to face an arc-extinguishing space, and is disposed opposite to the movable contact and the fixed contact in the first extension direction. The second wall surface is disposed to face the arc-extinguishing space and is disposed downstream in the second extension direction with respect to the first wall surface. A distance from the movable contact piece to the second wall surface differs from a distance to the first wall surface.

Abstract: A relay includes a fixed contact, a movable contact piece including a movable contact, a movable portion, a coil, a return spring, and a contact spring. The movable portion includes a drive shaft and a movable iron core. The drive shaft is fixed to the movable contact piece in a contact case and extends from an inside of the contact case to an outside of the contact case. The movable iron core is connected to the drive shaft outside the contact case. The return spring urges the movable portion in an open direction in which the movable contact is separated from the fixed contact. The contact spring urges the drive shaft in a contact direction in which the movable contact contacts the fixed contact. The contact spring is arranged outside the contact case.

Abstract: A printing apparatus includes a first screen facing in a first direction, a second screen facing in a second direction different from the first direction, and a processor that controls display of the first screen and display of the second screen. The processor performs control for displaying a first image on the first screen and, simultaneously, displaying a second image on the second screen. A first action of a user on which guidance is provided by the first image and a second action of a user on which guidance is provided by the second image are actions configured to be performed simultaneously.
