Abstract:
An intermediate unit includes a transportation path provided with a drying unit that accelerates the drying of the medium. The transportation path includes an inlet path, an outlet path, a first branch path, a second branch path, a first junction path, a second junction path, a switch-back type inversion path with a first inversion path and a second inversion path. The first branch path and the second branch path which branch off at a branch point from the inlet path. The first junction path and the second junction path and the outlet path join each other at a junction point. The first branch path and the first junction path and the first inversion path join each other at a first connection point. The second branch path and the second junction path and the second inversion path join each other at a second connection point.

Abstract:
An ultrasonic element includes a substrate in which an opening is formed, a vibrating plate provided at the substrate, the vibrating plate including a first surface in contact with the substrate, the vibrating plate blocking the opening, a piezoelectric element provided at a second surface on an opposite side from the first surface of the vibrating plate, a protective substrate facing the second surface and protecting the piezoelectric element, and a suppressing unit provided between the protective substrate and the vibrating plate, the suppressing unit being configured to suppress a vibration of the vibrating plate, in which in the piezoelectric element, a first electrode, a piezoelectric layer, and a second electrode are stacked in this order from the second surface, and an active part is a part of the vibrating plate where the first electrode, the piezoelectric layer, and the second electrode overlap, the suppressing unit is provided around the active part, and a slit is formed in the suppressing unit, in plan view from a stacking direction.
