Abstract: An ultrasonic diagnostic apparatus according to an embodiment includes a body, a plurality of wheels, and control circuitry. The body sends and receives ultrasonic waves to generate an ultrasonic image. The plurality of wheels supports and moves the body. The assist wheel is electrically driven, and assists movement of the body. The control circuitry is configured to control switching between grounded and ungrounded of the assist wheel to a floor.

Abstract: In one embodiment, an ultrasonic diagnostic apparatus includes: a main body configured to generate an ultrasonic image; a body housing configured to house the main body; a display/operation panel configured to operate the main body and display the ultrasonic image; and a lifter on which the display/operation panel is placed, the lifter being attached to the body housing and configured to adjust height of the display/operation panel from a floor in each of an electric mode and a manual mode.

Abstract: According to one embodiment, the ultrasonic diagnostic apparatus includes a main body housing, an arm, a device, a table, and an avoiding mechanism. The arm is mounted to the main body housing so as to be capable of ascending and descending and pivotable about a predetermined axis. The device is supported by the arm so as to be capable of ascending and descending and pivotable according to the movement of the arm. The table has a surface which is positioned in a descending direction of the arm and the device, and an object is placed on the surface. The avoiding mechanism changes a relative position between the object and a support position of ascending and descending movement of the arm such that interference between the object and at least one of the arm and the device due to the descending movement of the arm is avoided.

Abstract: According to one embodiment, there is provided a trackball device provided for an operation panel of a predetermined computer, the device includes a first casing including a housing portion, a ball rotatably housed in the housing portion, a detector provided in the housing portion and configured to detect input information based on rotation of the ball, and a second casing including an opening portion and mounted on the first casing to restrain the ball in the housing portion while part of the ball is exposed from the opening portion, wherein the second casing further comprises a ring portion which is provided along the opening portion and exposed from the operation panel when the trackball device is provided on the operation panel, and is configured to be detachable from the first casing upon application of a dynamic action to the ring portion.
