Abstract: An information display device includes: an image display unit that displays an image according to an orientation of a display screen; a terminal posture detection unit that detects a posture of the device using an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor; and a display direction determination unit that determines whether or not the posture of the device changes, and determines the orientation of the display screen. In the case where the display screen is substantially horizontal and the posture of the device changes, the orientation of the display screen is determined so that, when the device moves by a predetermined angle or more with respect to the orientation (reference orientation) of the display screen before the determination of the posture change, a side of the device at the predetermined angle or more from the reference orientation corresponds to the top of the display screen.

Abstract: A syringe drive device 15 according to the present invention includes: an outer tube fixing portion 31 that detachably fixes an outer tube 22 of a syringe 16; a plunger holder 21 that holds a plunger 17 of the syringe 16; and a drive portion that moves the plunger holder 21 along an axis of the syringe.

Abstract: A vehicle includes a contact-position-dependent type operational intention determining unit that detects a change in posture of a rider using posture sensors for a backrest disposed in areas of a backrest with which left and right shoulder blades of the rider come into contact, and thereby determines whether there is an operational intention of the rider; and a left-right amount-of-change comparison type turn intention determining unit that determines, only when it is determined that there is an operational intention, whether there is a left or right turn intention of the rider from a difference between sensor output values located left-right symmetrically.
