Abstract: An information processing device for processing ultrasonic wave information obtained from an ultrasonic wave sensor including a plurality of ultrasonic wave elements. The information processing device includes an obtainer configured to obtain the ultrasonic wave information from the ultrasonic wave sensor provided on a body surface of a subject, a recognizer configured to recognize a first blood vessel of the subject and a second blood vessel, based on the ultrasonic wave information, the second blood vessel being different from the first blood vessel, and a controller configured to cause a display to display comparison information in which first blood vessel information relating to the first blood vessel and second blood vessel information relating to the second blood vessel are compared with each other.

Abstract: A pictorial symbol switch which is effective to minimize a panel and to prevent an operation in error thereof. The pictorial symbol switch comprises first and second switch units having first and second pictorial symbols indicated on surfaces thereof, respectively, and visually representing first and second events, respectively, which relate to each other and are each to take place when the first or second switch unit is depressed. Thus, an operating section and a display section are provided in an integral relationship with each other for each of the switch units of the pictorial symbol switch.

Abstract: A photosensitive sheet (11) having photohardenable microcapsules is unrolled to be intermittently fed onto the exposure stage (300), and color separated images are projected onto a common area of the photosensitive sheet. A receiver paper (12) having a color coupler layer is overlaid on the photosensitive sheet, and pressed with a press roller mechanism (700), whereby a color image appears on the receiver paper. The receiver paper is separated from the photosensitive sheet, and thermally treated with a heater (820).
