Abstract: According to one embodiment, an indirect transfer medium includes: a base material; and an image receiving layer on which an image is capable of being formed by ink-jet printing. The image receiving layer includes a vinyl acetate maleate copolymer as thermo-adhesive material. The image receiving layer is laminated on the base material.

Abstract: A printed matter includes: a first sub image embedded in the main image which has the same color as a color of the main image in a human visual sense, and is printed with an ink to absorb light of an infrared wavelength band by a first absorption coefficient; and a second sub image embedded in the main image which has the same color as the color of the main image in a human visual sense, and is printed with an ink to absorb the light of the infrared wavelength band by a second absorption coefficient.

Abstract: According to one embodiment, a limpness detecting device includes a transmitting unit to irradiate an acoustic wave towards a conveyed sheet to excite a Lamb wave, a first receiving unit to detect a leaky wave of the Lamb wave emitted from a front surface of the sheet, a second receiving unit to detect a leaky wave of the Lamb wave emitted from a back surface of the sheet, a comparison data calculating unit to calculate comparison data based on the signal detected by the first receiving unit and the signal detected by the second receiving unit, and an intactness judgment unit to compare the comparison data calculated by the comparison data calculating unit with a preset standard value and judge whether the sheet is an intact bill or not, based on a result of the comparison.

Abstract: According to one embodiment, an ultrasonic line sensor includes a plurality of ultrasonic sensors each comprising a circular vibrating surface and generating an electrical signal in accordance with an ultrasonic wave that enters the vibrating surface; and at least one sound absorbing member that is provided between the vibrating surfaces of the ultrasonic sensors and a detection target, and that absorbs an ultrasonic wave, the sound absorbing member being arranged in a position where the sound absorbing member overlaps both edge portions of the vibrating surfaces in a scanning direction that is perpendicular to a conveying direction of the detection target such that effective regions, which are regions in the vibrating surfaces not overlapped by the sound absorbing member, each have two sides parallel to the conveying direction of the detection target.
