A reflector array optical device includes two dihedral corner reflector array optical elements each having a substrate and a plurality of prism bodies arranged regularly on and each protruding from one main surface of the substrate. Each prism body includes at least two sides of orthogonal planes. The two optical elements are adhered so that top faces of the prism bodies are directly confronted respectively so as to make two coplanar planes in which the two orthogonal planes exist respectively.

A display device includes a dihedral corner reflector array optical element composed of a substrate and a plurality of dihedral corner reflectors arranged regularly on one main surface of the substrate, the dihedral corner reflectors including orthogonal mirror planes perpendicular to each other and being perpendicular to the main surface of the substrate; and an object existing by the one surface of the substrate, the optical element forming a real image of the object by the other main surface of the substrate. The optical element includes a plurality of protrudent bodies integrally formed of a transparent material of the substrate, each of the protrudent bodies including two sides of orthogonal mirror planes perpendicular to each other as the dihedral corner reflector perpendicular to the main surface of the substrate. The optical element is disposed so that the protrudent bodies face toward a space in which the object exists.

A display device is capable of freely setting a viewing location for a real image formed by an imaging optical system of real specular image. The display device includes: an object of view; the imaging optical system having a semitransparent substrate with a plane of symmetry to define an object side space in which the object exists and a viewer side space in which a viewer exists, where the imaging optical system forms a real image of the object of view in the viewer side space with light passing through the substrate; and at least one reflective mirror arranged in the object side space so as to reflect light beams from the object of view to guide the reflected light beams to the imaging optical system of real specular image.

A printing device includes a printing unit that prints a print-object image corresponding to print data on a recording medium. A placing unit places restriction information on the recording medium if the print data is attached with the first restriction condition. The restriction information is used for attaching a second restriction condition to scanned data that is generated by reading the print-object image printed on the recording medium. The second restriction condition is for placing restrictions on the usage of the scanned data.

A heat pump apparatus includes: a refrigerant circuit which includes a compressor, an utilization-side heat exchanger, a first expansion valve, and an outdoor heat exchanger; an injection pipe which includes a solenoid switching valve and a second expansion valve; and an objective supercooling degree table which stores objective supercooling degrees according to condensing pressure in the refrigerant circuit and rotation number of the compressor. In the heat pump apparatus, liquid refrigerant is injected to the compressor by way of the injection pipe. The heat pump apparatus switches between a first case where the liquid refrigerant is injected to the compressor and a second case where the liquid refrigerant is not injected, and a value of the objective supercooling degree is changed between the first case and the second case to control the first expansion valve based on the value of the objective supercooling degree.

A light source device can include a solid-state light source configured to emit blue light as excitation light and a phosphor section which is excited by the excitation light from the solid-state light source and which emits fluorescent light longer in wavelength than the light emitted from the solid-state light source. In the light source device, a wavelength selective member configured to transmit the excitation light from the solid-state light source and to reflect the fluorescent light from the phosphor section can be provided between the phosphor section and the solid-state light source. The size of the wavelength selective member can be less than the size of the phosphor section which can be greater than the size of the excitation light spot irradiated with the solid-state light source.
