A message providing apparatus according to one embodiment is apparently a small-sized (for sample, screen size of about 3.5 inches) flat display (for example, LCD), wherein a speaker is provided at a cabinet, and a memory card that is a message data storage medium is inserted into the cabinet. Advertisement display data is stored to be classified into a moving image layer indicating a landscape, a still image layer indicating a commodity, a graphic (POP) layer indicating a price, a character layer indicating a catch phrase, and a sound layer which are displayed to be superimposed as required. BGM music data is also stored as the sound layer, and is reproduced in synchronism with a display. Advertisement characters are printed at the cabinet. When power is supplied, the apparatus automatically starts data reproduction of the memory card (by using a power on play function), and when all the data has been reproduced, the apparatus automatically restarts reproduction (by using an auto replay function). The message providing apparatus can be disposed on a commodity display shelf in place of a conventional advertisement providing apparatus so that image or sound information such as television commercial message popular among consumers can be distributed near commodities.

Message providing apparatus

A method of preventing color accurate reproduction of a colored pattern with color photocopiers or color photography using photosensitive materials having spectral sensitivity in the wavelength ranges consisting of the human visible range and the adjacent wavelength ranges thereto, comprising, forming at least portion of the colored pattern with a color material having a spectral reflection factor curve with high spectral reflection in at least one of the areas of wavelength below 450 nm and above 650 nm so that a reproduction of the colored pattern is in a color not perceivable by a direct human viewer of the colored pattern. The color material also has at least one high spectral reflection peak or area within the human visible wavelength range so that the perceived color of the colored pattern is different from a reproduced color using color photocopiers or photography.

Method of preventing color accurate reproductions using color

A document with a color pattern which is resistant to forgery by photo reproducing process, at least a portion of the color pattern comprising, a coloring material having a spectral reflection factor curve which is relatively high at a wavelength in at least one of the areas below 450 nm and about 650 nm, with respect to the rest of the curve. A method is also disclosed for avoiding reproduction of a document having colored areas using photo reproducing processes.
