An information transmitter apparatus for use in an information transmission system is provided, where the information transmission system includes the information transmitter apparatus and an information receiver apparatus. The information transmitter apparatus transmits a surface-shaped visible light signal using a light source, where the visible light signal is modulated according to a modulated signal modulated using a plurality of respective-order carriers different from each other, and the respective-order carriers has a fundamental frequency and multiple frequencies of a frame output signal of a video camera of rolling shutter system provided in an information receiver apparatus. The information receiver apparatus receives the visible light signal using the video camera. The information transmitter apparatus includes a modulator that quadrature-amplitude-modulates the respective-order carriers in accordance with input digital data signal, and inverse-Fourier-transforms modulated carriers to generate the modulated signal.

A transmitter sets a time length, determines a time point at which phases of frequency signals coincide within a range of the time length, defines a determined time point as a time reference point, aligns the phases of the frequency signals based on the time reference point, combines phase-aligned frequency, and transmits combined frequency signals to a receiver by the time length as the communication signals. The receiver receives the communication signals, extracts the phases of the frequency signals, obtains a time point at which the phases coincide, and determines an obtained time point as the time reference point.

An figure data input device is provided, by which prompt and accurate simulation learning is realized by automatically reading out type identifying data and location data of a figure piece when the piece figure is placed on a mounting board. The educational figure data input device includes a figure piece composed of a figure portion replicating the outward appearance of an object and a storage unit for storing the type of the figure portion, which are combined into one body; a mounting board provided with a plurality of sectional mounting planes in such a manner that one figure piece is placed on only one of the plurality of sectional mounting planes; and a reading device, incorporated in the mounting board, for reading out type identifying data stored in the storage unit of the figure piece placed on the mounting board.
