Abstract

PURPOSE: To realize a highly precise information reproducing device by providing an arithmetic circuit, etc., to convert discordance due to inclination between a line sensor and bit string information into regular data on the basis of definite pattern information recorded in a recording medium.
CONSTITUTION: A control processing circuit 1 consists of a CPU 100, a ROM 101, and a RAM 102. In a sensor signal processing circuit 2, the drive and the read-out of the sensor 7 are executed by a circuit 201, and the correction processing and the digitization of the read signal are executed by the circuit 202. The arithmetic circuit 3 converts the discordance between the sensor 7 and a bit information array into a regular array by using a digital signal processor DSP 301 and the RAM 302. A refresh circuit 4 is divided into parts for picture use and for sound use, and they consist of control circuits 401, 403 and the RAMs 402, 404 respectively, and the input to the RAMs 402, 404 and the refreshing of a picture and a sound signals are executed by these circuits. A display device 81 is a display such as a CRT, etc. The sound signal is converted into an analog signal by a D/A converter 405, and is reproduced from a speaker 82.
