First Claim
Patent Images
1. A device for storing a vehicle identification code that includes a character string of a plurality of digits, the device comprising:
- a writing request detection section that detects a request for writing the vehicle identification code;
an encoding section that compresses and encodes the vehicle identification code that corresponds to the detected writing request, thereby generating a storage code; and
a storage code storing section that stores the storage code,wherein each character in the vehicle identification code is inputted as proper data to the encoding section, the proper data contains code data representing the character and overhead bit data appended to the code data, wherein the encoding section deletes at least part of the overhead bit data, thereby compressing the vehicle identification code into the storage code.

Abstract
A device stores a vehicle identification code that includes a character string of a plurality of digits. The device includes a writing request detection section that detects a request for writing the vehicle identification code. An encoding section compresses and encodes the vehicle identification code that corresponds to the detected writing request to generate a storage code. A storage code storing section stores the storage code. Therefore, the device efficiently stores the vehicle identification codes in a nonvolatile memory.

4. A device for storing a vehicle identification code that includes a character string of a plurality of digits, the device comprising:
-
a writing request detection section that detects a request for writing the vehicle identification code; an encoding section that compresses and encodes the vehicle identification code that corresponds to the detected writing request, thereby generating a storage code; and a storage code storing section that stores the storage code, wherein each character in the vehicle identification code is expressed by a binary code that corresponds to a hexadecimal number equal to or greater than a predetermined value, wherein the encoding section subtracts a hexadecimal number equal to or less than the predetermined value from a hexadecimal number corresponding to the inputted binary code, and wherein the encoding section expresses the resultant of the subtraction with a binary code the number of bits of which is less than that of the inputted binary code, thereby compressing the vehicle identification code into the storage code. - View Dependent Claims (5)
