Title:
BAR CODE READER FOR CAMERA, BROWNIE FILM AND BAR CODE INDENTIFICATION SYSTEM
Document Type and Number:
Japanese Patent JP3644568
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To accurately and efficiently set a reference length being the criterion for thick width or thin width of a bar code recorded on the joining tape of a Blownie film.
SOLUTION: The bar code consisting of 13 bits of bit numbers (1)-(13) is recorded on the joining tape 11. The kind of film including a film size (length) is assigned to the first three bits. Code data of the first three bits is constituted of a combination of one thick width and two thin widths and the data length of three buts is constant. The bar code is read by a photosensor, to obtain width data at each bit position and then, the reference length for deciding whether each width data corresponds to the thick or thin width is set on the basis of the data length of the first three bits. The width data of the first three bits is used for both of the identification of the kind of film and the setting of the reference length.
