Abstract:
1. A recording system which includes an image supply device and an image recording device, both complying with a predetermined standard, wherein the image recording device records an image on a recording medium on the basis of image data supplied from the image supply device, wherein a command code to be exchanged between the image supply device and the image recording device has a predetermined number of digits, wherein upper digits of the command code construct a common code and lower digits of the command code construct a unique code, wherein an interpretation of the common code is the same by all image recording devices complying with the predetermined standard, and wherein an interpretation of the unique code changes according to each image recording device even if all image recording devices comply with the predetermined standard, wherein in a case that the command code designates a layout of images to be recorded on the recording medium by the image recording device, the common code can be used to designate an index recording function, and if the common code designates the index recording function, then the unique code is used to designate a determination method of a number of index images to be recorded on a single recording medium in the index recording function, and wherein when the common code designates the index recording function, the image recording device sets the index recording function, and the image recording device interprets the unique code to determine a number of index images to be recorded on one recording medium based on the determination method, and determines the maximum number of index images that can be recorded on the one recording medium and a total number of index images designated by the command code, so that the image recording device records the index images designated by the command code on one recording medium or a plurality of recording media.
