Abstract
On a circuit board 11 there are provided, other than a comparison circuit 12 mounting region, dictionary ROM mounting regions 18a and 18b and microprocessor mounting regions 19a and 19b, with an address bus 16 and a data bus 17 each connected to mounting regions 18a and 18b in parallel and to mounting regions 19a and 19b in parallel. Initially, a dictionary ROM 13a and microprocessor 15a are mounted on mounting regions 18a and 19a, respectively, and when the current version is to be upgraded a dictionary ROM 13b having dictionary data partially changed to do so is mounted in mounting region 18b and a microprocessor 15b having a program partially changed to do so is mounted in mounting region 19b. Consequently, there can be provided an image processing device that can ensure a high level of mounting-strength and can also readily allow for exchanging a component thereof and upgrading its version.
