Abstract: An image processing portion (1) performs binarization, segmentation, and feature extraction of a received image using a RAM (2), compares the extracted feature with specific pattern data stored in a dictionary data memory (3), performs recognition processing, and provides recognition results to a CPU (4). The dictionary data memory is a volatile memory, in which specific pattern data held by the CPU is written by the CPU when power is turned on. Since the data stored in the volatile memory is erased when power is turned off, the dictionary data memory can be removed and the contents are analyzed when the power is turned off without causing any trouble.

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.

Abstract: The purpose of the invention according to this application is to offer a load displacement preventing device and a method of prevention of load displacement using the said device in such a manner that the attachment and detachment thereof can be accomplished by a single person without requiring tedious work and without the risk of displacement or disturbance of the stacked load or of damage caused to said load during the attachment thereof.
