发明名称 PATTERN INFORMATION READING APPARATUS
摘要 The invention relates to a pattern information reading apparatus in which pattern information such as characters or figures is read and stored in a memory and, thereafter, the stored pattern information is converted into tactile information and output as necessary. The apparatus has means for adjusting a moving speed of the pattern information which is output as tactile information. The apparatus is fitted to the reading capability of the user by such an adjustment. The apparatus also has means for comparing to see if the information which has been read at a preceding time point coincides with the information which was read at the present time point or not with respect to the pattern information such as characters or figures. By updating the different read information, the amount of storage data can be reduced.
