Reading device for image pattern information

摘要

A reading device for image pattern information is described, in which image pattern information such as those for handwritten characters or figures are read and stored in a memory device, after which the stored image pattern information is converted, according to requirement, into tactile information and is output. The device has equipment for adjusting the sequential speed of the image pattern information output as tactile information. By means of an adjustment of this type, the device is matched to the "reading" ability of the user. In addition, the device has equipment for comparing, with respect to the image pattern information for handwritten characters or figures, whether the information read at a previous point in time coincides with the information read at the present point in time, or not. By means of updating the various information read, the quantity of data stored can be reduced.
