<p>PURPOSE:To write and record arbitrarily information and call and display it as required, by providing a conversion unit which converts write information to an electric energy. CONSTITUTION:In case that information is written by a light, a pressure, etc., from the external, write signals are converted to electric signals by conversion unit 1 which converts write signals to an electric energy. These electric signals are stored in memory circuit 5, and written information is displayed on display unit 2 through driving circuit 3. Written signals are displayed in real-time, and written signals are recorded in a part of memory circuit 5 by operating control circuit 6 by the operation key of operation part 7 as required. Then, logical operation circuit 4 is provided and is provided with a calculation function to perform calculation and record the result. Operation part 7 consists of arithmetic operation part 9 for calculation function and write part 10.</p> |
