| 摘要 | PURPOSE: To attain to enhance accuracy by the wt. reduction and the miniaturization of a light emitting element display for sonar or radar, by supplying receiving information to a displaying light emitting element line by optically coupling a fixed part corresponding to the axis of a rotary part. CONSTITUTION: A display part provided with LED lines 1, 2 and a base plate 3 or a slit plate equipped with an angle detecting slit or a synchronism detecting slit is integrally revolved by a rotary cylinder 6 and a motor 19 and receiving informations such as an azimuth or a distance are displayed through LED lines 1, 2. A fixed part corresponding to the axis of this rotary part is optically coupled by light receiving elements and light emitting elements B and A, D and C while transmission synchronous information and reflected wave receiving information are respectively supplied through the elements B, D to control of the lighting of the LED lines 1, 2 corresponding to a distance. Therefore, a mechanical contact part becomes unnecessary in a signal system and the constitution of a light emitting element display for sonar or radar is reduced in the wt. thereof and miniaturized to enable the achievement of accuracy enhancement.
