Abstract

PURPOSE:To readily measure the distance along a meandering path between two points in response to every kind of reduced scales on maps, by rotating and moving a rotary wheel between two arbitrary points, and reading the number of rotation and graduation of said rotary wheel. CONSTITUTION:The graduation 2 is provided along the circumference of the side face of the rotary wheel 1. A spring piece 1 is repelled every rotation of the rotary wheel 1, and the number of rotation is perceived by the repelling sound of the spring piece 3, or the number is displayed at every rotation of the rotary wheel 1. A number of rotation display device is constituted in this way. The diameter of the rotary wheel 1 is 3.18cm so that the circumference thereof is exactly 10cm. The rotary wheel 1 is rotated and moved between the two arbitrarily separated points on the map, and the distance is measured by the number of rotations and graduation of the rotary wheel 1.
