Title: Moving-magnet built-in type galvanometer
Inventor: TANAKA KAZUO
IPC: G01R5/16
Filed: 1981-06-11
Abstract: PURPOSE:To prevent magnetic leakage to the outside, and also to make a galvanometer small-sized, by constituting a magnetic circuit of incorporating a permanent magnet in the inside of a rotor, and surrounding its circumference by a ferromagnetic substance. CONSTITUTION:A rotor consists of a flat permanent magnet 1 and a thin magnetic pole plate 2 which has been stuck to both its sides and has been screwed 2', and to the upper and lower parts of its center part, a rotary shaft 3 is installed. A stator 4 is placed at a position being extremely near the rotor, a static magnetic field generated by the permanent magnet 1 passes through a micro air-gap A, focusing the inside of the magnetic pole plate 2, passes through an air-gap B of one end and the other end in the stator 4, and is fed back. When a current is made to flow a control coil 4' wound around the stator 4, the static magnetic field and the dynamic magnetic field are multiplied in one side of the micro air-gap by the direction of the current, and both the magnetic fields are offset in the other side, therefore, the whole rotor is rotated by some angle. In this way, it is possible to not only get rid of mutual interference in case of using it as a multi-element, but also reduce the quantity of a magnet to be used.

Abstract: PURPOSE: To prevent respective band-shaped tickets from being illegally pulled out by surely cutting them at prescribed cutting positions by not transmitting motive force from a unidirectional clutch to a cam at the time of rotating a worm in a ticket sending-out direction but transmitting motive force when rotating the worm reversely. CONSTITUTION: A worm 10 is rotated backward by the inverse of a motor 9. As the result, a unidirectional clutch 30 is connected and the motive force of the worm 10 is transmitted to a cam 27. Thus, a cam follower 26 in contact with the cam 27 is driven, and a ticket cutting means 17 is moved. The ticket cutting means 17 moved upward is pushed into a cutting hole between respective tickets and helps the first ticket to be pulled out while preventing the second ticket from being pulled out. When a customer applies pulling force to the preceding first ticket, the first and second tickets are surely cut at the prescribed cutting position and only the first ticket is pulled out to the outside of a ticket dispensing port 6.
