Abstract: An operation indicating device for electromagnetic relay which comprises a working member interlockable with an armature of an electromagnetic relay and extending into a space above a yoke, and an indicating member coupled to the working member and having an axis rotatably supported in the space above the yoke, the indicating member having a recognizable indicating portion and being rotatable by the working member interlocking with the armature during the operation of the armature, the indicating portion of indicating member thus rotated arriving at a position corresponding to an indication window formed in a case cover.When the armature is activated, the working member, interlockable with armature, is activated and the indicating member coupled to the working member is rotated around a supporting shaft serving as the fulcrum.

Abstract: A printing apparatus for printing on both surfaces of a chip type article comprises first and second transfer paths for transferring the chip type article, an article feed device for feeding the article to the first transfer path, a printing device for printing on the article on the first transfer path and on another article on the second transfer path, an article removing device for removing the printed article on the second transfer path, and an article reversing device for reversing upsidedown the printed article on the first transfer path and for delivering to the second transfer path.

Abstract: In a terminal stage for connecting a wire terminal thereto for use in an electrical apparatus comprising an electrically conductive terminal plate having at least two threaded holes at least two terminal screws to be screwed in the respective threaded holes, and an electrically insulating supporting member having a first wall portion substantially perpendicular to the terminal plate and for supporting the terminal plate, there are provided at least two movable members each being movable in the direction substantially perpendicular to the terminal plate and each having a first portion extending in the direction substantially parallel to the terminal plate and supporting the terminal screws, a second portion formed integrally with the first portion substantially perpendicularly to the terminal plate, and a third portion integrally formed with the second portion and extending in the direction substantially parallel to the terminal plate, each of the movable members being adapted to be stably held in at least one

Abstract: Disclosed is a wire terminal connector for use in an electric device, comprising an electrically conductive terminal plate formed with at least one screw hole, and at least one terminal screw to be screwed into the screw hole, for fixing a wire terminal between the terminal plate and the terminal screw, in which the terminal connector further comprises: a movable electrically conductive member slidably supported perpendicularly to the terminal plate, the movable member including a first portion extending parallel with the terminal plate and supporting the terminal screw, and a second portion integrally formed with the first portion and extending perpendicularly to the first portion from one end of the first portion, the second portion being formed with a rectangular stopper portion for restricting a range of movement of the first portion; a compression spring with its one end supported by the second portion of the movable member; and a fixed spring-support portion for supporting the compression spring at the

Abstract: Disclosed is a digital switch which is manually rotated step by step and which comprises a casing, a wheel rotatably supported in the casing, device for manually rotating the wheel step by step, an electrical contact carried by the wheel, an electrical circuit board attached to the casing and provided with a plurality of electrical contacts which are successively touched by the electrical contact carried by the wheel when the wheel is rotated step by step, for producing an electrical signal in accordance with a stepping rotary position of the wheel, and a locking device for disabling the wheel rotating device.
