Abstract: In order to provide an induction heating cooking device in which a supporting configuration of a heating coil unit is simple and can be easily assembled, and which can accurately and constantly maintain a distance between a top plate and heating coils, opposite side surfaces of a framework laid out below the top plate are configured to have first vertical parts, first horizontal parts, and second vertical parts. A heating coil supporting member that supports the heating coils is disposed to be bridged between the first horizontal parts of the opposite side surfaces of the framework, and the heating coil unit having the heating coil is configured to be securely supported by the first horizontal parts.

Abstract: An infrared sensor for detecting infrared rays of light and a light emitting element are disposed below a light transmittable top plate, which has a hearing area for heating an article to be heated placed thereon, in juxtaposed fashion relative to each other, so that infrared rays of light radiated from the article to be heated may be guided towards the infrared sensor. A light guide portion is provided for guiding rays of flight, emitted from the light emitting element, towards a heating area of the top plate, and the rays of light emitted from the light emitting element and guided by the light guide portion are projected onto the top plate through an upper opening of the light guide portion so that such rays of light can be noticed with eyes within the heating area.

Abstract: A heating cooker includes a top plate, a front frame for covering a front edge of the top plate, and opposite side frames for covering respective side edges of the top plate. A front end (edge) of each of the side frames is inserted into and covered by a side portion of the front frame. The side frame has a ridge formed on an outer surface thereof at a location a predetermined distance spaced apart from a front edge thereof such that the ridge is positioned along a rear end (edge) of the front frame.

Abstract: A press-in portion (11) of a press-fit terminal (10) is held by jigs (21) from opposite sides along a direction substantially normal to the longitudinal direction of the press-in portion (11), and a load (F) acting on the movable jig (21b) and a displacement amount of the movable jig (21b) are measured at this time and the measurement data are written in a data table for terminal. Then, a load (Fp) at a point of coincidence of the data table for circuit board written with the load (F) necessary to widen a hole (H) of a circuit board (K) and a hole diameter of the widened hole (H) and a data table for terminal obtained by the measurement is obtained. Whether the load (Fp) at the point of coincidence lies within a judgment reference range is judged and this judgment result is displayed on a display (44).
