Cooktop with light emitting indicators

A heating cooker comprising:

• a box-like body having an opening at a top portion thereof;
• a top board closing the opening of the body;
• a heating unit inside the body that heats a heating target cooking vessel on the top board;
• and
• a light emitting indicator unit beside the heating unit, wherein
• the light emitting indicator unit includes:
• a case having an opening at an upper portion of the case facing the top board;
• a light emission source in the case;
• and
• an indicator sheet closing the opening of the case, wherein the indicator sheet includes:
• a light transmitting portion in proximity to the heating unit that passes light from the light emission source;
• and
• a light blocking portion having a main portion farther away from the heating unit than the light transmitting portion, the light blocking portion blocking the light of the light emission source, wherein
• the heating unit has a substantially circular outer circumferential portion,
• the case has a bottom surface in a substantially isosceles triangular shape, the case being disposed such that a base side of the substantially isosceles triangular shape faces the outer circumferential portion of the heating unit,
• the light emission source is disposed below the main portion of the light blocking portion, and is disposed near an apex away from the base side of the bottom surface of the case, and
• the base side of the bottom surface of the case is arc-shaped so as to conform to the outer circumferential portion of the heating unit, the case has a base wall that extends from the base side and the light transmitting portion is adjacent to the base wall.
