Tape measure having light emitting device

A tape measure having a light emitting device, which comprises a housing, a reel received in the housing, and a blade wound on the reel to be extended or retracted through an inlet of the housing, the tape measure comprising:

• a first case;
• a second case coupled with the first case to form the housing;
• a light emitting portion positioned in front of the center of the reel around the inlet of the housing;
• and
• a light emitting circuit portion positioned in the rear side of the center of the reel by facing the light emitting portion,
• wherein the light emitting circuit portion includes a circuit board disposed on a rear lower side of the housing, and the first case and the second case provide circuit receiving spaces for receiving the circuit board, respectively,
• wherein a first elastic introduction hole connecting the circuit receiving space and the outside is formed in at least one of the first case and the second case, and
• wherein a part of at least one of a first elastic layer formed integrally on the outer surface of the first case and a second elastic layer formed integrally on the outer surface of the second case is extended and formed to pass through the first elastic introduction hole to provide a first impact absorbing portion supporting an upper surface, a lower surface, or a rear surface of the circuit board.
