Electronic equipment and television game machine having heat radiation structure

An electronic equipment to be connected to a display device of a gaming machine and removably attached with an optical information recording medium optically recording data for image display, comprising:

• an optical information reading unit for reading out data for image display recorded on said optical information recording medium;
• at least one semiconductor device for processing data for image display read out by said optical information reading unit to generate image data, wherein heat generation occurs during processing operation thereof;
• a printed board on which said semiconductor device is mounted;
• a housing having an attaching portion formed on a top surface of the housing to removably attach said optical information recording medium on the housing, the housing having a space to stack and accommodate in a height direction at least said optical information reading unit and said printed board, accommodating said optical information reading unit in a position related to said attaching portion, and accommodating said printed board in a position below said optical information reading unit with a predetermined spacing,
• the housing including an air exit in a first side surface of the housing and an air intake in a second side surface of the housing at a position distant from and corresponding to said air exit so as to have an air flow passage for flowing air on a line linearly connecting between said air exit and said air intake;
• a heat-radiating member having a first open end portion and a second open end portion, the heat-radiating member arranged on said air flow passage in a manner so that the first open end portion is close to the air exit and the second open end portion is close to the air intakes the heat-radiating member being electrically insulated from said semiconductor device and capable of transferring heat generated from said semiconductor device, and the heat-radiating member having a plurality of heat-radiating fins and linear grooves formed along said air flow passage, said fins and grooves extending between the first and second open end portions of the heat-radiating member;
• wherein a width of the air exit is smaller than a width in a depth direction of the first side surface of the housing, a width of the air intake is smaller than a width in a depth direction of the second side surface of the housing;
• and
• a heat-radiating fan provided between at least one of said air intake and said air exit and a corresponding end of said heat-radiating member to cause air taken through said air intake to flow along the grooves and heat generated from said semiconductor device to be forcibly released through said air exit.

An electronic game equipment to be used in conjunction with a display device, comprising:

• an optical information reading unit for reading out data for image display recorded on an information recording medium;
• at least one semiconductor device for processing data for image display read out by said optical information reading unit, so as to generate image data, and wherein heat generation occurs during processing operation of the semiconductor device;
• a circuit board supporting said semiconductor device;
• a housing having a space to stack and accommodate at least said optical information reading unit and said circuit board, with the circuit board being located at an elevation below said optical information reading unit;
• the housing including an air exit in a first side of the housing and an air intake in a second side of the housing, and a linear air flow path being defined in a linear manner between the air intake and the air exit;
• a heat-radiating member having a plurality of parallel elongated fins and grooves extending in a manner so as to be aligned with each of the air intake and the air exit, the heat-radiating member being located in the linear air flow path directly between the air intake and the air exit and below the optical information reading unit, and the heat-radiating member being electrically insulated from said semiconductor device and capable of transferring heat generated from said semiconductor device;
• and
• a fan provided between at least one of said air intake and said air exit and a corresponding end of said heat-radiating member to cause air taken through said air intake to flow along the grooves and heat generated from said semiconductor device to be forcibly released through said air exit.
