PROBLEM TO BE SOLVED: To provide a call display device in a game machine equipped with a plate display device which makes a luminous display of a plate itself and enables a parlor clerk to easily attach or replace the plate in accordance with the condition of the game machine. SOLUTION: The call display device 9 is integrally composed of a display unit 20 and a lamp unit 32. The display unit 20 is formed by inserting a display plate 25 into a body portion 40 incorporating an LED and making the insertion end of the display plate 25 front on the LED. The display plate 25 is formed of an acrylic plate or the like and printed with a prescribed letter or a design by a diffuse reflectance ink. When a signal from a pachinko machine makes the LED luminous, the light hits the printed portion of the display plate 25 and is diffusedly reflected, making the letters or designs printed on the display plate 25 luminous.
