PROBLEM TO BE SOLVED: To easily identify specified parts of a pachinko machine. SOLUTION: Characters 22 and 23 showing each name are integrally formed in the positions, visually observable in the assembled state, of the rear faces of a ball tank 12 and a rear cover 18 made of resin. Characters 24 showing a name are integrally formed on the rear face of a body case 15a made of resin. Characters 25-29 showing each name are printed on the rear faces of printed circuit boards such as a delivery control board 16, a main control board 17, an external information terminal board 19, a distribution board 20 and a power board 21 simultaneously with the formation of wiring patterns. Parts can thereby be easily identified by looking at the display of the names put on the respective parts without looking at a design drawing or the like. In the case of a pachinko hall clerk requesting a manufacturer or the like to repair defective parts, such an error as to give the names of wrong parts can thereby be eliminated.
