PROBLEM TO BE SOLVED: To permit a control substrate storing box to be opening-impossible without leaving traces and to prevent an illegal action against a PACHINKO (Japanese pinball game) machine by hiding an assembling means for integrally assembling a case body, a control substrate to be housed in the case body and a cover body to cover the case body by means of a hiding means. SOLUTION: In order to assemble the control substrate housing box, at first, a main substrate 91 is held between the ribs 212a and 212b, a pawl 214 of a case member 204, screws 220a and 220b are put through screw through-holes 218a and 218b and screwed onto bosses 216a and 216b and the main substrate 91 is housed inside the case member 204 and fixed. Then, the screws 222a and 222b are put through the screw put-through holes 226a and 226b and screwed onto the bosses 224a and 224b, and an insertion pin fixing stand 210 is attached to a fixed stand attaching part 206. A cover member 202 is covered over the main substrate 91 from its upper part, the head part of a heated insertion pin 236 is driven and its groove part is locked to lock holes 228a-228d. Thus, the screws are hidden by screw cover pieces 232 and 234.
