Description

  The present invention relates to a board case and a board mounting device for safely mounting a control board in a machine in a game machine such as a revolving game machine or a pachinko machine called a pachislot machine.

  In recent years, not only pachinko machines but also pachinko machines called pachislot machines have been actively used in conventional pachinko halls and pachislot halls. In these gaming machines, the winning probability is governed by the information in the ROM mounted on the control main board. For this reason, ensuring the security for the main board for control is a serious technical issue regardless of the model.

  In other words, in this type of gaming machine, the front of the device is opened and closed by the front door because the inside of the device needs to be frequently operated. Become. For this reason, in order to deal with the illegal actions such as remodeling of the main board for control (replacement of ROM, etc.) continuously, the mounting apparatus for the main board for control has various measures for preventing unauthorized modification. Ingenuity is taken.

  A typical board mounting apparatus that has been devised to prevent unauthorized modification includes, for example, a relatively thin board case that accommodates a main board, and a board case that is attached to a gaming machine as described in Patent Document 1. It consists of a case holder for mounting on the back plate surface of the cabinet.

  The board case has a rectangular shallow case body that holds the rectangular main board inside, and a rectangular cover for closing the front opening of the case body so that the inner main board can be seen from all directions. Both are formed of a transparent resin. The cover is fixed to the case body in a non-removable manner by a rotation engaging portion on the lower side and a plurality of caulking pins attached to both side portions on the upper side.

  The case holder is made of a rectangular resin plate corresponding to the substrate case, and is detachably attached to the surface of the back plate of the cabinet by a fixing pin, while the substrate case is detachably held on the front side. Specifically, the substrate case is detachably fixed to the case holder by a plurality of engaging protrusions provided on the lower side portion of the case holder and a plurality of caulking pins held at the center portion of the upper side of the substrate case.

  According to such a substrate mounting apparatus, the substrate case cannot be removed from the case holder and the substrate case cannot be opened unless the sealing portion by the caulking pin is broken with a tool such as a nipper. And when the caulking seal part is destroyed with a tool such as a nipper, the trace remains clearly, and the trace can be found immediately when the game machine is opened. In addition, the surface of the internal main substrate can be directly monitored through a transparent substrate case. As a result of these, fraudulent acts such as opening the substrate case to work on the main substrate or replacing the main substrate with the substrate case are effectively prevented.

  On the other hand, it is required to remove the substrate case from the case holder for inspection by the police or the like. For this reason, in the board mounting device, a plurality of caulking sealing portions of the board case and the case holder are provided, the board case is removed from the case holder by deliberately destroying the sealing portion at each inspection, and then another sealing is performed. The part is newly fixed with caulking pins. For this operation, a plurality of caulking pins are required, and the number of parts increases. Moreover, the effort which pushes a caulking pin into a sealing part for every removal work is calculated | required.

  Although some caulking pins are attached to the substrate case or case holder, the caulking pins need to be cut each time they are used, and the work is further complicated.

  As for the substrate case, when the internal substrate needs to be replaced, the caulking seal portion is destroyed, but the case where the seal portion is once destroyed cannot be reused. In order to enable reuse of the board case, it is considered to provide a plurality of caulking seals as in the case of the board mounting device, but in that case, it is the same as the case where a plurality of caulking seals are provided in the board mounting device. In addition, there are problems such as an increase in the number of parts and a complicated operation.

  An object of the present invention is to provide a substrate case that has a small number of parts that can be easily sealed and reopened and closed without using a separate member such as a caulking pin, and that can be easily sealed.

In such a case, the trace of cutting remains clear, so that if there is an illegal separation act, it can be immediately recognized.

  In the two inner first lock pieces 24A, the second lock piece 27A is not removed, so that when the first lock piece 24A is inserted into the insertion hole 34 of the corresponding fixing portion 33 of the case holder 30, the first lock piece 24A The lock piece 24 </ b> A is only pressed and elastically deformed downward by the tapered engagement claw 35 in the insertion hole 34, and the first lock piece 24 </ b> A is not fixed to the fixing portion 33. That is, if the substrate case 20 is intentionally separated from the case holder 30, the first lock piece 24 </ b> A comes out of the insertion hole 34 of the fixing portion 33 and can be reused.

  When it is necessary to intentionally remove the substrate case 20 from the case holder 30 due to inspection by the police, etc., the support portions 25A are separated in order to separate the outer two of the four first lock pieces 24A. Cut at the base. As a result, the first lock piece 24 </ b> A fixing the substrate case 20 to the case holder 30 is separated from the substrate case 20, so that the substrate case 20 can be easily detached from the case holder 30.

  When the substrate case 20 is re-fixed to the case holder 30 after the inspection, the second lock piece 24A to the second lock piece 24A on the inner two of the four first lock pieces 24A arranged at the center of the case body 20A. The lock piece 27A is removed. Then, the substrate case 20 can be sealed and fixed to the case holder 30 as in the first time. Accordingly, the substrate case 20 can be replaced once while using the same substrate case 20 and case holder 30.

  If the second lock pieces 27A are removed one by one from the four first lock pieces 24A arranged at the center of the case body 20A, the replacement can be performed three times. If the number of the first lock pieces 24A is increased, the number of replacements can be increased while using the two first lock pieces 24A for sealing and fixing.

  When it is necessary to open the substrate case 20, when the substrate case 20 is removed from the case holder 30, one of the two first lock pieces 24A on each side disposed on both sides of the case body 20A. At the two outer sides, the support portion 25A is cut at the base to separate the first lock piece 24A from the case body 20A.
