  However, the band has a function as only a part of the sealing mechanism. Accordingly, an object of the present invention is to provide a gaming machine substrate case in which a band of a sealing mechanism has other functions.

  In order to solve the above-mentioned problems, the present invention is a board case for a gaming machine having a configuration as described in each claim. According to the first aspect of the present invention, the sealing mechanism has a plurality of band bodies and holding members that hold the band bodies that are inserted and are immovably held in the removal direction. . The belt body is structured to be inserted into the holding member and to connect both members in a rotatable manner, and is further inserted into the holding member to move both members relative to each other, and is provided between the two members. In addition, the two members are locked by the locking mechanism and the sealed state is maintained.

  Therefore, the belt body has two functions of a hinge function for connecting both members in a rotatable manner and a sealing function for bringing both members into a sealed state. Thus, the parts can be shared, and the board case can have a simple structure.

According to the second aspect of the present invention, the holding member is provided with the retaining claw for preventing the strip from coming off. The holding member is housed in a recess formed on the inner peripheral surface of the case body.

  According to the third aspect of the present invention, the locking mechanism has a locking claw portion provided on one member of both the case main body and the cover, and a locking receiving portion provided on the other member. ing. The cover is slid in a closed state with respect to the case body, so that the locking claw portion is locked to the locking receiving portion. Therefore, the locking mechanism is locked by sliding the cover with respect to the case main body, and thereby the substrate case can be sealed.

  An embodiment of the present invention will be described with reference to FIGS. The gaming machine 10 according to the present embodiment is a pachinko machine, and includes a rectangular frame-shaped outer frame 11 and a front frame 12 that is rotatably attached to the outer frame 11. A game board 13 or a ball tank is attached to the front frame 12. A board (control board 14 or the like), electrical wiring, or the like is attached to the back of the game board 13 as shown in FIG.

  The control board 14 is a board that controls the gaming machine 10 and is housed in the board case 1. The substrate case 1 includes a transparent resin case body 2 and a cover 3 as shown in FIGS. A binding band 4 constituting a sealing mechanism is attached between the case main body 2 and the cover 3. The case main body 2 and the cover 3 are formed with a plurality of insertion holes 2c and 3c through which the band 4a of the binding band 4 is inserted. The insertion hole 2 c passes through one end wall of the case body 2. The insertion hole 3c penetrates the cover 3 in the thickness direction.

  Between the case main body 2 and the cover 3, locking mechanisms 1 a and 1 b for locking the cover 3 by sliding the cover 3 relative to the case main body 2 are provided as shown in FIGS. The locking mechanism 1 a includes a pair of locking receiving portions 2 a formed on the inner side surface of the case body 2 and a pair of locking claws 3 a formed on the side portion of the cover 3. The locking mechanism 1b has a pair of locking claws 2b formed in a convex shape from one end surface of the case body 2, and a pair of locking receiving portions 3b formed in an opening window shape on one end surface of the cover 3. doing.

  As shown in FIGS. 2 and 3, the binding band 4 has a plurality (for example, four) of the belt bodies 4a and the holding members 4b. The band 4a has a first retaining claw 4c, a second retaining claw 4d, and a locking claw 4e, respectively. The first retaining claw 4c is formed on the surface of the band 4a in the vicinity of the holding member 4b. The second retaining claw 4d is formed on the back surface of the belt body 4a at the substantially longitudinal center position. A plurality of locking claws 4e are formed in a saw blade shape on the back surface of the band 4a.

  As shown in FIGS. 2 and 3, the holding member 4b is integrally formed at the end of the band 4a. The holding member 4b has a through hole 4b1 into which the band 4a is inserted and a retaining claw 4b2. The retaining pawl 4b2 prevents the strip body 4a from coming off the holding member 4b in cooperation with the locking pawl 4e of the strip body 4a inserted into the through hole 4b1. Therefore, the band 4a is held in a state of being prevented from being removed by the holding member 4b. The plurality of holding members 4b are connected in a juxtaposed manner.

  When assembling the binding band 4 to the case body 2 or the like, first, the band 4a is inserted through the insertion hole 2c as shown in FIGS. When the maximum amount of the band 4a is inserted into the insertion hole 2c, the first retaining claw 4c penetrates the insertion hole 2c. And the holding member 4b is installed in the recessed part 2d formed in the inner wall of the case main body 2 as shown in FIG.3 (B). Next, the band 4 a is bent, and the end 4 a 1 of the band 4 a is inserted into the insertion hole 3 c of the cover 3. Subsequently, the end portion 4 a 1 is inserted into the through hole 4 b 1 of the holding member 4 b and the insertion hole 2 c of the case body 2.

  As a result, the band 4a has a ring shape as shown in FIGS. 4 and 5, and connects the case body 2 and the cover 3 so as to be rotatable. Note that the amount of insertion of the band 4a into the holding member 4b at this time is an amount having a margin (hinge position). For this reason, the cover 3 is connected to the case body 2 in a slidable state.

  Further, as shown in FIG. 4, the end 4 a 1 of the band 4 a is inserted into the insertion hole 2 c of the case body 2 together with the base end. As a result, the band 4a can hardly move in the thickness direction in the insertion hole 2c, and the first retaining claw 4c cannot be removed from the insertion hole 2c. Therefore, the band 4a is attached to the case body 2 so as not to slide with respect to the insertion hole 2c. Further, the end 4a1 of the band 4a passes through the insertion hole 2c and protrudes to the outside so that it can be pulled.

  When the substrate case 1 is to be sealed, one of the end portions 4a1 of the band 4a is pulled as shown in FIG. Thereby, the band 4a is further inserted into the holding member 4b, and the ring diameter is reduced (sealing position). Thereby, the cover 3 slides with respect to the case main body 2 by the strip 4a. Then, the locking claws 2b and 3a are engaged with the locking receiving portions 2a and 3b, and the locking mechanisms 1a and 1b are in the locked state. And the cover 3 cannot be slid with respect to the case main body 2 by the belt | band | zone body 4a, and the board | substrate case 1 will be in a sealing state.

  When the substrate case 1 is changed from the sealed state to the opened state, the strip 4a is cut with a nipper or the like as shown in FIGS. 6 and 7A. Next, the cover 3 is slid with respect to the case main body 2 so that the locking mechanisms 1a and 1b are unlocked. As a result, the cover 3 can be rotated with respect to the case body 2, and the substrate case 1 is opened.

  Subsequently, when the substrate case 1 is to be sealed, the cover 3 is closed with respect to the case body 2. Then, as shown in FIG. 7B, one of the end portions 4a1 of the remaining band 4a is pulled. Thereby, the cover 3 is slid with respect to the case main body 2 by the belt | band | zone body 4a, and the latching mechanisms 1a and 1b will be in a latching state. Thus, the substrate case 1 is sealed. Subsequently, when the unsealed state is set, the band body 4 a is cut and the cover 3 is slid with respect to the case body 2. By the same method, the substrate case 1 can be brought into a sealed state and an opened state multiple times.

  The cutting position of the band 4a when opening is between the first retaining claw 4c and the second retaining claw 4d (see FIGS. 6 and 7). Therefore, when the end 4a1 of the band 4a is pulled, the second retaining claw 4d hits the holding member 4b. Therefore, the end 4a1 is prevented from being pulled out from the case body 2 side by the second retaining pawl 4d. Since the end 4a1 does not come out of the insertion hole 2c, the first retaining claw 4c can be prevented from coming out of the insertion hole 2c. Thus, even if the strip 4a is cut, it is prevented from being removed from the case body 2 by the first retaining claw 4c, the second retaining claw 4d, and the locking claw 4e. As a result, the trace that opened the substrate case 1 can be fastened by the cut band 4a.

  As described above, the sealing mechanism has a plurality of strips 4a and holding members 4b as shown in FIG. The band 4a is inserted into the holding member 4b and has a structure for connecting both the case main body 2 and the cover 3 so as to be rotatable, and is further inserted into the holding member 4b so that the two members are relatively It is also structured to hold the sealed state by moving both members by locking mechanisms 1a and 1b provided between the two members.

  Therefore, the belt body 4a has two functions, that is, a hinge function for rotatably connecting both members and a sealing function for sealing both members. Thus, the parts can be shared, and the substrate case 1 can have a simple structure.

  Moreover, as shown in FIG. 2, the belt | band | zone body 4a and the holding member 4b are provided integrally. The band 4a is inserted through the case main body 2 and the cover 3, and is inserted into the holding member 4b to be held in a ring shape. Therefore, the belt body 4a becomes a ring shape together with the holding member 4b. Therefore, a separate member or the like for connecting the band body 4a and the holding member 4b to the case body 2 or the like is not required. Thus, the belt body 4a and the holding member 4b can be easily attached to the case body 2 or the like.
