Description

  The present invention relates to a gaming machine.

  For example, a slot machine equipped with a stop button, a so-called pachislot machine, has a variable display device configured by arranging a plurality of mechanical rotating reels that display a plurality of symbols in the front display window, or a symbol on the reel on the screen. It has an electrical fluctuation display device for displaying. In response to the player's start operation, the control means drives the variable display device to rotate the reels to display the symbols in a variable manner. After a certain period of time, either automatically or by the player's stop operation, Stop rotation sequentially. At this time, when the symbols of the reels appearing in the display window are in a specific combination (winning symbol), the player is given a profit by paying out game media such as coins and medals.

  Currently, the mainstream model has a plurality of types of winning modes. In particular, when a winning combination of a predetermined combination is established, the game state is better in condition than the normal state for a predetermined period of time, instead of completing one coin payout. As such a combination, a combination that can play a game that gives a relatively large profit to the player a predetermined number of times (referred to as “Big Bonus”, hereinafter abbreviated as “BB”) and a relatively small profit to the player There is a role that can play a predetermined number of games (referred to as “regular bonus”, hereinafter abbreviated as “RB”).

  In addition, in the current mainstream models, a combination of predetermined symbols is arranged along an activated formation line (hereinafter referred to as an “effective line”), and in order to achieve a winning in which coins, medals, etc. are paid out, A combination of symbols indicating that the winning combination of the winning combination (hereinafter referred to as “internal winning combination”) is won by a winning combination (hereinafter referred to as “internal winning combination”) and the internal winning combination (hereinafter referred to as “internal winning combination”). The player is required to perform a stop operation at a timing at which the player can stop at the active line. In other words, no matter how much internal winning is made, if the timing of the stop operation of the player is bad, a winning cannot be established. That is, gaming machines that require skill in the timing of the stop operation (the high importance of technical intervention called “to push”) are currently mainstream.

In the model exchange, for example, a decorative member that configures the appearance of the gaming machine, a control board that electrically controls the above-described reel, and the like are replaced. In addition, among members constituting the gaming machine, operation members such as a stop button and a start lever are members that are frequently operated by the player, and are frequently replaced during repair and replacement because of high failure frequency.
For this reason, in recent years, it has been desired to develop a gaming machine that takes into account that components such as control boards and operation members are exchanged in the above-described model exchange and repair exchange.

Thus, for example, there is a gaming machine in which a plurality of members among the constituent members constituting the gaming machine are combined into a unit, and these units can be replaced as a unit (see Patent Document 1).
According to the gaming machine described in Patent Document 1, in the model exchange or repair exchange, the operator only has to exchange the unit including the member that needs to be exchanged, so that the exchange work is simplified. Thereby, while being able to reduce the expense required for replacement | exchange, the working efficiency at the time of replacing | exchanging each member can be improved.

  With reference to FIG. 11, the operation of the power supply unit 66 accompanying opening and closing of the middle door 40 will be described.

  The power supply unit 66 supplies power by the power supply unit 662 based on a signal from the power supply unit 662 serving as a power supply unit that supplies power supplied from the external power supply to various devices and the middle door power switch 55. In addition to the power supply control unit 663 serving as a power supply stop unit that stops the operation, a manual switch 664 manually operated by an operator and an auxiliary power supply unit 665 are provided.

The power supply unit 662 is supplied with an AC voltage of 100 V from an external power source (not shown). The power supply unit 662 supplies power to devices constituting the gaming machine 1 such as the main control circuit 711 and the sub control circuit 721.
The auxiliary power supply unit 665 supplies power only to the middle door power switch 55 and the power supply control unit 663.

In a state where no signal is transmitted from the middle door power switch 55, the power supply control unit 663 starts or stops the power supply by the power supply unit 662 according to the operation of the manual switch 664 by the operator.
The power supply control unit 663 stops the power supply by the power supply unit 662 and starts the power supply by the auxiliary power supply unit 665 on condition that a signal is transmitted from the middle door power switch 55. Then, the middle door power switch 55 is driven.
That is, the power supply control unit 663 stops the power supply by the power supply unit 662 on the condition that the middle door power switch 55 detects that the middle door 40 is open.
The power supply control unit 663 disables the operation of the manual switch 664 by the operator while the signal is transmitted from the middle door power switch 55.

  According to the power supply unit 66 configured as described above, for example, when the operator opens the middle door 40, the middle door power switch 55 detects that the middle door 40 is opened, and the middle door 40 is opened. Is transmitted to the power supply control unit 663, and the power supply by the power supply unit 662 is stopped.

Further, for example, while the operator is opening the middle door 40, the middle door power switch 55 is driven by the electric power supplied from the auxiliary power supply unit 665 and outputs a signal indicating that the middle door 40 is in an open state. The transmission continues to the power supply control unit 663. Therefore, even if the operator operates the manual switch 664, this operation is invalidated and the power supply by the power supply unit 662 is not started.
When the operator closes the middle door 40, no signal is transmitted from the middle door power switch 55. Accordingly, the power supply unit 662 starts supplying power by operating the manual switch 664 by the operator.

The power supply unit 662 and the power supply control unit 663 as described above are provided in the power supply unit 66. As a result, for example, the worker can insert at least a part of the above-described parts covered by the middle door 40, that is, the stop buttons 7L, 7C, 7R, the stop button substrate 7B, the door relay substrate 54, the medal selector 47A, and the medal insertion. When the middle door 40 is opened in order to replace any of the mouth 22, the medal sensor 22S, the ROM cartridge 723, and the ROM cover 724, the power supply is automatically stopped. For this reason, the replacement work of these parts is not performed while the supply of electric power is continued.
Accordingly, since the replacement parts are not removed in a state where power is supplied, the replacement parts can be prevented from being damaged or broken.

  Further, since the power supply can be stopped simply by opening the middle door 40 in order to perform the replacement work, the operator does not need to operate the power supply unit 66 to stop the power supply every time the replacement work is performed. Therefore, the replacement work can be simplified.

Each of these drive circuits receives a control signal such as a drive command output from the CPU 31, and controls the operation of each actuator.

  The main input signal generating means for generating an input signal necessary for the microcomputer 30 to generate a control command includes a start switch 6S, a 1-BET switch 11, a 2-BET switch 12, a maximum BET switch 13, There are a C / P switch 14, a medal sensor 22S, a reel stop signal circuit 46, a reel position detection circuit 50, and a payout completion signal circuit 51.

  The start switch 6S detects the operation of the start lever 6 and outputs a game start command signal. The medal sensor 22S detects medals inserted into the medal insertion slot 22. The reel stop signal circuit 46 generates a stop signal (stop command signal) in response to the operation of each stop button 7L, 7C, 7R. The reel position detection circuit 50 receives the pulse signal from the reel rotation sensor and supplies a signal for detecting the position of each reel 3L, 3C, 3R to the CPU 31. The payout completion signal circuit 51 generates a signal for detecting completion of medal payout when the count value of the medal detection unit 40S (the number of medals paid out from the hopper 67) reaches the designated number data.

  In the circuit of FIG. 12, the random number generator 36 generates a random number belonging to a certain numerical range, and the sampling circuit 37 samples one random number at an appropriate timing after the start lever 6 is operated. By using the random numbers sampled in this way, an internal winning combination or the like is determined based on an internal lottery table or the like stored in the ROM 32, for example. The internal symbol combination (internal symbol combination data) is that the corresponding symbol combination and the profit given to the player are indirectly associated with each other through the stop control mode corresponding to the internal symbol combination I can say that.

  After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33. From the reels 3L, 3C, 3R, reset pulses are obtained every rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 50. The count value of the drive pulse counted in the RAM 33 is cleared to “0” by the reset pulse thus obtained. As a result, the RAM 33 stores a count value corresponding to the rotational position within one rotation range for each of the reels 3L, 3C, 3R.

  A symbol table (not shown) is stored in the ROM 32 in order to associate the rotational positions of the reels 3L, 3C, and 3R with the symbols drawn on the outer peripheral surface of the reel. In this symbol table, a code number that is sequentially given for each fixed rotation pitch of each reel 3L, 3C, 3R with reference to the rotation position where the reset pulse is generated, and a corresponding code number are provided. A symbol code indicating the displayed symbol is associated with the symbol.

  Furthermore, a symbol combination table is stored in the ROM 32. In this symbol combination table, a symbol combination corresponding to a combination, a medal payout number corresponding to the symbol combination, and a determination code thereof are associated with each other. The symbol combination table is referred to when the left reel 3L, the center reel 3C, and the right reel 3R are stopped and when the display combination is confirmed after the all reels 3L, 3C, and 3R are stopped. The display combination is a combination (established combination) corresponding to the symbol combination arranged along the display line.

  Based on the lottery process (internal lottery process, etc.) based on the random number sampling, the CPU 31 selects the operation signal sent from the reel stop signal circuit 46 at the timing when the player operates the stop buttons 7L, 7C, 7R, and the selected signal. Based on the stop table, a signal for stopping the reels 3L, 3C, 3R is sent to the motor drive circuit 39.

  In the stop mode indicating the winning combination, the CPU 31 supplies a payout command signal to the hopper driving circuit 41 and pays out a predetermined number of medals from the hopper 67. At this time, the medal detection unit 40S counts the number of medals to be paid out from the hopper 67, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 31. As a result, the CPU 31 stops driving the hopper 67 via the hopper drive circuit 41 and ends the medal payout process.

A gaming machine 201 according to the second embodiment will be described with reference to FIGS.
In the following description of the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted or simplified.

  In the gaming machine 1 according to the first embodiment, the middle door gripping portion 407 is configured such that the gripping arm portions 407A and 407B extending laterally from the edge of the reel unit support portion 409 of the middle door 40 and the tips of the gripping arm portions 407A and 407B are connected to each other. And a gripper body 407C to be connected.

  Thereby, in the gaming machine 1 according to the first embodiment, the operator can grip the grip portion main body 407C of the middle door grip portion 407 to open and close the middle door 40, but the middle door grip portion 407 is located on the side of the reel unit support portion 409. Therefore, the middle door 40 is increased in length in the width direction. For this reason, a gaming machine having a short middle door in the width direction has been desired.

  FIG. 14 is a partial perspective view showing the configuration of the back surface of the front door. Specifically, FIG. 14 is a partial perspective view showing the configuration of the middle door 240 in the rear surface of the front door of the gaming machine 201.

In the present embodiment, the configurations of the reel unit base 602 of the middle door 240 and the reel box 931 of the reel unit 273 are different from those of the first embodiment. Specifically, without providing the middle door gripping portion 407 (FIG. 3) in the first embodiment, a locking portion 607 that can be locked by the operator's finger is provided in the reel box 931 of the reel unit 273.
In addition to this difference, in this embodiment, the configurations of the main control unit support portion 508 and the reel unit support portion 509 of the middle door 240 are different from those in the first embodiment. Specifically, the configuration around the stopper insertion holes 502A, 502B, and 502C formed in the main control unit support portion 508 and the reel unit support portion 509, and the stopper 153 that is inserted into the stopper insertion holes 502A, 502B, and 502C. Is different from the first embodiment.

First, the configuration of the reel unit 273 that is different from that of the first embodiment will be described.
The reel unit 273 includes a plurality of cylindrical reels 3L, 3C, 3R, stepping motors 49L, 49C, 49R (FIG. 12) for rotationally driving the reels 3L, 3C, 3R, and the reels 3L, 3C, 3R and And a reel box 931 for accommodating stepping motors 49L, 49C, 49R.

  The reel box 931 has the same configuration as that of the reel box 731 in the first embodiment, but of the outer surfaces of the reel box 931, two surfaces that are substantially parallel to the inserted reels 3L, 3C, and 3R and are back to back. Each is provided with a locking portion 607.

These locking portions 607 are rectangular parallelepiped boxes, of which a recess 607A is formed on the surface of the reel box 931 on the flange 732 side, and an operator holds his / her finger on the bottom surface of the recess 607A. Finger insertion holes 607B that can be inserted in alignment are formed.
Of the surfaces of the locking portions 607, the surface 607C that faces the surface that contacts the side surface of the reel box 931 has a palm of the operator's palm when the operator grips the locking portions 607 as will be described later. Curved for easy adhesion.
The reel unit 273 configured in this manner is attached by tightening with a screw (not shown) in a state where the collar 732 is aligned with the collar 405 of the reel unit base 602.

The procedure for the operator to open and close the middle door 240 is as follows.
First, the operator aligns the fingers, inserts them into the finger insertion holes 607B of the locking portion 607, and bends the fingers to lock the fingers to the locking portion 607.
Next, in a state where the finger is locked to the locking portion 607, the operator can draw the hand toward the near side, thereby opening the middle door 240.

The procedure for the operator to hold the middle door 240 is as follows.
First, the operator aligns the fingers of both hands, inserts them into the finger insertion holes 607B of the locking portion 607, and bends the fingers to apply force, thereby bringing the palm into close contact with the surface 607C.
That is, the operator can hold the middle door 240 by gripping the locking portion 607 so that the finger is locked by the locking portion 607.

  That is, in the gaming machine 201 of the present embodiment, the main control unit 71 and the reel unit 273 are provided on the middle door 240, and a support portion 43 that supports the middle door 240 so as to be opened and closed is provided on the back surface of the front door body 2b. The reel unit 273 includes a plurality of cylindrical reels 3L, 3C, and 3R, stepping motors 49L, 49C, and 49R that rotationally drive the reels 3L, 3C, and 3R, and the reels 3L, 3C, 3R, and a stepping motor 49L. , 49C, 49R, and a box-shaped reel box 931 for receiving, and an outer portion of the reel box 931 is provided with a locking portion 607 on which an operator's finger can be locked.

  Therefore, according to the gaming machine 201 of the present embodiment, in addition to the same effects as the gaming machine 1 described in the first embodiment, the following effects can be achieved.

When the middle door 240 is opened / closed or transported, the operator has a locking portion 607 that can be held by locking his / her finger.
Thereby, compared with the case where the part which an operator has when opening / closing and transporting the middle door 240 is provided in a shape that can be held by hand, the locking part for the middle door 240 is provided. The size of 607 can be reduced, and the length of the middle door 240 in the width direction can be shortened.
Therefore, when the middle door 240 is closed with respect to the front door 2 and the front door 2 is closed with respect to the cabinet 60, the operator contacts the locking portion 607 with the device disposed inside the cabinet 60. Since it is not necessary to close the front door 2 while considering whether or not to do so, workability can be further improved.
That is, when the front door 2 is opened and closed, there is no need to consider the position and size of the locking portion 607 generated by the rotation trajectory of the front door 2.

  In addition, when the front door 2 is closed, the ratio of the locking portion 607 to the internal space of the cabinet 60 is small. Therefore, the layout of a plurality of devices inside the cabinet 60, the design inside the cabinet 60, etc. The degree of freedom can be improved.

  Further, in the gaming machine 201 of the present embodiment, such a locking portion 607 is provided on two surfaces of the reel box 931 that are back to back.

  Therefore, for example, when parts are replaced, the operator can further improve the workability because the middle door 240 can be stably transported with both hands by locking the fingers of both hands to the locking portions 607.

  Next, of the configurations of the stopper 153, the main control unit support portion 508, and the reel unit support portion 509, configurations different from those in the first embodiment will be described.

The left and right ends of the main control unit support 508 in FIG. 14 are respectively stopper insertion holes 502A and 502B into which the stopper 153 is inserted, and locking portions described later of the stopper 153 inserted into the stopper insertion holes 502A and 502B. Stopper guides 503 </ b> A and 503 </ b> B with which 633 is engaged are formed.
Further, at the lower end of the reel unit support portion 509 in FIG. 14, stopper insertion holes 502A and 502B and stopper guide holes 503A and 503B having substantially the same shape as the stopper insertion holes 502C and 503C are formed. The stopper insertion holes 502A, 502B, and 502C and the stopper guides 503A, 503B, and 503C will be described in detail later with reference to FIG.

The stopper 153 is a rod-like member, a stopper main body 631 that can be inserted into the stopper insertion holes 502A, 502B, and 502C, a claw 632 that is provided on the distal end side of the stopper main body 631 and can be locked to the front door main body 2b, A locking portion 633 that is provided on the base end side of the stopper main body 631 and can be locked to the middle door 240. Among these, the latching | locking part 633 is flat form so that an operator can hold | maintain.
As in the first embodiment, in the front door body 2b, the middle door 240 is closed, and the insertion portion into which the claw 632 of the stopper 153 is inserted at a position that coincides with the stopper insertion holes 502A, 502B, and 502C. Is formed, and the claw 632 of the stopper 153 is locked (not shown).

  FIG. 15 is a partial perspective view showing the configuration of the main control unit support 508 of the middle door 240. Specifically, FIG. 15 is a partial perspective view showing the stopper insertion hole 502B and the stopper guide 503B in the main control unit support portion 508 of the middle door 240. Hereinafter, the configuration of the stopper insertion hole 502B and the stopper guide 503B will be described, but the stopper insertion holes 502A and 502C and the stopper guides 503A and 503C have the same configuration.

  The stopper guide 503B is formed in an annular shape so as to surround the stopper insertion hole 502B, and protrudes in the direction in which the stopper 153 is inserted. The stopper guide 503B includes an upper guide portion 504U formed above the stopper insertion hole 502B and a lower guide portion 504D formed below.

The upper guide portion 504U is formed along an arc extending from the left to the upper side in FIG. 15 of the stopper insertion hole 502B in the circumference surrounding the stopper insertion hole 502B.
Specifically, the upper guide portion 504U is further divided into four sections, and each of the first upper guide portion 504Ua, the second upper guide portion 504Ub, and the third upper guide portion 504Uc in order from the left in FIG. The fourth upper guide portion 504Ud.
The first upper guide portion 504Ua and the third upper guide portion 504Uc are formed at a predetermined height, and the second upper guide portion 504Ub is formed lower than the first upper guide portion 504Ua and the third upper guide portion 504Uc. The fourth upper guide portion 504Ud is formed higher than the first upper guide portion 504Ua and the third upper guide portion 504Uc.

The lower guide portion 504D is formed along an arc extending from the right to the lower side in FIG. 15 of the stopper insertion hole 502B in the circumference surrounding the stopper insertion hole 502B. Specifically, the lower guide portion 504D is further divided into four sections, which are respectively a first lower guide portion 504Da, a second lower guide portion 504Db, and a third lower guide portion 504Dc in order from the right side in FIG. The fourth lower guide portion 504Dd.
The first lower guide portion 504Da and the third lower guide portion 504Dc are formed at a predetermined height, and the second lower guide portion 504Db is formed lower than the first lower guide portion 504Da and the third lower guide portion 504Dc. The fourth lower guide portion 504Dd is formed higher than the first lower guide portion 504Da and the third lower guide portion 504Dc.

Therefore, among the annular stopper guide 503B, the first upper guide portion 504Ua and the first lower guide portion 504Da located on the left and right sides in FIG. 15 of the stopper insertion hole 502B are formed at a predetermined height. Thus, the stopper 153 is a releasable posture holding portion 505 that holds a posture in a releasable state described later.
Further, among the annular stopper guide 503B, the third upper guide portion 504Uc and the third lower guide portion 504Dc located on the upper and lower sides in FIG. 15 of the stopper insertion hole 502B are formed at a predetermined height. Thus, the fixed posture holding unit 506 holds the posture of the stopper 153 in a fixed state, which will be described later.

The procedure for fixing the middle door 240 to the front door body 2b by the stopper 153 is as follows.
First, the middle door 240 is closed, and the stopper insertion hole 502B of the middle door 240 and the insertion portion of the front door body 2b are made to coincide with each other. In this state, the stopper main body 631 of the stopper 153 is inserted into the stopper insertion hole 502B, and the locking portion 633 is locked to the releasable posture holding portion 505 of the stopper guide 503B.
As a result, the stopper 153 is locked to the openable posture holding portion 505 with the stopper main body 631 inserted into the stopper insertion hole 502B, but the claw 632 is inserted into the front door main body 2b. It is made openable state that is not locked to.

Next, the stopper 153 is rotated approximately 90 ° in the clockwise direction in FIG. 15 along the stopper guide 503B, and the locking portion 633 of the stopper 153 is locked to the fixed posture holding portion 506. Then, the nail | claw 631 of the stopper 153 is latched by the insertion part of the front door main body 2b.
As a result, the stopper 153 is locked to the fixed posture holding portion 506 and the claw 632 is locked to the insertion portion of the front door body 2b with the stopper main body 631 inserted into the stopper insertion hole 502B. Set to a fixed state.

As described above, the middle door 240 can be fixed to the back surface of the front door body 2b by the stopper 153 in a state where the middle door 240 is closed.
Further, by performing this procedure in the same manner for the stopper insertion holes 502A and 502C, the middle door 240 can be reliably fixed to the back surface of the front door body 2b.

Further, when the stopper main body 631 is inserted into the stopper insertion hole 502B and the locking portion 633 is locked to the stopper guide 503B, the stopper 153 can be switched between a fixed state and an openable state.
Specifically, the operator rotates the stopper 153 by approximately 90 ° counterclockwise in FIG. 15 from the state where the locking portion 633 is locked to the fixed posture holding portion 506 of the stopper guide 503B. The portion 633 can be engaged with the releasable posture holding portion 505 of the stopper guide 503B.
Conversely, from the state in which the locking portion 633 is locked to the releasable posture holding portion 505 of the stopper guide 503B, the stopper 153 is rotated approximately 90 ° clockwise in FIG. The guide 503B can be engaged with the fixed posture holding portion 506.

As described above, of the stopper guide 503B, the fourth upper guide portion 504Ud and the fourth lower guide portion 504Dd are formed highest. Thereby, the rotation angle of the stopper guide 503B of the stopper 153 inserted into the stopper insertion hole 502B is limited.
That is, even if the stopper 153 is rotated counterclockwise in FIG. 15 from the state in which the stopper 153 can be opened, the locking portion 633 contacts the fourth upper guide portion 504Ud and the fourth lower guide portion 504Dd. This rotation is restricted.
Even when the stopper 153 is rotated clockwise in FIG. 15 from the fixed state of the stopper 153, the locking portion 633 contacts the fourth upper guide portion 504Ud and the fourth lower guide portion 504Dd. Movement is also regulated.
Therefore, the switching operation between the fixed state and the openable state of the stopper 153 by the operator is facilitated, and workability can be improved.

  That is, in the gaming machine 201 of the present embodiment, the middle door 240 is provided with a stopper 153 that fixes the middle door 240 to the back surface of the front door body 2b in the closed state. The middle door 240 has stopper insertion holes 502A, 502B, and 502C. The stopper 153 includes a stopper main body 631 that can be inserted into the stopper insertion holes 502A, 502B, and 502C of the middle door 240, and a claw 632 that is provided on the front end side of the main body 631 and can be locked to the front door main body 2b. A locking portion 633 that is provided on the base end side of the stopper main body 631 and can be locked to the middle door 240. The stopper 153 is locked by the claw 632 and the locking portion 633 so that the middle door 240 is locked to the front door main body. The fixed state fixed to the back surface of 2b and the locking part 633 are locked but the claw 632 is locked Not an open state, it is possible to switch the stopper insertion hole 502A of Midorudoa 240, 502B, near 502C, the openable position holding unit 505 for holding a posture in the open state of the stopper 153 are provided.

  Therefore, according to the gaming machine 201 of the present embodiment, in addition to the same effects as the gaming machine 1 described in the first embodiment, the following effects can be achieved.

The middle door 240 is formed with stopper insertion holes 502A, 502B, and 502C, and a stopper 153 that fixes the middle door 240 to the back surface of the front door body 2b is inserted into the stopper insertion holes 502A, 502B, and 502C; A claw 632 that can be locked to the front door body 2b and a locking portion 633 that can be locked to the middle door 240 are included.
Accordingly, the stopper 153 is inserted into the stopper insertion holes 502A, 502B, and 502C of the middle door 240, and the claw 632 is locked to the front door body 2b with the locking portion 633 locked to the middle door 240. The middle door 240 can be fixed to the back surface of the front door body 2b.

In addition, the locking portion 633 is locked to the middle door 240, but the claw 632 is not locked to the front door body 2b, and the openable state is maintained, and the posture of the stopper 153 is maintained in this openable state. The part 505 is provided on the middle door 240.
Accordingly, the posture of the stopper 153 changes from the state in which the stopper 153 can be opened, that is, the state in which the stopper main body 631 is inserted into the stopper insertion holes 502A, 502B, and 502C and the locking portion 633 is locked to the middle door 240. Can be prevented.
That is, in the first embodiment, since the parts such as the front door 2 and the middle door 40 are exchanged, when the operator opens the middle door 40, the stopper 53 rotates counterclockwise from the openable state. May end up. In this case, when the middle door 40 is closed and fixed to the front door 2b, it is necessary to return the posture of the stopper 53 to the openable state again.
However, in this embodiment, since the posture of the stopper 153 can be held by the openable posture holding portion 505, when the middle door 240 is fixed to the front door 2b, the posture of the stopper 153 is returned to the openable state again. Since no operation is required, workability can be further improved.

Further, as described above, the releasable posture holding unit 505 holds the posture of the stopper 153 in the releasable state, and the stopper 153 is moved from this state to the claw 632 and the locking portion 633, respectively. It is possible to switch to a fixed state locked to the middle door 240.
Thus, the operator inserts the stopper main body 631 into the stopper insertion holes 502A, 502B, and 502C, the middle door 240 is fixed to the front door main body 2b, and the middle door 240 is fixed to the front door main body 2b. It is possible to switch between an openable state that is not open and can be opened. Therefore, the operator can quickly perform the operation of opening / closing the middle door 240 without inserting / removing the stopper 153 into / from the stopper insertion holes 502A, 502B, 502C.
