Description

[Technical Field]

[0001] The present invention relates to a hand-pushed cart that is mainly used in gaming parlors to transport pachinko gaming machines (in this application, pachinko gaming machines may be simply referred to as "gaming machines"). [Background technology]

[0002] Pachinko machines are installed in the halls of amusement parlors on structures commonly known as islands. Before being installed on the islands, the machines are first delivered from the machine manufacturer to a warehouse, for example, at the parlor. Naturally, not just one machine is delivered to the warehouse, but multiple machines, often quite a number. The machines delivered to the warehouse are then transported from the warehouse to the hall where the island is located. The gaming machines are transported by a well-known hand-pushed cart, and are then placed in front of the island where they are installed. Similarly, carts are also used when gaming machines that have been used in the hall are removed from the islands and transported to a warehouse outside the hall. As such, carts are essential for transporting gaming machines in and out.

[0003] The applicant of the present application has filed several patent applications relating to carts suitable for transporting the gaming machines described above, and has brought the carts relating to these patent applications to the market.

[0004] The cart in the patent application filed by the applicant of the present application is specialized for carrying gaming machines. The gaming machine placed on the cart is fitted into a publicly known or well-known frame, and is placed on the cart while still fitted into the frame. The frame is a component for fixing the gaming machine to the island, and is formed by assembling boards of a specified width into a rectangle that surrounds the gaming machine from above, below, left, and right when viewed from the front. Generally, gaming machines are fitted into frames when shipped from the gaming machine manufacturer, and are handled in this state even after arriving at the gaming facility. The gaming machine placed on the cart also remains fitted into the space inside the rectangular frame. The cart has a platform, which is a plate on which the gaming machine is placed, and an upper member located directly above the platform and farther from the platform than the vertical length of the frame. The upper member has a movable member provided below the upper member and capable of moving up and down relative to the upper member. When a gaming machine surrounded by a frame is placed on the platform of a cart and the movable member is moved downward, the lower surface of the movable member is pressed against the upper surface of the frame, so that the frame (and the gaming machine fitted in the frame) are sandwiched between the upper surface of the platform and the lower surface of the movable member. Also, when the movable member is moved upward, the lower surface of the movable member moves away from the upper surface of the frame, so that the frame is no longer sandwiched between the upper surface of the platform and the lower surface of the movable member. In this way, the above-mentioned cart can fix or detach the gaming machine to or from the loading platform while the gaming machine is placed on the loading platform. By making it possible to fix or detach the gaming machine to or from the loading platform at will, when the cart is moved, the gaming machine is fixed to the loading platform of the cart to prevent the gaming machine from falling off the cart, and when loading or unloading the gaming machine, the gaming machine can be detached from the loading platform of the cart to enable this work.

[0005] [Patent Document 1] Patent Publication No. 2018-122833 [Patent Document 2] Patent Publication No. 2018-122058 [Patent Document 3] Patent Publication No. 2018-122059 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in recent years, pachinko machines have become increasingly flashy in their decoration to please the player's eyes. For example, decorations that extend upward from 30 cm to even 50 cm or more are sometimes provided on the upper front of the machine. This decoration protrudes significantly above the upper plate of the frame into which the machine is fitted, in front of the upper plate of the frame. When such a gaming machine is placed on a cart as described above and then secured to the cart, when the movable member is moved downward to secure the gaming machine to the cart, the movable member may interfere with the decoration of the gaming machine that protrudes above the upper plate of the frame, making it impossible to secure the gaming machine to the cart properly. Of course, even today, there are gaming machines that do not have decorations that protrude above the upper board of the frame. Therefore, it is preferable that the cart be one that can be detachably fixed to the frame, whether it is a gaming machine that has decorations that protrude above the upper plate of the frame or a gaming machine that does not have such decorations. However, no such cart currently exists.

[0007] To improve a cart used for transporting a game machine so that both a game machine having a decoration protruding above the upper plate of the frame and a game machine having no such decoration can be stably placed on the cart together with the frame. [Means for solving the problem]

[0008] The bogie of the present invention for solving the above problems is as follows. The present invention is a cart having a plate-shaped loading platform with a horizontal upper surface on which a gaming machine body, which is a gaming machine fixed inside a frame, is placed, and casters provided below the loading platform. The loading platform of the cart has a front and a back that correspond to the front and back orientation of the gaming machine within the gaming machine body that is planned to be placed on the loading platform, and two vertically extending pillars are erected on both the left and right sides of the position on the loading platform where the gaming machine body is planned to be placed, and at least one of the pillars can be set to either abut against a part of the gaming machine body placed on the loading platform from the rear or not, thereby providing a rearward tipping prevention means that prevents the gaming machine from tipping backward when it is in a position abutting against a part of the gaming machine body, and the two pillars are fitted with belts, at least one end of which is detachable from the pillars, that can be attached to the pillars at both ends to abut against the front of the gaming machine body placed on the loading platform, thereby preventing the gaming machine from tipping forward. This cart has a platform on which the gaming machine is placed, similar to the conventional cart described in the Background Art section. The gaming machine is placed on the cart while still fitted in a frame, as in the conventional case. The combination of the frame and the gaming machine fitted in the frame is referred to as the "gaming machine body" in this application. The platform is a plate, and its upper surface is horizontal, like the platform of a typical cart. As mentioned above, the gaming machine is fixed to the island. The island has a horizontal plate called the lower plate, on which the gaming machine is fixed along with its frame. To avoid the need to lift the gaming machine when pushing it out of the platform relative to the lower plate or pulling it out onto the platform (allowing the gaming machine to slide along the platform or the lower plate), it is preferable that the height of the top surface of the platform from the floor be the same as the height of the top surface of the lower plate from the floor. Furthermore, to accommodate the height of the lower plate, which may vary slightly depending on the amusement parlor, or to ensure that the height of the top surface of the platform and the lower plate from the floor are the same even when the floor is carpeted, it is preferable that the platform be able to move slightly up and down. The platform of the cart of the present invention has a defined front and rear. This front and rear orientation is determined to correspond to the front and rear orientation of the gaming machine among the gaming machines that are planned to be placed on the platform. Two vertically extending pillars are erected on both the left and right sides of the position on the platform where the gaming machine is planned to be placed. In other words, when the gaming machine is placed on the platform of the cart, it is positioned between two pillars. The distance between the two pillars can be equal to or slightly wider than the width of the gaming machine. By doing so, the gaming machine placed on the platform will interfere with the two pillars when attempting to tip over laterally, making it less likely to tip over laterally. The heights of the two pillars may be the same or different, but it is preferable that both be at least as high as the gaming machine itself, for example, at least 70% of the height of the gaming machine itself. If the pillars are too low, their effectiveness in preventing the gaming machine from tipping over laterally may be compromised. On the other hand, there is no point in making the pillars higher than the height of the gaming machine itself. At least one of the two pillars is provided with a backward tipping prevention means for preventing the gaming machine from tipping backward when it is in a state of contacting a part of the gaming machine body placed on the loading platform, by which it is possible to select a state in which it abuts from the rear side against a part of the gaming machine body or not. The two pillars are fitted with belts, at least one end of which is detachable from the pillars, that are attached at both ends to the pillars and come into contact with the front of the gaming machine placed on the loading platform, thereby preventing the gaming machine from tipping forward. When the cart is moved, the rearward tipping prevention means is brought into contact with a part of the gaming machine body from the rear side to prevent the gaming machine from tipping backward, and the belt, both ends of which are fixed to two pillars, has its middle part brought into contact with the front of the gaming machine body to prevent the gaming machine from tipping forward. In this way, combined with the fact that the gaming machine body is prevented from tipping left and right by the two pillars, the gaming machine body does not tip in any direction, front, back, left, or right, and can be moved by the cart in a stable state. On the other hand, when loading or unloading the gaming machine onto or from the cart, the rear tip-over prevention means is placed in a state where it does not come into contact with the gaming machine, and at least one end of the belt is removed from the pillar to which it is attached, thereby enabling the loading and unloading of the gaming machine. As mentioned above, when the cart is moved, the gaming machine is prevented from tipping over by the two pillars, the rear tipping prevention means, and the belt, but these, particularly the rear tipping prevention means and the belt, do not interfere with the decoration on the upper front side of the gaming machine, so there is no problem in stabilizing the gaming machine on the loading platform of the cart. In other words, this cart is capable of stably loading both gaming machines with decorations that protrude above the upper plate of the frame and gaming machines that do not have such decorations on the cart, along with their frames.

[0009] The cart of the present invention uses a belt as a means for preventing the gaming machine body from tipping forward. The reason for using a belt as such a means is that, as mentioned above, there may be decorations on the front of the gaming machine, and there are no uniform standards for the shape and size of those decorations. Therefore, a certain degree of flexibility is required for a means to abut against the front of the gaming machine body and prevent the gaming machine body from tipping forward, and a belt that is easily bendable is suitable for such a means. From this perspective, it is preferable that the belt be adjustable in length or be stretchable. Furthermore, the end of the belt that is intended to be attached to the pillar can be attached and detached to the pillar using Velcro (trademark) or other hook-and-loop fasteners. For example, if a hook-and-loop fastener attached to the pillar and a hook-and-loop fastener attached to a certain length on one end of the belt are detachably fastened, the length of the belt connecting the two pillars (the length of the belt that contributes to preventing the gaming machine body from tipping forward) can be adjusted by adjusting which portion of the length of the hook-and-loop fastener on one end of the belt is attached and detached from the hook-and-loop fastener on the pillar, effectively making it possible to adjust the length of the belt. In theory, the belt's effectiveness in preventing the gaming machine from tipping forward increases the higher the position at which the belt contacts the front of the gaming machine. Since the belt's path should be horizontal, or at least nearly horizontal, to prevent slack, the belt's attachment positions to the two pillars at both ends should preferably correspond to a height range of about 40% of the gaming machine's height. However, since the belt can be attached or detached at least one end to one of the two pillars to choose whether or not it will abut against the front of the gaming machine, the work of attaching and detaching the end of the belt to and from the pillar is unavoidable. However, for workers who are generally often at the front of the cart, the work of attaching and detaching the belt to and from the pillar from the front of the gaming machine does not pose a major problem in terms of workability, as it is easy to reach.

[0010] On the other hand, the cart of the present invention is provided with a backward tipping prevention means for preventing the gaming machine from tipping backward. As described above, the backward tipping prevention means is provided on at least one of the pillars and is capable of selecting a state in which it abuts from the rear side against a part of the gaming machine placed on the loading platform or not, thereby preventing the gaming machine from tipping backward when it is in a state in which it abuts against a part of the gaming machine. The backward tipping prevention means provided on the cart may be of any type as long as it can perform such a function. For example, the backward tipping prevention means may be similar to the belt described above used to prevent the gaming machine from tipping forward. However, if the backward tipping prevention means is a belt-like device, it will generally require a worker at the front of the cart to attach and detach at least one end of the belt to and from a post behind the gaming machine, which is difficult to reach, resulting in poor workability. Furthermore, because the shape and size of the rear side of the gaming machine, such as the shape and size of the rear of the frame and the shape and size of the rear of the gaming machine, are standardized to a certain extent, the backward tipping prevention means does not require the same degree of freedom in shape as a belt. From this perspective, the backward tipping prevention means can be made to be advantageous in terms of workability, and it is preferable to do so.

[0011] For example, the backward tipping prevention means may comprise a protruding body attached to the pillar so as to be capable of retracting between a first position approaching the other pillar and a second position away from the other pillar. In this case, the protruding body has a flat engaging surface that prevents the gaming machine from tipping backward by abutting against the rear surface of the frame in the gaming machine body placed on the loading platform when in the first position, and the engaging surface does not abut against the rear surface of the frame when in the second position. Note that this backward tipping prevention means may be provided on both of the two pillars. When this protruding body is in the first position, that is, when it protrudes from the column to which it is attached toward the other column, it abuts against the rear surface of the frame included in the gaming machine from the rear. This prevents the gaming machine from tipping backward. Although frames naturally vary slightly depending on the manufacturer, their sizes are standardized to a certain extent. Therefore, if the protruding body is designed to abut against the rear surface of the frame from the rear, it will be possible to abut the protruding body against the frames of most gaming machines, making it possible to prevent most gaming machines from tipping backward. The protruding body does not need to be completely immersed in the pillar when in the second position, but by immersing it in the pillar to the extent that it does not abut against the rear surface of the frame in the gaming machine body when in the second position, it can be ensured that it does not interfere with the loading and unloading of the gaming machine from the cart. Even if an operator is required to operate the protruding body to move it between the first and second positions, since the protruding body is attached to a pillar located on the side of the gaming machine body, it is possible to eliminate the need for work behind the gaming machine body, and therefore problems in terms of workability are unlikely to arise.

[0012] When the backward tipping prevention means includes a protruding body, the cart of the present invention may include a first elastic body that is an elastic body that urges the protruding body in a direction from the second position toward the first position. In this case, the protruding body that is not subjected to an external force may be positioned at the first position due to the force from the first elastic body. By doing so, when the gaming machine is placed on the cart, the protruding body can engage the rear surface of the frame in the gaming machine without any special operation by an operator, so it is possible to prevent the gaming machine placed on the cart from tipping backward without any operation by an operator. When a first elastic body is present in addition to the protruding body, the protruding body may be provided with an abutment surface that abuts against the frame in the gaming machine body and moves the protruding body toward the second position when the gaming machine body is placed on the loading platform by sliding it from the rear to the front of the loading platform. If such an abutment surface is present, for example, when loading a gaming machine attached to an island onto a loading platform from the rear, if the gaming machine is slid forward on the loading platform, the protruding body will be pushed by the abutment surface that comes into contact with the gaming machine and will naturally move from the first position to the second position against the biasing force from the first elastic body, and when the frame inside the gaming machine reaches in front of the protruding body, the biasing force from the first elastic body will cause the protruding body to automatically abut against the rear surface of the frame. As a result, when loading the gaming machine onto the loading platform from the rear, the worker only needs to push the gaming machine into the planned position, and the backward tipping prevention means, which is the protruding body, will automatically prevent the gaming machine from tipping backward, improving the workability when fixing the gaming machine to the cart. The contact surface of the protruding body can be, for example, a vertical plane that is oblique to the direction of movement of the protruding body when viewed in a plan view. When the trolley is equipped with a protruding body, it may also be equipped with a locking means for prohibiting movement of the protruding body in the second position in a direction toward the first position, and a release switch that, when operated, releases the prohibition imposed by the locking means on the movement of the protruding body in the second position in a direction toward the first position. As a result, unless the release switch is operated, the protruding and recessed body will continue to exist in the second position even if it is subjected to the force generated by the first elastic body. As a result, when the gaming machine on the cart is lowered from the rear of the loading platform (for example, this work is necessary when moving the gaming machine to the front and then transferring it from the cart to the bottom plate of the island), the protruding and recessed body will be locked onto the rear surface of the frame, preventing any hindrance to the unloading work.

[0013] The rearward tip-over prevention means can also be a rod-shaped body having a length equivalent to the distance between the two pillars and supported by an axis provided on the rear side of one of the two pillars, and which is capable of rotating around the axis in a plane perpendicular to the fore-and-aft direction of the loading platform, and which has a locking portion that can be engaged with the tip of the rod-shaped body provided on the other of the two pillars, so that when the tip of the rod-shaped body, which has become approximately horizontal by rotation around the axis, is engaged with the locking portion, the front surface of the rod-shaped body abuts against the rear surface of the gaming machine in the gaming machine body. In this case, the backward tipping prevention means is provided with a rod-shaped body, and the front of the rod-shaped body is brought into contact with the rear of the gaming machine in the gaming machine body to prevent the gaming machine from tipping backward. Although the shape and size of the front of the gaming machine vary depending on the decoration, the shape and size of the rear of the gaming machine are standardized to a certain extent, so it is relatively easy to prevent the gaming machine body from tipping backward using the rod-shaped body. Furthermore, when such a backward tip-over prevention means is adopted, the rod-shaped body must be operated at a position that is behind the gaming machine body as seen by the worker, who is often located in front of the cart; however, unlike a soft belt, it is relatively easy to operate a hard rod-shaped body. Such backward tipping prevention means including a rod-shaped body can be provided on the cart alternatively to a backward tipping prevention means having a protruding body, but can also be used in combination with a backward tipping prevention means having a protruding body. When both are provided on the cart, if the backward tipping prevention means having a protruding body can engage the rear surface of the frame in the gaming machine body, the backward tipping prevention means having a protruding body should be used preferentially, and if the rear tipping prevention means having a protruding body cannot engage the rear surface of the frame in the gaming machine body or if there is a risk that the engagement will be insufficient due to circumstances such as the shape or size of the frame being different from what was expected, then a backward tipping prevention means including a rod-shaped body can be used.

[0014] When the backward tip-over prevention means includes a rod-shaped body as described above, the rod-shaped body may have an elongated hole extending along the longitudinal direction of the rod-shaped body, be journaled by the shaft by passing the shaft through the elongated hole, and have a recess at its tip that is recessed in the longitudinal direction of the rod-shaped body, and the locking portion may be a protrusion that protrudes from the other of the two pillars toward one of the two pillars and can be fitted into the recess. In this case, by moving the rod-shaped body, which is approximately horizontal, within the elongated hole so that the shaft approaches the tip of the rod-shaped body, the recess of the rod-shaped body is moved away from the protrusion of the locking portion, and then moving the rod-shaped body within the elongated hole so that the shaft approaches the rear end of the rod-shaped body, it is possible to fit the protrusion of the locking portion into the recess of the rod-shaped body. By fitting the protrusion of the locking portion into the recess at the tip of the rod-shaped body, it is possible to ensure that the tip of the rod-shaped body is locked by the locking portion. When a recess is provided at the tip of the rod-shaped body and a protrusion is provided at the locking portion, the cart may be provided with a second elastic body that applies a force to the rod-shaped body to move the rod-shaped body toward the tip. In this way, when the protrusion of the locking portion is fitted into the recess at the tip of the rod-shaped body, a force is applied from the second elastic body to the rod-shaped body in a direction pushing the tip of the rod-shaped body toward the locking portion. This reduces the risk of the lock by the locking portion at the tip of the rod-shaped body being released at an unintended timing, and therefore reduces the risk of the gaming machine body tipping backward at an unintended timing due to such release of the lock. The recess at the tip of the rod-shaped body may be, for example, a groove, the depth of which is aligned with the length of the rod-shaped body. [Brief explanation of the drawings]

[0016] Hereinafter, first and second preferred embodiments of the bogie of the present invention will be described with reference to the drawings. In each embodiment, the same components are designated by the same reference numerals, and duplicated descriptions will be omitted as necessary.

[0017] First Embodiment First, a brief description will be given of the structure of the island in this embodiment with the gaming machines attached thereto and transported by the carts described later. 1, 300 is a gaming machine. In this embodiment, the gaming machine 300 is a pachinko gaming machine. Since the gaming machine 300 in this embodiment is a pachinko gaming machine, the island to which it is attached, which will be described later, is an island for a pachinko gaming machine. The gaming machine 300 itself, a pachinko gaming machine, is quite common. The area around the front of the gaming machine 300, indicated by the dashed line in FIG. 1, may or may not have decoration. The decoration is located in front of the frame (described below), and in some cases extends above the frame, and in other cases extends to the right of the frame. Regardless of the presence or absence of decoration, the gaming machine 300 is a typical commercially available machine. Since the gaming machine 300 is not particularly distinctive, further explanation will be omitted. Note that below the gaming machine 300, there is generally a tray for receiving balls, consisting of an upper tray and a lower tray, as well as a handle used to operate the balls. However, these are not relevant to the present invention and are well known, so they are not shown in the illustration. The gaming machine 300 is fixed inside a rectangular member called a frame 500. The frame 500 is often made of wood, but is not limited to this, and is made of metal in this embodiment. The frame 500 is made up of four boards that form the four sides when viewed from the front, and are assembled in a frame-like or rectangular shape, with the width of each board aligned in the depth direction. The gaming machine 300 is fitted into the rectangular space within the frame 500. The gaming machine 300 is fixed to the frame 500 using a known or well-known method. The integrated gaming machine 300 and frame 500 are referred to as the gaming machine body in this application. The gaming machine 300 is generally fitted into and fixed to the frame 500 from the stage of shipment from the manufacturer to the gaming facility, and this embodiment follows this example.

[0018] In a pachinko parlor, the gaming machines 300 are usually fixed to a structure called an island 400. The island 400 may be made of metal, but is often made of wood, and is structured so that a large number of gaming machines 300 can be installed in parallel. Other equipment that may be installed on the island 400 as needed include a ball lending machine that lends gaming balls to workers, a call lamp that notifies workers and hall staff of the status of the gaming machine 300, and a ball circulation mechanism that supplies balls to the ball lending machine and gaming machine 300 and also collects balls that have fallen off the gaming machine 300 and circulates the balls, but these are not shown in the figures. The gaming machine 300 fixed to the frame 500 is attached to the island 400 together with the frame 500. With the gaming machine 300 fixed to the frame 500, the frame 500 is fixed to the island 400, thereby fixing the gaming machine 300 to the island 400. The island 400 has a horizontal lower plate 401 on which the frame 500 is placed, and an upper plate 402 that is parallel to the lower plate 401 and located above the frame 500. The frame 500 is fixed to the island 400 while placed on the lower plate 401. The frame 500 is fixed to the island 400 by fixing the plate corresponding to the lower edge of the frame 500 to the lower plate 401 and the plate corresponding to the upper edge of the frame 500 to the upper plate 402, using appropriate means such as nails or dedicated metal fittings. Directly below the lower plate 401 of the island 400 is a front plate 403. The front plate 403 is a plate of a predetermined thickness whose upper and lower surfaces abut against each other, and protrudes slightly forward from the lower plate. The front end of the front plate is also configured to be slightly thicker than the rear portion. An ashtray is generally attached to the front plate 403, or a cash box storage area is provided for placing a cash box.

[0019] The cart of this embodiment is used when transporting a gaming machine 300 (more precisely, a gaming machine 300 fixed to a frame 500) from, for example, a warehouse to the front of an island 400 and attaching it to the island 400, or when removing a gaming machine 300 that has been attached to the island 400 from the island 400 and transporting it to a warehouse or the like.

[0020] The configuration of the carriage 100 will be described. FIG. 2 is a perspective view of the carriage 100 as seen obliquely from the front, and FIG. 3 is a perspective view as seen obliquely from the rear. The front and rear of the cart 100 are determined based on the front and rear of the gaming machine 300 loaded on the cart 100. The front side of the cart 100 is the front side in Fig. 2, and the rear side in Fig. 3.

[0021] Unless otherwise specified, the dolly 100 is basically made of metal. The bogie 100 includes a base 110. The base 110 supports the bogie 100 and is configured to stably support the bogie 100. In this embodiment, although not limited thereto, the base 110 is a member assembled in a U-shape in a plan view with an open front. Casters 111 are provided below the base 110 to allow the base 110, and therefore the bogie 100, to smoothly run on the floor. The casters 111 are publicly known or well-known rotatable wheels. A portion of the casters 111 is made of rubber or resin. As is widely known, the casters 111 are attached to the base 110 via a rotation axis so as to be rotatable 360° in a plan view, allowing the traveling direction of the bogie 100 to be changed.

[0022] Pillars 120 are erected from the middle of the members extending in the front-to-rear direction on both sides of the base 110. Although not limited to this, the pillars 120 in this embodiment are made of rectangular or square pipes with a cross section. The distance between the two pillars 120 is approximately the same as the width of the frame 500 in the left-to-right direction, or slightly wider. A long nut 123 having a threaded hole on its inner surface is fitted into the upper end portion of each of the columns 120 in the height direction. This results in an internally threaded hole (which may be a bottomed hole) being provided at the top end of each of the columns 120 along the length of the columns 120. A threaded portion of a bolt 124 having a head 124A with a larger diameter than the threaded portion is screwed onto the long nut 123 (see the cross-sectional view of the long nut 123 and bolt 124 in FIG. 4). Although not shown, the upper surface of the head 124A of the bolt 124 has an indentation that can be engaged with a predetermined tool. In this embodiment, the predetermined tool is, but is not limited to, a hexagonal wrench 125, and the indentation is a hexagonal cross-sectional hole that engages with the hexagonal wrench 125. The two pillars 120 are connected near their lower ends by a reinforcing plate 126 that maintains the upright position of the two pillars 120 .

[0023] The loading platform 131 is configured to include a base plate 131A and two bridge plates 131C. The platform 131 is used to place the gaming machine 300 on. Taking into consideration that the height of the lower plate 401 of the island for pachinko gaming machines is approximately 60 cm from the floor, the height of the top surface of the platform 131 from the floor is set so that when the platform 131 moves up and down together with the upper member 133, it can move up and down within a range of at least 5 cm, preferably about 10 cm, and more preferably about 15 cm, centered on a height of 60 cm from the floor. Increasing the range of this up and down movement is useful for making the cart 100 compatible with not only pachinko gaming machines but also pachislot gaming machines. The gaming machines 300 placed on the loading platform 131 can be moved onto the lower plate 401 of the island 400 as described below, and the gaming machines 300 placed on the lower plate 401 of the island 400 can be placed onto the loading platform 131 as described below. The loading platform 131 is configured to withstand the weight of the gaming machines 300 placed thereon. The above-mentioned base plate 131A plays a role in supporting the weight of the gaming machines 300. The base plate 131A is a plate material that is rectangular in plan view, although it is not limited to this. Its width is slightly wider than the width of the gaming machine 300 (more precisely, the width of the frame 500 to which the gaming machine 300 is fixed), its length in the front-to-rear direction is greater than the length of the gaming machine 300 in the front-to-rear direction (more precisely, the length of the frame 500 to which the gaming machine 300 is fixed in the front-to-rear direction), and its thickness is, although not limited to this, thinner than the thickness of the lower plate 401 attached to the island 400.

[0024] The bridge plate 131C is connected to the rear end of the base plate 131A. The bridge plate 131C is used to move the gaming machine 300, which is placed on the base plate 131A and fitted in the frame 500, from the loading platform 131 to the lower plate 401 of the island 400 over the front plate 403 of the island 400, or from the lower plate 401 of the island 400 to the loading platform 131 over the front plate 403 of the island 400. Both bridge plates 131C are elongated, rectangular plates in a plan view and have essentially the same configuration. As described below, the bridge plate 131C is long enough to straddle the portion of the front plate 403 that protrudes from the lower plate 401, in other words, longer than the length of the portion of the front plate 403 that protrudes from the lower plate 401. The bridge plate 131C is thinner than the thickness of a typical lower plate 401. The bridge plate 131C has a width that allows the bridge plate 131C to have sufficient rigidity to withstand the weight of the gaming machine 300 and other components when the gaming machine 300 and the frame 500 are slid over the bridge plate 131C. In this embodiment, two bridge plates 131C are provided, one attached near each end of the base plate 131A in the width direction. This allows the two bridge plates 131C to support the frame 500 from below near each end of the width direction. The two bridge plates 131C are narrow and spaced apart in this manner in order to prevent the bridge plate 131C from interfering with obstacles, such as an ashtray, on the front plate 403 of the island 400 when the bridge plate 131C straddles the front plate 403. However, the number of bridge plates 131C does not need to be two, and may be three or more, as long as the frame 500 in which the gaming machine 300 is fitted can slide stably over it. Alternatively, if there is no need to avoid obstacles or if there is another way to avoid obstacles, it is possible to use a single bridge plate 131C that is wide, for example, approximately the width of the base plate 131A. In this embodiment, both bridge plates 131C are hinged at their front ends to the rear ends of the base plate 131A near both widthwise ends by a known or well-known method, although detailed illustration is omitted. As a result, both bridge plates 131C are rotatable about their base ends as axes between two positions: a position (use position) where their upper surfaces can be made to form a continuous plane with the upper surface of the base plate 131A (although it is possible for the bridge plates 131C to be rotated to a position where they are inclined slightly rearward (downward toward the front plate 403) relative to the base plate 131A, but this is not limited thereto, in this embodiment, the bridge plates 131C can only be rotated downward to an angle where their upper surfaces are made to form a continuous plane with the upper surface of the base plate 131A), and a position (transport position) where their rear ends are raised so that the above-mentioned plane that can be made to form a continuous plane with the upper surface of the base plate 131A is perpendicular to the upper surface of the base plate 131A. For example, the bridge plate 131C in Figures 2, 3, and 7 is in the use position, and the bridge plate 131C in Figure 8 is in the transport position. Although not limited to this, in this embodiment, the bridge plate 131C in the use position is manually moved to the transport position by an operator. The same is true for the reverse movement. Although not limited to this, in this embodiment, the two bridge plates 131C can each independently take the use position and the transport position. 12, circular holes 131C2 and 131C3 of the same size are drilled near the ends of both bridge plates 131C, for example, in the center in the width direction, at positions corresponding to when the bridge plate 131C is in the use position in a plan view. A nut 131C4 with a threaded inner surface is fixed to a portion of the bridge plate 131C abutting the periphery of hole 131C3 at a position corresponding to holes 131C2 and 131C3 when the bridge plate 131C is in the use position in a plan view. A bolt 131C5 with a threaded outer surface is threadedly engaged with the nut 131C4. The head of the bolt 131C5 is exposed below the lower hole 131C3 in the bridge plate 131C. The bolt 131C5 has a concave / convex portion at its upper end that can be engaged with a predetermined jig, such as a hexagonal wrench 131C6, inserted through the upper hole 131C2 in the bridge plate 131C. This allows the bolt 131C5 to be moved up and down by rotating the hexagonal wrench 131C6.

[0025] The loading platform 131 described above is indirectly connected to the columns 120 by fixing both widthwise ends of its base plate 131A to the lower ends of two connecting plates 132 that extend vertically along the front surfaces of the two columns 120. Both connecting plates 132 are thin plates that extend vertically. Although not limited to this, the width of the two connecting plates 132 in this embodiment is approximately the same as the width of the columns 120. A connecting fitting 131D that is approximately L-shaped in plan view is used to fix the connecting plate 132 to the base plate 131A. Both the fixing of the connecting fitting 131D to the base plate 131A and the fixing of the connecting fitting 131D to the connecting plate 132 can be appropriately performed by a publicly known method, such as screwing or welding.

[0026] An upper member 133 is attached to the upper ends of both pillars 120. The above-mentioned connecting plate 132 is attached to the lower side of the upper member 133. The two upper members 133 are attached to the upper ends of the pillars 120, and can be moved up and down relative to the pillars 120 and positioned at an appropriate height using a mechanism described below. This allows the two connecting plates 132 attached to the upper members 133 to also be moved up and down along the two pillars 120 and positioned at an appropriate height. As a result, the loading platform 131 and base plate 131A connected to the connecting plates 132 can also move up and down, and can be fixed at an appropriate height. Each of the two upper members 133 is roughly rectangular parallelepiped, and has a hole (not shown) on the front side that opens downward and is used to insert the upper end of the column 120. The horizontal cross section of the hole corresponds to the cross-sectional shape of the column 120. A hole 133A, which may be circular, but is not limited to this, is drilled in the top surface of the upper member 133. The upper member 133 is attached to the upper end of the pillar 120 by inserting the upper end of the pillar 120 into the above-mentioned hole in the upper member 133. Because the cross sections of both pillars 120 and the cross sections of the holes in both upper members 133 correspond to each other, the two upper members 133 are guided by the pillars 120 and can only move in the vertical direction. How this movement and the positioning of the height of the upper member 133 are performed will be explained using Figure 4. As described above, long nuts 123 are fitted into the upper end portions of both columns 120 in the height direction, and bolts 124 are screwed into the long nuts 123. The heads 124A of the bolts 124 are positioned directly below the aforementioned holes 133A formed in the upper surface of the upper member 133. The diameter of the heads 124A of the bolts 124 is larger than the diameter of the holes 133A in the upper member 133. Therefore, as shown in FIG. 4(A), the plate having the holes 133A that close the upper side of the upper member 133 is supported from below by the heads 124A of the bolts 124. As a result, the upper member 133 is supported from below by the heads 124A of the bolts 124. On the other hand, the tip of the hexagonal wrench 125, which is the predetermined tool described above, can be inserted through the hole 133A provided in the upper member 133. The tip of the inserted hexagonal wrench 125 can be inserted into the recessed or protruding portion (the hexagonal cross-sectional hole) provided in the head 124A of the bolt 124, thereby engaging the hexagonal wrench 125 with the head 124A of the bolt 124 (FIG. 4(B)). Rotating the hexagonal wrench 125 left or right in this state moves the bolt 124 up or down. This also moves the upper member 133, which is supported from below by the head 124A of the bolt 124, up or down. As a result, the vertical position (height position) of the upper member 133 can be changed, and the upper member 133 can be positioned at any desired height. FIG. 4(C) shows the case where the height position of the upper member 133 is lowered from that shown in FIG. 4(A), but it is of course possible to raise the height position of the upper member 133 from that shown in FIG. 4(A). In this embodiment, adjustment of the height position of the upper member 133 must be performed individually for each of the upper members 133. However, if the difference in the height positions of the upper members 133 becomes too large, it may cause problems such as distortion of the upper member 133. Therefore, when adjusting the height position of the upper member 133, care should be taken to ensure that the difference in the height positions of the upper members 133 does not become too large. It is not necessary to use the bolts 124 as described above to move the upper member 133 up and down relative to the column 120 and to position the height position of the upper member 133. It is also possible to use power generated by a power generating device such as a motor or hydraulic pump to move the upper member 133. In the above example, the movement of the upper member 133 causes the platform 131 and the upper member 133 to move in the same direction and the same distance in tandem, but it is also possible to move the platform 131 up and down independently of the movement of the upper member 133. Considering that the upper member 133 moves up and down, the hole 133A into which the hexagonal wrench is inserted should be located at a height in the range of approximately 145 cm to 155 cm from the floor, so that the worker can easily turn the hexagonal wrench.

[0027] Although not shown, a locking metal fitting is attached to the front surface of the upper member 133 provided at the upper end of each of the two pillars 120. The locking metal fitting is a metal fitting for detachably connecting to belt fittings 172 attached to both ends of belt 171. The belt 171 is a strip made of a flexible material, for example, a flexible and durable cloth, and in this embodiment has a uniform width along its entire length. The length of the belt 171 is set so that, when the belt metal fittings 172 at both ends are detachably connected to the two locking metal fittings, the belt 171 abuts against the front surface (front surface of the gaming machine 300) of the gaming machine body (combined gaming machine 300 and frame 500) placed on the base plate 131A, and the belt 171 is tensioned to a degree that prevents the gaming machine body from tipping forward. The belt 171 may be provided with a buckle or other known or well-known means for adjusting the length, and may be stretchable to a degree that does not affect the effectiveness of preventing the gaming machine body from tipping forward. In any case, by such means, the belt 171 can be effective in preventing the gaming machine body from tipping forward, regardless of the shape and size of the gaming machine 300, which may be caused by, for example, the type or presence of decorations. Furthermore, the belt 171 does not need to be configured so that at least one end thereof can be detachably fixed to at least one of the pillars 120 by a combination of the belt metal fittings 172 and the locking metal fittings. It is also possible to use Velcro (trademark) or other hook-and-loop fasteners (not shown) to detach the one end of the belt 172 that is intended to be attached to the pillar 120. For example, if a hook-and-loop fastener (not shown) attached to the pillar 120 is detachably fastened to a hook-and-loop fastener attached over a certain length range on one end of the belt 171, the length of the belt 171 connecting the two pillars 120 (the length of the range of the belt 171 that contributes to preventing the gaming machine from tipping forward) can be adjusted by determining which portion of the length of the hook-and-loop fastener on one end of the belt 171 is attached to or detached from the hook-and-loop fastener provided on the pillar 120, which effectively makes it possible to adjust the length of the belt 171.

[0028] In this embodiment, a protruding / recessed body 181 is attached to the front side of each of the pillars 120. The two protruding / recessed bodies 181 are provided on the two pillars 120 in a mirror image relationship, for example. Note that the protruding / recessed body 181 may be provided on only one of the pillars 120. The protruding-recessed body 181 is a member that can move between a first position where it protrudes from the pillar 120 on which it is provided toward the other pillar 120, and a second position where it moves away from the other pillar 120. When the protruding-recessed body 181 is in the first position, the front surface of the protruding-recessed body 181 abuts against the rear surface (rear surface of the frame 500) of the gaming machine body (combination of the gaming machine 300 and the frame 500) placed on the base plate 131A, thereby preventing the gaming machine body from tipping backward. On the other hand, when the protruding-recessed body 181 is in the second position, the protruding-recessed body 181 does not abut against the rear surface of the frame 500, and does not abut against the frame 500. The configuration and function of the protruding-recessed body 181 will be explained using the perspective view of Fig. 5 and the front and rear views of Fig. 6. As described above, the protruding-recessed body 181 is movable between a first position and a second position, but is provided with a locking mechanism that prevents the protruding-recessed body 181 from moving toward the first position when it is in the second position. Fig. 6(A) shows a rear view of the protruding-recessed body 181 when the locking mechanism is OFF (as seen from the outside of the pillar 120), Fig. 6(B) shows a front view of the protruding-recessed body 181 when the locking mechanism is OFF (as seen from the inside of the pillar 120), Fig. 6(C) shows a rear view of the protruding-recessed body 181 when the locking mechanism is ON, and Fig. 6(D) shows a front view of the protruding-recessed body 181 when the locking mechanism is ON.

[0029] The protruding body 181 is a rectangular prism-shaped metal member that is trapezoidal in plan view and extends vertically. The protruding body 181 is hollow. In Figure 5, the protruding body 181 is in the first position. The surface at the back that is hidden in Figure 5 is the surface that abuts against the rear surface of the frame 500 included in the gaming machine body, and is the locking surface referred to in the present invention. The locking surface 182 appears in Figure 6. When viewed from above, the tip side of the protruding body 181 (the left side of Figure 5) has a shape that looks like it has been cut off by a straight line that is diagonal to the line connecting the front and rear directions of the cart 100. The vertical surface that includes this diagonal line as its side is the abutting surface 183. Due to the presence of the contact surface 183, when the gaming machine attached to the island 400 is loaded onto the loading platform 131 from the rear side of the loading platform 131, if the gaming machine is slid forward on the loading platform, the projecting / retracting body 181 will naturally move from the first position to the second position as it is pushed by the contact surface 183 that comes into contact with the frame 500 included in the gaming machine. In other words, the projecting / retracting body 181 moves in the same way as a publicly known or well-known latch on a door. The protruding-recessed body 181 is housed in a case body 184 that has the function of attaching the protruding-recessed body 181 to the pillar 120 while it is housed therein. The case body 184 has an internal space with a width equivalent to the vertical width of the protruding-recessed body 181, and the protruding-recessed body 181 is guided by the case body 184 and is able to move horizontally within the internal space. The case body 184 has ribs 187 that protrude upward and downward. The ribs 187 are used to secure the case body 184 to the pillar 120. Holes are drilled in the ribs 187, and the case body 184 can be secured to the pillar 120 by, for example, passing a screw through the hole and threading it into the pillar 120. A first elastic body 186, which is an elastic body, but is not limited to this, a spring in this embodiment, more specifically a coil spring, is housed inside the case body 184. The first elastic body 186 always applies a force to the protruding / retracting body 181 housed in the case body 184 in the leftward direction in FIG. 5, in other words, in a direction that moves the protruding / retracting body 181 from the second position to the first position.

[0030] A rectangular hole 181A is drilled in the surface of the protruding / recessed body 181 facing the pillar 120, although this is not limited to this. The significance of this hole 181A will be described later. A circular hole (not shown) is provided on a surface of case body 184 that abuts against the surface opposite to the surface where hole 181A of protruding / recessed body 181 is formed, and is not limited to this. This hole is for rotatably supporting a switch member, which will be described later. Switch member 185 is configured to include switch shaft 185A rotatably supported in the circular hole provided in case body 184, a rectangular plate-like knob 185B, and is provided at the end of switch shaft 185A on the back side of case body 184 in FIG. 5, and a rectangular plate-like locking piece 185C, and is provided at the end on the opposite side of switch shaft 185A, and is not limited to this. The knob 185B is operated by an operator to rotate the switch member 185, and may be any knob that allows the operator to perform an appropriate operation to rotate the switch member 185 by gripping it or the like. The locking piece 185C is intended to limit, or lock, the movement of the protruding and recessed body 181. When viewed from the longitudinal extension of the switch shaft 185A, the locking piece 185C is attached to the switch shaft 185A so that it overlaps with the knob 185B. The knob 185B is rotatable between the vertical position shown in FIG. 6(B) and the horizontal position shown in FIG. 6(D). When the knob 185B is positioned in the vertical position, the locking piece 185C is in the vertical state shown in FIG. 6(A), and when the knob 185B is positioned in the horizontal position, the locking piece 185C is in the horizontal state shown in FIG. 6(C). When locking piece 185C is in the vertical position, locking piece 185C does not come into contact with the edge of rectangular hole 181A provided in protruding-recessed body 181, regardless of whether protruding-recessed body 181 is in the first position, the second position, or somewhere between them (FIG. 6(A)). Therefore, when tab 185B and locking piece 185C are in the vertical position, protruding-recessed body 181 receives force from first elastic body 186 and always tries to be located in the first position, but when it receives an external force that resists the force from first elastic body 186, it can move from the first position to the second position, and when the external force is removed, it naturally returns from the second position to the first position due to the biasing force from first elastic body 186. When locking piece 185C is in a horizontal position, the tip of locking piece 185C comes into contact with the right edge in Fig. 6(C) of rectangular hole 181A provided in protruding-recessed body 181. This prevents protruding body 181 from case body 184, restricting movement from the second position, i.e., locking it in the second position. By rotating the knob 185B from horizontal to vertical, the locking piece 185C is rotated from horizontal to vertical, and the protruding and recessed body 181 is unlocked and allowed to move between the first position and the second position.

[0031] A rod-shaped body 191 is attached to the rear surface of the upper member 133 located at the top end of the left-hand pillar 120 in Fig. 3. The rod-shaped body 191 is made of a thin square pipe in this embodiment, although not limited to this, and its length is set to be approximately equal to the distance between the two pillars 120. In this embodiment, although not limited to this, the rod-shaped body 191 is supported near its base end by a shaft 192 formed by a bolt fixed to the column 120 by screwing its tip into the column 120. The rod-shaped body 191 is able to rotate about the shaft 192, and can rotate at least between the position hanging straight down as shown in Figures 2 and 3 and the approximately horizontal position as shown in Figures 7 and 8, where the tip of the rod-shaped body 191 is located near the upper end of the column 120 on the side where the base end of the rod-shaped body 191 is not supported. Near the base end of rod-shaped body 191, there is drilled elongated hole 193, which is a hole for receiving pivotal support by shaft 192 described above (see Figures 3 and 9). This elongated hole 193 has a certain length along the length of rod-shaped body 191. Rod-shaped body 191 can not only rotate around shaft 192 inserted into elongated hole 193, but can also slide along the length of rod-shaped body 191 by the length of elongated hole 193 while being guided by shaft 192. At the tip of the rod-shaped body 191, a recess is provided whose depth is in the longitudinal direction of the rod-shaped body 191, and more specifically, although not limited to this, in this embodiment, a groove 194 is provided which extends in the width direction of the rod-shaped body 191 (see Figure 3). 13 is a cross-sectional view illustrating the internal configuration of rod-shaped body 191. A rotating plate 191X, which is a plate that rotates together with rod-shaped body 191 and shaft 192, is fixed to shaft 192 that supports rod-shaped body 191. Furthermore, a partition plate 191Y, which is a plate that divides the interior of rod-shaped body 191 into a distal end side and a proximal end side in the length direction, is provided inside rod-shaped body 191, closer to the distal end than the part of rod-shaped body 191 that is supported by shaft 192. A second elastic body 191Z, which is a compressed spring, is provided between rotating plate 191X and partition plate 191Y. As a result, a force that attempts to slide toward the distal end side is always applied to rod-shaped body 191 from second elastic body 191Z.

[0032] Of the two pillars 120, the pillar 120 to which the rod-shaped body 191 is not attached has a locking portion 197 on the rear surface of the upper member 133 for locking the rod-shaped body 191. The locking portion 197 is a recess, or more specifically a protrusion that fits into the inside of the groove 194, and is, for example, a cylindrical rod in this embodiment, although it is not limited to this. By inserting the locking portion 197, which is a rod, into the groove 194 at the tip of the rod-shaped body 191, the tip of the rod-shaped body 191 is locked near the upper end of the pillar 120 on the opposite side to where the rod-shaped body 191 is attached.

[0033] The method of using the cart 100 according to the first embodiment described above and its operation will now be described. First, a case will be described in which the gaming machine 300 is transported on the cart 100 from a warehouse or the like to a hall where the island 400 is located, and after the gaming machine 300 is moved from the cart 100 to the island 400, the gaming machine 300 is fixed to the island 400.

[0034] When loading the gaming machine body, which is the frame 500 to which the gaming machine 300 is fixed, onto the cart 100, the bridge plate 131C is tilted to the use position. When this operation is performed, the protruding / retracting body 181 is in an unlocked state. In other words, both the knob 185B and the locking piece 185C are in a vertical position (FIGS. 6(A) and 6(B)). When no external force is applied, the protruding / retracting body 181 is located in the first position by the biasing force applied by the first elastic body 186. In this state, the frame 500 to which the gaming machine 300 is fixed is placed on the bridge plate 131C. At this time, the front of the gaming machine 300 (the side where the board surface with nails is located) should face the front of the cart 100. After the gaming machine 300 is placed on the bridge plate 131C, the gaming machine 300 is slid forward.

[0035] The gaming machine moves forward and rests on the base plate 131A. Eventually, the frame 500 in the gaming machine comes into contact with the contact surface 183 of the protruding / retracting body 181 at the first position. If the gaming machine continues to move forward on the cart 100, the contact surface 183 is pushed outward in the width direction of the base plate 131A, causing the protruding / retracting body 181 to move outward in the width direction of the base plate 131A. In other words, the protruding / retracting body 181 moves from the first position to the second position. If the gaming machine is moved forward in this state, the frame 500 in the gaming machine will climb over the protruding-retractable body 181 and move forward of the protruding-retractable body 181. When the frame 500 moves forward of the protruding-retractable body 181, the abutment surface 183 of the protruding-retractable body 181 will no longer be in abutment with the frame 500 and will no longer receive force from the frame 500. Then, the protruding-retractable body 181 will receive force from the first elastic body 186 and return from the second position to the first position. When the protruding-retractable body 181 is located at the first position, the locking surface 182 of the protruding-retractable body 181 will be in abutment with the rear surface of the frame 500. The position where the locking surface 182 of the protruding-retractable body 181 abuts with the rear surface of the frame 500 is the position where the gaming machine is scheduled to be placed on the loading platform 131, and the gaming machine will slide forward until it reaches that scheduled position. As a result, the rear surface of the frame 500 included in the gaming machine is locked to the locking surface 182 of the projecting / retracting body 181, and the gaming machine is prevented from tipping over backward.

[0036] It may be possible that the locking surface 182 of the projecting / retracting body 181 cannot be properly abutted against the rear surface of the frame 500 due to circumstances such as the shape or size of the frame 500 being different from that of a typical machine. In such cases, the rod-shaped body 191 is used to prevent the gaming machine from tipping backward. To do this, the rod-shaped body 191 is rotated so that the groove 194 at the tip of the rod-shaped body 191 is locked with the locking portion 197 provided on the top of the pillar 120 on the side to which the rod-shaped body 191 is not attached (see Figures 7 and 8). This operation is performed as follows. First, rod-shaped body 191 is rotated around shaft 192 so that the tip of rod-shaped body 191 approaches the upper end of the pillar 120 on the side to which rod-shaped body 191 is not attached, and is made approximately horizontal. Next, as shown by arrow 1 in FIG. 9 , rod-shaped body 191 is slid toward the base end side, which is journaled by shaft 192. A force is applied to rod-shaped body 191 from second elastic body 191Z toward its tip side, but by applying a force against this force, rod-shaped body 191 moves back slightly toward the base end side. Then, groove 194 at the tip of rod-shaped body 191 faces locking portion 197 provided on the upper part of pillar 120 on the side to which rod-shaped body 191 is not attached. Then, rod-shaped body 191 is advanced toward its tip side as shown by arrow 2 in FIG. 9 , and locking portion 197 is inserted into groove 194. In this state, a force is applied to the rod-shaped body 191 from the second elastic body 191Z in a direction that moves the rod-shaped body 191 forward toward its tip. Therefore, there is little risk that the locking portion 197 will come off the groove 194. The front surface of the rod-shaped body 191 abuts against the rear surface of the gaming machine body, usually the rear surface of the gaming machine 300 included in the gaming machine body. There may be some gap between the gaming machine body and the rod-shaped body 191. As a result, the gaming machine body is locked by the rear surface of the protruding and recessed body 181 or the rod-shaped body 191, and is prevented from tipping over backward.

[0037] Next, the belt 171 is wound around the front of the gaming machine. Specifically, the belt fittings 172 on both ends of the belt 171 are detachably fastened to two locking fittings (not shown) provided near the upper ends of the two pillars 120. The belt 171 then contacts the front of the gaming machine placed on the base plate 131A, more specifically, the front of the gaming machine 300. At this time, the belt 171 is tensioned to a degree that prevents the gaming machine from tipping forward. If necessary, or if the belt 171 has a mechanism for adjusting its length, the length of the belt 171 may be adjusted. Note that the order of the process of winding the belt 171 around the front of the gaming machine and the process of positioning the rod-shaped body 191 at the rear of the gaming machine does not matter. As a result, the gaming machine is prevented from tipping backward by the protruding member 181 or the rod-shaped member 191, from tipping forward by the belt 171, and from tipping left and right by the pillars 120 located on the left and right of the gaming machine. In other words, the gaming machine is placed stably on the loading platform 131 and is unlikely to tip forward, backward, left or right. Then, the two bridge plates 131C are each flipped up to the transport position (FIG. 8).

[0038] In this state, the worker moves the cart 100 carrying the gaming machine 300 from the warehouse or the like to the hall where the island 400 is located. During this process, the gaming machine body mounted on the loading platform 131 is stable as described above. In addition, the bridge plate 131C is raised to a substantially vertical position, which prevents the bridge plate 131C from interfering with chairs or the like in the narrow hall. The cart 100 is moved by the worker holding a predetermined location of the cart 100 or the gaming machine 300 fixed to the frame 500 mounted thereon, and pushing and pulling the cart 100 while walking. During transportation, the front side of the cart 100 does not need to be the front side in the direction of travel of the cart 100.

[0039] Next, the worker positions the cart 100 facing the part of the island 400 where the gaming machine 300 is to be attached. Then, as necessary, the upper member 133 is moved up or down to align the height of the platform 131 and the lower plate 401 of the island 400. However, since the height of the lower plate 401 of each island 400 in an amusement center is often the same, it is not necessary to adjust the height of the upper member 133 at this point and it can be done at any time. Specifically, the upper member 133 is moved up or down so that the height of the rear end of the bridge plate 131C continuing from the rear end of the upper surface of the base plate 131A of the platform 131 and the front end of the lower plate 401 of the island 400 are aligned. To raise or lower the upper member 133, as shown in Figure 4(B), the tip of the hexagonal wrench 125 is inserted through the hole 133A provided at the top end of the upper member 133 of each pillar 120 to engage with the head 124A of the bolt 124, and in this state the hexagonal wrench 125 is rotated in either the left or right direction. This causes the bolt 124 to move in either the up or down direction, and accordingly the upper member 133, which is locked from below by the head 124A of the bolt 124, moves up or down. This causes the loading platform 131 attached to the upper member 133 to move up or down together with the upper member 133. After the adjustment of the height of the platform 131 by adjusting the height of the upper member 133 is completed, the following process is carried out. When the protruding body 181 has prevented the gaming machine body from tipping backward, the knob 185B of the protruding body 181 is operated to lock the protruding body 181. As already mentioned, when the knob 185B is turned sideways to turn the locking piece 185C sideways, the tip of the locking piece 185C comes into contact with the right edge of the rectangular hole 181A provided in the protruding body 181 in Figure 6(C), and the protruding body 181 is fixed in the second position (Figures 6(C) and (D)). Furthermore, when the rod-shaped body 191 is preventing the gaming machine body from tipping backward, the locking portion 197 is removed from the groove 194 at the tip of the rod-shaped body 191, and the rod-shaped body 191 is rotated around the shaft 192 so that the locking portion 197 hangs down directly below the shaft 192. To remove the locking portion 197 from the groove 194, the rod-shaped body 191 is simply slid slightly toward its base end. Next, at least one end of the belt 171 is removed from the pillar 120. This allows the gaming machine to move forward and backward on the platform 131. Furthermore, the two bridge plates 131C are tilted to the use position, and the rear ends of the upper surfaces of the bridge plates 131C and the front ends of the upper surfaces of the lower plate 401 of the island 400 are butted against each other. In addition, the steps of locking the protruding and retracting body 181, returning the rod-shaped body 191 to its downward position, removing at least one end of the belt 171 from the pillar 120, and tilting the bridge plate 131C to its use position may be performed in any order as long as they are performed before the bridge plate 131C and the lower plate 401 are butted together.

[0040] In any case, as a result of the above, the bridge plate 131C straddles the front plate 403, which protrudes forward of the island 400 from below the tip of the lower plate 401. If an obstacle such as an ashtray is present on the front plate 403 at this time, positioning it between the two bridge plates 131C prevents interference between the obstacle and the bridge plate 131C. As described above, the thickness of the bridge plate 131C is generally smaller than the thickness of the lower plate 401. If the thickness of the bridge plate 131C is excessively smaller than the thickness of the lower plate 401, or if the positioning accuracy of the height of the loading platform 131 is somewhat lacking, it may be impossible to align the rear end of the upper surface of the bridge plate 131C with the front end of the upper surface of the lower plate 401, as shown in Fig. 12(A), for example. In this case, a hexagonal wrench 131C6 is inserted through the upper hole 131C2 of the bridge plate 131C, and its front end is engaged with the upper end of the bolt 131C5. In this state, the hexagonal wrench 131C6 is rotated to move the nut 131C4 forward or backward, thereby adjusting the length of the bolt 131C5 protruding below the bridge plate 131C. By setting this to an appropriate length, for example, by abutting the lower end of the bolt 131C5 against the upper surface of the front plate 403 as shown in FIG. 12(B), the rear end of the upper surface of the bridge plate 131C and the front end of the upper surface of the lower plate 401 can be aligned in a stable state. In other words, the bolt 131C5, nut 131C4, etc. at the tip of the bridge plate 131C are intended to adjust the height of the tip of the bridge plate 131C by changing the length of protrusion from the lower surface of the bridge plate 131C. Of course, other configurations, such as a ratchet mechanism, can be used instead of the bolt 131C5 and nut 131C4, etc., as long as such an effect can be obtained. Furthermore, by enabling the height of the tip of the bridge plate 131C to be adjusted by operating it from the top surface of the bridge plate 131C, as shown in FIG. 12, the operator can easily adjust the height of the tip of the bridge plate 131C.

[0041] In this state, the worker slides the gaming machine body from the platform 131 onto the bridge plate 131C, then moves it onto the lower plate 401, and finally pushes it into a predetermined position on the lower plate 401. After that, the worker fixes the gaming machine 300 to the island 400. Such a fixing method may be publicly known or may be based on a well-known technique.

[0042] Next, we will explain how to remove the gaming machine 300 from the island 400, transport the gaming machine 300 on the cart 100 from the hall where the island 400 is located to a warehouse or the like, and then remove the gaming machine 300 from the cart 100 and store it in the warehouse or the like. However, this work is basically the reverse of the work described above when installing the gaming machine 300 on the island 400. We will explain this in a moment.

[0043] First, the operator releases the fixing of the gaming machine 300 to the island 400. This release of fixing may be performed by a publicly known or well-known technique. Next, the worker positions the cart 100 in front of the gaming machine 300 to be removed from the island 400 and faces the island 400. Next, the worker adjusts the vertical position of the loading platform 131 on the cart 100 as necessary. The method for adjusting the height of the loading platform 131 is the same as in the case described above. Also, the height of the loading platform 131 is adjusted so that the height of the rear end of the bridge plate 131C and the front end of the lower plate 401 of the island 400 are the same as in the case described above. Then, the two bridge plates 131C are tilted to the use position, and their rear ends are aligned with the front ends of the lower plate 401, respectively. In this state, the worker slides the gaming machine body placed on the lower plate 401 from the lower plate 401 onto the bridge plate 131C and moves it onto the loading platform 131. At any point during this operation, the lock on the projecting and retracting body 181 is released. As described above, the gaming machine body is prevented from tipping backward by the protruding and recessed body 181 or the rod-shaped body 191, from tipping forward by the belt 171, and from tipping left and right by the pillar 120. Then, the worker flips up the bridge plate 131C and moves it to the transfer position.

[0044] Then, the worker moves the cart 100 carrying the gaming machine 300 from the hall where the island 400 is located to a warehouse or the like. The process of transporting the gaming machine 300 can be carried out in the same manner as described above. Next, a description of the work of the worker unloading the gaming machine body from the cart 100 will be omitted. The work of unloading the gaming machine 300 in the warehouse can basically be the same as the procedure when moving the gaming machine 300 from the island 400 to the cart 100.

[0045] Second Embodiment The bogie 101 in the second embodiment will be described. The bogie 101 in the second embodiment is almost the same as the bogie 100 in the first embodiment, and differs from the bogie in the first embodiment only in that it is provided with a coupling mechanism, which will be described later. The connecting mechanism will be described with reference to FIGS.

[0046] The connecting mechanism is composed of a connecting fitting 710 and a connecting pin 720 . A connecting fitting 710 is provided on the front surface of each of the pillars 120 of the bogie 101, and a connecting pin 720 is provided on the rear surface of each of the pillars 120 of the bogie 101. The connecting pin 720 is, for example, a bolt, and has a shaft and a head portion at the tip of the shaft that is thicker than the shaft. Connecting fitting 710 has an elongated hole 711 that extends in the vertical direction, and is attached to pillar 120 by passing bolt 712, which is screwed into pillar 120, through elongated hole 711. Because bolt 712 is not tightened too tightly, connecting fitting 710 is able to move up and down relative to pillar 120 by the length of elongated hole 711. The position of connecting fitting 710 when it is at its highest position will be referred to as the upper position, and the position of connecting fitting 710 when it is at its lowest position will be referred to as the lower position. The connecting fitting 710 has an outwardly projecting locking groove 713. The locking groove 713 is a generally U-shaped groove that is open downward.

[0047] When two carriages 101 are arranged side by side with their front and rear reversed and their adjacent columns 120 adjacent to each other, the front and rear surfaces of the two columns of the adjacent carriages 101 are lined up side by side. In this state, when the connecting fitting 710 of one carriage 101 is positioned in the lower position, the connecting pin 720 fits into the groove of the locking groove portion 713 of the connecting fitting 710. On the other hand, when the connecting fitting 710 is moved to the upper position in this state, the connecting pin 720 comes out of the locking groove portion 713. When both of the connecting fittings 710 provided on the adjacent pillars 120 of the two carts 101 arranged side by side as described above are lowered to the lower position, the connecting fittings 710 and the connecting pins 720 are engaged on both the front and rear sides of the two adjacent pillars 120 ( FIG. 11(A) ). In this state, an operator can move the two connected carts 101 together, for example, with any side of them facing forward. At this time, a force that would bend the two carts 101 when viewed from above at their connected portion may be applied. However, because the connecting fittings 710 and the connecting pins 720 are engaged on both the front and rear sides of the adjacent pillars 120, there is little risk of the connecting fittings 710 bending or the connecting pins 720 coming out of the grooves of the locking groove portions 713 of the connecting fittings 710. When it becomes necessary to disconnect the two carts 101, such as when the cart 101 arrives in front of a warehouse or island 400, the two connecting fittings 710 at the front and rear of the adjacent pillars 120 are moved to the upper position. This causes the connecting pins 720 to come out of the grooves of the locking groove portions 713, and the connection between the two carts is released (FIG. 11(B)). [Explanation of symbols]
