In the embodiment, four horse models 4 are provided. Although not shown in FIG. 1, each of the horse models 4 travels on the floor board 3 by being pulled by a traveling device below the floor board 3 by a magnetic force. In this game apparatus 1, a horse racing game is executed. In the horse racing game, the horse model 4 runs so as to draw an ellipse or a substantially quadrangle as shown by the phantom lines in FIG. Although not shown, the horse model 4 may be run so as to draw lines that cross each other.

  FIG. 2 is a perspective view of the game apparatus 1 with the floor board 3 and the horse model 4 removed. A second floor plate 6 on which the traveling device travels is horizontally supported by a frame 2 a fixed to the column 2. A charging device 5 for charging the traveling device is attached to the frame 2a. Two rectangular parallelepiped blocks 7 are placed on the second floor board 6. The floor board 3 is supported by a plurality of brackets 8 and blocks 7 at the upper end of the pillar 2.

  As shown in FIG. 3, a traveling device 10 is arranged in the space between the floor board 3 and the second floor board 6. The game apparatus 1 according to the embodiment is provided with four traveling apparatuses 10 corresponding to the four horse models 4, but only one traveling apparatus 10 is shown in FIG.

<Running device>
Details of the traveling device 10 will be described with reference to FIGS. 3 to 13. The traveling device 10 includes a main body 12 capable of traveling and a power supply assembly 30 attached to the main body 12. The main body 12 includes an upper portion 14 and a lower portion 16, and the upper portion 14 and the lower portion 16 are connected by a suspension 18. As best shown in the bottom view of FIG. 10, a pair of casters 20 are attached to both ends in the longitudinal direction of the lower portion 16, and a pair of wheels 22 are attached to both ends in the transverse direction of the lower portion 16. It is attached. The caster 20 and the wheels 22 allow the traveling device 10 to travel on the second floor board 6.

  As best shown in the plan view of FIG. 9, a pair of casters 24 are attached to both ends of the upper portion 14 in the longitudinal direction, and a pair of drive wheels 26 are attached to both ends of the upper portion 14 in the transverse direction. Is attached. These drive wheels 26 are each rotated by a separate wheel motor 28 fixed to the upper part 14. The rotation of the wheel motor 28 is transmitted to the drive wheel 26 corresponding to the wheel motor 28 by a gear train (not shown). Instead of the gear train, another appropriate power transmission mechanism, for example, a mechanism using a belt and a pulley, or a mechanism using a chain and a sprocket may be used.

  As shown in FIG. 3, the upper portion 14 of the main body 12 holds a power supply assembly 30 in which one or more rechargeable power supply devices are arranged. A drive circuit board 32 on which a drive circuit for driving the wheel motor 28 to rotate the drive wheel 26 is supplied by power from the power supply device of the power supply assembly 30 is fixed inside the upper portion 14.

  The traveling device 10 as a whole is attracted upward, that is, toward the floor plate 3 by a magnetic force acting between model pulling portions 34 and 36 described later and the pulled portions 52 and 54 of the model assembly 40. For this reason, the wheel of the caster 24 and the drive wheel 26 are in contact with the upper floor board 3. When the driving wheel 26 rotates, the traveling device 10 travels in the direction indicated by the arrow in FIG. 3 due to frictional contact between the driving wheel 26 and the floor board 3. Thus, the wheel motor 28 and the drive wheel 26 are travel mechanisms that can travel by the power supply assembly 30. However, instead of the drive wheel 26, other suitable traveling means such as a caterpillar, an arm having a link mechanism, or a leg having a link mechanism may be used.

  Since the separate wheel motors 28 rotate the drive wheels 26 respectively, it is possible to rotate both the drive wheels 26 at different rotational speeds, and the traveling device 10 bends due to the speed difference of the drive wheels 26. be able to. The casters 20 and 24 facilitate the direction change of the traveling device 10. The shaft of the wheel motor 28 can rotate in both directions, and the traveling device 10 can move forward and backward. By rotating both drive wheels 26 in opposite directions, the traveling device 10 can rotate around the vertical axis on the spot.

  A model assembly 40 is disposed on the floor board 3. The model assembly 40 includes a carriage 42, a pair of wheels 44 that are rotatably attached to the carriage 42, a caster 46 that is rotatably attached to the carriage 42, a column 48 that stands on the carriage 42, and a column And a horse model 4 attached to 48. Further, a jockey model 50 is on the horse model 4. Two towed parts 52 and 54 are arranged inside the carriage 42. The to-be-towed parts 52 and 54 are ferromagnetic bodies or magnets, preferably permanent magnets.

  On the other hand, model towing portions 34 and 36 are attached to the upper portion 14 of the main body 12 of the traveling device 10. The model pulling portions 34 and 36 are ferromagnetic materials or magnets, and are preferably permanent magnets. The floor board 3 is formed of a non-magnetic material, and the model towing unit 34 of the traveling apparatus 10 and the towed part 52 of the model assembly 40 are attracted by a magnetic force so that the model towing unit 36 of the traveling apparatus 10 and the model assembly 40 are covered. The traction part 54 is attracted by the magnetic force. Therefore, when the traveling device 10 travels, the model pulling portions 34 and 36 attract the model assembly 40 so that the model assembly 40 travels together with the traveling device 10. In the preferred embodiment, the model tow portions 34, 36 and the towed portions 52, 54 are permanent magnets, but other options can be employed.

  As described above, the traveling device 10 travels under the floor board 3, and the model assembly 40 corresponding to the traveling apparatus 10 is pulled by the traveling apparatus 10 and travels on the floor board 3 as indicated by an arrow in FIG. 3. .

  As shown in FIGS. 5 and 11, the power supply assembly 30 includes a substantially rectangular parallelepiped casing 56 and a cover panel 58 attached to the casing 56. In the housing 56, one or more (two in the illustrated embodiment) power supply devices 60 are arranged. Each power supply device 60 is a rechargeable power supply device, for example, a capacitor or a secondary battery. As shown in FIG. 11, a through hole 61 is formed in the housing 56, and the power supply device 60 can be seen from the outside through the through hole 61.

  Although the wiring in the power supply assembly 30 is not illustrated, the charging device 5 (FIG. 1 or 2) is connected to these power supplies on the outer surface of the cover panel 58 (the surface opposite to the surface attached to the housing 56). A pair of charged electrodes 62 and 64 formed from a conductor for charging the device 60 are exposed. One of the charged electrodes 62 and 64 is a positive electrode, and the other is a negative electrode. When the plurality of power supply devices 60 are in the housing 56, these charged electrodes 62 and 64 are commonly used for the plurality of power supply devices 60.

  As shown in FIG. 11, power supply electrodes 66 and 68 made of a conductor are attached to the inner surface of the cover panel 58 (the surface attached to the housing 56). The power supply electrode 66 is disposed above the housing 56, and the power supply electrode 68 is disposed below the housing 56. One of the power supply electrodes 66 and 68 is a positive electrode, and the other is a negative electrode. When a plurality of power supply devices 60 are in the housing 56, these power supply electrodes 66 and 68 are used in common for the plurality of power supply devices 60.

  As shown in FIG. 5, a power supply assembly chamber 70 into which a casing 56 of the power supply assembly 30 is fitted is provided on the upper portion 14 of the main body 12 of the traveling device 10. Above and below the power supply assembly chamber 70, first fixing portions (power supply assembly holding mechanisms) 72 and 74 that are ferromagnetic bodies or magnets are disposed, and these are fixed to the upper portion 14 of the main body 12. Yes. Further, power supply electrodes 76 and 78 made of a conductor are disposed above and below the power supply assembly chamber 70, and these are fixed to the upper portion 14 of the main body 12.

  The power supply electrodes 66 and 68 (FIG. 11) of the power supply assembly 30 are second fixing portions that are ferromagnetic bodies or magnets. The first fixing portions 72 and 74 removably fix the power supply electrodes (second fixing portions) 66 and 68 provided in the power supply assembly 30. The housing 56 of the power supply assembly 30 is inserted into the power supply assembly chamber 70 of the main body 12, and the power supply electrodes 66 and 68 are fixed to the first fixing portions 72 and 74, whereby the power supply assembly 30 is held by the main body 12. Is done. When the first fixing portions 72 and 74 fix the power supply electrodes 66 and 68, the power supply electrodes 76 and 78 are in contact with the power supply electrodes 66 and 68. Although wiring in the main body 12 is not illustrated, when the power supply electrodes 76 and 78 come into contact with the power supply electrodes 66 and 68, the drive circuit of the drive circuit board 32 (FIG. 3) Power is supplied from 60 to drive the wheel motor 28 to run the traveling device 10.

  In this configuration, the first fixing portions 72 and 74 of the traveling device 10 detachably fix the power supply electrodes 66 and 68 provided on the power supply assembly 30 by magnetic force. When the power supply assembly 30 is held by the first fixing portions 72 and 74 of the traveling device 10, the power supplied electrodes 76 and 78 of the traveling device 10 are connected to the power supply electrodes 66 and 66 of the power supply device 60 provided in the power supply assembly 30. 68, the main body 12 of the traveling device 10 is powered by the power supply device 60 and can travel. According to this configuration, since electric power is not supplied to the traveling device 10 by frictional contact with the floor board, it is possible to reduce the possibility of power supply failure to the traveling device 10.

  In a preferred embodiment, the first fixing portions 72 and 74 are permanent magnets, the power supply electrodes 76 and 78 are made of a material having higher conductivity, and the power supply electrodes as the second fixing portions are used. 66 and 68 are made of ferromagnetic and highly conductive materials such as iron or steel. In this embodiment, since the power supply electrodes 66 and 68 function as the second fixing portion, the number of components is reduced as compared with the case where the second fixing portion and the power supply electrodes 66 and 68 are provided separately. Can be reduced. In addition, since the electrode is provided at the fixing portion, it is possible to reduce the risk of electrode contact failure.

  However, other options can be employed. For example, the first fixing portions 72 and 74 may be ferromagnetic materials, and the power supplied electrodes 76 and 78 that are the second fixing portions may be magnets. The power supply assembly 30 may be provided with the second fixing portion and the power supply electrodes 66 and 68 separately.

  As shown in FIGS. 4, 5, and 8, the outer surface of the cover panel 58 (the surface opposite to the surface attached to the housing 56) is ferromagnetic between a pair of charged electrodes 62 and 64. The third fixing portion 80 that is a body or a magnet is exposed. The third fixing portion 80 is detachably fixed to the external charging device 5 (FIG. 1 or 2) by magnetic force. When the third fixing portion 80 of the power supply assembly 30 is fixed to the charging device 5 and pulled by the charging device 5, the power supply assembly 30 is separated from the traveling device 10 and is held by the charging device 5. In this configuration, the power supply assembly 30 can be easily detached from the traveling device 10 by magnetic force by the external charging device 5. When the external charging device 5 holds the power supply assembly 30, the external charging device 5 can charge the power supply device 60 by the charged electrodes 62 and 64.

  12 and 13 show a part of the traveling device 10 in a cutaway manner. As shown in FIGS. 12 and 13, the traveling device 10 includes a power supply assembly locking mechanism that can lock the power supply assembly 30 fitted in the power supply assembly chamber 70. The power supply assembly locking mechanism is a pin 82 attached to the upper part 14 of the main body 12 of the traveling device 10, a lever 84 that can rotate around the pin 82, and the above-described ferromagnetic material or magnet fixed to the lever 84. The model pulling portions 34 and 36 and a lock piece 86 extending downward from the model pulling portion 34 are provided. When the lever 84 is rotated around the pin 82, the model pulling portions 34 and 36 and the lock piece 86 fixed to the lever move around the pin 82.

  As best shown in FIG. 5, a lock hole 88 is formed in the upper surface of the housing 56 of the power supply assembly 30. As shown in FIG. 12, when the model assembly 40 is directly above the traveling device 10 and the towed parts 52 and 54 are close to the model towing parts 34 and 36 with the floor plate 3 interposed therebetween, The model pulling parts 34 and 36 are lifted by the magnetic force acting on the parts 52 and 54 and the model pulling parts 34 and 36. At this time, the lock piece 86 is not engaged with the lock hole 88, and the power supply assembly 30 can be extracted from the power supply assembly chamber 70 of the main body 12 against the magnetic force acting between the power supply assembly 30 and the main body 12.

  On the other hand, as shown in FIG. 13, when the model assembly 40 is separated from the traveling device 10, particularly the model towing parts 34 and 36, the magnetic force acting on the towed parts 52 and 54 and the model towing parts 34 and 36 is weakened or eliminated. The model pulling parts 34 and 36 are lowered by gravity. At this time, since the lower end of the lock piece 86 is inserted into the lock hole 88, the power supply assembly 30 cannot be extracted from the power supply assembly chamber 70 of the main body 12.

  As described above, when the model assembly 40 is separated from the model pulling portions 34 and 36 (FIG. 13), the power supply assembly locking mechanism locks the power supply assembly 30. Therefore, when a person carries the traveling device 10 separated from the model assembly 40 for repair or the like, the power supply assembly 30 is inadvertently detached from the power supply assembly chamber 70 and the power supply assembly 30 is removed from the main body 12 or from the power supply assembly 30. The main body 12 does not fall off. On the other hand, when the model assembly 40 is in a position where the model towing parts 34 and 36 and the towed parts 52 and 54 are attracted (FIG. 12), the power supply assembly locking mechanism releases the lock to the power supply assembly 30 and The power supply assembly 30 can be extracted from the assembly chamber 70.

  As best shown in FIGS. 4 and 5, the lever 84 of the power assembly locking mechanism is located between both drive wheels 26. It is possible to manually rotate the lever 84 (release mechanism) by pinching the lever 84 or the model pulling portion 34 by hand. Therefore, even when the model assembly 40 is separated from the model pulling portions 34 and 36 and the power supply assembly locking mechanism locks the power supply assembly 30, it is necessary to remove the power supply assembly 30 such as repair of the traveling device 10. In the scene, the lock to the power supply assembly 30 by the power supply assembly locking mechanism can be manually released.

  As best shown in FIGS. 4, 5, and 9, a pair of rotation stoppers 90 for preventing the lever 84 from rotating too much are fixed to the upper portion 14 of the main body 12. A stopper piece is fixed as a part of the lever 84 on both sides of the model pulling portion 34. When the lever 84 is rotated counterclockwise in FIG. Therefore, the rotation stopper 90 restricts the lever 84 from being rotated too far and thus the model towing portions 34 and 36 from being lifted too much, thereby preventing the model towing portions 34 and 36 and the floor board 3 from coming into contact with each other, and the model towing portions 34 and 36. The magnetic force acting between the towed parts 52 and 54 is prevented from becoming excessive.

<Control system of game device>
With reference to FIG. 14, the outline of the control system of the game apparatus will be described. The control system of the game device includes an overall control device 100, a position signal supply device 102, a first light emitting device 104, and a second light emitting device 106. The overall control device 100 is a computer and controls the entire game device including the plurality of traveling devices 10 and the charging device 5. In the illustrated embodiment, a single overall control device 100 is used. However, the control device receives a signal from the position signal supply device 102 and controls the first light emitting device 104 and the second light emitting device 106. And the control apparatus which controls the charging device 5 while receiving the signal from the charging device 5 may be provided separately.

  The position signal supply device 102 supplies a signal indicating the position of each traveling device 10 (preferably, the direction of each traveling device 10 in addition to the position) to the overall control device 100. The position signal supply device 102 may be any suitable type of device capable of outputting a position signal. For example, a device that identifies the position of the traveling device 10 can be used by image analysis.

  Alternatively, the position signal supply device 102 is, for example, a pressure distribution detection device described in International Publication WO06 / 106714, Japanese Unexamined Patent Application Publication No. 2007-218892, Japanese Unexamined Patent Application Publication No. 2005-164448, Japanese Unexamined Patent Application Publication No. 2005-156474. Can be used for specifying the position of the traveling device 10. With reference to FIG. 15, an example of a position signal supply apparatus 102 that performs position specification using electromagnetic coupling will be described.

  As shown in FIG. 15, the position signal supply device 102 includes a plurality of first loop conductors 130 and second loop conductors 132. Each of the first loop conducting wires 130 has two conducting wire portions parallel to each other, and these conducting wire portions are connected at one end (the left end in the figure). The right end of the first loop conductor 130 is connected to a current supply source (not shown), and a current flows through the first loop conductor 130. These first loop conductors 130 are arranged in parallel to each other and are provided in the same layer.

  Each of the second loop conducting wires 132 has two conducting wire portions parallel to each other, and these conducting wire portions are connected at one end (the upper end in the figure). The lower end of the second loop conducting wire 132 is connected to a current measuring device (not shown). These second loop conductors 132 are arranged in parallel to each other and are provided in the same layer.

  When viewed from the direction perpendicular to the paper surface of FIG. 15, the parallel conductor portion of the second loop conductor 132 is orthogonal to the parallel conductor portion of the first loop conductor 130. However, although not shown, the layer in which the second loop conducting wire 132 is arranged is different from the layer in which the first loop conducting wire 130 is arranged, and these layers are arranged in parallel and between these layers. Has a non-conductive layer.

  When a current flows through the first loop conductor 130, a current also flows through the second loop conductor 132 due to electromagnetic coupling. The current flowing through the second loop conductor 132 when the detected piece 108 made of a conductor is placed at the intersection of the first loop conductor 130 and the second loop conductor 132 and when it is not present. Is different. Therefore, the position of the detected piece 108 is specified by monitoring the current flowing through the second loop conductor 132. If the two detection pieces 108 are provided in each traveling device 10, the angle of each traveling device 10 is also specified.

  As shown in the bottom view of FIG. 10, a pair of disc-shaped detection pieces 108 made of a conductor are fixed to the bottom surface of the lower portion 16 of the main body 12 of the traveling device 10. Therefore, the position signal supply device 102 supplies a signal indicating the positions of the two detected pieces 108 for each traveling device 10 to the overall control device 100. By specifying the positions of the two detected pieces 108 of each traveling device 10 using the signal from the position signal supply device 102, the overall control device 100 can identify the position and angle of each traveling device 10. it can. Further, when the plurality of traveling devices 10 are moved at different times and the current flowing through the second loop conductor 132 is measured, the positions of the two detected pieces 108 of each moved traveling device 10 are specified. The position signal supply device 102 can be disposed on the second floor board 6.

  As described above, since the upper portion 14 and the lower portion 16 of the main body 12 of the traveling apparatus 10 are connected by the suspension 18, a downward force is applied to the lower portion 14. For this reason, the detected piece 108 is pressed toward the second floor board 6 and thus the position signal supply device 102.

  The first light emitting device 104 emits light in a certain wavelength region (for example, visible light) for simultaneously starting the operations of all the traveling devices 10. The overall control device 100 causes the first light emitting device 104 to emit light according to the computer program.

The second light emitting device 106 transmits a traveling control signal for controlling the traveling of each traveling device 10 after activation of the traveling device 10 by light (for example, infrared rays) in a wavelength region different from the light emitted by the first light emitting device 104. To do. The overall control device 100 supplies a traveling control signal for controlling the plurality of traveling devices 10 to the second light emitting device 106 according to the computer program, and the second light emitting device 106 emits light according to the traveling control signals. Each traveling control signal is provided with identification information for identifying the traveling device 10 to be controlled, and the traveling device 10 can recognize a traveling control signal that is addressed to itself. Instead of the light emitting devices 104 and 106, a communication device using a wireless communication method using other radio waves can be used.
Preferably, the second floor plate 6 (see FIGS. 1 to 3) having high light transmittance is used, and the first light emitting device 104 and the second light emitting device 106 are disposed below the second floor plate 6. May be. However, when the light transmittance of the second floor board 6 is low, the first light emitting device 104 and the second light emitting device 106 may be arranged between the floor board 3 and the second floor board 6.

  As shown in the bottom view of FIG. 10, two first optical sensors 110 and two second optical sensors 112 are exposed on the bottom surface of the lower portion 16 of the main body 12 of the traveling device 10. The first optical sensor 110 is, for example, a visible light sensor, and outputs a light reception signal when receiving light emitted from the first light emitting device 104. The second optical sensor 112 is, for example, an infrared sensor, and outputs a travel control signal transmitted by light emitted from the second light emitting device 106. In the illustrated embodiment, two first light sensors 110 and two second lights are provided so that other sensors can receive light even if the light reaches one sensor. A sensor 112 is provided. However, a single first photosensor 110 and a single second photosensor 112 may be provided. Three or more first photosensors 110 and three or more second photosensors 112 may be provided.

  As shown in FIG. 14, each traveling device 10 further includes a CPU (central processing unit) 114, a power supply control circuit 116, and a coin battery 118. The coin battery 118 always supplies power to the first photosensor 110 so that the first photosensor 110 can output a light reception signal. When the power supply control circuit 116 receives the light reception signal from the first optical sensor 110 by the light emission of the first light emitting device 104, the CPU 114, the second optical sensor 112, and both of the CPU 114 from the power supply device 60 of the power supply assembly 30. Power supply to the wheel motor 28 is made possible.

  After the power supply device 60 starts supplying power to these elements, the second photosensor 112 transmits the travel control signal transmitted from the second light emitting device 106 to the CPU 114. The CPU 114 selects a traveling control signal for the traveling device 10 to which the CPU 114 belongs from among traveling control signals for the plurality of traveling devices 10, and controls both wheel motors 28 in accordance with the traveling control signal.

  The traveling control signal designates the rotational speed or rotational angle of each wheel motor 28. As a result, the rotational speed of each driving wheel 26 is controlled for one traveling device 10. If the rotational speeds of both drive wheels 26 are the same, the traveling device 10 goes straight, otherwise the traveling device 10 turns and advances.

  The CPU 114 is mounted on the drive circuit board 32 shown in FIG. 3, and the power supply control circuit 116 is mounted on the power supply control circuit board 120 shown in FIG. FIG. 6 shows a state where the panel 122 is removed from the upper part 14 of the main body 12 of the traveling device 10. The coin battery 118 can be attached to and detached from the main body 12 by removing the panel 122.

<Charging device>
Next, the charging device 5 of the game apparatus 1 according to the embodiment will be described with reference to FIGS. 16 to 35. The charging device 5 includes a main base 140, a power supply assembly replacement mechanism 200, and a power supply assembly holder 300. The power supply assembly holder 300 includes a charging mechanism, and the charging mechanism charges the other four power supply assemblies 30 at a time while the power supply assembly 30 is held in each of the four traveling devices 10. The power supply assembly replacement mechanism 200 replaces the four power supply assemblies 30 with the other four power supply assemblies 30.

  As best shown in FIG. 22, the main base 140 includes a bottom wall 141, a pair of side walls 142 parallel to each other, and a rear wall 143. As shown in FIGS. 19 to 21, guide rails 144 and 145 are attached to each of the side walls 142 of the main base 140. These guide rails 144 and 145 extend in the front-rear direction in parallel with each other. The power supply assembly exchanging mechanism 200 is supported by the main base 140 so as to be movable in the front-rear direction (advancing and retracting direction), and the guide rails 144 and 145 guide the movement of the power supply assembly exchanging mechanism 200 in the front-rear direction.

  As shown in FIGS. 23 to 26, the power supply assembly exchanging mechanism 200 includes a base plate 202, four bars 204 fixed to the base plate 202, and four power supply assemblies attached to the front ends of these bars 204, respectively. A fixing portion 206 is provided. Each of the power supply assembly fixing portions 206 is a fixing portion that can fix the third fixing portion 80 (FIGS. 4, 5, and 8) provided on the power supply assembly 30 of the traveling device 10 by magnetic force. Although other options may be employed, in a preferred embodiment, the third anchor 80 of the power supply assembly 30 is a ferromagnetic material and the power assembly anchor 206 is a magnet chuck.

  As shown in FIGS. 27 and 28, the power supply assembly fixing portion 206, which is a magnet chuck, has a permanent magnet 206A and a yoke 206B in which the magnet 206A is rotatably incorporated. The magnet 206A is rotated by a crank. Each crank has a crank 217 that extends parallel to the bar 204 and moves relative to the bar 204. The crank 217 includes a first link 218 and a second link 220 that is connected to the magnet 206A and rotates the magnet 206A as the first link 218 moves.

  In the state where the crank 217 shown in FIG. 27 is retracted, the magnetic force of the magnet 206A does not act on the outside. In the state where the crank 217 shown in FIG. 28 is advanced, the magnet 206A rotates 90 degrees with respect to the state shown in FIG. 27, and the magnetic force of the magnet 206A acts on the outside. According to this configuration, the magnetic force of the magnet chuck can be controlled by rotating the magnet 206 </ b> A by the crank 217. Therefore, the adhesion of the power supply assembly 30 by the magnetic chuck can be mechanically made effective or released.

  27 and 28, two cranks 217 are provided on both sides of the single bar 204. However, only a single crank 217 may be provided on the single bar 204. In the embodiment, as best shown in FIG. 24, the rightmost bar 204 and the leftmost bar 204 are provided with a single crank 217 and the two central bars 204 have two cranks. 217 is provided.

  As shown in FIGS. 23 to 26, a motor base 207 is fixed to the base plate 202 of the power supply assembly exchanging mechanism 200, and the crank 217 is driven to the motor base 207 to fix the power supply assembly fixing portion 206. A crank motor 208 is attached to enable and disable the magnetic force. A coupling 210 shown in FIG. 24 is attached to the rotating shaft of the crank motor 208, and a crankshaft 212 is attached to the coupling 210. The crankshaft 212 is connected to the crank connector bracket 216 via a bearing 214. The proximal ends of the first links 218 of the crank 217 are connected to the crank connector bracket 216. Accordingly, when the rotating shaft of the crank motor 208 rotates, the crankshaft 212 rotates, and the first link 218 moves back and forth together with the crank connector bracket 216 with respect to the base plate 202, thereby fixing the power supply assembly. The magnetic force acting on the outside from the portion 206 becomes effective and ineffective.

  As shown in FIG. 24, a detected piece 222 used to determine the validity / invalidity of the magnetic force of the power supply assembly fixing portion 206 is fixed to the crank connector bracket 216 of the power supply assembly replacement mechanism 200. On the other hand, sensors 224 and 225 capable of detecting the detected piece 222 are attached to the base plate 202 of the power supply assembly replacement mechanism 200. Each of the sensors 224 and 225 is, for example, a photo interrupter.

  When the detected piece 222 moves forward together with the crank 217 and the crank connector bracket 216, the detected piece 222 reaches the sensor 224 and is detected. The detection of the detected piece 222 by the sensor 224 is referred to as the sensor 224 being turned on. The ON signal of the sensor 224 indicates that the magnetic force of the power supply assembly fixing portion 206 is effective. That is, the sensor 224 is a magnetic force effective detection sensor for the power supply assembly fixing portion.

  When the detected piece 222 moves backward together with the crank 217 and the crank connector bracket 216, the detected piece 222 reaches the sensor 225 and is detected. The detection of the detected piece 222 by the sensor 225 is referred to as the sensor 225 being turned on. The ON signal of the sensor 225 indicates that the magnetic force of the power supply assembly fixing portion 206 is invalid. That is, the sensor 225 is a magnetic force invalid detection sensor 225 for the power supply assembly fixing portion.

  Signals from various sensors in the charging device 5 including the sensors 224 and 225 are transmitted to the overall control device 100 in order to control the charging device 5.

  As shown in FIGS. 19 to 21, the entire power supply assembly exchanging mechanism 200 is supported so as to be movable back and forth with respect to the main base 140. As shown in FIG. 23, side plates 226 are attached to both ends of the base plate 202, and upper plates 228 are attached to the upper portions of the side plates 226, respectively. A roller 230 is rotatably attached to each of the side plates 226, and a roller 232 is rotatably attached to each of the upper plates 228. As shown in FIGS. 19 and 20, the roller 230 is disposed between the guide rails 144 and 145 of the main base 140 and rolls on the guide rail 144. The roller 232 rolls in contact with the guide rail 145.

  As shown in FIGS. 18 and 22, a motor base 149 is fixed to the bottom wall 141 of the main base 140, and the motor base 149 is used for an exchange mechanism for moving the power supply assembly exchange mechanism 200 back and forth. A motor 149A is attached. The base end of the rotor 153 is attached to the rotation shaft of the exchange mechanism motor 149A, and the roller 153A is attached to the tip of the rotor 153. A box-shaped bracket 236 is fixed to the lower surface of the base plate 202 of the power supply assembly exchanging mechanism 200, and the roller 153A is disposed inside the bracket 236. Therefore, when the rotating shaft of the replacement mechanism motor 149A rotates, the rotor 153 rotates, and the entire power supply assembly replacement mechanism 200 moves back and forth with the bracket 236 relative to the main base 140.

  As shown in FIGS. 23 and 24, detected pieces 240 and 242 used for determining the position of the power supply assembly replacement mechanism 200 in the front-rear direction are fixed to the base plate 202 of the power supply assembly replacement mechanism 200. ing. On the other hand, as shown in FIG. 22, sensors 156 and 158 capable of detecting the detected piece 240 and a sensor 160 capable of detecting the detected piece 242 are attached to the bottom wall 141 of the main base 140. Each of the sensors 156, 158, and 160 is, for example, a photo interrupter.

  When the base plate 202 of the power supply assembly exchanging mechanism 200 moves to the front limit position, the detected piece 240 reaches the sensor 156 and is detected. The detection of the detected piece 240 by the sensor 156 is referred to as the sensor 156 being turned on. The ON signal of sensor 156 indicates that base plate 202 is in the forward limit position. That is, the sensor 156 is a front limit position detection sensor for the power supply assembly exchange mechanism.

  When the base plate 202 of the power supply assembly replacement mechanism 200 is retracted to the rear limit position, the detected piece 242 reaches the sensor 160 and is detected. The detection of the detected piece 242 by the sensor 160 is referred to as the sensor 160 being turned on. The ON signal of the sensor 160 indicates that the base plate 202 is at the rear limit position. That is, the sensor 160 is a rear limit position detection sensor for the power supply assembly exchange mechanism.

  When the base plate 202 of the power supply assembly changing mechanism 200 is at a predetermined position between the front limit position and the rear limit position, the detected piece 240 is detected by the sensor 158. The detection of the detected piece 240 by the sensor 158 is referred to as the sensor 158 being turned on. While the base plate 202 is retreating from the front limit position to the rear limit position, an ON signal of the sensor 158 when the sensor 158 passes the detected piece 240 is charged by the power supply assembly 30 fixed to the power supply assembly fixing portion 206. For this reason, it is held at a port described later. As will be described later, the ON signal of the sensor 158 at this time is used as an opportunity to invalidate the magnetic force of the power supply assembly fixing portion 206. That is, the sensor 158 is a position detection sensor capable of charging the power supply assembly.

  As shown in FIG. 29, the power supply assembly holder 300 includes a base frame 302 and nine walls 304 supported by the base frame 302. The eight power supply assemblies 30 can be held in the ports 303 </ b> A and 303 </ b> B that are spaces between the walls 304. As will be described later, eight chargers for charging the power supply assembly 30 are arranged in each of the ports 303A and 303B.

  The eight ports 303A and 303B are classified into four first ports 303A and four second ports 303B. The first port 303A and the second port 303B are alternately arranged in the horizontal direction. Each of the ports 303A and 303B can hold the power supply assembly 30, but as shown in FIG. 20, the power supply assembly 30 is held in each of the second ports 303B and these power supply assemblies 30 are charged. The power supply assembly 30 held and charged by the first port 303A is attached to the traveling device 10 away from the first port 303A. On the other hand, when the power supply assembly 30 is held in each of the first ports 303A and these power supply assemblies 30 are charged, the power supply assembly 30 held and charged in the second port 303B is discharged from the second port 303B. Attached to the traveling device 10 at a distance.

  Charging electrodes 306 and 308 for charging the power supply device 60 (see FIGS. 5 and 11) in the power supply assembly 30 are disposed in the ports 303A and 303B, respectively. The charging electrode 306 is designed to contact the charged electrode 62 of the power supply assembly 30, and the charging electrode 308 is designed to contact the charged electrode 64 of the power supply assembly 30. For example, the charging electrode 306 is a positive electrode and the charging electrode 308 is a negative electrode, but the charging electrode 306 may be a negative electrode and the charging electrode 308 may be a positive electrode. Each port is provided with two upper charging electrodes 306 and two lower charging electrodes 308. Even if one charging electrode 306 and one charging electrode 308 fail, power is supplied to the other charging electrodes. The device can be charged. However, a single upper charging electrode 306 and a single lower charging electrode 308 may be provided at each port.

  The upper charging electrode 306 and the lower charging electrode 308 of each port are provided in one charger that charges one power supply assembly 30. The charger corresponding to the first port 303A is called a first charger 305A, and the charger corresponding to the second port 303B is called a second charger 305B. The four first chargers 305A charge the power supply assembly 30 when the power supply assembly 30 is held in the first port 303A. The four second chargers 305B charge the power supply assembly 30 when the power supply assembly 30 is held in the second port 303B.

  As best shown in FIG. 30, the upper charging electrode 306 in each port is attached to the upper electrode support 307, and the lower charging electrode 308 in each port is connected to the lower electrode support 307. Is attached. Left and right power supply assembly lock levers 310 and 312 for locking the power supply assembly 30 at the port 303A or 303B are attached to each of the electrode supports 307. A cavity is provided between the upper power supply assembly lock levers 310 and 312 and the lower power supply assembly lock levers 310 and 312. The cavity is a window 309 into which the power assembly fixing portion 206 enters when the power assembly replacement mechanism 200 moves forward as described above.

  Details of the power supply assembly lock levers 310 and 312 will be described with reference to FIGS. 31 and 32. The power supply assembly lock levers 310 and 312 are substantially L-shaped and can be rotated about the rotation shafts 318 and 320, respectively. A claw 310A is formed at the front end of the arm extending forward of the power supply assembly lock lever 310, and a protrusion 314 is fixed to the other arm extending in the lateral direction. A claw 312A is formed at the front end of one arm of the power supply assembly lock lever 312, and a projection 316 is fixed to the other arm. These power supply assembly lock levers 310 and 312 are arranged in line symmetry.

  A spring 311 is disposed between the arm extending forward of the power supply assembly lock levers 310 and 312 and the wall 304 adjacent thereto. The spring 311 gives the power assembly lock levers 310 and 312 a force for bringing the claws 310A and 312A closer to each other. Accordingly, as shown in FIG. 31, the claws 310A and 312A are caught by the cover panel 58 of the power supply assembly 30, whereby the power supply assembly 30 is locked to the power supply assembly lock levers 310 and 312 and moves in the port 303A or 303B. It is held without. In the state shown in FIG. 31, the charging electrode 306 contacts the charged electrode 62 of the power supply assembly 30, the charging electrode 308 contacts the charged electrode 64 of the power supply assembly 30, and the charger is connected to the power supply device 60 in the power supply assembly 30. To charge.

  On the other hand, a long plate 248 is fixed to the bar 204 and the power supply assembly fixing portion 206 of the power supply assembly replacement mechanism 200. A groove 249 extending in the longitudinal direction is formed at the center of the long plate 248. The groove 249 has a wide width defined at both ends 250 at the front end and a narrow width defined at both ends 252 in the rear portion.

  When the bar 204 is advanced together with the power supply assembly fixing portion 206 from the state shown in FIG. 31, first, the protrusions 314 and 316 are received in the wide front end portion (defined by both ends 250) of the groove 249. Next, as shown in FIG. 32, the protrusions 314, 316 are received in the narrow width rear portion of the groove 249 (defined by the ends 252), which causes the power assembly lock levers 310, 312 to move to the spring 311. The claws 310A and 312A are rotated so as to be separated from each other. In other words, the power supply assembly lock levers 310 and 312 are unlocked, and the power supply assembly 30 can move away from the port 303A or 303B. Thus, when the power supply assembly 30 is removed from the power supply assembly lock levers 310 and 312, the magnetic force of the power supply assembly fixing portion 206 is made effective so that the power supply assembly 30 does not fall off the charging device 5.

  FIGS. 31 and 32 show the upper power supply assembly lock levers 310 and 312 and the long plate 248 for operating them. Although not shown in detail, a long plate similar to the long plate 248 is fixed to the lower surface of the bar 204 and the power supply assembly fixing portion 206, and this long plate operates the lower power supply assembly lock levers 310 and 312. .

  When the power supply assembly 30 enters the ports 303A and 303B, the cover panel 58 of the power supply assembly 30 pushes the claws 310A and 312A of the power supply assembly lock levers 310 and 312 to widen the distance therebetween. As a result, as shown in FIG. 31, the claws 310 </ b> A and 312 </ b> A are hooked on the cover panel 58 of the power supply assembly 30, whereby the power supply assembly 30 is locked to the power supply assembly lock levers 310 and 312.

  The power supply assembly holder 300 is supported so as to be movable laterally with respect to the main base 140. By the lateral movement of the power supply assembly holder 300 in which the first port 303A and the second port 303B are arranged, each of the bars 204 of the power supply assembly changing mechanism 200 causes the corresponding power supply assembly fixing portion 206 to be connected to the power supply assembly fixing portion 206. Through the window 309, it is possible to enter one of the first ports 303A and one of the second ports 303B. According to this configuration, the plurality of first ports 303A and the plurality of second ports 303B are moved in the lateral direction so that the power supply assembly attached to the bar is fixed while the traveling device 10 is stopped at a fixed position. The first power supply assembly 30 can be attached to and detached from the traveling device 10 through the first port 303A, and the same power supply assembly fixing part 206 passes through the second port 303B. 30 can be attached to and detached from the traveling device 10. In this manner, each bar and each power supply assembly fixing portion is used for mounting and removing both the first power supply assembly 30 and the second power supply assembly 30. Therefore, the number of parts can be reduced as compared with the case where the first power supply assembly bar and the power supply assembly fixing portion and the second power supply assembly bar and the power supply assembly fixing portion are provided.

  As shown in FIGS. 18 and 22, a holder motor 170 (lateral movement mechanism) is attached to the bottom wall 141 of the main base 140, and a rotor 172 is attached to the rotation shaft of the holder motor 170. ing. Although not shown, the base frame 302 of the power supply assembly holder 300 has a portion that meshes with the rotor 172. When the rotating shaft of the holder motor 170 rotates, the rotor 172 rotates and the entire power supply assembly holder 300 moves in the lateral direction with respect to the main base 140.

  As shown in FIG. 22, the main base 140 includes four roller sets 146 (traveling device locking mechanism) for locking the traveling device 10. Each roller set 146 includes a movable roller 148 (first roller) rotatably supported by a lever 152 and a fixed roller 150 (second roller) rotatably supported by a fixed roller stage 154. .

  Details of the roller set 146 will be described with reference to FIGS. 33 to 35. As shown in FIGS. 33 and 34, the lever 152 that supports the movable roller 148 can rotate around the central axis 190. A movable roller 148 is rotatably attached to one end of the lever 152, and a first bent piece 192 is formed at the other end. Also, in the vicinity of the movable roller 148, a second bent piece 194 is formed at one end of the lever 152, and the second bent piece 194 is pushed by a spring 196, and the lever 152 has A clockwise force is always applied.

  On the other hand, a protrusion 326 is fixed to the power supply assembly holder 300. In FIG. 33, the solid line indicates a state where the power supply assembly holder 300 is in the left limit position with respect to the main base 140. Lever 152, movable roller 148 and protrusion 326 shown in phantom lines are the angular position of lever 152 when power supply assembly holder 300 is to the right of the left limit position and to the left of the right limit position, and movable roller 148. And the position of the protrusion 326.

  Since the force of the spring 196 is applied to the lever 152, when the power supply assembly holder 300 is on the right side of the left limit position and on the left side of the right limit position, the movable roller 148 is on the left side as indicated by a virtual line. In the position. For this reason, in one roller set 146, the distance between the movable roller 148 and the fixed roller 150 is narrow, and the traveling device 10 can be sandwiched between them. Thus, each roller set 146 includes the rollers 148 and 150 that sandwich the plurality of traveling devices 10.

  Preferably, the movable roller 148 rotates only in the clockwise direction of FIG. 33, and the fixed roller 150 rotates only in the counterclockwise direction of FIG. Accordingly, the rollers 148 and 150 rotate when the traveling device 10 moves in the direction toward the power supply assembly holder 300 (the direction in which the bar moves backward), and the direction in which the traveling device 10 moves away from the power supply assembly holder 300 (the direction in which the bar advances). ) Is not rotated when moving. Such one-way operation is achieved, for example, by providing one-way bearings or one-way clutches on the rollers 148 and 150. Since the rollers 148 and 150 are only allowed to rotate in one direction, the power assembly fixing portion 206 moves forward to approach the power assembly 30 and push the power assembly 30 in order to remove the power assembly 30 from the traveling device 10. Even if it does, the traveling apparatus 10 does not advance carelessly.

  When the power supply assembly holder 300 moves from the right position with respect to the main base 140 (protrusion 326 is indicated by a virtual line in FIG. 33) to the left limit position (solid line state in FIG. 33), the protrusion 326 is moved. The first bent piece 192 is pushed toward the left, and the lever 152 is rotated counterclockwise. As a result, the movable roller 148 moves to the right position as indicated by the solid line. For this reason, in one roller set 146, the space | interval of the movable roller 148 and the fixed roller 150 spreads, and the traveling apparatus 10 can be released among these.

  As shown in FIGS. 33 to 35, one side of an L-shaped plate 328 is fixed to the power supply assembly holder 300. A protrusion 330 is formed on the arm 329 which is the other piece of the plate 328.

  In FIG. 35, the solid line indicates a state where the power supply assembly holder 300 is in the right limit position with respect to the main base 140. Lever 152 and movable roller 148 shown in phantom lines indicate the angular position of lever 152 and the position of movable roller 148 when power supply assembly holder 300 is to the left of the right limit position and to the right of the left limit position. .

  Since the force of the spring 196 is applied to the lever 152, when the power supply assembly holder 300 is on the left side of the right limit position and on the right side of the left limit position, the movable roller 148 is on the left side as indicated by a virtual line. In the position. For this reason, in one roller set 146, the space | interval of the movable roller 148 and the fixed roller 150 is narrow, and the traveling apparatus 10 can be pinched | interposed between these.

  When the power supply assembly holder 300 moves from the left position to the right limit position (solid line state in FIG. 35) with respect to the main base 140, the protrusion 330 of the plate 328 is directed to the right, and the second bent piece 194 is directed to the right. To rotate the lever 152 counterclockwise. As a result, the movable roller 148 moves to the right position as indicated by the solid line. For this reason, in one roller set 146, the space | interval of the movable roller 148 and the fixed roller 150 spreads, and the traveling apparatus 10 can be released among these.

  Thus, the traveling device locking mechanism using the roller set 146 is used when the power supply assembly 30 is attached to and detached from the traveling device 10 and when the other power supply assemblies 30 are attached to and removed from the plurality of traveling devices 10. Each of the traveling devices 10 is locked. According to this configuration, since the traveling device lock mechanism locks the traveling device 10, the traveling device 10 is stabilized when the power supply assembly 30 is attached to and detached from the traveling device 10.

  In addition, this travel device locking mechanism is configured so that when the holder motor 170 which is a lateral movement mechanism moves the plurality of first ports 303A and the plurality of second ports 303B in the lateral direction, the ports 303A and 303B In conjunction, the plurality of traveling devices 10 are locked and released. Thus, since the traveling device lock mechanism is interlocked with the ports 303A and 303B, a dedicated drive source for the traveling device lock mechanism is not required.

  As shown in FIG. 22, sensors 180, 182, 184, 186 for determining the lateral position of the power supply assembly holder 300 are attached to the bottom wall 141 of the main base 140. Although not shown, a plurality of detection pieces to be detected by the sensors 180, 182, 184, and 186 are fixed to the power supply assembly holder 300. Each of these sensors 180, 182, 184, 186 is, for example, a photo interrupter.

  When the power supply assembly holder 300 reaches the right limit position (position in FIG. 35), the detected piece reaches the sensor 180 and is detected. The detection of the detected piece by the sensor 180 is referred to as the sensor 180 being turned on. The ON signal of the sensor 180 indicates that the power supply assembly holder 300 is in the right limit position and thus the roller set 146 is unlocked. That is, the sensor 180 is a right limit position detection sensor of the power supply assembly holder.

  When the power supply assembly holder 300 reaches the left limit position (position in FIG. 33), the detected piece reaches the sensor 186 and is detected. The detection of the detected piece by the sensor 186 is referred to as the sensor 186 being turned on. The ON signal of the sensor 186 indicates that the power supply assembly holder 300 is in the left limit position, and thus the roller set 146 is unlocked. That is, the sensor 186 is a left limit position detection sensor of the power supply assembly holder.

  On the other hand, the ON signal output from the sensor 182 when the sensor 182 detects the detected piece indicates that the power supply assembly 30 can be replaced at the second port 303B of the power supply assembly holder 300. That is, as shown in FIGS. 45 to 47, the power supply assembly fixing portion 206 can access the second port 303B through the window 309 (FIG. 30). That is, the sensor 182 is a replaceable detection sensor at the second port.

  The ON signal output from the sensor 184 when the sensor 184 detects the detected piece indicates that the power supply assembly 30 can be replaced at the first port 303A of the power supply assembly holder 300. That is, as shown in FIGS. 16, 17, 19, and 20, the power supply assembly fixing portion 206 can access the first port 303 </ b> A through the window 309 (FIG. 30). That is, the sensor 184 is a replaceable detection sensor at the first port.

  36 to 38, the power supply assembly exchanging mechanism 200 can remove the power supply assembly 30 from the plurality of traveling devices 10 and charge the power supply device 60 of the power supply assembly 30 with the first charger 305A. The power supply assembly 30 is moved to the first port 303A. Thereafter, the power supply assembly replacement mechanism 200 moves the second power supply assembly 30 charged with the power supply device 60 by the second charger 305B so as to be attached to the traveling device 10 from the second port 303B.

  For convenience, the power supply device 60 charged by the first charger 305A at the first port 303A is referred to as the first power supply device 60. The power supply assembly 30 that incorporates the first power supply device 60 and is attached to the first port 303A is referred to as the first power supply assembly 30.

  The power supply device 60 that is charged by the second charger 305B at the second port 303B is referred to as a second power supply device 60 for convenience. The power supply assembly 30 that incorporates the second power supply device 60 and is attached to the second port 303B is referred to as a second power supply assembly 30.

  Before the operation shown in FIGS. 36 to 38, charging device 5 is in the state shown in FIGS. This state is a standby state in which the first port 303A is empty and the second power supply assembly 30 is held in the second port 303B. In this state, the base plate 202 of the power supply assembly replacement mechanism 200 is retracted to the rear limit position. In addition, since the power supply assembly holder 300 is in the right limit position (solid line in FIG. 35), the interval between the movable roller 148 and the fixed roller 150 is increased in the roller set 146 as described above. That is, the traveling device lock mechanism is in the released state. Further, the magnetic force of the power supply assembly fixing portion 206 is disabled.

  Also, one or more plays of the horse racing game are completed before the operations shown in FIGS. In those plays, the traveling device 10 is equipped with the first power supply assembly 30 and is powered by the first power supply assembly 30 and travels. On the other hand, the second charger 305B completes the charging of the power supply device 60 of the second power supply assembly 30 held in the second port 303B.

  36 to 38, first, the overall control device 100 transmits a travel control signal for guiding the travel device 10 to move to the power supply assembly replacement position in front of the first port 303A of the charging device 5. To do. The travel device 10 is powered by the first power supply assembly 30 and travels. When traveling device 10 arrives at the power supply assembly replacement position shown in FIGS. 41 and 42 (step S1), overall control device 100 stops both wheel motors 28 of traveling device 10 (step S2).

  Next, the overall control apparatus 100 starts rotating the holder motor 170 that moves the power supply assembly holder 300 in the lateral direction (step S3). The power supply assembly holder 300 starts to move to the left from the position shown in FIGS. With this movement, when the power supply assembly fixing portion 206 of the power supply assembly changing mechanism 200 reaches a position where the first port 303A can be accessed through the window 309 (FIG. 30), the overall control apparatus 100 is connected to the first port 303A. An ON signal is received from the replaceable detection sensor 184 (FIG. 22) (step S4). Then, overall control apparatus 100 stops the rotation of holder motor 170, and power supply assembly holder 300 stops at the position shown in FIGS. 41 and 42 (step S5). In this state, as described above with reference to FIG. 35, the distance between the movable roller 148 and the fixed roller 150 is narrow, and the traveling device 10 is locked therebetween.

  Next, the overall control apparatus 100 starts rotation of the crank motor 208 that switches the magnetic force of the power supply assembly fixing portion 206 (step S6). The crank 217 moves forward, and the magnetic force of the power supply assembly fixing portion 206 is made effective. As shown in FIG. 43, when the effective magnetic force detection sensor 224 for the power supply assembly fixing portion detects the detected piece 222, the overall control apparatus 100 receives an ON signal from the sensor 224 (step S7). Then, the overall control apparatus 100 stops the rotation of the crank motor 208 (step S8).

  Next, the overall control apparatus 100 starts rotation of the replacement mechanism motor 149A that moves the power supply assembly replacement mechanism 200 back and forth (step S9). When power supply assembly replacement mechanism 200 moves forward and front limit position detection sensor 156 for the power supply assembly replacement mechanism detects detected piece 240, overall control device 100 receives an ON signal from sensor 156 (step S10). Then, the overall control apparatus 100 stops the rotation of the replacement mechanism motor 149A (step S11). In this state, as shown in FIG. 43, the bar 204 passes through the first port 303A, and the power assembly fixing portion 206 at the tip of the bar 204 accesses the first power supply assembly 30 held by the traveling device 10.

The power assembly 30 secured to 206 is held at the port for charging. Then, the overall control apparatus 100 stops the rotation of the replacement mechanism motor 149A (step S14).

  Next, the overall control apparatus 100 starts rotation of the crank motor 208 that switches the magnetic force of the power supply assembly fixing portion 206 (step S15). The crank 217 is retracted, and the magnetic force of the power supply assembly fixing portion 206 is invalidated. When the magnetic force invalid detection sensor 225 for the power supply assembly fixing portion detects the detected piece 222, the overall control apparatus 100 receives an ON signal from the sensor 225 (step S16). Then, the overall control apparatus 100 stops the rotation of the crank motor 208 (step S17).

  Next, the overall control apparatus 100 starts rotation of the replacement mechanism motor 149A that moves the power supply assembly replacement mechanism 200 back and forth (step S18). When power supply assembly replacement mechanism 200 moves backward and rear limit position detection sensor 160 for the power supply assembly replacement mechanism detects detected piece 242, overall control device 100 receives an ON signal from sensor 160 (step S 19). Then, the overall control apparatus 100 stops the rotation of the replacement mechanism motor 149A (step S20).

An ON signal is received from the exchangeable detection sensor 182 (FIG. 22) (step S22). Then, overall control apparatus 100 stops the rotation of holder motor 170, and power supply assembly holder 300 stops at the position shown in FIGS. 45 and 46 (step S23).

  Next, the overall control apparatus 100 starts rotating the crank motor 208 that switches the magnetic force of the power supply assembly fixing portion 206 (step S24). The crank 217 moves forward, and the magnetic force of the power supply assembly fixing portion 206 is made effective. As shown in FIG. 47, when the magnetic force effective detection sensor 224 for the power supply assembly fixing portion detects the detected piece 222, the overall control apparatus 100 receives an ON signal from the sensor 224 (step S25). Then, the overall control apparatus 100 stops the rotation of the crank motor 208 (step S26 in FIG. 38).

  Next, the overall control apparatus 100 starts rotation of the replacement mechanism motor 149A that moves the power supply assembly replacement mechanism 200 back and forth (step S27). The power supply assembly changing mechanism 200 moves forward. In this state, as shown in FIG. 47, the bar 204 passes through the second port 303B. As described above with reference to FIGS. 31 and 32, as the bar 204 moves forward, the lock to the second power supply assembly 30 by the power supply assembly lock levers 310 and 312 is released. The magnetic force of the power supply assembly fixing portion 206 at the tip of the bar 204 is effective, and the power supply assembly fixing portion 206 is fixed to the second power supply assembly 30 to remove the second power supply assembly 30 from the second port 303B and move. It is attached to the traveling device 10 that is locked by a roller 148 and a fixed roller 150. In this way, the second power supply assembly 30 charged by the second charger 305B at the second port 303B is attached to the traveling device 10. When the front limit position detection sensor 156 for the power supply assembly replacement mechanism detects the detected piece 240 by the advance of the power supply assembly replacement mechanism 200, the overall control apparatus 100 receives an ON signal from the sensor 156 (step S28). Then, the overall control apparatus 100 stops the rotation of the replacement mechanism motor 149A (step S29).

  Next, the overall control apparatus 100 starts rotation of the crank motor 208 that switches the magnetic force of the power supply assembly fixing portion 206 (step S30). As shown in FIG. 48, the crank 217 is retracted, and the magnetic force of the power supply assembly fixing portion 206 is invalidated. When the magnetic force invalid detection sensor 225 for the power supply assembly fixing portion detects the detected piece 222, the overall control device 100 receives an ON signal from the sensor 225 (step S31). Then, the overall control apparatus 100 stops the rotation of the crank motor 208 (step S32).

The power supply assembly holder 300 starts to move to the left from the position shown in FIG. Along with this movement, the overall control apparatus 100 receives an ON signal from the left limit position detection sensor 186 (FIG. 22) of the power supply assembly holder (step S37). Then, overall control apparatus 100 stops the rotation of holder motor 170, and power supply assembly holder 300 stops at the position shown in FIGS. 49 and 50 (step S38). Since the power supply assembly holder 300 is in the left limit position (solid line in FIG. 33), as described above, in the roller set 146, the distance between the movable roller 148 and the fixed roller 150 is increased. That is, the traveling device lock mechanism is in the released state.
