Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Among the components appearing, those having the same function are given the same reference numerals, and the description thereof is omitted.
Fig. 1 is a diagram showing an example of a game system according to an embodiment of the present invention. The game system of the present invention includes an apparatus control device 10, dollies 20a, 20b, a controller 17, and a cassette 18.
The dollies 20a, 20b are mobile devices capable of autonomous travel, and both have the same function. Hereinafter, these carriages 20a, 20b are referred to as carriages 20 unless particularly required to be distinguished. The carriage 20 has a position detection camera on its lower surface, and controls the movement of the carriages 20a and 20b based on the detected position. The equipment control device 10 controls the cart 20 via wireless. The controller 17 is an input device for acquiring an operation performed by a user, and is connected to the device control apparatus 10 via a cable.
The device control apparatus 10 includes a recess 32 in which the cart 20 is placed for charging, and a power supply terminal. A power cord 19 is connected to the power supply terminal, and the power cord 19 is connected to an AC adapter not shown. The device control apparatus 10 has a structure for inserting and extracting a cartridge 18 in which software and the like are stored.
Fig. 2 is a perspective view showing an example of the shapes of the clip 18 and the connector 34. The connector 34 is built in the device control apparatus 10. The clip 18 has a structure to be fitted to the connector 34. Fig. 3 is a plan view showing an example of the internal configuration of the cassette 18. The clip 18 has a housing formed of an outer member 41 and an inner member 42, and a base plate 44 fixed in the housing. A nonvolatile memory 46 and electrostatic protection elements 47 and 48 are disposed above the substrate 44.
The structure of the substrate 44 will be further described. Fig. 4 is a plan view showing an example of substrate 44 in cassette 18. The substrate 44 is made of an insulating resin. The substrate 44 has a substantially rectangular shape in plan view. When the clip 18 is inserted into the connector 34, one side (hereinafter, referred to as "fitting end") of the substrate 44 is fitted into the connector 34. A plurality of connection terminals P are arranged along the fitting end of the substrate 44 near the fitting end. The fitting end of the substrate 44 and the plurality of connection terminals P are exposed from the housing. The plurality of connection terminals P are patterned electrodes formed on the substrate 44, and are exposed from the insulating layer on the substrate 44. When the card tape 18 is inserted into the connector 34, each connection terminal P is electrically connected to a metal part in the connector 34. The memory arrangement region 51 is a region on the substrate 44 in which the nonvolatile memory 46 is arranged.
Fig. 5 is a diagram illustrating the arrangement of the connection terminals P included in the cartridge 18. The plurality of connection terminals P includes, in order from the left side of fig. 4, signal terminals P1, P2, a ground terminal P3, a clock terminal P4, a detection terminal P5, a power supply voltage terminal P6, a ground terminal P7, and signal terminals P8 to P12. The signal terminals P1, P2, P8 to P10 are terminals to which signals for communicating with the nonvolatile memory 46 are supplied. The nonvolatile memory 46 supplies a signal indicating whether or not the device control apparatus 10 is an access target to the signal terminal P8. The nonvolatile memory 46 exchanges data with the device control apparatus 10 using the signal terminals P1, P2, P9, and P10 when a specific signal is supplied from the signal terminal P8. The signal terminals P11 and P12 are extension terminals. When an expansion integrated circuit is mounted on the cartridge 18, the integrated circuit and the device control apparatus 10 communicate with each other via the signal terminals P11 and P12.
A potential of 3.3V is supplied as a power supply potential to the power supply voltage terminal P6. A potential of 0V is supplied as a ground potential to the ground terminals P3, P7. The power supply voltage terminal P6 and the ground terminals P3 and P7 are electrically connected to terminals of the nonvolatile memory 46, respectively.
The power supply voltage terminal P6 and the ground terminal P7 are sandwiched between signal terminals P1, P2, and P8 to P12. When the direction from the ground terminal P7 toward the power supply voltage terminal P6 in the arrangement direction of the connection terminals P is taken as a first direction and the opposite direction is taken as a second direction, more specifically, the signal terminals P1, P2 are disposed on the first direction side (left side) of the power supply voltage terminal P6 and the signal terminals P8 to P12 are disposed on the second direction (right side) side of the ground terminal P7.
In the substrate 44 shown in fig. 4, the power supply voltage terminal P6 and the ground terminal P7 are arranged substantially at the center in the region where the power connection terminals P are arranged. More specifically, the number of signal terminals disposed between the power supply voltage terminal P6 and the ground terminal P7 (0 in the example of fig. 4) is smaller than the number of signal terminals disposed on the first direction side of the power supply voltage terminal P6 (3 in the example of fig. 4 where the clock terminal P4 is also a kind of signal terminal), and is smaller than the number of a plurality of signal terminals disposed on the second direction side (right side) of the ground terminal P2 (5 in the example of fig. 4). If the above conditions are satisfied, a signal terminal may be provided between the power supply voltage terminal P6 and the ground terminal P7.
The power supply voltage terminal P6 and the ground terminal P7 are arranged in the vicinity of the memory arrangement region 51. More specifically, the power supply voltage terminal P6 and the ground terminal P7 are disposed between the fitting end of the substrate 44 and the nonvolatile memory 46 in a plan view.
The detection terminal P5 is an electrode for detecting the insertion and removal of the cartridge 18. The detection terminal P5 is electrically connected to the ground terminals P3 and P7 on the substrate 44, and the potential of the detection terminal P5 is the ground potential in a state where the card 18 is inserted into the connector 34. The device control apparatus 10 detects the insertion and removal of the cartridge 18 based on the change in the electrical characteristics caused by the electrical connection between the detection terminal P5 and the electrode of the connector 34.
The clock terminal P4 is supplied with a clock for operating the nonvolatile memory 46 from the device control apparatus 10. The clock terminal P4 is sandwiched by connection terminals P (specifically, a ground terminal P3, a detection terminal P5, and a power supply voltage terminal P6) to which a power supply voltage or a ground voltage is supplied. The clock terminal P4 is adjacent to the ground terminal P3 and the detection terminal P5, which are connection terminals P to which a power supply voltage or a ground voltage is supplied.
The power supply voltage terminal P6 and the ground terminal P7 are adjacent to each other and disposed at the center, so that the loop size due to the power supply path TH through which the power supply current flows is minimized, thereby suppressing the generation of electromagnetic waves due to variations in the power supply current. This can suppress electromagnetic waves emitted from the cassette 18.
In addition, since the clock terminal P4 to which the clock is supplied is adjacent to the connection terminal P to which the power supply voltage or the ground voltage is supplied, the clock terminal P4 is sandwiched by the low impedance wiring. This also suppresses emission of electromagnetic waves by the clock. Further, the detection terminal P5 also serves as the low-impedance wiring, whereby the connection terminal P can be efficiently arranged.
Fig. 6 is a plan view illustrating the arrangement of the connection terminals P in the cassette 18. The power supply voltage terminal P6 and the ground terminal P7 are disposed closer to the mating end than the signal terminals P1, P2, and P8 to P12. In other words, the interval C1 between the power supply voltage terminal P6 and the ground terminal P7 and the fitting end is smaller than the interval C2 between the signal terminals P1, P2, P8 to P12 and the fitting end.
The detection terminal P5 is disposed farther from the mating end than the signal terminals P1, P2, P8 to P12. In other words, the distance C3 between the detection terminal P5 and the engagement end is larger than the distance C2 between the signal terminals P1, P2, P8 to P12 and the engagement end.
When L is the distance between the connection terminal P (signal terminal P12) and the detection terminal P5, which are distant from the detection terminal P5, among the connection terminals P (signal terminals P1 and P12) disposed at the end portions, the distance S by which the detection terminal P5 is retreated is greater than k times L (for example, k is 0.05) than the signal terminals P1, P2, and P8 to P12. Distance S is the value of separation C3 minus separation C2. In addition, the constant k is determined according to the existing play between the cartridge 18 and the connector 34. More specifically, the constant k may be calculated based on the maximum angle at which the chuck 18 is obliquely inserted through the play.
The power supply voltage terminal P6 and the ground terminal P7 are disposed closer to the mating terminal than the signal terminals P1, P2, P8 to P12, whereby the nonvolatile memory 46 can be activated more stably. The detection terminal P5 is arranged farther from the mating end than the other connection terminals P, particularly P1, P2, P9, and P10, and thus insertion is detected after all connections to terminals necessary for access to the circuit side in the substrate 44, such as the nonvolatile memory 46, are completed. This enables the nonvolatile memory 46 and the like disposed in the substrate 44 to operate more stably.
Note that the cassette 18 is not necessarily a cassette that stores only software. Instead of the nonvolatile memory 46, some integrated circuits may be housed.
