However, the first monitoring device 850 (object motion storage device) needs to be stored using a counter circuit or a CPU, and there is a problem that the circuit configuration becomes complicated.
In order to simplify the circuit configuration, it is conceivable to use a current direction storage means having a simple configuration in place of the counter circuit or the CPU. However, if the door is opened and then closed again, that is, if the state of the object is returned to the original state, the memory state of the current direction storage means will also return to the original state, and it will not be understood that there was an action of the object. There was a problem.

  The present invention solves the above-described problems, and in the object motion storage device using the electromotive force generation means and the current direction storage means, the motion of the object is detected even if the operated object is returned to the original state.

  According to the first aspect of the present invention, by providing the rectifying means, the current flowing backward in the first direction does not flow in the current direction storage means. In other words, even if an electric current in the direction opposite to that when the operated object is returned to its original state and operated in the detection coil flows, the current flows only in the first direction in the current direction storage means. The state of the direction storage means will not return to the original state. Therefore, in the object motion storage device using the electromotive force generation means and the current direction storage means, it is possible to reliably store the fact that the object has moved even if the operated object is returned to the original state.

[First Embodiment]
The object motion storage device 100 according to the first embodiment will be described below.

  First, the configuration of the object motion storage device 100 according to the present embodiment will be described with reference to FIGS. FIG. 1 is a circuit diagram showing a configuration of an object motion storage device 100 according to the first embodiment. 2 is a schematic cross-sectional view showing an example of the structure of the electromotive force generating means 11, FIG. 2 (a) is a schematic cross-sectional view showing the state of the electromotive force generating means 11 when not operated, and FIG. It is a schematic cross section which shows the state of the electromotive force generation means 11 at the time. FIG. 3 is a diagram showing details of the current direction storage means 13. FIG. 4 is a schematic diagram showing a usage example when the object motion storage device 100 according to the first embodiment is used in a gaming machine.

  As shown in FIG. 1, the object motion storage device 100 includes a control circuit 30 in which an electromotive force generation means 11, a current direction storage means 13, a load 14, a rectification means 25, and an internal reset circuit 28 are connected in parallel. For example, it is possible to detect and store the presence / absence of an operation of an object OB such as a door of a gaming machine.

  First, the electromotive force generating means 11 will be briefly described. The electromotive force generating means 11 includes a detection magnet 11a and a detection coil 11b. The detection magnet 11a and the detection coil 11b are arranged so as to be relatively movable, and the detection coil 11b is arranged in the magnetic field of the detection magnet 11a. When the detection magnet 11a moves relative to the detection coil 11b, the magnetic field applied to the detection coil 11b changes, and an induced electromotive force is generated, so that a current flows through the detection coil 11b. For example, as shown in FIG. 2, the electromotive force generating means 11 includes a detection magnet 11a, a detection coil 11b, an urging member 11c, an operation member 11d, and a case 11e. 11 d of operation members have the main-body part 11f, and the operation knob 11g protrudes from the main-body part 11f. The detection magnet 11a is held by the main body 11f of the operation member 11d. The case 11e is hollow and has a space in which the operation member 11d, the detection coil 11b, and the biasing member 11c can be accommodated. The case 11e is provided with a through-hole through which the operation knob 11g can be inserted, and the inside and the outside of the case 11e are connected via the through-hole. Inside the case 11e, the detection coil 11b is fixed so as to be electrically connectable to the outside, and the operation member 11d is disposed so as to be movable along the detection coil 11b by inserting the operation knob 11g through the through hole. Has been. At this time, the detection magnet 11a faces the detection coil 11b and is spaced apart from the detection coil 11b. The urging member 11c is disposed between the main body portion 11f of the operation member 11d and the inner wall of the case 11e, and urges the operation member 11d. The urging member 11c abuts on the back side of the surface on which the operation knob 11g is provided, and urges the operation member 11d together with the detection magnet 11a in the direction having the through hole. When the electromotive force generating means 11 configured in this manner is not operated, the operating member 11d is biased toward the through hole as shown in FIG. Further, as shown in FIG. 2B, the electromotive force generating means 11 detects when the operation knob 11g is pressed by an object OB (for example, a door) against the urging force of the urging member 11c. It moves along the coil 11b. That is, when the operation knob 11g is pressed in conjunction with the operation of the object OB, the detection magnet 11a moves along the detection coil 11b. Thus, when the detection magnet 11a moves along the detection coil 11b, an induced electromotive force is generated in the detection coil 11b, and a current flows. That is, electric power can be generated. In addition, if the press of the operation knob 11g is cancelled | released, it will return to the state before operation. Moreover, you may use the state which pressed the operation knob 11g as an initial state.

  The current direction storage means 13 is connected to the wiring 12, the ground circuit 13a, the first circuit 13b, and the second circuit 13c. When a current in the first direction D1 flows through the wiring 12, the ground circuit 13a and the second circuit 13c are brought into conduction, and this state is maintained even when there is no current flowing through the wiring 12. When a current in the second direction D2 flows through the wiring 12, the ground circuit 13a and the first circuit 13b become conductive, and this state is maintained even when there is no current flowing through the wiring 12.

  In the present embodiment, the load 14 is an LED (Light Emitting Diode). The load 14 may be a fixed resistor instead of the LED.

  The rectifying means 25 is a diode of an electronic component having a current rectifying action.

  The internal reset circuit 28 is provided in parallel to the rectifier 25 and includes a reset rectifier 26 and a reset switch 27. The reset rectifier 26 and the reset switch 27 are provided in series. Is formed. The reset rectifier 26 is a diode.

  Next, details of the current direction storage means 13 will be described with reference to FIG. The current direction storage means 13 includes a C-shaped ferrite core 50, a coil portion 12 a that is a part of the wiring 12 and wound around the ferrite core 50, and a magnetic field direction sensing disposed in a gap portion of the ferrite core 50. An element 51 is included. The ferrite core 50 is made of a magnetic material. When a current in the D1 direction flows through the wiring 12, the ferrite core 50 is magnetized so that the end 50a becomes the N pole and the end 50b becomes the S pole, and the current flowing through the wiring 12 disappears. Also, the magnetized state is maintained. Further, when a current in the direction D2 flows through the wiring 12, the end portion 50a is magnetized so as to become the S pole and the end portion 50b becomes the N pole, and the magnetized state is maintained even when the current flowing through the wiring 12 disappears. . When the end 50a is N pole and the end 50b is S pole, the magnetic field direction sensing element 51 connects the ground circuit 13a and the second circuit 13c, and the end 50a becomes S pole and the end 50b. When N becomes the N pole, the ground circuit 13a and the first circuit 13b are connected. From which of the first circuit 13b and the second circuit 13c the current flows, it is possible to know in which direction the current flows in the wiring 12.

  Next, the structure (wiring) of the object motion storage device 100 will be described with reference to FIG. The detection coil 11b of the electromotive force generating means 11 is housed in the electromotive force generating means 11 so that it can be electrically connected to the outside. As shown in FIG. 1, the wiring 12 has one end and the other end connected in series to one end and the other end of the detection coil 11b. Thus, by operating the electromotive force generating means 11, when an induced electromotive force is generated in the detection coil 11 b and a current flows, a current also flows in the wiring 12. Further, a load 14 is connected in series and a power supply VCC is connected to the first circuit 13b and the second circuit 13c connected in parallel to the current direction storage means 13, respectively. Further, the circuit that is electrically connected to the first circuit 13b and the second circuit 13c is a ground circuit 13a. The rectifying means 25 is provided between the detection coil 11b and the wiring 12, and is connected to the wiring 12 in a direction in which current flows only in the first direction D1. The internal reset circuit 28 is connected in parallel with the rectifier 25. The reset rectifying means 26 is connected in such a direction that current flows only in the second direction D2, which is opposite to the first direction D1, and the internal reset circuit 28 is non-conductive when the reset switch 27 is not operated. It has become.

Next, the operation of the object motion storage device 100 will be described with reference to FIG. In the state before the electromotive force generating means 11 is operated, the ground circuit 13a is assumed to be in conduction with the first circuit 13b. Further, when a current flows through the wiring 12 in the first direction D1 shown in FIG. 1, the ground circuit 13a and the first circuit 13b are switched from the conductive state to the ground circuit 13a and the second circuit 13c. It is assumed that it is set to switch. When the operation member 11d (see FIG. 2) of the electromotive force generating means 11 is operated, an induced electromotive force is generated in the detection coil 11b, and a current flows in the first direction D1. The current flows through the control circuit 30 connected in series to the detection coil 11b, but flows through the circuit on the side where the rectifying means 25 connected in the direction in which the current flows only in the first direction D1. A current also flows through the wiring 12 connected to the detection coil 11b via the control circuit 30. When a current flows in the first direction D1, the ferrite core 50 and the magnetic field direction sensing element 51 operate corresponding to the direction of the current, and the ground circuit 13a and the first circuit 13b are brought into conduction from the ground circuit 13a. And the second circuit 13c are switched to a conductive state, and this state is maintained. Even if the door DR is closed and the electromotive force generating means 11 is operated in the reverse direction, the current in the second direction D2 is blocked by the rectifying means 25 and does not flow. Therefore, even if the state of the door DR is returned to the original state, the storage state of the current direction storage means 13 is not returned to the original state, and it can be reliably stored that the door DR has been opened. .

  Hereinafter, in order to prevent illegal acts on the gaming machine, the case where the object motion storage device 100 is used for the purpose of storing whether the gaming machine door is opened or closed at night (out of business hours) will be described with reference to FIGS. Complement. As shown in FIG. 4, the object motion storage device 100 is attached to the main body of the gaming machine DP, and the operation knob 11g of the operating member 11d is placed on the door DR of the gaming machine DP at a position pressed when the door DR is closed. It is arranged so that it protrudes toward. When used in this application, the electromotive force generating means 11 is in the initial state when the operating member 11d is pressed by the object OB as shown in FIG. That is, in FIG. YY, the state in which the door DR is closed and the operation member 11d is pressed by the door DR (object OB) is the initial state. By setting the current to flow in the first direction D1 shown in FIG. 1 when the door DR is opened and the pressing of the operation member 11d is released, the game machine DP is transferred to the gaming machine DP at night (outside business hours). Even if there is no power supply, the presence or absence of the opening operation of the door DR can be stored. Further, the light emission color of the load 14 (LED) arranged in the first circuit 13b and the second circuit 13c is a different color. For example, the light emission color of the load 14 arranged in the first circuit 13b is blue, and the second circuit The light emission color of the load 14 arranged at 13c is red. When business hours are reached and power is supplied to the gaming machine DP, when the door DR is not opened or closed, the load 14 (blue) arranged in the first circuit 13b emits light, and the door DR is opened. In this case, the load 14 (red) arranged in the second circuit 13c emits light.

  Hereinafter, a method of resetting the current direction storage means 13 to return to the initial state in which the ground circuit 13a and the first circuit 13b are conducted will be described. Press and hold the reset switch 27 attached to the side surface of the game machine DP. If the door DR is closed, the door DR is once opened and then closed again. If the door DR is opened, the door DR is closed as it is. When the door is closed, the electromotive force generating means 11 is operated in the reverse direction, and a current in the second direction D2 flows through the reset rectifying means 26 and the reset switch 27. The current returns to the initial state in which the ground circuit 13a and the first circuit 13b are conducted by the current in the second direction D2.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

  It has a detection magnet 11a and a detection coil 11b that can relatively reciprocate in conjunction with the reciprocation of the object OB, and generates a current in the first direction D1 according to the forward movement of the object OB and also the object OB. The electromotive force generation means 11 for generating a current in the second direction D2 opposite to the first direction D1 in response to the reverse operation of the current, and the current generated by the electromotive force generation means 11 connected to the electromotive force generation means 11 Current direction storage means 13 for detecting and storing the current direction, and provided between the detection coil 11b and the current direction storage means 13 so that a current flows through the current direction storage means 13 only in the first direction D1. The rectifying means 25 is provided.

  Thereby, since it starts with the electric power which the electromotive force generation means 11 generate | occur | produced, a battery is unnecessary. In addition, since the current direction storage means 13 is used, it can be understood that the object OB has operated by examining the states of the ferrite core 50 and the magnetic field direction sensing element 51. Further, if the state of the ferrite core 50 and the magnetic field direction sensing element 51 is examined, it can be seen that the object OB has been operated. Therefore, a count circuit, a CPU, and the like are unnecessary, and a simple circuit configuration is obtained. Further, by providing the rectifying means 25, no current flowing backward in the first direction D1 flows through the current direction storage means 13. That is, even when the operated object OB is returned to its original state and a current in the direction opposite to that when it is operated in the detection coil 11b flows, the current flows in the current direction storage means 13 only in the first direction D1. Therefore, the state of the current direction storage means 13 does not return to the original state. Therefore, in the object motion storage device 100 using the electromotive force generating means 11 and the current direction storage means 13, it is possible to reliably store the fact that the motion of the object OB has been performed even if the operated object OB is returned to the original state. There is an effect that can be.

  In the object motion storage device 100 according to the first embodiment, the load 14 is an LED, and the light emission colors of the loads 14 arranged in the first circuit 13b and the second circuit 13c are different colors.

  Thereby, the presence / absence of the operation of the object OB (whether the door DR is opened / closed) can be easily determined visually. Further, since the emission color is different between when the object OB is operated and when the object OB is not operated, there is an effect that the identification is easier than in the case where the emission color is the same.

[Second Embodiment]
The object motion storage device 200 according to the second embodiment will be described below with reference to FIG. FIG. 5 is a circuit diagram showing a configuration of the object motion storage device 200 according to the second embodiment.

  The object motion storage device 200 is configured by replacing the internal reset circuit 28 of the object motion storage device 100 in the first embodiment with an external reset circuit 38. In the following description, the same components as those of the object motion storage device 100 in the first embodiment and the object motion storage device 200 in the second embodiment are denoted by the same names and the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 5, the object motion storage device 200 includes an electromotive force generation means 11, wiring 12, current direction storage means 13, load 14, rectification means 25, and external reset circuit 38. Yes. The electromotive force generation means 11, the wiring 12, the current direction storage means 13, the load 14, and the rectification means 25 are the same components as those of the object motion storage device 100 in the first embodiment, and thus detailed description thereof is omitted.

  The external reset circuit 38 includes an external rectifier 36 that is a diode, and a reset control unit CU that can flow a current to the external rectifier 36 and can control a current to flow to the external rectifier 36. The external rectifier 36 and the reset control unit CU are connected in series. Note that the current flowing from the reset control unit CU has such a magnitude that the magnetization direction of the ferrite core 50 of the current direction storage unit 13 can be changed when the wiring 12 flows in the second direction D2. In this embodiment, the reset control unit CU is a component of the external reset circuit 38, but may be a component such as a gaming machine to which the object motion storage device 200 is attached.

  Next, the structure (wiring) of the object motion storage device 200 will be described with reference to FIG. In the object motion storage device 200, the rectifier 25 is provided between the detection coil 11b and the wiring 12, similarly to the object motion storage device 100 of the first embodiment shown in FIG. When the electromotive force generating means 11 is operated from the initial state, it is assumed that a current flows through the wiring 12 in the first direction D1 due to the induced electromotive force, and the rectifying means 25 flows only a current in the first direction D1. It is arranged in the direction. The external reset circuit 38 is connected to the wiring 12 in parallel. That is, it is connected to both ends of the wiring 12 so as to be in parallel with the electromotive force generating means 11 and the rectifying means 25 connected in series. The external rectifier 36 is disposed in the wiring 12 in a direction in which a current can flow in a second direction D2 that is opposite to the first direction D1.

  Next, the operation of the object motion storage device 200 will be described with reference to FIG. It is assumed that the ground circuit 13a and the first circuit 13b are conductive before the electromotive force generating means 11 is operated. When the current flows in the wiring 12 in the first direction D1 shown in FIG. 1, the ground circuit 13a and the second circuit 13c are connected from the state in which the ground circuit 13a and the first circuit 13b are connected. Assume that it is set to switch to a state. When the operation member 11d (see FIG. 2) of the electromotive force generating means 11 is operated, an induced electromotive force is generated in the detection coil 11b, and the rectifying means 25 causes a current flowing in the first direction D1 to flow. The wiring 12 flows in the first direction D1. Corresponding to the direction of the current flowing in the wiring 12 when the current flows in the first direction D1, the ground circuit 13a and the second circuit 13c are conductive from the state in which the ground circuit 13a and the first circuit 13b are conductive. Switched to the held state and held.

  The object motion storage device 200 can pass a current from the external reset circuit 38 (reset control unit CU) to the wiring 12. In addition, the external rectifier 36 of the external reset circuit 38 allows only a current flowing in the second direction D2. That is, the reset control unit CU can flow only the current flowing in the second direction D2 through the wiring 12. Note that the current flowing from the reset control unit CU has such a magnitude that the magnetization direction of the ferrite core 50 of the current direction storage unit 13 can be changed when the wiring 12 flows in the second direction D2. Therefore, the current direction storage unit 13 can be reset (returned to the initial state) by flowing a current from the reset control unit CU to the wiring 12 in the second direction D2.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

  The object motion storage device 200 according to the present embodiment includes a pair of wirings connected in parallel to the wiring 12 and capable of flowing a current through the wiring 12 in a second direction D2 opposite to the first direction D1. An external reset circuit 38 is provided.

  As a result, when a current in the reverse direction (second direction D2) is caused to flow through the wiring 12 via the external reset circuit 38, a current in a direction to return the magnetization direction of the ferrite core 50 to the initial state flows through the wiring 12. The direction storage means 13 can be reset. That is, there is an effect that the state of the current direction storage unit 13 can be returned to the state before the object OB is operated.

  As described above, the object motion storage device according to the embodiment of the present invention has been specifically described. However, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. Is possible. For example, the present invention can be modified as follows, and these embodiments also belong to the technical scope of the present invention.

Also good. For example, it may be used for storage of whether or not the door of a medicine storage is opened or closed. Moreover, it is not limited to the memory of whether or not some kind of door is opened or closed.

  (2) In the second embodiment, the reset control unit CU is configured to flow the current in the wiring 12 in the second direction D2 using the power supplied to the gaming machine DP, but the same as the electromotive force generation means 11 A structure using electromotive force generating means having a structure may be used.
