Description

  Embodiments described herein relate generally to a charging device for a biological information measurement device, a biological information measurement system, and a biological information measurement device.

  Conventionally, biological information such as an electrocardiogram, a pulse wave, and an electroencephalogram must be sent to a hospital for measurement. However, with the recent development of electronic devices, development of portable biological information measuring devices that can easily measure such biological information is progressing.

  Such a portable biological information measuring device often has a battery as its power source. By using a battery as a power source, it is possible to measure in a state where the measurement subject is floating from the ground, that is, in an insulated state, in the measurement of obtaining biological information by contacting the electrode with the measurement subject such as an electrocardiogram It becomes.

  Therefore, without providing various safety mechanisms for avoiding electric shock to the measurement subject due to a poor insulation of the power supply system, which is indispensable for a biological information measuring device that obtains power from a commercial power supply, safety is ensured. It can be secured. Furthermore, by omitting these safety mechanisms, it greatly contributes to the reduction in size and weight that is important in portable biological information measuring devices.

  As the battery, a rechargeable secondary battery is often used. In order to charge the secondary battery, it is common to supply commercial power to the biological information measuring device via the charging device. In the case of such a charging method, if the biological information measuring device is used at the time of charging, there is a possibility that an electric shock or the like may be given to the measurement subject if an insulation failure or the like occurs in the charging device.

  Hereinafter, embodiments will be specifically described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a schematic configuration of a biological information measuring system 100 according to the first embodiment. The biological information measuring system 100 includes a biological information measuring device 1 (hereinafter simply referred to as a measuring device 1) and a charging device 2 for the measuring device 1 (hereinafter simply referred to as a charging device 2). In the present embodiment, it is assumed that the measuring apparatus 1 is portable. By using the secondary battery 11, the measuring device 1 can measure biological information without receiving external power supply. The charging device 2 charges the secondary battery 11 of the measuring device 1 with an external power source. Hereinafter, the configuration of the measuring device 1 and the charging device 2 will be described in detail.

  The measuring device 1 includes a secondary battery 11, a measuring electrode 12, a measuring circuit (measuring means) 13, and a power receiving terminal 14.

  The secondary battery 11 is a storage battery that is charged by the charging device 2 and is, for example, a lithium ion battery. The secondary battery 11 supplies power to the measurement circuit 13 and operates it.

  The measurement electrode 12 is formed of a conductive material such as a metal, and is in contact with a human body, more specifically, a measurement site of a measurement subject during measurement. The measurement electrode 12 is an electrocardiogram electrode, a myoelectric potential electrode, or the like, and detects data necessary for measuring biological information from the measurement site. In addition, there is no restriction | limiting in particular in the number of the measurement electrodes 12, What is necessary is just to provide the number of measurement electrodes 12 required for the measurement of biological information.

  The measurement circuit 13 is operated by power from the secondary battery 11. The measurement circuit 13 is connected to the measurement electrode 12 and measures biological information based on data detected by the measurement electrode 12. The biological information is, for example, an electrocardiogram, a pulse wave, an electroencephalogram or the like.

  The power receiving terminal 14 is connected to the measurement circuit 13. The power receiving terminal 14 is connected to the power feeding terminal 22 of the charging device 2 when the secondary battery 11 is charged. When the power feeding terminal 22 is connected, the power receiving terminal 14 receives power (voltage) from the charging device 2 and supplies it to the secondary battery 11 via the measurement circuit 13.

  On the other hand, the charging device 2 includes a voltage converter 21, a power feeding terminal 22, and a covering member 23.

  The voltage converter 21 converts an external power supply voltage into a voltage suitable for charging the secondary battery 11. For example, a commercial 100V AC voltage is connected to the charging device 2 as an external power source, and the voltage converter 21 converts this 100V AC voltage into a 5V DC voltage.

  The power feeding terminal 22 is connected to the voltage converter 21. The power feeding terminal 22 is connected to the power receiving terminal 14 of the measuring apparatus 1 when the secondary battery 11 is charged. As a result, the voltage output from the voltage converter 21 is supplied to the secondary battery 11 via the power supply terminal 22, the power receiving terminal 14 and the measurement circuit 13, whereby the secondary battery 11 is charged.

  Here, in the unlikely event that an insulation failure occurs in the charging device 2 due to a failure or the like, when the power feeding terminal 22 and the power receiving terminal 14 are connected, an abnormal voltage derived from an external power supply voltage is applied to the measurement electrode 12. There is no possibility of it occurring. If the measurement subject touches the measurement electrode 12 in this state, the measurement subject may be shocked by the voltage. In particular, when the measuring apparatus 1 is an electrocardiographic measuring apparatus, if the measurement subject applies the measuring electrode 12 to the chest near the heart, a serious accident may occur.

  Therefore, in the present embodiment, the charging device 2 is provided with a covering member 23 formed of an insulating material such as a resin so that the measurement electrode 12 does not touch the measurement subject during charging. The cover member 23 covers the measurement electrode 12 when the power supply terminal 22 is connected to the power reception terminal 14 and charging is performed. This improves the safety of the biological information measurement system. More specific description will be given below.

  2A and 2B are a top view and a bottom view of the measuring apparatus 1, respectively. FIG.2 (c) is a side view of the measuring apparatus 1 seen from the arrow A direction of Fig.2 (a), (b). As shown in the figure, the upper surface and the lower surface of the housing 10 of the measuring apparatus 1 are substantially rectangular and rounded at the corners. A secondary battery 11 and a measurement circuit 13 are arranged inside the housing 10 (not shown).

  Then, as shown in FIGS. 2A and 2C, four power receiving terminals 14 are provided along one short side of the housing 10 on the upper surface of the housing 10 of the measuring apparatus 1 and exposed. Yes. Also, as shown in FIGS. 2B and 2C, two measurement electrodes 12a and 12b are provided on the lower surface of the housing 10 of the measuring apparatus 1 in the vicinity of each short side of the housing 10 so as to be exposed. doing. The arrangement of the power receiving terminal 14 and the measurement electrode 12 is not particularly limited. For example, the distance from the power receiving terminal 14 to the short side may be equal to the distance from one measurement electrode 12b to the short side.

  Note that in FIG. 2C, the power receiving terminal 14 is drawn thick for the sake of clarity, but actually it is desirable that the power receiving terminal 14 be thinner, and it may be substantially flush with the top surface of the housing 10, and a recess is formed on the top surface. The power receiving terminal 14 may be provided inside the recess.

  3A and 3B are side views of the charging device 2 according to the first embodiment (a closed state and an open state, respectively), and FIG. 3C is a bottom view thereof. As shown in FIGS. 3A and 3B, the charging device 2 has a shape similar to a clothespin, and includes a covering member 23, a fixing member 24, a hinge (rotating member) 25, and a knob portion 26a. , 26b.

  A cover member 23 extending from the hinge 25 to one side and a knob portion 26a extending to the other side are integrally formed. As shown in FIG. 3C, the covering member 23 has two claws 23a and 23b corresponding to the measurement electrodes 12a and 12b, respectively. During charging, the covering member 23 presses the lower surface of the measuring device 1. More specifically, the cover member 23 covers the measurement electrode 12a with the claw 23a and covers the measurement electrode 12b with the claw 23b.

  The shape of the covering member 23 is not limited to the shape shown in FIG. 3C, and may be a flat surface that covers all the measurement electrodes 12a and 12b, for example.

  A fixing member 24 extending from the hinge 25 to one side and a knob portion 26b extending to the other side are integrally formed. A power supply terminal 22 is provided on the fixing member 24. During charging, the fixing member 24 presses the upper surface of the measuring device 1. At this time, the power supply terminal 22 is provided on the fixing member 24 at a position corresponding to the power reception terminal 14 so that the power supply terminal 22 is connected to the power reception terminal 14.

  The shape of the fixing member 24 is not particularly limited. For example, the measuring device 1 can be provided in a well-balanced manner by providing two claws as in the case of the covering member 23 or by forming a flat surface that covers the entire top surface of the housing 10. It is desirable to be able to fix it. Although not shown, the power converter 22 is connected to the voltage converter 21 shown in FIG.

  The covering member 23 and the fixing member 24 are connected to each other via a hinge 25 so as to be rotatable. When no force is applied to the knob portions 26a and 26b from the outside, the charging device 2 is closed (FIG. 3A) by the force of a spring (not shown) built in the hinge 25. More specifically, the space between the covering member 23 and the fixing member 24 is in a state smaller than the measuring apparatus 1 or the end of the covering member 23 and the end of the fixing member 24 are in contact with each other.

  When external force is applied to the knob portions 26a and 26b against the spring, the charging device 2 is in an open state (FIG. 3B). That is, the distal end of the fixing member 24 rotates upward about the hinge 25, so that a space is created between the covering member 23 and the fixing member 24. More specifically, a larger space than the measuring apparatus 1 is formed between the covering member 23 and the fixing member 24.

  When charging the measuring device 1, a sufficient force is applied to the knob portions 26 a and 26 b with a finger so that the charging device 2 is opened. And the measuring apparatus 1 is arrange | positioned in the space of FIG.3 (b) created between the covering member 23 and the fixing member 24. FIG. At this time, the measuring device 1 is aligned so that the measuring electrodes 12a and 12b of the measuring device 1 are covered with the claws 23a and 23b of the covering member 23, respectively. Thereafter, the force applied to the knob portions 26 a and 26 b is relaxed to close the charging device 2, and the measuring device 1 is sandwiched between the covering member 23 and the fixing member 24. Then, the measuring device 1 is fixed by the covering member 23 and the fixing member 24 by the force of the spring. Thereby, the power supply terminal 22 provided in the fixing member 24 contacts the power receiving terminal 14 of the measuring apparatus 1 and charging is started.

  FIG. 4 is a side view of the measuring device 1 and the charging device 2 during charging. As illustrated, when the measuring device 1 is arranged on the charging device 2, the power supply terminal 22 of the charging device 2 is connected to the power receiving terminal 14 of the measuring device 1, and the covering member 23 of the charging device 2 is connected to the measuring device 1. The measurement electrode 12 is covered.

  Thus, in the first embodiment, the measurement electrode 12 is covered with the electrode covering member 23 during charging. Therefore, it becomes difficult for a measurement subject to touch the measurement electrode 12, and the safety of the biological information measurement system can be improved. Further, the voltage converter 21 need not have a safety mechanism, and the cost can be reduced.

  Furthermore, since a safety mechanism is not required, the voltage converter 21 can even be omitted. For example, when the secondary battery 11 can be directly charged by a DC voltage from a USB (Universal Serial Bus), a voltage converter in a charger of a personal computer or a mobile phone (smart phone) can be used. Thereby, the cheap and lightweight charging device 2 which uses the cover member 23 and the fixing member 24 as main members is realizable.

(Second Embodiment)
In the second embodiment described below, charging is performed in a state in which the measurement electrode 12 is more reliably covered with the covering member 23.

  FIG. 5 is a block diagram showing a schematic configuration of the biological information measuring system 100a according to the second embodiment. Portions common to FIG. 1 are denoted by the same reference numerals, and the differences will be mainly described below.

  The charging device 2a in the present embodiment includes a switch (first switch) 27. When the switch 27 is turned on (first state), the switch 27 connects the voltage converter 21 and the power supply terminal 22, and supplies the voltage from the voltage converter 21 to the power supply terminal 22. On the other hand, the switch 27 does not connect the voltage converter 21 and the power feeding terminal 22 in the off state (second state), and does not supply the voltage from the voltage converter 21 to the power feeding terminal 22.

  In addition, the charging device 2 a includes switch control means (second switch) 28. The switch control means 28 detects that the measuring device 1 is accommodated in the charging device 2a and the charging device 2a is completely closed, and sets the switch 27 to ON. That is, the switch control unit 28 sets the switch 27 to be on in response to the covering member 23 covering the measurement electrode 12. On the other hand, when the covering member 23 does not cover the measurement electrode 12, the switch control means 28 sets the switch 27 to OFF.

  Since the switch 27 and the switch control means 28 are provided, the voltage from the voltage converter 21 is supplied from the power supply terminal 22 to the power reception terminal 14 only after the cover electrode 23 covers the measurement electrode 12, thereby charging the secondary battery 11. Can be done. In other words, when the cover electrode 23 does not cover the measurement electrode 12, external power is not supplied to the power receiving terminal 14, and the secondary battery 11 is not charged. Therefore, when the cover electrode 23 does not cover the measurement electrode 12, even if an insulation failure or the like occurs in the charging device 2a, an abnormal voltage derived from the external power source does not occur in the measurement electrode 12. . As a result, safety can be further improved.

Hereinafter, some specific examples of the charging device 2a will be described.
FIG. 6 is a side view of a first example of the measuring apparatus 1 and the charging apparatus 2a during charging. This charging device 2 a has a mechanical switch as the switch 27. More specifically, a push rod 281 as the switch control means 28 extends downward from the tip of the fixing member 24. The push rod 281 may be integrated with the fixing member 24 or may be a separate member. On the other hand, a hole slightly larger than the push rod 231 is formed at the tip of the covering member 23, and a push rod receiver 271 as a switch 27 is provided inside the hole.

  When the charging device 2 a is completely closed and the covering member 23 covers the measurement electrode 12, the push rod 281 pushes the push rod receiver 271. As a result, the switch 27 is turned on. As a result, the voltage from the voltage converter 21 is applied to the power supply terminal 22 and charging starts.

  On the other hand, when the charging device 2a is open or incompletely closed, the push rod 281 does not push the push rod receiver 271. As a result, the switch 27 is turned off. As a result, the voltage from the voltage converter 21 is not applied to the power supply terminal 22 and charging is not performed.

  In this way, charging is performed only when the charging device 2a is completely closed and the covering member 23 reliably covers the measurement electrode 12. In other words, when there is a possibility that the covering member 23 does not cover the measurement electrode 12, no voltage is applied to the power supply terminal 22. Thereby, the safety | security of a biometric information measurement system can be improved. In particular, when the switch 27 is turned off, the voltage converter 21 and the power supply terminal 22 are mechanically and electrically separated from each other.

  In addition, when there are a plurality of wires (for example, a ground wire and a voltage wire) from the voltage converter 21 to the power supply terminal 22, a switch 27 may be provided in a part of the wires. It is desirable to provide a switch 27 in the wiring.

  FIG. 7 is a side view of a second example of the measuring device 1 and the charging device 2a during charging. The charging device 2 a has a magnetic switch as the switch 27. More specifically, a magnet 282 as a switch control means 28 is provided inside the tip of the fixing member 24. On the other hand, a Hall element as a switch 27 or a reed switch 272 is provided inside the front end of the covering member 23. The operating principle is the same as in FIG. 6, and the switch 27 is turned on when the charging device 2 a is completely closed and the covering member 23 covers the measurement electrode 12.

  6 and 7 are merely examples, and the switch 27 and the switch control means are detected by using other means for detecting that the covering member 23 has covered the measurement electrode 12 and connecting the voltage converter 21 and the power supply terminal 22. 28 may be configured.

  Thus, in 2nd Embodiment, the switch 27 and the switch control means 28 are provided in the charging device 2a. Then, it is detected that the covering member 23 has covered the measurement electrode 12, and the switch 27 is turned on. Thereby, since charging is performed in a state where the covering member 23 reliably covers the measurement electrode 12, the safety of the biological information measurement system can be further improved.

(Third embodiment)
In the second embodiment described above, the switch 27 is provided in the charging device 2a. On the other hand, in the third embodiment described below, a switch is provided in the measuring apparatus.

  FIG. 8 is a block diagram showing a schematic configuration of a biological information measuring system 100b according to the third embodiment. Portions common to those in FIG. 5 are denoted by the same reference numerals, and the differences will be mainly described below.

  The measuring apparatus 1a in the present embodiment includes a switch (second switch) 15. When the switch 15 is turned on (first state), the switch 15 is disconnected without connecting the measurement electrode 12 and the measurement circuit 13. As a result, the measurement electrode 12 becomes floating. On the other hand, the switch 15 connects the measurement electrode 12 and the measurement circuit 13 in the off state (second state). Thereby, the measuring apparatus 1a becomes a state which can measure biometric information.

  In addition, the charging device 2 b includes a switch control unit (second switch control unit) 28. The switch control means 28 detects that the measuring device 1a is accommodated in the charging device 2b and the charging device 2b is completely closed, and sets the switch 15 to ON. That is, the switch control unit 28 sets the switch 15 to ON in response to the covering member 23 covering the measurement electrode 12. On the other hand, when the covering member 23 does not cover the measurement electrode 12, the switch control means 28 sets the switch 15 to OFF.

  Since the switch 15 and the switch control means 28 are provided, when the cover member 23 covers the measurement electrode 12, charging is started and the measurement electrode 12 and the measurement circuit 13 are shut off. Therefore, the conduction from the measurement circuit 13 to the measurement electrode 12 is interrupted simultaneously with the start of charging or before the start of charging. Therefore, even if an insulation failure occurs in the charging device 2b, an abnormal voltage derived from the external power source is not generated in the measurement electrode 12 during charging. As a result, safety can be further improved.

Hereinafter, some specific examples of the measuring device 1a and the charging device 2b will be described.
FIG. 9 is a top view of a first example of the measuring apparatus 1a. This measuring device 1 a has a mechanical switch as the switch 15. More specifically, a through hole 151 is formed in the upper surface of the housing 10. A push rod receiver 152 as a switch 15 is provided in the back of the through hole 151.

  FIG. 10 is a side view of a first example of the measuring device 1a and the charging device 2b during charging. In the figure, the power receiving terminal 14 and the power feeding terminal 22 are not shown. In the fixing member 24 in the charging device 2b, a push rod 283 as the switch control means 28 extends downward from the fixing member 24 at a position corresponding to the through hole 151 of the measuring device 1a.

  When the charging device 2b is completely closed and the cover member 23 covers the measurement electrode 12, charging is started, and the push rod 283 enters the through hole 151 of the measurement device 1a and pushes the push rod receiver 152 at the back thereof. As a result, the switch 15 is turned on, and the measurement electrode 12 and the measurement circuit 13 are disconnected.

  On the other hand, when charging is not performed, the switch 15 is turned off, the measurement electrode 12 and the measurement circuit 13 are connected, and biological information can be measured.

  Thus, since the measurement electrode 12 and the measurement circuit 13 are interrupted while charging is performed, safety can be improved. In particular, when the switch 15 is turned off, the measurement electrode 12 and the measurement circuit 13 are mechanically and electrically separated from each other.

  In addition, when there are a plurality of measurement electrodes 12, a switch 15 may be provided in a part of them, but it is desirable to provide a switch 15 corresponding to all the measurement electrodes 12 for completeness.

  FIG. 11 is a side view of a second example of the measuring device 1a and the charging device 2b during charging. This measuring device 1 a has a magnetic switch as the switch 15. More specifically, a magnet 284 as the switch control means 28 is provided at a predetermined position inside the fixing member 24. On the other hand, a Hall element or a reed switch 153 as a switch 15 is provided in a position corresponding to the magnet 284 inside the housing 10 of the measuring apparatus 1a. The operating principle is the same as in FIG. 10, and the switch 15 is turned on when charging is started.

  Thus, in 3rd Embodiment, the switch 15 is provided in the measuring apparatus 1a and the switch control means 28 is provided in the charging device 2b. When the cover member 23 covers the measurement electrode 12 and performs charging, the switch 15 is turned on. Thereby, since the measurement electrode 12 and the measurement circuit 13 are interrupted during charging, the safety of the biological information measurement system can be further improved.

(Fourth embodiment)
FIGS. 12A and 12B are side views (a closed state and an open state, respectively) of the charging apparatus 2c according to the fourth embodiment. FIG. 13 is a perspective view of the charging device 2c.

  As shown in FIGS. 12A and 12B, in the charging device 2c of this embodiment, a cover member 23 extending upward from the base point 23a and a knob portion 26 extending downward from the base point 23a are integrally formed. Yes. The covering member 23 and the knob portion 26 are connected to the container 30 so as to be rotatable by a hinge (rotating member) 29. The voltage converter 21 of FIG. 1 is connected to a terminal 31 provided in the container 30 via, for example, a USB cable.

  As shown in FIG. 13, the fixing member 24 is disposed inside the container 30. A hole 32 is formed in the fixing member 24. As will be described later, the power supply terminal 22 is provided at the back of the hole 32 in a state where charging is not performed, that is, in a state where the charging device 2c is opened or the measuring device 1 is not disposed. In this way, the power supply terminal 22 is not exposed on the surface of the charging device 2c during non-charging, so that it is difficult to touch the power supply terminal 22.

  FIG. 14 is a diagram illustrating the inside of the charging device 2c with the container 30 made transparent in FIG. 12 (b). As shown, a foot opening spring 33 is provided between the lower portion of the fixing member 24 and the knob portion 26. When no force is applied to the knob part 26, the foot opening spring 33 pushes out the knob part 26, so that the charging device 2c is closed (FIG. 12A). More specifically, the space between the covering member 23 and the fixing member 24 is smaller than the measuring device 1.

  On the other hand, when a force is applied to the knob portion 26 against the foot opening spring 33, the covering member 23 and the knob portion 26 rotate about the hinge 29, whereby the charging device 2c is in an open state (FIG. 12). (B), FIG. 14). More specifically, a larger space than the measuring apparatus 1 is formed between the covering member 23 and the fixing member 24.

  Further, as shown in FIG. 14, the substrate 34 is fixed to the inner surface of the container 30. The power supply terminal 22 is fixed to the substrate 34. A coil spring 35 is provided between the fixing member 24 and the substrate 34. The coil spring 35 presses the fixing member 24 against the covering member 23 and the knob portion 26 side. Therefore, the distance from the substrate 34 to the surface of the fixing member 24 is longer than the distance from the substrate 34 to the tip of the power supply terminal 22, and the power supply terminal 22 is located at the back of the hole 32 of the fixing member 24.

  When charging the measuring device 1, a sufficient force is applied to the knob portion 26 with a finger so that the charging device 2 c is opened. And the measuring apparatus 1 is arrange | positioned in the space of FIG.12 (b) created between the covering member 23 and the fixing member 24. FIG. Then, the force applied to the knob portion 26 is relaxed, and the charging device 2c is closed. Then, the covering member 23 presses the lower surface of the measuring device 1, and the fixing member 24 presses the upper surface of the measuring device 1. As a result, the measuring device 1 is fixed.

  FIG. 15 is a side view of the measuring device 1 and the charging device 2c at the time of charging, and the container 30 is drawn transparent as in FIG. In this state, the measuring apparatus 1 presses the fixing member 24 against the substrate 34 against the coil spring 35. As a result, the distance from the substrate 34 to the tip of the power supply terminal 22 is longer than the distance from the substrate 34 to the surface of the fixing member 24. Therefore, the power feeding terminal 22 is exposed on the fixing member 24 and contacts the power receiving terminal 14 of the measuring device 1 arranged. Thereby, charging is started.

  Thus, also in 4th Embodiment, since the measurement apparatus 1 is charged in the state which the cover member 23 covered the measurement electrode 12, the safety | security of a biological information measurement system can be improved. Further, in a state where the power supply terminal 22 is not connected to the power receiving terminal 14, the power supply terminal 22 is not exposed on the surface of the charging device 2c. Therefore, the power supply terminal 22 can be prevented from being touched unnecessarily.

(Other embodiments)
Hereinafter, other embodiments will be exemplified.
FIG. 16 is a side view of the measuring device 1 and the charging device 2d during charging. As illustrated, the covering member 23 and the fixing member 24 are rotatably attached via a hinge 25. During charging, the cover member 23 is used as a back cover, and the cover member 23 and the fixing member 24 are fixed by a latch 24 a provided at the tip of the fixing member 24. Thereby, charging can be performed in a state where the covering member 23 covers the measurement electrode 12. In order to make the cover member 23 and the fixing member 24 detachable with the latch 24a, it is desirable to form the fixing member 24 with a flexible resin or the like.

  FIG. 17 is a side view of the measuring device 1 and the charging device 2e during charging. As illustrated, the cover member 23 is plate-shaped. Then, loop surfaces 23p and 23q constituting a detachable surface fastener are attached to the surface of the covering member 23 opposite to the surface that covers the measurement electrode 12. On the other hand, the fixing member 24 is formed of a flexible cloth or the like, and at least both ends of the surface covering the measuring device 1 have hook surfaces 24p and 24q constituting a surface fastener. Alternatively, the entire fixing member 24 may be formed of a hook surface.

  At the time of charging, the measuring device 1 is placed on the plate-like covering member 23. Then, the measuring device 1 is covered with the fixing member 24 so that the loop surface 23p and the hook surface 24p are coupled and the loop surface 23q and the hook surface 24q are coupled. Thereby, charging can be performed in a state where the covering member 23 covers the measurement electrode 12.

  Further, one end of the fixing member 24 may be joined to the covering member 23 in advance so that the covering member 23 and the fixing member 24 do not fall apart.

  FIG. 18A is a perspective view when the charging device 2f is in an open state. FIG. 18B is a side view of the charging device 2f in a closed state. As illustrated, a box-type charging device 2f in which the covering member 23 is a container, the fixing member 24 is a lid, and these are rotatably coupled by a hinge 25 may be used.

  Needless to say, the above-described embodiments may be arbitrarily combined.
