Description

Aspects of the present invention relate generally to a paper wrapper.

Assistance for excretion behavior of a person requiring nursing care is performed in a nursing facility or the like. When assisting the excretion behavior, the caregiver needs to wait outside the toilet space until the excretion of the person requiring care is completed in order to protect the privacy of the person requiring care. At this time, it is difficult for the caregiver to detect the end of excretion, and problems such as the care recipient standing up by himself after excretion and falling may occur. Therefore, there is a demand for a toilet system capable of informing a caregiver that the person requiring care has finished excretion.

As means for realizing such a toilet system, for example, by transmitting information regarding the use of toilet paper, it is conceivable to notify the caregiver of the completion of excretion of the person requiring care. In order to make such notification, for example, it is required to secure electric power for transmitting information in a paper roll holding toilet paper. It is conceivable to secure power by attaching a battery, but there is a risk that information cannot be transmitted if the battery runs out.

Therefore, as in Patent Literature 1, it is conceivable to use the rotation of the toilet paper to generate electricity in the paper winding machine. However, with such a conventional power-generating paper roll, if the amount of toilet paper used (the amount of rotation) is small, the amount of power generated will be small, and there is a problem that the power required to transmit information cannot be secured. On the other hand, if a power generation mechanism that generates a large amount of power at once is used in order to obtain a sufficient amount of power generation even when the amount of toilet paper used is small, a large load will be applied to the toilet paper at once. , There is a problem that the toilet paper is torn.

The transmission determination circuit 30 determines whether or not the power storage unit 20 has enough power to transmit information from the transmission unit 40 to the external device. The transmission determination circuit 30 is electrically connected to the power storage unit 20 and the transmission unit 40 .

The transmission unit 40 transmits information about the use of the paper winding machine 100 to the external device. At this time, the transmission unit 40 transmits information using power generated by the power generation mechanism 10 and stored in the power storage unit 20 . That is, the transmission unit 40 transmits information using power generated by using the paper winding device 100 when the paper winding device 100 is used.

Information about the use of the paper winding machine 100 is information indicating that the paper winding machine 100 has been used. Information about the use of the paper roll 100 is, in other words, information indicating that the toilet paper TP attached to the paper roll 100 has been used. The information about the use of the paper winder 100 is, for example, information indicating that the toilet paper TP has been rotated a predetermined number of times.

The transmitter 40 transmits information to, for example, a receiver located outside the toilet space. The receiving unit is, for example, a mobile phone outside the toilet space, a nurse call system, a personal computer of the administrator, or the like. The receiver may be, for example, a lamp or the like provided outside the toilet space. The transmitter 40 may, for example, transmit information to a receiver outside the toilet space via a gateway provided inside the toilet space.

The transmission unit 40 transmits information at least once using the power stored in the power storage unit 20 while the toilet paper TP rotates once. In other words, the power generation mechanism 10 can generate an amount of electric power sufficient to transmit information at least once while the toilet paper TP rotates once. In other words, power storage unit 20 stores an amount of electric power sufficient to transmit information at least once while toilet paper TP rotates once.

Note that in the embodiment, power is generated two or more times before the toilet paper TP rotates once (for example, in half a revolution), and at this point, enough power is generated to transmit information from the transmission unit 40 to the external device. When electric power is stored in the power storage unit 20, information may be transmitted from the transmission unit 40 before the toilet paper TP rotates once.

3(a) and 3(b) are a front view and a top view schematically showing the paper winding machine according to the embodiment.
As shown in FIGS. 3A and 3B, the paper winding machine 100 according to the embodiment further includes a holding section 50 and a frame 60. As shown in FIGS.

The holding part 50 holds the toilet paper TP. Moreover, the holding part 50 rotates together with the toilet paper TP. The holding portion 50 is connected to the power generation mechanism 10 . Thereby, the holding part 50 can transmit the rotation of the toilet paper TP to the power generation mechanism 10 .

In this example, the holding section 50 has a first holding member 51 and a second holding member 52 . The first holding member 51 is provided on one lateral side (the right side in this example) of the frame 60, and holds one end (the right end in this example) of the toilet paper TP in the lateral direction. . The second holding member 52 is provided on the side surface of the frame 60 on the other side in the left-right direction (the left side in this example), and holds the other end in the left-right direction (the left end in this example) of the toilet paper TP. do.

In this specification, when viewed from the user facing the paper winding device 100 attached to the wall surface, the front side is "front", the back side is "rear", the upper side is "upper", the lower side is "lower", and the left side is "lower". "Left side" and right side are referred to as "right side".

The first holding member 51 and the second holding member 52 are each supported by the frame 60 and provided rotatably with respect to the frame 60 . As a result, the first holding member 51 and the second holding member 52 rotate together with the rotation of the toilet paper TP. The structures of the first holding member 51 and the second holding member 52 will be described later.

In the embodiment, the holding part 50 is not limited to this. For example, the holding part 50 may be provided on either one of the left and right side surfaces of the frame 60 and pass through the core of the toilet paper TP in the left-right direction. .

The frame 60 supports the power generation mechanism 10 and the holding section 50 . In this example, the frame 60 is a U-shaped plate whose front side is open when viewed from above. The power generation mechanism 10 and the holding portion 50 are provided, for example, on the inner side surface of the frame 60 . The power storage unit 20, the transmission determination circuit 30, and the transmission unit 40 may each be attached to the frame 60, or may be attached to a place other than the frame 60, such as the wall surface of the toilet space.

In this example, the frame 60 is attached inside the shell 400 . The shell 400 is, for example, a paper roll originally installed in the toilet space. In this example, the frame 60 is attached while the holding portion 410 provided on the outer shell 400 is folded. In this way, the paper roll 100 according to the embodiment can be attached while leaving the paper roll (outer shell 400) originally installed in the toilet space.

In this example, a paper cutting board 420 is provided above the shell 400 as shown in FIG. 3(a). In this case, the paper cutting board 420 provided on the outer shell 400 can be used as it is. In other words, in this case, there is no need to provide a separate paper cutting board for the frame 60 . Note that FIG. 3B shows a state in which the paper cutting board 420 is omitted.

The frame 60 may be directly attached to the wall of the toilet space where the shell 400 is not provided. In this case, it is preferable to provide a paper cutting board above the frame 60 .

Fig.4 (a) and FIG.4(b) are the side view and sectional drawing which represent typically the paper winding machine which concerns on embodiment.
FIG. 4(a) is a side view seen from the direction of arrow A shown in FIGS. 3(a) and 3(b).
FIG. 4(b) is a cross-sectional view along line B1-B2 shown in FIG. 3(b).
As shown in FIG. 4A , in this example, the power generation mechanism 10 is connected to the first holding member 51 . That is, the power generation mechanism 10 generates power using the rotation of the first holding member 51 that rotates together with the toilet paper TP. The power generation mechanism 10 may be connected to the second holding member 52 or may be connected to both the first holding member 51 and the second holding member 52 . Alternatively, the power generation mechanism 10 connected to the first holding member 51 and the power generation mechanism 10 connected to the second holding member 52 may be provided separately.

As shown in FIG. 4B , the first holding member 51 has a fitting portion 511 , a shaft portion 512 and a restricting portion 513 . The fitting portion 511 fits into the right end of the core of the toilet paper TP. As a result, the fitting portion 511 holds the toilet paper TP and rotates in conjunction with the rotation of the toilet paper TP. The shaft portion 512 is connected to the fitting portion 511 and a part of the power generation mechanism 10 (rotating portion 11 described later). In other words, the fitting portion 511 is connected to the power generating mechanism 10 (rotating portion 11) via the shaft portion 512. As shown in FIG. The restricting portion 513 is provided so as to accommodate a portion of the power generation mechanism 10 (rotating portion 11 ) in the space between the frame 60 and the restricting portion 513 . As a result, the restricting portion 513 restricts the lateral movement of a part (rotating portion 11) of the power generating mechanism 10. As shown in FIG. The shaft portion 512 may be formed integrally with the rotating portion 11 .

5(a) to 5(c) are explanatory diagrams schematically showing the operation of the power generation mechanism of the paper winding machine according to the embodiment.
5(a) to 5(c) show an enlarged view of the power generating mechanism 10 shown in FIG. 4(a).
As shown in FIGS. 4A and 5A to 5C, the power generation mechanism 10 includes, for example, a rotating portion 11, a linear motion conversion portion 12, a power storage portion 13, and a power generation portion. 14 and.

The rotating part 11 rotates in conjunction with the rotation of the toilet paper TP. As shown in FIGS. 4A and 4B, in this example, the rotating portion 11 is connected to the first holding member 51 and rotates in conjunction with the rotation of the first holding member 51. . The rotation axis of the rotating portion 11 is coaxial with the rotation axis of the first holding member 51 . The rotation speed of the rotating part 11 is the same as the rotation speed of the toilet paper TP. In other words, the rotating part 11 rotates once while the toilet paper TP rotates once.

In this example, the rotating portion 11 has a hub 111 and spokes 112 . The hub 111 is positioned at the radial center of the rotating portion 11 . The spokes 112 extend from the hub 111 toward the outside in the radial direction of the rotating portion 11 . In this example, six spokes 112 are provided. The number of spokes 112 may be one or more.

The direct motion converting portion 12 is provided between the rotating portion 11 and the force accumulating portion 13 . The linear motion converting portion 12 converts the rotational motion of the rotating portion 11 into linear motion and transmits the linear motion to the force accumulating portion 13 . That is, the direct-motion converter 12 converts the rotary motion of the toilet paper TP into a linear motion and transmits the linear motion to the force storage unit 13 . The linear motion converter 12 reciprocates along a linear track as the rotating part 11 rotates. A part of the direct-acting converting portion 12 is provided with a tooth 121 that engages with the power generating portion 14 (a gear 141 described later). The direct motion converter 12 is provided as required and can be omitted.

The force storage section 13 stores energy generated by the rotation of the rotating section 11 . That is, the force storage unit 13 stores energy generated by the rotation of the toilet paper TP. In this example, the energy generated by the rotation of the rotating portion 11 is transmitted to the force storage portion 13 via the direct motion conversion portion 12 and stored in the force storage portion 13 . A predetermined amount of energy is stored in the energy storage unit 13 while the rotating unit 11 (toilet paper TP) rotates by a predetermined angle.

The force accumulating portion 13 is, for example, an elastic body such as a spring. More specifically, the force accumulating portion 13 is, for example, a coil spring. In this example, the force accumulating portion 13 is provided so as to be able to expand and contract in the same direction as the direction of the reciprocating motion of the linear motion conversion portion 12 . As will be described later, the force accumulating portion 13 may be a spiral spring.

The power generation unit 14 generates power when the energy stored in the power storage unit 13 exceeds a predetermined amount. The power generation unit 14 generates power using a predetermined amount of energy stored in the power storage unit 13 while the toilet paper TP rotates by a predetermined angle. The power generation unit 14 generates power using, for example, energy released when the power storage unit 13 storing a predetermined amount of energy returns to a steady state. More specifically, the power generation unit 14 utilizes the energy released when the energy storage unit (spring) 13 that stores energy by shrinking returns to its original state (the state before the energy was stored). to generate electricity.

The power generation section 14 has a gear 141 and a motor 142 . The power generation unit 14 generates power by electromagnetic induction. The gear 141 is provided so as to rotate the shaft of the motor 142 in conjunction with the rotation of the gear 141 . The gear 141 is engaged with teeth 121 provided on the direct-acting converter 12 . The gear 141 may have at least teeth with a width that can be engaged with the teeth 121 provided on the linear motion converting portion 12 . That is, the gear 141 may have teeth only partially in the circumferential direction as shown in FIGS. 5A to 5C, or may have teeth all over the circumferential direction. It may be provided.

The operation of the power generating mechanism 10 shown in FIGS. 5(a) to 5(c) will be described below.
When the toilet paper TP rotates, the rotating part 11 rotates in the direction of the arrow in conjunction with it. When the rotating portion 11 rotates, one of the spokes 112 (spoke 112a) of the rotating portion 11 comes into contact with the one end 12a of the direct-acting converting portion 12, as shown in FIG. 5(a).

When the rotating portion 11 rotates further, the direct motion converting portion 12 is pushed by the spokes 112a and moves in the direction of the white arrow, as shown in FIG. 5(b). As a result, the direct motion converter 12 converts the rotary motion of the rotating part 11 into a straight motion. When the direct motion converting portion 12 moves, as shown in FIG. 5B, the force accumulation portion 13 connected to the other end 12b side of the direct motion converting portion 12 is pushed by the direct motion converting portion 12 and contracts. . As a result, the energy generated by the rotation of the rotating portion 11 is transmitted to the force accumulating portion 13 via the linear motion converting portion 12 and is stored. That is, the energy generated by the rotation of the toilet paper TP is stored in the force storage unit 13 .

When the rotating portion 11 rotates further, the spoke 112a in contact with the linear motion converting portion 12 is removed from the one end 12a of the linear motion converting portion 12, as shown in FIG. 5(c). When the spoke 112a is detached from the one end 12a of the linear motion converting portion 12, the rotary motion of the rotating portion 11 is no longer transmitted to the linear motion converting portion 12, and the force accumulating portion 13 attempts to return (stretch) to its original state. As a result, the direct motion converting portion 12 is pushed by the force accumulating portion 13 and moves in the direction of the white arrow. At this time, the direct motion converting portion 12 moves at a speed corresponding to the amount of energy stored in the force storing portion 13 . When the direct motion converting portion 12 moves, the gear 141 of the power generating portion 14 that engages with the teeth 121 of the direct motion converting portion 12 rotates in the direction opposite to that of the rotating portion 11, and the motor 142 of the power generating portion 14 generates power by electromagnetic induction. done. In this manner, the power generation unit 14 is connected to, for example, the direct motion conversion unit 12 and generates power using the motion of the direct motion conversion unit 12 .

When the rotating portion 11 rotates further, another one of the spokes 112 (spoke 112 b ) comes into contact with the one end 12 a of the direct-acting converting portion 12 . By repeating this, power generation in the power generation unit 14 is repeatedly performed. In this example, while the toilet paper TP rotates once, the rotating portion 11 rotates once, and the six spokes 112 provided on the rotating portion 11 generate electricity six times. By changing the number of spokes 112, it is possible to change the number of times of power generation during one revolution of the rotating part 11. FIG.

As shown in FIG. 2, the power generated by the power generation mechanism 10 is stored in the power storage unit 20, for example. Then, in the transmission determination circuit 30, it is determined whether or not the power storage unit 20 has enough power to transmit information from the transmission unit 40 to the external device. When power storage unit 20 stores enough power to transmit information from transmission unit 40 to an external device, power storage unit 20 outputs power to transmission unit 40 . The transmission unit 40 uses power generated by the power generation mechanism 10 and stored in the power storage unit 20 to transmit information on the use of the paper winding device 100 to an external device (reception unit).

In this way, in the power generation mechanism 10, power is generated a plurality of times while the toilet paper TP rotates once, and the generated power is stored in the power storage unit 20, so that the amount of power generated per power generation can be reduced. , sufficient power generation can be secured. As a result, it is possible to prevent the toilet paper TP from running out unintentionally due to the load applied from the power generation mechanism 10 . In addition, the transmission unit 40 transmits the information at least once using the power stored in the power storage unit 20 while the toilet paper TP rotates once, so that the paper roll 100 can be operated even when the amount of toilet paper TP used is small. Information about usage can be securely transmitted to the external device. Therefore, for example, the completion of excretion of the person requiring care can be reliably notified to the caregiver.

Further, according to the paper winding device 100 according to the embodiment, the power generation mechanism 10 is provided with the rotating portion 11 that rotates in conjunction with the rotation of the toilet paper TP, and the rotating portion 11 rotates one time while the toilet paper TP rotates once. By rotating around, it is possible to secure a sufficient amount of power generation with a simple mechanism even when the amount of toilet paper TP used is small.

Further, according to the paper winding machine 100 according to the embodiment, in the power generating mechanism 10, the power storage unit 13 stores energy generated by the rotation of the rotating unit 11, and when the energy stored in the power storage unit 13 exceeds a predetermined amount, power generation is performed. By providing the power generation unit 14 that performs the above, a predetermined amount of energy can be stored in the energy storage unit 13 while the toilet paper TP is rotated by a predetermined angle regardless of the rotation speed of the toilet paper TP. When a predetermined amount of energy is stored in the power storage unit 13, the power generation unit 14 generates power. The power generation amount can be kept substantially constant. That is, even when the rotation speed of the toilet paper TP is low, it is possible to secure a sufficient amount of power generation. As a result, when the paper winding machine 100 is used, information regarding the use of the paper winding machine 100 can be securely transmitted to the external device. Therefore, for example, the completion of excretion of the person requiring care can be reliably notified to the caregiver.

Further, according to the paper winding machine 100 according to the embodiment, the power generation mechanism 10 is provided with the linear motion conversion section 12 that converts the rotary motion of the rotating section 11 into linear motion, and the power generation section 14 is connected to the linear motion conversion section 12. By using the movement of the direct-acting conversion unit 12 to generate power, a sufficient amount of power generation can be ensured with a simple mechanism even when the rotation speed of the toilet paper TP is low.

Further, according to the paper winding device 100 according to the embodiment, the power generation unit 14 has the motor 142 and generates power by electromagnetic induction. Sufficient power generation can be ensured more reliably even when is small.

Fig.6 (a) and FIG.6(b) are sectional drawing and a front view which represent typically the paper winding machine which concerns on embodiment.
FIG. 6(a) is a cross-sectional view taken along line C1-C2 shown in FIG. 3(b).
As shown in FIGS. 6A and 6B , the second holding member 52 has a fitting portion 521 , a shaft portion 522 and a spring 523 .

The fitting portion 521 fits into the left end of the core of the toilet paper TP. As a result, the fitting portion 521 holds the toilet paper TP and rotates in conjunction with the rotation of the toilet paper TP. The shaft portion 522 is connected to the fitting portion 521 and the frame 60 . The fitting portion 521 is provided rotatably with respect to the shaft portion 522 . The fitting portion 521 is provided to be slidable in the left-right direction with respect to the shaft portion 522 , and a spring 523 is provided between the fitting portion 521 and the left side surface of the frame 60 . ing. By pushing the fitting portion 521 in the direction of the arrow in FIG. 6A, the spring 523 is contracted, and the fitting portion 521 can be brought closer to the left side surface of the frame 60 . Thereby, as shown in FIG. 6B, the distance between the first holding member 51 and the second holding member 52 can be increased.

When attaching the toilet paper TP to the paper winding device 100 , first, the left end of the core of the toilet paper TP is fitted into the fitting portion 521 of the second holding member 52 . Next, the fitting portion 521 is moved to the left side by pushing the toilet paper TP to the left side. Thereafter, the right end of the core of the toilet paper TP is fitted into the fitting portion 511 of the first holding member 51, and the fitting portion 521 is released from being pushed. With such a structure, the toilet paper TP can be attached easily.

7(a) to 7(c) are explanatory diagrams schematically showing the operation of a modified example of the power generation mechanism of the paper winding machine according to the embodiment.
As shown in FIGS. 7A to 7C, the power generation mechanism 10A includes a rotating portion 11, a direct motion conversion portion 12, a force storage portion 13, a power generation portion 14, a reduction portion 15, have Since the direct-acting converting portion 12, the power storing portion 13, and the power generating portion 14 are substantially the same as those described above, the description thereof is omitted.

In this example, the rotating portion 11 is not provided with a hub 111 and spokes 112 . The rotating portion 11 is gear-shaped and is engaged with the reduction portion 15 (a gear 153 described later).

The speed reducer 15 has a hub 151 , spokes 152 and gears 153 . The hub 151 is positioned at the radial center of the reduction section 15 . The spokes 152 extend from the hub 151 toward the radially outer side of the reduction section 15 . In this example, six spokes 152 are provided. The number of spokes 152 may be two or more. The rotation axis of hub 151 is coaxial with the rotation axis of gear 153 . Hub 151 rotates in conjunction with rotation of gear 153 . The rotational speed of hub 151 is the same as the rotational speed of gear 153 . That is, the hub 151 rotates once while the gear 153 rotates once.

The gear 153 rotates in conjunction with the rotation of the rotating portion 11 . The diameter of gear 153 is larger than the diameter of rotating part 11 . The rotation speed of gear 153 is lower than the rotation speed of rotating portion 11 . In this example, the gear 153 rotates once while the rotating portion 11 rotates 2.5 times. As a result, the rotating portion 11 can be rotated with a smaller force than the force required to rotate the gear 153 . That is, the force required to pull the toilet paper TP can be reduced. Therefore, it is possible to prevent the toilet paper TP from unintentionally tearing due to the load applied from the power generation mechanism 10, while ensuring a sufficient amount of power generation.

The operation of the power generating mechanism 10A shown in FIGS. 7(a) to 7(c) will be described below.
When the toilet paper TP rotates, the rotating part 11 rotates in the direction of the arrow in conjunction with it. When the rotating part 11 rotates, the gear 153 of the decelerating part 15 rotates in the opposite direction to the rotating part 11 as shown in FIG. 7A. When the gear 153 of the speed reducer 15 rotates, the hub 151 of the speed reducer 15 rotates, and one of the spokes 152 (spoke 152 a ) of the speed reducer 15 abuts the one end 12 a of the linear motion converter 12 .

When the rotating portion 11 rotates further, the linear motion converting portion 12 is pushed by the spokes 152a and moves in the direction of the white arrow, as shown in FIG. 7(b). As a result, the linear motion converting section 12 converts the rotary motion of the rotating section 11 into a linear motion via the deceleration section 15 . When the direct motion converting portion 12 moves, as shown in FIG. 7B, the force accumulation portion 13 connected to the other end 12b side of the direct motion converting portion 12 is pushed by the direct motion converting portion 12 and contracts. . As a result, the energy generated by the rotation of the rotating portion 11 is transmitted to the force storage portion 13 via the deceleration portion 15 and the direct motion conversion portion 12 and stored. That is, the energy generated by the rotation of the toilet paper TP is stored in the force storage unit 13 .

When the rotating portion 11 rotates further, the spokes 152a in contact with the linear motion converting portion 12 are removed from the one end 12a of the linear motion converting portion 12, as shown in FIG. 7(c). When the spoke 152a is detached from the one end 12a of the linear motion converting portion 12, the rotary motion of the rotating portion 11 is no longer transmitted to the linear motion converting portion 12, and the force accumulating portion 13 attempts to return (stretch) to its original state. As a result, the direct motion converting portion 12 is pushed by the force accumulating portion 13 and moves in the direction of the white arrow. At this time, the direct motion converting portion 12 moves at a speed corresponding to the amount of energy stored in the force storing portion 13 . When the direct motion converting portion 12 moves, the gear 141 of the power generating portion 14 that engages with the teeth 121 of the direct motion converting portion 12 rotates in the direction opposite to that of the rotating portion 11, and the motor 142 of the power generating portion 14 generates power by electromagnetic induction. done.

When the rotating portion 11 rotates further, another one of the spokes 152 (spoke 152 b ) comes into contact with the one end 12 a of the direct motion converting portion 12 . By repeating this, power generation in the power generation unit 14 is repeatedly performed. In this example, while the toilet paper TP rotates 2.5 times, the rotating portion 11 rotates 2.5 times and the deceleration portion 15 rotates once. Electric power is generated six times by the six spokes 152 provided on the deceleration section 15 while the deceleration section 15 rotates once. That is, electricity is generated 2.4 times while the toilet paper TP rotates once. By changing the number of spokes 152, it is possible to change the number of power generations during one revolution of the rotating part 11. FIG.

8(a) to 8(d) are explanatory diagrams schematically showing the operation of a modified example of the power generation mechanism of the paper winding machine according to the embodiment.
As shown in FIGS. 8A to 8D, the power generation mechanism 10B has a rotating portion 11, a power storage portion 13, and a power generation portion . In the power generation mechanism 10B, the direct-acting converter 12 is omitted.

In this example, the rotating portion 11 is not provided with a hub 111 and spokes 112 . The rotating part 11 is gear-shaped with teeth 113 , and the teeth 113 are engaged with the gear 141 of the power generation part 14 . In this example, teeth 113 are provided at two locations. It is sufficient that the teeth 113 are provided at two or more locations. Also, in this example, the force storage unit 13 is a spiral spring and is provided in the gear 141 of the power generation unit 14 . The gear 141 of the power generating section 14 rotates in conjunction with the rotation of the rotating section 11 . Energy is stored in the power storage unit 13 by rotating the gear 141 of the power generation unit 14 .

The operation of the power generation mechanism 10B shown in FIGS. 8(a) to 8(d) will be described below.
When the toilet paper TP rotates, the rotating part 11 rotates in the direction of the arrow in conjunction with it. When the rotating portion 11 rotates, as shown in FIGS. 8A and 8B, the teeth 113a of the rotating portion 11 and the gear 141 of the power generating portion 14 engage with each other, and the gear 141 of the power generating portion 14 It rotates in the opposite direction to the rotating part 11 . When the gear 141 of the power generating section 14 rotates in the direction opposite to that of the rotating section 11, the force storage section 13 provided in the gear 141 is tightened as shown in FIG. 8B. As a result, the energy generated by the rotation of rotating portion 11 is stored in force storage portion 13 . That is, the energy generated by the rotation of the toilet paper TP is stored in the force storage unit 13 .

When the rotating portion 11 rotates further, the tooth 113a of the rotating portion 11 engaged with the gear 141 of the power generating portion 14 is disengaged from the gear 141 of the power generating portion 14, as shown in FIG. 8(c). When the tooth 113a of the rotating portion 11 is disengaged from the gear 141 of the power generating portion 14, the rotational motion of the rotating portion 11 is no longer transmitted to the gear 141 of the power generating portion 14, and the force accumulating portion 13 attempts to return to its original state (loosen). . As a result, as shown in FIG. 8D, the gear 141 of the power generation unit 14 rotates in the same direction as the rotation unit 11 and returns to its original position, and the motor 142 of the power generation unit 14 generates power by electromagnetic induction. done. In this manner, the power generation section 14 may generate power using the rotational motion of the rotating section 11, for example.

When the rotating portion 11 rotates further, the tooth 113b of the rotating portion 11 engages with the gear 141 of the power generating portion 14 which has returned to its original position. By repeating this, power generation in the power generation unit 14 is repeatedly performed. In this example, the rotating part 11 rotates once while the toilet paper TP rotates once. While the rotating portion 11 rotates once, two teeth 113 provided on the rotating portion 11 generate electricity twice. By changing the number of locations where the teeth 113 are provided in the rotating portion 11, the number of times of power generation during one rotation of the rotating portion 11 can be changed.

As described above, according to the embodiment, even when the amount of toilet paper used is small, it is possible to secure a sufficient amount of power generation while suppressing the toilet paper from tearing, thereby reducing the use of the paper roll. It is possible to provide a paper winder capable of securely transmitting information to an external device.
