Description

  The present invention relates to an apparatus for presenting information for inducing resource saving.

  In recent years, global warming has been taken up as a major issue, and various efforts are being made based on the greenhouse gas emission reduction target under the Kyoto Protocol. For example, greenhouse gas reduction measures include efforts to reduce carbon dioxide emissions, in particular, by promoting energy conservation and switching to clean energy. Specifically, efforts are being made to convert the energy consumption of each office building into carbon dioxide emissions and to reduce the emissions.

  However, because greenhouse gases are caused by human activities such as energy consumption, it is difficult to achieve greenhouse gas reduction targets without raising individual awareness of global warming, and carbon dioxide emissions. The amount is continuing to increase.

  Therefore, as an individual-level approach to global warming, it has been proposed to separate garbage for recycling resources and to remove power plugs of unused electrical products from outlets. In addition, Patent Document 1 below describes an environmental load information providing device that measures the environmental load value of each electric product from the power consumption in use, informs the consumer of the numerical value, and promotes the reduction of consumption. ing. This apparatus obtains the carbon dioxide emission amount, the crude oil consumption amount and the like based on the power consumption amount of the electric product and presents it as environmental load information.

  However, human activities that impact the environment have a variety of forms, such as the use of paper that leads to deforestation, in addition to the use of electrical appliances in the above literature, so environmental load information based on power consumption is presented. Therefore, it is difficult to realize a reduction in environmental load only by inducing power saving.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a resource saving invocation device that presents information for inducing saving of paper resources based on the amount of paper resources used by human activities. To do.

The resource saving arousing device of the present invention is attached to a roll paper holder that rotatably holds a roll paper (e.g., toilet paper) wound in a cylindrical shape, and a drawing amount calculation means for obtaining a drawing amount of the roll paper; An information presentation unit for presenting information for invoking saving of paper resources based on the amount of withdrawal ;
The roll paper holder has a rotating member that contacts the roll paper held by the roll paper holder and rotates in the thickness direction of the roll paper that decreases as the roll paper is pulled out.
The drawing amount calculating means rotates when the rotating member rotates, and a magnet fixed to the shaft of the rotating member or another shaft interlocked with the shaft via a plurality of gears. An angle sensor that outputs a signal corresponding to the rotation angle of the magnet, an angle calculation unit that determines the rotation angle based on an output value of the angle sensor, and the drawer that is based on the rotation angle determined by the angle calculation unit It is characterized by comprising an amount-of-drawing calculation unit for obtaining the amount .

  In a specific aspect of the present invention, it has a conversion unit that converts the amount of withdrawal determined by the amount of withdrawal calculation means into the amount of wood that is the raw material of paper, and the information presentation unit presents the amount of converted wood To do.

  A data storage unit that stores the amount of drawer or the amount of wood; and an integration unit that obtains the total amount of drawer or wood stored in the data storage unit, wherein the information presentation unit includes the total Can also be presented.

Further, the data storage unit stores a table representing a relationship between the rotation angle of the magnet and the roll paper drawing amount, and the drawing amount calculation unit sets the rotation angle obtained by the angle calculation unit to the table. The amount of withdrawal can be obtained by comparing with.

  As a specific aspect of the information presenting unit, the information presenting unit is configured by a display device for visually presenting the information or a sound generating device for presenting the information by sound.

According to the present invention, the information presentation unit presents information for invoking the saving of paper resources based on the amount of roll paper drawn, thereby urging the roll paper user to save paper resources. As a result, it is possible to suppress deforestation that causes global warming. Specifically, the roll paper drawing amount obtained by the drawing amount calculating means can be presented as the information.
The roll paper pull-out amount is obtained by determining the rotation angle of the magnet based on the change of the magnetic field generated from the magnet fixed to the shaft of the rotating member or another shaft linked to the shaft via a plurality of gears. Based on this, the pull-out amount of the roll paper can be obtained.
Even if the amount of rotation of the rotating member is small when using roll paper, the output value can be increased by fixing the magnet to another shaft that is linked to the shaft of the rotating member via a plurality of gears. The rotation angle of the magnet accompanying the rotation of the rotation member can be obtained reliably. In this case, if a table representing the relationship between the rotation angle of the magnet and the amount of roll paper drawn is prepared, the roll paper drawing amount can be easily obtained by comparing the obtained rotation angle with the table. it can.

  Alternatively, by presenting the amount of wood that corresponds to the amount of roll paper drawn, the roll paper user can be reminded that the human activity of using paper is related to deforestation, Savings can be promoted more effectively.

  Also, by presenting the total amount of roll paper withdrawn or the amount of wood, the value to be presented increases day by day, so it is possible to more effectively encourage the paper user to save paper resources.

  Furthermore, the information for inducing the saving of the paper resources is surely presented to the roll paper user by visually presenting it with the display device or by presenting it with the sound by the sound generating device.

  FIG. 1 shows a state in which a resource saving and arousing device 1 for promoting saving of toilet paper is attached to a wall surface 2 of a toilet as an example of the embodiment.

  The resource saving and arousing device 1 is configured to draw out the amount (for example, weight) of the roll-shaped toilet paper 3 rotatably held by the paper holder 4 and to save paper resources based on the pull-out amount of the toilet paper 3. A main body 5 is provided which obtains the amount of drawer, converts the amount of drawer into the amount of wood that is the raw material of paper, and visually presents these.

  The paper holder 4 is rotatably supported between a pair of holding members 7a and 7b that rotatably hold the toilet paper 3 from both sides, and the holding members 7a and 7b, and covers the upper portion of the toilet paper 3. It is the thing of the general form which has these.

  The main body 5 displays the switch 10 as an input unit capable of inputting the waste paper mixture ratio of the toilet paper 3, the pull-out amount of the toilet paper 3 and the amount of wood corresponding thereto, and is input from the switch 10. A liquid crystal panel 11 is provided as an information presentation unit for displaying the used paper mixture ratio. The waste paper mixture ratio is set to 0% when the switch 10 is not pressed (initial state), for example, and increases every 10% when the switch 10 is pressed. Then, when the switch 10 is pressed five times and the used paper blending ratio is set to 50% as shown in the figure, after obtaining the amount of wood based on the drawing amount when the used paper blending ratio is 0%, the set used paper blending is performed. The value corrected by multiplying by 50% is displayed.

  In addition, in the holding member 7b on the right side of the paper holder 4, an angle sensor, which will be described later, outputs a signal corresponding to the rotation angle as the rotation member 8 rotates, and the signal is transmitted via the electric wire 13. To the main unit 5 side. On the main body 5 side, the drawing amount of the toilet paper 3 is obtained based on the signal sent from the paper holder 4 side, and this is converted into the amount of wood. Further, the main body 5 is supplied with electric power by inserting a power plug (not shown) provided at the tip of the power cord 14 into an outlet.

  FIG. 2 is an assembly view of the paper holder 4. Based on this figure, the assembly method of the paper holder 4 is demonstrated.

  The pair of left and right holding members 7a and 7b of the paper holder 4 are flat plates 16a and 16b each having a rounded side (front side in the figure), and a hollow cover 17a fixed to the flat plates 16a and 16b by bonding or the like. , 17b. Specifically, two holes 19a, 19b, 19c, and 19d are provided at the upper and lower portions of the rear portions of the flat plates 16a and 16b, respectively. The flat plates 16 a and 16 b are fixed to both sides of the rectangular plate 22 by screwing into screw holes 23 a and 23 b respectively provided on the upper and lower sides of the rectangular plate 22 constituting the back surface. In the center of the rectangular plate 22, two holes 24 are provided at the top and bottom, and the paper holder 4 is fixed to the wall surface 2 by screwing a screw passed through the hole 24 into the wall surface 2 of the toilet.

  As a procedure for assembling the paper holder 4, first, the flat plates 16a and 16b of the left and right holding members 7a and 7b are screwed to the left and right of the rectangular plate 22, respectively, and at the same time, the rotating member 8 is attached between the flat plates 16a and 16b. . Specifically, the rotating member 8 is formed of a rectangular flat plate made of resin or the like, and the front side is slightly bent downward, and the rear side portion is further rounded into a cylindrical shape, and the shaft 26 made of metal or the like. Has been driven in. Further, holes 28a and 28b through which the shaft 26 is passed are provided in the upper portions of the flat plates 16a and 16b of the holding members 7a and 7b. As a result, when the left and right flat plates 16a and 16b are screwed to both sides of the rectangular plate 22, if the shaft 26 of the rotating member 8 is passed through the holes 28a and 28b provided in the flat plates 16a and 16b, the rotating member 8 is moved. It can hold | maintain rotatably between the flat plates 16a and 16b.

  Next, a mechanism for outputting a signal of the rotation angle of the shaft 26 rotating with the rotation of the rotation member 8 by the pair of angle sensors 30 is assembled.

  First, the annular gear 32 is driven and fixed to the tip of the shaft 26 that is passed through the hole 28b of the right flat plate 16b. Thereby, when the rotating member 8 rotates about the shaft 26, the gear 32 rotates together with the shaft 26. At this time, it is preferable to leave a small gap between the gear 32 and the flat plate 16b.

  An annular projection 33 is formed integrally with the flat plate 16b at a position below the hole 28b provided in the flat plate 16b. An annular gear 34 having a smaller diameter than the gear 32 is driven into the center of the projection 33. One end of the short shaft 36 pierced with is fitted. The driving amount of the gear 34 to the short shaft 36 is preferably adjusted so that when the short shaft 36 is fitted to the protrusion 33, the pair of gears 32 and 34 are engaged. In addition, it is preferable to apply grease or the like to the fitting portion between the short shaft 36 and the protrusion 33 so that the short shaft 36 can rotate smoothly.

  Furthermore, it is preferable to adjust the gear ratio of the gears 32 and 34 so that the rotational speed of the short shaft 36 is larger (for example, twice) than the rotational speed of the shaft 26. Thereby, when the toilet paper 3 is used and the rotation member 8 rotates, even if the rotation angle is small, it can be converted into a large angle by the gear ratio and transmitted.

  Next, an annular magnet 38 is driven into the other end side of the short shaft 36 and is fixed in a state where the other end side of the short shaft 36 is slightly protruded. Then, a pair of angle sensors 30 for detecting the strength of the magnetic field that changes with the rotation of the magnet 38 is attached. As the angle sensor 30, for example, a monolithic type angle sensor in which a Si Hall element and a signal amplification circuit are integrally formed can be used, and a sensor having as small a detection error as possible (for example, about ± 0.5 °). It is good to adopt. The pair of angle sensors 30 are fixed to both ends of an L-shaped member 40 formed by bending a strip-shaped member at a right angle, and when the L-shaped member 40 is positioned under the magnet 38, And be positioned next to each other.

  The L-shaped member 40 is fixed (for example, bonded) to the inside of the cover 17b of the flat plate 16b so as to have the above-described arrangement configuration. Moreover, the electric wire 13 which sends the signal which a pair of angle sensor 30 outputs to the main body 5 side of the resource saving stimulating apparatus 1 passes through the hole 42 provided in the cover 17b.

  As described above, after the mechanism for detecting the rotation angle of the magnet 38 accompanying the rotation of the rotation member 8 is assembled, the cover 17b is fixed (for example, bonded) to the flat plate 16b, thereby the right holding member. 7b is formed. At this time, since the annular protrusion 43 is provided on the inner surface of the cover 17b, the other end side of the short shaft 36 that is rotatably fitted to the protrusion 33 on the flat plate 16b side is provided with the annular protrusion provided on the cover 17b side. The protrusion 43 is fitted. As a result, the short shaft 36 is rotatable in a state of being fitted to the annular protrusions 33 and 43 located on both sides. It is preferable to apply grease to the annular protrusion 43 provided on the cover 17b side so that the short shaft 36 can rotate smoothly.

  After assembling the right holding member 7b, the cover 17a is fixed to the left flat plate 16a, and the left holding member 7a is assembled. Thereby, a pair of left and right holding members 7a and 7b are formed.

  Finally, a method of assembling the paper holder 45 for rotatably holding the toilet paper 3 by the paper holder 4 will be described.

  The paper holder 45 includes a pair of semi-cylindrical members 46a and 46b each having a substantially cylindrical member vertically divided into two, and one semi-cylindrical member 46a has a thin round bar-like protrusion 47 at the left end, and Two-stage grooves 49a each having a groove with a different diameter in the longitudinal direction are provided at the right end. Specifically, the left end protrusion 47 is formed integrally with the semi-cylindrical member 46a, and the two-step groove 49a communicates with the small-diameter groove provided from the right end of the semi-cylindrical member 46a and the small-diameter groove. And a large-diameter groove provided. Also, the right end portion of the other half-column member 46b is provided with a two-step groove 49b having the same configuration as the two-step groove 49a provided in the half-column member 46a, and the respective half-column members 46a and 46b are combined. At this time, the two-step grooves 49a and 49b are assembled with each other.

  When combining the pair of semi-cylindrical members 46a, 46b, first, a headed head formed by connecting a projection 47 provided at the left end of the semi-cylindrical member 46a, a cylindrical portion 52 having the same diameter, and a disk 53 having a larger diameter than this. The member 54 is fitted into the two-step groove 49a of the one semi-cylindrical member 46a. Specifically, the cylindrical portion 52 of the headed member 54 may be made the same diameter as the small-diameter groove of the two-stage groove, and the disk 53 may be made the same diameter as the large-diameter groove. Then, the headed member 54 is fitted into the two-step groove 49a and moved to the right side, and the coil spring 55 is fitted into the gap between the disc 53 of the headed member 54 and the large-diameter groove of the two-step groove 49a. After that, the pair of semi-cylindrical members 46a and 46b are combined and fixed. Thereby, the headed member 54 is urged to the right end side by the coil spring 55 in the two-step grooves 49a and 49b, and the disk 53 is locked in the two-step grooves 49a and 49b.

  In order to hold the toilet paper 3 with the paper holder 4, the paper holder 45 is inserted into a hole provided in the center of the toilet paper 3, and then the left end protrusion 47 of the paper holder 45 is connected to the left holding member 7 a. The cylindrical portion 52 of the headed member 54 positioned at the right end of the paper holder 45 may be passed through the hole 57b provided in the flat plate 16b of the right holding member 7b through the hole 57a provided in the flat plate 16a. When the cylindrical portion 52 of the headed member 54 is passed through the hole 57b provided in the flat plate 16b of the right holding member 7b, the paper holder 45 is held on the holding members on both sides in a state where the cylindrical portion 52 is pressed with a finger from the tip side. It is preferable that the cylindrical portion 52 of the headed member 54 is inserted into the hole 57b provided in the flat plate 16b by using the restoring force of the coil spring 55, which is fitted between 16a and 16b.

  FIG. 3 is a block diagram of the resource saving alert device 1 of the embodiment.

This resource saving arousing device 1 is a specific means for presenting the amount of drawer of toilet paper 3 held in the paper holder 4 and the amount of wood corresponding thereto.

The withdrawal amount calculating means 60
A magnet 38 attached to another shaft 36 interlocked with the shaft 26 of the rotating member 8 described above;
As described above, the angle sensor 30 installed inside the holding member 7b on the right side of the paper holder 4 (FIG. 2),
An angle calculation unit 67 for obtaining a rotation angle of the magnet 38 based on a signal output from the angle sensor 30;
Based on the rotation angle obtained by the angle calculation unit 67, a drawing amount calculation unit 68 for obtaining the drawing amount of the toilet paper 3 is configured.

  As an arrangement configuration of each means, the magnet 38 and the pair of angle sensors 30 can be provided on the paper holder 4 side, and the remaining means can be provided in the main body 5.

  As a calculation method of the drawing amount of the toilet paper 3, there is a method of obtaining based on a table representing the relationship between the rotation angle of the magnet 38 and the drawing amount of the toilet paper 3 as shown in FIG. 4. Specifically, if this table is stored in the data storage unit 62 in advance, when the angle calculation unit 67 obtains the rotation angle of the magnet 38, the drawing amount calculation unit 68 illuminates the rotation angle against the table. By combining them, the amount of toilet paper 3 drawn out can be obtained. Further, in this table, “θ” is the rotation angle of the rotation member 8 of the paper holder 4 and is half the rotation angle of the magnet 38 corresponding to the gear ratio (here, twice). Yes.

  In addition, as a method for converting the amount of drawer paper 3 into the amount of wood used as a raw material, for example, there is a method of obtaining the amount based on the amount of drawer paper 3 and the amount of paper that can be made from a single tree. is there. Specifically, assuming that the amount of paper that can be made from a standing tree having a thickness of 14 cm and a height of 8 m is 42.2 kg, the conversion unit 61 calculates the amount of wood based on the drawing amount of the toilet paper 3 (for example, standing tree) Number) can be obtained by the following equation.

  Further, when the waste paper mixture ratio of the toilet paper 3 is set from the switch 10, the conversion unit 61 corrects the amount of wood obtained by the above formula 1 by multiplying the waste paper mixture ratio, and this is corrected. It can be presented as information.

  FIG. 5 shows the concept of the rotation angle of the rotation member 8 of the paper holder 4.

  In the embodiment, the state in which the rotating member 8 is placed on the new toilet paper 3 held by the paper holder 4 is set as the reference position (absolute angle θ = 0 °) of the rotating member 8, and the toilet paper 3 is used. Accordingly, the case where the rotating member 8 is rotated downward is defined as positive rotation. When the rotating member 8 is rotated from the position before use of the toilet paper 3 to the position after use, the rotation angle is represented by “Δθ”, and the rotation from the reference position to the position after use is performed. The moving angle is represented by “absolute angle θ”. This “absolute angle θ” does not represent the absolute value of the rotation angle in the calculation process, and is expressed as a negative angle from the reference position when the rotation member 8 is above the reference position. become. Further, when the new toilet paper 3 is used up, the absolute angle θ is 30 °, and the rotation angle of the magnet 38 (FIG. 4) is 0 ° when the rotating member 8 is at the reference position. It is good to adjust so that it becomes.

  FIGS. 6 and 7 are main flowcharts of the resource saving and arousing device 1 and show processing for obtaining and presenting the amount of drawer and the amount of wood corresponding to the amount when the toilet paper 3 is used.

  First, the resource saving arousing device 1 performs initial processing (steps [hereinafter referred to as ST] 1 to 3). This initial processing detects whether or not the rotating member 8 of the paper holder 4 is placed on the toilet paper 3, that is, whether or not the absolute angle θ is 0 ° or more when the rotating member 8 is stationary. It is a process to do.

  Specifically, at the same time when the power is turned on, the angle sensor 30 outputs a signal corresponding to the rotation angle of the magnet 38 (FIG. 3), and based on this, the angle calculation unit 67 obtains the rotation angle of the magnet (ST1), The data is sent to the control unit 65.

  And the control part 65 discriminate | determines whether predetermined time (for example, 5 second) passed since the angle change stopped (ST2). Specifically, the angle sensor 30 continues to send a signal representing the current position of the magnet 38 to the angle calculation unit 67, and the angle calculation unit 67 also obtains the rotation angle of the magnet and sends it to the control unit 65 accordingly. It is like that. The control unit 65 monitors the rotation angle based on the rotation angle sent 5 seconds before from the angle calculation unit 67, and the rotation angle changes within an allowable range (for example, ± 0.5 °). The above determination is made assuming that the angle change has stopped.

  When the determination of ST2 is “NO”, that is, when the control unit 65 receives a rotation angle exceeding the allowable range within the predetermined time from the angle calculation unit 67, it indicates that the rotation member 8 is rotating. Since it represents, it returns to ST1 again and repeats this until an angle change stops.

  On the other hand, when the determination of ST2 is “YES”, that is, when the value of the rotation angle received by the control unit 65 from the angle calculation unit 67 changes within the allowable range for 5 seconds, the rotation member 8 is regarded as stopped and the rotation is performed. It is determined whether or not the absolute angle θ of the member 8 is a positive value (ST3). Specifically, the control unit 65 may determine whether or not the rotation angle of the magnet 38 received from the angle calculation unit 67 is a positive value. This determination is “NO”, that is, the rotation angle of the magnet 38 is In the case of a negative value (absolute angle θ is also a negative value), it indicates that the rotating member 8 is located above the reference position (absolute angle θ = 0 °) and is not placed on the toilet paper 3, so ST1 again. The above initial process is repeated.

  On the other hand, when the determination of ST3 is “YES”, that is, when the absolute angle θ of the rotating member 8 is a positive value, the rotating member 8 is mounted on the toilet paper 3 or the toilet paper 3 is used up and the absolute angle θ = Since it indicates that the angle is 30 °, the initial processing is ended, and the process waits until the toilet paper 3 is used, specifically, until the rotation angle of the magnet 38 changes again.

  The control unit 65 constantly monitors the rotation angle of the magnet 38 sent from the angle calculation unit 67 during standby, and determines whether or not there has been a change in angle (ST4). Specifically, it is determined whether or not the value of the rotation angle sent from the angle calculation unit 67 is out of the allowable range (for example, ± 0.5 °), and this determination is “NO”, that is, the angle When there is no change, the above determination processing is repeated after waiting until there is an angle change.

  On the other hand, when the determination in ST4 is “YES”, that is, when the control unit 65 receives a rotation angle exceeding the allowable value from the angle calculation unit 67, it indicates that the rotation member 8 has rotated, specifically, toilet paper. Since the rotation member 8 is vibrated or the like when the path 3 is used, the control unit 65 changes the rotation angle received from the angle calculation unit 67 in order to detect the stop of the rotation of the rotation member 8. It is determined whether or not a predetermined time (for example, 5 seconds) has passed since the stop (ST5).

  If the determination in ST5 is “NO”, that is, if the rotating member 8 is still rotating, the determination in ST5 is repeated again.

  On the other hand, when the determination of ST5 is “YES”, that is, when the rotation of the rotating member 8 is stopped, for example, when the use of the toilet paper 3 is finished, the control unit 65 is configured to execute the above-described predetermined time (for example, It is determined whether or not the absolute angle θ and the rotation angle Δθ of the rotation member 8 after 5 seconds are larger than 0 ° (ST6). In this determination, the case where the absolute angle θ and the rotation angle Δθ of the rotating member 8 are each 0 ° is used as a reference when the rotating member 8 is lifted, for example, when the toilet paper 3 is replaced. In this case, the case (θ <0 °, Δθ <0 °) or the case where there is no angle change due to the vibration of the rotating member 8 (θ ≧ 0 °, Δθ = 0 °) is taken into consideration.

  When the determination of ST6 is “NO”, that is, when the conditions of the absolute angle θ and the rotation angle Δθ are not satisfied, for example, when the toilet paper 3 is replaced, the rotation member 8 is lifted and stopped. In this case, since the toilet paper 3 is not used, the process proceeds to ST4 again and the above process is repeated.

  On the other hand, when the determination of ST6 is “YES”, that is, when the conditions of the absolute angle θ and the rotation angle Δθ are satisfied, the rotation member 8 rotates in the positive direction (Δθ> 0 °). In addition, since it is below the reference position (θ> 0 °), there is a possibility that the toilet paper 3 has been used, so it is determined whether or not the toilet paper 3 has actually been used. Specifically, in the angle change determination process (ST4), the control unit 65 determines whether or not the absolute angle θ as a reference for the determination process in ST4 is 0 ° or more (ST7).

  When the determination of ST7 is “NO”, that is, when the absolute angle θ before the angle change is smaller than 0 °, for example, the rotating member 8 is lifted and stopped when the toilet paper 3 is replaced (θ <0 °). Later, when the rotating member 8 is placed on the toilet paper 3, the toilet paper 3 is regarded as not being used, the amount of drawer is not calculated, the process proceeds to ST4 again, and the above process is repeated.

  On the other hand, when the determination in ST7 is “YES”, that is, when the toilet paper 3 is used, the withdrawal amount calculation unit 68 obtains the withdrawal amount of the toilet paper 3 in accordance with a command from the control unit 65 (ST8). Specifically, the absolute angle θ of the rotating member 8 before the angle change or the rotation angle of the magnet 38 and the absolute angle θ after the angle change or the rotation angle of the magnet 38 are set as the rotation angle of the magnet 38 or the rotation member 8. The amount of withdrawal is obtained by comparing with a table (FIG. 4) showing the relationship between the absolute angle of the toilet and the amount of withdrawal of the toilet paper 3. More specifically, for example, if the magnet rotation angle before the angle change is 24 ° and the magnet rotation angle after the angle change is 25.5 °, the pullout amount corresponding to the magnet rotation angle 24 ° is 88.17 g. The pull-out amount corresponding to the magnet rotation angle 25.5 ° is 92.855 g by appropriately dividing the pull-out amounts corresponding to 25 ° and 26 °. Therefore, the drawer amount of the toilet paper 3 this time is “92.855-88.17 = 4.685 g”.

  Next, the conversion unit 61 converts the drawing amount of the toilet paper 3 obtained in the above ST8 into the amount of wood based on the command from the control unit 65 (ST9). Specifically, assuming that the withdrawal amount is 4.685 g as described above and the waste paper mixture ratio is 50%, the amount of wood can be obtained from the above equation 1 by the following equation.

  Then, the control unit 65 stores the amount of drawer (ST8) obtained by the drawer calculation unit 68 and the amount of wood (ST9) obtained by the conversion unit 61 in the data storage unit 62 (ST10). Thus, data is accumulated in the data storage unit 62 every time the toilet paper 3 is used.

  After storing the data in the data storage unit 62, the control unit 65 causes the integration unit 63 to calculate the total amount of drawer and wood stored therein (ST11). In addition, this integration process can be completed by integrating the already stored data when the control unit 65 stores the drawing amount and the amount of wood in the data storage unit 62. Further, the control unit 65 or the integrating unit 63 has a clock function, and can perform an integrating process based on an arbitrary period such as a month or year by an appropriate setting.

  Finally, the control unit 65 displays a predetermined message on the liquid crystal panel 11 of the main body 5 (ST12). In the resource saving and arousing device 1 of the embodiment, the control unit 65 is the sum of the waste paper mixture ratio input from the switch 10, the amount of drawer of the toilet paper 3 this time, and the amount of wood consumed during this month (the amount of standing trees used). Is displayed on the liquid crystal panel 11 of the main body 5 (FIG. 1).

  Thereafter, the process proceeds to ST4 again, and the above processing is repeated every time the toilet paper 3 is used.

  As described above, if the resource saving arousing device 1 of the embodiment is installed on the wall surface 2 of the toilet, etc., the amount of toilet paper 3 used by the user can be confirmed and the amount of increase / decrease since the previous use can be known. It is possible to pay attention to excessive use of the toilet paper 3. Furthermore, by displaying the total amount of standing trees used during the current month together with the amount of drawers, it is possible to recognize again that the human activity of using toilet paper 3 leads to deforestation that causes global warming. It is possible to further save the savings of par.

  As described above, the resource saving invoking device 1 according to the embodiment has been described. However, the present invention is not limited to this, and for example, the resource saving invoking device 1 includes a speaker that can output sound instead of the liquid crystal panel 11 as an information presentation unit. It is also possible to output a message by voice in ST12 of the main flowchart (FIGS. 6 and 7).

  In the embodiment, the total amount of used paper, the current amount of drawers, and the total amount of standing trees used for the current month are displayed on the liquid crystal panel 11, but the total amount of drawers for the toilet paper 3 is displayed. The amount of wood used corresponding to the amount of drawer may be displayed, and the content of the message to be displayed can be arbitrarily combined. In this case, if the voice generation device is employed as the information presentation unit, the same content can be presented by voice.

  Alternatively, in the embodiment, the control unit 65 or the integration unit 63 has a clock function, and performs an integration process based on an arbitrary period such as a month or year by an appropriate setting. Obtain the total withdrawal amount within the last 24 hours, multiply the total by 30 times or 365 times, obtain the expected total withdrawal amount for one month or one year, and present this to the information presentation unit Can do. In this case, the calculated expected value can be converted into the amount of wood and presented as environmental load information.

  Further, in the embodiment, as the drawing amount calculating means 60 for calculating the drawing amount of the toilet paper 3, the magnet 38, the angle sensor 30, the angle calculating unit 67, and the drawing amount calculating unit 68 are provided, and the rotation angle Δθ of the rotating member 8 is provided. Alternatively, the amount of pull-out is obtained based on the rotation angle of the magnet 38. As another method, for example, a means for detecting the number of rotations at an appropriate location (for example, the rotating member 8) of the paper holder 4 (for example, personal computer operation) If a disk equipped with a rotary encoder used for a ball-type mouse is rotatably provided and this roller is in contact with the toilet paper 3, the number of rotations of the roller rotating with the toilet paper 3 and the outer periphery of the roller From this relationship, the length of the used paper can be obtained. In this case, if a formula or table representing the relationship between the paper length and the amount of wood used is prepared, the amount of wood used can be obtained by comparing the obtained length of paper. Further, if printing is performed in advance in the winding direction of the toilet paper 3 at predetermined intervals (for example, dots are printed), and this is detected by a sensor, the sensor is moved as the toilet paper 3 is pulled out. It is also possible to calculate the drawing amount based on the number of detected prints (points) and the interval between them. The above drawing amount calculation method is not applied only to the toilet paper 3 in the embodiment, but can be applied to any roll paper.

  In other words, in the embodiment, the use of the toilet paper 3 is taken up as a utilization form of the paper resource. However, in addition to this, a configuration of a roll paper wound in a cylindrical shape and a roll paper holder that rotatably holds the roll paper is provided. If so, information for inducing saving of paper resources can be presented on the basis of the amount of roll paper drawn, as in the embodiment. As the roll paper, various roll papers for printers, plotters, FAX machines, cash registers (so-called registers), or any roll papers used in various industries can be adopted.

  Alternatively, in the drawing amount calculation means 60 in the embodiment, when the turning member 8 is turned in the thickness direction of the toilet paper 3, the drawing amount of the toilet paper 3 is obtained based on the turning angle. In addition, the paper holder 4 is provided with a member having an appropriate shape that is urged so as to vertically contact the outer peripheral surface of the toilet paper 3, and moves toward the center of the toilet paper 3 as the toilet paper 3 is used. By determining the amount of movement of the member, it is possible to calculate the amount of drawer of the toilet paper 3. In order to urge the member toward the toilet paper, for example, the member is formed in a rod shape having a protrusion on a part thereof, and a coil spring fitted in the rod-shaped portion is locked on the protrusion. The coil spring can urge the protrusion to urge the member toward the toilet paper 3 side. In this case, if the relationship between the moving amount of the member and the drawing amount of the toilet paper 3 is tabulated, the drawing amount can be easily obtained.

  Moreover, as information for stimulating the saving of paper resources, in addition to the amount of wood corresponding to the amount of withdrawal of toilet paper 3 in the embodiment, an amount corresponding to the amount of withdrawal of arbitrary roll paper can be presented. . In this case, as in the embodiment, the amount of roll paper withdrawn and the amount corresponding thereto are tabulated, so that the amount can be obtained simply by comparing the obtained amount of withdrawal with the table.

  In yet another aspect, based on the amount of wood corresponding to the amount of roll paper drawn, the amount of carbon dioxide that is no longer consumed when the wood is cut down can be obtained and presented as environmental load information. Specifically, assuming that the amount of carbon dioxide consumed in one day by the wood used as the raw material for the roll paper (standing tree having a thickness of 14 cm in the embodiment) is 40 g in terms of carbon, The amount of carbon dioxide that is no longer consumed when the amount is a (g) can be determined by the following equation.

The carbon dioxide amount calculation process may be performed by the conversion unit 61 (FIG. 3), or a CO ₂ calculation unit for performing the process may be separately provided. By presenting the amount of carbon dioxide thus determined as environmental load information, the paper user can be more effectively encouraged to save paper resources.

  In addition, paying attention to the fact that standing trees absorb and accumulate carbon dioxide by photosynthesis, when the timber is cut down, the amount of carbon dioxide released into the atmosphere from the timber is obtained in advance, It is also possible to present the amount of carbon dioxide released into the atmosphere as information for promoting saving of paper resources based on the amount of wood corresponding to the amount of withdrawal. Specific estimation conditions and examples are shown below.

<Calculation conditions>
(1) The thickness of the standing tree is 14cm,
(2) The height of the standing tree is 8m.
(3) The carbon content of standing trees is 50% (from the Environment Agency: “Global Warming Earth / Japan Initiatives” H6.12),
(4) The volume density ratio of standing trees is 450 kg / m ³ (see above),
(5) The volume of the standing tree is 3.14 × 0.07 ² × 8≈0.123 m ³ ,
(6) The molecular weight ratio between carbon dioxide and carbon is 44/12,
<Example of trial calculation>
From the above conditions, the carbon content contained in one tree is converted into the amount of carbon dioxide by the following equation.

  Therefore, the carbon dioxide emission based on the amount of felled trees (number) is obtained by the following equation.

The carbon dioxide emission calculation process based on the above equation (5) may be performed by the conversion unit 61 (FIG. 3) of the paper resource saving device 1 or the calculation of CO ₂ emission for performing the process. A part may be provided separately.

  As described above, in order to encourage the user of the roll paper to save paper resources, the amount of roll paper drawn, the amount of money equivalent to this, or the amount of timber, and timber is no longer consumed by being cut or By presenting various information such as the amount of carbon dioxide emitted, it is possible to effectively save paper resources for any person with different values.
