Through the movement of the paper, the device accurately reads the user's will. According to the present invention, even roll-up paper such as toilet paper, cooking paper, paper towel, and the like can be safely cut out by one hand, even for a person with a weak arm, an infant, an elderly person, or a person who is blind.

Description

Roll Paper Feeder {ROLL PAPER FEEDER}

The present invention is a roll paper which can easily pull out roll-shaped paper such as toilet paper, cooking paper, paper towel, and cut it safely with one hand, even if the one arm is inconvenient, infant, elderly person, or vision loss person. It relates to a supply device. And it is about whether the apparatus is a roll paper supply apparatus which does not need to consciously operate switches.

In the case of using a conventionally used paper holder, the paper is cut by pulling out the roll paper end with one hand, pressing the cover provided with the cutting blade with the other hand, and pulling the paper end strongly. there was. This series of tasks required the use of both hands at the same time, which was difficult for a person with one arm incapacity, an infant or an elderly person, or a person who lost sight. Therefore, in order to alleviate such difficulties even a little, an auxiliary device such as a spring is added to the cover provided with the cutting blades, and a force that is not so inconvenient to draw out the paper is applied to the roll paper. Some holders have been commercialized to push and cut the paper with one hand, but the direction, speed, and strength of pulling the paper at the time of cutting or pulling the paper during cutting are also commercialized. Unless it is added or subtracted, there are many things that cannot be pulled out or cut. However, in either of the above systems, whether the spring or the like is added to the cover provided with the cutting blade, the paper end remaining on the cut roll paper side is left behind the cutting blade and becomes unrecognizable. Therefore, the next user is first required to rotate the roll paper in the direction of pulling out by hand until the paper end can be seen and touched. Subsequently, it is required to pull off the paper edge which is pressed and stuck to the roll at the time of cutting using a finger or a fingernail. This work is extremely difficult when a person with low vision or total vision loss is in a state where one arm cannot be used, injuries to the fingers of the other arm that can be used, and a bandage is applied to the finger. to be.

  In order to solve this problem, there is an increasing number of patent applications of a manual or electric automatic paper feeder. At the time of filing the present invention, the applicant has not seen a commercially available automatic paper supply device, but a known automatic paper supply device according to a patent publication or the like generally includes the following components. Retaining device for holding roll-shaped paper in a rotatable state, automatic feeding device, adjusting device for feeding length, short and long switching switch of feeding length, automatic cutting device, accommodating part of paper cut and separated from roll paper, cutting Afterwards, the automatic feeder that sends out a certain length of paper, the switches that start each device, the control device for operating each device in the setting order, the sensors for the purpose of reliably operating the control device, and the control device Timers for the purpose of carrying out the operation, a main body case portion for accommodating these devices, and a lid of the case opening portion. Approximately this kind of apparatus is the basic component of the known automatic paper feeder. In addition, most of the inventions in which the patent pending invention and the utility model registration application are applied recombine these basic components, improve individual basic components, study the method of arranging or mounting the basic components, or control methods or settings. Efforts have been made to eliminate the drawbacks of conventional inventions and designs by studying the procedure and the like and adding and using devices other than the basic components. However, the details are often insufficient and many are difficult to use in practice.

In particular, the presence of switches is an obstacle in practical use. Any invention or design of the past requires the operation of switches such as a general push button switch, a foot switch or an infrared sensor switch, and is intended for an elderly person who has extremely low vision or a person who is completely blind. It is a very difficult task to confirm the existence of switches, to understand the functions of the switches, or to operate the functions assigned to the switches for each function. In addition, since the usability is different from the paper holders which are familiar to use in the past, when a conventional paper holder is suddenly changed to these known automatic paper feeders, a manual explaining how to handle the device is provided. It may be necessary to place it near the device and to impose another inconvenience on an elderly person who is extremely blind or whose eyes are completely blind so that the instructions cannot be read. Such manuals are generally difficult to understand for infants, and the emergence of new automatic paper feeders requiring operation of switches is also difficult for infants. Even if there is only one switch in person who has a little mental function, anxiety such as `` how do we do, should we do something, or do we not know something begins? '' It is also conceivable to fall into a situation where it is impossible to use a new automatic paper supply device.

This invention makes it a subject to obtain the roll paper supply apparatus which can pull out roll-shaped papers, such as a toilet paper, easily and cut | disconnects safely with one hand, even if the one arm is incapable, a person who has lost sight, etc. An object of the present invention is to provide a roll paper supply device that does not need to consciously operate switches, wherein the device reads the user's will through the movement of the paper.

The roll paper supply apparatus according to the present invention is characterized by accurately reading the user's will through the movement of the paper. Therefore, the user does not need to operate the switches in particular consciously, and can easily pull out roll-shaped paper such as toilet paper, cooking paper, paper towel, and cut safely with one hand. Anyone with a physical or mental disability, injury, etc., whose one arm becomes inconvenient, infant or elderly person, or who has lost sight, etc., does not have special switches required for operation. Even the first use can be used simply without great discomfort. Further, according to the embodiment of the present invention, in which the paper is not driven by a motor drive as in a known roll-shaped automatic paper feeder, only about 10 cm is driven by a motor drive after cutting in one use. Even if it pulled out 1m or 2m, since no power is required for paper delivery in the meantime, the power used for paper delivery is about one tenth or less compared with a well-known technique. In other words, when the independent roll paper supply device using a battery is commercialized according to the present invention, when the same battery is used as compared to the battery replacement time of the roll paper automatic supply device according to a known technique, it is about 10 times longer. It becomes possible to use over, and the energy saving effect obtained becomes very high.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail with reference to the accompanying drawings.

The high quality embodiment which is high in safety and hard to generate | occur | produce a failure is shown by the perspective view of FIG. The main body case part 1 has holding apparatuses 2a and 2b for holding roll-shaped paper in a rotatable state, a drive roller 3 of an automatic dispensing apparatus for dispensing a fixed length of paper after cutting, The outlet slit 4 of the cutting blade of the automatic cutting device, the paper pressing device 5a, 5b which is an auxiliary device of the automatic cutting device, the sensor 6 which reads the start and stop of the movement of the paper, and the spring The convex fixation devices 7a and 7b which are built-in and in an accessible state are provided. The main body opening cover 8 for setting the roll-shaped paper includes a sensor manual roller 9 for the purpose of operating the sensor 6 normally and a manual roller for the purpose of operating the device for dispensing the paper. (10), convex fixing devices 7a, 7b provided in the main body when the lid is closed, and fixing recesses 11a, 11b, which are fitted with each other, are provided at the rotational points 12a, 12b. It is set to the main body 1 in the state which rotated. 1 shows a state where the lid is opened so that the roll paper can be set. The holding apparatuses 2a and 2b shown in Fig. 1 protrude from the inner wall of the main body, and thus, roll paper cannot be set as it is, but the holding apparatuses 2a and 2b push out from the outer side of the main body to protrude into the interior and once again Since it has the same configuration as a knock-type ballpoint pen that is pushed in, it is a roll-shaped paper that is pulled once from the inner wall of the main body before setting the paper, and then pushed out after aligning the center of the roll center of the paper and the holding devices 2a and 2b. Can be kept in a rotatable state.

Fig. 2 illustrates a state in which the lid is set in the embodiment of Fig. 1, which is an embodiment of the roll paper supply device according to the present invention, and the roll paper is set so that the paper end 60 is slightly protruded from below the apparatus. As an abbreviated structure explanatory drawing, it is drawn in the ratio same as it extended | stretched longitudinally about the downward part of the apparatus compared with FIG. 1 for easy description. The code | symbol shown in FIG. 2 corresponds to the code | symbol shown in FIG.

Hereinafter, the order using the Example of this invention, and the operation | movement of each apparatus of each order are demonstrated concretely.

(Set of roll paper)

(1) First, the roll paper is set in the holding device with the cover open, the paper is placed in the passage of the correct paper, and the paper ends are laid down to expose about 3 cm to 8 cm from the lower part of the main body case part.

(Obstruction of the device)

(2) Close the cover.

(3) The width of the paper thickness direction of the passage through which the elongated paper passes is more than the extent that the paper can pass freely (around 0.5 millimeters) and less than the fingers of the infant (about 3 millimeters). Function and safety are ensured by designing the closed state in a state where the cover is completely closed.

(4) When the cover is completely closed, the magnetic sensor 13 installed in the main body case detects the magnetic force of the magnet 58 provided inside the cover, and sends a signal to the power control device to turn the first power switch ON. Thus, power can be supplied to the electric system in the apparatus. In such a configuration, when the lid is opened, any device cannot be operated, and safety during roll paper replacement is secured. Instead of using a combination of a magnet and a magnetic sensor, a cover of about 6 millimeters in height may be provided in the cover, a hole may be drilled in the main body case, and the power main switch may be placed in the hole, and the switch may be directly pressed by the cover. . If the size of the hole is made small so that the fingers of an infant cannot enter (about 3 millimeters in diameter), sufficient safety is ensured.

(5) By turning on the first power switch, the sensor 6 or other devices for detecting the movement of the paper pulling can be operated. In the embodiment of FIG. 2, a general rotary encoder type sensor is used for the sensor 6, and a paper is sandwiched between the sensor 6 and the sensor manual roller 9.

(6) The paper automatic feeding device is composed of a motor 14 having a speed reduction device and a power transmission pulley, a power transmission belt 15, and a drive roller 3 provided with a power transmission pulley. . Although the driving roller 3 and the manual roller 10 are stopped with the paper inserted for paper feeding, the shaft of the power transmission pulley mounted on the driving roller 3 is provided with a clutch, and Alternatively, the one-way clutch is provided so that even if the motor 14 is stopped, the driving roller 3 and the manual roller 10 can be freely rotated in the direction in which the paper is pulled out. Is in a state where it can be pulled out. The paper automatic feeding device is generally based on a method of inserting paper by using a pair or a plurality of pairs of rubber rollers, but it is also known by a method of inserting paper into a pair of conveyor belts.

(Paper pull start and cover lock) and (paper outlet width lock)

(7) When the paper starts to be pulled out by hand, the sensor 6 reads the start of the movement of the paper.

(8) By the signal of the sensor 6, the control device of the safety device operates, and the second power switch is turned ON.

(9) By turning on the second power switch, the lid is locked by an electronic lock or the like, and the lid is kept locked for the purpose of securing safety until the subsequent series of operation cycles are completed. As a specific electronic locking method, the simplest method is to prevent the movement of the convex fixation devices 7a and 7b, which are freely functioned by the spring shown in FIG. 1, from descending backwards using a solenoid or the like. . In the automatic supply of roll paper, it is most dangerous to cut the paper and to open the cover at the moment the sharp cutting edge protrudes forward or to insert a finger from the paper outlet, and at least the cutting operation cycle The cover needs to be kept locked until the cutting blade returns to the main body case, and the outlet of the paper is less than or equal to the width of the paper in the thickness direction of the baby (specifically, about 3 millimeters). You need to keep it in a state.

(Stop of pulling out paper)

(10) When the user pulls out a paper of a desired length, the user completely stops the drawing operation of the paper, or stops for a moment, but starts to pull out the paper again without being satisfied with the length of the drawing paper. When the length of satisfaction is reached, the pull-out is completely stopped.

 (11) The sensor 6 operates to read the stop of the paper movement. If the control device of the sensor 6 is programmed to recognize that the time when it is completely stopped is 0.3 seconds or more, for example, it is a complete "stop". It is judged that it is within the time of "embarrassed" or "interruption of one moment" without being recognized, and the sensor 6 continues to operate, and waits for complete "stop" for more than a set time.

(Cycle operation of paper automatic cutting device)

Fig. 3 is a schematic structural explanatory diagram in which part of the display of the sensor system and the paper automatic feeding device system is omitted for the purpose of explaining the cycle operation of the paper automatic cutting device system including the paper pressing device. The finger is already stopping the drawing.

(12) When the sensor 6 operates to convey the "stop" of the movement of the paper to the control device, as shown in Fig. 3, the paper pressing devices 5a and 5b for assisting the cutting are the main body case. It protrudes from the part 1, and inserts paper into the inner wall side of the cover 8, and the paper pressing apparatus 5a, 5b. The paper pressing device 5a, 5b is being fixed to the rear end of the cutting blade 17 via the compression springs 16a, 16b, and the motor 59 provided with the reduction device makes the gear 18 arrow 19. When it starts to rotate in the direction of, it advances in the direction of the cover 8 as a whole by engaging with the rack gear provided in the cutting blade 17, and the paper pressing apparatus 5a, 5b is the body case for the first time. When the paper protrudes from the part 1 and presses the paper, the tip of the cutting blade is not yet reached to the paper, and the motor 59 continues to rotate the gear 18 in the direction of the arrow 19 so that the compression spring ( The paper pressing devices 5a and 5b, which are pressed and contracted by 16a and 16b, press the paper more strongly. Moreover, it is preferable that the contact surface with the paper of the paper pressing apparatus 5a, 5b is a rubbery system which has many small protrusions for slip prevention.

 (13) When the motor 59 continues to rotate the gear 18 further in the direction of the arrow 19, the state becomes as shown in FIG. 4, and the paper is completely cut by the cutting blade 17. As shown in FIG. The motor 59 has a reduction device, which can rotate the gear 18 at a speed suitable for cutting, and also has a sensor that reads the rotation angle of the shaft of the motor 59, and the angle of the shaft corresponding to the position of the cutting blade. It is preferred that the motor is capable of reading and determining the forward and retracted positions of the cutting blade. As a method for determining the forward position and the retracted position of the cutting blade, a method of providing a projection on a part of the cutting blade and reading the forward position and the retracted position of the projection by two micro switches is also simple and effective.

(14) When the cutting of the paper is completed, the cutting blades 17, the paper pressing devices 5a, 5b and the like become the state of Fig. 5 via the state of Fig. 3. In the meantime, when the paper pressing devices 5a and 5b release the paper, the paper of the appropriate length cut from the roll is separated from the main body case part and remains in the user's hand. The state of each device of Fig. 5 is basically the same as that of each device of Fig. 2, but the paper is cut and the paper end is near the automatic cutting device, i.e., in the main body case part, so as to hold the paper end with a finger. The only difference is that it is in an impossible state. As a method of forward-retracting a cutting blade, a disk with a rounded convex portion is used in combination with a slide plate for moving back and forth with a long hole, and one rotation of the disk with a rounded convex portion is one of the forward retreat of the cutting blade. You may use well-known techniques, such as operation. Japanese Patent Laid-Open No. 5-111442 describes a technique of cutting a paper by moving a wave of a wave with approximately such a configuration. Moreover, even if it uses the well-known technique of installing a fixed blade in the cover side, rotating a blade in the main body side, rotating using a motor or a cam, and cutting a paper like a scissors or a crusher, do. Techniques for cutting like scissors or squeezers are described in detail in Japanese Patent Application Laid-Open No. 10-14811, Japanese Patent Application Laid-Open No. 9-206237, Japanese Patent Application Publication No. Hei 4-20340, Japanese Patent Application Laid-Open No. 6-19693, and the like. If the roll paper containing the perforated line for cutting for the purpose of assisting cutting is used, the position of the perforated line is read by an optical sensor, and the line which perforated at the position of a cutting edge can be stopped exactly. In this way, the cutting blade does not need to be a sharp blade made of metal, and a thin sheet of plastic whose tip is pointed to a little so as not to be damaged can be used. The paper pressing device, which is an auxiliary device for cutting, presses both sides of the line punched and presses a thin plate in accordance with the line punched, thereby sufficiently cutting the paper. In this way, even if the cover is opened when the safety device breaks down and the blade portion is pushed out, the blade portion is not a sharp blade, so that the user is not injured. In addition, as long as it uses the roll paper which the perforated line | wire contains, you may use the well-known technique which pulls and tears both sides of the perforated line | wire in addition to using a blade etc. as an automatic cutting device. For example, Japanese Patent Application Laid-Open No. 2002-515273, Japanese Patent Application Laid-Open No. 11-244189, and the like are described in detail in the method of reading or stopping the position of a perforated line by an optical sensor, or pulling and tearing both sides of the perforated line. It is known.

(Cycle operation of the paper automatic feeding device)

(15) When the cycle operation of the paper automatic cutting device is completed, and the paper pressing devices 5a and 5b return to the initial positions to secure the passage of the paper, the paper automatic feeding device starts to operate.

 (16) The paper automatic feeding device is programmed to stop after sending the paper by the set value by the control device, and the feeding is stopped when the set value is reached. The set value is determined as an appropriate amount by which the paper edge is stretched about 3 cm to 8 cm from the main body case part. As a control device for obtaining the set value, a method using a timer is simple, effective, and known.

(Return to initial state)

(17) When a signal indicating that the cycle operation of the paper automatic feeding device is completed comes out of the control device, the lock of the main body opening lid 8, which is coincident with the start of pulling out the paper, is controlled by the control device of the safety device. It is canceled | released, and the operation | movement, such as a roll paper exchange, can be made free.

Another embodiment of the invention is described.                 

The device for holding the roll-shaped paper in a rotatable state is, as shown in Fig. 6 or 7, in addition to the method of using the center axis of the roll as in the holding devices 2a and 2b shown in Fig. 1. 6 may be supported by the paper support points 20 and 21 so as to be freely rotated. The paper support point 21 is a part of the paper support roll 22, and the paper support roll 22 is provided for the purpose of smoothing out the drawing of the roll paper. You may add a paper support roll also to a position.

There are a number of choices regarding the type of sensor, the mounting method and the arrangement of the sensors that read the start and stop of the paper movement.

(For type that sensor reads rotation)

There is a method of attaching a sensor to the holding device 2a or 2b of FIG. 1 to read the rotation of the core cylinder of the roll paper. Moreover, the method of installing a sensor in the rotating shaft of the paper support roll 22 shown in FIG. 6 is also effective. Alternatively, a sensor may be installed on the rotation shaft of the driving roller 3 or the manual roller 10 shown in FIG. 2 to read the start and stop of the movement of the paper.

(When the sensor is a light sensor of the transmitted light receiving type)

As shown in FIG. 6, light rays from the light emitter 23 enter the light receiving sensor 25 through the paper fibers as shown by the arrow 24. When the paper starts to move, the state of the paper fiber in front of the sensor changes, and the intensity of light entering the light receiving sensor 25 through the paper fiber also changes. The light receiving sensor 25 sends a signal corresponding to the intensity of the incoming light to the control device, and the control device determines that the paper is moving while there is a change in the received signal, and no change is seen in the received signal even after the set time has elapsed. At this time, it is judged that the movement of the paper is completely stopped.

(When the sensor is a light sensor of the reflected light reception type)

As shown in FIG. 7, the light rays from the light emitter 26 proceed as shown by the arrow 27, reflect from the surface of the paper fiber, and enter the light receiving sensor 29 as shown by the arrow 28. When the paper starts to move, the state of the paper fiber in front of the sensor changes, and the intensity and direction of the light reflected from the surface of the paper fiber and entering the light receiving sensor 29 also change. The light receiving sensor 29 transmits a signal corresponding to the intensity or direction of the incoming light to the control device, and the control device determines that the paper is moving while there is a change in the received signal. It is judged that the movement of the paper completely stops when it becomes invisible. If the sensor is at the same level as the function level used in the image sensor mouse of the personal computer, the movement and the stoppage of some paper can be almost completely read.

FIG. 8 divides the main body opening lid 8 in FIG. 1 slightly above the sensor manual roller 9, and opens the upper lid 30 in the direction of the arrow 31 for the set of roll paper. A schematic structural explanatory diagram of an embodiment in which the lower cover 32 having the sensor manual roller 9 and the manual roller 10 is opened horizontally, and the holding apparatuses 2a and 2b using the core cylinder of the roll paper are raised. ) Is one of the embodiments which is not provided. The lower cover 32 is attached to the main body case part 34 so that it can be rotated by the hinge part 33 of a vertical direction, and is provided with the locking hook part 35. As shown in FIG. The locking hook portion 35 indicated by a dotted line is shown with reference to the position when the lower lid 32 is closed. In addition, the upper cover 30 is provided with a locking hook portion 36, and inside the side wall of the main body case portion 34, an upper cover lock device 37 and a lower cover lock device 38 for securing safety are provided. It is. When the set of roll paper is completed as shown in Fig. 8 and the user starts to pull the paper in the direction of the arrow 39 as shown in Fig. 9, the sensor 6 is connected to the sensor manual roller 9 of the paper. The movement is read and a signal is sent to the control device of the safety device, which controls the upper cover lock device 37 and the lower cover lock device 38 in the direction of the arrow 40 and the arrow 41, The upper lid 30 and the lower lid 32 are kept locked until the series of automatic cycles after the user stops pulling out the paper, that is, the paper automatic cutting cycle and the paper automatic discharging cycle, is completed. When a series of automatic cycles are completed, the control device of the safety device returns the upper cover lock device 37 and the lower cover lock device 38 to the initial state as shown in FIG. 8, and the user can change the roll paper or clean the whole device. Can be freely performed. 8 and 9 illustrate recesses 42 for cutting blades.

10 and 11 mainly describe the embodiment according to claim 5 in detail, which is a partial sectional view near the paper outlet. In FIG. 10, the distance between the main body case part inner wall part 43 and the cover inner wall part 44 is about 2 mm to 3 mm, and the cover member 45 is provided with a rotating member 47 via a pivot shaft 46. The width of the rotation member 47 is larger than the width of the paper, but the operation is sure. However, if the width of the rotation member 47 is located at the center of the paper, the width of the rotation member 47 is sufficient even if the width of the rotation member 47 is about 3 cm to 5 cm. Dispensing of the paper 48 is completed, and the paper 48 hangs in a natural state in the intermediate position as shown between the main body case part inner wall part 43 and the cover inner wall part 44.

11 shows a state where the paper 48 is pulled in the direction of the arrow 49. When the paper 48 is pulled in the direction of the arrow 49, the rotation member 47 rotates in the direction of the arrow 50 with the pivot shaft 46 as the axial center to move the metal pieces 51 to the metal pieces 52. Press on the convex part of. The contact of the metal piece 51 and the metal piece 52 causes a trigger current to flow to the control device that controls the entire device, so that the power supply device for the other sensor is kept in an ON state and the other sensor can function. . Moreover, the control apparatus which operates a paper automatic feeding device, a paper automatic cutting device, a device for ensuring safety, etc. according to a program together with another sensor also becomes a state which can function by turning ON a power supply device. Needless to say, it is possible to use already manufactured micro switches in place of the metal pieces 51 and the metal pieces 52. 10 and 11, the trigger switch is provided near the exit of the paper passage, but in the arrangement near the exit, the user's finger is placed on the trigger switch. In some cases, it may be in direct contact. The trigger switch is generally set to be sensitive to slight movement of the paper, and the production is delicate. Direct contact of the user's fingers with a delicate part may also cause malfunction. In such a case, place the trigger switch in the middle of the paper passage slightly away from the outlet. In that case, a part of the main body case part inner wall part 43 is dug into a smooth "shaped" shape, and a part of the rotation member 47 is deformed so that the recess may be followed. The paper is smooth in the form of being able to pass between a part of the deformed main body case part inner wall part 43 and a part of the deformed rotating member 47 (the interval is about 2 mm to 3 mm). '' In shape, it stretches by itself. The trigger switch is sensitive but not set to respond to the weight of the paper. When the user attempts to pull out the paper in such a state, the paper deformed into a smooth "ku" shape by its own weight becomes a straight state which is taut by the tension, and pushes the rotating member 47 deformed into a convex shape. It rotates so that it may turn down, and the metal fragment 51 and the metal fragment 52 inside contact and energize.

Another embodiment using a switch using centrifugal force as another embodiment of a trigger switch is shown next. FIG. 12 shows a state where the paper 53 is fitted into the driving roller 3 and the manual roller 10 in FIG. 1 or FIG. 2 and pulled in the direction of the arrow 54. The shaft of the drive roller 3 is equipped with a one-way clutch so that the drive roller 3 can rotate in accordance with the movement of the paper 53 without being affected by the motor 14 or the power transmission belt 15. Can be. The large gear 55 mounted on the drive roller 3 meshes with the small gear 56 to become a speed increasing device, and the centrifugal force switch 57 mounted on the shaft of the small gear 56 is a slight portion of the paper 53. Sensitive to movement, sufficient torque can be obtained and the switch is turned on. The trigger current from the centrifugal force switch 57 flows to the control device so that the power supply device for the other sensors is kept in the ON state, so that other sensors can function. In addition, the control device which operates a paper automatic feeding device, a paper automatic cutting device, a device for ensuring safety, etc. according to a program simultaneously with another sensor also becomes a state which can function by turning ON a power supply device. The trigger switch, which has a function equivalent to that of the apparatus shown in Figs. 10 and 12, can also be made by a method of indirectly contacting an electrical contact using a permanent magnet. As for the internal structure of the centrifugal force switch 57, a structure with a simple level well-known as the shining yo-yo etc. which are toys is sufficient.

The method of turning the centrifugal force switch 57 in the horizontal direction using a bevel gear is also effective as a method of improving the sensitivity of the sensor. In addition to the general centrifugal force switch having a spring, a weight and an electrical contact therein, a metal or encapsulated mercury is used. A centrifugal force switch may be used. As described above, by using the trigger switch together, the trigger switch first operates by pulling out the paper, whereby the power supply circuit for the sensor reading the start and stop movement of the paper is turned ON, and the sensor is first started. It is possible to achieve the energy saving effect of completely zeroing the power consumption when the roll paper supply is not used. The usual sensors used to control electrical devices always have electricity, so the sensors are always monitored. When an optical, electrical, or physical stimulus or the like is applied to the sensor, the control device to which the sensor is connected compares the stimulus before and after the stimulus is applied and reads the change, and according to the program is connected to the control device. Control and operate various devices. Therefore, in the case of providing a standalone roll paper supply device using a limited energy source such as a battery, it is a great disadvantage to continuously operate the sensor for 24 hours even at any current, and the combination of the trigger switch is a power saving effect. It is a very effective means to increase the If a household power supply dedicated to a roll paper supply device is prepared in a bathroom or the like, it goes without saying that a general electrical sensor, an optical sensor, or a physical sensor that requires power supply in a 24-hour system can be used. 11 and 12 and descriptions thereof, some examples of trigger switches are illustrated, and an example in which the power supply of the sensor is turned on by using the trigger current obtained is described. The sensor must be a sensor that physically detects the movement of the paper at the time of holding the paper edge and starts pulling it out. Start the program of the control unit by a signal from a sensor (including a trigger sensor) that reads when the user starts to pull out the paper from the movement of the paper, and cycle-operates the paper automatic feeding device and the paper automatic cutting device. An example is shown below. Eliminates common start switches (including proximity sensing switches as simple substitutes for push button switches arranged in a position visible to the user) external to known roll paper automatic feed cutting devices. By using the motion that the paper begins to pull out, the user's will is sensed by a sensor (including a trigger switch) that monitors the movement of the paper, and the program of the control device is started by a signal from the sensor. To do the necessary cycle operation. At the start of the program, the paper dispenser operates to feed out paper of the length set for wiping, then the paper cutter cuts the paper, cuts the paper, and then the paper dispenser operates again. It is possible to provide a roll paper supply device that performs a cycle operation of discharging the paper so that the paper edge extends from the discharge port in the same length as the finger is easily picked up and returning to the initial setting state waiting for the user's next paper pulling action. have. Even when a user in a situation where only one hand can be used for some reason uses the apparatus, unlike the known art, the user is reliably picking up the paper stage before the paper is started to be fed. Even if the paper is sent out at the same time as ON and the paper is cut abruptly to the set length, it does not create an unsanitary situation, such as the paper piece falling off the floor due to the failure to grasp the paper. In addition, although already mentioned, the trigger switch used as a sensor may be provided in any one of the rotating shaft regarding a roll paper, and the passage of a roll paper. If you want to use a known roll paper automatic feed cutting device equipped with an external start switch installed in the main body of the device with one hand, at the moment of pressing the switch (or at the moment of reacting the proximity sensor using infrared light, etc.) Since the discharge starts automatically automatically, the user must urgently grasp the paper stage with his hand pressing the switch, and the paper of the set length is ejected, cut and dropped to the floor while trying to grab. In particular, when a person with a physical or mental disorder tries to use, it is easy to fall into such a situation. In addition, in the case where a person who is totally blind has made use of the known prior art roll paper automatic feeding cutting device, it is a problem to first check the existence of the start switch, and if there is no special paper receiving stand, It's easy to imagine a situation where you can't hold paper well. According to the present invention, since the operation of the apparatus is started after the user starts to pull the paper end securely, such a situation does not arise. In other words, even if a person who has completely lost sight intends to use, the person can use the novel roll paper supply device according to the present invention almost in the same sense as using a paper holder which is familiar with conventional use. In addition, there are no visible switches (ie, operate this switch, push button switches of the type, or close proximity switches of the type, of the type). Even when the paper holder used so far is removed and replaced with a new roll paper supply device according to the present invention, the user feels only a sense of discomfort that the form of the paper holder seems to be something new. Since there is no need to provide any special explanation about this, it is also possible to smoothly introduce a new device in a good facility or the like. The first or second time the user started writing, "Huh? I feel the surprise of the paper coming out, but since it is already holding the paper stage and may be pulling it, the paper is automatically sent out, and even if the paper is cut automatically, no further confusion arises. You will feel comfortable using the device. In addition, since the main subject of the present invention is in the method of mounting and operating the sensor for reading the start and stop of the movement of the paper, detailed descriptions of power supply, wiring, electronic control system, drive system and centrifugal force switch are omitted. The present invention is not limited to the above-described examples and the like, but the embodiment changes due to the change of each component, the change of the mounting method, and the like. For example, in the embodiment shown in Figs. 8 and 9, an embodiment in which the upper cover 30 having the locking hook portion 36 and the upper cover lock device 37 is removed is shown as an example of the change. It is the removal of the cover and the locking device for the purpose of ensuring safety and preventing the occurrence of failure. This is called modified example A. FIG. In the modified example A, since there is no cover and the roll paper is pushed by hand while the paper is being sent out, the paper is pulled off when the power of the device for delivering the paper is sufficiently strong. Alternatively, when the device for dispensing paper does not have sufficient durability, the device for dispensing may be subjected to excessive load, and if such a device is repeated, the gear may eventually be broken or the dispensing roll may be remarkably worn out, thereby smoothly dispensing. Or a motor or a circuit board may heat up and fail. This is an example of a change in a slightly worse direction in terms of safety and durability. However, if it is considered at a level that aims at lowering costs due to cost reduction or repurchasing demand after being broken, it can be a new business. The case where Modified Example A is provided below the conventional paper holder already installed in the toilet of a general house is shown next as a construction example A. FIG. In the embodiment shown in Figs. 8 and 9, there is no device for holding the roll-shaped paper in a rotatable state, which supports the core cylinder of the roll paper, as in the conventional paper holder. In the conventional paper holder, since an apparatus for holding the roll-shaped paper in a rotatable state supporting the core cylinder of the roll paper is already attached, this is used. In Application Example A, the roll paper is set in a conventional paper holder and the paper end is pulled out a little longer so that the modified embodiment A can fit the paper. As a goal, the paper stages have a positional relationship as shown in FIG. In this way, the user can simply pull out the paper with one hand and cut it safely. The lower cover 32 is configured by the locking hook portion 35 and the lower cover lock device 38 so as not to open at least when the cutting operation of the paper is performed, so that the cutting blade is exposed and damaged. There is no work and minimum safety is maintained. This can be said to be good, ignoring the concern that a malfunction may occur by pressing the roll paper by hand. In the present invention, which aims to accurately read the user's intention, and simply pull out the paper with one hand and cut it safely, the cover, the locking device for the cover, and the roll-shaped paper can be kept in a rotatable state. The device or the like is useful for providing a good quality product that is easy to use, safe, and hard to fail, but is not an absolutely necessary component. In the construction example A, the user does not need to remove and dispose the conventional paper holder which is already installed, and may just purchase and install the modified example A of low price, omitting some parts. In view of the fact that it does not take the labor to remove and remove cheaply and does not generate garbage, the modification Example A which was considered an example of the change in the slightly worse direction which reduced safety and durability is also burdensome for low-income people, and is environmentally friendly One embodiment is. To read the start of the drawing of the paper means to read the user's will correctly, and to read the time when the drawing operation is stopped. At this point, I want to cut the paper. ”Is to accurately read the user's will. In the present invention, the device does not start operation simply by the user touching his hand or touching the paper lightly. The first time the user really grabbed the paper and started pulling, the user said, “The user pulled the paper. The user needs paper. ” Through the movement of the paper, the device accurately reads the user's will. The act of simply touching the paper or touching the paper lightly without the willingness to pull out the paper is not regarded as an action requiring the paper. According to the present invention, it is possible to obtain a roll paper supply device that operates by accurately reading the user's will.

As described above, the roll paper supply device according to the present invention is characterized by accurately reading the user's will through the movement of the paper. Therefore, the user does not need to operate the switches in particular consciously, and can easily pull out roll-shaped paper such as toilet paper, cooking paper, paper towel, and cut safely with one hand. Anyone with a physical or mental disability, injury, etc., whose one arm is not free, an infant or an elderly person, or a person who has lost their eyesight, does not have any special switches that require manipulation. Even the first use can be used simply without great discomfort.
