Description of the invention (1) [Utilization field in the industry] The present invention relates to a paper shredder for a device for shredding paper. Most security agencies that avoid danger. Specifically, a structure for stopping the rotating blade of the shredder quickly and safely in an emergency will be disclosed. At the same time, it also discloses a structure in which the rotary blade is automatically rotated to start cutting according to the existence of Xuan_1, or the rotary blade is stopped and the cutting is ended. In addition, we will disclose the structure to avoid danger when the waste bins are formed of plastic or other materials that are easy to bend. [Knowledge Techniques] Whether it is for office or home use, the shredder is a structure that cuts the paper according to the rotating blade, so you must consider the safety of the human body. However, if the blade is turned in the moving mechanism when the dust bin storing the scraps of paper has been pulled out, it is very dangerous when the operator accidentally reaches into the dust bin. Therefore, in order to avoid such danger, it is necessary to surely stop the rotation of the blade when pulling out the dustbin. Then, in the normal shredder, as the operation switch, there are three kinds of switches: forward (cut) switch, reverse switch, and stop switch. That is, it is the person who cuts the paper automatically based on inserting the paper to be cut into the input port, or by pressing the forward switch and the internal shredder cutter will rotate. At the same time, when paper jams occur during cutting, the paper can be ejected and removed by reversing the rotating blade by pressing the reverse switch. On the one hand, the stop is established after the cutting of documents, etc., or to stop the rotating blade during rotation in case of emergency. This paper size applies to the Chinese National Standard (CNS) A4 specification (210X 297 mm) ~- ------- # ------ Ιτ (please read the notes on the back first and then fill in this page) -4-304893 A7 B7 5. Invention description (2) (please read the notes on the back first (Fill in this page again) Then, most of these switches are placed near the paper input port on the top plate of the cutting section. Most of the switches are designed to be the same size. The switch buttons are of the same height and are pushed into the top plate. Press down to make it act. Then, according to the function display of the font near the switch, or the shape or color of the head of the switch button respectively indicate its function. However, because the paper inlet is relatively wide, depending on the unfamiliarity or care of the operation, the user's clothes or tie may be caught in the rotating blade. At this time, it is very difficult to press the small stop-to-open relationship buried in the top plate. The reason is that users who panic due to unexpected accidents cannot operate the switch calmly. The Ministry of Economic Affairs, Central Bureau of Accreditation, and Employee Consumer Cooperatives printed and then used I as the above-mentioned automatic operation mechanism. Usually, a perceptron is installed at the paper inlet, and the rotary blade is controlled by the perceptron when detecting the existence of the paper At this time, there is a certain distance between the detection position of the perceptron and the position of the cutting part of the rotating blade, so even if the end of the paper has passed the perceptron and no paper exists in the perceptron, the actual The terminal of the paper has not reached the rotating blade. Therefore, until the cutting is completed, the rotary blade needs to be temporarily rotated. However, at this time, because the ._delay circuit needs to be installed, the circuit becomes complicated, and there is a problem that it takes time to manufacture. On the one hand, as a sensor, a mechanical start lever is provided, and a paper shredder of a type that directly turns on the drive motor power of the rotary blade according to the paper pushing the start lever can be manufactured relatively cheaply, but when the paper passes through the start lever After that, the micro switch will become off, and the drive motor will stop before the paper completely passes the rotating blade. Therefore, it is necessary to manually press the forward switch or the like until the cutting is completed, and then the motor is rotated. This paper standard is universal Chinese National Standard (CNS) A4 specification (210X297mm). The Central Standards Bureau of the Ministry of Economic Affairs Employee Consumer Cooperative Indun A7 B7 V. Invention description (3) At the same time, other hazards must sometimes be considered in the shredder Sex. That is, if the paper shredder is to be assembled inexpensively and simply, its material is usually formed of synthetic resin such as plastic for the purpose of light weight and mass production. However, since the paper shredder of the above-mentioned form is made of plastic and other materials that are easy to bend and contain, the side wall 9 is added to the trash bin (drawer) 9 0 as shown in the 2nd to 5th. 1 will be deformed inward, and a gap will be formed between the cutting portion 9 2 and the finger, and there is a risk that the finger may enter the cutting portion 9 2 from the gap. This point becomes more serious when the trash can is pulled out, and the bottom is deeper. Therefore, these problems must be solved in order to avoid danger. [Summary of the Invention] The first object of the present invention is to provide a mechanism that will stop the operation of the cutter when the waste bin is pulled for safe operation of the shredder. As the second purpose, it makes the switch for emergency stop easy to use, and provides a mechanism for users to easily perform emergency stop in the event of an accident outside the sound. «〇 For other purposes, it is to provide shredded paper when the paper is put in The mechanism that detects the machine when the machine is in operation, and the machine that stops the cutter if it is detected when there is no paper, is a mechanism that can automatically start and stop automatically without using a light sensor, etc. At the same time, in the garbage When the box is made of easily bendable plastic, etc., a mechanism for correcting the bend is provided. Specifically, in order to achieve the first object, a safety mechanism for a paper shredder in the form of a drawer-type trash bin will be developed on the lower side. In this institution, this paper scale is applicable to the Chinese National Standard (CNS) A4 (210X 297mm) ~ '1 (please read the precautions on the back and then fill out this page) -install · *-° A7 B7 5. Invention Description (4) It is on the side wall at right angles of the drawer direction of the garbage bin, that is, the upper part of any one of the wall surfaces in the front wall-type deep wall, and an operation piece for operating the switch is protruded. Then, an actuator that operates the switch using a position-operating piece that closes the trash can, according to a device that closes the drive power of the rotary blade and supplies power to the rotary blade. According to the opening relationship of the actuator Ο N · 〇 F F, it is set in the middle of the drive power circuit of the rotating blade. When the dustbin is closed, the operation piece will press the actuator, and the circuit will be closed to supply power. More specifically, an operation piece is protruded above the front side wall of the trash bin, and a slit through which the operation piece passes is provided at a position corresponding to the operation piece under the cutting part, and a micro switch is provided inside the slit The lower cover of the actuator adopts a device in which the operation piece operates the actuator in the closed position of the waste bin. As a basic structure for achieving the second object, the present invention is to arrange a wide area switch board that is often upwardly urged on the same plane as the top plate of the cutting portion, and at any position directly below the switch board , Set the mi that will stop the rotating blade according to the lowering of the switch board. At the same time, the support body of the Central Standards Bureau of the Ministry of Economic Affairs of the Ministry of Economics, the Consumer Cooperative Printing Co., Ltd. is printed on the two sides of the inner side of the top of the cutting section. Please read the precautions on the back before filling in this page), and freely turn the front end of a pair of action levers to install a switch board with a larger area than the other switches. The switch board is fixed to the top plate with a wide spring plate upward It is supported by a booster, and at any position directly below the switch board, a micro switch that operates according to the lowering of the switch board and stops the rotating blade is provided. Therefore, the stop switch is based on the switch that boosts the switch upward. The area of the board is widened, and even in an emergency, the switch board can be lowered by small movements of the hand type body without realizing the position of the switch board. This paper scale is applicable to the Chinese National Standard (CNS) 84 specifications (210X297 mm) ~ —: -7-304893 _ ^ _ Fifth, the description of the invention (5) The internal micro switch will act, and it really stops the rotating blade. In order to achieve the third object, in the present invention, the paper detection plate protruding from the paper input port is fixed to one end of the detection plate protection frame supported as a freely rotating transmission shaft, and the other end of the transmission shaft The start lever is fixed so that the paper detection plate and the start lever can rotate in conjunction with each other. Then, the actuator of the micro switch comes to the front end of the start lever, and rotates in conjunction with the rotary blade. On the outer side of the switch cam that operates the actuator, a push-up protrusion is provided in the circumferential direction. The front end of the movable piece of the start lever stopper provided in the frame is provided with a locking protrusion protruding in the rotation area of the above start lever. At the same time, the above problem is solved according to the configuration of the protrusion for releasing the installation at a position where the protrusion on the outer side of the switch cam can be stopped. Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the notes on the back of V Dan to fill in this page) According to the above structure, in the present invention, the paper detection board will rotate when the paper is inserted, and it will be linked through the transmission shaft The starter lever will rotate and push the actuator of the micro switch to drive the drive motor to rotate the rotating blade to start the cutting. At this time, even if the end of the paper is detected, the start of the lever is temporarily prevented from being restored by the locking projection, and the actuator is further pushed by the cam surface of the switch cam to rotate the rotary blade, and then the switch cam is rotated Pushing up the protrusion pushes the start lever stopper outward, releasing the lock of the start lever to return it to its original state, and stopping the rotating blade from rotating. Therefore, after detecting the end of the paper until the lifting protrusion of the switch cam releases the locking of the start lever, the rotating blade will continue to rotate until the end of the paper can be completely cut. In order to achieve the fourth object, in the present invention, a device for freely rotating a safety guide with a stopper at a position where the side wall is curved inwardly corresponding to at least the upper edge of the side wall of the trash can is used to freely rotate in the pull-out direction of the trash can This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X 297mm) ~~ -8-Printed and printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs j 304893 _ ^ _ V. Invention description (6). According to this mechanism, the stopper of the safety guide, when the force is applied to the trash can from the side, will contact the curved side wall, and the regulatory side wall is deformed further inward, so it will not occur between the cutting part and the trash can A gap where fingers can enter. At the same time, because the safety guide is free to rotate in the pulling direction of the trash bin, the trash bin can be freely entered and exit without hindrance. Furthermore, in the present invention, the stopper "at least corresponds to the upper edge" is an essential element. This is because the inward bending of this part can be achieved only by contact with the upper edge, and the goal can be achieved. However, it is not limited to this. The greater the width of the stopper and the contact width with the side wall, the greater the effect of preventing deformation of the side wall. Other configurations and benefits that can be obtained from the present invention will be easily understood by referring to the following drawings and examples. [Examples] Hereinafter, an example of the present invention will be described in detail based on the drawings. Figure 1 is a perspective view of a paper shredder constructed using the present invention. 1 is a cutting part, and a rotary blade (not shown) is provided on the inside.

After that, when the push-up protrusion 65 of the switch cam 64 pushes up the release protrusion 70 of the start lever stopper 6 6, the lock of the lock member 73 will fall off, and the start lever 63 will move according to the trend Revert to the initial state. In this embodiment, since the structure of the locking member 73 does not require the rocking shaft 67 or the like, the structure will be extremely simple, so that it is possible to reduce the manufacturing cost and the like. However, at this time, when the lever 63 is activated to push the locking member 73 outward, the elastic force of the movable piece 6 6 a needs to be rotated to advance, so that the paper to be cut will become pressable. The thickness of the paper detection plate 59. As such, the automatic start of one object of the present invention, the automatic stop mechanism, is the function of rotating the rotary blade for a certain time after the detection paper is completed. The implement of the cam mechanism is not cost-effective because it is not based on another circuit as in the past.

Please note before filling this page) Finally, the ideal embodiment of the fourth purpose of achieving cost inventions is explained. In this embodiment, for example, as shown in Fig. 1, when the waste bin 3 and the storage bin 4 are made of lightweight and mass-produced materials, and are made of materials that are easily bent, such as plastic, they are used to avoid danger to the human body. Figure 2 1 is a perspective view showing the relationship between the safety guide 8 1 and the trash bin 3 as an ideal safety device. For the sake of convenience, the cutting part 2 and the storage box 4 and the frame 5 in the figure 1 are omitted. . This embodiment corresponds to the upper edges 3b, 3b of both side walls 3a, 3a of the trash bin 3, and the paper size is applicable to the country of China according to the safety of the stoppers 8 1 a, 8 1 a located inside Standard (CNS) A4 specification (2 丨 OX297mm) ~ 7-21-A7 _B7_ printed by the consumer cooperation of the Falcon Bureau of the Ministry of Economic Affairs A5 _B7_ 5. Description of the invention (i9) Guide 8 1, the shaft stops at the lower cover The guide bracket 2 a formed by 2 constitutes a safety mechanism. At the same time, the stoppers 81a and 81a are connected to each other by a connecting member 82, and the entire shape constitutes a concave crank shape. According to this configuration, as shown in FIG. 22, even if an external force P is applied to the inside of the trash bin 3 from the side, the stopper 8 1 a will come into contact with the upper edge portion 3 b and the side wall 3 a can be regulated further inward Deformed. Therefore, there is no space between the trash bin 3 and the lower cover 2 where fingers can enter, and even if the trash bin 3 is formed of a material that is easily bent, fingers do not enter the cutting portion 1 and are safe. At this time, when the space for the dustbin 3 to be taken out smoothly is provided between the stopper 8 1 a and the side wall 3 a, although it is possible that this part will bend with the side wall 3 a and a safety guide 7 will move to the left and right, but in this embodiment, the length L of the connecting member 82 and the inner width W of the trash bin 3 are adjusted accordingly to minimize the above-mentioned gap, so there is no basis for the safety guide 8 1. The disadvantage of mobile. In addition, as a shaft stop device that regulates the movement of the safety guide c 8 1, although there is a split pin placed in the shaft portion 8 1 b of the safety guide 7, the use of other well-known devices does not have the structure of the present invention Any impact. On the one hand, the safety guide 81 is free to rotate in the pull-out direction of the trash bin 3, as shown in FIG. 23, usually the safety guide 81 in the overhang state will be attached to the back of the trash bin 3 The board 3c rotates forwards and backwards, so that the trash can 3 can be put in and taken out without hindrance. At the same time, when the trash can 3 is taken out and put in again, the connecting member 8 2 will rotate, and according to the stirring action at this time, it will function to make the cut shoulder accumulated in the trash can 3 to a certain degree of flatness. The size of the rotating blade to prevent clogging based on cutting chips is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) *-22---------- ^ ------ IT ί ( Please read the back-precautions before filling in this page) A7 B7 304893 Five, invention description (2〇) shortcomings and other shortcomings "Next, according to Figure 2 4 to illustrate other embodiments of the safety mechanism" This embodiment is based on The connecting member 8 2 is a first embodiment in which the stopper is integrated, and the connecting member 8 2 is omitted, and the safety guide 83 is configured separately from left to right. At this time, according to the configuration in which the shaft portions 83b and 83b do not fall off the guide bracket 2a, the deformation of the side walls 3a and 3a to the inside can be regulated as in the above embodiment, and the trash can can be freely carried out at the same time 3 Take out and put in. Furthermore, although in the above two embodiments, the lower cover 2 is formed separately from the cutting portion 1 as a guide bracket 2 a that secures the safety guides 8 1 and 83 to the lower cover 2, the lower cover 2 and the cutting part 1 are integrated, or when the lower cover 2 is omitted, the safety guides 8 1 and 8 3 may be directly axially locked to the cutting part 1. At the same time, although in the two embodiments, the safety guides 8 1 and 8 3 are provided corresponding to one place on the side wall 3 a, but the corresponding place is not limited by this, and the majority The safety guides 8 1, 8 3, and more accurately regulate the deformation of the side wall 3 a. However, if the safety guides 8 1, 8 and 3 are provided corresponding to one place of the side wall 3a as in the two embodiments, the stopper 7a will be positioned in the middle of the side wall 3a and the safety guides 8 and 8 are provided. 3 is ideal. The reason is that it is on the side wall 3 a of the waste bin 3, and the middle is the most easily deformed. • The stopper 8 1 a is only in contact with the upper edge of the side wall 3 a. Of course, the stopper 8 1 a is lengthened. The greater the range of contact with the side wall 3 a, the greater the effect of preventing deformation of the side wall 3 a. In this way, in the various embodiments used to achieve the fourth objective, even in the paper standard, the Chinese National Standard (CNS) A4 standard (2 m X 297 mm) is used. -23-丨 ^-ί (Please read the precautions on the back before filling out this page), 1T printed by the Ministry of Economy Central Standard Falcon Bureau Employee Consumer Cooperative printed by the Ministry of Economic Affairs Central Standard Bureau Employee Consumer Cooperative.

Invention Instructions (2i) The side of the garbage bin The strength is also due to the safety guide functioning as a deformed regulatory part, so it can prevent the large deformation of the side wall of the waste bin, and the finger will not enter the cutting part from between the waste bin and the cutting part, so it is very safe. " At the same time, according to the crank shape that makes the safety guide concave in the middle, each time the dust bin is taken out and put in, the cutting chips accumulated inside can be flattened out; therefore, the failure cause of the cutting chips blocking the rotating blade can be eliminated, and It can improve the storage efficiency of cutting scraps in the trash.
