Description

  The present invention relates to an automatic excrement processing apparatus that can be used by a person such as a sick person or an elderly person who has difficulty in processing excrement by himself or herself in a bed or a wheelchair.

  Conventionally, as this kind of excrement automatic processing apparatus, for example, a receiving body having a recess that is attached to a crotch portion of a human body and receives excretion excreted from the human body, and a recess that communicates with the recess of the receiving body is received by the recess. A discharge pipe for discharging the excrement, and connecting the discharge pipe to a tank for storing the excrement, and conveying the excrement into the tank by suction of a suction pump (for example, a patent No. 3749097).

Japanese Patent No. 3749097

  By the way, in the above-mentioned conventional excrement automatic processing apparatus, excrement is transported by suction of the suction pump, so if the suction force is strong, it will pull the genital area, anus and surroundings, so it will be painful. There was a problem that it might accompany. In addition, if the excrement is hard, there is also a drawback that it is difficult to move the discharge tube and clogs easily.

  The present invention has been made in view of the above-mentioned problems, and while avoiding discomfort such as pain due to suction to the human body as much as possible when transporting excrement, excrement can move reliably in the discharge pipe. An object of the present invention is to provide an automatic excrement processing apparatus.

In order to achieve such an object, the excrement automatic processing apparatus of the present invention includes a receiver having a substantially U-shaped recess that is attached to a crotch portion of a human body and receives excretion excreted from the human body, and the receiver. In a waste excrement processing apparatus provided with a discharge pipe connected to a discharge port communicating with the recess of the discharge pipe for discharging excrement received in the recess, the excrement from the upstream side to the downstream side of the discharge pipe It is set as the structure provided with the press conveyance means which presses and conveys.

  Thereby, the excretion excreted in the concave portion of the receiving body is discharged from the discharge port through the discharge pipe, but the excrement is pressed and conveyed from the upstream side to the downstream side by the pressing and conveying means. . In this case, since it is transported by pressing, it is not necessary to use suction as in the prior art, so that it is possible to prevent the human body from feeling uncomfortable, such as pain due to suction, and to perform excretion comfortably. . In addition, since the excrement is pressed, the excrement can easily pass through the discharge pipe and is prevented from being clogged, and the excrement can reliably move through the discharge pipe.

And, the prior position of the outlet of the upper Symbol receiving body, and the cylindrical buffer portion having a space to retention by aggregating excrement so constructed that protrudes from the recess. Since the excrement can be collected to some extent in the buffer part, it becomes easier to guide the excrement to the discharge pipe, and the transport can be facilitated accordingly.

Also, the upper Symbol receiving body, and ejecting fluid toward the outlet of the receiving only the body has a configuration in which a jet guide nozzle for guiding excrement to the discharge port through the space of the tubular buffer. As the fluid, air, water, or the like is used. Thereby, since the excrement is pushed into the discharge port by the fluid ejected from the ejection guide nozzle, the excrement can be easily guided to the exhaust pipe, and the transport can be facilitated accordingly.

  Furthermore, if the receiver is a dedicated receiver to be worn in a posture in which a human body is seated on a chair, if necessary, the outlet of the receiver can be placed in a substantially vertical direction so that excrement in front of the outlet can fall. It is configured to open downward. As a result, the discharge port of the receiver is opened downward in a substantially vertical direction so that excrement can fall, so even if there is no suction pump, excrement falls by its own weight and enters the discharge pipe from the discharge port. To go. Therefore, the excrement can be easily guided to the discharge pipe, and the transport can be facilitated accordingly.

  In addition, if necessary, the discharge pipe is formed of a flexible member, and the pressing and conveying means is configured to press the discharge pipe to cause forced contraction of the discharge pipe and the pressing position. A plurality of pairs of pressing bodies that are separated and moved relative to the two positions of the separation positions where the discharge pipe is returned to its original state by its own elastic force are arranged in a row. A pressing drive unit that is alternately positioned at the two positions of the pressing position and the separating position is provided.

  As a result, the pressing drive unit sequentially positions each set of pressing bodies at two positions of the pressing position and the separation position. However, when the pressing body is positioned at the pressing position, the excrement moves downstream. It will be pushed. In other words, the operation of the pressing body that is alternately positioned at the two positions of the pressing position and the separation position is sequentially repeated from the upstream side to the downstream side pressing body, and thereby excrement is conveyed. For this reason, since excrement is conveyed mainly by pressing the excrement, the excrement can surely move in the discharge pipe, and a situation where the excrement is clogged is prevented. In this case, even if the excrement lump is large to a certain extent, it is divided and reduced by the pressing body, so that it is easy to pass through the discharge pipe and the clogging situation is surely prevented, and the conveyance is performed smoothly. .

  In this case, it is effective that the pressing and conveying means includes a forward drive unit that sequentially moves each pair of pressing bodies forward at the pressing position of the pressing bodies. Thereby, since the advance drive part moves the pressing body forward in the pressing position of the pressing body, the excrement is further transported to the downstream side by this operation, and the transport is performed reliably.

  Moreover, the said press body is comprised with the roller as needed. Since it is a roller, it can be pressed while rolling the discharge pipe, so the operation is smooth.

  According to the present invention, since the excrement can be conveyed by being pressed from the upstream side to the downstream side by the pressing and conveying means, it is not necessary to rely on the suction as in the prior art. It is possible to prevent an unpleasant sensation and to excrete comfortably. In addition, since the excrement is pressed, the excrement can easily pass through the discharge pipe and is prevented from being clogged, and the excrement can reliably move through the discharge pipe. Furthermore, since the suction pump is relatively large, if the suction pump is not provided, the apparatus can be reduced in size, and particularly effective when mounted on a wheelchair.

Hereinafter, an excrement automatic processing apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 1 to FIG. 4, this excrement automatic processing apparatus is dedicated for use on the human body lying down on a bed or the like, and excrement E that is attached to the crotch of the human body and excreted from the human body. A receiving body 1 having a receiving recess 2, a discharge pipe 20 communicating with the recess 2 of the receiving body 1 for discharging excrement E received by the recess 2, and from the upstream side to the downstream side of the discharge pipe 20 And pressing and conveying means 30 for pressing and conveying the excrement E.

Specifically, the receiver 1 is formed of a flexible member such as a resin, and is formed in a substantially U-shaped cross section that covers the pubic area and anus from the front side to the rear side of the crotch part of the human body. . A substantially U-shaped concave portion 2 for receiving the excrement E is formed inside the central portion of the receptacle 1, and the outer periphery is formed so as to be in close contact with the human body. The receptacle 1 is formed with a discharge port 3 for excrement E communicating with the recess 2. A cylindrical buffer portion 4 having a space for collecting and retaining the excrement E is provided in front of the discharge port 3 of the receptacle 1. In addition, since the receiver 1 of the present apparatus is mainly mounted on a human body lying on its side, the buffer unit 4 extends along a substantially horizontal direction so that the protruding portion from the receiver 1 faces downward and does not hit the lateral surface. The discharge port 3 is opened horizontally in the horizontal direction.

Further, an injection guide nozzle that injects water as a fluid through the space of the buffer part 4 toward the discharge port 3 of the receiver 1 and guides the excrement E to the discharge port 3 at the end of the receiver 1 on the anal side 5 is provided.
Further, a plurality of cleaning nozzles 6 for injecting water (warm water) toward the genital area and the anus are provided on the front and rear wall portions.
The injection guide nozzle 5 and the cleaning nozzle 6 are connected to a water storage tank 8 that stores water via a pipe 7. A water supply pump 9 that supplies water to the injection guide nozzle 5 and the cleaning nozzle 6 is provided in the middle of the pipe 7. Is provided. Reference numeral 10 denotes a manual open / close type valve interposed in the middle of the pipe 7, which is normally open. The water storage tank 8 is provided with a heater 11 for heating water. In addition, the receiving body 1 is provided with a check valve 12 for introducing outside air when the inside of the receiving body 1 becomes negative pressure. In the embodiment, the pipe 7 for the injection guide nozzle 5 and the cleaning nozzle 6 is shared, but a pipe for the injection guide nozzle 5 may be separately provided and water may be injected from a dedicated pump.

  The discharge pipe 20 is formed of a flexible member such as a resin, and normally forms a pipe having a substantially circular cross section, is shrunk by pressing, returns to its original state by releasing the pressure, and holds the pipe again. Has elastic force. One end of the discharge pipe 20 is connected to the discharge port 3 of the receptacle 1, and the other end of the discharge pipe 20 is connected to a discharge hose 22 that conveys excrement E through a detachable coupling 21. . The discharge hose 22 is connected to a waste tank 23 that stores the waste E.

A suction pump 24 (vacuum pump) is connected to the filth tank 23, and the sewage tank 23 sucks excrement E in the discharge pipe 20 and the discharge hose 22 through the filth tank 23 by the suction pump 24. The excrement E can be transported inside. However, the suction pump 24 is functioned as an auxiliary function when the pressure conveying means 30 is in operation, and the pressure conveying means 30 is mainly responsible for conveying the excrement E. That is, the suction pump 24 in the present embodiment is set to have a lower suction force than the conventional device when the receiver 1 is attached to the human body, and does not give discomfort such as pain to the human body. . Further, when the receiver 1 is removed from the human body and the interior of the receiver 1, the discharge pipe 20 and the discharge hose 22 is cleaned, the suction pump 24 is mainly operated. At this time, the suction force can be increased as in the conventional apparatus.
A manual open / close valve 25 is interposed on the other end side of the discharge pipe 20 and is normally open. When removing the coupling 21 and disconnecting it from the discharge hose 22, the valve 25 is closed. Furthermore, a deodorizer 26 such as a filter for purifying the exhaust from the suction pump 24 is connected to the suction pump 24.

As shown in FIGS. 3 and 4, the pressing and conveying means 30 presses the discharge pipe 20 to cause the discharge pipe 20 to be forcedly contracted, and is separated from the pressing position X and the discharge pipe 20. Is provided with a pair of pressing bodies 31 that can be relatively moved to two positions of a separation position Y where the elastic force is restored by its own elastic force. Specifically, the pressing body 31 includes a roller that is rotatably supported by the rod 32, and includes a fixed pressing body 31A and a movable pressing body 31B. The rod 32 of the fixed pressing body 31 </ b> A is supported by the support member 33, and the support member 33 is fixed to the block body 34. The movable pressing body 31B is supported by a support member 35, and the support member 35 is supported by the block body 34 so as to be slidable. Then, by the sliding movement of the movable pressing body 31B, the fixed pressing body 31A and the movable pressing body 31B hold the discharge pipe 20 together and press the discharge pipe 20 by the fixed pressing body 31A and the movable pressing body 31B. The pressing position X and the fixed pressing body 31 </ b> A and the movable pressing body 31 </ b> B are positioned at a separation position Y where they are separated from each other.
The press conveying means 30 is configured by arranging a plurality of sets (1 to n sets) of a pair of a fixed pressing body 31 </ b> A and a movable pressing body 31 </ b> B along the discharge pipe 20.

The pressing and conveying means 30 includes a pressing drive unit 40 that alternately positions each pair of pressing bodies 31 at two positions of the pressing position X and the separating position Y, respectively. Specifically, the pressing drive unit 40 includes a plurality of electric actuators 40a that advance and retract the support members 35 that support the movable pressing bodies 31B.
Further, the press conveying unit 30 includes a forward drive unit 41 that sequentially moves the pressing bodies 31 of the respective sets at the pressing position X of the pressing bodies 31 to the downstream side. Specifically, the forward drive unit 41 includes a plurality of electric actuators 41a that move the block bodies 34 that support the support member 33 of the fixed pressing body 31A and the support member 35 of the movable pressing body 31B back and forth.

  Next, a control system of the excrement automatic processing apparatus according to the present embodiment will be described. As shown in FIG. 1, reference numeral 50 denotes a control unit that performs various controls by functions of a computer CPU or the like. The receptacle 1 is provided with an excrement detection sensor 51 that detects the presence or absence of the excrement E. 53 is a liquid level sensor of the filth tank 23. Based on the detection of the excrement detection sensor 51 and the liquid level sensor 53, the control unit 50 drives the water supply pump 9, the suction pump 24, the pressing drive unit 40, and the forward drive unit 41 according to the procedure described later. Reference numeral 55 denotes an operation unit that sends the detection signal of the excrement detection sensor 51 to the control unit 50 and manually drives the water pump 9, the suction pump 24, the pressing drive unit 40, and the forward drive unit 41 individually. The signal can be sent.

  Therefore, the excrement automatic processing apparatus according to the embodiment of the present invention operates as follows. In a state where the receptacle 1 is attached to the crotch portion of the human body, the excrement detection sensor 51 detects the presence or absence of the excrement E. In the non-excretion state, since the excretion detection sensor 51 detects the absence of the excretion E, the device is in a stopped state.

  In this state, when the excrement detection sensor 51 detects the presence, the control unit 50 drives the water pump 9, the suction pump 24, the pressing drive unit 40, and the forward drive unit 41 at a predetermined timing. First, for example, water is jetted from the cleaning nozzle 6 to clean the human body, and the excrement E is collected in the space of the buffer unit 4 by this water. In this case, since the excrement E can be gathered to some extent by the buffer part 4, it becomes easy to guide the excrement E to the discharge pipe 20, and the subsequent conveyance can be made easier.

In addition, as shown in FIG. 2, since water is sprayed from the ejection guide nozzle 5 toward the discharge port 3 in the space of the buffer unit 4, the excrement E is pushed by the discharge port 3. It enters the discharge pipe 20. In this case, since the excrement E comes to be pushed into the discharge port 3, the excrement E can be easily guided to the discharge pipe 20, and the subsequent conveyance can be facilitated accordingly.
Furthermore, since there is also suction by the suction pump 24, the excrement E enters the discharge pipe 20 by this. In this case, since the suction by the suction pump 24 is set to be weaker than that of the conventional device, a situation in which the human body is uncomfortable such as pain is prevented.

  The excrement E that has entered the discharge pipe 20 is conveyed downstream by the pressing and conveying means 30. Specifically, as shown in FIGS. 3 and 4, first, the electric actuator 40 a on the upstream side of the pressing drive unit 40 is driven, whereby the movable pressing body 31 </ b> B moves to the fixed pressing body 31 </ b> A side and the pressing body 31. (I) is positioned from the separation position Y to the pressing position X (S11, S12). Thereby, the excrement E is pushed downstream. In this case, even if the feces lump of excrement E is large to a certain extent, it is divided by the pressing body 31 and becomes small, so that it becomes easy to pass through the discharge pipe 20 and is reliably prevented from being clogged, and the conveyance is performed smoothly. It is.

  Next, at the pressing position X of the pressing body 31 (i), the electric actuator 41a on the upstream side of the forward drive unit 41 is operated, and the pressing body 31 (i) is moved forward to the downstream side (S13, S14). Thereby, the excrement E is conveyed further downstream. Also in this case, since the pressing body 31 (i) is moved forward to move the excrement E, the transport is reliably performed. Moreover, since the pressing body 31 is comprised with the roller, since the discharge pipe 20 can be pressed while rolling, operation | movement becomes smooth. Furthermore, in this case, since the lump of excrement E is divided and reduced by the pressing body 31, it becomes easy to pass through the discharge pipe 20, and the clogging situation is surely prevented, and the conveyance is performed smoothly. . Then, since the upstream side of the pressing body 31 (i) has a negative pressure, the excrement E reserved next is also moved.

  Then, by driving the electric actuator 40a upstream of the pressing drive unit 40, the movable pressing body 31B is separated from the fixed pressing body 31A and the pressing body 31 (i) is positioned at the separation position Y, and the forward driving unit 41 is moved. The upstream electric actuator 41a is actuated, and the pressing body 31 (i) is moved upstream to return to the original position (S15, S16, S11). In synchronism with this, the electric actuator 40a on the downstream side of the pressing drive unit 40 is driven, whereby the movable pressing body 31B moves to the fixed pressing body 31A side, and the pressing body 31 (i + 1) is pressed. X is positioned (S15). Next, at the pressing position X of the pressing body 31 (i + 1), the one electric actuator 41a on the downstream side of the forward drive unit 41 is operated, and the pressing body 31 (i + 1) is moved forward to the downstream side (S16). Thereby, also in the one pressing body 31 of the one downstream side, the effect | action and effect similar to the above are show | played, and the excretion E is conveyed smoothly.

  In this way, the downstream pressing body 31 is sequentially operated in the same manner, and such an operation is repeatedly performed from the upstream side to the downstream pressing body 31, thereby excrement E. Is carried out. For this reason, since the excrement E is transported mainly by pressing the excrement E, the excrement E can surely move in the discharge pipe 20 and a situation of clogging is prevented. Moreover, since it is mainly transported by pressing, even when the suction pump 24 is operated, when the excrement E is transported, the human body can be excreted comfortably without any discomfort such as pain due to suction. It becomes like this.

  When the excrement detection sensor 51 detects that there is no excrement E, the controller 50 determines that the excrement E is no longer present in the recess 2 of the receptacle 1. Stops driving and enters a standby state. In this case, the excrement E remains in the discharge pipe 20 and the discharge hose 22 to some extent, but may be removed when not used, which will be described later.

  When the apparatus is not used, the receptacle 1 is removed from the human body. At that time, the suction pump 24 is driven while water is poured into the receptacle 1. In this case, the suction force of the suction pump 24 is increased. Thereby, the excrement E remaining in the discharge pipe 20 and the discharge hose 22 is accommodated in the filth tank 23 together with water, and the discharge pipe 20 and the discharge hose 22 are cleaned.

  5 and 6 show another pressing and conveying means 30 of the excrement automatic processing apparatus according to the embodiment of the present invention. Unlike the above, this does not include the forward drive unit 41 that moves the pressing body 31 forward. That is, the pressing and conveying means 30 presses the discharge pipe 20 to cause forced contraction of the discharge pipe 20 and is separated from the press position X by using the discharge pipe 20 by its own elastic force. A fixed pressing body 31A and a movable pressing body 31B that are relatively movable are provided at two positions of the separation position Y to be returned. A plurality of sets of a pair of fixed pressing bodies 31 </ b> A and movable pressing bodies 31 </ b> B are arranged along the discharge pipe 20. Further, the pressing and conveying means 30 includes a pressing drive unit 40 similar to the above that alternately positions each pair of pressing bodies 31 at two positions of the pressing position X and the separating position Y, respectively.

  Therefore, according to the pressing and conveying means 30, the excrement E that has entered the discharge pipe 20 is conveyed downstream by the pressing and conveying means 30. Specifically, as shown in FIG. 6, first, the electric actuator 40a on the upstream side of the pressing drive unit 40 is driven, whereby the movable pressing body 31B moves to the fixed pressing body 31A side and is positioned at the pressing position X. (S21, S22). Thereby, the excrement E is pushed downstream. In this case, even if the feces lump of excrement E is large to a certain extent, it is divided by the pressing body 31 and becomes small, so that it becomes easy to pass through the discharge pipe 20 and is reliably prevented from being clogged, and the conveyance is performed smoothly. It is.

  Next, the electric actuator 40a on the downstream side of the pressing drive unit 40 is driven, whereby the movable pressing body 31B moves to the fixed pressing body 31A side and is positioned at the pressing position X (S23, S24). Thereby, the excrement E is pushed downstream. In this case, even if the feces lump of excrement E is large to a certain extent, it is divided by the pressing body 31 and becomes small, so that it becomes easy to pass through the discharge pipe 20 and is reliably prevented from being clogged, and the conveyance is performed smoothly. It is. In synchronism with this, the movable pressing body 31B is separated from the fixed pressing body 31A by the driving of the electric actuator 40a upstream of the pressing drive section 40, and is moved to the separated position Y and returned to the original position ( S24). In this case, since the downstream side of the pressing body 31 has a negative pressure, the next excrement E is also moved.

  Next, the pressing body 31 further downstream of the pressing drive unit 40 and the pressing body 31 further downstream are also moved and positioned at the pressing position X (S24, S25). ). In this way, the downstream pressing body 31 is sequentially operated in the same manner, and such an operation is repeatedly performed from the upstream side to the downstream pressing body 31, thereby excrement E. Is carried out. For this reason, since the excrement E is transported mainly by pressing the excrement E, the excrement E can surely move in the discharge pipe 20 and a situation of clogging is prevented. Moreover, since it is mainly transported by pressing, even when the suction pump 24 is operated, when the excrement E is transported, the human body can be excreted comfortably without any discomfort such as pain due to suction. It becomes like this.

7 and 8 show an excrement automatic processing apparatus according to another embodiment of the present invention. This excrement automatic processing apparatus is dedicated to use in a state where the human body is mounted on a wheelchair and a human body is sitting on a chair, and the receiver 1 is a dedicated receiver to be mounted in a posture where the human body is sitting on the chair. It is. This excrement automatic processing apparatus is configured in substantially the same manner as described above except for a part. Here, different configurations will be described.
The structure of the receiver 1 is substantially the same as described above, but in use, the buffer 4 of the receiver 1 protrudes along a substantially vertical direction, and the outlet 3 of the receiver 1 is located at the front of the outlet 3. The excrement E is opened downward in a substantially vertical direction so that it can fall. Further, one end of the discharge pipe 20 is connected to the discharge port 3, and a portion where the press conveying means 30 is located from this connection portion is arranged along the vertical direction. Unlike the above, the discharge hose 22 and the waste tank 23 are not connected to the other end of the discharge pipe 20. Further, the suction pump 24 is not mounted. However, a coupling 21 for connecting to the discharge hose 22 and the waste tank 23 is provided. A manual open / close valve 25 is interposed at the other end of the discharge pipe 20 and is normally closed. When the coupling 21 is connected to the discharge hose 22 and the waste tank 23, the valve is opened. The press conveying means 30 has the configuration shown in FIG. 3 or the configuration shown in FIG.

  Next, a control system of the excrement automatic processing apparatus according to the present embodiment will be described. As shown in FIG. 7, the receiver 1 is provided with a waste detection sensor 51 that detects the presence or absence of the waste E. Reference numeral 55 denotes an operation unit, which functions as a control unit that automatically drives the press conveyance means 30 based on detection by the excretion detection sensor 51. Moreover, the operation part 55 operates the water pump 9 manually suitably. Moreover, the press conveyance means 30 can also be driven manually.

  Therefore, the excrement automatic processing apparatus according to another embodiment of the present invention operates as follows. In a state where the receptacle 1 is attached to the crotch portion of the human body, the excrement detection sensor 51 detects the presence or absence of the excrement E. In the non-excretion state, since the excretion detection sensor 51 detects the absence of the excretion E, the device is in a stopped state.

  In this state, when the excrement detection sensor 51 detects the presence, the operation unit 55 drives the pressing and conveying means 30. The water pump 9 is manually operated as appropriate. When the excrement E is gathered in the space of the buffer part 4, as shown in FIG. 8, the buffer part 4 of the receptacle 1 protrudes along the substantially vertical direction, and the outlet 3 of the receptacle 1 is this outlet. 3 is opened downward in a substantially vertical direction so that the excrement E can be dropped, and the discharge pipe 20 has a vertical axis extending from the connection portion of the discharge port 3 to the portion where the pressure conveying means 30 is located. Therefore, even if there is no suction pump 24, the excrement E falls due to its own weight and enters the discharge pipe 20 from the discharge port 3. If the water pump 9 is manually operated, water is jetted from the cleaning nozzle 6 to clean the human body, and the excrement E is easily collected in the space of the buffer unit 4 by this water. In addition, since water is jetted from the jet guide nozzle 5 toward the discharge port 3 in the space of the buffer unit 4, the excrement E is pushed by the discharge port 3 and easily enters the discharge pipe 20. The excrement E that has entered the discharge pipe 20 is transported downstream by the press transport means 30 in the same manner as described above. In this case, since the suction pump 24 is not provided, the human body can be excreted comfortably without any discomfort such as pain due to suction.

  And when the excrement detection sensor 51 detects absence, the press conveyance means 30 will stop and it will be in a standby state, assuming that the excrement E is lose | eliminated in the recessed part 2 of the receptacle 1. FIG. The excrement E remains in the discharge pipe 20 and is stored. And when not using this apparatus, the receptacle 1 is removed from a human body. In that case, it connects with the waste tank 23 provided with the discharge hose 22 and the suction pump 24 similar to the above via the coupling 21, the valve 25 of a manual opening / closing type | mold is opened, and the recessed part 2 of the receptacle 1 is opened. The suction pump 24 is driven while supplying water. Thereby, the excrement E remaining in the discharge pipe 20 is accommodated in the filth tank 23 together with the water, and the discharge pipe 20 is cleaned.

  In the excrement automatic processing apparatus according to the above-described embodiment, the configuration of the pressing and conveying means 30 is not limited to the above-described one, and may be changed as appropriate. For example, as shown in FIG. 9, the rod of the movable pressing body 31B made of a roller can be eccentrically moved with respect to the fixed pressing body 31A, and the functions of both the pressing drive unit 40 and the forward driving unit 41 can be performed simultaneously. The driving mechanism 60 may be used for appropriate changes, such as a configuration.
