In the figure, (1) to (4) and (6) to (8) have substantially the same structure as the conventional floor brush. Reference numeral (9) is a rectangular bearing device that rotatably holds the tip of the shaft (3a) of the rotating brush (3), and has a bearing hole (9a) into which the tip is inserted. Reference numeral (10) is a guide tube that surrounds the bearing device (9) so as to contact both side surfaces and a back surface of the bearing device (9) and guides the bearing device (9) in a vertically slidable manner. Is molded,
The upper part is slightly inclined rearward to form an arc with respect to the axis (2a). (10a) is a dust-proof rubber sheet adhered to the upper surface of the guide cylinder (10) and has an opening in the center. (11) is a spring whose one end is fixed to the bottom surface of the guide cylinder (10) and the other end is in contact with the lower surface (9b) of the bearing device (9), and (12) is an upper part of the bearing device (9). This is an electromagnetic device provided, and the movable body (12a) is brought into contact with the upper surface (9c) of the bearing device (9) through the opening of the rubber sheet (10a). The guide cylinder (10), the spring (11), and the electromagnetic device (12) are collectively referred to as a shaft moving device. Reference numeral (13) is a detection device for detecting the state of the floor surface provided over the front and rear of the bearing device (9), and the front side is a sound wave generation device (13
a) and the sound wave receiving device (13b) on the rear side. Reference numeral (14) is a control device built in the rear portion of the floor brush main body (1), which receives an input from the detection device (13) and controls the electromagnetic device (12) and the electric motor (2). (15) is a dutan, (16) is a step, and (17) is between boards.

First, an electric vacuum cleaner (not shown) is activated to generate intake air through the suction port (6), and a hand switch provided on a dust collecting hose (not shown) is operated to control the power control device shown in FIG. 2) Start up.

スペースが空き，塵埃の吸込が良好になる。As shown in FIG. 3, the rotating brush (3) guides the dust to the suction port (6) while wiping the dust on the guest (15) at the normal position A. Next, as shown in Fig. 4, when the step is reached at the boundary between the board and the board, the distance between the floor brush body (1) and the floor surface increases, and the sound wave generator (13a) reflects on the floor surface. The amount of reception that the sound wave receiving device (13b) receives is weakened. The control device (14) reads this difference and outputs it to the electromagnetic device (12). The electromagnetic device (12) receives this output and pushes out the movable body (12a). Since the movable body (12a) is pushed out, the bearing device (9) is pushed downward against the elastic force of the spring (11). As a result, the rotary brush (3) is lowered from the normal position A to the lower position B, and the step (1
6) Wipe off the dust that has stuck to. After that, when the floor brush main body (1) is moved as shown in FIG. 5, this time the sound wave generator (13a) reflects the sound wave between the plates (17) and causes the sound wave receiver (13b) to receive it. The control device (14) reads the reception rate of sound waves, stops the electric motor (2), retracts the movable body (12a), and pushes up the axial drawing device (9) to information by the elasticity of the spring (11). . As a result, the rotary brush (3) is raised from the lower position B to the upper position C, so that the space between the opening (1a) and the suction port (6) is vacant and the suction of dust becomes good.

床ブラシ本体（１）を移動させれば，音波発生装置（13

る。Further, again, as shown in FIG. 3, if the floor brush body (1) is moved onto the guest (15), the sound wave generator (13)
In the case of a), the sound wave is reflected by the guest (15) and is received by the sound wave receiving device (13b), so that the sound wave reception rate is deteriorated.
The controller (14) reads this difference, starts the electric motor (2), and outputs it to the electromagnetic device (12) to output the movable body (12).
a) is extruded almost half. This allows the bearing device (9)
The rotating brush (3) returns from the upper position C to the normal position A and wipes the surface of the duster (15) while sending dust to the suction port (6), so that the floor surface can be thoroughly cleaned.
なお床ブラシ本体（１）を持ち上げた際は，音波受信
装置（13b）は全く受信出来なくなり，制御装置（14）
はこれを読みとり電動機（２）を停止させる。When the floor brush body (1) is lifted, the sound wave receiving device (13b) cannot receive any sound, and the control device (14)
Reads this and stops the electric motor (2).

すればしつこいごみを取ることが出来る。Further, in the above embodiment, the electromagnetic device (12) is controlled by the detection device (13), but the control device (14) is made to detect the ON / OFF of the electric motor (2), and the electromagnetic device is responded accordingly. (12) may be controlled, or as shown in FIG. 7, a dust collection hose is provided with a remote control device (18) so that it can be operated independently. When picking up stuck dust, you can remove persistent dust by lowering the rotating brush (3) and pressing it against the surface of the youtan (15).
また集塵用ホースに遠隔操作装置（18）を設けたの
で，手元で，回転ブラシ（３）を操作出来て便利であ
る。Moreover, since the dust collection hose is provided with the remote control device (18), it is convenient to operate the rotating brush (3) at hand.

い。Further, in the above-mentioned embodiment, the sound wave generator (13a) and the sound wave receiver (13b) are used as the detection device (13).
By using the light emitting element and the light receiving element disclosed in the publication No. 21795,
You may make it read the difference of the reflectance to the floor surface.
Alternatively, a micro switch having an actuator may be brought into contact with the floor surface to open and close the circuit by the ups and downs of the actuator. That is, as shown in FIG. 8 and FIG. 9, the actuator is sunk into the hair of the dutan (15) to close the circuit at the time of the duty (15), and floats to open the circuit between the boards and the tatami mat. It is a thing. When a control pattern that does not detect the presence or absence of driving of the electric motor (2) is performed, a fan is arranged in the suction port (6), and this fan is rotated by the intake air, and the rotational force of this fan is transferred to the belt ( The drive device may be a so-called conventional turbine that is transmitted to the rotating brush (3) via 4).
また検知装置（３）を軸受装置（９）の前後に設けた
ので、回転ブラシ（３）の垂下と，発光装置（13a）の
反射面とが同一線上となり，適切な検知を行うことが出
来る。Further, since the detection device (3) is provided before and after the bearing device (9), the hanging of the rotating brush (3) and the reflection surface of the light emitting device (13a) are on the same line, and proper detection can be performed. .
また上記実施例では軸受装置（９）を上下させるため
に電磁装置（12）を用いて，電気的に移動させるように
構成したが，機械的構造によつて手動で操作させるよう
にしてもよいことはいうまでもない。Further, in the above embodiment, the electromagnetic device (12) is used to move the bearing device (9) up and down, and the bearing device (9) is electrically moved. However, it may be manually operated by a mechanical structure. Needless to say.
また，軸受装置（９）は下方からはスプリング（11）
により，上方からは電磁装置（12）により，弾性的に固
定されるので，下方から強い衝撃を受けても弾性により
力を吸収してしまい，軸受装置（９）に衝撃が伝わらな
い。Further, the bearing device (9) has a spring (11) from below.
As a result, since it is elastically fixed from above by the electromagnetic device (12), even if a strong impact is applied from below, the force is absorbed by the elasticity and the impact is not transmitted to the bearing device (9).

来るものである。Also, when cleaning a high-haired jyutan (15) such as the sheaju's jyutan (15), the floor brush sinks under the jyutan (15), increasing the frictional resistance between the rotating brush (3) and the jyutan. , Load is applied to the electric motor (2), but at this time, since the rotating brush (3) is supported by the electromagnetic device (12), it escapes slightly above the normal position A,
The load is not applied to the electric motor (2), and the frictional resistance of the rotating brush (3) is reduced, so that good cleaning can be performed.
また電磁装置（12），電動機（２），検知装置（13）

Any control pattern may be configured by
When the rotary brush (13) is moved to the lower position C by the electromagnetic device (12), the electric motor (2) may be operated at a low speed or may be reversed.
