Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention relates to a vibrating device, and particularly to a vibrating device applied to various devices, equipment, etc. using a transformer.

(Prior Art) A conventional vibrating device is configured by, for example, connecting a component to be vibrated to a rotational drive source such as a motor via a gear device, a link device, or the like.

The rotary drive source can also be used as a drive source for various devices, equipment, etc. to which the vibration device is applied, or by providing a new drive source that is completely independent from the drive source.
It has been obtained.

In other words, the conventional vibrating device generates a rotary motion composed of a rotary drive source such as a motor, a gear device, a link device, etc.
A reciprocating motion conversion device is provided.

However, the use of the rotary motion-to-reciprocating motion converter makes the conventional vibrating device complicated in structure, increases production cost, and increases the number of failures.

Furthermore, as mentioned above, if the vibration device cannot be used as a drive source for various devices, equipment, etc. to which the vibration device is applied, a new drive source that is completely independent from the drive source must be provided. Therefore, there is a disadvantage that the production cost further increases.

(Objective) The present invention was made in order to eliminate the above-mentioned drawbacks, and its object is to generate vibration force without using a rotational drive source such as a motor and a rotational motion-reciprocating motion conversion device. The purpose of the present invention is to provide a vibrating device that can perform the following functions.

(Overview) In order to achieve the above object, the present invention provides a support that elastically supports a member to be vibrated with respect to a fixed member of a device to which the vibrator is applied and has a transformer; The vibrating device is characterized in that the vibrating device is constituted by a magnetic body fixed to the vibrating member so as to be able to vibrate in response to leakage magnetic flux from the device.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic sectional view of an embodiment of the present invention applied to a discharge tray 3 of an electronic copying machine, and FIG. 2 is a right side view of FIG. 1. In FIG. 2, the discharge roll 2 and the transformer 6 are omitted for clarity.

In the figure, an electrophotographic copying machine main body 1 has a paper discharge port 1A for discharging the recording paper 10 after copying. As is well known, a pair of discharge rolls 2 are arranged inside the paper discharge port 1A.

Further, a discharge tray 3 is provided at the lower end of the paper discharge port 1A.
A guide 1B is fixed to ensure that the recording paper 10 is ejected upward. The ejection tray 3 is attached to the electrophotographic copying machine main body 1 below the guide 1B by a rubber mount 4.
is elastically supported.

The support is arranged such that only one of the four corners of the bottom plate 3A of the output tray 3 is located at a lower position than the other three corners; that is, the bottom plate 3A is 1
Neither parallel to the transport direction of 0 nor! It is tilted around an imaginary axis that is not straight.

In FIG. 2, four corners 3C of the bottom plate 3A.

The corner portions on the backs of 3D, 3E, and 3F, indicated by the symbol @3C, are lower than the other three corner portions 3D, 3E, and 3F.

The recording paper 10 that has been copied is discharged onto the bottom plate 3A by the discharge roll 2, but since the bottom plate 3A is slanted as described above, the recording paper 10 is also ejected from its four corners. One of the corners will be sloped so that it is lower than the other three corners.

The rubber mount 4 used to support the discharge tray 3 is a joint having a rubber or rubber-like elastic support in its center. By using the rubber mount 4, the discharge tray 3 can swing by a predetermined angle around the center of the rubber mount 4.

A bracket 3B bent in a diagonal shape is fixed to the lower surface of the curved bottom plate 3A so as to correspond to the mounting position of the rubber mount 4. Further, a magnetic material 5 is provided on the surface of the bracket 3B facing the electrophotographic copying machine main body 1.
is fixed.

The transformer 6 is a power transformer provided to operate the electrophotographic copying machine. The transformer 6 includes at least a primary coil 6A, a secondary coil 6B, and an iron core 6C.

The transformer 6 is configured such that when an alternating current voltage is applied to the secondary coil 6A, leakage magnetic flux from the iron core 6C has the strongest influence on the magnetic body 5. In other words, the magnetic body 5 is arranged within the electrophotographic copying machine main body 1 so that it can be most strongly attracted by the leakage magnetic flux.

In FIG. 1, the iron core 6C is depicted as a rod-shaped body for convenience, so the transformer 6 is arranged so that the end of the iron core 6C faces the magnetic body 5.

However, the iron core 6C is generally designed in an annular shape to reduce leakage magnetic flux (so that the magnetic flux forms a closed magnetic path).

Therefore, it is desirable that the transformer 6 be arranged so that the leakage flux generated from the iron core 6C has the strongest influence on the magnetic body 5.

Furthermore, if a notch or the like is provided in the annularly formed iron core 6C, the leakage magnetic flux can be increased, so that it can have an even stronger influence on the magnetic body 5.

In one embodiment of the present invention having the above configuration, when the main switch of the electrophotographic copying machine is turned on and an alternating current voltage is applied to the negative side coil 6A, an alternating leakage magnetic flux is generated from both ends of the iron core 6C. . The magnetic body 5 is attracted every time leakage magnetic flux is generated from the iron core 6C, and thereby the discharge tray 3 vibrates in the direction of arrow A.

One of the four corners of the plurality of recording sheets 10 discharged onto the bottom plate 3A of the discharge tray 3 concentrates on the corner 3C of the bottom plate 3A due to the vibration, and as a result,
All four corners of the recording paper 10 are aligned.

Now, in the above description, the ejection tray 3 was assumed to be elastically supported with respect to the electrophotographic copying machine main body 1 by the rubber mount 4, but the present invention is not particularly limited to this.

That is, the ejection tray 3 is connected to the electrophotographic copying machine main body 1 by a hinge so that the ejection tray 3 can rotate in the direction of the arrow, and is further connected to the hinge of the ejection tray 3. The other side may be biased upward using a spring means or the like.

Furthermore, although the magnetic body 5 has been described as being fixed to the ejection tray 3 via the bracket 3B, the rubber mount 4 or the hinge and spring means may be arranged above the back plate 3G of the ejection tray 3. If possible, it goes without saying that it may be directly fixed to the lower part of the back plate 3G.

The ejection tray 3 vibrates from when the main switch of the electrophotographic copying machine is turned on until it is turned off.

However, for example, if it is possible to move the magnetic body 5 to a position where it is not affected by leakage magnetic flux from the transformer 6, it is possible to prevent the discharge tray 3 from vibrating even when the main switch is on. can do.

Alternatively, the same effect can be obtained by disposing a magnetic shield between the magnetic body 5 and the transformer 6 so that it can be inserted and removed.

The means for moving the magnetic body 5 and the means for removably arranging the magnetic shield can be easily implemented using known techniques, so a description thereof will be omitted.

In addition, although 5 was explained as being a mere magnetic material,
If a permanent magnet is used, it is possible to obtain a repulsive force in addition to the attractive force due to the leakage magnetic flux from the transformer 6, so that the ejection tray 3 can be photographed efficiently.

Furthermore, the vibration device should be set so that the natural frequency of the system including the discharge tray 3, rubber mount 4, bracket 3B, and magnetic body 5 matches the frequency of the AC voltage applied to the secondary coil 6A. For example, the discharge tray 3 resonates, and the vibration can be performed more efficiently.

Now, in the embodiment of the present invention as described above, the ejection tray 3 is vibrated around the rubber mount 4, but the present invention can only vibrate the parts to be vibrated around a certain fulcrum. Instead, it is also possible to oscillate the parts without the fulcrum, i.e. in parallel.

In other words, if a guide is provided that allows the part to be moved in parallel, and the part is elastically supported using a spring or the like on a fixed member to which the vibration technique W is applied, the part can be moved in parallel. Parallel vibration can be realized.

Further, although the above embodiment is applied to the ejection tray 3 of an electrophotographic copying machine, the electrophotographic copying machine may also include a 1-ner supply device, a cleaning device, or an electrophotographic copying machine having a double-sided copying function. In a copying machine, the present invention can also be applied to a paper storage unit or the like in which recording paper is temporarily stocked after front side copying is completed.

That is, for the toner supply device, a pair of plate-shaped bodies with a plurality of small holes are arranged on the bottom surface of the toner box instead of the toner supply roll, and the pair of plate-shaped bodies are arranged in opposite directions to each other, or By vibrating one of the plate-like bodies by the alternating leakage magnetic flux of the transformer 6, and supplying the toner into the developing device when the small holes formed in each plate-like body coincide with each other, can be applied.

For cleaning devices, it can be applied to blade oscillation (vibration of the cleaning blade in the generatrix direction of the photoreceptor).

In addition, in an electrophotographic copying machine having a double-sided copying function, a paper storage section that temporarily stores recording paper after the front side copy is completed stores the recording paper in a pair parallel to the conveyance direction to the back side copy of the recording paper. Since it is sufficient that the side edges of the recording paper can be aligned, at least one pair of guides that come into contact with the pair of side edges of the recording paper are arranged in the paper storage section, and the pair of guides are arranged in opposite directions. This can be applied by vibrating the recording paper in the direction to align the side edges of the recording paper.

Furthermore, the present invention is not limited in application to various devices such as electrophotographic copying machines, but can also be applied to household electrical appliances, industrial machines, etc. as long as the transformer 6 is included. It can be used in a wide range of applications.

(Effects) As is clear from the above description, according to the present invention, the following effects are achieved.

(1) Since the leakage magnetic flux of the transformer of various devices, equipment, etc. to which the vibration device is applied is used as the vibration drive source, the vibration device can be manufactured at low cost.

(2) Since a complicated link device and/or gear device is not used, the structure can be extremely simplified and failures can be reduced.
