Description

本発明は、レーザビームプリンター等に用いられ、レーザビームを偏向走査するための偏向走査装置に関するものである。   The present invention relates to a deflection scanning device used in a laser beam printer or the like for deflecting and scanning a laser beam.

近年、この種の偏向走査装置では、印字の高速化と共に静粛性が求められている。この静粛性を損なう要因の1つとしてスキャナモータの駆動音が挙げられる。スキャナモータが引き起こす駆動音は主に光学多面鏡が回転時発生する、風切音の他に電機子巻線に電流を流す際に発生する積層コアの振動音が挙げられる。前述の積層コアの振動音は、モータ起動時の引き込み音、回転時の電磁音、低速時において発生するコギング音となり、前記積層コア組の振動がハウジング、実装基板、光学箱に伝わり、共振又は共鳴を起こす。この問題を回避するためには、振動体を他の部材と接触面積を必要最小限に留めること、或は、防振材を介して直接接触させないことが必要である。   In recent years, with this type of deflection scanning apparatus, there has been a demand for quietness as well as higher printing speed. One of the factors that impair this quietness is the driving sound of the scanner motor. The driving sound caused by the scanner motor is mainly generated when the optical polygon mirror is rotated. In addition to wind noise, vibration sound of the laminated core generated when current is passed through the armature winding can be cited. The vibration sound of the laminated core described above becomes a pull-in sound at the time of starting the motor, an electromagnetic sound at the time of rotation, and a cogging sound generated at a low speed. Cause resonance. In order to avoid this problem, it is necessary to keep the vibrating body in contact with the other members to the minimum necessary amount, or not to directly contact with the vibration isolator.

ここで、特許文献1に示される図6は、モータ振動が外部に伝搬して大きな振動騒音を引き起こすことを防止或は抑制可能なモータの取付機構を提案防止することを表わした図である。   Here, FIG. 6 shown in Patent Document 1 is a diagram showing the proposed prevention of a motor mounting mechanism that can prevent or suppress motor vibration from propagating to the outside to cause large vibration noise.

この構成において、モータ101のステータアセンブリ102の構成要素であるモータフレーム122は、その外周に形成した環状フランジ123が支持基板110の側に締結固定されている。支持基板110には、振動伝搬抑制部である、下方に開口したコ字状断面部分103が形成されている。支持基板110の外周側の部分がレンズユニット111のユニットケース112の側に締結固定されている。モータ101で発生した振動は、モータフレーム122及び支持基板110を介してレンズユニット111の側に伝播する。   In this configuration, a motor frame 122 that is a component of the stator assembly 102 of the motor 101 has an annular flange 123 formed on the outer periphery thereof fixed to the support substrate 110 side. The support substrate 110 is formed with a U-shaped cross-sectional portion 103 that opens downward and is a vibration propagation suppressing portion. The outer peripheral portion of the support substrate 110 is fastened and fixed to the unit case 112 side of the lens unit 111. Vibration generated by the motor 101 propagates to the lens unit 111 side through the motor frame 122 and the support substrate 110.

しかし、この伝播経路の途中にはコ字状断面部分103が形成されているので、この部分において、モータ振動、特にその縦波成分が吸収或は低減される。従って、モータ振動が外部部材であるレンズユニット111の側に伝播すること効果的に抑制或は防止できる。   However, since the U-shaped cross-sectional portion 103 is formed in the middle of this propagation path, motor vibration, particularly its longitudinal wave component, is absorbed or reduced in this portion. Therefore, it is possible to effectively suppress or prevent the motor vibration from propagating to the lens unit 111 which is an external member.

しかしながら、上記従来例では、以下のような課題がある。   However, the conventional example has the following problems.

1.振動の吸収できる方向がスラスト方向のみである。   1. The direction in which vibration can be absorbed is only the thrust direction.

2.積層コアからユニットケースまでの部品点数が多い。   2. There are many parts from the laminated core to the unit case.

3.この構成を用いるためにはモータ下部(ステータアセンブリ、モータフレーム)が特殊な形状を成すことを必要としている。   3. In order to use this configuration, the lower part of the motor (stator assembly, motor frame) needs to have a special shape.

このため、ラジアル方向の振動は吸収できず、部品点数が多くコスト的に割高となり、部品が特殊な形状であって混沌となり、汎用性に乏しい等の欠点があった。   For this reason, vibrations in the radial direction cannot be absorbed, the number of parts is large and the cost is high, the parts have a special shape and become chaotic, and there are disadvantages such as poor versatility.

本発明は上記従来の問題を解決するものであり、電機子巻線に電流を流す際に発生する積層コアの振動音の伝達を抑え、静粛性を備えた偏向走査装置を提供することを目的としている。   SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a deflection scanning device that suppresses transmission of vibration sound of a laminated core that is generated when an electric current is passed through an armature winding and has quietness. It is said.

上記目的を達成するため、請求項1記載の発明は、積層されたステータコアに電機子巻線が巻装されこの前記電機子巻線に励磁を行うために設けられた通電用ピンを備えた積層コア組を、軸受ハウジングを位置決め支承された実装基板に有し、前記軸受ハウジングを中心として前記積層コア組と径方向に対向する駆動用永久磁石を内側に有した回転可能な回転子であり、且つ、レーザ光を偏向するための回転多面鏡を備えた偏向走査装置において、前記積層コア組は、前記通電用ピンのみで、前記実装基板に固定されていることを特徴としている。尚、前記実装基板への通電用ピンの固定固定方法は、半田付けのみでも構わない。   In order to achieve the above object, an invention according to claim 1 is a laminate comprising an energizing pin provided for energizing an armature winding wound around a laminated stator core. A rotatable rotor having a core set on a mounting substrate on which a bearing housing is positioned and supported, and having a permanent magnet for driving opposed to the laminated core set in the radial direction around the bearing housing; In the deflection scanning apparatus provided with a rotating polygon mirror for deflecting the laser beam, the laminated core set is fixed to the mounting substrate only by the energizing pins. Note that the method of fixing and fixing the energizing pins to the mounting board may be only soldering.

上記構成においてモータの起動を行うと、電流を流す際に積層コア組の振動が発生する。しかしながら、電機子巻線に発生する積層コア組の振動は、通電用ピンのみで、前記実装基板に接合され接合面積が小さいため、振動の伝わりを最小限度に抑え、共振又は共鳴を防ぐことができる。   When the motor is started in the above configuration, the laminated core set vibrates when a current is passed. However, the vibration of the laminated core assembly generated in the armature winding is joined to the mounting board only by the energizing pins and has a small joint area, so that the transmission of vibration can be minimized and resonance or resonance can be prevented. it can.

又、積層コアと軸受けハウジングとの同軸は、同軸の取れた位置決め用中空のカラーを用いて行えば、回転子との同軸も取れ偏芯による電磁音そのものの発生も防ぐことが可能である。特に、別部材を使う必要がなく本構成のモータ組は、最も安価な偏向走査装置の提供が可能である。   Further, if the laminated core and the bearing housing are coaxial with each other by using a coaxial positioning hollow collar, it is possible to take the coaxial with the rotor and to prevent generation of electromagnetic sound due to eccentricity. In particular, it is not necessary to use a separate member, and the motor set having this configuration can provide the most inexpensive deflection scanning apparatus.

請求項2記載の発明は、前記電機子巻線に励磁を行うための通電用ピンを備えた前記積層コア組において、前記積層コア組は、防振部材を介して前記固定子又は実装基板に接合されていることを特徴とする。この構成によると、積層コア組から発生する振動は、防振部材を介して軸受けハウジング部又は実装基板に伝えられるため、振動が減衰し音の共振或は共鳴を大幅に減少させることが可能である。   According to a second aspect of the present invention, in the laminated core set provided with energization pins for exciting the armature winding, the laminated core set is attached to the stator or the mounting substrate via a vibration isolating member. It is characterized by being joined. According to this configuration, the vibration generated from the laminated core set is transmitted to the bearing housing portion or the mounting board via the vibration isolating member, so that the vibration is attenuated and the resonance or resonance of the sound can be greatly reduced. is there.

本発明によれば、振動源である積層コアの振動をスラスト、ラジアル方向の共に他の部材に伝えることなく、共振或は共鳴を防ぎ、光学偏向装置の共鳴を最小限に留めることが可能であり、又、構成部品が少なく、特に特殊な形状を持った部品を必要としないため、静粛性を備え、且つ、安価で汎用性の高い偏向走査装置を得ることができる。   According to the present invention, it is possible to prevent resonance or resonance and transmit resonance of the optical deflecting device to a minimum without transmitting the vibration of the laminated core as a vibration source to other members in both the thrust and radial directions. In addition, since there are few components and no special parts are required, it is possible to obtain a deflection scanning apparatus that is quiet, inexpensive, and highly versatile.

<実施の形態1>
図1は本発明の特徴を最も良く表す光偏向器の断面図であり、実装基板12上に積層コア組19が配置され、積層コア組19の内径近傍に電機子巻線18に励磁を行うために設けられた通電用ピン20を備えている。又、実装基板12には軸受ハウジング17が位置決め支承されている。積層コア組19と径方向に対向する位置に駆動用永久磁石24を有し、その外周をロータ28にて保持されたロータユニット4としてポリゴン座25に固定されている。又、前記ポリゴン座25には、レーザ光を偏向するための回転多面鏡3の内径がシャフト15と同軸が取られて嵌合しており、スラスト方向にウェーブワッシャ29によりポリゴン座25に押し付けられ、グリップリング30によってスラスト方向へ加圧保持されている。又、回転多面鏡3の回転保持を行っているシャフト29は、スラスト受け26によりスラスト方向の荷重を保持している。
<Embodiment 1>
FIG. 1 is a cross-sectional view of an optical deflector that best represents the features of the present invention. A laminated core set 19 is disposed on a mounting substrate 12 and an armature winding 18 is excited near the inner diameter of the laminated core set 19. For this purpose, an energizing pin 20 is provided. A bearing housing 17 is positioned and supported on the mounting board 12. A permanent magnet 24 for driving is provided at a position opposed to the laminated core set 19 in the radial direction, and the outer periphery thereof is fixed to the polygon seat 25 as the rotor unit 4 held by the rotor 28. Further, the polygonal face 25 is fitted with the inner diameter of the rotary polygon mirror 3 for deflecting the laser light so that it is coaxial with the shaft 15 and is pressed against the polygonal face 25 by the wave washer 29 in the thrust direction. The pressure is held in the thrust direction by the grip ring 30. In addition, the shaft 29 that holds the rotary polygon mirror 3 holds the load in the thrust direction by the thrust receiver 26.

この状態で実装基板12から積層コア組19に巻装されている電機子巻線18と接合されている通電用ピン20に電流を印加することにより、積層コア組19の外周部に磁場が集中し、この電流の印加を各位相に順次切り替えることによりロータユニット23の内側に固定された駆動用永久磁石24に回転力を与え、シャフト15を中心にロータユニット23及び回転多面鏡3が回転する。ここで、前記積層コア組19は、軸受けハウジング17の径方向ではΔr、高さ方向ではΔhの隙間を持ち、実装基板12とは、高さΔHの隙間を持っている。   In this state, a magnetic field is concentrated on the outer peripheral portion of the laminated core assembly 19 by applying a current from the mounting substrate 12 to the energizing pins 20 joined to the armature windings 18 wound around the laminated core assembly 19. Then, by sequentially switching the application of this current to each phase, a rotational force is applied to the driving permanent magnet 24 fixed inside the rotor unit 23, and the rotor unit 23 and the rotary polygon mirror 3 rotate around the shaft 15. . Here, the laminated core set 19 has a clearance Δr in the radial direction of the bearing housing 17 and a clearance Δh in the height direction, and a clearance ΔH from the mounting substrate 12.

次に、図2は前記隙間Δr,Δh,ΔHの説明を行う。図2では本発明のためロータユニット23を取り外した積層コア組19及びハウジング17の斜視断面図である。尚、図1と同じ部品で機能の同じものについては同一番号を符し説明を省略する。   Next, FIG. 2 explains the gaps Δr, Δh, and ΔH. FIG. 2 is a perspective sectional view of the laminated core set 19 and the housing 17 from which the rotor unit 23 is removed for the present invention. The same parts as in FIG. 1 having the same functions are denoted by the same reference numerals and description thereof is omitted.

ここで、A部詳細図に示される通り、前記積層コア組19は、通電ピン20のみにより実装基板12上の半田ランド27に半田付けで固定されており、軸受けハウジング17の径方向ではΔr、高さ方向ではΔhの隙間を持ち、実装基板12とは、高さΔHの隙間を持ち通電ピン20以外の部分で他の固定子とは接触していない。   Here, as shown in the A part detailed view, the laminated core set 19 is fixed by soldering to the solder lands 27 on the mounting substrate 12 only by the energizing pins 20, and in the radial direction of the bearing housing 17, Δr, There is a gap of Δh in the height direction, and the mounting substrate 12 has a gap of height ΔH and is not in contact with other stators at portions other than the energizing pins 20.

又、図3に示すように、同軸の取れた中空のカラー22を用いて積層コア組19と軸受けハウジング17との隙間に挿入し、積層コア組19を接合することにより、同軸をとることもでき、電磁音そのものの発生を抑えることが可能となる。   Further, as shown in FIG. 3, the hollow core 22 can be coaxially inserted into the gap between the laminated core set 19 and the bearing housing 17, and the laminated core set 19 can be joined to be coaxial. It is possible to suppress the generation of electromagnetic sound itself.

以上説明したように、積層コア組19が通電ピン20のみで実装基板12に接触しているため、起動時、定常回転時、停止時に発生する積層コア組19の振動の伝わりを実装基板12に伝えることなく、実装基板12の共振、共鳴を防ぐ効果があると共に、本発明は、部品点数を最小限度に抑えているため、最も安価な光偏向器を提供できる効果がある。   As described above, since the laminated core set 19 is in contact with the mounting board 12 only by the energization pins 20, the vibration of the laminated core set 19 generated at the time of starting, steady rotation, and stopping is transmitted to the mounting board 12. Without being transmitted, there is an effect of preventing resonance of the mounting substrate 12 and resonance, and the present invention has the effect of providing the most inexpensive optical deflector because the number of parts is minimized.

図4は本発明の実施の形態1の偏光器を用いた走査光学装置の斜視図であり、レーザユニット1からレーザ光Lが出射され、シリンドリカルレンズ2によって副走査方向のみ収束し、回転多面鏡3に照射し主走査方向に長く延びる焦線状に結像する。ここで、前記回転多面鏡3は、ビス13にて光学フレ−ム10に締結された光偏向器8上にあり、ロータユニット4と共に回転可能なシャフト15に固定されており、回転によりレーザ光が偏向可能な構成となっている。そして、回転多面鏡3の回転によって反射され偏向走査された光束は、fθレンズ7を通過した後、折り返しミラー14によって光路が折り返され、感光体ドラム11上に集光して一定速度で走査される。   FIG. 4 is a perspective view of a scanning optical device using the polarizer of Embodiment 1 of the present invention. Laser light L is emitted from the laser unit 1 and converged only in the sub-scanning direction by the cylindrical lens 2, and is a rotating polygon mirror. 3 is imaged in the form of a focal line extending in the main scanning direction. Here, the rotary polygon mirror 3 is on an optical deflector 8 fastened to an optical frame 10 with screws 13 and is fixed to a shaft 15 that can rotate together with the rotor unit 4. Can be deflected. Then, the light beam reflected and deflected and scanned by the rotation of the rotary polygon mirror 3 passes through the fθ lens 7, and then the optical path is folded by the folding mirror 14, condensed on the photosensitive drum 11, and scanned at a constant speed. The

又、レ−ザユニット1から出射されたレーザ光束は、回転多面鏡3で反射され、画像領域に入る前に同期検知用光学系(BDレンズ)5に入射し、同期検知器6で検知され、同期検知器6の検知信号から所定の遅延時間後を主走査方向の書き出し開始位置とする。このとき、本実施の形態に係る走査光学装置では、前記のように積層コア組19が通電ピン20のみで実装基板12に接触しているため、起動時、定常回転時、停止時に発生する積層コア組19の振動が、実装基板12、光学フレーム10へ伝わることを最小限度に抑えることが可能となり、共振、共鳴を防ぐ効果がある。   Further, the laser beam emitted from the laser unit 1 is reflected by the rotary polygon mirror 3, enters the synchronization detection optical system (BD lens) 5 before entering the image area, and is detected by the synchronization detector 6. The writing start position in the main scanning direction is set after a predetermined delay time from the detection signal of the synchronization detector 6. At this time, in the scanning optical device according to the present embodiment, since the laminated core set 19 is in contact with the mounting substrate 12 only by the energization pins 20 as described above, the lamination occurs at the time of start-up, steady rotation, and stop. It is possible to minimize the vibration of the core set 19 from being transmitted to the mounting substrate 12 and the optical frame 10, and there is an effect of preventing resonance and resonance.

<Embodiment 2>
FIG. 5 shows the laminated core set 19 provided with energizing pins 20 for exciting the armature winding 18. The laminated core set 19 is connected to the bearing housing 17 and the mounting substrate 10 via a vibration isolation member 21. It is the figure showing the deflection scanning device characterized by being fixed to. The same parts as in FIG. 1 having the same functions are denoted by the same reference numerals and description thereof is omitted.

本構成によると、積層コア組19に発生する振動は防振部材21により吸収され、軸受けハウジング17、実装基板10、光学フレーム12に伝わる量が軽減されるため、モータ起動時、定常回転時、停止時に発生する積層コア組19の振動の伝わりを最小限度に抑えて共振及び共鳴を防ぐことができる。尚、防振材21を入れる箇所は、特に軸受けハウジング17及び実装基板12を含む固定子のスラスト方向又はラジアル方向の何れか一方のみでも良い。又、本実施の形態で挙げる防振部材21とは、部材に限ったものではなく、硬化後弾性を持った接着剤等の補材を充填しても構わない。   According to this configuration, vibration generated in the laminated core set 19 is absorbed by the vibration isolation member 21, and the amount transmitted to the bearing housing 17, the mounting substrate 10, and the optical frame 12 is reduced. Resonance and resonance can be prevented by minimizing the transmission of vibration of the laminated core set 19 that occurs at the time of stopping. Note that the place where the vibration isolator 21 is inserted may be only one of the thrust direction and the radial direction of the stator including the bearing housing 17 and the mounting substrate 12. Further, the vibration isolating member 21 mentioned in the present embodiment is not limited to a member, and may be filled with an auxiliary material such as an adhesive having elasticity after curing.

本発明によると、振動の伝わりを抑えることが可能となり共振、共鳴を防ぐことができると同時に、防振部材を介して位置決め固定されているため、組付作業の簡素化が可能であり、且つ、ばらつきの少ない安定した製品の供給を行える効果がある。   According to the present invention, it is possible to suppress the transmission of vibrations and prevent resonance and resonance, and at the same time, the positioning is fixed through the vibration isolating member, so that the assembly work can be simplified, and This has the effect of supplying a stable product with little variation.

本発明は、レーザビームプリンター等においてレーザビームを偏向走査するための偏向走査装置に対して適用可能である。   The present invention is applicable to a deflection scanning apparatus for deflecting and scanning a laser beam in a laser beam printer or the like.
