本発明は、例えば電子計算機からの演算出力、情報出力

装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device that records, for example, calculation output, information output, image output, etc. from an electronic computer on a recording medium. The present invention relates to an electrophotographic recording device that performs writing.
レーザプリン外孔代書される従来の電子写真方式の情報
記録装置は、そのベースとなる技術が電子写真技術即ち

設計製造されるのが通例であった。又上述の技術的背量
以外に、この種の記録装置が、まだまだ高体で需要も小
さく従って生産数量も少なかったため複写機との共通化
が必須とされてきたこと、又、いわゆる複写機屋さんが
記録装置（プリンター）を設計、製造してきたという点
からも複写機の枠から抜は出せないものであった。その
ため複写機は原稿を読み取って記録するということから

シ従って感光体への露光は感光体の上方の面に行ない、
用紙への転写部は感光体の下方で行うことが通例である
。この時用紙はその記録面を上向きに排出されるので、
例えば１０ページの原稿を複写するとき、１ベージ目が
一番下に、１０ページ目が最上部になり、結果ならべか

ースダウン機構が要求されてきたが、上述の問題点が避
けられなかった。Conventional electrophotographic information recording devices that use laser printing for outer holes are based on electrophotographic technology, that is, RPC copying machine technology, and are designed and manufactured by modifying PPO copying machines. was the norm. In addition to the above-mentioned technical burden, this type of recording device is still expensive, demand is low, and production quantities are also small, so it has become essential to standardize it with copying machines. The fact that he had designed and manufactured recording devices (printers) made it impossible to extract them from the scope of copying machines. Therefore, since a copying machine reads and records a document, its mechanism is to place the document on the top of the device.Therefore, the photoconductor is exposed to the surface above the photoconductor.
The transfer section to the paper is usually performed below the photoreceptor. At this time, the paper is ejected with its recording side facing upwards, so
For example, when copying a 10-page document, the first page will be at the bottom, the 10th page will be at the top, and the resulting paper will need to be reshuffled.If the paper is ejected with the recording side facing down, the paper will be ejected face-down. The disadvantages of cigarettes would be eliminated, but in order to do so, paper passes would become complicated or expensive options would be required. As a recording device for an electronic computer, this face-down mechanism has been required because a large amount of output is performed at one time, but the above-mentioned problems were unavoidable.
さらに感光体の下方に転写部がある場合、ベーパージャ

雑化に伴うコストアンプ不可避であったシ、大きな重量
部が可動機構となっているため振動衝撃に対して画質が
劣化しやすいという欠陥も有していた。Furthermore, if there is a transfer section below the photoreceptor, an opening/closing mechanism on the main body is used to release the vapor jam in the event of a vapor jam. Moreover, as the mechanism became more complicated, costs were unavoidably increased, and since the large weight part was a movable mechanism, the image quality easily deteriorated due to vibration and impact.

内汚れを誘引することになり単純にこれを解決すること
は困難であった。If the transfer section were placed above the drum, it would simply be face-down, but the process from transfer to fixing is simply toner on the paper, and the paper is placed with the toner-attached surface facing downward. Conveying the paper causes scratches on the recording surface due to sagging of the paper, image deterioration due to toner falling, and dirt inside the machine, which is difficult to solve simply.

It is an object of the present invention to provide an electrophotographic information recording device that has improved reliability.

４０ｍ１Ｌφに押えることができた。FIG. 1 is a side view of an electrophotographic information recording apparatus according to an embodiment of the present invention. The overall structure is a cylindrical photosensitive drum 1
, a charging unit 2 for applying a surface potential to the photoreceptor 1;
an exposure means 3 consisting of a liquid crystal shutter array and generating an optical signal corresponding to recorded information to form an electrostatic layer image on the photoreceptor 1; a developing device 4 for making the latent image on the photoreceptor 1 visible; A transfer device 5 for transferring the developer on the photoconductor 1 onto recording paper, a cleaning device 6 for removing residual developer etc. on the photoconductor 1, a recording paper storage section 7, and supplying recording paper one sheet at a time. It is comprised of a pick-up roller 8, a fixing device 9 for fixing the transferred recording paper, a motor 10 that is a power source for the entire operation, and the like. Here, the photoreceptor 1 has a cylindrical shape with an outer diameter of 50M*φ, and is made of selenium (Be) or organic photoreceptor (oPc) on an aluminum tube.
etc. are coated. The charging section 2 is a contact charger using a conductive brush, and has a width of 10 mm and a height of 101 st.
Compared to a corona charger, the direct sound means 3 is very 1/1 type and is composed of a liquid crystal shutter array 11, a lamp serving as a light source (a fluorescent lamp 12 is used here), a light guide plate 13, and an imaging lens 15. It's compact. Note that 16 is a drive circuit for the liquid crystal shutter array 11. The developing device 4 is of a magnetic brush developing type using a magnetic roller 17 having a diameter of 18 mm, and the capacity of the toner storage section 18 is increased by utilizing the upper space. The transfer device 5 is of a belt transfer type using a conductive rubber belt 19, and since the recording paper is thrown onto this belt 19 after the transfer, it can also be used to convey the recording paper after the transfer. Therefore, there is no need for a separation mechanism between the photoreceptor 1 and the recording paper, and there is no need for a special paper conveyance mechanism. Furthermore, since a corona charger is not used together with the charging section 2, there is almost no ozone generation, and there is no need for a device or exhaust space for exhausting ozone.
Since the photoreceptor 1 and toner are not deteriorated by ozone, the size can be reduced and reliability can be improved. The cleaning device 6 performs cleaning with a fur brush 20, and the diameter of the fur brush 20 is 2 (lawφ.
The tip of the bristles is only in soft contact with the photoconductor 1, so the rotational load on the photoconductor 1 is very light.The fixing device 9 is a heat roller type, and the heat roller 21 has an outer diameter of 3Q"φ.
, the rubber roller 22 has an outer diameter of 20 mπφ, and by minimizing the heater capacity, the drive motor 10 has an output of 1
A 5-20W DC servo motor is used. This is because there is no need for a moving mechanism for the document table like in a copying machine, the photoconductor 1 and other various components are made as small as possible to reduce the load, and friction mechanisms such as blades are eliminated as much as possible to reduce the load. Because of this, the outer diameter of the motor 10 could be kept to 40 m1Lφ.
さらに、本構成の最大の特徴は、複写機の枠から逸脱し
、プリンターとしての機能、理想を追求したものであり
、露光部３が感光体１の下部に配置され、逆に転写装置
５が、感光体１の上記に配置されている。このような配
置にすることにより、記録紙収納部７は、装置上方斜め
に配置され、下方に水平に配置した従来の複写機の例よ
り設置時のスペース効率を向上させることができ、かつ
紙搬送径路がほぼ水平であり、その信頼性は高い、。Furthermore, the biggest feature of this configuration is that it deviates from the framework of a copying machine and pursues the functionality and ideals of a printer. , are arranged above the photoreceptor 1. With this arrangement, the recording paper storage section 7 is arranged diagonally above the device, making it possible to improve space efficiency during installation compared to the example of a conventional copying machine, which is arranged horizontally below. The conveyance path is almost horizontal, and its reliability is high.
また、感光体１上のトナー像は記録紙の下面に転写され
定着装［９から記録紙が排出されたとき記録紙下面に印
写された印字出力を得る即ち１０枚の出力は、１枚目が
１ページ目に１０枚目が１０ページ目になう、並ぺかえ
が不要で、このまｊでいわゆるフェースダウンの機能を
有している。Furthermore, the toner image on the photoreceptor 1 is transferred to the bottom surface of the recording paper, and when the recording paper is discharged from the fixing device [9], the print output printed on the bottom surface of the recording paper is obtained. The 10th page becomes the 10th page, so there is no need to rearrange the pages, and it has a so-called face-down function.
これを可能とした理由は、転写装置５に、導電性ゴムベ
ルト１９によるベルト転写方式を採用したため、転写と
同時に、記録紙はこの転写ベルト１９に貼りつくため、
転写後の紙の搬送時に記録紙がたれ下ることなく、転写
ベルト１４に貼シついたまま、定着装ｆ９に運ばれるか
らである。This is possible because the transfer device 5 uses a belt transfer method using a conductive rubber belt 19, and the recording paper sticks to the transfer belt 19 at the same time as the transfer.
This is because the recording paper does not hang down when the paper is transported after the transfer, and is transported to the fixing device f9 while remaining stuck to the transfer belt 14.

軽減がはかれ、全体装置の小型化に多大の効果をもたら
している。In this embodiment, only the mechanical part is symmetrical, but if we further supplement the power supply part and the electronic circuit part for driving this mechanism, we will discuss the reduction in power supply and charging due to the use of a low-output motor as the drive motor 10. The device 2 is connected to the contact banding machine 1%'t-
By adopting a transfer belt mechanism for the transfer device 5, the IK system requires about 10 Kvo'lt of power compared to a corona charger.
Since the power supply is required to be less than vOlt, the power supply can be reduced, which has a great effect on downsizing the entire device.

ものである。In this embodiment, the exposure section 3 is placed inside the photoreceptor 1, and the other configurations are based on the same concept as in FIG. 2, and in addition to the features described in the embodiment in FIG. This configuration uses a transparent photoreceptor 1, and charges and develops at the outer periphery, and exposes from the inner periphery. It was put to good use.

下に述べる数々の効果を有する。The present invention has been described above in detail based on embodiments, but the present invention has a transfer device disposed above a photoreceptor, and has a number of effects described below.
■ 記録出力が７エースダウンで得られる。■ Record output can be obtained with 7 aces down.
特別な機構を必要とせず、又、単純な紙搬送径路で即ち
信頼性の高い機構でフェースダウン出力が得られる。No special mechanism is required, and face-down output can be obtained with a simple paper conveyance path, that is, with a highly reliable mechanism.
■ 本体の開閉機構が単純化できる。■ The opening and closing mechanism of the main body can be simplified.
ペーパージャム時の対策として本体の開閉機構が複写機

ーナー装置などの主要部は固定し、転写部を中心に可動
部とすればよく、従来例に比し簡素化できる。A main body opening/closing mechanism is also used in copying machines as a countermeasure against paper jams, but since the recording paper is conveyed above the photoreceptor as in the present invention, it is sufficient to open and close this conveyance path. Therefore, it is clear from the figure that the main parts such as the photoreceptor, the developing device, and the cleaner device can be fixed, and the transfer part can be made into a movable part, which makes it simpler than the conventional example.
さらに、これにともなって、重量部が可動機構となって
いないため、耐振動性、耐衝撃性に秀れ信頼性が向上す
る。また低コスト化もはかれる。Furthermore, since the weight part is not a movable mechanism, vibration resistance and impact resistance are excellent, and reliability is improved. Also, cost reduction can be achieved.
