本発明は一対のプーリ間へ掛け渡した駆動長尺体で走査
ヘッドを案内駆動する走査ヘッド案内構造に関する。Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a scanning head guide structure in which a scanning head is guided and driven by an elongated drive body stretched between a pair of pulleys.

４７号）。As a structure for guiding the scanning head for image exposure, the scanning head for printing, etc., a wire is stretched between a pair of pulleys.
In some configurations, this wire is attached to a scanning head to move the scanning head along a guide shaft. This scanning head guide structure can be used, for example, as a scanning head of an image recording apparatus that exposes an image onto a photosensitive material using an LED (for example, Japanese Patent Laid-Open No. 5'J-752
No. 47).
この走査ヘッド案内構造では、ワイヤを巻掛けるプーリ
の精度のばらつきによって、走査ヘッドがガイドシャフ
トから離れる方向にワイヤ張力の分力が働くことがあり
、露光時の焦点がずれる可能性がある。In this scanning head guide structure, due to variations in the precision of the pulley around which the wire is wound, a component of the wire tension may act in a direction in which the scanning head moves away from the guide shaft, which may cause a shift in focus during exposure.

せることがなく、走査ヘッドを安定して案内することが
できる走査ヘッド案内構造を得ることが目的である。The present invention takes the above-mentioned facts into account, and even when attaching a long driving body such as a wire stretched between pulleys to the scanning head, the present invention does not apply force in the direction away from the guide shaft to the scanning head. The objective is to obtain a scanning head guiding structure that can stably guide the scanning head.
本発明に係る走査ヘッド案内構造では、一対のプーリ間
へ掛け渡された長尺体は走査ヘッドが係止されないフリ
ー状態からオフセットした状態で走査ヘッドが取付けら
れるようになっている。In the scanning head guide structure according to the present invention, the scanning head is attached in a state where the long body spanned between the pair of pulleys is offset from the free state in which the scanning head is not locked.

。When the scanning head moves along the guide shaft,
Since the elongate body exerts a force on the scanning head in the direction toward the guide shaft, the scanning head is always moved while being pressed against the guide shaft during movement. Therefore, during movement, the scanning head will not be lifted off the guide shaft and will not cause errors in exposure work, printing work, etc.

The rotating drum 20 is rotated in the main scanning direction (in the direction of arrow A) by a driving means (not shown).On the other hand, the exposure head 22 has a sleeve 44 fitted onto a guide shaft 46, and rotates along the guide shaft 46 in the sub-scanning direction. However, this sleeve 44 allows the exposure head 22 to rotate around the axis of the guide shaft 46 (in the direction of arrow C) to facilitate repair of the exposure head 22. The guide shaft 46 is arranged so that its axis is parallel to the axis of the rotating drum 20.

されている。The exposure drum 22 is arranged as shown in FIG.
It has a block shape with a length of about 1/4 arc along the outer periphery, and three light emitting elements 48 are attached to it, and it emits three primary colors by a signal generating means (not shown), and is wound around the rotating drum 20. An image can be exposed onto the emulsion surface of the photosensitive material 16. The exposure head 22 has a slide metal 5 on the opposite side of the part where the sleeve 44 is attached.
0 is attached and comes into contact with the guide shaft 52,
The amount of rotation in the direction opposite to the direction of arrow C is limited. This guide shaft 52 is arranged parallel to the axis of the rotating drum 20.

ている。Here, as shown in FIG. 1, the exposure head 2 of the wire 54
2, the wire 54 is simply wound around the pulleys 56 and 58, and the wire 54 is not secured to the exposure pad 22.The wire 54 is simply wound around the pulley 56, 58, and is offset by a length from the free winding position (shown by imaginary lines in FIG. 1). It has been installed. Therefore, this wire 54
applies a rotational force around the guide shaft 46 to the exposure head 22 in the direction opposite to the direction of arrow C, thereby generating a force that constantly presses the exposure head 22 against the guide shaft 52.
次に本実施例の作用を説明する。Next, the operation of this embodiment will be explained.

光素子４８で露光を開始する。The photosensitive material 16 pulled out from the magazine 14 is cut into a cutter 18.
After being cut and wound around the outer periphery of the rotating drum 20, the rotating drum 20 rotates at high speed, and the exposure head 22 starts exposing the light emitting element 48.
これと同時にプーリ５６．５８は露光ヘッド２２を副走

正確な露光が可能となる。In this case, since the exposure head 22 receives a force in the direction of contacting the guide shaft 52 by the wire 54 attached offset, the exposure head 22, the pulley 56 .
Due to manufacturing errors, assembly errors, etc. of 58, exposure to Rad22
does not rise from the guide shaft 52, and accurate exposure is always possible.

に、受像材料３２へこの現像された画像が転写される。The photosensitive material 16 exposed in this way is transferred to the scraper 2.
After being peeled off at step 4 and coated with water at a water coating section 26, it is superimposed on an image receiving material 32 at a developing transfer means 28. In the developing and transferring means 28, the photosensitive material 16 is heated and developed, and the developed image is transferred to the image receiving material 32.
既に水塗布部２６で感光材料１６へ水塗布が成されてい

廃棄ボックス３８へと廃棄され、乾燥装置４０によって
受像材料３２が乾燥された後に取出トレイ４２へと取出
される。Since water has already been applied to the photosensitive material 16 in the water application section 26, the transfer can be performed reliably. The photosensitive material 16 after the transfer is discarded into a waste box 38, and after the image receiving material 32 is dried by a drying device 40, it is taken out to a take-out tray 42.
なお本発明は上記実施例のような露光ヘッドに限らず、
インクジェットを走査移動させて印字用に用いる等の他
の走査ヘッドにも通用可能である。Note that the present invention is not limited to the exposure head as in the above embodiment.
It is also applicable to other scanning heads, such as those used for printing by scanning an inkjet.

て走査ヘッドへ取付ければよい。Further, in the above embodiment, the wire 54 is offset from the free state where it is wound around the pulleys 56 and 58, but the movement trajectory of the wire 54 is changed by a winding rod or the like between the pulleys 56 and 58. In such a case, the wire may be attached to the scanning head with the movement locus changed by these winding rods and offset from the free state in which the wire is not locked to the scanning head.
