Description

上記の課題を解決するため、本発明に係る画像形成装置は、
液滴を吐出する１又は複数のヘッドで構成される記録ヘッドがベース部材に位置調整可能に取り付けられ、
前記記録ヘッドの位置を調整する位置調整手段と、
前記ベース部材に対して前記記録ヘッドを前記位置調整手段による調整方向と異なる方向に加圧する加圧手段と、
前記位置調整手段による調整方向に前記記録ヘッドの位置調整を行うときに、前記加圧手段による加圧力を低下させる減圧手段と、を備え、
前記位置調整手段と前記減圧手段とが連動する
構成とした。 In order to solve the above problems, an image forming apparatus according to the present invention provides:
A recording head composed of one or a plurality of heads for discharging droplets is attached to the base member so that the position thereof can be adjusted,
Position adjusting means for adjusting the position of the recording head;
A pressurizing unit that pressurizes the recording head with respect to the base member in a direction different from an adjustment direction by the position adjusting unit;
A pressure reducing means for reducing the pressure applied by the pressurizing means when the position of the recording head is adjusted in the adjustment direction by the position adjusting means ,
The position adjusting means and the pressure reducing means are configured to work together.

本発明によれば、加圧手段による加圧力を低下させて位置調整手段で記録ヘッドの位置を調整することができ、位置調整時に記録ヘッド及び位置決め部材の当接面が摩耗、座屈するおそれが低減する。 According to the onset bright, reduces the pressure applied by the pressurizing means can adjust the position of the recording head position adjusting means, the abutment surface of the recording head and the positioning member is worn, buckles for position adjustment possibility Is reduced.

Claims

A recording head composed of one or a plurality of heads for discharging droplets is attached to the base member so that the position thereof can be adjusted,
Position adjusting means for adjusting the position of the recording head;
A pressurizing unit that pressurizes the recording head with respect to the base member in a direction different from an adjustment direction by the position adjusting unit;
A pressure reducing means for reducing the pressure applied by the pressurizing means when the position of the recording head is adjusted in the adjustment direction by the position adjusting means ,
The image forming apparatus, wherein the position adjusting means and the pressure reducing means are interlocked .

The pressure-reducing means decreases the pressure of the pressurizing means of the pressurizing means in conjunction with the start of the position adjusting operation by the position adjusting means, and the pressurizing force of the pressurizing means in conjunction with the end of the position adjusting operation. The image forming apparatus according to claim 1, wherein the image forming apparatus is recovered.

3. The image forming apparatus according to claim 1, wherein the decompressing unit reduces the pressure applied by the pressurizing unit only when adjusting in one of the adjustment directions by the position adjusting unit.
