Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording device. In particular, the present invention relates to a usage pattern of an image recording device that is thin and compact.

[0002]

2. Description of the Related Art In recent years, host computers such as personal computers have been downsized, and recently, A4 size notebook type computers have become the mainstream. Correspondingly, a small image recording device, which is an output device, has been developed.

FIG. 5 is a sectional view showing a schematic structure of a conventional image recording apparatus.

As shown in this figure, the conventional image recording apparatus is made thin, and the image recording means 100, the recording medium conveying means 101, and the electrical equipment section 102 are arranged vertically.
The recording medium 103 is sandwiched by pinch rollers, conveyed, and recorded by a recording head.

In a conventional image recording apparatus whose size is becoming smaller, when recording on a thick recording medium such as a postcard, the paper is passed from the back surface to the front surface of the machine body in a flat state. At this time, since the thin recording apparatus main body had to be used upright, it was very unstable. As a countermeasure against this, it has been proposed to provide a fall prevention member on the recording apparatus main body, but there is a drawback in that the external dimensions of the apparatus main body become large.

On the other hand, the recording head prints in the horizontal direction when the conventional apparatus is in use. However, in the case where the ink jet method is adopted, the accuracy of the ink landing position is low in the horizontal printing operation, and the landing is performed. Ink may droop later, which is not preferable.

In consideration of the above points, there has been proposed a notebook type printer in which the main body of the apparatus is in a flat state when it is stored, and when it is used, it is folded into an L shape.

[0008]

However, although the conventional recording apparatus of the background secures the stability in the use state and the downward printing, it is difficult to handle due to the rattling of the hinge portion when it is stored or carried. There is a problem that it is difficult.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide an image recording apparatus which satisfies the demand for miniaturization and stabilizes the handling when stored or carried. There is.

[0010]

And a cover member movably attached to one surface of the cover member, the cover member being attached to the constituent member so as to have a rotation preventing means and a tray mechanism for a recording medium. It is characterized by being

The cover member is attached to one molding member so as to be rotatable around the fulcrum via a fulcrum, or is engaged with the one molding member so as to slide on the upper surface of the constituent member. It may be one that has been.

[0012]

According to the present invention configured as described above, the cover member is provided on one surface of an integral component formed by rotatably coupling one end of each of the two molding members as a common shaft, and the cover member of the rotation preventing means and the recording medium. By providing the tray so as to be movable with respect to the constituent members, the two molded members are prevented from rotating during storage and the integrated constituent member is stabilized. Further, when used, the cover member serves as a tray on which the recording medium is placed.
