Abstract

PURPOSE:To operate a device with a single hand and continuously obtain a long-sized copy by transmitting the driving force from a scanning rotating body to a recording paper feeding-out means to feed out a recording paper in accordance with the extent of rotation of the scanning rotating body. CONSTITUTION:A scanning roll 7 is rotated on an original 1 to be copied, and 1 feeding-out roll 8 is connected to the roll 7 by a belt 15 so that the roll 8 is rotated in accordance with the extent of rotation of the roll 7. A thermosensitive roll paper 9 and the feeding-out roll 8 are pressed to each other on the contacting surface with a strong frictional force by a pressing means omitted in the figure. If a picture of high density is required, the surface of the original 1 is slowly scanned to not only increase the exposure of the original but also extend the time when the recording paper stays in the position of a thermal head 10, and the picture of high density is obtained. If a picture of low density is required, the scanning speed is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a small-sized scanning image forming apparatus that forms an image by moving an image reading section eight times over the surface of a document.

[Conventional technology and problems] Conventionally, this type of device feeds the recording paper by holding one end of the recording paper with your hand and moving the main body, but it is difficult to operate it with one hand or when making long copies. There were drawbacks such as the inability to perform continuous copying operations when copying.

[Configuration for Solving Problems] The present invention has been made to solve the problems of the prior art, and has the following features. That is, a scanning rotating body that contacts the document surface and rotates with the operation of the image reading section, a recording paper feeding means that feeds out the recording paper, and a drive that transmits the driving force from the scanning rotating body to the recording paper feeding means. There is a scanning type image forming apparatus 7 which is characterized in that it has a force transmitting means and feeds the recording paper according to the amount of rotation of the scanning rotor.

[Embodiment] FIG. 1 is a sectional view showing one embodiment of the present invention. Manuscript 1
The scanning image forming apparatus A placed above will be described below. The light emitted from the LED lamps 3a and 3b for illuminating the original through the plate-proof glass 2 is reflected on the surface of the original, passes through the mirror 4, the imaging lens 5, and forms an image on the CCD sensor 6. There is. The information photoelectrically converted by the COD sensor 6 is sent to the thermal head 1 via the control unit 13.
0 and recorded on heat-sensitive roll paper (recording fa) 9. 14 is a power source.

On the document surface, a pair of scanning rollers 7 and rollers 12 keep the distance between the document surface and the cold protection glass 2 constant.

The scanning roller 7 rotates over the original to be copied, and is connected by a belt 15 so that the feed roller 8 rotates in accordance with the amount of rotation.

The heat-sensitive roll paper 9 and the feed roller 8 have a large frictional force on their contact surfaces and are pressed against each other by a suppressing means (not shown).

As a result, when a high-density image is required, by scanning the document 1 slowly, the exposure amount of the document increases and the retention time of the recording paper in the thermal head 1o becomes longer, resulting in a high-density image. It becomes possible to obtain. On the other hand, if you need an image with low density, you can increase the scanning speed.

Further, the scanning roller in the wooden embodiment may be one in which a belt is passed between two rollers, and the driving force transmission means by the belt 15 may be a gear train or a chain.

[Effects of the Invention] According to the present invention, since the recording paper is automatically fed out as the image forming apparatus scans, there is no need to hold down the QH75 portion of the recording paper by hand, and operation can be performed with one hand. You can also make continuous copies of shaku.
