At this time, the insertion direction of the document holder 11 with respect to the recording device 20 can be easily visually recognized by the identification mark 19 provided on the holder cover 13 of the document holder 11, so that the insertion direction of the document holder 11 is wrong and, as a result, It is possible to prevent an image in which the vertical direction is reversed from being recorded on the paper 43 during recording.

Further, since the periphery of the document 14 placed on the document holder 11 of the present embodiment is covered with the white mask portion 17, for example, a thick document 14 such as a photograph is printed. So that the mounting surface 12a of the holder base 12
Even when the step 9 is formed on the edge of the document 14 placed on the sheet, the step 9 can be reliably covered with the white mask portion 17.

That is, as shown in FIG. 14, since the step portion 9 can be covered with the white mask portion 17, the light emitted from the light source 38 of the image scanner 28 toward the original 14 is a white mask. The image is reflected by the section 17, and the original 14 is read by the image scanner 28.
In the image reading state in which the image information of
The generation of the conventional shadow 10 due to the step 9 is reliably prevented and is not read as image data (it is a non-recording portion when recording is performed on the paper 43). It can read accurate image data.

Further, according to this embodiment, unlike the conventional case,
Since the image data has no extra data due to the shadow 10, it is not necessary to provide a conventional display device for displaying the read image information for trimming, an input device for processing the read image information, a processing program, and the like. In addition, it is possible to surely eliminate the disadvantages that the recording device 20 is upsized, the number of parts is increased, the economical burden is increased, and a great amount of labor is required for trimming.

The image data read by the image scanner 28 is used as recording data for recording, and at the time of recording, a paper 43 selected from a postcard, a Christmas card, plain paper, stencil paper, etc. is recorded in the recording device 20. The thermal head 32 is set by driving the recording device 20 based on the control command sent from the control means 27 after setting.
By this, the ink of the ink ribbon is transferred to a desired position on the paper 43, and a desired image is recorded on the paper 43.

When the image data read by the image scanner 28 is recorded on a paper 43 such as a postcard, a Christmas card or plain paper, an ink jet head (not shown) may be used instead of the thermal head 32. Good.

15 and 16 show a second embodiment of the document holder according to the present invention. In the document holder 11A of this embodiment, the mask portion 17 described above is provided on the holder cover 13A. Instead, it has a frame-shaped white mask member 17A formed separately. The other structure is similar to that of the document holder 11 of the first embodiment described above.

That is, the document holder 11A of this embodiment
Is a holder base 12 having a placement surface 12a on which a document 14 is placed, and an entire light transmission part 1 made of a light transmission material.

A mask member 17A having a rectangular frame shape is detachably interposed between the surface of the document 14 and the holder cover 13A so as to partially cover the periphery of the document 14 when the document 14 is placed. ing.

With such a structure, the mask member 17A of the original holder 11A of this embodiment has the same effect as the mask portion 17 of the first embodiment described above, and if necessary, has a frame shape. Since the internal shape of the mask member 17A can be arbitrarily selected from various shapes such as a heart shape and a diamond shape, for example, as a manuscript 14 for creating a New Year's card, a photograph It is possible to solve the inconvenience that the photograph must be cut when the original 14 is a heart-shaped copy.

That is, the present embodiment has the effect that the image scanner 28 can read a part of the original 14 in an arbitrary shape.

The present invention is not limited to the above-mentioned embodiments, but can be modified as required.
