In the figure, a first opening 203 is formed near the edge of the top surface of the housing cover 200 that also serves as a housing, and a second opening 204 is formed near the back (rear surface side) of the housing, while the housing is formed. Cover 20
A discharge port 205 is formed on the front surface of 0.

In the above structure, the original G is inserted with the reading surface facing down through the first opening 205, and is rotated with the contact type line image sensor 12 and the contact type line image sensor 12 in a biased state. First driven dynamically
It is held between the biasing rollers 13 and is conveyed and discharged from the discharge port 203. On the other hand, on the back side of the upper surface of the housing cover 200, a roll-shaped recording paper KR, which is a roll of heat-sensitive paper as shown in the figure, is rotatably and exchangeably held in the arrow direction, and the recording of the roll paper K2 is performed. The recording surface of the line thermal head 14 that constitutes a part of the line thermal head 14 is made to face the color developing surface, and is rolled between the second biasing rollers 15 which are rotationally driven in a biased state with respect to the line thermal head 14. The paper K2 is clamped and ejected to the outside after recording through the second opening portion 204.

Is. On the other hand, when a dedicated opening for inserting cut sheets is newly provided, for example, in the vicinity of the above-described first opening, the opening and the first opening each having at least the A4 lateral dimension in the longitudinal direction are provided. Since it is not possible to guarantee the strength of the rod-shaped partition formed between the sheet and the sheet, it is virtually impossible to set the cut sheet.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to make it possible to selectively use a cut sheet and a roll-shaped recording sheet with respect to the apparatus, and to make the apparatus compact and flat. Another object of the present invention is to provide a roll-shaped sheet holder for a facsimile machine which can prevent damage to the recording surface of the recording sheet and prevent meandering / skew.
