問題点を有していた。However, in the above configuration, since the recording paper is stacked on the recording paper cassette and mounted on the apparatus housing, a highly accurate guide member for mounting and fitting and a predetermined guide member are required. In the case where a mounting mechanism (not shown) for mounting at the position is necessary or the mounting is insufficient, the recording paper cassette detection switch (to prevent the lifting unit 13 or its interlocking mechanism parts from being damaged). (Not shown) or a cassette lock mechanism (not shown) during operation is necessary to prevent the recording paper cassette from being pulled out during the recording operation. However, there is a problem that the cost is increased. Also, the distance between the paper feed cassette and the paper transport
This requires two paper detectors 17 and 19, and also has a problem that the number of parts is large, the configuration is complicated, and the cost is increased.

Since the paper feed cover is provided, it is easy to check the presence or absence of recording paper, and it is sufficient that the number of paper detection units is one between the paper feed tray and the paper transport means. What is necessary is just to open the paper feed cover with a finger and put the recording paper in it, and the handle is unnecessary and the opening becomes large, so that the operability is good and the cost can be reduced. In addition, since the paper feed tray and the paper feed lid are provided with a position regulating unit that positions the recording paper at a predetermined position in the transport direction, the paper feed tray and the pickup roller due to the incomplete loading of the recording paper and the curl of the recording paper may be used. It is possible to prevent a paper feeding failure such as a paper feeding slip caused by jumping out of a predetermined position at the time of reverse rotation by touch.

有無が確認できる。If the recording paper 12 is not present, the paper detecting unit 17 does not perform the detection, so that the operation is stopped after waiting for a predetermined time, and the display means (not shown) of the present image printer displays the absence of paper. On the other hand, after the end of the recording paper 12 is detected by the paper detection unit 17, the transport path is changed to the paper discharge unit by the switching guide 6 descending. Then, the paper is discharged and stacked on the paper discharge tray 9 by the driving of the paper discharge pinch roller 21, and the operation is completed. Even if the recording paper 12 after recording is discharged to the paper discharge tray 9, the presence or absence of the recording paper 12 can be confirmed by the cutout of the front paper supply lid 22.
