ばかれるようになっていた。Conventional technology In image printers equipped with conventional automatic paper feeding mechanisms,
As shown in FIG. 3, an automatic paper feeding mechanism is provided with a paper feeding means above the recording paper cassette 4, and at the time of paper feeding, lifts the bottom plate 11 on which a plurality of recording papers 6 are stacked and feeds the paper. had been adopted. In such an image printer, an opening 2 is provided in the device casing 1, and a recording paper cassette 4 is inserted into the device casing 1.
It is attached so that it can slide freely towards the front of the camera. A bottom plate 11 is attached to the lower part of the opening s2 so as to be rotatable about a pivot shaft (not shown) so as to lift the recording paper 8 upward. It is biased upward and lifts the recording paper 6 upward. The recording paper 6 is pressed against a recording paper stripping means 20 consisting of a belt 9 stretched between a row 27 and a roller 8 provided in the device housing 1, and a belt 9 driven via a row 28. The friction force causes the paper to be sent in the paper feeding direction. A torque limiter is built in here, and the roller 8 rotates in the same direction as the roller 8.
By means of a recording paper return means 10 located below the recording paper 6, only the topmost sheet of the recording paper 6 is conveyed to the recording section, and the rest are separated.

ことのない形状にしたものである。FIG. 1 is a schematic cross-sectional view showing the main parts of an image printer according to an embodiment of the present invention, and FIG. 2 is a perspective view of the embodiment of the present invention, showing a state in which the recording paper cassette 4 is taken out in the take-out direction BK. ing. In FIG. 1, an apparatus housing 1 includes a recording section 16 consisting of a thermal head 16°, an ink sheet 14, and a platen 13, and a recording paper guide 12, and a recording paper cassette 4 can be freely slid into an opening 2. can be attached to. The feature of this embodiment lies in the opening shape of the opening 2. The opening 2 is widened at a predetermined portion compared to the conventional case, so that when the recording paper cassette 4 is taken out, the opening 2 is opened on the upper end surface of the recording paper cassette 4 on the recording side. The shape is such that the recording paper 6 left unattended will not get scratched.

とを防ぐことができる。At the bottom of the opening 2 configured as above, there is a bottom plate 1.
1 is rotatably provided so as to lift up the recording paper 6, and is urged upward by the suppressing means 6 during paper feeding to lift the recording paper 6 upward. The recording paper 6 is pressed against a recording paper stripping means 2o consisting of a roller 7 provided in the device housing 1 and a belt 9 stretched between the rollers 8 and a belt 9 driven via the roller 8. The paper is fed in the paper feed direction by the frictional force between the paper and the paper. Here, a torque limiter is built in and low 2
By the recording paper returning means 10 which rotates in the same direction as the roller 8 and is provided below the roller 8, only the topmost sheet of the recording paper 6 is guided to the recording paper guide 12 and conveyed to the recording section 16.
The rest will be judged. At the same time as paper feeding ends, the separated recording paper 6 tries to be stored in the recording paper capacity center 4 as the bottom plate 11 and the recording paper return means 10 descend, but some of the recording paper 6 It rides on the edge of the paper cassette 4. Here, the opening 2 of the device housing 1 is opened up to the contact point of the recording paper stripping means 2o and the recording paper return means 10 in the conveyance direction to the recording section, and furthermore, in the height direction, at least the recording paper cassette 4 is opened. Recording paper stripping means 20 from the upper end surface on the recording unit side of
Since the opening extends to the lower end surface of the opening 2, the recording paper 6 will be caught in the opening 2 even if the recording paper 6 is placed on top of the upper end surface of the recording paper cassette 4 on the recording section side when replenishing or replacing the recording paper 6. The recording paper cassette 4 can be taken out without any trouble, and damage to the recording paper 6 and failure to take out the recording paper cassette 4 can be prevented.
