The journal printer is designed to pass through a writing table (not shown) and be sequentially wound on a take-up reel (not shown). In addition, in the receipt printer 2 and the journal printer, the jam sensor 1 is usually used.
The paper guide 15 is positioned by the pressing force of the detection terminal 20 of 9 to form the paper conveyance path 13 reaching the rotary cutter 12 and the writing table.

In the sheet conveying device 1 of the receipt printer 2, when the continuous paper 35 is jammed immediately before the rotary cutter 12, the continuous paper 35 curved by the jam pushes the paper guide 15 upward, When the pressing force exceeds a predetermined value, the paper guide 15 is rotated upward against the elastic force of the detection terminal 20 of the jam sensor 19. Then, the detection terminal 20 that elastically positions the paper guide 15 is not detected by the jam sensor 19.
Since a jam is detected by being press-fitted into the inside, for example, a warning is given to the user by a buzzer, and the driving of the printer unit 8, the rotary cutter 12, etc. is automatically stopped.

Here, the receipt printer 2 as described above is used.
In the paper transport apparatus 1 of, the continuous paper 3 wound in a roll shape is used.
Since the end portion of 5 has a remarkable curvature, there is a concern that this portion may enter between the paper guides 4 and 5 in a wound state to cause a jam. Therefore, in the paper transporting apparatus 1, the platen roller 11 and the like move the paper guides 4, 5 from above the hopper 22.
The curved outer surface of the continuous paper 35 that is sequentially drawn into the opening is supported by the paper support portion 23 of the paper guide 5.
By engaging the paper straightening claws 24 facing each other with the curved inner surface of the continuous paper 35, the winding of the end portion of the continuous paper 35 is straightened.

As described above, the paper support portion 23 for correcting the end portion of the continuous paper 35 and the paper correction nail 24 are arranged close to each other and face each other.
There is a concern that it will be difficult to set the continuous paper 35 in the gap between the sheet 4 and the paper support portion 23. Therefore, in this paper transporting apparatus 1, as illustrated in FIG. 9B, the paper straightening claw 24 is necessarily integrated with the printer cover 26 which is inevitably removed from the main body housing 25 of the electronic cash register 3 when the continuous paper 35 is set. By providing the sheet supporting portion 23 when setting the continuous paper 35, as illustrated in FIG.

However, when the continuous paper 35 is replaced or the jam is removed, for example, the printer cover 2 removed from the main body housing 25 by the user is actually used.
In some cases, the receipt printer 2 starts to be driven without forgetting to set 6. In such a case, the sheet conveying apparatus 1 of the receipt printer 2 conveys the continuous sheet 35 in a state where the sheet correction claw 24 is not located on the sheet supporting portion 23. Therefore, as illustrated in FIG. The curved end portion of 35 may enter the space between the paper guides 4 and 5 without being straightened to cause a jam.

The electronic cash register 3 described above is also used.
Then, in the recess of the main body housing 25, the printer cover 26
