Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the printer 1 of the embodiment with the opening / closing exterior cover partially opened, FIG. 2 is a perspective view showing the printer 1 of the embodiment with the opening / closing exterior cover fully opened, and FIG. FIG. 3 is a perspective view showing a state in which an open / close exterior cover of the printer 1 of the embodiment is closed.

As shown in FIGS. 1 to 3, a printer 1 according to an embodiment has a first outer cover 2 and a second outer cover 3 which are opened when a paper jam or maintenance occurs due to a trouble.
Are integrated on the front side of the entire apparatus. The first and second exterior covers 2 and 3 are opened at different places between two-sided printing and one-sided printing. That is, the first outer cover 2 is used for troubles such as paper jam during duplex printing.
The first and second exterior covers 2 and 3 are opened and closed together in case of trouble during single-sided printing. Since simplex printing is frequently used, the first and second covers 2 for simplex printing,
Opening of the 3 is easy to understand second provided on the front side of the device body
Is used. First operation button 1 used for first exterior cover 2 that opens and closes during double-sided printing
1 was provided on the side of the apparatus main body. As a result, a malfunction can be prevented, and the operation can be easily understood and the operability is improved.

Further, a control panel 21 is provided. LED linked to this control panel 21
Thus, the first operation button on the side of the apparatus and the second operation button on the front of the apparatus are separately specified. This makes it easier for the user to understand.

FIG. 4 is a side view of the stopper according to the embodiment.
The top cover 4 is provided with a stopper 5 that can be turned upside down to stop the conveyance of the printed paper 6. Conventionally,
When the long paper 7 is sent out, the stopper 5 is turned down so as not to hinder the discharge of the paper. In the present invention, the standing shape, position, and height of the stopper are set so as to correspond to all sizes of paper. Such a paper fall prevention stopper is provided on the top cover. The paper fall prevention stopper 5 attached to the main body of the top cover 4
Conventionally, an operation for raising and lowering each time was required according to the size of the slab. In the present invention, the stopper 5 is formed so as to correspond to all the sheets while being raised.

The present invention is an apparatus in which the front surface of the apparatus main body 1 has a structure that can be integrally opened and closed, and trouble processing can be performed only on the front part. In the conventional case, most of the troubles are handled not on the front side but on the side or rear side. The present invention is characterized in that processing can be performed on the front portion of the apparatus main body, and has a structure in which the position of a trouble can be identified by an LED linked to a control panel (control panel). The operation button is the first operation button, the second operation button
Operation buttons. Because it is linked with the LED, it is excellent in trouble handling. Also, by opening and closing only the front part during maintenance, workability is excellent.

FIG. 4 is a side view of the upper cover 4 of the sheet feeding device according to the present invention. The top cover 4 forms a discharge path from which printed paper is discharged. This top cover 4
Is provided with a paper discharge stopper 5 for stopping the paper by contacting the leading edge of the paper. Conventionally, the paper discharge stopper 5 can be turned upside down, and when printing on the long paper 7, it has to be depressed so as not to hinder the advance of the paper.
In the present invention, the paper discharge stopper 5 is set at the same angle as the upper cover body, and the paper is configured to pass over the paper discharge stopper 5 from the upper cover body. The position of the paper discharge stopper 5 is set at a position before the leading end of the paper hangs. That is, the plain paper through which the paper passes depending on the height and the angle stops before the paper discharge stopper 5. The long paper passes over the discharge stopper 5. Therefore, it is no longer necessary to raise and lower the discharge stopper.

[0013]

According to the present invention, when it is necessary to open and close the cover of the paper feeder, the open / close location is easy to understand and the operability is excellent. Accordingly, there is an effect that trouble handling and maintenance are easy and the user can easily perform the process.
