Abstract

PURPOSE:To enable the setting and taking out of paper to be carried out in front of a printer, by a method wherein a delivery opening for a cutform and a stacker are provided to an upper cover supported in a rotary free manner, a continuous paper delivery opening to the rear of a body cover, and a paper feed opening is provided to a front of the body cover. CONSTITUTION:When a cutform 16 is inserted from a feed opening 12a, printed paper is stacked with a cover bottom plate 10 and a stacker 8. When continous paper 17 is inserted from a feed opening 12c, it passes a printing part and is discharged outside through a rear delivery opening 12d with a rear tractor 18. When paper 17 is setted to the tractor 18, the setting is carried out by opening an upper cover 4 rearward. For a short cutform, since the upper cover 4 is made of a recessed form, the paper always goes out from the upper cover and can be taken out without opening the upper cover. Further, by bringing the stacker 8 down this side as shown by a chainline, the continuous paper 17 can be seen and the paper can be cut off from the front.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a printer, and in particular to a stacker set with an upper cover and a continuous paper ejection port suitable for a printer capable of printing both single sheets and continuous paper. The present invention relates to a cover structure that rotatably supports a provided main body cover.

[Conventional technology]

For printers that can print both single sheets and continuous paper,
It is well known that when using single sheets, a stacker, etc., which is a separate part, is attached and used, and when using continuous paper, the cover of that section is removed or partially opened when setting the paper, but this method is well known. In this case, the paper must be set at the rear of the device, which is inconvenient for operation and requires dead space for this operation.

Note that Japanese Patent Laid-Open No. 61-235172 discloses a device in which all the sheets are fed from the rear side of the cover and discharged to the front side.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology lacks consideration for paper setting properties and paper cutting properties, and there is a problem in that the entire apparatus cannot be operated only from the front side.

An object of the present invention is to provide a printer in which all operations such as setting and taking out paper can be performed from the front of the device.

[Means for solving problems]

The above purpose is to support the upper cover so that it can rotate freely on a bearing provided at the rear of the main body cover, to provide the upper cover with a cut sheet discharge port and a stacker, to provide a continuous paper discharge port in the lower rear part of the main body cover, and to This is achieved by providing feed ports for single sheets and continuous paper at the front of the cover.

[Function] The main body cover is a cover that is fixed to the bottom frame with screws, etc. For long paper such as continuous paper, the fixed side cover has an ejection port, and the rotating or removable cover does not have an ejection port. Focusing on the fact that short sheets of paper such as single sheets can be placed in a rotating or removable cover without any operational problems, we created a recess in the top cover that doubles as part of the stacker and allows the stacker to rotate freely in the top cover. This engagement prevents the stacker from hitting and damaging the lower desk etc. when the upper cover is opened. In the above configuration, by providing the rotation support part of the upper cover at the rear of the main body cover, the inside of the apparatus can be seen simply by opening the upper cover, continuous paper can also be set from the front of the apparatus, and the paper path Trouble can also be dealt with from the front. Also, since part of the stacker is rotatably engaged with the cover,
By tilting this stacker toward you, you can cut out the continuous paper at the bottom.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The printer main body 1 is fixedly assembled on a bottom frame 2, and is covered with a main body cover 3 and an upper cover 4. That is, the printer main body 1 is housed in a box formed by the bottom frame 2, the main body cover 3, and the upper cover 4. The body cover 3, which is in the form of a housed body, is fixed to the bottom frame 2 with screws (not shown). The upper cover 4 is rotatably supported by bearings 5 provided on both sides of the rear part of the main body cover 3 (on the right side as viewed in the drawing).
When opened, the position is maintained by a stopper 6 fixed to the main body cover 3.

Further, a cut sheet supply port 12a and a continuous paper discharge port 12d are provided at the front and rear portions of the main body cover 3, a continuous paper supply port 12c is provided at the front portion of the bottom frame 2, and a single sheet discharge port is provided at the rear portion of the upper cover 4. An outlet 12b is provided.

The stacker 8 is rotatably supported on a shaft by bearings 9 provided on both rear sides of the upper cover 4 by utilizing the elasticity of the stacker, and has a removable structure.

The rear central part of the upper cover 4 is formed in a concave shape to facilitate the removal of short sheets, and the bottom plate 10 also serves as a part of the stacker, and a sheet discharge port 1 is provided below the rear wall 11.
2b is provided, and the printer body 1 is installed inside it.
A guide 13 is fixed for communicating between the upper cover 4 and the upper cover 4. The stacker 8 is located on an extension of the cut sheet discharge port 12 and the sheet discharge path of the bottom plate 10.

The printer with the above configuration has a dedicated printer stand 14.
Alternatively, it is installed and used on a transport desk 15 or the like.

In such a configuration, when printing a single sheet, the sheet 16 is set on the front terrace 7 of the main body cover 3 and inserted through the supply port 12a as shown in FIG. 10 and stacker 8.

On the other hand, in the case of continuous paper 17, it is inserted through the supply port 12c provided in the bottom frame 2 at the lower front, as shown in FIG. When setting the paper 17 on the tractor 18, the upper cover 4 is opened rearward as shown in the figure.

According to this embodiment, since the upper cover is made concave even for short sheets, the paper always comes out from the upper cover and can be taken out without opening the upper cover. Also,
By opening the upper cover 4 backward, you can see the inside of the printer from the front, so you can easily set continuous paper on the tractor 18, and by feeding the paper by hand, you can ensure that the paper is securely placed inside the main body cover 3. It can be made to pass through the discharge port 12d. Since the stacker 8 rotates, it can escape onto the desk 15 at the rear as shown by chain lines in FIG. 2, and the upper cover 4 can be reliably opened without removing the stacker 8.

Furthermore, by tilting the stacker 8 forward as shown by the chain line in FIG. 1, the continuous paper 17 can be seen and the paper can be cut from the front. Furthermore, there is no need to remove the stacker 8 by simply folding it forward during transportation. Also, stacker 8
Although the rear end is raised, it may be reversely lowered.

〔Effect of the invention〕

According to the present invention, cut sheets and continuous paper can be set and taken out from the front of the printer.
