Description

Description: TECHNICAL FIELD The present invention relates to an output device such as an electronic computer or a word processor, and a printer capable of printing a single-cut sheet and continuous paper at the same time.

[Conventional technology]

Conventionally, a printer that handles single-cut sheets and continuous paper and supplies the single-cut sheets horizontally from the front has excellent operability of single-cut sheets. That is, as shown in FIG. 5, the single-cut sheet can be fed horizontally straight from the front side, so that the single-cut sheet 1 can be printed without being bent, and at the same time, the conveyance roller 5 is arranged before and after the print head 3 and the platen 4. However, it is also possible to print a slip having a short length by transporting the single slip 1 while sandwiching it completely.

However, as shown in FIG. 6, when the continuous paper 2 is pulled and printed by the pull tractor 6 with the transport roller 5, it is difficult to synchronize the transport speeds of the transport roller 5 and the pull tractor 6. A mechanism for pulling the upper roller of the transport roller 5 upward to make a gap is required, and when printing the single-cut sheet 1, it is necessary to remove the continuous paper one by one, which is complicated in operation.

The one in which such a problem is improved is disclosed in JP-A-56-159186.
As shown in FIG. 7, the pull tractor 6 is arranged in the lower rear part of the platen 4 as shown in FIG. 7, the continuous paper 2 is supplied from the lower rear part of the printer 1, and the platen 4 is not passed through the feeding roller 5. The invention was made by turning it back from below and pulling it to the lower rear.

According to this known invention, when printing the continuous paper 2,
There is no need to raise the transport roller 5, and even when printing a single-cut sheet 1, there is no need to remove the continuous paper 2,
In addition, continuous form 2 and cut sheet 1 are printed at the same time, and continuous form 2
It is also possible to leave the printing of as a record.

[Problems to be Solved by the Invention]

In this known invention, there is a problem in the operability at the time of setting the continuous paper because the continuous paper has to be set from the lower rear part and the way of passing the continuous paper around the platen is not easy.

In addition, JP-A-60-131272 discloses that a single-cut sheet and continuous paper can be printed at the same time, a table on which the single-cut sheet is placed in front of the printing unit, and a continuous table provided under the table. A printer provided with a conveying unit that conveys a sheet to a printing unit and moves a continuous sheet that has passed through the printing unit is described. However, in this example, continuous paper is inserted from the front of the printer and ejected to the front, so-called full-face insertion / front ejection method. There is a problem that the operability of continuous forms is poor.

Further, Japanese Patent Laid-Open No. 56-42673 describes that a printer is configured to convey continuous paper from the front side to the rear side of a printing unit. However, in this example, it is impossible to print a single sheet with continuous paper set.

In addition, Japanese Utility Model Laid-Open No. 144-144305 or Japanese Patent Laid-Open No. 57-
In the 107873 publication, in a printer, a guide plate (guide member) for diverting the paper conveyed to the printing unit to contact the printing unit of the platen and wrap it around, and a guide plate drive for removing the guide plate from the printing unit It is described that the means and are provided. However, in these examples, the recording paper is wound around the printing portion in a U-shape in both the single-cut form and the continuous form.
When the recording paper is attached, the guide plate (guide member) for half the circumference of the platen is moved to the end of the ticket turning, so that the recording paper can be easily set on the printing section. In both cases of continuous paper and continuous paper, such a guide plate (guide member) is required. It does not affect the insertion direction of the single form when inserting the single form, and does not turn the continuous form downward when loading the continuous form.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a printer which eliminates the problem of operability when setting continuous paper.

[Means for solving the problem]

In order to achieve the above object, the present invention is capable of printing a single-cut sheet and a continuous sheet at the same time, and a table for supplying the single-cut sheet to the front side of a printing unit including a print head and a platen, and a table provided below the table. And a transport device for transporting the continuous paper to the printing unit, and a drive unit provided on the rear side of the printing unit to drive the continuous paper, and inserts both the cut sheet and the continuous paper from the front. In the printer of the method of discharging to the rear, provided in the rear part of the printing unit, when the continuous paper is mounted, the continuous paper conveyed to the printing unit is turned downward and guided to the driving means, It is characterized in that it is provided with a guide plate that retreats during printing of continuous paper and the cut sheet, and a drive device for the guide plate.

[Action]

From the front side of the printer, continuous paper is fed from the bottom of the table that supplies cut sheets, is provided on the front side of the printing section, and is conveyed to the upper side of the platen by a conveying device that conveys the continuous sheet to the printing section, and is further guided. The continuous sheet is turned downward by the guide plate driven to the upper side of the platen by the plate driving device, is contacted with the printing portion of the platen and is wound around, and is guided to the driving means located at the rear side to the driving means. It is set manually. Then, for printing, the guide plate is removed from the upper side of the platen by the guide plate driving device.
