Abstract

PURPOSE:To enable to easily insert a recording medium without considerably increasing the area occupied by a printer, by providing a detachable medium-inserting part on the lower side of a main body of the printer. CONSTITUTION:First, when manually inserting the recording medium such as a slip, the medium is fed in between guides 31, 32 in the medium-inserting part 30, and is fed through a medium feeding-out port 33 and a medium-inserting port 24 provided at a lower part of the main body of the printer to a position between a platen 17 and pinch rollers 18. When automatically supplying a cut sheet, cut sheets 42 are contained in a cut-sheet stacker 35, and are normally pressed against a picking roller 36 by a medium pusher 41. When the roller 36 is driven by a picking motor 39, the cut sheets are supplied through the port 33 by one sheet at a time. In this case, since the recording medium can be inserted from a lower position on the front side of the printer, the inserting operation is facilitated. In addition, the width of the printer is the same as that of a conventional corresponding printer, and the increase in the area occupied by the printer is slight.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a printer device used as an output device of an electronic computing device or the like.

PRIOR ART AND PROBLEMS The mainstream of conventional printer devices has been to use continuous forms with Nuproket holes on both sides of the printing paper. When using a cut sheet in such a printer device, as shown in FIG. The paper is passed between the printer and the print head 4, printed, and then discharged in the direction of arrow Q. However, such a printer device has a drawback that when placed on a desk, the insertion position of the medium is high or is far away from the operator, making operation difficult. Furthermore, there are some printers in which the printer itself is placed on its side and the medium is inserted horizontally forward, but this has the disadvantage that the printer occupies a large area and the printed state cannot be seen.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a printer device that is easy to operate when using a cut sheet and does not require a large area.

According to the present invention, there is provided a printer main body into which a medium is inserted upward from a lower medium insertion port and prints on the medium, and a removable medium inserter located below the printer main body. To provide a printer device characterized in that a mechanism and an insertion part having a feeding mechanism that contacts a medium inserted into the medium insertion part and feeds out the medium in the direction of the medium insertion opening are separable. achieved by.

Examples of the invention Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a diagram for explaining the printer device according to the present invention. In the figure, 10 is the printer main body, 11 is the print head, 12 is the carrier, 13° 14 is the guide shaft, 15 is the space belt, 16 is the space motor, 1

0 indicates a drive gear, 41 indicates a medium pusher, and 42 indicates a cut sheet tractor.

As shown in FIG. 2, this embodiment is composed of a medium insertion section 30 and a printer main body 10 mounted thereon. It has a structure that allows it to be attached and detached. The printer main body IO has a single or multi-nozzle printing pad 1 that can selectively eject ink particles and perform dot printing using a control device (not shown).
1, the print head is mounted, and the guide shaft 13° 14 is moved through the entire spacer 7 belt 15 by the spacer motor 16.
a carrier 12 that is reciprocated along
7, a sprocket 20 for paper feeding, etc., and a manual medium insertion port 23 is provided on the top surface of the casing, and a lower medium insertion port 24 is provided on the bottom surface. Further, a medium guide 25 is provided upward from the lower medium insertion port 24, and a medium set sensor 26 is provided at the end thereof. On the other hand, the medium insertion section 30 has a medium outlet 33 opened on its upper surface at a position corresponding to the lower medium insertion opening 24 of the printer main body, and a medium guide 31, 32 for feeding the cut sheet into the medium outlet.
A cut sheet stacker 35 is provided inside the casing, which is equipped with a bin roller 36 driven by a medium pusher 411 and a big motor 39, and can feed cut sheets one by one to the medium outlet 33.

The medium guide 31 can be opened and closed by a bin 43, and when storing cut sheets 42 in the cut sheet stacker 35, it can be opened to the position shown by the two-dot chain line.

The operation of this embodiment constructed in this way will be explained with reference to FIG. 2.

First, in the case of manual insertion of a medium such as a cut sheet, the medium insertion section 30
A medium is fed between the medium guides 31 and 32 of the medium. In this case, the medium is bent upward at the tip of the medium guide 31 and enters the lower medium insertion port 24 of the printer body through the medium delivery port 33, and is further guided by the medium guide 25 and reaches the medium set sensor 26. When the media set sensor fully detects that the leading edge of the media has passed, the paper feed motor 21 rotates, sucks the media between the platen 17 and the pinch roller 8, and discharges it in the direction of arrow P above the printer body. . During this time, predetermined data is printed by the print head 11.

Next, in the case of automatic supply of cut sheets, the cut sheets 42 are stored in the cut sheet stacker 35. The cut sheet is constantly moved to the pink roller 3 by the medium pressure 41.
6, and when the big roller 36 is driven by the big motor 39, the one sheet in contact with the roller is sent out toward the medium delivery port 33, and from then on, the same process as in the case of manual insertion described above is carried out. Printing is performed.

In this embodiment configured in this way, the medium can be inserted from a low position at the front of the device, making it very easy to operate, and the width of the device remains the same as before, so there is only a slight increase in the occupied area. be.

It should be noted that this embodiment can be used as a stand-alone printer body, and when the medium is a continuous form 19, feeding and ejection are performed from the rear of the apparatus as in the conventional case.

In the case of a single sheet, it can be inserted through the manual insertion slot 23 and printed.

Effects of the Invention As described in detail above, the printer device of the present invention has the following advantages:
By providing a removable media insertion section below the printer main body, the area occupied by the device is not increased significantly.
This has the great effect of making the media insertion operation extremely easy.
