Abstract

PURPOSE:To prevent the increase of the number of parts including a protective lid even when an opening for inserting a printing sheet is installed at the position corresponding to downsizing. CONSTITUTION:A cord storage chamber 2 is installed surrounding an opening 5 for inserting a printing sheet formed on the back of a main body case 1. A door 3, which closes the chamber 2 during downtime, is turned on a shaft 10 when printing is carried out, so that a printing sheet 4 fed externally can be led to the opening 5 smoothly along the surface of the door 3 to be sent to a printing part by passing between paper feed rollers 7 and 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device, and more particularly to an electronic device having a case with a printing paper insertion port.

[0002]

2. Description of the Related Art In recent years, as can be seen in word processors, as electronic devices have become smaller, printers have also become smaller and the shaft diameter of rollers for feeding printing paper has become smaller, but paper can be fed smoothly. Therefore, it is necessary to prevent the radius of curvature of the introduced printing paper from becoming small.

Conventionally, as shown in FIG. 4, an electronic apparatus of this type has an example in which a printing paper 4 which advances along a paper supporter 19 is introduced into a printing paper insertion port 15 provided on a side surface of a main body case 11, Paper feed roller 1 of printer 16
It is sandwiched between 7 and 18 and sent to a printing section (not shown) in the upper part of the figure to be printed and then discharged to the outside. At the end of printing, the paper supporter 19 moves to a position where the printing paper insertion port 15 is closed. The cord storage chamber 12 has a lid 23 that opens and closes and serves to protect a power cord (not shown).

[0004]

In the above-mentioned conventional electronic device, the printing paper insertion port 15 is on the side surface, and when downsized, the shaft diameter of the paper feed rollers 17 and 18 becomes small and the paper cannot be fed smoothly. There is a drawback that.

Further, as shown in FIGS.
When the printing paper insertion opening 25 is provided on the back surface of the main body case 21 so that the radius of curvature of the printing paper sent through the sheets 7 and 28 does not become small, a dedicated lid 33 must be provided for protection when not printing. Therefore, there is a drawback that the number of parts increases.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic device which can smoothly advance a printing sheet even if it is miniaturized, and which does not cause an increase in the number of parts due to a dedicated protective lid, a paper supporter or the like.

[0007]

In the electronic apparatus of the present invention, a case is provided with a chamber surrounding the printing sheet insertion port from the outside, and the chamber allows the printing sheet to pass through a wall facing the printing sheet insertion port. For opening and closing means.

The opening / closing means may be plate-shaped and held at a position where the printing paper passing along the surface of the opening / closing means is smoothly introduced into the printing paper insertion port during printing.

[0009]

Since the chamber provided in the case surrounds the printing paper insertion port from the outside, a dedicated lid or the like for protecting the insertion port is not required and the number of parts is not increased.

If the opening / closing means is plate-shaped and is held at a position where the printing paper is smoothly introduced into the insertion port during printing, a separate dedicated paper supporter is not required.

[0011]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a perspective view of a first embodiment of an electronic device according to the present invention, FIG. 2A is a cross-sectional view of the electronic device of FIG. 1 without printing, and FIG. 1B is an electronic device of FIG. It is a cross-sectional view at the time of printing of the device.

In this electronic device, a printing paper insertion port 5 is provided on the back side of the main body case 1, and a code storage chamber 2 is provided surrounding the printing paper insertion port 5. In the code storage chamber 2, a door 3 for passing the printing paper 4 is attached to a wall 9 facing the printing paper insertion port 5. The door 3 is also used to store a power cord (not shown) in the cord storage chamber 2, rotates about the shaft 10, and closes the cord storage chamber 2 as shown in FIG. 2 when not printing. To protect the inside and the printing paper insertion slot 5 and print.
The printing paper 4 which is rotated and held at the position shown in FIG. 1 and advances along the surface is smoothly introduced into the printing paper insertion opening 5. Printing paper 4
Is inserted from the printing paper insertion port 5, sandwiched between the paper feed rollers 7 and 8 of the printer 6, printed by a printer (not shown), and discharged to the outside.

In this electronic device, since the printing paper insertion port 5 is provided on the back side, the radius of curvature of the printing paper 4 introduced into the printing section via the paper feed rollers 7 and 8 becomes relatively large. , The paper can be fed smoothly even if it is downsized, and the printing paper insertion slot 5 is surrounded by the code storage chamber 2.
A dedicated lid or the like for protecting the printing paper insertion port 5 is not required. Further, at the time of printing, the printing paper 4 which the door 3 advances along the surface is smoothly introduced into the printing paper insertion port 5, so that a dedicated paper supporter is not required.

In the present embodiment, the chamber surrounding the printing paper insertion port 5 is a cord storage chamber for storing the power cord, but it goes without saying that it may be used for other purposes.

FIG. 3 (a) is a cross-sectional view of the second embodiment of the electronic apparatus of the present invention when no printing is performed, and FIG. 3 (b) is the same figure (a).
FIG. 7 is a transverse cross-sectional view of the example of FIG.

This electronic device has a lid 1 instead of the door 3 shown in FIG.
3 is provided. When the lid 13 is not printed, it is shown in FIG.
As shown in FIG. 3A, the code storage chamber 2 is held so as to be closed, and when printing, as shown in FIG. 3B, the code storage chamber 2 is inserted and held in a gap 11 in the inner portion of the code storage chamber 2. It

The electronic device of this embodiment can also be made compact as in the case of FIGS. 1 and 2, and does not require a dedicated lid or the like for protecting the printing paper insertion port when printing is not performed.
Further, there is no need for a dedicated paper supporter for introducing the paper into the insertion slot during printing.

[0019]

As described above, according to the present invention, since the chamber surrounding the printing paper insertion opening is provided in the case, even if the printing paper insertion opening is provided on the back surface for downsizing, the insertion opening is protected. Does not require a dedicated lid or the like, the chamber can be used for the purpose of a cord storage chamber, etc., and the opening / closing means provided in the chamber has a plate shape and advances along the surface of the opening / closing means during printing. The printing paper that is held at the position where it can be smoothly introduced into the printing paper insertion port does not require a dedicated paper supporter separately, and therefore has the effect of suppressing an increase in the number of parts.
