Description

[Detailed explanation of the idea] (Technical field) The present invention relates to a roll paper holder.

(Prior Art) In conventional electronic equipment with a printer, the method shown in FIGS. 1 and 2, for example, has been used as a method of holding roll paper. FIG. 1 shows a structure in which a support shaft 3 is inserted into a hollow core 2, and this support shaft 3 is dropped into a receiving groove 4a of an electronic device main body 4. However, this method has drawbacks such as the support shaft 3 being easily lost and the loading of the roll paper being troublesome. On the other hand, FIG. 2 shows a structure in which the roll paper 1 is rotatably held on a support arm 6 fixed to an electronic device main body 5 by its support shaft 7. In FIG. However, since the roll paper is exposed in this way, the roll paper is easily soiled.

(Objective) The present invention was made in view of the above-mentioned drawbacks, and an object of the present invention is to provide an electronic device with a printer that has a simple structure, allows easy attachment and detachment of roll paper, and does not stain the roll paper.

The structure of the present invention that achieves the above object is as follows: a holder body that stores the roll paper; a lid body that can be opened and closed with respect to the holder body; a pair of projections that removably support the lid, when the lid is closed, the lid restricts an increase in the distance between the pair of projections, and when the lid is opened, the restriction is regulated. A roll paper holder characterized in that it is configured to be released.

(Embodiment) FIG. 3 shows an embodiment of the present invention, in which reference numeral 9 denotes an electronic device with a printer, for example, an electronic calculator body with a printer. 10 is a display section, 11 is a keyboard section, 12 is a printer knob, 13 is a roll paper holder, and 14 is a roll paper.

Details of the roll paper holder 23 are shown in FIGS. 4A, B, and C. Here, the upper cover 25, which is the lid of the roll paper holder, is rotatably attached to the lower cover 26, which is the main body of the roll paper holder, through a protrusion 27, and the lower cover 26 is attached to the computer main body 9. It is attached by inserting the hook-like attachment part 28. A pair of projections 29 that fit into the hollow core are integrally formed on both side walls of the lower cover 25 at positions facing the hollow core of the roll paper 1. This protrusion 29 has a function of supporting the roll paper 1 at both ends, and its end face is tapered and inclined, so that the roll paper 1 can be easily attached by press-fitting it.

Next, see Chapter 5 on how to use the roll paper holder.
This will be explained using Figures A to F.

First, the roll paper holder 23 is attached to the main body 9 [FIG. 5A]. Next, open the upper cover 15 [Fig. 5B]. Then, put the roll paper 1 on the lower cover 26.
Pay attention to the way the paper comes out from above and insert the protrusion 29 into the protrusion 29.
Press in while sliding down the slope of No. 9 [Fig. 5C].
Then insert the tip of the roll paper 1 into the paper insertion slot 2 of the main body 9.
0 and feed it to the specified position using the printer knob 12 [Fig. 5D]. Finally, close the upper cover 15 again to complete the setting of the roll paper 1 (Fig. 5E). At this time, since the outside of both protrusions 19 is pressed by the side surface of the upper cover 25, the roll paper 1
It will not come off due to friction etc. When the printer is used in this state and the roll paper 1 is used up, open the upper cover 25 and pull out the core rod 1a of the roll paper 1 upward while pressing the protrusion 29 outward (FIG. 5F).

In this way, in this embodiment, the protrusion 29 is connected to the lower cover 1.
Since it is provided integrally with 5, there is no need to worry about losing it, and the structure is further simplified. Further, since the roll paper 1 is usually covered with upper and lower covers 25 and 26, it will not get dirty or fall.

Further, in the above embodiment, even when the roll paper is used up, the protrusion 29 can be moved by opening the upper cover 25, and the core rod 1a of the roll paper 1 can be easily removed. Then, when another roll paper is supported by the protrusion 29 as described above and the upper cover 25 is closed again, the movement of the protrusion is regulated by the upper cover 25 and the roll paper is reliably supported. In this manner, in the above embodiment, the roll paper can be easily replaced.

(Effects) As described above, according to the present invention, it is possible to provide an electronic device with a printer that has a simple structure, allows easy installation of roll paper, and is less likely to stain the roll paper.

Further, in the present invention, even when the roll paper is used up, the protrusion can be moved by opening the lid, and the roll paper can be easily removed. Then, when another roll paper is supported by the protrusion and the lid is closed again, the movement of the protrusion is regulated by the lid and the roll paper is reliably supported. In this way, in the present invention, the roll paper can be easily replaced.
