Description

DETAILED DESCRIPTION OF THE INVENTION Second Object of the Invention (Field of Industrial Application) The present invention relates to the structure of a paper feed section of a printer that uses rolled recording paper.

(Prior Art) A conventional printer of this type has a housing 1 as shown in FIG.
A paper feed section 2 is provided inside the paper feed section 2, and a roll recording paper 3 is provided inside the paper feed section 2.
was stored in this paper feed section 2.

According to this conventional paper feed section structure, the size of the paper feed section 2 is determined based on the recording paper 3 having a predetermined roll diameter. It was not possible to store rolled recording paper.

Therefore, newspaper companies that use printers continuously,
There was a problem in that the rolled recording paper 3 had to be loaded frequently into the paper feed section 2.

On the other hand, in order to solve this problem, if the paper feed section 2 of the printer is made larger so that it can accommodate recording paper whose diameter is sufficiently larger than the predetermined roll diameter, the casing 1 itself will also become larger.
In places where the printer is used less frequently, the problem arises that the installation space for the printer becomes larger than necessary.

In this case, it is conceivable to manufacture a printer having a paper feed section 2 of a size that corresponds to the user's request, but this would lead to the problem that the printer would have to be produced in small quantities and would be expensive.

(Problem to be Solved by the Invention) As described above, in the paper feed section structure of the printer, the size of the paper feed section that stores the roll of recording paper is determined based on the predetermined roll diameter of the recording paper. It has been decided,
Since it is not possible to store recording paper having a roll diameter larger than a predetermined roll diameter, there is a problem in that roll-shaped recording paper must be frequently loaded into the paper feed section in places where the printer is frequently used.

The present invention has been made in view of these conventional drawbacks, and it is possible to attach recording paper of a roll diameter desired by a user using a printer, and to attach the minimum required diameter according to the roll diameter of the recording paper. The purpose of the present invention is to provide a paper feed section structure for a printer that allows the printer to be installed in a space.

Structure of the Invention - (Means for Solving the Problems) The structure of the paper feed section of the printer of the present invention is based on a state in which the leading end holds a roll of recording paper and the leading end protrudes from the printer casing. The holder includes a holder whose end portion is fixed to the casing, and the holder includes a holder that attaches the proximal end to the casing at a plurality of positions with different amounts of protrusion of the distal end from the casing. The configuration includes a fixing means for fixing.

(Function) In the present invention, when the fixing position of the proximal end of the holder relative to the printer casing is changed using the fixing means, the amount of protrusion of the distal end of the holder from the printer casing increases or decreases. The shaft of the recording paper is 11771 depending on the amount of protrusion of the leading edge.
Move away from or close to the body.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 6.

1 to 4 are diagrams for explaining the first embodiment.

In the figure, 10 is the housing of the printer, 11 is a roll of recording paper,
12 is a spool shaft, and 13 is a holder. The spool shaft 12 and the holder 13 constitute a paper feeding section of the printer.

As shown in FIG. 1, a pair of holders 13, 13 are provided on the back surface 15 of the housing 10 with a predetermined distance therebetween.

This holder 13 is made of a metal plate, and as shown in FIG.
A U-shaped notch 20 is formed upward.

In addition, the base end 22 has a plurality of slits (fixing means) 2.
4 are formed parallel to each other downward.

On the other hand, a hole 26 into which the proximal end 22 side of the holder 13 is inserted is formed in the rear surface 15 of the casing. Then, the base end 22 of the holder 13 is inserted into the hole 26 (the holder 13 indicated by a solid line in FIG. 2), and the holder 13 is moved further downward (in the direction of the arrow) into one of the plurality of slits 24. Hole 2
6 is attached to the rear surface 15 of the housing by inserting the peripheral edge part 28 of the holder 1 (shown by a dashed line in FIG.
3).

Also, a spool n12 in which the recording paper 11 is wound into a roll is provided.
is held at both ends by the tip 18 of the holder 13,
It is arranged on the rear surface 15 side of the housing.

Next, the operation of the above structure will be explained.

When the roll diameter of the rolled recording paper 11 held on the spool shaft 12 is small, as shown in FIG.
The hole peripheral edge 28 is inserted into the slit 24a at a position where the amount of protrusion of the holder tip 18 from the holder 5 is small. The spool shaft 12 is now positioned close to the rear surface 15 of the housing, and the rolled recording paper 11 is positioned close to the rear surface 15 of the housing.

On the other hand, the rolled recording paper 11 held on the spool @12
When the diameter of the roll is large, the peripheral edge portion 28 of the hole is inserted into the slit 24b at a position where the amount of protrusion of the tip end portion 18 of the holder is large, as shown in FIG.

The spool shaft 12 is now positioned apart from the rear surface 15 of the casing, and recording paper 11 with a large roll diameter can be attached.

In this way, in the paper feed section structure of this example, by changing the fixing position of the base end 22 of the holder 13, the recording paper 11 of a desired roll diameter can be fed into the printer 10 within the minimum necessary space. It can be attached to.

FIG. 5 is a perspective view of a printer illustrating a second embodiment of the present invention.

In the paper feed section structure of this example, the base end 22A of the holder 13A is formed into a rod shape, and both side surfaces 3 of the printer 10A are
It is slidably inserted in the direction of the arrow into the arm 31 which is formed to have a diameter of 0.30 mm. In addition, a plurality of holes 35 into which screws (fixing means) 34 are inserted are formed in the base end portion 22A at predetermined intervals in the longitudinal direction. On the other hand, the housing 10A
A screw hole (not shown) into which a screw 34 is screwed is provided on the side. Therefore, the protrusion of the distal end portion 18 from the back surface 15 of the casing depends on which of the plurality of holes 35 formed in the proximal end portion 22A the screw 34 is inserted to screw the proximal end portion 22A onto the casing 10A. You can increase or decrease the amount. Other configurations and effects are similar to those of the first embodiment.

FIG. 6 is a perspective view of a printer illustrating a third embodiment of the present invention.

The structure of the paper feed section in this example is the tip part 18B of the holder 13B.
It is formed into a box shape by a bottom plate 40, a back plate 41, and both side plates 42 and 42, and a part of the side plate 42 serves as the base end portion 22 similar to the first embodiment. Therefore, the tip 18
A roll of recording paper 11 without a spool shaft can be stored in B, and the attachment of the base end 22 to the printer housing 10 can be adjusted according to the diameter of the recording paper 11 by changing the position 1. The amount of protrusion of the tip portion 18B from the housing 10A can be increased or decreased.

[Effects of the Invention] As explained above, in the paper feed section structure of the present invention, by changing the fixed position of the base end of the holder relative to the printer housing, the position of the leading end that holds the roll recording paper can be adjusted to the printer. Since it can be moved away from or close to the housing, recording paper of various roll diameters can be held at the tip, and rolled recording paper can be mounted close to the printer regardless of the roll diameter. Therefore, the printer can be installed in the minimum necessary space.
