Description

[Detailed Description of the Invention] The present invention relates to a ribbon replenishment case for replenishing a cartridge of endless ink ribbon (hereinafter referred to as 1-no-bon) used in a printing device such as a line printer.

Recently, a cartridge containing a ribbon has been installed in the printing device, simplifying the ribbon driving device and making it easier to replace the ribbon.

When replacing a ribbon that has consumed most of its ink, it is uneconomical to replace the entire cartridge that still has enough ink, so it is economical to continue using the cartridge and replace only the ribbon.

After removing the ribbon that has consumed ink from the cartridge, even if you try to store the ribbon directly into the cartridge, the ribbon will tend to collapse and protrude from the cartridge before it is fully stored, so it is difficult to store the entire ribbon. The task of doing so is difficult.

In order to improve the above-mentioned drawbacks, this proposal stores the ribbon in a replenishment case in advance, and when replacing the ribbon, removes the ribbon that has consumed ink from the cartridge, and then inserts the new ribbon into the cartridge together with the replenishment case. After the ribbon is inserted, the replenishment case is removed from the cartridge, and the ribbon can be easily inserted in the desired state.

An embodiment of the present invention will be explained with reference to the drawings.

In the embodiments shown in FIGS. 1 and 2, the case 1 is made of a material such as paper or plastic that is not uneconomical even if it is disposable, has two discontinuous parts 2 and 3, and has two slits 4. , 5 forming an annular slit.
Using a similar material, a discontinuous portion 2,
3 and a storage body 11 provided with a peripheral wall 10 having openings 12 and 13 corresponding to the openings 12 and 13, respectively.

The height of the peripheral wall 10 is slightly longer than the sum of the width of the beam bong 8 and the thickness of the bottom plate 7.

The case 1 is assembled by inserting the peripheral wall 10 into the slits 4 and 5 of the pressing plate 6 and abutting the pressing plate 6 against the bottom plate 7.
The ribbon 8 is housed in the space formed by the inside of the peripheral edge 10 and a portion of the ribbon 8 is exposed through the opening 12.13.

A film-like lid material (not shown) covers the ribbon 8 and is adhered to the back surface of the bottom plate 7 of the case 1.

In order to insert the ribbon 8 stored in the space 9 into the ribbon 8 storage section 15 of the cartridge 14 (FIGS. 3 to 5), remove the lid and store the ribbon 8 in the space 9 with the bottom plate 7 facing down. Cover the cartridge 14 from above the case 1, where the bong 8 is visible from above, so that the entire circumferential wall 10 formed on the bottom plate 7 of the case 1 is inserted into the housing part 15, and in this state, remove the cartridge 14 and the case 1. Turn it over and position it so that the case 1 is on top and the cartridge 14 is on the bottom.

At this time, the ribbon 8 exposed from the opening 12.13 is held between the drive gear 16 and the idle gear 17,
The ribbon 8 is held between a spring 18 that delays pulling out of the ribbon 8 from the storage part 15 and the inside of the peripheral wall of the cartridge 14.

Next, when the case 1 is pulled up while pressing the outer edge 19 of the pressing plate 6 against the end surface of the peripheral wall of the cartridge 14, only the ribbon 8 is left behind and stored in the storage section 15 of the cartridge 14.

Finally, if the pressing plate 6 left on the cartridge 14 is removed, the insertion of the ribbon 8 is completed.

Other embodiments of the present invention are shown below.

As shown in FIGS. 6 and 7, the case 11 includes a pressing plate 6 □ in which a substantially C-shaped slit 41 is formed with both ends slightly spaced apart, and a slit 41 on the center line of a horseshoe-shaped bottom plate 71.
The storage body 11□ is provided with a peripheral wall 10□ integrally formed with a bottom plate 71 so as to form a cavity 91 in which the ribbon 8 is inserted.

In the case 1, the peripheral wall 101 is inserted into the slit 41 and the bottom plate 7 is inserted.
1 is assembled against the pressing plate 6 □, and the ribbon 8 is stored in a spiral shape from the opening 12 □ of the peripheral wall 101 in the space 91 formed by the pressing plate 6 □ and the peripheral wall 10 □. is partially exposed through the opening 121.

As shown in Figures 8 and 9, case 1□ has two channel shapes facing each other with a slight distance between them.
A pressing plate 62 formed with □, 5□, and two U-shaped bottom plates 7
On the center lines of 4° and 73, slits 4° and 52
It consists of storage bodies 11□, 113 which are vertically provided with peripheral walls 10□, 103 which are inserted therethrough in a substantially coincident manner.

Case h has peripheral walls 102 and 103 at slits 4□ and 5°.
are inserted, and the bottom plates 7□, 73 collide with the pressing plate 6□, and the peripheral walls 10°, 10. The ribbon 8 is assembled to form openings 12□, 13□ for the ribbon 8 between the opposite ends of the ribbon 8, and the ribbon 8 is placed in the space 9□ formed by the pressing plate 6° and the peripheral walls 10□, 103. The ribbon 8 is stored in an irregularly folded state, and a part of the ribbon 8 is exposed from the openings 12° and 13□.

As shown in FIGS. 10 and 11, the case 13 has a peripheral wall that almost coincides with and passes through L-shaped slits 43-53, which are opposed to each other in point-symmetrical positions so that the two angle shapes are slightly separated at both ends. 10,. A bottom plate 7 in which the bottom surfaces of the 105 are connected together. Storage body 1 formed perpendicular to
1. It consists of

The case 13 has the peripheral walls 10, . 10
5 are inserted into each other, the bottom plate is brought into contact with the pressing plate 63, and the opening 123.
Assemble the press plate 63 and the peripheral wall 10 to form 13□.
．． The ribbon 8 is stored in the space 93 formed by the ribbon 105 in an irregularly folded state, and a part of the ribbon 8 is exposed from the opening 123.13□.

To store the case 1t=12, 13 or insert the bong 8 into the cartridge 14, open the case 11 as described above.
, 1□, 13, and the cartridge 14 so that all of the peripheral walls 101, 10□ and io, , io, and 105 enter the storage section 15.
is placed on the cartridge 14, and then turned over and presses the pressing plates 6□, 6□, and 63 against the end surface of the peripheral wall of the cartridge 14, and the storage body 11. ．． 1
1° and 11, pull up the IL and place the ribbon 8 in the storage section 15.
Insert it into.

The present invention has a simple structure, so it can be produced at low cost and is easy to handle, and has the advantage of being able to reliably insert the ribbon in an irregularly folded state into the cartridge without pushing it down. .
