JPS6017328Y2 - Ink ribbon protection mechanism inside the ink ribbon cartridge - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a protection mechanism for protecting an ink ribbon from falling or twisting in an ink ribbon cartridge that stores an ink ribbon folded at a predetermined pitch.

The ink ribbon, which is folded and stored in the ink ribbon cartridge, is folded and stored with plenty of room in order to smoothly unwind it during use.

For this reason, when the ink ribbon cartridge is transported, the ink ribbon may fall or be twisted between folds due to vibration or impact.

As a result, there were drawbacks such as the occurrence of ink ribbon jams during use.

The present invention eliminates the above-mentioned drawbacks, and will be explained in detail below using examples.

FIG. 1 is a perspective view showing an embodiment of an ink ribbon protection mechanism in an ink ribbon cartridge according to the present invention.

In the figure, 1 is a cartridge body, and an endless ink ribbon 3 is folded at a predetermined pitch inside.
is stored.

Reference numeral 2 denotes a lid that engages with this cartridge body 1, and is provided with a plurality of through holes 2a.

Reference numeral 4 denotes a pressing portion whose shaft portion 4a is inserted into a bearing portion 5 of the cartridge body 1 and is rotatably supported.This pressing portion 4 is pressed by a spring 6, so that the ink drawn out from the cartridge body 1 is This gives appropriate tension to the ribbon 3.

7 is a protective member having a plurality of needle-like protrusions 7a.

With this configuration, the plurality of needle-like protrusions 7a of the protection member 7 pass through the through holes 2a of the lid 2 and are inserted between the folds of the ink ribbon 3, as shown in FIG.

Therefore, the needle-like protrusions 7a can prevent the ink ribbon 3 from falling or twisting due to vibration or impact during transportation.

FIG. 3 is a perspective view showing another embodiment of the ink ribbon protection mechanism in the ink ribbon cartridge according to the present invention.

8 is a protection member having a plurality of plate-like protrusions 8a.

With this configuration, the plurality of plate-like protrusions 8a of the protection member 8 are inserted between the folds of the ink ribbon 3 through the through holes 1a of the cartridge body 1, as shown in FIG.

Therefore, the plate-like protrusion 8a can prevent the ink ribbon 3 from falling or twisting due to vibration or impact during transportation.

Note that when installing the ink ribbon cartridge into a printer or the like, this protective member 7 is removed.

FIG. 5 is a plan view showing still another embodiment of the ink ribbon protection mechanism in the ink ribbon cartridge according to the present invention, in which the protection members 8 are inserted into both sides of the cartridge body 1.

As explained above in detail, the ink ribbon protection mechanism in the ink ribbon cartridge according to the present invention prevents the ink ribbon from falling or being twisted even if vibration or impact is applied to the ink ribbon cartridge. It has the effect of disappearing.
