Abstract

Disclosed are a paper storage and a printer. The paper storage comprises: a warehouse body ( 20 ) for accommodating a medium, a medium outlet (A), and a roller ( 5 ) arranged on the storage body ( 20 ), wherein the medium outlet (A) is configured to discharge the medium accommodated in the storage body ( 20 ) after the medium passes by the roller ( 5 ), and an opening ( 224 ) opposite to the roller ( 5 ) is also arranged on a wall of the storage body ( 20 ), to allow an external medium processing device to match with the roller ( 5 ) through the opening ( 224 ) to process the medium. To replace the paper storage in a printer adopting such paper storage, the need for respective detachment of various parts of the paper storage, and the need for opening of the upper cover of the printer to load the paper roll are eliminated, thereby avoiding the problems of complex operations of replacing the paper roll and inconvenience in use.

First claim

The invention claimed is:

1. A paper storage comprising: a storage body ( 20 ) for accommodating a medium, a medium outlet (A), and a roller ( 5 ) arranged on the storage body ( 20 ), wherein the medium outlet (A) is configured to discharge the medium accommodated in the storage body ( 20 ) after the medium passes by the roller ( 5 ), and an opening ( 224 ) opposite to the roller ( 5 ) is provided on a wall of the storage body ( 20 ), to allow an external medium processing device to match with the roller ( 5 ) through the opening ( 224 ) to process the medium;
wherein the paper storage ( 20 ) comprises a chassis ( 22 ) and an upper cover ( 21 ), and the chassis ( 22 ) and the upper cover ( 21 ) are combined to form the medium outlet (A);
wherein the roller ( 5 ) is arranged on the upper cover ( 21 ) and the opening ( 224 ) is arranged on the chassis ( 22 ).

2. The paper storage of claim 1 , further comprising a paper tearing bar ( 23 ) located at the medium outlet (A) and arranged on the chassis ( 22 ).

3. The paper storage of claim 1 , wherein a guide member ( 25 ) configured to limit a position of the medium in a width direction is arranged in the storage body ( 20 ).

4. The paper storage of claim 1 , further comprising a clamping structure configured to lock the upper cover ( 21 ) and the chassis ( 22 ) together when the upper cover ( 21 ) is closed relative to the chassis ( 22 ).

5. The paper storage of claim 1 , wherein the upper cover ( 21 ) is pivoted with or detachably connected with the chassis ( 22 ).

6. The paper storage of claim 1 , wherein a gear ( 53 ) in a transmission connection with a driving mechanism of the external medium processing device is arranged at an axial end of the roller ( 5 ).

7. The paper storage of claim 1 , further comprising a connection structure configured to connect the storage body ( 20 ) with the external medium processing device.

8. A printer, comprising a base ( 1 ) and a detachable paper storage ( 2 ), the detachable paper storage comprises a storage body ( 20 ) for accommodating a medium, a medium outlet (A), and a roller ( 5 ) arranged on the storage body ( 20 ), wherein the medium outlet (A) is configured to discharge the medium accommodated in the storage body ( 20 ) after the medium passes by the roller ( 5 ), and an opening ( 224 ) opposite to the roller ( 5 ) is provided on a wall of the storage body ( 20 ), to allow an external medium processing device to match with the roller ( 5 ) through the opening ( 224 ) to process the medium;
wherein a printing head assembly ( 4 ) is arranged on the base ( 1 ), and the roller ( 5 ) of the detachable paper storage ( 2 ) is configured to match with a printing head ( 41 ) of the printing head assembly ( 4 ) at the opening ( 224 ) of the paper storage ( 2 ).

9. The printer of claim 8 , wherein the base ( 1 ) is provided with a driving mechanism configured to drive the roller ( 5 ) to rotate.

10. The printer of claim 8 , wherein the base ( 1 ) is provided with a concave portion ( 17 ) configured to position the paper storage ( 2 ).

11. The printer of claim 10 , wherein a first elastic element ( 8 ) declining toward the paper storage ( 2 ) is arranged in the concave portion ( 17 ) so that the paper storage ( 2 ) always trends to move away from the concave portion ( 17 ).

12. The printer of claim 8 , wherein a clamping structure configured to clamp the paper storage ( 2 ) and the base ( 1 ) together is arranged between the paper storage ( 2 ) and the base ( 1 ).

13. The printer of claim 8 , wherein a locking mechanism configured to lock the paper storage ( 2 ) is further arranged on the base ( 1 ), and the locking mechanism comprises a lock hook ( 322 ) configured to match with a core shaft ( 51 ) of the roller ( 5 ) on the paper storage ( 2 ) in a locking manner.

14. A printer, comprising a base ( 1 ) and a paper storage ( 2 ) detachably connected with the base ( 1 ), wherein
the paper storage ( 2 ) comprises a chassis ( 22 ) and an upper cover ( 21 ) which are pivoted with each other through a pivot shaft ( 211 ), wherein the upper cover ( 21 ) is rotatable to be opened or closed relative to the chassis ( 22 ), a roller ( 5 ) is arranged on the upper cover ( 21 ), and an opening ( 224 ) is arranged on the chassis ( 22 ),
a printing head assembly ( 4 ), a driving mechanism configured to drive the roller ( 5 ) to rotate, and a concave portion ( 17 ) configured to accommodate the paper storage ( 2 ) are arranged on the base ( 1 ),
a clamping slot ( 34 ) configured to clamp the pivot shaft ( 211 ) is arranged in the concave portion ( 17 ), and a lock hook ( 322 ) configured to lock a core shaft ( 51 ) of the roller ( 5 ) is arranged on the chassis ( 1 ),
wherein a space configured to accommodate a medium is formed between the upper cover ( 21 ) and the chassis ( 22 ) when the upper cover ( 21 ) is closed relative to the chassis ( 22 ), and the roller ( 5 ) matches with a printing head ( 41 ) of the printing head assembly ( 4 ) at the opening ( 224 ).
