Abstract

Provided is an inexpensive and lightweight carrying mechanism in which side frames and a guide plate are not required to be formed separately and assembled and a small number of components are required. A pair of right and left side frames ( 2 a, 2 b ) and a medium guide ( 3 ) are integrally formed to form a frame structure body ( 1 ). On one surface side of the medium guide ( 3 ) of the frame structure body ( 1 ), a carrying belt ( 8 ) for carrying a medium is disposed, and on the other surface side of the medium guide ( 3 ), a driven roller ( 10 ) for holding the medium between the carrying belt ( 8 ) and itself is disposed.

First claim

The invention claimed is:

1. A medium carrying mechanism comprising:
side frames;
a conveyance section disposed inside the side frames, the conveyance section including a drive shaft that rotates by being driven from outside the side frames, the drive shaft being supported by the side frames;
a first medium guide that guides a medium conveyed by the conveyance section, the side frames and the first medium guide being integrally formed, the side frames being formed at each of two opposite ends of the first medium guide, and the conveyance section being disposed on one face of the first medium guide;
a second medium guide that guides the medium conveyed by the conveyance section, the second medium guide being separate from the first medium guide, and the second medium guide is disposed so as to extend from the first medium guide; and
a gripping section provided on another face of the first medium guide and grips a medium between the gripping section and the conveyance section.

2. The medium carrying mechanism of claim 1 , wherein
the conveyance section comprises a conveyance roller, and
the gripping section comprises a following roller.

3. The medium carrying mechanism of claim 1 , wherein:
the gripping section comprises a following roller,
the conveyance section comprises a conveyor drum that has a larger diameter than the following roller,
the first medium guide has a shape so that the one face is a circular arc shaped inner peripheral face of the first medium guide,
the conveyor drum is disposed such that an outer peripheral face of the conveyor drum faces the circular arc shaped inner peripheral face of the first medium guide, and
the following roller is disposed on a first medium guide side.

4. The medium carrying mechanism of claim 3 , wherein a size of the inner peripheral face of the first medium guide is configured such that the inner peripheral face of the first medium guide faces about ⅓ of the outer peripheral face of the conveyor drum.

5. The medium carrying mechanism of claim 1 , wherein the drive shaft directly contacts the side frames so as to be supported by the side frames.

6. The medium carrying mechanism of claim 5 , wherein the conveyance section further comprises a conveyor drum disposed upon the drive shaft.

7. The medium carrying mechanism of claim 6 , wherein the conveyor drum is in direct contact with the drive shaft so as to be supported by the drive shaft.

8. The medium carrying mechanism of claim 1 , wherein the drive shaft penetrates through the side frames.

9. The medium carrying mechanism of claim 8 , wherein the conveyance section comprises a conveyor drum disposed upon the drive shaft.

10. The medium carrying mechanism of claim 9 , wherein the conveyor drum is in direct contact with the drive shaft so as to be supported by the drive shaft.

11. A medium carrying mechanism comprising:
side frames;
a conveyance section disposed inside the side frames;
a first medium guide that guides a medium conveyed by the conveyance section, the side frames and the first medium guide being integrally formed, the side frames being formed at each of two opposite ends of the first medium guide, and the conveyance section being disposed on one face of the first medium guide;
a second medium guide that guides the medium conveyed by the conveyance section, the second medium guide being separate from the first medium guide, and the second medium guide has a circular arc shaped inner peripheral face; and
a gripping section provided on another face of the first medium guide and grips a medium between the gripping section and the conveyance section.

12. The medium carrying mechanism of claim 11 , wherein the circular arc shaped inner peripheral face of the second medium guide is for guiding a medium.

13. The medium carrying mechanism of claim 11 , wherein
the conveyance section comprises a conveyance roller, and
the gripping section comprises a following roller.

14. The medium carrying mechanism of claim 11 , wherein:
the gripping section comprises a following roller,
the conveyance section comprises a conveyor drum that has a larger diameter than the following roller,
the first medium guide has a shape so that the one face is a circular arc shaped inner peripheral face of the first medium guide,
the conveyor drum is disposed such that an outer peripheral face of the conveyor drum faces the circular arc shaped inner peripheral face of the first medium guide, and
the following roller is disposed on a first medium guide side.

15. The medium carrying mechanism of claim 14 , wherein a size of the inner peripheral face of the first medium guide is configured such that the inner peripheral face of the first medium guide faces about ⅓ of the outer peripheral face of the conveyor drum.

16. The medium carrying mechanism of claim 11 , wherein the conveyance section includes a drive shaft that rotates by being driven from outside the side frames, the drive shaft directly contacting the side frames so as to be supported by the side frames.

17. The medium carrying mechanism of claim 16 , wherein the conveyance section further comprises a conveyor drum disposed upon the drive shaft.

18. The medium carrying mechanism of claim 17 , wherein the conveyor drum is in direct contact with the drive shaft so as to be supported by the drive shaft.

19. The medium carrying mechanism of claim 11 , wherein the conveyance section includes a drive shaft that rotates by being driven from outside the side frames, the drive shaft penetrates through the side frames.

20. The medium carrying mechanism of claim 19 , wherein the conveyance section comprises a conveyor drum disposed upon the drive shaft.

21. The medium carrying mechanism of claim 20 , wherein the conveyor drum is in direct contact with the drive shaft so as to be supported by the drive shaft.
