Abstract
The present invention provides a medium conveyance device whose reliability is enhanced. Namely, a roller conveyance section uses support parts to couple together an upper side shaft, which receives a first reaction force produced in accordance with a first contact-pressure force that urges first driven rollers toward first drive rollers, and a lower side shaft, which receives a second reaction force produced in accordance with a second contact-pressure force that urges second driven rollers toward second drive rollers. Because of this, the medium conveyance device of the present invention may cancel out the two reaction forces that cause an upper side guide and a lower side guide to bend in two bank note conveyance paths adjacent to one another.
Claims7
A medium conveyance device comprising:
- a first conveyance path that conveys a medium;
- first drive rollers that contact the medium and that cause the medium to move by rotation;
- first driven rollers, disposed opposing the first drive rollers across the first conveyance path, that contact the medium and rotate in accordance with the rotation of the first drive rollers;
- first contact-pressure portions that apply a first contact-pressure force that urges the first driven rollers toward the first drive rollers;
- a second conveyance path that is adjacent to the first conveyance path and conveys a medium;
- second drive rollers that contact the medium and that cause the medium to move by rotation;
- second driven rollers, disposed opposing the first driven rollers and also opposing the second drive rollers across the second conveyance path, that contact the medium and rotate in accordance with the rotation of the second drive rollers;
- second contact-pressure portions that apply a second contact-pressure force that urges the second driven rollers toward the second drive rollers;
- and
- support portions that couple a first reaction force receiving portion that receives a first reaction force produced toward the second conveyance path in accordance with the first contact-pressure force and a second reaction force receiving portion that receives a second reaction force produced toward the first conveyance path in accordance with the second contact-pressure force.
