Abstract
Official abstract text for this publication.
A medium supplying apparatus with a detachable rolled medium is provided. In the medium supplying apparatus, the rolled medium is fed to a far side of a setting-and-removing direction of the rolled medium. The medium supplying apparatus includes a plurality of guide members configured to guide the rolled medium when the rolled medium is set. The guide members include at least one contact member which at least partially contacts only a lower outer periphery of the rolled medium and at least one auxiliary member which does not contact the outer periphery of the rolled medium. The contact member and the auxiliary member are connected at a base via the same rotary shaft. The auxiliary member is shorter than the contact member in a medium feeding direction, and is disposed in parallel with the contact member.
First claim
Opening claim text (preview).
The invention claimed is: 1. A medium supplying apparatus with a detachable rolled medium configured to be fed to a far side of a setting-and-removing direction of the rolled medium, the medium supplying apparatus comprising: a plurality of guide members configured to guide the rolled medium when the rolled medium is set, wherein the guide members include at least one contact member configured to at least partially contact only an outer periphery of the rolled medium and at least one auxiliary member configured not to contact the outer periphery of the rolled medium, wherein the contact member and the auxiliary member are connected at a base via a same rotary shaft, the auxiliary member is shorter than the contact member in a medium feeding direction, and the auxiliary member is disposed in parallel with the contact member. 2. The medium supplying apparatus according to claim 1 , wherein the guide members include at least one second auxiliary member configured not to contact the rolled medium above the fed rolled medium. 3. The medium supplying apparatus according to claim 2 , wherein the second auxiliary member includes an opening penetrating from an upper side to lower side of the second auxiliary member. 4. An image forming apparatus comprising the medium supplying apparatus according to claim 1 . 5. A medium supplying apparatus with a detachable rolled medium configured to be fed to a far side of a setting-and-removing direction of the rolled medium, the medium supplying apparatus comprising: a plurality of guide members configured to guide the rolled medium when the rolled medium is set, wherein the guide members include at least one contact member configured to at least partially contact only an outer periphery of the rolled medium and at least one auxiliary member configured not to contact the outer periphery of the rolled medium, wherein the contact member and the auxiliary member are connected at a base via a same rotary shaft, the auxiliary member is shorter than the contact member in a medium feeding direction, and the auxiliary member is disposed non-parallel with the contact member. 6. The medium supplying apparatus according to claim 5 , wherein the auxiliary member is disposed having a predetermined angle with respect to the contact member. 7. The medium supplying apparatus according to claim 5 , wherein the guide members include at least one second auxiliary member configured not to contact the rolled medium above the fed rolled medium. 8. The medium supplying apparatus according to claim 7 , wherein the second auxiliary member includes an opening penetrating from an upper side to lower side of the second auxiliary member. 9. An image forming apparatus comprising the medium supplying apparatus according to claim 5 . 10. A medium supplying apparatus with a detachable rolled medium configured to be fed to a far side of a setting-and-removing direction of the rolled medium, the medium supplying apparatus comprising: a plurality of guide members configured to guide the rolled medium when the rolled medium is set, wherein the guide members include at least one contact member configured to at least partially contact only an outer periphery of the rolled medium and at least one auxiliary member configured not to contact the outer periphery of the rolled medium, wherein the contact member and the auxiliary member are connected at a base via a same rotary shaft, the auxiliary member includes an extension-and-contraction mechanism capable of extending and contracting. 11. The medium supplying apparatus according to claim 10 , wherein the guide members include at least one second auxiliary member configured not to contact the rolled medium above the fed rolled medium. 12. The medium supplying apparatus according to claim 11 , wherein the second auxiliary member includes an opening penetrating from an upper side to lower side of the second auxiliary member. 13. An image forming apparatus comprising the medium supplying apparatus according to claim 10 .
