when a front end of a conveyed sheet abuts against the guide member and pushes the guide member, the guide member retracts from a projecting position into the space on the side of the pair of rotating bodies and guides the front end of the conveyed sheet to the nip portion of the pair of the rotating bodies.
2. The sheet conveying apparatus according to claim 1, wherein the guide member is located at the projecting position by its own weight.
3. The sheet conveying apparatus according to claim 1, wherein the first rotating bodies is made of metal and a surface of the first rotating bodies are subjected to blast processing, and the second rotating bodies is made of rubber.
4. An image forming apparatus has an image forming portion which forms an image on a sheet, the image forming apparatus comprising:
a plurality of first rotating bodies;
a shaft on which the first rotating bodies are provided;
a plurality of second rotating bodies provided at a lower side of the first rotating bodies, which pressure contact with the first rotating bodies to nip a sheet by a nip portion and to convey the sheet; and
a guide member loosely fitted on the shaft and disposed in a space on a side of a pair of rotating bodies of the first rotating bodies and the second rotating bodies, the guide member formed into a disk-like shape having a diameter larger than that of the first rotating bodies and a hole formed in a center of the guide member having a diameter larger than that of the shaft, and the guide member projecting toward the lower than the nip portion of the pair of the rotating bodies in a state where the sheet is not conveyed by the first and second rotating bodies, wherein
when a front end of a conveyed sheet abuts against the guide member and pushes the guide member, the guide member retracts from a projecting position into the space on the side of the pair of rotating bodies and guides the front end of the conveyed sheet to the nip portion of the pair of the rotating bodies.
5. The image forming apparatus according to claim 4, wherein the guide member is located at the projecting position by its own weight.
6. The image forming apparatus according to claim 4, wherein the first rotating bodies is made of metal and a surface of the first rotating bodies are subjected to blast processing, and the second rotating bodies is made of rubber.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A tuner control method for a broadcast reception system having a plurality of tuners, the method comprising:
determining, if a channel request is received from a user terminal, whether a tuner tuned to a channel indicated by the channel request exists;
connecting, if a tuner tuned to the channel exists, the tuner to the user terminal; and
providing broadcast data received by means of the tuner to the user terminal.
2. The method of claim 1, wherein the connecting of the tuner to the user terminal comprises:
sending a group share Identifier (ID) configured at the tuner tuned to the channel to the user terminal; and
supplying the broadcast data to at least one user terminal having the group share ID.
3. The method of claim 1, further comprising:
determining, if no tuner tuned to the channel exists, whether an idle tuner exists;
configuring, if an idle tuner exists, a group share Identifier (ID) at the idle tuner; and
sending the group share ID of the idle tuner to the user terminal
4. The method of claim 1, further comprising:
determining a priority of the user terminal; and
granting a tuner control right to the user terminal depending on the determined priority.
5. The method of claim 4, wherein the priority is determined by one of order of time when the channel request is received and type of the user terminal
6. The method of claim 4, further comprising, after the connecting of the tuner to the user terminal:
receiving a request for a channel change from the user terminal;
determining if the user terminal includes the tuner control right; and
changing to the requested channel if the terminal includes the tuner control right.
7. The method of claim 1, further comprising, after the connecting of the tuner to the user terminal:
receiving a request for a channel change from a second user terminal;
determining if a priority of the second user terminal is greater than a priority of the user terminal currently connected to the tuner; and
switching to the requested channel if the priority of the second user terminal is greater than the priority of the user terminal currently connected to the tuner.
8. The method of claim 7, wherein the priority is determined by one of order of time when the channel request is received and type of the user terminal
9. A tuner control apparatus, the apparatus comprising:
a tuning unit including at least one tuner for tuning to a channel; and
a control unit for determining, if a channel request is received from a user terminal, whether a tuner tuned to a channel indicated by the channel request exists, for connecting, if a tuner tuned to the channel exists, the tuner to the user terminal, and for providing broadcast data received by means of the tuner to the user terminal.
10. The apparatus of claim 9, wherein the control unit sends a group share Identifier (ID) configured at the tuner tuned to the channel to the user terminal and supplies the broadcast data to at least one user terminal having the group share ID.
11. The apparatus of claim 10, wherein the control unit determines, if no tuner tuned to the channel exists, whether an idle tuner exists, configures, if an idle tuner exists, a group share ID at the idle tuner, and sends the group share ID of the idle tuner to the user terminal.
12. The apparatus of claim 9, wherein the control unit determines a priority of the user terminal and grants a tuner control right to the user terminal depending on the determined priority.
13. The apparatus of claim 12, wherein the priority is determined by one of order of time when the channel request is received and type of the user terminal
14. The apparatus of claim 12, wherein the control unit, after connecting the tuner to the user terminal, receives a request for a channel change from the user terminal, determines if the user terminal includes the tuner control right, and changes to the requested channel if the terminal includes the tuner control right.
15. The apparatus of claim 9, wherein the control unit, after connecting the tuner to the user terminal, receives a request for a channel change from a second user terminal, determines if a priority of the second user terminal is greater than a priority of the user terminal currently connected to the tuner, and switches to the requested channel if the priority of the second user terminal is greater than the priority of the user terminal currently connected to the tuner.
16. The apparatus of claim 15, wherein the priority is determined by one of order of time when the channel request is received and type of the user terminal
