Abstract
An exemplified object of the present invention is to provide a guide mechanism, paper feed control method, and image-forming device that can prevent a jam or image degradation from occurring. The guide mechanism of the present invention includes a guide part that guides continuous paper from a paper feeder part storing the continuous paper to a conveyor part while regulating a conveyance route of the continuous paper, and a driving part that drives the guide part and the paper feeder part to move relatively and automatically according to a storage amount of the continuous paper in the paper feeder part.
Claims9
A guide mechanism comprising:
- a guide part that guides continuous paper from a paper feeder part storing the continuous paper to a conveyor part, while regulating a conveyance route of the continuous paper;
- and
- a driving part that drives the guide part and the paper feeder part to relatively and automatically move according to a storage amount of the continuous paper in the paper feeder part.
A paper feed control method comprising the steps of:
- determining a space between a guide part that regulates a conveyance route of continuous paper, and a stack of the continuous paper;
- controlling a driving part to keep the space between the guide part and a stack of the continuous paper at a given distance;
- controlling the driving part under a specified condition to automatically set the space between the guide part and a stack of the continuous paper apart to a specified distance not less than the given distance;
- and
- determining whether a power has been turned on, wherein the specified condition is to determine that the power has been turned on.
A paper feed control method comprising the steps of:
- determining a space between a guide part that regulates a conveyance route of continuous paper, and a stack of the continuous paper;
- controlling a driving part to keep the space between the guide part and a stack of the continuous paper at a given distance;
- controlling the driving part under a specified condition to automatically set the space between the guide part and a stack of the continuous paper apart to a specified distance not less than the given distance;
- and
- determining whether paper has run out in a paper feeder part that stores the continuous paper, wherein the specified condition is to determine that the paper has run out.
A paper feed control method comprising the steps of:
- determining a space between a guide part that regulates a conveyance route of continuous paper, and a stack of the continuous paper;
- controlling a driving part to keep the space between the guide part and a stack of the continuous paper at a given distance;
- controlling the driving part under a specified condition to automatically set the space between the guide part and a stack of the continuous paper apart to a specified distance not less than the given distance;
- and
- determining whether a command to stop printing operation for the continuous paper has been provided, wherein the specified condition is to determine that the command to stop printing operation.
An image-forming device comprising:
- a paper feeder part that stores continuous paper;
- a conveyor part that conveys the continuous paper from the paper feeder part;
- a guide part that is provided between the paper feeder part and the conveyor part, and guides the continuous paper to the conveyor part, while regulating a conveyance route of the continuous paper;
- a driving part that drives the guide part and the paper feeder part to relatively move according to a storage amount of the continuous paper;
- and
- a printing part that forms an image on the continuous paper fed from the paper feeder part through the guide part.
