Title: Sheet carrying roller, image reading device and image forming device
Inventor: NEMOTO AKIO
IPC: B65H9/14
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a sheet carrying roller, an image reading device and an image forming device, which reduce angular moment acting on a sheet, enhance accuracy in sheet carrying action, and are excellent in reliability. SOLUTION: The provision of a coating region 5 only in the vicinity of an area over the action line of back-tension Fb, thereby allows angular moment to act on a sheet to be reduced. Besides, it is recommended to enhance sheet carrying force by applying coating high in frictional coefficient. In this case, it may be much better that carrying force obtained by a portion to which coating is applied, is set to be higher than the force of back-tension Fb, and furthermore, carrying force caused by a portion to which no coating is applied, is set to be less than the force of back-tension-Fb. And furthermore, it may be much better that the outer diameter of a roller for a portion to be increased in sheet carrying force, is larger than the outer diameter of a roller for a portion not to be increased in carrying force.  Besides, in an image reading device, a reading means is provided, which allows the image of a document sheet to be read out while the document sheet is being carried by a sheet carrying roller.

Filed: 1988-03-07
Abstract: PURPOSE:To set appropriate printing process conditions with high probability by setting the printing process conditions based on two or more sets of agreed printing process information which are read by means of a sensor. CONSTITUTION:An original film 10 is normally carried from an edge part along a longitudinal direction on a carrying path P by means of a normal carrying part. When a data track 21 and a timing track 22 of the original film 10 pass right above the sensor 30, reading operation is started by sequentially reading the printing process information. The reading signal of the sensor 30 is sent to an information processing part and the normal carrying part normally carries the original film 10 and the reading operation is continued until read values agree at least twice or more. When at least two or more sets of read values agree, the printing process conditions re set based on said agreed read values. Thus, the appropriate printing process conditions can be set with high probability by simple constitution.
