AI Technical Summary

Benefits of technology

The patent is about a system that reduces the amount of electricity used by motors in a steady state. It does this by setting the load condition of a sheet of material conveyed by a roller, based on the type of sheet and the speed at which it is conveyed. The technical effect of this system is to provide more efficient use of electricity, which can save money and increase efficiency in production.

Problems solved by technology

However, in the technique disclosed in Unexamined Japanese Patent Publication No. 2002-159196, since the conveying roller is driven only by the DC brushless motor in the steady state, a problem arises in that consumption power cannot be suppressed by the optimization of the consumption current of the stepping motor and the DC brushless motor.
In the technique disclosed in Unexamined Japanese Patent Publication Nos. 2006-039095, 2006-017988, and 2007-058082, a problem arises in that the consumption power of two motors is not considered.

first embodiment

[0026]FIG. 1 is a cross-sectional view illustrating a schematic configuration of the image forming apparatus. The image forming apparatus 100 includes a controller 110, an operation panel 120, an image reader 130, an image former 140, a fixer 150, a feeder 160, and a sheet conveyor 170.

[0027]The controller 110 includes a Central Processing Unit (CPU) and various memories and performs control for each component or various calculation processes in accordance with a program.

[0028]The operation panel 120 includes a touch panel, ten keys, a start button, and a stop button and is used to display various pieces of information and to input various instructions.

[0029]The image reader 130 includes a light source such as a fluorescent lamp and an imaging device such as a Charge Coupled Device (CCD) image sensor. The image reader 130 applies light from a light source to a document set at a predetermined reading position, photoelectrically converts the reflected light by the imaging device, and ...

second embodiment

[0083]A second embodiment of the present invention will be described. The embodiment is different from the first embodiment as below. That is, in this embodiment, a test mode is performed in a case in which a special sheet not corresponding to any load condition of the table in which the STM set current and the DCBL drive current are registered for each load condition is conveyed and an image is formed thereon. Since the other points of this embodiment are the same as those of the first embodiment, a repetitive description will be omitted or simplified.

[0084]FIG. 13 is a flowchart illustrating an operation of the image forming apparatus. The flowchart can be performed according to a program by the controller 110 of the image forming apparatus 100.

[0085]The controller 110 determines whether the sheet for forming the image thereon is the special sheet on the basis of the print job (S201).

[0086]When the sheet to form the image thereon is not the special sheet (S201: NO), the controller...

Abstract

A conveying driving device of the invention includes a first motor which transmits power to a drive shaft of a roller; a second motor which transmits power to the drive shaft along with the first motor at a torque smaller than that of the first motor; and a controller which sets each of drive current setting values of the first motor and the second motor so that a total value of a consumption current of the first motor and the second motor becomes minimal in a steady state in which the roller rotates at a constant setting speed.
