The controller moves a movable body along a moving direction. A recording head and a detector are mounted on the movable body. The detector detects a detection target fixed to an ink receiving unit. The ink receiving unit receives an ink jetted from the recording head at a time of a flushing. The controller obtains, based on a signal from an encoder, a position of the movable body in a case that the detection target is detected by the detector during movement of the movable body. The controller determines a start timing of the flushing based on the obtained position of the movable body.

Image forming apparatus

There is provided a pulse generator generating a timing pulse based on a detection signal obtained from a detection signal outputting part configured to output the detection signal every time a motor rotates by a predetermined amount which has been previously set. The pulse generator includes: a time information calculating part, and a timing determining part. A time difference between a first calculating timing at which first time information is calculated and a second calculating timing at which second time information is calculated is longer than a time required for the motor to rotate by not less than an angle corresponding to a cogging distance.

Pulse generator

An electronic device includes a motor, a moving body on which a processing part is mounted, a rotary encoder, a memory; and a controller. The controller is configured to execute a detection process of detecting a position of the moving body based on an encoder signal, a control process including a first control of controlling movement of the moving body by controlling the motor and a second control of controlling a processing operation by the processing part in a constant speed movement section of the moving body, a determination process of determining a detection error of the position of the moving body generated in an acceleration section of the moving body based on information stored in the memory, and a correction process of correcting at least one of the first control and the second control.

Electronic device

A pulse generator includes: a position calculating part configured to calculate a position of a driving object, based on a detection signal of a detection signal outputting part; an adjusting amount calculating part configured to calculate at least one adjusting amount previously set so that a value of the at least one adjusting amount is periodically changed with respect to the position of the driving object; and a timing adjusting part configured to determine an output timing, at which the timing pulse is to be output, based on the at least one adjusting amount.

In a control system, a controller is configured to determine presence or absence of an obstructed area within the intermediate section, and control movement of the moving body in accordance with a selected one of controlling methods including a first and a second control methods. The first control method causes the moving body to move at a first constant speed in the processing section defined within the intermediate section and at a second constant speed faster than the first constant speed in at least a part of a non-processing section within the intermediate section and other than the processing section, the first control method being selected when the obstructed area is absent. The second control method causes the moving body to move at the first constant speed in the processing section and the non-processing section, the second control method being selected when the obstructed area is present.

Control system

A printing device is provided with a print head having a plurality of nozzles configured to eject ink droplets therefrom, a supplier configured to supply ink contained in a container to the print head, and a controller. The controller is configured to perform obtaining ink information having correlation with a height of a liquid surface of the ink contained in the container, obtaining subject image data representing an image to be printed, generating print data based on the subject image data, and causing the print head to eject ink droplets based on the print data. The generating includes adjusting the print data in accordance with the ink information.

Printing device, and non-transitory computer-readable recording medium therefor

A control system is configured such that a carriage that a processing head is mounted is driven by a motor and reciprocates. The motor is controlled by a controller. The controller reciprocates the carriage by selecting a control mode as a target mode based on temperature information related to temperature of the motor and controlling the motor in the target mode. The controller selects the target mode to be applied to the control of the motor for each of particular work units. The target mode is selected from a group of particular control modes. Each control mode in the group of particular control modes is a control mode in which a maximum temperature, which is estimated based on the temperature information, when the control of the motor using the selected control mode would be executed until the processing is completed, is less than a reference value.
