A display control system includes a first wireless device attached to a management target and storing first identification information for identifying the management target, a second wireless device installed at a predetermined position and storing second identification information, a reading apparatus, at least one processor, and at least one memory. The processor and memory are configured to estimate a located position of the management target based on reading results of the first identification information at a first reading time and the second identification information at a second reading time and cause a display apparatus to display an estimated area within which the management target is estimated to be located based on the located position. A magnitude of the estimated area is based on an amount of movement of the reading apparatus between the first reading time and the second reading time.

Display control system, information processing apparatus, and computer-readable medium

A process management system includes a management unit that manages section data that defines sections in a real space and process data that indicates an expected location, from among the sections, in which a management target is to be positioned at the time of completing a work process, a first wireless device that is attached to the management target and stores first identification information, at least one reading apparatus that is capable of reading identification information from a wireless device, and a determination unit that checks a location of the management target estimated based on a result of reading of the first identification information from the first wireless device against the expected location by variable granularity depending on type information associated with the management target to determine a status of the work process regarding the management target.

Process management system, method and information processing apparatus

An information processing apparatus operable to specify identification information of a communication object that a moving object that carries a reader apparatus holds: receives, from the reader apparatus, identification information read from a communication object near the reader apparatus, and a reading time thereof; stores, in a memory unit, association information that includes association of the received identification information and the reading time; and specifies the identification information of the communication object that the moving object holds based on the association information stored in the memory unit.

Information processing apparatus, information processing method, and computer-readable storage medium

A biological information measurement apparatus comprises: a light source which illuminates a measurement target with light; a light receiving portion which receives a light amount of reflected light of the light from the measurement target; and a selecting unit which, based on a light amount received by the light receiving portion at each of a plurality of wavelengths of the reflected light, selects a wavelength to be used to measure biological information from the plurality of wavelengths.

A transfer unit includes a reading unit to read an image on a sheet conveyed along a conveyance path, a first signal transmission member having a flat shape and is connected to the reading unit, and a relay member connected to the first signal transmission member. The relay member relays a signal from the first signal transmission member, and a second signal transmission member having a round shape and is connected to the relay member. The second signal transmission member leads into an apparatus body from an inner portion of the transfer unit in an axial direction of a first rotation shaft.

Image forming apparatus

To notify a residual life of a replaceable part at appropriate time on image quality required by the user. An image forming apparatus including: a replaceable part used for image formation; an output unit configured to output information indicating that a usage amount has reached a threshold; an input unit configured to input information; and a control unit configured to change the threshold in accordance with information about image quality input by the input unit.

Image forming apparatus and image forming system

An image forming apparatus includes a detection unit that detects information about a used amount of a unit, and a control unit that outputs information indicating that the unit is required to be replaced when the information about the detected used amount reaches a first predetermined threshold value, wherein the control unit changes the threshold value to a second threshold value according to information about the used amount when the unit is replaced.

Image forming apparatus and image forming system including a detection unit that detects information about a used amount of unit

An image forming apparatus includes a fixing unit that fixes an image, an obtaining unit that obtains information regarding conveying time taken to convey a recording material, a detection unit that detects information regarding an environment, and a control unit configured to determine, based on the information regarding the conveying time and the information regarding the environment, a timing at which the fixing unit is replaced.

Image forming apparatus that detects deterioration of a component and determines life of the component

The image forming apparatus includes a fixing portion, a temperature detection element, and a power control portion. The power control portion is capable of setting a first power supply control mode for supplying power according to the detected temperature for each one control cycle, a second power supply control mode for supplying power according to the detected temperature for each one control cycle and a third power supply control mode for supplying predetermined power, and switches, immediately before a leading edge of the recording material enters the fixing portion, a state of supplying the power in the first power supply control mode to a state of supplying the power in the second power supply control mode, and then switches the state of supplying the power in the second power supply control mode to a state of supplying the power in the third power supply control mode.

A toner pattern is detected by a color misregistration detection sensor to detect a duration of contact between a development roller and a photosensitive drum. A contact/separation motor for driving the development roller is accelerated or decelerated based on the detected duration of contact between the development roller and the photosensitive drum. This control enables shortening the duration of contact between the development roller and the photosensitive drum, thus reducing the shortening of their lifetime.

Process cartridges are driven by respectively corresponding DC brushless motors. In a cleaning sequence executed after image formation ends, the DC brushless motors operate according to the driving parameters such that acoustic operational noise decreases.

Cleaning control of image carrier in image forming apparatus

When a recording material is conveyed to a double surface conveying portion, a second conveying roller pair is forward driven to convey the recording material conveyed by a first conveying roller pair forward driven. A control portion performs control so that the driving of the second conveying roller pair is stopped and the second conveying roller pair is separated in timing in which the first conveying roller pair is switched from forward driving to reverse driving.

Image forming apparatus and sheet conveying apparatus

An image forming apparatus is provided which includes an image formation unit for forming images on a recording medium; a first transporting path for discharging a recording medium to a sheet discharge device; a longer second transporting path for reversing the transportation direction of the recording medium; a transporting path switching unit for switching between the first transporting path or the second transporting path; a setting unit for setting the discharge speed for discharging the recording medium from the first and second transporting paths to a recording sheet stacking unit, and also setting the reverse transportation speed; and a determining unit for determining whether or not the sheet discharge device has been connected to the image forming apparatus; wherein the setting unit sets a first discharge speed slower than the reverse transportation speed in the event that the sheet discharge device has not been connected, and otherwise sets a faster second discharge speed.
