An imaging apparatus includes a diaphragm unit configured to adjust an amount of incident light on an image sensor, a correction unit configured to perform a correction of an image signal that corresponds to driving of the diaphragm unit, and a control unit configured to control the diaphragm unit and the correction unit. The correction unit includes at least a first state for performing a correction of the image signal when it can be determined that the diaphragm unit is not being driven by the control unit and a second state for not performing a correction of the image signal or for performing a correction of the image signal weaker than that performed in the first state when it can be determined that the diaphragm unit is being driven by the control unit.

A color combining optical system includes a first polarization splitting surface for light in a first wavelength range, and a second polarization splitting surface for light in a second and third wavelength range. The first polarization splitting surface guides illumination light in the first wavelength range to a first liquid crystal display (LCD) element and guides image light reflected from the first LCD element to a direction different from the illumination light. The second polarization splitting surface separates illumination light in the second and third wavelength range from each other, guides them to a second and third LCD element, respectively, and combines image light reflected from the second LCD element with image light reflected from the LCD element to guide combined light to the first polarization splitting surface which combines the image light reflected from the first LCD element with the combined light.

A winding apparatus for use in a copier, a printer, and other devices for ejecting a printed sheet in a rolled form of a cylinder without having a core includes a gripping mechanism for gripping the leading end of a sheet when the sheet is rolled into cylindrical form. The gripping mechanism is disposed on a cylindrical member provided to each of both ends of the sheet in a direction orthogonal to a conveyance direction of the sheet and moving with the conveyance of the sheet. The on and off states of gripping to the leading end of the sheet can be controlled. The gripping mechanism is turned to the off state, and the cylindrical member is retracted from the sheet.

In an electronic image pickup apparatus, if a mode used and some of setting values of additional functions are changed, a camera control microprocessor computes the number of images that can be captured on the basis of a current consumption integrated value that has been computed by a current integrating unit and stored in a storage unit, updates data of the number of images that can be captured using the computation result, and performs control processing so as to cause a display unit to display the updated data.

A movable body apparatus includes a vibratory system, a vibration detecting portion, a driving portion, and a controlling portion. The vibratory system has a resonance frequency and a movable body capable of being reciprocally and rotatably vibrated. The vibration detecting portion detects a vibration condition of the movable body. The driving portion drives the vibratory system with a drive signal. The controlling portion regulates the drive signal supplied to the driving portion. The controlling portion regulates a driving frequency of the drive signal so that a delay phase difference between the drive phase of the drive signal and the vibration phase of the vibratory system obtained from detection result of the vibration detecting portion, both obtained when the vibratory system is vibrated at a predetermined frequency, is maintained.

An optical system includes a first optical element and a second optical element on at least one of an enlargement side and a reduction side relative to a point P at which a light axis and a paraxial chief ray intersect. Each of the first optical element and second optical element is composed of a solid material having a refractive light incident surface and a refractive light emergent surface. The optical system satisfies the following conditional expressions: ΔθgF1>0.0272, ΔθgF2

An amount-of-developer regulating apparatus configured to restrict the amount of developer carried on a developer bearing member. The amount-of-developer regulating apparatus includes a flexible developer amount regulation member having a contact portion configured to contact with a developer bearing member, and first and second holding portions configured to hold the developer amount regulation member and to contact with the developer amount regulation member at further upstream and further downstream in a direction where the developer bearing member is rotationally moved than the contact portion. With a pressure distribution of the contact portion as to the developer bearing member, there are a plurality of local maximum values in the direction where the developer bearing member is rotationally moved. Thus, the apparatus can be reduced in size, and also image concentration unevenness after long-term use can be prevented.

An apparatus is configured to charge an image bearing member in a charging section, develop an electrostatic image formed on the image bearing member, and transfer a toner image formed on the image bearing member to a transfer medium in a transfer section. The apparatus includes a charging auxiliary apparatus for changing a charge amount of toner on the image bearing member. The charging auxiliary apparatus includes a charging auxiliary member contacting with the image bearing member downstream of the transfer section and upstream of the charging section and a voltage applying device to apply a voltage to the charging auxiliary member. The apparatus includes a first detector to detect a current flowing in the charging auxiliary member during a period of non-image formation when the voltage is applied to the charging auxiliary member, a second detector to detect information regarding a toner density in the developing apparatus, and a control device to control toner supply to the developing apparatus based on detection results of both the detectors.
