    摘要: Disclosed is a piezoelectric actuator drive unit that includes a piezoelectric actuator drive amplifier and a piezoelectric actuator drive unit power supply. Combinations of high and low signal levels of a first control signal, which controls the supply voltage and amplifier bias voltage of the piezoelectric actuator drive amplifier, and a second control signal, which controls the driving force of the piezoelectric actuator drive amplifier, are associated with a haptic feedback function, a receiver function for generating an audio output, and a speaker function for generating music or the like. Thus, the piezoelectric actuator drive unit, which vibrates a piezoelectric actuator, is adapted to the haptic feedback function, the receiver function, and the speaker function, and can optimize its power and drive amplifier characteristics.

    摘要: A fixing device includes an image surface side separating member that separates a recording medium from a fixing member; an image surface side conveyance guiding member arranged downstream of the image surface side separating member; a non-image surface side separating member that separates the recording medium from a pressing member; and a non-image surface side conveyance guiding member arranged downstream of the non-image surface side separating member. When the image surface side conveyance guiding member is rotated about its rotation axis so as to be opened or closed, the image surface side separating member is also rotated or slid so as to be opened or closed simultaneously. When the non-image surface side conveyance guiding member is rotated about its rotation axis so as to be opened or closed, the non-image surface side separating member is also rotated or slid so as to be opened or closed simultaneously.

    摘要: The fixing device using an electromagnetic induction heating (IH) method includes a fixing sleeve having a heating layer, a pressure roller to form a nip while contacting the fixing roller and rotate to drive the fixing sleeve, a temperature detector to detect a temperature on a circumference of the fixing sleeve, and an excitation coil provided near the fixing sleeve and configured to perform induction heating of the heating layer of the fixing sleeve based on the detection result from the temperature detector. The fixing device is configured to change a rotation speed of the fixing sleeve in a standby time during which the fixing sleeve, while rotating, is controlled to be heated so as to maintain a target temperature when a periodic temperature difference occurs on a circumference of the fixing rotary member and having a fluctuation amplitude larger than a predetermined value compared to the target temperature.

    摘要: A fixing device includes a magnetic flux generator, a rotating heat generation member, a magnetic flux adjuster, and a driver. The magnetic flux generator generates a magnetic flux. The rotating heat generation member rotates and applies heat to a recording medium bearing an image, and includes a heat-generating layer to generate heat using the magnetic flux generated by the magnetic flux generator. The magnetic flux adjuster is provided outside the rotating heat generation member, and decreases the magnetic flux applied to the heat-generating layer at least in a desired area in an axial direction of the rotating heat generation member. The driver changes the desired area by driving the magnetic flux adjuster in a direction of rotation of the rotating heat generation member.
