摘要： An information processing apparatus includes a control unit and an operation unit. The control unit is configured to generate image data for image display. The operation unit includes a display unit, and is configured to display a screen on the display unit based on the image data generated by the control unit and to accept user operation. The control unit executes first processing for identifying, based on a state of signal output from the operation unit, whether a malfunction has occurred in one of the control unit and the operation unit. The operation unit executes, independently of the first processing by the control unit, second processing for identifying, based on a state of signal output from the control unit, whether the malfunction has occurred in the control unit or in the operation unit.

摘要： A lens apparatus that can secure a necessary lens moving distance while avoiding growing in size and that is able to firmly hold a lens. The lens apparatus comprises a first lens group holding member, a second lens group holding member, an exterior cylinder disposed on an outer peripheral side of the first lens group holding member, a first cam cylinder disposed to be rotatable around an optical axis and movable in an optical axis direction corresponding to a rotation angle, a guide cylinder having a diameter fitting portion rotatably holding the first cam cylinder around the optical axis, and a second cam cylinder. The exterior cylinder does not have a cam groove or a guide groove for guiding another member, and is driven to a position at which part of the exterior cylinder is exposed to an outside corresponding to a rotation angle of the second cam cylinder.

摘要： A CPU of an image forming apparatus controls, according to establishment of a sleep change condition, a MAC/PHY in a network unit to change the image forming apparatus from a link-up state to a link-down state. The CPU controls the image forming apparatus to change from a normal mode to a deep sleep mode. A CPU of the network unit controls, according to the change of the image forming apparatus from the normal mode to the deep sleep mode, the MAC/PHY to change the link-down state of the image forming apparatus to the link-up state. The CPU controls the MAC/PHY to transmit a MAC address necessary for causing the image forming apparatus to participate in VLAN to a switching hub.

摘要： A vibration wave motor comprises a vibrator including a piezoelectric element and a vibrating body, a friction member including a first surface configured to come into contact with the vibrator, and a second surface, which is a surface on the opposite side of the first surface, the vibrator and the friction member moving relative to each other in a driving direction by a vibration generated by the vibrator, a supporting member configured to support the friction member on the second surface side; and a pressure member configured to bring the vibrator and the friction member into pressure contact with each other. A fixing portion configured to fix the friction member to the supporting member is provided in the friction member. The vibrator can move to a position where at least part of the vibrator and the fixing portion overlap each other in a pressure direction of the pressure member.

摘要： An ultrasonic motor includes a vibrator to which a piezoelectric element is fixed and a friction member having a frictional contact surface in contact with the vibrator. A pressurizing member pressurizes the vibrator toward the friction member using a resilient force of a coil spring. A pressurizing force setting unit transmits a driving force of a pressurizing force setting motor to a holding member and then sets the pressurizing force by altering an amount of deflection of the coil spring depending on the relative position of the holding member with respect to the pressurizing member. The friction member is driven relative to the vibrator by an elliptic vibration of the vibrator in a state where the projections provided on a vibration plate are brought into pressurized contact with the frictional contact surface of the friction member by the pressurizing force.
