A printing apparatus includes a control unit configured to perform control so as to apply a first driving voltage to a heat generation element to discharge ink from an orifice and then apply a second driving voltage to the heat generation element so as not to cause bubbling or discharging of ink. In this case, the control unit performs control to apply the second driving voltage before detection of a feature point on the waveform of a signal representing temperatures in a temperature drop process detected by the temperature detection element after application of the first driving voltage and along with the application of the first driving voltage based on a temperature detected by a temperature detection element.

The discharging state of an inkjet recording head can be detected. The head includes a passage communicating with a discharge port for discharging ink, a discharging heater provided in the passage for generating energy to discharge ink from the discharge port, and a detecting unit provided in the passage for detecting a temperature of ink that changes in accordance with heat energy generated by the detecting unit and a flow of ink in the passage. The method includes supplying power to the heater, subsequently applying a first pulse current to the detecting unit, then applying a second pulse current with a smaller pulse width, and measuring and comparing an output signal from the detecting unit with a threshold to measure the ink temperature.

There is disclosed a zoom lens barrel of inner focusing type, simplified in structure by the use of a surface wave motor. There are provided two biasing members of different biasing forces, in such a manner that the stator member of the surface wave motor can rotate with respect to the fixed tube member and the movable member of the surface wave motor rotates integrally with the stator member in the zooming operation. Such structure allows to dispense with a mechanical clutch for selecting the focusing or zooming operation.
摘要:
A lens barrel comprises a fixed barrel; a photographing lens which requires a first torque for driving the lens along the fixed barrel; and a surface wave motor including a fixed body and a moving body which is rotated relative to the fixed body by excitation for driving the lens. When the motor is not excited, a second torque is exerted between the moving body and the fixed body to prevent the relative rotation. The moving body is caused to rotate by a torque greater than the second torque. A friction generating device provided between the fixed barrel and the fixed body exerts a third torque to prevent relative rotation between the fixed barrel and the fixed body. The fixed body can rotate with respect to the fixed barrel only when the fixed body is caused to rotate by a torque greater than the third torque. A manual operation member drives the photographing lens by a manual operation; and a friction clutch provided between the manual operation member and the fixed body exerts a fourth torque. The manual operation member can rotate with respect to the fixed body only when caused to rotate by a torque greater than the fourth torque.
