摘要:
An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.

An image reading apparatus which is capable of performing accurate shading correction with simple arrangement while preventing a reference member from being scratched and preventing paper powder and the like dust from being deposited on the reference member. The image reading apparatus includes an image reading unit in which a contact glass guides an original on an image reading location. The contact glass is held by a glass holding member. A line image sensor reads the image on the original conveyed on the image reading location, through the contact glass. The image reading unit further includes a reference member whose image is readable by the image sensor, and a moving mechanism to move the image sensor so as to enable the image sensor to alternatively read the original and a reference surface of the reference member.

A camera comprises a lens unit and a camera body to which the lens unit is attached by a rotational operation. The camera body is provided with terminals including a specific terminal. Arrangement of the specific terminal is different from that of the other terminals. In detaching the lens unit from the camera body, the specific terminal is adapted to be disconnected earlier relative to the other terminals while the other terminals are connected. After the disconnection of the specific terminal has been detected, the other terminals are set to high impedance.

An object is to improve the operational reliability of a gas turbine by suppressing thermal stress and thermal deformation acting on the rotor of the gas turbine. The gas turbine has a rotor shaft constructed by arranging, in an axial direction in turn, a plurality of discs each having a plurality of combustion gas-driven moving blades annularly arranged on the peripheral portion and spacers arranged between the discs, and is characterized in that gap portions are formed between a region, on the rotor shaft center portion side, of the above-mentioned discs facing the spacers and spacers adjacent thereto, contact surfaces are formed both of which contact on both a region, on the rotor peripheral side, of the above-mentioned discs facing the spacers and adjacent spacers thereto, and a third flow path leading fluid to the above-mentioned gap portions is provided.

A stabilized transmitter includes a gain converter that varies its gain according to an electrical signal; a power amplifier that amplifies a high-frequency signal passed through the gain converter; and a compensator having a temperature sensor which detects the temperature of the power amplifier for producing from a detection result of the temperature sensor the electrical signal applied to the gain converter so as to thereby to compensate for variations of the gain of the power amplifier caused by temperature variations. The compensator is adjusted in advance so that the gain of the power amplifier at a reference temperature becomes a predetermined value.
