  • Publication number: 20100329665
    Abstract: A diaphragm control apparatus in a camera body includes a stepping motor; a lead screw thereof, wherein a slider is driven by the lead screw; a position detector; and a controller. When driving the stepping motor by a predetermined number of steps in a direction to move the slider away from an origin position, the controller detects the slider position before driving the stepping motor stepwise as the origin position via the position detector, and thereafter detects a stepping position of the slider to compare the stepping position with the origin position each time the stepping motor is driven by one step, and counts the number of steps based from the moment at which the stepping position of the slider exceeds a predetermined position in the direction to move the slider away from the origin position against the biasing force of the resilient biaser.

  • Publication number: 20100329658
    Abstract: A diaphragm control apparatus in a camera body includes a stepping motor, a lead screw thereof, wherein a slider is driven by the lead screw, a position detector, and a controller. When the stepping motor is in a free state, the slider allows a diaphragm operatively-associated rod to move to an initial position. The controller detects the slider origin position when the stepping motor is in the free state and drives the stepping motor stepwise to move the slider away from the origin position against a biasing force of a resilient biaser, and drives the stepping motor stepwise to move the slider toward the origin position while detecting the slider position; and sets an initial excitation pattern of the stepping motor upon a distance from the detected slider position to the origin position becoming less than a slider moving distance for one step of the stepping motor.

  • Publication number: 20080242223
    Abstract: An information communication system for transmitting position data includes a short range wireless communication system for transmitting the position data between a cellular telephone and a digital still camera. There is a communication subsystem for communication, and for transmitting an enable signal between the cellular telephone and the digital still camera to establish the short range wireless communication in response to operation to instruct retrieval of the position data. The enable signal is transmitted while the short range wireless communication is inactive, and establishes the short range wireless communication. A controller terminates the short range wireless communication after the position data is transmitted through. Preferably, the digital still camera outputs the enable signal and receives the position data. Also, in the communication subsystem, public accessible wireless LAN network is used with the digital still camera, and connected with a mobile communication network by a gateway device.

  • Publication number: 20080232780
    Abstract: A camera system consists of a primary digital camera and at least a secondary digital camera. When a shutter button of the primary digital camera is operated after it is set up with conditions for successive shots, the primary digital camera produces a composite sound signal by encoding data of the set conditions for successive shots and superimposing the encoded data on a sound signal, and outputs the composite sound signal through a speaker. The secondary digital camera catches the composite sound signal through a microphone, and decodes the composite sound signal to detect the data of the set conditions for successive shots. According to the set conditions for successive shots, the primary and secondary cameras execute a synchronized successive shot process.

  • Publication number: 20080000249
    Abstract: An indoor unit of an air conditioner wherein a pipe retaining member retaining auxiliary piping connected to a heat exchanger is disposed near both a lateral side and an underside of a bottom frame. The pipe retaining member is bent in an L-shape, and its short plate is exposed on the underside of the bottom frame. The pipe retaining member can be removed only by slightly separating a lower part of the bottom frame from a wall in the fixed state of the indoor unit to the wall. Since the heat exchanger can be separated from the bottom frame without disconnecting the auxiliary piping from communication piping, maintenance work such as washing of the heat exchanger is efficiently performed without requiring much time and effort for separating the auxiliary piping from the communication piping.
