摘要： An airflow rate sensor is provided with a through hole, and a detection unit is disposed inside the through hole. The airflow rate is calculated based on the output voltage resulting from the temperature difference and the like caused in the detection unit by the air flowing through the through hole. A duct is provided with a concave portion so as to protrude from outside the duct toward the inside thereof. The airflow rate sensor is disposed in the duct so as to cover the concave portion, in which the through hole is in communication with the space in the concave portion. The concave portion has a bottom provided with an opening. Accordingly, an installation structure of a sensor for reliably sensing a flow rate and a projector apparatus having the same are provided.

摘要： An image display device of the present invention includes two lamps A and B as light sources. A mirror is pivotally moved to supply light from the lamp A, B to an optical system. In the case where the lamp A is used, the mirror is temporarily driven in the direction of lamp B before the lamp A is activated. Thereafter, the mirror is returned to the position where the lamp A is used, and is pressed against a restraining member. Thereby, the mirror is positioned at a proper angle with respect to the light from the lamp A when the lamp A is activated.

摘要： A projector comprises: a cooling fan for sucking ambient air through a filter; switching means for switching the operational mode of the cooling fan between a lowland mode and a highland mode; and control means adapted to obtain current fan voltage to determine the normal rpm value for that current fan voltage in reference to a highland voltage-rpm characteristic when the switching means is in the highland mode, obtain current fan rpm, and enables alarming means to issue a filter clogging alarm in the event that the current fan rpm is larger than the normal rpm value plus a predetermined value. Thus, filter clogging can be detected with precision in highlands.

摘要： A circuit board is attached in a displaceable manner to a lamp holder. When the lamp holder is attached to a holder housing, ends of pins extending from the holder housing are inserted into holes of the circuit board. At the time, the circuit board is guided and corrected for a positional shift by inclines at ends of the pins. Accordingly, a connector on an under surface of the circuit board is opposed to a connector on a circuit board in the holder housing side, whereby the two connectors can be properly connected.

摘要： A mounting structure for a temperature sensor, which detects the temperature of a wall surface. The mounting structure includes a groove formed in the wall surface and having an inlet from which the temperature sensor is inserted. The temperature sensor includes a main body, which has a temperature detection surface that detects the temperature of the wall surface, and a lead wire connected to the main body. A support supports the main body. A wire bender bends the lead wire of the temperature sensor extending out of the inlet to press the temperature detection surface of the temperature sensor against the wall surface with an elastic force of the lead wire that is produced when the lead wire is bent. A stopper restricts movement of the main body of the temperature sensor.

摘要： A projection display device includes: a projection portion which enlarges and projects the light modulated by a imager portion; a control circuit; and a main body cabinet. The projection portion is formed by a projection lens portion into which the light from the imager portion is entered and a mirror portion which reflects the light having passed through the projection lens portion and lets the light travel toward a projection plane. The mirror portion is disposed so as to be shifted from an optical axis of the projection lens portion in a direction opposite to a direction in which the incident light from the projection lens portion is turned back. The control circuit portion is disposed in a space which is produced between the projection lens portion and the main body cabinet by a position gap between the projection lens portion and the mirror portion.

摘要： A lamp unit configuring a light source device capable of efficiently cooling a light source by a simple structure includes a light source and a plurality of air outlets for discharging the cooling air for cooling the light source. The plurality of air outlets include a first air outlet for discharging the cooling air in a first direction and a second air outlet for discharging the cooling air in a second direction. The cooling air discharged through the first air outlet is different in airflow rate from the cooling air discharged through the second air outlet, and the first direction is different from the second direction when viewed in the direction of the optical axis of the light source.

摘要： A projection display device is provided with an adjustable leg which adjusts an inclination of the main body cabinet. The adjustable leg includes a leg portion whose projection amount from the bottom surface is changed, and a foot portion which is contacted with an installation plane of the projection display device, the adjustable leg being expandable and contractible from a reference length position at which the main body cabinet is placed in parallel to the installation plane. The bottom surface of the main body cabinet has a recess portion which is configured so as to guide in and out of the foot portion, as the adjustable leg is contracted and expanded. The foot portion has an index portion which is set to the same height as the height of the bottom surface with respect to the installation plane, when the adjustable leg is positioned at the reference length position.
