In a lens mounting mechanism, by rotating a ring member through touching lugs of the ring member and aligning grooves of a base member and recesses of the ring member in the circumferential direction, and then inserting a lens barrel into a hole portion, the lens barrel is moved to the hole portion without being interfered by projections of a barrel mounting member, so that the lens barrel can be inserted into the hole portion until a flange portion abuts against an opening end surface. Then, by touching the lugs of the ring member and rotating the ring member to displace the recesses from the grooves of the base member in the circumference direction, the projection of the barrel mounting member is locked by the ring member and the barrel mounting member is fixed to the base member, so that the lens barrel can be mounted to the apparatus body.

Provided is an electric linear actuator advantageous in downsizing and weight reduction. The electric linear actuator includes: a housing; a motor held by the housing; a nut member rotatably held with respect to the housing; a screw shaft threadedly engaged with the nut member; a drive shaft directly coupled with the motor; a rotation transmitting member rotatably supported about the drive shaft; a rotary driven member fixed to the nut member and rotated in accordance with the rotation transmitting member; a clutch member to which rotation of the drive shaft is transmitted, and which is provided so as to freely advance and retract in an axial direction of the drive shaft, and in which meshing with the rotation transmitting member is effected at an engagement position, and meshing with the rotation transmitting member is cancelled at a retraction position; and a setting lever capable of setting the clutch member to one of the advance position and the retraction position.
摘要:
The object of the present invention is to further improve a lens barrel moving mechanism of a liquid crystal projector and to provide a lens moving mechanism which has simple structure and is capable of achieving the smooth and high precision movement of a lens barrel, and a liquid crystal projector employing the lens moving mechanism. The present invention provides a lens moving mechanism for moving a lens retaining member 20, which retains a lens barrel 15 provided therein with a projection lens for projecting light with image information, in the directions of Z axis and X axis. The lens moving mechanism comprises first and second guiding mechanisms 23, 23, 24, 24 including a track member, a movable member, and a plurality of rolling members arranged between a rolling member running surface of the track member and a rolling member running surface of the movable member, whereby the lens barrel 15 is guided by the first and the second guiding mechanisms 23, 23, 24, 24 in the directions of Z axis and X axis.

A television set carries out communications with a remote control. When the television set displays a picture based on a picture signal subjected to quality adjustment, a signal level of a quality adjustment parameter is obtained, and the data indicating the obtained signal level is transmitted to the remote control. The remote control displays the received data. The user checks the displayed data, and enters data for changing the signal level so that the remote control transmits the entered data to the television set. The television set receives the changed level data, and adjusts the quality relating to the picture signal based on the received level data. The television set displays the picture of the quality adjusted according to the signal level changed by the user.

Even when a user is by the immediate side of a screen of a large screen television receiver such as a plasma TV receiver, the user can view an image displayed on the screen entirely by contracting the image to be displayed, and power consumption of the television receiver can be reduced. When the user choose a contraction mode for displaying the image with contraction, the video signal processor performs pixel skipping of video data corresponding to predetermined pixels to video data of a television signal received by a tuner. The display panel displays a contracted image with an initial contraction ratio at an initial display position on a screen of the display panel with using the processed video data. The contraction ratio and the display position of the contracted image on the screen of the display panel can be varied optionally by operating a wireless remote controller, corresponding to a distance between the user and the screen of the display panel or according to the user's predilection.

摘要:
On a display unit, icons representing types of video signals supplied to respective ones of a plurality of input terminals are displayed. When a user operates a remote and selects an icon representing the type of desired video signal, a video image derived from the video signal of the desired type supplied to the input terminal that corresponds to the selected icon is displayed on the display unit. In such a situation, arrangement of icons on the display unit can be changed by a user instruction given by an operation of the remote. Further, the icons also show shapes of the input terminals, and therefore, the user can easily confirm to which input terminal of which shape the device supplying the video signal of the type indicated by the icon is to be connected.
