Title: Light irradiating unit
Inventor: IMAMURA KENJI
IPC: F21V29/505
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To cool a lamp, and prevent scattering of broken pieces when the lamp is broken, by forming a notch part by cutting off an opening part end part of a concave reflecting mirror in plural places, covering a front opening of the concave reflecting mirror to surround a discharge lamp or a front opening of a lighting fixture with a front face plate composed a light transmissive material, and covering the notch part and a ventilating window of the lighting fixture with a ventilating plate. SOLUTION: A front glass installing member 41 on which a glass plate 4 is installed is fixed to a front opening of a concave reflecting mirror 2, and a mesh member 5 as a ventilating plate through which broken pieces of a discharge lamp 1 cannot pass is installed in the front glass installing member 41, and covers a notch part 22 of the concave reflecting mirror 2. A cooling wind enters the concave reflecting mirror 2 from an air vent of a base sleeve 13, and flows out of the notch part 22 by cooling the discharge lamp 1. Since this unit is formed in such a structure, even if the discharge lamp 1 bursts, the broken pieces of the discharge lamp 1 do not scatter outside from the concave reflecting mirror 2, and damage of the inside of a projector, a wiring cord and a combustible member can be prevented.

Title: Cassette loading device
Inventor: TOYOGUCHI TSUTOMU
IPC: G11B15/665
Filed: 1989-02-10
Abstract: PURPOSE:To simplify and miniaturize device constitution by actuating a cassette transfer mechanism in accordance with the detection of the insertion operation of a cassette by cassette insertion detecting arms which are operated to turn when the cassette is loaded and a cam plate engaging therewith. CONSTITUTION:Detecting pins 40, 42 pendant from the cassette insertion detecting arms 38, 39 are pressed when the tape cassette is inserted to a cassette holder via the cassette insertion port. The detecting arms 38, 39 are thereby turned by overcoming the energizing force in arrow directions I, J. The cam plate 45 is turned in an arrow L direction by this turning operation, by which the contact engagement of a stopper cam surface 45a and a stopper pin 47 is released. As a result, the movement of a cassette loading control frame 3 in an arrow direction G is enabled. Since the detecting arms 38, 39 are operated to be turned by the cam plate 45 when the cassette loading control frame 3 is operated to be moved by a driving means, the cassette is prevented from being pressed to the cassette insertion port side.

Title: Controller and control method for remote supervisory camera
Inventor: KANEKO KAZUMASA
IPC: H04N5/232
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide the controller and control method that surely and easily control a camera in a desired attitude even while observing a video image of a remote supervisory camera having a transmission delay. SOLUTION: A center side main control section 4 sequentially stores an attitude change of a universal head 2 to a locus recording section 12. Furthermore, the control section 4 gives a moving command to a camera/universal head drive control section 3 by using an attitude of the universal head 2 as an object position at a point of time dated back by a delay time of a video image till the universal head 2 is completely stopped after the command stop is issued by the operator. Then a video segmentation section 11 segments a video image at the moment of command stop issuance as a still image, and a video changeover section 10 replaces the video image of an image display section 7 with its still image.  When the universal head 2 reaches an object position and the delay time of the video image elapses, then the video image of the actual object position is sent to the center, the video image of the video display section 7 being replaced with the video image by a supervisory camera 1 again.
