Abstract: PURPOSE:To extend the recording time of sound for one picture image as occasion demands by repeating the next sound recording operating at every accumulation of a sound signal of one track until the operation of sound collection is terminated. CONSTITUTION:After the time elapse corresponding to the storing capacity of a sound memory 19 since the start of a sound collection operation, the sound collection is temporarily terminated and the memory 19 is readout and a data readout is stored at a disk 16 by a head 23. After that, the sound collection is restarted and after a prescribed time elapse, a picture signal from the memory 19 is recorded at an unuse track on the disk 16. Such an operation is repeated until the sound collection is terminated.

Abstract: PROBLEM TO BE SOLVED: To easily confirm erroneous attaching at the time of attaching a driving part driving a movable lens in an optical axis direction at the attaching part of a lens barrel. SOLUTION: This lens driving mechanism is provided with guide shafts 11 and 12 disposed in parallel with the optical axis of a photographing lens system, the movable lens 2 held by a lens moving frame 1, a nearly cylindrical sleeve part 3 provided at the lens moving frame and slidingly supported by the guide shaft, and the driving part 13 moving the movable lens in the optical axis direction with the lens moving frame. In this case, interference bodies 9 and 10 positioned at both sides of an engaging piece 8 in the optical axis direction separating from the engaging piece 8 are protrusively provided at the inside of the recessed part 5 of the sleeve part 3, and a pair of interference projecting parts 23 projecting so as to be opposed to the interference bodies from an engaging protrusion 21 is provided at the nut body 18 of the driving part 13, and in the case that the engaging protrusion 2 is not held by the engaging piece 8 when the engaging protrusion 21 is engaged with the engaging piece 8 by inserting the engaging protrusion 21 to the inside of the recessed part of the sleeve part 3, the engaging protrusion 21 is prevented from being inserted to a specified position at the inside of the recessed part 5 by making the interference projecting part 23 butt the interference body.

Abstract: PURPOSE: To obtain an ideal collapsibly mounted state and to make a lens barrel compact by forming an opened notch at a position corresponding to the projection part of a fixed lens barrel on a movable lens barrel and positioning the projection part of the fixed lens barrel in the notch of the movable lens barrel. CONSTITUTION: This is the collapsible mount type lens barrel 1 constituted so that the movable lens barrel 7 is disposed so that it can be extended in an optical axis direction with respect to the fixed lens barrel 29 and a photographing action can be executed in a state where the lens barrel 7 is extended. When the lens barrel 7 is collapsibly mounted, the lens barrel 29 is covered with it. Besides, the rectangular notch 7c opened backward is formed at the right inclined upper part of the rear edge of the lens barrel 7 so as to prevent the driving motor of an iris mechanism from interfering with the lens barrel 7 when the lens barrel 7 is restored with respect to the lens barrel 29. Therefore, since the projection part 28 of the lens barrel 29 does not collide with the rear edge of the lens barrel 7 and it is positioned in the notch 7c when the lens barrel 7 is collapsibly mounted, it is enough to consider the problem of the interference of only optical parts. As the result, the ideal collapsibly mounted state is obtained.

Abstract: PURPOSE: To reduce the number of parts, to make a lens barrel compact, to reduce assembly man-hour and to reduce a cost by using the yoke and the like of a linear motor being the respective driving means of plural movable members as the common parts. CONSTITUTION: A movable lens barrel 7 is supported so as to be freely moved with respect to a fixed lens barrel. In a state where the lends barrel 7 is extended from the fixed barrel, the photographing action can be executed. In a state where it is restored in the fixed barrel, the photographing action cannot be executed. When the moving coil 18 of a lens holder 15 and the moving coil 10 of the lens barrel 7 are respectively positioned to be fitted out a guide shaft 36, a magnetic path extending over magnets 38 and 38 - the yoke 34 (a blocking plate 37) - the guide shaft 36 - the magnets 38 and 38 is formed so as to constitute the linear motor for a movable lens barrel 11 and the linear motor for a zoom lens 19. By using the yoke 34, the magnets 38 and the like of the motors 11 and 19 as the common parts, the number of parts is reduced and the lens barrel is made compact.

Abstract: PURPOSE:To improve horizontal resolution without changing an F-number value in the small diaphragm of an iris. CONSTITUTION:In this diaphragm for a camera 10 on which an opening part 12a is formed on a diaphragm plate 12 placed in a lens optical system C for the camera, the opening part 12a is freely opened/closed by a diaphragm blade reciprocating along the diaphragm plate 12, and an ND filter 20 is fixed so as to be projected to a diaphragm part opening/closing the opening part 12a of the diaphragm plate 12 of the diaphragm blade, a pair of the left and right diaphragm blades 13 and 14 are freely horizontally slide-moved along the diaphragm plate 12. On the other hand, the opening shape of the projecting part 21 of the ND filter 20 is imitated to the opening shape of the diaphragm part 13a of the diaphragm blade 12 of the left side as much as possible, to project the projecting part 21 by prescribed length compared with the diaphragm part 13a of the diaphragm blade 13.

Abstract: PURPOSE:To record a video signal and an audio signal with a simple operation by leaving a video track indicated by an audio track as a reserved track of no signal, and performing a video recording and an audio recording separately. CONSTITUTION:The output of a microphone 4 is given to and compressed at a time compression memory 24. A compressed audio signal is recorded on a magnetic sheet disk 18 with a head 17b. Next, when a track reserve switch SW-A is depressed with a prescribed timing, the video track, the address of which is designated, is formed as a vacant track of no signal. When a still video signal is inserted and picture-recorded on the reserved track, first of all, the audio signal recorded previously is reproduced while it is extended. At such a time, when a switch SW-C is depressed, the heads 17a and 17b are situated in a waiting state at a reserved track position. When a switch SW1 is depressed in such a state, a bit of video information from a TV camera 1 is recorded on the reserved track.

Abstract: PURPOSE:To prevent a malfunction by using a shutter button capable of being operated in three steps in a fixed sequence, carrying out a photographing preparation such as a photometry, a range finding in an operation in the first step and carrying the start of a recording or the photographing in the second and the third steps. CONSTITUTION:By operating one shutter button, a photographing preparation, recording start and the photographing can be carried out. The operation of the respective actions cannot be done without following a fixed sequence. For instance, when the shutter button 5 is pressed, initially, the first switching element 27 is turned on and when strengthening the pressing power, the second switching element 35 is turned on. Further when strengthening the pressing power, the third switching element 36 is turned on. Since the sequence in which the switching elements are turned on and off is constantly fixed, there is no feae for making a malfunction and a series of operation for recording is carried out by a prescribed sequence.
