摘要： PROBLEM TO BE SOLVED: To provide a video camera constituted so that a photographer can firmly hold a camera main body with the left hand, without inadvertently catching his or her finger on the front surface of a lens. SOLUTION: An electronic display 3 is arranged inside the camera main body 2, so as to be visually recognized from the back of the camera. A photographic lens part 4 is arranged not so as to physically interfere with the electronic display 3. A lens barrier shields the photographic lens, when the camera is not used and is housed without projecting from the camera main body 2. At the time of taking a photograph, the lens barrier 8 is operated in the direction of an arrow, so that the lens barrier 8 pivotally supported by the camera main body 2 is turned by a rotary shaft. At this time, a power supply switch not shown in the figure, which is linked with a detecting member, is turned on, to obtain a photographing ready state.

摘要： PURPOSE:To provide the video camera in which a recording state is confirmed through the reproduction of a picked-up image to be recorded by the use of a finder section even when the eye is detached from an eyepiece hood. CONSTITUTION:The video camera is a camera in which a recorded picked-up image is reproduced on a finder section to confirm the recording state. The finder section is provided integrally with a camera body 1 and a moving member 6 of the finder section moves relatively a position of a display screen of a CRT 2 with respect to an eyepiece lens 3 to a 1st position nearly equal to a focal point of the eyepiece lens 3 and a 2nd position at the inside of the focal position of the eyepiece lens 3 and closer to a display screen of the CRT 2 in excess of a range of adjustment of diopter of the eyepiece lens 3, and when the position of the display screen of the CRT 2 with respect to the eyepiece lens 3 is at the 1st position, the eye is made to abut on the eyepiece hood 7 to confirm visually the picked-up picture on the display screen and when the display screen is at the 2nd position, the eye is parted from the eyepiece hood 7 to visually confirm the picked-up image on the display screen.

摘要： PURPOSE:To obtain a video camera whose portability is satisfactory, by forming an optical finder with a single-lens reflex type finder, and also rotating a part of a finder bodytube and folding it to the side of a camera body when the finder of the video camera is not used. CONSTITUTION:When using a video camera, a finder bodytube 4A is protruded to the side of a camera body 1, and in this state, a user puts the camera body 1 on hit right shoulder, and uses the camera by peeping into an eyepiece part 5 with his right eye. On the other hand, when the camera is not used, the finder eyepiece part 5 is rotated to a storage hollowed part 1A provided on the side of the camera body 1, so that the bodytube part 4 is stored.

摘要： PURPOSE:To obtain a device which enables light release operation, has low power consumption, and is applicable to a simultaneous sound recording cinecamera, etc., by providing a ratchet disk rotating, pitch by pitch, by powering up an electromagnetic device, and a cam disk and displacement members. CONSTITUTION:A ratchet disk 11 capable of rotating, pitch by pitch, in one direction by powering up an electromagnetic device 14 in a short time, a cam disk 10 coupling with it, and displacement members 12, 7, 5, etc., displaced in contact with the cam part of the cam disk 10 are provided to bring a pinch roller 3 and a capstan shaft 1 into press contact with each other or to separate them from each other according to the displacement of those displacement members. For example, when the electromagnetic device 14 is powered up, a movable iron piece 15 is attracted downward and a ratchet pawk 13 drives the ratchet disk 11 to rotate the control cam disk 10 by an angle equivalent to one tooth of the ratchet disk 11. This turning permits the contact part of a pin 12 to move from a cam A to a B, and the pinch roller 3 is brought into press contact with the capstan 1 through the rotation of a control plate 7 and an arm 5.

摘要： PURPOSE:To make this camera usable for both of films for simultaneous sound- recording and exclusive for image recording by automatically changing over the film feed speed for taking to constant-speed controlling and variable-speed controlling. CONSTITUTION:When a film cartridge 1 for simultaneous sound-recording is loaded in the camera and the camera is set in a sound-recording state, a switch 52 is closed and a loop detecting member 24 contacts the loop part of a film 2. When a main switch 46 and a release switch 47 are closed in this state, film-feed motors 40, 7 for sound-recording and taking operate respectively. When the detecting member 24 detects a decrease or increase in the loop of the film 2, it turns OFF or ON a switch 51 which in turn controls the rotating speed of the motor 7, thus the film loop is maintained always at a predetermined amount. When a cartridge exclusive for image recording is going to be used, a switch 52 is open; hence, the motor 7 is subjected to constant-speed controlling by a governor 49. In this way, either of the cartridges may be used.

摘要： PURPOSE:To set an optional directivity of a directional microphone regardless of the zooming, by not only providing a switch means to cut off the coupling among the zooming action, the directivity and a directivity varying means but also providing a manual setting means. CONSTITUTION:This camera incorporates a means that varies the directivity of a directional microphone in coupling to the zooming action of a zoom lens. A switch means 14 is provided to cut off the coupling between the zooming action and a directivity varying means of the directional microphone when necessary. Furthermore a manual setting means 15 is added to set the directivity of the directional microphone regardless of the zooming action of the zoom lens. Thus the coupling between the zooming action and the directivity varying means is cut off at the position slided to the upper left side in the diagram. At the same time, the directivity of the directional microphone can be freely set regardless of the zooming action.

摘要： PURPOSE:To provide such a cartridge erroneous charge preventing mechanism in response to the manual mode change-over as makes it possible to charge one cartridge and makes it impossible to charge the other cartridge in accordance with the selected condition of the silent and sound operating modes. CONSTITUTION:If a manual mode changing member 10 is set in a position SO so as to effect the sound photography, a control member 27 is shifted to its upper position, as shown in solid lines, so that a control member 27a is shifted to a position above a cartridge erroneous charge preventing member 25c, so that a step portion 27d is shifted to a position below an arm portion 25d, and so that a pin 28 is shifted to a position above the arm portion 25d. If, under this condition, a charge chamber 2 is charged with acartridge C1, preventing claws 25a and 25b are retracted from the charge chamber 2 so that the charge is allowed. If, however, a silent cartridge C2 is to be charged, the preventing claw 25a is blocked from retracting from the charge chamber 2 so that the charging operation of the cartridge C2 is made impossible.
