Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a so-called camera-integrated VTR.

[Summary of the idea]

A camera-integrated VTR is separated into a main body and a grip body that can be attached to and detached from each other, and various operating modes within the main body can be optically displayed on an optical mode display section provided on the attachment/detachment surface. A light guiding portion is provided on the attachment/detachment surface of the grip body, so that the optical display of the optical mode display portion is displayed within an optical view indexer within the grip.

[Conventional technology]

Conventional camera-integrated VTRs have a camera section, a VTR
Since the camera section and the viewfinder section are substantially integrated with each other, the operating modes of the camera section and the VTR section can be optically displayed using an optical viewfinder or an electronic viewfinder, and this method is also easy.

[Problem that the invention attempts to solve]

When considering a camera-integrated VTR that is compact and convenient to carry, the camera and VTR sections are integrated into a main body, while a grip body incorporating an optical viewfinder and a battery is formed, and the two are combined when in use. It is conceivable that the image be captured by moving the camera. This is because it is convenient to carry when not photographing.

However, if the optical viewfinder is separated from the main body in this way, the camera section and VTR
A problem arises in that the operating mode display of the unit cannot be optically displayed within the optical viewfinder.

Of course, it is possible to display the information by forming a number of contact points between the main body and the grip body so that they come in contact with each other when the two are connected, and by arranging a light emitting element such as an LED within the optical viewfinder. In this case, there is a problem that contact failures are more likely to occur, resulting in poor reliability.

[Means for solving problems]

An optical mode display section 31 is provided on the grip body coupling surface 3f of the main body 1, and the main body coupling surface 4 of the grip body 2 is provided with an optical mode display section 31.
A light guiding section 34 is provided in the optical display section e, so that the display on the optical mode display section 31 of the main body 1 is displayed within the optical viewfinder 12.

[Effect]

The mode display displayed on the optical mode display section 31 of the main body 1 is displayed as is in the viewfinder 12 within the grip body 2.

〔Example〕

Regarding the drawings below, the camera integrated type according to this invention
Explain about VTR.

The camera-integrated VTR according to the present invention is composed of a main body 1 and a grip body 2, both of which are
and 2, their casings 3 and 4 are made of synthetic resin. The main body case 3 is formed into a substantially rectangular parallelepiped shape, and the grip case 4 is also formed into a substantially rectangular parallelepiped shape.
The lens is curved to fit the palm of the photographer's right hand.

A camera section 5 and a VTR section 6 are respectively housed in the main body case 3, and are located opposite to a square window hole 8 formed at the upper part of the front surface 3a of the main body case 3. A window frame 47 is fixed in a retracted position, and the objective lens 7 of the camera section 5 is exposed to the outside through a window frame 47a formed on the window frame 47. A dustproof cover 9 is attached to the rear side of the front surface 3a so as to be vertically slidable between it and the window frame plate 47, and its upper edge is attached to the window hole 8 of the front surface 3a. The knob 1 of the cover 9 is slightly protruded outward.
It is set to 0. The cover 9 can be clicked into two positions: a downwardly slid state, that is, an open state, as shown in FIG. 1, and an upwardly slid state, that is, a closed state, as shown in FIG. be done.

The cover body 11 is aligned so that it has the same outline as the main body case 3 from the top surface 3c of the main body case 3 to the left side surface 3e.
is attached, which is rotatable with respect to the main body case 3 using its lower edge as a hinge, and when the lid 11 is opened, the cassette mounting part (not shown) of the VTR unit 6 is attached. ) so that a tape cassette (not shown) can be detachably attached to the tape cassette (not shown).

On the other hand, in the case of the grip body 2, an optical view indexer 1 is provided in the upper part of the grip housing 4.
2 is included. Reference numeral 13 denotes the objective lens, which is located at the upper part of the front surface 4a of the grip housing 4.
It is exposed to the outside through a window hole 14 formed therein. A so-called eye cup 15 made of an elastic material is attached to the upper end of the rear surface 4b of the grip housing 4, and an eyepiece (not shown) is attached to this. An optical system is formed, and an optical view indexer 12 is configured. Note that this optical view finder 12 is completely independent of the optical system including the objective lens 7 of the camera section 5 described above.

A battery 16 is removably housed within the grip housing 4. Reference numeral 17 denotes an inlet/outlet for the battery 16, which is formed on the front surface 4a of the grip casing 4. In addition, when the battery is removed, the lid 18 is closed so as to close the entrance 17.
(See Figure 2), and when storing the battery, the tip of the battery is used to push open the lid 18, push it down inside, and remove the battery, which automatically raises the lid 18. It is configured to rise to close the entrance/exit 17. In addition, in FIG. 2, the lid body 18 is shown in a state halfway through its ups and downs. The grip housing 4 also has a right side surface 4f.
A band 19 is attached to face the grip case 4, and the photographer inserts his right hand between the band 19 and the grip case 4 to grasp the grip case 4.

The right side surface 3f of the main body casing 3 and the left side 4e of the grip casing 4 are joint surfaces that face each other, and a joining means is formed on each of these surfaces. To explain this using FIGS. 4 and 5, there are multiple L-shaped hooks 20 (four locations in the figure) on the right side surface 3f of the main body case 3, each facing forward. On the other hand, a recess 21 is formed on the left side surface 4e of the grip case 4, facing each of the above-mentioned hooks 20. Engagement recesses 22 are respectively formed.

Therefore, when fitting each hook 20 of the main body case 3 into each recess 21 of the grip case 4, the right side surface 3f of the main body case 3 and the left side surface 4e of the grip case 4 are inserted.
are in close contact with each other, and in this state, by relatively shifting the main body case 3 forward, the tip of each hook 20 is inserted into the engagement recess 22 in the respective recess 21, and both 3 and 4 are combined. do. That is, the main body 1 and the grip body 2 are combined.

In order to lock in this combined state, a locking means described below is provided. That is, as shown in FIGS. 3 and 5, a lever 23 is attached to the rear surface 4b of the grip housing 4, and is slidable in the left-right direction.As shown in FIG.
4, the tip of the locking piece 25 connected to the lever 23 is always slid and biased toward the main body case 3 side, and the tip of the locking piece 25 is connected to the recess 21.
With this locking piece 25, the hook 2 is protruded inward.
0 from moving (sliding) within the recess 21.

Therefore, when the hook 20 enters the recess 21 when the main body casing 3 and the grip casing 4 are combined, the locking piece 25 retreats against the spring 24, and further moves as shown in FIG. Once this hook 20 enters into the engaging recess 22, the locking piece 25 protrudes into the recess 21 and locks the hook 20. Such a locking means 26 is provided in any one of the recesses 2.
It is sufficient if it is provided within 1.

In the state shown in FIG.
In the state where the main body case 3 is slid in the opposite direction against this, the main body case 3 is relatively shifted rearward, thereby allowing the two bodies 3 and 4 to be separated from each other.

A plurality of electrical contacts 27 made of a metal plate are formed on the above-mentioned connecting side surface 3f of the main body case 3, that is, the right side surface 3f, while the left side surface 4 of the grip case 4 is formed with a plurality of electrical contacts 27 made of a metal plate.
A plurality of electrical contacts 28 made of conductive pins are attached to the contact point 27 so as to face each contact point 27, and when both 3 and 4 are combined as described above, the contacts 27 and 28 are electrically connected to each other. touch each other,
A power supply current is supplied from a battery 16 in the grip case 4 to the camera section 5 and the VTR section 6 in the main body case 3, respectively. Further, the rear surface 4b of the grip housing 4 has a push button 30 for a trigger switch, and the signal from this button is also connected to the contact point 2 mentioned above.
A signal is supplied into the main body 1 through either 7 or 28. In fact, the push button 30 enters the standby state at the first push, and the tape runs and recording occurs at the second push.

On the right side 3f (joint side) of the main body 3
As is clear from the figure, an optical mode display section 31 consisting of a plurality of (four in this example) light emitting elements is provided, while the left side surface 4e of the grip housing 4
As is clear from FIG. 5, a light guide section 34 is formed on the (joint side surface) at a position opposite to the optical mode display section 31 of the main body case 3 described above.

That is, a plurality of window holes 32 (four in this example) are provided facing each light emitting element of the optical mode display section 31, and a rectangular mask 33 is further provided at the focal point within the optical system of the optical viewfinder 12. (see Fig. 3), and the four corners of this mask 33,
A light pipe 35 (optical fiber) made of plastic or glass is provided between each window hole 32 described above. That is, one end of the light pipe 35 is just fitted into the window hole 32 so that its end face directly faces the optical mode display section 31 of the main body casing 3, and the other end is inserted into the window formed at the four corners of the mask 33. It is fitted directly into the hole. FIG. 7 shows an example of an image seen when looking through the viewfinder 12, in which the end face of each light pipe 35 is positioned outside the field of view frame 36 of the mask 33.

Therefore, when the light emitting elements such as LEDs constituting the optical mode display section 31 of the main body 1 light up in accordance with the respective mode states of the camera section 5 and the VTR section 6 within the main body 1, this lighting occurs within the optical viewfinder 12. are displayed respectively.

Next, an example of mode display will be described, and for convenience of explanation, the symbols a to d are particularly shown in FIG. 7.

First, a is turned on when the color temperature is low, such as when taking an image indoors. In this case, the color filters in the optical system of the camera section 5 in the main body 1 may be switched. Reference numeral 37 shown in FIG. 2 indicates this switching lever, which slides up and down. b indicates the standby state. In other words, the above-mentioned push button 3
If you press 0 once, this b will light up. When this push button 30 is pressed again, b goes out and c lights up to indicate that an image is being taken (recorded). d indicates an insufficient light amount state. In this case, lighting is sufficient. It should be noted that the means for displaying the above-mentioned modes of the camera section 5 and VTR section 6 in the main body 1 by each light emitting element in the optical mode display section 31 is well known, so a detailed explanation thereof will be omitted. Further, as these light emitting elements, those having different colors can also be used.

The camera section 5 in the main body 1 can be switched to three positions: telephoto, standard, and wide-angle by moving an objective lens 7 forward and backward. As shown in FIG. 8, the movement of the lens 7 is controlled by a fixed tube that accommodates the lens barrel 38 in a threaded groove 39 formed on the outer peripheral surface of the lens barrel 38 of the lens 7 and guides it back and forth. A projection (none of which is shown) protruding from the inner surface of the main body casing 3 is engaged with the projection, and as shown in FIG. As shown in FIG. 8, a part of the connecting plate 41 attached to the rear surface of the switching lever 40 is extended to the front of the lens barrel 38, and a notch 43 formed in the extension part 42 is connected to the connecting plate 41. A protrusion 44 protruding from the front surface of the lens barrel 38 is engaged, and the lens barrel 38 is moved forward and backward by the upper, middle, and lower sliding of the switching lever 40, and the optical system of the camera unit 5 is moved to a so-called wide-angle, Standard and telephoto state.

A link 45 is provided below the lens barrel 38, and this link 45 is connected via a shaft 46 to a window frame 47 fitted to the rear of the window hole 8 of the main body case 3 (this window frame 47 is the first (as shown in the figure) so that it can seesaw freely. and this link 4
5 is bent, and this bent portion 45c is loosely engaged with the through hole 42a of the extension portion 42 of the connecting plate 41, and when the switching lever 40 is in the neutral (standard) position, the link 45 is As shown by the solid line in FIG. 8, it is in a substantially horizontal state.

On the other hand, as shown in FIG.
8b is formed, and when the dustproof cover 9 is slid upward to shield the front of the lens 7 as shown in FIG.
b are arranged to be in contact with or to be opposite to the left and right lower ends 45a and 45b of the link 45, respectively, with a slight interval therebetween.

Therefore, when the switching lever 40 is now slid upward from the standard (neutral) position, the wide angle state is established, and the link 45 is inclined as shown by the dashed line. Therefore, when the cover 9 is closed in this state, the abutting portion 48
a collides with the lower end 45a of the link 45 and rotates it to a substantially horizontal position as shown by the solid line. As a result, the connecting plate 41, that is, the switching lever 40 returns to the neutral position, and the lens 7 also returns to the standard position.

Further, when the switching lever 40 is slid downward to change the open state of the cover 9, the link 45 tilts in the opposite direction to the above-mentioned direction, resulting in a telephoto state. Cover 9 in this state
When closing, the abutting portion 48b abuts the lower end 45b of the link 45, returning the link 45 to a substantially horizontal state. That is, the switching lever 40 returns to the neutral position. In this case, the connecting plate 41
It is also possible to push up the lower end edge of the extension part 42.

In this way, the optical system of the camera unit 5 can be set to the standard state by closing the cover 9 when it is not in use, and therefore images will be taken in the standard state unless the switching lever 40 is operated during subsequent imaging. It turns out.

As shown in FIG. 8, a cover open detection switch 50 is installed in the main body casing 3 below the dustproof cover 9, and the switch 50 is turned on, for example, when the cover 9 is open. ing.

This switch 50 is connected in series with other switches 51a, 51b, 51c, . . . as shown in FIG. These switches 51a,
51b... is, for example, a detection switch for preventing erroneous tape erasure, a switch operated by the push button 30 described above, or the like. The DC power supply terminal 52 is connected to the resistor 53 and the above-mentioned switches 50, 51.
A, 51b . This computer 54 controls various operations of the camera section 5 and VTR section 6.
If a DC potential (voltage) is applied to the control terminal 55, it will not operate.

Therefore, when all the switches are turned on, that is, when all the recording conditions are satisfied, the control terminal 55 of the computer 54 becomes the ground potential, and the computer 54
becomes operational.

[Effect of idea]

According to the present invention described above, although the main body 1 and the grip body 2 are separated and independent, in the viewfinder 12 in the grip body 2,
It has the feature of being able to monitor each mode on the main body 1 side. And generally view index 12
It is conceivable to arrange a plurality of light emitting elements inside the main body 1 and connect them to the electronic circuit inside the main body 1 via a plurality of electrical contacts, but in the case of such a configuration, there is a risk that the entire viewfinder 12 becomes large. Furthermore, since electrical contacts are used, there is a risk that reliability may be poor.

However, according to the present invention, the above-mentioned problems can be easily avoided, the configuration for attaching and detaching the main body 1 and the grip body 2 can be simplified, and the electrical wiring can be completed by running the length inside the main body 1. Has characteristics.
