Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a video camera used for continuously recording video and audio.

Some of the cameras have a recording device such as a video tape recorder integrally incorporated therein, and others have a detachable structure. Both of them are suitable for the present invention.

[Prior Art] Recording by a video camera is started by pressing a recording start button after switching a normal mode switch to a recording mode.

By the way, once the video camera is switched to the recording mode, various functions necessary for recording, such as the viewfinder circuit and the drive motor circuit for autofocus, are activated, and when a photo opportunity occurs, it is immediately It is in a standby state so that it can respond.

However, the shutter chances do not come often,
Even if you do not press the recording start button so much, the various circuits above are activated just by setting the recording mode, so there is a disadvantage that there is power consumption and the battery runs out quickly. In order to avoid the drawbacks, a switch with a so-called power save switch has been developed that controls the power save function that cuts off only the circuit that can be started up instantly even when the recording mode is ON. .

That is, for example, as shown schematically in FIGS. 6 and 7, only the power switch on / off slide switch (2) is provided on the side of the recording start / stop button (1).
A slide cover (3) is integrally linked to the operator (2a) of the slide switch (2). In this case, the power save switch (2) is set so that the recording can be started anytime. To the right of Fig. 7 (solid line)
If you switch to the OFF position, power saving does not work, so power consumption is a little high, but the recording button (1) is always available
Can be operated. On the other hand, if you switch the power save switch (2) to the ON position on the left side (chain line) in Fig. 7, instead of activating the power save function, the power save is working, so press the recording start button (1). However, since the normal recording is not performed, the slide cover (3) covers the upper part of the recording button (1) so that the recording button (1) cannot be operated.

[Problems to be Solved by the Invention] In the switch device of the type shown in FIGS. 6 and 7 above, when the power save function is ON, the recording button (1) automatically becomes inoperable or difficult, and the recording is erroneously performed. It is a convenient one that can prevent troubles such as pushing a button and recording with a bad image, and also a slide cover (3)
Since the power save state can be turned on and off by simply moving the recording button (1) closer to and away from the recording button (1), there is an advantage that the user can operate it with one hand and with one finger such as thumb. However, it also has the following drawbacks.

That is, since the slide cover (3) is relatively bulky as shown in the figure, even at the position shown by the solid line in FIG. There was a problem that the recording button (1) could not be operated smoothly by touching 3).

Further, if the slide stroke of the slide cover (3) is lengthened, the above-mentioned trouble is solved for the time being, but the trouble that the entire switch device becomes large, and therefore the slide operation of the slide cover (3) cannot be performed by a short fingertip movement. Another trouble such as occurred.

The present invention seeks to solve the above problems.

[Means for Solving the Problem] In the switch device as described above, the present invention provides a groove or hole in which the slide plate interlocked with the power save switch is engaged and disengaged by the operation in the recording button which is the push button. I suggest that.

[Embodiment] FIG. 3 shows a plan view of a video camera (5) equipped with a recording switch device (4) of the present invention.

That is, (6) is a viewfinder, (7) is a grip part, a zoom switch (8) is provided on the upper surface of the grip part (7), and a recording switch device (4) is provided on the rear side face. .

Details of the recording switch device (4) are shown in FIGS. 1 and 2, FIG. 1 is a view taken in the direction of arrow A in FIG. 3, and FIG. 2 is a side sectional view.

The recording switch device (4) of this embodiment includes a recording button (9) as a push button, a slide plate (10) slidably provided above the button (9), and a slide plate (10). Connected power save switch (1
1) and the recording button (9) has a tact switch (1
It is connected to 2).

(13) is a casing of the video camera (5), (14) is an elongated hole formed in the casing (13), and the connection between the slide plate (10) and the power save switch (11) is this elongated hole ( Power save switch (1) on the U-shaped connection (10a) from the slide plate (10) that extends through
This is done by engaging the operator (11a) of 1).

The slide plate (10) of this example is formed in a trapezoidal finger rest (10b) having a fine groove (15) for sliding operation at the upper part, and a U-shaped part having a lower part divided into two parts. It is formed on the part (10c).

Further, a cutout groove (16) into which the U-shaped portion (10c) can be inserted is formed in an intermediate portion of the cylindrical body of the recording button (9).

This notch groove is formed at the same position as the track of the U-shaped portion (10c) in the free state where the recording button (9) is not pressed with a finger, and the U-shaped portion (10c) is After entering the notch groove (16), the recording button (9) cannot be pressed.

Since the device of this example is as described above, if the slide plate (10) is positioned upward as shown in FIGS. 1 and 2, the power save switch (11) will be turned off. All the circuits necessary for the operation are activated, and the recording button (9) can be pressed any time, so that whenever a photo opportunity occurs, recording can be immediately started corresponding to it.

Also, if the slide plate (10) is lowered to the position shown by the chain line in Fig. 1, the power save switch (11) will be turned on and some circuits necessary for the recording operation will be turned off. The recording button (9) is locked by the engagement of the U-shaped portion (10c) and the cutout groove (16) so as to prevent the start of recording.

Then, the slide plate (10) has a trapezoidal finger rest (10
Since the height (h) of b) is lower than the record button (9) and is far from the record button (9), the slide plate (10) becomes an obstacle when operating the record button (9). Moreover, since the U-shaped portion (10c) engages with the notch groove (16), the recording button (9) can be locked reliably. Moreover, the slide plate (10) has the same buttons (9) as the slide cover (3) of the conventional device.
On the other hand, the power save switch (11) can be turned on and off simply by sliding it linearly, so it also has the simplicity of operation of the engaging device.

The U-shaped portion (10c) may be formed in an L-shape as shown in FIG. 4 by omitting one arm portion, or as shown in FIG. It may have only 10d), and a hole (17) through which the arm (10d) can enter may be formed on the recording button (9) side.

Of course, the shape of the finger rest (10b) of the slide plate (10) can be variously modified.

[Advantages of the Invention] As described above, in the recording switch device of the present invention, the operation of the recording (recording) button is easy and the recording (recording) button is securely locked.
