[Prior art]

 Nowadays, it is widely used in the world to shoot a memorable scene using a VTR (video camera) with a built-in camera.

The conventional video camera shown in FIG. 5 is handled by passing a hand 4 through a grip belt 3 provided on one side of the camera housing 2. An operation button for operating the device is provided at a position of the camera housing 2 that substantially corresponds to the fingertip of the hand 4 that has passed through. For example, it is known that there is a zoom button 5 for zooming (enlarging / reducing) during photographing at positions substantially corresponding to the fingertips of the index finger 4a and the middle finger 4b. This video camera is provided with a well-known camera unit for converting an optical image into an electric signal and a well-known recording unit for recording the converted electric signal on a magnetic tape of a tape cassette in the camera housing 2. .

In the conventional video camera, the position of the above zoom button 5 cannot be adjusted. Therefore, for example, one end 3a of the grip belt 3 is slidably adjusted in the arrow X1-X2 direction so that the operation of the zoom button 5 can be favorably performed with the fingertip in response to the change of the fingertip position depending on the size of the hand. There was an adjustment mechanism to do this.

For example, in the case of a person with a small hand and a short finger, as shown in FIG. 6A, one end 3a of the grip belt 3 is slid in the X1 direction so that the handling position is slightly above. The index finger 4Sa and the middle finger 4Sb of the small hand 4S are made to reach the zoom button 5 easily. On the contrary, in the case of a person with a large hand and a long finger, one end of the grip belt 3 is slid in the X2 direction as shown in FIG. 6 (b) so that the handling position is slightly lower. The fingertips of the forefinger 4La and the middle finger 4Lb of the large hand 4L were set so that the zoom button 5 could be pressed properly.

[Problems to be solved by the device]

 Good handling is important for this type of video camera, and the grip design of the camera housing 2 is designed so that it can be held in the palm of your hand in consideration of weight and balance.

However, in the conventional video camera, the grip belt 3 itself is moved to change the handling position so that anyone can operate the zoom button 5 satisfactorily. There was a risk that basic handling would deteriorate in exchange for various operations.

[0008]

[Means for Solving the Problems]

 The present invention solves the above-mentioned problems. The grip belt provided on one side of the camera housing can be handled by hand, and the device can be operated at a camera housing position substantially corresponding to the fingertip of the hand. A video camera provided with a button, comprising a position adjusting mechanism capable of variably fixing the position of the operation button according to the position of a fingertip.

【Example】

 Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 is an overall perspective view showing an embodiment of a video camera of the present invention, FIG. 2 is a partial perspective view showing a position adjusting mechanism of a zoom button of the video camera, and FIGS. 3 (a) and 3 (b) are FIG. 4A and FIG. 4B are partial cross-sectional views for explaining the position adjusting mechanism of the zoom button, and FIGS. 4A and 4B are explanatory views showing usage states of the video camera, respectively. Since the video camera described in the present embodiment has substantially the same configuration as the above-mentioned conventional example, substantially corresponding components are designated by the same reference numerals.

The video camera 1 shown in FIG. 1 is handled by passing a hand 4 through a grip belt 3 provided on one side of the camera housing 2. The hand 4 is inserted into the space K formed between the grip belt 3 and the camera housing 2, and the device operation is performed at the position of the camera housing 2 which substantially corresponds to the fingertip of the hand 4 thus passed. An operation button for performing is provided. For example, a zoom button 5 for zooming (enlarging / reducing) during photographing is provided at positions substantially corresponding to the fingertips of the index finger 4a and the middle finger 4b. The zoom button 5 is a seesaw type push button, and since such a technique is well known, the description thereof is omitted here.

The video camera 1 is provided with a position adjusting mechanism 10 for adjusting the position of the zoom button 5 so that the zoom button 5 can be moved with the fingertip even if the fingertip position varies depending on the size of the hand. The device is designed so that it can be operated well. The configuration of the position adjusting mechanism 10 for the zoom button 5 will be described below with reference to the drawings.

As shown in FIG. 2, the zoom button 5 is provided on the curved surface 11a of the support body 11 which is curved in a generally semi-cylindrical shape. A curved surface portion 2a is formed at a position of the camera housing 2 substantially corresponding to the fingertip positions of the middle finger and the forefinger, and a storage hole 12 for storing the support 11 is formed therein. Opposing surfaces 2b, 2c (see FIG. 3A) of the camera housing 2 that face each other with the storage hole 12 in between are connected by a shaft 13. A shaft hole 11c penetrating both side surfaces 11a and 11b is formed in the support body 11, and the support body 11 is rotatable in the A1-A2 direction about the shaft 13 in the housed state. The A1-A2 direction is the fingertip direction in the handling state.

Since the position of the support body 11 provided with the zoom button 5 becomes unstable if left as it is, this position adjusting mechanism 10 is provided with a mechanism for positioning the support body 11. As shown in FIGS. 3 (a) and 3 (b), several locking holes 14a to 14d of the same shape are continuously formed on the side surface 11b of the support 11 in the circumferential direction about the axial position. ing. On the other hand, a space 16 in which a lock member 15 that can be locked in the locking holes 14a to 14d is located is formed in the camera housing 2. The substantially L-shaped lock member 15 is displaceable only in the B1-B2 direction within the space 16, and has a lever portion 15a protruding above it through a hole 17 formed in the camera housing 2. The lock member 15 is biased in the B2 direction by a spring member 18, and is provided at one end in the biasing direction (B2 direction) with a locking portion 15b that can enter one of the locking holes 14a to 14d of the support 11. .

Therefore, pull the lever portion 15a to displace the entire lock member 15 in the B1 direction, and release the engagement between the engagement holes 14a to 14d of the support 11 and the engagement portion 15b of the lock member 15. For example, the support 11 can be rotationally displaced in the A1-A2 direction. When the lever portion 15a is released after adjusting the rotation position of the support body 11 according to the fingertip position (fingertip length) according to the size of the hand, the lock member 15 is displaced in the B2 direction by the biasing force of the spring member 18. Then, the engaging portion 15b enters the closest engaging hole 14a to 14d of the support 11. In the example illustrated in FIG. 3B, the locking portion 15b of the lock member 15 has entered the locking hole 14d. In this way, the support 11 provided with the zoom button 5 is in the positioned state.

Next, the usage state of the video camera 1 will be described with reference to FIGS. First, FIG. 4 (a) shows a case where a person with a relatively small hand and a short finger handles it. As shown in the figure, the support body is rotated in the A 1 direction by using the position adjusting mechanism 10 described above, and the zoom button 5 comes to a position substantially corresponding to the index finger 4Sa of the small hand 4S and the fingertips of the middle finger 4Sb. By fixing it like this, even such a person can operate the zoom button 5 satisfactorily with the fingertip. On the other hand, FIG. 4 (b) shows a case where a person with a relatively large hand and a long finger handles the object. As shown in the figure, the support 11 is rotated in the A2 direction using the position adjusting mechanism 10 described above, and the zoom button 5 is moved to a position substantially corresponding to the index finger 4La of the large hand 4L and the fingertips of the middle finger 4Lb. By fixing the zoom button 5, even such a person can operate the zoom button 5 with good fingertips.

In such a video camera 1, a position adjusting mechanism 10 for adjusting the position of the zoom button 5 for performing zooming, which is one of the device operations, is provided to reduce the size of the hand due to the difference between men and women and the age. Since the position of the zoom button is variably fixed according to the change in the fingertip position accompanying it, anyone can perform the zooming operation satisfactorily with the fingertip. Unlike the conventional example that achieves the purpose, there is no need to change the handling position, which is a great advantage that anyone can ensure good handling.

In this embodiment, the zooming operation by the zoom button 5 is taken as a representative example of the device operation performed with the fingertip, but the present invention is not limited to this. For example, this kind of video camera usually has a recording pause button (not shown) for turning on / off the recording pause at the position of the thumb (shown by 4c in FIG. 1) of the hand passed through. Of course, the technical idea of the present invention may also be applied here.

[0019]

[Effect of device]

 From the above description, the video camera of the present invention is provided with a mechanism for adjusting the position of the operation button for operating the device, and zooms in correspondence with the change in fingertip position due to the difference in hand size due to gender difference and age difference. Since the position of the button is variably fixed, not only can anybody operate the device with his or her fingertip, but the handling position is different from the conventional example in which the grip belt is moved to achieve the same purpose. Since there is no need to change the, there is a great advantage that anyone can ensure good handling.
