The main body cabinet 3 forming the outer shell of the main body recording unit 1 and the camera cabinet 9 forming the outer shell of the video camera unit 2 have respective side surfaces 3a and 9 respectively.
They are arranged so as to face each other with a small interval d (ｍｍ1.5 mm). Therefore, there is always a gap 19 ′ between the side surface 3 a of the main unit cabinet 3 and the side surface 9 a of the camera unit cabinet 9.

FIG. 14 is a sectional view showing the structure of a rotary connecting mechanism 15 'of a video tape recorder integrated with a camera. In addition, a similar thing about this rotation connection mechanism is described in Unexamined-Japanese-Patent No. 6-95212 and 7-296901.

A main body frame 4 is fixed to an inner side surface of the main body cabinet 3 with screws (not shown) or the like. A camera frame 10 is fixed to the inner surface of the camera cabinet 9 with screws (not shown) or the like.

The rotation connection mechanism 15 'physically connects the main body cabinet 3 and the camera cabinet 9 to each other in a relatively rotatable state, and has the following configuration.

A sliding rotation member 6 is in contact with the inner surface of the main body frame 4, and a fixed angle 5 is in contact with the inner surface of the sliding rotation member 6. The elastic sliding and rotating member 7 is in contact with the outer surface of the elastic sliding and rotating member 7, and the fixing member 8 ′ is in contact with the outer surface of the elastic sliding and rotating member 7. By the fastening, the fixed angle 5, the sliding and rotating member 6, the elastic sliding and rotating member 7, and the fixed member 8 'are integrally connected.

The elastic sliding and rotating member 7 is a disk-shaped member.
An annular thick portion on the inner peripheral side, an annular thin portion extending outward from the outer peripheral surface of the thick portion, and an annular rim portion connected to the outer peripheral surface of the thin portion. It is composed of The inner end face of the thick portion on the inner peripheral side is in contact with the main body frame 4 and the fixing member 8 '. The inner end surface of the outermost rim portion is in contact with the main body frame 4, but its outer end surface is opposed to the fixing member 8 'at a small interval (not shown). By tightening the connecting member 16, the annular thin portion of the elastic sliding rotation member 7 is elastically deformed, and an appropriate load is applied to the main body frame 4 from the annular rim. . The inner peripheral surface of the main body frame 4 is rotatably fitted to the outer peripheral surface of the thick portion of the elastic sliding and rotating member 7. That is, the main body frame 4
Is held between the sliding rotating member 6 and the elastic sliding rotating member 7 with an appropriate load, and is capable of sliding and rotating with a uniform torque when a rotating operation force is applied. It is in a state.

In order to connect the camera unit cabinet 9 to the main unit cabinet 3 in the rotation axis direction in a state of preventing detachment, a connecting member 17 'such as a screw is connected to the camera unit frame 10, the fixing member 8' and the elastic member. The plurality of members are fixedly connected through the sliding rotation member 7, the sliding rotation member 6, and the fixed angle 5. A part of the outer peripheral surface of the fixing member 8 ′ is rotatable relative to the inner peripheral surface of the main body cabinet 3, and the remaining part of the outer peripheral surface is integrally rotated with the inner peripheral surface of the camera cabinet 9. Has been fixed to be.

On the other hand, what is integrated by the above-described structure is that the camera unit cabinet 9, the camera unit frame 10, the fixed member 8 ', the elastic sliding and rotating member 7, and the sliding and rotating member 6 are integrated. , The fixed angle 5, the connecting member 16 and the connecting member 17 ', while the main body cabinet 3 and the main body frame 4 are integrated. Therefore, the main part of the rotation connection mechanism 15 'is
It can be said that it is one with the side. The connecting member 16 and the connecting member 17 ′ do not penetrate the main body frame 4. Therefore, the main body frame 4 and the main body cabinet 3 are connected to the camera cabinet 9, the camera frame 10, and the rotational connection. It is rotatable relative to the mechanism 15 '.

Fixed angle 5, sliding and rotating member 6, elastic sliding and rotating member 7, fixed member 8 'and camera frame 1
0, a through hole is formed in each of the central side portions,
The circuit of the main body recording unit 1 and the video camera unit 2
Flexible Printed Circuit (FP)
C) and the like are wired.

Main body cabinet 3 and main body frame 4
In a state in which the video camera unit 2 (camera unit cabinet 9) and the main body recording unit 1 (main unit cabinet 3) are positioned around the rotation connecting mechanism 15 ', the upper side of the video camera unit 2 The part can be rotated back and forth over a range of about 270 degrees, which is about 180 degrees forward and about 90 degrees beyond. Camera frame 1
A stopper (not shown) for restricting the above-mentioned rotation range of about 270 degrees between 0 and the fixing member 8 'is provided.

In the rotation stopped state, a gap 19 'is formed between the side surface 3a of the main body cabinet 3 and the side surface 9a of the camera cabinet 9.

Next, the operation will be described. When the main body recording unit 1 and the video camera unit 2 are relatively rotated, the main unit cabinet 3 and the main unit frame 4 integrated with the main unit cabinet 3 become
The camera unit 9 and the camera unit frame 10 rotate relative to the rotation connection mechanism 15 ′. As a result, the orientation of the main body recording unit 1 is changed while the video camera unit 2 is facing the subject, or the orientation of the video camera unit 2 is changed while the main body recording unit 1 is facing forward. The user can use the camera in a desired style, such as searching for a subject to be photographed. For example, a state in which the camera lens side of the video camera unit 2 is aimed at the subject, and the subject is photographed while visually confirming the subject image displayed on the liquid crystal display panel 1a of the main body recording unit 1;
The camera lens unit 2d can be used in such a manner that the operator switches the camera lens unit 2d to a state in which the user himself or herself is photographed while visually confirming the operator's image displayed on the liquid crystal display panel 1a with the operator facing the operator. .

At this time, the main body frame 4 is sandwiched between the sliding / rotating member 6 and the elastic sliding / rotating member 7 so that the elastic sliding / rotating member 7 is Since the load is applied, the torque of the relative rotation becomes substantially constant.

The gap 19 'is always open both during the rotation and in the state where the rotation is completed.

[0018]

In the above-described rotary connection mechanism of a camera-integrated video tape recorder according to the prior art, the main body cabinet 3 and the camera cabinet 9 are relatively rotated during photographing. However, at this time, if the side surfaces 3a and 9a of both cabinets 3 and 9 are in contact with each other, the relative rotation with a uniform torque is hindered by the contact resistance. However, if the captured image is blurred or a sound is generated at the time of rotational sliding, there is a possibility that the rotational sliding sound enters the microphone and is recorded as noise.

Therefore, as a countermeasure against this problem,
In the illustrated conventional technique, a gap 19 'having an appropriate dimension (around 1.5 mm) is provided between the side surface of the main unit cabinet 3 and the side surface of the camera unit cabinet 9 (d in FIG. 13A).
), The side surfaces 3a, 9a of both cabinets 3, 9 are previously separated from each other so that the side surfaces 3a, 9a of both cabinets 3, 9 do not slide during relative rotation. . In addition, the rotation connection mechanism 1
Sliding occurs at the portion 5 ', but this does not cause the above-mentioned problems so much.

However, since a gap 19 'is constantly formed between the side surfaces 3a and 9a of the cabinets 3 and 9, the quality of the camera-integrated video tape recorder is low, and the appearance is high. There is a problem of lack of feeling.

The problem of low quality and lack of high quality due to the gap between the two cabinets is that the main body recording unit 1 and the video camera unit 2 are relatively connected via the rotary connecting mechanism 15 '. This may occur not only in a camera rotation type video recording device such as a camera-integrated video tape recorder that is rotatably connected but also in other devices. For example,
This also applies to the case where a speaker or a sound collecting microphone is connected to the apparatus main body cabinet so as to be relatively rotatable.

The present invention has been made in view of such circumstances, and there is no gap between the side surface of the main unit cabinet and the side surface of the accessory unit cabinet in the rotation stopped state or the non-use state. Rotation of the equipment cabinet that is suitable for the production of high-quality equipment with high-quality appearance and high-quality appearance, and enables the relative rotation between the main body cabinet and the accessory cabinet to be performed with uniform torque with low contact resistance. It is intended to provide a coupling mechanism. Further, in addition to the above object, a camera rotation type video recording device which includes such a rotation connection mechanism and can prevent shooting and recording of a subject accompanied by blurring due to sliding resistance, and a camera shake similarly. It is an object of the present invention to provide a camera-rotating video recording / reproducing apparatus which can prevent recording and recording accompanied by sliding noise and perform a reproducing operation without such an adverse effect. These apparatuses are usually provided with a microphone, and are intended to prevent a problem that a rotation sliding sound due to sliding resistance enters the microphone and is recorded as noise.

FIGS. 1 and 6 show the stopped state of the rotation of the camera-integrated video tape recorder. 1 and 6 correspond to a special non-use state, that is, a storage posture in which the main body recording unit 1 and the video camera unit 2 are in a normal posture relationship. However, this is not the case, and any posture may be used as long as the rotation is stopped. Needless to say, the photographing may be performed in such a posture.

In this rotation stopped state, as shown in FIG. 4, the triangular protruding cam portion 13a of the cam member 13 exactly matches the triangular concave cam portion 8a of the fixing member 8. Since the cam member 13 is pressed against the fixed member 8 along the direction of the rotation axis by the urging force of the compression spring 11, and the corresponding meshing state is maintained, the cam member 13 is shown in FIG. As described above, the side surface 9a of the camera unit cabinet 9 of the video camera unit 2 is in contact with, ie, in close contact with, the side surface 3a of the main unit cabinet 3 of the main body recording unit 1, and as a product of a camera-integrated video tape recorder. Good quality and high quality appearance.

FIG. 7A shows a normal posture state in which the video camera unit 2 is parallel to the main body recording unit 1.

The camera lens unit 2d of the video camera unit 2 changes according to the change of the subject to be photographed and the change of the position of the photographer.
When the video camera unit 2 is rotated relative to the main body recording unit 1 in order to aim the camera unit cabinet 9
The camera unit frame 10 relatively rotates, and the pressing plate 12, the compression spring 11, and the cam member 13 of the rotation connection mechanism 15 are integrated with the fixing member 8 via a connection member 17 such as a stepped screw. Relative rotation. Then, FIG.
As shown in FIG. 3B, the cam member 13 is relatively rotated with respect to the fixed member 8 by the rotation connecting mechanism 15 so that the cam member 13 protrudes from the inclined surface of the concave cam portion 8a of the fixed member 8. The slope of the portion 13a slides relatively, and the force acting in the cam action at this time causes the component force in the direction of the rotational axis to be applied to the compression spring 1.
As shown in the cross-sectional view of FIG. 8 showing the state in the middle of the rotation, the urging force of the compression spring 11 is opposed (the compression spring 11 is flat). On the other hand, the cam member 13 moves relatively apart in the range of the predetermined small dimension d along the direction of the rotation axis, and the video camera unit moves with respect to the side surface 3a of the main body cabinet 3 of the main body recording unit 1. The side surface 9a of the second camera unit cabinet 9 is separated along the direction of the rotation axis, and a gap 18 is formed between the side surfaces of the two cabinets 3 and 9. FIG. 7 (b),
(C) indicates that the video camera unit 2 is 5
It turns about 10 degrees, indicating that a gap 18 is formed between the side surface of the main unit cabinet 3 and the side surface of the camera unit cabinet 9.

In this case, FIGS. 9A and 9B
The relationship between torque and force will be described with reference to FIG.

The rotation torque Mk of the rotation connection mechanism 15 shown in FIG. 9A is determined by the load generated by a certain amount of deformation of the elastic sliding rotation member 7 and the sliding rotation of the main body frame 4. This torque is generated according to the coefficient of friction between the member 6 and the elastic sliding rotation member 7. As shown in FIG. 9B, when a torque Mc smaller than the rotation torque Mk is applied, the cam member 13 is relatively separated from the fixed member 8 along the rotation axis direction. The coefficient of friction between the inclined surface of the recessed cam portion 8a and the inclined surface of the protruding cam portion 13a (and, consequently, their material), so that the force F is greater than the biasing force P by the compression spring 11, and The angle of the slope, the spring constant of the compression spring 11, the amount of deformation of the elastic sliding / rotating member 7, the main body frame 4, the sliding rotating member 6, and the elastic sliding / rotating member 7.
It is only necessary to set the coefficient of friction (and their material) between them. Of course, the urging force P of the compression spring 11 is set to be large enough to mechanically hold the video camera unit 2 with respect to the main body recording unit 1. At this time, Mk> Mc and F> P. That is, the torque M at the time of relative rotation between the main unit frame 4 of the main unit cabinet 3 and the camera unit frame 10 of the video camera unit 2.
As compared with k, the torque Mc at the time of the separation movement between the recessed cam portion 8a of the fixed member 8 and the protruding cam portion 13a of the cam member 13 in the direction of the rotation axis is set smaller.

In this manner, with the relative rotation of the camera unit cabinet 9 with respect to the main unit cabinet 3, the side surface 9 a of the camera unit cabinet 9 moves along the rotation axis with respect to the side surface 3 a of the main unit cabinet 3. As the distance increases, as shown in FIGS. 7 (b), 8 and 9 (a),
A gap 18 is formed between the side surfaces 3a and 9a of both cabinets 3 and 9. The dimension d of the gap 18 increases proportionally as the relative rotation angle of the cam member 13 with respect to the fixed member 8 increases.

At this time, the stopper 13d of the cam member 13 shown in FIG. 4 relatively rotates within the stopper long hole 8d of the fixed member 8. In this rotating state, just before the slope of the protruding cam portion 13a crosses the vertex of the slope of the recessed cam portion 8a, the stopper 13d of the cam member 13 is turned off as shown in FIG. The fixing member 8 comes into contact with the end of the stopper long hole 8d. The relative rotation angle from the start of the relative rotation to the contact is 5 to 10
Degree, and the separation between the side surfaces 3a and 9a of both cabinets 3 and 9 starts immediately after the relative rotation starts.

The stopper 13d is a stopper long hole 8d.
In the relative rotation between the cam member 13 and the fixed member 8 after the contact with the cam member 13, the fixed member 8 rotates integrally with the cam member 13.

As described above, during the period in which the cam member 13 is relatively rotated with respect to the fixed member 8, no rotating power is transmitted from the fixed member 8 to the elastic sliding and rotating member 7.
When the cam member 13 is rotated integrally with the fixed member 8, the elastic sliding rotation member 7 is moved from the fixed member 8.
, The cam 13, the fixed member 8, and the elastic sliding rotating member 7 rotate integrally. Then, the elastic sliding rotating member 7 and the sliding rotating member 6 rotate relatively to the main body frame 4.

In the relative rotation after the stopper 13d is brought into contact with the stopper long hole 8d, the dimension d of the gap 18 provided between the side surfaces 3a, 9a of both cabinets 3, 9 remains unchanged. Dimension d of this gap 18
(See FIG. 8) is preferably about 0.5 to 1.5 mm. However, as described above, when the rotation is stopped in FIGS. 1 and 6, the side surfaces 3a and 9a of both cabinets 3 and 9 are in close contact with each other, so that the camera-integrated video tape recorder has a good quality as a product. A gap 1 between the side surfaces 3a and 9a of the cabinets 3 and 9 that are rotating relative to each other can have a high-class appearance.
Since the size of 8 has nothing to do with the sense of quality in the rotation stopped state, the gap d may be designed so that the dimension d is larger than 1.5 mm.

As described above, when the main body unit cabinet 3 and the camera unit cabinet 9 are relatively rotated during photographing, the side surfaces 3a and 9a of both cabinets 3 and 9 are separated from each other, and the problem of contact resistance occurs. The relative rotation with the uniform torque (Mk) generated according to the coefficient of friction between the main body frame 4 and the sliding rotation member 6 / elastic sliding rotation member 7 is possible. Thus, it is possible to prevent such a problem that the captured image is blurred and the rotation sliding noise enters the microphone and is recorded as noise as in the conventional example.

In this case, as described above, the torque Mk at the time of the relative rotation between the main unit frame 4 of the main unit cabinet 3 and the camera unit frame 10 of the video camera unit 2 is set.
, The concave cam portion 8a of the fixing member 8 and the cam member 1
If the torque Mc at the time of the separation movement in the direction of the rotation axis with respect to the protruding cam portion 13a is set to be smaller, the operation of the separation by the cam action in the direction of the rotation axis is caused by the two cabinets 3. 9 is given a higher priority than the relative rotation,
The technical idea of separating the cabinets 3 and 9 and then rotating them relative to each other will be fully utilized.

A camera lens unit 2d for a desired subject
Is completed or the posture of the main body recording unit 1 is changed while the camera lens unit 2d is directed to a certain subject, and a desired shooting style is secured, that is,
The relative rotation of the video camera unit 2 with respect to the main unit recording unit 1, that is, the relative rotation of the camera unit cabinet 9 with respect to the main unit cabinet 3, is stopped. FIGS. 7D and 7E show a state in which the rotation of the video camera unit 2 at the desired angle with respect to the main body recording unit 1 has been completed.

As shown in FIGS. 7D and 7E, after the rotation at the desired angle is completed, the operation force of the relative rotation of the camera unit cabinet 9 with respect to the main unit cabinet 3 is released. However, as a result, the torque Mc applied to the cam member 13 disappears, and as a result, the concave cam portion 8a of the fixed member 8 which has been pressed against the tip of the slope until then.
In contrast, the projecting cam portion 13a of the cam member 13 relatively slides down to the home position along the rotation axis direction by the urging force of the compression spring 11, and the cam portion 13a moves relative to the recessed cam portion 8a. As a result, the protruding cam portions 13a are engaged with each other just in the same state, and the inner contact surface of the fixing member 8 and the inner contact surface of the cam member 13 are brought into close contact with each other. Accordingly, the stopper 13d of the cam member 13 is
To the center of the stopper long hole 8d. Further, the fixed member 8 is released from the integral rotation state with respect to the elastic sliding rotation member 7 and returns to a state in which it can be relatively rotated.

Then, the side surface 3a of the main body cabinet 3
As a result, the side surface 9a of the camera unit cabinet 9 is brought into close contact with the camera body 9 and the quality is good, and the state is restored to a high-grade appearance. 7D and 7E, the side surfaces 3a and 9a of both cabinets 3 and 9 are in close contact even after the video camera unit 2 is relatively rotated with respect to the main body recording unit 1. It shows the state that it is doing.

FIGS. 7D and 7E show the video camera unit 2 (camera unit cabinet 9) with respect to the main unit recording unit 1 (main unit cabinet 3). Is rotated about 30 degrees toward the opposite side (normal subject side), but can be rotated about 90 degrees toward the opposite side and about 180 degrees toward the near side (operator side).
It can be rotated by degrees.

The side surface 3a of the main body unit cabinet 3 and the side surface 9a of the camera unit cabinet 9 are separated from each other only when the two cabinets 3 and 9 are being rotated relatively. According to the first embodiment, as shown in (d) and (e) of FIGS. 6 and 7, the gap 18 is provided between the cabinets 3 and 9 during shooting in the rotation stopped state or in the non-use state. It is possible to make the appearance appearance high-grade without the quality.

When the main body unit cabinet 3 and the camera unit cabinet 9 are relatively rotated during photographing, the side surfaces of both cabinets 3 and 9 are separated from each other and the problem of contact resistance is eliminated, so that the uniformity is obtained. It is possible to perform relative rotation with a large torque, and to prevent problems such as blurring of a captured image and rotation sliding noise entering a microphone and being recorded as noise as in the conventional example. Can be.

In the first embodiment, the cam member 13, the compression spring 11, and the holding plate 12 are added as the rotation connection mechanism 15. Since the holes are formed, there is no hindrance to the wires of the flexible wiring member 14. When the main body recording unit 1 and the video camera unit 2 are rotated relative to each other, the load applied to the flexible wiring member 14 is absorbed by the expansion or contraction of the central spiral part, so that the flexible wiring member 14 breaks. There is no danger.

[Embodiment 2] A camera-integrated video tape recorder according to Embodiment 2 is similar to Embodiment 1 of the present invention.
Only the shape of the cam member 13 is different from that of FIG.
