For this reason, the position C of the press-fitting rib portion 1 a is such that the grip holding portion 1 d of the terminal cover 1 can suppress the excess length of the grip belt 6 when the press-fitting rib portion 1 a is press-fitted into the hole portion 3 a of the grip belt through fitting 3. It is arranged to be in position. That is, when the terminal cover 1 is in the open holding state, the extra length portion 6 a of the grip belt 6 is held down by the grip belt holding portion 1 d of the terminal cover 1. For this reason, the extra length portion 6 a does not cover the connection terminal 5, and it is easy to insert a plug into the connection terminal 5.

  FIG. 5 is an external view for explaining the rotation restriction of the terminal cover according to the embodiment of the present invention.

  As shown in FIG. 5, when the terminal cover 1 is opened and the terminal cover 1 is held by the grip belt loop fitting 3 by the press-fitting rib portion 1a, the terminal cover 1 rotates in the direction shown by the arrow. Power is working. Therefore, the standing wall D is configured to abut the grip belt loop fitting 3 to prevent the terminal cover 1 from rotating.

  FIG. 6A is an external view for explaining the relationship among the press-fitting rib portion, the standing wall portion, and the exterior surface of the terminal cover according to the embodiment of the present invention. FIG. 6B is a sectional view for explaining the relationship among the press-fitting rib portion, the standing wall portion, and the exterior surface of the terminal cover according to the embodiment of the invention. In FIG. 6A, the grip belt loop fitting and the grip belt are omitted.

  As shown in FIG. 6B, the press-fit rib portion 1 a is arranged so that the upper surface E of the press-fit rib portion 1 a comes into contact with or is close to the standing wall surface 7 of the imaging device 10 when the terminal cover 1 is closed. . Therefore, when the terminal cover 1 is closed, the upper surface E of the press-fitting rib portion 1 a serves as an insertion guide for the terminal cover 1.

  As shown in FIG. 6B, the press-fitting rib portion 1a is arranged so that the front surface F of the press-fitting rib portion 1a is in contact with or close to the exterior surface 8 of the imaging device 10 when the terminal cover 1 is closed. Has been. Accordingly, when the terminal cover 1 is pushed from the outside with the terminal cover 1 closed, the front surface F of the press-fitting rib portion 1a hits the exterior surface 8, and the terminal cover 1 does not move. That is, the front face F plays a role of receiving static pressure.

  FIG. 7 shows an external view in which a cable 9 is hooked on the terminal cover 1 according to the embodiment of the present invention. In the present embodiment, two types of hooking methods as illustrated in FIGS. 7A and 7B are illustrated. In FIG. 7, the press-fitting rib portion 1 a of the terminal cover 1 and the hole portion 3 a of the grip belt loop fitting 3 are omitted in order to clearly show the configuration in which the cable 9 is hooked on the terminal cover 1. As shown in FIGS. 7A and 7B, the terminal cover 1 made of an elastic member is provided with a plurality of ribs 2, and the ribs 2 are notched for hooking the cable 9. Portions 2a, 2b, 2c, 2d, 2e, and 2f are provided.

  As shown in FIGS. 7A and 7B, the cable 9 can be hooked in a plurality of ways with respect to the arrangement of the notch portions of the rib 2. In the method of FIG. 7A, the order of hooking the cable 9 after inserting the plug 9a is the order of the notches 2d, 2c, 2b, 2a, 2f, and 2e. In the method of FIG. 7B, the order of hooking the cable after the plug 9a is inserted into the connection terminal 4b is the order of the notches 2b, 2c, 2d, 2f, and 2e.

  The notches 2b, 2d, and 2e are disposed on the rib 2 on the same surface. Therefore, the cable 9 can be hooked without being in a straight line by either of the methods shown in FIGS. 7A and 7B. By doing so, even if the cable 9 is inadvertently pulled in the direction of the arrow, the plurality of ribs 2 will not absorb the force and the plug 9a will not come off.

  Note that, as shown in FIG. 7B, the terminal cover 1 is connected to the imaging apparatus main body by the arm portion 1b, and the arm portion 1b serves as a stopper so that the terminal cover does not come off. .

  FIG. 8 shows a cross-sectional view of the terminal cover 1 in this example when it is cut along a plane that passes through the notches 2d, 2d, and 2e (a line AA in FIG. 7A). For the sake of explanation, the cable 9 is omitted from the drawing. Here, the notch 2b and the connection terminal 4a, and the notch 2d and the connection terminal 4b are in a position overlapping when viewed from the direction orthogonal to the optical axis. For this reason, even if the plug 9a is inserted into the connection terminal 4a or the connection terminal 4b, the cable 9 can be hooked on the notch 2b or 2d without bending.

The notches 2b and 2e are notched in a plurality of circular shapes having different diameters. As represented by the following formula, the terminal cover 1 is formed to have a smaller diameter as it goes in the center direction (the notch 2d direction).
Φd1>x>φd2> 2r
Where x is the size of the opening, d1 is the diameter of the great circle, d2 is the diameter of the cable 9 in this embodiment, and r is the radius of the small circle.

  Therefore, it is possible to properly hook cables having different thicknesses. For example, the diameter φd2 of the cable 9 is smaller than the opening x. Therefore, the cable 9 can enter the notches 2b and 2e. However, the diameter φd2 of the cable 9 is larger than the diameter 2r of the small circle portion. Therefore, if the cable 9 is pushed into the small circle side, it can be hooked on the notches 2b and 2e.

  The notches 2b and 2e have an undercut shape for the reason of the mold, but can be integrally formed by using a mold structure such as a slide.

  FIG. 9 is a cross-sectional view for explaining the relationship between the rib portion of the terminal cover and the exterior surface when the terminal cover according to the embodiment of the present invention is closed.

  As shown in FIG. 9, when the terminal cover 1 is closed, the rib 2 is disposed so as to contact or be close to the exterior surface 5 of the imaging device. Therefore, when the terminal cover 1 is pushed from the outside in the direction of the arrow with the terminal cover 1 closed, the terminal cover 1 does not move when the rib 2 hits the exterior surface 5, and the rib 2 serves as a static pressure receiver. Plays.

  FIG. 10 is a block diagram showing an internal configuration of a digital video camera as an electronic apparatus.
