  In the present embodiment, unlike the antenna 101, the transmission / reception circuit 100 is not provided at a position protruding from the camera body 1. That is, the transmission / reception circuit 100 is provided inside the metal exterior.

  This is because the transmission / reception circuit 100 is larger than the antenna 101, so that the antenna cover 11b is prevented from becoming large by using only the antenna 101 as a target to be protected by the antenna cover 11b.

  In addition, by providing only the antenna 101 that actually transmits and receives radio waves at a position protruding from the metal exterior part, it is possible to suppress a decrease in communication performance.

  Since the opening for passing the antenna substrate 101a through and inside the camera body 1 is used in combination with the opening 1b for passing the sync contact 11 into the camera body 1, the camera body 1 has a new opening. There is no need to process.

  Therefore, in this embodiment, the size of the antenna cover 11b can be reduced as much as possible without increasing the cost.

  The accessory shoe 12 is formed of a metal material. For example, various accessories having a shape that can be fitted into the accessory shoe 12 can be attached in addition to an external strobe (not shown).

  In addition, as a member of the accessory shoe 12, it is desirable to use a material having high conductivity and higher strength than the resin material of the antenna cover 11b described above.

  For example, even if the camera body 1 is accidentally dropped on the ground or the like, the accessory shoe 12 is brought into contact with the ground prior to the antenna cover 11b to protect the antenna cover 11b from the impact of dropping. In order to obtain sufficient strength. This point will be described later.

Accordingly, the user can observe the subject image converted into an erect image by the pentaprism 29 through the eyepiece lens group 30 through the eyepiece window 19a.

  From FIG. 6, in the present embodiment, the apex of the antenna cover 11b indicated by the alternate long and two short dashes line <2> from the apex (outermost part) of the accessory shoe 12 indicated by the alternate long and short dash line <1> in the upper part of the camera body 1. The part (outermost part) is arranged at the lower part (lower position).

  On the other hand, the two-dot chain line <2> shown above is the upper part (higher position) than the highest position of the metal exterior shown by the short broken line <3>.

  That is, the antenna cover 11 b is disposed at a position protruding (high) from the camera body 1 and not (lower) from the accessory shoe 12 than the metal exterior portion of the camera body 1. .

  The short broken line <3> is also the lower surface of the accessory shoe base 11. In addition, the line indicating the highest position of the metal exterior portion of the camera body 1 may be a line on the exterior configuration surface of the camera body 1 indicated by the short broken line <3 '> instead of the short broken line <3>.

  Further, it is not necessary that the antenna cover 11b protrudes from all parts of the accessory shoe 12. In the present embodiment, it is sufficient that at least the apex portion of the accessory shoe 12 that is the outermost part of the accessory shoe 12 is disposed at a position protruding from the antenna cover 11b.

  Therefore, even if the camera body 1 is accidentally dropped, the accessory shoe 12 made of a metal material comes in contact with the ground first than the antenna cover 11b made of a resin material. Can be protected.

  In addition, since the antenna 101 is above the line indicating the highest position of the metal exterior part of the camera body 1, radio waves used for wireless communication are not blocked by the metal exterior part, and the deterioration of communication performance can be suppressed. it can.

  In addition, you may comprise so that the antenna cover 11b may not protrude from the tangent with respect to a metal exterior part from 11f which is the highest position of the accessory shoe base 11, as shown with the long broken line <4>.

  Moreover, you may comprise so that the antenna cover 11b may not protrude from the upper part of the part protruded ahead of the accessory shoe 12 from the tangent with respect to a metal exterior part.

  In this case, since the antenna cover 11b has fewer portions protruding outside the camera body 1 than the parts of the camera body 1, the protection performance of the antenna cover 11b is further improved.

  Next, with reference to FIG. 7, an arrangement relationship of each part constituting the upper part of the camera body 1 when viewed from the front of the camera body 1 will be described. FIG. 7 is a view exemplarily showing a front view of the imaging apparatus according to the present embodiment as viewed from above.

  In the present embodiment, the lateral width B of the antenna cover 11 b provided integrally with the accessory shoe base 11 is configured to be narrower than the lateral width A of the accessory shoe 12.

  This is because, when the camera body 1 has fallen on the ground or the like, the accessory shoe 12 formed of a metal material is first brought into contact with the antenna cover 11b formed of a resin material.

  With the above configuration, even when the camera body 1 is accidentally dropped, the antenna cover 11b and the antenna 101 provided inside the antenna cover 11b can be protected.

  For example, when the accessory shoe 12 and the antenna cover 11b have the same lateral width, the ground and the antenna cover 11b may come into contact with each other when the upper portion of the camera body 1 falls obliquely downward with respect to the ground.

  Even in such a case, by making the width B of the antenna cover 11b narrower than the width A of the accessory shoe 12 formed of a metal material, the antenna cover 11b may come into contact with the ground by the difference between the width A and the width B. descend.

  Even if the antenna cover 11b and the ground come into contact with each other, the impact due to the contact can be reduced by the width A of the accessory shoe 12.

  As described above, according to the imaging apparatus according to the present embodiment, the antenna cover 11b including the antenna 101 can be arranged on the camera body 1 so as to suppress deterioration in wireless communication performance. .

  Further, even when the camera body 1 is accidentally dropped, the antenna cover 11b can be prevented from being damaged, and the antenna 101 provided inside the antenna cover 11b can be protected from the impact of dropping. it can.

  In the present embodiment, all the portions of the antenna cover 11b are disposed above the metal exterior portion of the front portion of the antenna cover 11b, but the present invention is not limited to this. Considering the blocking of radio waves by the metal exterior part, it is not always necessary that all parts of the antenna cover 11b be disposed above the metal exterior part of the camera body 1.

  For example, in order to ensure a certain level of communication performance, a configuration in which a metal exterior part is disposed on a part of the surface of the antenna cover 11b, particularly above the surface on which the antenna 101 is provided may be employed.

  In this case, the portion of the antenna cover 11b exposed to the outside with respect to the metal exterior portion of the camera body 1 is smaller than that in the above case.

  Therefore, the protection performance of the antenna cover 11b when the camera body 1 is accidentally dropped on the ground or the like is further improved.

  Further, by reducing the portion of the antenna cover 11b exposed to the outside, it is possible to reduce the size of the entire imaging apparatus while improving the high-quality appearance of the imaging apparatus.
