  The interchangeable lens 1 is provided with a lens side unique information storage unit 15 in which lens side unique information including at least the lens manufacturing number 2 of the interchangeable lens 1 is stored.

  The lens side unique information storage unit 15 is electrically connected to the operation button 32 and the cross key 33 via a display unit 31 provided in the camera body 30. The lens-side unique information including the lens serial number 2 stored in the lens-side unique information storage unit 15 is displayed on the display unit 31.

  FIG. 4 is a cross-sectional view of the interchangeable lens 1.

  The interchangeable lens 1 has two lenses L1 and L2 arranged on the optical axis O.

  The lens L1 is held in the lens chamber 6. The external thread portion 6 a formed on the outer peripheral surface of the lens chamber 6 is formed on the inner peripheral surface of the moving frame 7 fitted to the fixed cylinder 3, and is therefore screwed into the screw portion 7 a.

  On the outer peripheral surface of the moving frame 7 is provided a moving pin 8 that fits in a rectilinear groove 3b provided in the fixed cylinder 3 and extending in the optical axis O direction.

  The moving pin 8 is fitted in a cam groove 4 a formed on the inner peripheral surface of the operation ring 4 that is rotatably held by the fixed cylinder 3.

  By rotating the operation ring 4, the moving pin 8 linearly moves in the optical axis direction along the cam groove 4 a and the rectilinear groove 3 b of the fixed cylinder 3. At this time, the lens L <b> 1 moves in the direction of the optical axis O together with the moving frame 7 and the lens chamber 6 to perform focus adjustment.

  Further, the lens chamber 6 is provided with a light shielding portion 6b so that a storage card 18 and the like to be described later cannot be seen when the inside of the interchangeable lens 1 is viewed from the outside of the lens L1. The light shielding process may be performed on the storage card 18, the electronic board 17, the connector 19, the electronic component 20, and the like instead of the light shielding unit 6 b.

  The lens L2 is held by the fixed cylinder 3.

  The outer peripheral surface of the fixed cylinder 3 is covered with a protective cylinder 9 so that the electronic substrate 12 (described later) is not exposed to the outside. The protective cylinder 9 is fixed to the fixed cylinder 3 with screws 10.

  Connectors 13 and 21 are provided at both ends of the electronic substrate 12 in the optical axis O direction.

  A contact 11 for communicating with the camera body 30 is provided at one end of the fixed cylinder 3. One end of a lead wire 14 is connected to the contact 11. The other end of the lead wire 14 is connected to the connector 13 through a through hole 3 c provided in the fixed cylinder 3. The lead wire 14 transmits a signal between the contact 11 and the electronic substrate 12.

  Electronic components such as lens side unique information storage units 15 and 16 and elements 25 and 26 are mounted on the electronic substrate 12. The lens side unique information storage units 15 and 16 store the production number 2 of the interchangeable lens 1, respectively.

  On the inner peripheral surface of the fixed cylinder 3 (between the lens L1 and the lens L2), an electronic substrate 17 on which electronic components such as a storage card 18 are mounted is provided. The storage card 18 stores the serial number of the interchangeable lens 1.

  One end of a lead wire 22 is connected to the electronic substrate 17. The other end portion of the lead wire 22 is connected to the connector 21 through a through hole 3 d provided in the fixed cylinder 3. The lead wire 22 transmits a signal between the electronic substrate 17 and the electronic substrate 12. The through hole 3d has such a size that the electronic board 17 on which the storage card 18, the connector 19, and the electronic component 20 are mounted cannot pass. The electronic board 17 on which the memory card 18, the connector 19, and the electronic component 20 are mounted is fixed to the inner peripheral surface of the fixed cylinder 3 before the lens chamber 6 holding the lens L 1 is attached to the moving frame 7, and the lead wire 22 is attached. The through hole 3d is passed through and connected to the connector 21 of the electronic board 12.

  Here, it is assumed that the interchangeable lens 1 is stolen.

  A person who stole the interchangeable lens 1 may scrape the serial number 2 displayed on the outer peripheral surface of the interchangeable lens so that the owner is not known. However, since the interchangeable lens 1 is provided with the unique information storage unit 15, when the interchangeable lens 1 is attached to the camera body 30, the serial number 2 is displayed on the display unit 31, and the owner of the interchangeable lens 1 is determined. As a result, the interchangeable lens 1 is found to be a stolen product. Therefore, the person who stole the interchangeable lens 1 gives up the resale.

  It is also conceivable that a person who stole the interchangeable lens 1 uses the interchangeable lens 1 himself. However, when the interchangeable lens 1 is sent for repair, the interchangeable lens 1 is provided with the unique information storage unit 15 as described above, so that it is understood that the interchangeable lens 1 has been stolen from the serial number 2. . Therefore, the person who stole the interchangeable lens 1 gives up using the interchangeable lens 1 by himself / herself.

  As described above, even if the interchangeable lens 1 is stolen, it cannot be resold or used by itself, so that the stealing itself is given up or the stolen interchangeable lens is immediately released. As a result, the interchangeable lens 1 can be found as a lost item and easily returned to the owner.

  Furthermore, it may be considered that a person who stole the interchangeable lens 1 tries to prevent the serial number 2 of the interchangeable lens 1 from being displayed on the display unit 31 of the camera body 30. In that case, the person who stole removes the protective cylinder 9 of the interchangeable lens 1 from the fixed cylinder 3 by loosening the screw 10 and exposes the electronic board 12 so that the serial number 2 is stored. Is to be removed from the electronic board 12. However, even if the unique information storage unit 15 storing the production number 2 is removed, the unique information storage unit 16 storing the production number 2 remains, so that the interchangeable lens is displayed on the display unit 31 of the camera body 30. The serial number 2 of 1 is displayed. The person who stole the interchangeable lens 1 notices that the serial number 2 is also stored in the unique information storage unit 16 and tries to remove the unique information storage unit 16. However, if the elements 25 and 26 other than the unique information storage unit 16 are mistakenly removed, the interchangeable lens 1 will not function. Therefore, the person who stole gives up further work on the interchangeable lens 1 and gives up reselling or using it by himself. As a result, the interchangeable lens 1 returns to the owner as a lost item.

  Even if the person who stole can remove the unique information storage unit 15 and the unique information storage unit 16, the serial number 2 is also stored in the storage card 18, and the interchangeable lens 1 is attached to the camera body. When attached to the camera 30, the serial number of the interchangeable lens 1 is displayed on the display unit 31 of the camera body 30. As described above, since the through hole 3d has a size that the electronic board 17 on which the storage card 18, the connector 19, and the electronic component 20 are mounted cannot pass through, the electronic board 17 cannot be pulled out through the through hole 3d. Can not. In order to prevent the data of the serial number of the interchangeable lens 1 from being read from the storage card 18, it is necessary to remove the lead wire 22 from the connector 21. However, in addition to the memory card 18, the electronic component 20 is mounted on the electronic board 17, and the electronic component 20 does not function when the lead wire 22 is removed from the connector 21, so that the interchangeable lens 1 cannot perform its function. The person who stole can remove the memory card 18 from the connector 19 by removing the lens chamber 6 holding the lens L1 from the moving frame 7 so that the serial number is not displayed on the display unit 31 of the camera body 30. Even if the lens chamber 6 is incorporated into the moving frame 7 again, there is no guarantee that the optical performance will be restored. In order to restore the optical performance, the interchangeable lens 1 needs to be repaired. However, since there is no storage card 18 and neither the unique information storage unit 15 nor the unique information storage unit 16, the interchangeable lens 1 is stolen. I know that there is. Therefore, since the person who stole gives up reselling or using it as his own, even if the person is stolen, the possibility of returning is increased, and the theft itself is reduced.

  According to this embodiment, the production number 2 displayed on the exterior of the interchangeable lens 1 is displayed on the display unit 31 of the camera body 30, so that the production number 2 is increased regardless of the size restriction of the interchangeable lens 1. Since it can be displayed, the serial number 2 of the interchangeable lens 1 can be easily confirmed. Even if the serial number 2 of the external appearance of the interchangeable lens 1 may be scraped off, the serial number 2 is displayed on the display unit 31 of the camera body 30, so that the owner can easily understand and lead to theft prevention.

  The production number 2 may be notified by voice instead of being displayed on the display unit 31.

  Further, in addition to the manufacturing number 2 for each type of the interchangeable lens 1, a serial number through all the interchangeable lens molds may be provided. For example, it may be possible to have information on how many are specific mounts that have lasted for decades. If the interchangeable lens 1 is displayed with information indicating whether it is the cumulative number of tens of millions of users, a new satisfaction can be obtained for the user, and the manufacturer can provide benefits to the user. Is also possible.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  Since the structure of the camera system used in the second embodiment is the same as the structure of the camera system of the first embodiment, its illustration and description are omitted. The reference numerals are changed for each component in order to distinguish a plurality of components (interchangeable lenses and the like).
