Become. When the second operation member 46 is at the fifth operation position and the operation member 20 is at the lower end position of the operation opening 43 (FIG. 5B), the close-up mode is set. When the second operation member 46 is in the fourth operation position and the operation member 20 is in the upper end position, the daytime synchro shooting mode is set, the second operation member 46 is in the fifth operation position, and the operation member 20 is operated. When is at the upper end position, the flash emission is performed during the close-up shooting to enter the close-up sync shooting mode.

  In the close-up shooting mode, the shooting lens 6 is switched to the close-up shooting position in front of the optical axis in accordance with the movement operation of the second operation member 46 to the fifth operation position. Further, a close-up finder field frame 49 (proximity field frame) for parallax correction and a target mark 50 are inserted in front of the finder 9, and a light shielding plate 51 is inserted in front of the strobe light emitting unit 10. The proximity field frame 49 is a field frame for correcting parallax caused by the deviation of the optical axis of the finder 9 and the optical axis of the photographing lens 8, and the target mark 50 is a main subject. Is a mark for copying the image at the center of the screen. The light shielding plate 51 cuts off a part of the strobe light to reduce the light, thereby preventing the exposure amount from exceeding.

  As shown in FIG. 6, in order to change the film unit 41 with a multi-function lens having a close-up mode, which has been recycled or newly manufactured, into a film unit with a standard lens, the main body 54 has an exterior rough bell 42. Instead, the exterior label 55 is attached. As with the above-described exterior label 30, the exterior label 55 is provided with various openings corresponding to the respective portions such as the raised portion opening 33 and the finder opening 34 provided in the unit main body 54, and is based on a plastic film. It is formed into a shape label.

  The exterior label 55 is provided with a second switching opening 56 at a position corresponding to when the second operation member 46 is in the fourth operation position. When the exterior label 55 is positioned and attached to the main body portion 54, the second operation member 46 is exposed from the second switching opening 56. Therefore, the movement of the second operation member 46 from the fourth operation position to the fifth operation position is restricted. As a result, the close-up mode cannot be used, and the film unit 41 with a multi-function lens can use only the function of the film unit with a standard lens. Therefore, the film unit 41 with a multifunctional lens can be easily changed to a film unit with a standard lens.

  In the present embodiment, the exterior label 42 to be attached to the main body 54 is changed to the exterior label 55, whereby the multifunctional lens-equipped film unit 41 having the close-up mode is changed to a standard lens-equipped film unit. However, instead of this, the film unit 41 with a multi-function lens may be changed to a film unit with a standard lens by replacing the front cover 47 assembled to the base of the main body.

  In this case, the front cover 47 of the multifunctional lens-equipped film unit 41 is replaced with a front cover 58 shown in FIG. The front cover 58 is provided with various openings that expose the photographing lens 8, the finder 9, the strobe light emitting unit 10, the operation opening 43 and the like at the same position as the front cover 47 of the film unit 41 with a multifunctional lens. . The front cover 58 at a position corresponding to the fourth operation position of the second operation member 46 is provided with a second opening 60 having an outer shape slightly larger than that of the second operation member 46. The front cover 58 is attached to the main body base with the second operation member 46 disposed at the fourth operation position. Thereby, the movement of the second operation member 46 from the fourth operation position to the fifth operation position is restricted by the second switching opening 60 and is fixed at the fourth operation position. Accordingly, the close-up mode cannot be used, and only the shooting mode of the standard lens-equipped film unit can be used. Therefore, the multifunctional lens-equipped film unit 41 can be easily changed to the standard lens-equipped film unit. it can.

  In the above embodiment, the movement of the operation member of the film unit with a multi-function lens having the night view shooting mode and the close-up shooting mode is restricted, and the film unit with the multifunction lens is changed to the film unit with the standard lens. However, the film unit with a multi-function lens may be changed to a film unit with a standard lens by restricting the movement of the switching member linked to the operation of the operation member 20 in the night scene shooting mode or the close-up shooting mode. For example, the upward movement of the dimming member 25 disposed in front of the strobe light emitting unit 10 is restricted in the night scene shooting mode.

  FIG. 8 shows a configuration of a switching mechanism for switching to the night scene shooting mode. The switching mechanism 65 is provided on the front cover (not shown) and the front surface of the circuit board of the strobe device, and includes an operation member 20, a light reducing member 25, a light reducing lever 66, a torsion spring 67, a light reducing protrusion 69, and the like. ing. When the operation member 20 is in the second operation position, the light reduction protrusion 69 and the lift piece 70 of the light reduction lever 66 abut. As a result, the operation member 20 is held at the second operation position by the bias of the torsion spring 67. Further, at the second operation position, the circular contact portion of the lift piece 70 and the flat cam portion of the dimming projection 69 are in contact.

  When the operating member 20 is operated to the third operating position, the light reducing lever 66 is attached to the torsion spring 67 by the lift piece 70 being pressed by the light reducing projection 69 in conjunction with the movement of the operating member 20. It rotates counterclockwise in the figure against the force. At that time, the light reducing plate 25 is lifted by the link pin 66 a and is inserted into the front of the strobe light emitting unit 10.

  A movement restricting member 72 that restricts the movement of the light reducing member 25 is provided on the back side of the front cover. When the front cover is attached to the main body base, the movement restricting member 72 is disposed on the light reducing member 25 housed in the main body base, as indicated by a dotted line in the figure. As a result, when the operation member 20 is operated to the third operation position, the dimming member 25 lifted upward in conjunction with the operation member 20 comes into contact with the movement restricting member 72 to the front surface of the strobe light emitting unit 10. Movement is restricted. Thus, the multifunctional lens-equipped film unit 2 having the night view mode can be easily changed to the standard lens-equipped film unit.

  In the above embodiment, a standard lens is attached by attaching an exterior label or a front cover for restricting the movement of the operation member for switching the photographing mode to the film unit with a multifunctional lens having the night view photographing mode and the close-up photographing mode. Although only the shooting mode of the film unit can be used, similarly, the switching movement to the shooting mode of the film unit with a standard lens may be restricted so that only the night scene sync shooting mode and the close-up shooting mode can be used. .
