In this way, the DC motor 38 is driven to switch between the retracted position and the image-capturing position and to perform the zoom operation in the image-capturing range. Further, when the drive ring 37 rotates, the finder lens (not shown) moves to the follower 6 as described above.
It moves in the optical axis direction along the cams 37d and 37e via 0 and 61 and interlocks with the zoom operation of the lens barrel.

At the same time, the lever 57 moves along the cam 37c in the optical axis direction to displace the slider 56a of the linear sensor 56 and change its output as shown in FIG. 11 (b). The zoom position can be sequentially detected by detecting this output.

FIG. 15 is a diagram showing three types of zoom drive modes provided in the camera of this embodiment. In the figure, the arrow indicates the zoom drive direction, W is wide, and T is tele.

In FIG. 15A, the target position is always driven by driving in one direction and stopped, whereby the effect of the backlash of the gear trains 39 to 45 can be absorbed and the positioning can be performed accurately. it can. At this time, the control unit 7
4 controls to apply a high voltage across the terminals of the DC motor 38 and is therefore driven at high speed. This allows the lens group to be positioned quickly.

In (b), the inversion drive as in (a) above is not performed on the target position, and the target position is stopped. This eliminates an unnatural change in the angle of view during movie shooting.
Further, the control unit 74 controls to lower the terminal voltage and is driven at a low speed. As a result, the driving sound during movie shooting can be kept low.

In (c), the biasing drive is performed again at the current stop position, and the positioning is performed at the same driving speed as in (a).

When the photographing mode is selected by the mode dial 76, the lens is extended and positioned at the wide position, and the photographing standby state is set (step S101). The driving here is performed according to the driving pattern shown in FIG. In this state, whether or not the zoom switch 77 and the release switch are operated is properly checked (steps S102 and S103).

When the zoom switch 77 is operated, the zoom switch 77 is driven in the tele direction or in the wide direction according to the command according to the drive pattern (a) of FIG. 15 (step S104), and after stopping, returns to the standby state of step S101. . When the release switch 79 is operated, the selection switch 7
8 is checked (step S105), and if a still image is selected, a still image is taken (step S10).
6). The shooting at this time may be a single shot in which only one image is shot, or continuous shooting in which images are continuously captured while the release switch 79 is being pressed, but a zoom operation is not accepted at the same time. After the shooting is completed, the process returns to step S101 in the standby state.

When the moving image is selected by the selection switch, the moving image shooting is started (step S107) and the shooting is continued until the next operation of the release switch 79. If the zoom switch 77 is operated during that time (step S108-
y), according to the command, it is driven in the tele direction or the wide direction by the drive pattern (b) of FIG. 15 (step S1).
09), shooting is continued. Then, when the release switch 79 is operated again (step S110-y), the photographing is ended (step S111), and repositioning is performed at the same position in the drive pattern (c) of FIG. 15 (step S111).
112) Return to the initial standby state (step S101).
