Problems solved by technology

However, as described above, since the imaging element acts in the direction of the adjustment ring with a large force, a large motor is required to rotate the adjustment ring, and it is difficult to move the imaging element smoothly with a relatively small driving force generated by a small motor. subject
[0010] On the other hand, when the torque required to rotate the adjustment ring is reduced in order to smoothly move the imaging element in the direction of the optical axis, there is a problem that the adjustment ring will be distorted when an external force such as an impact is applied. Rotation, therefore, it is difficult to keep the stop position of the imaging element at the desired position

[0144] Next, an imaging device driving device 270 according to a third embodiment of the present invention will be described.

[0145] Figure 6 It is a diagram for explaining the configuration of the imaging device driving device 270 according to the third embodiment of the present invention. exist Figure 6 In , the movable part 203 and the driving part 220 in the configuration of the imaging element driving device 270 are described. Other structural elements, because with figure 1 The illustrated image pickup device driving device 70 is common, so detailed description is omitted.

[0146] Such as Figure 6 As shown, in the third embodiment of the present invention, the movable part 203 is rotated by the worm 221 attached to the shaft part 223 rotated by the driving part 220 . The worm 221 is held by the shaft portion 223 by the holding portion 222 so as not to fall off from the shaft portion 223 . Further, the driving unit 220 is provided on the surface of the base un...

Abstract

An imaging element driving device is provided with an imaging element holding section, which holds an imaging element by permitting an imaging plane to face a prescribed direction, and is movable in an optical axis direction; a movable section arranged to abut to the imaging element holding section; a driving section for shifting the imaging element, which is held by the imaging element holding section, in the optical axis direction by maintaining the planar direction of the imaging plane by operating the movable section; and a position holding force applying section for applying a position holding force for holding the position of the imaging element holding section in the optical axis direction.

Description

technical field [0001] The present invention relates to an imaging device such as a surveillance camera device or a camera device, and particularly relates to an imaging device drive device for moving an imaging device in the optical axis direction of a lens, and an imaging device using the same. Background technique [0002] First, the prior art of imaging devices will be described. Here, a surveillance camera device will be described as an example of a photographing device. [0003] In recent years, various technologies related to surveillance camera devices have been proposed. In particular, a technique has been proposed in which, in a surveillance camera device for day and night monitoring, during the day, an infrared cut filter that selectively transmits visible light and absorbs infrared rays is arranged in front of the imaging element to perform shooting; on the other hand, When shooting at night, remove the infrared cut filter arranged in front of the imaging eleme...
