By adjusting the size of the aperture hole opening, the amount of light entering the camera is the most: For best results. However, 'autofocus and aperture adjustment cameras have been used by most non-experts. With the advancement of technology, digital cameras have gradually replaced traditional cameras, and the design of digital cameras is also light, thin, short, and small. Design, therefore, the aperture device must also be developed in a compact direction. Existing camera aperture devices, such as the Republic of China Announcement No. 4 3 1 6 0 3 "Camera Composite Aperture Shutter Device", use an aperture shutter element at the aperture. The shutter element is provided with a plurality of apertures of different aperture sizes at intervals. The aperture shutter element is rotated by a driving device so that one of the apertures is covered by the aperture aperture. The size of the different apertures is changed to control the amount of light entering the camera. . However, due to the limited number of openings in the existing technical methods described above, the effect of aperture adjustment can only be limited to the number and size of the openings to produce a limited stepwise adjustment effect, that is, when changing When the number of openings is different, the increase in the number of openings is the number of adjustable sections of the aperture adjustment effect. This technical method of aperture adjustment cannot provide accurate control of the light input of the 1232999 camera, which will cause photographic quality. Not good. [Summary of the invention] The main object of the present invention is to provide a camera aperture device capable of stepless adjustment, so that the aperture device can accurately control the amount of light entering the camera and improve the quality of photography.

And includes a motor and a driving rod coupled to the motor and rotated by the motor, the adjusting device is movably disposed in the body accommodation space, and includes two aperture plates that move relative to each other, and each of the aperture plates has one The overlapping portions overlapped with each other and the long arms of the combined protruding pillars respectively connected to the driving rod. Each overlapping portion is provided with a notch corresponding to each other, the area surrounded by the two notches is aligned. To the aperture. Thus, the effects achieved by the present invention are as follows: (1) Since the rotation speed and angular displacement of the motor can be controlled and continuously output by the feeding controller for the fine dish, the aperture is controlled by controlling the motor The two notches on the film are moved toward or away from each other, which can precisely control and change the area surrounded by the two notches to achieve the effect of steplessly adjusting the aperture, so that the amount of light entering the camera is optimized and improved. The quality of photography. 1232999 (2) The adjustment device can be designed and manufactured in a modular manner to be applicable to various camera lenses, which can improve product compatibility and reduce the cost of design and manufacturing. [Embodiment] As shown in the first figure, the aperture device (10) of the present invention is provided in a lens barrel (20), and the lens barrel (20) is provided with a plurality of lenses. A slot is provided for receiving the aperture device portion. Please refer to the second and third figures, the aperture device (i 〇) includes a body (li), a driving device (12), an adjusting device (13) and an outer cover (14); the body ( 11) It is a hollow housing, one side of which is recessed with an accommodation space (iii) and four square positioning posts (i5) arranged in the accommodation space (iii), and the other side is provided with a combination seat (112), the position of the body (12) relative to the combination seat (1 1 2) is provided with two arc-shaped guide perforations (1 1 3) 'corresponding to each other, and a penetration is provided at a position different from the combination seat (11 2) Aperture hole (114). The driving device (1 2) is a device mounted on the combining base (1 1 2) and includes a motor (121), an interface device (122), and a horizontal driving rod (123). The motor (121) may be a stepping motor or It is a more conventional motor that has a current sensor (1 2 5) composed of a Hall element (Hal 1 Element) to sense the change in the stator coil current in the motor (1 2 1), and an interface device (1 2 2 ) Is electrically connected to the motor (121), and the current sensor (125) is electrically connected to the device 1232999, so that the motor (1 2 1) can be controlled by a controller such as a servo through the interface device (1 2 2) At the same time, the controller controls the rotation. At the same time, the current sensor (2 5) can also measure the measured current value back to the controller through the interface device (丄 2 2) to reach the servo feedback control motor (1 2 1 ) Operation: The driving rod (123) can be rotated by the motor (12 1) and has two coupling protrusions (124). The coupling protrusions (124) respectively face the corresponding guide holes (1 1 3). The adjusting device (1 3) is movably disposed in the accommodating space (1 1 1) of the main body 1), and includes two aperture plates (131) and two coupling sleeves (132) moving relative to each other. The sheet (131) has an overlapping portion (133) overlapping each other, a plurality of positioning guide holes (1 3 7) corresponding to the positioning protrusions (1 1 5), and a corresponding one of the guide perforations (1 1 3) long arm (1 3 4); each stack θ (1 3 3) is provided with a <-shaped notch (1 3 5) opposite to each other, which can be changed by moving the relative position of the two aperture plates (131) The aperture is adjusted by the size of the notch (丄 3 5) on the overlapping portion (1 3 3) to adjust the aperture; each long arm (1 3 4) is corresponding to the guide hole (1 丄 3) and is provided with a long guide hole (1 3 6). During assembly, each of the aperture plates (i 3 i) is partially overlapped in the accommodation space (1 work 1) of the body (11), and each positioning protrusion (115) is slidably accommodated in the corresponding space. In the positioning guide hole (i 3 7), at the same time, the area surrounded by the two notches (1 3 5) is aligned with the aperture hole (114), and the two coupling sleeves (1 3 2) respectively pass through the long guide hole (1 1232999 36), and can be slidably received and penetrated through the guide holes (113), and are 'combined with the coupling protrusions (124), thereby, when the motor (121) rotates the driving lever (123) clockwise or counterclockwise, , The respective diaphragms (1 3 1) can be pulled to generate relative movement, so that the area surrounded by the two notches (work 3 5) is enlarged or reduced. · The outer cover (1 4) is provided on the body (i i) to close the accommodation space (1 1 1), and has an outer perforation (1 4 1) arranged in line with the aperture hole (work 4).凊 Referring to the fourth figure, when the motor (丄 2 i) rotates the driving lever (123) clockwise, the driving lever (123) pulls the diaphragm (13 1) to cause relative movement to make two notches (135) on it.

Please refer to the fifth figure, when the motor (i 2 i) rotates the driving lever (123) counterclockwise, the driving lever (123) pulls the diaphragm (13 1) to cause relative movement to cause two notches (135) on it. Move towards each other, at this time, the area surrounded by the two notches (135) will gradually decrease, reducing the amount of light entering by the camera. Since the rotation speed and angular displacement of the motor (1 2 1) can be precisely controlled and continuously output by the servo controller, the relative movement of the aperture plate (131) is caused to cause two notches on it (135) Moving towards or away from each other can accurately control and change the area surrounded by the two notches (1 3 5), so as to optimize the amount of light entering by the camera, and improve the quality of photography. 1232999 The technical means of the present invention disclosed above is only used to explain the preferred implementation state of the present invention, but it does not mean that the implementation mode of the present invention is limited to the above disclosed preferred embodiments.
