[0002] A camera, also called a photographing machine, is an optical device that uses the principle of optical imaging to form an image and records the image using negative film. Cameras can be roughly divided into film cameras and digital cameras according to the difference in imaging media. With the development of society and the progress of technology, traditional film cameras have faded out of people's sight because the clarity of their imaging is inferior to that of digital cameras, and people generally use digital cameras or directly use mobile phones to take pictures. However, film cameras have consistently and firmly remained in people's minds due to their unique operating method. Summary of the Invention [Problem to be solved by the invention]

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned attached drawings are intended to distinguish different objects and are not intended to describe a specific order.

[0020] An "embodiment" referred to in this application means that a combination of specific features, structures, or characteristics described in the embodiment can be included in at least one embodiment of this application. The appearance of the short phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it refer to an embodiment that is mutually exclusive, independent, or preliminary to other embodiments. As a person skilled in the art would clearly and implicitly understand, the embodiments described in this application can be mutually combined with other embodiments.

[0021] In order to make those skilled in the art better understand the present application, the following clearly and completely describes the technical solutions in the embodiments of the present application based on the accompanying drawings.

[0022] 1 to 7, the camera includes a housing 1, which includes a front housing 101 and a rear housing 102, which are fixedly connected by screws, and a cavity is formed in the front housing 101 and the rear housing 102 for mounting other members. The front housing 101 and the rear housing 102 of the housing 1 are installed in a detachable manner, which not only makes it easy to assemble but also makes it easy to remove for maintenance. A strap hole 103 is provided on one side of the housing 1, and a strap can be inserted through the strap hole 103, which makes it convenient to carry the camera when going out.

[0023] A control plate 2 and a lens 3 are attached in a cavity of a housing 1, the lens 3 is electrically connected to the control plate 2, one end of the lens 3 extends from the front end surface of the housing 1, a contact switch 4 is installed on the control plate 2, a rolling dial mechanism 5 is provided in the housing 1, one end of the rolling dial mechanism 5 extends from the upper end surface of the housing 1, and the rolling dial mechanism 5 can contact the contact switch 4. When taking an image, a user operates the rolling dial mechanism 5 to bring it into contact with the contact switch 4, thereby making the contact switch 4 conductive, and at that time, the control plate 2 controls the lens 3 to take an image, thereby realizing the image. Since the imaging principle of the camera can adopt the imaging principle of existing digital cameras, the specific structure and imaging principle will not be described in detail again in this specification.

[0024] Specifically, the rolling dial mechanism 5 includes a rolling dial support frame 51, which is fixedly mounted within the housing 1, and a rolling dial 52, a shutter button 53 and an interlocking member 54 are provided on the rolling dial support frame 51, the rolling dial 52 is rotatably connected to the rolling dial support frame 51, one side of the rolling dial 52 extends from the rear end surface of the housing 1, the shutter button 53 is connected to the rolling dial support frame 51 so as to be movable and have its position limited, and one end of the shutter button 53 extends from the upper end surface of the housing 1, and the interlocking member 54 is connected to the rolling dial support frame 51 so as to be movable and have its position limited. When capturing an image, the user presses the shutter button 53 to move the interlocking material 54, which then descends and contacts the contact switch 4 to turn on the contact switch 4. The contact switch 4 feeds back a signal to the control plate 2, and after receiving the on signal, the control plate 2 controls the lens 3 to capture an image, completing the imaging operation.

[0025] In order to restore the same feeling as the operation of a film camera, in this embodiment, a position limiting boss 521 is provided on the lower end surface of the rolling dial 52, a position limiting notch 522 is provided on the position limiting boss 521, and a position limiting rolling block 541 is provided on the interlocking member 54, the position limiting rolling block 541 is slidably fitted into the position limiting boss 521, and the position limiting rolling block 541 can be locked and connected to the position limiting notch 522. An elastic position limiting member 55 is provided on the rolling dial support frame 51, and a position limiting tooth 523 is provided on the outer wall of the rolling dial 52, and one end of the elastic position limiting member 55 is slidably and locked and connected to the position limiting tooth 523. When the rolling dial 52 rotates, the elastic position limiting member 55 slides on the position limiting tooth 523, and the position limiting rolling block 541 slides on the position limiting boss 521.

[0026] In the initial state, the position limiting rolling block 541 abuts against the position limiting boss 521, and the user can rotate the rolling dial 52 to slide the elastic position limiting member 55 on the position limiting tooth 523. The elastic position limiting member 55 generates elastic deformation and sequentially engages with each position limiting tooth 523, emitting a "clack" sound. After the rolling dial 52 rotates and the position limiting notch 522 and the position limiting rolling block 541 are aligned, the position limiting rolling block 541 enters the position limiting notch 522 and engages with it, emitting a mechanical collision sound. At this time, the rolling dial 52 rotates and the position limiting notch 522 and the position limiting rolling block 541 are aligned, and then the position limiting rolling block 541 enters the position limiting notch 522 and engages with it, emitting a mechanical collision sound. The dial 52 cannot continue to rotate, and then the user can press the shutter button 53, which causes the interlocking member 54 to move downward, causing the position limiting rolling block 541 to detach from the position limiting notch 522 and abut against the position limiting boss 521 again. Only after the position limiting rolling block 541 has detached from the position limiting notch 522 can the rolling dial 52 continue to rotate, and at the same time, during the downward movement of the interlocking member 54, it comes into contact with the contact switch 4 to emit an imaging signal, and the control plate 2 controls the lens 3 to capture an image, thereby completing a series of imaging operations.

[0027] This camera adopts the imaging principle of a digital camera, so that the user can obtain photos with high clarity; at the same time, the cooperation of the rolling dial 52, the interlocking member 54 and the elastic position limiting member 55 allows the user to experience the same feeling as operating a film camera; the user can hear the "click-click" sound by turning the rolling dial 52, and only after pressing the shutter button 53 can the rolling dial 52 be turned again, which satisfies the user's nostalgia and increases the user's favorable impression in terms of use.

[0028] In this embodiment, the position limiting boss 521 has a spiral ring structure, a position limiting groove 524 is provided in the position limiting boss 521, and a guide column 543 is provided at one end of the position limiting rolling block 541. The guide column 543 extends into the position limiting groove 524 and is slidably fitted into the inner wall of the position limiting groove 524. In the process of rotating the rolling dial 52, the guide column 543 slides on the inner wall of the position limiting groove 524. The fitting between the guide column 543 and the position limiting groove 524 can, on the one hand, prevent the interlocking member 54 from detaching from the rolling dial 52 and increase the stability of the structure; and on the other hand, the guide column 543 slides along the inner wall of the position limiting groove 524, thereby providing a torsion to the interlocking member 54, allowing the interlocking member 54 to rotate.

[0029] In order to reset the interlocking member 54, a torsion spring 56 is fitted in the interlocking member 54, and a rotation position limiting block 542 is provided on the interlocking member 54, one end of the torsion spring 56 abuts against the rotation position limiting block 542, and the other end is connected to the rolling dial support frame 51, the rotation position limiting block 542 can abut against the side wall of the rolling dial support frame 51, and the torsion spring 56 can drive the lifting and rotating movement of the interlocking member 54. When the rolling dial 52 is rotated, the position limiting rolling block 541 slides on the position limiting boss 521, the guide column 543 slides along the inner wall of the position limiting groove 524, and the interlocking member 54 rotates in response to this, and at the same time presses the torsion spring 56. After the rolling dial 52 rotates to the limit position, the position limiting rolling block 541 engages in the position limiting notch 522, and the user can press the shutter button 53 to realize image capture. In the process of the user pressing the shutter button 53, the shutter button 53 pushes the interlocking member 54 downward, compressing the torsion spring 56, and the position limiting rolling block 541 is driven by the interlocking member 54 to leave the position limiting notch 522. Then, under the elastic action of the torsion spring 56, the rotation position limiting block 542 abuts against the rolling dial support frame 51, causing a collision and producing a "clack" sound. At this time, the position limiting rolling block 541 exceeds the position limiting boss 521. After the user releases the shutter button 53, under the elastic action of the torsion spring 56, the interlocking member 54 is pushed upward until the position limiting rolling block 541 abuts against the position limiting boss 521, and then the user can continue to rotate the rolling dial 52 to slide the position limiting rolling block 541 on the position limiting boss 521. The torsion spring 56 can provide the linking member 54 with driving forces in two directions, rotation and lift, so that the linking member 54 can jump out of the position limiting notch 522 and abut against the position limiting boss 521 .

[0030] The height of the position limiting boss 521 gradually increases along the rotation direction of the rolling dial 52. When the user presses the shutter button 53, the position limiting rolling block 541 leaves the position limiting notch 522, and then the interlocking member 54 is driven to rotate under the elastic action of the torsion spring 56. After the interlocking member 54 passes the position limiting notch 522, the position limiting rolling block 541 abuts against the lowest end of the position limiting boss 521. As the rolling dial 52 rotates, the position limiting boss 521 abutting against the position limiting rolling block 541 gradually rises, appropriately pressing the position limiting rolling block 541 and compressing the torsion spring 56. In this way, the force with which the user rotates the rolling dial 52 must also be appropriately increased, and therefore the user's feeling when rotating the rolling dial 52 can be improved.

[0031] In order to reset the shutter button 53, a reset spring 57 is provided on the shutter mounting frame, one end of the reset spring 57 is connected to the shutter button 53, and the other end is connected to the rolling dial support frame 51, and the reset spring 57 is used to drive the upward movement of the shutter button 53. In order to limit the position of the shutter button 53, a position limit latch 531 is provided on the shutter button 53, which passes through the rolling dial support frame 51 and can abut against the lower end surface of the rolling dial support frame 51. When the user presses the shutter button 53, the shutter button 53 compresses the reset spring 57, and the position limit latch 531 extends from the lower end surface of the rolling dial support frame 51. After the user releases the shutter button 53, under the elastic action of the reset spring, the shutter button 53 is pushed and moves upward, and the position limit latch 531 moves together with the shutter button 53 until the position limit latch 531 abuts against the lower end surface of the rolling dial support frame 51.

[0032] In this embodiment, the contact switch 4 includes a contact plate 41 and an elastic plate 42, the contact plate 41 and the elastic plate 42 are respectively welded to the control plate 2, a gap is reserved between the elastic plate 42 and the contact plate 41, one end of the interlocking member 54 extends from the rolling dial support frame 51 and can contact the elastic plate 42, and the interlocking member 54 can be pushed so that the elastic plate 42 deforms in a direction approaching the contact plate 41. In normal cases, the contact plate 41 and the elastic plate 42 are separated from each other and are not electrically connected to each other. After the user presses the shutter button 53, the shutter button 53 pushes the interlocking member 54 to move downward, and the other end of the interlocking member 54 extends from the rolling dial support frame 51 to contact the elastic plate 42. As the interlocking member 54 continues to move downward, the interlocking member 54 pushes the elastic plate 42 to generate elastic deformation until the elastic plate 42 contacts the contact plate 41 and the two are conductive, and then feeds back a signal to the control plate 2. After the control plate 2 receives the conductive signal, it controls the lens 3 to capture an image, and the image capture is completed. After the user releases the shutter button 53, the interlocking member 54 returns upward under the action of the torsion spring 56, and at this time, the elastic plate 42 automatically returns under its own elastic action, separates from the contact plate 41, and returns to its initial position.

[0033] A battery case 104 is installed in the housing 1, and the battery case 104 is electrically connected to the control plate 2. The battery case 104 is for accommodating a battery and supplies power to the control plate 2 to realize an imaging function. A battery cover 105 is attached to the battery case 104 and is detachably connected to the housing 1. When the battery cover 105 is opened, the battery case 104 is exposed and the battery in the battery case 104 can be removed. The battery cover 105 simplifies battery replacement, improving practicality.

[0034] In order to easily capture images even in places where the light is dark, a flash lamp 6 is attached to the housing 1, one end of the flash lamp 6 extends from the front end surface of the housing 1, and the flash lamp 6 is used to supplement light when the user captures images. Since the flash lamp 6 requires a relatively large voltage and current, it must first be charged before it can be used. In this embodiment, a flash charging switch 61 and a charging indicator lamp 62 are provided on the housing 1, and a circuit structure for charging the flash lamp 6 is provided on the control plate 2, and the flash lamp 6, the flash charging switch 61, and the charging indicator lamp 62 are electrically connected to the control plate 2. When it is necessary to use the flash lamp 6, the user must first press the flash charging switch 61, and at that time, the battery is charged in the flash lamp 6 through the charging circuit, and the charging indicator lamp 62 is turned on, and when the charging indicator lamp 62 is turned off, it means that charging has already been completed. After that, after the user presses the shutter button 53, the control plate 2 controls the lens 3 to capture images and simultaneously controls the flash lamp 6 to operate, and the flash lamp 6 is turned on to supplement light for capturing images.

[0035] When the ambient light is sufficient, there is no need to press the flash charging switch 61, and the flash lamp 6 will not work when the user takes a picture. This design can effectively save the battery power and extend the battery life.
