Description

Camera device

Technical Field

The present invention relates to a camera device, and more particularly, to a camera device capable of performing count display.

Background

Conventionally, a camera using a photo film that can be automatically developed after shooting, that is, a so-called instant camera, has been known. Such an instant camera can be loaded with a photo film cassette that accommodates a plurality of photo films (for example, see patent document 1). Since the number of photo films stored in the photo film cassette is determined, the photographer needs to be notified of the remaining number of photo films, the camera disclosed in patent document 1 counts the number of discharged photo films, and displays the remaining number of photo films on the LCD panel.

However, since such an LCD panel is expensive, manufacturing costs of the camera increase due to the additional LCD panel. In addition, since a space for disposing a circuit board and wiring associated with the LCD panel needs to be secured in the camera, it is difficult to miniaturize the camera. Therefore, it is required to realize a count display of the number of remaining photo films or the like in a low-cost and compact structure.

The front end of the engaging portion 73 on the-Z direction side has a pointed shape.

Fig. 6A is a front view of the slider 50, fig. 6B is a left side view, fig. 6C is a right side view, and fig. 6D is a rear view. As shown in fig. 6A to 6D, the slider 50 has a slider body 52 accommodated in the guide groove 25 of the door member 20 and a plurality of hooks 54 protruding from the slider body 52 in the-X direction. A plurality of concave portions 53 recessed in the-Z direction are formed in the slider body 52. The plurality of hooks 54 are formed in a line along the Y direction, and the plurality of recesses 53 are also formed in a line along the Y direction. In the present embodiment, the Y-direction pitch P1 (see fig. 6C) of the adjacent concave portions 53 is the same as the Y-direction pitch P2 (see fig. 6D) of the adjacent hook portions 54. A display 56 indicating the number of remaining photographic films F in the film cassette 30 is formed on a surface 59 (display surface) on the-Z direction side of the slider body 52. In the present embodiment, as such a display 56, embossing of characters representing "S" and numerals from "10" to "0" are formed in order in the-Y direction. Such a display 56 need not be embossed, but may be printed or decal.

Fig. 7 is a partially enlarged front view showing a state in which the cover 42 of the display 40 is detached. In fig. 7 and the following, the coil spring 41 is shown simplified. As described above, the coil spring 41 is stretched between the pin 51 formed on the slider 50 and the pin 26 formed at the end of the guide groove 25. Accordingly, the slider 50 is biased in the-Y direction by the biasing force of the coil spring 41. A restricting pin 29 is formed in the vicinity of the pin 26 in the guide groove 25, and the movement of the slider 50 in the-Y direction is restricted by the lower edge of the slider 50 abutting against the restricting pin 29.

Fig. 8 is an enlarged partial cross-sectional view of door member 20 including display 40. In the state shown in fig. 8, the engaging portion 73 of the stopper member 70 is pressed toward the-Z direction by the rear side frame 32 of the film cassette 30, whereby the engaging portion 73 of the stopper member 70 engages with 1 recess 53 of the plurality of recesses 53 of the slider 50. In the example shown in fig. 8, the engagement portion 73 of the stopper member 70 is engaged with the recess 53A located at the most upper position.

Fig. 9 is a partially enlarged rear view showing a part of the camera apparatus 1 including the display 40. As shown in fig. 4 and 9, a rectangular frame member 12 accommodating the film cassette 30 is accommodated in a case formed by the front cover 2, the rear cover 3, the top cover 4, the battery cover 6, and the door member 20. The frame member 12 is provided with a driving unit 80 for moving the slider 50 in the +y direction.

The driving unit 80 includes: a drive lever 83 including a shaft portion 81 and an arm portion 82, the shaft portion 81 being disposed around the shaft 13 provided to the frame member 12, the arm portion 82 extending from the shaft portion 81; and a torsion coil spring 85 disposed around the shaft 13. The torsion coil spring 85 biases the driving lever 83 in the +x direction, presses the driving lever 83 against the inner wall 18 of the frame member 12, and biases the driving lever 83 in the counterclockwise direction when viewed along the X axis direction. The rotation of the drive lever 83 is regulated by abutting against a regulating pin 19 formed on the inner wall 18 of the frame member 12. The drive lever 83 is configured to be rotatable about the shaft 13 of the frame member 12 while receiving the urging force from the torsion coil spring 85. In the state shown in fig. 9, the arm 82 of the driving lever 83 does not engage with the hook 54 of the slider 50, but as described later, the arm 82 of the driving lever 83 engages with the hook 54 of the slider 50 by the driving lever 83 rotating around the shaft 13.

The frame member 12 is mounted with a movable member 14 that moves in the Y direction by a driving mechanism, not shown. As shown in fig. 4, the movable member 14 has a hook 15 engageable with the edge of the photographic film F after shooting, and the movable member 14 is moved in the +y direction in a state in which the lower edge of the film used for shooting is engaged with the hook 15, whereby the photographic film F is moved in the +y direction, and the photographic film is discharged from the discharge slit 4A (see fig. 1) of the top cover 4.

Fig. 9 shows a state in which a new film cassette 30 has just been loaded into the interior of the housing of the camera apparatus 1. In this state, the display 56A of "S" of the slider 50 is located on the +z direction side of the window 21 of the door member 20. The display 56A of "S" means that the loaded film cassette 30 is not used, and the user using the camera apparatus 1 can know that the loaded film cassette 30 is not used through the display 56A of "S" seen from the window 21 of the door member 20.

Fig. 10 is a left side view schematically showing the relationship of the slider 50, the driving portion 80, and the movable member 14. As shown in fig. 10, the movable member 14 includes the push rod 16 positioned below the driving lever 83 of the driving unit 80, and when the movable member 14 is moved in the +y direction by the driving mechanism as described above, the push rod 16 contacts the arm 82 of the driving lever 83 and rotates the driving lever 83 clockwise in fig. 10 about the shaft 13.

As described above, in the state shown in fig. 9, the new film cassette 30 is just loaded, but in order to take a picture from this state, the user first presses the release button 9 to start the shooting operation. Since the first photo film in the film cassette 30 is not a photo film for shooting but a film for exposure prevention, shooting is not performed by this shooting operation, but after the shooting operation, the movable member 14 is moved in the +y direction by the driving mechanism in the same manner as in the normal shooting. At this time, the hook 15 of the movable member 14 engages with the lower edge of the exposure preventing film, and therefore, the exposure preventing film is fed in the +y direction and finally discharged from the discharge slit 4A of the top cover 4, and the next photo film in the film cassette 30, that is, the 1 st photo film, is set at the position where exposure is possible.

In the middle of the delivery of the exposure preventing film, the push rod 16 of the frame member 12 hits the arm 82 of the drive rod 83, and rotates the drive rod 83. As shown in fig. 11 (during film feeding), by the rotation of the driving lever 83, the arm 82 of the driving lever 83 engages with the hook 54 of the slider 50, and the slider 50 can be moved in the +y direction against the urging force of the coil spring 41.

When the slider 50 moves in the +y direction, the engagement portion 73 of the stopper member 70 (see fig. 12 (at rest)) engaged with the recess 53A of the slider 50 is pressed in the +z direction by the ridge portion 57 adjacent to the recess 53A. As described above, the engaging portion 73 of the stopper member 70 is pressed in the-Z direction by the rear side frame 32 of the film cassette 30, and the pressing force of the rear side frame 32 is smaller than the force received from the ridge portion 57 of the slider 50 when the stopper member 70 moves in the +y direction, so that the engaging portion 73 of the stopper member 70 can be moved in the +z direction along the ridge portion 57 and simultaneously the slider 50 can be moved in the +y direction.

When the movement of the slider 50 in the +y direction is completed due to the rotation of the drive lever 83, as shown in fig. 12 (during film feeding), since the engagement portion 73 of the stopper member 70 is located on the inclined surface of the recess 53B adjacent to the recess 53A, after the engagement between the arm 82 of the drive lever 83 and the hook 54 of the slider 50 is released, the engagement portion 73 of the stopper member 70 moves in the-Z direction along the inclined surface by the pressing force from the rear side frame 32 of the film cassette 30, and accordingly, the slider 50 moves in the +y direction.

As described above, by the movement of the movable member 14 in the +y direction after the shooting operation, the engagement portion 73 of the stopper member 70 moves from the recess 53A to the adjacent recess 53B by the distance P1 (=p2), and the slider 50 is held at this position by the engagement of the engagement portion 73 of the stopper member 70 with the recess 53B (see (film feeding completed) of fig. 12). At this time, as shown in fig. 11 (film feeding completed), the display 56B of "10" of the slider 50 is located on the +z direction side of the window 21 of the door member 20. The display 56B of "10" indicates the number of remaining photo films F in the film cassette 30. Therefore, the user using the camera apparatus 1 can learn from the display 56B of "10" seen from the window 21 of the door part 20 that 10 photos are taken thereafter.

When the user presses the release button 9 in this state, the shooting operation is started, and the 1 st photo film F is exposed to be shot. After the shooting operation, the movable member 14 is moved in the +y direction as described above, and accordingly, the slider 50 is moved in the +y direction by the distance P1 (=p2), and "9" which is the number of remaining photo films F in the film cassette 30 is displayed on the window 21 of the door member 20.

After that, similarly, each time the shooting operation is completed, the slider 50 is moved in the +y direction by the distance P1 (=p2), and the remaining number of photo films F in the film cassette 30 is displayed on the window 21 of the door member 20.

As described above, according to the present embodiment, the arm 82 of the drive lever 83 engages with the hook 54 of the slider 50, so that the slider 50 can be moved in the +y direction, and after the slider 50 is moved, the engagement portion 73 of the stopper member 70 engages with the recess 53 of the slider 50, so that the slider 50 can be held at that position. Therefore, by operating the driving lever 83 at a desired timing, the display seen from the window 21 of the door member 20 can be changed. Thus, a high-priced component such as an LCD panel or a circuit board is not required, and a desired count display can be realized in an inexpensive and compact structure.

For example, when all of the photo films F in the film cassette 30 are used up, the film cassette 30 is replaced with a new one, but in this case, as shown in fig. 4, the door member 20 is opened and the film cassette 30 is replaced with a new one. As shown in fig. 4, when the door member 20 is opened, the rear frame 32 of the film cassette 30 that presses the stopper member 70 of the display 40 toward the-Z direction before that is separated from the stopper member 70, and therefore the stopper member 70 of the display 40 cannot be kept in the engaged state with the recess 53 of the slider 50, and the slider 50 is moved from the initial state shown in fig. 7 and 9 (the state in which "S" can be seen from the window 21) by the urging force of the coil spring 41. Therefore, in a state where the new film cassette 30 is just loaded, the state where "S" can be seen from the window 21 is defined.

In addition, when the door member 20 is opened, a biasing member (torsion coil spring, leaf spring, or the like) that biases the stopper member 70 away from the slider 50 may be disposed so that the engagement state of the stopper member 70 with the recess 53 of the slider 50 is easily released.

In the above-described embodiment, the display 40 is provided to the door member 20, but the display 40 may be provided to another member constituting the housing of the camera device 1, for example, the rear cover 3. In the above embodiment, the display 40 displays the remaining number of the photo films F in the film cassette 30, but the display 40 may be used to display a count other than the remaining number of the photo films F. Therefore, in such a case, the camera apparatus 1 does not need to include the door member 20 and the film cassette 30.

As described above, according to one embodiment of the present invention, a camera device capable of realizing a desired count display in an inexpensive and compact structure is provided. Specifically, the camera device of the present invention can have the following configuration.
