Description

Camera device

Technical Field

The present invention relates to a camera device, and more particularly, to a camera device using a photographic film that can be automatically developed after shooting.

Background

Conventionally, a camera (i.e., a developing camera) is known which discharges a developed photo film to the outside using a photo film which can be automatically developed after photographing (for example, see patent document 1). In such a camera body frame, an opening may be formed due to manufacturing constraints. When light enters from the outside through such an opening, the photographic film is exposed, and therefore a light blocking member that closes the opening is attached to the main body frame. Generally, such a light shielding member is attached to a main body frame by a simple method (snap-fit) by engaging a hook portion provided on the light shielding member with a projection formed on the main body frame.

In recent years, with the progress of multifunction of cameras, there has been an increasing need to mount components for realizing additional functions also on such a light shielding member. In order to attach the additional member to the light shielding member, it is necessary to firmly fix the light shielding member itself to the main frame, but in the snap-fit, the attachment strength of the light shielding member to the main frame may be insufficient, and a structure capable of improving the attachment strength of the light shielding member at low cost is required.

Detailed Description

Hereinafter, an embodiment of a camera device according to the present invention will be described in detail with reference to fig. 1 to 5. In fig. 1 to 5, the same or corresponding components are denoted by the same reference numerals, and overlapping description thereof is omitted. In fig. 1 to 5, the scale and size of each component may be exaggerated, and some components may be omitted. In the following description, unless otherwise specified, terms such as "first" and "second" are used merely to distinguish constituent elements from each other, and do not indicate a specific order or sequence.

Fig. 1 is a perspective view showing a camera device 1 according to an embodiment of the present invention. The camera device 1 in the present embodiment is a camera (i.e., a display camera) using a photographic film which is automatically developed after photographing, but the present invention can be applied to a camera other than such a display camera. In the present embodiment, for convenience, the + X direction in fig. 1 is referred to as "front" or "front", and the-X direction is referred to as "rear" or "rear".

As shown in fig. 1, the camera apparatus 1 has a front cover 2, a rear cover 3 mounted behind the front cover 2, and a top cover 4 sandwiched by the front cover 2 and the rear cover 3. A finder window 5 is formed in the front cover 2, and a flash portion 6 is disposed adjacent to the finder window 5. Further, a release button 7 is disposed on the-Z direction side of the finder window 5. Light receiving windows 9A and 9B are disposed near the + Y direction end of the front cover 2. A discharge slit 4A extending in the Y direction is formed in the top cover 4, and a photographic film developed after photographing is discharged from the discharge slit 4A.

The camera device 1 further includes a lens barrel 10 housed inside the cylindrical portion 2A of the front cover 2. The lens barrel 10 in the present embodiment has a structure that can be extended in the + X direction. Fig. 2 is a perspective view showing the lens barrel 10 in a state of being maximally extended in the + X direction. As shown in fig. 2, the lens barrel 10 includes a first cylinder 11, a second cylinder 12, and a third cylinder 13. The first cylindrical portion 11 is movable in the X direction with respect to the cylinder portion 22 of the main body frame 20, and the second cylindrical portion 12 is movable in the X direction with respect to the first cylindrical portion 11. The third tubular portion 13 is movable in the X direction relative to the second tubular portion 12.

Fig. 3 is a perspective view showing a part of the components housed between the front cover 2 and the rear cover 3. As shown in fig. 3, the camera apparatus 1 has a main body frame 20 on which various components are mounted. The main body frame 20 includes a substantially rectangular parallelepiped base portion 21 and a cylindrical barrel portion 22 extending forward from the base portion 21 and holding the lens barrel 10. The circuit board 30 is disposed in front of the base portion 21 of the main body frame 20.

Returning to fig. 2, 2 engaging projections 14 projecting outward in the radial direction are formed at the rear end portion of the first barrel portion 11 of the lens barrel 10. As shown in fig. 3, 2 guide grooves 24 extending in the direction of the optical axis (X direction) are formed in the cylinder section 22 of the main body frame 20 corresponding to the respective engaging projections 14. Each of the engaging projections 14 of the lens barrel 10 is housed inside a guide groove 24 of the barrel portion 22, and engages with the guide groove 24. The width of the guide groove 24 in the Z direction is slightly larger than the width of the engaging projection 14 in the Z direction. Therefore, the engaging projection 14 moves in the X direction inside the guide groove 24 while being guided by the guide groove 24.

As shown in fig. 3, the operation button 8 is provided in the vicinity of the cylinder section 22 of the main body frame 20 in a state of being biased in the + X direction by the coil spring 8A. As shown in fig. 1, the operation button 8 protrudes from the front cover 2 in the + X direction in the vicinity of the cylindrical portion 2A of the front cover 2, and the user can press the operation button 8 in the-X direction.

A barrel extension mechanism Q is attached to the barrel section 22, and includes: a lever 8B which is interlocked with the operation button 8 to push out the engagement projection 14 in the + X direction; and a torsion coil spring (not shown) whose direction of urging the engaging projection 14 is reversed according to the position of the engaging projection 14. The torsion coil spring is configured to urge the engagement projection 14 in the + X direction when the engagement projection 14 moves in the + X direction beyond a predetermined position, and to urge the engagement projection 14 in the-X direction when the engagement projection 14 moves in the-X direction beyond a predetermined position. The barrel extension mechanism Q is not limited to a specific configuration, and may have any configuration as long as the lens barrel 10 can be extended in the + X direction.

Therefore, when the user presses the operation button 8 in the-X direction, the engagement projection 14 of the lens barrel 10 is pushed out in the + X direction by the lever 8B of the barrel extension mechanism Q, and the lens barrel 10 is extended in the + X direction (extending direction). When the lens barrel 10 is ejected from the barrel 22 in the + X direction, the power supply of the camera device 1 is turned on by a not-shown switching mechanism.

Fig. 4 is a longitudinal sectional view showing a part of the camera apparatus 1, and fig. 4 omits illustration of the front cover 2 and the lens barrel 10. As shown in fig. 4, a film housing space S for housing a photographic film (not shown) containing a developer solution therein is formed inside the base portion 21 of the main body frame 20. An openable and closable door member 90 is attached to the back cover 3, and by opening and closing the door member 90, the film storage space S can be accessed to take out and put in photographic film (not shown).

Above the film storage space S, 1 pair of rollers 92A and 92B are provided. A torsion coil spring 94 is disposed behind the roller 92B, and the torsion coil spring 94 is configured to urge the roller 92B in the + X direction via a pressing member (not shown). The discharge slit 4A of the top cover 4 is positioned above the rollers 92A and 92B, and a felt member 96 for the purpose of preventing foreign matter from entering and blocking light is disposed at the bottom of the discharge slit 4A.

The photographic film exposed by shooting is fed out from the film housing space S to between the 1 pair of rollers 92A and 92B by a feeding mechanism not shown. By pressing the photo film against these rollers 92A and 92B, the contained developer spreads in the photo film, and the developing process of the photo film is performed. The developed photo film passes between the felt members 96 and is discharged from the discharge slit 4A of the top cover 4 to the outside of the camera apparatus 1.

Fig. 5 is an exploded perspective view of the components shown in fig. 3. As shown in fig. 5, an opening P is formed in the front surface of the base portion 21 of the main body frame 20 due to molding constraints. When external light enters the film housing space S through the opening P, the photographic film is exposed to light, and a desired image cannot be obtained. In order to avoid exposure through the opening P, a light blocking member 40 for blocking the opening P is attached to the base portion 21.

As shown in fig. 3 and 5, the base portion 21 of the main body frame 20 has a claw portion 25 protruding from the side surface on the + Y direction side. The light blocking member 40 has a hook 41 engageable with the pawl 25 of the base 21. By engaging the hook portion 41 of the light blocking member 40 with the pawl portion 25 of the base portion 21, the light blocking member 40 can be attached to the base portion 21 by so-called snap-fit.

As shown in fig. 3 to 5, the circuit board 30 is disposed so as to cover the light shielding member 40. As shown in fig. 5, a screw hole 31 into which a screw 81 serving as a first fixing member is inserted is formed in the circuit board 30. The circuit board 30 is fixed to the main body frame 20 by inserting the screws 81 into the screw holes 31 of the circuit board 30 and screwing them into the screw holes of the fixing portion 26 formed in the barrel portion 22 of the main body frame 20.

Here, as shown in fig. 4 and 5, the light shielding member 40 has an abutment projection 42 that abuts the rear surface 30A of the circuit board 30. Since the contact projection 42 of the light shielding member 40 is in contact with the rear surface 30A of the circuit board 30, when the circuit board 30 is fixed to the main body frame 20 using the screw 81 as described above, the contact projection 42 of the light shielding member 40 is pressed in the-X direction by the rear surface 30A of the circuit board 30, and the light shielding member 40 is pressed and fixed to the base portion 21 of the main body frame 20.

That is, according to the present embodiment, when the circuit board 30 is fixed to the main body frame 20 by screwing the screw 81 into the screw hole of the fixing portion 26 of the main body frame 20, the abutment projection 42 of the light shielding member 40 abuts against the rear surface 30A of the circuit board 30 and is pressed against the base portion 21 side, thereby fixing the light shielding member 40. In this way, the light shielding member 40 can be fixed to the base portion 21 of the main body frame 20 not only by the engagement of the hook portion 41 of the light shielding member 40 with the pawl portion 25 of the base portion 21 but also by the abutment of the abutment projection 42 of the light shielding member 40 with the rear surface 30A of the circuit board 30, and therefore, the mounting strength of the light shielding member 40 to the main body frame 20 can be improved. Further, since the screws 81 for fixing the circuit board 30 to the main body frame 20 are used to press the light shielding member 40 against the main body frame 20, an additional fixing member is not required, and the manufacturing cost of the camera device 1 can be reduced.

As shown in fig. 3, the camera device 1 according to the present embodiment includes a sensor unit 50 as a first additional component, and the sensor unit 50 includes a sensor 51 for measuring the brightness around and the light amount emitted by the flash unit 6. These sensors 51 are configured to detect light incident through light receiving windows 9A and 9B (see fig. 1) provided in the front cover 2.

The sensor unit 50 is attached to the end of the light blocking member 40 on the + Y direction side. Specifically, the light blocking member 40 has fixing portions 43 and 44 formed with screw holes into which screws 83 and 84 as second fixing members are screwed, respectively, and the sensor unit 50 has mounting portions 53 and 54 into which the screws 83 and 84 are inserted, respectively. After the circuit board 30 and the light shielding member 40 are fixed to the main frame 20 by screwing the screws 81 into the screw holes of the fixing portion 26 of the main frame 20 as described above, the screws 83 and 84 are inserted into the screw holes of the mounting portions 53 and 54 of the sensor unit 50, respectively, and screwed into the screw holes of the fixing portions 43 and 44 of the light shielding member 40. Thereby, as shown in fig. 3, the sensor unit 50 is attached to the + Y direction side of the light shielding member 40. Further, although the sensor unit 50 is disposed with the central axis of the sensor 51 inclined downward, the sensor unit 50 can be attached to the side of the light blocking member 40 as in the present embodiment, thereby preventing the distal end of the lens barrel 10 from interfering with the measurement of the sensor 51.

In the present embodiment, as described above, the contact projection 42 of the light blocking member 40 is in contact with the rear surface 30A of the circuit board 30, whereby the strength of attachment of the light blocking member 40 to the main body frame 20 can be increased, and therefore, the light blocking member 40 can be prevented from coming off the main body frame 20 when the sensor unit 50 is attached to the light blocking member 40. In particular, if the fixing portion 44 to which the screw 84 is attached is disposed in the vicinity of the contact projection 42 as in the present embodiment, this effect is improved. In this way, an additional member such as the sensor unit 50 can be attached to the light shielding member 40, and thus, the camera device can be made multifunctional.

The camera device 1 in the present embodiment includes a flash unit 6 as a second additional component, and the flash unit 6 is disposed in front of the circuit board 30. The flash unit 6 has a mounting portion 65 into which a screw 85 as a third fixing member is inserted, and a screw hole 35 is formed in a portion of the circuit board 30 corresponding to the mounting portion 65. The light blocking member 40 has a mounting portion 45 through which the screw 85 is inserted. The screws 85 are inserted into the screw holes of the mounting portion 65 of the flash portion 6, the screw holes 35 of the circuit board 30, and the screw holes of the mounting portion 45 of the light shielding member 40 in this order, and are screwed into the screw holes of the fixing portion 27 formed in the base portion 21 of the main frame 20, whereby the flash portion 6 is fixed to the main frame 20 together with the circuit board 30 and the light shielding member 40.

In this way, when the flashing portion 6 is fixed to the base portion 21 of the main body frame 20 by the screw 85, the circuit board 30 and the light blocking member 40 are also fixed to the base portion 21 of the main body frame 20, and therefore, the attachment strength of the light blocking member 40 to the base portion 21 of the main body frame 20 can be further improved. Further, the camera device 1 is further increased in functionality by the flash unit 6 as an additional component.

In the above-described embodiment, the example in which the screw is used as the fixing member for fixing the component has been described, but such a fixing member is not limited to the screw, and any fixing member may be used instead of the screw.

The terms "front", "rear", "upper", "lower" and other terms indicating positional relationships used in the present specification are used in connection with the illustrated embodiments, and vary depending on the relative positional relationship of the devices.

As described above, according to one aspect of the present invention, there is provided a camera device capable of firmly attaching a light shielding member to a main body frame at low cost. The camera device includes a main body frame having a film housing space formed therein for housing a photographic film. An opening portion communicating with at least a part of the film housing space is formed on a front surface of the main body frame. The camera device includes: a light blocking member that closes the opening of the main body frame; a circuit board disposed in front of the main body frame so as to cover the light shielding member; and a first fixing member for fixing the circuit board to the main body frame. The main body frame has a claw portion protruding from a side surface. The light blocking member has a hook portion engageable with the claw portion of the main body frame and an abutting projection abutting against a rear surface of the circuit board.

According to such a configuration, when the circuit board is fixed to the main body frame by the first fixing member, the contact projection of the light shielding member comes into contact with the rear surface of the circuit board and is pressed against the main body frame side, thereby fixing the light shielding member. In this way, the light shielding member can be fixed to the main body frame not only by the engagement of the hook portion of the light shielding member with the pawl portion of the main body frame, but also by the abutment of the abutment projection of the light shielding member with the rear surface of the circuit board, and therefore, the attachment strength of the light shielding member to the main body frame can be improved. Further, since the first fixing member for fixing the circuit board to the main body frame is used to press the light shielding member against the main body frame, an additional fixing member is not required, and the manufacturing cost of the camera device can be reduced.

The camera device may further include: a first additional member disposed on a side of the light blocking member; and a second fixing member for fixing the first additional member to the light blocking member. As described above, since the mounting strength of the light shielding member to the main frame can be improved, the light shielding member can be prevented from coming off the main frame when the first additional member is mounted on the light shielding member. In this way, since the first additional member can be attached to the light shielding member, the camera device is promoted to be multifunctional.

The camera device may further include: a second additional member disposed in front of the circuit board; and a third fixing member that fixes the second additional member, the circuit board, and the light shielding member to the main body frame. In this case, when the second additional member is fixed to the main frame by the third fixing member, the circuit board and the light shielding member are also fixed to the main frame, and therefore, the mounting strength of the light shielding member to the main frame can be further improved. In addition, the second additional member further contributes to the multi-functionalization of the camera device.

While the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and may be implemented in various different forms within the scope of the technical idea thereof.
