Description

  The present invention relates to a camera case used by being attached to a camera such as a mobile phone with a camera.

Cameras, particularly digital cameras, are extremely popular due to their convenience. Such a camera captures an image by capturing image light with an imaging means such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS).
Most of the common cameras on the market are intended to capture people and landscapes, and it is not usually possible to perform high-magnification imaging such as using a microscope.

  However, since it is convenient if such an image can be taken, and there is a certain demand, the applicant of the present application has filed an application of Japanese Patent Application Laid-Open No. 2006-251113 in the past. This application discloses an attachment to be attached to a camera-equipped mobile phone having a camera as an example of a general camera. The attachment includes a main body portion attached to the camera and a lens portion that is detachable from the main body portion and includes a magnifying lens. This attachment allows high-magnification images to be taken using the magnifying lens included in the lens unit when the lens unit is attached to the main unit attached to the mobile phone. Alternatively, when the lens unit is removed from the main body unit, normal imaging that can be originally performed by a mobile phone camera can be performed.

This attachment has the effect of enabling a general camera to perform high-magnification imaging. In addition, when the main body is formed in the shape of a mobile phone case or jacket, the main body is left attached to the mobile phone, and the lens portion is attached to the main body only when high magnification imaging is required. In the case of mounting and performing normal imaging, it is possible to realize a usage mode in which the lens unit is detached from the main body, and there is an advantage that normal imaging and high-magnification imaging can be easily switched.
However, this attachment is not without its improvements.
As described above, the lens part in this attachment is removed from the main body part when high-magnification imaging is not performed, but how to perform the removed lens part tends to be a problem. is there. For example, it is possible to attach the removed lens part to the strap of the mobile phone, but it is a little inconvenient, and it cannot be denied that there is a problem in terms of beauty.

  The present invention has been made in view of the above points, and in a case where imaging at a high magnification is not performed for a camera case that enables imaging at a magnification higher than the magnification that the camera can originally capture. The objective is to improve the finish of the lens so that there is no difficulty in terms of convenience and aesthetics.

  The inventor of the present application proposes the following camera case in order to solve the above-described problems.

The camera case of the present invention is as follows.
That is, the camera case of the present invention is a camera case attached to a camera having a camera lens which is a lens exposed to the outside on a predetermined surface of the casing (the lens does not always need to be exposed). is there. The camera case includes a main body that is detachably fixed to the housing of the camera, and a lens holder that holds a magnifying lens for enlarging an image, and a predetermined position of the main body. A movable member that can be fixed between the first position and the second position, which is another predetermined position of the main body, and is movable so as to move the lens holder between the first position and the lens holder. A light source that is in the first position and is capable of assisting illumination when the camera captures an image as a magnified image according to the magnification of the magnifying lens; and a battery that supplies power to the light source. When the lens holder is in the first position, the magnifying lens is fixed on the optical path of the camera lens of the camera so that an image captured by the camera is captured. When the lens holder is in the second position so as to obtain an image according to the magnification of the magnifying lens, the image captured by the camera is left as it is by being out of the optical path of the camera lens. It is supposed to be.
In such a camera case, when the lens holder is located at the first position, the magnifying lens is located on the optical path of the camera lens of the camera. The magnification can be increased to a higher magnification that can be taken. Conversely, when the lens holder is in the second position, the camera can be used as it is without passing through the magnifying lens of the camera case. In this case, there is no need to remove the camera case from the mobile phone, and there is no need to remove the lens holder and the movable member from the camera case, so that there is no problem with the lens holder and the movable member. .
The camera according to the present invention does not necessarily have to be a main device for the camera, and may be any device including a camera such as a camera-equipped mobile phone with a camera.
The magnifying lens may be a single lens or a lens group composed of a plurality of lenses.

The battery supplies power to the light source as described above. The battery may also be adapted to be used as a backup power source for the camera.
For example, the main body includes a charging terminal for connecting the battery to a charging terminal of the camera when the main body is fixed to the camera, and the battery is used as a standby power source for the camera. It may be possible to use it.
By using it as a power source for the camera, it becomes possible to use the camera when the battery of the camera runs out, or to delay the battery running out of the camera. In particular, when the camera is a camera-equipped mobile phone, there is a tendency to use a battery as a standby power source for the camera (camera-equipped mobile phone) because there is a tendency to have a problem of battery capacity.

The light source of the present invention assists illumination when taking a high-magnification image with a camera. When a high-magnification image is captured, the imaging range becomes very narrow, and there is a tendency for insufficient illumination light per unit area. The light source assists illumination in that case. The light source may be configured to automatically irradiate illumination light when the lens holder comes to the second position. For example, the user may irradiate the light source with illumination light as necessary using a manual switch. It may be like this.
The light source may be provided anywhere in the camera case, but can be provided, for example, on a movable member or on a lens holder of the movable member.
The lens holder may be fixed to the movable member, but may be detachably attached to the movable member. In this case, the light source may be provided on the lens holder and emit illumination light suitable for the camera to take an image using a magnifying lens attached to the lens holder. Good.
When the lens holder is detachable with respect to the movable member, it is possible to pick up images at various magnifications with the camera by preparing several lens holders with different magnifications of the magnifying lens. Here, the necessary illumination changes depending on the magnification of the imaging. By providing a magnifying lens and a light source in the lens holder in advance as a set, a magnifying lens that determines the magnification of the imaging and illumination suitable for it are provided. This is convenient because the light source can be exchanged in a batch.

In the case where the light source is provided in a lens holder that is detachable from the movable member, and the battery is provided in the main body, the movable member is connected to the battery. And the lens holder is provided with a holder terminal connected to the light source, and when the lens holder is attached to the movable member, The battery may be used as a power source of the light source by connecting the movable member terminal and the holding body terminal to connect the battery and the light source. By doing so, it is convenient to connect the battery and the light source by exchanging the light source and the magnifying lens at once.
More specifically, one of the movable member and the lens holder is provided with a concave portion, and the other is provided with a convex portion that can be inserted into the concave portion, and the movable member among the concave portion and the convex portion. The movable member terminal is disposed on the inner side of the concave portion or on the outer side of the convex portion, and the concave portion of the concave portion and the convex portion provided on the lens holding body. The holding body terminals are respectively provided on the inner side or the outer side of the convex portion. By inserting the convex portion into the concave portion, the lens holding body is attached to the movable member, and the movable member terminal is provided. The holding body terminal may be electrically connected. By doing so, it is possible to reliably realize the connection between the battery and the light source in the case where the light source and the magnifying lens are exchanged in a batch while having a simple structure. In addition, the recessed part of this application includes the case where it is an annular shape without a bottom.

When the light source is provided in a lens holder that is detachable from the movable member, the battery is provided in the lens holder, and is detachable from the movable member together with the lens holder. It may be.
In this case, the battery is connected to the light source, and when the light source and the magnifying lens are exchanged at once, the battery provided on the lens holder is also exchanged at the same time.

  The lens holder may be hidden inside the main body when it is in the second position. If so, the lens holder can be hidden when the magnifying lens is not used, so that the aesthetics of the camera case can be enhanced and the possibility of damage to the lens holder can be reduced. .

There is no particular limitation on the shape and structure of the main body.
The camera in the present application may be a substantially rectangular parallelepiped mobile phone. The mobile phone in this case may be provided with a display on the front surface, an operation means for operating the mobile phone, and the camera lens on the back surface. In this case, the operation means and the display can be integrated by adopting, for example, a touch panel. Such shapes and structures are often used in touch-sensitive smartphones that have rapidly spread in recent years, for example, represented by iPhone (registered trademark) sold by Softbank Mobile Corporation.
When the camera is such a mobile phone, the main body has a substantially rectangular parallelepiped shape having a storage recess that is a recess that can store the mobile phone in the state where the front surface of the casing of the mobile phone is exposed. It can be a shape. With such a shape, not only the overall shape when the mobile phone is attached to the main body is clear, but also the mobile phone can be used while being stored in the main body, so Keeping the main unit attached to the mobile phone, coupled with the ability to capture the same image without using the magnifying lens with the camera and the image magnified using the magnifying lens. It is convenient because it becomes possible to do. The main unit can be left attached to the mobile phone, especially when the power of the mobile phone can be covered with a battery.
In this case, the main body can be further configured as follows. For example, the main body portion is one of a storage chamber having a predetermined thickness that has a substantially rectangular parallelepiped shape for storing the battery, and an outer surface of the storage chamber, and is in contact with the back surface of the casing of the mobile phone. It is assumed that all of the three sides of the circumference of the abutment surface are extended in a direction extending the thickness direction of the storage chamber, and the height substantially corresponds to the thickness of the casing. A bottom plate that is supposed to be in contact with the bottom surface of the housing, and two side plates that are intended to be in contact with the side surface of the housing, and the tip of the side plate Is provided with a locking portion bent in the center direction of the contact surface, the contact surface, the surface of the bottom plate facing the contact surface, and the two side plates. The storage recess formed as a space surrounded by a surface facing the abutment surface has two sides From between the plates, the rear surface of the casing of the mobile phone faces the contact surface, both side surfaces of the casing face the contact surfaces of the two side plates, and the front surface of the casing is the engagement surface. The mobile phone is slid while being brought into contact with the bottom surface of the stopper, and the bottom surface of the casing of the mobile phone is brought into contact with the surface of the bottom plate facing the contact surface. May be detachably fixed to the main body. If it carries out like this, fixation to a main-body part in the case where a mobile telephone is a substantially rectangular parallelepiped shape can be achieved easily.
Furthermore, when the charging terminal is provided on the bottom surface of the casing of the mobile phone, the camera case can be configured as follows. That is, the charging terminal is provided on a surface of the bottom plate facing the contact surface, and the bottom surface of the casing of the mobile phone is in contact with the surface of the bottom plate facing the contact surface. When in contact, the charging terminal and the charging terminal can be connected. In the present invention, the structure of the charging terminal is not particularly limited as long as it can be connected to the charging terminal of the mobile phone, but if such a charging terminal is adopted, the main body of the camera case for the mobile phone is used. It is convenient because the charging terminal and the charging terminal are also connected at the same time as the attachment to the battery. This configuration can be used only when the charging terminal is provided on the bottom surface of the casing of the mobile phone, but since many mobile phones adopt such a structure, the versatility is high to some extent.

It has come to be.
A space surrounded by the contact plate 21a, the two side plates 22, and the bottom plate 23 is a storage recess according to the present invention, and the mobile phone A is attached thereto.

The movable member 24 is a member configured to translate the notch 21 b in the vertical direction of the mobile phone A. The movable member 24 can be arbitrarily fixed at two positions, that is, an upper end position and a lower end position by adopting a known push-push structure, for example. The lens holder 3 is detachably attached to the movable member 24, and the lens holder 3 moves in the vertical direction as the movable member 24 moves. The movable member 24 in FIG. 3 is in a state of being moved up to the maximum, and the movable member 24 in FIG. 4 is in a state of being moved down in the maximum. The movable member 24 can be fixed at these two positions. As a result, the lens holder 3 is also fixed at the positions shown in FIGS. The case shown in FIG. 3 with the lens holder 3 at the top is the case in the first position referred to in the present invention, and the case shown in FIG. 4 with the lens holder 3 at the bottom is in the present invention. This is the case of the second position.
The camera hole 21c described above realizes the field of view of the lens D when the lens holder 3 is in the second position. The mobile phone A is attached to the camera case 1 and the lens holder 3 is provided. When the camera is in the second position, the camera built in the mobile phone A can perform normal imaging through only the lens D.

Although the movable member 24 is not necessarily limited to this, in this embodiment, the movable member 24 is a substantially rectangular parallelepiped body, the width of which is the width of the above-described notch portion 21b, and the thickness thereof is the thickness of the notch portion 21b. Are substantially corresponding to each. An opening (not shown) is provided on the upper surface of the movable member 24. This opening is used for connection between the lens holding body 3 and the movable member 24, and may be a hole with a bottom or a hole with a bottom. Inside the opening, there is provided a movable member terminal which is a terminal electrically connected to the battery 4 by a conducting wire (not shown).
A method for attaching the lens holder 3 to the movable member 24 will be described later.

Although the lens holder 3 is not necessarily limited to this, in this embodiment, the lens holder 3 has a substantially rectangular parallelepiped shape, the width of which corresponds to the width of the above-described notch 21b, and the thickness thereof substantially corresponds to the thickness of the notch 21b. It has been.

The cross-sectional shape of the rectangular portion below the circuit board 32 corresponds to the above-described cross-sectional shape of the opening provided in the movable member 24, and although not necessarily limited to this, it is a plate shape. A lens connection terminal 32 c is provided on the surface of the circuit board 32. By inserting the lower part of the circuit board 32 into the above-described opening provided in the movable member 24, the lens holder 3 can be detachably fixed to the movable member 24. When the lens holder 3 is fixed to the movable member 24, the lens connection terminal 32c and the movable member terminal in the opening are brought into conduction.
The magnifying lens cover 31 is a cylindrical body that has a front surface and a rear surface that are open and has a substantially rectangular parallelepiped shape.
The magnifying lens cover 31 and the circuit board 32 are essentially fixed as shown in FIG. 5, but any fixing method may be used. For example, if the magnifying lens cover 31 includes a locking hole and the circuit board 32 includes a cylindrical member that can be inserted into the locking hole, the cylindrical member is locked. What is necessary is just to fix both by inserting in a use hole. Of course, both may be fixed by fixing using screws, screws, bolts, nuts, etc., fixing using an adhesive, or the like.
The circuit board 32 is provided with a rectangular lens hole 32a. A magnifying lens 31a is fitted in the lens hole 32a. The magnifying lens 31a is a lens that magnifies an image. The lens hole 32a comes to a position corresponding to the camera hole 21c when the lens holder 3 is in the first position. Therefore, when the lens holder 3 is in the first position, the camera built in the mobile phone A can perform imaging at an enlarged magnification using the lens D and the magnifying lens 31a. .
The circuit board 32 includes a light source 32b around the magnifying lens 31a. The light source 32b irradiates a predetermined illumination light to the object to be imaged when imaging using the magnifying lens 31a. In this embodiment, the light source 32b is configured by nine LEDs surrounding the lens hole 32a. Yes. For the configuration of the light source 32b, for example, the shape, number, position, and the like thereof can be selected in accordance with the characteristics of the magnifying lens 31a. The light source 32b can be switched between illumination light for making a captured image a reflected image with surface reflection and illumination light for making a captured image a non-reflective image without surface reflection. In this embodiment, the illumination light can be selected by the reflection switch (not shown) of the main body 2. The light source 32b is connected to the lens connection terminal 32c by conduction not shown. When the lens holder 3 is fixed to the movable member 24, as described above, the lens connection terminal 32c and the movable member terminal in the opening are electrically connected. The light source 32b can be turned on using the battery 4 as a power source.
In this embodiment, the light source 32b is integrated with the lens connection terminal 32c. However, the present invention is not limited to this. For example, the magnifying lens cover 31 may include the light source 32b.

The battery 4 is provided inside the storage chamber 21. The battery 4 can be used as a power source for the light source 32b included in the camera-equipped mobile phone A and the lens holder 3. As described above, the battery 4 functions as a power source for the mobile phone A via the charging terminal B connected to the main body connection terminal 23a connected thereto, and the lens connected to the movable member terminal connected thereto. It functions as a power source for the light source 32b via the connection terminal 32c. Whether or not the battery 4 is used as the power source of the camera-equipped mobile phone A can be controlled by the power switch 21e of the main body 2. Whether or not the battery 4 is used as the power source of the light source 32b can be controlled by the light source switch 21d of the main body 2.
The battery 4 may be a general-purpose product or a dedicated product, a general primary battery, or a rechargeable secondary battery.
The battery 4 is exposed from the storage chamber 21 when the contact plate 21a is removed, and can be appropriately replaced in this state.
In this embodiment, the battery 4 is a single type dry battery, and is stored in the storage unit 41 which is a battery box having a shape in which four cylindrical bodies that are substantially rectangular parallelepipeds are arranged.

  Next, a method of using the camera case 1 will be described.

First, as shown in FIG. 5, the lens holder 3 is attached to the main body 2 via the movable member 24. When there are a plurality of magnifying lenses 31 a having different magnifications, the lens holding body 3 having a magnifying lens with a desired magnification is selected and attached to the movable member 24. This attachment is performed by inserting the rectangular portion below the circuit board 32 into the opening provided in the movable member 24.
Next, the camera-equipped mobile phone A is fixed to the camera case 1 as shown in FIG.
Such fixing is performed in a state in which the back surface of the casing A1 of the mobile phone A is brought into contact with the contact plate 21a and the both side surfaces of the case A1 are in contact with the opposing surfaces of the two side plates 22. This is done by translating A from the upper side of the camera case 1 downward. The bottom surface of the casing A1 of the mobile phone A is in contact with the bottom plate 23, and the convex body connection terminal 23a provided on the bottom plate 23 is inserted into the concave charging terminal B provided in the mobile phone A. Thus, the detachable fixing of the camera-equipped mobile phone A and the camera case 1 is completed. Since the locking portions 22a of the side plates 22 lock the front surface of the mobile phone A, the mobile phone A is prevented from dropping from the camera case 1.
At this time, since the front surface of the mobile phone A is exposed, the user can use the mobile phone A with the camera case 1 attached. The user also selects whether to use the battery 4 as the power source of the camera-equipped mobile phone A by the power switch 21e of the main body 2 as necessary. When it is selected that the battery 4 is used as the power source of the camera-equipped mobile phone A, power is supplied from the battery 4 to the mobile phone A via the main body connection terminal 23a and the charging terminal B.

In this state, the user moves the lens holder 3 to any position of the first position or the second position.
When the lens holder 3 is in the first position, the optical axes of the lens D and the magnifying lens 31a coincide. Thereby, the camera built in the mobile phone A can perform imaging at an enlarged high magnification by using the lens D and the magnifying lens 31a. At this time, the light source 32b can be turned on by operating the light source switch 21d of the casing A1 of the mobile phone A as necessary. When it is selected to turn on the light source 32b, power is supplied from the battery 4 to the light source 32b via the movable member terminal and the lens connection terminal 32c. When the light source 32b is turned on, illumination light suitable for imaging by the camera using the magnifying lens 31a is emitted.
On the other hand, when the lens holder 3 is in the second position, the magnifying lens 31a does not exist in front of the lens D, and the camera of the mobile phone A passes through the camera hole 21c at a normal magnification using only the lens D. Will be imaged. Normally, the light source 32b is not used for this imaging, so the light source switch 21d may be operated so that the light source 32b is not turned on. Note that a switch that automatically turns off the light source 32b when the lens holder 3 is moved from the first position to the second position can be provided in any part of the camera case 1. . By doing so, waste of the battery 4 can be prevented.

If necessary, the lens holder 3 attached to the movable member 24 can be exchanged even when the mobile phone A is fixed to the camera case 1.
When the camera case 1 is no longer needed, the operation reverse to that for the attachment is performed, and the mobile phone A is detached from the camera case 1.
Even when the camera case 1 is still attached, the mobile phone A can be used, for example, making a phone call or using the Internet.

<Modification>
In the camera case 1 described above, the battery 4 housed in the main body 2 supplies power to the light source 32b. Alternatively, it is possible to supply power to the light source 32b from another battery different from the battery 4. Another battery can be attached to the inside of the lens holder 3, for example. When the other battery is a small button battery or the like, it is sufficiently possible to store the other battery in the lens holder 3. In this case, the other battery can be always connected to the light source 32 b and can be attached to and detached from the movable member 24 together with the lens holder 3.
In the case of using another battery, it is not necessary to supply power from the battery 4 to the light source 32b, so that the movable member terminal and the lens connection terminal 32c are unnecessary.
Further, when using another battery, the battery 4 may be eliminated. In that case, since the space for storing the battery 4 is not necessary, the main body 2 can be made thinner accordingly.
In the case of using another battery, a switch for turning on / off the power supply from the other battery to the light source 32b can be provided on a lead wire connecting the light source 32b and the other battery.
