Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a camera in which a grip is detachable from the camera body, and in particular, various accessories such as a 35 mm eye reflex camera can be attached to the camera body. The present invention relates to a camera configured to be attached to a camera.

[Background of the Invention] A conventionally known 35 mm eye reflex camera is configured so that various accessories can be attached to the camera body in order to enable a variety of shooting. In other words, it differs depending on the built-in mechanism of the camera body.

For example, in non-electric cameras that do not have a film winding motor inside the camera body, a removable electric film winding mechanism called a motor drive or winder is used as an accessory. In electric cameras that have a built-in winding motor, the battery compartment is attached to the camera body as an accessory.

In addition to the film winding motor, its control circuit, and speed reduction mechanism, the motor drive and winder also house a battery, and the motor is driven by the battery. On the outer surface of the motor drive and camera body, there are holes for exchanging control signals (weak voltage signals representing control information) between the various control circuits inside the camera body and the control circuit inside the motor drive (or winder). A control signal connection terminal is provided, and when the motor drive is attached to the camera body, a weak voltage control signal is exchanged between the camera body and the motor drive through this terminal, and the shutter is activated within the camera body. Release is performed by an electrical signal. (Please note that the motor drive has a built-in battery for driving the motor, so a large current such as the motor drive current does not flow through the control signal connection terminal.) The motor drive is usually located on one side of the camera body. Since the motor drive is attached to the camera body in a protruding state, the outer surface of the motor drive is often designed as a grip to improve the holding ability of the camera.

In addition to the grip, a shutter release operating member may also be provided on the outer surface of the motor drive.

In a non-electric camera that uses a motor drive as an accessory, the internal mechanism of the camera body is mainly based on a conventional mechanical interlocking mechanism, so the camera body is quite large and heavy. Furthermore, the motor drive was large and heavy, so the camera with the motor drive attached to the camera body was large and difficult to hold. Furthermore, since the motor drive is large, there is no room for attaching other accessories to the camera body, and as a result, the development of accessories and the diversification of the camera's functions have been hindered. Moreover, since the shape of the grip formed on the outer surface of the motor drive depends on the shape and dimensions of the motor drive, it has been impossible to achieve an elegant grip with excellent holding properties.

On the other hand, in electric cameras where the battery compartment is an accessory, the size of the accessory can be smaller than that of a motor drive, and there is therefore more room around the outer periphery of the camera body to attach various accessories. but,
In this camera, the motor is inside the camera body and the battery is outside the camera body, so the supply current to the motor is passed through the connection terminals provided on the outside of the battery compartment (the outside of the accessory) and the outside of the camera body. Since it is necessary to provide a power terminal for the power supply, there is a drawback that heat generation and power loss occur due to contact resistance at the power terminal.

(The motor drive current is significantly larger than the control signal current, so if a power connection terminal is provided on the mounting surface between the accessory and the camera body, heat generation and power loss will occur due to contact resistance at the terminal.) ) Also, in this camera, the outside of the battery compartment is configured as a grip, and the grip (i.e., an accessory that also serves as the battery compartment) is removable from the camera body, but the shape of the grip and Since the dimensions are limited by the shape and dimensions of the battery storage chamber (and battery), it has not been possible to realize an elegant grip with excellent holding properties.

[Object of the Invention] An object of the present invention is to provide a camera having an elegant grip that is removable from the camera body and has excellent holding properties, and also to provide a camera with an elegant grip that is detachable from the camera body and has an excellent grip for the motor drive current. An object of the present invention is to provide a camera without a power connection terminal.

[Summary of the Invention] A camera according to the present invention includes a camera body having a control signal terminal and a battery storage chamber, a control signal terminal that contacts the control signal connection terminal, and a battery storage chamber. It is characterized by being comprised of a removable grip equipped with a portion that serves as a lid. In the camera of this invention, since the grip does not include a motor drive or a battery storage chamber, it is possible to construct the grip as an elegant grip with good holding property, and it is also possible to use electric power between the camera body and the grip. Since there is no need to provide a connection terminal for motor drive current (a connection terminal for motor drive current), there is no risk of heat generation or resistance loss occurring at the terminal, and the battery life can be extended. Furthermore, since the grip can be configured as a small accessory to the camera body, various accessories can be prepared for the camera body, and the degree of freedom in arranging the release member is increased.

Since the remote control is in contact with C, if the cable connected to the remote control is connected to the cable connection ring 12, the shutter release of the camera can be performed using the remote control.

The camera of the present invention includes a fitting part (that is, a nesting part 91) that fits into the battery storage chamber of the camera body, a hole 9h into which the positioning boss 18 of the camera body is inserted, and a steady rest member 19 of the camera body. The grip is provided with a recess 8C into which the grip is inserted, and when the grip is attached to the camera body, the grip and the camera body are positioned at these three locations, so that the grip can be accurately and accurately positioned relative to the camera body. Not only can the grip be quickly positioned, but also the grip can be quickly temporarily attached to the camera body. Furthermore, when taking pictures with the camera after the grip is attached, the grip 200 is
A force acting on the grip 200 acts on the grip 200 to rotate the lens 0 about the vertical axis. Since the grip and the camera body are connected using the two fitting parts of the steady rest member 19,
Even if the above-mentioned force acts on the grip, the grip will not shake against the camera body.

As shown in FIG. 2, when the grip 200 is fastened to the camera body 100,
When removing it, the operation described above may be reversed.

That is, first, loosen the fastening screw 11 and tighten the screw shaft 1.
1b from inside the tightening screw receiver 6 to the left side in FIG. As a result, the switch piece 34 comes into contact with the switch piece 36, and the switch piece 36 is grounded.

Next, when grip 200 is grasped by hand and rotated in the direction opposite to the direction of the arrow in FIG. Stop member 19
escapes from the recess 8c of the grip 200. At the same time, the nesting part 9fl is pulled out from the battery storage chamber 2a, so that the battery 1 is moved into the battery storage chamber 2a by the elastic force of the electric contact piece 44.
However, since the battery holding member 21 is provided near the entrance of the battery storage chamber 2a, the end surface 1d of the battery 1 engages with the surface 21e of the holding member 21, and as a result, Escape of the battery 1 from the battery storage chamber 2a is prevented. At this time, the battery 1 is held by the electric contact piece 44 and the battery holding member 21, so even after the grip is removed, the electronic circuit and memory inside the camera body are still connected to the power supply.
The information stored in the memory will not be lost.

When removing the battery 1 from the camera body, rotate the operation knob 21d of the battery holding member 21 counterclockwise with your finger in the direction shown in FIG.
The battery 1 can be taken out from the battery storage chamber 2a by retracting it to a position above the opening a and tilting the camera body to the right.

Note that when loading the battery 1 into the battery storage chamber 2a, it is sufficient to simply push the battery 1 into the battery storage chamber 2a. In this case, if the battery 1 is further propelled with the tip end surface of the battery 1 in contact with the tapered surface 21c of the battery holding member 21 which is stationary in the position shown in FIG.
It is rotated counterclockwise in FIG. 3 about shaft 21a by a component of the thrust applied to point c, and is retracted from the battery storage chamber 2a to an upper position, making it possible to load the battery very easily.

[Effects of the Invention] In the camera of the present invention, the grip that is removably attached to the camera body is configured as a cover for the battery storage chamber within the camera body, and a motor drive, battery chamber, etc. are provided within the grip. Therefore, the grip can be constructed as an elegant grip with good holding properties. Furthermore, since there are no battery compartments, motor drives, etc. inside the grip, the grip can be made compact, which creates space for installing various accessories around the camera body. This makes it possible to attach various accessories. Furthermore, in the camera of the present invention, since a power supply, a motor, etc. are not provided within the grip, there is no need to provide a power connection terminal on the mounting surface between the grip and the camera body. There is no risk of unnecessary resistance loss or heat generation on the mounting surface with the grip.
