Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock device for a cartridge lid in a cartridge chamber which prohibits taking out a film cartridge.

[0002]

2. Description of the Related Art There is a case where a film cartridge which is being photographed is taken out while leaving unused frames. For example, there is a case where a film having a different exposure sensitivity from the loaded film being photographed is used. However, when a new cartridge is loaded in place of the used cartridge that was taken out in the middle, or when the previous cartridge is reloaded in the camera, the various conditions of the camera should be adjusted according to the film information. It is necessary to reset the conditions. An apparatus for detecting such film information is disclosed in JP-A-5-313234. This device sets various conditions of the camera in accordance with the state of the film of the loaded cartridge by detecting the information of the cartridge by using electric means. However, since the information on the film is detected electrically, if the battery is removed and replaced with another cartridge, the state of the film cannot be detected, resulting in a malfunction.

It is an object of the present invention to provide a cartridge lid locking device which does not cause a malfunction in the camera even if the cartridges are replaced.

[0007]

1 shows an embodiment of a lock device for a cartridge lid according to the present invention, in which a cartridge (not shown) is loaded, a battery is housed in a battery chamber, and a battery lid is closed. It is a perspective view of the state in. In FIG. 1, a battery chamber 2 accommodating a battery 1 is opened and closed by a battery lid 3 which rotates around a rotating shaft 4. Battery lid 3
A protrusion 3a is provided on the back side of the. The cartridge (not shown) is a cartridge lid 6 that rotates about a rotation shaft 7.
It is stored in a cartridge chamber that can be opened and closed by. On the back side of the cartridge lid 6, a locking portion 6a having a bent tip is provided in a protruding manner.

A slide stopper 11, which is a substantially plate-shaped member having a notch 11a, is a pin 10 inserted in an elongated hole 11b.
Is slidably attached in the direction of arrow AB along the spring 1
It is urged in the A direction by 2. In the state shown in FIG. 1, the slide stopper 11 contacts the battery 1 at one end 11c and is pushed in the B direction against the spring force of the spring 12. The rotation stopper 14 rotatably mounted about the rotation shaft 13 has a first contact portion 14a and a second contact portion 14b.
1, and is biased by the spring 15 in the clockwise direction in FIG. Further, a suppressing member 16 that suppresses the clockwise rotation within a certain range is provided. When the battery lid 3 is closed, the abutting portion 14 a is the protruding portion 3 a of the battery lid 3.
And the rotation stopper 14 is pushed counterclockwise against the spring force of the spring 15. The locking member 18 includes a first protruding portion 18b, a second protruding portion 18c, a locking portion 18d having a bent front end, and a knob 19, and is slidably attached along the fixing pin 17 inserted into the elongated hole 18a. At the same time, it is biased in the C direction by the spring 20. The locking portion 18d engages with the locking portion 6a of the cartridge lid 6 and prohibits the cartridge lid 6 from being opened.

FIG. 2 shows a state in which the locking member 18 is slid in the D direction by the knob 19 from the state of FIG. FIG.
In, the first protrusion 18 b of the locking member 18 faces the notch 11 a of the slide stopper 11, and the second protrusion 18 b
c is at a position not facing the second contact portion 14b of the rotation stopper 14. Therefore, as shown in FIG.
Is operated in the D direction, the locking lever 18 can be slid in the D direction against the spring force of the spring 20.
By sliding the locking lever 18 in the D direction, the locking portion 6
Since the engagement between a and the locking portion 18d is released, the cartridge lid 6 can be rotated to be in the open state. That is, when the battery 1 is housed in the battery chamber 2 and the battery lid 3 is closed, the locking lever 18 can be slid, and the cartridge lid 6 can be opened to take out the cartridge. .

FIG. 3 shows a state in which the battery 1 is housed in the battery chamber 2 and the battery lid 3 is open. At this time, since the one end 11c of the slide stopper 11 and the battery 1 are in contact with each other, the slide stopper 11 is in a state of sliding in the B direction in FIG. Therefore, the notch 11 a of the slide stopper 11 is located at a position facing the first protrusion 18 b of the slide stopper 18. On the other hand, the spring 15
The first contact portion 14a of the rotation stopper 14 biased in the clockwise direction by the above does not contact with the protruding portion 3a of the battery lid 3,
Therefore, the rotation stopper 14 is rotated in the clockwise direction by the spring 15 until the side portion of the first contact portion 14 a contacts the suppressing member 16. At this time, the second contact portion 14b is in a position facing the second protrusion 18c of the locking lever 18. In this way, the second contact portion 14b and the second protrusion 18c
Since the locking levers 18 are opposed to each other, the locking levers 18 are slid slightly to the right and both abut each other, and further sliding of the locking levers 18 is suppressed. Therefore, the locking portion 18
The engagement between d and the locking portion 6a does not come off, and the cartridge lid 6 cannot be opened.

FIG. 4 shows a state in which the battery 1 is not housed in the battery chamber 2 and only the battery lid 3 is closed. The protruding portion 3 a provided on the battery lid 3 is in contact with the first contact portion 14 a of the rotary stopper 14. Therefore, as described with reference to FIG. 1, the rotation stopper 14 is pushed counterclockwise to rotate, and the second contact portion 14b of the rotation stopper 14 does not face the second protrusion 18c of the locking lever 18. Have been evacuated to. In the state where the battery 1 is not present, the slide stopper 11 biased in the direction A by the spring 12 is used until the elongated hole 11b collides with the fixing pin 10.
Is in the position where it slides in the direction A. At this time, the first protrusion 18b of the locking lever 18 does not face the notch 11a of the slide stopper 11. Therefore, when the locking lever 18 is slightly slid in the D direction, the first protrusion 18b abuts the slide stopper 11, and the locking lever 18 cannot be slid to the right any further.
As in the case of FIG. 3, the cartridge lid 6 cannot be opened.

As described above, in the embodiment of the present invention, the battery 1 is housed in the battery chamber 2 and the battery lid 3 is provided.
The cartridge lid 6 can be closed only when is closed. In addition, regardless of the state of the battery lid,
The cartridge lid may be opened when a battery is inserted. Further, for example, in a camera having a structure in which the battery lid does not close unless the battery is inserted, the cartridge lid may be always opened when the battery lid is closed.

In the embodiment of the present invention, the locking lever 18 is the prohibiting member according to claims 1 to 3, the rotation stopper 14 is the prohibiting member according to claim 1, and the slide stopper 11 is claim 2. The slide stopper 11 and the rotation stopper 14 constitute the prohibition member described in claim 3, respectively.

[0014]

As described above, according to the present invention,
When the battery lid is closed (Claim 1), when the battery is stored in the battery chamber (Claim 2), or when the battery is stored in the battery chamber and the battery cover is in the closed state (Claim 1). Only in 3), the cartridge lid can be opened to take out the cartridge, and in other cases, the cartridge cannot be taken out. Therefore, in the camera that electrically detects the information of the film, it is possible to prevent the malfunction of the camera due to the replacement of the cartridge while the detection mechanism or the like is not operating because the battery is not loaded.
