Abstract

PURPOSE:To reduce a space between the inner wall of a cartridge loading chamber and a cartridge barrel part and to prevent the cartridge from moving in a vertical direction by providing a positioning recessed groove in which the extruding edge of the facing side wall of the cartridge is fitted on the inner wall of the cartridge loading chamber. CONSTITUTION:The cartridge loading chamber 2 is formed in a curved shape correspondingly to the curvature of the periphery of the barrel part 11 of the cartridge 3, and the positioning recessed groove 13 in which the extruding outer edge 9' of the facing side wall 9 is fitted is provided on the inner wall of the chamber 2. Therefore the cartridge 3 can be loaded in a proper direction when it is loaded in such a manner that the side of its circular arc 9b is directed face to face with respect to the cartridge loading chamber 2 and the extruding edge 9' of the facing side wall 9 is fitted in the above-mentioned recessed groove 13. Thus, the moving operation of the cartridge in a vertical direction is certainly regulated and positioning in the cartridge loading chamber is surely performed.

A commonly used cartridge (container for storing bare roll film) is made by rolling up a metal body plate so that the part to which the light-shielding cloth is attached faces in a lip shape to form a body part, and wrapping the bare film inside the body part. After storing the spool, there are flat plate-shaped metal gaps (
(side wall) is fixed. Therefore, since the side wall is limited to a circular shape in nature, it is impossible to maintain a constant orientation during loading into a camera unless the film outlet is protruded in the form of a lip. In response to this, a cartridge has recently been proposed in which the body and side walls are molded from plastic. This plastic cartridge has the outer edge of the side wall protruding from the body and can be made into a non-circular shape, so the shape of the camera side made by the inner wall of the cartridge loading chamber and the camera back is matched to that shape. ), there is an advantage that the orientation at the time of loading can be kept constant without having to protrude the film outlet in the form of a lip.

(Problem to be Solved by the Invention) However, as described above, the outer edge of the opposite side wall of the cartridge protrudes from the body, so when loaded into the cartridge loading chamber, there is a large gap between the inner wall and the cartridge body. A gap was created. Therefore, the following problems have arisen in cameras equipped with a film sensitivity identification/reading device (DX).

That is, the film sensitivity identification reading device has a contact piece that reads the film sensitivity identification code displayed on the cartridge body protruding from the inner wall of the cartridge loading chamber, but as described above, the contact piece that reads the film sensitivity identification code displayed on the cartridge body is connected to the inner wall of the cartridge loading chamber and the cartridge body. If the gap is large, the protruding length of the contact piece also becomes long, and there is a risk that the film may be bent or broken when loading the film.

In addition, as long as the side wall of the plastic cartridge is formed into a non-circular shape, it will be securely fixed in the circumferential direction (film pulling direction), but it will easily move in the axial direction (vertical direction), so the contact piece will come into contact with the adjacent cord. There was also a problem that the code could be disconnected from the code.

This invention is intended to solve the above-mentioned problems, and it is possible to prevent the code reading contact piece protruding from the inner wall of the cartridge loading chamber from being bent or broken, and also to ensure positioning within the cartridge loading chamber. The purpose is to provide cameras.

The plastic cartridge 3 includes an opposing side wall 99 having a bearing hole 8 for bearing both ends of the spool 7, and the side wall 9.
It consists of a body part 11 having a film outlet 10 between 9 parts. The opposite side wall 9.9 protrudes from the body 11 at its outer edge 9' and is non-circular. That is, the area near the film outlet 10 has a rectangular shape 9a, and the other area has an arc 9b. Furthermore, the plastic cartridge 3 can be split into two along a diagonal line 12 passing through the center of the bearing hole 8 in order to facilitate storage and removal of the spool 7 on which the film is wound.

The cartridge loading chamber 2 has a body portion 11 of the cartridge 3.
The inner wall of the chamber 2 has a protruding outer edge 9 of the opposing side wall 9.
A positioning recessed groove 13.13 is provided in which the groove 13' is fitted. Therefore, when loading the cartridge 3 with the arc 9b side facing directly in front of the cartridge loading chamber 2, and with the protruding edges 9', 9' of the opposing side walls 9, 9 fitting into the grooves 13, 13, It is designed so that it can be loaded in the correct direction. In other words, sideways or backwards (square 9
If the side a is directly facing the cartridge loading chamber 2), loading is not possible, or the back M6 cannot be closed.

3, and connect the tip of the film pulled out from the cartridge 3 to the take-up reel.
When 6 is closed, the cartridge 3 is held down. As a result, the contact piece 14 protruding from the inner wall of the cartridge loading chamber 2 comes into strong contact with the film sensitivity identification code applied to the surface of the body of the cartridge 3. In this case, the cartridge 3 is securely fixed both in the circumferential direction and in the axial direction.
