Since the terminals 15 to 20 are exposed to the outside and electrically connected, consideration is given to corrosion such as gold plating.
Further, the IC 14 used in this embodiment has a shape molded with plastic or the like.

4 (a) and 4 (b) are devised to further reduce the size of the embodiment shown in FIG.
e Automated Bonding) method. An IC chip (not shown) is directly gang-bonded onto a pattern provided on a flexible printed circuit board (hereinafter, abbreviated as FPC) 25, and resin 24 is provided above and below the IC chip as shown in the sectional view of FIG. 4 (a). It is potted and sealed. Further, the plurality of resistors 23 'for preventing static electricity are provided by a carbon printing method, and the capacitor 22' is also made of a laminated type small component.

The partial delivery configured as described above will be referred to as an IC substrate 26 hereinafter.

By devising in this way, the IC substrate 26 itself has flexibility, and it becomes easy to store the IC substrate 26 in a bent state in a narrow space.

Further, the IC substrate 26 itself becomes the minimum unit for storing information, is easy to handle, and is stored in the IC by applying a power source and a digital signal to the terminals 15 to 20 exposed to the outside in a predetermined device. It is possible to read data and, conversely, store new data.

FIG. 5 (a) is an external view of an embodiment in which the IC substrate 26 shown in FIGS. A hole is formed in a part of the film cartridge (10) on the outside of the curved surface so that the terminals (15 to 20) of the IC substrate (26) are exposed. FIG. 2B is a transverse sectional view of FIG. 1A, and the IC substrate 26 is housed along the circumference of the film cartridge 10. FIG. 6 shows the camera 8 into which the film cartridge 10 thus constructed is loaded,
The contacts 101 to 106 and the terminals 20 to 15 in the camera 8 come into contact with each other to exchange data information.

7 (a) is similar to FIG. 5 (a) in that a terminal is provided on a part of the outer periphery of the film cartridge 10, but the position is flat so that the film 11 can be pulled out. It is another example in which it is arranged. This is effective, for example, when the IC substrate cannot be bent. (B) Figure 5
It is a cross-sectional view of the film cartridge 10 as in FIG. 6B, and the IC substrate 26 is housed in a relatively flat space. Film cartridge 10 configured in this way
The contact point on the camera 8 side when the
Unlike the illustrated embodiment, it is provided inside the back cover 9 of the camera 8 as shown in FIG. The contacts 101'-106 'are in contact with the terminals 20-15, respectively. Note that FIG. 9 shows the structure of the film cartridge 10 of the embodiment shown in FIGS. 5 and 7. That is, the film cartridge 10
Is two lids 110, inner cylinder 111, shaft 112, film 11, outer cylinder 1
The IC substrate 26 and the IC substrate 26 are mounted in close contact with the outer cylinder 113. The film cartridge 10 has upper and lower lids 11
The structure is fixed at 0. Also, if either lid 110 is removed, it will be disassembled as shown in Fig. 9, so IC
The substrate 26 can be easily taken in and out. Also inner cylinder
Since there is 111, the film 11 and the IC substrate 26 do not come into contact with each other. FIG. 10 (a) shows another embodiment, which is shown in FIGS.
It is an external view when terminals 15 to 20 are arranged in the lid portion unlike the embodiment shown in the drawing. (B) is a view of (a) viewed from directly above, (c) is a view of the IC substrate 26 viewed from the side, and in this embodiment, the shape of the IC substrate 26 is the film cartridge 10. It has a donut shape according to the shape of the lid 110. FIG. 11 shows the structure of the embodiment shown in FIG. Since the basic structure is as shown in FIG. 9, only different parts are shown in FIG. That is, the portion composed of the lid 110, the outer cylinder 113, the film 11, and the shaft 112 from the lower side is the bottom view of FIG. 11, on which the inner lid 110 ″, the IC substrate 26, and the terminals are placed. The film cartridge 10 is constructed by covering the lid 110 'with a hole for taking it out. In this embodiment, the inner cylinder 111 is not used. Also in this embodiment, the IC substrate 26 is taken in and out. It can be easily done by attaching and detaching.

Although the contacts in the camera in this embodiment are not shown in the drawings, those having a structure as shown in FIG. 10 are located at an arrow A in FIG. 6 and terminals 15 to 20 are opposite to those in the tenth position. For those configured to be on the side, arrow B in FIG. 6
Needless to say, there is a contact point at.

FIG. 12 shows the IC substrate 26 on the shaft 11 of the film cartridge 10.
It is an external view of the example arrange | positioned in 2 '. The diagram (b) is a diagram in which the shaft 112 'is divided into two, and the IC substrate 26 shown in the diagram (c) is arranged in this. (B) The portion K in the figure is a contact piece configured so that it can always come into contact with a contact on the camera side, which will be described later, even if the shaft 112 'rotates, and terminals 15 to 20 are IC boards.
Shafts 112'a and 112 'when 26 is placed in shaft 112'
It is adapted to contact each contact piece of b, and 15 'to 20' are connected to 15 to 20, respectively. The other structure is basically the same as that shown in FIG. 9 and is omitted here. The film cartridge 10 configured as shown in FIG. 12 (a) is configured to contact the contacts 101 ″ to 106 ″ of the camera 8 as shown in FIG. 13 to exchange data information. That is, when the film cartridge 10 is housed in the camera 8, the contacts 101 ″ to contact the shaft 112 ′.
106 ″ is arranged.

Further, in the figure (b), the contact portion with the camera is the shaft 11
It was provided on the outer circumference of 2 ', but as shown in FIG.
2 ″ may be on the inside. Note that FIG. (D) shows an embodiment in which the contact portion with the camera is provided on the inside. That is, as in FIG. Also axis 112 ″
Is divided into 112 "a and 112" b, but the IC substrate 26 (not shown) is placed in the shaft, then 112 "a and 112" b are aligned in the directions of the arrows l and m, respectively, and the shaft cap 120 is further marked with the arrow. The terminal of the IC substrate and the contact piece arranged on the inner circumference of the shaft cap 120 can be brought into contact with each other by covering in the direction of n. The method of contact with the contacts when the film cartridge is housed in the camera is also the same as the concept shown in FIG. 13, so the description thereof is omitted here.

Although the flexible IC substrate 26 is described in FIG. 4 and the like, in FIG. 14, an inflexible IC card 120 is shown as an example.

In FIG. 14, the film cartridge 10 and the film 11
1 is similar to the conventional example, but an IC card 120 is removably attached to the side surface of the cartridge 10 as shown by an arrow.

The IC card 120 is integrated as a whole with a plastic mold or the like, and the IC chip 121 indicated by the broken line is inside.
The terminals 15 to 20 are IC
It is exposed from the side of the card 120. IC chip 121 and terminal 15
Illustration of the connections between 20 and the peripheral parts shown in FIG. 2 and the like is omitted.

Therefore, the function of the IC card 120 is exactly the same as that of the IC substrate of FIG. 4, but it is excellent in easiness of handling and durability. Here, the plastic mold forming the IC card 120 may have an antistatic effect by having a certain degree of conductivity. However, since the terminals 15 to 20 are present on the surface thereof, it is necessary that the terminals 15 to 20 are not completely electrically conductive and have a high resistance value such that leakage from the terminals 15 to 20 can be ignored.

When purchasing a film, the IC card 120 is fixed to the film cartridge 10, and the photographer inserts the same shape into the camera to take a picture.

This is shown in FIG. Camera body 122 and case back 9
A film cartridge 10 with an IC card 120 is loaded between them, and terminals 15 to 20 on the IC card 120 have a plurality of contacts 101 arranged so as to project from the camera body 122.
To 106 are brought into contact with each other to establish electrical conduction, and data communication is performed between the IC 121 and a circuit in the camera (not shown).

After shooting, at the photo lab, when the film 11 is pulled out from the film cartridge 10 for development and printing on photographic paper, the information stored in the removed IC card 120 is read out and used by a predetermined device. Work to be done at the same time.

After this, the film cartridge 10 itself is no longer needed and therefore discarded, but the IC card 120 is returned to the photographer for storage together with the developed film pieces and prints.

Here, since the IC card 120 has a structure that can be attached to and detached from the film cartridge 10, it can be easily used repeatedly. For example, if you use an E ² PROM for the IC121, you can freely erase it as well as electrically write it, so you can collect the IC card 120 you no longer need and reuse it in a film cartridge filled with new film. There is.

FIG. 16 shows another embodiment. Film cartridge 12
The shape of 4 is completely different from the conventional method, and here the square type is taken as an example. One side wall of the film cartridge 124 can be attached and detached as shown in the figure, and the side wall itself is the IC.
Functions as the card 129. At the time of shooting, the IC card 1 is inserted into the recesses 125 and 126 provided in the film cartridge 124.
The 29 convex portions 127 and 128 are fitted to each other to form a dark box. Needless to say, the film 11 is wound around the shaft as in the conventional case.

Since the relationship with the camera at the time of shooting is the same as in FIG. 15, the description is omitted.

At the end of shooting, slide the IC card 129 out of the film cartridge 124 and pull it out as shown in FIG.
It is handled in the same manner as the IC card 120 in the figure. The structure of the terminals and IC 121 provided on the IC card 129 is the same as that of the IC card 120. The advantage of the IC card 129 is that the case that constitutes the film cartridge 125 itself is a container for the IC 121, which is efficient in terms of price and space.

In Fig. 16, the structure that can be slidably attached to the rectangular cartridge is shown, but the structure is not limited to this, and the same effect can be obtained as a type of IC card that can be inserted into the cylindrical cartridge by using the elasticity of plastic. Is obtained.

FIG. 17 shows a circuit block diagram of a camera in which the conventional film cartridge 10 and the film cartridge 124 of this embodiment can be used in common. As is well known, the film cartridge 10 of the conventional system is provided with a code such as ISO sensitivity and the number of films as a DX code, and it is naturally impossible to perform the data communication shown in this embodiment. On the contrary, the film cartridge 124 can communicate data, but cannot output a static code like the DX code.

The signal lines from the contacts 101 to 106 on the camera side shown in FIG. 15 are transmitted to the CPU 131 via the interface circuit 130.

 The operation is performed as follows.

First, when using the conventional film cartridge 10,
The CPU 131 operates to identify the loaded film through the interface circuit 130. It is the second
By using the handshake terminal described in the drawing, first, a trigger signal is transmitted, and then a predetermined signal is returned to determine whether or not the film cartridge is capable of data communication. In this case, there is no reply signal after transmitting the trigger signal, and the CPU 131 confirms this and then enters the DX code detection routine by the conventional method.

When the film cartridge 124 is loaded, a reply signal is generated subsequent to the trigger signal, so that the data communication of the information signal is performed with each other.

This flow is shown in FIG. First, the film cartridge is discriminated depending on whether the loaded film is capable of data communication, and the subsequent processing is changed according to the result of the discrimination.

FIG. 19 (a) is a view showing an embodiment in which the IC 14 has peripheral components mounted on a cassette type film cartridge 201 having film storage portions 250 and 251 on both sides. In this embodiment, the IC 201 and peripheral parts are mounted on the cartridge 201.
However, it goes without saying that the cartridge 201 may have a two-layer structure and these parts may be provided inside. The details have already been described with reference to FIGS.

19 (b) and (c) show contacts 215 to 218, 235 to 238 and terminals 225 to 225 in the case of electrically connecting the cartridges 201 and 202 in which circuits are arranged as shown in FIG. 228, 245
248 is shown, in which (b) shows that the terminals 225 to 228 are provided on the surface of the cartridge 201 facing the back cover 9 and
This is an embodiment in which the contacts 215 to 218 are brought into contact with each other when they are bound to obtain an electrical connection. Further, in (c), terminals 245 to 248 are provided on the inner surface of the cartridge 202 as shown in the figure, and when the cartridge 202 is set in the camera 8, the contact 2 of the camera 8
This is an embodiment in which the electrical connection is obtained by connecting with 35 to 238.

In FIG. 19, there are four connection surfaces for convenience of explanation, but it is needless to say that the number of connection surfaces may be six or more as shown in FIGS. 3 and 4.

In such film cartridges 201 and 202, since it is possible to make the shape having a relatively large number of flat parts, the IC
Storage area for circuit parts including 14 and terminals 225 to 228, 245-2
There are 48 installation sites with flexibility.

〔The invention's effect〕

As described above, according to the present invention, data communication with the information storage semiconductor housed in the film cartridge or in the film cartridge itself becomes very easy in a state where the camera is loaded. Moreover, since the unit including the semiconductor can be easily removed, it is possible to perform data communication with an external device other than the camera. Further, since the storage portion for storing the semiconductor can be removed from the film cartridge, it is not necessary to store the entire film cartridge when storing the information stored in the semiconductor (only the storage portion needs to be stored). Can be stored without taking up space.

Also, by deleting unnecessary information, it can be attached to another cartridge and reused (recycled).
You can also plan.

In addition to the above, the structure shown in the example has the advantage of being extremely easy to handle and store.
