DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the main parts of a film supply device 10 for a developing device to which the present invention is applied. In this film supply device 10 for a developing device, a 135 size film is stored in a cartridge, which is a film storage container, as a first film, and a film of size 135 is stored in, for example, a film storage container as a second film. A brownie-sized film is used.

FIG. 4 shows the connection between the cartridge 26, which is a film storage container containing 135 size film 14, and the reader 16. Adhesive tape 15 is attached to the tip of the film 14 pulled out from the cartridge 26.
A reader 16 is connected to each cassette 1, and a large number of combinations of the cartridge 26 and the reader 16 are connected to the cassette 1.
8 (shown by phantom lines in FIG. 1), and the first leader 16 is supplied from the inside of the cassette 18 to the film supply device 10 for the developing device. However, the leader 16 may be manually fed into the developing device film supply device 10 by an operator without using the cassette 18.

As shown in FIGS. 5 and 6, a brownie-sized film 128 was wound up into a roll and stored in the film storage container 100, and the leading end was pulled out from the outlet and connected to the rear end of the leader 16. In this state, the film is fed into the developing device film supply device 10.

Film storage container 10 shown in FIGS. 5 and 6
0, an inner cylinder 204 is housed in an outer cylinder 202, and a film 128 is housed in the outer cylinder 202 and inner cylinder 204 in the form of a roll. The peripheral surface of the outer cylinder 202 is formed in a substantially semicircular shape, and end plates 202A are fixed to both ends in the width direction. The inner cylinder 204 is also formed in a substantially semicircular shape, and the outer periphery is in contact with the inner periphery of the outer cylinder 202.
4A are each fixed. These end plates 204A are arranged inside the end plate 202A, and a protrusion 204B protruding from the axial center is pivotally supported by the axial center of the end plate 202A, so that the inner cylinder 204 can be rotated inside the outer cylinder 202. There is.

Film 128 in the open state shown in FIG.
When the inner cylinder 204 is accommodated, the inner cylinder 204 is rotated around the outer cylinder 202, and a film is placed between the guide plate 206 fixed to the end of the inner cylinder 204 and the guide plate 208 fixed to the end of the outer cylinder 202. The drawn end of the tube is held between the two, and the insides of the inner and outer tubes are shielded from light. In this light-blocking state, the engaging arm 212 protruding from the end plate 202A locks the guide plate 208 and the inner cylinder 202
4 is designed to prevent accidental opening.

Since this film storage container 100 stores a Brownie film 128, its width is larger than that of a commercially available cartridge 26 that stores a 135 size film 14. Note that the film 128 is stored in a rolled form and has no core, so that its entire length can be pulled out from the film storage container 100.

As shown in FIG. 1, a supply section lid 106 is pivotally supported on the developing device main body 102 via a pin 104, and is configured to cover a supply section 110 for delivering the film to the developing section 108. A cylindrical portion 112 serving as a cassette connecting portion protrudes diagonally upward from the supply portion lid 106, and is adapted to accommodate the cassette 18.

As shown in FIGS. 2 and 3, the supply section 110
is provided with an endless drive belt 162, and a pair of gears 16
A protrusion 162A that is wrapped around the gears 164 and 166 and protrudes from the inner circumference is engaged with the gears 164 and 166. Further, a protrusion 16 formed on the outer periphery of the endless drive belt 162
2B engages with the opening 16A of the leader 16 to feed the leader 16 to the developing section 108.

As shown in FIGS. 2 and 3, gear 164
A pair of film container support members 92 are arranged on both sides of the film container. This film case support member 92 has a base 9
4, a pair of side portions 96 bent in the same direction from both sides of the base portion 94, and a film container support disposed inside surrounded by the base portion 94 and the pair of side portions 96 and integrally formed with the base portion 94. 98.

The film container support portion 98 has a pair of side portions 9.
6, an arc-shaped first support portion 98A is formed. A part of the outer periphery of the cartridge 26 containing a 135 size film comes into contact with this support portion 98A. Further, on both sides of the support portion 98A, a pair of ribs 98 protrude from the support portion toward the upstream side in the film feeding direction.
B is formed to position the cartridge 26 in the film width direction. For this reason, these ribs 98B are formed with an inclination so that the distance between them becomes gradually narrower toward the base, that is, the connecting portion to the support portion 98A.

The distance between the bases of these ribs 98B is 13
The length is set to be slightly longer than the length in the film width direction of the cartridge 26 which accommodates five sizes of films, that is, the length in the width direction. Therefore, these ribs 98B
The cartridge 26 is supported in contact with the support portion 98A between
is limited in axial movement. This prevents the film pulled out from the cartridge 26 from meandering in the width direction.

The pair of side portions 96 are plate-shaped and extend parallel to each other with a supporting portion 98A sandwiched therebetween, and a second supporting portion 96A is formed at the tip thereof in the shape of a concave arc. As shown in phantom lines in FIG. 3, this second support portion 96A is adapted to abut and support a portion of the outer periphery of the film storage container 100 in which the Brownie film is stored. This second support portion 96A is located upstream in the film feeding direction (on the left side in FIG. 1) than the first support portion 98A.
The supporting positions of the cartridge containing the 35 size film and the film storage container 100 containing the Brownie film are shifted from each other in the film feeding direction.

Further, the upper surfaces of the pair of side portions 96 are sloped downward from the middle portion to the tip portion to form a guide portion 96B. The leader 16 connected to the leading end of the film is slidably guided on this guide portion 96B.

The upper part of the base 94 is cut into a rectangular shape to form a film passage groove 94A. Support part 98A
The lower part of the side part 96 extends downward from the pair of side parts 96,
A counterbore hole 94B is provided to penetrate therethrough. The bolt 101 passing through this counterbore hole 94B is screwed into the upper part of the arm plate 132, and the arm plate 132 is attached to the film support member 9.
It is connected to 2.

Both sides of the arm plate 132 are bent at substantially right angles in the same direction to form guide portions 134 and 136. The film container support member 92, which is provided between these guide portions 134 and 136 for guiding the empty cartridge 26 to be dropped downward after taking out the film, rotates around a shaft 133 passing through the lower end of the arm body 132. It is rotatable so that its upper part can move in the direction toward and away from the developing section 108, and is normally pressed in the direction away from the developing section 108 by the biasing force of an elastic body. However, when all the 135 films 14 in the cartridge 26 are pulled out, the tension acting on the films 14 is received through the core 26A, allowing access to the developing section 108. This approaching state is detected by a limit switch (not shown), whereby the cutter 11 is activated and the rear end portion of the film 14 is cut.

An opening/closing lid 222 is provided corresponding to the cartridge 26 and the film storage container 100 supported by the film container support member 92. This opening/closing lid 222 is attached to a bracket 22 fixed to the film supply device 10 for the developing device.
4 (FIG. 1) via a hinge 226. A tension coil spring 228 is interposed between the opening/closing lid 222 and the bracket 224, and it is movable from the horizontal state shown in FIGS. 1 and 3 to the vertical state shown in FIG. The tension coil spring 228 is adapted to perform a moderating function so as to selectively take the position. That is, the opening/closing lid 222 rotates downward in the direction of arrow A from the state shown in FIG.
However, when the opening/closing lid 222 passes the midpoint (when the axis of the tension coil spring 228 passes the center of rotation of the hinge 226 in FIG. 1), the tension coil spring 228 rotates the opening/closing lid 222 further downward. It has a moderation means for biasing it to perform a snap action operation which leads to the state shown in FIG.

The opening/closing lid 222 closes the opening 232 provided between the film container support member 92 and the bracket 224 in the state shown in FIG. 3 to prevent the film container 100 from falling, and in the state shown in FIG. opening 2
32 is opened to allow the cartridge 26 to fall under its own weight. Further, a lever 234 is fixed to this opening/closing lid 222, and this lever 234 is connected to the bracket 222.
The lid 22 protrudes from the opening 224A provided in the
The arrangement of 2 can be controlled manually. That is, film size display 2 is provided near the periphery of the opening 224A.
36, and if the film corresponding to the film container support member 92 is a 135 film to be pulled out from the cartridge 26, the operator moves the lever 234 in the direction indicated by 135 as shown in FIG. With the opening/closing lid 222 in an open state with the opening 232, 120, 126,
In the case of a 110 size film, by moving the lever 234 in the opposite direction (in the direction of arrow B), the opening 232 can be closed by the opening/closing lid 222 as shown in FIG.

Next, the operation of this embodiment will be explained. 135 size film 14 stored in a commercially available cartridge 26
When the cartridge is inserted into the film supply device 10 for a developing device to perform a developing operation, the leader 16 is connected to the film 14 protruding from the cartridge 26 as shown in FIG. In this state, the cartridge 26 and the leader 16 are housed in the cassette 18, and the leader 16 is engaged with the endless drive belt 162 and fed by automatic feeding or by manual operation. In this case, the operator operates the lever 234 as shown in FIG. 2 to open the opening 232 with the opening/closing lid 222. Therefore, when the leader 16 is engaged with the endless drive belt 162 and fed into the developing section 108, the cartridge 26 is supported by the ribs 98B of the film container support member 92, as shown in phantom lines in FIG. As a result, the film 14 pulled out from the cartridge 26 is reliably fed into the developing section 108, and the developing device advances.

When most of the film in the cartridge 26 is fed into the guide plate 208, the tail end of the film 14 is locked to the winding core 26A, so the cartridge 26 is pulled toward the developing section 108. As a result, the film container support member 92 is rotated around the shaft 133, and the cutter 11
is activated, and the end of the film 14 is cut off. Here, the cartridge 26 falls from the first support portion 98A through the open opening 232 and is accumulated. The accumulated cartridges 26 are reused or taken to a disassembly process to be utilized as resources.

On the other hand, as shown in FIGS. 5 and 6, a film storage container 100 containing a Brownie film 128 is provided.
When bringing the material into the supply section 110, the operator applies operating force to the lever 234 in advance to close the opening 232 with the opening/closing lid 222, as shown in FIG. Here, the leader 16 connected to the film 128 is inserted into the protrusion 1.
62B. As a result, the leader 16, which receives a driving force from the protrusion 162B, pulls out the film 128 in the film storage container 100 and sends it to the developing section 108, where a series of developing processes are performed. In this pulled-out state of the Brownie film 128, since the end of the Brownie film 128 does not have a winding core, the pull-out reaction force does not act on the film storage container 100, and the film storage container 100 is moved to the second support portion 96A. It attempts to break away from the contact state and fall under its own weight. Since the opening/closing lid 222 prevents the film storage container 100 from falling due to its own weight, the film storage container 100 does not fall significantly due to its own weight. Therefore, the brownie film 128 rapidly moves relative to the film storage container 100 and touches the film surface. It will not cause any damage.

Further, after all the films 128 have been pulled out from the film storage container 100 and sent to the developing section 108, the operator opens the supply section lid 106 and then closes the opening/closing lid 2.
The film storage container 100 remaining on the film storage container 10 is taken out and another film 128 is placed on the film storage container 10 again.
You can do the work of loading it into 0.

[0031] In addition, 126 size film, 11
Even when supplying a 0 size film to the developing device, the lever 234 may be moved in accordance with the film size display 236 to sort the film storage container.

[0032] In the above embodiment, the structure in which the operator directly operates the lever 234 manually was explained.
The opening/closing lid 222 may be moved to the state shown in FIG. 2 or 3 by electric driving force or the like when the operator operates a key switch or a selection button.

[0033]

As described above, the present invention has an excellent effect in that it is possible to sort the film storage container after taking out the film according to the type of film.
