Description

Detailed Description of the Invention [Industrial Application Field] The present invention supports a film storage box containing exposure film and guides the film pulled out from the inside of the film storage box to a developing device. The present invention relates to a film guide device for a developing device.

[Prior Art] There is a developing device in which photographed film is fed into the developing device by a film feeding device (Japanese Patent Application Laid-Open No. 1983-1999).
No. 58445, Japanese Unexamined Patent Publication No. 63-61250).

In this device, the film is connected to the rear end of a thin leader made of synthetic resin, and an engagement hole formed in this league engages with a conveyance sprocket in the developing device to receive driving force and is conveyed through the developing device. It has become so.

The types of films supplied by this supply device include 135 size, 110 size, 126 size, and 120 size (Brownie film). The 135 size film is wound onto a spool in the cartridge, which is a film storage box, and is pulled out from the film outlet of the cartridge.

In addition, for 110 size and 126 size film, the cartridge is broken, the film is taken out, and the film is stored rolled in a separate supply film storage box (film magazine), which can be opened and closed with a lid. It is pulled out from the outlet.

In addition, the 120 size film is rolled up into a roll with the edge of the photosensitive surface stuck to a part of the overlapped light-shielding paper, and then peeled off from the light-shielding paper.
Only the film, such as 10 size or 126 size, is placed in a separate supply film storage box and is supplied to a developing device where it is developed.

When supplying a 135 size film to the developing device, a league is connected to the leading end of the 135 size film housed in the cartridge, and when the league is drawn into the developing device, the cartridge is transferred to the developing device. When the league comes into contact with the case support member and is further conveyed toward the developing device, the film in the cartridge is pulled out and sent to each processing tank in the developing device.

Further, when supplying another film such as a 120 size film, a so-called brownie film, a film magazine containing the brownie film is attached to the film supply port. When the league to which the leading end of the Brownie film is connected is drawn into the developer mounting, the film magazine in the holder comes into contact with the film case support member. Furthermore, as the league is transported, the brownie film in the film magazine is pulled out,
Supplied into the developing device.

[Problems to be Solved by the Invention] However, when trying to support, for example, a cartridge containing a 135-size film and a film magazine containing a Brownie-sized film with the same support member, the width of the Brownie film becomes too large. Since the dimensions are wider than the 135 size film, the cartridge containing the 135 size film will move unnecessarily in the width direction, causing the 135 size film to move unnecessarily.
It is not possible to position the cartridge in the width direction containing a film of the same size. This causes the 135 size film to meander in the width direction, resulting in poor detection by the film sensor and poor engagement of the sprocket with the perforations.

Therefore, if a film case support member is manufactured according to the dimensions of a cartridge containing a 135-size film, the positioning of the film magazine containing the brownie film in the width direction becomes uncertain, and the brownie film may meander. become.

In consideration of the above-mentioned fact, the present invention aims to reliably support and fill film storage boxes having different width dimensions.

[Means to solve the problem]

The present invention provides a film guide device for a developing device that selectively guides a narrow first film storage box, a narrow film stored therein, and a wide film stored in a second wide film storage box to a developing section. a first supporting portion disposed on the downstream side in the film feeding direction and supporting the first film storage box by coming into contact with the outer circumferential portion of the first film storage box when the film is being fed to the developing device; a first control means for preventing movement of the first film storage box supported by the support part in the film width direction; a second support part that supports the second film storage box by coming into contact with a part of the outer periphery of the storage box; and a second control means that prevents the second film storage box supported by the second support part from moving in the film width direction. It is characterized by having the following.

Therefore, in the present invention, a film storage box containing relatively narrow films such as 135 size is supported by the first support portion, and the first restriction means prevents the film from shifting in the width direction.

Further, a film storage box containing a relatively wide film such as a brownie film is supported by the second support portion and is prevented from shifting in the width direction by the second restriction means. Since the first support part is disposed downstream of the second support part in the film feeding direction, these parts do not interfere with each other.

An embodiment of a film feeding device 10 is shown.

The film supply device 10 for the developing device supplies a 135 size film housed in a cartridge as a first film, or a Brownie size film housed in a film magazine as a second film into the developing device. You can.

Note that FIG. 1 is an enlarged cross-sectional view of a part of the film supply device 10 for a developing device, FIG.
FIG. 3 is a perspective view showing a cassette 18 containing films of the same size as those shown in FIG.

First, a 135 size film is automatically transferred to the developing device 12.
A configuration for feeding a brownie-sized film into the camera will be described first, and then a configuration for manually feeding a brownie-sized film will be described.

As shown in FIG. 6, the 135 size film 14 is housed in a cassette 18 with its front end connected to the leader 1B via an adhesive tape 15.

As shown in FIG. 2.3, the film 14 is housed in the cassette 18 with its leading end connected to the leader 16. The cassette 18 has a box shape, and the cassette body 20
A lid 24 is supported at the upper end of the cassette body 20 via a hinge 22, allowing the inside of the cassette body 20 to be opened and closed. Lid 2
4 closes the interior of the cassette body 20, the interior of the cassette body 20 is shielded from light except for the film supply port 2°A formed at the tip of the cassette body 20. As shown in FIG. 2, this film supply port 2OA is connected to a cylindrical portion 112 which is rotatably supported by the main body 102 and the hebin 104 of the developing device 12.
It is closed by inserting the power set main body 2o.

Inside the cassette body 20, there is a pair of vertical walls 28 at the center in the width direction.
．． 30 is formed along the longitudinal direction. The top surfaces of these vertical walls 28 and 30 are the mounting surfaces for the reader 16, and the distance between them and the side walls 20B and 20C of the cassette body is 135, respectively.
This is a storage space for a cartridge 26 containing a film of the same size.

As shown in FIG. 3, a recess 32 whose height is temporarily reduced is formed in the vertical wall 28.30 near the film supply port 2OA of the cassette body 20, and forms a support surface for the leader 16. ing. That is, the leader 16 is molded from a flexible thin material made of synthetic resin, and maintains a flat state in a free state, so a recess 32 is formed even when it is placed on a vertical wall 28, 30. However, it remains flat. However, when compressive force is applied in the longitudinal direction, it elastically bends and becomes bent along the concave portion 32, so that the vicinity of the tip can be directed diagonally upward compared to the free state.

A gear 34 is rotatably supported by a rotating shaft 54 at one end between the vertical walls 28 and 30, and an endless conveyor belt 36
Engagement protrusions 36A provided at regular intervals on the inner periphery are engaged with a portion thereof. Another part of the inner periphery of the endless conveyor belt 36 is wound around and engaged with a gear 38 disposed between the vertical wall 28, 30 and the cassette rear wall 20D, as shown in FIG. This gear 38 is fixed to a rotating shaft 40, which has brackets 42 and 44 at both ends.
It is pivotally supported to the side walls 20B and 20C of the cassette main body 2o via.

Therefore, the endless conveyor belt 36 is in a parallel state between the gears 34.38, and the engagement protrusions 36B protruding from the outer circumference at regular intervals protrude from the top surface of the vertical wall 28.3o.
It is adapted to engage with the engagement hole 16A of the leader 16 placed on the reader 3o.

A plurality of engagement protrusions 36B protruding toward the outer periphery of the endless conveyor belt 36 are connected to engagement holes 1 formed at regular intervals in the leader 16.
By being inserted into 6A, it is used to drive the reader 16.

A plurality of L-shaped engagement protrusions 46 protrude at regular intervals on the vertical wall 28, 30, into which the film attachment end of the leader 16 can be inserted.

A plurality of gluers 16 are positioned at intervals between these engaging protrusions 46.

Therefore, the ends of the plurality of leaders 16 are connected to the engaging protrusions 4, respectively.
6, and the engagement hole 16A is inserted into the engagement protrusion 36B.
When engaged, the leaders 16 are placed on the standing wall 28, 30 at regular intervals, and the identification lines 16B at the tip are exposed at regular intervals, so the operator can accurately detect the state in which the leaders 16 are attached. be able to.

A pinion 58 (see FIG. 2) is supported via a one-way clutch (not shown) on a rotating shaft 54 to which a gear 34 disposed within the vertical wall 28, 30 is fixed. This one-way clutch transmits only the second clockwise rotation of the pinion 58 as clockwise rotation of the rotary shaft 54 and the endless conveyor belt 36.

As shown in FIG. 2, this pinion 58 is engaged with a rack 62 that is guided so as to be linearly movable within the cassette 18. This rack 62 is connected at one end to a rod 64, and the rod 64 is guided so as to be linearly movable by passing through a guide block 66 attached to the cassette body 20. The tip of the rod 64 is exposed from the film supply port 2OA of the cassette body 20.

Since the rod 64 is biased in the direction of protruding from the film supply port 20A of the cassette body 20 by the biasing force of a compression coil spring (not shown), when the pressing force on the rod 64 is released, the rack 62 returns to its original position. Since the clutch is provided, the pulley 34 does not rotate counterclockwise in FIG. 2.

On the other hand, the rotating shaft 40 of the gear 38 around which the other part of the endless conveyor belt 36 is wound and supported is rotated by a constant angle by moderation means.

As a result, the plurality of leaders 16 come into close contact with each other, and when the leader 16 at the tip receives a tensile force and is sent to the developing device 12, the next leader 16 receives this tensile force due to frictional force and is transported endlessly. Even if a force is generated that causes the belt 36 to rotate inadvertently, the endless conveyor belt 36 is surely prevented from rotating, so that the second leader will not move inadvertently.

The cassette body 20 is provided with a section for attaching the magnet 84,
Further, an adsorption member 86 is attached to the lid 26 in correspondence with the magnet 84.

As shown in FIG.
The supply hole cover 106, which is pivotally supported through the
It has a configuration that covers the supply section 110 for feeding to the second developing section 108.

The supply hole cover 106 has a cylindrical portion 112 as a cassette connection portion.
protrudes obliquely upward, and accommodates the small diameter portions of the cassette body 20 and the lid 24.

The supply section 110 is provided with a locking means 114, and when a developing operation is started with the cassette 18 inserted, an arm 118 engages with the cassette 18 to prevent extraction.
Care is taken to prevent the arm 122 from engaging with the supply hole cover 106 and accidentally opening it. These arms 118, 122 are driven by solenoids 126 controlled by control circuit 130.

Adjacent to these locking means 114 drive means 142 are provided for actuating the rods 64 of the cassette 18. The drive means 142 has a drive rod 144 which is slidable in the axial direction and whose tip end is connected to the rod 6 in the cassette 18.
4, and the other end of this drive rod 144 corresponds to a roller 146.

This roller 146 is connected to the cam 15 rotated by a motor 160.
It can be pushed up at 6.

As shown in FIG. 2, the driving endless belt 162 is wound around a pair of gears 164 and 166 in the supply section 110, and like the endless conveyor belt 36 in the cassette 18, a protrusion 162A protrudes from the inner circumference. It meshes with gears 164 and 166. Further, a protrusion 162B formed on the outer periphery of the driving endless belt 162 engages with an opening 16A of the leader 16 sent out from the cassette 18, and sends out the leader 16 to the developing section 12. Therefore, the driving endless belt 162 is arranged at a position corresponding to the tip end of the leader 16 sent out from the cassette 18.

As shown in FIG. 2, a feeding rubber roller 170 is attached to the central shaft 168 of the gear 166, and serves to feed the film 14 connected to the leader 16.

A pressure roller 174 attached to the supply section lid 106 is brought into contact with this feeding rubber roller 170, so that the film 14 is reliably fed to the developing section 12.

A guide plate 178 is disposed above the gear 164 to ensure that the leader 16 engages with the protrusion 162B of the endless drive belt 162 and to ensure that the film 14 is fed to the rubber roller 170.

Furthermore, a pair of film case support members 92 are arranged on both sides of the gear 164, as shown in FIGS. 4 and 5. These film case support members 92 are fixed to a frame supported by the main body 102.

Since the pair of film case support members 92 have the same structure, only one film case support member 92 will be described.

As shown in FIGS. 1 and 4, the film case support member 92 includes a base 94, a pair of side portions 96 bent in the same direction from both sides of the base 94, and these base portions 94.
and a pair of side portions 96 disposed within the base 9 .
4 and a cartridge support portion 98 integrally formed with the cartridge.

The cartridge support portion 98 is arranged between the pair of side portions 96, and has an arc-shaped first support portion 98A. A part of the outer periphery of the cartridge 26 containing a 135 size film comes into contact with this support portion 98A. Further, a pair of ribs 98B are formed on both sides of the support portion 98A, projecting from the support portion toward the upstream side in the film feeding direction, 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 set to be slightly longer than the film width direction length of the cartridge 26 containing a 135 size film, that is, the width direction length.

Therefore, the cartridge 26, which is supported by contacting the support portion 98A between these lips 98B, is restricted from moving in the axial direction. 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 across the support portion 98A, and have a second support portion 96A formed in a concave arc shape at the tip. This second support part 96A
As shown by imaginary lines in FIG. 5, a part of the outer periphery of the film magazine 100 containing the Brownie film is abutted and supported. This second support part 96
A is on the upstream side in the film feeding direction from the first support portion 98A (
As a result, the support positions of the cartridge containing 135 size films and the film magazine 100 containing Brownie films 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 on this guide portion 96B
is guided by sliding.

Further, the upper portion of the base portion 94 is cut into a rectangular shape to form a film passage groove 94A. The lower portion of the support portion 98A extends downward from the pair of side portions 96, and is provided with a counterbore hole 94.
B is provided so as to penetrate therethrough. A bolt 101 passing through this counterbore hole 94B is screwed into the upper part of the arm plate 132 to connect the arm plate 132 to the film support member 92.

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 space between these guide portions 134 and 136 serves as a guide when the empty cartridge 26 is dropped downward after the film has been taken out.

Further, as shown in FIGS. 4 and 5, a film detector 138 is arranged at the upper part of the film case support member 92, corresponding to the side of the film. This film detector 138 uses a transmission type light detection method that detects the presence of a film by blocking the light emitted from a light emitting element to a light receiving element, or a transmission type light detection method that detects the presence of a film by blocking the light emitted from a light emitting element to a light receiving element. Reflection-type light detection is used, which detects the presence of a film when the light is incident on the film.

When detecting a 135 size film using the film detector 138, since the cartridge 26 is restricted from moving in the film width direction, there is no meandering of the film during film feeding, making it possible to reliably detect a 135 size film. 8 coming.

Furthermore, as shown in FIG. 1, a league detector 140 is disposed above the gear 164.

This reader detector 140 has a contactor 140A and a reader 16
When the reader 16 is transported, the reader 16 swings the contact 140A, thereby detecting the passage of the reader 16.

Further, the league detector 142 is arranged above the gear 166, and a contact 142A is provided to protrude into the conveyance path of the reader 16. Similar to the league detector 140, this league detector 142 also detects passage of the reader 16 by the contact 142A coming into contact with the reader 16.

On the other hand, the cartridge support member 92 is rotatable around a shaft 133 passing through the lower end of the arm plate 132, and the upper part thereof is movable in the direction of contact with and away from the developing section 108, and is normally used for developing with the biasing force of an elastic body. It is pressed in the direction away from the portion 12. However, when all the film 14 in the cartridge 26 is pulled out, the tension acting on the film 14 is reduced to the winding core 14A.
It is possible to approach the developing section 108 by receiving the image through the . This approaching state is detected by a limit switch (not shown), and a signal thereof is sent to the control circuit 130.

3 on the control circuit when this film end state is detected.
A cutter 186 driven by 0 is disposed between the cartridge support plate and the developing section 12. This cutter 18
6 includes an upper blade 188 and a lower blade 190.

In addition, as shown in FIG.
A rotary plate 172 is rotatably supported by a frame (not shown) at the lower part of the rotary plate 2 .

When the supply of each film from inside the cartridge 26 and film magazine 100 is completed, this rotating plate 172 rotates clockwise in FIG.

Next, the Niflow 21 film 128 is transferred to the film feeding device 10.
When inserting the brownie film 128 into the film magazine 100 shown in FIG. The operator inserts the leader 16 between the guided plate 178 and the guide portion 96B and inserts the engagement protrusion 162B into the engagement hole 16A at the top of the leader 16.

Figure 7 shows Brownie Film's film magazine 10.
0 is shown. In this film magazine 100, an inner cylinder 204 is housed in an outer cylinder 202, and these outer cylinders 2
02, the brownie film 128 is accommodated in the inner cylinder 204 in the form of a roll. The outer cylinder 202 has an approximately semicircular peripheral surface, 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 its outer periphery is in contact with the inner periphery of the outer cylinder 202, and end plates 204A are fixed to both ends in the width direction. These end plates 204A
is disposed 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, making the inner cylinder 204 rotatable inside the outer cylinder 202.

Brownie 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 formed 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-out 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 end plate 20
An engaging arm 212 protruding from 2A locks the guide plate 208 to prevent the inner cylinder 204 from being opened inadvertently.

This film magazine 100 has 12 brownie films.
8, the width dimension is larger than that of a commercially available cartridge 26 that accommodates a 135 size film 14. The brownie film 128 is stored in a rolled form and has no core, so its entire length can be drawn out from the film magazine 100.

When the film magazine 100 is in contact with the side portion 96 of the film case support member 92 as shown in FIG. It is fixed to. The four regulating plates 232 are protruded from the rotary plate 172, each facing the film magazine 100,
Movement of the film magazine 100 in the width direction is restricted.

Naturally, the spacing between these regulating plates 232 is wider than the spacing between the side portions 96 of the film case support member 92.

Next, the operation of this embodiment will be explained.

First, the operation of inserting a 135 size film stored in a commercially available cartridge 26 into the film supplying device 10 and supplying the film into the developing device 12 will be described.

As shown in FIG. 6, a plurality of holders 16 are prepared in advance and connected to the film 14 with adhesive tape or the like, and these are attached to the inside of the holder 18 at regular intervals. In this case, the leader 16 sequentially connects the film connecting end to the engaging protrusion 36 starting from the frontmost part.
By this, the identification lines 16B are arranged at regular intervals, so if two readers 16 are arranged one on top of the other or are attached at different intervals, this can be detected and corrected immediately. I can do it.

With the lid 24 closed to the cassette body 20, the small diameter portion of the cassette 18 is inserted into the cylindrical portion 112.

Here, when a development start button (not shown) is operated, the development work begins. When the developing operation is started, the control circuit 130
actuates solenoid 126 so that arm 122 .
118 engages with the supply section lid 106 and the cassette body 20;
Opening of the supply section lid 106 and extraction of the cassette 18 are prevented.

Meanwhile, control circuit 130 drives motor 160, causing eccentric cam 156 to rotate and push rod 64 into cassette 24. This rotational force is transmitted to the rack 62 and rotates the pinion 58. The rotation of the pinion 58 causes the endless conveyor belt 36 to rotate, and the leader 16
6B from the tip of the cassette 24.

As a result, the leading end of the leader 16 comes into contact with the drive endless belt 162 within the supply section 110. In this case, the drive endless belt 162 is rotated at the same speed as the film transport speed in the developing section 108, so its rotation speed is relatively low, and compared to this, the feed speed of the leader 16 is relatively high. Therefore, the leader 10 bends under the compressive force. This bent leader 116, the recess 3 of the vertical wall 28.30
Contact with 2. Therefore, the leader 16 is the driving endless belt 16
The endless conveyor belt 16 is in a state where it is susceptible to the rotational force caused by 2.
The protrusion 162B is bent along the advancing direction of the leader 10 by the rotation of the endless driving belt 162.
The leader 10 is securely engaged with the opening 16 of the developing section 108.
It will be pulled out to.

Furthermore, since the bent leader I6 separates in the thickness direction of the next succeeding leader I6, the engagement opening 16 is deformed and the next leader I6 is bent.
Even when the reader is inserted into the opening of No. 6, it is released and the next reader is not inadvertently subjected to a tensile force.

The dimensional relationship is such that when the leader 16 engages with the drive endless belt 162, the leader 16 is disengaged from the engagement protrusion 36B.

When the leader 16 is pulled out to the developing section 108, the 135 size film 14 and cartridge 26 connected thereto are also pulled out from the cassette 18 and reach the supply section 110. However, the cartridge 26 that has reached the inside of the supply section 110
is the cartridge support portion 92 of the film case support member 92
Since the film comes into contact with the film, movement in the width direction of the film is restricted, and movement to the developing section 108 is stopped. Therefore, the film 14 pulled by the leader 16 is
6 and sent to the developing section 108 where a developing operation is performed.

When this 135 size film is supplied, the cartridge 26 is restricted from moving in the film width direction by the ribs 98B of the cartridge support 898, so the film pulled out from inside the cartridge 26 does not meander. This prevents the film from deviating from the detection range of the film detector 138, so that the film can be detected reliably.

When the entire amount of the film 14 is pulled out from the cartridge 26, the film 14 connected to the end of the winding core 12A is transferred to the developing section 108 via the twenty winding core 12A.
The cartridge support section 98A is pulled toward the developing section 1.
Move in direction 08. This activates the cutter 186 and cuts the end of the film 14. At the same time, the rotary plate 172 rotates clockwise in FIG. 1, and the cartridge 12, whose tensile force has been released, falls inside the supply section 11 and is discharged.

The end of the cut film 14 is the film sensor 138
, the control circuit 130 again drives the motor 160 to raise the drive rod 144 and push the rod 64 upward. Therefore, the next reader 10 is projected into the supply section 110 and the developing operation is performed in the same manner as the previous one.

Next, when the brownie film 128 is to be supplied into the developing device 12, it is stored in the film magazine 100 in the form of a roll. With the leading end of the brownie film pulled out from the film magazine 100 connected to the leader 16, the leader 16 is connected to the guide plate 178 and the guide section 9.
Insert it manually between 6B. In this case, the supply section lid 106 is pivoted upward about the pin 104 as shown by the imaginary line in FIG. 2 to facilitate the insertion of the leader 16 between the guide plate 178 and the endless belt 162. The supply unit lid 106 is returned to its original position to block light. When the cassette 18 is not inserted into the cylindrical portion 112, the tip of the cylindrical portion 112 is closed with a lid (not shown).

Insert the endless belt 16 into the engagement hole 16A at the tip of the leader 16.
When the second engagement protrusion 162B is inserted, the leader 16 is pulled deep into the film supply device 10. As a result, the brownie film 128 receives a tensile force, so that the film magazine 100 comes into contact with the film case support section 96A.

In this state, the brownie film 128 is pulled out from within the film magazine 100 and supplied into the developing device 12. Since the movement of the film magazine 100 in the width direction is restricted by a regulating plate 232 that stands up from the rotating plate 172, it does not shift in the width direction.

Since the brownie film 128 has no winding core in the film magazine 100 and is at the open end, when all of the brownie film 128 in the film magazine 100 is fed into the developing device 12, no tensile force is applied and the rotating plate 172 falls as it rotates clockwise in FIG.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the effect that films having different width dimensions can be reliably guided to the developing device without shifting in the width direction.
