Abstract

PROBLEM TO BE SOLVED: To eliminate the need of expressly performing film winding operation with manual labor and to simplify work by automatically winding all the photographic film inside a cartridge by allowing a film winding mechanism to rotate a winding knob in a film winding direction after a film unit is held by a holding mechanism. SOLUTION: When an operation lever 41 is rotated from a position A to a position B, the film unit 1 is held by the holding mechanism and a shutter button is depressed by a shutter depressing mechanism. When the lever 41 is rotated from the position B to a position C further, a cover opening mechanism rotates a hook pawl 42 to the position of a specified insertion angle. When the lever 41 is rotated to the position C, the film winding mechanism rotates the winding knob in a film winding direction. When the lever 41 is separated from the position C, a winding knob mechanism stops the winding of the film. When the lever 41 is rotated to the position B, thereafter, the pawl 42 is inserted in the notched part of the film unit 1 by the cover opening mechanism, and then a bottom cover 23 is opened.

2. Description of the Related Art A film unit with a lens (hereinafter simply referred to as a film unit) is commercially available from the present applicant so that photographers can easily enjoy photography without having to carry a normal camera. The film unit has a built-in photo film with a cartridge in a unit body having a simple photographing mechanism, and the exposed photo film is wound into the cartridge by a film winding operation performed for each photographing, and the photographing is completed. Later, all the photographic films are stored in the cartridge. This cartridge can be taken out by opening a lid provided on the bottom surface. The opening of the lid is performed in a developing laboratory. Then, the film unit from which the cartridge has been taken out is collected at the factory.

[0003] In order to protect the environment and reduce industrial waste, film units are recycled. Resin members and the like used for outer covers and the like are dissolved and recycled into resin pellets. . In addition, the internal parts and the like protected by the outer cover are inspected, and good parts are reused as they are, and defective parts are corrected after correcting defective parts and reused.

[0004]

In a photo lab, there is a case where a film unit is provided in a form in which all the photographic films are not wound in the cartridge. In this case, it is necessary to manually rotate the winding knob in the film winding direction to wind all the photographic films into the cartridge.

When the lid is opened, a screwdriver is inserted into the gap between the lid and the unit body to open the bottom lid. At this time, if the tip of the driver is pushed too far into the back, damage and breakage may occur to the reusable internal parts, and there is a problem that the recycling efficiency is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a first object of the present invention is to simplify the operation of taking out a cartridge at a developing laboratory. A second object is to prevent damage and breakage of internal parts and cartridges.

[0007]

In order to achieve the above-mentioned object, a lid opening device for taking out a cartridge according to the present invention comprises an operating member for performing one reciprocating operation, and a lens utilizing movement of the operating member. A holding mechanism for holding the film unit with the lens in a predetermined posture; and simultaneously or immediately after holding the holding mechanism, a shutter for pressing the shutter button of the film unit with the lens by using the movement of the operation member and maintaining this state. Pressing mechanism: When the operating member reaches the return position of the reciprocating path after the shutter pressing mechanism presses the shutter button, the moving position is detected by the detecting means, and a detection signal obtained from the detecting means is transmitted. A film winding mechanism for rotating the winding knob in the film winding direction only while the film is being wound: after the film winding of the film winding mechanism is stopped. It is obtained by a cover opening mechanism for opening the lid by using the movement of the work member.

[0008] Not all of the film units submitted to a photo lab have the state in which all of the photographic film is rolled into the cartridge. Therefore, all of the photographic film is wound into the cartridge by the film winding mechanism. At this time, in the case of a film unit in which a frame that has not been photographed remains, the film winding stop mechanism operates to prevent film winding. In order to prevent this, a shutter pressing mechanism is provided.

The second pressing plate 57 is attached along the longitudinal direction in the X direction. The second support plate 58 includes two plates 59 and 60. The two plates 59 and 60 are attached at a predetermined distance from each other and along the Y-direction on the surface in the short direction that contacts the bottom surface of the film unit 1. Slide table 6
1 is fixed to the lower surface of the base 43. The second pressing plate 57 projects through the opening of the base 43 to the upper surface. The second support plate 58 is provided on the upper surface of the base 43.

The Y-direction slide table 46 is moved by the interlocking mechanism 62 to move the X-direction slide table 45 to push the second pressing plate 57 against the front of the film unit 1 and to bias the spring 63 therefrom. To move to the retracted position retracted along the Y direction by using.

When the operating lever 41 is operated in the first rotation range, as shown in FIG. 6, the pressing plate 51 and the second pressing plate 57 move to the positions indicated by the two-dot chain lines. As a result, the pressing plate 51 is pressed against the flat surface of the film unit 1, and the bottom surface of the film unit 1 is
9 Further, the second pressing plate 57 is pressed against the grip portion 39 on the front of the film unit 1, and the back of the film unit 1 is brought into contact with the front of the support plate 44.
Therefore, the film unit 1 is moved from two directions and positioned in a predetermined posture.

When the pressing plate 51 moves to the pressing position, the winding roller 54 engages with the winding knob 4 of the film unit 1. The film winding knob mechanism is
A motor 65, a control unit 66, a switch 67, and the like are provided in addition to the above-described winding roller 54. The motor 65 is attached to the X-direction slide table 50 together with the winding roller 54, and when driven, causes the winding roller 54 to rotate the winding knob 4 in the film winding direction.

The driving of the motor 65 is controlled by the control unit 66. The control unit 66 is configured by a simple electric circuit, detects that the operation lever 41 has been rotated to the C position, drives the motor 65, and detects that the operation lever 41 has moved away from the C position. Drive of the motor 65 is stopped.
When the switch 67 is rotated to the position C, the switch piece is pushed by the operation lever 41 to be turned on, and when the operation lever 41 is moved away from the position C, the switch piece is released and turned off.

In this example, the operator recognizes the completion of the film winding through sound and recognizes the completion of the film winding, and then rotates the operation lever 41 from the C position to the A position again to stop the driving of the motor 65.

The shutter pressing mechanism is a hemisphere 68 fixed to the pressing surface of the pressing plate 51, and utilizes the movement of the pressing plate 51 to the pressing position to use the shutter button 7 of the set film unit 1. Press. When the shutter button 7 is pressed, the film unit 1 is in a state in which the operation of the film unwinding mechanism is blocked.

The hook claw 42 of the lid opening mechanism has, for example, the same shape as the tip of a flathead screwdriver, and as shown in FIG.
0. The rod portion 70 is provided so as to be able to move in and out between a projecting position where the hook 42 protrudes from the housing portion 69 and a retracting position where it is retracted therefrom, and is urged by the spring 71 toward the retracting position. The upper part of the rod part 70 protrudes from the housing part 69. In this portion, two pins 72 and 73 protruding in the front-rear direction and a step pin 74 are implanted, respectively.

As shown in FIG.
It is rotatably mounted between the two plates 59 and 60 of the Y-direction slide table section 46. This rotating shaft 75

Is formed with a length corresponding to the second rotation range of the operation lever 41.

On the front surface of the rotating plate 47, two contact plates 7 for transmitting the rotation of the rotating plate 47 to the housing 69 are provided.
6, 77 are provided to protrude forward. The two contact plates 76 and 77 have different lengths in the radial direction of the rotating plate 47, and the contact plate 77 on the forward movement direction side is short and the contact plate 76 on the backward movement direction side is long. When the second pressing plate 57 of the Y-direction slide table portion 46 moves to the pressing position, the tip small-diameter pin 74a enters the rotation locus of the longer hitting plate 76. The longer hitting plate 76 engages with the tip small diameter pin 74a during the forward operation. The shorter contact plate 77 is engaged with the small-diameter pin 77 when the rod portion 70 is in the protruding position and during the backward operation. Therefore, when the operation lever 41 is at the C position, the rod 70 is rotated clockwise from the vertical position shown in FIG. Rotate to the rotated predetermined angular position. When the rod 70 is set at a predetermined angular position, the internal parts of the film unit 1 and the cartridge 1

When the rod portion 70 is set at a predetermined angular position, the large diameter pin 74b at the root of the two-stage pin 74 is
8 enters the rotation locus. The cam plate 78 supports the support plate 44.
The gear 80 is connected to a gear 80 by a connecting shaft 79 rotatably supported by the motor. The gear 80 meshes with a gear portion 47b formed on the periphery of the upper half of the rotating plate 47. Therefore,
The rotation of the operation lever 41 causes the cam plate 78 to rotate. When the operation lever 41 is operated in the third rotation range, the cam plate 78 is configured to push the large-diameter base pin 74b using the rotation force during this operation to move the rod portion 70 to the projecting position. .

When the rod portion 70 moves to the projecting position in the process of operating the operation lever 41 in the third rotation range, the two pins 72, 73 of the rod portion 70 are formed in the grooves formed in the two plates 59, 60. 81 and 82, respectively. These grooves 81 and 82 hold the rod portion 70 at the protruding position during the operation in the remaining third rotation range, and thereafter move the rod portion 70 to the retracted position when the operation lever 41 reaches the B position. Shape. The rod 70
As shown in the figure, the tip small-diameter pin 74a has an opening 44a.
Is biased by a spring 83 in a direction in which it comes into contact with the inner wall on one end side of the, so that it is maintained in a vertical state.

The operation of the following configuration will be described. Device 40
In the initial state, as shown in FIG. 10, the cam roller 52 is in contact with the stopper portion 55a of the rotating plate 47, and the operation lever 41 is in the A position. At this time, the cam surface 55 pushes the cam roller 52 to the left as shown in the figure, and the slide tables 50 and 61 are moved to the retracted positions. The tip small diameter pin 74a is
The spring 83 is in contact with the inner wall on one end side of the opening 44a by the bias of the spring 83. Thereby, the rod part 70
As shown in the drawing, the rotation shaft 75 is in a vertical state with the rotation shaft 75 as the center.

The operator operates the cartridge storage chamber 18
The film unit 1 is inserted from above in a posture in which is set up. This insertion is performed while the back surface of the film unit 1 is along the front surface of the support plate 44 and the bottom surface of the film unit 1 is along the contact surface 59a of the second support plate 59. Thereafter, the operator rotates the operation lever 41 along the forward movement direction (the direction of the arrow shown in the figure). Accordingly, the rotating plate 47 rotates together, and the cam roller 52 follows the cam surface 55, so that the slide table 50 moves in the X direction and the slide table 61 moves in the Y direction.

As shown in FIG. 11, the operation lever 41 is
When the rotation operation is performed to the position, the pressing plate 57 and the second pressing plate 57 are respectively moved to the pressing positions, and the film unit 1 is positioned in a predetermined posture. At this time, the winding roller 54 is engaged with the winding knob 4 of the film unit 1. Further, the hemisphere 68 presses the shutter button 7 of the film unit 1. By pressing the shutter button 7 when the film is wound up, even if the film unit 1 has an unexposed photographing frame, it is possible to prevent the film winding stop mechanism inside the film unit 1 from being broken. can do. It is preferable that the shutter button 7 be pressed before or simultaneously with the winding of the film.

In the process in which the forward operation of the operation lever 41 is continued and the operation lever 41 is rotated in the second rotation range, the longer hitting plate 76 hooks the small-diameter pin 74a at the tip and the spring 83
The rod portion 70 is rotated around the rotation shaft 75 in the same direction against the urging force. And the operation lever 41
Is brought into contact with the stopper 56, so that the state shown in FIG. In this state, the hook 42 is set at the predetermined insertion angle position, and the large-diameter base pin 74b enters the rotation locus of the cam plate 78. In addition, switch 6
7 is turned on, the motor 65 is driven, and the film is wound up.

The operator distinguishes between the sound of winding the film and the sound of winding the film, and recognizes the completion of film winding. After recognizing the completion of film winding, the operation lever 41 is slightly rotated in the backward movement direction (the direction of the arrow shown in FIG. 13), as shown in FIG.
As a result, the switch 67 is turned off and the driving of the motor 65 is stopped.

Further, the cam plate 78 rotates in conjunction with this slight rotation operation, and the root large diameter pin 74b is pushed by a displacement corresponding to this rotation. Accordingly, the rod portion 70 is moved toward the projecting position against the bias of the spring 71, and the hooking claw 42 is projected. When the rod 70 moves to the projecting position, the two pins 72 and 73 are inserted into the grooves 81 and 82, respectively.
In addition, the tip small diameter pin 74a enters between the contact plates 76 and 77, respectively. In addition, at this time, since the film unit 1 is still held by the holding mechanism, the hooking claw 42 penetrates the exterior body 3 and is inserted into the notch 39. The insertion at this time depends on the displacement of the cam plate 78 and 2
By managing the positions where the pins 72, 73 enter the grooves 81, 82, damage to the internal components of the film unit 1 can be reliably prevented.

When the operation lever 41 is subsequently operated backward,
The shorter contact plate 77 in the third rotation range is
4a is pressed in the same direction as the rotation operation. During this time, since the two pins 72 and 73 move along the grooves 81 and 82,
The rod 70 rotates while being held at the protruding position.
By this rotation, the hook 42 is moved to the film unit 1.
14, and the bottom cover 23 is opened as shown in FIG. 14. At this time, a cutout 59b is provided below the contact surface 59a of the two plates 59 by the opening space of the bottom cover 23.

When the operating lever 41 is operated to the position B, the two pins 72, 73 are disengaged from the grooves 81, 82, and the rod portion 70 returns to the retracted position by the bias of the spring 71, and the small-diameter pin 74a at the distal end is moved. The small diameter pin 74a comes out of the contact plate 77 and comes into contact with the inner wall at one end of the opening 74a. As a result, the rod portion 70 does not follow the subsequent return operation of the operation lever 41. Finally, when the operating lever 41 is returned to the position A, the holding mechanism releases the holding of the film unit 1 by the displacement of the cam surface 55 during this time.

When the bottom cover 23 is opened, the locking pawls 25 and 26 or the inner wall of the front cover 13 is bent, and the locking of the film unit 1 with the inner wall of the front cover 13 is released. And
When the connection rod 35 is further opened, the connection rod 35 is moved toward the lowered position by the engagement between the locking claw 36 of the bottom cover 23 and the lower end 35b of the connection rod 35, and the upper end 35a of the connection rod 35 is
4 is withdrawn from the rotation locus.

Thus, the drive shaft 34 is rotated by the bias of the spring 33, and the cover member 31 of the cartridge 17 is closed. Thereafter, the engagement between the locking claw 36 of the bottom cover 23 and the lower end 35b of the connection bar 35 is released, and only the bottom cover 23 is opened while leaving the connection bar 35 at the lowered position. At this time, the exterior body 3
Is broken along the perforation by opening the bottom cover 23, so that the opening operation of the bottom cover 23 is not hindered. Also,
When the engagement between the locking claw 36 of the bottom cover 23 and the lower end 35b of the connecting rod 35 is released, for example, even if the locking claw 36 is broken, the film unit 1 is set up with the cartridge storage chamber 18 down. Since it is set in the state of being folded, there is no inconvenience that the damaged locking claw 36 falls directly under the device 40 and remains inside the film unit 1.

When the film unit 1 is taken out of the apparatus 40, the bottom cover 23 of the film unit 1 is in an open state, so that the cartridge 17 containing the photographed photo film 19 from the cartridge storage chamber 18 can be easily removed. Can be taken out.

In the above embodiment, the apparatus used in the film unit 1 in which the photo film cartridge 16 of the type in which the photo film 19 is sent out by rotating the spool is previously described. However, the present invention is not limited to this. It is needless to say that the present invention can also be used for a film unit incorporating the photographic film cartridge. Further, the lid opening mechanism is not limited to using a hook claw.

Further, although the lid for taking out the cartridge is a pull-top type lid, the present invention is not limited to this.
For example, a slide-type lid may be used. In this case, after the hook is inserted into the end of the lid, the lid can be easily opened simply by linearly moving along the direction toward the opening position.

The film unit 1 of the above embodiment has
There is a type in which the winding knob 4 is locked after the entire photo film 19 is wound into the cartridge 17. In this case, the drive of the motor 65 may be stopped by detecting the load on the motor 65 caused by the lock on the winding knob 4 by the detecting means.

Although the operation lever 41 of the above embodiment is of a reciprocating rotary operation type, the present invention is not limited to this, and may be a type of reciprocating linear operation.

[0055]

As described above, in the opening device for taking out a cartridge according to the present invention, after the film unit is held by the holding mechanism, the film winding mechanism rotates the winding knob in the film winding direction to move the photographic film into the cartridge. Since the film is automatically wound into the inside, as described in the related art, it is not necessary to manually perform the film winding operation, and the operation is simplified. Moreover, since the holding mechanism and the lid opening mechanism are operated by using the movement of the one reciprocating operation of the operating member, the holding mechanism and the lid opening mechanism are operated by using, for example, a drive source such as a motor. Can be made at low cost.

According to the second aspect of the present invention, since the holding means for holding the lens-fitted film unit in an upright position with the cartridge storage chamber facing down is provided, for example, a locking claw or the like is used when the lid is opened. Even if the parts are damaged, the damaged parts fall downward, so that it is possible to reliably prevent the inconvenience of remaining inside the film unit and causing trouble during recycling.

According to the third aspect of the present invention, since the lid opening mechanism is a mechanism for hooking a hook on an end of the lid and opening the same, the tip of a driver or the like is pushed too far into the back as described in the prior art. As a result, the inconvenience of damaging or damaging the internal parts and the like can be reliably prevented, and the reliability is improved as compared with manual operation.
