A lid member 53 for opening and closing the cartridge chamber 45 is rotatably mounted on one end face of the first main body 46. On the inner surface of the lid member 53, there are provided a pin 54 that enters the spool 37 of the film cartridge 35 and supports it, and an engaged claw 55 that is locked by a lock mechanism that locks the lid member 53 in a closed state. Is provided. When the lid member 53 is closed, the engaged claw 55 is inserted into a slit 56 formed on the side of the cartridge 45 chamber, and is engaged with the engaging claw arranged in the slit 56.
[0030]
The lock mechanism is operated by an operation lever 58 rotatably mounted on the side surface of the first main body 46, and as shown in FIG. 6, after the lid member 53 is closed, the operation lever 58 is turned counterclockwise in the figure. When the cover member 53 is turned, the engaging claw 60 formed integrally with the operation lever 58 is engaged with the engaged claw 55 to prevent the lid member 53 from being opened.
[0031]
Further, a light-shielding cover drive mechanism for opening and closing the light-shielding cover 41 of the film cartridge 35 by operating the operation lever 58 is driven. A drive lever 63 that reaches the rear end face of the cartridge chamber 45 is mounted on the shaft 62 of the operation lever 58. The drive lever 63 is supported by the rear end face of the cartridge chamber 45 and is connected to the end of the light-shielding lid 41. It is engaged with a connection lever 65 formed integrally with the drive shaft 64 engaged with the portion.
[0032]
Thus, when the film cartridge 35 is loaded in the cartridge chamber 45, the cover member 53 is closed, and then the operation lever 58 is rotated to the lock position (counterclockwise in FIG. 1), the engagement claw 60 is engaged. The claw 55 is locked, and the drive lever 63 is rotated in the same direction as the operation lever 58.

The lock of 53 is released, and the film cartridge 35 can be taken out of the cartridge chamber 45.
[0034]
Further, the lock mechanism cannot perform the unlock operation when the negative film 38 is pulled out from the film cartridge 35 loaded in the cartridge chamber 45. This is because the light blocking cover 41 cannot be turned to the closed position by the negative film 38, so that the turning operation of the operation lever 58 via the connecting lever 65 and the driving lever 63 is prevented.
[0035]
As shown in a cross section in FIG. 7, the film passage 51 has a film passage 67 in which one is connected to the cartridge chamber 45 and the other is connected to the film winding chamber 47. The film passage 67 is formed by plate-like transfer guides 68 and 69 disposed vertically, and exterior plates 70 and 71 of the observation adapter 33 are disposed above and below the upper and lower transfer guides 68 and 69, respectively. ing.
[0036]
Openings 72 and 73 are formed in the upper and lower transport guides 68 and 69, respectively. The opening 73 of the lower transport guide 69 is transparent, and a milky white diffusion plate 74 is fitted into the opening 72 of the upper transport guide 68. I have. Openings 75 and 76 are also formed in the upper and lower exterior plates 70 and 71 at positions facing the diffusion plate 74 and the opening 73, respectively. In the negative film 38 conveyed in the film passage 67, the photographed frames are stopped between the opening 73 and the diffusion plate 74. Then, the negative film 38 is uniformly illuminated by the diffusion plate 74, and the image of the negative film 38 can be viewed through the opening 76 of the lower exterior plate 71 and the opening 73 of the lower transport guide 69.
[0037]
As shown in FIG. 8, a film transport mechanism for transporting the negative film 38 between the film cartridge 35 in the cartridge chamber 45 and the film winding chamber 47 is incorporated in the observation adapter 33. This film transport mechanism includes a take-up shaft 79, a spool drive shaft 80, a motor 81, a drive transmission mechanism 82, and the like.
[0038]
The take-up shaft 79 is rotatably incorporated in the film take-up chamber 47, and is a cylindrical roller provided with a layer of rubber or the like having a high friction coefficient on the outer periphery. The leading end of the negative film 38 that has passed through the film passage 67 is pressed against the outer periphery of the winding shaft 79 by a guide roller (not shown), and is wound by the friction of the surface of the winding shaft 79 that rotates in the winding direction. A gear 86 to which the rotation of the motor 81 is transmitted from the drive transmission mechanism 82 is attached to an end surface of the winding shaft 79.
[0039]
The motor 81 is arranged in a cavity inside the winding shaft 79. The rotating shaft 87 of the motor 81 is provided with a gear 88 protruding from the end face of the winding shaft 79, and the gear 88 transmits the rotating force of the motor 81 to the drive transmitting mechanism 82.
[0040]
The spool drive shaft 80 is engaged with the spool 37 of the film cartridge 35 loaded in the cartridge chamber 45, and the rotation of the motor 81 is transmitted from the drive transmission mechanism 82 to the gear 90 assembled coaxially.
[0041]
The drive transmission mechanism 82 increases the torque of the motor 81 with a plurality of gears and transmits the torque to the winding shaft 79 and the spool drive shaft 80, respectively. Further, the drive transmission mechanism 82 incorporates a one-way clutch that cancels the transmission of rotation to one shaft during film feeding and film rewinding.
[0042]
When the film cartridge 35 is loaded and a predetermined operation is performed, the drive transmission mechanism 82 transmits the rotation of the motor 81 to the gear 86 and the gear 90, and moves the spool drive shaft 80 in the film sending direction to the winding shaft. 79 is rotated in the film winding direction. As a result, the negative film 38 is sent out from the film entrance 40, and is conveyed to the film winding chamber 47 through the film passage 67.
[0043]
The tip of the negative film 38 that has reached the film winding chamber 47 is wound around the outer periphery of a winding shaft 79 that is rotated in the film winding direction. The rotation speed of the take-up shaft 79 is set higher than the rotation speed of the spool drive shaft 80 due to the gear configuration in the drive transmission mechanism 82, so that when the take-up shaft 79 starts winding the negative film 38, the drive The one-way clutch in the transmission mechanism 82 operates, and the spool drive shaft 80 is driven to rotate.
[0044]
Conversely, when the negative film 38 in the film take-up chamber 47 is rewound into the film cartridge 35, the one-way clutch in the drive transmission mechanism 82 operates so that only the spool drive shaft 80 moves in the film take-up direction. Rotated.
[0045]
The observation adapter 33 includes a control circuit 92, a perforation sensor 93 for inputting various detection signals to the control circuit 92, a data plate detection sensor 94, a switch circuit 95, and the like. The control circuit 92 controls the rotation of the motor 81 via a motor driver 96 based on detection signals from a perforation sensor 93, a switch circuit 94, a data plate detection sensor 95, and the like. The battery 48 is connected to the control circuit 92, and power is supplied to the motor 81 and the like via the control circuit 92.
[0046]
The perforation sensor 93 detects perforation of the negative film 38, and for example, a transmission type photoelectric sensor is used. In the negative film 38, perforations 99a and 99b are formed on the leading side and the rear side in the film feeding direction of one frame of the photographed image 98, respectively. A perforation sensor 93 detects these perforations 99a and 99b. The detection signal is input to the control circuit 92.
[0047]
The switch circuit 94 is connected to a button-type one-frame forward switch 101, a reverse-forward switch 102, and a rewind switch 103 provided on the upper surface of the first main body 46. The corresponding signal is input to the control circuit 92.
[0048]
The one-frame feed switch 101 is operated when the negative film 38 is transported by one frame of the photographing screen 98 toward the film winding chamber 47. When the one-frame feed switch 101 is operated, the control circuit 92 drives the motor 81, and rotates the winding shaft 79 in the film winding direction by the drive transmission mechanism 83. During the film transport, the control circuit 92 checks the detection signal from the perforation sensor 93 and stops driving the motor 81 when one frame of the negative film 38 is transported.
[0049]
The one-frame feed switch 101 is also used when feeding the negative film 38 from the film cartridge 35 loaded in the cartridge chamber 45. By operating the single-frame feed switch 101, the negative film 38 sent out from the film cartridge 35 passes through the film passage 67, reaches the film winding chamber 47, and is wound around the winding shaft 79. The control circuit 92 confirms the detection signal from the perforation sensor 93 during this period, and controls so that the first frame of the photographing screen 98 of the negative film 38 is stopped at a predetermined position.
[0050]
The reverse feed switch 102 is operated when transporting the negative film 38 from the film winding chamber 47 to the cartridge chamber 45. While the reverse feed switch 102 is pressed, the control circuit 92 drives the motor 81 to rotate the spool drive shaft 80 in the film rewinding direction by the drive transmission mechanism 83, and moves the negative film 38 into the film cartridge 35. Rewind. Further, the control circuit 92 checks the detection signal from the perforation sensor 93 while the reverse feed switch 102 is being operated. When the operation of the reverse feed switch 102 is released, the control circuit 92 outputs the signal to the last detected perforation 99b. The next shooting screen 98 after the corresponding shooting screen 98 is stopped between the opening 73 and the diffusion plate 74.
[0051]
The rewind switch 103 is used to rewind the entire negative film 38 into the film cartridge 35. When the rewind switch 103 is pressed, the control circuit 92 drives the spool drive shaft 80 in the film winding direction by the motor 81 and the drive transmission mechanism 82, and rewinds the negative film 38 entirely into the film cartridge 35. . When the film is unwound, the transmission of rotation to the winding shaft 79 is released by the one-way clutch, and the winding shaft 79 is driven to rotate.
[0052]
The data plate detection sensor 95 is arranged so as to face the data plate 84 of the film cartridge 35, detects the position of the notch on the data plate 84, and inputs a detection signal to the control circuit 92. As the data plate detection sensor 95, for example, a reflection type photoelectric sensor is used. After the negative film 38 is completely rewound into the film cartridge 35, the control circuit 92 confirms the position of the notch of the data plate 84 by the data plate detection sensor 95, and the display plate 83 of the use display mechanism indicates that the used plate has been used. The spool 37 is stopped at a predetermined position so as to be located behind the mark 43d.
[0053]
Next, the operation of the observation adapter 33 described above will be described. As shown in FIG. 1, the operation lever 58 of the observation adapter 33 is turned to the unlocking side to open the lid member 53. Then, the film cartridge 35 is inserted into the cartridge chamber 45 of the first main body 46 from the axial direction. As a result, the spool drive shaft 80 and the drive shaft 64 are engaged with the ends of the spool 37 and the light shielding cover 41 of the film cartridge 35.
[0054]
After the loading of the film cartridge 35, the cover member 53 is closed, and the operation lever 58 is rotated to the counterclockwise lock side in the drawing. Then, as shown in FIG. 6, the engaged claw 55 of the lid member 53 is locked by the engagement claw 60, and the lid member 53 is locked at the closed position. In conjunction with the locking operation of the operation lever 58, the drive shaft 64 is rotated counterclockwise in the figure via the drive lever 63 and the connection lever 65. Thereby, the light shielding cover 41 is rotated from the closed position shown in FIG. 5 to the open position shown in FIG. 4, and the film entrance 40 is opened.
[0055]
In the image input device 2 in which the observation adapter 33 is set, as shown in FIG. 3, the upper holder 22 of the carrier holder 15 is removed by loosening the screw 28. Further, the image output of the image input device 2 is connected to, for example, a television so that the image of the negative film 38 can be observed. Then, as shown in FIG. 9, the film passage 51 is placed in the recess 23 of the lower holder 21, and the lamp houses 18 and 19 are closed.
[0056]
In this state, even if the lamps 18a and 19a of the lamp houses 18 and 19 are turned on and an image signal is output from the image input device 2 to the television, the negative film 38 has not yet been sent to a position facing the imaging device 77. Therefore, no image is displayed on the television. When the one-frame feed switch 101 of the observation adapter 33 set in the image input device 2 is operated, as shown in FIG. 8, the control circuit 92 drives the motor 81, and the drive transmission mechanism 82 causes the spool drive shaft 80 to rotate the film. It is rotated in the delivery direction. As a result, the leading end of the negative film 38 is sent out of the film cartridge 35 and is conveyed toward the film winding chamber 47 through the film passage 67 shown in FIG.
[0057]
The negative film 38 that has reached the film winding chamber 47 is wound around a winding shaft 79. Thereafter, the spool drive shaft 80 is driven to rotate by the operation of the one-way clutch in the drive transmission mechanism 83, and the winding shaft 79 winds the negative film 38. The control circuit 92 confirms the detection signal from the perforation sensor 93 during this period, and the first frame of the photographing screen 98 of the negative film 38 is stopped at a predetermined position between the opening 73 and the diffusion plate 74. Motor 81 is stopped as described above.
[0058]
As a result, as shown in FIG. 7, the first frame 98 of the negative film 38 is illuminated by the lamps 18 a and 19 a via the opening 75 and the diffusion plate 74, and The image is taken by the imaging device 77, and the image is displayed on the television.
[0059]
When observing another photographed image 98 of the negative film 38, the one-frame feed switch 101 shown in FIG. 1 is pressed. Accordingly, the control circuit 92 drives the motor 81 to rotate the winding shaft 79 in the film winding direction, and the next photographed image is arranged below the diffusion plate 74 based on the detection signal of the perforation sensor 93. . By repeating the operation of the single-frame feed switch 101, the photographed image 98 of the negative film 38 can be sequentially observed from the front end to the rear end.
[0060]

When the rewind switch 103 is operated, the control circuit 92 drives the motor 81 to rotate the spool drive shaft 80 in the film rewinding direction, and rewinds the entire negative film 38 into the film cartridge 35. The data plate detection sensor 95 detects the position of the notch in the data plate 84, and the control circuit 92 confirms the detection signal from the data plate detection sensor 95 and stops the spool 37 at a predetermined position. As a result, the display plate 83 is arranged behind the display mark 43d indicating that development has been completed.
[0064]
Thereafter, by turning the operation lever 58 to the open side, the light-shielding lid 41 of the film cartridge 35 is rotated to the closed position, the lid member 53 is opened, and the removal of the film cartridge 35 from the cartridge chamber 45 is performed. It becomes possible.
[0065]
As shown in FIG. 7, a mark 110 indicating a standard, wide, panorama, or the like is imprinted on the edge of the photographing screen 98 depending on the photographed camera on the negative film 38. The mark 110 can be imaged so that it can be used in later image processing or the like.
[0066]
In the above embodiment, a negative film is used as the developed photographic film stored in the film cartridge. However, a similar effect can be obtained with a positive film. Further, the opening and closing of the light-shielding lid is performed in cooperation with the locking mechanism of the lid member, but may be performed by driving a motor. Further, it is also possible to count the number of perforations during the transport of the negative film, and to find the photographed image of the designated frame number using the magnetic recording data of the negative film. It is also possible to provide a magnetic head for reading magnetic recording data of the negative film in the observation adapter, capture this data with an image input device, and perform color tone correction and the like in accordance with the data. Further, the state where the negative film is pulled out from the film cartridge can be detected by a sensor, and the lid member can be locked.
[0067]
Further, the upper transport guide and the exterior plate constituting the film passage may be all formed of a diffusion plate.
[0068]
【The invention's effect】
As described above, the photographic film image observation adapter of the present invention loads the film cartridge containing the developed photographic film into the cartridge chamber as it is, and uses the film transport mechanism including a motor and the like to transfer the photographic film inside the film cartridge. Since the photo film is transported to and from the film winding room, In a 135-size photographic film observation device, The photographic film in the film cartridge can be easily observed without damaging it. In addition, since the illuminating diffusion plate is provided in the film passage, the photographic film can be uniformly illuminated and an image can be observed with high accuracy.
[0069]
Further, when the photo film is pulled out from the film cartridge in the cartridge chamber, the opening of the cover member of the cartridge chamber is prevented by the lock mechanism, so that the photo film is not damaged. Further, since a battery is used as a power source for the motor, the battery is easy to carry, and the photographic film can be transported by the observation adapter alone. Further, since the operation switch for switching the driving of the film transport mechanism is provided, it is possible to easily observe the images on the front end side and the rear end side of the photographic film.
[0070]
Furthermore, a light-shielding lid drive mechanism for rotating the light-shielding lid of the film cartridge between the open / close position is provided in the cartridge chamber, and this mechanism is driven in association with the opening / closing operation of the lid member of the cartridge chamber. The opening and closing of the light-shielding lid and the lid member can be performed by one operation.
[0071]
Further, after the photo film is rewound from the film take-up chamber, the display mechanism for indicating the use state of the photo film is set to indicate that the photo film has been developed, so that erroneous loading to the camera or the like can be prevented.
