Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a camera, and more particularly to a camera of an easy-to-load film type in which film can be easily loaded.

[Background of the invention]

Loading film in conventional cameras is quite troublesome, and in order to improve this problem, various proposals have been made recently regarding cameras with structures that allow film loading to be made easier than in conventional cameras. The camera and film loading method disclosed in 1999 had the following drawbacks, and therefore had problems in practicality.

For example, in Japanese Patent Application Laid-Open No. 55-143550, there is a film leader that is exposed outside the camera by inserting 9 Torrone into the camera, closing the camera back cover, and locking the back cover. A film-loading camera in which a portion of the camera is cut out] is disclosed. This film loading method makes loading the film easier because it eliminates the need to pull out the film leader section toward the winder and pull it out toward the winder. Since it is necessary to install a cutter etc. on the back cover, there is a possibility of injuring one's hands, creating a new problem in terms of operability of the camera, and the removed film leader section is discarded, which poses the problem of environmental pollution. There was a serious drawback to inviting people.

In addition, Japanese Patent Application Laid-Open No. 57-201221 describes, ``A camera that detects when the film leader part that is pulled out from the cartridge is long and protrudes from the spool chamber and rewinds the film to a position where it fits in the spool chamber. ”
However, in the case of such a film loading type camera, before loading the film, the film leader section is pulled out to the winding gear side, and the film guide provided along the back cover toward the winding gear side is pulled out. There is a drawback that film loading cannot be done quickly because it is necessary to load the film into the cartridge chamber of the camera while guiding the film leader section along the path.Furthermore, nuclear cameras, like conventional cameras, The entire back cover of the camera is designed to open, so when loading film, not only the cartridge chamber but also the spool chamber, pressure plate, etc. are exposed, so the length of the photosensitive part of the film is longer than in conventional cameras. Moreover, for people who are inexperienced with film loading, they may feel anxious about unused film being exposed due to the exposure of the spool chamber, or fear of exposed complex internal mechanisms of the camera. was there. Additionally, since the entire back cover was designed to open, the length of the opening edge of the back cover became long, resulting in poor waterproof performance.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a novel film loading type camera which eliminates the drawbacks of the conventional proposals as described above.

More specifically, it is an object of the present invention to be able to load film into a camera without worrying about the length of the part of the leader exposed from the cartridge, and to also be able to load film into a camera without worrying about the length of the leader part exposed from the cartridge. To provide a camera with a loading system that does not require cutting out the film, a spool chamber that is not exposed when loading film, rapid film loading, and a highly waterproof camera.

[Summary of the invention]

The camera of the present invention has a back cover that is provided on the back side of the camera body and configured so that only the cartridge chamber can be opened, and when the cartridge is inserted into the cartridge chamber and the back cover is closed. A film presence/absence detection means for detecting a film leader portion exposed from the cartridge; a back cover closure detection means for detecting that the back cover is closed; the film presence/absence detection means; and the back cover closure detection means. and control means for driving the film winding and rewinding mechanism to rewind the film leader section into the cartridge when an output is generated from the means. .

In the camera of the present invention having such a structure, only the cartridge chamber is opened on the back side of the camera body, so the shape of the back cover is small, and therefore waterproofness is high. ) Even if the film leader part is long protruding from the cartridge, the film leader part is automatically rewound into the cartridge when the film is loaded, so the length of the film leader part exposed from the cartridge can be adjusted. You can load film without worrying about it at all.

Then, the amount of film feeding can be detected by the feeding switch 54.

Next, the operation of the camera and the operation of each part will be explained.

First, open the back cover 19 as shown in Figure 1 and open the iJ? ) Rone P
is loaded into Nohira Torone chamber a. At this time, the film leader portion F protrudes to the outside of the camera from the film entrance 18 provided between the rear cover 15 and the back cover 19 as shown in FIG.

When the back cover 19 is closed, the hook portion 281 engages with the locking pin 60 and the back cover is locked. The back cover closing signal is detected by a back cover closing detection switch (not shown).

Further, since the film presence/absence detection switch 5 is also pressed by the film leader section F, the film presence/absence detection switch 5
opens and these two switch signals are transmitted to a control circuit (not shown), thereby causing the motor 9 to rotate in the reverse direction. When the motor 9 rotates in the reverse direction as shown in FIG. 4, the sun gear 38 rotates clockwise from the pinion gear 34 via the reduction gears 35 to 37. Accordingly, the planetary lever 39 and the planetary gear 4
1 also rotates clockwise in unison, and the planetary gear 41 meshes with the rewind gear 46. Therefore, the rotation of the motor 9 is transmitted to the fork 51 by the rewind gears 46 to 49 and the fork gear 50. Is the fork 51 I when the back cover is closed?
) Since it protrudes into the roller chamber la, it engages with the mother roller P, so that the film leader section F is rewound.

At this time, since the planetary gear 41 is separated from the intermediate gear 42, the spool 8 and the feeding roller 2 are free.

The end of winding in the film leader section F is detected by turning on the film presence/absence detection switch 5. Therefore, a control circuit (not shown) switches the motor 9 to full normal rotation. Therefore, the sun gear 38 rotates, but the sun gear 38
Since the rotation is counterclockwise, the planet lever 39 is also rotated counterclockwise (14), and the planet gear 41 meshes with the intermediate gear 42.
The intermediate gear 42 is rotated counterclockwise in FIG. Therefore, the friction gear 43 moves clockwise by 1r! After one rotation, the friction gear 44 also rotates clockwise via the spring 45, and the spool 8 rotates counterclockwise, that is, in the film winding direction.

Further, since the Zori 42a located at the upper part of the intermediate gear 42 also rotates counterclockwise, the Day IJ-2b is rotated counterclockwise via the timing belt 52, and the No.IJ-2
The feed roller 2, which is integrated with the film holder b, also works in conjunction with the back cover feed roller 23 to feed the film leader section F to the spool chamber lb side. A. Since the mother char surface is covered with the lath plate 7, the film passes through the gap between the pressure plate 16 and the glass plate 7. At this time, the sprocket 30 and the perforations of the film leader section F automatically mesh with each other.

When the film league part F enters the susol chamber 1b, it is guided by the back cover roller 14 and the main body roller 12 and wound around the spool 8.

The film winding speed of the spool 8 is set to be faster than the film feeding speed of the feeding roller 2, so the film is wound up in the spool chamber 1b without slack, and the difference in speed is determined by the friction gear 43 and friction gear 44. It is absorbed by the spring 45 sliding between the two.

When the film is wound in this manner, the amount of film movement is detected as a pulse signal by the feed switch 54 that is in contact with the A' pulse plate 53 that rotates together with the sprocket 30, and is input to a control circuit (not shown). be done. The control circuit stops the motor 9 when the feed amount equivalent to one frame is detected by the pulse No. 13. Photographing is performed via the photographing lens group 65 of the front plate unit 31. When the number of shots reaches a predetermined number, a signal V is sent from a control circuit (not shown).
Rewinding is automatically performed from this, and the operation of each part during this rewinding is the same as in the case of rewinding the film leader section F described above, in which the motor 9 is reversed and the planetary gear 41 is switched to the rewinding gear 46. This is done by rotating the fork 51 by meshing. Then, when the rewinding is completed, the motor 9 is stopped by a control circuit (not shown).

〔Effect of the invention〕

As explained above, the camera of the present invention has a back cover on the back side of the camera that opens only the Noctrone chamber, making it highly waterproof. You can complete film loading by simply inserting the cartridge into the camera and closing the back cover without worrying about the length, making it extremely easy to operate.Moreover, it is extremely easy to use, and it also prevents film winding failures during film loading and subsequent shooting. It has the great advantage of not causing failure.

Next, the operations for loading film into the camera and taking pictures, and the operations of each part of the camera at that time, will be explained with reference to FIGS. 1 to 6. When loading film, the camera user opens the back cover 19 as shown in FIG. 1, inserts the cartridge P into the cartridge chamber a, and then closes the back cover 19. At this time, the film leader section F is exposed to the outside of the camera through the film entrance 18 formed between the rear cover 15 and the back cover 19, as shown in FIGS. 2 and 3. When the back cover 19 is closed, the hook portion 28 of the back cover opening/closing lever 28
a engages with the locking pin 60, and the back cover 19 is locked. Then, in response to the back cover 19 being closed, the switch 59
is opened, and the electrical signal generated by the operation of this switch 59 is applied to the rewind control circuit 69. On the other hand, since the film leader section F presses one contact piece of the switch 5, the switch 5 is turned off, and an electric signal generated by turning off the switch 5 is inputted to the rewind control circuit 69. When the two signals are input to the rewind control circuit 69, a SASERU control signal is applied from the rewind control circuit 69 to the motor drive circuit 71 to rotate the motor 9 in a reverse direction (rotation in the direction of rewinding the film into the cartridge P). The motor drive circuit 71 supplies a current in the reverse direction to the armature of the motor 9 to rotate the motor 9 in the film rewinding direction. When the motor 9 starts rotating in the film rewinding direction, the sun gear 38 (FIG. 4) is rotated clockwise in FIG. The planetary gear 41 is rotated clockwise.
is meshed with gear 46. Planetary gear 41 to gear 46
When the gears 46 are engaged, the load torque of the gear 46 is greater than the friction between the planetary lever 39 and the J star gear 41, so the planetary gear 41 begins to rotate, and the power of the solar gear 9 is transferred to the sun gear.
38 and the planetary gear 41 to the gear 46 . For this reason, the fork gear 50 is rotated via the gears 46 to 49, so that the fork 51 in threaded engagement with the fork gear 50 descends along the axial direction and enters the center hole of the patrone P, and then the fork 51 is rotated and the film is rewound into the cartridge P. As shown in FIG. 3, the film leader part F exposed outside the camera is drawn into the camera in this way, and the tip of the film leader part F is moved away from contact with the contact piece of the switch 5 to the position of the roller 24. When the switch 5 is reached, the switch 5 is turned on and a signal is applied to the winding control circuit 70 via the rewinding control circuit 69 and the inverter 72. Therefore, while the output of the control signal for reversing the motor 9 from the rewinding control circuit 69 to the motor drive circuit 71 is stopped, the rewinding
A control signal is applied from the 1-stroke control circuit 70 to the motor live circuit 71 to rotate the film 9 forward (rotation in the direction of winding the film onto the spool 8). A current is supplied to the armature in a direction to rotate the motor 9 in the film winding direction. Therefore, the motor 9 starts rotating in the forward direction, and the sun gears 34 to 37
is rotated counterclockwise in FIG. For this reason,
First, when the planetary lever 39 is rotated counterclockwise about the shaft 40, the planetary gear 41 is also rotated counterclockwise about the shaft 40. As a result, planetary gear 4
1 and the gear 46 are disengaged, the planetary gear 41
meshes with gear 42. The planetary gear 41 is then rotated clockwise by the sun gear 38, and the gear 42 is rotated counterclockwise by the planetary gear 41. When the gear 42 is rotated, the pulley 42a integrated with the gear 42 is also rotated counterclockwise, and the pulley 2b is also rotated counterclockwise via the bell 52. For this reason, the feed roller 2 integrated with the pulley 2b is rotated counterclockwise in FIG. 4 and in the clockwise direction in FIG. 3, and the film is fed from left to right in FIG. . On the other hand, since the gear 42 is rotated counterclockwise in FIG. 4, the gear 43 is rotated clockwise, and the rotation of the gear 43 is transmitted to the gear 44 via the spring 45, so that the gear 44 is also rotated in the clockwise direction. be rotated. Therefore, spool gear 8
The spool 8, which is integral with a, is rotated counterclockwise in FIG. 4 (clockwise in FIG. 3). When the feeding roller 2 is rotated in the clockwise direction in FIG. 3, the film begins to move from left to right, and the feeding roller 23 on the back cover side is rotated counterclockwise by the film. Immediately before the motor 9 starts normal rotation, the tip of the film leader is located near the roller 24, so when the feed roller 2 or the feed roller 2 starts rotating clockwise in FIG. It is inserted into the gap between the pressure plate 16 and the glass plate 7, and thereafter passes through the aperture surface along the glass plate 7. When the leading edge of the film reaches the center of the aperture surface, the teeth of sprocket 30 enter the barf of the film, and from then on sprocket 3
0 or will be rotated according to the movement of the film. When the tip of the film leader enters the spool chamber 1b, the film is pressed against the outer peripheral surface of the spool 8 by the roller 14, and further wound around the outer peripheral surface of the spool 8 by the roller 12. Note that the film winding speed of the spool 8 is set faster than the film feeding speed of the feed roller 2, so the film is wound without slack, and the difference in speed between winding and feeding is due to the slippage of the spring 45. It's absorbed. When the sprocket 30 is rotated by the film, the pulse plate 53 also rotates, and the conductor pattern 5 on the pulse plate 53
The switch 54 is turned on and off by the contacts 54a and 54b in contact with the film 3a, and the switch 54 generates a pulse signal corresponding to the movement of the perforations of the film. This pulse signal is input manually to the winding control circuit 70, and is counted by a counter within the circuit 70, and the amount of film feeding (in this case, the amount of empty film winding) is detected and stored. When the amount of winding of the leading end of the film on the spool 8 (i.e., the amount of empty winding) reaches a predetermined length, the winding control circuit 7
0 sends a control signal to the motor drive circuit 71 to stop the motor 9, and in response to the signal, the motor drive circuit 71
cuts off the current supply to the motor 9 and stops the motor 9. For this reason, the camera is set in a shooting standby state with the leading end of the film wound onto the spool 8 for a predetermined length. At this point, the planetary gear 41 of the power transmission mechanism is in the state shown in FIG. 4 in which it meshes with the gear 42. When taking a picture, the photographer presses the camera's release button 57.
When the switch 66 in FIG. 6 is pressed, the switch 66 shown in FIG. 6 is opened and the exposure control circuit 67 is operated, and photometry and exposure (photography) are performed using a known photometer and shutter control mechanism. When the exposure is completed, a signal representing the completion of exposure is sent from the exposure control circuit 67 to the winding control circuit 70, and when the signal is input manually, the winding control circuit 70
"1" causes the motor 9 to generate a rotation amount equal to "piece winding".
A "piece winding up" signal is applied to the motor drive circuit 71. Therefore, the motor drive circuit 71 supplies a current to rotate the motor 9 as much as necessary to feed one frame of film, and the motor 9 is rotated by an amount equal to the amount of feed of one frame of film, and then immediately stops. In this case, power is transmitted from the motor 9 to the spool 8 and the feed roller 2 in the state shown in FIG. Further, the amount of film feeding is detected as pulses generated by contact and non-contact between the contact piece of the switch 54 and the conductive pattern 53a, and the pulses are counted by a counter in the winding control circuit 70. Winding control circuit 7
0 causes the motor drive circuit 71 to stop the rotation of the motor 9 every time a predetermined number of pulses are received from the switch 54. As described above, the film is wound onto the spool 8 by one frame each time the shutter release is released, and when all the frames of the film have been pulled out from the cartridge and have been exposed, the film is transferred to the cartridge P and the spool 8. As a result, a tension detection signal is generated from the tension detection circuit 68, and this signal is applied to the winding control circuit 70 via the rewinding control circuit 69 and the inverter 73. Therefore, the output of the control signal for forward rotation of the motor 9 from the winding control circuit 70 to the motor drive circuit 71 is stopped, while the control signal is manually inputted from the rewinding control circuit 69 to the motor drive circuit 71 and the motor drive circuit 7
1 reverses the motor 9. When the motor 9 is reversed, the planetary gear 41 is engaged with the gear 46 by the same operation as described above, and then the rotation of the motor 9 is transmitted to the fork gear 50 via the gears 46 to 49, and the fork 51 is moved to the patrone P. Once inside, the film is rewound. 2. In the fourth line of page 18, the phrase "This is a perspective view." is corrected to "The perspective view, FIG. 6 is a schematic diagram of the control circuit installed in the camera." 3. "Figure 6" in the drawing will be newly added today.
