Abstract

PURPOSE:To visually confirm film loading to freely photograph without feeling anxiety about presence/absence of a film by detecting a film with a switch provided in a film entrance to reduce the idle rewinding speed. CONSTITUTION:When a rear cover is closed with a film leader part F being remained outside, a switch 300 is closed, and contact pieces 303c and 303b of a rewind mode discriminating switch 303 are brought into contact with each other, and a motor 9 is rotated in the rewinding direction at a low speed because a half of the overall voltage is applied to the motor 9. The front end of the wounded-in leader part is detected by a switch 5 to release contacting between a contact piece 5a and the film, and the motor 9 is rotated in the winding direction at a regular speed because the overall voltage is applied to the motor 9 by contacting between contact pieces 303a and 303c. Since a photographer can visually confirm film loading by slow rotation of the motor, he photographs without feeling anxiety about presence/absence of the film.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a camera that allows film loading to be carried out much more easily than in conventional cameras, and which is also much more waterproof than conventional cameras. Ru.

[Background of the invention]

In conventional cameras, loading film is quite troublesome, and to improve this problem, a number of proposals have recently been made for cameras that allow film loading to be performed more easily than in conventional cameras.

Both the present applicant and conventional camera engineers have already proposed a simple loading type camera that can extremely easily load film, and according to this proposal, it is possible to load film extremely easily. Not only that, but it has also been shown that it is possible to create a camera that is more waterproof than conventional cameras.

The easy-to-load film camera proposed by the applicant has an extremely small back cover that can only open the cartridge chamber and the cartridge chamber. After that, if you close the back cover with the film leader section exposed to the outside of the camera, the film leader section will be automatically drawn into the camera, and then the film will be automatically wound inside the camera and ready for shooting. It had a structure in which the camera was automatically set.

Therefore, the camera proposed by the present applicant has the advantage of being superior in waterproofness and robustness to conventional cameras, as well as being extremely easy to load film, but this camera has the following features: There were still some issues that needed to be improved.

That is, in the above-mentioned camera, the rewinding speed is high during so-called idle rewinding when the film leader section exposed outside the camera is drawn into the camera, so that the film leader section is instantly drawn into the camera. There is a problem in that camera users cannot remember clearly whether or not they have loaded the film, and are more likely to feel anxious about loading the film. In addition, unlike conventional cameras, the user does not set the film leader inside the camera at all, so it is up to the user to determine whether or not the film leader inside the camera has been set correctly. The problem is that it tends to induce anxiety.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned problems inherent in the above-mentioned camera already proposed by the present applicant, and to provide an improved film loading type that does not cause the user to feel uneasy. By providing the camera.

[Summary of the invention]

This invention makes the speed at which the film leader is pulled into the camera during film loading slower than the normal film rewinding speed, so that the camera user is not sufficiently guided by the film leader into the camera. The camera is visually recognized, and is characterized in that it does not make the user of the camera feel uneasy as described above.

That is, in the camera of the present invention, the presence of the film leader section in the film entrance formed on the closed surface of the back cover is detected, and in response to the detection operation, the film winding and rewinding mechanism f: is controlled to a low speed. The present invention is characterized in that it is equipped with a film leader section rewind control means. The film leader section rewind control means shown in the following embodiments comprises at least one switch provided in the circuit of the drive motor of the film winding and rewinding mechanism, and the switch also It also serves as film leader detection means for detecting the film leader at the entrance.

Although the structure disclosed above is the same as the structure of the camera of the earlier invention by the present applicant, the improved camera according to the present invention is also constructed by adding the basic device to the camera of the earlier invention. The explanation has been made for understanding of the present invention.

A feature of the present invention is that the camera is provided with a film leader section rewinding control means for allowing the camera user to sufficiently visually confirm the rewinding state of the film leader section F when loading the film.

Embodiments of the film leader section rewind control means, which constitute the essential part of the present invention, will be described below with reference to FIGS. 1 to 7.

1 and 2 are diagrams showing a second embodiment of the film leader section rewind control means. In FIG. 1, 5 is the film leader detection switch described above, and the film leader detection switch 5 is used together with the rewind mode discrimination switch 303 also shown in FIG. 1 and the back cover closing detection switch 300 shown in FIG. It is incorporated into the main circuit of the film winding and rewinding motor 9. The film leader detection switch 5 is fixed to the rear cover 15 (see FIG. 10), and one of the two contact pieces 5
a is in contact with the film leader sF, and only when the film leader part F is at the film entrance 18 as shown in FIG. pushed by

and.

In this way, when the contact piece 5a is cut off from the other contact piece by the film leader section F, the switch 51I-f
It is configured to be turned on and turned off when one contact piece 5a comes into contact with the other contact piece (that is, when the film leader part F is no longer present in the film entrance 18).

FIG. 2 shows a back cover closing detection switch 300 built into the motor 9 and its main circuit. Film leader detection switch 5
1 shows a connection diagram of the rewind mode discrimination switch 30λ, the winding and rewinding operation switch 4, and the power source 3.

When the film leader part F is in the film entrance port 18 as shown in FIGS. 9 and 10, the winding loss mode determination switch 303 contacts the contact piece 303c and the contact piece 303b to short-circuit half of the power supply 3. On the other hand, film leader YAF
The tip of is from the film entrance 18 to yJJ2 back cover Romura 2.
When pulled in to position 4, contact piece 303c and contact piece 3
03& are designed to make contact.

Further, in FIG. 2, a switch 302 is a switch that is opened and closed by a control circuit (not shown), and is a stop switch that responds to the amount of film feeding and the motor rotation lid.

The winding and rewinding operation switch 4 is a switch that is automatically switched by a control circuit (not shown) when winding and rewinding the film, and when rewinding, the contact 4aK is closed as shown by the solid line in FIG. During winding, it is a Guyang type switch that is connected to the contact 4b as shown by the dotted line in the figure.

The operation and operation of each part of the camera of the present invention will be explained below with reference to FIGS. 1, 2, and 8 to 11.

First, open the back cover 19 as shown in FIG. 8, and load the cartridge P into the cartridge chamber la as shown in FIG. At this time, the film leader portion Fi protrudes to the outside of the camera from a film inlet 18 provided between the rear cover 15 and the back cover 19, as shown in FIG. In addition.

When the back cover 19 is open and the cartridge P is not loaded, the back cover close detection switch 300 is open in FIG. 2, and the winding and rewinding operation switches 4 are open.
The Vi contact 4a is closed (rewind state), and the contact piece 303e of the rewind mode discrimination switch 303 is in contact with the contact piece 303a. Also.

Film leader section detection switch 5 is open and switch 3 is open.
02 is closed.

When the back cover 19 is closed, the hook portion 28a shown in FIG. 12 engages with the locking pin 60, and the back cover is locked. Therefore, the back cover closing detection switch 300 is closed in FIG. The contact pieces 303c and 303b come into contact, and the full voltage of the power supply 3 is applied to the terminals of the motor 9 by the circuit shown by the solid line in FIG. 2, and the motor 9 rotates in the reverse direction (rotation in the rewinding direction). be done. In this case, since a voltage lower than the normal operating voltage is applied to the motor 9, the motor 9 rotates in the rewinding direction at a low speed even during normal rewinding operation.

When the motor rotates in the reverse direction in FIG. 11, the sun gear 38 rotates clockwise from the pinion gear 34 via the reduction gears 35 to 37. Correspondingly, the planetary lever 39 and the planetary gear 41 also rotate clockwise in unison, and the planetary gear 41 meshes with the rewinding gear 46. Therefore, the rotation of the motor is transmitted to the fork 51 by the rewind gears 46 to 49 and the fork gear 50. When the back cover is closed, the fork 51 protrudes into the cartridge chamber la and engages the nosotrone P.9. Therefore, 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.

In addition, in this case, as mentioned above, the rotational speed of the motor 9 is much slower than in the case of continuous rewinding, so the film leader section F disappears from outside the camera to the inside of the back cover 19 at a slow speed. As a result, @Ministry of Shadows can fully see the fact that the film is loaded.

When the tip of the film leader section F is pulled into the camera and reaches the position of the second back cover roller 24, there is no contact between the contact piece 5a of the film leader section detection switch 5 and the film leader section F, so as shown in FIG. The switch 5 opens and the force with which the film leader section F presses the contact piece 303c of the rewind mode discrimination switch 303 decreases, so that the contact piece 303c contacts the contact piece 303a and the contact piece 303b
move away from At the same time, the switch 302 is opened in response to the switching operation of the switch 303.

As a result, the connection between the motor 9 and the power supply 3 is cut off, and after the motor 9 temporarily stops, the winding and rewinding operation switch 4 is switched from the contact 4a to the contact 4b by a control circuit (not shown). After the switches 4 and 5 and 303 are switched to the positions indicated by the dotted lines in FIG. 2, the switch 302 is turned on and the full voltage of the power supply 3 is applied to the motor 9 in its normal rotation direction. As a result, the motor 9 rotates forward at the normal hoisting speed, and the rotation is caused by gears 34 to 37 in FIG.
is transmitted to the sun gear 38 via.

Therefore, the sun gear 38 rotates, but since the rotation of the thick 1m-f gear 38 is counterclockwise, the planetary lever 39 is also rotated counterclockwise, and the planetary gear 41 meshes with the intermediate gear 42. Otherwise, the intermediate gear 42 is rotated counterclockwise in FIG. Therefore, the friction gear 43 rotates clockwise, the friction gear 44 also rotates clockwise via the spring 45, and the spool 8 rotates counterclockwise, that is, in the film winding direction. Boo! Since the J-42a also rotates counterclockwise, the Goo IJ-2b is rotated counterclockwise via the timing belt 52, and the Goo IJ
- The feeding roller 2 integrated with 2b is also the back cover feeding roller 23.
In conjunction with this, the film leader section F is sent out to the spool chamber side. Since the 4-char surface is covered with the glass 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 perforation part of the film leader section F automatically mesh with each other. When the film leader section F enters the spool chamber lb, the back cover roller 1
41 is guided by the main body roller 12 and wound around the spool 8.

Furthermore, since the film winding speed of the spool 8 is set faster than the film feeding speed of the feeding roller 2, the film is loaded in the stool chamber 1b without sagging, and the difference in speed is determined by the friction gear 43 and friction. This is absorbed by the spring 45 sliding between it and the gear 44.

When the film is wound in this manner, the movement of the film is detected by the feed switch 54, which is in contact with the Nockles plate 53 that rotates together with the sprocket 30, as an error signal, and a control 641 (not shown) is detected. input to the circuit. The control circuit opens the switch 302fc in FIG. 2 to stop the motor 9 when the Noyalus (g) has reached the feed level equivalent to one frame. Photographing is performed through the lens of the front plate unit 31.

When the number of captured images reaches a predetermined number, rewinding is performed dynamically in response to a signal from a control circuit (not shown).

At this time, rewinding is different from the above-described blank rewinding of the film leader section F, and since normal rewinding is possible, a signal from a control circuit (not shown) is activated to switch the winding and rewinding operation switch shown in FIG. 4 is simply switched from contact 4b to 4a, switch 5 and switch 303 are held in the dotted line position in FIG.

Therefore, the motor 9 rotates with the full voltage of the F'im source 3 applied thereto.

The embodiment shown in FIG. 3 is different from the above-mentioned embodiments in that when the film leader section F starts rewinding, it rewinds at the normal rewinding speed, but from the middle it slows down and rewinds the film. The purpose is to return the motor and obtain a motor stop signal.

In Figure 3, a switch 311 is a switch that detects the passage of the upper edge Fa of the film IJ-GOO gF, and a switch 310 is a switch that detects the passage of the lower edge Fb of the film leader section F. The control function of the switch 311 is to reduce the rotational speed (that is, the applied voltage) of the motor 9 when the passage of the upper edge Fa of the film leader section F is detected. The motor 9 is stopped when the passage of the lower edge rb of F is detected.

FIG. 4 is a schematic diagram of a motor main circuit having both the switches 310 and 311, and in this figure, parts designated by the same reference numerals as in FIG. 2 are the same as the nine parts already described.

In the camera of this embodiment, which has the film leader section rewind control means configured as shown in FIG. 3 and FIG.
When the back tray 19 is closed while remaining outside the camera, the film leader section F is moved to the contact piece 31 of the switch 311 in FIG.
1a and the contact piece 310a of the switch 310 toward the front (that is, in the direction away from the contact pieces 311b and 310b).
4, the full voltage application contact A of switch 3txhx source 3 is closed, while switch 310 is closed. Since the back cover closing detection switch 300 is also closed at the same time as the back cover 19 is closed, the full voltage of the power supply 3 is applied to the motor 9, and the motor 9 rewinds the film at the normal rewinding speed. Rotate to . (Explanation of the movement of gears inside the camera, etc. will be omitted.) For this reason, the film leader F, which had been protruding outside the camera, moves into the camera at high speed, but the upper edge Fa of the film leader F After passing through the point of contact with the contact piece 311a of the switch 311, the external force that separates the contact piece 311a from the contact piece 311b disappears, so in FIG. As a result, motor 9
The voltage applied to the film leader F is reduced, the motor speed is reduced, and the film leader section F is rewound at a low speed. When the lower edge Fb of the film leader part F passes the tip of the contact piece 310a of the switch 310, the external force that separates the contact piece 310a from the contact piece 310b disappears, so that the switch 310 in FIG. When it is opened, the power supply to the motor 9 is cut off, and the rewinding of the film leader section F is completed.

The embodiment shown in FIG. 5 uses the switch 31 shown in the previous embodiment.
It is equipped with a δ inch 320 at the 0 position. The switch 320 is provided in a control circuit separate from the main circuit of the motor 9, and is electrically connected to the counter.

Further, the counter is configured to control a switch in the raw circuit of the motor 9, and each time the tip of the contact piece 320a slips into the perforation a/324 of the film, an input signal to the counter is generated. Occur. The counting operation of the counter is started by pressing the contact piece 311a of the switch 311.
When the tip of the counter passes the upper end of the film leader section F, [Fa passes, and when the counter counts a predetermined number of human pulses, a switch controlled by the counter is opened and the motor 9 The main circuit is opened.

Therefore, when the cartridge is loaded into the camera and the back cover is closed as described above, the full voltage of the power supply 3 is applied to the sleeve 9, and the film reader is exposed outside the camera, as in the previous embodiment. The film is rewound in the direction of the arrow in FIG. 5 at a normal rewinding speed, but the upper edge Fa of the film leader
When the film passes through the tip of the contact piece 311a of the switch 311, the switch 311 is switched to the first position and the voltage applied to the motor 9 is reduced, so that rewinding is performed at a low speed from this point on. At this time, the familiarization switch 311
The switching signal of the counter becomes a signal to start the operation of the counter, and from that time on, the electrical signal generated by the contact piece 320a of the switch 320 falling into the perforation 324 of the film starts the operation of the counter. Enter. Then, when a predetermined number of pulse signals are received, the counter opens the switch of the main circuit of the motor 9, and the motor 9 is stopped.

In the embodiments shown in FIGS. 3 and 5, the rewinding speed of the film leader section is not slowed down even υ compared to the normal rewinding speed throughout the entire rewinding process, and the mL Therefore, the time required for winding the film leader section is shortened in the embodiment shown in FIG. 1, and there is no risk of irritating the camera user.

In the embodiment shown in FIG. 6, two switches 320 and 330 are provided which emit electrical pulse signals falling into the motherfoils 324 and 325 (above and below the film), these switches being identical. It is connected to a counter which operates to open a switch in the main circuit of motor 9 when one of the input voltages from both switches 4 is absent. Upper and lower perforation eyes 324
Since the contacts 325 are lined up in a straight line in the width direction of the film, when the switch 330 is no longer input to the counter, the upper edge F& of the film leader section F is located at the tip of the contact piece 330a of the switch. The passage is detected by the counter. When the upper edge Fa of the film leader section F passes the tip of the contact piece 330a of the switch 330, the counter lowers the voltage applied to the motor 9 to rotate the motor at a low speed. The film leader section is rewound. At the same time, the pulses generated from the switch 320 are counted by the counter.

When a predetermined count is reached, the power supply to the motor 9 is stopped and the rewinding of the film leader section is completed. In this case, the power supply to the motor 9 is stopped by detecting the count number of the four-foreign seal 324 on the lower side of the film, so that the lower edge Fb of the film leader part It never comes to the left.

The embodiment shown in FIG. 7 is an embodiment in which the rewinding is performed at a lower speed than the winding. The present invention is characterized by providing gear trains 91 to 96 with larger sizes. Note that this embodiment is also provided with a film leader detection switch 5, as in the other embodiments.

〔Effect of the invention〕

As shown in the above embodiments, the camera of the present invention is provided with a control means for slowing down the rewinding speed when the film leader section is unwinded, so that the film leader section can be moved relatively slowly. The camera user can clearly see that the object is being drawn into the camera at a certain speed.
Therefore, there is no possibility that the camera user will have doubts as to whether or not the film has been loaded, and the present invention can provide a camera that is easier to handle.
