Abstract

PURPOSE:To prevent the futile photographing of a film caused by the unwanted depressing of a shutter button by breaking wiring between a winder and a battery and housing a film unit with a lens in a package bag in a state just after the releasing of a shutter is completed. CONSTITUTION:The base part of a unit main body 3 incorporates the winder for taking up the film linked with the release of the shutter, the battery being the power supply of the winder and a main switch 7 turning on and off the supply of the power to the winder arranged in the battery and the winder. After the functions of a shutter mechanism, etc., are inspected, an outer case 4 is fitted into the unit main body 3 so that the film unit with the lens 2 is obtained and housed in the package bag, to be shipped. At this time, the wiring between the winder and the battery is broken and the shutter is released to house the film unit 2 in the package bag in this state. Therefore, even if the shutter button 6 is depressed by a vibration and an impact at the time of carrying and when the package bag is unsealed, the shutter is never released and the film is never taken up as well.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens-fitted film unit, and more particularly to a lens-fitted film unit incorporating a winder and a method for manufacturing the same.

[0002]

2. Description of the Related Art The applicant of the present invention also provides a lens-fitted photo film unit (trade name "Sharan", which can be easily taken without taking a camera with the camera). This lens-fitted photo film unit is inexpensive and excellent in portability, and has a structure in which a photographing mechanism such as a shutter mechanism is incorporated in a unit main body in which the photo film is built in advance. After shooting, the winding knob is rotated to wind up the film that has been shot into the cartridge, and shutter charging is performed in tandem with this winding operation to prepare for the next shooting.

In such a film unit with a lens, a winder is built in the unit body as in Japanese Patent Application No. 5-325256 and Japanese Patent Application No. 5-325258, and the motor of the winder is It has been proposed that a film that has been photographed can be wound up in a cartridge by rotating it. According to the present invention, since the film is automatically wound after photographing, it is possible to prevent the film winding operation from being forgotten and the shutter chance being missed.

A winder built into a general compact camera presses a shutter button, and when the shutter button is released, the motor is rotated to wind a film of a photographed film on a film winding shaft. 1 film
The motor is designed to be stopped when the frame is wound. Further, the shutter button is locked by turning off the main switch when not in use, thereby preventing unnecessary photographing. The same applies to the film unit with a lens with a built-in winder, and the motor is rotated by pressing the shutter button and releasing the shutter button to wind the filmed film into the cartridge. Then, when the film having been photographed is wound up by one frame, the motor is stopped.

[0005]

As described above, the lens-fitted film unit is superior to general cameras in that it is inexpensive and has good portability, and when the winder is built in, it is low-cost and compact. Things are desired. Therefore, it is difficult to add a function of locking the shutter button by turning off the main switch like a compact camera. Also, the lens-fitted film unit is sold in a moisture-proof packaging bag, but without the mechanism for locking the shutter button as described above,
It is conceivable that the shutter button is pressed from the top of the packaging bag due to vibrations or shocks during transportation, and the film is wound up, and the film is wasted for several frames. Further, a user who purchases the lens-fitted film unit may erroneously press the shutter button when taking out the lens-fitted film unit from the packaging bag, which may also waste the film.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a film unit with a lens with a built-in winder and a method for manufacturing the same, which prevents unnecessary film photographing of the film due to unnecessary pressing of a shutter button. .

[0007]

In order to solve the above problems, the invention according to claim 1 cuts off the wiring between the winder and the battery of the film unit with a lens with a built-in winder and immediately after the shutter release. It is designed to be stored in a packaging bag in this state.

According to the second aspect of the present invention, when the lens-fitted film unit is used, the interruption of the wiring of the winder is released. Further claim 3
In the invention described above, the film is wound one frame and the shutter is charged after the interruption of the wiring of the winder is released.

In a fourth aspect of the present invention, as a method of manufacturing a film unit with a lens with a built-in winder, a first step of bringing a shutter mechanism incorporated in a main body base into a state immediately before shutter charging, a loading of a film, and a rear loading of the film are performed. The second step of attaching the cover, the third step of turning off the main switch, the fourth step of setting the battery, and the fifth step of turning on the main switch to perform the film winding test.
The process and the sixth process of performing a shutter test by turning off the main switch and performing a shutter release are performed.

[0010]

The film unit with a lens with a built-in winder is manufactured by winding the film winder on the base of the main body in conjunction with the shutter release, the battery serving as the power source for the winder, and the winder arranged between the battery and the winder. A main switch for turning on / off the power supply is incorporated.

After that, a first step for setting the shutter mechanism to a state just before the shutter charge, a second step for loading the film and a rear cover, a third step for turning off the main switch, and a battery are set. And a fifth step of turning on the main switch to perform a film winding test, and a sixth step of turning off the main switch to perform shutter release to perform a shutter test.
It is shipped in a packaging bag.

In the shipped film unit with a built-in winder lens, even if the shutter button is pressed from the top of the packaging bag due to vibration or shock during transportation, the main switch is turned off and the wiring is cut off. Since the state is immediately after the end, the shutter release and the film are not newly wound and the film is not wasted. Further, when the film unit with a lens with a built-in winder is used, turning off the main switch releases the disconnection of the wiring, and the film is wound up by one frame and the shutter is charged to enable photographing.

As shown in FIG. 4, the lower gear 51a of the gear 51 constituting the gear train 32 transmits the winding gear 61 to the winding gear 61, and the winding gear 61 is rotated counterclockwise in FIG.

The rotation of the winding gear 61 is transmitted to the spool 21d of the cartridge 21a shown in FIG. 3 by the tooth row 63a of the drive shaft 63, and the film 21b is rotated by the cartridge 21a.
It is wound up in a. As a result, the driven sprocket 95
Is rotated, and this rotation is transmitted to the rotating member 94. The rotation of the rotating member 94 causes the shutter charge cam 94b to rotate.
The shutter drive lever 90, of which one end 90b is in contact with, is rotated clockwise against the bias of the spring 92 to move to the charge position. Further, the claw portion 74b of the locking lever 74 is inserted into the groove 94e of the unwinding cam 94a to lock the rotation of the driven sprocket 95. Further, the engagement of the groove 94e and the claw portion 74b causes the locking lever 74 to slightly rotate in the clockwise direction, so that the protruding portion 74c and the rising piece 90c.
And are engaged and shutter charging is performed.

At the same time, when the locking lever 74 is rotated clockwise, the engaging portion 72 is pushed by the pin 75 of the locking lever 74 shown in FIG. 4, and the switching lever 69 is rotated counterclockwise. It This switching lever 69

6 is pressed to the back side to deform the first contact piece 79 and bring it into contact with the contact portion 83a of the third contact piece 83 as shown in FIG.
As a result, the motor 31 is short-circuited and the motor 3
The rotation of 1 is stopped.

Since the exposure unit 14 was in the state immediately before the shutter was charged by rotating the driven sprocket 95, the film winding operation ends immediately, but by using this, the film winding and the film winding are performed. Inspect motor stop due to termination. The unit body 3 that fails this inspection is collected and the cause of failure is analyzed.

Next, again turn the main switch knob 7 to "OF".
Slide operation to the “F” side and press the strobe charging switch 11 to charge the strobe unit 15. afterwards,
When the shutter button 6 is pressed, the pressing pin 6b formed on the lower portion of the shutter button 6 presses the intermediate lever 115 downward as shown in FIG. The intermediate lever 115 is
The pin 114 formed on the front cover 19 is rotated clockwise to push down the claw portion 118c engaged with the engaging portion 117. The locking release lever 118 with the claw portion 118c pushed down is pushed down counterclockwise about the connecting portion 118a with the front cover 19 as a fulcrum, and the pushing portion 118b pushes the vertical piece 74a of the locking lever 74 to slightly pull it back. Rotate clockwise.

When the locking lever 74 is rotated counterclockwise, the engagement between the protrusion 74c of the locking lever 74 and the rising piece 90c of the shutter driving lever 90 shown in FIG. The lever 90 is rotated counterclockwise by the bias of the spring 92. At this time, the kicking arm 90
d kicks the shutter blade 96, and the shutter blade 96 rotates against the bias of the spring 98 to open the exposure opening 86. As a result, the subject light that has passed through the taking lens 10 reaches the film 21b and is exposed.

At the same time, the shutter blade 96 turns on the well-known light emitting switch 15e of the strobe unit 15, so that strobe light is emitted from the strobe light emitting section 5 through the strobe opening 110 of the front cover 19.

Further, as the locking lever 74 is rotated counterclockwise in FIG. 4, the pin 75 releases the counterclockwise pressing of the switching lever 69. However, the main switch knob 7 is "OFF"
Since it is set to the side, the switching lever 69 is continuously pressed in the counterclockwise direction, and the first contact piece 79 and the second contact piece 81 are not contacted with each other, so that the motor 31 is not rotated and the film winding is not performed. .

At the time of this shutter release, the function inspection of the strobe unit 15 and the function inspection of the shutter speed of the shutter mechanism are performed. The unit body 3 that fails this inspection is collected and the cause of failure is analyzed, and the unit body 3 that passed the test is transported to the next step. In addition, since the film 21b is not used for one frame in the inspection at the time of manufacturing, it is possible to take a predetermined number of images or more on the loaded film 21b. It should be noted that in a lens-fitted film unit in which the strobe unit 15 is not incorporated, only the shutter speed is inspected.

The unit main body 3 conveyed to the next step is mounted with the outer case 4 to form the lens-fitted film unit 2 shown in FIG. 2, which is stored in a well-known packaging bag and shipped. Film unit with lens 2 stored in a packaging bag
Are packaged in a cardboard box or the like and transported to each store. Even if the shutter button 6 is pushed from above the packaging bag by the vibration or shock during the transportation, it also serves as an inspection at the time of manufacturing. Main switch knob 7 is set to the "OFF" position,
Since the state immediately after the shutter release is completed, the shutter release is not newly performed and the film is not wound up, and the loaded film is prevented from being wasted.

A user who purchases the lens-fitted photo film unit 2 breaks the packaging bag and takes out the lens-fitted photo film unit 2 stored therein. Even if the shutter button 6 is pressed by mistake at this time, A new shutter release is not performed to wind up the film, and the loaded film is not wasted.

Then, the user slides the main switch knob 7 to the "ON" side in accordance with the explanation written on the outer cover 4. Then, since the switching lever 69 releases the pressing force from the operation plate 57, the elasticity of the first contact piece 79 separates it from the third contact piece 83 and returns to the original position. Further, as shown in FIG. 6, the second contact piece 81 at this time is
Is deformed to the first contact piece 79 side by the pressing of the pressing piece 116a formed on the pressing lever 116, so that the contact portion 79a of the first contact piece 79 and the second contact piece 81 are brought into contact with each other. Then, the circuit portion 84 is closed, the motor 31 is rotated, the film 21b is wound up by one frame, and the shutter charge is performed in conjunction with this to complete the preparation for photographing.

Then, after the subject is confirmed by looking through the viewfinder eyepiece window 9b (see FIG. 3) and the composition is determined, the shutter button 6 is pressed. After that, the shooting is continued in the same manner, and when the shooting of all the frames of the film 21b is completed, the entire film 21b is wound up in the cartridge 21a, and the motor 31 is continuously rotated. The user
After confirming this, turn off the main switch knob 7
Slide to the side to turn off the power, and hand over the film-equipped film unit 2 to a photo shop for simultaneous printing.

In the above embodiment, the "OF" of the main switch in the assembly process of the lens-fitted photo film unit.
The "F" operation was performed immediately before the battery was loaded, but this is because the main switch is switched from "OFF" to "ON" by mounting the rear cover.
This is for the purpose of preventing the film from being rolled up due to the shift of the position. When the main switch is arranged at a position where it is not easily affected by the mounting of the rear cover, the order of the steps may be exchanged.
