However, since such a motor has conventionally been mounted directly on the main body of the instant camera, the vibration of the motor is transmitted to the entire instant camera, and the rotation noise during the operation of the motor is increased. There was a problem. Such noise generated by the motor makes it difficult to take a picture with an instant camera, particularly in a place where quietness is required.

For this reason, it is conceivable to use an ultrasonic motor or the like having a quieter operation sound as a built-in motor. However, since such a motor is generally large in size and expensive, an instant camera is required. However, there are many problems such as an increase in size and an increase in manufacturing cost.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an instant camera in which the operating noise of a built-in motor is reduced and quietness is improved without increasing the manufacturing cost. Aim.

[0006]

In order to achieve the above object, in an instant camera according to the present invention, a pair of rollers for feeding an instant film out of a main body is driven below a dark box constituting an exposure light path of the instant camera. A pair of ribs that pinch the motor to be rotated in the direction of the rotation axis are projected, and a gap is provided between the lower surface of the dark box and the motor,
An elastic body is provided in this gap. According to a second aspect of the present invention, the elastic body is made of a silicon-based adhesive.

The rear cover 9 is provided with a film chamber cover 48 for inserting and removing the film pack 42 into and from the film pack storage chamber 16 so as to be openable and closable.

The main body 7 is provided with a known photographing mechanism (not shown) and a lens barrel 3 for holding a photographing lens 11.
A finder 6 is provided at the upper right. A discharge unit 4 for discharging the photographed instant film 41 to the outside is provided on an upper portion of the main body unit 5. The discharge unit 4 is provided with a developing roller pair 17 composed of two rollers 17a and 17b, and a pressing spring 18 for pressing the two rollers 17a and 17b together.

The lower part of the main body 9 is provided with the developing roller pair 1.
A motor 10 for rotating the motor 7 is provided. Then, the developing roller pair 17 is rotated via the gear unit 5 provided on the left side surface of the main body 7. The gear unit 5 includes an instant film 4 already photographed.
A claw plate 18 for pushing up the instant film 41 is provided to a position where the leading end of the developing roller 1 is sandwiched between the pair of developing rollers 17, and is driven by the motor 10 in the same manner as the pair of developing rollers 17.

As shown in FIG. 1, the motor 10 for driving the developing roller pair 17 and the claw plate 18 includes a pair of ribs 21 projecting from the lower surface of a dark box 31 constituting the main body 9. , 22 are provided with notches 21 a, 21 b, and projecting portions 1 protruding forward and backward near the center of the motor 10.
The motor 10 is mounted in the direction of the rotation shaft 10a by inserting the motors 0b and 10c, respectively.

As shown in FIG. 1 and FIG.
A gap is formed between the outer periphery 10d of the main body 7 and the outer surface of the dark box 31 constituting the aperture of the main body 7, and the elastic body 20 is provided in the gap. Thus, the motor 10 and the dark box 3
An elastic body 20 is provided between the main body 1 and the motor 10 so that the motor 10 does not come into direct contact with the dark box 31. Do not transmit to the whole part 7.

The operation of the instant camera having such a configuration will be described. When using the instant camera 2 of the present invention, first, the film chamber cover 48 is opened and the photographic film pack 42 is stored in the film pack storage chamber 16.
To store. The film chamber cover 48 is closed again. Then, the instant camera 2 is held by gripping the grip portion 13, and the photographing range of the subject to be photographed is confirmed with the finder 6. When the photographing range is determined, when the release button 14 is pressed gently, a photographing mechanism (not shown) operates, and the instant film 41 on the front of the film pack 42 is operated.
The image of the subject is exposed, and shooting of one image is completed.

When the photographing of the first instant film 41 is completed, the motor 10 operates to move the claw plate 18 upward. Then, the photographed instant film 41 is pushed up and raised until the leading end reaches the developing roller pair 17. When the tip of the instant film 41 reaches the developing roller pair 17, the rotation of the motor 10 rotates the developing roller pair 17, and the instant film 41 is fed out of the instant camera 2 while being sandwiched between the rollers 17a and 17b. .

When the instant film 41 is fed, a developing pod (not shown) provided on the upper portion of the instant film 41 is sandwiched between the developing roller pair 17 and crushed, and the developing solution is discharged.
Is uniformly spread on the exposed surface of the. Then, a clear subject image emerges on the exposure surface of the instant film 41.

When the instant film 41 is fed out, the motor 10 operates and continues to rotate. However, the elastic body 20 for absorbing vibration is provided between the motor 10 and the dark box 31. In addition, the vibration of the motor 10 as a noise source is hardly transmitted to the main body 7. For this reason, the operation sound of the motor 10 is extremely quietly suppressed, and no loud operation sound is generated. Therefore, it is possible to perform photographing without any problem even in a place where quietness is required.

Then, such an instant camera 2
Is that only an elastic body such as a silicone adhesive is attached between the motor 10 and the dark box 31 and no expensive material such as an ultrasonic motor is used, so that the manufacturing cost of the instant camera increases. The size and weight do not increase.
