Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a simplified camera with a built-in flash.

[Conventional technology]

A film unit with a lens (trade name "Sharun Run Hi", etc.) by the applicant, or a film unit with a lens with a built-in flash (so that you can easily enjoy photography even if you do not have an ordinary camera) The product name “Sharp Run Flash” is available on the market. Such a film unit with a lens is a unit with a simple shooting mechanism that contains a film with a cartridge in advance, so that it can be disposable. Therefore, the built-in flash also has the lowest cost.

[Problems to be solved by the device]

The conventional lens-equipped film unit with a built-in strobe uses, for example, an AA alkaline battery as a strobe battery. Then, as shown in FIG. 4, the contact pieces 4 and 5 are arranged in the battery chamber 6 so as to contact the − terminal 2 and the + terminal 3 arranged on both end surfaces of the cylindrical battery 1. ing. The battery chamber 6 is provided in an empty space below the dark box-shaped exposure chamber 60 for exposing the film in order to make the lens-fitted film unit compact, and the battery 1 is housed with the longitudinal direction of the battery 1 oriented horizontally. Has become. On the other hand, the strobe 7 is a film storage chamber 61 which is provided on the side of the exposure chamber 60 and stores an unexposed film.
It is located next to. For this reason, the substrate 8 of the strobe 7 is positioned close to one of the terminals of the battery 1 arranged in the center of the lens-fitted film unit.

Therefore, it is necessary to form at least one of the contact pieces 4 and 5 so as to correspond to the length of the battery 1. For this reason, since the contact piece becomes long, an engaging portion or the like for holding the contact piece must be formed in the battery chamber, and the shape of the battery chamber becomes complicated. Further, there is a problem in that the contact piece becomes complicated to be assembled in the battery chamber and the contact piece itself becomes long, which increases the manufacturing cost.

Such a problem exists not only in the lens-fitted film unit, but also in the case of a simple camera with a built-in flash that is produced at low cost.

The present invention is intended to solve the above problems, and an object thereof is to provide a simplified camera with a built-in strobe at a low cost by simplifying the structure of the contact piece of the strobe battery.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention arranges one terminal of a rod-shaped power supply battery on an end surface on the side close to a substrate, and the other terminal on the peripheral surface of the rod-shaped power supply battery close to the terminal. The strobe board is provided with a first contact piece which is disposed and contacts the terminal on the end surface side, and a second contact piece which contacts the terminal on the peripheral surface side adjacent to the first contact piece.

[Action]

The battery is connected to the strobe by the first contact piece that contacts the terminal on the end surface side of the battery and the second contact piece that contacts the terminal on the peripheral surface side of the battery. Since the contact pieces are arranged close to each other, it is not necessary to form one contact piece long as in the conventional case, and the contact piece is shortened. Therefore, the structure and attachment of the contact piece are simplified, and the cost can be reduced.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 shows the appearance of a unit main body 10 of a lens-fitted film unit embodying the present invention and a paper box 11 accommodating the same. A simple photographing mechanism and a strobe are incorporated in the unit body 10, and a 135 film with a cartridge is preloaded so that the user cannot take it out. The unit body 10 is used while being put in the paper box 11. Therefore, in order to expose the photographing lens 12, the finder objective aperture 13, the shutter button 14, the film counter window 15, the film winding knob 16, the stroboscopic light emitting part 17, etc., which are provided in the unit body 10, to the paper box 11. The opening is formed.

FIG. 3 shows a state where the bottom plate of the unit main body 10 is removed. The unit main body 10 is provided with a film roll chamber 20 for accommodating the film in a roll shape and a cartridge chamber 21 for accommodating the cartridge. An exposure chamber 22 for exposing the film is formed between these chambers 20 and 21. A strobe 24 is arranged next to the film roll chamber 20. The strobe 24 is configured by attaching various parts to a board 25.

Below the exposure chamber 22, a battery chamber 27 that accommodates a strobe battery 26 is formed. In the battery chamber 27, a part of the substrate 25 is arranged so as to project. Substrate of battery compartment 27
25 includes a + contact piece 30 that contacts the + terminal 28 of the battery 26,
The terminal 29 and the contact piece 31 are attached by soldering. As the battery 26, an AA alkaline battery is used.

As shown in FIG. 1, the battery 26 does not have a metal or plastic outer casing on which a trademark, an effect, or the like is printed in order to reduce the cost. The + terminal 28 also serves as an exterior body and is formed in a bottomed tubular shape. The − terminal 29 is attached to an insulating gasket 33 arranged so as to close the opening of the + terminal 28 having a cylindrical shape with a bottom. Gasket 33 is +
It is attached by closing the peripheral edge of the terminal 28,
Further, this gasket 33 is locked by a peripheral groove 35 so as not to fall inside. A sealing member 36 is fixed to the outer side portion of the gasket 33 so as to straddle the tip portion of the + terminal 28 and the peripheral portion of the − terminal 29.

The negative contact piece 31 is composed of a rectangular contact piece main body 40 and a connecting piece 41 extending from the main body 40. Contact piece body 40
Two slits 42 are formed along the diagonal line, and of the triangular pieces 43 to 46 divided by the slit 42, two triangular pieces 43, 44 located in the lateral direction are obliquely raised.
Then, due to the springiness of the triangular pieces 43, 44, the battery 26-
The triangular pieces 43 and 44 elastically contact the terminal 29. The tip of the connecting piece 41 is inserted into the mounting hole of the substrate 25 and then soldered, so that the contact piece body 40 is fixed in close contact with the side wall 48 of the battery chamber 27.

The + contact piece 30 is a contact piece body composed of a pair of sandwiching parts 50.
It is composed of 51 and a connecting piece 52 extended to this. The pair of sandwiching portions 50 are formed in an arc shape having an inner diameter slightly larger than the outer diameter of the circumferential groove 35. A locking claw 53 is provided at the tip of the sandwiching portion 50 to prevent it from falling off, and a contacting claw 54 is formed between the two sandwiching portions 50 so as to project therefrom. The diameter of an imaginary circle including the tips of the claws 53, 54 is smaller than the outer diameter of the circumferential groove 35. Therefore, when the battery 26 is set in the + contact piece 30, the tips of the claws 53 and 54 strongly contact the circumferential groove 35 of the battery 26 due to the elastic restoring force of the sandwiching portion 50. The tip of the connection piece 52 is inserted into the attachment hole of the substrate 25 and then soldered, so that the contact piece body 51 is erected on the bottom wall 55 in the battery chamber 27.

Next, the operation of this embodiment will be described. When the unit body 10 is assembled, the battery 26 is inserted into the battery chamber 27. At this time,
Since the circumferential groove 35 of the battery 26 is held by the holding portion 50 of the + contact piece 30, the battery 26 is housed in the battery chamber 27 without dropping. By this accommodation, the-terminal 29 of the battery 26 faces and contacts the triangular pieces 43, 44 of the-contact piece 31. By thus setting the battery 26 in the battery chamber 27 and assembling the other components, the assembly of the lens-fitted film unit is completed.

Photographing using the lens-fitted film unit is performed by pressing the shutter 14 as in a normal camera. After shooting one frame, the film winding knob 16 is rotated to wind the film. As is well known, when the film is wound up, the sprocket that rotates by engaging with the film perforation rotates by one frame, and then the rotation is restricted, and the one frame feed is completed. The shutter charge is performed during this one-frame advance, and the preparation for the next shooting is also completed. When the shooting of all frames is completed, for example, the filmed film is caught in the built-in patrone. The film thus photographed is submitted to the developing shop as the film unit. At the developing station, the unit main body is disassembled or destroyed, and the cartridge containing the exposed film is taken out and developed. Further, the battery 26 is taken out at the same time as the cartridge is taken out, and is discarded separately from other unit body component parts.

In addition, in the said Example, although the battery exterior body was made into the + terminal, it is not restricted to this aspect. Further, although the battery has been described as having the circumferential groove provided on the circumferential surface, the present invention can be applied to a battery having no circumferential groove. In this case, the peripheral surface of the battery is sandwiched between the sandwiching parts. In addition,
The second contact piece does not necessarily have to sandwich the battery, but the contact of the second contact piece to the peripheral surface may be changed to change the shape of the battery storage portion and hold the battery securely in the battery storage portion itself. Of course.

Further, in the above-described embodiment, the present invention is applied to the lens-fitted film unit, but the present invention is not limited to this and can be applied to a low-cost camera.

[Effect of device]

As described above, according to the present invention, the battery terminal is
One is an end face, the other is a battery arranged on the peripheral surface close to this end face, and a first contact piece that contacts the end face side terminal,
Since the substrate is provided with the second contact piece that comes into contact with the peripheral surface side terminal of the battery at a position close to the first contact piece, each contact piece can be arranged close to each other, and each contact piece is configured to be short. be able to. Therefore, since the attachment to the substrate is simplified and the contact piece is shortened, the cost can be further reduced.
