Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a data imprinting device for a camera that imprints data such as date on a film.

[0002]

2. Description of the Related Art FIG. 4 is a plan view of a conventional camera data imprinting device. FIG. 5 is a cross-sectional view taken along the line 4c and FIG. 6 is a cross-sectional view taken along the line 4d, showing the arrangement structure of the liquid crystal display device for external display and the liquid crystal display device for imprinting, respectively. As shown in FIGS. 4 to 6, the camera data imprinting device includes an external display liquid crystal display device 1, an imprinting liquid crystal display device 2, a circuit board 3, a fixed frame A4, a fixed frame B5, a driving IC 6, It is composed of a light source 7 for imprinting, a connector 8 for connecting a liquid crystal display device, and a reflecting mirror 9. An optical path 10 through which light from the imprinting light source 7 passes is formed on the fixed frame A side. To explain the mechanism in which the data of the camera data imprinting device is imprinted, the light emitted from the imprinting light source 7 passes through the optical path 10 and is bent by the reflecting mirror 9 toward the imprinting liquid crystal display device for imprinting. It reaches the film through the liquid crystal display. At this time, the lighting unit of the imprinting liquid crystal display device 2 has a mechanism through which light is transmitted, and the shape of the displayed data is imprinted on the film. Since the liquid crystal display device for external display faces the outside of the camera and the liquid crystal display device for imprinting faces the film side, the liquid crystal display device for external display and the liquid crystal display device for imprinting are opposite to each other with the circuit board 3 as the center. It is located in the position.

[0003]

However, in the prior art, since the external display liquid crystal display device 1 and the imprinting liquid crystal display device 2 are arranged on both sides of the circuit board 3, the substrate on the circuit board 3 is arranged. It was necessary to provide terminals for connection with the liquid crystal display device on both sides of the. Therefore, the circuit board 3 must have a double-sided wiring structure, which causes a reduction in the cost of the board. Also, since the liquid crystal display device is on both sides, the imprinting and external display liquid crystal display device are assembled in the fixed frame A4 and the fixed frame B5 respectively when the camera data imprinting device is assembled, and then the liquid crystal display device for imprinting is displayed. Since the fixed frame B5 in which the device is incorporated is inverted and combined with the circuit board 3 and the fixed frame A4 in which the liquid crystal display device for external display 1 is incorporated, the assembly takes a long time. In addition, since the imprinting liquid crystal display device 2 must not fall when the fixed frame B5 is inverted, the structure of the fixed frame B5 is complicated and the accuracy of the fixed frame B5 cannot be improved. There is also a problem that the imprinting liquid crystal display device falls when B is inverted.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a data imprinting device for a camera, a liquid crystal display device for external display, and a liquid crystal display device for imprinting a circuit board of the data imprinting device for camera. It is arranged on the film side, and the wiring of the circuit board is one side wiring.

EXAMPLES The present invention will be described in detail below based on examples. FIG. 1 is a plan view of a data imprinting device for a camera of the present invention. FIG. 2 is a sectional view taken along the line 1a in FIG. 1 and FIG. 3 is a sectional view taken along the line 1b in FIG. 1, showing the arrangement structures of the liquid crystal display device for external display and the liquid crystal display device for imprinting, respectively. 1 is a liquid crystal display device for external display, 2 is a liquid crystal display device for imprinting, 3 is a circuit board, 4 is a fixed frame A, 5 is a fixed frame B, 6 is a liquid crystal display device and a projection light source driving function and a clock function. It is the IC that I have. Reference numeral 7 is a light source for imprinting, 8 is a connector for connecting a liquid crystal display device, and 9 is a reflecting mirror. In FIG. 1, the external display liquid crystal display device 1 is arranged below the fixed frame A4 and the circuit board 3. The fixed frame A4 and the circuit board 3 overlap with the external display liquid crystal display device 1 with holes, so that the external display liquid crystal display device 1 can be viewed from the front side.
The display of can be confirmed.

FIG. 2 is a sectional view showing an assembled state of the liquid crystal display device 1 for external display. The external display liquid crystal display device 1 is incorporated in the fixed frame B5, and the circuit board 3 is mounted on the fixed frame B5. The external display liquid crystal display device 1 and the circuit board 3 are connected by a liquid crystal display device connection connector 8. FIG. 3 is a view showing a state in which the imprinting liquid crystal display device 2 is incorporated, and the imprinting liquid crystal display device 2 is the same as the external display liquid crystal display device 1 in the fixed frame B.
Built in 5. Since the optical path 10 through which the light from the imprinting light source 7 passes is set on the fixed frame B side, the imprinting light source 7 is also arranged on the fixed frame B side, and on the liquid crystal display device connection side of the circuit board 3. Can be implemented. Since the optical path frame B also has a space for the IC 6,
6 can also be mounted on the liquid crystal display device connection side of the circuit board 3. The wiring on the circuit board is only required on the liquid crystal display device side, and a single-sided wiring board can be realized. Reflector 9
Is attached to the fixed frame A4, and when the fixed frame A is incorporated in the fixed frame B, the reflecting mirror 9 is dropped under the circuit board 3. Data can be imprinted in the same manner as in the past by changing the arrangement of other parts according to the position of the liquid crystal display device.

In the assembling method with such a structure, first, the liquid crystal display device 1 for external display and the liquid crystal display device 2 for imprinting are assembled in the fixed frame B5, and the connector 8 for connecting the liquid crystal display device is put on the circuit. The board 3 is assembled and finally fixed by the fixing frame A4 to complete the assembly. Since the assembly is completed simply by placing the parts on the fixed frame B5 in order, the work for reversing the fixed frame B5, which has been performed in the conventional assembly of the data imprinting device for the camera, is eliminated, which reduces the assembly time. The liquid crystal display device fixing structure for imprinting the fixing frame B5 is also unnecessary. Further, the fixed frame B reversing device of the assembling equipment in the data imprinting device for the camera becomes unnecessary.

[0008]

As described above, in the camera data imprinting device of the present invention, the external display liquid crystal display device and the imprinting liquid crystal display device are arranged on the film side of the circuit board of the camera data imprinting device. By doing so, there is a great effect in reducing the component cost and the assembly cost, such as single-sided wiring of the circuit board, reduction of the assembly time, simplification of the assembly equipment.
