Abstract

PURPOSE: To prevent strobe light from entering film by providing a light shielding member, that is, a printing surface such as a transfer layer or a light shielding ring on the side surface of a transparent cover member on a photographing lens side. CONSTITUTION: A camera main body is covered with a front cover 1, a transparent cover member 2 and a back cover 3, and the cover member 2 is made of transparent resin material. The transfer layer 15 is printed on the surface side of the cover member 2 so as to include the side surface E on the photographing lens side surrounding the optical path A of the photographing lens. Since the transfer layer 15 is printed even on the side surface E of the cover member 2 on the photographing lens side, the strobe light is prevented by the side surface E and does not advance to the film 7 even though the strobe light enters the cover member 2. Printing is not performed on the back surface side of the cover member 2, but the light is shielded by other parts, so that the unnecessary light is prevented from being made incident through the photographing lens 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera with a built-in strobe.

[0002]

2. Description of the Related Art Recently, in cameras with a built-in flash,
The flash unit panel and the periphery of the photographing lens unit are formed of a transparent material, such as a transparent resin material, as an integral transparent cover member, and the transparent cover member covers a part of the front surface of the camera body. The transparent cover member is black. A white or other printing or transfer layer was printed, and aluminum was vapor-deposited to form a strobe window. This method can shorten the camera manufacturing process, for example, by forming a window in an opaque member and engaging a transparent member in the window to form the window, and at the same time, make the strobe window have an arbitrary shape. Further, there is an advantage that characters, symbols, patterns, colors, etc. can be formed on the cover at the same time.

[0003]

By the way, the flash unit panel and the peripheral portion of the photographing lens portion are integrally formed by the transparent cover member as described above, and the transparent cover member extends to the vicinity of or around the photographing lens. In a camera with a strobe, when strobe light is emitted to a transparent cover member provided in front of the strobe light emission part, a part of the strobe light goes straight through the transparent cover member or is diffusely reflected and transmitted therethrough. I discovered that I got out of the side of the taking lens side, went through the taking lens part, and penetrated the film screen at the time of flash photography to make a photograph with unnecessary light.

A method of printing a transfer layer on a transparent cover member of a conventional camera with a strobe will be described with reference to FIG.

FIG. 6 is a diagram for explaining a method for printing a transfer layer on the side surface of the transparent cover member of the conventional strobe camera on the side of the taking lens.

As shown in FIG. 6, a resin is injected from the gate 100 between the fixed mold 20 and the movable mold 21 which are combined and molded to form the transparent cover member 2. At the same time, the transfer layer 15 on the transfer sheet 15 'which is fixed to the mold in advance is printed (transferred) on the formed transparent cover member in the state shown in FIG. This transfer technique is described in Japanese Patent Application Laid-Open No. 4-158014, so its details will be omitted. The parting line PL of the fixed mold 20 and the movable mold 21 when printing the transfer layer is generally at the position shown in FIG. 6 due to the problem of the elongation of the transfer layer 15 and the position of the transfer sheet 15 ′. Target. The side surface E of the transparent cover member 2 on the side of the taking lens is perpendicular to PL, and the transfer layer 15 does not exist.

When the transparent cover member manufactured by the above method is used, unnecessary light is generated from the side surface of the transparent cover member facing the taking lens when the strobe light is emitted, so that the taking lens is transparent in the optical axis direction. If the projection lens is projected sufficiently far forward from the cover member, unnecessary light will not enter the shooting lens due to the lens barrel or the like, but as shown in FIG. 2, the shooting lens retracts from the transparent cover member in the optical axis direction. If it is, or if it is at almost the same position, the problem as described above occurs due to the unwanted light entering the film screen.

The present invention has been made in view of the above points, and in a camera with a strobe in which a panel of a strobe section and a peripheral portion of a photographing lens section are integrally formed by a transparent cover member, strobe light is prevented from entering a film. The purpose is to provide means for preventing.

[0009]

In order to solve the above problems, according to the present invention, a stroboscopic light emitting section, a photographing lens, and a transparent cover integrally formed between the front of the stroboscopic light emitting section and the vicinity of the photographing lens. And a light-shielding member is formed on the side of the transparent cover on the side of the taking lens, for blocking the strobe light from the strobe light emitting part that is transmitted through the transparent cover and enters the taking lens. Characterize. The light blocking member is formed by printing a light non-transmissive film on the transparent cover. Further, the light non-transmissive film is a transfer layer. Further, the transparent cover end portion is formed so as to surround the photographing lens, and the light shielding member is a light shielding ring that engages with the transparent cover end portion.

[0010]

The light shielding member, that is, the printing of the transfer layer or the light shielding ring prevents the stroboscopic light from entering the film.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a strobe camera according to the present invention. 2 is a sectional view taken along the line II-II of FIG. FIG. 3 is a diagram illustrating a method of printing a transfer layer on the side surface of the transparent cover member of the camera with strobe of the present invention on the side of the taking lens.

The camera body is covered with a front cover 1, a transparent cover member 2 and a back cover 3, which are separately molded in a thin plate shape with synthetic resin. In particular, the transparent cover member 2 is made of a transparent resin material. , Strobe window 10, viewfinder window 1
The transfer layer is printed except for 1 and the like. The transparent cover member 2 is engaged with the front cover 1.

An unexposed film accommodating chamber 4 and an exposed film accommodating chamber 5 are formed in the main body with an image frame interposed therebetween, a cartridge 6 is accommodated in the unexposed film accommodating chamber 4, and the exposed photographic film 7 is The exposure film storage chamber 5 is wound up (see FIG. 2).

A photographic lens unit 8 including a photographic lens is fixed to the center of the main body, and the front surface of the photographic lens unit 8 is covered with a lens barrier 9. A peripheral portion surrounding the optical path A of the photographing lens unit 8, for example, a frame for holding the lens barrier 9 is made of a transparent panel integrally with the transparent cover member 2.
A viewfinder is provided in the upper center of the main body, and a strobe light emitting section including a flash tube of a strobe is provided above the unexposed film storage chamber 4 of the main body. The front surface of the strobe light emitting portion is covered with a strobe window 10 of a transparent cover member 2, and the finder is a finder window 1 of the transparent cover member 2.
Covered with 1. As described above, the flash unit panel of the camera with a flash unit of the present invention and the peripheral panel of the photographing lens unit are integrally configured by the transparent cover member 2 (see FIG. 1).

Conventionally, when strobe light is emitted from a flash tube of a strobe, a part of the strobe light goes straight through the transparent cover member 2 or is diffusely reflected and transmitted, and is emitted from the side surface of the transparent cover member 2 on the side of the taking lens. After passing through the shooting lens unit 8,
Enters as unnecessary light on the film screen during flash photography. In order to prevent this, the following measures are taken in the camera of this embodiment.

As shown in FIGS. 2 and 3, the transparent cover member 2
A transfer layer is printed on the front surface side (the side that becomes the external appearance of the camera) including the side surface E of the photographing lens side that surrounds the photographing lens optical path A. No print is formed on the back surface side of the transparent cover member, but it is shielded by other components so that unnecessary light does not enter through the taking lens. Here, a method of printing the transfer layer on the side surface E of the transparent cover member 2 on the side of the taking lens will be described with reference to FIG.

As shown in FIG. 3, the resin is injected from the gate 100 between the fixed mold 20 and the movable mold 21 to be combined and molded to form the transparent cover member 2. The parting line PL is formed at the position shown in the drawing, and the side surface E of the transparent cover member facing the taking lens is not perpendicular to PL but is inclined at an angle θ with respect to a line perpendicular to PL. Transfer sheet 1 fixed to a mold in advance at the same time as the above resin molding
The side surface E is printed on the transparent cover member on which the transfer layer 15 on 5'is formed. By making an angle θ with respect to a line perpendicular to the side surfaces E and PL, PL can be set at the position shown in the figure, and printing up to the side surface E is possible. (See FIG. 6 for comparison). Angle θ
Becomes close to a small angle, that is, a line perpendicular to PL,
A good print cannot be obtained because cracks are generated in the side surface E due to elongation (drawing) caused by stress applied to the transfer sheet 15 ′ and the transfer layer 15 on the transfer sheet during molding. In this embodiment, a good print is obtained on the side surface E by setting the angle θ to about 20 degrees.

As described above, since the transfer layer is printed even on the side surface E of the transparent cover member 2 on the side of the photographing lens, even if the stroboscopic light enters the transparent cover member, the light is blocked by the side surface E, so that the film should enter the film. There is no.

In the present embodiment, the transfer layer was printed on the transparent cover member by the transfer method to form the light shielding member, but the present invention is not limited to this, and may be normal printing such as tampo printing or manual work. The light shielding member may be formed by printing with.

As another embodiment, as shown in FIG. 4, a light-shielding ring 16 made of a light non-transmissive material such as black ABS or PC resin or metal such as aluminum to prevent reflection is shown in FIG. As shown in the figure, the transparent cover member 2 is attached to the side surface E of the transparent cover member 2 on the photographing lens side by fitting or adhering.

Also in this case, it is possible to prevent the strobe light from passing through the transparent cover member 2 and entering the film from the side E of the photographing lens side through the photographing lens. Although PMMA is used for the transparent cover member in this embodiment, a PC or the like may be used in consideration of transparency and moldability.
