[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loupe having an illuminating means. More specifically, when a lens portion is protruded from a main body case by a sliding means, the illuminating means swings to the object side in conjunction with this. It was made.

[0002]

2. Description of the Related Art Loupes used for viewing newspapers and books are required to be small, compact and easy to use.

For this reason, conventionally, for example, Japanese Utility Model Publication No. 63-672
No. 6 has been proposed. In this device, a main housing provided with a lens and a light bulb for illumination and a sub-housing containing a power supply battery are openably and closably connected by a hinge portion. When not used, the main housing and the sub-housing are connected. When the main housing is rotated and opened to use it as a loupe, the switch is turned on in conjunction with this rotation, the light bulb lights up and the paper surface etc. is illuminated brightly It is supposed to.

[0004]

However, the above-mentioned conventional device has two housings, a main housing and a sub-housing, and the housing is horizontally rotated to take out and store the lens unit. Therefore, it was difficult to perform the operation easily with one touch.

[0005] In addition, since the light from the bulb is irradiated in parallel with the main surface of the lens, the amount of light passing through the lens and illuminating the object is small, and the object cannot be illuminated brightly. was there. Therefore, an object of the present invention is to provide a loupe that is small, compact, easy to use, and can brightly illuminate an object.

[0006]

For this purpose, the present invention provides a main body case 1 and a lens portion 3 slidably disposed inside the main body case 1 and protruding and retracting from the main body case 1.
And an illuminating means 11 disposed inside the main body case 1 so as to be swingable about a hinge 15, and interlocked with the projection of the lens unit 3 from the main body case 1,
Above causes the swing of the illumination means 11 to the object side
In conjunction with storing the lens unit 3 in the main body case 1,
The lens, which causes the lighting means 11 to swing back to its original position,
The pressing portion 27 that moves integrally with the pressing portion 3 and the pressing portion 27
A neck comprising a pressed part 16 to be pressed and a posture returning means 18
It has a swing mechanism.

[0007]

In the above construction, the lens section 3 is connected to the main body case 1
It can be easily put in and out and swing the lighting means 11
To reduce the length and thickness of the loupe body,
Can be In use, the lighting means 11
The head can be swung to illuminate the object brightly,
Can be improved. Furthermore, the direct lighting means 11
The user can turn around without touching
No feeling of discomfort.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded view of a loupe, and FIG. 2 is a sectional view of a main part. Reference numeral 1 denotes a thin box-shaped main body case, which is composed of an upper case 1a and a lower case 1b, and has a slit-shaped opening 2 formed at a tip end thereof.

Reference numeral 3 denotes a lens portion, which is mainly composed of a plate-like lens 4 made of a Fresnel lens. The planar shape of the distal end surface of the lens portion 3 is an arc of an outer convex, and support means 6 is attached to both sides at the rear.

Reference numeral 11 denotes illumination means horizontally disposed on both sides of the lower case 1b. The lighting means 11 includes a socket 12 and the light emitting element 1 mounted on the socket 12.
Consists of three. As the light emitting element 13, a nipple ball having good directivity, an LED with low power consumption, or the like is used. 19 is a power battery stored in the rear part of the main body case 1,
Reference numeral 20 denotes a conductive plate, 5 denotes a battery lid detachably mounted on the upper case 1a, and 28 denotes a photosensitive element such as CdS provided on the upper case 1a.

The socket portion 12 is supported by a hinge portion 15 supported by a bearing 14 so that the socket portion 12 can swing vertically. A rib-shaped pressed portion 16 is provided upright on the upper surface of the socket portion 12. Below the socket portion 12, a lever-type switch means 18 is provided. The switch means 18 is made of a spring material, and resiliently springs the socket portion 12 clockwise by the spring force. When the spring force of the switch means 18 is small, a spring material is separately provided between the socket 12 and the lower case 1b,
With this spring material, the socket part 12 may be resiliently clockwise.

In FIG. 1, an operation element 21 is provided on a side surface of the support means 6 so as to protrude therefrom. The operator 21 is exposed from a slit 22 formed by cutting out a side surface of the lower case 1b in an assembled state. A rib 23 is provided on the side surface of the support means 6, and this rib 23 is provided on the lower case 1b.
Elastically fit into holes 24 and 25 formed on the inner surface of the. The ribs 23 and the holes 24 and 25 serve as moderating means for positioning the lens unit 3 at the protruding position and the storage position.

In FIG. 2, a rib-shaped pressing portion 27 is projected from a rear portion of the lens portion 3. When the main body case 1 is held by hand and the operator 21 is slid with a fingertip, the lens unit 3 slides along the guide shaft 7 and protrudes and retracts from the opening 2 on the distal end surface of the main body case 1. Note that a configuration may be employed in which a pressing spring material is provided behind the lens unit 3 and the lens unit 3 slides and protrudes with one touch.

When the lens portion 3 is projected, the pressing portion 27 presses against the pressed portion 16, and the illumination means 11 is made of a spring material.
The light emitting element 13 is slightly swung downward against the spring force of the switch means 18 as the posture returning means, and slightly protrudes from the window 26 opened in the lower case 1b (see the chain line in FIG. 2). In this state, the switch means 18 is turned on, and the light emitting element 13 is turned on. In this state, the rib 23 is fitted into the hole 24 to position the lens 3 at the projecting position.
Alternatively, the illumination unit 11 may be swingable and the switch unit 18 may be turned on, and the illumination unit 11 may be manually finely adjusted in the vertical direction. This is to cope with a difference in the distance between the object and the lens unit 3 due to a difference in individual visual acuity.

When the operator 21 is slid backward, the lens unit 3 is housed in the main body case 1, and at the same time,
The pressing state of the lighting means 11 is released, the lighting means 11 returns to the original posture by the spring force of the spring member 17, the switch means 18 is opened, and the light emitting element 13 is turned off. In this state, the rib 23 is fitted into the hole 25 and the lens 3
To the storage position.

As described above, the loupe allows the lens section 3 to be moved into and out of the main body case 1 by one-touch operation. Also, the lighting means 11 is linked with the movement of the lens unit 3 into and out.
The light-emitting element 13 is directed downward to the object side in a state where the lens unit 3 is protruded from the main body case 1 and the switch means 18 is turned on to light up. Can be brightly illuminated. In addition, by providing the photosensitive element 28,
Even in the daytime when the lens 3 is protruded and the switch means 18 is turned on, the electric circuit is opened and the light emitting element 13 is turned on.
Are prevented from being turned on to prevent wasteful consumption of power.
