Description

DETAILED DESCRIPTION OF THE INVENTION This invention is one of the features that allow data to be imprinted. - Regarding cameras, sometimes the control circuit that controls the operation of each mechanism necessary for photographing is connected to an external power source via an endoscope, or an electric wire is supplied from an adapter with a power source. Of the 4 JIs that can be imprinted with data configured to
This relates to the T-camera 2.

As is well known, inside a hollow body such as a body cavity or a chin organ,
-*The endoscope used for observation is II! An endoscope that is used not only for II but also for taking and recording photographs, and for this purpose, it is detachably attached to the eyepiece of the endoscope and can be used to take photographs for family celebrations. A camera is provided. In this type of endoscope camera, a control circuit that controls the operation of each shutter mechanism, such as the shutter and film winding mechanism necessary for photographing, is connected to an external power source through the endoscope. Generally, the device is configured to receive power from an adapter that has a power supply. Furthermore, as importance has been placed on the ability to record images through close-up photography, there is a demand for an endoscope camera that can imprint photographic data such as the date of photographing on a portion of the subject image. And in response to such requests,
An endoscope camera capable of data imprinting is provided, and the data imprinting means built into the camera is to transfer a data image formed by a data carrier into a viewfinder based on a data imprinting beam Ω illumination light. There is a known device which is capable of mistaking and guiding the data image to a part of the film surface when photographing a subject.

Endoscopic cameras are designed to be used for endoscopic examinations that are difficult to perform in endoscopic examinations or to examine the inside of body cavities. It is desired that the device always operate normally, and for this reason, it is desirable that the cause of the failure can be quickly determined in the event of a failure.

Therefore, this invention was developed based on the above-mentioned problem, and uses the data imprinting light source of the company data input means to check whether there is any abnormality in the power supply circuit from the external power supply, which is one of the causes of failure. Endoscope camera 2
T-What we offer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An endoscope camera capable of imprinting data according to the present invention will be described in detail below based on an embodiment shown in the accompanying drawings.

In Fig. 1, A indicates the eyepiece of the endoscope, and B indicates the internal AW camera. It is possible to attach and detach the XB. The eyepiece has power output terminals 1a and 1b connected to an external power source (not shown). On the other hand, the camera BK has power input terminals 2m and 2b which are connected to a control circuit 3, which will be described later, and are connected to the control circuit 3, which will be described later, by the coupling means described above! & eyes@AKfi When the power input terminals 2a and 2b are connected to the [Su output terminals 1m and 1]
bK * is configured to be continued. Refreshingly, when this camera B is attached to the above eyepiece, # (not shown) of the endoscope is visible! The detection optical system is optically convoluted and the I
A photographic lens 5 that forms an image of the object (411), and a film 4 disposed between the photographic lens 5 and the film 4.
Photographing optical path t to the finder optical system consisting of a condenser lens 6, a pentaprism 7, and a mirror lens 8 fI! It has a mirror shutter 9 that is controlled to move between an observation position indicated by a solid line for guiding the image and a photographing position indicated by a broken line until a predetermined appropriate exposure time elapses during photographing. Furthermore, Jin's camera B has a data imprinting light source 101 consisting of a light emitting diode or a rung, and an external operation knob 11 (knurls are formed on the surface portion and the top surface portion, respectively) to direct the illumination light from this light source 10 to the light source 101. Mechanism III from above
A light guide member 13 that leads to a well-known data carrier 12 consisting of a transparent I# part and an opaque part set by
, the data image formed by the illumination light transmitted through the data carrier 12 (i-film or refracted by the mirror shutter 9 and guided to the finder optical system by the mirror 14 and the imaging lens 15, and further by the light beam). It has a data imprinting means consisting of a lighting window 16 for inputting external light for forming data 11IIt instead of the illumination light of 01110 and the like.

Incidentally, the upper ml light guide member 13 has an extension line of a trapezoidal prism (
Means such as a combination of mirrors may also be used. ) formed light $
A reflection surface m13a is provided between the lighting window 16 and the data carrier 12 in order to make the illumination light of 10 years or more pass through the same optical path as the external light entering from the lighting window 16, but this reflection surface 131 is formed as a total reflection surface. The light source 10 may be one that can leak illumination light from the light source 10 and transmit external light. The light source 10 is configured to be turned on by energizing a well-known control circuit 3 that controls the movement of the mirror shutter 9 and the film winding mechanism (not shown).

It is configured as above and 4 out of 9 data can be imprinted!
- By attaching the camera to the eyepiece A of the endoscope, it connects the power output terminals 1a and 1b and the power input terminals 2a and 2b.
A power supply circuit between a power supply (not shown) and the control circuit 3 is formed. Then, by turning on the power and energizing the control circuit 3, the data imprinting light source 10 is turned on. By lighting the light source 10, the data carrier 1
The data conductor formed by mirror 14 . In addition to being displayed in the finder through the Keiken Shins style finder optical system, the illumination light from the lighting of the light source 10 leaks from the reflective surface 13a of the original guide member 13, so the above-mentioned information is displayed from outside the camera through the lighting window 16. The state where the light (110 can be ensured) is lit.

Become. In this state, it is possible to confirm whether the setting data is set to desired data and to confirm that power is being supplied to the cape control circuit j13 reliably. After this M7, by performing a shutter release operation, it is possible to record the data 1lt-film 4 together with the similar shutter tm1MIL object image.

As mentioned above, according to the endoscopic camera according to the present invention, which allows data to be read, data can be set using a lighting window or a viewfinder for confirming data settings based on external light inside the viewfinder. Since the light source for data imprinting is turned on by external power supply before one shadow, it is possible to ensure that power is being supplied, so whether or not there is an abnormality in the power supply circuit from the external power supply. It is possible to determine this and check the power supply circuit, which is one of the causes of failure. Note that the check can be made in the same way by providing a display window in place of the lighting window to confirm whether the light source is turned on.

According to the Oti1g camera, it is used to check the power supply circuit of the light source for data imprinting, and it is also used for the display part of the existing finder optical system and lighting window t check, so it is advantageous in terms of cost. Therefore, the effects of this woodcutter's internal vision camera on consideration and use.
iIt's extremely big.
