DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concealed photographing apparatus in which a camera is fixed in a portable small bag with a camera facing a through hole formed in a side wall thereof and a recorder is housed therein.
Used for tracking.

[0002]

2. Description of the Related Art As this kind of concealed photographing apparatus, there is used a concealed photographing apparatus in which a photographing apparatus is housed and fixed in a bag held by a small side such as a pouch, a second bag, and a handbag. However, in this device, since the operation switches for the power supply, recording, sound, etc. of the imaging device are present on the main body side, that is, inside the back, the back must be opened and closed at the time of operation, and during tracking and investigation, Recording timing may be missed. Although it is sufficient to keep the recording state at all times so as not to miss the recording timing, since the portable recorder is operated by the battery, the battery is wasted considerably. In order to secure the shooting time using the battery, it is necessary to easily turn on and off the power supply whenever necessary to perform the recording operation.

[0003] In the conventional concealed photographing apparatus, a monochrome camera apparatus and a color photographing apparatus are separately used. Recording by the latter device has a high evidential ability, but when the power consumption is large and the illuminance of the subject becomes less than about 2 lux, the photographing becomes impossible. Although the former device consumes less power and can shoot sufficiently even with illumination of about 0.2 lux,
There is an inconvenience that the evidence capacity is reduced by the limited color. In confidential photographing, photographing is required regardless of day or night. However, it is inconvenient to prepare two photographing devices, and at present the confidential photographing is hindered.

[0004]

The present invention is directed to a confidential photographing apparatus in which a camera is directed to a through hole formed in a side wall of a portable small bag and a recorder is housed, and a recording operation can be performed efficiently and unobtrusively. Is the first task,
Another object of the present invention is to make it possible to shoot in response to a change in illuminance of a subject.

[0005]

[Technical Means] The technical means for solving the first problem is as follows: (a) The recording switch is also used as a power switch,
(B) The recording switch is arranged inside or below the lower part of the side wall of the back so that the recording operation can be performed from outside the back wall. It is customary to carry a small portable bag while holding it under its side, and in this state, the palm and the fingers are in a positional relationship of wrapping around the bottom of the bag. In the present invention,
The switch is shared with the power switch and one switch
In addition, since it is located inside the bottom of the back or the lower part of the side wall, the recording switch is operated by a natural operation from outside the back using the finger holding the back.
Can be drawn . Therefore, the photographer does not notice the recording from the subject side, and furthermore, the recording switch is not operated .
Since the operation can be performed for a necessary time, power can be used efficiently.

The technical means for solving the second problem is that in addition to the above technical means, two through holes are formed, and a monochrome camera and a color camera are arranged to face each through hole. Interposing a camera changeover switch between the camera and the recorder. Since the monochrome camera and the color camera are arranged and fixed to separate through holes independently,
Shooting can be performed without moving the camera.
Since the changeover switch of the camera may be interposed between the camera and recorder, in response to the illuminance of the subject switching Sui
By operating the switch, the camera to be used can be changed.

The concealed photographing apparatus is used in a state where the photographing environment does not suddenly change, such as during the daytime or at night, that is, in a state where the illuminance of the subject does not largely change. Even if the changeover switch is positioned inside the back, no great trouble occurs. Rice cake
N, similarly to the recording switch and keep to be operated from the outside of the back wall by placing the camera change-over switch at the bottom of the back or inside of the side wall lower, operating the switching換自body of the camera without noticing subject It is possible to cope with a sudden change in illuminance (claim 3). Furthermore, if an illuminance detection means for the subject is attached and the monochrome camera and the color camera are automatically switched according to the detection signal, even if the illuminance of the subject changes during tracking, it is instantaneous at the time of switching. Although photography is stopped, almost continuous video can be recorded (claim 4).

[0008]

As a result, the recording operation can be performed efficiently and inconspicuously. As a result, there is an advantage that natural concealed photographing is performed and an image with high evidence ability can be obtained. In addition, as a result of being able to cope with a change in the illuminance of the subject by switching cameras, there is an advantage that a single photographing device can photograph without missing a recording opportunity.

[0009]

1 and 2 show a concealed photographing apparatus according to the present invention, in which a pouch type back 1 made of leather or synthetic leather is used.
Three through-holes 2, 3 and 4 with a diameter of about 3 mm
, And the photographing input unit 5 is arranged and fixed inside. In the photographing input unit 5, a monochrome camera 6 having a lens having a diameter of 2 mm directed to the through hole 2, a color camera 7 having a lens having the same diameter directed to the through hole 3, and a directional microphone 8 disposed toward the through hole 4. Are housed, and operate by using the battery 11 as a power source. The monochrome camera 6 and the color camera 7 are selectively used by being switched by a switch 9 provided in the photographing input unit 5. Note that the through hole 4 is unnecessary when the microphone is attached to the tie pin and the sound is input remotely by being positioned outside the back 1.

The recording switch 10 is arranged on the lower surface of the photographing input unit 5, and no reinforcing plate is provided on the bottom surface of this portion so that it can be operated from the bottom surface of the bag 1. When this switch is turned on, the camera 6 or 7 that has been selected by operating the switch 9 in advance operates, and recording with the microphone 8 starts. At this time, the recording unit 15 operates using the battery 16 as a power source, and the content photographed by the camera is converted into a video signal, sent to the recording unit 15 using the lines 12 and 13, and recorded on a video tape. Will be. Note that a control unit 17 is housed between the recording unit and the bottom surface of the bag 1 so as to control photographing, recording, reproduction, history operation, and the like.
