Abstract

PURPOSE:To confirm a visitor by providing a means for swinging an image pickup camera vertically/horizontally from a master set side to change the direction of the camera freely from the indoor side. CONSTITUTION:The image pickup camera 2 is contained at the upper part of a housing 1 and a talking unit 3 is contained respectively to the lower part. When a handset 6 is hooked off by a master set 5, the talking with the indoor side is attained. An infrared emitting diode 10 is arranged at both sides of the image pickup camera 2 and an intermission current synchronously with a video synchronizing signal of the camera 2 is fed to the diode 10 by the operation of a pushbutton 4 and infrared rays are irradiated on a visitor through a blind cover 11 comprising an infrared transmission filter on the front face. Thus, image pickup is attained without being noticed by the visitors at night. The camera 2 and the diode group 10 are fixed to a moving frame 12 and the moving frame 12 is driven by motors M1, M2 horizontally and vertically.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a door phone with a monitor camera that allows a visitor to make a call while monitoring the image of the visitor.

[Background Art 1 Door phones with integrated monitor cameras have been proposed. FIG. 3 shows one example, in which an imaging camera 2 and a communication unit 3 are housed in the same housing 1, and a visitor M operates a push button 4 provided at the bottom of the housing 1. From 1, the door phone I installed in the room
A call is made to the telephone number n5, and the parent 8!5 picks up the handset 6 to make the call, and is also able to confirm the visitor on a monitor screen 7 made of liquid crystal or the like. However, in such conventional examples, the angle of view of the lens is uniquely determined by L, where the direction of the imaging camera is fixed. Additionally, if the visitor is a child or short, the visitor's face may not be visible on the monitor screen.

[Object of the Invention] The present invention has been made in consideration of the above-mentioned problems, and its object is to provide a doorbell with a monitor camera that allows the direction of the imaging camera to be freely changed from inside the room. We are here to provide you with the best possible results.

[Disclosure of the Invention] Accordingly, the present invention houses an imaging camera and a telephone call unit in the same housing, and enables a call between the camera and the telephone base unit located indoors by operating a push button provided on the front of the housing. In addition, in a configuration in which the visitor's image based on the above-mentioned imaging power can be monitored from the main unit side, a means is provided for swinging the imaging camera up, down, left and right from the main unit side, and the visitor usually Since visitors are not aware of the built-in camera, they do not necessarily have to stand directly in front of the doorbell.In such cases, visitors can change the direction of the camera to see the visitor's face. be.

[Embodiment] Figure 1 shows an embodiment of the door phone according to the present invention. In the figure, an imaging camera 2 using a solid-state image sensor is housed in the upper part of the housing 1, and a dual-talk unit 3 is housed in the lower part, and a push button for calling the parent 8!5 is housed in the lower part of the housing 1. 4 is provided. When the handset 6 is lifted up on the base unit 5, the speaker 8 and microphone 9 enable communication within the room. An appropriate number of infrared light emitting diodes 10 are arranged on both sides of the imaging camera 2, and when the push button 4 is operated, an intermittent current synchronized with the video synchronization signal of the imaging camera is supplied to the light emitting diode 10 for a certain period of time. The visitor is irradiated with infrared rays through the blind cover 11 made of an infrared transmission filter on the front, and images can be taken without the visitor noticing even at night.

The imaging camera 2 and the light emitting guide group 1o are fixed to a movable frame 12, and as shown in FIG. tjS2, the movable frame 12
is rotated upwardly and horizontally within a fixed angle range by two motors M+1M2. That is, as shown in FIG. 2B, the movable frame 1 is further attached to the intermediate frame 14 which is pivotally supported by the fixed frame 13 and rotated by the motor M1.
2 is pivotally supported, and this movable frame 12 is rotated by a motor M2. The motor M19M2 is composed of a C motor with forward and reverse j+f functions, and is controlled by a four-way lever switch 15 as shown in FIG.
It is operated while looking at the

[Advantageous Effects of the Invention 1] As mentioned above, the present invention provides a doorbell with a monitor camera equipped with a communication unit and an imaging camera (in which a means for swinging the imaging camera vertically and horizontally from the indoor side is provided). The advantage of this feature is that you can change the direction of the camera to see the visitor's face if the visitor is standing away from the front of the doorbell, or if the visitor is a short child. It also allows you to operate the force/arm while looking at the monitor screen.
It has the advantage of being extremely easy to operate, ■ and χ7
