Description

  The present invention relates to a door phone with a camera installed near a front door to call a resident, and more specifically, with a camera with an improved arrangement of illumination provided to enable a camera to be captured by a camera even at night. It relates to the door phone slave unit.

As a door phone slave unit with a camera that is installed near the entrance door and calls a resident, a built-in LED as illumination is widely used so that visitors can be imaged even at night. In this case, what accommodated LED in the camera cover provided in order to protect a camera so that rainwater may not permeate from an LED installation part has prevailed.
However, when an LED is arranged in the camera cover, a situation occurs in which the light emitted from the LED is reflected by the camera cover and reflected on the camera. To prevent this, a rib is provided between the camera and the LED. Such a shielding member is provided to prevent the reflection (for example, see Patent Document 1).

Japanese Patent No. 2071025

  As a resident's request, the visitor wants to look at the camera so that the face of the visitor can be easily confirmed. However, as described above, the conventional doorphone with a camera has the camera and the LED installed close to each other. As a result, it was difficult for visitors to look directly at the camera because the LED light was so bright. In addition, since ribs and the like were separately provided to prevent the reflection on the camera due to the reflection of the camera cover, the configuration was complicated and the number of parts was increased.

  Therefore, in view of such problems, the present invention has an object to provide a door phone with a camera that can reduce the number of members without requiring a separate cover even if the illumination is moved from the inside of the camera cover to the outside. It is said.

In order to solve the above problems, the invention of claim 1 is directed to a camera for imaging a visitor, an LED for night illumination, a call button for a visitor to call a resident, and a visitor calling with a resident. A camera-equipped doorphone slave unit having a microphone and a speaker, wherein the LED is disposed on the back of the call button, and the call button is formed of a light-transmitting member that transmits light emitted from the LED. And
According to this configuration, since the LED is arranged on the back of the call button, it can be installed away from the camera without securing a separate illumination mounting area, and glare can be reduced. And since a camera and LED can be installed apart, the member which prevents the reflection to a camera becomes unnecessary. Further, since the calling button serves as a cover member for the LED, it is not necessary to provide a separate cover member for the LED.

According to a second aspect of the present invention, in the configuration according to the first aspect, the back surface of the calling button is subjected to diamond cutting, and light emitted from the LED is diffused and transmitted.
According to this configuration, since the light of the LED diffuses, the light can be irradiated over the entire imaging range of the camera, and an easy-to-view video can be captured. Further, the diamond cut makes it difficult to visually recognize the LED from the outside, which is also preferable in terms of appearance.

The call button is arranged at the lower end and the right and left ends of the fixed portion and the call button are connected by elastic pieces, while the energization display portion is between the left and right elastic pieces and is fixed to the fixed portion. It is characterized by being formed integrally.
According to this configuration, the call button member including the call button functions as a cover for both the LED and the light emitting unit of the energization display unit, and thus the number of members can be reduced. Furthermore, since an elastic piece is provided, a separate elastic member is not required.
In addition, since the energization display part is formed integrally with the fixed part, the energization display part does not move back and forth even when the call button is pressed and moved back and forth, and the energization display part is arranged near the call button. Even in this case, the light emission state of the energization display unit does not become unstable.

  According to the present invention, since the LED is arranged on the back of the calling button, it can be installed away from the camera without securing a separate lighting mounting area, and glare can be reduced. And the member which prevents reflection in a camera becomes unnecessary. Further, since the calling button serves as a cover member for the LED, it is not necessary to provide a separate cover member for the LED.
