A connector adapted to detect a connective state is disposed in a monitor having a video input terminal and display. The detector detects the presence of an external video output connected to the video input terminal. When a video input it detected, a power controller enables the video display; however, if no connection is detected to the monitor input, power to the display is disabled. According to one embodiment the detector determines the connective state based on the presence of a video signal input from the video input terminal. In yet another embodiment the control signal terminal is provided for connection with a video camera. In addition, video operation switch and output for controlling the video camera are also provided. Finally, the monitor may include an infrared controller for sending control signals to control the operation of the video camera.

Monitor with connector for detecting a connective state

A video camera connects a monitor with a camera body. A first multi-connector is connected to the camera body and includes a video output terminal for outputting a video signal to an external apparatus and a recognition output terminal for outputting a recognition signal in response to a ON/OFF state of the camera power. A second multi-connector is connected with the monitor, for connecting to the first multi-connector. The second multi-connector includes a video input terminal for inputting the video signal and a recognition input terminal for inputting the recognition signal from said camera body. A display is also provided for displaying an image based on the video signal inputted from the video input terminal of the second multi-connector and a power controller controls a monitor power to be ON/OFF based on the recognition signal inputted from the second terminal of the second multi-connector. In addition, the recognition output terminal of the first multi-connector is a power recognition terminal for outputting a power recognition signal designating whether the camera power is ON/OFF. Finally, the recognition output terminal of the first multi-connector is a control signal I/O terminal for inputting a control signal in conjunction with outputting a signal designating an operative state of camera. An operation switch operates the camera body and a control signal is output for to the control I/O terminal in response to operation of the operation switch. Also, a camera operation state displays an operative state of the camera based on the signal designating the operative state of camera inputted from the control signal I/O terminal.

Video camera with multi-connector for supplying video and power

Functions of a videocamera are extended by connecting accessories. A camera body recognizes which accessories are connected based on a recognition information designating sort of accessories inputted from an accessories recognition terminal of multi-connector when accessories are connected to the camera body through the multi-connector. The camera mode selects automatically an operation mode to suit with accessories connected among multiple operation modes including a camera mode and VTR mode. An operation of changing the operation mode by an operation switch on the side of the camera body will not be required.

Videocamera having a multiconnector connectable to a variety of

A thermal head has a plurality of heating elements disposed in line. These heating elements are grouped into sets of four heating elements. Each set records one pixel which is constituted by 4.times.8 cells disposed in a matrix shape. Each cell is selectively recorded with an ink micro dot. A blank section record an nth pixel, and immediately before each heating element faces the first main micro line of an (n+1)th pixel. In the course of this blank section, each time the thermal head moves by a predetermined distance, each heating element is driven by drive data which does not make the heating element turn on. In a preferred embodiment, if an nth pixel has a low density, each heating element is selectively driven to the extent that an ink micro dot is not recorded, so as to preheat the selected heating element in the course of the blank section.
