摘要： A speaker system removably attachable to a video monitor is described which would eliminate the complexity in mounting the speaker system as an add-on unit as well as the ungraceful appearance of the video monitor when the speaker system is removed. The top side of a case incorporating speakers is formed to match the shape of the bottom of the front panel of the video monitor. The speaker system can be mounted on the bottom of the front panel of the video monitor, which is supported on top of a base, as a locking member formed on the top of the case is engaged with a locking hole formed in the bottom of the front panel, or a locking member formed on the bottom of the front panel is engaged with a locking hole formed in the top of the case. Due to lightweight and compact construction, the speaker system can be integrally mounted on the video monitor by using dead space formed between the video monitor and its base and it can be easily removed therefrom.

摘要： When a “screen saver” operates to display a homogeneous black picture image after the same image is continuously displayed on a CRT for a predetermined period of time, a power supply for a CRT display unit is controlled to be turned off, thereby preventing the CRT display unit from being left for a long time in a power-on state. Namely, a waiting time of 3 minutes, for example, is provided when the “screen saver” operates so that the CRT displays a homogeneous black picture image to turn off a power circuit for the CRT, and then a heater for the CRT is turned off after a lapse of a predetermined period of time of 5 to 60 minutes, for example. An extension graphics board, which is inserted in an open slot provided in a computer of an open architecture type may be provided to perform this function. The extension graphics board has an input detection part including a keyboard access detection part for detecting an address signal which is supplied to an address bus in response to manipulation of a keyboard, and an interruption request detection part for detecting an interruption signal which is output in response to manipulation of a mouse. A timer is reset when the input detection part detects the presence of an input signal received from the keyboard or the mouse. When no reset signal is supplied from the input detection part again before a lapse of a period of time which is previously set in the timer, a blank signal is supplied to the CRT display unit.
