Abstract
Abstract A CRT monitor and accompanying control unit are described. The control unit is detachably mounted on the exterior of the CRT monitor. Video connectors on the monitor and control device are arranged to mat directly together when the control device is placed in position. This cuts down on electromagnetic interference normally associated with video cables, and reduces the numbers of cables which must be connected by the user.

Dependent Claim
90 words
A display terminal device as claimed in claim 7, in which the hook or hooks (24) are disposed such that when the control device is presented to the CRT monitor device for mounting thereon the hook or hooks pass through one or more corresponding support apertures (26); the arrangement being such that subsequent movement of the control device into latching engagement with the CRT monitor device simultaneously engages the hooks to support the control device on the CRT monitor device and connects the control device to the CRT monitor device.
Claim 10
Dependent Claim
75 words
A CRT monitor device (1) comprising: means for detachably mounting a control device for supplying video signals to the CRT monitor device, on the exterior of the CRT monitor device; and a video connector (4) for receiving the video signals, the connector being mounted on the CRT monitor device and being arranged to mate with a corresponding video connector (11) on the control device when the control device is mounted on the CRT monitor device.
Claim 11
Dependent Claim
75 words
A CRT monitor device (1) comprising: means for detachably mounting a control device for supplying video signals to the CRT monitor device, on the exterior of the CRT monitor device; and a video connector (4) for receiving the video signals, the connector being mounted on the CRT monitor device and being arranged to mate with a corresponding video connector (11) on the control device when the control device is mounted on the CRT monitor device.
Claim 12
Dependent Claim
25 words
A CRT monitor device as claimed in claim 9, in which the control device is detachably mounted on the underside of the CRT monitor device.
Claim 13
Dependent Claim
71 words
A CRT monitor device as claimed in claim 10, in which: said underside includes a bottom surface (13) and a surface (41) downwardly extending from said bottom surface; the top surface (9) and a further surface (5) of the control device are adjacent to the bottom surface and the downwardly extending surface respectively; and a video connector in said further surface mates with a corresponding connector in said downwardly extending surface.
Claim 14
Dependent Claim
72 words
A CRT monitor device as claimed in any of claims 9 to 11 in which, apertures (34,35) are provided in opposing surfaces of the control device and the CRT monitor device respectively, the arrangement being such that when the control device is mounted on the CRT monitor device the apertures in the opposing surfaces are aligned, thereby facilitating the flow of cooling air between the control device and the CRT monitor device.
Claim 15
Dependent Claim
34 words
A CRT monitor device as claimed in any of claims 9 to 12, including a latching means (24,26,29,30) operable to hold and support the control device in mounted position on the CRT monitor device.
