Abstract

A system for recording and reproducing includes a first instruction and display device, a second instruction and display device separably electrically connected with the first such device and sensing apparatus for detecting whether the second device is connected to or disconnected from the first device. A recording/reproducing controller is operably responsive to instructions generated by the devices to operate a recorder/reproducer unit and is dependent on the sensing apparatus for controlling the displays of the first and second devices. In a VTR application, the first device is included in the body of the VTR and the second device is a remote controller. The sensing apparatus detects when the remote controller is operatively connected to the VTR and the controller provides for activation of the display of the remote controller under such condition.

Dependent claims

A recording or reproducing system for recording information on a recording medium or for reproducing information from a recording medium on which said information is recorded, comprising:

(a) recording or reproducing means for recording means for recording information on a recording medium or for reproducing information from a recording medium on which said information is recorded;
(b) operation control means for controlling the operation of said recording or reproducing means;
a first unit having
(c) first instruction means for instructing said operation control means to perform a control operation;
and
(d) first display means for making a display corresponding to a state of operation performed by said recording or reproducing means according to the instruction of said first instruction means;
a second unit for electrical connection to and disconnection from said first unit, said second unit having
(e) second instruction means for instructing said operation control means to perform a control operation;
and
(f) second display means for making a display corresponding to a state of operation performed by said recording or reproducing means according to the instruction of said second instruction means;
said system further including
(g) sensing means for sensing connection or disconnection of said first and second units;
and
(h) display control means operably responsive to said sensing means for controlling at least said second display means to present a display corresponding to the operating state of said recording or reproducing means corresponding to the instruction of said second instruction means when said sensing means senses connection of said first and second unit.

A recording or reproducing system for recording information on a recording medium or for reproducing information from a recording medium on which said information is recorded, comprising:

(a) recording or reproducing means for recording information on a recording medium or for reproducing information from a recording medium on which said information is recorded;
(b) operation control means for controlling the operation of said recording or reproducing means;
a first unit having
(c) first instruction means for instructing said operation control means to perform a control operation;
and
(d) first display means for making a display corresponding to a state of operation performed by said recording or reporducing means in accordance with the instruction of said first instruction means;
a second unit physically movable relative to said first unit for remote location with respect thereto, said second unit having
(e) second instruction means for instructing, from a distance farther than said first instruction means, said operation control means to perform a control operation;
and
(f) second display means arranged to make a display corresponding to a state of operation performed by said recording or reproducing means according to the instruction of said second instruction means when the instruction for an operation is given from said second instruction means to said operation control means said operation control means being operable further for controlling said first and second display means for selective display by said first display means and not by said second display means.
