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.
What is claimed is: 1. 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. 2. A system according to claim 1, wherein said operation control means includes a display signal generating circuit for generating a disply signal corresponding to the operation being performed by said recording or reproducing means.
SUMMARY OF THE INVENTION It is a general object of this invention to provide a recording or reproducing system which is capable of solving the above-stated problems of the prior art.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram showing in outline the arrangement of a VTR to which this invention is applied.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT In the case of the following description of an embodiment, this invention is applied to a VTR;, FIG. 1 shows in outline the arrangement of the VTR. The illustration includes the body 1 of the VTR; an operation part 2 arranged on the body 1 to permit an operation for starting a recording or reproducing operation; a body system controller 3 which is arranged to produce and supply an operation instructing signal C to a main system controller 5 in response to an operation performed on the operation part 2 disposed on the body 1 and to cause a display part 4 disposed on the body to make a display in accordance with a display instruction signal B received from the main system controller 5; and the display part 4 which is disposed on the body 1 and is arranged to be under the control of the system controller 3 disposed on the body 1. The main system controller 5 is arranged to produce a clock pulse signal A; to produce a display instruction signal B indicative of the operating state of a recording or reproducing part; to control the recording or reproducing part 6 according to an operation instructing signal C produced either from the above-stated body system controller 3 or from another system controller 9 which is remotely disposed; and to control exchange of various instruction signals between the system contollers 5 and 9 which are disposed on the body and at a remote location respectively. The recording or reproducing part 6 is arranged at the body of the VTR to perform recording or reproduction. A reference numeral 7 denotes a remote control part; and a numeral 8 denotes a remote operation part provided for causing the VTR body 1 to begin to record or from remote control part 7. The remote system controller 9 is arranged to produce and supply the operation instructing signal C to the main system controller 5 in accordance with an operation performed on the remote operation part 8 and to cause a remote display part 10 to make a display in accordance with a display instruction signal B produced from the main system controller. The remote display part 10 is under the control of the remote system controller 9. Numerals 11 and 12 denote OR gates. A numeral 13 denotes a switch which is arranged to close (be in ON state) when the remote control part 7 is connected to the body 1.
