Abstract

Abstract A combination device having a magnetic recording and reproducing unit and an electronic tuning type receiver, where the channel presetting switches of the electronic tuning type receiver also can act as the operating switches of the magnetic recording and reproducing unit. The electronic tuning type receiver is of the type which is tuned by control signals provided to a tuning means by a plurality of channel selecting switches. A selection circuit is interposed between the tuning means and the plurality of channel selecting switches and provides the plurality of control signals to the tuning means when a selection switch is in a first binary state, and provides the plurality of control signals to a tape-control section when the selection switch is in a second binary state. The tape-control section, in response to the plurality of control signals, controls the mode of operation of the magnetic recording and reproducing unit, and also provides a signal indicating the mode of operation to a sensing circuit. The sensing circuit, in turn, provides mode signals to a digital display unit which can visually display the mode of operation when the magnetic recording and reproducing unit is being used, as well as can visually display the station frequency or the like of the selected station when the electronic tuning type receiver is being used.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 144 words
In a combination of an electronic tuning type receiver and a magnetic recording and reproducing unit, wherein said electronic tuning type receiver is of the type which is tuned by control signals provided to a tuning means by a plurality of channel selecting switches, the improvement comprising: a. selection circuit means interposed between said tuning means and said plurality of channel selecting switches for providing said plurality of control signals to said tuning means when a selection switch is in the first binary state, and for providing said control signals from said plurality of channel selecting switches as a second set of outputs when said selection switch is in a second binary state; and b. tape-control sensing means responsive to said second set of outputs for controlling the operation of said magnetic recording and reproducing unit in accordance with said second set of outputs.
Claim 2
Dependent Claim 144 words
In a combination of an electronic tuning type receiver and a magnetic recording and reproducing unit, wherein said electronic tuning type receiver is of the type which is tuned by control signals provided to a tuning means by a plurality of channel selecting switches, the improvement comprising: a. selection circuit means interposed between said tuning means and said plurality of channel selecting switches for providing said plurality of control signals to said tuning means when a selection switch is in the first binary state, and for providing said control signals from said plurality of channel selecting switches as a second set of outputs when said selection switch is in a second binary state; and b. tape-control sensing means responsive to said second set of outputs for controlling the operation of said magnetic recording and reproducing unit in accordance with said second set of outputs.
Claim 3
Dependent Claim 54 words
The combination unit as recited in claim 1, wherein said modes of operation of said magnetic recording and reproducing unit controlled by said tape-control sensing means in accordance with said second set of outputs include the fast forward mode, the rewind mode, the eject mode, the first-speed play mode, and the second-speed play mode.
Claim 4
Dependent Claim 29 words
The combination unit as recited in claim 1, further comprising digital display unit means responsive to said tuning means for visually displaying selected channel information in a predetermined fashion.
Claim 5
Dependent Claim 79 words
The combination unit as recited in claim 3, wherein said tape-control section means further provides an output signal having information indicative of said second set of outputs, wherein said digital display unit means is responsive to a plurality of mode signals for visually displaying said mode signals in a predetermined fashion, and further comprising sensing circuit means responsive to said output signal of said tape-control section means for providing said mode signals having information indicative of said output signal.
Claim 6
Dependent Claim 35 words
The combination unit as recited in claim 4, wherein said digital display unit includes a plurality of visual display elements disposed from left to right with respect to the front of said digital display unit.
Claim 7
Dependent Claim 84 words
The combination unit as recited in claim 5, wherein said visual display elements are lighted in a designated fashion in accordance with said mode signals such that a visual display element to the right of a center point is lighted when said magnetic recording and reproducing unit is in a forward mode of operation and such that a visual display element to the left of a center point is lighted when said magnetic recording and reproducing unit is in a reverse mode of operation.
Claim 8
Dependent Claim 40 words
The combination unit as recited in claim 6, wherein the absolute distance of said lighted visual display unit from center point is in accordance with the absolute value of the speed of said forward or reverse mode of operation, respectively.
