Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a remote control device.

[Summary of the invention]

This invention provides a remote control device in which a coated control j111 signal is transmitted from a controller to a controlled device, in which a signal indicating the operating mode of the controlled device is converted into nits and transmitted to the controller side. By displaying the operating state of the controlled device on a display means designed to prevent malfunctions, it is possible to reliably remotely control a wide variety of operating modes.

[Prior Art] As a headphone two-center player (hereinafter simply referred to as a "player") such as the Walkman (registered trademark),
A control operation unit (commander) is provided between the conductor (wire) connecting the player and the headphone, so that the player's operation, playback volume, etc. can be controlled by hand. A remote control type is known.

FIG. 2 shows the appearance of an example of this type of player.

In the figure, (1) is a player, and a jack (2) is provided on an appropriate side of the player, and a plug (3) is connected to the jack (2).
is pushed in. The plug (3) and the commander (4) are connected by a conductor (5), and then by another conductor (6), the commander (4) and headphones (7) are connected.

Then, in the player (1), the tape “Kasento” (
Left and right channel stereo audio signals 11. When R is regenerated, this signal "C1" is transmitted through the commander (4) and the conductors (5) and (6).
However, the left and right acoustic unisoto (7L) of the headphones (7)
), (7R).

In this case, the commander (4) can be, for example, less than half the size of a business card.

Therefore, if you want to play a tape while commuting, for example, on the train, you can put the player () in your bag or bank, put the commander (4) in the chest pocket of your jacket, or use a clip. It is used by fastening it to a collar or necktie.

[Inventive power Moe 1: Decide and try-jru section] By the way,
Conventional RI 12-1=・Remoni 1 type player is as follows: ■ Friend and right channel a) Voice transmission line G
Each control signal of the internal law is increased by one time, ■ = 1-
The number of operations and the player's movement is expressed as a sentence J k+
Various control methods are employed, such as (1) providing operation keys and transmission lines for each operating mode.

However, in a wired lead-type player as described in Section 2, the number of leads that can be practically controlled is limited to about 1" at most, and there is little development potential. There was victory.

In addition, the former two had a shield against malfunction or erroneous operation.

In view of this, the present invention provides a wide variety of controls.
This paper attempts to propose a remote control device that can prevent malfunctions.

[Means for Solving the Problems] The present invention transmits an encoded display signal from a controller (4) including operating means (43) to (45) and an encoding means (42), (21) Controlled 11 devices including (1)
In the same remote control device that controls the operating state of the device, a second device is connected to the controlled device. In addition to installing a third encoding means (22), the controller is also provided with a second decoding means (42) and a display means (50), and a coded display corresponding to the operating state of the controlled device is provided. This is a remote control device that transmits signals and displays the operating status of the controlled device on the display means of the controller 711.

Next, the operation of this embodiment will be explained.

First, the power switch (36) is turned on on the player (1) side, and both system control circuits (20) and (40) are turned on.
) is supplied with electric light (heavy pressure), and the player (1) enters a standby state.

In this standby state, play Pokun (43) on the commander (4) side.
, ), the iJTJ playback command signal encoder (41)
is supplied and coated. This encoded reproduction command signal is decoded by the tick 1 reader (21) on the player (1) side to obtain the original reproduction command signal.

In the system control circuit (20), a regeneration mode control signal corresponding to this regeneration command signal is formed and a solenoid (3) is generated.
1), and the reproduction head (111,), (11,1
? ) is brought into contact with the tape MT, and the pinch roller (34>) is brought into rolling contact with the capstan (33).Furthermore, in conjunction with this, the switch (35) is turned on, and the fixed position (37) is brought into contact with the pinch roller (34>). The voltage passes through the switch (35) to the regeneration circuit (
10) and is also supplied to the motor (32), so that the player (1) becomes a playback mode. Note that this state is maintained by a control mechanism (not shown).

When in this play mode (and other operating modes), pressing the stop button (43,) will cause Henod (IIL) (11,
, R) and the pinch roller (34) return to the stop need, and the switch (35) is turned off and the regeneration circuit (10) and motor (32) become inactive. Player (1) is in stop mode 1.

In the playback mode, various characteristic command signals transmitted from the commander (4) side in the form of 2J codes are transmitted from the commander (21) side.
), and based on this, various characteristics of the reproducing circuit (10) are set.

In this embodiment, various command signals obtained by the decoder (21) are encoded again by the encoder (22) and sent back to the commander (4) side, so that the setting states of the various characteristics and the player (1) can be changed. The fact that the device is in playback mode is displayed on the liquid crystal display (50).

In addition, when the playback button (23□) or changeover switch (24,) to (24n) on the player (+) side is operated, the corresponding command signal is encoded by the encoder (22) in the same way as described above. The status of the player (1) is displayed on the display (50). This allows the user to correctly recognize the operating mode of the player (1) and the setting states of various characteristics.

When the player (1) is in playback mode, the commander (4)
) is pressed, a reproduction command signal is supplied from the control circuit (40) to the control circuit (20).

This control circuit (20) determines that the reproduction command signal is supplied and that the player (1) is in the reproduction mode, and then, via a running direction reversing mechanism (not shown),
Reverse the running force of the tape MT.

Player (1) is then still in playback mode.

For example, when playing a tape, if you want to play a part that is far away from the part that is currently being played, use Commander (4).
fast forward button (43,) or rewind button (433)
) will be operated. In this case, both buttons (43,) and (43
3) must be selected, but in this example,
Indicator (50) for tape running direction or commander (4) side
Since it is displayed at the top, it is possible to perform fast forward or rewind operations without error.

In the case of other operation motes, the operation state of the player (1) is set based on the operation on the commander (4) side, and information on this operation state (display information) is transmitted to the commander (4) side. , is reliably displayed on the display (50)l.

Further, since command signals and display information are encoded and transmitted, remote control of a variety of devices can be performed.

In the above description, the player (1) is a cassette player, but it may be a CD player, a DAT player, or the like. Furthermore, although the above-mentioned embodiment is applied to a batting line system, it can also be similarly applied to a wireless system by, for example, frequency-multiplexing the coded signal with an audio signal in an ultrasonic band.

〔Effect of the invention〕

As described in detail above, according to the present invention, a coded control signal is transmitted from the controller to the controlled device, and a signal indicating the operation mode of the controlled device is encoded and transmitted to the controller side. In addition, since the operating mode of the controlled device is displayed on the display means provided in the controller, a remote control device that can prevent malfunctions and reliably remotely control a wide variety of operating modes can be obtained. .
