Regardless of time or place,
It is increasingly being adopted in every field.

Therefore, information transmission through image processing has become widespread not only in leisure but also in business, and has come to be used not only for entertainment and educational information, but also for business information processing. As seen in the above, each seat with a television was widely adopted, and due to the implementation of the applicant's earlier invention, a personal type LCD television was installed in each seat, and it was possible to watch not only broadcast television programs but also videotapes. A variety of programs are now being aired.

By the way, it is normal practice for each seat of a vehicle equipped with such a personal type LCD TV, etc., to be operated again after a predetermined maintenance inspection when the vehicle reaches the terminal station from the starting station. From a vehicle's point of view, the direction of travel before and after maintenance and inspection at its terminal station will be changed.
As shown in the figure, when the direction of travel between the up and down directions is changed, the seating direction of a large number of seats 1, 1, etc. is changed. The front and back directions are changed by the rotation of the seat 1 through the bush bearings 2, 2, etc., and the direction of the seat is changed by rotating the front and rear inclination angle in the opposite direction. It was supposed to do the conversion.

There is a problem that a change in the seating direction is unavoidable, and therefore it is difficult to operate, and the seating direction is changed from the seating direction shown in Fig. 7 to the seating direction shown in Fig. 8 due to the change in the traveling direction of the train. When this is done, the televisions to be operated before and after the seating direction change are different, resulting in an inconvenience in that operations cannot be performed smoothly.

Accordingly, in personal televisions such as LCD televisions installed in passenger seats of Shinkansen cars, which have been recently implemented by the applicant's prior invention, seats have been developed in order to solve the troublesome operation of various switches associated with the above-mentioned seating changes. There is also a solution technique in which an operation panel is attached to the armrest 10 of No. 1 to make it easier to operate, but this new technique also allows the user to change the seating direction from the seating direction shown in FIG. 7 to the seating direction shown in FIG. 8. When the conversion is performed, the television 3 corresponding to the seat cushion of the seat changes, which has caused a problem in that the television to be viewed cannot be operated by operating the operation panel on the seat cushion.

<Object of the Invention> The object of the invention of this application is to solve the problems associated with changing the seating direction of personal type LCD TVs installed in passenger seats of vehicles such as Shinkansen based on the above-mentioned prior art. This is a technical issue that will allow the TV to be viewed to be operated comfortably without compromising one's sitting posture, and to be able to comfortably operate the television to be viewed from the seated position even when the seating direction is changed due to a change in the direction of travel of the vehicle. It is an object of the present invention to provide an excellent passenger seat structure with a television device that can be operated smoothly regardless of direction changes and is beneficial to the field of information processing technology application in the transportation industry.

In order to solve the above-mentioned problems, the structure of the invention of this application, which is based on the above-mentioned claims, is to solve the above-mentioned problems. Even if the front seat has a backrest or end wall, there is a specified LCD TV or other television set, and the TV can be operated by smoothly switching channels etc. from the control panel installed on the armrest of the seat. It is possible to perform the following operations, and
Even if the direction of the seat is changed or the backrest is tilted due to a change in the direction of travel of the train, the transmitter installed at the bottom of the seat cushion will be replaced by the receiver installed under the front seat cushion. A technical means that allows operation signals to be sent via a signal path using a wired or wireless method, and the viewing of television can be easily performed using infrared rays, ultrasonic waves, or in the case of a wired connection, via a connector connection. This study included the following.
