Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vehicle-mounted device, and more particularly to a vehicle-mounted device that reproduces images using a recording medium.

(Prior Art) In recent years, as cars have become more popular, not only televisions but also various in-vehicle recording and/or playback devices have come to be installed.
Directing the driver's eyes in that direction not only causes a danger due to the driver's attention being divided and loss of concentration, but also results in wasted power and unnecessary wear and tear on the head and disk.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide an on-vehicle device whose drive is automatically stopped while the vehicle is running or when the speed exceeds a predetermined speed condition.

[Means for solving problems]

In order to achieve such an object, the present invention provides a means for reproducing image information from a recording medium on a display means, a means for detecting a running state of a vehicle, and a means relating to the detected running state of a vehicle. and means for prohibiting display of image information on the display means.

(Function) In the in-vehicle device of the present invention, when the vehicle is running at a high speed, for example, the image information display prohibition means prevents image information from being displayed on the display means, thereby distracting the driver. It is possible to prevent this from happening, and also to suppress wasteful power consumption and equipment wear and tear.

〔Example〕

Embodiments of the present invention will be described in detail and specifically below based on the drawings.

FIG. 1 shows an embodiment of the present invention, in which 1 is a video floppy as a recording and reproducing medium, and 2 is a slot ink drive recording and reproducing machine (hereinafter referred to as a recording and reproducing device) having a slot 3 for inserting the video floppy 1. This is called a second chance). Video floppy 1 is a built-in disk, such as magnetic disk 4.
At its center, a center core 5 is provided to which a spindle motor provided on the recorder/player 2 side is fitted. Reference numeral 6 denotes a shutter, and during recording and reproduction, the shutter 6 slides to expose a portion of the disk 4, thereby allowing a magnetic head (not shown) on the recorder/player 2 side to perform recording and reproduction.

7 is a television, 8 is a signal line between the recorder/player 2 and the television 7, and 9 is an in-vehicle power supply. In this example, a switch means 1 is provided between these power supply lines IOA and IOB.
1 is interposed, and this switch means 11 is connected to the handbrake 1.
2 to make them interlock.

To explain the operation of the in-vehicle recording and reproducing apparatus configured in this way, as long as the vehicle is maintained in a stopped state by applying the handbrake 12, the power lines IOA and IIB are maintained in the connected state in the switch means 11. As a result, the recorder/player 2 and the television 7 are ready for operation. Therefore, when the video floppy 1 is inserted into the slot 3 of the recorder/player 2, the magnetic disk 4 is exposed by the movement of the shutter 6, and the playback image information is output to the television 7 in the playback mode by driving the spindle motor. If it is in recording mode, it will go into standby mode.

Next, when the handbrake 12 is returned to start the car from a stopped state, the switch means 11 is cut off in conjunction with the handbrake 12, the TV 7 is stopped even if it is showing a video, and the side of the recorder/player 2 is turned off. Also, the drive of the spindle motor is stopped.

FIG. 2 shows another embodiment of the invention. Originally, the recorder/player 2 includes a servo circuit 14 for driving the spindle motor 13 and a system controller 15, so in this example, a signal indicating whether or not the handbrake 12 is applied is supplied to the system controller 15. However, the spindle motor 13 is turned on and off through the controller 15 based on the signal, and similarly, the recorder/player 2 and the television 7 can be used only when the car is stopped.

3 and 4 respectively show two other examples of the present invention, in which the switch means 11 is turned on and off in relation to the speed sensor 20, and FIG. Similarly to the above example, the spindle motor 13 is turned on and off in conjunction with the speed sensor 20. That is,
The speed sensor 20 detects the running state of the car, and when the speed reaches such a point that the driver's distraction is unacceptable, the use of the recorder/player 2 and the television 7 can be automatically prohibited.

Although not shown, in order to further ensure safety while driving, signals from both the handbrake and the speed sensor are input to the AND gate instead of relying solely on the speed sensor. The output may be used to control the on/off of the power supply or the spindle motor as described above. Furthermore, it is also possible to connect the television and the recorder in series with a power source so that the television and the recorder are turned on and off simultaneously according to the conditions described above.

The present invention is applicable not only to in-vehicle playback machines, recorders, and record/playback machines that use disc-shaped record carriers, but also to visual information providing means such as cathode ray tubes and liquid crystal display tubes, such as in-vehicle video tapes. This is also possible for recorders, etc., and the present invention prohibits the use of this type of equipment in order to ensure safety while the vehicle is running, especially when traveling at high speed.

(Effects of the Invention) As explained above, according to the present invention, the running state of the car,
For example, when the car is running at high speed, the driver can concentrate on driving by cutting off the power supply to the recording/reproducing device or stopping the rotation of the spindle motor so that the reproduced image is not displayed on the display means. In addition to this effect, it can also contribute to energy saving by turning off the power, suppressing temperature rise, and preventing wear and damage to the seat and head by stopping rotation of the spindle motor.
