Description

[Detailed Description of the Invention] The present invention relates to an information display device that is mounted on an instrument panel of a vehicle and quickly selects necessary information from among a wide variety of information and displays it to the driver.

Conventional information display devices of this type have been proposed in which a drum or endless film printed with characters and figures is rotated to selectively display the information, but the size of the drum-type information display device is limited. There is a limit to the amount of information, and even in information display devices that use endless film, the length of the film is limited, so the amount of information is insufficient and a tensioner, etc. is required. This had the disadvantage that the structure was complicated.

The present invention was developed in consideration of these points, and uses a single end film, and winds both ends of the film onto a spool. The purpose of the present invention is to propose a vehicle information display device which is provided with a biasing spiral spring to apply tension to the film, and this force is sent by a motor or the like, making it simple and capable of quickly displaying a wide variety of information selections. be.

The present invention will be explained in detail below based on embodiments shown in the drawings.

Reference numeral 1 denotes a long film with ends, on which a large amount of information in the form of figures and characters is printed in seven real shapes, and continuous perforations 1a are provided at the edges.

2 and 3 are spools;
Each end of the film 1 is fixed to the spools 2 and 3, and the film 1 is wound around the spools 2 and 3.

4 and 5 are contact-type spiral springs, the outer ends of which are held by a casing 6.7 fixed to the spools 2 and 3, and are wound and housed in the casing, and the inner ends of the springs are Since the springs 4 and 5 are fixed to the fixed parts 8 and 9 and are always trying to be released, a rotational torque in the direction of the arrow is always applied.

This torque allows the force using the contact type spiral spring, and the variation in the amount of film 1 to be pulled out to be relatively small.

Reference numeral 10 indicates an idle shaft 11 which is a sprocket as a driving device, and has a pawl 11a that engages with a perforation 1a of the film 1.

12 is a forward/reverse pulse motor that drives the sprocket.

13 is a pulse motor drive circuit, and 14 is a control circuit.

In the above embodiment, when a signal is input to one of the terminals 15 of the control circuit 14, the control circuit 14 outputs a pulse at an address corresponding to the signal, rotates the pulse motor 12 via the drive circuit 13, The film 1 is fed, and when the feeding stops, corresponding information is displayed on the window 16.

At this time, the spools 2 and 3 are always biased in the winding direction, so the film 1 slackens and the sprocket pawl 11
a The color perforation 1a does not come off or float out of the window 16, and the required information can be selected and displayed quickly and reliably, and speedy display of traffic information such as route guidance for vehicle drivers is required. It is extremely advantageous for displaying information such as power.

In the above embodiment, the pulse motor 1 is used to feed the film 1.
2 has been described, but instead of this, a binary code is printed for each frame of film 1, and this is read optically to control the DC motor and display the necessary information. Also, in this case, sprocket 11
The film may be fed by an epinch roller, or the film 1 may be projected and displayed on a screen.

As described above, the present invention includes an edged film 1 on which a large amount of information is attached using figures, characters, etc., and a method in which the film 1 is fed in the longitudinal direction and the feeding of the film is stopped when the necessary information is displayed. A vehicle information display device comprising a drive device 11 includes spools 2 and 3 that wind up both ends of the film 10, respectively, and spiral springs 4 and 5 that constantly urge the spools 2 and 3 to rotate in the direction in which the film is wound. The driving device 11 is adapted to act on the film 1 stretched between the spools 2 and 3.

That is, since the two spools 2 and 3 are always biased in the winding direction by the spiral springs 4 and 5, the film 1 is kept under tension even without a tensioner, and the claws of the sprocket 11, etc. It does not fall out of the window, can be quickly selected and driven, and can be displayed in close contact with the window 16.

Further, even when projecting and displaying on a screen, the focus will not be lost due to floating of the film 1.

There is no need to wind and drive the spools 2, 3 with a motor or install a slip mechanism, and the structure is simple, low in cost, and compact, making it suitable as an information display device for vehicles.
