Apparatus for projecting image from a model vehicle

Abstract

A model apparatus is provided in that images from a model vehicle can be continuously watched on a monitor even when the model vehicle travels through a place surrounded by a shielding material. An image signal transmission route from the model vehicle to the monitor uses conductive rail lines for guiding the model vehicle and supplying drive power to a drive motor, so that even when there is an electromagnetic shielding material in the vicinity of a place where the model vehicle travels, the images can be continuously displayed on the monitor.

Description

INCORPORATION BY REFERENCE [0001] The present application claims priority under 35 U.S.C. § 119 to Japanese patent application No. 2003-281082 filed on Jul. 28, 2003. The content of the application is incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a model apparatus in that a model train is driven along a track, and more specifically it relates to a model apparatus in that images viewed from the inside of the model train are displayed on a monitor separated from the model train. [0004] 2. Description of the Related Art [0005] A model apparatus has been known, in which a model train traveling on a railroad has an imaging camera at the head thereof for picturing images of the traveling direction so that one can see images of the traveling direction as if he or she were sitting on a driver's seat by displaying the images on a monitor installed at a position separated from the model tr...

Benefits of technology

[0019] The present invention has been made in view of such problems, and it is an object of the present invention to provide a model apparatus in that images from a model train can be continuously watched on a monitor even when the model train travels through a place surrounded by a shielding material.

[0020] In order to solve the problem described above, according to the present invention, an FM modulated image signal from an imaging camera is entered to a track composed of a conductive rail line via a contact portion, and an FM demodulation circuit connected to the track demodulates the modulated image signal so as to be fed to a monitor. Since the image signal is entered to the FM demodulation circuit connected to the track as the FM-modulated image signal, the image signal is transmitted from a model train to the monitor without being affected by noise due to a drive power supply and a drive motor connected to the track.

[0021] According to the present invention, the image signal transmission route from the model train to the monitor uses the track composed of the conductive rail line for guiding the model train and supplying drive power to the drive motor, so that components required for a radio transmission system are eliminated so as to reduce the cost of the model apparatus.

Problems solved by technology

Since only a radio signal with weak power can be used especially in a general model apparatus, this problem becomes noticeable furthermore in surroundings that electromagnetic waves exist in the vicinity.
