BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linear motor type curtain device suitable for use as a curtain device attached to a window of an automobile or a house.

[0002]

2. Description of the Related Art Conventionally, a curtain device using a linear motor has been disclosed in Japanese Patent Application Laid-Open No. Sho 62-52303 and Japanese Patent Application Laid-Open No.
No. 7112 and JP-A-4-79916.

[0003] This kind of linear motor type curtain device is
The cross section has a substantially rectangular shape with a hollow inside, and a positive electrode pattern and a negative electrode pattern are formed on a substrate and a field portion having a magnet group in which different poles are alternately arranged on the inner surface of a rail main body having a longitudinal slit at the bottom. A curtain rail portion provided with a power supply portion (commutator) having the same, and a movable portion which is disposed inside the curtain rail portion to generate and move a magnetic pole to the field portion by power supply from the power supply portion. Constitute. Then, when a plurality of runners are movably loaded on the curtain rail portion, the curtain is hung on each runner, and one end of the curtain is hung on the movable portion, the curtain is opened and closed by the movement of the movable portion.

[0004]

The curtain rail used in the above-mentioned conventional linear motor type curtain device may be several meters or more depending on the mounting place. The unit rails are divided into a plurality of unit rails, and the unit rails are connected to each other at the time of installation and assembled to one curtain rail. In this case, the rail body portions can be relatively easily connected to each other by using a bracket or the like. However, when connecting the power supply portion, the substrate has a positive electrode pattern and a negative electrode pattern, and the positive electrode pattern and the negative electrode pattern. Since the brush that moves together with the movable portion slides, it is necessary to ensure the flatness (continuity) of the butted portion of the coupling end, and the coupling is not easy.

Therefore, conventionally, a part of the positive electrode pattern and the negative electrode pattern is projected forward of the connecting end of the substrate, and is wound on the back side along the connecting end, so that the positive electrode patterns of each substrate can be connected to each other on the back side. The negative electrode patterns were connected to each other (see Japanese Utility Model Laid-Open No. 1-162778). However, in such a conventional connection method, the structure of the coupling end portion is complicated, and a dent or the like is easily generated at a portion where the coupling end portions abut with each other. Therefore, it is difficult to ensure smooth contact with the brush. There has been a problem that defects and failures are likely to occur.

The present invention solves the problems existing in the prior art as described above, and simplifies the structure and improves the flatness of a coupling portion in a power supply portion, so that poor contact with the brush is achieved. It is an object of the present invention to provide a linear motor type curtain device which can prevent the occurrence of a failure or a failure and can enhance the reliability.

According to the present invention, a positive electrode pattern is formed on a field portion 4 and a substrate on an inner surface of a rail body 3 having a substantially rectangular cross section and a longitudinal slit at the bottom. By providing a curtain rail section 2 provided with a power supply section having a negative electrode pattern and inside the curtain rail section 2, magnetic poles 7 for the field section 4 are generated and moved by power supply from the commutator 5. ... The linear motor-type curtain device 1 includes the movable portion 6 and divides the curtain rail portion 2 into a plurality of unit rail portions 2r, 2d. In particular, the positive electrode patterns 9rp and 9dp are arranged on one side in the width direction of the substrates 8r and 8d in each of the unit rail portions 2r and 2d, and the negative electrode patterns are formed on the other side in the width direction. rn, with arranging the 9Dn, each substrate 8r, coupling end of the 8d 8RS, respectively notch 10r in the width direction on both sides in 8ds, 11r, 10d, 11
