Description

[Detailed Description of the Invention] (Description of the Prior Art) Conventionally, optical pointer members have been used in button attachment devices to indicate the attachment position of a button to fabric. Such optical pointer members generally consist of a tubular member containing a light source and an optical path for guiding light from the light source, and a light guide for guiding light from the optical path is provided below the tip of the tubular member. A lead-out hole is provided.

And as a part for energizing the light source,
Conventionally, electric wire parts such as vinyl-coated electric wires have been used, and these electric wires have been used to connect power terminals provided on the button mounting device body side and the optical pointer member, respectively, or to connect the power terminals provided on the optical pointer member. It is drawn directly into the light source through the lead-in hole.

However, since the optical pointer member of such electric wire parts is configured to repeatedly move back and forth with respect to the upper mounting die as described above, it is repeatedly bent and stretched, and the vinyl sheath and electric wire The fatigue of the core member is accelerated. Furthermore, because these wire components are located near complex machinery, there is a high possibility that workers may inadvertently come into contact with them, which can cause excessive force to be applied to the wire components and cause them to easily break. Ru.

(Purpose of the invention) The purpose of the invention is to eliminate electric wire parts disposed between the respective devices in a mounting position display device for use in a button mounting device.

Another object of the present invention is to provide a contact member for selectively electrically connecting and disconnecting the button mounting device and the mounting position display device.

(Summary of the invention) According to the invention, in a mounting position display device for use in a button mounting device, a contact member is provided on each of the fixing member and the optical pointer member that constitute the mounting position display device. The contact members are positioned such that they contact each other when the optical pointer member is advanced relative to the plunger in response to the upward movement of the upper mounting die of the button mounting member.

DESCRIPTION OF THE PREFERRED EMBODIMENT Please refer to FIG. The mounting position display device 3
is fixed by a fixing member 4 to a button attachment device 5, a portion of which is shown by broken lines in FIG. An optical pointer member 6 having a built-in light source (not shown) is provided in a part of the fixing member 4, and a light guide hole 7 provided at the tip thereof is located directly below the upper mounting die.
That is, a support member 9 for supporting the plunger so as to be movable back and forth with respect to a position of intersection with the plunger centerline 8 is integrally coupled.

The optical pointer member is pushed toward the plunger centerline 8 as shown in FIG. 3 by abutting a part of the rear end surface 10 with a member 11 that works in conjunction with a pusher (not shown) of the button attachment device. Then, the structure is such that it returns to its original position, ie, the position shown in FIG. 2, by the repulsive force of the spring member 12 interposed in the intermediate portion.

An electrical contact member 1 made of a conductive material is disposed on a part of the fixed member, and an electrical contact member 2 made of a similar material is disposed on a part of the optical pointer member. A fixed electric wire member (not shown) is connected to the electric contact member 1, for example, and is incorporated into the main body of the button attachment device and connected to a power source, thereby supplying electric power to the electric contact member 1. On the other hand, the electrical contact member 2 provided on the optical pointer member side is inserted into the optical pointer member and connected to the light source. These electrical contact members 1 and 2 are such that the optical pointer member 6 is pushed toward the right side of the figure by the member 11 as shown in FIG. When aligned with the intersection of the two members, they are positioned so as to come into contact with each other, and due to the contact between these members, electric power is conducted from the electrical contact member 1 to the electrical contact member 2, and the light source is turned on.

Although the present invention has been described above based on embodiments, it should be noted that many changes may be made within the present invention.
