2. Description of the Related Art FIG. 8 shows a conventional optical transmission electronic device, such as a digital audio device having an optical connector for digital audio devices (hereinafter referred to as an optical connector) specified in EIAJ RCZ-6901, installed in a car. It is a perspective view showing an example. In Figure 8, 1
is the panel surface of the device, 2 is the optical connector (female type) attached to the panel surface 1 of the device, 4 is the optical connector (male type) made so that it can be inserted and removed from the optical connector 2, and 5 is the optical connector 4 is an optical cable attached to its tip, 7 is an external digital audio device with an optical connector, and 8 is an automobile shift lever.

FIG. 9 is a cross-sectional view showing the optical connector mounting portion of the digital audio equipment. Figure 9
, 1, 2, 4, and 5 indicate the same parts as the conventional device described above, and 3 is a light receiving or light emitting element that is optically coupled to the optical cable 5 when the optical connector 4 is inserted into the optical connector 2. .

Furthermore, FIG. 10 is a perspective view showing an example of a conventional digital audio device used indoors. In FIG. 10, 1, 2, 4 and 5 indicate the same parts as the conventional device described above.

[0005] An optical connector in a conventional digital audio device is constructed as shown in FIG. Therefore, in order to insert the optical connector 4 into the optical connector 2 and optically couple the optical cable 5 with the light receiving or light emitting element 3, the direction in which the optical cable 5 is taken out is perpendicular to the panel surface 1.

Furthermore, when a conventional digital audio device is mounted in a car, the optical cable 5 is pulled out in a direction perpendicular to the panel surface 1 of the device, as shown in FIG. Since the optical cable 5 is usually made of plastic resin or glass fiber, the cable itself is hard and not highly flexible, so it hangs down protruding from the panel surface 1 of the device. Furthermore, as shown in FIG. 8, when driving a car, the shift lever 8 of the car and the optical cable 5 protruding from the panel surface 1 of the device are in a positional relationship in which they easily come into contact with each other or come very close to each other.

In addition, even when conventional digital audio equipment is used indoors, the optical cable 5 is pulled out in a direction perpendicular to the panel surface 1 of the equipment, as shown in FIG. In this case as well, since the optical cable 5 does not have good bendability, it protrudes from the panel surface 1 of the device.

[0008]

[Problems to be Solved by the Invention] In the conventional optical connector for digital audio equipment as shown in FIG. Since the optical cable 5 is structured so that the direction in which the optical cable 5 is taken out is perpendicular to the panel surface 1 when the device is connected to the There was a problem that the optical cable could get in the way of panel operation, or could get caught on people or objects, causing damage to the optical cable.

The invention of claim 1 has been made to solve the above-mentioned problem, and when optical cables are optically coupled to optical connectors, the optical cables may become a hindrance to panel operation or may come into contact with human bodies or objects. An object of the present invention is to obtain an optical transmission electronic device that can reduce the risk of damage to an optical cable due to getting caught.

[0010] Furthermore, the invention of claim 2 provides an optical transmission electronic device that can be moved in a direction that facilitates insertion and removal when an optical cable is inserted and removed, and that can be moved in a direction that prevents the optical cable from getting caught and damaged when connecting the optical cable. The purpose is to obtain.

[Means for Solving the Problems] The optical transmission electronic device according to the invention of claim 1 is characterized in that the direction in which the optical cable is taken out when optically coupling the optical connector and the optical cable is not perpendicular to the panel surface of the electronic device. It is equipped with a connector for the electronic equipment attached to the

Further, in the optical transmission electronic device according to the invention of claim 2, a movable mechanism is provided in the optical connector on the electronic device side so that the optical cable is taken out in a direction perpendicular or not perpendicular to the panel surface of the device. It is something that

[0013]

[Operation] In the invention as claimed in claim 1, when the optical cable is optically coupled to the optical connector on the side of the optical transmission electronic device, the direction in which the optical cable is taken out is in a direction in which the optical connector on the side of the electronic device is not perpendicular to the panel surface. This reduces the amount of protrusion of the optical cable, reducing the risk of the optical cable getting in the way or getting caught on a human body or object, thereby reducing the risk of damage to the optical cable.

Further, in the invention of claim 2, by providing a movable mechanism in the optical connector on the side of the electronic device, when the optical connector to which the optical cable is connected is inserted into and removed from the optical connector on the side of the electronic device, the optical connector on the side of the optical device is moved. Once the optical connector on the cable side has been connected to the optical connector on the electronic equipment side, move the optical connector on the electronic equipment side to change the direction in which the optical cable is taken out. The amount of optical cables protruding from equipment panels is reduced, reducing the risk of optical cables getting in the way of panel operation or being damaged by getting caught on people or objects.

In FIG. 5, numerals 1, 2, 4, and 5 indicate the same parts as those of the conventional device described above. Further, it is shown that the direction in which the optical cable 5 is taken out is diagonally upward or diagonally downward, respectively, with respect to the panel surface 1 of the device.

In the optical connector in the digital audio equipment configured as described above, the insertion direction of the optical connector 4 is not perpendicular to the panel surface 1 of the equipment, so the optical cable 5 is inserted from the panel surface 1 of the equipment.

It is possible to reduce the risk of

Further, according to the second aspect of the invention, since the optical connector is provided with a movable mechanism, it is possible to move the insertion/extraction direction vertically or in a direction other than vertically.
