Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a transmitting unit and a receiving unit incorporated in a wireless device in a wireless device.

[0002]

2. Description of the Related Art In a conventional wireless device, a printed circuit board 2 on which a circuit component for transmission is mounted is disposed on the front surface of a keyboard body 1 like a keyboard shown as an example in FIG. The LED 3 for transmission is fixed by soldering.

Since the printed circuit board 2 is attached to the keyboard body 1 with the screws 4, the direction of the LEDs 3 is fixed and cannot be changed to an arbitrary direction.

In the embodiment described in Japanese Patent Application Laid-Open No. Hei 5-257585, a wireless input type information processing apparatus, a receiving section for receiving a signal transmitted from the input apparatus is provided in a main body with a display section. This receiving unit is a variable direction variable receiving unit.

However, when a conventional wireless device as shown in FIG. 6 is used, the wireless device having the receiving unit is arranged within the range of the transmittable directional angle α of the LED 3 of the transmitting unit. Need to be kept.

However, when the keyboard is moved during actual use, the keyboard 3 is deviated from the range of the directional angle α of the LED 3, and a communication error often occurs.

[0007] In order to improve this kind of problem, there is a case where a plurality of transmission LEDs 3 are installed, but the cost of the product is increased.

In the embodiment of Japanese Patent Application Laid-Open No. 5-257585, the receiving section is configured to be variable. However, in an information processing apparatus, generally, an input device is separated from a plurality of input devices such as a keyboard and a mouse. If the receiving unit is changed in accordance with the keyboard of the input device, another input device mouse or the like may be out of the reception range and a communication error often occurs.

[0009]

In a conventional wireless device as described above, when a communication error occurs because the transmission angle is exceeded, it is necessary to move an input device such as a keyboard body with respect to a receiving unit side, so that it is narrow. It is often difficult on a desk or the like.

[0010] Also, in a device in which the receiving unit can be changed, if there are a plurality of input devices, it is possible to secure an appropriate position for one input device, but conversely, the other input device will be out of an appropriate range. However, transmission and reception become unstable, and communication errors often occur.

Therefore, according to the present invention, even when a plurality of input devices such as a keyboard and a mouse are used at the same time, the input devices are not moved and the transmission units provided in the individual input devices can be freely changed. An object of the present invention is to make it possible to easily set an appropriate transmission / reception angle for each input device, to always perform optimal communication, and to prevent a communication error from occurring.

[0012]

SUMMARY OF THE INVENTION The present invention relates to a wireless device for wirelessly transmitting data from an electronic device for transmitting data, such as a keyboard and a mouse, to an electronic device for receiving data, such as a host computer. Optimized to easily change the angle of the transmission unit without moving the keyboard body by unitizing the provided transmission unit and providing the rotating unit structure and the stopper unit that stops at multiple rotation angles in the attachment part with the keyboard body Communication state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view showing an entire structure of a keyboard in which a transmitting unit according to an embodiment of the present invention is mounted, and FIG. 2 is a diagram showing a state viewed from a right side.

FIGS. 3, 4 and 5 are enlarged sectional views of the mounting structure of the transmitter unit of the present invention. FIG. 3 is a sectional view BB of FIG. 1, and FIGS. The figure is shown.

In FIG. 1, a transmitting unit 6 having an LED 3 for transmission mounted on the front surface of a keyboard body 1 is structured so that the transmitting unit 6 can be rotated in the left and right directions of the arrow without moving the keyboard body 1. Therefore, as shown in FIG. 3 showing the cross section BB of FIG. 1, the transmitting unit 6 has a built-in printed circuit board 7 on which the transmitting LED 3 is mounted. A circular flange portion 8 serving as a rotation axis is formed at 17.

A flange 11 is formed on the upper case 9 and the lower case 10 of the keyboard body 1 so as to surround the periphery of the flange 8 with an appropriate gap.

Next, when assembling the upper case 9 and the lower case 10, the assembling is performed in a state where the flange 8 provided on the transmitting unit 6 is inserted inside the flange 11 provided on the upper case 9 and the lower case 10. As a result, the transmitting unit 6 is connected to the keyboard body 1 by the flanges 11 of the upper case 9 and the lower case 10 of the keyboard body 1.
It is securely fixed in a rotatable state.

In this state, when a force is applied to the transmitting unit 6 in the direction of the arrow shown in FIG. 1, the transmitting unit 6 is moved to the keyboard body 1 with the flange 8 provided on the transmitting unit 6 as a rotation axis. Can be freely rotated in any direction.

In this manner, the position of the keyboard is moved to a place where the operator can easily operate, and the LED of the unit 6 is moved.
3 can be easily adjusted to an appropriate transmission state by rotating the transmission unit 6 without moving the keyboard body 1 even when a communication error occurs beyond the range of the transmission angle α.

Further, as shown in FIGS. 3 and 4, a plurality of holes 1 are formed in the case side surface 12 of the upper case 16 of the transmitter unit 6 to fix the transmitter unit 6 at a specific rotation position.
3 is provided on the upper case 9 of the keyboard main body 1 at a position corresponding to the hole 13 so as to provide an elastic rib 15 having a projection 14 formed thereon. As shown in FIG. The transmission unit 6 can be locked to the keyboard main body 1 by rotating into the hole 13 provided on the side surface 12 of the case, and the transmission can be performed even during operation or when an external impact is applied to the keyboard main body 1. The unit 6 can be prevented from rotating easily.

FIG. 5 is a view showing a state in which the projection 14 provided on the rib 15 of the upper case 9 does not enter the hole 13.
The protrusion 14 contacts the case side surface 12 of the transmission unit 6, and the rib 15 is elastically bent in the direction of arrow A.

The transmitting unit 6 can be rotated to a position having the hole 13 and can be arbitrarily rotated and fixed as shown in FIG.

[0023]

As described above, even if the keyboard or the like of the wireless device adopting the present invention is displaced from the wireless receiving device, the keyboard or the like is moved to the position where the communication error is eliminated like the conventional wireless device. It is not necessary to move, and the transmitting unit can be rotated to an optimum position without moving the keyboard.

[0024] Thus, the keyboard and the like can be arranged at an optimum position where work is easy, and there is an effect that a communication error can be prevented from occurring.
