[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio control device for remotely controlling a controlled object, and more particularly to a receiver of the radio control device in which various internal switches can be easily adjusted.

[0002]

2. Description of the Related Art Conventionally, a receiver of a radio control device is provided with various switches for adjusting reception sensitivity. Also, in the past, several frequency bands (27 Mz,
The frequency of the carrier wave is assigned to (40 Mz, etc.), and when changing the frequency in each frequency band, the crystal oscillators of the transmitter and the receiver were exchanged according to the frequency.

In the conventional receiver of the radio control device, the case can be divided into upper and lower parts.
It is formed of a case body and a bottom member. A circuit board on which a receiving circuit and the like are arranged is arranged in the case body, and then the case body and the bottom member are integrally formed by screws or the like. Further, an opening is formed in the case, and the crystal oscillator is detachably attached to the circuit board.

In addition, as a frequency selection method for changing to a crystal oscillator, a frequency synthesizer method has been studied in a radio control device. For example, by rotating a rotary dip switch, a frequency stored in advance in a memory is called. To choose.

[0005]

By the way, in the conventional radio control device, when the switch in the receiver is to be switched, it is necessary to remove the bottom member of the case to switch the switch, and the switching work is complicated. . In particular, there is a problem that when the operator switches the frequency selection switch as needed, not only the work becomes complicated, but also the switched state cannot be determined.

Further, it is possible to provide an opening in the case of the receiver so that these internal switches can be switched, but there is a problem that it is impossible to prevent the intrusion of dust and the like.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a receiver of a radio control device in which adjustment of internal switches is easy. In order to achieve this purpose, the structure of the present invention is
In a receiver of a radio control device that is mounted on a controlled vehicle, receives a radio wave transmitted from a transmitter, outputs a control signal, and remotely controls the controlled vehicle based on the control signal, in the case of the receiver. Has an opening formed at a position corresponding to an internal switch provided inside the case, has a translucent cover that opens and closes the opening, and projects into either the opening of the case or the cover. The guide groove is formed on the other side so as to engage with the protrusion, and the cover is provided with a stopper and a protrusion for restricting the slide position of the cover.

[0008]

[0009]

As described above, since the cover is translucent, the inside can be observed through the cover. Further, by sliding the cover or the like, the internal switch can be switched from the opening of the case.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings.
Each of the drawings shows an embodiment of the receiver of the radio control device of the present invention, FIG. 1 is a plan view of the receiver, and FIG. 2 is a right side view thereof. 3 is a plan view showing a state in which the cover is opened, and FIG. 4 is a sectional view taken along the line I-I in FIG. Furthermore, FIG. 5 (a), (b)
[Fig. 3] is a side view and a bottom view of the cover.

In the figure, A is a receiver, which has a substantially box-shaped case 1 in which electronic components constituting a receiving circuit are arranged. The case 1 is composed of a lid member 2 and a case body 3 which are made of resin. One end of the case 1 is engaged with a locking piece by an opening recess and the other end is fixed with a screw or the like to be integrated. Is configured.

Further, the cover member 2 has an opening 2a at a position corresponding to an internal switch described later. A transparent or colored semi-transparent cover 4 made of resin is slidably disposed in the opening 2a. Further, as shown in FIG. 2, a terminal portion 8 is provided on the side surface of the receiver A, and the terminal portion 8 is connected to a power supply battery or a servo device for moving a movable portion of the controlled body.

On the other hand, inside the receiver A, circuit boards 5a and 5b are provided in upper and lower two stages, and various electronic parts are arranged on the circuit boards 5a and 5b. Among them, the circuit board 5
A pair of rotary-type DIP switches 6 are provided as internal switches on a. Then, the DIP switches 6 and 6 are operated to switch the reception frequency of the receiver.

Shield plates 7a and 7b are provided on the circuit boards 5a and 5b so as to surround electronic parts,
This is a configuration that shields noise and the like from the outside. Further, in FIG. 1 and FIG. 3, 9 is a receiving antenna.

Next, the slide mechanism of the cover 4 will be described. As shown in FIGS. 5A and 5B, the cover 4 has a substantially trapezoidal cross section in the short side direction and a rectangular shape as a whole.
A guide groove 4a is formed on each side surface in the short side direction, and the guide groove 4a is open to one slope in the long side direction.
A stopper 4b and a protrusion 4c are provided on the bottom surface of the cover.

On the other hand, the opening 2a of the lid member 2 is formed with projections 2b, 2b extending in the sliding direction of the cover 4. Then, the cover 4 is elastically deformed, and the projection 2
The cover 4 can be slid with respect to the lid member 2 by engaging the guide grooves 4a and 4a with the guide grooves 4a and 4a and mounting them.

After the cover 4 is mounted, when the cover 4 is opened, the stopper 4b acts to prevent the cover 4 from coming off. Further, when the cover 4 is closed, the projection 4c contacts the case 2 and the cover 4 is fixed. However, protrusion 4
Since the height of c is low, it can be easily opened by applying an external force.

With the above-described structure, the DIP switches 6 inside the receiver A can be operated by opening the cover 4, and the reception frequency of the receiver A can be easily changed. After the frequency is changed, the cover 4 can be closed to prevent intrusion of dust or the like from the outside.

Further, the cover 4 is transparent or colored translucent made of resin, and the inside can be seen through the cover 4, so that the setting states of the DIP switches 6 and 6 can be seen, and the present reception You can check which frequency is set as the reception frequency of the machine.

[0020]

[0021]

As described above, in the receiver of the radio control device of the present invention, the setting of the internal switch can be switched by sliding and opening the cover, and the setting work can be performed very easily. Further, since the cover has a translucent structure, the setting state of the internal switch can be confirmed with the cover attached. Further, when the cover is opened, the stopper provided on the cover acts as a stopper to prevent the cover from coming off. Further, when the cover is closed, the projection provided on the cover comes into contact with the case, the cover is fixed, and the cover is not easily opened in the closed state.
