Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a receiving apparatus such as an electronic device that includes a receiving unit that receives a signal and a button for operation.
[0002]
[Prior art]
In electronic devices such as television receivers, audio devices, personal computers, etc., various buttons for a plurality of operations are used on the surface or side of the device, but the buttons are not turned on to prevent malfunction. Some lock mechanisms have been devised. As a method for locking the operation unit, for example, there is a method described in JP-A-11-317123.
[0003]
As shown in FIG. 8, this method is a lock mechanism of the power switch 18 for preventing a person from operating the power switch 18 by mistake, and the power switch 18 is housed in a recess 20 provided in the container 12a. At the same time, an opening / closing lid 22 capable of closing the opening is provided at the opening of the recess 20.
[0004]
[Problems to be solved by the invention]
The above-described method has a problem that it is necessary to operate the power switch 18 while opening the opening / closing lid 22. Further, this method is limited to only the manual power switch 18, and a receiving apparatus having a remote control function for receiving a remote control signal to control on / off of the switch has a function to block the malfunction. Not.
[0005]
[Means for Solving the Problems]
The present invention includes an electronic device having a button for operating a button having a lock means that prevents the operation of the button so that an infant or the like does not operate the button by mischief. A characteristic receiving apparatus is provided.
[0006]
In addition, even if the remote control is operated by changing the direction of the button provided with the locking means of the receiving device so that the signal from the remote control transmitting device (hereinafter referred to as the remote control) does not reach the receiving device. It is an object of the present invention to provide a receiving device including a lock unit that can prevent a device from reacting.
[0007]
Normally, the buttons are used as parts for operating the switch, so that they can be pushed in. By rotating these buttons, a pushable state and a non-pushable state are created and a lock function is provided. For this purpose, the buttons are provided with ribs, and the cabinet is provided with recesses and through holes.
[0008]
In addition, by providing a structure that shields the signal receiving unit from the remote controller in the vicinity of the button, a state in which an operation from the remote controller is not consciously created is created.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a receiving apparatus including a lock mechanism that enables operation of an operation unit by changing the direction of a button. By having such a configuration, it is possible to prevent a malfunction from being caused by accidentally touching the button. For example, even if an infant or the like mischiefly touches the operation unit, the button cannot be operated. Has the effect of preventing erroneous operation.
[0010]
The present invention also relates to a receiving means that has a function of preventing malfunction even when controlled from a remote controller. By changing the direction of the button of the receiving device, the remote controller signal is prevented from reaching the receiving section, and intentionally. It is characterized in that the receiving device does not react even if the remote control operation is operated, and this prevents malfunction of the receiving device even if the remote control is operated by mistake, for example due to mischief such as infants It has the effect of not reacting even with remote control operation and causing no malfunction.
[0011]
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
[0012]
(Embodiment 1)
1 (a), 1 (b), and 1 (c) are cross-sectional views showing one configuration example of the button 1 of the receiving device of the present invention. FIG. 2 (a) and FIG. 2 (b) ) Is a cross-sectional view showing a configuration of a part of the cabinet 5 of the receiving device to which the button 1 is engaged, and FIGS. 3 and 4 are cross-sectional views showing a configuration of engaging the button 1 and the cabinet 5 of the receiving device. 3 is a cross-sectional view showing a state before engagement, and FIG. 4 is a cross-sectional view showing the state of engagement. FIG. 5 is a state where the button 1 is engaged with the cabinet 5, and the button 1 is in a locked state. FIG. 6 is a perspective view showing a state in which the button 1 is unlocked, that is, a state in which the button 1 can be operated.
[0013]
1 to 5, 1 is a button, 2 is a rib, 3 is a claw, 4 is a shaft, 5 is a cabinet, 6 is a recess, 7 is a through hole, 8 is a hole, 9 is a coil spring, and 10 is a power switch.
[0014]
The button 1 is provided with two ribs 2 at symmetrical positions, and includes a claw 3 for preventing disengagement and a shaft 4 for receiving a switch when the switch is pushed. The cabinet 5 has a hole 8 through which the shaft 4 passes and the claw 3 is fitted. Around the hole 8, two through holes 7 are formed at symmetrical positions so as to avoid the recesses 6 and ribs 2 to which the rib 2 is applied.
[0015]
As shown in FIG. 3, a coil spring 9 is sandwiched between the cabinet 5 and the button 1, and a force for constantly returning the button 1 is generated. The claw 3 is hooked on the cabinet 5 so that the button 1 cannot be removed. FIG. 4 shows the assembled state. When the rib 2 is at the concave portion 6 as shown in FIG. 5, even if the button 1 is pushed, the rib 2 hits the concave portion 6 and cannot be pushed any further. As a result, an inoperable state can be created.
[0016]
Further, the rib 2 is caught in the recess 6 and it is possible to prevent the rotational direction from being displaced. When it is desired to make the button 1 operable, the button 1 is rotated by 90 ° as shown in FIG. 6 and the rib 2 is positioned at the position of the through hole 7. The through-hole 7 is not a contact with the rib 2, the button 1 can be pushed in, and the power switch 10 can be operated.
[0017]
From the above, the operation unit can be easily locked by rotating the button 1 by 90 °, and the infant cannot operate the operation unit.
[0018]
(Embodiment 2)
Next, a second embodiment of the receiving apparatus of the present invention will be described with reference to the drawings. In addition, about what was demonstrated in (Embodiment 1) about the code | symbol, it has an equivalent function and detailed description is abbreviate | omitted in description of this Embodiment.
[0019]
FIG. 7 is a cross-sectional view showing a configuration in which the button 1 of the receiving device is engaged with the cabinet 5, but the button 1 includes a shielding plate 11, and the shielding plate 11 covers the remote control receiver 12 provided in the cabinet. FIG.
[0020]
A shielding plate 11 larger than the remote control receiving unit 12 is provided on the button 1. The shielding plate 11 is configured to hide the remote control receiver 12 when the button 1 is in the locked state.
The remote control signal from the remote control transmitter does not reach the remote control light receiving unit 12 hidden by the shielding plate 11, thereby making it possible to intentionally limit the remote control operation.
[0021]
As for the button locking mechanism, the concave plate 6 and the through hole 7 of the cabinet 5 are arranged so that the shielding plate 11 hides the remote control receiving unit 12, or the position of the rib of the button 1 is devised to contact the button 1. It is possible to prevent the operation of the receiving apparatus from both the malfunction caused by the above and the malfunction from the signal from the remote control transmitter.
[0022]
From the above, providing the shielding plate 11 on the button 1 has an effect of preventing operation of the device by remote control operation while having a button locking mechanism.
[0023]
【The invention's effect】
As described above, according to the present invention, the receiving device having the operation unit has an effect that an infant or the like does not mischievously operate the operation unit. Further, by changing the direction of the remote control device, the receiver of the remote control light receiving unit is covered and the device does not react even when the remote control operation is operated.
[0024]
Further, by forming the shielding plate 11 on the button 1 of the receiving device, two effects can be obtained with the same component.
