Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an alarm unit attached to an electronic device such as a portable alarm device or a mobile phone or a wireless call receiver, and in particular, prevents the alarm unit from malfunctioning and recognizes that it is in a malfunction prevention mode. The present invention relates to an electronic device with a possible alarm sound generation function.
[0002]
[Prior art]
As an operation method of the alarm unit of the electronic device with an alarm sound generating function, a plug type switch as described in JP-A-58-54496 or a push type described in Japanese Utility Model Laid-Open No. 4-38148 is used. Some electronic devices that use switches and have only an alarm function, portable radio devices with an alarm function, and the like are currently on the market.
[0003]
The alarm is generally used to ensure its own safety when encountering a thief, etc. The operation of the alarm generates a high frequency sound such as a horn or buzzer, and a loud sound. It surprises and repels molesters, informs the people around you about their dangers, and calls for help. For this reason, when the alarm function is activated due to a malfunction in a crowded train or the like, the passengers around him are inconvenienced and uncomfortable.
[0004]
As a method of preventing malfunction, in the case of a plug type switch alarm device, in a crowded place such as in a crowded train, usually put it in a bag etc. and take it out from a bag etc. in a place with few people, and plug type A string attached to the switch is attached to a bag or the like to prevent malfunction in handling such as pulling the alarm device in an emergency and pulling out the plug type switch. As for the push-type switch, as described in Utility Model Registration No. 3033707, the push-type switch is prevented from protruding from the surface of the housing to prevent malfunction.
[0005]
Further, as a method related to a radio device, as a method of preventing malfunction of a push-type switch, there is a method using a slide cover for protecting the switch as described in JP-A-64-89844, or an invalid switch for preventing malfunction. The switch operation input after that is invalidated by the input of the switch.
[0006]
Further, as a method for allowing the user to recognize that the operation mode is the malfunction prevention mode, as described in JP-A-9-64803, when there is a switch input in the malfunction prevention mode, the LED is turned on each time the switch is input. There are things to let you know.
[0007]
[Problems to be solved by the invention]
However, in the action to prevent malfunction of the plug type switch as described above, it is forced to be stored in a bag etc. in order to prevent malfunction even in a crowded place where it is easy to encounter a molester such as a crowded train. Even when it was necessary, it took time to take it out of the bowl and deal with it. Further, since it is used quickly in a crowded train or the like, it may cause an alarm function to be erroneously activated when an electronic device such as an alarm device is previously held by hand.
[0008]
Electronic devices that have only an alarm function are not frequently used, but can be stored in a bag etc. and taken out and used when necessary. However, in the case of an electronic device equipped with a warning function in a mobile phone, a radio call receiver, etc., it is used more frequently than an electronic device having only a warning function and should be stored in a bag as needed. This is not preferable because it restricts the original function of the product.
[0009]
As described in the prior art, the method for preventing the malfunction of the push type switch can be solved by providing the switch with a cover or providing a switch for invalidating the switch input. However, if a user is attacked by a thief in the dark, such as at night, with a cover that protects the switch or a switch that disables the switch input to prevent malfunction, the user usually falls into confusion and malfunctions. There is a case where the alarm function cannot be activated quickly without noticing that it is in the prevention mode.
[0010]
In addition, in order to solve the above-mentioned problem, as in the prior art, in the malfunction prevention mode, when another switch is input, the LED is turned on each time, and in a device that can recognize the malfunction prevention mode, the switch is at least once. If it is impossible to recognize that it is a malfunction mode unless it is input, and it is necessary to quickly activate the alarm function, it takes time to perform a useless act.
[0011]
The present invention has been made in order to solve the above-described conventional problems. The malfunction of the alarm function by the plug-type switch is prevented, and the fact that the malfunction prevention function is working is visually displayed. It aims at improving.
