It is designed for easy cleaning.

According to a second aspect of the invention, in the first aspect of the invention, there is a case where the user forgets to cancel the state in which all the key operations are invalidated and may be mistaken for a failure. All key operations are enabled, the function is automatically released after a few minutes, and it is prevented that the key is operated in the disabled state for a long time.

According to a third aspect of the present invention, in the first or second aspect of the invention, there is a case where it is not noticed that all the key operations are invalidated. At this time, a display unit for displaying that the specific key is pressed is provided, and it is possible to know that the operation preventing function is operating by seeing the lighting of the display unit LED or the like. .

According to a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, when all the keys are in an invalid state and an incoming call is received, the key is pressed to release the key. In view of the fact that there is a case where it is not possible to operate correctly, if there is an incoming call while the specific key is pressed, the function of the specific key is canceled, and if there is an incoming call, it will be as usual. It can be operated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing a main part configuration for explaining an embodiment of a telephone device according to the present invention. In the figure, 1 is a control unit for controlling the operation of the entire telephone, and 2 is a control unit. Is a specific key "P", and when this key 2 is pressed, the operation of all keys is invalidated or enabled, and the display unit (LED) 4 lights up when all the keys are invalidated. , Is off when enabled. Reference numeral 3 is a key operation unit such as a numeric keypad or abbreviated key, and 8 is an incoming call detection unit for detecting whether an incoming call arrives.
It is connected to the handset 5 through the call circuit 6.

(Invention of Claim 1) FIG. 2 is a flow chart for explaining the invention of Claim 1. When the specific key "P" is pressed (S1), the LED 4 lights up (S2),
All key operations are invalidated (S3). In this state, the telephone is cleaned (S4), and after the cleaning is finished, when the above-mentioned specific key "P" is pressed again (S5), the LED 4 is extinguished (S6) and all key operations are enabled (S7). ), And returns to the normal state (S8). In this way, by pressing the specific key “P”, all key operations of the key operation unit 3 can be invalidated / validated.

(Invention of Claim 2) FIG. 3 is a flow chart for explaining the invention of Claim 2, and if a specific key "P" is not pressed in S5 of the flow chart of FIG. The operation is invalid (S11),
The LED 4 is on (S12). When the specific key "P" is pressed in this state (S13), the process returns to the flowchart of FIG. 1, the LED goes out, and the normal state is restored. However, in S13, if the specific key is forgotten, When the specific time has elapsed (S14), the LED is turned off (S15), all key operations are enabled (S16), and the normal state is restored. According to the invention of claim 2, it has a function of automatically releasing the operation of the specific key pressed in the invention of claim 1 after a fixed time, and the function is controlled in the controller 1 for a fixed time. Then, even if the specific key "P" is not pressed, the operation of claim 1 is automatically canceled and the normal state is restored.

(Invention of Claim 3) In the invention of Claim 3, in the invention of Claim 1, when a specific key "P" is pressed,
The specific key "P" is pressed to display that all key operations are disabled. When the specific key "P" is pressed in the flow chart shown in FIG. In (S1), the LED is turned on (S2), and it is displayed that all key operations are invalid.

(Invention of Claim 4) FIG. 4 is a flow chart for explaining the invention of Claim 4, in which all keys are in an invalid state (S21) by pressing a specific key "P". , When the LED is lit (S22) and there is an incoming call (S23), the incoming call detection unit 8 catches the incoming call and picks up the handset (S24), the LED goes off (S25), as in a normal telephone. ), All key operations are enabled (S2
6) The normal state is set (S27). Alternatively, in S24, when the specific key "P" is pressed (S31), the LED is extinguished (S32), and all the key operations are enabled, as in the case of the invention of claim 1, without picking up the handset. S3
3) The normal state is set (S34), that is, by operating the specific key "P", the operation of the specific key is returned to the valid state, and the handset is picked up in this state (S35),
Make a call.

[0013]

According to the first aspect of the present invention, a plurality of operation keys are provided, and by pressing a specific one of them, all key operations are disabled, so that the button function of the telephone is suspended. It is possible to freely stop the telephone when desired, for example, by pressing this specific key at the time of cleaning, the telephone can be easily cleaned without causing a malfunction of the telephone.

According to the invention of claim 2, in the invention of claim 1, there is a case where the user forgets to cancel the state in which all the key operations are invalidated and may be mistaken for a failure. Since all the key operations are enabled and the functions are automatically released after a few minutes, it is possible to prevent the key operations from being disabled for a long time.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the specific key is pressed in view of the fact that it may not be realized that all the key operations are disabled. At this time, since the display unit for displaying that the specific key is pressed is provided, it can be seen that the function is operating by looking at the display unit such as lighting of the LED or the like.
