1). When the main control unit 701 determines in ST101 that the predetermined time has elapsed, the main control unit 701 scans the state of the input from the key top 103 (hereinafter, referred to as key input), that is, determines whether or not there is an input. 10
A key input state is input to the key input register 1000 shown in (a) (ST102).

The key input register 1000 includes a scroll input bit 1001 for storing the input state of the scroll switch 129 and a scroll switch 1
Scroll input bit 100 storing 30 input states
2. It has a telephone directory input bit 1003 for storing the input state of the telephone directory switch 132, and a menu input bit 1004 for storing the input state of the menu switch 133. If there is an input from each of the switches 129, 130, 132, and 133, 1 is input to each of the bits 1001 to 1004, and if there is no input, 0 is input. The key input register 1000 may use the internal register of the main control unit 701 or the RAM unit 703.

Next, main controller 701 determines whether or not the process of ST102 has been performed four times (ST103). If the main control unit 701 determines in ST103 that the process of ST102 has not been performed four times, the process proceeds to ST101.
Returning to the processing of step S, until the processing of ST102 is performed four times,
The loop from T101 to ST103 is repeated. On the other hand, ST
In 103, the main control unit 701 executes the process of ST102 in 4
When the main control unit 701 determines that the key input register 1 has been executed four times,
000 is the same for all four times (S
T104). The main control unit 701 performs ST102 to ST104.
This is because it is necessary to determine whether the key input is caused by noise such as vibration or impact.

In ST104, when main control section 701 refers to key input register 1000 and determines that the four key input data are not the same, it can be determined that the key input is caused by noise. Return.

On the other hand, in ST104, main control unit 70
When the key 1 refers to the key input register 1000 and determines that the four key input data are the same, it can be determined that the key input is not caused by noise. Therefore, whether the input state determined by the main control unit 701 is a state in which a key input is performed or a state in which no key input is performed, that is, whether one of the bits 1001 to 1004 of the key input register 1000 is 1, It is determined whether all bits 1001 to 1004 are 0 (ST105). FIG. 10 (b)
A state where all the bits 1001 to 1004 are 0, that is, the key input register 100 in a state where no key input is performed.
FIG.

If the main control unit 701 determines in ST105 that there is no key input, the main control unit 7
Since 01 does not need to perform any processing, the process returns to ST101.

On the other hand, in ST105, main control unit 70
If it is determined that there is any key input, the main control unit 701 refers to the key input register 1000 and determines whether the key input is an input by pressing the scroll switches 129 and 130 (ST106).

If the main controller 701 determines in ST106 that the key input is an input by pressing the scroll switches 129 and 130, scroll processing is performed (ST1).
07). FIG. 10C shows a scroll switch 129,
FIG. 10 is a diagram showing the key input register 1000 in a state where a key input has been made from one of the key input registers 130; Further, FIG.
0 (c) is also a diagram showing the key input register 1000 in a state where two switches are pressed at the same time.

As described above, the key top 103
Is a switch facing the scroll switch 12
9, 130 or the telephone directory switch 132 and the menu switch 133 are not pressed simultaneously. Therefore, 1 is not input to the scroll input bits 1001 and 1002 at the same time. Also, 1 is not input to the telephone number input bit 1003 and the menu input bit 1004 at the same time.

On the other hand, in ST106, main control unit 70
If it is determined that there is no key input from the scroll switches 129 and 130, the telephone book search processing or various setting processing is performed (ST108). FIG. 10 (d)
FIG. 10 is a diagram showing the key input register 1000 in a state where no key input is made from the scroll switches 129 and 130.

That is, when the main control unit 701 determines in ST106 that there is an input by pressing the scroll switches 129 and 130, the main control unit 701 performs scroll processing even if other inputs are made at the same time. become. In other words, the main control unit 701 enables only the input from the scroll switches 129 and 130 and disables the input from the other switches.

As described above, according to the above embodiment, even when a plurality of switches are pressed at the same time unexpectedly, only the input from the scroll switches 129 and 130 is made effective, and the other switches 132 and 133 are turned on. Disable input of. Thus, even when a plurality of switches are pressed at the same time unexpectedly, the operation is performed without causing any inconvenience.

Further, in the above-described embodiment, the projection 131 is provided at a position facing substantially the center of the key top 103 of the switch sheet 104. Thereby, when the operator presses the key top 103, the four switches 12
9, 130, 132 and 133 are not pressed at the same time. In other words, no more than two adjacent switches are pressed simultaneously. Thereby, the possibility that a plurality of switches are pressed simultaneously is reduced to some extent. In addition, this limits the combinations of switches that are pressed at the same time, and only the input from one of the two switches needs to be selected. Therefore, the possibility that the input intended by the operator becomes valid increases.

According to the above embodiment, when a plurality of switches are simultaneously pressed, only the inputs from the frequently used scroll switches 129 and 130 can be validated. This increases the possibility that the input from the switch intended by the operator is selected. As a result, the operator is prevented from feeling uncomfortable.

Further, according to the above embodiment, the display screen of the display unit 705 is automatically and continuously scrolled by continuously pressing the key top 103 as indicated by reference numerals 801 and 802 in the figure. If the switch adjacent to the key top is unexpectedly pressed in a certain direction while the user is in the position, only the input from the scroll switches 129 and 130 is made valid, so that the scroll automatically continues. As a result, the operator can continue the operation without feeling uncomfortable.

Further, according to the above embodiment, the scroll switches 129 and 130, the telephone directory switch 132 and the menu switch 133 can be operated with one key top 103. Thus, the operator can easily operate the telephone.

In the above embodiment, the key top 1
Although the description has been made with reference to the configuration in which 03 presses four switches, a configuration in which the key top depresses four or more switches may be used. Furthermore, in the above embodiment, two
Although a configuration in which only one switch is pressed is used, a configuration in which two or more switches are pressed simultaneously may be used.
In this case, the above-described effect can be obtained effectively by enabling only the input from the switch that is frequently used.

In the above embodiment, the scroll switch 12 is pressed when two switches are simultaneously pressed.
Although the description has been made in the form of validating the input from the switches 9 and 130, the input from a switch other than the scroll switches 129 and 130 may be validated in accordance with the function of the telephone and the request of the user.

As a modification of the above embodiment, the input from the previous switch is stored, and when two switches are simultaneously pressed, the input from the same switch as the input from the previous switch is enabled. It is also conceivable to take the form. Usually, a situation in which two switches are pressed at the same time is highly likely to occur when the same switch is repeatedly hit or when the same button is continuously pressed and automatically scrolled. Therefore, in this mode, the switch intended by the operator is selected. As a result, the operator can continue the operation without feeling uncomfortable.

In the above embodiment, the description has been made using a telephone. However, the present invention can be applied to any electric device that may have a plurality of buttons pressed at the same time. Further, in the above-described embodiment, the description has been made in the form in which the plurality of switches are covered with the keytop. However, even if the plurality of switches are not covered with the keytop, they may be arranged close to each other and pressed simultaneously. It can also be applied to forms that have high performance.
