[0072]

As described above, according to the first aspect of the present invention, when a plurality of switch members arranged side by side are operated alone, a command signal is individually output, and at least one of the plurality of switch members is output. In a switch device in which different command signals are output when the two members are simultaneously operated, the erroneous operation prevention means is provided so as to straddle the at least two switch members. Can be prevented. This allows
With a small number of switch members and a simple circuit configuration, many functions can be reliably exhibited while preventing occurrence of erroneous operations.

According to the second aspect of the present invention,
The erroneous operation prevention means divides the operation surfaces of the two switch members arranged adjacently into two in the adjacent direction and includes two partition members extending in the width direction of the operation surface. The two switch members can be reliably operated simultaneously by placing a finger on the inside, and the two switch members can be reliably operated alone by placing a finger on the outside of the two partition members.

According to the third aspect of the present invention,
Since the interval between the two partition members is set so that only one finger can enter, one finger is inserted between the two partition members to press the operation surfaces of the two switch members, thereby enabling reliable simultaneous operation. be able to.

According to the fourth aspect of the present invention,
Since the two partition members protrude higher than the operation surface of the switch member, the finger can be correctly positioned between the two partition members.

According to the fifth aspect of the present invention,
Since the operation surfaces of the two switch members located between the two partition members are depressed, the finger can be correctly positioned in the depressions.

According to the invention described in claim 6,
Since the two partition members cannot be displaced in the pressing direction of the operation surface of the switch member, only the two switch members can be simultaneously operated with a finger placed between the two partition members.

According to the invention described in claim 7,
Since the two partition members are integrally formed on the operation surface of the switch member, the two switch members can be simultaneously operated with the partition member by a finger placed between the two partition members.

According to the invention described in claim 8,
Since the cover member that covers the operation surface of the switch member located between the two partition members protrudes higher than the operation surface at the other position, it is possible to press the cover member and reliably operate the two switch members simultaneously. it can.

According to the ninth aspect of the present invention,
When a plurality of juxtaposed switch members are independently operated, a command signal is individually output, and when at least two of the plurality of switch members are simultaneously operated, a different command signal is output. When the operation is performed, an auxiliary operation surface different from the operation surfaces of at least two switch members is pressed to perform the simultaneous operation. Therefore, it is possible to prevent an erroneous operation between the single operation and the simultaneous operation of the switch members. Thus, with a small number of switch members and a simple circuit configuration, many functions can be reliably exhibited while preventing occurrence of erroneous operation.
