The disclosed embodiments relate to operating devices.

Conventionally, an operating device for remotely controlling a water-related device such as a toilet device, a toilet seat device, or a faucet device may be provided in a water-related space such as a toilet room, a washroom, or a kitchen (see, for example, Patent Document 1). ).

In such an operation device, the function corresponding to this operation unit is described near the operation unit to be operated when the user realizes a predetermined function, and Braille is formed, so that the user is visually impaired. It is known that a person can also recognize the function of the operation unit (see, for example, Patent Document 2).

Japanese Unexamined Patent Publication No. 2006-9505 Japanese Unexamined Patent Publication No. 2003-147834

By the way, even in an operation device provided with a capacitance type operation unit that accepts an operation based on the capacitance between the human body (user's finger) and the electrostatic element (electrode), Braille is formed in the vicinity of the operation unit. Is preferable.

However, when a capacitive operation unit is provided, the finger may approach the operation unit during Braille reading by a visually impaired user, and the operation unit may accept the operation unit. It is necessary to suppress unintended operations by the person.

One aspect of the embodiment is made in view of the above, and an object of the present invention is to provide an operating device capable of suppressing an unintended operation during Braille reading by a user.

In the operation device according to one aspect of the embodiment, a capacitance type operation unit that accepts an operation when the user realizes a predetermined function and a function corresponding to the operation unit in the vicinity of the operation unit are described. A Braille member having a display unit and a reading surface located on the display unit and having Braille corresponding to the display unit formed, and having a space between the display unit and the operation unit is provided.

According to such a configuration, since the Braille member has a space between the Braille member and the operating portion, the parasitic capacitance increases and it becomes difficult for the current to flow from the reading surface to the operating portion. Therefore, even if the user's fingers approach the operation unit during the user's Braille reading, the energization of the electrostatic element can be suppressed. As a result, it is possible to suppress an unintended operation (erroneous operation) during Braille reading by a visually impaired user.

Further, the operation device includes a plurality of the operation unit and the display unit as a pair.

According to such a configuration, during the reading of Braille by the user, the finger of the user is adjacent to the operation unit corresponding to the Braille being read or another operation unit (for example, the operation unit corresponding to the Braille being read). Even when approaching the operation unit), the energization of the electrostatic element can be suppressed.

Further, in the operating device, the reading surface of the Braille member is transparent.

According to such a configuration, the notation of the display unit can be visually recognized even if the Braille member is arranged on the display unit. As a result, it is not necessary to newly write the Braille member, and the cost can be reduced.

Further, the operating device corresponds to a plurality of capacitive operation units that accept operations when the user realizes a predetermined function and do not accept operations when the users operate at the same time, and the operation units in the vicinity of the operation units. Braille having a plurality of display units on which the functions to be used are described, a reading surface located on the display unit and having Braille corresponding to the display unit formed, and a conductor between the operation unit and the operation unit. It is equipped with a member.

According to such a configuration, since the Braille member has a conductor between the Braille member and the operating portion, simultaneous energization (ghost) of two or more electrostatic elements is performed while the user's finger is in contact with the reading surface. ) Will be positively generated. Therefore, during the reading of Braille by the user, the user's fingers approach the operation unit corresponding to the Braille being read or another operation unit (for example, the operation unit adjacent to the operation unit corresponding to the Braille being read). However, the energization of the electrostatic element can be suppressed. As a result, it is possible to suppress an unintended operation (erroneous operation) during Braille reading by a visually impaired user.

Further, in the operating device, the operating unit has a single electrode and accepts the operation based on the capacitance between the electrode and the human body.

According to such a configuration, the detection method of the operation unit is a self-capacitance method that detects based on the capacitance that increases as the human body (user's finger) approaches a single electrode that is an electrostatic element. Therefore, the operation device has a simple structure and good sensitivity.

According to one aspect of the embodiment, it is possible to suppress an unintended operation during the reading of Braille by the user.
