Instrument, control method, and computer readable recording medium

A control method executed by an instrument that includes operating units configured to be operated by a user, the control method comprising:

• generating pieces of setting information for assigning operation functions to respective operating units configured to be operated by a user;
• assigning the operation functions to the respective operating units based on first one of the pieces of setting information;
• setting one of the operating units as a setting operating unit to which an operation function for switching the first one of the pieces of setting information to second one of the pieces of the setting information assigned to the setting operating unit is assigned;
• changing, upon a first operation of the setting operating unit, the operation functions of the operating units based on the second one of the setting information and inhibiting a change in the operation function assigned to the setting operating unit;
• and
• returning, upon a second operation of the setting operating unit after the first operation of the setting operating unit, the operation functions of the operating units to the operation functions assigned before the first operation of the setting operating unit.

A non-transitory computer readable recording medium on which an executable program is recorded, the program instructing a processor of an instrument including operating units configured to be operated by a user to execute:

• generating pieces of setting information for assigning operation functions to respective operating units configured to be operated by a user;
• assigning the operation functions to the respective operating units based on first one of the pieces of setting information;
• setting one of the operating units as a setting operating unit to which an operation function for switching the first one of the pieces of setting information to second one of the pieces of the setting information assigned to the setting operating unit is assigned;
• changing, upon a first operation of the setting operating unit, the operation functions of the operating units based on the second one of the setting information and inhibiting a change in the operation function assigned to the setting operating unit;
• and
• returning, upon a second operation of the setting operating unit after the first operation of the setting operating unit, the operation functions of the operating units to the operation functions assigned before the first operation of the setting operating unit.
