An operation switch press erroneous-detection avoidance device, if an operation on an operation switch is performed by an approaching object to the operation switch, in a case where the operation on the operation switch is detected during a period when an event which occurs in association with the operation on the operation switch occurs, prohibits a process associated with the operation switch from being activated.

A switch operation erroneous-detection avoidance device includes: an execution control unit that if a prescribed device executes a prescribed process with a portable object when an operation switch transits from a pressed state to an unpressed state, prohibits execution of a process associated with the operation switch and if the prescribed device does not execute the prescribed process with the portable object when the operation switch transits from the pressed state to the unpressed state, permits the execution of the process associated with the operation switch.

A cassette connectable to a printer includes a housing configured to house a recording sheet, a connector that is connected to a feed port of the printer for supplying the recording sheet to the printer, and a sensor group including sensor modules that measure a state in a space surrounded by the housing.

An information processing apparatus includes a display unit, a first detection unit that detects a position of an object located in a vertical direction with respect to the display unit and that interacts with the display unit in a contactless manner, wherein detecting the position results in detecting an instruction associated with the at least one input object that is displayed on the display unit and corresponds to the position of the object, a second detection unit configured to detect confirmation of the instruction detected by the first detection unit, and an input unit configured to input data corresponding to the at least one input object in a case where the second detection unit detects confirmation of the instruction associated with the at least one input object in a state where the first detection unit detects the instruction associated with the at least one input object.

A switch operation erroneous-detection avoidance device includes: an execution control unit that if a prescribed device executes a prescribed process with a portable object when an operation switch transits from a pressed state to an unpressed state, prohibits execution of a process associated with the operation switch and if the prescribed device does not execute the prescribed process with the portable object when the operation switch transits from the pressed state to the unpressed state, permits the execution of the process associated with the operation switch.

Apparatus(es) and method(s) relating to operation of a multi-function printer panel are disclosed. In such a method, a main menu is displayed on a display screen of the multi-function printer panel. A plurality of primary image items of the main menu displayed on the display screen are navigated responsive to a first movement of a dial control. The dial control is pressed to select a primary image item of the plurality of primary image items. A plurality of secondary image items displayed on the display screen associated with the primary image item selected are navigated responsive to a second movement of the dial control. The dial control is pressed to select a secondary image item of the plurality of secondary image items.

A digital camera with a printer includes an imaging unit, a print unit that prints an image on a medium and discharges the printed medium, a display unit, a first operation member that is rotated from a first position in a first direction around a rotation axis against biasing force, and is rotated in a second direction opposite to the first direction by the biasing force to be returned to the first position in a case in which the first operation member is released, and a processor. The processor performs specific control in accordance with operation of the first operation member.

An image forming apparatus includes an apparatus body having a cartridge accommodation portion, an opening/closing member attached to the apparatus body and being movable between a first position at which the cartridge accommodation portion is exposed to the outside of the image forming apparatus and a second position at which the opening/closing member covers the cartridge accommodation portion and an operation panel unit for operating the image forming apparatus. The operation panel unit has: a sheet portion; and a switch portion to transmit a user's operation to the image forming apparatus via the sheet portion. The sheet portion provided in the opening/closing member is disposed at such a position as to at least partially overlap the cartridge accommodation portion on an insertion/removal trajectory of the cartridge and to cover the switch portion provided in the apparatus body in a state in which the opening/closing member is at the second position.

The processor of a printer prints a setting value settable in a setting item of one in which a setting value is set on a print medium on the basis of input to an input section in a setting mode for setting a setting value in the setting item of one. If the first setting value of the setting item of one is stored in a memory, the processor causes a printing mechanism to print a first image in association with the setting value corresponding to the first setting value of the setting item of one out of the setting values to be printed. If the first setting value is not stored, the processor causes the printing mechanism to print the first image in association with the setting value corresponding to a second setting value of the setting item of one out of the setting values to be printed.

A switch operation erroneous-detection avoidance device includes: an execution control unit that if a prescribed device executes a prescribed process with a portable object when an operation switch transits from a pressed state to an unpressed state, prohibits execution of a process associated with the operation switch and if the prescribed device does not execute the prescribed process with the portable object when the operation switch transits from the pressed state to the unpressed state, permits the execution of the process associated with the operation switch.
