A numerical key unit 70 mounted in a mounting portion 12 of an image forming apparatus 1 and card reader of inputting information to the image forming apparatus 1 includes a casing 71 mounted on the mounting portion 12, an operating key 100 comprised of a hardware key capable of inputting information on a numerical value, a substrate 73 provided inside the casing 71, a main assembly-side cable 76 connected to a connector 85 mounted on the substrate 73 and electrically connecting the image forming apparatus 1 and the numerical key unit 70, and a first opening 71a through which the main assembly-side cable 76 is inserted. The first opening 71a is provided on a bottom of the casing 71 so that in a thickness direction of the substrate 73, the main assembly-side cable 76 is exposed to an outside of the casing 71 from a surface on a side opposite from a surface where the operating key 100 is provided.

Provided is a printing device that performs printing using a recording material, the printing device including: an capacitive touch panel; a home operation portion including a mechanical key for transitioning from a screen displayed on the capacitive touch panel to a basic screen including information on a remaining amount of the recording material; and a power supply operation portion including a mechanical key for shifting a power state of the printing device, in which a panel installation surface provided with the capacitive touch panel is a surface different from a power supply operation portion installation surface provided with the power supply operation portion.

An input device is mountable on an image forming apparatus including a display portion capable of displaying information and is a numerical key unit 70 at least including a numerical key portion 110 consisting of a hardware key capable of inputting information on a numerical value and a start key 131 consisting of a hardware key capable of inputting information for starting predetermined processing. The start key 131 is disposed on a front side F than the numerical key portion 110 in a state in which the numerical key unit 70 is mounted on the image forming apparatus.

An operation unit is provided on a front side of the image forming apparatus. A document feeding portion feeds a document supported by a document supporting portion in a document feeding direction from a front side of the image forming apparatus toward the rear side of the image forming apparatus. A document discharge portion discharges the document in a document discharge direction from the rear side toward the front side. The operation unit is disposed on one side with respect to an apparatus center of the image forming apparatus in a left-right direction orthogonal to a direction from the front side to the rear side. A conveyance center of the document feeding portion in the left-right direction is disposed on the other side with respect to the apparatus center in the left-right direction.

An input device including an operation key arranged in an opening of a panel is provided. The input device also includes a light source and a push button switch each being arranged in a position opposite an opening on a board. The operation key includes: a key top having a pressing part extending toward the push button switch. The pressing part is arranged in a position separated from a center position in planar view of the key top on a line that is parallel to a line connecting connection parts of the key top, which are connected with one pair out of one or more pairs of arms, and passes through the center position. The push button switch is arranged in a position on the board opposite an arrangement position of the pressing part.

An information processing apparatus includes a processor. The processor changes darkness of an image presented in mid-air in response to a sensor detecting a user performing a mid-air gesture on the image.

A system and method for maintenance and supplying of a fleet of multifunction peripheral devices includes two or more networked devices including a decision engine. Devices discover one another and one device is designated as a server. The server creates a virtual lobby accessible by other devices and its decision engine is enabled. The server invites other devices into its virtual lobby, and these devices join the lobby in response. Devices provide their device state information to the lobby. The enabled decision engine generates recommendations for consumable replenishment, device servicing or device configuration, relaying the recommendations to a system administrator's tablet or smartphone. The administrator may accept, reject, modify or implement received suggestions. Consumable supplies or servicing recommendations can be done automatically if enabled. Administrator actions are fed back to the server for machine learning to improve future suggestions.

Provided is a printing device that performs printing using a recording material, the printing device including: an capacitive touch panel; and a transport operation portion including a mechanical key for operating a transport position of a print medium for printing, in which a panel installation surface provided with the capacitive touch panel is a surface different from a transport operation portion installation surface provided with the transport operation portion.

Printing devices herein comprise an internal power supply within the body of the printing devices. Also, a processor and printing components are within the body and connected to the internal power supply. A user interface is external to the body and is connected to the processor and the internal power supply. The user interface has a universal serial bus (USB) connection. A USB hub structure is within the body and is connected to the processor, the internal power supply, and the user interface. The USB hub structure includes an integrated circuit (IC), a power connector connected to the internal power supply, and a plurality of USB connectors connected to the IC. The USB connectors can extend through the body and one of the USB connectors connects the USB connection of the user interface to the processor and the internal power supply.

An example display system includes a power source, a communication transceiver operatively connected to the power source and wirelessly linked to a host device, a processor to receive computer-executable data signals from the host device through the communication transceiver, and a display device to receive the data signals from the processor and display status information of an attached compartment of the host device.
