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 the home operation portion is closer to the capacitive touch panel than the power supply operation portion.

In a printing system capable of supplying a sheet of a job having undergone print processing by the printing unit of a printing apparatus to a post-processing unit capable of executing at least a specific type of post-processing among a plurality of types of post-processes, when the target job requires the specific type of post-processing, the printing apparatus is inhibited from executing print processing of the job without explicitly determining a sheet necessary for the print processing of the job by a user using a user interface unit. When the target job does not require the specific type of post-processing, the printing apparatus is permitted to execute print processing of the job without explicitly determining a sheet necessary for the print processing of the job by the user using the user interface unit.

An input device that is mountable on an image forming apparatus includes a plurality of numerical keys arranged as hardware keys, a connector provided in a casing of the input device and configured to electrically connect the image forming apparatus and the input device, and a USB port provided in the casing and configured to USB-connect external equipment, which is different from the image forming apparatus, to the input device. As viewed in an up-down direction that the numerical keys are pressed, the USB port is provided on a front side surface of the casing.

Provided is a 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; and a power supply operation portion including a mechanical key for shifting a power state of the printing device, in which the home operation portion is located in a first direction of the capacitive touch panel, and the power supply operation portion is located in a second direction of the capacitive touch panel, and the first direction and the second direction are orthogonal or opposite directions.

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.

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.

An image forming apparatus reads a document mounted on a document positioning section by using an image reading section, and forms an image of the document on a sheet by using an image forming section. The sheet subjected to the image formation processing is mounted on a discharge tray via a discharge section. The image forming apparatus includes an operation unit that has a touch panel and that protrudes from a front portion of the image reading section, and a power button that is a hardware button provided on a back side of the operation unit and on a front portion of the image reading section.

An image processing apparatus includes a reading unit configured to read an original, a transmission unit configured to transmit image data to an external apparatus, a printing unit configured to print an image, a display unit configured to display the image, and a control unit configured to suspend a job executed by the printing unit in response to a selection of a key for suspending a currently executed job, display a list of jobs on the display unit, and cancel a job selected by a user from the displayed list of the jobs. The control unit displays a list of transmission jobs for the transmission unit to transmit the image data generated when the reading unit reads the original in response to the selection of the key during display of a main menu screen for accepting a selection of a function to be used.

An image forming system includes an image forming unit, a housing having a top face, an operation unit freely placed on the housing top face, a touch panel, and a supporting base. The image forming unit forms an image on a sheet. The operation unit is freely placed on the housing top face and accepts a user operation for causing the image forming unit to execute image formation. The operation unit includes a touch panel having a display face on which information about the image formation is displayed and accepting touch operation performed by a user. The supporting base supports the touch panel so that an inclination angle of the display face inclined with respect to the housing top face becomes one of 5 degrees or more and 45 degrees or less when the operation unit is placed on the housing top face.

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.
