Control panel and image forming apparatus

An image formation apparatus comprising:

• a control panel configured to receive an input of an operator;
• a main device configured to execute an operation instruction corresponding to the input;
• and
• a tilt changing section configured to change a tilt of the control panel relative to the main device in response to a movement of the control panel by the operator holding at least a part of the control panel,
• wherein the control panel includes
• a touch panel having a touch surface that is to be touched for the input,
• a control panel housing covering the touch panel except for at least a part of the touch surface,
• a proximity sensor configured to sense an object in the proximity of the control panel, and
• circuitry, and
• wherein the circuitry
• determines a presence or an absence of an operation of the tilt changing section by the operator based on a result of the sensing of the object by the proximity sensor,
• outputs an operation instruction to the main device based on a touch input that is the input given by a touch on the touch surface, and
• refrains from outputting the operation instruction based on a determination that the tilt is changed, and
• wherein the control panel further includes a display section configured to display, for the operator, a display content that has been output from the circuitry,
• wherein, after the sensing of the object in the proximity by the proximity sensor, before determination as to whether the tilt is changed, the circuitry reduces a size of an input region in which the touch input is to be received, and
• wherein the circuitry outputs the operation instruction such that a size of a region in which the display content is to be displayed is reduced.
