An error detector determines whether or not there is a frequency error. In a case where it is determined that there is the frequency error, the error detector further determines whether or not the frequency error stays within a targeted error range. In a case where it is determined that the frequency error stays within the targeted error range, a proportional gain is decreased. In a case where it is determined that the frequency error fails to stay within the targeted error range, the proportional gain is increased. Then, a frequency proportional-integral-derivative operation processing is executed based on a set gain.

Upon completing a preparation operation including different processes, an image formation apparatus shifts to ready state in which image formation is executable, the processes including at least one process executed using a corresponding motor. The image formation apparatus comprises: an obtainer for obtaining, for each process, an estimated time period between start and completion thereof; and a controller for starting execution of, out of the processes, (i) one process whose estimated time period is the longest, then (ii) any other process so that any other process is executed in parallel with said one process. When said one process is included in the at least one process, the controller initiates the motor by high-speed initiation by applying thereto first voltage that is higher than second voltage. When any other process is included in the at least one process, the controller initiates the motor by normal initiation by applying thereto first voltage.

A human body sensing device comprises: an infrared sensor which detects a human body; a rotatable group of lenses having a plurality of lenses arranged around the sensor, the lenses being configured to: generate unit sensing zones defined by a sensing distance extending radially outwardly from the group and a small width extending in a rotation direction of the group; and form a plurality of alternating layers of a regional sensing zone including one or more than one of the unit sensing zones and a non-sensing zone not including any of the unit sensing zones, in a rotation direction of the group; a rotary drive which rotates the group; a rotation position sensor which detects a rotation position of the group; and a recognizer which recognizes the location and/or movement of a human body based on the output level indicated by the infrared sensor and the rotation position.

A human body sensing device being mounted on an object comprises: a first and second sensor being mounted on a vertical plane of the object and each having a pair of a positive and negative electrode; and a lens covering over the first and second sensors, wherein: the lens forms a sensing block in a sensing area constituting a plane perpendicular to the vertical plane, the sensing block including the positive and negative electrodes of the first sensor, and the positive and negative electrodes of the second sensor; either a first virtual line or an extended part thereof and either a second virtual line or an extended part thereof have a point of intersection in the sensing area; and the first and second virtual lines are symmetric with respect to a line perpendicular to the vertical plane of the object and passing through the point of intersection.
