A bill processing apparatus which is capable of reliably supplying information on a bill to the bill housing body side. The paper sheet processing apparatus has a bill housing part being capable of housing a bill inserted from a bill insertion slot, and also a reader/writer which wirelessly transmits information on the bill inserted from the bill insertion slot. The bill housing part has a coil antenna which wirelessly receives the information transmitted from the reader/writer, and a storage part which stores the information on the bill received from the coil antenna.

An image recording apparatus includes a conveyance mechanism conveying a sheet-shaped medium in a conveyance direction, a recorder recording an image on the sheet-shaped medium conveyed by the conveyance mechanism, and a controller. The controller receives image data including one or a plurality of images, each of the images being to be recorded on one page, from an external apparatus, and determines whether to perform a combination-recording in which a plurality of images are aligned in the conveyance direction and recorded on a single sheet-shaped medium. In a case where image data including the plurality of images is received and it is determined that the combination-recording is to be performed, the controller causes the conveyance mechanism to convey a single sheet-shaped medium, and causes the recorder to record a plurality of images aligned in the conveyance direction on the single sheet-shaped medium.

An ultrasonic apparatus includes a first ultrasonic sensor that transmits an ultrasonic wave to an object and receives the ultrasonic wave reflected by the object, a second ultrasonic sensor that transmits an ultrasonic wave to the object and receives the ultrasonic wave reflected by the object, an determination circuit that outputs an error signal when the difference between a first distance between the first ultrasonic sensor and the object calculated based on ultrasonic wave transmission and reception processing using the first ultrasonic sensor and a second distance between the second ultrasonic sensor and the object calculated based on ultrasonic wave transmission and reception processing using the second ultrasonic sensor is equal to or greater than a threshold value.

An elongated-object drum includes: a drum on which an elongated object is wound; and a management module that is attached to the drum and comprises: an acceleration sensor that detects acceleration of the drum, a computation device that performs computation based on a detection result from the acceleration sensor, and a storage device that stores a computation result obtained by the computation device based on the detection result from the acceleration sensor.

An image forming apparatus comprises an accommodating unit that accommodates recording materials and a feeding unit that feeds an accommodated recording material, detects a fed recording material, and measures time from a predetermined timing until a recording material is detected. An information processing apparatus receives measured time data from the image forming apparatus, classifies the received plurality of time data into a first group and a second group in accordance with a length of time, selects a group for predicting a remaining life time of the feeding unit from the classified first group and second group, and predicts a remaining life time of the feeding unit using time data included in the selected group.

A bill processing apparatus which is capable of reliably supplying information on a bill to the bill housing body side. The paper sheet processing apparatus has a bill housing part (100) being capable of housing a bill inserted from a bill insertion slot, and also a reader/writer (142) which wirelessly transmits information on the bill inserted from the bill insertion slot. The bill housing part (100) has a coil antenna (104c) which wirelessly receives the information transmitted from the reader/writer (142), and a storage part (104b) which stores the information on the bill received from the coil antenna (104c).
