A foil transfer device includes a foil transfer film cartridge, a housing, a display, a detector, and a controller. The foil transfer film cartridge includes a supply reel on which a foil film is wound. The housing allows the foil transfer film cartridge to be removably installed therein. The display is provided on the housing to display information. The detector detects foil film information in a state where the foil transfer film cartridge is installed in the housing. The foil film information includes at least one item selected from a group comprising a color of the foil, a width of the foil film, and a widthwise position of the foil film in a direction of the width of the foil film. The controller causes the foil film information detected by the detector to be shown on the display.

An image forming apparatus includes: a sheet feeding conveyor that feeds and conveys a recording medium to a conveyance path; an image former that performs image formation on the recording medium; a medium sensor that is disposed on an upstream side of the recording medium from the image former on the conveyance path and measures one or more sheet physical properties regarding the recording medium conveyed; a first hardware processor that determines a type of the recording medium on a basis of the sheet physical properties measured by the medium sensor; a second hardware processor that determines conveyance performance for the recording medium; and a third hardware processor that determines whether or not to perform the image formation on a basis of the conveyance performance in a case where the type of the recording medium determined by the first hardware processor is a type out of product specifications.

A sheet processing device separates a two-ply sheet in which two sheets are overlapped and partially bonded and sandwich a sheet medium between the two sheets. The sheet processing device includes a relay conveyance path, a sheet loader, and control circuitry. The sheet medium is fed from an image forming apparatus connected upstream of the sheet processing device through the relay conveyance path. The sheet loader loads at least one of the two-ply sheet and the sheet medium. The control circuitry performs a mixing mode to feed the two-ply sheet or the sheet medium from the sheet loader.

A conveyance apparatus includes a bearing rotator, an entrance rotator, an exit rotator, a first driver circuit, a downstream conveyor, a second driver circuit, and a recording medium detector. The entrance rotator receives a recording medium at a first position. The downstream conveyor receives the medium at a second position. As a process of removing the medium, the first driver circuit starts rotation operation after the second driver circuit starts driving the downstream conveyor and rotates the rotators for not less than a period of time for the medium to be conveyed from the first position to the second position. The second driver circuit continues driving the downstream conveyor for not less than a period of time for the medium to be conveyed from the second position to a position at which the medium is detected after the rotation operation of the first driver circuit is stopped.

A sheet feeder includes a controller configured to control an emitter to emit an ultrasonic wave toward a target sheet being fed along a sheet guide, control a measurer to measure a first reception intensity of a first component of the ultrasonic wave received by a receiver during a first period of time, control the measurer to measure a second reception intensity of a second component of the ultrasonic wave received by the receiver during a second period of time, and determine a feeding state of the target sheet in a detectable area between the emitter and the receiver within the sheet guide, based on the first reception intensity and the second reception intensity.

A paper sheet S is intermittently transported by a transport mechanism 6 and each processing unit 7, 8 operates while the transport mechanism pauses the transport operation. An information acquisition unit 9 obtains paper information from the paper sheet. A control unit 10 stores the paper information of the paper sheet to be processed for each processing unit, updates the data of the memory in a manner such that the paper information of the paper sheet associated with the previous processing unit is associated with the next processing unit every time the transport mechanism transports, and configures the settings of each processing unit for the next processing operation based on the paper information every time the processing operation of the processing unit is completed.

The present invention relates to Indexer table (1) for rotary and horizontal shifting of paper bunches. Said indexer table (1) having spider arms shifted in rotary manner through pinion gear and servo motor. The drive power is provided to auxiliary shaft (5) from main shaft (4) through the pulley (11) and belt (19d) configuration. The juxtaposed shafts receive the drive power from the auxiliary shaft (5) through universal joints (10). The cam (12) on each shaft rotates along with rotation of the shaft for reciprocal movement of spider arm (20). The actuator (13) actuates follower (13b) for open and close movement of bunch gripper (21). Said bunch gripper (21) grips bunch paper and then said driven shaft (14) rotates so that the spider arm (20) shifts bunch paper in rotary manner. After performing operation of bunch paper, the spider arm (20) shifts bunch paper to next platform.

A paper conveyance device includes a paper feed unit, a conveyance rotator, a conveyance guide, a multi-feed detection unit, and a control unit. The control unit causes an ultrasonic sensor to transmit an ultrasonic wave in a detection section. The control unit sets a detection execution section and a detection skip section in the detection section. The control unit does not determine whether multi-feed has occurred in the detection skip section. The control unit sets the detection skip section based on a time point at which vibration is applied to conveyed paper.
