Abstract: A media processing device enables conveying media fed from different paths into a common path in a stable conveyance state to the scanning position of a scanner. A check processing device has a path switching member that selectively bridges a back path for conveying checks and a card path to a downstream path, which is a common path. The path switching member changes position and switches the connected paths in conjunction with movement of a shutter that covers the open part of a nozzle cap used to cap the nozzle face of the inkjet head at the back path.

Abstract: A printer can suppress paper lifting away from the platen surface even when conveying strong paper (regardless of paper strength) (a printer that can suppress paper uplift from the platen and is not easily affected by the type of paper). A printer 40 in which the platen surface 42a is on the inkjet head 21 side of a plane C through position A where paper 11 is held by a conveyance roller 36, and position B where the paper is held by a discharge roller, has: on the printhead 21 side of the plane C between the platen 42 and conveyance roller 36, at least one entry angle control unit 44 that contacts the paper 11 conveyed toward the platen surface 42a, and controls the entry angle of the paper 11 to the platen surface 42a; and on the printhead 21 side of the plane C between the platen 42 and the discharge roller 37, at least one exit angle control unit 46 that contacts the paper 11 conveyed in the direction away from the platen surface 42a, and controls the exit angle of the paper 11 from the platen surface 42a.

Abstract: A control method of a media conveyance device enables accurately detecting media slack by a detection mechanism with multiple emitters and multiple photodetectors disposed opposite the emitters. A printer (media conveyance device) has a controller that controls a delivery mechanism, a conveyance mechanism that conveys media, a delivery mechanism, and a conveyance mechanism, and controls conveying roll paper; a first detector including a first emitter and first photodetector; and a second detector including a second emitter and second photodetector. When driving the conveyance mechanism, the controller selectively controls the first emitter and first photodetector to emit, and drives a spindle based on signal output from the first detector when first emitter emits, and signal output from the second detector when second emitter emits.
