A printing apparatus includes: a first blade that cuts a printing medium; a cutter motor; a drive gear that engages the first blade and is rotated by the cutter motor to drive the first blade; a rotator that rotates in conjunction with the drive gear; a photosensor that includes a light-receiving/emitting section including a light-emitting element and a light-receiving element and that includes a sensor substrate that outputs a first detection signal or a second direction signal in accordance with whether or not detection light emitted from the light-emitting element to the light-receiving element is blocked by the rotator; a first cutter frame that supports the photosensor; and a cover member that covers the sensor substrate between the cover member and the first cutter frame.

Printing apparatus

Printer

A ticket production device that cuts continuous recording paper printed with information and produces a ticket includes a paper conveyance means that conveys the recording paper through a paper conveyance path; a printing means that prints information on the recording paper conveyed by the paper conveyance means; a paper cutting means that cuts the recording paper on which information was printed into a ticket of a specific length; a paper position detection means that detects the position of the recording paper waiting at a paper exit; and a control means that integrally controls these other means. When the paper position detection means detects the position of the recording paper changed, the control means operates the paper cutting means and produces a ticket based on the detection result from the paper position detection means.

Ticket production device and ticket production method

A printing device and a positioning method of a printing device can accurately compensate for deviation between the intended conveyance of the print medium and the actual movement of the print medium when conveyed. A printerhas a conveyance motorthat can selectively convey print media forward and reverse; and a control unitcontrols the conveyance motorto convey the print medium. The control unitexecutes a specific sequence, and calculates the difference in the conveyance amount of the print medium in each direction when the conveyance unit is operated the same amount in both directions. This sequence includes changing from forward to reverse and from reverse to forward the same number of times, a first conveyance of the continuous paper M forward or reverse, and a second conveyance in the opposite direction as the first conveyance.

Printing device, printhead, and method of positioning print media in a printer

A scanner unit includes a scanner for imaging a print medium, a base unit that supports the scanner, a pressure feed roller disposed opposite the scanning surface of the scanner, a guide member for guiding the print medium to the scanner, a frame member that supports the pressure feed roller and the guide member, and a motor that drives the pressure feed roller. The frame member is supported pivotably to the base. In other embodiments the scanner unit can include a roller shaft such that the pressure feed roller is coaxially affixed to the roller shaft and the frame member supports the roller shaft, a first gear on the roller shaft, and a second gear that transfers drive power from the motor to the second gear.

Media processing apparatus and scanner unit

The magnetic data processing apparatus includes a magnetic head and a motor arranged to reduce noise due to leakage flux from the motor. The magnetic data processing apparatus may form a check processing apparatushaving an MICR headand a transportation motor, which is preferably a stepping motor. The MICR headand the transportation motorare positioned relative to one another so that the rotational axisof the transportation motoris aligned with the longitudinal axis of the head gapin the MICR head. In the head gapof the MICR headthe direction of the leakage fluxfrom the transportation motoris parallel to the long axis of the left and right head gap facesanddefining the head gap. Because the detection sensitivity of the MICR headis lowest in this direction, noise due to leakage fluxfrom the transportation motoris suppressed and the MICR headcan read magnetic ink characters with good accuracy.

Magnetic data processing apparatus and noise reduction method for such apparatus

A check processing device prevents or suppresses entry of ambient light to a transportation path rendered as a vertical slot between the base unit and opening and closing cover. The upstream-side transportation path partof a check processing deviceis a vertical channel defined by a base unit guide surfaceand the cover-side guide surfaceof an operable cover. The image scanning surfacesandof a front contact image sensorand back contact image sensorfor imaging the front and back sides of a checkare exposed at the cover-side guide surfaceand the base unit guide surface. A cover-side visorand a base-side visorare formed to the cover-side guide surfaceand base unit guide surfacedirectly above the image scanning surfacesand. These visorsandprevent or suppress ambient light from entering to the image scanning surfacesandeven if the width of the upstream-side transportation path partincreases.

Media processing device

A scanner unit that includes a scanner for imaging a print medium, a base that supports the scanner, a pressure feed roller disposed opposite the scanning surface of the scanner, a guide member for guiding the print medium to the scanner, a frame member that is supported pivotably to the base, and a motor that is supported on the base. The frame member supports the pressure feed roller and guide member and the motor drives the pressure feed roller.

An image scanner and image scanning method to reliably image scanned media in an image scanning apparatus with consistent quality. The image scanning apparatus may be included within a printerfor printing to the medium. The image scanning apparatus comprises a transportation mechanism for transporting a card C along a transportation pathfrom an insertion openingand an image sensorto image the card on the transportation path. Guide wallsguide the card C into alignment with the transportation path. The transportation mechanism conveys the card C in a forward direction toward the image sensorto a specified indexing position, and then in reverse toward the insertion opening. The image sensorimages the card C as the card C is transported in reverse from the indexing position. The card C is then discharged from the card insertion opening

Image scanner and image scanning method

Problem To provide technology for preventing a drop in image scanning quality due to penetration of external light and contact with an ink ribbon. Means of Resolution A scanner unitaccording to the present invention has a scanner headand a support memberfor supporting this scanner head. The scanner headhas a scanning surfacefor scanning with the paper supported pressed by scanner feed roller. A stepped support parthaving support surfacestopositioned to the scanner feed rollerside of the scanning surfaceis disposed to the edge of the scanning surface

Scanner unit and a hybrid apparatus using it

The media processing apparatus has a first transportation path for guiding the check, a second transportation path and a third transportation path that diverge from the first transportation path, a front scanner that is rendered along the first transportation path for imaging the first side of the check, a back scanner that is rendered along the third transportation path for imaging the second side of the check, and a path switching guide that guides a check from the first transportation path into the second transportation path or third transportation path.

Printer and medium transportation assembly

A print media processing apparatus having scanner feed rollers for holding and transporting print media against an image scanner appropriately controls the scanner feed roller position. The scanner feed rollers are opposite the image scanner, which is disposed along a vertical segment of a transportation path along which a check or form is transported. A roller retraction mechanism moves the scanner feed rollers between a closed position in which the rollers press against the scanning surface, and an open position in which the rollers are retracted therefrom. The scanner feed rollers retract to the open position a specific time after scanning ends. By delaying retraction of the rollers in this manner, the present invention solves the problem of a check or other print media, after having been processed and transported to the exit side of the rollers, from slipping down between the rollers and the image scanner into the vertical transportation path because the rollers opened as soon as scanning ends.
