The present invention relates to a printing apparatus having a function of calculating a remaining amount of a medium, comprising: a feed roller for winding a printing medium therearound and supplying the printing medium while being rotated; a printhead for performing printing on the print medium fed from the feed roller; a recovery roller around which the printing medium printed by the printhead is wound; and a control unit for controlling driving of the feed roller, the printhead, and the recovery roller, wherein a displacement measuring unit for measuring the remaining amount of the printing medium wound around the feed roller is disposed between the feed roller and the printhead.
The present invention relates to a printing device having a medium thickness calculation function, comprising: a feeding unit for feeding a printing medium; a collection unit for collecting the printing medium; a head unit which is provided between the feeding unit and the collection unit and records an image on the printing medium; a control unit for controlling operations of the feeding unit, the collection unit, and the head unit; and a thickness detection unit provided adjacent to the feeding unit to detect the thickness of the printing medium.
The present invention relates to a device for supplying and recovering printed material used in digital printing with which a long printed material can be simply mounted onto a digital printing apparatus so that the work efficiency of an operator can be improved. The present invention includes: a supply roll around which the printed material is wound; a first transport roll which transports the printed material supplied from the supply roll to the lower part of a head part; a second transport roll which discharges the printed material on which printing is completed by the head part; and a recovery roll which has an axis of rotation parallel to the axis of rotation of the supply roll and which is rotated by a recovery driving means so that the printed material discharged from the second transport roll is wound. The printed material is supplied when one end thereof is unwound from the supply roll and is fixed to the recovery roll through the upper sides of the first transport roll and the second transport roll.

Disclosed is a head alignment assembly in which a deviation of the head can be aligned conveniently with simple operation from the outside of the printer head section. The head alignment assembly includes a base plate to which at least one head unit is fixed to be exposed downward by a first head support block and a second head support block; a first fine adjustment section configured to shift the first head support block in a longitudinal direction of the head unit; and a second fine adjustment section configured to shift the second head support block in a transverse direction orthogonal to the longitudinal direction of the head unit. The first fine adjustment section includes a first push rod supported by fixed guides which are fixed on the base plate to press the first head support block; and a first handle fixed to one end of the first push rod to move the first push rod in the longitudinal direction. The second fine adjustment section includes a second push block configured to press the second head support block in the transverse direction; a second push rod supported by a plurality of fixed guides which are fixed on the base plate; and a second handle fixed to one end of the second push rod to move the second push rod in the axial direction.

The present invention relates to a head alignment device able to align displacement of a print head in a straightforward fashion by means of a simple action on the outside of a head part, and the invention comprises: a base plate for securing one or more head units in such a way as to be exposed downwards due to a first head supporting block and a second head supporting block; a first fine-adjustment part for repositioning the first head supporting block in the length direction of the head unit; a second fine-adjustment part for repositioning the second head supporting block in a width direction perpendicular to the length direction of the head unit. The first fine-adjustment part comprises: a first push rod which braces the first head supporting block and is supported on a securing guide secured to the base plate; and a first handle for moving the first push rod in the axial direction. The second fine-adjustment part comprises: a second push rod which is formed so as to have a second push block for pressing the second head supporting block in the width direction, and is supported on a securing guide secured to the base plate; and a second handle for moving the second push rod in the axial direction.
The present invention relates to a method for manufacturing Braille-printed matter using a UV printer so as to be used by both non-disabled people and blind people, the method comprising the steps of: outputting a visual output part to a subject of output; and forming a Braille part using the UV printer so that the Braille part overlaps the visual output part, wherein, in the step of forming the Braille part, a refractive index of Braille is adjusted by repeating output at least twice using the UV printer in order to prevent the visual output part from being seen as distorted.
