摘要:
A printer includes a thermal head configured to print information on thermal paper, a platen roller configured to press the thermal paper against the thermal head and a paper feed unit configured to convey the thermal paper. The printer further includes a control unit configured to control the paper feed unit to convey a leading edge of the thermal paper to a print waiting position between the thermal head and the platen roller, and also configured to control the paper feed unit to move the leading edge of the thermal paper from the print waiting position to a retracted position upstream the print waiting position.
摘要:
A temperature sensor having a weld zone between an element electrode wire and a sheath core wire. When a section of the weld zone is taken orthogonally to the axial direction and in such a manner as to pass through a center point, L/D is greater or equal to 0.6, wherein D represents the diameter of the element electrode wire, and L represents the length of a chord connecting a first weld point and a second weld point as defined herein.

Embodiments described herein are to a printer which includes a first head configured to print a first data set on a first side of a paper being conveyed along a paper path, and a second head configured to print a second data set on a second side of the paper being conveyed along the paper path. The printer further includes a sensor provided at an upstream side of the first and second heads in the paper feeding direction along the paper path and configured to detect an end portion of the paper being conveyed along the paper path. The printer further includes a control unit, when the end portion of the paper is detected by the sensor, configured to allow the first and second heads to continue a printing operation until the first and second data sets are printed on the remaining portion of the paper.
摘要:
Movement of platen rollers are started at a predetermined timing considering the distance from a paper sensor to thermal heads, and a paper feeding speed, so that the movement of the platen rollers is completed at the time when the thermal paper reaches the thermal heads.

A control negative has at least a frame which has a center eye portion reproducing a neutral gray on a reference print formed under optimum exposure conditions, and a background area consisting of a gray base portion and a plurality of color chips dispersed over the gray base portion. The gray base portion reproduces a neutral gray and each color chip has a specific color on the reference print. A couple of portraits are disposed on opposite horizontal sides of the center eye portion, to represent an upper and a lower limit of flesh tone on the reference print. A density control chart and a color control chart are disposed in the same horizontal center line as the center eye portion. The density control chart has white and gray areas disposed adjacent to each other. The color control chart has a gray area and a color scale consisting of a series of color segments. The color segments have color densities unbalanced by a constant degree from an equivalent neutral density of the gray area toward individual directions so as to have different hues from each other on the reference print.

A member to be coated is placed in a hollow portion of an external member and a coating material is charged in a gap between the member to be coated and the external member. The member to be coated has another member fixed thereto. The member to be coated is drawn from the hollow portion of the external member to form a coated film thereon.

In a thermal printer, a first thermal head to print data on one surface of a print medium both surfaces of which are colored in different colors or a second thermal head to print data on the other surface of the print medium different from the print surface of the first thermal head is controlled, and a test image is printed on the print medium set in the thermal printer. Then, in the thermal printer, a print density of the printed test image is detected, and based on the detected print density of the test image and information stored in a density information storage section, it is determined whether the front and the back of the print medium set in the thermal printer is normal.
