A control device includes: a print data acquisition unit configured to acquire print data, which is formed of a plurality of lines and indicates a coloration state of each pixel included in the plurality of lines; a head drive unit configured to supply, to a thermal head formed of a plurality of heating elements each corresponding to the pixel, an electric current for heating the thermal head for each pixel; a motor drive unit configured to supply, to a motor configured to move heat-sensitive paper relative to the thermal head, a drive current for step driving the motor for each line; a speed control unit configured to control, based on the number of colored pixels of a determination subject line among yet-to-be-printed lines of the print data, a relative moving speed of the heat-sensitive paper moved by the motor; and a preheating control unit configured to cause the head drive unit to output, when the determination subject line is a specific line being a line in which the number of colored pixels of the determination subject line exceeds a predetermined value, a preheating current being an electric current for heating the thermal head to such a degree as to prevent coloring of the heat-sensitive paper by a time the specific line is printed.

Alkaline batteries including a positive electrode, a negative electrode, a separator, and an electrolytic solution which are accommodated in a container are provided. The electrolytic solution is a potassium hydroxide aqueous solution having a concentration of 40% to 50%. The negative electrode consists of a gel-like negative electrode mixture containing a negative electrode active material and an alkaline aqueous solution. The alkaline aqueous solution contains potassium hydroxide and sodium hydroxide in a molar ratio range of 89:11 to 96:4. The positive electrode consists of a positive electrode mixture including a positive electrode active material containing silver oxide and manganese dioxide, and a blending ratio of manganese dioxide in the positive electrode mixture is 25% to 50% by mass.

To provide a rolling bearing excellent in long-term durability. A rolling bearing includes: an inner ring and an outer ring disposed coaxially with each other; a rolling element disposed between the inner ring and the outer ring; a seal member mounted on the outer ring and configured to cover a space between the inner ring and the outer ring from an outside in an axial direction; and grease disposed between the rolling element and the seal member. The grease is in contact with an inner circumferential surface of the outer ring and the seal member. Unworked penetration of the grease is more than 178 and less than 287.

A printer is configured to perform printing on a linerless label including a pressure-sensitive adhesive surface formed on a back surface of the linerless label. The printer includes: a casing including: a receiving portion configured to receive the linerless label before printing; and a delivery slot through which the printed linerless label is delivered; a printing unit including: a thermal head, which is arranged inside the casing, and is configured to perform printing on the linerless label; and a platen roller, which extends in a width direction of the linerless label, and is configured to convey the linerless label toward the delivery slot while sandwiching the linerless label between the platen roller and the thermal head; and a sensor configured to detect the linerless label located between the printing unit and the delivery slot. The casing includes a guide surface to be opposed to the pressure-sensitive adhesive surface of the linerless label that has passed through the printing unit. The guide surface includes: an upstream portion, which includes a plurality of upstream ribs formed upright at intervals in the width direction to extend along a conveying direction of the linerless label; a downstream portion, which is provided at a distance from the upstream portion on a downstream side in the conveying direction, and includes a plurality of downstream ribs formed upright at intervals in the width direction to extend along the conveying direction; and a midstream portion, which is provided at the same position as that of the sensor in the conveying direction, is located between the upstream portion and the downstream portion, and includes at least one midstream rib formed upright only on a center portion of the midstream portion in the width direction to extend along the conveying direction.

The rolling bearing includes an inner ring and an outer ring that are disposed coaxially with each other, a rolling body that is disposed between the inner ring and the outer ring, and a resin cover that is mounted on the outer ring. The outer ring has an outer circumferential surface that faces an opposite side of the inner ring, and an end surface that faces an axial direction. The resin cover has a circumferential wall portion that covers the outer circumferential surface, and a flange portion that is connected to the circumferential wall portion and covers the end surface. The flange portion has an opening portion formation region that has a constant width in a radial direction, extends over an entire circumference, and is formed with opening portions that expose the end surface.

A portable terminal has a thermal head. The portable terminal includes a first sensor unit configured to detect presence or absence of a sheet, a second sensor unit configured to detect information related to a mark provided on the sheet, and a sheet determination unit configured to determine a kind of the sheet. The sheet determination unit is configured to determine a kind of the sheet based on a result of detecting information related to the mark with use of the second sensor unit after the sheet is conveyed in a reverse direction with respect to a direction of discharging the sheet.

A printing system includes a portable terminal including a thermal head; and a host device configured to control label printing performed by the portable terminal. The host device includes a label generation module configured to generate the new label by adjusting, based on information relating to an object included in existing label data and a size of a new label, one or both of a position and a size of the object in the new label.

A thermal printer includes: a housing; a platen roller supported on the housing so as to be rotatable; a thermal head housed in the housing and arranged so as to be opposed to the platen roller; and a paper guide that forms a sheet passage for a sheet between the housing and the paper guide, and is pivotally supported on the housing so as to be pivotable about a pivot axis between a guide position at which the sheet is allowed to be fed between the platen roller and the thermal head, and an open position at which the sheet passage for the sheet is exposed.
