Abstract: A printer includes a feeding portion, a guide portion, and a processor. The processor determines whether a roll sheet in the printer is an inward facing roll sheet or an outward facing roll sheet. When the roll sheet is the inward facing roll sheet, the processor controls the feeding portion to move the downstream-side end portion of the print medium from the cutting position to an upstream side in the feed direction than the upstream end portion before the printing. And the processor controls the printing portion to start printing. When the roll sheet is the outward facing roll sheet, the processor controls the printing portion to start printing in a state in which a downstream-side end portion of the print medium in the feed direction is positioned further to a downstream side in the feed direction than an upstream-side end portion of the guide portion in the feed direction.

Abstract: A flow path switching valve has an injection side portion formed with an injection chamber and an outer valve seating surface, and a discharge side portion provided with a partition member formed with an inner valve seating surface. A discharge control block communicating with a discharge chamber is formed with a control flow path which is increased and decreased in volume by a discharge rod. To fill the control flow path with grease, a valve element closes an inner flow path and opens an outer flow path. On the other hand, to discharge the grease in the control flow path to the discharge chamber, the valve element closes the outer flow path and opens the inner flow path. After being supplied to the control flow path, the grease is supplied to the discharge chamber.
