Abstract: A printer has a function of restricting a number of printing during a particular period for each user ID. When printing is performed, a computer updates a counter value of the number of printing associated with a user ID corresponding to the printing, and restricts printing corresponding to the user ID when the counter value reaches an upper limit. When an individual operator is operated in an administrator PC, the computer initializes the counter value associated with the user ID corresponding the individual operator.

Abstract: A water discharge device comprising a water discharge member formed with a slit-like discharge port and a discharge path, wherein the discharge path is formed with a reservoir chamber for holding, as reserve water, water flowing into the discharge path from its upstream side, and is formed with a constricting flow path that sends forth the reserve water in the reservoir chamber to the discharge port, and lateral surfaces on either side of the discharge path in its width direction are formed such that a path width of the discharge path spreads as approaching its discharge port side from its reservoir chamber side, and is formed such that the angle formed by an imaginary line paralleling the width direction of the discharge port and, on the lateral surfaces, a tangent line passing over the discharge port's opening rim is greater than or equal to 45° and less than 90°.

Abstract: A plurality of supporting columns extend downwardly from a top wall of a cover attached to the electrical junction box body. A case surrounding the PTC element has projecting bars extending in the cover attaching direction. Each of the supporting columns has a guide groove receives the associated projecting bar so as to hold the case. The PTC element joints to connecting terminal strips having a heat radiation face. Further, the connecting terminal strip has a saw-tooth face at each side end thereof.
