Positions of a wire (33), which reciprocates by arc motion of a lever (36), within XY planes are regulated by means of a plurality of guides (35A-35D), each of which is composed of a pair of guide members (35a) and a warp preventing plate (35b). Thus, a deformation quantity of the wire (33) can be reduced when the wire (33) collides with a material to which printing is to be performed. As a result, frequency of generation of failures such as a bending damage and buckling of the wire (33) of a printing head (30) can be remarkably reduced. Furthermore, service-life of the printing head (30) and that of a device to which the printing head (30) is attached can be lengthened.

When a pattern is formed on the next object (200), feedback control is carried out on the basis of the read code management information. This enables precise and continuous formation of patterns such as the two-dimensional code on the object (200).

While moving a head having a plurality of equidistantly arranged engraving pins stepwise in a lateral direction, and when forming a code matrix (CM) comprising a plurality of dots on an engraved surface, a control unit sequentially positions the head such that the distance the head travels in the lateral direction does not become significantly larger, and such that adjacent dots are formed by different engraving pins. Through the above, errors arising when the head is moved in a wide step are dispersed, and as a result, the dots constituting a pattern can be formed accurately in a matrix shape.
By arranging engraving pins (33) around a vertical axis (L) and along the circumference of a circle centered on the vertical axis (L), the engraving pins (33) have identical orientation. This configuration limits the incidence of dot placement deviance caused by engraving pin (33) position, and dots are formed at an accurate pitch on the engraving surface. Further, as there is no difference in orientation between engraving pins (33), there is reduced variation in engraving pin (33) speeds at time of contact with the engraved surface, and it is possible to easily create dots of uniform size on the engraved surface.

A coil bobbin (50) comprises a cylindrical body portion (55) on which a coil (49) is wound, a pair of flange portions formed at both sides of the body portion (55), and terminal portions (51a, 51b) which are formed on the pair of flange portions, respectively, and on which the ends of the coil (49) are wound. The flange portions have thick portions (52a, 52b) and thin portions (53a, 53b), which are different in thickness, and are so formed as to become gradually thinner from the thick portions (52a, 52b) toward the thin portions (53a, 53b). The terminal portions (51a, 51b) are formed on the thick portions (52a, 52b), respectively.

An imaging device (1) having an imaging board (11) having an imaging element (12) mounted on its object side, an optical unit (20) including lenses (22, 23, 24) for focusing object light on the imaging element (12), blades (33, 34, 35) for adjusting the object light entering into the lenses (22, 23, 24), and a blade drive unit (30) including a step motor (36) as the drive source for the blades (33, 34, 35) and also including a motor board (39a) for supplying drive electric power, coming from the imaging board (11), to the step motor (36). The optical unit (20) is provided on the imaging board (11). The drive unit (30) is provided on the optical unit (20), separated from the imaging board (11). The motor board (39a) is provided on the blade drive unit (30) so as to face the imaging board (11). Solder (41) for electrically connecting the imaging board (11) and the motor board (39a) is provided between the boards (11, 39a).
A shutter drive device for a camera has a lower board (50) having an opening (51), a blade (70) for opening and closing the opening (51), and an electromagnetic actuator as the drive source for the blade (70). The electromagnetic actuator has an excitation coil (40), a rotor (20) magnetized with poles in the circumferential direction, a shaft (52) for rotatably supporting the rotor (20), and a stator (10) for generating magnetic force to the rotor (20) by conduction of electricity to the excitation coil (40). The rotor (20) has an arm (31) extending outward from the center and also has a pin (32) engaging with the blade (70) and upstanding from the arm (31). The rotor (20), the arm (31), and the pin (32) are arranged within the thickness (B) of the coil (40), in the direction of the shaft (52).
A printer section (100) is provided with a printing head for ejecting an ink to a packaging film (1), and a drying heater (40) for blowing warm air for drying the ink adhered on the packaging film (1) after printing. The drying heater (40) is provided with an encoder (20), which has a first opening/closing member (47B) and a second opening/closing member (48B) capable of changing the quantity of the warm air to be blown to the packaging film (1), and detects the transfer speed of the packaging film (1) at a position to which the warm air is blown. The drying heater is also provided with a control section (64) for controlling the first opening/closing member (47B) and the second opening/closing member (48B) corresponding to the transfer speed of the packaging film (1) detected by the encoder (20).
A printer includes: a printing head which discharges ink onto a wrapping film (1); a drying heater (40) which blows out a warm wind toward the wrapping film (1) after printing so as to dry the ink attached to the wrapping film (1) and can adjust the temperature of the warm wind; an encoder (20) which detects the convey speed of the wrapping film (1) when it passes the position where the warm wind from the drying heater (40) is applied; and a control unit (64) which controls the temperature of the warm wind from the drying heater (40) in accordance with the convey speed detected by the encoder (20).
Highly reliable time information on a file attached to electronic mail is easily acquired. Upon receiving electronic mail before a transmission processing from an electronic mail server, a time-stamp adding apparatus (3) determines whether a file is attached to the electronic mail by an attached file presence determining section (301) and, if attached, takes the file from the electronic mail. The time-stamp adding apparatus (3) adds a time-stamp to each file by an electronic signature section (304), reattaches the file to which the time-stamp is added to the electronic mail by an electronic mail reconfiguring section (306), and returns it to the server.

An optical filter (10) is composed of a flat plate (11), a turning pin (12) and an operation pin (13). The flat plate (11) is provided with a transparent substrate (31), a resin layer (32) formed on the transparent substrate (31), and a CNT layer (33) formed on the resin layer (32). The CNT layer (33) is arranged on an uppermost layer. Since CNT dispersed in the CNT layer (33) has a characteristic of more absorbing light having a short wavelength, strength of ultraviolet reaching the resin layer (32) can be reduced by forming the CNT layer (33) on the uppermost layer, and dye dispersed in the resin layer (32) is prevented from deteriorating. Thus, the optical filter (10) is provided with excellent resistance to environment.
