Provided is a printing device for which configuration is simplified and with which the ink ribbon can be appropriately fed in both directions between a supply roll and a take-up roll on which the ink ribbon is wound. The printing device (1) is provided with: a supply roll (4), a take-up roll (5), and a power transmission mechanism (31) for transmitting motive power from a drive source (30) to the supply roll (4) and the take-up roll (5). If the direction in which the take-up roll (5) winds the ink ribbon (3) is called the ribbon winding direction and the direction in which the supply roll (4) winds the ink ribbon (3) is called the ribbon rewinding direction, the power transmission mechanism (31) is provided with: a one-way clutch for transmitting the driving force of the drive source (30) to the take-up roll (5) in the ribbon rewinding direction; and a one-way clutch for transmitting the driving force of the drive source (30) to the supply roll (4) in the ribbon winding direction.

Provided is a magnetic head that can prevent illegally obtaining magnetic information of a card, and furthermore can be downsized. A magnetic head 3 includes: a core; a coil wound on the core; terminals 5 to which ends of the coil are connected; a substrate 8 on which mounted are a demodulating electronic component 6 for demodulating an analog output signal output from the terminals 5 to create a digital demodulated signal, and an encrypting electronic component 7 for encrypting the demodulated signal to create an encrypted signal; a cable 9 for electrically connecting the demodulating electronic component 6 and the terminals 5; and a case body 11 for storing the core, the coil, the terminals 5, and the cable 9. The demodulating electronic component 6 is mounted on one side 8a of the substrate 8, and in the meantime, the encrypting electronic component 7 is mounted on the other side 8b of the substrate 8. The substrate 8 is fixed to the case body 11 in such a way that the demodulating electronic component 6 is placed inside the case body 11 while the encrypting electronic component 7 is placed outside the case body 11.

[Problem] To provide a method and an apparatus for magnetic character recognition that enable magnetic character recognition with high accuracy, even when the magnetic ink characters are printed, having their character pitch and character width that are unusual. [Means to Solve the Problem] A method for magnetic character recognition includes: a peak detection process for detecting peak positions in a regeneration waveform; a character pitch measuring process for calculating an average character width and an average character period of each character according to a detection result of the peak detection process; a character segmentation process for calculating a peak interval array for each character according to the average character period; a peak searching process for searching for peak positions by using searching conditions, which are different from what the character segmentation process applies, on each waveform part segmented through the character segmentation process; a peak count evaluation process for choosing either a result of the character segmentation process or a result of the peak searching process, depending on whether the number of peaks in the waveform part agrees with a prescribed number of peaks; and a character determining process for a matching operation on a peak interval array, according to the peak interval array determined through the peak count evaluation process, to determine the character.

A valve driving device comprises an electric multi-way valve which simultaneously drives a plurality of valve bodies. A pinion 17 which is integral with a rotor of a motor for controlling a three-way valve 12 is a driving gear. Driven gears 20A and 20B which mesh with the driving gear are disposed substantially symmetrically with respect to a shaft of the driving gear. Valve bodies 24A and 24B provided on lower surfaces of the driven gears 20A and 20B slide on valve seats provided on valve seat plates 13. Communication holes (valve openings) 25A and 25B for a refrigerant outflow pipe which are welded to the valve seat plates 13 are opened or closed to interrupt or open a flow-path from an inflow hole 27. The two communication holes 25A and 25B can select the following four modes for the inflow hole 27: (a) A and B are opened, (b) A is opened and B is closed, (c) A and B are closed, and (c) A is closed and B is opened.
