A tape cartridge including an improved housing is disclosed. The housing has a base plate on which tape packs are rotatably mounted and a cover secured to the base plate and having an opening. A transparent panel is fitted to the opening of the cover and allows a light to pass from an outside to an inside of the housing. The transparent panel has on peripheral portions thereof projections engageable with grooves which are formed on peripheral portions of the cover adjacent the opening.

A printer includes a print head and a platen roller facing the head. The platen roller is supported by supporting frames. The frames are rotatably supported by a stationary shaft. A second set lever is mounted on the supporting frame to be movable integrally with the frames, and includes a pressing portion facing a paper guide. The paper guide is pressed against a feed roller for feeding a paper sheet passing between the head and the platen roller. When the supporting frames are rotated in a direction to leave the platen roller from the head by a first set lever, the pressing portion pushes the paper guide so as to leave it from the feed roller.

A label printer comprises a supporting frame having a pair of side plates facing each other. A platen roller and a head unit having a print head are arranged between the side plates. A supporting shaft extends parallel to the platen roller and has one end fixed to one of the side plates and a free end adjacent to the other side plate. The head unit is supported on the supporting shaft and located in an operative position wherein the print head is opposite to the platen roller. The head unit is slidable from the operative position to the outside of the supporting frame along the supporting shaft. The free end of the shaft and the head unit in the operative position is fixed by a fixing member mounted on the other side plate.

A tape cassette comprises a supply and a take-up reel on which tape is wound, a cassette casing for rotatably enclosing the reels therein, a plurality of tape guide pins, each being press-fitted through the inner wall of the casing, for defining a tape path for the tape travelling between the pair of reels. The press-fit section of each guide pin is formed in a predetermined taper in such a manner as to gradually decrease its outer diameter towards its end. The straight press-fit section of the guide pin is formed in such a manner as to include a predetermined geometry of chamfered circumference at its end. In a tape guide pin used in conjunction with a tape guide roller, grease having a predetermined viscosity coefficient is disposed between the associated pin and roller. An electrical insulating cover is provided for surrounding the exposed underside of the electrically conductive lower half of the casing.

A thermal printer comprises a pair of fixed frames for rotatably supporting a platen which is rotated by a motor and a head unit rotatably supported by the fixed frames through a pair of movable frames and for supporting a thermal head. A pair of pinch rollers are rotatably mounted on the fixed frames, which are selectively brought to a first operating state to feed a paper sheet to the region between the platen and the thermal head, and a second operating state to feed no paper sheet. The thermal head is selectively moved between a first position, in which it is pressed against the platen, and a second position in which it is disengaged from the platen. The thermal head is moved to the first position, at the same time the pinch rollers and moved to the second operating state, while the thermal head is moved to the second position, at the same time the pinch rollers are moved to the first operating state.

A highly reliable resin-molded stator not suffering insulation breakdown between the different phases of the stator coils even when the operation mode where the output of a rotary machine using a resin-molded stator in which a stator coil wound around a plurality of slots and a stator coil provided at the stator core end are resin-molded is to be increased from the level under a stopped status to the maximum achievable level within a short time is repeated. Also disclosed is a method of manufacturing such a stator, and a rotary machine using the same. The resin-molded stator of the present invention comprises a stator core, electrically insulated stator coils wound around the plurality of slots or protrusions provided in the axial direction of the stator core, and molding resin with which are molded the stator core and the stator coils located at the aforementioned slots or protrusions and at the stator core end, wherein the resin-molded stator is characterized in that non-adhesive structure is established between the molding resin and at least one of the end faces of the stator core.

A rotary sensor that outputs two analog signals, such as one sine wave and one cosine wave and has multiple periods within one period of the electrical angle of a motor is employed. The motor is energized at each position for a specified length of time upon its startup by using multiple electrical angles corresponding to the multiple candidate absolute angles obtained from the rotary sensor signal as the initial position of the motor, and the electrical angle at which the motor acceleration becomes maximum is determined as the absolute angle. While the motor drive is in operation, on the other hand, the phase difference Δθ between the phase of the motor at the counter electromotive voltage and the control phase is directly computed from the parameters of the motor, sensed current, voltage command and angle speed so as to correct the shifted position. A high-efficiency motor drive unit with improved maintainability of rotary sensor and improved accuracy of sensing the magnet pole position of a permanent magnet synchronous motor that accelerates and decelerates very quickly in a wide range of speed is realized.
