Abstract: A first wheel mechanism and rotation detecting means for detecting rotation of the first wheel mechanism are provided within a casing. A second wheel mechanism for measurement is movable provided at the casing. The second wheel mechanism is located in a non-detecting mode at such a place as not to protrude outside the casing. When moved by a moving member, however, the second wheel mechanism partially protrudes from the casing and the rotation of the second wheel mechanism can be transmitted to the first wheel mechanism, whereby the rotation of the second wheel mechanism can be detected by the rotation detecting means.

Abstract: A manually operable sweeping-type compact printer apparatus includes a key entry unit, a display unit, a memory unit, an encoder and a printer unit which are mounted on a manually manipulatable housing. When the housing is manually moved over a printing medium with the printer unit in contact with the printing medium, data entered by the key entry unit is printed out on the printing medium. In the printer apparatus, only designated segments or lengths of data are printed out on the printing medium, independent of continued travel or movement of the housing. Also, even if the housing is moved over the printing medium at an unstable moving velocity, high printing quality can be realized by control of the printing head. Stop codes designating the end of a data segment can be automatically or manually inserted.

Abstract: A breath detection signal from a breath sensor section is converted to a digital breath detection signal, and when the value of the detection signal exceeds a preset value, a tone is generated. After the tone generation, a tone parameter of the tone being generated is controlled according to the value of said digital breath detection signal. When a predetermined period of time is elapsed from an instant when the digital breath detection signal exceeds a preset signal, initial breath data is generated in correspondence to the breath detection signal or preset value at that instant. The tone parameter of the tone at the time of the tone generation is controlled according to initial breath data. After the generation of the tone, the tone parameter of the tone being sounded is controlled according to after-breath data corresponding to the breath detection signal.

The liquid crystal composition optionally contains 10 wt % or less of a second liquid crystal material consisting of at least one liquid crystal compound having a positive dielectric anisotopy .DELTA..epsilon.. A liquid crystal display device is arranged such that the liquid crystal composition is interposed between a pair of substrates on which electrodes are formed.

Abstract: A string member and a string trigger switch mechanism associated with the string member are arranged on an instrument main body. The string member is extended on the instrument main body at a given tension. When the string member is deviated against the tension upon a string displace operation and is then released from its state of tension, a string trigger switch starts a switching operation. While the string member is displaced from its state of rest, the string trigger switch does not start a switching operation. The string trigger switch outputs a tone generation start instruction signal based on the switching operation, and this signal causes a musical tone generating apparatus to start generation of a musical tone. When the string member is plucked while depressing a pitch designating section arranged on the instrument main body, a musical tone at a selectively designated pitch is generated.

Abstract: An electronic musical instrument for causing a tone generator to generate a musical tone corresponding to a musical performance while controlling an envelope by operation of a pedal. An operated-amount signal generator is provided for detecting an operated amount of the pedal and for generating an operated-amount signal, and an effect adding unit is provided for controlling parameters for effect addition so as to add an effect to a musical tone generated from the musical tone generator in accordance with the operated-amount signal from the operated-amount signal generator. The operated-amount signal from the operated-amount signal generator is changed by the operation of the pedal, and an effect-adding parameter in the effect adding unit is changed accordingly, to thereby add an effect to the generated musical tone.

Abstract: In playing a music, the present electronic musical instrument stores a code for a performance event and data of generation time length until a presently-specified performance event is regenerated, in a sequencer memory. For each playback access to this sequencer memory, a performance event is excecuted upon elapse of a time corresponding to the generation time interval data of the performance event read out from the memory. For instance, a musical tone which is generated by depression of a key on a keyboard, is generated again with the designated pitch after a given time.

Abstract: A small-sized copying apparatus has a housing (1). As the housing (1) is moved, an image data-reading circuit (15, 56, 57, 58) receives the light reflected from an original illuminated by a light source (11), and the image data obtained from the light is written into memory (60). Further, as the housing (1) is manually moved, the image data stored in the memory (60) is printed by means of a printing device (21, 65). Any desired reading width over which an image is to be read by the reading circuit (15, 56, 57, 58) can be electronically and/or mechanically designated by designating means (10a, 10c, 61, 63, 64, 64a, 64b).

Abstract: A system for automatically determining principal tones of an accompaniment line supporting a melodic line comprises a plurality of principal tone inference engines which infer principal tones in accordance with different rules of inference from one another and a priority control which controls priorities among the plurality of inference engines to determine final principal tones in the accompaniment line. Each principal tone inference engine may include a condition checker which checks to see whether muscial conditions are met and a principal tone generator which generates principal tones. The priority control monitors the information supplied from the condition checkers to select final principal tones supplied from the principal tone generators. Some of the final principal tones may be dependent from the preceding principal tone while some others may be independent. There may also be provided a storage of the structure of music which is reflected in a series of the final principal tones.

Abstract: A musical tone generating device generates musical tones of a frequency in accordance with pitches which are extracted from input waveform signals by a pitch extracting means. When a pitch extracted by the pitch extracting means varies within a range of a predetermined musical interval difference, an average of the currently extracted pitch and the previously extracted pitch is calculated and the frequency of the musical tone is defined on the basis of the calculated average which serves as a current pitch. On the other hand, when the currently extracted pitch exceeds the above-mentioned range, the frequency of the musical tone is defined on the basis of the currently extracted pitch. In this manner, an undesirable influence to the sound frequency caused by any unnecessary variations or fluctuations in the pitch is decreased or eliminated, thereby enabling producing of a steady sound frequency.
