A cassette tape player compatible with cassette tapes of different formats incorporates a cassette holder which holds an analog compact cassette and a digital compact cassette in a state they are placed one upon another. The cassette holder includes a cassette holder main body having an analog cassette storage section, a digital cassette storage section, and a second cassette holder member. The second cassette holder member is supported by the cassette holder main body such that it is slightly movable in a moving direction of the cassette holder, and has a slider moving lever for opening the slider of the digital cassette. A cassette tape player with such a cassette holder has separate magnetic heads for analog and digital signals, thereby lengthening the life of the magnetic heads and achieving faithful recording and reproduction.

A magneto-optical recording and reproducing apparatus for recording a recording data on a magneto-optical disk through magnetic field modulation is provided with a magnetic head device for applying a recording magnetic field corresponding to a recording signal current onto the magneto-optical disk. The magnetic head means is composed of coil support means including a hollow tubular portion, coil means provided outside the hollow tubular portion of the coil support means, magnetic head means, provided within the hollow tubular portion of the coil support means so as to be capable of freely sliding, for generating the recording magnetic field by supplying the recording signal current into the coil means, and elastic support means for supporting the magnetic head means so as to place it in a stand-by position where the magnetic head means and the magneto-optical disk do not interfere with one another by a push-up force exerted on the magnetic head means in the direction moving away from the magneto-optical disk. The magnetic head means is moved toward the magneto-optical disk in a direction opposite to the push-up force exerted by the elastic support means so as to come in contact with the magneto-optical disk using an electromagnetic force generated by supplying the recording signal current into the coil means.

Main signals such as music and the like are read while auxiliary signals are simultaneously read from two sectors on a magnetic tape recorded in opposite directions using a tape reader having multiple heads. The read out signals are serially provided from a multiplexer and digitized by an A/D converter. A signal processing unit separates the digitized signals into main signals and auxiliary signals. A microcomputer carries out high speed search procedures using the auxiliary signals.

A cassette-detection device for use in magnetic tape apparatuses which is provided with a first detection means for detecting the difference in thickness between a cartridge and a cassette shell in order to judge which cassette tape is loaded, an analog cassette tape or a digital cassette tape, and a second detection means for detecting the recessed section of the cartridge of an analog cassette tape in order to judge which side is up with respect to the analog cassette tape. In accordance with the above arrangement, by providing a simple structure, judgement is made as to which cassette tape is loaded, an analog cassette tape or a digital cassette tape, and judgement is also made as to which side is up when an analog cassette tape is loaded.

A driving system of a magnetic recording/reproducing apparatus includes a motor, a pulley receiving rotation of the motor, a forward direction rotation body coaxially provided with the pulley, a reverse direction rotation body which always engages with the forward direction rotation body and rotates in the reverse direction, first and second reel stands which engage with respective reels of a cassette tape, and a moving rotation body which engages with the forward direction rotation body and the first reel stand in forward direction rotation, and engages with the reverse direction rotation body and the second reel stand in reverse direction rotation. A forward direction torque generating mechanism is provided between the forward direction rotation body and the moving rotation body and a reverse direction torque generating mechanism is provided between the reverse direction rotation body and the moving rotation body. The forward direction/reverse direction torque generating mechanisms include two friction transmitting members for generating torque suitable to constant speed run and high speed run, respectively. A reflection plate for detecting rotation of the first and second reel stands is fixed to either one of the forward direction rotation body or the reverse direction rotation body. A light emitting light receiving element for detecting rotation of the rotation plate is provided at a position facing to the reflection plate.

A portable electronic language interpreter device comprises an input device for entering a specific word, an abbreviation memory device, and an access device responsive to inputs entered via the input device for addressing the abbreviation memory device to cause retrieval in connection with the specific word. The abbreviation memory device memorizes a great number of words by the usage of abbreviated code information by which a certain number of letters of the words are compressed to allow the minimization of storage capacity. Preferably, the words stored in the memory are related to spelling, meaning, a part of speech, phonetic symbols, varied forms, spelling for a phrase, the meaning for the phrase and the like.

In a speech synthesizer, speech speed is selectable by a switch which selects the number of repetitions of a basic waveform or equivalent parameters thereof.

Speech synthesizer with variable speed of speech

Disclosed is a speech synthesizer integrated circuit as a preferred embodiment of the present invention, which is characterized in that; Using one chip LSI, it implements the fundamental controls for the speech synthesizing operations, for example, and fundamental controls for the key input and display operations (corresponding to the functions usually performed by any of the conventional microprocessors). The preferred embodiment of the present invention has made it possible to realize an extremely useful and versatile speech synthesizer integrated circuit by externally connecting a memory that stores the controlled programs and sound data available for synthesizing the intended speech. By allocating the same addresses to the internal and external memory storage areas, programs can be located at identical memory addresses, thereby increasing system efficiency.

Speech synthesizer integrated circuit

A calculator system with visual and speech outputs uses a single monolithic LSI chip which includes: a single ROM containing program instructions for both system and speech control, as well as data for synthesizing speech; a central controller which calculates both inputted data and program execution data to control the system, and a RAM used by the central controller in manipulating data.

There is disclosed a one-chip speech synthesizer capable of providing synthesized human voices through a new and effective concept of LSI architecture. The synthesizer may execute all of the steps necessary for processing of sample data and enhances the processing speed through a new memory architecture by constructing the one-word length of a control memory (control ROM) longer than the one-word length of a data memory (data ROM). The synthesizer reproduces audible synthesized sounds merely by an added amplifier outside the one-chip LSI semiconductor device without the need to provide a digital-to-analog converter. The LSI device may be used with an expandable external memory as an extension of the data memory (data ROM) whenever a large number of words are to be processed.

A noise-free speech synthesizer is disclosed which interrupts an audible output of synthesized sounds during the period of time where a sound waveform signal is at a relatively low level (amplitude), that is, a voiceless interval, a silent interval or a pitch control interval, wherein a reference level is established for the purpose of controlling pitch. Such low-level cut-off avoids the harsh click of sound cut-off.
