摘要： PURPOSE:To simplify a mode switch and reduce the size of the mode switch by a method wherein the position of one mode is detected by the mode switch and an each mode is set by driving a driving source for a required time from the first detected position. CONSTITUTION:When loading is started, a cam gear 10 is driven to rotate by a loading motor 5. With this rotation, a brush 103 touching the terminal 102 of a mode switch 9 is turned with the cam gear 10 and is separated from the terminal 102. The time required for the cam gear 10 to rotate from a mode before the loading is started to respective modes is measured beforehand and stored in a microcomputer 104. When an apparatus receives, for instance, a signal giving instruction to enter a recording mode, the microcomputer 104 receives the signal and a driving IC 105 drives the loading motor 5 for the required time stored beforehand. With this operation, the cam gear 10 rotates a required angle and the apparatus is put into a recording mode state.

摘要： PROBLEM TO BE SOLVED: To provide a technology which realizes an inexpensive constitution, without degrading its performance and affecting its size due to the reduction in vibrations and noises when an optical pickup is moved, in an optical disk device.
SOLUTION: An optical pickup driving mechanism member is constituted so that an elastic body having elastic performance is made to intervene, attach, and hold between the optical pickup and a fastening and holding member. This allows the transformation of force to be cut by an independent movement from the optical pickup as the driving mechanism member, and impulsive vibrations and impulsive noises generated in a guide receiving section of the optical pickup to be reduced, without converting the inertial force generated when the optical pickup is moved, into the torque.

摘要： PROBLEM TO BE SOLVED: To dynamically determine an image of an appropriate format for the terminal in a reception terminal which is not connected to a server managing image contents, and to overcome a difficulty in expanding of later decision processing since information used for an appropriate contents selection is always fixed items. SOLUTION: When an image is firstly watched and listened, appropriate image formats for all reception terminals owned by users are preliminarily obtained and recorded in a memory card. The reception terminal preferentially reads a decision result from the memory card. In order to make dynamic decision processing possible, a tag type information storing format is used for an information description, and a plug-in decision processing is added to the decision processing.

摘要： PURPOSE:To reduce the plane area of a fixed chassis and to make an apparatus small-sized by a method wherein a guide plate to which a gear shaft has been coupled so as to be passed is arranged between a cassette base stand and a loading gear. CONSTITUTION:The tape-drawing-out mechanism of a magnetic recording and replay apparatus is provided with the following: a fixed chassis 1; a cassette base stand 2 which has been held so as to be capable of being slid; a drawer roller which draws out a magnetic tape during the sliding action of the base stand 2; and a guide plate 121 which drives the drawer roller. In the tape- drawing-out mechanism, loading gears 104, 106, 107 which transmit the rotation- driving force of a loading motor 103 to the movement or the like of the cassette base stand 2 are mounted on gear shafts 1d, 1f, 1g on the chassis 1 so as to be turned freely. In order to prevent the gears 104, 106, 107 from coming off to a thrust direction, the guide plate 121 to which the gear shafts 1d, 1f, 1g have been coupled so as to be passed is arranged between the base stand 2 and the gears 104, 106, 107.

摘要： PURPOSE:To instantaneously apply a braking force on a reel base without needing a quick braking mechanism by rotatably driving an idler arm on a supply-side reel base and engaging an idler gear and a supply-side reel when the device is moved from a driving state to a stop state. CONSTITUTION:On a REW operation an idler gear 143 is engaged with a winding-side reel by a neutral position deciding member 280 and an idler arm 144 is always pressed in the direction of encroaching in a winding side reel base 201. When a STOP command is added, the rotation of a capstan motor 102 is changed from a supplying direction to a winding direction. In accordance with this change of a rotary direction, the arm 144 is rotated in the supplying direction, the gear 143 is disengaged with the gear section 201a of the reel base 201 and engaged with the gear section 202a of a supply-side reel base 202. At this time, the supply-side reel is rotated in the winding direction by inertia. Thus, the number of components is reduced, the device is miniaturized and further, a highly reliable braking mechanism is realized.

摘要： PURPOSE:To perform the voice quality conversion of user's choice in real time by providing a voice quality converting means which outputs a decoded voice waveform while thinning or interpolating it at every sampling interval. CONSTITUTION:A control circuit MCU reads an encoded voice from a first memory M1 with one frame as the unit to transfer it to a second memory M2 and sets thinning or interpolation and its sampling interval. One-frame components of the encoded voice transferred to the second memory M2 are decoded to a voice waveform by a decoding part DEC and are stored in a third memory M3. A voice quality converting part VCC thins or interpolates the voice waveform read out from the third memory M3 in accordance with the sampling interval set by the control circuit MCU to change the pitch of the voice, thereby converting the voice quality. Thus, voice quality conversion of user's choice is performed in real time.
