摘要： PURPOSE:To provide the processor in which a retrieval speed from a terminal equipment is improved by dividing a picture into plural partial pictures and storing them and transferring the required partial picture with priority to the terminal equipment when the picture having a high resolution such as a document is stored and part of the picture is displayed on a display device with a low resolution. CONSTITUTION:The processor is provided with a picture input section 10, a picture memory 20, coding decoding processing section 30, data storage section 40, input, output control section 45, communication terminal equipment 50, the memory control section 70, partial picture number calculation section 80, and a partial picture number control section 90. Thus, when the number of picture elements of the stored picture is more than the pixel number of a display device and only part of the picture is displayed, the data of the required part are read with priority and transferred, then the retrieval speed is improved and requirements by the user are satisfied.

摘要： PURPOSE:To perform a stable loading action even when a driving load is large by a method wherein a guide-post base is driven by using a second guide-post drive means according to the movement position or the movement speed of a first guide-post base drive means. CONSTITUTION:When a cassette base stand is slid, link gears 242, 250 are turned. When the gear 250 is turned, a link A 252 is turned and driven. However, since a guide van is arranged on a fixed chassis, an impulsive load becomes easily large. As a result, a loading action cannot be performed after that or a magnetic tape is damaged. In order to prevent this, a bent part 2h is formed at a chassis, and the link A 252 is brought into contact with the bent part. Thereby, the link A 252 is turned in a direction opposite to the direction of A, a second drive means can be actuated and guide post bases 246, 258, 259 can be driven.

摘要： PURPOSE:To realize a stable loading action in a magnetic recording and replay apparatus wherein a tape loading action is performed by moving a guide-post base. CONSTITUTION:A sidewall 120e is installed in such a way that it is nearly perpendicular to the sliding face of a guide-post base 246 on a movement regulation member 120 on which the guide-post base 246 is slid. The formation plane of said sidewall is set near the change part of a groove direction or near the part immediately before a part where the guide-post base comes into pressure contact. In addition, the sidewall 120e is constituted of a spring body. It is possible to prevent the posture of the guide-post base from becoming unstable in a loading process by means of the sidewall which has been installed so as to be nearly parallel to the groove direction of the movement regulation member and so as to be nearly perpendicular to the sliding face.

摘要： PURPOSE:To form a sufficient air layer irrespective of the revolution number of a cylinder and to stabilize tape traveling by providing a circular protrusion over all around the outer peripheral face of a rotational cylinder having a magnetic head so as to be brought into contact with a magnetic tape. CONSTITUTION:A rotational cylinder 2 has a little shorter diameter than a fixed cylinder 3, and the circular protrusion 7 of a rib shape is provided over all around the outer peripheral face. When a magnetic tape 6 travels, the rotational cylinder 2 rotates and the recording and reproducing of a signal are executed, the magnetic tape 6 is always brought into contact with the circular protrusion 7. Since the magnetic tape 6 is lifted from a cylinder face by the circular protrusion 7 at a tape inserting side, air sent from the tape inserting side enters between the tape 6 and a cylinder 2 face easily and an air layer is formed. Consequently, since the air layer is formed surely irrespective of the revolution number of the cylinder 2, it can prevent the magnetic tape 6 from sticking to the cylinder 2 face and stable tape traveling can be realized.

摘要： PURPOSE:To simplify a mechanism and to accelerate operating speed by operating an idler incorporating a torque limiter for reproduction only flatly separately from the idler for search to be engaged with a reel base. CONSTITUTION:At the time of performing search at high speed, a motor shaft gear 18 fixed on a motor shaft is engaged with the shaft, and also, the idler 18 operated in such a way that it can be turned around the shaft is engaged with the reel bases 4 and 15, then, the reel bases 4 and 15 are driven. At the time of performing standard reproduction, the idlers 19 and 20 for reproduction only separately from the idler 18 perform turning operation, and engage with the motor shaft gear 17 and the reel bases 4 and 15, which transmits power to the torque of a motor, however, the idlers 19 and 20 are provided with slip mechanisms, thereby, no torque exceeding a prescribed level is transmitted. At the time of performing review where a pinch roller 13 is pressed to a capstan 12 and a tape is fed, the slippage of the idlers 19 and 20 for reproduction only become back torque. Also, when the idlers 19 and 20 for reproduction only are operated, no engagement between the idler 18 for fast search and the reel base is performed. In such a way, it is possible to simplify the mechanism and to accelerate the operating speed.

摘要： PURPOSE:To enable a smooth insertion by eliminating the hanging of a tape cassette at its slanting insertion time by providing a movable projection by an elasticity near the insertion port side of the locking releasing projection part of a tape cassette and having the lock releasing function of the slide plate of the tape cassette on this projection. CONSTITUTION:On a cassette holder 7 a pair of rectangular release projection parts 8 and a pair of movable projections 9 near the insertion port side thereof are provided so as to engage with the sliding groove 5 of a tape cassette 1. In the case of slantly inserting the tape cassette 1 into this cassette holder 7, an engaging projection 6 is moved upwards by the release projecting part 8 and the lock is released, and since the movable projection 9 is terminated at its sliding groove 5 at this time it is moved to the lower part of a figure by a sliding plate 4. Hence, even if the tape cassette 1 is inserted in a slanting state the lock at two places on the sliding plate 4 is simultaneously released and it can surely be inserted.

摘要： PURPOSE:To decrease a peak value of a power noise produced at signal switching without incurring the increase in a chip area by retarding a switching timing of plural output signals by a prescribed time at each several signal line bundles. CONSTITUTION:In case of, e.g., a voice recognition CMOSLSI circuit, 20 data lines D are divided into D1 in 6-bit and D2, D3 in 7-bit, the D1 is latched to a memory address register MAR1 in the timing of CK, the D2 is latched to an MAR2 by using a clock CK2 delayed by a delay time of the two stages of inverters INV than the time of the CK, and the D3 is latched in an MAR3 by using a clock CK3 delayed by the delay time of two stages of the INV than the time of the CK2. Thus, six lines are switched in the timing of the CK, seven lines are switched in the timing of the CK2 and seven lines are switched sequentially in the timing of the CK3 in the output circuit. Thus, the peak current produced in the output circuit and power supply is decreased at the switching of data in 20-bit.

摘要： PURPOSE:To enable to generate graphs remarkably different in slops in a good manner, by selcting the means designating the summing point according to primary increment and by altering the summing point of the secondary increment. CONSTITUTION:The operation section performs integrating operation and stores the integrating value, residual and the ternary increment to the memory respectively. Further, the register DX stores the primary increment, and the selector SLC1 selects the memory content fed to the terminals B1...B3 according to the content of the register DX and the output of the memory storing the information determining the summing point of the secondary increment, feeds them to the secondary addition circuit SDY, feeds the output of the circuit SDY to the parallel addition circuit SIGMA1 and outputs them with the addition and subtraction with the parallel adder SIGMA2. In this case, the control of the addition and subtraction of the adder SIGMA2 is made with the determination circuit X. If the output of the register DX is 01, addition is made, if 10, then subtraction, and if 00, the content of the buffer register BR2 is outputted, allowing to generate graphs remarkably different in slopes in a good manner.
