Abstract:
PURPOSE: To prevent a magnetic tape from being tightly stretched with excessively strong tension by constituting a recording and reproducing device so that an electrical tension regulator can control the tension of the magnetic tape on the downstream side of a capstan. CONSTITUTION: A control circuit 60 is constituted of, for example, a one-chip type microcomputer, provided with, for example, a four-bit parallel processing arithmetic processor (CPU), storage device (RAM) in which a prescribed program is written, in advance, input-output interface which controls the input and output of signals, etc., and performs prescribed arithmetic processing based on signals inputted from A/D converters 57 and 58. Since the circuit 60 adjusts the voltage applied across a reel motor 20 by controlling the output of the circuit 60 based on the processed results, the tension of a magnetic tape is maintained at a fixed value on the downstream side of a capstan 13.
Abstract:
PURPOSE: To perform fast forward(FF) and rewind(REW) of a tape without any possibility of damaging the tape and only by a tape guide without winding the tape around a rotary drum even when excessive tension is applied to a tape guide during loading. CONSTITUTION: A control pin 38 is provided in a tension arm 30 and a stopper arm 40 is also provided so as to be relatively rotated with the tension arm 30. The stopper arm 40 is provided with an elastic body 44 positioned in the pulling out side of the control pin in its moving direction and a stopper wall oppositely placed so as to hold the control pin 30 while keeping a prescribed interval with the elastic body 44. By restricting the moving range of the control pin 30 by the elastic body 44 and the stopper wall, the rotating range of the tension arm 30 is controlled by the stopper arm 40.
Abstract:
PURPOSE:To evade hindrance to a tape loading operation by releasing turning restriction on a supply side tape reel and drawing out a tape from the supply side in place of a take-up side tape reel. CONSTITUTION:When the beginning of the tape T drawn out of the take-up side tape reel 2 is detected by a photodetector part 22, this drawing operation is stopped. Then, when the beginning of the tape is not detected, tape loading is completed, and turning regulation of a reel base 17 is released to make the supply side tape reel 1 turnable, and a pinch roller 15 is moved to a capstan 13 to hold the tape T between them. Then, the tape T is traveled via a rotary head cylinder 12 from the reel 1 to 2 or the reel 2 to 1. Then, when the tape is directed from the reel 1 to 2, a recording operation, a reproducing operation and a fast forward reproducing operation, etc., are performed, and when the tape is directed from the reel 2 to 1, a rewinding reproducing operation, etc., are performed. Upon completion of these operations, the tape T is taken up in synchronization with movement of movable guide posts G1-G8 to their unloading positions after regulating turning of the reel base 17.
Abstract:
PURPOSE:To miniaturize the device for a normalized tape cassette used for the device such as a VTR, etc., by expanding the mouse part and putting the mechanism such as a rotary head drum of a loading device into the space. CONSTITUTION:The depth of the mouse part of tape cassette is expanded by forming tape reels 1, 2 small in diameter. Thereby, the mechanism of the loading devices such as the rotary head drum, tape guide, etc., can be out deeply into the mouse part 6 inside to make the occupied space small, and also the mechanism is simplified by reducing the movement of the mechanism.
Abstract:
PURPOSE:To reduce the size especially in thickness of a device of a rotary head drum and its peripheral mechanism by positioning inlet and outlet tape guides under their loading state to be distributed in the opposite direction to each other from the tape center of a cassette. CONSTITUTION:The tape of the tape cassette 2 is wound, being guided by the tape inlet guide 4 and tape outlet guide 5 to the rotary head drum 3 at a winding angle required for the tape to be pulled out. The inlet and outlet guides 4 and 5 under their loading state are disposed in the opposite direction to each other and also in their equal distances h1 and h2 respectively to the tape center X-X' of the cassette. Consequently, the drum 3 and tape guides, etc., can be disposed fully in the height of a case without making a dead space, enabling a device to be of a small tape and of a thin type as well.
Abstract:
PURPOSE:To attain thin profile to the entire device by forming a slot to the outer circumference of a supply reel base, winding a strip such as a wire to the slot to change the tape tension of a tape run from the supply reel base to a rotary head drum thereby making the thickness of the supply reel base in the height (vertical) direction. CONSTITUTION:A slot 14 whose cross section is U-shaped is formed into an annular shape to the upper outer circumferential face 3c of a gear 3b of a supply reel base 3, and a very thin wire 15 as a strip is wound onto the slot 14. Both ends 15a, 15b of the wire 15 are caulked in a ring to a fastening plate 16. Since the very thin wire 15 is used in place of a conventional wide band brake, since it is not required to provide a contact face of a band brake having a thick thickness to the upper outer circumferential face 3c of the gear 3b of the supply reel base 3, the thickness H in the direction of height of the supply reel base 3 is made thin. Thus, the thin profile for the entire device is attained.
Abstract:
PURPOSE:To surely position the inserting and taking off positions of a cassette by abutting the guide part of the cover part of a cassette holder against a pressing ball at two positions. CONSTITUTION:When a cassette 1 is loaded and subjected to a cover closing operation, a slider 17 slides the cassette to a rear part with the energizing of a spring 57. When the cover is opened by pushing an ejection button, the locking part 37a of a circular arcuate guide piece 35 and the ball 40 of a pressing member 38 are abutted and stop once in a temporarily releasing state and the dropping of the cassette is prevented by a dropping prevention piece 20. By opening the cover with a hand further, the ball 40 runs over a stepping part 37, abutting against the locking part 37b and the turning in the cover closing direction is regulated. Consequently the positioning of the insertion and taking off of the cassette is ensured by abutting the ball 40 against locking part 37 and the dropping of the cassette caused by a careless ejection operation can be prevented.

Then, from among the detected skin temperature image portions, skin temperature image portions where motions are observed are defined as detection target images, and an operation input is recognized based on states of the motions of the detection target images.
Abstract:
PROBLEM TO BE SOLVED: To provide a technology of an input device or the like for preventing operation unintended by a user. SOLUTION: When the user starts pressing of a button 11 provided in the input device 1, input of an operation signal is started (Fig.1(A)). When the input of the operation signal is started, an MPU (Micro Processing Unit) 19 generates a determination command (Fig.10(B)). Next, the MPU 19 calculates a speed value based on a detection signal from a sensor unit 17, and calculates a sensitivity change value based on the speed value. The MPU 19 transmits information of the sensitivity change value to a controller 40 within a sensitivity change period (Fig.10(C)). Thereby, because movement of a pointer 2 can be restrained within the sensitivity change period after the generation of the determination command, the input device allows the prevention of the operation unintended by the user such as non-execution of processing intended by the user on a screen 3 when the determination command is generated. The processing can be also applied to a gesture operation type input device. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an input device, a control device, a control system and a control method for easily moving UI to a prescribed direction. SOLUTION: An MPU 19 of an input device 1 multiplies a yaw angular velocity value ω ψ and a roll angular velocity ω ϕ respectively by movement coefficients α and β expressed by prescribed rates. An MPU 19 calculates the composite angular velocity value ω γ of two angular velocity values ω ψ ' and ω ϕ ' acquired by multiplying the angular velocities ω ψ and ω ϕ by the movement coefficients α and β (step 704). As the calculation expression of composition, for example, ω γ =ω ψ '+ω ϕ '(=αω ψ +βω ϕ ). Thus, it is possible for the user to control the movement of a UI in a first axial direction by either rotating an input device around a Z' axis and moving the input device to an X' axis direction.
