摘要： A sheet guide mechanism is provided with a guide path along which a sheet-like member is guided and which is defined between one and the other guide surfaces. A stationary guide member has a first surface defining the one guide surface, and a movable guide member having a second surface defines the other guide surface, which is shiftable relative to the stationary guide member. Protrusions are formed on one of the first and second surfaces, protruding toward the other of the first and second surfaces by a predetermined distance. A shiftable member is shiftable relative to the stationary guide member between a guide position and a remote position. A spring is provided between the shiftable member and the movable guide member allowing the elastic contact between the protrusions and the other of the first and second surfaces, when the shiftable member is located in the guide position.

摘要： In a sheet warp prevention mechanism adapted to be positioned in an imaging device for forming a visible image, the imaging device includes a pair of rollers adapted to be brought into and out of contact with each other in accordance with a rocking operation of one of the pair of rollers about a predetermined shaft member. The one of the pair of rollers which is arranged to be rotated in a predetermined direction for feeding the continuous sheet has a gear member coaxially provided therewith which is brought into engagement with another gear member coaxially provided with the shaft member about which the roller rotates. A driving source for driving both the one of the pair of rollers and a feeding member for feeding the continuous sheet toward the pair of rollers, and a transmitting mechanism for transmitting the driving force toward the pair of rollers is also included. The sheet warp prevention mechanism include an inhibiting member, provided between the transmitting mechanism and the another gear member, for inhibiting transmission of the rotating force of the one of the pair of rollers to the transmitting mechanism. Thus it becomes possible to prevent the warp of the sheet caused by an undesirable feeding operation.

摘要： This invention relates to a motor velocity control method and storage device for performing loading/unloading control of a head that reads from a storage medium in order to move it away from the storage medium. In order to detect accurate velocity from the counter electromotive voltage of the motor for performing loading/unloading control, the storage device comprises a storage medium 6, head 4, actuator 3, control circuit 19 and ramp 11. Velocity control is performed by using the velocity detected from the counter electromotive voltage of the actuator 3 in the unloading/loading control of moving the head 4 away from the storage medium 6. Moreover, the transient response voltage of the actuator is calculated and the detected voltage is corrected. Furthermore, the velocity offset coefficient for converting the counter electromotive voltage to velocity is calibrated. Also, the velocity correction coefficient for converting the counter electromotive voltage to velocity is calibrated. This makes it possible to obtain accurate velocity from the counter electromotive voltage.
