Title: Image recording device
Inventor: KAGAYAMA SHIGERU
IPC: G03G15/05
Filed: 1990-10-25
Abstract: PURPOSE:To reduce cost and make stable recording with simplified construction by selectively charging toner directly from an electron source in which vacuum tube, etc., is used. CONSTITUTION:A toner supply unit 40 rotates a roller 42 while moving to distribute toner on a front panel of a scanning electron source 10. The charging operation on toner is then started and the toner 41 charged selectively according to image is arranged. Next, a sheet 30 is transferred into a device and, when it reaches at over the scanning electron source 10, a transfer unit 50 is operated to move over the sheet 30 with the transfer roller 52 pressed against the sheet. Since positive voltage is applied to the roller 52, the toner on the front panel charged negative is attracted electrostatically toward the roller 52 and the toner is transferred electrostatically onto the sheet 30. The transferred sheet 30 enters a fixing unit 60 and the toner on the sheet 30 is melted and fixed. Thus the toner is charged directly and stablly to simplify the mechanism of the device and to reduce cost.

IPC: G11B20/12
Filed: 1988-11-18
Abstract: PURPOSE:To easily detect the start point of effective data by defining a frame synchronizing pattern, which is arranged in the start point part of the effective data, as a data pattern to be different from the synchronizing pattern which is inserted to the other part in the effective data. CONSTITUTION:For a frame synchronizing signal to show the start point of effective data N in respective tracks 2, a synchronizing pattern A is arranged. Among the effective data N in the other part, a synchronizing pattern B to be composed of the data pattern, which is different from the synchronizing pattern A, is arranged as the synchronizing signal respectively. Accordingly, at the time of reproducing, the synchronizing patterns A and B are detected and a time point, in which the frame synchronizing pattern A is periodically detected, can be regarded as the start point of the effective data N in the track 2. Thus, without using an external referring signal to roughly give start point information, the start point of the effective data can easily be detected.

Title: Image forming apparatus
Inventor: TANAAMI HIDEYUKI
IPC: G03G21/14
Filed: 1994-11-25
Abstract: PURPOSE: To always achieve proper feed control regardless of the size of a recording medium by detecting the rotation difference of a feed means to accurately detect that the recording medium is passed through an upstream feed means and changing over the feed speed of a downstream feed means from high speed rotation to low speed rotation. CONSTITUTION: When the feed of recording paper P is started, since the recording paper P is held only by a lower feed roller pair 3 at first, a speed changeover clutch 6 is turned ON and an upper feed roller pair 4 is driven at a high speed. When the rear end of the recording paper P comes out of the lower feed roller pair 3, the recording paper P is fed only by the upper feed roller pair 4 held to a high speed state and, therefore, an energizing roller 8b is rotated at a high speed. At this time, a difference is generated between the respective output signals of the encoder 9 for the energizing roller and the encoder 10 for the feed rollers. When the output difference is not detected, the energizing roller 8b is continuously rotated at a high speed and, when the output difference is detected, the speed changeover clutch 6 is turned OFF.

Filed: 1986-12-08
Abstract: PURPOSE:To simplify the structure of a steering control means by steering a front wheel based on the light receiving position information on one of paired front and rear light sensors and steering the rear wheel by the light receiving position information on the other light sensor. CONSTITUTION:In case a vehicle V is shifted to the left against the projecting direction of a guide beam light A, both front and rear wheels 1F and 1R are steered in the shifted light receiving positions against the reference positions of light sensors S1 and S2 corresponding to both wheels. Thus, the vehicle V is automatically changed by a steering system and the direction of the vehicle V is corrected. While the light receiving positions of sensors S1 and S2 are shifted to the right where both receiving positions are set in the same direction to their reference positions. In such a case, both wheels 1F and 1R are changed in the same direction in response to the shift directions of said light receiving positions. Thus, the vehicle V is automatically shifted in parallel by a steering system and the width directional position of the vehicle V is corrected. In such a way, the structure of a steering control means is simplified.
