Filed: 1985-12-06
Abstract: PURPOSE:To attain information recording with enhanced definition near the end part of a magnetic recording medium without affecting the protection function of the recording medium by recording information at changed levels of a recording signal when the end of the magnetic recording medium is detected. CONSTITUTION:When a tape is supplied from a reel and travels in the direction where the tape is wound by another reel and when a recording failure part at the former reel side passes through a tape end sensor 1, the sensor 1 outputs a signal at 'H'. At that time, the output from an inversion signal generator 8 to a NOR gate 13 is at 'L', and the output of the gate 13 rises at 'H', and a differentiation circuit 16 gives a trigger signal to a one-shot circuit 7 and a voltage generator 5. The output of the generator 8, which is supplied to the UP/DOWN terminal of the generator 5 is at 'L', and the value of a voltage signal is dropping until said output comes to 'H'. Accordingly the level of the recording signal drops to fade out the recording signal.

Title: Image forming device
Inventor: TAKEUCHI AKIHIKO
IPC: G03G21/10
Filed: 1989-10-20
Abstract: PURPOSE:To prevent the occurrence of the flow of a picture caused by soil by applying a bias voltage to a contact electrifying member after an image carrier surface part facing to a cleaning means passes through the position where the contact electrifying member abuts on the image carrier at the time of starting an image carrier. CONSTITUTION:Applying of a bias voltage to an electrifying roller 2a is started after the elapse of DELTAt minutes after the initiation of its rotation caused by the start of the drum 1. DELTAt is set so as to establish the following relation: DELTAt>=l/Vp, where l(nm) is a distance between the cleaning-blade-abutting part E and the electrifying-roller-abutting part D, both of which are in the area of a drum surface part B, and Vp(nm/sec) is the peripheral velocity on the photosensitive drum 1. Therefore, even if rubber, etc., sticks to the drum surface part B when the device stops operation or is in a stand-by condition, or even if developer is taken from the part E abutting on the cleaning blade 11 at the time of starting the drum 1, a bias voltage is applied to the electrifying roller 2a after they pass through the electrifying-roller-abutting part D in the DELTAt time which is the beginning of the prerotation of the drum. Thus, soil of the electrifying roller is prevented, and picture flaw does not occur.
