Patent JP-H0446361-A (JP)
Title: Image forming device
Inventor: SASAKI YUKIO
IPC: G03G15/05
Filed: 1990-06-14
Abstract: PURPOSE:To obtain a sharp toner image on a photosensitive body by providing a developer stagnating part with a belt-like recovering electrode, and also providing the recovering electrode with a second voltage applying means which applies the reversed polarity voltage to that applied by the use of a first voltage applying means. CONSTITUTION:The part of the developer pool 10 is so provided with the belt- like recovering electrode 21 that it is insulated from a sleeve 2b. The reversed polarity voltage to that applied by the first voltage applying means 6 is applied by the second voltage applying means 7. The electrode 21 is insulated from the sleeve 2b together with a recording electrode 5 by the use of an insulating film 22. The width of the recovering electrode 21 determines the influence range of a background-toner recovering voltage (which is applied by the second voltage applying means 7). Therefore, even if a contact-distance between the developer pool 10 and the photosensitive body 1 is changed, the influence range of the recovering voltage does not change. Thus, regardless of the change in the contact distance between the developer pool 10 and the photoconductive body 1, the influence range of the recovering voltage can be made constant, and the sharp toner image can be steadily formed on the photosensitive body 1.

Abstract: PROBLEM TO BE SOLVED: To obtain an inspection apparatus which prevents the connection defect or the damage of a burn-in board due to an irregularity in the height of a socket by a method wherein a contact-force measuring means is installed and the contact force of a pin at a checker probe with a contact pin at the socket is set arbitrarily. SOLUTION: A chuck 31 is installed vertically at a chuck mounting part which is installed on the front side of a driving head 8, and a checker probe 9 is chucked. A plurality of pins 12 are arranged and installed at the probe 9 so as to correspond to contact pins 10a at a socket 10. At this time, a gap is formed on the rear surface of the chuck mounting part, a pressure sensor 32 at a contact-force measuring means is fixed, and its cable is connected to a control device. When the probe 9 comes into contact with the socket 10, the control device stops the movement to the lower direction in the Z-axis of the head 8 when data obtained by A/D-converting the output voltage of the sensor 32 reaches a preset definite value. The definite value is the value of the optimum contact force of the probe 9 with the socket 10.  Thereby, the pins 12 and the contact pins 10a can be touched soft at a definite contact force.
