摘要： A digitally controllable oscillator is provided with a variable-frequency ring oscillator including an odd number of inverting circuits connected together in a ring formation. The oscillator has a pulse circulation device to circulate a pulse signal through the inverters to introduce some delay in the signal. Digital data is produced by a data controller device. A counter is connected to the pulse circulation device and counts the number of times the pulse signal circulates through the inverters. A pulse is generated at a desired frequency based upon the counter's output and the introduced delay. A control device determines which of a plurality of delay signals is applied to the circuit that generates the pulse at the desired frequency.

摘要： A laser printer is provided with a photoreceptor drum for transferring a toner image formed on a peripheral surface thereof to a sheet by rotating. The photoreceptor drum is stored in a process kit. In order to removably secure the process kit, a space is provided in an upper portion of a main body of the laser printer. A pair of bearings is provided in the process kit along a rotation shaft of the photoreceptor drum. Further, a pair of substantially U-shaped guides is provided for removably supporting the respective bearings in a direction substantially perpendicular to the rotation shaft. In this arrangement, since the installation and removal of the process kit can be done from the position above the main body, both the bearings and the guides can be exposed. This permits the respective positions of the bearings and the guides can be easily recognized, thereby ensuring an easy installation and removal of the process kit.

摘要： A digitally controllable oscillator is provided with a variable-frequency ring oscillator comprising an odd number of inverting circuits connected to each other in a ring. The frequency of the output signal of the ring oscillator is determined by a digital input signal specifying the frequency of the output signal of the ring oscillator. The number of times of circulation of a pulse signal through the ring oscillator is counted. A pulse generator generates a pulse signal upon the coincidence of the counted number of times of circulation of the pulse signal through the ring oscillator with a number corresponding to the digital input signal. A series of these operations is repeated to make the pulse generator generate pulse signals successively at a period corresponding to the digital input signal.

摘要： A pulse phase difference encoding circuit provides a digital signal indicating a phase difference between a first input pulse and a second input pulse. The first input pulse is provided to and circulated in a ring signal delay circuit having a plurality of signal delay elements that are connected in series. Intermediate points between the delay elements provide delayed pulses having different delay times. Upon receiving the second input pulse, a selector selects one delay pulse provided by the delay element at which the first input pulse has arrived, and generates a digital positional signal indicating a position of the selected delay element. The number of rounds of circulation of the first input pulse in the ring signal delay circuit is separately counted. According to the number of rounds of circulation of the first pulse and the positional signal, the digital signal indicating the phase difference between the first and second input pulses is formed.

摘要： The process kit is mounted on the apparatus main body from above. By the support frame, the photosensitive drum, main charger and cleaning unit are integrally supported to compose the process kit. At both ends of the support frame, handle members made of flexible resin or metal are provided. The handle members are furnished with fixing pawls for fixing the process kit to the mounting position of the apparatus main body by engaging with the fixing recesses provided at the apparatus main body side. When the process kit is lifted, since the both ends are securely supported and are kept in balance by both hands, the support state of the process kit may be always stable. Whether the process kit is installed securely in the mounting position may be judged easily. That is, any user without professional knowledge can accurately and easily install the process kit.
