摘要： PROBLEM TO BE SOLVED: To provide an image forming device capable of preventing poor contact between a photosensitive belt with a joint and a ground brush to ensure static elimination of negative charge arising in the photoreceptor belt. SOLUTION: In an image forming device for which a photoreceptor belt 1 with a joint 11 is used, two ground brushes 6, 49 are put in contact with the photoreceptor belt 1. Even if poor contact occurs between the photoreceptor belt 1 and the ground brush 6 when the joint 11 passes through the position of one ground brush 6, the other brush 49 is put in contact with the photoreceptor belt 1. In this way, static elimination of negative charge arising in the photoreceptor belt 1 is ensured, thus obtaining a uniform image with no white streaks.

摘要： PROBLEM TO BE SOLVED: To minimize power consumption at the time of setting each automatic recording by supplying power from respective corresponding power supply circuits to a MUSE decoder block in which automatic recording is set and a character multiplex decoder block. SOLUTION: An automatic recording function block is divided into a MUSE automatic recording function block 13 to be a MUSE decoder block and a teletext automatic recording function block 14 being a teletext decoder block. Power supply circuits 15, 16 are prepared so as to independently supply power to respective blocks 13, 14. A control circuit 11 can execute independent power supply control for MUSE automatic recording and teletext automatic recording by independently sending an ON/OFF control signal to the circuit 15 or 16 when a remote controller power supply is OFF in accordance with the independent setting of MUSE automatic recording or teletext automatic recording. Consequently power consumption at the time of setting each automatic recording can be minimized.

摘要： PROBLEM TO BE SOLVED: To provide a TV receiver which can reduce its circuit scale for reduction of its cost and also secures the satisfactory display of a screen via the stable signal processing by preparing a clock selection means that can automatically switch the clock to be supplied to a processor to the clock corresponding to the broadcast system of the input video signals. SOLUTION: A synchronous control circuit 8 synchronously reproduces the input video signals and also decides the system of these video signals to output control signals based on the system decision result. The control signals outputted from the circuit 8 are sent to a CPU 7 and a clock selection circuit 11 respectively. The CPU 7 controls the loading of a program to a programmable arithmetic circuit 3 by the received control signal. The circuit 11 selects a clock signal to be outputted among those clock signals received from a clock generation circuit 9 by the received control signal. Thus, a clock that is adaptive to the system of the video signals can be applied to the signal processing which is carried out by a program.

摘要： PROBLEM TO BE SOLVED: To obtain a good quality image and to improve durability and reliability by disposing a layer-thickness restriction roller parallel to a developing roller in a layer-thickness restriction plane, thereby restricting the thickness of a toner layer on the developing roller, and removing the accumulation of toner by means of rotation. SOLUTION: The layer-thickness restriction roller 29 restricts the thickness of the layer on the developing roller 10, and the accumulation of toner 30 is formed between the layer-thickness restriction roller 29 and developing roller 10 when printing is carried out. The toner 9 stirred and carried by a toner stirring member 8, then supplied to the surface of the developing roller 10, serving as a toner carrier, by a toner supply roller 6, and carried along the surface is subjected to toner-layer-thickness restriction by the layer-thickness restriction roller 29 and, at the same time, frictionally charged and formed into the thin layer on the periphery of the developing roller 10. Thereafter, by a bias voltage applied from a development bias power source 14, the toner 9 is transferred and attached onto a part of the surface of a photoreceptor 1 where an electrostatic latent image is formed, so that the electrostatic latent image is developed.

摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of frictional heat between a thinning layer roller and a developing roller, and obtain a good quality image by changing relative velocity between a toner support roller and a layer thickness regulation roller in response to the change of an environment. SOLUTION: An electrostatic latent image is formed on a photosensitive member uniformly charged by a charger 2. On the other hand, a toner 9 is stirred by a toner stirring member 8, and the toner 9 is supplied to the surface of the developing roller 10 by a toner supply roller 6. The developing roller 10 is pressed by a thinning layer roller 29 fixed by a hold member 30 so as to friction-charge the toner 9 on the surface of the developing roller 10, and simultaneously a thin layer state is formed on the periphery of the developing roller 10. When an environment in which an image forming device is used is in an ordinary temperature/ordinary humidity state, the peripheral velocity of the thinning layer roller 29 is set to 40mm/second, while when the environment is brought into a high temperature/high humidity state, the state is read by a temperature/humidity sensor 31, and the peripheral velocity of the thinning layer roller 29 is lowered to 30mm/second.

摘要： PURPOSE: To totally perform digital processing for the decoding circuit by connecting 1st and 2nd signal processing means directly. CONSTITUTION: A composite video signal to a terminal 1 is converted into a digital signal by an A/D converter circuit 2 synchronously with a clock signal from a 1st clock generating circuit 3. A 1st signal processing circuit 5 converts the digital signal into a luminance signal with a horizontal luminance high frequency signal added thereto and a signal being demodulated vertical time high frequency signal and vertical luminance high frequency signal and a color difference signal and outputs them. A D-D conversion circuit 6 operates its line memory by using a clock signal generated from the circuit 3 for write and using a clock signal synchronously with a horizontal synchronizing signal from a 2nd clock generating circuit 4 for read and converts the signals. A 2nd signal processing circuit 7 conducts processing such as reproduction line interpolation processing for a signal multiplexed onto upper and lower non-picture portion, vertical magnification processing and double speed conversion doubling horizontal frequency, a D/A converter circuit 8 converts the output of the circuit 7 by using a clock signal from the circuit 4 and provides an output of the resulting signals to a luminance terminal 9 and color difference output terminals 10, 11. Thus, the analog processing is eliminated and digital processing is totally used for the decoding circuit.
