Abstract: The present invention is an electronic apparatus including: an electronic apparatus main body 1; a panel main body that has a first guided component guided by a first guide groove C1 formed in the electronic apparatus main body, and moves in an inclined state with respect to the electronic apparatus main body; and a hold plate 6 that has a second guided portion guided by a second guide groove C2 formed in the electronic apparatus main body, and slidably holds the panel main body. According to the present invention, a mechanism for tilting the panel main body and a mechanism for sliding the panel main body are provided separately from each other, so that the panel main body having an increased weight can be operated smoothly in the inclined state.

Abstract: A tilting apparatus is provided which can make a moving section perform a tilting operation with stability or in which a moving section can exercise its functionality as expected, and an electronic apparatus equipped with the tilting apparatus is provided. In a tilting apparatus, with first and second tilting operations, one side of a first panel holder is angularly displaced with respect to the other side from a reference position. This can prevent the first panel holder from making any extra operation other than the first and second tilting operations with respect to a device body. Unlike any existing technology, in the invention, even when the first and second tilting operations are put into action, a first chassis is not displaced against the device body unless it is desired, e.g., displaced along front, and juts from the device body, thereby favorably leading to the operation with stability.

Abstract: The present invention is directed to a vacuum servo unit, wherein a variable pressure chamber is capable of communicating with the atmosphere through a clearance which is defined between an air valve member slidably mounted on an input member and a seal member provided in a cylindrical member, and wherein the variable pressure chamber is capable of communicating with a constant pressure chamber through a clearance which is defined between a vacuum valve member and a seal portion of a control valve member. Accordingly, when the air is introduced from the clearance between the air valve member and the seal member in the condition where the seal portion of the control valve member is in contact with the vacuum valve member, the control valve member is biased toward the vacuum valve member by the pressure difference between the negative pressure and the atmospheric pressure.

Abstract: An electrophotographic image forming apparatus in which overheating or burning of a heater caused by fabricating units whose specified supply voltages are different from each other is prevented. Power from a main unit is supplied to the heater, which is in a photosensitive drum in a drum unit, for heating the photosensitive drum so as to be maintained at a specified temperature, through a connecter disposed between the main unit and the drum unit. The connecter is comprised of parts which are respectively disposed in different positions, depending on the specified supply voltages. The respective positions of the parts vary, in relation to a reference position, in a direction around the rotation axis of the photosensitive drum which is rotated when the drum unit is installed in the main unit. When the specified supply voltage of the main unit is equal to that of the heater, the parts are fitted to each other, thereby making electrical connection.

Abstract: A vacuum brake booster includes a secured arrangement for securing a flange portion of a control valve element to a cylindrical portion of the power piston so as to prevent relative movement between the flange portion of the control valve element and the power piston. Thereby, the seal surface of the control valve element is not urged toward the valve seat of the power piston by a pressure differential applied to the flange portion. The urging force of a second coil spring arrangement which urges the control valve element to separate from the valve seat in the non-operating condition of the vacuum brake booster is positively decreased without exerting an adverse influence to the control of the braking force of the vacuum brake booster (10). Accordingly, the input load of the vacuum brake booster is decreased and the operational feeling of the braking action is improved.
