摘要:
An image forming apparatus, which includes a photoreceptor having a substrate whose surface having been subjected to a surface processing with a cutting tool, and a photosensitive layer formed on the substrate; an exposure device for exposing an image on the photoreceptor to form a latent image, having a light source for emitting a light beam, and carrying out exposure in a manner of dot arrangement through a main scanning by the deflection of the light beam and a sub-scanning by a movement of the photoreceptor; a developing device; and a transfer device. The apparatus is characterized in that the exposure device carries out scanning exposure with a spatial frequency of dot arrangement pitch of not less than 4 dots/mm in the main scanning direction, and surface roughness Rz of the substrate in the main scanning direction is not greater than 1.5 &mgr;m.

An image-forming apparatus is provided which primarily transfers a toner image onto an intermediate transfer member, and then secondarily transfers the toner image from the intermediate transfer member onto a transfer material, wherein a controller controls the process so that when the image forming apparatus stops, a toner image pattern &agr; formed on a non-image area of a photoconductive member is preventing from causing image problems.
摘要:
An image forming apparatus is provided which includes photoreceptors, around which are a charging section, an exposing section and a developing section, for forming a toner image. The image forming apparatus also includes a rotatable intermediate transfer member, first transfer sections, a second transfer section, having a transfer roller, for transferring the toner image from the intermediate transfer member to a transfer material, and a controller to control the image forming condition based on a detected density of an image pattern a formed on a non-image area of the photoreceptor. The controller releases a pressure contact of the transfer roller of the second transfer section, before the image pattern &agr; arrives at the second transfer section and starts a next print cycle after again making the pressure contact.

A female terminal fitting (20) has a main body (21) in the form of a rectangular tube. An elastic contact piece (27) is formed by folding back an extending part of a vertical wall (26) on the main body (21). An accommodation space (28) is defined in the main body (21) upward from the elastic contact piece (27). A male terminal fitting (10) can be inserted into the accommodation space (28) and displaced downward to bring the male terminal fitting (10) into contact with the elastic contact piece (27). Restricting projections (37, 38) project from upper and lower sides of the elastic contact piece (27) and are held in contact with a receiving portion (36) that bulges out from the vertical wall (26). The restricting projections (37, 38) prevent the elastic contact piece (27) from being deformed in response to forces exerted by the male terminal fitting (10).

A terminal is provided for stable mounting at a predetermined position of the leading end of a coaxial cable. The terminal 1 has rear side formed with a barrel 7 to be crimped into connection with the coaxial cable 2. A cover 11 is integrally provided before the barrel 7 for covering an exposed section of a core 3 of the coaxial cable 2. An embossed positioning portion 12 is formed between the barrel 7 and the cover 11. When the terminal 1 is mounted on a stripped end of the cable 2, the front end of a folded section 5A contacts a locking edge 12C of the positioning portion 12, thereby restricting any further insertion of the coaxial cable 2. Thus, the terminal 1 can be automatically positioned on the coaxial cable 2 with respect to the longitudinal direction of the coaxial cable 2.

An inner terminal 11 is accommodated in an accommodating portion 20 of an outer terminal 12 via a dielectric element 13. A core 2 of a shielded cable 1 is fastened to an inner fastening portion 18 of the inner terminal 11 outside the outer terminal 12, and then the inner terminal 11 is inserted into the dielectric element 13. A braided wire 4 is folded back around an end of a sheath 5, and an outer fastening portion 22 of the outer terminal 12 is fastened to a folded portion 4A thereof. A covering wall portion 21 in which only the upper surface is open is provided between the accommodating portion 20 and the outer fastening portion 22 of the outer terminal 12, and the inner fastening portion 18 is located in the covering wall portion 21. Upon the completion of crimping, the shielding terminal 10 is fixed by inserting the cover 14 into the opening 21A of the covering wall portion 21 and thereby elastically holding the outer fastening portion 22 by holding pieces 39 of a clip portion 37 from opposite lateral sides. As a result, the core 2 has its fastened portion and a portion near it covered on four sides by conductive members.

A cover 20 is attached to connector body 10, and has a connecting and supporting member 30 engageable with a receiving member 16. Once engaged the member 30 cannot be removed. The connecting and supporting member 30 can be released only by breaking a breakable member 32. Consequently the connection of the cover 20 with the connector body 10 is maintained with certainty. In a preferred embodiment a part of the breakable member 31 is retained after breaking, this giving evidence that the cover has been removed.

In a ring trip circuit, a trip detecting circuit includes a low pass filter connected to opposite ends of a first resistor detecting an AC ringing signal, a diode bridge connected to an output of the low pass filter, a first series circuit connected to an output of the diode bridge and composed of a Zener diode and a light emitting diode of a first photocoupler, so that a phototransistor of the first photocoupler outputs a trip detection signal to a circuit which can be driven with a different power supply. A zero-crossing point detecting circuit has a second series circuit connected to the opposite ends of the first resistor and composed of a second resistor, a second Zener diode and a light emitting diode of a second photocoupler, so that a phototransistor of the second photocoupler outputs a zero-crossing point detection signal to a circuit which can be driven with a different power supply. A ringing signal supplying relay control circuit receives the trip detection signal and the zero-crossing point detection signal, for generating a switching signal at a zero-crossing point of the AC ringing signal.

A lever-operated connector includes a pair of connector housings displaced toward each other to be connected together by rotationally moving a lever form an open position to connected position, a cam follower portion provided on one connector housing, the lever rotatably mounted on the other connector housing, a lever lock portion, and a return spring. The lock portion has a retaining pawl provided on the one connector and a retained portion provided on the lever. The cam portion has a play region for allowing the lever to return a predetermined angle from the connected position toward the open position. A surface on which the retained portion is engaged with the retaining pawl is inclined in such a direction as to hamper retraction of the retaining pawl. Furthermore, the lever is automatically brought into a upstanding condition by the return spring.

A lever type connector, comprising: a pair of a first connector and a second connector to be connected with each other, in which a lever is rotatably supported by a pair of supporting shafts on the first connector; a pair of guide pins which engage each of a pair of guide grooves formed on the lever project from the second connector; and the lever is rotated to move the second connector into the first connector so as to connect the first and second connectors with each other or move the second connector away from the first connector so as to disconnect the first and second connectors from each other due to the engagement between the guide pins and the guide grooves, thereby to reduce the horizontal distance between the supporting shaft and an end of the lever, thus making the lever compact.
