摘要： A recording medium discharging apparatus which can be mounted on top of the image forming apparatus includes a plurality of recording medium storers and a locking mechanism for locking the discharging apparatus to the image forming apparatus when the discharging apparatus is mounted on the image forming apparatus. The locking mechanism includes a release lever for unlocking the discharging apparatus by being manipulated to shift in the same direction as the discharging apparatus moves away from the image forming apparatus to be dismounted from it. The locking mechanism prevents the discharging apparatus from falling off the image forming apparatus even if external force is applied to the discharging apparatus mounted on the image forming apparatus. The release lever for unlocking the discharging apparatus makes it easy to dismount the discharging apparatus from the image forming apparatus.

摘要： A paper sheet discharge apparatus comprises a transport roller that transports paper sheets discharged from an image-forming apparatus, a plurality of switching flappers that guide the paper sheets to desired bins, and a plurality of delivery rollers that discharge the paper sheets via the switching flappers to the bins. The paper sheets are reliably stored in the desired bins without decreasing their transport speed by the aid of the transport roller, the switching flappers, and the delivery rollers. The power from a motor is transmitted only to the delivery rollers which are used to discharge the paper sheets while being interlocked with the specified switching flapper.

摘要： A recording medium discharge apparatus includes bins for storing sheets of paper therein. The apparatus also includes level sensors for each detecting one of the bins having been filled with paper sheets. Each sensor consists of a light emitter and a light receiver, which are positioned on both sides of the associated bin. The emitter and the receiver are aligned on a line extending across the direction in which paper sheets can be discharged. This prevents paper sheets from coming into direct contact with the sensors. Even if paper sheets discharged into each bin are once taken out and then returned to it, the returned sheets do not come in contact with the associated sensor. It is therefore possible to keep the discharge of paper sheets in good condition.
摘要翻译：记录介质排出装置包括用于在其中存放纸张的箱体。该装置还包括用于每个检测已经填充有纸张的一个箱体的液位传感器。每个传感器由光发射器和光接收器组成，它们位于相关仓的两侧。发射器和接收器在延伸穿过可以排出纸张的方向的线上对齐。这样可防止纸张与传感器直接接触。即使排出到每个箱子中的纸张一旦被取出然后返回到其中，返回的纸张也不会与相关联的传感器接触。因此可以保持纸张的排出状况良好。

摘要： An image forming apparatus in which probability of sheet jamming is reduced and jammed sheet can be easily removed. The apparatus is provided with a guide plate, a movable guide plate defining a sheet feed passage therebetween, and a first sheet feed roller. A detachable sheet cassette is provided for attachment to a main body portion of the apparatus. In the sheet cassette, are provided a second sheet feed roller and a leaf spring which urges the second sheet feed roller toward the first sheet feed roller when the sheet cassette is attached to the main body portion. The sheet feed passage is opened by pivotal movement of the movable guide plate when the sheet cassette is detached from the main body portion, to thereby facilitate removal of the jamming sheet from the sheet feed passage.

摘要： A sheet feed cassette capable of preventing a sheet of a sheet stack from diagonal feeding when the sheet is delivered out of the cassette. The sheet feed cassette has sheet guides at lateral sides thereof whose inner surfaces serve as sheet guide surfaces. In the sheet guide, box like portions are provided. In the box-like portions, sub-guides are provided protrudable from upper ends of the sheet guides. The sub-guides have sub-guide surfaces flush with the guide surfaces of the sheet guides. Each lateral side edge of the sheet is abuttable with each of the sub-guide surfaces if the sheet is positioned above the upper ends of the sheet guides for guiding the sheet in a sheet feeding direction. Thus, the diagonal travel of the sheet can be obviated by the sub-guides.
摘要翻译：一种片材进给盒，当纸张被从纸盒中传出时，能够防止纸张堆叠的纸张对角线进给。供纸盒在其侧面具有片材引导件，其内表面用作片材引导表面。在片材引导件中，提供盒状部分。在盒状部分中，从导板的上端突出设置副导向件。副导向件具有与导板的引导表面齐平的副导向表面。如果片材位于片材引导件的上端上方，片材的每个横向侧边缘可与每个子导向面邻接，以便在片材进给方向上引导片材。因此，片材的对角线移动可以被子导轨消除。

摘要： In a printing apparatus wherein a reversible ribbon cassette is detachably installed, provided are means for indicating which side of the ribbon cassette is the side facing upward and means for detecting whether the side of the ribbon cassette attempted to be reloaded after once removed is the side facing upward or not based upon the indicating means. Thereby, misloading with the not-on-use side of ribbon cassette turned up is prevented and accordingly possibilities of blurred printing caused by use of already used area of the ribbon and/or of waste of the ribbon with remaining non-used portion thereon can be avoided. Further, even if the ribbon cassette installed in the apparatus is a multi-use-type one, the possibility of the printing quality being uneven due to the difference in number of times of use in places on the ribbon can also be prevented.

摘要： An image reading device for reading images on a recording medium, including a support member for supporting the recording medium, an image-reading unit having a reading portion for reading the images on the recording medium, and a movable guide member. The reading portion is disposed near the support member so that the reading portion is movable between a reading position for reading the images, and, and an inoperative position. The movable guide member is disposed near the support member so that the guide member is movable between a retracted position in which the guide member does not interfere with the reading portion in the reading position, and a guiding position for directing the recording medium along a part of a predetermined path along which the recording medium is inserted. The movable guide member is held in the retracted and guiding positions while the reading portion is placed in the reading and inoperative positions, respectively.

摘要： A fixing unit for an image forming device such as a laser printer includes a heat roller and a heating member driving unit to drive the heat roller. The heat roller includes a hollow cylindrical tube and a resistance heating member to selectively heat portions of the tube along the axial length thereof. The resistance heating member includes an insulating layer and a conductive layer. The conductive layer is provided with a plurality of resistance heating patterns arranged along the axial length of the tube and connected to a plurality of electrode portions. The connections between the resistance heating patterns and the electrode portions are arranged such that applying a voltage across selected electrode portions causes selected resistance patterns to generate heat and thus, selectively heat a portion of the tube along the axial length thereof.

摘要： A thermal printer for printing with a print head moved relative to and in contact with a recording medium, supported by a platen. The print head has a plurality of printing elements arranged on its front surface, in a direction intersecting a print line. The print head is supported by a support structure movably between printing and retracted positions. The support structure provides, at least when placed in the printing position, a wedge-shaped clearance between the front surface of the print head, and a plane tangent to the bearing surface of the platen. The wedge-shaped clearance increases with a distance from the printing elements in a direction parallel to the print line. The print head further has a head driver secured on its front surface such that the head driver is positioned within said wedge-shaped clearance. The head driver is electrically connected to the printing elements, for controlling energization of the printing elements.
