A facsimile apparatus includes a main body frame, an operable cover plate for covering at least the front top of the main body frame, a separating roller for separating a document sheet attached to the main body frame and a document feeding mechanism for feeding a document sheet separated by the separating roller. All of the rollers in the document feeding mechanism are attached to the main body frame. Since all rollers of the document feeding mechanism are attached to the main body frame, it is not necessary that the cover plate have high rigidity. Consequently, the weight of the cover plate can be reduced, and the manufacturing cost of the cover plate can be reduced.

A facsimile machine has various detection devices. One of the detection device detects a sheet medium. The detection device includes a reflection type sensor directly mounted on a control board. An actuator is pivotally movably supported in a main frame of the facsimile machine. The actuator has a pivot shaft portion, a first arm and a second arm those extending from the pivot shaft portion. A free end of the first arm is abuttable on the sheet medium. If sheet medium is transferred to a predetermined portion, an edge of the sheet urges the free end to angularly rotate the actuator. A free end of the second arm is provided with a reflection member. The angular movement of the actuator causes the reflection member to be brought into confrontation with the reflection type sensor so as to detect passage of the sheet medium. A regulation member is integrally provided to the reflection member. The regulation member is brought into contact with the control board because of the gravity of the actuator, so that a given distance is provided between the reflection member and the reflection type sensor in the confronting state therebetween. The other sensor device may detects moving phase of a movable member. To this effect, the free end of the first arm is abuttable on the movable member.

The invention provides an ink ribbon cartridge which ensures proper, reliable mounting of an ink ribbon. The ink ribbon cartridge of the invention includes a pair of spools, an ink ribbon including a band-like sheet wound around the pair of spools and provided with a layer of ink formed on one surface thereof, four spindles which have disk-shaped sections at one end and can be placed, for a specific length in both ends of the pair of spools, and a cover covering the pair of spools around which the sheet is wound and having four round holes in which the disk-shaped sections of each of the spindles are loosely fitted. In one of the four ends of the pair of spools, only the other end of a specific one of the four spindles can be inserted for a specific length, and one of the four round holes formed in the cover is formed such that only the disk-shaped section on one side of the specific spindle can be loosely fitted.

A facsimile apparatus includes a light emitting unit disposed downstream in the direction of feed of a document with respect to a normal plane perpendicular to the document surface on a reading line. Outgoing beams for reading travel rearward in a substantially horizontal direction. Incoming beams from the light emitting unit are reflected on the reading line on the document surface and are supplied as the outgoing beams for reading to a light sensing unit. Consequently, it is possible to reduce the height of the front portion of the facsimile apparatus so as to increase a degree of freedom in designing while enhancing reliability in reading the document.

A droplet ejection apparatus includes a plurality of tanks, a plurality of sub-tanks, a replenishment amount detector, a liquid replenisher and a recording head. Each of the plurality of tanks is capable of storing a different kind of basic liquid. The plurality of sub-tanks includes a first sub-tank that includes a mixed liquid of two or more of the different kinds of the basic liquids from the plurality of tanks. The replenishment amount detector detects amount of each of the different kinds of the basic liquids to be transferred to the first sub-tank. The liquid replenisher transfers the basic liquids stored in the tanks into the sub-tanks until a predetermined amount for each of the basic liquids is detected by the replenishment amount detector. The recording head ejects the liquids supplied from the sub-tanks in a form of droplets.

At a predetermined position during the lateral movement of a carriage 10, a gap switching mechanism 30 for switching a gap between a recording head 15 and a recording medium is provided. The recording head 15 is mounted facing downward on the carriage 10. A part close to one side on a lower end of the carriage is slidably and pivotably supported by a guide shaft 11 of a round shaft shape. A switching block member 13 provided with several abutment portions 52 and 53 with different heights, which are positioned so as to be opposed to a slide portion 12a at an upper end of a frame 12 extending in a vertical direction along a back of the carriage. The A switching block member 13 is pivotably supported by the carriage. A first pushing portion 56 is located at a left end of the frame so as to abut against the switching block member 13. A pivotal posture of the first pushing portion is changed due to the abutment to bring the abutment portion 53 into a slide contact relationship with the frame 12, so that a small gap is provided. A second pushing portion 57 is located at a right end of the frame so as to abut against the switching block member 13, a pivotal posture of the first pushing portion is changed according to the abutment to bring the abutment portion 52 into a slide contact relationship with the frame 12, so that a large gap is provided.

An ink jet printer is provided with a carriage, a pair of ink cartridges, an ink jet head, an ink tank, and an ink replenishment device. The pair of ink cartridges stores ink of same color. The carriage alternately supports each the ink cartridge. The ink jet head is supported by the carriage. The ink jet head discharges ink supplied from the ink cartridge currently being supported by the carriage. The ink tank stores the ink of the predetermined color. The ink replenishment device replenishes the ink cartridge currently not being supported by the carriage with the ink from the ink tank.
