摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus achieving improvement of efficiency of removing an adhesive matter from a belt by a cleaning roller.
SOLUTION: A printer 1 includes rocking means (pin 84 and pin hole 85) for supporting a pair of backup rollers 54 and 54 in a belt unit 35 in such a state that it can rock relative to the cleaning roller 40. Positional deviation between the backup rollers 54 and 54 and the cleaning roller 40 is absorbed by the rocking means. Since the cleaning roller 40 is brought into press-contact with the belt 38 by sufficient force even when the belt unit 35 and the cleaning unit 41 are attached in posture that they are deviated from a regular position relative to a casing 2, the efficiency of removing the adhesive matter 71 from the belt 38 is improved.

摘要： PROBLEM TO BE SOLVED: To make the structure for guiding a fabric holding frame for holding a textured fabric movably in a prescribed direction compact, and to simplify the structure for guiding the fabric holding frame.
SOLUTION: A movable body 68 for supporting the fabric holding frame for holding the textured fabric is guided by a shuttle shaft 62 stored in a cylinder bed 3 movably forward/backward. As a result, it is not necessary to separately mount a guide member for guiding the movable body 68 forward/backward on the outside of the cylinder bed 3, and therefore, the structure for guiding the movable body 68 forward/backward can be made compact and simplified, so that the embroidery sewing machine can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To switch the position of a thread insertion hook to the engagement position where the hook can be engaged with a thread around a thread hole when the thread is not inserted into the thread hole of a sewing needle for holding the hook at the position, and to simplify the structure of a thread insertion mechanism.
SOLUTION: The thread insertion mechanism 55 has the thread insertion hook 120 movable from an engagement position where the hook is inserted into the thread hole to be engaged with a needle thread 57 located around the thread hole to a retreating position where the hook is drawn out of the thread hole. When the needle thread 57 is not inserted into the thread hole by the thread insertion mechanism 55, the thread insertion hook 120 is switched from the retreating position to the engagement position by a switch mechanism 125 and held there. On the other hand, when a thread cassette in which a thread piece is stored is mounted on a cassette mounting part, the thread insertion hook 120 interlocks with the mounting motion of the thread cassette and is switched to the retreating position by the switch mechanism 125.

摘要： PROBLEM TO BE SOLVED: To efficiently recover developer, such as toner, stuck to a transfer belt. SOLUTION: A crankshaft 25A is positioned in an area displaced toward first holding portions 32A and 33A relative to a falling point P. This prevents developer falling while scraped by a scraping blade 23 from being accumulated on the crankshaft 25A. Accordingly, developer which has fallen in a box body 32 is efficiently moved, and degradation in the efficiency of recovering developer is prevented. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To simplify the structure for cutting a needle thread, to prevent a bobbin thread from being cut at the same time as the needle thread is cut, and to prevent the needle thread from being cut during the sewing.
SOLUTION: The presser foot 46 for pressing a textured fabric comprises a needle hole 50 for a sewing needle 40 to pass during the sewing, a cutter 51 for cutting the needle thread 47 between a thread hole of the sewing needle 40 and the textured fabric, and a guide passage 52 for guiding the needle thread 47 from the needle hole 50 to the cutter 51, having an acute bending part 52a bending acutely in the direction of extension. Accordingly, it is possible to cut the needle thread 47 only with a simple structure, and it is also possible to prevent the needle thread 47 from being cut by the cutter 51 during the sewing.

摘要： PROBLEM TO BE SOLVED: To prevent damage to a needle and tear of a fabric to be processed by prohibiting an arm part from being switched to a retreating position when the needle is exposed from the arm part. SOLUTION: If a signal detected from a thread cassette detecting switch is not a mounting detecting signal, and no thread cassette is mounted on a cassette mounting part (S13, S14:No) when a retreat command key provided on a fingertip key is operated (S10, S11, S12:Yes) in order to switch the arm part to the retreating position from a normal sewing position, a switch prohibiting flag is set (S20), and swinging of the arm part to the retreating position are prohibited. A message saying that no thread cassette is mounted is shown on a liquid crystal display. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To switch an arm part to a retreating position during a sewing process without causing any troubles to a needle and a fabric for processing and making any wrong stitches.
SOLUTION: If sewing is in process and a motor for a sewing machine is driven (S17:Yes) when a fingertip key for a retreat command is operated, the motor of the sewing machine stops driving with the needle located at the high position (S18, S19:YES). If a thread cassette is mounted on a cassette mounting part after a halt of the sewing motion (S20, S21:YES), a switch prohibiting flag is reset (S22), and a carriage is moved to an unlocking position in the back (S25) after moved to the original position (S23, S24:Yes). At the time, a locking mechanism is switched to an unlocking state by the carriage, and the arm part is manually switched to the retreating position by an operator.

摘要： PROBLEM TO BE SOLVED: To provide a sewing machine which never causes an arm part to switch the position during a sewing operation for the sewing machine with the arm part switchable between a sewing position and a retreating position.
SOLUTION: The sewing machine with the arm part switchable between the sewing position and the retreating position above the sewing position is equipped with a locking mechanism 80 for locking the arm part at the sewing position and an unlocking mechanism 90 for unlocking the lock by the locking mechanism 80. The locked state of the arm part by the locking mechanism 80 is never unlocked by the unlocking mechanism 90 during the sewing operation.

摘要： PROBLEM TO BE SOLVED: To prevent damage of a sewing needle and breaking of a textured fabric, and to perform the removal of tangling of threads at a head and the maintenance work.
SOLUTION: When a thread cassette eject key among touch keys is operated (S19:Yes), a removal prohibiting flag for prohibiting the removal of the thread cassette is set (S17) if an arm part is switched to a retreating position (S20:Yes) and the operation of the thread cassette eject key is in a short period of time and in a normal operation mode (S23:No). At the time, a thread cassette eject key signal is canceled and the driving of a thread tension motor is prohibited, so that a thread cassette lock mechanism cannot be switched to the lock release state, and therefore, the thread cassette cannot be removed by an operator.

摘要： PROBLEM TO BE SOLVED: To provide a sewing machine which prohibits vertical movements of a needle supporting member made by a manual operation means without spacing a plurality of gears of a driving force transmitting mechanism when an arm part is rotated upward. SOLUTION: An embroidery machine is equipped with a manually operational hand pulley 19, a rotating shaft 54 rotating with the hand pulley 19, a needle clamp making vertical movements by the rotations of the rotating shaft 54, a ratchet wheel 55 fixed to the rotating shaft 54, a pawl member 56 located in the front of the ratchet wheel 55, a rotating gear 57 rotationally supported by an arm frame 51, and a fixed gear 59 fixed to a first bearing 52b. If the arm part 5 is rotated to a retreated position, the pawl member 56 meshes with the ratchet wheel 55. The engagement prohibits the rotations of the rotating shaft 54 and the vertical movements of the needle clamp by the manual operation means of the hand pulley 19. COPYRIGHT: (C)2004,JPO
