The present invention discloses medical equipment and an endoscope apparatus. The medical equipment includes an optical connector that detachably connects a plug to a receptacle provided in an equipment main body to optically connect a plug-side optical fiber fixed to the plug and a receptacle-side optical fiber fixed to the receptacle. The plug and the receptacle have plural engagement pairs each having a protrusion that protrudes in an insertion direction of the plug and an engagement part that is adapted to be engaged with the protrusion. Engagement beginning positions of the engagement pairs where the protrusions and the engagement parts begin to engage are different along the insertion direction. Each engagement pair has a narrower engagement gap between the protrusion and the engagement part than that between the protrusion and the engagement part of any pair which begin to engage earlier as the plug is inserted than the protrusion and the engagement part of each engagement pair.

A cable protection and guiding device, which can protect and guide cables smoothly and reliably through a simple connection between a movable end clamp and a fixed end clamp in different installation and use environments. Wherein, when the coupling frame main bodies (10) are left and right engaged with each other upside down, the engagement error prevention protrusion (11e) prevents the connection by interfering with the coupling plate (11) engaged in the offset mode, the engagement prevention A wrong protrusion is provided on the surface of at least one of the pair of left and right coupling plates forming the coupling frame main body, and when the coupling frame main body is properly engaged with each other, the correctly connected area (11f) avoids contact with the coupling frame main body. The correctly connected region is provided on a surface of the coupling plate of the coupling frame body which faces the coupling error engaging protrusion which interferes with the engaging error preventing protrusion.

The present invention relates to a lower thread supply device for a sewing machine, comprising: a housing (100) which is fixed to a main body of a sewing machine, has a cylindrical shape in which a front side and a back side are opened along a central axis, and has a (a housing cut out portion)(110) formed by cutting the outer circumferential surface of one side; a rotation plate (200) which is connected to a power shaft of a sewing machine, has a disk shape, has a power transmission protrusion (210) formed on the front surface of the disk, and is provided at the back inner lateral side of the housing (100) to rotate; a hook body (300) which is rotatably provided inside the housing (100), has a cylindrical shape with an opened front side, a protrusion receiving part (320) formed at the back outer portion to receive the torque of the rotation plate (200) by being engaged with the power transmission protrusion (210), a bobbin mounting post (330) formed at the back inner portion, and a hook (310) that passes through the loop formed by an upper thread descending along a needle of a sewing machine, thereby pulling the upper thread, provided at the outer circumferential surface of one side; a spool-shaped bobbin (400) which is inserted into the bobbin mounting post (330) of the hook body (300) to be rotatably provided, and to which a lower thread is wound; and a cap (500) which passes through the center of the bobbin (400) to be detachably coupled to the bobbin mounting post (330), thereby preventing the separation of the bobbin from the hook body (300).

The invention relates to a device for conveying products (2), particularly food products, consisting of a horizontal conveying path supported by a base and having a drive means (1) substantially extending in the horizontal direction, wherein the drive means (1) is reversibly driven, and is associated with at least one auxiliary conveyor device (3, 4) also supported by the base, said device havinga conveying means (5) for the product (1) driven by the drive means, and having supporting means (3, 4) by means of which the product (1) is laterally supported and carried at a distance from the drive means (1).

The invention provides an air conditioner which comprises a main body, a blade and a blade driving unit. The main body restricts an air inlet and an air outlet. The blade is connected to the main body through a hinge by rotatable manner for opening and closing the air outlet. The blade driving unit is connected to the part of the blade separated from the hinge for driving the blade.

A keyboard chassis capable of preventing deformation of the keyboard chassis even when the keyboard instrument is stored in an upright position, and a key guide structure capable of stably guiding a key without generating noise. The keyboard chassis is provided with a plurality of connection parts connecting between a rear support part and a front support part. Each connection part includes a plate-shaped vertical rib continuous with the rear support part and the front support part, and a plate-shaped reinforcement rib disposed on an upper end of the vertical rib, with a width increased in the left-right direction. The key guide structure includes key guide holders each having a mounting portion, and key guide bodies each mounted in the mounting portions in a state inserted from above, for being brought into sliding contact with inner side surfaces of a guide recess of each key.

A screen device, comprising a screen guide simple in structure, stable in operation, and formable in a linear rail shape in a drawn-out state. The screen guide (12) further comprises a large number of guide blocks (14) formed in a generally U-shape by a bottom part (14a) along the end part of a screen (4) and a vertical wall part (14b) along the outer surface of the screen. A through hole (14c) is formed along the tip part of the vertical wall part, a series of wire member (16) is passed through the through hole, and when the screen guide is drawn out along the end part of the screen, the continuously connecting surfaces of the adjacent guide blocks (14) are brought into contact with each other.

The invention relates to a bicycle chain-mounting mechanism which is arranged on the wheel surface of a chain wheel, a plurality of wheel teeth are arranged on the periphery of the chain wheel, and each wheel tooth is composed of a tooth peak and a tooth valley. The bicycle chain-mounting mechanism is characterized by comprising at least one chain avoiding groove formed between the first wheel tooth and the second wheel tooth adjacent to the first wheel tooth, wherein the chain avoiding groove extends from the tooth peak of the first wheel tooth to the tooth valley of the second wheel tooth, the chain avoiding groove is provided with a first side wall on the first wheel tooth, and the extending line of the first side wall passes through the middle portion of the top of the tooth peak of the first wheel tooth. Thus, the chain avoiding groove has the appropriate width, and therefore not only can stable chain mounting actions be kept, but also the appropriate thicknesses and strength of the wheel teeth can be guaranteed.

The invention relates to a power tool (1) which is designed as a jigsaw (2) and which comprises a rear support (20) for the saw blade (8) at a right angle to the rotational axis (22) of the saw blade (8). Said support (20) is designed as an element that is carried along by the saw blade in the rotational direction.

A medium transportation apparatus includes a fixed member fixed to an apparatus main body, and a switching guide for guiding a medium.
