  • Patent number: 8372001
    Abstract: The present invention is directed to reliably prevent a trouble that a battery is loaded either in a state where a ribbon is entirely housed in a battery housing or without a ribbon by a simple method using a ribbon. Guide parts (83, 84) are provided on both side walls (57, 58) of a battery housing (53). A ribbon (81) is set so as to cross the battery housing (53) in a stretched state by the guide parts (83, 84) in a position where the battery can be taken out by drawing the ribbon (81). With the configuration, at the time of loading a battery, by making the ribbon (81) extend outside, the ribbon (81) is not entirely housed in the battery housing (53) or absence of the ribbon (81) in the battery housing (53) can be prevented. By making the battery front end face come into contact with the stretched ribbon (81) and inserting a battery, a normal loading state in which the ribbon (81) is pushed to the deepest place can be assured. The battery ejecting function with a simple ribbon (81) can be reliably displayed.

  • Patent number: 7856676
    Abstract: A capsule-type medical device collector has a cylindrical net member (61a) whose mesh size is formed so as to be able to collect a capsule endoscope (3), slits 61d and (61d), an INSULOCK binder (61e), and handle members 61f and (61f). By binding the other end of the cylindrical net member (61a) with the INSULOCK binder (61e) to form the cylindrical net member (61a) in a bag shape and sandwiching ear members (61a1) and (61a1) of the cylindrical net member (61a) between a toilet stool (7) and a toilet seat (71), the cylindrical net member (61a) is fixed on the toilet stool (7). After excretion, the cylindrical net member (61a) is taken out and only a capsule endoscope (3) is collected. In such a manner, a capsule-type medical device discharged from a subject to the outside is easily collected.

  • Publication number: 20090118576
    Abstract: An object of the invention is to eliminate unstable behavior of a drawn cable connected to a portable medical apparatus, which is of a storage target, to prevent cable jam or looseness and cable disconnection. A bundling member (13) is an example of a constraint member which constrains paths of cables (5) drawn from an opening (44) of a pouch (41) in which a receiver (6) is stored. The bundling member (13) has a joint structure in which a surface fastener is used between a flap (46) and a backside of the pouch (41), and the bundling member (13) bundles the cables (5) drawn from the opening (44). The bundling member (13) is constrained by clamping the bundling member (13) at a portion of a joint structure (48). Therefore, unstable behavior of the cable (5) can be eliminated to prevent jam or looseness of the cable (5), and steep bending can be eliminated at a base portion where the cable (5) is drawn from the receiver (6) to protect the cable (5).

  • Patent number: 6920343
    Abstract: The present invention provides a mobile information terminal apparatus, wherein a power supply terminal formed from a wire having elasticity, in which an electrode contact section is provided between two twisted coil springs, is brought into contact with an electrode of a battery so that feeding is carried out. This realizes a terminal, which does not easily reach the yield point against the degree of deformation caused by an impact with use of its characteristics provided from the wire material, in which the degree of a change in spring force is small against movement of the battery, and which has an excellent following-up property. Accordingly, the mobile information terminal apparatus according to the invention prevents interruption of feeding, or contact failure, etc. caused by an external impact, etc. from occurring therein.

  • Patent number: 6897852
    Abstract: There has been a problem with a film provided on a surface of an input section such as a touch panel etc., which is arranged on a display such as a conventional type of liquid crystal display or the like is swelled or corrugated owing to deterioration with the lapse of time, or change in temperature and humidity. According to the present invention, there is provided an information input display device. The device comprises a drawing action section which generates tension to draw outward directly or indirectly by elasticity in a film, when an input section capable of displaying in a transmittable manner, which is arranged on a surface of a display section, is attached to an housing. The device prevents swelling or corrugation of the film from occurring by the tension.

  • Publication number: 20040195783
    Abstract: A waterproof structure that is provided on a device includes a waterproof member. A pipe with no flash of a parting line, which is formed by extrusion-molding an elastic material such as a rubber or a resin, is used as the waterproof member. The waterproof member is interposed at a coupling part between members that is to be waterproofed, such that terminal-end faces of the pipe are disposed to be opposed to each other with their center (axes) being aligned (coaxial). When pressure is applied by engagement between the to-be-waterproofed members, the terminal-end faces of the pipe are put in close contact with each other. Alternatively, terminal-end portions of the pipe are juxtaposed with their centers being made parallel, and when pressure is applied, side faces of the terminal-end portions are put in close contact with each other. Thus, waterproofing is effected.
