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.

Claims

1. A portable electronic device comprising:

a battery housing having, at one end of the battery housing, an opening to/from which a battery is allowed to be inserted/detached, and in which the battery is detachably housed;

a long member whose one end is fixed and which is routed in the battery housing, can be drawn by an operation of drawing the other end, and can be pushed to the deepest place in the insertion direction in the battery housing by an operation of inserting the battery whose battery front end face comes into contact with the long member; and

guide parts provided on both side walls of the battery housing and, when the long member is drawn by the drawing operation, making the long member cross the battery housing so as to be stretched in a position where the battery can be taken out.

2. The portable electronic device according to claim 1, wherein the guide parts are provided in positions to make the long member cross the battery housing in a stretched state in a direction orthogonal to the insertion/detachment direction.

3. The portable electronic device according to claim 1, wherein the guide parts are formed as slits which are formed in the side walls and in which the long member is inserted.

4. The portable electronic device according to claim 1, wherein as the guide parts, back-side ends of guide members are used, the guide members being provided along an insertion direction on the side walls and in which the long member is inserted.

5. The portable electronic device according to claim 1, further comprising a device-side connector to which a battery-side connector in the batter front end face can be inserted, in the deepest place in the insertion direction of the battery housing,

wherein the guide parts are provided in positions to set a position of contact with the battery front end face, of the long member in the stretched state so that the long member do not come into contact with the battery-side connector.

6. The portable electronic device according to claim 1, further comprising an outlet which is provided near the opening and from which the other end of the long member is insertably drawn to the outside, and

a three-dimensional tab, at the other end of the long member, whose entry to the outlet is not limited.

7. The portable electronic device according to claim 6, wherein the tab has a three-dimensional shape larger than a gap between the battery and an inner face of the battery housing and provided in a position where length from the outlet is smaller than length in the insertion direction of the battery in the case where the long member is drawn at the maximum, and

in the case where the tab exists in the battery housing, operation of loading the battery to a normal position is disturbed by the tab.

8. The portable electronic device according to claim 1, further comprising a cover member capable of closing the opening,

wherein the tab can be housed in a space formed by a rear end face of the battery housed in the battery housing and the cover member.

9. The portable electronic device according to claim 1, further comprising a slide drawing mechanism coupled to the other end of the long member and drawing the long member.

10. The portable electronic device according to claim 9, further comprising a cover member capable of covering the opening and the slide drawing member.

11. The portable electronic device according to claim 1, further comprising an elastic member which is provided on a wall face in the insertion direction orthogonal to both side walls forming the battery housing, has biasing force by which the elastic member fits in a recess formed in an outer face of a loaded battery, and elastically fits in the recess.

12. The portable electronic device according to claim 1, further comprising a rib which is provided on a wall face in the insertion direction orthogonal to both side walls forming the battery housing and slidably fits in a guide groove formed in an outer face of a battery and parallel with the insertion direction.

13. The portable electronic device according to claim 1, wherein the long member is a band-shaped member.

14. A capsule endoscope diagnosis system comprising:

a capsule endoscope which includes an image capturing unit, an illuminating unit capable of illuminating an image capturing region, and a transmitting unit capable of sending image data captured by the image capturing unit to the outside and can be swallowed by a subject;

a detector having an antenna structure attached to the body surface of the subject and receiving image data transmitted from the transmitting unit as a predetermined electric displacement amount; and

a portable electronic device including;

a battery housing having, at one end of the battery housing, an opening to/from which a battery is allowed to be inserted/detached, and in which the battery is detachably housed;

a long member whose one end is fixed and which is routed in the battery housing, can be drawn by an operation of drawing the other end, and can be pushed to the deepest place in the insertion direction in the battery housing by an operation of inserting the battery whose battery front end face comes into contact with the long member; and

guide parts provided on both side walls of the battery housing and, when the long member is drawn by the drawing operation, making the long member cross the battery housing so as to be stretched in a position where the battery can be taken out, wherein the electronic device is carried by the subject with the battery loaded in the battery housing, and stores the image data received by the detector.
