There have been known small-sized electronic devices in which a battery such as a
primary battery and a secondary battery is used as a power supply of a video recorderwith an integrated camera, a transceiver, or the like. Since these batteries are easily
obtainable, users can use the batteries lightheartedly and the use thereof can befacilitated. However, general users do not understand very well that the usable time of
the batteries is significantly affected by temperature. When a user uses a small-sized
electronic device including such a battery in a low-temperature condition such as, forexample, a skiing area or a snowy mountain and the usable time of the battery isextremely reduced, therefore, the user has concern that the device may had amalfunction.
[0003]
In practice, the usable time under a low-temperature environmental at or below 0 degrees
Celsius can be reduced to approximately 1/2 or shorter of the usable time under anormal-temperature environment around 20 degrees Celsius, for example. As one
example, the difference in the duration time of a size AA alkaline battery between an
environment at 25 degrees Celsius and an environment at 10 degrees Celsius isapproximately 1/2 to 1/4.
[0004]In order to solve such a problem, there has been proposed a battery with a packing
member for distribution whose surface is provided with thermal behavior displaying means
made of a temperature-sensitive material that changes its color according totemperature. A surface of the battery is also provided with such thermal behavior
displaying means made of a temperature-sensitive material that changes its color
according to temperature. Thereby, users can recognize the temperature at which thebattery is being used according to the color change of the thermal behavior displaying
means. By showing the usable time according to temperature, the use of the battery byusers can be facilitated.

FIG. 1 is a perspective view of an intermediate member 120 to which a collimation lens isbonded and fixed. The intermediate member 120 of Example 1 is provided, on a front side
and a back side thereof, with recesses 121a and 121b which correspond to the shape ofthe collimation lens and to which the collimation lens is bonded. The intermediate
member 120 is further provided with through holes 124 near each end of a main scanning
direction for receiving screws. One of the through holes 124 is disposed linesymmetrically relative to the other through hole based on a line in a direction of an opticalaxis running through the center of the intermediate member 120 in the main scanning
direction. With the arrangement of the through holes 124, the intermediate member 120
can be attached to the housing at an angle 180 degrees different around the optical axis
from the angle of the previous attachment of the intermediate member 120, when theoptical scanner is reused. Thus, the recess 121b on the back side of the intermediate
member without a bonding adhesive can be used as a new surface to which the lens is1

bonded.
[0031]
Preferably, surfaces of the recesses 121a and 121b are roughened so that the surface
areas thereof will be larger than the area of an external peripheral surface of thecollimation lens. When the surface areas of the recesses 121a and 121b are larger than
the surface area of the collimation lens, the bonding adhesive can be prevented frombeing left in the recesses 121a and 121b and adhering to the collimation lens.

a fixed hub (5) fixed to the first end of the umbrella shaft (1);umbrella ribs radially fixed to the fixing hub (5);a movable hub (2) being movable in an axial direction of the umbrella shaft (1); andauxiliary ribs (3) for connecting the movable hub (2) and the umbrella ribs,
the umbrella ribs comprising:a plurality of connection ribs (6), one end of each connection rib (6) being
rotatably fixed to a periphery of the fixed hub (5);a plurality of drive levers (7), one end of each drive lever (7) being
rotatably fixed to the other end of each connection rib (6); anda plurality of main ribs (4), a middle portion in its axial direction of eachmain rib (4) being rotatably fixed to the other end of each drive lever (7),the auxiliary ribs (3) axially supporting intersections between the connection ribs(6) and the main ribs (4), one end of each auxiliary rib (3) being rotatably fixed to a
periphery of the movable hub (2), the other end of each auxiliary rib (3) being rotatably
fixed to one end of each main rib (4) at a fixed hub side.
